High-resolution genome mapping and functional dissection of chlorogenic acid production in Lonicera maackii.

Amur honeysuckle (Lonicera maackii) is a widely used medicinal plant of the Caprifoliaceae family that produces chlorogenic acid. Research on this plant mainly focuses on its ornamental value and medicinal compounds, but a reference genome sequence and molecular resources for accelerated breeding are currently lacking. Herein, nanopore sequencing and high-throughput chromosome conformation capture (Hi-C) allowed a chromosome-level genome assembly of L. maackii (2n = 18). A global view of the gene regulatory network involved in the biosynthesis of chlorogenic acid and the dynamics of fruit coloration in L. maackii was established through metabolite profiling and transcriptome analyses. Moreover, we identified the genes encoding hydroxycinnamoyl-CoA quinate transferase (LmHQT) and hydroxycinnamoyl-CoA shikimic/quinate transferase (LmHCT), which localized to the cytosol and nucleus. Heterologous overexpression of these genes in Nicotiana benthamiana leaves resulted in elevated chlorogenic acid contents. Importantly, HPLC analyses revealed that LmHCT and LmHQTs recombinant proteins modulate the accumulation of chlorogenic acid (CGA) using quinic acid and caffeoyl CoA as substrates, highlighting the importance of LmHQT and LmHCT in CGA biosynthesis. These results confirmed that LmHQTs and LmHCT catalyze the biosynthesis of CGA in vitro. The genomic data presented in this study will offer a valuable resource for the elucidation of CGA biosynthesis and facilitating selective molecular breeding.

Traditional Chinese Medicine in Treatment of Diabetic Kidney Disease Based on Wnt/β-catenin Signaling Pathway： A Review / 中国实验方剂学杂志

Diabetic kidney disease （DKD） is a common complication of diabetes and a leading cause of end-stage kidney disease. Its pathogenesis is complex， and it presents a significant challenge in treatment， gradually becoming a major global public health issue. One of the main pathological changes in DKD is tubulointerstitial fibrosis， clinically characterized by proteinuria and declining kidney function， which severely impacts the daily life of patients. Currently， western medicine commonly uses methods such as controlling blood sugar and blood pressure， and reducing proteinuria to treat DKD， but the efficacy is unsatisfactory， and there are many side effects. As reported， traditional Chinese medicine （TCM） treatment for DKD has many advantages， such as low cost， significant efficacy， and minimal adverse reactions. More researchers focusing on DKD are turning their attention to TCM， and progress has been made in related studies both in China and abroad. The Wnt/β-catenin signaling pathway is relatively evolutionarily conserved and plays a crucial role in normal biological development and the entire life process. Studies have demonstrated that abnormal activation of the Wnt/β-catenin signaling pathway is related to renal fibrosis， which coincides with TCM theory of "collateral diseases". By reviewing relevant literature， this article reviewed the Wnt/β-catenin signaling pathway and its role in DKD and summarized the research status of TCM monomers， single drug extracts， and TCM formulas in improving renal fibrosis and treating DKD through the improvement of glomerular mesangial cells， renal tubular epithelial cells， and podocyte injury， aiming to provide new ideas and directions for TCM treatment of DKD.

Effects of electroacupuncture on NLRP3/Caspase-1/GSDMD axis and neurological function in rats with cerebral ischemic reperfusion / 中国针灸

OBJECTIVE@#To investigate the neuroprotective effect of electroacupuncture (EA) at "Quchi" (LI 11) and "Zusanli" (ST 36) in the rats with cerebral ischemic reperfusion and the potential mechanism of microglia pyroptosis.@*METHODS@#Sixty SD rats were randomly divided into a sham-operation group, a model group and an EA group, with 20 rats in each group. The Zea Longa method was employed to establish the rat model of the middle cerebral artery occlusion and reperfusion (MACO/R) in the left brain. In the EA group, since the 2nd day of modeling, EA was given at "Quchi" (LI 11) and "Zusanli" (ST 36) of right side with disperse-dense wave, 4 Hz/20 Hz in frequency and 0.2 mA in current intensity, 30 min each time, once a day for lasting 7 consecutive days. The reduction rate of cerebral blood flow was measured with laser Doppler flowmetry during operation. The neurological function of rats was observed using Zea Longa neurobehavioral score. The cerebral infarction volume was detected by TTC staining method. The microglia positive expression in the ischemic side of the cortex was detected with the immunofluorescence method. Under transmission electron microscope, the ultrastructure of cell in the ischemic cortex was observed. The mRNA expression levels of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), cysteinyl aspartate specific proteinase-1 (Caspase-1) and gasdermin D (GSDMD) in the ischemic cortex were detected using real-time PCR.@*RESULTS@#Compared with the sham-operation group, in the model group, the reduction rate of cerebral blood flow was increased during operation (P<0.001); Zea Longa neurobehavional score and the percentage of cerebral infarction volume were increased (P<0.001), the numbers of M1-type microglia marked by CD68+ and M2-type microglia marked by TMEM119+ were elevated in the ischemic cortex (P<0.001), the mRNA expression of NLRP3, ASC, Caspase-1 and GSDMD was increased (P<0.001, P<0.01); the cytomembrane structure was destroyed, with more cell membrane pores formed in the ischemic cortex. Compared with the model group, after intervention, Zea Longa neurobehavioral score and the percentage of cerebral infarction volume were reduced (P<0.05), the number of M1-type microglia marked by CD68+ was reduced (P<0.05) and the number of M2-type microglia marked by TMEM119+ was increased (P<0.05); and the mRNA expression of NLRP3, ASC, Caspase-1 and GSDMD was decreased (P<0.01, P<0.05) in the EA group. Even though the cytomembrane structure was incomplete, there were less membrane pores presented in the ischemic cortex in the EA group after intervention.@*CONCLUSION@#The intervention with EA attenuates the neurological dysfunction and reduces the volume of cerebral infarction in the rats with cerebral ischemic reperfusion. The underlying mechanism is related to the inhibition of microglia pyroptosis through modulating NLRP3/Caspase-1/GSDMD axis.

Bloodletting Acupuncture at Jing-Well Points Alleviates Myocardial Injury in Acute Altitude Hypoxic Rats by Activating HIF-1α/BNIP3 Signaling-Mediated Mitochondrial Autophagy and Decreasing Oxidative Stress / 中国结合医学杂志

OBJECTIVE@#To explore the protective effect and possible mechanisms of bloodletting acupuncture at Jing-well points (BAJP) pre-treatment on acute hypobaric hypoxia (AHH)-induced myocardium injury rat.@*METHODS@#Seventy-five rats were randomly divided into 5 groups by a random number table: a control group (n=15), a model group (n=15), a BAJP group (n=15), a BAJP+3-methyladenine (3-MA) group (n=15), and a BANA (bloodletting at nonacupoint; tail bleeding, n=15) group. Except for the control group, the AHH rat model was established in the other groups, and the corresponding treatment methods were adopted. Enzyme-linked immunosorbent assay (ELISA) was used to detect creatine kinase isoenzyme MB (CK-MB) and cardiac troponins I (CTnI) levels in serum and superoxide dismutase (SOD) and malondialdehyde (MDA) levels in myocardial tissue. Hematoxylin-eosin (HE) staining was used to observe myocardial injury, and terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling (TUNEL) staining was used to observe cell apoptosis. Transmission electron microscopy detection was used to observe mitochondrial damage and autophagosomes in the myocardium. The mitochondrial membrane potential of the myocardium was analyzed with the fluorescent dye JC-1. Mitochondrial respiratory chain complex (complex I, III, and IV) activities and ATPase in the myocardium were detected by mitochondrial respiratory chain complex assay kits. Western blot analysis was used to detect the autophagy index and hypoxia inducible factor-1α (HIF-1α)/Bcl-2 and adenovirus E1B 19k Da-interacting protein 3 (BNIP3) signaling.@*RESULTS@#BAJP reduced myocardial injury and inhibited myocardial cell apoptosis in AHH rats. BAJP pretreatment decreased MDA levels and increased SOD levels in AHH rats (all P<0.01). Moreover, BAJP pretreatment increased the mitochondrial membrane potential (P<0.01), mitochondrial respiratory chain complex (complexes I, III, and IV) activities (P<0.01), and mitochondrial ATPase activity in AHH rats (P<0.05). The results from electron microscopy demonstrated that BAJP pretreatment improved mitochondrial swelling and increased the autophagosome number in the myocardium of AHH rats. In addition, BAJP pretreatment activated the HIF-1α/BNIP3 pathway and autophagy. Finally, the results of using 3-MA to inhibit autophagy in BAJP-treated AHH rats showed that suppression of autophagy attenuated the treatment effects of BAJP in AHH rats, further proving that autophagy constitutes a potential target for BAJP treatment of AHH.@*CONCLUSION@#BAJP is an effective treatment for AHH-induced myocardial injury, and the mechanism might involve increasing HIF-1α/BNIP3 signaling-mediated autophagy and decreasing oxidative stress.

Traditional Chinese Medicine Treats Chronic Atrophic Gastritis via Multiple Pathways / 中国实验方剂学杂志

ObjectiveTo mine the compatibility rules of patented traditional Chinese medicine (TCM) compound prescriptions for treating chronic atrophic gastritis (CAG) by systems pharmacology and molecular docking methods, and predict the targets and molecular mechanisms of Chinese medicinals with different efficacy in the treatment of CAG. MethodThe TCM compound prescriptions for treating CAG were extracted from the patent system of the China National Intellectual Property Administration. The active components and targets of the prescriptions were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Traditional Chinese Medicine Integrative Database (TCMID), and UniProt. The candidate targets and pathways of CAG were obtained from GeneCards, DisGeNet, Online Mendelian Inheritance in Man (OMIM), MalaCards, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Reactome. The gene ontology (GO) functional annotation and KEGG pathway enrichment were realized by R Studio 4.1.2. STRING11.0 was employed to build the protein-protein interaction (PPI) network, and AutoDock Vina 4.2.6 was used for the docking between key targets and components. ResultA total of 228 TCM compound prescriptions for treating CAG were extracted. The medicinals used in these prescriptions mainly had warm or cold nature, bitter or sweet taste, tropism to the spleen, stomach, and liver meridians, and the efficacy of tonifying Qi, regulating Qi movement, clearing heat, and activating and toniying blood. The prescriptions mainly treated CAG via p53, mitogen-activated protein kinase (MAPK), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), forkhead box protein O (FoxO), vascular endothelial growth factor (VEGF), and hypoxia-inducible factor-1 (HIF-1) signaling pathways. Molecular docking results confirmed that the active components in the prescriptions had docking activities with key receptor proteins. ConclusionThis study preliminarily analyzed the compatibility rules of TCM compound prescriptions in the treatment of CAG. The medicinals with different efficacy treat CAG by regulating cell proliferation, apoptosis, and oxidative stress response, preventing carcinogen production, promoting gastric acid secretion, and improving local microcirculation in a multi-target, multi-pathway, multi-link manner. The findings facilitate the research on the TCM treatment of CAG.

HbA1c comparison and diagnostic efficacy analysis of multi center different glycosylated hemoglobin detection systems / 中华预防医学杂志

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R2 of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

A strategy combining collision cross section(CCS) prediction and quantitative structure-retention relationship(QSRR) model for quinoline and isoquinoline alkaloids was established based on UHPLC-IM-Q-TOF-MS and applied to Phellodendri Chinensis Cortex and Phellodendri Amurensis Cortex. The strategy included the following three steps.(1) The molecular features were extracted by the "find features" algorithm.(2) The potential quinoline and isoquinoline alkaloids were screened by filtering the original characteristic ions extracted from Phellodendri Chinensis Cortex and Phellodendri Amurensis Cortex by the established CCS vs m/z prediction interval.(3) According to the retention time of candidate compounds predicted by QSRR model, the chemical constituents were identified in combination with the characteristic fragment ions and pyrolysis law of secondary mass spectrometry. With the strategy, a total of 80 compounds were predicted, and 15 were identified accurately. The strategy is effective for the identification of small analogs of traditional Chinese medicine.

Detection value of clinical coagulation indexes in type 2 diabetic foot patients and the correlation analysis with pathological changes / 中华内分泌外科杂志

Objective:To explore the changes of coagulation index levels in patients with type 2 diabetic foot and their correlation with pathological changes, in order to provide reference for clinical diagnosis of diabetic foot.Methods:133 patients with type 2 diabetes admitted to the Xiaoshan Hospital of Traditional Chinese Medicine in Hangzhou from Jun. 2018 to Jun. 2020 were selected. The patients were divided into type 2 diabetes group ( n=65) and diabetes foot group ( n=68) according to whether they had diabetes feet. In addition, 60 patients who had health examinations in our hospital during the same period were selected as the control group. Fibrinogen (FIB), thrombin time (TT), activated partial thromboplastin time (APTT) and prothrombin time (PT) were compared in each group, and Spearman method was used to analyze the correlation between each index and the occurrence of diabetes foot. Area under curve (AUC) of working characteristics of subjects (ROC) was used to analyze the diagnostic value of each index in diabetes foot. Results:The average FIB of control group, type 2 diabetes group and diabetes foot group was (2.86±0.50) g/L, (3.30±0.81) g/L, (4.43±1.16) g/L; The FIB level in diabetes foot group was significantly higher than that in type 2 diabetes group and control group, and that in type 2 diabetes group was significantly higher than that in control group ( P<0.05) ; The mean TT of control group, type 2 diabetes group and diabetes foot group was (17.60±2.01) s, (15.39±2.39) s, (13.49±2.84) s; The average APTT of control group, type 2 diabetes group and diabetes foot group was (32.02±4.22) s, (29.97±3.97) s, (25.69±4.07) s; The mean PT values of control group, type 2 diabetes group and diabetes foot group were (12.64±1.49) s, (11.41±1.04) s and (10.50±1.08) s. The TT, APTT and PT values in the diabetes foot group were significantly lower than those in the type 2 diabetes group and the control group, and those in the type 2 diabetes group were significantly lower than those in the control group ( P<0.05) ; The level of FIB index was positively correlated with the occurrence of diabetes foot, while TT, APTT and PT indexes were negatively correlated with the occurrence of diabetes foot ( P<0.05). The AUC values of FIB, TT, APTT and PT indexes for the diagnosis of diabetes foot were 0.898, 0.879, 0.859 and 0.871, respectively. Conclusions:There are significant differences in FIB, TT, APTT and PT index levels between diabetic foot patients and type 2 diabetic patients and healthy people, and the occurrence of diabetic foot is significantly related to blood coagulation indicators. The detection of blood coagulation indicators has certain clinical significance for the diagnosis of diabetic foot.

Evolutionary Law of Syndrome and Syndrome Elements during the Malignant Transformation of Chronic Hepatitis B / 中医杂志

ObjectiveTo clarify the evolutionary laws of syndromes and syndrome elements at different stages during the malignant transformation of chronic hepatitis B （CHB）. MethodsA total of 671 patients with hepatitis B virus infection， who were admitted to the outpatient and inpatient departments of Dongzhimen Hospital of Beijing University of Chinese Medicine and The Fifth Medical Center of Chinese PLA General Hospital from July 1st， 2020 to June 30th， 2021， were included， involving 120 cases of CHB， 340 cases of hepatitis B liver cirrhosis （HBLC）， 64 cases of precancerous lesions with hepatitis B liver cirrhosis （PLHC）， and 147 cases of hepatitis B liver cirrhosis with hepatocellular carcinoma （HCC）. A Survey form of traditional Chinese medicine syndrome during malignant transformation of chronic hepatitis B was designed， and the general information， auxiliary examination and the four examinations results were collected. Factor analysis and K-means clustering were used to determine and statistically analyze the syndrome and syndrome elements. ResultsFive traditional Chinese medicine （TCM） syndrome types were identified in CHB patients， while there were six TCM syndrome types in HBLC， PLHC and HCC stages. Among CHB patients， the main syndromes were liver constraint and spleen deficiency （53.33%） and liver-gallbladder damp-heat （21.67%）， and the dominant syndrome elements were qi stagnation （27.60%）， heat （17.71%） and qi deficiency （17.71%）. In the HBLC stage， the syndromes were mainly blood stasis obstructing the collaterals （23.83%） and liver constraint and spleen deficiency （22.35%）， with dominant syndrome elements being blood stasis （19.25%）， dampness （17.46%）， and qi deficiency （15.01%）. For the PLHC stage， the primary syndrome types were blood stasis obstructing the collaterals （29.68%） and liver-kidney yin deficiency （20.31%）， and the leading syndrome elements were blood stasis （22.12%）， yin deficiency （15.93%）， and qi deficiency （15.04%）. In the HCC stage， the syndrome was dominated by blood stasis obstructing the collaterals （33.34%） and liver-kidney yin deficiency （19.73%）， with the main syndrome elements being blood stasis （24.52%）， yin deficiency （16.09%）， and qi deficiency （15.33%）. During the progression of CHB to malignancy， there was a gradual decrease in excess syndromes including liver-gallbladder damp-heat and water-dampness internal obstruction from 21.67% to 19.04%. In contrast， deficiency syndromes including liver-kidney yin deficiency and spleen-kidney yang deficiency increased from 15.83% to 31.97%. Additionally， excess syndrome elements including qi stagnation， heat and dampness decreased from 59.89% to 34.48%， while deficiency syndrome elements including qi deficiency， yin deficiency and yang deficiency increased from 32.30% to 41.00%. ConclusionDuring the malignant transformation of CHB， there exists a progression of syndrome and syndrome elements， shifting from qi stagnation， heat and qi deficiency to blood stasis （predominantly excess）， dampness and qi deficiency， and then to blood stasis （predominantly deficiency）， yin deficiency and qi deficiency， characterized by “deficiency-excess complex， and shift from excess to deficiency”.

Reflections on Social Work Helps to Narrative Medicine Practice in China / 中国医学伦理学

Modern medical model advocates holistic medical treatment and holistic care, which transforms the concern about diseases in traditional medicine into the concern about people in modern medicine. Narrative medicine, as a tool for practicing holistic medical treatment and holistic care, runs through the whole process of patients’ entering medical procedures. It not only meets the needs of patients’ disease-related narratives, but also provides a new and more comprehensive way of communication for both doctors and patients, which is helpful to promote the comprehensive recovery of patients and the healthy development of doctor-patient relationship. At present, narrative medicine is facing some difficulties in the process of local practice in China. Social work, as one of the main bodies of multi-disciplinary and inter-professional cooperation in the medical field, can give full play to its professional advantages to help the new exploration of narrative medicine practice in China.

Cross-sectional study on the sleep status and risk factors for sleep problems in infants and young children in Jilin Province / 中国当代儿科杂志

OBJECTIVES@#To explore the sleep status and risk factors for sleep problems in infants and young children in Jilin Province.@*METHODS@#A total of 1 080 healthy infants and young children aged 0-3 years from eight prefecture-level cities and one autonomous prefecture in Jilin Province were selected as subjects. A self-designed questionnaire was used to collect the general information of the subjects, and the Brief Infant Sleep Questionnaire was used to understand the sleep status of the subjects. Multivariate logistic regression analysis was used to analyze the risk factors for sleep problems.@*RESULTS@#The total detection rate of sleep problems in the infants and young children was 38.24% (413/1 080). The total sleep time in the 4-11 month, 12-24 month, and 25-36 month age groups was higher than the recommended total sleep time (P<0.05). Multivariate logistic regression analysis showed that full-term birth, higher educational level of the main caregiver, and higher daytime activity intensity were protective factors for sleep problems in the infants and young children (P<0.05), while lower frequency of vitamin D supplementation, frequent night feeding, and maternal snoring were risk factors for sleep problems (P<0.05).@*CONCLUSIONS@#The total sleep time of infants and young children over 4 months old in Jilin Province is higher than the recommended total sleep time, but the prevalence rate of sleep problems is higher. The occurrence of sleep problems is related to various factors. Strengthening follow-up on preterm infants, providing education on infant sleep knowledge to primary caregivers, and regularly supplementing with vitamin D can be beneficial in reducing sleep problems in infants and young children.

Effect and mechanisms of Polygonatum kingianum (polygonati rhizome) on wound healing in diabetic rats.

ETHNOPHARMACOLOGICAL RELEVANCE: Diabetic dermatopathy is one of the most serious and common complications of diabetes. It has been found that high glucose can lead to abnormal glycometabolism. The skin microenvironment pollution caused by the increase in glucose and the oxidative stress mediated by the deposition of advanced glycation end products can lead to invisible skin injury, and the interaction between them is the key factor that makes the skin wounds of diabetic rats difficult to heal. Therefore, the main task of promoting healing is to reduce blood glucose levels and relieve the deposition of advanced glycation end products. Polygonatum kingianum Collett & Hemsl (PK) of Asparagaceae is planted in Yunnan, China, and is used by the Bai, Hani and Wa nationalities as a traditional medicine for preventing and treating diabetes. AIM OF THE STUDY: To study the effects of PK extract on skin wound healing in diabetic rats and to explore the regulatory mechanism of PK on wound microenvironment pollution, the antioxidative stress signaling pathway and latent injury of wound skin tissue. METHODS: First, wounds were prepared after diabetic rats were given PK extract by gavage for 4 weeks, and then gavage was continued for 2 weeks to observe and calculate the wound healing rate. A scanning electron microscope was used to observe the pathomorphological changes in the skin tissue at the edge of the wound. Western blotting was used to detect protein expression. Immunohistochemistry was used to detect the expression of CD34, AGEs, bFGF and VEGF. The Nrf2/HO-1 signaling pathway in skin tissue was detected by fluorescence quantitative PCR. Serum biochemical indicators and inflammatory cytokine levels were detected by a kit. RESULTS: After PK treatment, the wound healing rate increased significantly (P < 0.001), the infiltration of inflammatory cells in skin tissue of DM lesion rats decreased, the number of new blood vessels increased, and the epidermis and dermis thickened. The content of glucose, AGEs, RAGE protein and RAGE mRNA in skin decreased significantly (P < 0.05, P < 0.01, P < 0.001), while the expression of Nrf2 mRNA, HO-1 mRNA, CD34, bFGF and VEGF increased significantly (P < 0.05, P < 0.01, P < 0.001). The levels of SOD, GSH, MMP-9 and MMP-2 in skin decreased (P < 0.05, P < 0.01, P < 0.001), but the level of TIMP-2 increased (P < 0.001). GSP, GHb and ICAM-1 in plasma decreased (P < 0.05, P < 0.01, P < 0.001), while T-AOC, SOD and FINS increased (P < 0.05, P < 0.01). The levels of MDA, TNF-, IL-6, IL-2 and IFN-γ in plasma and wound skin tissue decreased (P < 0.05, P < 0.01, P < 0.001). CONCLUSION: PK can reduce the infiltration of inflammatory cells and glucose content in the skin tissue at the edge of the wound, reduce inflammatory factors in skin and plasma, and increase angiogenesis, thus improving the wound healing rate. PK can alleviate the microenvironment pollution caused by AGEs and glucose metabolism disorder in diabetic rats and induce antioxidant activity through the Nrf 2/HO-1 signaling pathway, thus reducing oxidative damage and offsetting endogenous skin damage and hidden damage.

Observation indicators: (1) age distribution, comorbidities and ACCI status of patients; (2) the grouping of ACCI and comparison of clinicopathological characteristics of patients in each group; (3) incidence of postoperative early complications and analysis of factors affecting postoperative early complications; (4) follow-up; (5) analysis of factors affecting the 3-year recurrence-free survival rate of patients. Follow-up was conducted using outpatient examination or telephone interview to detect postoperative survival of patients up to December 2020. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the nonparametric rank sum test. The X-Tile software (version 3.6.1) was used to analyze the best ACCI grouping threshold. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-Rank test was used for survival analysis. The Logistic regression model was used to analyze the factors affecting postoperative early complications. The COX proportional hazard model was used for univariate and multivariate analyses of factors affecting the 3-year recurrence-free survival rate of patients. Multivariate analysis used stepwise regression to include variables with P<0.05 in univariate analysis and variables clinically closely related to prognosis. Results:(1) Age distribution, comor-bidities and ACCI status of patients. Of the 242 patients, there were 28 cases with age <50 years, 68 cases with age of 50 to 59 years, 113 cases with age of 60 to 69 years, 33 cases with age of 70 to 79 years. There was 1 patient combined with mild liver disease, 1 patient combined with diabetes of end-organ damage, 2 patients combined with peripheral vascular diseases, 2 patients combined with peptic ulcer, 6 patients combined with congestive heart failure, 8 patients combined with chronic pulmonary diseases, 9 patients with diabetes without end-organ damage. The ACCI of 242 patients was 2 (range, 0-4). (2) The grouping of ACCI and comparison of clinicopathological characteristics of patients in each group. Results of X-Tile software analysis showed that ACCI=3 was the best grouping threshold. Of the 242 patients, 194 cases with ACCI <3 were set as the low ACCI group and 48 cases with ACCI ≥3 were set as the high ACCI group, respectively. Age, body mass index, cases with preoperative comorbidities, cases of American Society of Anesthesiologists classification as stage Ⅰ, stage Ⅱ, stage Ⅲ, tumor diameter, cases with tumor histological type as signet ring cell or poorly differentiated adenocarcinoma and cases with tumor type as moderately or well differentiated adenocarcinoma, cases with tumor pathological T staging as stage T1, stage T2, stage T3, stage T4, chemotherapy cycles were (58±9)years, (22.6±2.9)kg/m 2, 31, 106, 85, 3, (4.0±1.9)cm, 104, 90, 16, 29, 72, 77, 6(4,6) in the low ACCI group, versus (70±4) years, (21.7±2.7)kg/m 2, 23, 14, 33, 1, (5.4±3.1)cm, 36, 12, 3, 4, 13, 28, 4(2,5) in the high ACCI group, showing significant differences in the above indicators between the two groups ( t=-14.37, 1.98, χ2=22.64, Z=-3.11, t=-2.91, χ2=7.22, Z=-2.21, -3.61, P<0.05). (3) Incidence of postoperative early complications and analysis of factors affecting postoperative early complications. Of the 242 patients, 33 cases had postoperative early complications, including 20 cases with local complications and 16 cases with systemic complica-tions. Some patients had multiple complications at the same time. Of the 20 patients with local complications, 12 cases had abdominal infection, 7 cases had anastomotic leakage, 2 cases had incision infection, 2 cases had abdominal hemorrhage, 2 cases had anastomotic hemorrhage and 1 case had lymphatic leakage. Of the 16 patients with systemic complications, 11 cases had pulmonary infection, 2 cases had arrhythmias, 2 cases had sepsis, 1 case had liver failure, 1 case had renal failure, 1 case had pulmonary embolism, 1 case had deep vein thrombosis, 1 case had urinary infection and 1 case had urine retention. Of the 33 cases with postoperative early complications, there were 3 cases with grade Ⅰ complications, 22 cases with grade Ⅱ complications, 5 cases with grade Ⅲa complications, 2 cases with grade Ⅲb complications and 1 case with grade Ⅳ complica-tions of Clavien-Dindo classification. Cases with postoperative early complications, cases with local complications, cases with systemic complications were 22, 13, 9 in the low ACCI group, versus 11, 7, 7 in the high ACCI group, respectively. There were significant differences in cases with postoperative early complications and cases with systemic complications between the two groups ( χ2=4.38, 4.66, P<0.05), and there was no significant difference in cases with local complications between the two groups ( χ2=2.20, P>0.05). Results of Logistic regression analysis showed that ACCI was a related factor for postoperative early complications of gastric cancer patients undergoing laparoscopic radical gastrectomy [ odds ratio=2.32, 95% confidence interval ( CI) as 1.04-5.21, P<0.05]. (4) Follow-up. All the 242 patients were followed up for 36(range,1?46)months. During the follow-up, 53 patients died and 13 patients survived with tumor. The 3-year recurrence-free survival rate of the 242 patients was 73.5%. The follow-up time, cases died and cases survived with tumor during follow-up, the 3-year recurrence-free survival rate were 36(range, 2-46)months, 29, 10, 80.0% for the low ACCI group, versus 35(range, 1-42)months, 24, 3, 47.4% for the high ACCI group. There was a significant difference in the 3-year recurrence-free survival rate between the two groups ( χ2=30.49, P<0.05). (5) Analysis of factors affecting the 3-year recurrence-free survival rate of patients. Results of univariate analysis showed that preoperative comorbidities, ACCI, tumor diameter, histological type, vascular invasion, lymphatic invasion, neural invasion, tumor pathological TNM staging, postoperative early complications were related factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy [ hazard ratio ( HR)=2.52, 3.64, 2.62, 0.47, 2.87, 1.90, 1.86, 21.77, 1.97, 95% CI as 1.52-4.17, 2.22-5.95, 1.54-4.46, 0.27-0.80, 1.76-4.70, 1.15-3.12, 1.10-3.14, 3.01-157.52, 1.11-3.50, P<0.05]. Results of multivariate analysis showed that ACCI, tumor pathological TNM staging, adjuvant chemotherapy were indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy ( HR=3.65, 11.00, 40.66, 0.39, 95% CI as 2.21-6.02, 1.40-86.73, 5.41-305.69, 0.22-0.68, P<0.05). Conclusions:ACCI is a related factor for post-operative early complications of gastric cancer patients undergoing laparos-copic radical gastrectomy. ACCI, tumor pathological TNM staging, adjuvant chemotherapy are indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy.

A Data Mining-Based Study on Medication Rules of Chinese Herbs to Treat Heart Failure with Preserved Ejection Fraction / 中国结合医学杂志

OBJECTIVE@#To summarize the medication rules of Chinese herbs to treat heart failure with preserved ejection fraction (HFPEF) based on data mining and to provide references for clinical utilization.@*METHODS@#The China National Knowledge Infrastructure (CNKI), Wanfang database (Wanfang), VIP database (VIP), Chinese Biomedical Literature (CBM), PubMed, Embase, and Cochrane Library databases were searched from inception to October 2021 to identify relevant literature on treating HFPEF with Chinese herbs. Microsoft Excel 2019 was used to set up a database, and then, association rule analysis and hierarchical cluster analysis were performed by using apriori algorithm and hclust function respectively in R-Studio (Version 4.0.3).@*RESULTS@#A total of 182 qualified papers were included, involving a total of 92 prescriptions, 130 Chinese herbs, and 872 individual herbs prescribed, with an average of 9.5 herbs per prescription. The six most frequently prescribed herbs were Astragali Radix (Huangqi), Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Glycyrrhizae Radix Et Rhizoma (Gancao), Cinnamomi Ramulus (Guizhi), and Ginseng Radix Et Rhizoma (Renshen). There were 35 herbs used more than 5 times, involving 11 efficacy categories. The top three categories were deficiency-tonifying herbs, blood-activating and stasis-removing herbs, and dampness-draining diuretic herbs. The most commonly used herbs were mainly warm and sweet. The primary meridian tropisms were Lung Meridian, Heart Meridian and Spleen Meridian. Association rule analysis yielded 26 association rules, such as Astragali Radix (Huangqi) & Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Cinnamomi Ramulus (Guizhi) & Atractylodis Macrocephalae Rhizoma (Baizhu). Hierarchical cluster analysis yielded four herb classes, and their functions were mainly qi-replenishing and yang-warming, blood-activating and diuresis-inducing.@*CONCLUSIONS@#HFPEF is the syndrome of root vacuity and tip repletion, and its core pathogenesis is "deficiency", "stasis", and "water", with "deficiency" being the most principal, which is closely related to Xin (heart), Fei (Lung), and Pi (Spleen). The treatment of this disease occurs by improving qi, warming yang, activating blood and inducing diuresis. Astragali Radix (Huangqi) with Salviae Miltiorrhizae Radix Et Rhizoma (Danshen) is the basic combination of herbs applied.

Shexiang Baoxin Pill Regulates Intimal Hyperplasia, Migration, and Apoptosis after Platelet-Derived Growth Factor-BB-Stimulation of Vascular Smooth Muscle Cells via miR-451 / 中国结合医学杂志

OBJECTIVE@#To investigate the regulatory roles of Shexiang Baoxin Pill (SXBXW) in neointimal formation and vascular smooth muscle cells (VSMCs) invasion and apoptosis as well as the potential molecular mechanisms using cultured VSMCs model of vascular injury (platelet-derived growth factor (PDGF)-BB-stimulated) in vitro.@*METHODS@#VSMCs were randomly assigned to 5 groups: blank, PDGF-BB (20 ng/mL+ 0.1% DMSO), SXBXW-L (PDGF-BB 20 ng/mL + SXBXW low dose 0.625 g/L), SXBXW-M (PDGF-BB 20 ng/mL + SXBXW medium dose 1.25 g/L) and SXBXW-H (PDGF-BB 20 ng/mL+ SXBXW high dose 2.5 g/L) group. Cell proliferation was assessed using cell counting kit-8 (CCK-8) assay and bromodeoxyuridine (BrdU) incorporation assay, the migration effects were detected by Transwell assay, cell apoptosis rate was measured by the Annexin V/propidium iodide (PI) apoptosis kit. The markers of contractile phenotype of VSMCs were detected with immunofluorescent staining. To validate the effects of miR-451 in regulating proliferation, migration and apoptosis treated with SXBXW, miR-451 overexpression experiments were performed, the VSMCs were exposed to PDGF-BB 20 ng/mL + 0.1% DMSO and later divided into 4 groups: mimic-NC (multiplicity of infection, MOI=50), SXBXW (1.25 g/L) + mimic-NC, mimic-miR451 (MOI=50), and SXBXW (1.25 g/L) + mimic-miR451, and alterations of proteins related to the miR-451 pathway were analyzed using Western blot.@*RESULTS@#PDGF-BB induced VSMCs injury causes acceleration of proliferation and migration. SXBXW inhibited phenotypic switching, proliferation and migration and promoted cell apoptosis in PDGF-BB-induced VSMCs. In addition, miR-451 was shown to be down-regulated in the VSMCs following PDGF-BB stimulation. SXBXW treatment enhanced the expression of miR-451 in PDGF-BB-induced VSMCs (P<0.05). Compared with SXBXW + mimic-NC and mimic-miR451 groups, the expression of tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta (Ywhaz) and p53 was further reduced in SXBXW + mimic-miR451 group, while activating transcription factor 2 (ATF2) was increased in VSMCs (P<0.05).@*CONCLUSION@#SXBXW regulated proliferation, migration and apoptosis via activation of miR-451 through ATF2, p53 and Ywhaz in PDGF-BB-stimulated VSMCs.

Protective Effect of Tangshen Formula () on Interstitial Cells of Cajal in Colon of Diabetic Rats / 中国结合医学杂志

OBJECTIVE@#To explore the effect of Tangshen Formula (, TSF), a Chinese herbal medicine, on interstitial cells of Cajal (ICC) in the colon of diabetic rats.@*METHODS@#Fifty-four male Wistar rats were randomly divided into normal control (NC, n=14) and high-fat diet (HFD) groups (n=40). After 6 weeks, the rats in the HFD group were injected intraperitoneally streptozotocin once (30 mg/kg). Thirty rats with fasting blood glucose higher than 11.7 mmol/L were randomly divided into diabetes (DM) and TSF groups, 15 rats in each group. Rats in the NC and DM groups were intragastrically administered with saline, and those in the TSF group were given with TSF (2.4 g/kg) once daily for 20 weeks. Expression levels of Bax, Bcl-2, and caspase-3 in colonic smooth muscle layer were measured by Western blotting and immunohistochemical staining. The number of ICC was determined by immunohistochemical staining. Immunofluorescence was used for analyzing the ratio of classically activated macrophages (M1) and alternatively activated macrophages (M2) to total macrophages. Electron microscopy was used to observe the epithelial ultrastructure and junctions.@*RESULTS@#TSF appeared to partially prevented loss of ICC in DM rats (P<0.05). Compared with the NC group, expression levels of Bcl-2, Bax, caspase-3, and TNF-α as well as the ratio of M1 to total macrophages increased in DM rats (all P<0.05), and the ratio of M2 to total macrophages decreased (P<0.05 or P<0.01). Compared with the DM group, TSF decreased the expression levels of abovementioned proteins and restore M2 to total macrophages ratio (P<0.05 or P<0.01). TSF appeared to attenuate the ultrastructural changes of epithelia and improve the tight and desmosome junctions between epithelia reduced in the DM rats.@*CONCLUSION@#Reduced number of ICC in DM rats may be associated with damage of the intestinal barrier. The protective effects of TSF on ICC may be through repair of the epithelial junctions, which attenuates inflammation and inflammation-initiated apoptosis in colon of DM rats.

Effect of moxibustion on skin lesions and immune inflammatory response in psoriasis mice / 中国针灸

OBJECTIVE@#To observe the effect of moxibustion on skin lesions and immune inflammatory response in psoriasis mice, and to explore the possible mechanism of moxibustion for psoriasis.@*METHODS@#A total of 32 male BALB/c mice were randomly divided into a normal group, a model group, a moxibustion group and a medication group, 8 mice in each group. Psoriasis model was induced by applying 5% imiquimod cream on the back for 7 days in the model group, the moxibustion group and the medication group. At the same time of model establishment, the moxibustion group was treated with suspension moxibustion on skin lesions on the back, 20 min each time, once a day; the medication group was treated with 1 mg/kg methotrexate tablet solution by gavage, once a day. Both groups were intervened for 7 days. The daily changes of skin lesions were observed, and the psoriasis area and severity index (PASI) score was evaluated; the histopathological changes of skin lesions were observed by HE staining; the positive expression of proliferating cell nuclear antigen (PCNA) and T lymphocyte surface marker CD3 were detected by immunohistochemistry; the expression level of serum interleukin (IL) -17A was detected by ELISA, and the relative expressions of tumor necrosis factor-α (TNF-α), IL-1β and IL-6 mRNA in skin lesions were detected by real-time PCR.@*RESULTS@#The increased and hypertrophy scale, dry skin, red and swollen epidermis and obvious infiltration were observed in the model group, and each score and total score of PASI were higher than those in the normal group (P<0.01). The scale score, infiltration score, and total score of PASI in the moxibustion group were lower than those in the model group (P<0.01); the infiltration score and total score of PASI in the medication group were lower than those in the model group (P<0.01, P<0.05). The inflammatory cell infiltration in the model group was obvious, and the thickness of epidermal layer was increased compared with that in the normal group (P<0.01); the inflammatory cell infiltration and Munro micro abscess were decreased in the moxibustion group and the medication group, and the thickness of epidermal layer was decreased compared with that in the model group (P<0.01). Compared with the normal group, the positive cell number of PCNA and T was increased (P<0.01), and the body mass was decreased, and the spleen index was increased (P<0.01), and the expression of serum IL-17A and the relative expression of TNF-α, IL-1β and IL-6 mRNA in the skin lesions was increased in the model group (P<0.01). Compared with the model group, the positive cell number of PCNA and T was reduced (P<0.01), and the spleen index and the relative expression of TNF-α, IL-1β and IL-6 mRNA were reduced (P<0.01) in the moxibustion group and the medication group; the body mass of mice in the moxibustion group was higher than that in the model group (P<0.01); the content of serum IL-17A in the medication group was lower than that in the model group (P<0.01); the relative expression of TNF-α, IL-1β mRNA in the moxibustion group was higher than that in the medication group (P<0.01).@*CONCLUSION@#Moxibustion could effectively improve the scale and infiltration of skin lesions in psoriasis mice. Its mechanism may be related to inhibiting inflammatory response and regulating immunity.

Exploring theory of contemporary acupuncture manipulation and its application characteristics: in the perspective of acupuncture technique in Acupuncture and Moxibustion / 中国针灸

Through reviewing acupuncture technique in various editions of the state-compiled teaching material of Acupuncture and Moxibustion, the hierarchical structure, definitions, and variations of acupuncture manipulation were collected, the theory of contemporary acupuncture manipulation as well as its application characteristics were explored. In the perspective of the hierarchical structure, acupuncture technique with filiform needle is predominated. It is implied in the description of the definition of acupuncture technique that the devices of acupuncture have been developed from single form to multivariant one and the stimulation regions have no longer limited to acupoints. The types of acupuncture manipulations have been enriched gradually during the development of teaching materials. But a part of acupuncture manipulation have been deleted from the knowledge hierarchy of acupuncture technique in textbooks. Acupuncture and Moxibustion is comprehensive and normative, which is important in the inheritance and application of the theory of acupuncture and moxibustion. However, it has to some extent restricted the diversified development of knowledge on acupuncture manipulation.

Research progress on mechanism of acupuncture and moxibustion in treatment of irritable bowel syndrome / 中国针灸

The current clinical evidence and underlying mechanisms of acupuncture and moxibustion in the treatment of irritable bowel syndrome (IBS) were summarized, so as to better optimize clinical treatment. The relevant articles of acupuncture and moxibustion in the treatment of IBS in recent years were retrieved and summarized. We found that the clinical efficacy of acupuncture and moxibustion in the treatment of IBS was relatively reliable. However, the mutual relationships among various mechanisms of action such as abnormal gastrointestinal motility, high visceral sensitivity, intestinal microenvironment disorders, and abnormal intestinal-brain interactions need to be further explored. The authors believe that in-depth explorations of the bidirectional regulation of "gut-brain axis", the law of changes in the abundance and diversity of intestinal flora, and the establishment of a more ideal animal model of TCM syndrome differentiation are useful ideas for subsequent research.
