Traditional Chinese Medicine Regulates Autophagy to Prevent and Treat Osteoarthritis： A Review / 中国实验方剂学杂志

Osteoarthritis （OA） is a common chronic， highly prevalent， painful， and disabling degenerative joint disease. It has imposed a heavy burden on social healthcare and patients' psychology and economy due to its clinical symptoms such as impaired joint mobility and severe joint pain and the immature therapies. Studies have shown that OA is closely associated with articular cartilage dysfunction， synthesis and degradation disorders of chondrocyte extracellular matrix （ECM）， and joint inflammation. Moderate autophagy can restore the function of damaged chondrocytes， regulate chondrocyte apoptosis， and promote the synthesis and metabolism of ECM to alleviate the inflammation of joints and delay the onset and progression of OA. According to the clinical symptoms， OA can be classified into the category of impediment in traditional Chinese medicine. With the theories of holistic conception， treatment based on syndrome differentiation， and individualised diagnosis and treatment， traditional Chinese medicine has demonstrated definite effects in the treatment of OA in thousands of years of practice. Moreover， traditional Chinese medicine causes mild adverse reactions， and the patients have high tolerance and acceptance. This paper briefly explains the roles of autophagy and the related regulatory proteins， such as Unc-51-like autophagy-activated kinase 1 （ULK1）， Beclin-1， and microtubule-associated protein light chain 3 （LC3）， and details the latest research achievements in the prevention and control of OA by traditional Chinese medicines and its related markers via the regulation of autophagy， so as to provide a idea for the in-depth research in this field and the clinical application of traditional Chinese medicine in preventing and treating OA.

Exploration of Decision-Making Methods Based on Syndrome Differentiation by “Data-Knowledge” Dual-Driven Models： A Case Study of Gastric Precancerous State / 中医杂志

Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

Objective To investigate the difference between the management of patients in arrhythmia ward and non-arrhythmia wards and optimize the management plan of patients with atrial fibrillation.Methods Data of 1 537 patients with atrial fibrillation admitted to the arrhythmia ward and non-arrhythmia ward in the Department of Cardiology of the Second Hospital of Tianjin Medical University from September 2019 to September 2021 were collected.Baseline data,use of oral anticoagulants,use of heart rate control drugs and antiarrhythmic drugs,and use of antiplatelet drugs were compared between the two groups.Results The mean CHA2DS2-VASc score in the non-specialized atrial fibrillation(AF)management group was higher than that in the specialized AF management group,and the difference was statistically significant[(4.76±1.71)vs.(3.46±1.87),P＜0.001].There were statistically significant differences between the two groups in terms of gender,age,comorbidities such as heart failure,hypertension,diabetes,stroke,and vascular disease(all P＜0.001).The proportion of paroxysmal and permanent AF types in the non-specialized AF management group was higher(P＜0.001).The usage rates of rate control drugs(56.0％vs.40.1％),beta-blockers(50.7％vs.36.6％),and digoxin(17.6％vs.5.2％)were significantly higher in the non-specialized AF management group compared to the specialized AF management group,all with statistical significance(all P＜0.001).The usage rates of antiarrhythmic drugs(49.8％vs.22.6％),amiodarone(26.2％vs.5.6％),dronedarone(3.1％vs.0.4％),and propafenone(2.9％vs.0.1％)were significantly higher in the specialized AF management group compared to the non-specialized AF management group,all with statistical significance(all P＜0.001),while there was no statistical difference in the usage rate of sotalol between the two groups.The proportion of patients undergoing coronary artery examination in the non-specialized AF management group(43.6％)was significantly higher than that in the specialized AF management group(25.7％),with statistical significance(P＜0.001).Conclusions The treatment of patients with atrial fibrillation varies greatly due to the management of different specialized wards.

Association between the magnitude of systolic blood pressure reduction after successful endovascular thrombectomy with outcomes and post-procedure symptomatic intracranial hemorrhage in acute large vessel occlusion stroke patients / 中国脑血管病杂志

Objective To explore the association of the magnitude of systolic blood pressure reduction(SBPr)with post-procedure 24 h symptomatic intracranial hemorrhage(sICH)and 90-day clinical outcomes in patients with successful endovascular thrombectomy(EVT).Methods Consecutively registered patients with EVT caused by anterior circulation large vessel occlusion stroke(LVOS)in the First Affiliated Hospital of Wannan Medical College(Yijishan Hospital)between July 2015 and April 2023 and patients with successful reperfusion were analyzed.Demographic data,medical history(hypertension,diabetes),the trial of Org 10172 in acute stroke treatment(TOAST)classification,the baseline National Institutes of Health Stroke Scale(NIHSS)score and the baseline Alberta stroke early CT(ASPECT)score of patients were collected.And procedure related parameters(including time from onset to puncture,time from onset to reperfusion,occluded site[internal carotid artery,M1 segment of middle cerebral artery,M2 segment of middle cerebral artery],collateral circulation status[determined based on preoperative occluded angiography showing the range of collateral circulation in the occluded vessel area,defined as good collateral circulation with a reflux range of ≥ 50％and poor collateral circulation with a reflux range of＜50％]),immediate postoperative reperfusion status(evaluated using the modified thrombolysis for cerebral infarction[mTICI]grading,successful reperfusion defined as mTICI grading of 2b-3),24 hours sICH,and 90 days clinical outcomes(evaluated using the modified Rankin scale score at 90days after EVT,with a score ≤ 2indicating a good prognosis and a score＞2indicating a poor prognosis).SBPr was defined as(baseline SBP-mean SBP)/baseline SBP x 100％.According to the the magnitude of SBPr,SBPr is divided into 5 categories(＜-10％,-10％-10％,＞10％-20％,＞20％-30％and＞30％).Based on the clinical outcomes at 90 days and the occurrence of sICH at 24 hours after EVT,patients were divided into a good prognosis group and a poor prognosis group,as well as an sICH group and a non-sICH group.The relationship between SBPr and postoperative 90 days clinical prognosis or sICH was analyzed using a binary Logistic regression model.Subgroup analysis was conducted based on a history of hypertension(yes and no),continuous intravenous hypotensive therapy(yes and no),baseline ASPECT scores(3-5 and 6-10),and collateral circulation status(good and bad).Using a restricted cubic plot to depict the relationship between SBPr and sICH and clinical prognosis at 90days.Results(1)In total,731 patients were included.The median age was 71(62,77)years and 424(58.0％)were men.The median baseline NIHSS score was 14(12,18),the median baseline ASPECT was 9(7,10),405(55.4％)patients achieved 90-day modified Rankin scale score 0-2,and 35 patients(4.8％)developed sICH.(2)Multivariate analysis showed that the older age(OR,1.036,95％CI 1.017-1.056),the higher baseline NIHSS score(OR,1.095,95％CI1.049-1.144),the lower baseline ASPECT score(OR,0.704,95％CI 0.636-0.780),diabetes(OR,1.729,95％CI 1.084-2.758),bad collateral circulation(good collateral circulation vs.bad collateral circulation,OR,0.481,95％CI 0.332-0.696)and SBPr＞30％(SBPr-10％-10％as a reference,OR,2.238,95％CI 1.230-4.071),the higher the risk of poor clinical outcomes at 90 days(all P＜0.05).Continuous intravenous hypotensive therapy is a risk factor for postoperative 24 h sICH(OR,2.278,95％CI 1.047-4.953;P=0.038),while SBPr 20％-30％is associated with a lower risk of postoperative 24 h sICH(SBPr-10％-10％as a reference,OR,0.362,95％CI0.131-0.998;P=0.049).(3)The restrictive cube plot shows that there is a U-shaped relationship between SBPr after EVT and poor clinical outcomes at 90 days,while there is a nearly linear relationship with the occurrence of sICH.The more SBP reduction,the lower the incidence of sICH.(4)In the subgroup analyses,in the non-hypertension history and the good collateral circulation group,SBPr＞30％has a higher risk of poor clinical outcomes compared to SBPr-10％-10％(OR and 95％CI were 2.921[1.000-8.528]and 2.363[1.078-5.183],respectively,with P=0.05 or P＜0.05);After EVT,the group receiving continuous intravenous hypotensive therapy and the baseline ASPECT score 6-10 groups showed a significant correlation between SBPr＞30％and poor clinical outcomes at 90 days(SBPr-10％-10％as a reference,OR and 95％CI were 2.646[1.168-5.993]and 2.481[1.360-4.527],respectively,with P＜0.05).The correlation between SBPr and lower incidence of sICH was only found in the subgroup of poor collateral circulation(SBPr-10％-10％as a reference,SBPr＞20％-30％:OR,0.133,95％CI 0.027-0.652;SBPr＞30％:OR,0.104,95％CI 0.013-0.864;all P＜0.05).Conclusions Among patients who achieved successful reperfusion with EVT,SBPr might be related to a worse functional outcome at 90 days and sICH 24 h after operation.However,the relationship may exhibit significant heterogeneity across different subgroups.Baseline ASPECT score,history of hypertension,collateral circulation,and the use of continuous venous hypertension after EVT have been highlighted in individualized blood pressure management after EVT.

ObjectiveTo study the effect and mechanism of Xiangsha Liu Junzitang combined with phlegm-removing and detoxifying traditional Chinese medicine on immune escape in Lewis lung cancer mice. MethodA total of 60 specific-pathogen-free （SPF）-grade C57BL/6J male mice were injected subcutaneously with 0.2 mL of Lewis cell suspension （containing 2×106 cells·mL-1） in the right mid-axillary line. After 7 days， the mice that had been successfully modeled were randomly divided into six groups： the model group， the cisplatin group， the Xiangsha Liu Junzitang low-， medium-， and high-dose groups， and the combined group， with 10 mice in each group. The Xiangsha Liu Junzitang low-， medium- and high-dose groups were gavaged with 17.88， 35.75， 71.50 g·kg-1 Xiangsha Liu Junzitang solution once a day， respectively， and the dosage of cisplatin intraperitoneally injected into the mice was converted to 5 mg·kg-1 twice a week， and the tumour volumes of each group were measured every two days. The intervention lasted for 14 consecutive days. At the end of treatment， the tumour mass of mice in each group was weighed and the tumour inhibition rate was calculated. The morphological characteristics of tumours in each group were observed by hematoxylin-eosin （HE） staining. Fluorescent quantitative real-time polymerase chain reaction （Real-time PCR） assay was used to detect messenger ribonucleic acid （mRNA） contents of the natural killer group 2 member D （NKG2D） receptor， ribonucleic acid export-1 （RAE-1）， and γ interferon （IFN-γ） in the tumour tissues of each group. NKG2D， RAE-1， and IFN-γ mRNA in tumour tissues of each group. Immunohistochemistry （IHC） and Western blot were applied to detect the expressions of RAE-1， NKG2D， and IFN-γ in tumour tissues of each group， and Western blot was used to detect the expressions of interleukin-6 （IL-6）， Janus kinase 2 （JAK2）， p-JAK2， signal transducer and activator of transcription 3 （STAT3）， and p-STAT3 in tumour tissues of each group， as well as the protein levels of NKG2D， and RAE-1 in spleen tissues of each group. ResultCompared with that in the model group， the tumour mass decreased in all dose groups of Xiangsha Liu Junzitang， with no statistically significant difference. The tumour volume was reduced （P<0.05， P <0.01）. The pathological morphology was improved. The mRNA contents of NKG2D， RAE-1 and IFN-γ were increased in the medium-dose group （P<0.05， P<0.01）， and the protein expressions of NKG2D， RAE-1， and IFN-γ in tumour tissues were elevated （P<0.05， P<0.01）， and p-JAK2 and p-STAT3 protein expressions were decreased （P<0.05， P<0.01）. In spleen tissues， the protein expressions of NKG2D and RAE-1 in all dose groups of Xiangsha Liu Junzitang were significantly elevated （P<0.01）. Compared with those in the cisplatin group， NKG2D， RAE-1 and IFN-γ mRNA contents were elevated in the middle-dose group of Xiangsha Liu Junzitang， and the difference was not statistically significant. IHC showed that the protein expressions of NKG2D and IFN-γ in the combined group were significantly elevated （P<0.01）， and Western blot results showed that the protein expressions of RAE-1， NKG2D and IFN-γ were elevated （P<0.05， P<0.01）. p-JAK2 and p-STAT3 protein expressions were decreased in the combined group （P<0.05， P<0.01）. NKG2D and RAE-1 protein expressions were significantly increased in spleen tissues of the medium-dose groups and the combined group （P<0.01）. ConclusionXiangsha Liu Junzitang combined with phlegm-removing and detoxifying traditional Chinese medicine can inhibit the growth of tumours in Lewis lung cancer mice by up-regulating the expressions of RAE-1/NKG2D， promoting the activation of NK cells， and inhibiting immune escape， the mechanism of which may be related to down-regulation of the JAK2/STAT3 pathway.

Transcriptomic analysis of the molecular mechanism of Tiaopi Chengqi decoction improving gastric digestive function in mice with food accumulation / 中国临床药理学与治疗学

AIM:To explore the molecular mechanism of Tiaopi Chengqi decoction (TpCqD) improving hyperthermia and high-protein food-induced hyperphagia mice based on transcriptomics. METHODS:C57 mice were randomly divided into a control group, model group, low-dose TpCqD group, high-dose TpCqD group, and domperidone group. The general condition of the experimental mice was observed and the average food intake was counted, and the rate of gastric emptying and intestinal propulsion was determined for each group of mice. H&E staining was used to observe pathological changes in gastric tissue. PAS staining was used to observe glycogen changes in gastric tissue. Pepsin activity was determined by colorimetry. pH value of gastric contents was measured by acid-base titration. Transcriptome sequencing was used to analyze the differential genes in gastric tissue, a volcano map and a cluster heat map were made for the differential genes, and KEGG was used to analyze the signal pathway enrichment of the differential genes. RT-qPCR verified the differential genes obtained by screening. RESULTS:After treatment with TpCqD, the body weight and average food intake of mice with food accumulation increased (P<0.05), and the intestinal propulsion rate and gastric emptying speed of mice with food accumulation accelerated (P<0.05). TpCqD could protect gastric tissue structure and glycogen degradation, increase pepsin activity (P<0.05), and reduce gastric content pH (P<0.05). Transcriptome results showed that TpCqD could regulate the expression of Acox2 and cilp2, regulate fat digestion and absorption, protein digestion and absorption, and pancreatic secretion signals. RT-qPCR showed that compare with model group, TpCqD up-regulated Acox2 (P<0.05) and down-regulated the mRNA level of cilp2 (P<0.05).

Neonatal hyperbilirubinaemia, clinically presenting as jaundice, is a ubiquitous and commonly a benign metabolic condition in newborn infants.It is a leading cause of hospitalization of neonates in the first week of life.Serum bilirubin has been considered as the most potent superoxide with the peroxyl radical scavenger activity.However, uncontrolled hyperbilirubinaemia or rapidly rising bilirubin can reach a neurotoxic concentration, potentially leading to central nervous system sequelae.Thus, the health status of jaundiced newborn infants is dependent on striking an appropriate balance between the protective effects of serum bilirubin and the risk of bilirubin neurotoxicity.In order to standardize the management of neonatal hyperbilirubinemia (jaundice), many countries have developed clinical practice management guidelines.This review sorted out and briefly interpreted the main contents of clinical management guidelines for neonatal hyperbilirubinemia drafted by the American Academy of Pediatrics and other countries, aiming to provide references of clinical diagnosis and treatment practice to domestic pediatrician.

Evaluation and management of neonatal anemia and blood transfusion / 中国小儿急救医学

Anemia and blood transfusion are common clinical problems in newborns, especially premature infants.What are the definition and influencing factors of neonatal anemia? What is the difference between anemia in preterm infants and full-term infants? What are the changes of pathophysiology and their effects on tissues and cells during neonatal anemia? What are the prevention strategies and treatment methods of neonatal anemia? Is there a uniform hemoglobin threshold for neonatal transfusion of red blood cells? What are the risks of blood transfusion? In view of the above problems, this review proposed that the definition of anemia should consider the effects of gestational age, day age, intrauterine or postnatal development status(such as growth retardation), nutrition and so on. "Physiological anemia of infancy" can occur in healthy term infants; "anemia of prematurity" can not be considered as a physiologic and benign event, which is related to the low level of endogenous erythropoietin and iatrogenic blood loss.It is emphasized that neonatal anemia(especially premature infants) is preventable and can be prevented, and prevention is more important than treatment.Neonates lack a uniform hemoglobin threshold and are at risk of blood transfusion during red blood cell transfusion.

Research progress on the relationship between home food environment and overweight and obesity in children and adolescents / 中国学校卫生

Abstract@#The rate of overweight and obesity in Chinese children and adolescents is gradually increasing, and it has multiple hazards for their health. Overweight and obesity are affected by many factors such as genetics and environment. The home food environment is very important among the many factors affecting children s overweight and obesity. This paper analyzes the relationship between parents feeding behaviors, including pressure eating, restricted eating and food as reward, accessibility and usability of family food, with overweight and obesity of children and adolescents, aiming to provide a scientific reference for controlling children overweight and obesity by focusing on home food environment.

Comparison of visual function before and after wearing amber filter in low vision patients with primary retinitis pigmentosa / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the visual function of low-vision patients with primary retinal pigmentosa(RP)before and after wearing amber filter.METHODS: Self-control before and after study. A total of 30 patients(60 eyes)with low vision who were diagnosed with primary RP in the ophthalmology clinic of Xi'an No.1 Hospital from August 2021 to March 2022 were collected. The uncorrected distance visual acuity(UCDVA), best-corrected distance visual acuity(BCDVA), uncorrected near visual acuity(UCNVA), best-corrected near visual acuity(BCNVA), visual field and Farnsworth-Munsell(FM)-100 color visions were recorded before and after wearing amber filter. The contrast sensitivity(CS)in three visual environments including bright room, darkroom and darkroom with glare was measured and recorded respectively, and the changes of those parameters were analyzed before and after wearing filter.RESULTS: UCDVA and BCDVA after wearing the filter were better than those before wearing(t=-2.32, P&#x0026;#x003C;0.001; t=-6.77, P&#x0026;#x003C;0.001), while there was no statistically significant difference in UCNVA and BCNVA before and after wearing filter. The visual field index(VFI)after wearing filter was lower than that before wearing(t=8.62, P&#x0026;#x003C;0.001), and the mean defect(MD)of visual field was greater than that before wearing(t=7.73, P&#x0026;#x003C;0.001). FM100 color chess test showed that both total error score(TES)and partial error score(PES)in multiple regions were higher than those before wearing filter(P&#x0026;#x003C;0.001). After wearing, the CS of each frequency band in the environment of bright room and darkroom with glare was higher than that before wearing(P&#x0026;#x003C;0.001), and there was no statistically significant difference in each frequency band before and after wearing amber filter under the environment of darkroom without glare.CONCLUSION: Patients with low vision of primary RP showed improved UCDVA and BCDVA, but unchanged UCNVA and BCNVA after wearing amber filter, while the visual field and color discrimination were worse than those before wearing filter. The CS of the bright room and darkroom with glare environment was improved than before wearing filter, while there were no significant changes in CS under darkroom without glare.

Mechanism of Honghua Oral Liquid in Alleviating Neuropathic Pain / 中国实验方剂学杂志

ObjectiveTo investigate the pharmacodynamic characteristics and explore the molecular mechanism of Honghua oral liquid （HOL） in relieving neuropathic pain （NP）. MethodHealthy male SD rats were randomly assigned into sham group， model group， low-， medium-， high-dose （0.5， 1.0， 2.0 mL·kg-1·d-1， respectively） HOL groups， and a positive drug （pregabalin， 25 mg·kg-1·d-1） group， with 6 rats in each group. Spinal nerve ligation （SNL） of L5 was conducted in other groups except the sham group. Drug administration was performed 3 days after the SNL surgery for 2 consecutive weeks， and samples were collected after the end of the administration. During the treatment period， the mechanical pain threshold and cold pain threshold were determined to measure the pain-relieving effect of HOL. Transcriptome sequencing was performed on hippocampal tissue samples from the sham， model， and high-dose HOL groups， and differentially expressed genes between the sham group and the model group as well as the model group and HOL high-dose group were obtained. After pathway enrichment analysis， we selected the targets which were closely related to neuroinflammation for validation， and predicted the specific binding sites of the major active components in HOL with the targets through molecular docking. In addition， the serum levels of tumor necrosis factor-α （TNF-α） and interleukin-10 （IL-10） were determined by enzyme-linked immunosorbent assay （ELISA） to evaluate the effect of HOL on neuroinflammation in NP rats. ResultCompared with the sham group， SNL decreased the mechanical pain threshold and cold pain threshold （P<0.05）. Compared with the model group， HOL recovered the mechanical pain threshold and cold pain threshold （P<0.05）. The transcriptome data showed that 376 differentially expressed genes （DEGs） were identified between the model group and the sham group， including 124 upregulated genes and 252 downregulated genes， and 194 DEGs between the model group and the high-dose HOL group， including 33 upregulated genes and 161 downregulated genes. Among them， insulin-like growth factor 1（IGF1）， matrix metallopeptidase-2 （MMP-2）， matrix metallopeptidase-14 （MMP-14）， erb-B2 receptor tyrosine kinase 2 （ERBB2）， and integrin subunit alpha 5 （ITGA5） associated with NP were selected for further validation. The Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） results showed that compared with the sham group， the modeling up-gurelated the mRNA levels of the above five molecules in the hippocampus （P<0.01）. Compared with model group， HOL down-regulated the mRNA levels of these molecules （P<0.01）. The molecular docking results showed that the main active components of safflower， hydroxysafflor yellow A， kaempferol， and quercetin， formed stable hydrogen bonds with the amino acid residues of IGF1， MMP-2， MMP-14， ERBB2， and ITGA5. The enzyme-linked immunosorbent assay（ELISA） results showed that compared with those in the sham group， the serum levels of TNF-α and IL-10 were out of balance in the model rats （P<0.01）. Compared with the model group， HOL lowered the level of the pro-inflammatory cytokine TNF-α （P<0.01） and elevated that of the anti-inflammatory cytokine IL-10 （P<0.05）. ConclusionHOL exerts analgesic effect on SNL rats by inhibiting neuroinflammation.
