ABSTRACT

Danggui Sinitang is first recorded in the Treatise on Cold Damage written by ZHANG Zhongjing in the Han dynasty. It is composed of Angelicae Sinensis Radix, Cinnamomi Ramulus, Paeoniae Radix Alba, Asari Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, Tetrapanacis Medulla, and Jujubae Fructus and serves as a classic formula for treating the syndrome of blood deficiency and cold reversal. This study systematically reviews the records of Danggui Sinitang in ancient Chinese medicine books of various dynasties and the modern clinical applications to probe into the composition, plant species, processing, dosage, decocting method, and indications of Danggui Sinitang, aiming to provide a reference for the development and clinical application of this classic formula. The review of the records showed that there were a variety of records of Danggui Sinitang with different composition, and the composition of this formula listed in the Treatise on Cold Damage has a significant impact on later generations and has been used by medical practitioners throughout history. Although the dosage of some drugs decreased during the Ming and Qing dynasties, the medical practitioners continued to use the original formula. In terms of processing, although there were slight changes in the processing of Angelicae Sinensis Radix, Paeoniae Radix Alba, Glycyrrhizae Radix et Rhizoma, and Tetrapanacis Medulla, the original processing method was inherited. In terms of indications, Danggui Sinitang was designed to treat cold reversal due to blood deficiency and dysentery. Furthermore, it was used to treat headache, convulsive disease, infantile convulsion, and private part adduction in the Ming and Qing dynasties. Nowadays, this formula is mostly used to treat diabetes peripheral neuropathy, rheumatoid arthritis, dysmenorrhea, Raynaud's disease and other diseases. In terms of precautions, ancient physicians believed that Danggui Sinitang should not be taken by pregnant women and should only be used for limb chills caused by blood deficiency and cold coagulation. For limb chills caused by other reasons, this formula should not be used indiscriminately. Modern research has not reported any serious adverse reactions related to this formula. Danggui Sinitang has a definite therapeutic effect. In subsequent research and development, quality control standards of Danggui Sinitang should be established while its safety is ensured, and the related preparations should be developed and applied.

ABSTRACT

ObjectiveTo explore the correlation between skeletal muscle mass and metabolic syndrome (MS) disease risk among middle-aged and elderly community residents in Urumqi, and to provide a theoretical basis for understanding the relationship between skeletal muscle mass and MS among middle-aged and elderly community residents in China. MethodsA total of 1 438 community residents ≥ 50 years old were selected as the research subjects from July 2018 to January 2019 in Urumqi. They were selected from a multi-ethnic natural population cohort in Xinjiang. Data were collected through questionnaires, physical examination, bioelectrical impedance analysis (BIA), laboratory tests, etc. Skeletal muscle mass was evaluated using the limb skeletal muscle mass index (SMI) corrected for body weight; MS was defined as it at least includes three of the following: abdominal obesity, hypertension, hyperglycemia, high triglycerides and low high-density lipoprotein cholesterol. SMI was divided into four quantile arrays of Q1‒Q4. Trend χ2 test was applied to explore whether there was a correlation between SMI changes and MS. A multivariate logistic regression model was used to analyze whether there is a difference in the risk of MS between the higher SMI group (Q2, Q3, Q4) and the reference group Q1. ResultA total of 560 MS patients were detected in this study, with a prevalence rate of 38.94%. Among them, the prevalence rate of MS was 39.16% in males and 38.80% in females. The increase in male SMI grading level is not correlated with the prevalence of MS (trend P>0.05); After adjusting for confounding factors (model 4), the increase in SMI was still not related to the prevalence of MS (Ptrend=0.995). There was no statistical difference in the risk of MS between the lowest quartile group Q1 and the highest quartile group Q4 (OR=1.01, 95%CI: 0.69‒1.78). The prevalence of MS in women gradually decreased with the increase of SMI grading level (Ptrend<0.001); After adjusting for confounding factors (model 4), there was still a correlation between the increase of SMI and the prevalence of MS (Ptrend=0.005). With the lowest quartile of SMI Q1 as the reference group, the risk of MS in Q2 (OR=0.63, 95%CI: 0.40‒1.00), Q3 (OR=0.56, 95%CI: 0.34‒0.94), Q4 (OR=0.42, 95%CI: 0.23‒0.76) decreased. ConclusionAn increase in skeletal muscle mass may be beneficial for preventing MS, especially among middle-aged and elderly female residents. Considering the intensification of aging in China and the close relationship between MS and related comorbidities, managing skeletal muscle mass may contribute to potential MS prevention.

ABSTRACT

OBJECTIVE@#To analyze the clinical phenotype and genetic characteristics of a child with Hereditary spastic paraplegia (HSP).@*METHODS@#A child with HSP who was admitted to the Third Affiliated Hospital of Zhengzhou University on August 10, 2020 due to discovery of tiptoeing for 2 years was selected as the study subject, and relevant clinical data was collected. Peripheral blood samples of the child and her parents were collected for the extraction of genomic DNA. And trio-whole exome sequencing (trio-WES) was carried out. Candidate variants were verified by Sanger sequencing. Bioinformatic software was used to analyze the conservation of variant sites.@*RESULTS@#The child was a 2-year-and-10-month-old female with clinical manifestations including increased muscle tone of lower limbs, pointed feet, and cognitive language delay. Trio-WES results showed that she had harbored compound heterozygous variants of c.865C>T (p.Gln289*) and c.1126G>A (p.Glu376Lys) of the CYP2U1 gene. And the corresponding amino acid for c.1126G>A (p.Glu376Lys) is highly conserved among various species. Based on guidelines from the American College of Medical Genetics and Genomics, the c.865C>T was predicted as a pathogenic variant (PVS1+PM2_Supporting), and c.1126G>A was rated as a variant of uncertain significance (PM2_Supporting+PM3+PP3).@*CONCLUSION@#The child was diagnosed with HSP type 56 due to compound variants of the CYP2U1 gene. Above findings have enriched the mutation spectrum of the CYP2U1 gene.

ABSTRACT

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%.

ABSTRACT

OBJECTIVE@#To improve the understanding of the virome and bacterial microbiome in the wildlife rescue station of Poyang Lake, China.@*METHODS@#Ten smear samples were collected in March 2019. Metagenomic sequencing was performed to delineate bacterial and viral diversity. Taxonomic analysis was performed using the Kraken2 and Bracken methods. A maximum-likelihood tree was constructed based on the RNA-dependent RNA polymerase (RdRp) region of picornavirus.@*RESULTS@#We identified 363 bacterial and 6 viral families. A significant difference in microbial and viral abundance was found between samples S01-S09 and S10. In S01-S09, members of Flavobacteriia and Gammaproteobacteria were the most prevalent, while in S10, the most prevalent bacteria class was Actinomycetia. Among S01-S09, members of Myoviridae and Herelleviridae were the most prevalent, while the dominant virus family of S10 was Picornaviridae. The full genome of the pigeon mesivirus-like virus (NC-BM-233) was recovered from S10 and contained an open reading frame of 8,124 nt. It showed the best hit to the pigeon mesivirus 2 polyprotein, with 84.10% amino acid identity. Phylogenetic analysis showed that RdRp clustered into Megrivirus B.@*CONCLUSION@#This study provides an initial assessment of the bacteria and viruses in the cage-smeared samples, broadens our knowledge of viral and bacterial diversity, and is a way to discover potential pathogens in wild birds.

ABSTRACT

Idiopathic pulmonary fibrosis (IPF) is a chronic progressive lung disease characterized by progressive lung fibrogenesis and histological features of usual interstitial pneumonia. IPF has a poor prognosis and presents a spectrum of disease courses ranging from slow evolving disease to rapid deterioration; thus, a differential diagnosis remains challenging. Several biomarkers have been identified to achieve a differential diagnosis; however, comprehensive reviews are lacking. This review summarizes over 100 biomarkers which can be divided into six categories according to their functions: differentially expressed biomarkers in the IPF compared to healthy controls; biomarkers distinguishing IPF from other types of interstitial lung disease; biomarkers differentiating acute exacerbation of IPF from stable disease; biomarkers predicting disease progression; biomarkers related to disease severity; and biomarkers related to treatment. Specimen used for the diagnosis of IPF included serum, bronchoalveolar lavage fluid, lung tissue, and sputum. IPF-specific biomarkers are of great clinical value for the differential diagnosis of IPF. Currently, the physiological measurements used to evaluate the occurrence of acute exacerbation, disease progression, and disease severity have limitations. Combining physiological measurements with biomarkers may increase the accuracy and sensitivity of diagnosis and disease evaluation of IPF. Most biomarkers described in this review are not routinely used in clinical practice. Future large-scale multicenter studies are required to design and validate suitable biomarker panels that have diagnostic utility for IPF.

ABSTRACT

Objective:To evaluate the clinical efficacy of modified all-arthroscopic reconstruction of medial patella femoral ligament (MPFL) for the treatment of recurrent patellar dislocation.Methods:A retrospective case series study was conducted to analyze the clinical data of 38 patients (46 knees) with recurrent patellar dislocation, who were treated at First Affiliated Hospital of Shenzhen University from January 2017 to January 2020. The patients included 12 males (12 knees) and 26 females (34 knees), aged 14-40 years [(24.6±5.4)years]. All patients underwent the modified all-arthroscopic MPFL reconstruction procedure. The femoral tunnel locations were assessed by 3D-CT immediately after surgery. The MRI was performed at 6 and 12 months after operation to assess the healing morphology of the reconstructed MPFL. The Lysholm score and Kujala score were used to assess the knee function before operation, at 6 months after operation, at 12 months after operation and at the last follow-up. The time to return to sports as well as complications were observed.Results:All patients were followed up for 26-48 months [(32.4±8.6)months]. Postoperative 3D-CT examination showed that the femoral tunnels were located in the groove area of the medial epicondyle of the femur and the adductor tubercle. At 6 and 12 months after operation, MRI T2 images showed that the reconstructed MPFL had a low signal and well tensioned ligament tissue, indicating that the MPFL was healed well. The Lysholm scores at 6 and 12 months postoperatively and at the last follow-up were (81.1±12.0)points, (91.2±3.8)points, and (92.2±9.8)points, respectively, being significantly higher than the preoperative (52.4±10.6)points (all P<0.01). The Kujala scores at 6 and 12 months postoperatively and at the last follow-up were (85.4±3.9)points, (91.4±3.6)points, and (93.1±8.5)points, respectively, being significantly higher than the preoperative (55.2±6.8)points (all P<0.01). Compared with 6 months postoperatively, the Lysholm score and Kujala score were significantly improved at 12 months postoperatively and at the last follow-up (all P<0.05). All patients returned to sports, with the time to return to sports for 3-12 months [(8.7±2.3)months] after operation. One patient had poor wound healing but was healed after dressing changes. No wound infection, nerve injury, joint stiffness, patella re-dislocation or other complications occurred. Conclusion:For recurrent patellar dislocation, the modified all-arthroscopic MPFL reconstruction has advantages of accurate bone tunnel positioning, good ligament healing, good function recovery, early return to sports, and less postoperative complications.

ABSTRACT

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

ABSTRACT

Objective:To assess the early physical growth and development of human immunodeficiency virus-exposed uninfected (HEU) children by longitudinally comparing the differences of growth and development between HEU group and the healthy human immunodeficiency virus-unexposed uninfected (HUU) control group of children aged 0 to 18 months.Methods:A retrospective cohort study was designed.Maternal information of the human immunodeficiency virus (HIV) infected mothers and follow-up information at 0, 1, 3, 6, 9, 12, and 18 months postpartum of their children (born between January 2013 and December 2019 in Chengdu City) were collected from the Information System of Prevention of Mother-to-Child Transmission of Human Immunodeficiency Virus Management. The HUU control group was matched with HEU group by maternal age, gestational age at birth, and infant gender at a ratio of 1∶1. There were 385 children each included in the HEU and HUU groups. Matched samples t-test and the multilevel models were used to compared the physical developmental differences between the two groups. Results:Weight for age Z scores (WAZ) at 0, 3, 6 months of HEU group were -0.72±1.03, -0.09±1.18 and 0.05±1.09, respectively, which were all lower than WAZ of HUU group (-0.21±1.04, 0.42±1.19 and 0.41±1.16, respectively), which were all significantly different ( t=8.41, 7.47 and 5.18, respectively, all P<0.001). Length for age Z scores (LAZ) at 3, 6, 12, 18 months of HEU group were -0.23±1.36, -0.01±1.48, -0.18±1.20 and -0.32±1.13, respectively, which were all lower than LAZ of HUU group (0.24±1.26, 0.30±1.26, 0.07±1.11 and 0.04±1.05, respectively), which were all significantly different ( t=6.14, 4.04, 2.72 and 4.30, respectively, all P<0.01). Weight for length Z scores (WLZ) at 0, 3, 6 months of HEU group were -1.05±1.18, 0.23±1.03 and 0.22±0.95, respectively, which were all lower than WLZ of HUU group (-0.20±0.98, 0.44±1.03 and 0.45±1.00, respectively), which were all significantly different ( t=10.90, 2.95 and 2.96, respectively, all P<0.01). After possible confounding factors were corrected, the WAZ of HEU children at 0, 3, 6 months were still lower than those of HUU children, the LAZ of 3, 6, 12, 18 months were still lower than those of HUU children, and the WLZ of 0, 3, 6 months were still lower than those of HUU children. Conclusions:The differences between HEU and HUU children in Chengdu City mainly occur within six months of age, but the differences of body length persist until 18 months of age.Prenatal exposure to HIV infection affects both fetal and postnatal body growth and development.

ABSTRACT

Objective:To explore the relationship between serum albumin (ALB), erythrocyte sedimentation rate (ESR), platelet/lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR) and coronary artery disease in children with Kawasaki disease (KD).Methods:120 KD children diagnosed in the Affiliated Hospital of Jining Medical College from December 2016 to November 2021 were selected as the research objects. They were divided into observation group (KD with coronary artery disease) and control group (KD with coronary artery disease) according to whether they had coronary artery disease, with 60 cases in each group; the serum ALB, ESR, PLR, NLR values of the two groups of children were compared. Receiver operating characteristic (ROC) curve was used to analyze the value of the above indicators in diagnosing KD children with coronary artery disease. The serum ALB, ESR, PLR, NLR levels of KD children with different degrees of coronary artery disease were analyzed.Results:The main manifestations of coronary artery disease in 60 children with KD combined with coronary artery disease were left main coronary artery and left anterior descending branch widening [56.67%(34/60)], left main coronary artery and left anterior descending branch widening [20.00%(12/60)], left anterior descending branch widening [16.67%(10/60)], left main coronary artery widening [11.67%(7/60)]. The serum ALB in the observation group was significantly lower than that in the control group ( P<0.05), and ESR was significantly higher than that in the control group ( P<0.05). There was no significant difference in serum PLR and NLR between observation group and control group (all P>0.05). The sensitivity, specificity and area under curve (AUC) value of serum ALB in diagnosing coronary artery disease in KD children were 73.61%, 78.42% and 0.813 respectively; The sensitivity, specificity and AUC of ESR in diagnosing coronary artery disease in KD children were 88.36%, 83.14% and 0.892 respectively; The sensitivity, specificity and AUC value of ESR combined with ALB in diagnosing coronary artery disease in KD children were 90.67%, 97.54% and 0.953 respectively. Among 60 children with KD complicated with coronary artery disease, 39 were diagnosed as coronary artery dilatation and 21 had coronary artery aneurysm. The serum ALB of children in the coronary artery aneurysm group was significantly lower than that in the coronary artery dilatation group ( P<0.05), and ESR was significantly higher than that in the coronary artery dilatation group ( P<0.05). There was no significant difference in PLR and NLR between the coronary artery aneurysm group and the coronary artery dilatation group (all P>0.05). Conclusions:Children with KD and coronary artery disease have lower serum ALB levels and higher ESR level. The above two indicators are of great value for the diagnosis of children with KD and coronary artery disease.

ABSTRACT

Objective:To investigate the effect of Liangxue Huoxue decoction on intestinal flora, intestinal barrier and NOD-like receptor protein 3 (NLRP3)/caspase-1/gasdermin D (GSDMD) pyroptosis signaling pathway in mice model of sepsis-induced acute kidney injury (AKI).Methods:The model of AKI was established by cecal ligation and perforation (CLP). Thirty male C57BL/6 mice were randomly divided into sham operation group (Sham group), sepsis group (CLP group) and sepsis+Liangxue Huoxue decoction (CLP+LXHX group), with 10 mice in each group. Mice in Sham group only underwent laparotomy. Two hours before model establishment, mice in CLP+LXHX group were treated with Liangxue Huoxue decoction (6 g/kg) by gavage; mice in Sham group and CLP group were given equal volume of normal saline by gavages. After 24 hours of modeling, all mice were sacrificed under anesthesia, and the colon and kidney tissues and fresh feces in the colon were taken. The pathological changes of kidney and colon were observed by hematoxylin-eosin (HE) staining under light microscope. Real-time polymerase chain reaction (RT-PCR) was used to detect inflammatory factors (interleukins, IL-1β and IL-18) in renal tissue. The expressions of NLRP3, caspase-1 and GSDMD were detected by Western blotting. The changes of intestinal flora in mice were detected by 16S rDNA high-throughput sequencing.Results:Compared with the Sham group, the inflammatory cell infiltration of the kidney tissue was increased and the kidney became vacuolated in CLP group, the mRNA expressions of IL-1β, IL-18, and the protein expressions of NLRP3, caspase-1 and GSDMD were significantly increased in CLP group, the species richness of intestinal microflora decreased significantly, the relative abundance of Enterococcus and Escherichia-Shigella increased significantly, and the relative abundance of Ileibacterium, Alloprevotella, Lachnospiraceae, Klebsiella and Parasutterella increased significantly in CLP group. Compared with CLP group, Liangxue Huoxue decoction can significantly reduce the pathological changes of kidney and colon tissue, reduce the pathological score (1.75±0.43 vs. 3.50±0.50 for kidney tissue, 1.25±0.43 vs. 4.50±0.50 for colon tissue, both P < 0.05), improve the composition of intestinal flora, reduce the relative abundance of Enterococcus and Escherichia-Shigella, and significantly increase the relative abundance of Lactobacillus and Akkermansia. In addition, Liangxue Huoxue decoction can significantly reduce mRNA expressions of IL-1β and IL-18 in kidney tissue [IL-1β mRNA (2 -ΔΔCt): 1.59±0.05 vs. 4.61±0.88, IL-18 mRNA (2 -ΔΔCt): 1.69±0.17 vs. 2.86±0.63, both P < 0.05] and the protein expressions of NLRP3, caspase-1 and GSDMD (NLRP3/GAPDH: 0.71±0.04 vs. 0.89±0.01, caspase-1/GAPDH: 1.04±0.04 vs. 1.48±0.04, GSDMD/GAPDH: 0.90±0.01 vs. 1.41±0.02, all P < 0.05). Conclusions:Liangxue Huoxue decoction has obvious protective effect on AKI induced by sepsis. It can improve intestinal barrier by regulating intestinal flora, thereby inhibiting the activation of NLRP3/caspase-1/GSDMD signaling pathway in kidney tissue and reducing the expression of proptosis-related inflammatory factors.

ABSTRACT

Objective:To investigate the mediating effect of rumination in primiparae on the expectation gap of social support and postpartum depression, so as to provide a reference basis for early detection and intervention in the regulation of meternal postpartum depression.Methods:In this cross-sectional study, questionnaires were administered from November 2021 to March 2022 using the general information questionnaire, the Ruminant Thinking Response Scale, the Postpartum Social Support Scale, and the Edinburgh Postpartum Depression Scale to 266 primiparae at three tertiary level A hospitals, the First Affiliated Hospital of Xi′an Jiaotong University, the Second Affiliated Hospital of Xi′an Jiaotong University, and the Northwest Women′s and Children′s Hospital, for postpartum review, and the relationship between ruminant thinking, social support expectation gap, and postpartum depression was analyzed using correlation analysis, structural equation modeling, and application of Bootsrap method.Results:The social support expectation gap, ruminative thinking, and postpartum depression average scores were (16.74 ± 12.77), (39.43 ± 4.14), (6.77 ± 2.77) points, respectively.There were positive correlations between social support expectation gap and ruminative thinking, postpartum depression, and ruminative thinking and postpartum depression ( r=0.62, 0.75, 0.70, all P<0.01). Primiparae ruminative thinking partially mediated the relationship between social support expectation gap and postpartum depression, with the mediating effect accounting for 22% of the total effect. Conclusions:Social support expectation gap can directly affect the occurrence of postpartum depression, but also indirectly through ruminative thinking, and postpartum depression can be prevented and intervened from the perspective of reducing ruminative thinking in clinical practice.

ABSTRACT

ObjectiveTo obtain the prevalence of sarcopenia in middle-aged and elderly people in Urumqi based on the 2020 updated based on the 2020 updated Consensus Report 2019 of Asian Working Group for Sarcopenia (AWGS2019), and to further explore the association between sarcopenia and metabolic syndrome (MS). MethodsA total of 1 438 middle-aged and elderly people (aged≥50 years) in Urumqi from July 2018 to January 2019 were selected as the research subjects. Data were collected by questionnaire survey, physical examination and laboratory test. Skeletal muscle mass,grip strength and 4 m walking speed were used to represent muscle mass, muscle strength and body function, respectively. Bioelectrical impedance analysis (BIA) was used to measure human body components. Based on the diagnostic criteria of sarcopenia recommended by AWGS2019, the prevalence of sarcopenia in people over 50 years old was obtained. Multivariate logistic regression model was used to explore the correlation between sarcopenia and MS in middle-aged and elderly people of different genders. ResultsThere were 194 patients with sarcopenia, with a prevalence of 13.49%. The prevalence was 15.56% in males and 12.12% in females. There was no significant difference in the prevalence of MS between male sarcopenia group (40.45%) and non-sarcopenia group (38.92%), while the prevalence of MS in female sarcopenia group (39.04%) was higher than that in non-sarcopenia group (27.56%). Multivariate logistic regression analysis showed that sarcopenia was a related factor of MS. Compared with non-sarcopenia, the risk of MS in male sarcopenia group was higher (OR=2.11,95%CI: 1.15‒3.88 ). ConclusionSarcopenia increases the risk of MS in middle-aged and elderly people, with a greater risk in men. Fully understanding of sarcopenia is helpful to early identify high-risk groups of MS and prevent the occurrence of MS.

ABSTRACT

The diagnosis and treatment of chronic refractory wounds on body surface has always been full of challenges, and it also poses a huge burden on medical care and society. High-throughput sequencing combined with omics analysis can reveal potential mechanisms of chronic wound formation, and identify potential biomarkers related to diagnosis, prognosis, and screening of chronic wound. Combined with multiple levels of omics analysis, the detailed molecular mechanism of chronic wound development can be further explored and understood, so as to provide clues for the formulation of personalized treatment methods and lay a solid foundation for the precision medicine of chronic wounds. Therefore, this review addresses the recent progress of various omics analyses in chronic refractory wounds on body surface.

ABSTRACT

OBJECTIVE@#To investigate the changes and roles of reactive oxygen species (ROS) and nuclear factor erythroid 2-related factor 2 (Nrf2) related antioxidases during erythroid development.@*METHODS@#Flow cytometry was used to detect the sensibility of peripheral red blood cells of wild-type mice to a strong oxidant hydrogen peroxide (H2O2). Erythroid cells from different developmental stages in bone marrow (BM) were obtained using fluorescence-activated cell sorter and the ROS levels were detected by flow cytometry. RT-qPCR was used to detect the changes of expression levels of Nrf2 and related antioxidases in erythroid cells from different developmental stages in BM. The ROS levels of the peripheral blood and BM nucleated erythrocytes in Nrf2 knockout mice were further examined. The expression level of Nrf2 in erythroid precursors isolated from 14.5 d embryonic liver of wild-type mice during differentiation and culture in vitro was detected.@*RESULTS@#In the peripheral blood of wild-type mice, the ROS level of reticulocytes and mature erythrocytes treated with H2O2 increased about 4 times and 7 times, respectively (P<0.01). In BM erythrocytes, the ROS level gradually decreased as the cells matured (r=0.85), while the expression level of Nrf2 and its related anti-oxidative genes increased (r=0.99). The ROS levels in peripheral blood erythrocytes and BM nucleated erythrocytes of Nrf2 knockout mice were significantly increased compared with wild-type mice (P<0.01). The expression of Nrf2 increased during the early erythroid development after embryonic liver cell sorting (P<0.01).@*CONCLUSION@#The expression levels of Nrf2 and its related factors vary during erythropoiesis. Nrf2 at physiological level plays an important antioxidant role during the erythroid development.

ABSTRACT

UPLC-Q-Exactive-MS/MS and network pharmacology were employed to preliminarily study the active components and mechanism of Jinwugutong Capsules in the treatment of osteoporosis. Firstly, UPLC-Q-Exactive-MS/MS was employed to characterize the chemical components of Jinwugutong Capsules, and network pharmacology was employed to establish the "drug-component-target-pathway-disease" network. The key targets and main active components were thus obtained. Secondly, AutoDock was used for the molecular docking between the main active components and key targets. Finally, the animal model of osteoporosis was established, and the effect of Jinwugutong Capsules on the expression of key targets including RAC-alpha serine/threonine-protein kinase(AKT1), albumin(ALB), and tumor necrosis factor-alpha(TNF-α) was determined by enzyme-linked immunosorbent assay(ELISA). A total of 59 chemical components were identified from Jinwugutong Capsules, among which coryfolin, 8-prenylnaringenin, demethoxycurcumin, isobavachin, and genistein may be the main active components of Jinwugutong Capsules in treating osteoporosis. The topological analysis of the protein-protein interaction(PPI) network revealed 10 core targets such as AKT1, ALB, catenin beta 1(CTNNB1), TNF, and epidermal growth factor receptor(EGFR). The Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment showed that Jinwugutong Capsules mainly exerted the therapeutic effect by regulating the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT) signaling pathway, neuroactive ligand-receptor interaction, mitogen-activated protein kinase(MAPK) signaling pathway, Rap1 signaling pathway and so on. Molecular docking showed that the main active components of Jinwugutong Capsules well bound to the key targets. ELISA results showed that Jinwugutong Capsules down-regulated the protein levels of AKT1 and TNF-α and up-regulated the protein level of ALB, which preliminarily verified the reliability of network pharmacology. This study indicates that Jinwugutong Capsules may play a role in the treatment of osteoporosis through multiple components, targets, and pathways, which can provide reference for the further research.

ABSTRACT

Noise is one of the most common environmental hazards to which people are exposed,and the exposure to noise can cause not only hearing but also non-hearing damage.Although noise under safety limits may not affect the auditory system,it can cause changes in stress hormone levels,which is harmful to health.However,the current studies about the impact of noise on health mainly focus on the auditory system,and little is known about the relationship between noise and stress hormone levels.Therefore,this paper reviews the studies involving noise exposure and stress hormone levels,aiming to provide ideas for strengthening the prevention and control of noise hazards.

ABSTRACT

During interventional procedures,subjects are exposed to direct and scattered X-rays.Establishing diagnostic reference levels is an ideal way to optimize the radiation dose and reduce radiation hazard.In recent years,diagnostic reference levels in interventional radiology have been established in different countries.However,because of the too many indicators for characterizing the radiation dose,the indicators used to establish diagnostic reference levels vary in different countries.The research achievements in this field remain to be reviewed.We carried out a retrospective analysis of the definition,establishment method,application,and main factors influencing the dose difference of the diagnostic reference level,aiming to provide a basis for establishing the diagnostic reference level for interventional procedures in China.

ABSTRACT

【Objective】 To investigate the effects of the loss of exon 1 of TFE3 on nuclear localization of chimeric TFE3 protein in TFE3 translocation renal cell carcinoma (TFE3 tRCC). 【Methods】 The localization of TFE3 protein in TFE3 tRCC and clear cell renal cell carcinoma (ccRCC) were detected with immunochemistry. The exon retention of TFE3 gene in TFE3 tRCC was analyzed in databases and literatures. The plasmids containing TFE3 full-length and different-length of TFE3 exons which were constructed to pCDH-MCS-EGFP-Puro were transfected into HEK293T using Lipo FiterTM. The localization of EGFP protein in HEK293T cells were detected with confocal microscopy. The localization of TFE3 protein and truncated TFE3 protein were detected with Western blotting. The mRNA expression of the downstream genes of TFE3 protein were detected with q-PCR. 【Results】 Strong nuclear signal of TFE3 protein was observed in TFE3 tRCC, whereas TFE3 protein in ccRCC was mainly localized in cytoplasm. The results of fluorescence imaging and Western blotting showed that TFE3 full-length protein was expressed both in nucleus and cytoplasm, and the expression of truncated TFE3 protein was mainly localized in nucleus. The q-PCR analysis demonstrated that the deletion of exon 1 in TFE3 gene led to a higher transcriptional level of targeted genes of TFE3 protein. 【Conclusion】 The loss of exon 1 in TFE3 played a critical role in preventing TFE3 protein from entering the nucleus. In TFE3 tRCC, the loss of exon 1 in TFE3 gene leads to the nuclear localization of TFE3 fusion protein and activation of its downstream target genes. This mechanism promises to uncover the occurrence and development of TFE3 tRCC.
