OBJECTIVE To monitor the common pathogens for viral diarrhea in children under 5 years old in Wuxi area,and to analyze their epidemiological characteristics and trends.METHODS Diarrhea specimens were collected from inpatient and outpatient children with diarrhea in sentinel hospitals in Wuxi from 2018 to 2023.The norovir-us,rotavirus,sapovirus,enteradenovirus and astrovirus were detected by Real-time fluorescence quantitative pol-ymerase chain reaction(PCR),and the monitoring results were statistically analyzed.RESULTS A total of 654 vi-rus-positive cases were detected from 1898 diarrhea specimens with an overall detection rate of 34.46%.Among them,norovirus and rotavirus had the highest detection rates 12.54%and 11.70%,respectively.The detection rate of viruses was the highest in children aged 12 to<24 months,reaching 59.03%.In inpatient children with di-arrhea,rotavirus had the highest detection rate at 14.03%,while in outpatient children with diarrhea,norovirus had the highest detection rate at 11.93%.There was a significant difference in the detection rate of rotavirus be-tween inpatient and outpatient children(P<0.05).CONCLUSION Viral diarrheal diseases exhibit a notably high detection rate among children aged 12 to<24 months in Wuxi,suggesting the need to further optimize prevention and control measures for this age group.

Objective:It aims to explore the advantages,disadvantages,opportunities and challenges of Chinese medicine practitioners participating in the"three-division co-management"service model in diabetes management,analyze its performance in policy support,resource matching and patient satisfaction,and put forward optimization strategies to enhance the role of Chinese medicine practitioners in chronic disease management.Methods:Through literature analysis,questionnaire survey and semi-structured interview,the data of six pilot units of"three divisions co-management"in Jinjiang were collected,and the internal and external environment of Chinese medicine practitioners participating in the"three divisions co-management"model was systematically evaluated by the Strengths,Weaknesses,Opportunities,Threats(SWOT)and the Politics,Economic,Society,Technology(PEST).Results:Chinese medicine practitioners' participation in the"three-division co-management"model has obvious advantages in policy support,resource matching and patient satisfaction,but it also faces key obstacles such as lack of incentive mechanism,shortage of Chinese medicine practitioners' resources and limitation of medical insurance reimbursement.The survey shows that 99.7％of the respondents are willing to choose this mode again,and 96.43％of the respondents said that the medical experience has improved significantly.However,43.92％of the subjects think that the professional knowledge and skills of doctors need to be improved,and 32.2％of the subjects think that the effect of Chinese medicine treatment on reducing the dependence and side effects of western medicine is limited.Conclusion:It is feasible and practical for Chinese medicine practitioners to participate in the"three divisions co-management"model,but it is necessary to further improve its service effect and sustainability by improving the performance appraisal mechanism,expanding the scope of medical insurance reimbursement,and strengthening the training for Chinese medicine practitioners' resources.

Objective: To investigate the potential efficacy and safety of Lutai Danshen Baishao granules (LDBG) for treating female melasma associated with kidney deficiency and blood stasis patterns. Methods: A randomized, double-blind, placebo-controlled trial was conducted at the Third Central Hospital of Tianjin, China from March to December 2023. A total of 110 female patients with melasma linked to kidney deficiency and blood stasis were enrolled and treated with either LDBG or a placebo twice daily for 60 days. Efficacy was assessed through measures such as the total melasma area, reduced melasma area, reduction rate of melasma area, melasma color score, Melasma Area and Severity Index (MASI) score, and traditional Chinese medicine (TCM) symptom score scale. Safety assessments included routine blood and biochemical tests. Results: Participants in both groups were aged 52–63 years, with no significant differences. After the 2-month intervention, the total melasma area decreased in both groups; however, a greater reduction was observed in the test group [462.50 mm2 (12.81%) vs. 100.00 mm2 (3.11%), P < .001]. Moreover, LDBG treatment significantly reduced the MASI and melasma color scores in the test group (P < .05). The total TCM symptom evaluation score significantly decreased (test group: 6.00 vs. placebo group: 7.00, P = .001), with significant relief in symptoms such as improvement in dark lips, nails, and waist soreness in the test group, compared with that in the placebo group (P < .05). Within-group comparisons revealed that TCM syndrome was significantly alleviated in the test group (P < .05). Conclusion LDBG intervention shows promising effectiveness in reducing female melasma and alleviating TCM syndromes.

Objective To study the relationship of serum 25-hydroxyvitamin D3[25-(OH)D3],myostatin(MSTN),limb skeletal muscle index(ASMI)with osteopenia(OP)in patients with rheumatoid arthritis(RA)complicated with sarcopenia(SA).Methods A total of 244 RA patients selected as case group,and 123 healthy people who underwent physical examination in our hospital during the same period were selected as control group.The general data,serum levels of 25-(OH)D3,MSTN,ASMI and peripheral blood immune cells were compared among the two groups.The diagnostic value of serum 25-(OH)D3,MSTN and ASMI in RA patients with SA complicated with OP and the correlation between serum 25-(OH)D3,MSTN,ASMI and peripheral blood immune cells were analyzed.Results The levels of serum 25-(OH)D3,peripheral blood regulatory T lymphocyte(Treg)cells and ASMI in the case group were lower than those in the control group,while the levels of serum MSTN,peripheral blood helper T lymphocyte 17(Th17)cells and Th17/Treg were higher than those in the control group(P＜0.05).Among the 244 RA patients,171 had no SA,73 had SA,and the incidence of SA was 29.92％.The levels of serum 25-(OH)D3,peripheral blood Treg cells and ASMI in the SA group were lower than those in the non-SA group,and the levels of serum MSTN,peripheral blood Th17 cells and Th17/Treg were higher than those in the non-SA group(P＜0.05).The levels of serum 25-(OH)D3,peripheral blood Treg cells and ASMI in the OP group were lower than those in the non-OP group,while the levels of serum MSTN,peripheral blood Th17 cells and Th17/Treg were higher than those in the non-OP group(P＜0.05).The area under the curve(AUC)of combined detection of serum 25-(OH)D3,MSTN and ASMI for the diagnosis of OP in RA patients with SA was higher than that of the three alone(P＜0.05).Serum 25-(OH)D3 and ASMI in RA patients with SA complicated with or without OP were negatively correlated with peripheral blood Th17 cell level and Th17/Treg(P＜0.05),and positively correlated with peripheral blood Treg cell level(P＜0.05).The level of serum MSTN was positively correlated with the level of Th17 cells and Th17/Treg in peripheral blood(P＜0.05),and negatively correlated with the level of Treg cells in peripheral blood(P＜0.05).Conclusion The incidence of OP in RA patients with SA is high.At the same time,the occurrence of SA and OP can lead to the decrease of serum 25-(OH)D3,peripheral blood Th17 cell,Th17/Treg and ASMI,and the increase of serum MSTN and peripheral blood Treg cell.The combination detection of 25-(OH)D3,MSTN and ASMI can effectively improve the diagnosis of OP in RA patients with SA,and the levels of the three are significantly correlated with peripheral blood Th17 cells,Treg cells and Th17/Treg.

Objective Human facial morphology is an appearance phenotype with high heritability,high diversity,and complexity.Traditional facial morphological genetic analysis is mostly based on facial landmark measurements,using linear regression for genome-wide association studies,but this method extracts limited facial morphological feature information.This study established an extraction method for multidimensional facial representations and validated the correlation between 473 single-nucleotide polymorphisms(SNPs)previously reported to be significantly associated with facial features and facial representations in the Han Chinese population.Methods After acquiring facial 3D images,3D morphable face models and HR-net network were used to align and quantify the 3D images,obtaining high-density 3D facial point cloud data.After unsupervised clustering of the point cloud,principal component analysis was applied to reduce dimensionality and extract multidimensional morphological phenotypes for each facial region.Based on these multidimensional phenotypes,partial least squares regression(PLSR)and canonical correlation analysis(CCA)were used for genetic association analysis.Results A total of 10 SNPs were validated to be significantly associated with facial morphology in Han Chinese,of which 7 SNPs were validated by the PLSR method,2 SNPs were validated by the CCA method,and 1 SNP was validated by both methods.Conclusion Among the 10 significantly associated SNP sites,9 related facial morphological regions were consistent with previous reports in other populations,indicating that genes affecting complex facial morphology have cross-population effects.
