Objective To systematically evaluate the effects of liraglutide combined with metformin on glucose and lipid metabolism,sex hormones,reproductive function,and gastrointestinal reactions in patients with polycystic ovary syndrome(PCOS).Methods We searched databases such as PubMed,WanFang Medical Network,WanFang Database,China National Knowledge Infrastructure(CNKI),and VIP Journals to collect randomized controlled trials published from January 2011 to August 2022 on the treatment of polycystic ovary syndrome with liraglutide combined with metformin,using Revman 5.4 for the meta-analysis.Results A total of 16 case-control studies were included,involving 1436 patients.Compared to metformin alone,the combination of liraglutide and metformin significantly lowered fasting blood sugar,postprandial blood glucoseafter 2 hours,HbA1c,HOMA-IR,FINS,BMI,as well as LH,FSH,and total testosterone in patients with PCOS.It improved lipid levels,helped establish menstrual cycles,and increased the normal ovulation rate and natural conception rate in these patients.However,there was a significantly higher incidence of gastrointestinal reactions in the liraglutide plus metformin group,and the difference was statistically significant(P＜0.05).Conclusion The combination of liraglutide and metformin can improve glucose and lipid metabolism in patients with polycystic ovary syndrome(PC OS),reduce levels of LH,FSH,and total testosterone,help establish regular menstrual cycles,and increase ovulation and pregnancy rates,but it significantly increases gastrointestinal side effects.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

BACKGROUND: Diabetic foot is a complex condition with high incidence, recurrence, mortality, and disability rates. Current treatments for diabetic foot ulcers are often insufficient. This study was conducted to identify potential therapeutic targets for diabetic foot. METHODS: Datasets related to diabetic foot and diabetic skin were retrieved from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were identified using R software. Enrichment analysis was conducted to screen for critical gene functions and pathways. A protein interaction network was constructed to identify node genes corresponding to key proteins. The DEGs and node genes were overlapped to pinpoint target genes. Plasma and chronic ulcer samples from diabetic and non-diabetic individuals were collected. Western blotting, immunohistochemistry, and enzyme-linked immunosorbent assays were performed to verify the S100 calcium binding protein A9 (S100A9), inflammatory cytokine, and related pathway protein levels. Hematoxylin and eosin staining was used to measure epidermal layer thickness. RESULTS: In total, 283 common DEGs and 42 node genes in diabetic foot ulcers were identified. Forty-three genes were differentially expressed in the skin of diabetic and non-diabetic individuals. The overlapping of the most significant DEGs and node genes led to the identification of S100A9 as a target gene. The S100A9 level was significantly higher in diabetic than in non-diabetic plasma (178.40 ± 44.65 ng/mL vs. 40.84 ± 18.86 ng/mL) and in chronic ulcers, and the wound healing time correlated positively with the plasma S100A9 level. The levels of inflammatory cytokines (tumor necrosis factor-α, interleukin [IL]-1, and IL-6) and related pathway proteins (phospho-extracellular signal regulated kinase [ERK], phospho-p38, phospho-p65, and p-protein kinase B [Akt]) were also elevated. The epidermal layer was notably thinner in chronic diabetic ulcers than in non-diabetic skin (24.17 ± 25.60 μm vs. 412.00 ± 181.60 μm). CONCLUSIONS S100A9 was significantly upregulated in diabetic foot and was associated with prolonged wound healing. S100A9 may impair diabetic wound healing by disrupting local inflammatory responses and skin re-epithelialization.

Objective To investigate the distribution characteristics of antibiotics in source water and their health risks to human body in Yichang City, and to provide a scientific basis for the prevention and control of new types of pollution such as antibiotics in drinking water. Methods Solid phase extraction (SPE) was used for enrichment, and ultra-high performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) was used to detect and analyze the content of five types of antibiotics including sulfonamides, tetracyclines, chloramphenicol, quinolones and β-lactams in the main drinking water sources of Yichang City. The human health risk assessment of these antibiotics was conducted. Results All five types of antibiotics were detected in the source water of Yichang City, and the detection rate was 6.25% to 81.25%. The total detection rate of β-lactam antibiotics was the highest, and the highest detection concentration of norfloxacin was 213.9 ng/L. The health risk assessment of 11 antibiotics detected in the source water showed that these antibiotics would not cause obvious health harm to human body, but the risk entropy (RQ_H) tended to increase with the younger age. Conclusion The distribution level of antibiotics in source water of Yichang City will not cause obvious health harm to human body.
