OBJECTIVE To investigate the effects and mechanism of Yigan huayu formula in alleviating liver fibrosis in mice. METHODS Mice were randomly divided into blank group （normal saline）， model group （normal saline）， Yigan huayu formula low- and high-dose groups （28.98， 57.96 g/kg， calculated by crude drug）， with 8 mice in each group. Except for the blank group， the liver fibrosis model was induced by intraperitoneal injection of 15%CCl 4 -olive oil solution. From the third week， the mice received the medicine/normal saline intragastrically， once a day， for 4 consecutive weeks. After the last medication， liver indexes were calculated， the activities of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in serum， as well as the hydroxyproline （HYP） content in liver tissue， were measured. Liver histopathology was evaluated. Differentially expressed proteins （DEPs） in liver tissue were analyzed based on proteomics， followed by bioinfo rmatics analysis. The expressions of core DEPs were validated using Western blot （WB） and immunohistochemistry （IHC） methods. RESULTS Compared with the blank group， the model group showed significantly elevated liver indexes， serum activities of ALT and AST， and hepatic HYP content （ P ＜0.05）， along with obvious pathological damage and collagen deposition. Compared with the model group， the above indexes of mice in the Yigan huayu formula high-dose group were decreased significantly （ P ＜0.05）， with marked improvement in liver pathological damage and collagen deposition. Proteomics identified 210 DEPs between the model group and Yigan huayu formula high-dose group. DEPs were significantly enriched in extracellular matrix （ECM）-receptor interaction and lipid metabolism pathways. WB and IHC confirmed that Yigan huayu formula could significantly inhibit the abnormally elevated expressions of collagen type Ⅳ alpha1 chain （COL4A1）， secreted protein acidic and rich in cysteine （SPARC）， vitronectin （VTN） and laminin subunit alpha5 （LAMA5） in liver tissue of mice （ P ＜0.05）. CONCLUSIONS Yigan huayu formula may exert anti-hepatic fibrosis effects by inhibiting the expressions of proteins such as COL4A1， LAMA5， SPARC， and VTN， thereby blocking the ECM-receptor interaction signaling pathway， and subsequently suppressing excessive ECM deposition and basement membrane remodeling.

Colitis is a common inflammatory bowel disease whose pathogenesis is related to immune regula-tion and intestinal microbial homeostasis.Exosomes are membrane vesicles secreted by cells that contain proteins,lipids,and other substances.Stem cells and macrophages can participate in the regulation of related diseases by secreting exosomes.It has been found that exosomes of stem cell and macrophage origin are closely involved in the regulation of colitis,and exosomes derived from stem cells,especially mesenchymal stem cells,play an important role in anti-colitis.This article reviews the role and possible mechanisms of mesenchymal stem cell-based and macrophage-derived exosomes in the regulation of colitis,aiming to provide ideas for in-depth study of colitis and new strategies for its treatment.

Objective:To investigate the influence of serum C-X-C motif chemokine ligand 9 (CXCL9) and C-X3-C motif chemokine ligand 1 (CX3CL1) on the development of preeclampsia in patients with gestational diabetes mellitus (GDM).Methods:A retrospective analysis was conducted on the clinical data of 398 GDM patients admitted to Huangshi Aikang Hospital from January 2021 to August 2024. Based on the occurrence of preeclampsia, patients were divided into the GDM-preeclampsia group (51 cases) and the simple GDM group (347 cases). The baseline data, blood glucose indicators, four lipid items, platelet count (PLT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen, serum creatinine, and 24-hour urinary protein quantification were compared between the two groups. The influencing factors for GDM complicated by preeclampsia were analyzed, and the predictive value of serum CXCL9 and CX3CL1 for the onset of preeclampsia in GDM patients was assessed. Measurement data with a normal distribution were expressed as Mean ± SD, and the t'-test was used for intergroup comparisons when variances were unequal; measurement data with a skewed distribution were expressed as M ( Q1, Q3), and the Wilcoxon rank-sum test was used for intergroup comparisons; counting data were expressed as case (%), and the χ2 test was used for intergroup comparisons. Unconditional logistic regression models were used to analyze the risk factors for preeclampsia in GDM patients. The predictive value of serum CXCL9 and CX3CL1 levels for preeclampsia in GDM patients was analyzed using the receiver operator characteristic (ROC) curve. Results:Pre-pregnancy body mass index, glycated hemoglobin, and 24-hour urinary protein quantification in the GDM-preeclampsia group [(24.50±3.74) kg/m 2, (5.68±0.52)%, 0.42 (0.17, 0.69) g] were all higher than those in the simple GDM group [(22.70±2.97) kg/m 2, (5.42±0.44)%, 0.30 (0.10, 0.44) g], with statistically significant differences between groups (statistic values: t'=3.90, t'=3.85, U=2.70; P values: <0.001, <0.001, 0.007, respectively). Serum CXCL9 levels in the GDM-preeclampsia group [(111.69±36.65) ng/L] were lower than those in the simple GDM group [(200.16±85.57) ng/L], while CX3CL1 levels [(2.22±0.29) μg/L] were higher than those in the simple GDM group [(1.83±0.35) μg/L], with statistically significant differences ( t' values: 7.28 and 7.58, respectively; both P<0.001). Multivariate logistic regression analysis showed that increased CX3CL1 ( OR=1.562, 95% CI: 1.237-1.972), decreased CXCL9 ( OR=0.979, 95% CI: 0.970-0.989), increased pre-pregnancy body mass index ( OR=1.226, 95% CI: 1.060-1.417), and increased glycated hemoglobin ( OR=3.474, 95% CI: 1.192-10.122) were associated with an increased risk of developing preeclampsia in GDM patients ( P values: <0.001, <0.001, 0.006, 0.023, respectively). The ROC curve showed that the area under the curve for serum CXCL9 (sensitivity: 88.24%, specificity: 70.89%) and CX3CL1 (sensitivity: 78.43%, specificity: 69.16%) in predicting preeclampsia in GDM patients were both >0.50 ( P values: 0.015, 0.034, respectively), indicating that both have high predictive efficacy, with CXCL9 being slightly superior to CX3CL1. Conclusion:Decreased serum CXCL9 and increased CX3CL1 are associated with an increased risk of preeclampsia in GDM patients. Both can serve as auxiliary predictive indicators for preeclampsia in GDM patients.

The prevalence of chronic constipation among the elderly is significant, exerting adverse effects on both their physical and mental health.Presently, pharmacological therapy remains the predominant treatment modality for elderly patients with chronic constipation; however, prolonged use can lead to drug dependence, tolerance, and adverse effects.This article systematically reviews non-pharmacological interventions for chronic constipation in elderly patients, both domestically and internationally, aiming to provide a comprehensive reference for clinical practice.

Objective To explore the changing trend in the disease burden of gout in China from 1990 to 2021, and analyze the incidence, prevalence, and disability-adjusted life years (DALYs) by age and gender, with comparisons to global patterns, and to predict the disease burden of gout in China in 2030. Methods Data from the Global Burden of Disease (GBD) database were used to analyze changes in gout burden. Joinpoint regression was used to estimate the average annual percentage change (AAPC) with 95% confidence intervals (CIs). Comparative analyses were conducted on data from China and the world, and an ARIMA model was used to project China's gout burden in 2030. Results From 1990 to 2021, China's age-standardized incidence rate (ASIR) rose from 122.52 to 151.61/100,000, exceeding the global rise from 93.09 to 109.07/100,000. The age-standardized prevalence rate (ASPR) in China increased from 640.67/100,000 to 810.35/100,000, compared to a global rise from 536.54/100,000 to 653.81/100,000. The age-standardized DALYs rate (ASDR) in China increased from 20.2/100,000 to 25.43/100,000, surpassing the global increase from 16.67/100,000 to 20.21/100,000. AAPCs for ASIR, ASPR, and ASDR in China were 0.70%, 0.77%, and 0.75%, respectively, all higher than global rates. Middle-aged and elderly men faced the highest burden. It was predicted that there will be a decline in China's ASIR and ASPR by 2030, while ASDR will remain stable. Conclusion The disease burden of gout in China has increased significantly, outpacing global trends. Targeted interventions for hyperuricemia, particularly in elderly men, are crucial to reduce the future disease burden.
