Objective To explore the effect and mechanism of Sechang Zhixie Powder(SCZXS)on mice with acute diarrhea caused by castor oil.Methods The mice were randomly divided into blank control group,model control group,montmorillonite powder group(1.4 g·kg-1),SCZXS-L group(0.9 g·kg-1),SCZXS-M group(1.8 g·kg-1)and SCZXS-H group(3.6 g·kg-1),10 mice in each group.After continuous administration of 7 days,the acute diarrhea model of mice was prepared by oral administration of castor oil(0.01 mL·g-1).The diarrhea of mice was observed within 4 hours of castor oil administration,and the rate of loose stool,degree of loose stool,and diarrhea index were calculated;the levels of DAO,D-LDH,VIP,and SS in the colon were determined by enzyme-linked immunosorbent assay;The morphological changes in the colon tissue of mice were observed after HE staining and the thicknesses of the mucosal and muscular layers of the colon were quantified;AB-PAS staining was performed to observe the effect on mucin in the colon;and the expression of AQP3,Occludin,and ZO-1 in the colon were quantified by immunohistochemistry.Results Compared with the model control group,the rate of loose stool,degree of loose stool,and diarrhea index of the mice in the SCZXS groups tended to decrease,but the difference was not statistically significant.Compared with the model control group,the flat luminal surface of the mice in the SCZXS-M and SCZXS-H group were significantly thickened(P<0.01),and the amount of VIP in the colon was significantly decreased(P<0.05,P<0.01),and that of DAO in the colon was significantly decreased(P<0.01),Occludin and ZO-1 expression were significantly increased(P<0.01),the mucin area ratio was significantly increased(P<0.05)in the SCZXS-M group,and AQP3 expression was significantly increased(P<0.05)in the SCZXS groups.Conclusions SCZXS can improve acute diarrhea induced by castor oil in mice.and its mechanism may be related to the regulation of gastrointestinal hormones and AQP3.In addition,SCZXS improves intestinal damage caused by diarrhea and protects the intestinal barrier.

Objective:To investigate the potential mechanism of cellular senescence-related mitochondrial autophagy genes in diabetic retinopathy (DR).Methods:The DR gene datasets GSE53257 and GSE60436 from the GEO database and screened the differentially expressed genes (DEG) were downloaded. Cellular senescence-related genes and mitochondrial autophagy-related genes from the GeneCards database, and the intersection of the two to obtain the DR-related differentially expressed genes (CSRMRDEG) were collected. The obtained CSRMRDEG was subjected to Gene Ontology (GO) functional enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathway enrichment analysis, protein-protein interaction network (PPI) analysis, and hub gene identification using Maximal Clique Centrality (MCC), Degree, Maximum Neighborhood Component (MNC)、Edge Percolated Component (EPC) and Closeness algorithms. Gene Set Enrichment Analysis (GSEA) was conducted to obtain the enriched pathways of DEG, and ssGSEA immune infiltration analysis was performed to screen the correlation between immune cells and DR. The diagnostic efficacy of hub genes for DR was evaluated by drawing the receiver operating characteristic (ROC) curve and calculating the area under the curve (AUC). Meanwhile, the Wilcoxon rank sum test was used to compare the differences in the infiltration level of immune cells between the DR Group and the control group.Results:23 DR-related CSRMRDEG were obtained. GO analysis showed that they were mainly enriched in the pathways of dicarboxylic acid, biosynthetic process of folate-containing compounds, tetrahydrofolate conversion, mitochondrial matrix, mitochondrial endomembrane, structural components of ribosomes, and glutamate transmembrane transporter protein activity. The results of KEGG pathway enrichment analysis showed that CSRMRDEG was highly enriched in pathways such as the folate carbon pool, biosynthesis of cofactors, and pyruvate metabolism. The PPI analysis results show that there are 16 related CSRMRDEG. Five algorithms (MCC, Degree, MNC, EPC, Closeness) obtained the nine Hub genes. The results of ROC curve analysis showed that the AUC of the expression levels of 9 hub genes for diagnosing DR ranged from 0.7-0.9. The ssGSEA results showed that there were statistically significant differences in Wilcoxon of central memory CD4 + T cells, macrophages, natural killer cells, and helper T cell 1 between the DR group and the control group ( Z=-2.85, -2.23, -2.10, -2.52; P<0.05). Conclusion:Mitochondrial autophagy genes related to cellular senescence are potential diagnostic targets for DR.

The incidence of hypertriglyceridemic acute pancreatitis(HTG-AP)has been gradually rising in recent years.According to published findings,high triglyceride levels are strongly associated with the severity of acute pancreatitis,and may lead to a higher incidence of complications and worse prognosis.However,the risk factors associated with HTG-AP have not been systematically explored.Early identification and effective management of high triglyceride levels and other potential causes thereof are crucial for reducing the recurrence of acute pancreatitis in clinical practice.Herein,we reviewed the predictive factors of HTG-AP from the perspectives of etiology,pathogenesis,and the relevant biomarkers,such as C-reactive protein,Ca2+,PT,and D-dimer.We aim to provide important early warning signals for clinicians,thereby helping develop personalized treatment protocols and building a more accurate risk prediction model.

Objective:To evaluate long-term outcomes of endoscopic papillectomy (EP) for duodenal papillary adenomas and to identify risk factors for incomplete resection.Methods:Clinical data of 180 patients diagnosed as having duodenal papillary adenoma via postoperative pathology after EP in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2010 to December 2022 were retrospectively analyzed. Patients were divided into two groups based on their postoperative margin status: the complete resection group (negative resection margins) and the incomplete resection group (positive/uncertain resection margins). Recurrence rates were compared between the two groups, and logistic regression analysis was performed to identify risk factors for incomplete resection.Results:Among the 180 patients included in the study, 137 underwent complete resection, and 43 had incomplete resections. Recurrence rate was significantly higher in the incomplete resection group than that in the complete resection group (30.2% VS 15.3%, χ2=4.75, P=0.029). logistic regression analysis indicated that high-grade intraepithelial neoplasia was an independent risk factor for incomplete resection ( OR=2.43, 95% CI:1.12-5.26, P=0.024). Conclusion:Patients with incomplete resection after EP have a higher recurrence rate in the long-term follow-up. High-grade intraepithelial neoplasia is an independent risk factor for incomplete resection. Close surveillance and aggressive management are warranted for patients with positive or uncertain resection margins to mitigate the recurrence risk.

Objective:To retrieve, evaluate, and integrate evidence on the humanistic care practice of physical restraints for adult patients in the ICU to inform the management of physical restraints for clinical ICU patients.Methods:Expert consensus, group standards, systematic reviews, clinical decisions, best practices, guidelines, evidence summaries, and other types of literature related to the humanistic care of physical restraints for adult patients in the ICU were electronically searched in Chinese and English databases, relevant association websites, and guideline websites.
