Objective:To analyze the expression level of protein arginine methyltransferase 5 (PRMT5) in pancreatic cancer tissues and its correlation with prognosis using bioinformatics methods, and to explore its potential mechanisms.Methods:Expression analysis of the PRMTs family members was performed based on the gene expression profiles of 178 pancreatic cancer tissues from the Gene Expression Profiling Interactive Analysis (GEPIA) database and 171 normal pancreatic tissues from the TCGA and GTEx databases. Using the median expression level of PRMTs family members in pancreatic cancer tissues as the cutoff, patients were divided into high-expression and low-expression groups, and Kaplan-Meier curves for overall survival (OS) and disease-free survival (DFS) were plotted. The correlation between PRMT5 expression and the expression of oncogenes such as KRAS, TP53, BRCA1, BRCA2, and SLC39A4 was analyzed. Functional enrichment analysis was conducted on genes similar to PRMT5, and a protein-protein interaction (PPI) network was constructed to analyze the interaction relationships among these similar genes. Pancreatic cancer PANC1 and AsPC-1 cells cultured in standard medium served as the control group, while PANC1 and AsPC-1 cells cultured in medium supplemented with the PRMT5 inhibitor EPZ015666 served as the intervention group. Cell viability was assessed using the CCK-8 assay, and cell cycle progression was analyzed by flow cytometry.Results:The expression level of PRMT5 in pancreatic cancer tissues was significantly higher than that in normal pancreatic tissues and showed a significant negative correlation with both OS and DFS. Patients with high PRMT5 expression had a shorter median survival time compared to those with low expression (17.2 months vs 19.5 months). PRMT5 expression was significantly positively correlated with the expression of oncogenes KRAS, TP53, BRCA1, BRCA2, SLC39A4, and KLF5. Genes similar to PRMT5 were primarily enriched in cell cycle-related signaling pathways, and NOP58 identified as a hub gene in the PPI network. Compared to the control group, the proliferation activity of PANC1 and AsPC-1 cells in the intervention group was significantly reduced [(67.3±1.9)% vs (100±4.4)% for PANC1; (60.5±2.7)% vs (100.0±1.7)% for AsPC-1], and the proportion of cells in the G1 phase was significantly increased [(51.6±0.7)% vs (35.3±2.7)% for PANC1; (51.2±0.9)% vs (29.7±2.2)% for AsPC-1]. All these differences were statistically significant (all P values <0.05). Conclusions:High expression of PRMT5 was closely associated with poor prognosis in pancreatic cancer patients, and it may contribute to pancreatic cancer progression by regulating the cell cycle.

OBJECTIVE To investigate the mechanisms of rutin in alleviating depressive symptoms associated with premenstrual dysphoric disorder(PMDD)characterized by liver qi stagnation syndrome.METHODS Network pharmacology was employed to identify the intersecting targets of action between PMDD and rutin.A protein-protein interaction network was constructed to screen core targets,followed by gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis.Molecular docking simulations validated rutin's binding affinity to core targets.The bilateral ovaries of female Wistar rats were removed,followed by artificial hormone induction.The rats were then randomly divided into normal group(10 rats)and modeling group(50 rats).PMDD rat model with liver qi stagnation syndrome was established via restraint stress.The successfully modeled rats were further divided into model group,fluoxetine group(positive control)and rutin group,with 12 rats in each group.The corresponding drug solutions or water were administered by gavage at 9:00 a.m.every day,continuing for two estrous cycles.The open-field test,forced swimming test and Y-maze test were utilized to evaluate the effects of rutin on the behavioral indexes of model rats.Additionally,the density of neuronal dendritic spines in the hippocampal tissues of the rats was observed.Serum brain-derived neurotrophic factor(BDNF)levels and the expressions of BDNF,tyrosine kinase receptor type B(TrkB),synuclein(Syn),and postsynaptic density protein 95(PSD95)in hippocampal tissues were quantified,respectively.RESULTS Network pharmacology and molecular docking revealed the core targets through which rutin ameliorated PMDD characterized by liver qi stagnation syndrome included BDNF,TrkB,PSD65,Syn,etc.The results of experimental validation demonstrated that rutin significantly increased the spontaneous alternation behavior scores of PMDD model rats with liver qi stagnation syndrome during the non-receptive phase,shortened their immobility time during the forced swimming test,and enhanced the density of neuronal dendritic spines in the hippocampal tissues.Additionally,rutin upregulated the levels of serum BDNF and the protein expressions of BDNF,TrkB and Syn in the hippocampal tissues(P<0.05).However,it had no significant effect on the above indexes in model rats during the receptive phase(P>0.05).CONCLUSIONS Rutin ameliorates depressive symptoms,enhances spatial memory capabilities,and reduces neuronal damage in PMDD model rats with liver qi stagnation syndrome.These effects may be associated with the activation of BDNF/TrkB signaling pathway and upregulation of Syn protein expression.

Objective:To investigate the impact of body mass index (BMI) on the postoperative complications of open pancreaticoduodenectomy (OPD).Methods:The preoperative, operative and postoperative data of 234 patients who underwent OPD in the Department of the Hepatobiliary and Pancreatic Surgery of First Affiliated Hospital affiliated to Naval Medical University from January 2015 to June 2016 were analyzed retrospectively. According to the Asian BMI standard, the patients were divided into three groups: underweight group (BMI<18.5 kg/m 2, n=32), normal weight group (18.5 kg/m 2≤BMI<23.0 kg/m 2, n=110) and overweight group (BMI≥23.0 kg/m 2, n=92). Normal weight group was compared with underweight group and overweight group, respectively, to analyze the relationship between BMI and intraoperative parameters and major postoperative complications of OPD. Results:The incidence of diabetes in underweight group was lower than that in normal weight group, and the proportion of ASA score 3 in underweight group was higher than that in normal weight group, and there were significantly statistical differences (both P value <0.05). There was no significant difference on the other variables between underweight group, normal weight group and overweight group. The operation time, intraoperative hemorrhage volume >800 ml and intraoperative blood transfusion rate were not statistically different between underweight group and normal weight group, but overweight group had obviously higher intraoperative blood transfusion rate than normal weight group and the difference was statistically significant ( P<0.05). Underweight group had more postoperative intraperitoneal hemorrhage and postoperative blood transfusion rate than normal weight group, and the readmission rate in underweight group was less than that in normal weight group; the incidence of clinically related-post operative pancreatic fistula, postoperative infection, gastrointestinal bleeding and delayed gastric emptying in overweight group were significantly higher than those in normal weight group, and there were significantly statistical differences (all P value <0.05). In underweight group, normal weight group and overweight group, the average length of hospital stay were 9.9 days, 11.3 days, 15 days, and the total hospitalization expenses were 63663.04 yuan, 66241.78 yuan and 80484.31 yuan, respectively. Conclusions:Compared to normal weight patients, the difficulty of OPD in underweight patients does not increase, while the difficulty of OPD in overweight patients increases. Underweight and overweight could both increase the postoperative complications of OPD to some extent.

Objective:To explore the diagnostic value of serum C-C chemokine ligand 5 (CCL5) in assessing the degree of liver fibrosis in patients with metabolic-associated fatty liver disease (MAFLD).Methods:71 MAFLD patients who visited the Department of Integrated Traditional and Western Medical Hepatology, Third Hospital of Hebei Medical University, and underwent liver biopsy histopathology examinations between October 2021 and June 2023 were selected for diagnostic testing. Simultaneously, 71 healthy subjects who underwent physical examinations at the physical examination center of the hospital were selected as the control group. Serum CCL5 levels were detected using an enzyme-linked immunosorbent assay (ELISA). Routine blood tests, liver and kidney function tests, and other tests were conducted to analyze the expression level of CCL5 and its correlation with the above indicators. The aspartate aminotransferase/platelet ratio index (APRI) and fibrosis 4 index (FIB-4) were calculated. SPSS 26.0 software was used for statistical analysis. The area under the receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficacy of CCL5 for the degree of liver fibrosis in MAFLD. The combined diagnostic efficacy of APRI and FIB-4 was further analyzed for the degree of liver fibrosis in MAFLD.Results:The expression level of serum CCL5 gradually increased with the increase in liver fibrosis stage in patients with MAFLD, and the difference was statistically significant ( P<0.05). The AUC value of serum CCL5 for diagnosing significant liver fibrosis in MAFLD patients was 0.775, with a sensitivity of 65.7%, a specificity of 80.6%, and an optimal cutoff value of 49.845 ng/ml. The CCL5 and FIB-4 combination had the highest diagnostic value for significant liver fibrosis in patients with MAFLD, with an AUC of 0.802, a sensitivity of 91.4%, and a specificity of 61.1%. Conclusion:CCL5 has a high diagnostic value for significant liver fibrosis in MAFLD patients. Therefore, it is expected to become a non-invasive diagnostic marker for assessing the degree of liver fibrosis in MAFLD patients.

Objective To evaluate the value of perioperative multimodal stratified analgesia guided by PPRS-CYMZ 2.0. Methods One hundred and sixteen patients of both sexes, aged 16-85 yr, of A-merican Society of Anesthesiologists physical statusⅠ-Ⅲ, scheduled for elective surgery in our hospital in August 2016, were included in this study and assigned into empirical analgesia group(group E, n=79) and stratified analgesia group(group S, n=73). The risk of postoperative pain was estimated by an expe-rienced associate chief anesthesiologist based on his clinical experience, and the perioperative analgesic protocol was determined in group E. The risk of postoperative pain was assessed using the perioperative pain risk scale PPRS-CYMZ 2.0 by another experienced associate chief anesthesiologist, the risk was stratified according to the scores, and the corresponding stratified analgesic protocol was determined in group S. Vis-ual analog scale scores and parents′satisfaction with analgesia were recorded on postoperative day 30. The requirement for preventive analgesia, total pressing times of patient-controlled analgesia(PCA)pump in 0-6 h, 6-24 h and 24-72 h periods, PCA background infusion dose and consumption of rescue analgesics were recorded. The development of adverse events during postoperative hospital stay and postoperative re-covery were also recorded. Analgesia-related parameters of medical economics were calculated. Results There was no significant difference in postoperative pain risk stratification between group E and group S(P>0.05), and the majority of patients were at moderate risk. Compared with group E, no significant change was found in visual analog scale scores on postoperative day 30, PCA background infusion dose or incidence of postoperative adverse effects(P>0.05), the requirement for preventive analgesia and satisfaction scores were significantly increased in high risk patients, the consumption of rescue analgesics was decreased in moderate risk patients(P<0.05), no significant change was found in the total pressing times of PCA pump in each time period in low risk patients(P>0.05), the total pressing times of PCA pump was significantly decreased, and the direct analgesic cost per patient and total analgesic cost were decreased in moderate and high risk patients, and the first ambulation time and length of postoperative hospital stay were shortened in high risk patients in group S(P<0.05). Conclusion PPRS-CYMZ 2.0 can achieve perioperative multi-modal stratified analgesia and individualized treatment.

The present paper is aimedto investigate the effect of basic fibroblast growth factor (bFGF) on proliferation, migration and differentiation of endogenous neural stem cell in rat cerebral cortex with global brain ischemia-reperfusion. A global brain ischemia-reperfusion model was established. Immunohistochemistry was used to observe the pathological changes and the expression of BrdU and Nestin in cerebral cortex. RT-PCR was used to measure the NSE mRNA in brain tissue. The results of measurements indicated that in sham operation group, there was no positive cell in cerebral cortex, and the content of NSE mRNA did not change. In the operation group, the expression of BrdU and Nestin increased significantly at the end of the 3rd day, and peaked on the 7th day. NSE mRNA expression did not significantly increase. In bFGF group, compared with sham operation group and model group, the number of BrdU-positive and Nestin-positive cells increased significantly at each time point (P<0. 05), and peaked at the end of the 11th day, and the content of NSE mRNA increased significantly (P<0. 05). This research demonstrated that the proliferation of endogenous neural stem cells in situ could be induced by global cerebral ischemia and reperfu- sion, and could be promoted and extended by bFGF. In additiion, bFGF might promote endogenous neural stem cells differentiated into neurons.
