Objective:To investigate the pharmacological mechanism of Compound Xuanju Capsule in the treatment of erectile dysfunction(ED)by using network pharmacology and molecular docking technology.Methods:The active ingredients and targets of Compound Xuanju Capsule were screened using Traditional Chinese Medicine Systematic Pharmacology Database and Analysis Platform(TCMSP).TTD,OMIM,DrugBank and GeneCards databases were used to obtain genes related to ED,and the union of the results was taken as the disease genes of ED.The common target of drug and disease was taken as the potential target of Compound Xuanju Capsule in ED,and the drug-disease interaction network was constructed by using Cytoscape software.The protein-protein interaction(PPI)network was constructed by using String database,which was then imported into Cytoscape to identify the key target.Based on the drug-disease intersection genes,GO and KEGG enrichment analyses were performed to predict the relevant signaling pathways and molecular mechanisms of Compound Xuanju Capsule for the treatment of ED.Autodock software was used to perform molecular docking between the active ingredients and the core targets.Results:Forty chemical components of Compound Xuanju Capsule were screened,and 239 predicted targets were obtained.A total of 1 907 ED-related genes were screened,and 97 common targets were identified between Compound Xuanju Capsule and ED,among which the core targets included EGFR,ESR1,HIF1A,PTGS2,and STAT3.The signaling pathways obtained by KEGG enrichment analysis included calcium signaling pathway,HIF-1 signaling pathway,PI3K-Akt signaling pathway,cGMP-PKG signaling pathway,relaxin signaling pathway,Serotonergic synapse signaling pathway.The molecular docking results showed that there were molecular binding sites between the key active ingredients and the core targets with strong binding activity.Conclusion:Compound Xuanju Capsule may treat ED through multi-target pathways such as anti-inflamnmato-ry and improving cellular oxidative stress.

Objective:To investigate the effects of 3 D laparoscopic radical resection prostatectomy(LRP)on urinary control and sexual function of patients with prostatic cancer.Methods:A total of 268 patients who were treated with LRP in the Fifth People's Hospital of Huai an City from January 2019 to May 2022 were selected and divided into 2 groups according to surgical methods,with 134 cases in each group.The patients in the control group were treated with traditional LRP,and the 3D LRP was used in the observa-tion group.The clinical effects of the two groups were compared.Results:The patients in observation group had less blood loss([135.62±13.58]mL vs[143.18±14.89]mL)and shorter indwelling catheter time([8.26±1.47]d vs[9.78±1.73]d)compared with control group,but the operation time([160.52±10.78]min vs[154.47±10.41]min)was longer than that in the control group(P＜0.05).The recovery of sexual function and urinary control in the observation group was better than that in the con-trol group after 3,6 and 12 months of the surgery(P＜0.05).After one month of surgery,the scores of ICIQ-SF and 1 h urine pad test were lower than those of the control group.The EPIC-UIN score([72.63±6.85]points vs[67.15±5.09]points)of the observation group was higher than that of the control group(P＜0.05).The patients in the observation group had lower level of residual urine volume([60.26±6.63]mL vs[76.89±7.89]mL),higher maximum urine flow rate([7.52±0.46]mL/s vs[6.17±0.43]mL/s)and detrusor pressure([85.19±7.18]mL vs[76.29±6.85]mL)at maximum urine flow rate compared with the control group(P＜0.05).There was no difference in the incidence of complications between the observation group and the control group(5.97％vs 8.27％,P＞0.05).The recurrence rate of tumor 3 years after operation in the observation group was lower than that in the control group(11.94％vs 29.10％,x2=12.102,P＜0.05).Conclusion:3D LRP has obvious advantages in surgical clarity and preci-sion,which reduces the risk of postoperative complications and improves urinary control ability and sexual function of patients.

Single-cell assay for transposase-accessible chromatin sequencing(scATAC-seq)is a power-ful technique for studying cellular heterogeneity and gene regulatory networks,widely applied in epigenet-ic research.However,the complexity of data analysis workflows and high programming requirements have limited its broader adoption among non-programmer researchers.To address this issue,we developed Sig-nac.UIO,a modular and visual scATAC-seq analysis platform based on the R Shiny framework,integra-ting mainstream tools such as Signac and Seurat.The platform includes ten key modules covering quality control,cell filtering,dimensionality reduction,clustering,differential analysis,cell annotation,path-way enrichment,motif analysis,and transcription factor footprinting.Through a graphical user interface,users can perform full analyses and obtain interactive visualization results.The platform's stability and u-tility have been validated using a public PBMC dataset and it is currently deployed online(https://xula-bgdpu.org.cn/Signac.UIO),providing an efficient and user-friendly tool for single-cell epigenomics re-search.

Objective:To explore the correlation between serum creatinine/cystatin C ratio (Scr/CysC) and muscle mass and muscle strength, and evaluate the predictive value of Scr/CysC for all-cause mortality in peritoneal dialysis patients.Methods:It was a prospective cohort study. The patients who received regular peritoneal dialysis treatment for more than 3 months and had stable conditions in the Renal Division of Peking University First Hospital from April 1, 2011 to August 1, 2012 were included, and the clinical data were collected. The patients were divided into the male group and the female group, and the differences of clinical data between the two groups were compared. The lean body mass (LBM) directly measured by the dual-energy X-ray absorptiometry (LBM-DEXA) was used as the reference gold standard and compared with the LBM estimated by the creatinine method (LBM-CK) and the anthropometric method (LBM-A). Muscle strength was measured by a grip strength meter for the dominant hand grip strength. Pearson correlation and multiple linear regression analysis method were used to analyze the correlations between Scr/CysC and LBM as well as grip strength, and subgroup analyses were conducted according to gender groups. Cox regression model was used to analyze the value of Scr/CysC in predicting all-cause mortality in peritoneal dialysis patients.Results:A total of 213 peritoneal dialysis patients were included in this study, including 95 males (44.6%) and 118 females (55.4%). The age was (56.46±12.42) years old. The dialysis age was 24.0 (9.0, 52.5) months. The baseline Scr/CysC was (1.77±0.73). LBM-DEXA ( t=-17.764, P<0.001), LBM-CK ( t=-7.702, P<0.001), LBM-A ( t=-16.813, P<0.001), grip strength ( t=-11.083, P<0.001) and Scr/CysC ( t=-2.965, P=0.003) in the male group were all significantly higher than those in the female group. Pearson correlation analysis showed that Scr/CysC was positively correlated with LBM-DEXA ( r=0.204, P=0.003), LBM-CK ( r=0.279, P<0.001), LBM-A ( r=0.198, P=0.004), and grip strength ( r=0.341, P<0.001). Multiple linear regression analysis showed that Scr/CysC wasn't independently correlated with LBM-DEXA, but was independently correlated with grip strength ( β=0.134, P=0.006). Cox regression analysis showed that baseline Scr/CysC was not an independent influencing factor of all-cause mortality in peritoneal dialysis patients ( HR=1.005, 95% CI 0.751-1.346, P=0.972). Conclusion:Scr/CysC is associated with muscle mass and muscle strength in peritoneal dialysis patients, but has no value in predicting all-cause mortality in peritoneal dialysis patients.

This study was aimed at understanding the relationships among the drug resistance and genome characteristics of group A Streptococcus in Jiangsu Province.A total of 149 group A Streptococcus strains were collected from hospitals between 2016 and 2023.Thirteen antimicrobial minimal inhibitory concentrations were detected with the micro-dilution broth method.The GAS strains were typed with emm genotyping analysis and whole genome sequencing,to determine the carriage rates of drug resistance genes and the evolutionary relationships among strains.The resistance rates of 149 GAS strains to erythromy-cin,tetracycline,and clindamycin exceeded 90％,whereas the strains showed sensitivity to 8 different antibiotics,including penicillin.Notably,the resistance rates to erythromycin,tetracycline,and clindamycin consistently increased over time.All strains were classified into 9 emm types,among which emm12 accounted for the highest proportion(77/149;51.68％).Signifi-cant statistical differences were observed among emm types,in terms of the drug resistance rate,number of resistant species,and prevalence of drug resistance genes.Furthermore,SNP evolutionary tree analysis revealed 3 distinct clusters within the GAS strains:emm12,emm1,and other emm types.emm 12 and emm1 were the dominant GAS strains in Jiangsu Province.Most isolates were resistant to erythromycin,tetracycline,and clindamycin.Differences in phenotypes and genomic characteris-tics were observed among emm types.

Objective To observe the early changes of vault after implantation of posterior chamber phakic intraocular lens implantable collamer lens(ICL),and investigate the effect of different implantation axes on the early vault changes.Methods A prospective,parallel cohort study was performed,enrolling a total of 124 eyes of who underwent ICL(V4c)implantation in the refractive clinic.The changes of vault were observed by scheimpflug tomography(Pentacam)and anterior segment optical coherence tomography(CASIA2)at 1 day,1 week and 1 month after surgery.Results The ICL vault declined significantly by approximately(108.2±82.4)μm 1 week after surgery with the proportion of 16.6%±12.1%compared with the values 1 day after surgery(P<0.001),and then remained stable.Within 1 month after surgery,excluding the difference in vault baseline at 1 day after surgery,the proportion of vault decline in the middle vault group(250-749 μm)and the high vault group(≥750 μm)was similar,and there was no statistically significant difference.We analyzed the relationship between ICL axial directions and vault and found that the vault decline of the horizontal ICL group stabilized quickly at 1 week after surgery,and the vault decline of the vertical ICL group was more significant within 1 month after surgery(P<0.05).Conclusion The vault of the ICL shows a downward trend in the early stage after implantation.The middle vault group and ICL in the horizontal position stabilizes faster,and the downward trend of the high vault group or ICL in the vertical position is more obvious.
