Objective:To investigate the clinical efficacy of compound sabal berry tablets on overactive bladder symptoms in patients with benign prostatic hyperplasia after transurethral laser enucleation of the prostate.Methods:This study was a prospective study. Eighty patients with benign prostatic hyperplasia who underwent laser enucleation at Tongliao People's Hospital from January 2024 to December 2024 were included in this study. The patients were randomly divided into a study group and a control group using the random number table method, with 40 patients per group. The control group received 0.2 mg of tolterodine tartrate tablets twice a day after surgery. The study group was given compound sabal berry tablets (0.5 g orally three times a day) in addition to the treatment provided to the control group. Both groups of patients were treated for 4 weeks after surgery. The clinical efficacy of the two groups was compared, including the International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), Maximum Postoperative Urinary Flow Rate (Qmax), Post-Void Residual (PVR), and the incidence of postoperative bladder irritative symptoms.Results:The differences in the preoperative indicators, including IPSS, OABSS, Qmax, and PVR, between the two groups were not statistically significant (all P > 0.05). Preoperatively, in the control group, Qmax was (8.64 ± 2.83) mL/s, IPSS was (25.10 ± 4.37), OABSS was (10.52 ± 1.87), and PVR was (80.70 ± 6.34) mL; in the study group, the respective values were (9.12 ± 2.95) mL/s, (24.60 ± 4.53), (10.83 ± 1.73), and (80.10 ± 5.61) mL. Postoperatively, in the control group, Qmax was (20.30 ± 3.65) mL/s, IPSS was (8.50 ± 1.58), OABSS was (4.09 ± 0.52), and PVR was (9.70 ± 2.48) mL, while in the study group, the respective values were (21.40 ± 4.38) mL/s, (7.40 ± 1.76), (1.71 ± 0.36), and (9.00 ± 1.75) mL. Postoperatively, both groups showed a significant increase in Qmax, while IPSS, OABSS, and PVR all significantly decreased (all P < 0.05). Postoperatively, the IPSS and OABSS in the study group were significantly lower than those in the control group ( t = -3.28, -25.89, both P < 0.05). However, there were no statistically significant differences in Qmax and PVR between the two groups (both P > 0.05). The incidence of bladder irritative symptoms in the study group [12.50% (5/40)] was significantly lower than that in the control group [35.00% (14/40), χ2 = 8.64, P < 0.05]. Conclusions:Compound sabal berry tablets can reduce postoperative prostate symptoms and overactive bladder symptoms in patients undergoing transurethral laser enucleation of the prostate for benign prostatic hyperplasia, demonstrating a certain clinical efficacy.

ObjectiveTo investigate the mechanism of kidney-tonifying and liver-regulating cyclical therapy and its formula in regulating endometrial receptivity during the "implantation window" in rats with polycystic ovary syndrome (PCOS). MethodsSix rats were randomly selected from 36 SPF SD female rats as the normal group, and the remaining rats were administered letrozole to induce a PCOS model. By using a random number method, the rats were divided into the following groups: normal group, model group, Xiaoyaosan group (11.97 g·kg-1), Sanzi Yangmo decoction group (28.35 g·kg-1), cyclical therapy group (11.97/28.35 g·kg-1), and aspirin group (8 × 10-3 mg·kg-1). After 12 days of continuous administration by gavage (equivalent to three estrous cycles), female and male rats were co-housed. On the fifth day of pregnancy, the number of blastocyst implantation in each group was counted. Hematoxylin-eosin (HE) staining was used to observe the pathological morphology of rat endometrial tissue. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of estradiol (E2) and progesterone (P) in rat serum. Western blot was used to detect the protein expression of vascular endothelial growth factor (VEGF), progesterone receptor (PR), estrogen receptor (ER), androgen receptor (AR), and integrin(ITG) αvβ3 in rat endometrial blood vessels. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of miR-140-5 P, VEGF, vascular endothelial growth factor receptor 2 (VEGFR2), PR, ER, AR, and ITGαvβ3 in rat endometrium. ResultsCompared with normal group, the estrous cycle of the rats in model group continued to be in the estrus interval and the estrous cycle lost regular changes. The endometrium was significantly thinner, the number of uterine glands and blood vessels were significantly reduced (P<0.01), and the pregnancy rate was significantly reduced. Compared with the model group, each drug group restored the regular estrous cycle to varying degrees, and the endometrial thickness and the number of blood vessels were significantly improved (P<0.01). The pregnancy rate of each drug group increased, and the effect of the cycle therapy group could reach the normal level. The results of molecular biology experiments showed that compared with the normal group, the levels of serum E2 and P in the model group were significantly decreased (P<0.01), the expression of VEGF, ER, PR and ITGαvβ3 protein was significantly decreased (P<0.05,P<0.01), the expression of AR protein was significantly increased (P<0.01), the expression of miR-140-5P and AR mRNA was significantly increased (P<0.01), and the expression of VEGF, VEGFR2, ER, PR and ITGαvβ3 mRNA was significantly decreased (P<0.01). Compared with model group, the serum E2 level in the Xiaoyaosan group was significantly increased (P<0.01).The levels of E2 and P in serum of rats in Sanzi Yangmo decoction group, cycle therapy group and aspirin group were significantly increased (P<0.01). The expression of AR protein in each drug group was significantly decreased (P<0.01). The expression of VEGF and ITGαvβ3 protein in Xiaoyaosan group was significantly increased (P<0.01). The expression of VEGF, ER and PR protein in Sanzi Yangmo decoction group was increased to varying degrees (P<0.05,P<0.01). The expression of VEGF, PR, ER and ITGαvβ3 protein in the cycle therapy group and the aspirin group increased to varying degrees (P<0.05,P<0.01). The expression of miR-140-5P and AR mRNA in each drug group was significantly decreased (P<0.01). The expression of VEGF, VEGFR2, ER, PR and ITGαvβ3 mRNA in each drug group increased to varying degrees (P<0.05,P<0.01). Compared with Xiaoyaosan group and Sanzi Yangmo decoction group, the expression of miR-140-5P, VEGFR2, ER, PR, AR and ITGαvβ3 mRNA in the cycle therapy group were significantly different (P<0.05,P<0.01). ConclusionThe kidney-tonifying and liver-regulating cyclical therapy may reduce the activity of miR-140-5P, target the upregulation of VEGF expression, mediate angiogenesis, and promote endometrial angiogenesis, thereby playing a synergistic role in improving endometrial receptivity in PCOS-induced infertility. Its efficacy in increasing pregnancy rates surpasses that of Xiaoyaosan or Sanzi Yangmo decoction used alone.

Antimicrobial susceptibility testing was performed using the dilution method recommended by the Clinical and Laboratory Standards Institute(CLSI). Statistical analyses were conducted using WHONET 5.6 and SPSS 25.0 software.Results:A total of 4 385 Gram-positive bacterial isolates were obtained from 60 participating center. The top five pathogens were Staphylococcus aureus( n=1 544,35.2%),coagulase-negative Staphylococci( n=1 441,32.9%), Enterococcus faecium( n=574,13.1%), Enterococcus faecalis( n=385,8.8%),and α-hemolytic Streptococci( n=187,4.3%). The prevalence of methicillin-resistant Staphylococcus aureus(MRSA)and methicillin-resistant coagulase-negative Staphylococci(MRCNS)was 26.2%(405/1 544)and 69.8%(1 006/1 441),respectively. Notably,all Staphylococci remained susceptible to glycopeptide or daptomycin. Staphylococcus aureus demonstrated excellent susceptibility(>97.0%)to cephalobiol,rifampicin,trimethoprim-sulfamethoxazole,linezolid,minocycline,tigecycline,and eravacycline. No Enterococcus exhibiting resistance to linezolid were detected. Glycopeptide resistance was uncommon but more frequent in Enterococcus faecium(resistance to vancomycin and teicoplanin:both 1.7%)compared to Enterococcus faecalis(both 0.3%). The detection rates of MRSA and MRCNS exhibited significant regional variations across the country( χ2=17.674 and 148.650,respectively,both P<0.001). No vancomycin-resistant Enterococci were detected in central China. Institutional comparison demonstrated higher prevalence of MRSA( χ2=14.111, P<0.001)and MRCNS( χ2=4.828, P=0.028)in provincial hospitals than that in municipal hospitals.

Objective:To report the results of bacterial resistant investigation collaborative system(BRICS)on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2023,and provide reference for clinical tretment of bloodstream infections and prevention and control of bacterial resistance.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of BRICS were collected during January 2023 to December 2023. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute(CLSI). WHONET 5.6 and SPSS 25.0 were used to analyze the data.Results:During the study period,11 492 strains of Gram-negative bacteria were collected from 60 hospitals,of which 10 098(87.9%)were Enterobacterales and 1 394(12.1%)were non-fermentative bacteria. The top 5 bacterial species were Escherichia coli(50.0%), Klebsiella pneumoniae(26.1%), Pseudomonas aeruginosa(5.1%), Acinetobacter baumannii complex(5.0%)and Enterobacter cloacae complex(4.1%). The ESBL-producing rates in Escherichia coli, Klebsiella pneumoniae and Proteus mirablilis were 46.8%(2 685/5 741),18.3%(549/2 999)and 44.0%(77/175),respectively. The prevalence of carbapenem-resistant Escherichia coli(CREC)and carbapenem-resistant Klebsiella pneumoniae(CRKP)were 1.3%(76/5 741)and 15.0%(450/2 999);32.9%(25/76)and 78.0%(351/450)of CREC and CRKP were sensitive to ceftazidime/avibactam combination,respectively. 94.7%(72/76)and 90.2%(406/450)of CREC and CRKP were sensitive to aztreonam/avibactam combination. Furthermore,57.9%(44/76)and 79.1%(356/450)were sensitive to imipenem/relebactam combination. The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)complex was 64.6%(370/573),while more than 80.0% of CRAB complex was sensitive to tigecycline,eravacycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa(CRPA)was 17.0%(99/581). There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of important Gram-negative bacteria resistance among different regions in China,with statistically significant differences in the prevalence of CREC,CRKP,CRPA and CRAB complex( χ2=10.6,28.6,10.8 and 19.3, P<0.05). The prevalence of ESBL-producing Escherichia coli, CREC,CRAB complex and CRKP were higher in provincial hospitals than those in municipal hospitals( χ2=12.5,9.8,12.7 and 57.8,all P<0.01). Conclusions:Gram-negative bacteria are the main pathogens causing bloodstream infections in China,and Escherichia coli is ranked in the top,while the trend of Klebsiella pneumoniae increases continuously with time. CRKP infection shows a slow upward trend,CREC infecton maintains a low prevalence level,and CRAB complex infection continues to exhibit a high prevalence rate. The composition and resistance patterns of pathogens causing bloodstream infections vary to some extent across different regions and levels of hospitals in China.

OBJECTIVE:
Peritoneal fibrosis (PF) is an adverse event that occurs during long-term peritoneal dialysis, significantly impairing treatment efficiency and adversely affecting patient outcomes. Astragaloside IV (AS-IV), a principal active component derived from Astragalus membranaceus (Fisch.) Bunge, has exhibited anti-inflammatory and antifibrotic effects in various settings. This study aims to investigate the potential therapeutic efficacy and mechanism of AS-IV in the treatment of PF.
METHODS:
The PF mouse model was established by intraperitoneal injection of 4.25% peritoneal dialysis fluid (100 mL/kg). The epithelial-mesenchymal transition (EMT) of HMrSV5 cells was induced by the addition of 10 ng/mL transforming growth factor β (TGF-β). The differentially expressed genes in HMrSV5 cells treated with AS-IV were screened using transcriptome sequencing analysis. The potential targets of AS-IV were screened using network pharmacology and analyzed using molecular docking and molecular dynamics simulations.
RESULTS:
Administration of AS-IV at doses of 20, 40, or 80 mg/kg effectively mitigated the increase in peritoneal thickness and the development of fibrosis in mice with PF. The expression of the fibrosis marker α-smooth muscle actin in the peritoneum was significantly decreased in AS-IV-treated mice. The treatment of AS-IV (10, 20, and 40 μmol/L) significantly delayed the EMT of HMrSV5 cells induced by TGF-β, as demonstrated by the decreased number of 5-ethynyl-2'-deoxyuridine-positive cells, reduced migrated area, and decreased expression of fibrosis markers. A total of 460 differentially expressed genes were detected in AS-IV-treated HMrSV5 cells through transcriptome sequencing, with notable enrichment in the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)-AKT serine/threonine kinase 1 (AKT) signaling pathway. The reduced levels of phosphorylated PI3K (p-PI3K) and p-AKT were detected in HMrSV5 cells with AS-IV treatment. Epidermal growth factor receptor (EGFR) was predicted as a direct target of AS-IV, exhibiting strong hydrogen bond interactions. The activation of the PI3K-AKT pathway by the compound 740Y-P, and the activation of the EGFR pathway by NSC 228155 each partially counteracted the inhibitory effect of AS-IV on the EMT of HMrSV5 cells.
CONCLUSION
AS-IV delayed the EMT process in peritoneal mesothelial cells and slowed the progression of PF, potentially serving as a therapeutic agent for the early prevention and treatment of PF.

Objective To investigate the impact of risk prevention and control on the quality efficiency of medical equipment procurement.Methods The medical equipment procurement projects with enhanced risk prevention measures during 2023(119 items)were assigned to an observation group,while those without strengthened risk control during 2022(118 items)were enrolled into a control group.The two groups were compared in terms of bid failure/rejection rates,procurement completion cycles(including procurement execution cycle and total procurement cycle)and procurement satisfaction.Statistical analysis was performed using SPSS 20.0 software.Results The observation group demonstrated significantly lower bid failure/rejection rates when compared with the control group(≥2 occurrences:5.88%vs.15.25%,P<0.05).The procurement execution cycle was notably shorter in the observation group((69.16±78.65)d vs.(97.67±49.84)d,P<0.05),though no significant difference was observed in total procurement cycle(P>0.05).The observation group behaved better significantly than the control group in procurement efficiency,equipment performance,procedural compliance and post-purchase service satisfaction(all P<0.05).Conclusion Risk prevention and control measures in medical equipment procurement effectively reduce bid failure/rejection risks while enhancing procurement quality efficiency.[Chinese Medical Equipment Journal,2025,46(3):81-85]
