Prostate cancer is a prevalent malignant tumor of the male genitourinary system in China, with a persistently elevated incidence rate.Given the insidious onset, propensity for metastasis in advanced stages, and poor efficacy of traditional treatments, new hormone therapies have garnered increasing attention in recent years.A number of clinical studies have demonstrated that second-generation androgen receptor inhibitors (SGARIs), including enzalutamide, apalutamide, darolutamide, and rezvilutamide, can be beneficial in different stages of advanced prostate cancer.Furthermore, their early application has been shown to delay disease progression while maintaining a controlled safety profile.At present, SGARIs have increasingly become the primary therapeutic agents for advanced prostate cancer in various stages.This article reviews the clinical research progress of SGARIs in recent years, with the aim of offering valuable clinical reference for clinicians.

Xuefu zhuyu decoction is a classic formula for promoting blood circulation and resolving blood stasis， characterised by its remarkable ability to treat different diseases with the same approach. Qi stagnation and blood stasis， the primary syndrome for which this formula is indicated， has been found through modern medical research to be intrinsically linked to a wide range of pathophysiological processes， including microcirculatory disorders， abnormalities in hemorheology， inflammatory responses and endothelial dysfunction； which opens up vast scope for the innovative application of traditional formulas. In terms of pharmacological effect and mechanism， the formula exerts a synergistic regulatory effect across multiple key pathological pathways， including the regulation of coagulation function， the maintenance of vascular structure and function， anti-inflammatory and immunomodulatory actions， the mitigation of oxidative stress， and the modulation of programmed cell death （such as pyroptosis and ferroptosis）. This systematically demonstrates its scientific rationale， which is based on integrated regulation through multiple constituents， multiple targets and multiple pathways. In terms of clinical application， the formula has expanded from cardiovascular diseases to multiple disciplines， including gastroenterology， respiratory medicine， urology， neurology， endocrinology， gynaecology and andrology， with evidence-based medical evidence continuing to accumulate. Current research still faces bottlenecks such as a relatively low level of clinical evidence， insufficient systems biology analysis of the mechanisms underlying the compound’s formulation， and a weak correlation between quality control indicators and therapeutic efficacy. Future efforts should focus on conducting multicentre randomised controlled trials for conditions where the formula demonstrates particular efficacy， deepening research into the relationship between integrated pharmacology and spectrum-efficacy relationship， and promoting the precise application and formulation innovation of classical herbal formulas.

Objective To understand the membrane protein molecular epidemiology of carbapenem-resistant Pseudomonas aeruginosa (CRPA) in the region,and provide some evidence for rational drug use or application of efflux pump inhibitors. Methods Collected Pseudomonas aeruginosa isolated from four hospitals in the region from October 2022 to August 2023,and used SYBR-PCR method to quantitatively detect the relative mRNA expression (RE) levels of 10 membrane protein coding genes,including mexA,B,C,D,E,F,X,Y,and oprD,M. Then categorized the strains into five groups based on ceftazidime,cefepime,imipenem,and meropenem resistance phenotype combination,including the compassionate group (Group Ⅰ),Group Ⅱ with full resistance,IPM,MEM resistant,CAZ and CFP sensitive groups (Group Ⅲ),IPM resistance,MEM non-resistance (sensitive or intermediate) group (Group Ⅳ),IPM,MEM resistance,CAZ and CFP non-resistance groups (Group V).The median RE of each membrane protein-coding gene was analyzed. Results A total of 108 strains of Pseudomonas aeruginosa were collected,with 24 strains in Group Ⅰ as controls and 84 strains in the carbapenem resistant group,including 32 strains in Group Ⅱ,22 strains in Group Ⅲ,13 strains in Group Ⅳ,and 17 strains in Group Ⅴ. The expression of mexD,mexE,mexF,mexX and mexY in the drug-resistant group was higher than that in the control group,and the differences were statistically significant (U=409.5～661.0,all P<0.05). There was no statistically significant difference in mexA,mexB,mexC,oprD and oprM with the control group (U=767.0～1004.5,all P>0.05). There was no significant difference in the expression of RE genes encoding various membrane proteins among strains from different hospitals (H=0.914～7.407,all P>0.05). Among the four different phenotypes,there was no statistically significant difference in the irregular distribution of mexA and oprM RE between each group and the control group (UmexA=95.0～264.0,UoprM=143.0～331.0). The mexC RE in each group was lower than that in the control group,but the differences were not statistically significant (U=134.0～344.5,all P>0.05). MeixE and meixY RE were both higher than the control group,and the differences were statistically significant (UmexE=48.0～230.0,UmexY=83.0～184.0). MeixB was lower than the control group in group Ⅳ (U=72.0),and the differences were statistically significant (all P<0.05). MeixD and meixF showed consistent expression,with higher expression in groups Ⅲ,Ⅳ and Ⅴ compared to the control group (UmeixD=34.0～102.0,UmeixF=65.0～113.0). MeixX was expressed higher in groups Ⅱ,Ⅳ and Ⅴ compared to the control group (U=164.0,58.0,111.0),while oprD was only expressed lower in group Ⅲ than in the control group (U=140.0),with statistically significant differences (all P<0.05). Although the expression of oprD in groups Ⅱ,Ⅳ and Ⅴ was lower than that in the control group,the differences were not statistically significant (U=381.0,102.0,144.0,all P>0.05). Conclusion ExCD,mexEF and mexXY are the main membrane protein combinations of CRPA efflux pumps in Kunming area. Upregulation of mexD,E,F,X,and Y membrane protein expression enhanced efflux. The correlation between mexAB oprM efflux pump and carbapenem resistance in CRPA in this area was low. The low expression of oprD played a role in the efflux mechanism in strains that do not produce β-lactase,but there was no significant difference in low expression in enzyme producing strains.

Objective:To evaluate the efficacy and feasibility of a domestically developed robotic surgical system based on fiber-optic dedicated line communication in cross-regional urological telesurgery.Methods:This was multicenter，single-arm，retrospective case series study. The data of patients who underwent urological telesurgeries using the telesurgical system between January 2023 and December 2024 were analyzed. The cohort included 59 patients from seven hospitals across China. Among the patients，47 were male（79.7%）and 12 were female（20.3%），with a median age of 63.0（56.0，68.0）years and a body mass index of（24.7 ± 3.0）kg/m 2. Surgical procedures included 32 radical prostatectomies，24 partial nephrectomies，one radical nephrectomy，one adrenalectomy，and one ureteral reconstruction. The perioperative indicators，pathological results and postoperative complications were analyzed. The network monitoring data were collected，and the perioperative data of patients，remote system monitoring data and costs were compared between the two communication modes of optical transport network（OTN）and cloud-connect network（CCN）. Results:All 59 remote surgeries were successfully completed，with a mean operative time of（138.0 ± 54.0）minutes，median intraoperative blood loss of 50.0（30.0，100.0）ml and a postoperative hospital stay of 5.0（4.0，6.0）days. No cases required reoperation，Clavien-Dindo grade ≥3 complications，or readmission. The geographical distance between the primary and remote surgical sites ranged from 450 to 2 800 km. Network monitoring revealed increased bidirectional latency with distance increasing：the shortest latency time（Hefei-Hangzhou，450 km）was（16.59 ± 0.80）ms，while the longest（Harbin-Hangzhou，2 200 km）latency time was（53.31 ± 0.31）ms. Average frame loss per procedure was 0?1.27 frames. The results of subgroup analysis comparing OTN and CCN communication modes showed no significant differences in operative time［（130.7 ± 70.5）minutes vs.（142.1 ± 42.9）minutes， P = 0.442］，postoperative hospitalization［6.0（4.0，8.0）d vs. 5.0（4.0，6.0）d， P = 0.581］，or readmission rates（0 vs. 0）. However，CCN demonstrated significant cost advantages with 500 RMB per operation vs. 3 000 RMB per operation for OTN. Conclusions:Urological telesurgery using fiber-optic communication is feasible. The CCN mode，with its cost-effectiveness，excellent usability，and multi-point interconnection flexibility，is currently the preferred communication model for telesurgical applications.

Objective:To investigate the value of biparametric-MRI (bpMRI) based peritumoral radiomics for preoperative prediction of extraprostatic extension (EPE) in prostate cancer (PCa).Methods:In this cross-sectional study, consecutive bpMRI of patients undergoing prostatectomy for PCa were retrospectively collected from the First Medical Center (center 1) and the Third Medical Center (center 2) of Chinese PLA General Hospital. A total of 274 patients were finally enrolled. Patients at center 1 from January 2020 to December 2022 were randomly divided into a training set (149 cases) and an internal validation set (63 cases) by stratified random sampling. Patients at center 2 from January 2023 to March 2024 were assigned to the external test set (62 cases). Patients were categorized into EPE-positive group and EPE-negative group according to pathological assessment postoperatively. In the training set, there were 49 cases in EPE-positive group and 100 cases in EPE-negative group. In the internal validation set, there were 26 cases in EPE-positive group and 37 cases in EPE-negative group. In the external test set, there were 22 cases in EPE-positive group and 40 cases in EPE-negative group. Axial T 2WI and apparent diffusion coefficient (ADC) images were manually annotated to obtain index lesion regions of interest (ROIs), with the peritumoral ROIs subsequently delineated by semi-automatic segmentation technique. Radiomics features were extracted from intra-tumoral, peri-tumoral, and intra-tumoral plus peri-tumoral ROIs. The training set data was employed to select and optimize features to build the radiomics models. The logistic regression analysis was used to develop radiomics, clinical, and integrated models. The predictive performance was assessed by the area under the receiver operating characteristic curve (AUC) in the external test set, and compared by the DeLong test. The sensitivity and specificity were compared by the exact McNemar test. Results:In the external test set, the peri-tumoral radiomics model based on bpMRI showed the highest performance in evaluating EPE, with an AUC of 0.739 (95% CI 0.611-0.842), which was identified as the optimal radiomics model. EPE grade ( OR=6.151, 95% CI 3.371-11.226, P<0.001) was incorporated into the clinical model, with an AUC of 0.780 (95% CI 0.657-0.875) in the external test set. The integrated model had an AUC of 0.817 (95% CI 0.698-0.904) in the external test set. There was no statistically significant difference in comparisons of AUCs among the three models (all P>0.05). The sensitivity of the integrated model (68.2%) showed no significant difference from those of the clinical model and the optimal radiomics model (77.3% and 86.4%, respectively; P=0.500 and P=0.289). However, the specificity of the integrated model (85.0%) was significantly higher than those of the clinical model (67.5%, P=0.016) and the optimal radiomics model (50.0%, P<0.001). Conclusion:A bpMRI-based peritumoral radiomics integrating clinical model demonstrates high performance for preoperative prediction of EPE in PCa.

Objective To explore the mechanism of butylphthalide(NBP)in regulating microglia acti-vation and inflammatory cytokine expression in the hippocampus of the mouse model of delayed encephalopathy af-ter carbon monoxide poisoning(DEACMP).Methods Wild-type C57 adult mice with normal cognitive function were selected,and DEACMP was modeled by static inhalation of carbon monoxide.The mice were randomized in-to three groups:DEACMP,control,and NBP.The NBP group was administrated with NBP suspension at 6 mg/kg by gavage for 21 days,and the DEACMP and control groups were administrated with the same amount of vegeta-ble oil by gavage.The hippocampal injury was observed by HE staining.The protein level of ionized calcium-bind-ing adapter molecule 1(IBA1)was determined by Western blotting,and the levels of downstream inflammatory cytokines were measured by ELISA.Results Compared with the control group,the DEACMP and NBP groups showed prolonged escape latency(P=0.001,P=0.029),reduced nerve cells(P=0.001,P=0.035),up-regulated expression of IBA1(P=0.001,P=0.042),increased mean fluorescence intensity of IBA1(P=0.001,P=0.021),and elevated levels of tumor necrosis factor-α(TNF-α)(P=0.002,P=0.024),inter-leukin(IL)-6(P=0.001,P=0.015),and IL-1β(P=0.001,P=0.023).Compared with the DEACMP group,the NBP group showed shortened escape latency(P=0.025),increased nerve cells(P=0.039),down-regulated expression of IBA1(P=0.035),decreased average fluorescence intensity of IBA1(P=0.031),and lowered levels of TNF-α(P=0.028),IL-6(P=0.037),and IL-1 β(P=0.034).Conclusion NBP can inhibit the activation of microglia and reduce the expression of inflammatory factors,thereby alleviating cog-nitive dysfunction and brain tissue damage caused by DEACMP.
