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.

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 Zinc finger protein 335 (Zfp335) plays a crucial role in the early development of thymic T cells and the differentiation of peripheral T cell subpopulations. The objective of this study is to investigate the role and underlying mechanisms of Zfp335 in the regulation of regulatory T cell (Treg) within tumor immunity. Methods The Zfp335 gene was specifically knocked out in Treg using tamoxifen (Zfp335fl/fl FOXP3creERT2), and the MC38 tumor model was established. On the 7th day after tumor inoculation, tumor size was observed and measured. Tumor size was monitored and recorded daily starting from day 7 post-inoculation. On day 12, tumors were harvested, and the proportions of CD4+ T cells, CD8+ T cells, and Treg were analyzed by flow cytometry. Additionally, the mitochondrial function of effector regulatory T cell (eTreg) was assessed. Results From day 10 post-tumor inoculation, tumor volume in the Zfp335CKO group was significantly reduced compared to that of the wild-type (WT) group. Furthermore, the infiltration of CD4+ and CD8+ T cells, along with their respective effector cells, was significantly higher in the Zfp335CKO group than in the WT group. The proportions of CD4+ and CD8+ T cells producing interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α) were also significantly increased in the Zfp335CKO group compared to that of the WT group. In addition, the percentage of CD8+ T cells secreting granzyme B (GzmB) was significantly higher in the Zfp335CKO group than that in the WT group. In contrast, the proportion of Treg and inducible T cell co-stimulator (ICOS)+ Treg in the Zfp335CKO group was significantly lower than that in the WT group. Finally, the expression level of Mitotracker Deep Red in eTreg from the Zfp335CKO group was significantly reduced compared to that in the WT group. Conclusion During tumorigenesis, the specific deletion of Zfp335 impairs Treg activation, which is related to decreased mitochondrial function in eTreg. In Zfp335CKO mice. Tumors exhibit increased infiltration of effector T cells, accompanied by elevated levels of cytotoxic cytokines, ultimately enhancing resistance to tumor progression.

OBJECTIVE:
To explore the effects of different endotracheal tube cuff pressure management modes on cuff sealing and the pressure exerted on the tracheal wall.
METHODS:
A prospective self-controlled study was conducted. Eleven patients undergoing endotracheal intubation and mechanical ventilation with an automatic airway management system (AGs) admitted to the Second Medical Centre of the Chinese People's Liberation Army General Hospital from October 1, 2020, to April 1, 2022, were enrolled as the study subjects. Within 24 hours after the establishment of artificial airway and mechanical ventilation, four cuff pressure management modes were randomly applied to each patient for 24 hours in sequence: automatic cuff pressure management mode [modeI: the safe range of cuff pressure was set at 20-35 cmH2O (1 cmH2O≈0.098 kPa), and the CO2 pressure above the endotracheal tube cuff was automatically detected by AGs every 5 minutes to determine the cuff sealing status, and the cuff pressure was automatically adjusted], constant cuff pressure (25 cmH2O) management mode (mode II: the cuff pressure was monitored by AGs through a pressure sensor, and the cuff pressure was maintained at 25 cmH2O via a pressure pump), constant cuff pressure (30 cmH2O) management mode (mode III: the cuff pressure was monitored by AGs through a pressure sensor, and the cuff pressure was maintained at 30 cmH2O via a pressure pump), and manual cuff pressure management mode (mode IV: the cuff pressure was manually measured by nurses every 6-8 hours using a cuff pressure gauge to keep the cuff pressure at 25-30 cmH2O after inflation). The CO2 pressure above the endotracheal tube cuff (at 60-minute intervals) and the cuff pressure changes (at 50-ms intervals) were recorded to compare the differences in number of cuff leaks [no leak was defined as CO2 pressure = 0, small leak as 0 < CO2 pressure < 2 mmHg (1 mmHg≈0.133 kPa), and large leak as CO2 pressure ≥ 2 mmHg] and cuff pressure among modesI-IV.
RESULTS:
A total of 24 CO2 pressure measurements were taken per patient across the four modes, resulting in a total of 264 detections for each mode. Regarding the cuff leak, the total number of leak and large leak in modeIwas significantly lower than that in modes II-IV [total leak: 30 cases (11.36%) vs. 81 cases (30.68%), 70 cases (26.52%), 103 cases (39.02%); large leak: 15 cases (5.68%) vs. 50 cases (18.94%), 48 cases (18.18%), 66 cases (25.00%), all P < 0.05]. There was no significant difference in the number of cuff leak between modes II and III, and mode IV had the most severe cuff leak. In terms of cuff pressure, since mode IV required blocking the cuff tube from the AGs tube and the AGs cuff pressure management module did not actually work, real-time monitoring of cuff pressure was not possible. Therefore, cuff pressure changes were only analyzed in modes I-III. Each of the 11 patients underwent 24-hour cuff pressure monitoring under modes I-III, with 19 008 000 monitoring times for each mode. The cuff pressure in mode I was between that in modes II and III [cmH2O: 27.09 (26.10, 28.14) vs. 26.60 (25.92, 27.47), 31.01 (30.33, 31.88), both P < 0.01]. Moreover, the number of extreme values of cuff pressure > 50 cmH2O in mode I was significantly lower than that in modes II and III [19 900 cases (0.105%) vs. 22 297 cases (0.117%), 27 618 cases (0.145%), both P < 0.05].
CONCLUSION
Dynamically monitoring the CO2 pressure above the cuff to guide the adjustment of endotracheal tube cuff pressure can achieve better cuff sealing with a relatively lower cuff pressure load.
