Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in healthcare facilities in major regions of China in 2023.Methods Clinical isolates collected from 73 hospitals across China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2023 Clinical & Laboratory Standards Institute (CLSI) breakpoints.Results A total of 445199 clinical isolates were collected in 2023,of which 29.0％ were gram-positive and 71.0％ were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species (excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi) (MRSA,MRSE and MRCNS) was 29.6％,81.9％ and 78.5％,respectively.Methicillin-resistant strains showed significantly higher resistance rates to most antimicrobial agents than methicillin-susceptible strains (MSSA,MSSE and MSCNS).Overall,92.9％ of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 91.4％ of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis had significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 93.1％ in the isolates from children and and 95.9％ in the isolates from adults.The resistance rate to carbapenems was lower than 15.0％ for most Enterobacterales species except for Klebsiella,22.5％ and 23.6％ of which were resistant to imipenem and meropenem,respectively .Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.6％ to 10.0％.The resistance rate to imipenem and meropenem was 21.9％ and 17.4％ for Pseudomonas aeruginosa,respectively,and 67.5％ and 68.1％ for Acinetobacter baumannii,respectively.Conclusions Increasing resistance to the commonly used antimicrobial agents is still observed in clinical bacterial isolates.However,the prevalence of important crabapenem-resistant organisms such as crabapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a slightly decreasing trend.This finding suggests that strengthening bacterial resistance surveillance and multidisciplinary linkage are important for preventing the occurrence and development of bacterial resistance.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To investigate the efficacy and safety of irreversible electroporation in focal ablation of localized prostate cancer.Methods:Clinical data of 128 patients with localized prostate cancer treated with irreversible electroporation from August 2019 to September 2023 at Renji Hospital of Shanghai Jiaotong University School of Medicine, Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology, and Dongfang Hospital of Tongji University, were retrospectively analyzed. The median age was 68 (62, 75) years. The median PSA was 8.64 (5.83, 12.57) ng/ml. Gleason score was 6 in 57 cases, 7 in 39 cases, and greater than 7 in 19 cases. There were 4 cases of T 1c, 69 cases of T 2a, 27 cases of T 2b, and 28 cases of T 2c. No lymph node or distant metastasis was seen in preoperative examination. All patients had no preoperative urinary retention or urinary incontinence. Irreversible electroporation treatment was administered under general anesthesia with patients in the lithotomy position. A transrectal ultrasound probe was used to measure prostate lesion size, determining the type and number of electrode needles. Electrode needles were strategically positioned around the targeted lesion. The distance between each pair of needles used for ablation ranged from 0.5 to 2.0 cm. The system automatically generated treatment parameters, including voltage, current, and the number of pulses, with each pulse cycle lasting approximately 5 minutes. After treatment, the needles were removed, gauze was applied for 1 minute. The urethra was then irrigated with a painless iodine solution diluted 1∶1 with 0.9% saline, followed by the insertion of a urinary catheter. Treatment efficacy and adverse reactions were documented. Biochemical recurrence was defined as a PSA increase of over 2 ng/ml from the post-treatment nadir; imaging recurrence was identified by abnormal lesions on MRI or contrast-enhanced ultrasound. Results:All 128 surgeries were successfully completed. At 6 months postoperatively, 116 cases were followed. Tne median PSA was 1.58 (0.56, .95) ng/ml, which was 82.22% (65.37%, 93.33%) lower than preoperative level( P<0.01). Five patients (4.31%) had biochemical recurrence, and MRI or contrast-enhanced ultrasound examinations were negative, 1 patient underwent radical prostatectomy with pathology of prostate cancer, and the remaining 4 were continued to be followed up. Ninety-eight patients underwent MRI or contrast-enhanced ultrasound review, including 6 patients (6.12%) detected imaging recurrence, of which 2 patients underwent radical prostatectomy with pathology of prostate cancer, and the remaining 4 underwent endocrine therapy. The postoperative continence rate was 98.28%, and 8 patients (6.89%) had complications of class II. Conclusions:Irreversible electroporation for focal treatment of localized prostate cancer has shown favorable results in terms of tumor control, safety and urinary continence.

Objective To investigate the effect of esketamine on depression and improvement of postoperative cognitive function in patients with major depressive disorder treated by electroconvulsive therapy(ECT).Methods A total of 115 patients with major depressive disorder,37 males and 78 fe-males,aged≥12 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ were selected to receive ECT.The patients were randomly divided into two groups using a random number table:the esketamine group(group E,n=56)and the control group(group C,n=59).Group E received esketamine,propofol,and succincholine during anesthesia induction,and group C received propofol and succincholine during an-esthesia induction.ECT indicators(including EEG twitch time,twitch time,stimulus intensity,and twitch energy index)were recorded during each ECT session.Montreal cognitive assessment(MoCA)and Mini-mental state examination(MMSE)were used to evaluate cognitive function at baseline and after ECT treat-ment.Hamilton depression(HAMD)scale was used to score depression.The occurrence of headache,nau-sea,vomiting,dizziness,delirium,and other adverse reactions were recorded.Results Compared with group C,the EEG convulsion time in group E was significantly prolonged(P＜0.05),the incidence of Mo-CA score decreased by≥1 point and MMSE score decreased by≥1 point in group E after the end of ECT treatment was significantly reduced(P＜0.05),the incidence of nausea,vomiting,and dizziness were sig-nificantly decreased(P＜0.05).Conclusion Using esketamine in ECT for the treatment of major depres-sive disorder can improve cognitive function after ECT.

Objective:To investigate the clinical outcomes of infertility patients with multiple morphological abnormalities of the sperm flagella (MMAF) caused by DNAH1 gene mutation after intracytoplasmic sperm injection (ICSI). Methods:A retrospective cohort study analyzed the clinical data and genetic test results of 39 MMAF infertility patients who were treated in the Center for Reproductive Medicine of Henan Provincial People's Hospital from February 2018 to January 2020. Twelve MMAF patients caused by DNAH1 mutations were acted as DNAH1 positive group and 27 MMAF patients with no DNAH1 mutations were acted as DNAH1 negative group. Totally 100 cases of infertility patients with normal sperm morphology and their spouses who were age-matched by both men and women for ICSI during the same period were selected as control group. The outcomes of assisted pregnancy treatment in the three groups were analyzed. Results:All 39 MMAF patients underwent whole-exome sequencing. Among them, 12 patients had DNAH1 gene mutations, 10 cases of compound heterozygous mutations and 2 cases of homozygous mutations, and the other 27 cases were not detected the currently known DNAH1 mutations. The patients of three groups were treated with ICSI, and the differences in the number of oocytes obtained and the number of M II oocytes in the DNAH1 gene positive group, DNAH1 gene negative group and control group were statistically significant (17.08±5.32, 9.59±3.98, 10.44±6.33, P=0.001; 14.58±5.18, 6.78±3.38, 8.32±5.31, P<0.001). There were no statistically significant differences in the embryo implantation rate, the clinical pregnancy rate, the embryo miscarriage rate and the live birth rate (all P>0.05). Among them, 12 couples of male infertility caused by DNAH1 mutation received a total of 12 cycles of oocyte extraction, forming 79 day 3 embryos, 12 times of the first fresh or frozen embryo transplantation, and 10 biological offspring were obtained. Conclusion:For patients with MMAF caused by DNAH1 gene mutation, ICSI can help them to give birth to their own offspring, and has a higher clinical pregnancy rate and live birth rate.
