Objective To understand the distribution and changing resistance profiles of clinical isolates of Enterococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Enterococcus according to the unified protocol of CHINET program by automated systems,Kirby-Bauer method,or E-test strip.The results were interpreted according to the Clinical & Laboratory Standards Institute(CLSI)breakpoints in 2021.WHONET 5.6 software was used for statistical analysis.Results A total of 124 565 strains of Enterococcus were isolated during the 7-year period,mainly including Enterococcus faecalis(50.7％)and Enterococcus faecalis(41.5％).The strains were mainly isolated from urinary tract specimens(46.9％±2.6％),and primarily from the patients in the department of internal medicine,surgery and ICU.E.faecium and E.faecalis strains showed low level resistance rate to vancomycin,teicoplanin and linezolid(≤3.6％).The prevalence of vancomycin-resistant E.faecalis and E.faecium was 0.1％and 1.3％,respectively.The prevalence of linezolid-resistant E.faecalis increased from 0.7％in 2015 to 3.4％in 2021,while the prevalence of linezolid-resistant E.faecium was 0.3％.Conclusions The clinical isolates of Enterococcus were still highly susceptible to vancomycin,teicoplanin,and linezolid,evidenced by a low resistance rate.However,the prevalence of linezolid-resistant E.faecalis was increasing during the 7-year period.It is necessary to strengthen antimicrobial resistance surveillance to effectively identify the emergence of antibiotic-resistant bacteria and curb the spread of resistant pathogens.

Objective:To explore the early clinical efficacy of ultrasound visualized platelet-rich plasma (PRP) in the treatment of lower back myofascial pain syndrome (MPS) after sports injury.Methods:A prospective cohort study was conducted to analyze the clinical data of 32 patients with lower back MPS after sports injury, who were admitted to West China Hospital of Sichuan University from January 2023 to March 2023. Ultrasound-guided PRP injection into the erector spinalis or quadratus psoas muscles was used for treatment. Before treatment, at 24 hours, 2 weeks, and 4 weeks after treatment, pain and function were evaluated using visual analogue scale (VAS), McGill pain questionnaire (McGill), Roland Morris dysfunction questionnaire (RMDQ), and Oswestry dysfunction index (ODI). Before treatment and 4 weeks after treatment, the quality of life was evaluated using the short-form 36 item health survey questionnaire (SF-36). The adverse reactions were observed during treatment and follow-up.Results:A total of 32 patients with lower back MPS after sports injury were enrolled, including 10 males and 22 females; aged 12-68 years [(47.3±16.3)years]. All the patients were followed up for 4 weeks. Before and at 24 hours, 2 weeks, and 4 weeks after treatment, the VAS was 5.0(4.0, 6.0)points, 3.5(3.0, 4.8)points, 2.0(2.0, 3.0)points, and 2.0(1.3, 3.0)points, respectively; the McGill score was 9.0(7.0, 11.0)points, 7.0(5.0, 9.0)points, 4.0(3.0, 5.0)points, and 3.0(3.0, 5.0)points, respectively; the RMDQ score was 8.0(5.3, 10.8)points, 5.5(3.0, 8.0)points, 4.0(3.0, 5.8)points, and 3.0(2.0, 4.8)points, respectively; the ODI was 22.0(14.5, 30.0), 20.0(14.5, 25.5), 9.0(6.0, 16.0), and 8.0(4.5, 14.0), respectively. Compared with the values before treatment, the VAS, McGill score, and RMDQ score were significantly decreased at 24 hours, 2 weeks, and 4 weeks after treatment (all P<0.05); the ODI had no significant difference at 24 hours after treatment ( P>0.05), but it was significantly decreased at 2 and 4 weeks after treatment (all P<0.05). Compared with the values at 24 hours after treatment, the VAS, McGill score, RMDQ score and ODI further decreased at 2 weeks after treatment (all P<0.05). Compared with the values at 2 weeks after treatment, there was no significant difference in the VAS, McGill score, RMDQ score, or ODI at 4 weeks after treatment (all P>0.05). In the SF-36, the scores of physiological function [77.5(60.0, 93.8)points], physiological role [50.0(0.0, 100.0)points], body pain [64.0(44.5, 74.0)points], vitality [75.0(65.0, 78.8)points], social function [87.5(75.0, 100.0)points], emotional role [66.7(33.3, 100.0)points] and mental health [72.0(68.0, 83.0)points] before treatment were increased to 90.0(80.0, 98.8)points, 100.0(56.3, 100.0)points, 84.0(74.0, 84.0)points, 75.0(70.0, 80.0)points, 100.0(87.5, 112.5)points, 100.0(66.7, 100.0)points, and 76.0(68.0, 84.0)points after 4 weeks of treatment, respectively ( P<0.05 or 0.01). However, there was no significant difference in the general health status or health changes before and after treatment (all P>0.05). During treatment and follow-up, no adverse reactions such as redness, swelling, pain, or subcutaneous bleeding were observed. Conclusion:Ultrasound-guided PRP treatment can improve the early pain, lumbar mobility and quality of life of patients with lower back MPS after sports injury, with no presence of adverse reactions.

BACKGROUND: It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011. METHODS: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided). RESULTS: The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107). CONCLUSIONS: The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly. TRIAL REGISTRATION NUMBER NCT03620565, https://register.clinicaltrials.gov.

OBJECTIVE: To investigate the current status of antibiotic use for very and extremely low birth weight (VLBW/ELBW) infants in neonatal intensive care units (NICUs) of Hunan Province. METHODS: The use of antibiotics was investigated in multiple level 3 NICUs of Hunan Province for VLBW and ELBW infants born between January, 2017 and December, 2017. RESULTS: The clinical data of 1 442 VLBW/ELBW infants were collected from 24 NICUs in 2017. The median antibiotic use duration was 17 days (range: 0-86 days), accounting for 53.0% of the total length of hospital stay. The highest duration of antibiotic use was up to 91.4% of the total length of hospital stay, with the lowest at 14.6%. In 16 out of 24 NICUs, the antibiotic use duration was accounted for more than 50.0% of the hospitalization days. There were 113 cases with positive bacterial culture grown in blood or cerebrospinal fluid, making the positive rate of overall bacterial culture as 7.84%. The positive rate of bacterial culture in different NICUs was significantly different from 0% to 14.9%. The common isolated bacterial pathogens Klebsiella pneumoniae was 29 cases (25.7%); Escherichia coli 12 cases (10.6%); Staphylococcus aureus 3 cases (2.7%). The most commonly used antibiotics were third-generation of cephalosporins, accounting for 41.00% of the total antibiotics, followed by penicillins, accounting for 32.10%, and followed by carbapenems, accounting for 13.15%. The proportion of antibiotic use time was negatively correlated with birth weight Z-score and the change in weight Z-score between birth and hospital discharge (r=-0.095, -0.151 respectively, P<0.01), positively correlated with death/withdrawal of care (r=0.196, P<0.01). CONCLUSIONS Antibiotics used for VLBW/ELBW infants in NICUs of Hunan Province are obviously prolonged in many NICUs. The proportion of routine use of third-generation of cephalosporins and carbapenems antibiotics is high among the NICUs.

OBJECTIVE: To evaluate the satisfaction and performance of water colonoscopy and gas colonoscopy. METHODS: 240 continuous cases were randomly divided into two groups(gas colonoscopy group, water colonoscopy group). Record the general condition, success rate, period of performance and abdominal pain score. Investigate the degree of abdominal pain, distension and the will of receiving anesthetic colonoscopy next time in the follow-up. RESULTS: There were no significant difference between two groups in the general condition, success rate, depth of insertion, abdominal pain after examination or the will of receiving anesthetic colonoscopy next time(P>0.05). The period of insertion, period of withdrawal and period of performance in water colonoscopy group was longer than those in the gas colonoscopy group(P<0.001, P=0.013, P<0.001). The degree of abdominal distension at 1 hour after colonoscopy in water colonoscopy group was higher than those in the gas colonoscopy group(P<0.001), but no significant difference was found at6 hours after examination. CONCLUSION: Patients undergoing water colonoscopy have better outcomes with less abdominal pain and abdominal distension except for longer time of performance.

OBJECTIVETo evaluate the effect and safety of Kuanxiong Aerosol (, KA) on patients with angina pectoris.

METHODSBlock randomization was performed to randomly allocate 750 patients into KA (376 cases) and control groups (374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA (0.6 mL per spray). The control group received 1 sublingual nitroglycerin tablet (NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment (1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors inflfluencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society (CCS) classes of angina.

RESULTSThe 5-min remission rates in the KA and control groups were not signifificantly different (94.41% vs. 90.64%, P>0.05). The angina CCS class signifificantly inflfluenced the rate of remission (95% confidence interval = 0.483-0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSII and III subgroups (P>0.05), while they were signifificantly better for KA in the CCSI and II subgroups (P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was signifificantly lower in the KA group than in the control group for the CCSII and III subgroups (9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01).

CONCLUSIONSKA is not inferior to NT in the remission of angina. Furthermore, in CCSII and III patients, KA is superior to NT, with a lower incidence of adverse reactions. (Registration No. ChiCTRIPR-15007204).

Background: Automated peritoneal dialysis (APD) can cater to individual needs, provide treatment while asleep, take into account the adequacy of dialysis, and improve the quality of life. Currently, independent research and development of APD machines made in China are more conducive to patients. A randomized, multicenter, crossover study was conducted by comparing an APD machine made in China with an imported machine. The safety, effectiveness, and manipulability of the two machines were compared. Methods: Two hundred and sixty patients who underwent peritoneal dialysis (PD) on a regular basis in 18 centers between August 2015 and February 2016 were included. The inclusion criteria include age ≥18 years and PD ≥30 days. The exclusion criteria were as follows: hemodialysis; exit site or tunnel infection; and peritonitis ≤30 days. The patients were randomly divided into Group A, who were first treated with a FM machine made in China, then changed to an imported machine; and Group B, who were treated using the reverse sequence. APD treatment was performed with 10 L/10 h and 5 cycles of exchange. After 72 h, the daily peritoneal Kt/V, the accuracy of the injection rate, accuracy of the injection temperature, safety, and manipulability of the machine were assessed. Noninferiority test was conducted between the two groups. Results: The daily peritoneal Kt/V in the APD machine made in China and the imported APD machine were 0.17 (0.14, 0.25) and 0.16 (0.13, 0.23), respectively. There was no significant difference between the groups (Z = 0.15, P = 0.703). The lower limit of the daily Kt/V difference between the two groups was 0.0069, which was greater than the noninferiority value of -0.07 in this study. The accuracy of the injection rate and injection temperature was 89.7% and 91.5%, respectively, in the domestic APD machine, which were both slightly better than the accuracy rates of 84.0% and 86.8% in the imported APD machine (89.7% vs. 84.0%, P = 0.2466; 91.5% vs. 86.8%, P = 0.0954). Therefore, the APD machine made in China was not inferior to the imported APD machine. The fuselage of the imported APD machine was space-saving, while the APD machine made in China was superior with respect to body mobility, man-machine dialog operation, alarm control, and patient information recognition. Conclusions: The FM machine made in China was not inferior to the imported APD machine. In addition, the FM machine made in China had better operability.
