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 explore the mechanisms of Qianlie Jindan Tablets(QLJD)acting on chronic nonbacterial prostatitis(CNP)in rats based on non-targeted urine metabolomics.Methods:According to the body mass index,we equally randomized 30 eight-week-old male SD rats into a blank control,a CNP model control and a QLJD medication group.We established the CNP model in the latter groups and,from the 4th day of modeling,treated the rats in the blank and model control groups intragastrically with nor-mal saline and those in the QLJD medication group with QLJD suspension,qd,for 30 successive days.Then we detected the changes in the metabolites of the rats by ultra-high-performance liquid chromatography-tandem mass spectrometry,and identified the differential metabolites in different groups by multivariate statistical analysis,followed by functional annotation of the differential metabolites.Results:Eight common metabolites were identified by metabolomics analysis,of which 5 were decreased in the CNP model controls and increased in the QLJD medication group,while the other 3 increased in the former and decreased in the latter group.Creatinine and genistein were important differential metabolites,and the arginine and proline metabolic pathways and isoflavone biosynthesis pathways were the main ones for QLJD acting on CNP.Compared with the blank controls,the model controls showed up-regulated arginine and proline metabolic pathways,increased production of creatinine,down-regulated isoflavone biosynthetic pathway and decreased produc-tion of genistein.The above changes in the model controls were all reversed in the QLJD medication group.Conclusion:QLJD acts effectively on CNP in male rats by regulating L-arginine and proline metabolic pathways,as well as the isoflavone biosynthesis pathway and naringenin metabolism.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.

【Objective】 Thrombelastogram(TEG) was used to detect the blood clotting function of patients with esophageal cancer in each stage of perioperative period, so as to understand the change pattern of blood clotting function in patients with esophageal cancer during perioperative period, and to guide the postoperative anticoagulation or hemostasis treatment. 【Methods】 Sixty patients diagnosed with esophageal cancer who underwent surgical treatment between May 2017 and May 2019 in Jiangmen Central Hospital were selected as the experimental group, and 60 cases of healthy physical examination were selected as the normal control group. By contrasting with the normal control group, results of blood sample testing for the experimental group 1 day before, 1 day after operation, and the 7th day postoperative thrombosis elastic figure were used to analyze the change of the esophageal perioperative blood coagulation function. 【Results】 Compared with the control group before surgery, the TEG parameters R, K and LY30 decreased, and Angle, MA and CI increased, with statistically significant differences(P < 0.05). Compared with the normal control group after surgery, the R and K values of TEG parameters in the experimental group decreased significantly, while Angle, MA and CI values increased significantly, with statistically significant differences(P < 0.01), and LY30 values decreased, with statistically significant differences(P < 0.05). Compared with the experimental group before and after surgery, the TEG parameters R and K decreased, and the values of LY30, Angle, MA and CI increased, with no statistically significant difference(P > 0.05). Seven days after the operation and 1 day after the operation, the values of R and K of TEG decreased, and the values of MA and CI increased, with statistically significant differences(P < 0.05) . 【Conclusion】 All patients with esophageal cancer presented hypercoagulability before and after operation.Surgery and anesthesia did not significantly change the coagulation status of esophageal cancer. In the postoperative recovery process, the hypercoagulable state will be more obvious.

Along with the extensive application of intervention in treating coronary heart disease (CHD), problems such as post-interventional restenosis, no reflowing, and slow flowing, and so on increasingly emerge. Chinese medicine and pharmacy occupy advantages covering preventing post-intervention risk factors, improving and relieving patients' symptoms, and so on. It is a good support and supplement for routine therapies in modern medicine. Taking the pathological stages of CHD and clinical problems of coronary intervention as the breakthrough points, the Chinese medical syndromes and correspondent Chinese medicine recipes and herbs were preliminarily studied by combining Chinese medicine's recognition and clinical observation on coronary intervention.

OBJECTIVETo analyze the efficacy and quality of life and safety for paclitaxel and carboplatin (TC) and TC combined with endostar in the treatment of advanced non-small cell lung cancer (NSCLC).

METHODSThis is a prospective, multicenter, randomized, double-blind, placebo-controlled clinical study. A total of 126 cases of untreated advanced NSCLC were enrolled in this study. There were 63 patients in the TC control arm and TC combined endostar arm, respectively. All enrolled patients were continuously followed-up for disease progression and death.

RESULTSThe objective response rate (ORR) of TC combined with endostar arm was 39.3%, and that of TC control arm was 23.0%, P = 0.078. The progression-free survival rates for TC combined with endostar arm and TC control arm were 78.3% and 58.8%, respectively, in 24 weeks (P = 0.017). The hazard ratio for the risk of disease progression was 0.35 (95%CI 0.13 to 0.90, P = 0.030). The median time to progression (TTP) of the TC combined with endostar arm was 7.1 months and TC arm 6.3 months (P > 0.05). The follow-up results showed that the median survival time (mOS) of the TC + Endostar arm was 17.6 months; (95%CI 13.4 to 21.7 months), and the TC + placebo arm 15.8 months (95%CI 9.4 to 22.9 months) (P > 0.05). The quality of life scores (LCSS patient scale) after treatment of the TC combined with endostar arm was improved, and that of the TC group was improved after completion of two cycles and three cycles of treatment. The quality of life scores compared with baseline after the completion of one cycle treatment was significantly improved for both the TC combined with endostar arm (P = 0.028 and), and TC arm (P = 0.036). It Indicated that TC combined with endostar treatment improved the patient's quality of life in the early treatment. The difference of adverse and serious adverse event rates between the two groups was not significant (P > 0.05).

CONCLUSIONSCompared with TC alone treatmrnt, TC combined with endostar treatment can reduce the risk of disease progression at early time (24 weeks), increase the ORR, and can be used as first-line treatment for advanced NSCLC. The TC combined with endostar treatment has good safety and tolerability, improves the quality of life, and not increases serious adverse effects and toxicity for patients with advanced NSCLC.

OBJECTIVETo review tension-free repairing for the patients with inguinal hernia complicated with cirrhosis and ascites.

METHODSTension-free herniorrhaphy was performed in 16 cases with inguinal hernia complicated with cirrhosis and ascites from November 1999 to November 2003. The laboratory data before and after the operation were compared and analyzed in this group.

RESULTSOf the patients, 13 cases were male and 3 were female, the mean age was (64 ± 12) years (range, 37 - 85 years). The liver function was classified as A degree in 4 case, B degree in 10 cases and C degree in 2 patients by using Child score. The operation was successfully carried out in all patients without complications and post-operative hepatoencephalopathy. There was no significant change in the plasma total protein, bilirubin, prothrombin activity and international normalized ratio (INR) after the operation. And the levels of albumin, globulin and white blood cell count changed remarkably after the operation (all P < 0.05). Plasma albumin level was obviously effected by the operation and treatment (P = 0.006). The mean follow-up time was 72.5 months (57 - 102 months). No recurrence occurred during the follow-up. There was no patient died in 30 days after the operation. Seven cases (43.8%) died in the later period of follow-up.

CONCLUSIONSThe tension-free repairing is feasible for the inguinal hernia complicated with cirrhosis and ascites. More attention should be paid to the level of plasma albumin and it should be corrected in time. The liver cirrhosis and its complications will progress after the operation with a poor prognosis.
