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 application effect of multidisciplinary team (MDT) nursing model in enteral nutrition support for patients in intensive care unit (ICU) .Methods:The convenient sampling method was used to select 76 patients undergoing enteral nutrition in ICU of Taizhou Hospital in Zhejiang Province from August 2020 to August 2022 as the research objects. A total of 37 patients admitted from August 2020 to August 2021 were set as the control group, and 39 patients admitted from September 2021 to August 2022 were set as the intervention group. Patients in the control group received routine nursing, while patients in the intervention group received MDT nursing model. The start time of enteral nutrition after admission to ICU, the compliance rate of enteral nutrition at 7 days after feeding, the rate of feeding interruption and the incidence of complications were compared between the two groups.Results:After intervention, the start time of enteral nutrition after admission to ICU in the intervention group was shorter than that in the control group, the compliance rate of enteral nutrition at 7 days after feeding was higher than that in the control group, and the feeding interruption rate and incidence of aspiration, nausea, vomiting and diarrhea were lower than those in the control group ( P<0.05) . Conclusions:The MDT nursing model can improve the effect of enteral nutrition support for ICU patients and reduce the incidence of enteral nutrition complications.

Objective To explore the clinical value of endoscopic ultrasonography(EUS)combined with serum serine protease inhibitor Kazal 1(SPINK1)and secretory phosphoprotein 1(SPP1)in early diagnosis of esophageal cancer.Methods 276 patients from June 2021 to May 2023 were selected as the study objects.92 cases of esophageal cancer diagnosed by operation and pathology were esophageal cancer group,another 89 patients diagnosed as benign esophageal lesions through tissue biopsy were selected as the benign lesion group,and 95 healthy individuals who underwent physical examinations were collected as the healthy control group,general information such as age and gender of subjects in three groups were collected and organized;using pathological results as the gold standard,the accuracy of EUS in diagnosing esophageal cancer was verified;the expression of serum SPINK1 and SPP1 was compared among the esophageal cancer group,benign lesion group,and healthy control group;the relationship between the expression of serum SPINK1 and SPP1 in esophageal cancer patients and their clinical and pathological characteristics was explored;efficacy of EUS combined with serum SPINK1,SPP1 levels for early diagnosis of esophageal cancer was analyzed using receiver operator characteristic curve(ROC curve).Results Compared with the gold standard,the results of EUS examination showed that 81 cases were diagnosed with esophageal cancer,79 cases were diagnosed with benign lesions,11 cases were missed diagnosed,and 10 cases were misdiagnosed,with an accuracy rate of 88.40%(160/181);Compared with the healthy control group and the benign lesion group,the expression levels of serum SPINK1 and SPP1 in the esophageal cancer group were obviously increased,the expression levels of serum SPINK1 and SPP1 in the benign lesion group were significantly higher than those in the healthy control group,the differences were statistically significant(P<0.05);Serum SPINK1 expression was linked to tumor diameter>2 cm,presence of lymph node metastasis,lymph node positivity,and tissue grading level 3 in patients(P<0.05).Serum SPP1 expression level was related to tumor diameter>2 cm,presence of lymph node metastasis,lymph node positivity,and estrogen receptor positivity of patients(P<0.05);ROC curve showed that the area under the curve(AUC)of EUS,serum SPINK1,SPP1 levels,and their combination in the early diagnosis of esophageal cancer was 0.862,0.834,0.782,and 0.926,respectively,the clinical efficacy of the combination of the three in the early diagnosis of esophageal cancer was superior to that of EUS,serum SPINK1,and SPP1 alone(Z=2.30,Z=3.70,Z=4.23,P=0.022,P=0.000,P=0.000).Conclusion The expression levels of serum SPINK1 and SPP1 in esophageal cancer patients are abnormally up-regulated.The combination of EUS and serum SPINK1 and SPP1 has high clinical value in early diagnosis of esophageal cancer.

Objective To investigate the correlation between muscle mass and gait parameters in patients with cerebral small vessel disease(CSVD),as well as the impact of reduced muscle mass on the occurrence of falls in CSVD patients.Methods This study was employed a cross-sectional design.Ninety-five inpatients with CSVD confirmed by the Department of Neurology of the Seventh Medical Center of Chinese People's Liberation Army General Hospital from January 1,2022 to June 1,2023 were included consecutively.The 95 patients with CSVD were divided into two groups,namely the reduced muscle mass group and the normal muscle mass group,based on the criteria of appendicular skeletal muscle mass(ASM)≤7.0 kg/m2 for males and ASM ≤5.7 kg/m2 for females as reduced muscle mass.Baseline data(sex,age,years of schooling,number of accompanying diseases[hypertension,hyperlipidemia,diabetes,angina pectoris,myocardial infarction,and migraines]),cognitive function assessment results(mini-mental status examination[MMSE],verbal fluency test[VFT],clock drawing test[CDT],and trail-making test part-B[TMT-B]),gait characteristics(basic gait parameters[gait speed,stride time,stride length,stride frequency]and reanalysis gait parameters[variation coefficient of gait speed,stride time,stride length,stride frequency,and time-phase coordination index,gait asymmetry index]),CSVD imaging findings(cerebral microbleeds,lacunar infarcts,and white matter hyperintensities),and history of falls.The differences in baseline data,cognitive function assessment results,and gait characteristics between the reduced muscle mass group and the normal muscle mass group were compared and analyzed.Linear regression was used to analyze the correlation between muscle mass and gait parameters.The 95 CSVD patients were divided into fall group and non-fall group,and the differences in baseline data,cognitive function assessment results,gait characteristics,CSVD imaging findings,and muscle mass between the two groups were compared.Binary Logistic regression analysis was used to evaluate the impact of reduced muscle mass on falls.Results(1)The majority of patients in the reduced muscle mass group were females(67.7％[21/31]).There was a statistically significant difference in the sex distribution between the reduced muscle mass group and the normal muscle mass group(x2=6.143,P=0.013).There were no statistically significant differences in the other baseline characteristics and cognitive function between the two groups(all P＞0.05).(2)Compared to the normal muscle mass group,patients in the reduced muscle mass group had slower gait speed([0.72±0.16]m/s vs.[0.94±0.15]m/s),longer stride time([1.22±0.12]s vs.[1.08±0.08]s),shorter stride length([0.84±0.19]m vs.[1.00±0.14]m),and lower step frequency([100±9]steps/min vs.[112±8]steps/min).The coefficients of variation for gait speed(11.579[8.163,15.870]％vs.7.304[5.873,9.959]％),stride time(3.876[2.778,5.769]％vs.2.480[1.874,3.001]％),stride length(7.800[5.400,10.700]％vs.5.600[4.100,7.950]％),step frequency(5.313[3.568,7.272]％vs.3.674[3.099,5.082]％),and time-phase coordination index(5.894[4.392,9.080]％vs.3.828[3.031,5.972]％)were all increased,and the differences were statistically significant(all P＜0.05).There was no statistically significant difference in gait asymmetry index between the two groups(P＞0.05).Further analysis with sex and lacunar infarction as potential confounding factors showed that there were statistically significant differences in baseline gait parameters between the normal muscle mass group and the reduced muscle mass group(all P＜0.01).In the reanalysis of gait parameters,only the differences in the coefficients of variation for gait speed and stride time were statistically significant(both P＜0.05).(3)When analyzing ASM as a continuous variable,age and CDT as potential confounders,and stratifying by sex,the results showed that in male patients,baseline gait parameters(gait speed,stride time,stride length,and step frequency with 95％CI ranging from 0.057 to 0.152,-0.105 to-0.023,0.013 to 0.097,and 1.686 to 8.854,respectively),as well as coefficients of variation for stride time(95％CI-0.016 to-0.003)and stride length(95％CI-0.026 to-0.006),were correlated with muscle mass reduction(all P＜0.05).In female patients,gait speed(95％CI0.034 to 0.166)and coefficient of variation for gait speed(95％CI-0.059 to-0.010),stride time(95％CI-0.110 to-0.011),coefficient of variation for stride time(95％CI-0.025 to-0.001),and stride length(95％CI 0.018 to 0.163)were correlated with muscle mass reduction(all P＜0.05).(4)Muscle mass reduction was an independent risk factor for falls(OR,5.044,95％CI 1.840 to 13.827,P=0.002).Conclusions The preliminary analysis of this study suggests that there is a certain correlation between muscle mass and gait parameters in patients with CSVD.Additionally,the study indicates that a decrease in muscle mass among CSVD patients may increase the risk of falls.Therefore,it is important to prioritize the management of muscle mass in CSVD patients.

low-grade glioma(LGG)is a slow-growing primary brain tumor originating from glial cells.The overall prognosis of LGG is good but incurable.The vast majority of LGG will have relapses,and some even progress to high-grade glioma(HGG).The treatment of LGG is still controversial.The current treatment includes surgical resection,radiation therapy(RT),chemical treatment(CT),targeting and immunotherapy,but its effectiveness and safety need further clinical exploration.This article describes the treatment of LGG,including surgery,radiotherapy,chemotherapy,targeting and immunotherapy,in order to develop an individualized treatment plan and provide theoretical strategies for maximizing the survival time of patients and improving the prognosis of patients.

Objective:To explore the understanding on health-related quality of life(HRQoL)among the Chinese populations and to develop a HRQoL conceptual framework that can be used to guide the development of Chinese HRQoL instruments.Methods:Respondents of Chinese general population and patients populations were recruited from 31 provinces in China.One-to-one semi-structured qualitative interviews were conducted to collect the views and perceptions on HRQoL.Based on the grounded theory,multi-level coding of qualitative interviews was carried out,and the framework method was used to sort out and summarize the coding to develop the HRQoL conceptual framework in China.Results:A total of 68 respondents were included in the study.The study extracted 1 558 open coding from the qualitative interview,which were analyzed and sorted into 180 axial coding and 31 selective coding(dimensions).The HRQoL conceptual framework for the Chinese population with 6 themes was finally summarized.Conclusions:The HRQoL conceptual framework based on the health concepts and preferences of the Chinese population contains 6 themes,refers to symptoms,physical function,emotion,cognition,activities and social function.In particular,the items of appetite,sleep and fatigue identifies may reflect Chinese cultural specific perceptions on important aspects of HRQoL.

Objective:To explore the automated synthesis of glucagon-like peptide-1 receptor agonist 18F-AlF-1, 4, 7-triazacyclononane-1, 4, 7-triacetic acid (NOTA)-maleimide (Mal)-cysteine (Cys) 39-exendin-4 ( 18F-exendin-4), and verify its diagnostic efficacy on insulinoma with PET/CT. Methods:Using NOTA-Mal-Cys 39-exendin-4 as the labeled precursor, 18F-exendin-4 was obtained by constructing Al 18F one-step reaction sequence and using All in one multifunctional chemical synthesizer for radiolabelling, purification and preparation. After the quality control, 18F-exendin-4 PET/CT imaging was performed on 1 patient (female, 55 years old) with clinical suspicion of insulinoma. Results:Radiolabelling of 18F-exendin-4 took about 40 min, with the non-decay corrected radiochemical yield of (18.03±2.67)% ( n=3), the molar activity>39.74 GBq/μmol, and the radioactivity concentration>390.00 MBq/ml. The injection was a colorless transparent liquid with pH value of 6.5, and the radiochemical purity>96%. Results of bacteria and endotoxins testing met the standards of Pharmacopoeia of the People′ s Republic of China (2020). PET/CT image analysis showed a nodular high uptake of 18F-exendin-4 in the pancreatic body. The pathological and immunohistochemical results were consistent with the characteristics of neuroendocrine neoplasm (G2). Conclusions:The automatic radiolabelling of 18F-exendin-4 is successfully realized by All in one multifunctional chemical synthesizer. 18F-exendin-4 has been proved to be of clinical value in diagnosis of insulinoma, and is suitable for promotion in medical institutions equipped with medical cyclotrons.

Objective:To assess the impact of the construction of smoke-free government on the smoking and cessation behaviors of staff members.Methods:This was a retrospective cohort study. The study used stratified random cluster sampling method to select 144 government institutions from 31 Provinces (Autonomous Regions and Municipalities) and the Xinjiang Production and Construction Corps. The survey was carried out between October and November, 2023 by filling out questionnaires online among the insiders of the institutions and all the smoking staff members. The main indicators included the number of smokers before and after the construction of smoke-free governments and the measures for the construction of smoke-free governments. 144 questionnaires from insiders were recovered, all of which were included in the analysis; 1 776 questionnaires from smokers were recovered, including 1 716 valid questionnaires. The SAS 9.4 was used to perform χ 2 test and log-binomial regression analysis. Results:The percentage of smoking staff members decreased from 8.81% before the construction to 6.70% after the construction, and the difference was statistically significant ( χ 2=63.23, P<0.001). Comprehensive smoking ban in indoor public places ( OR=2.301, 95% CI: 1.433-3.694), punishment mechanism for smoking staff members ( OR=1.219, 95% CI: 1.124-1.322), smoking cessation competitions ( OR=1.865, 95% CI: 1.234-2.818) and reimbursement for or provision of smoking cessation medications ( OR=2.210, 95% CI: 1.002-4.874) were facilitators to motivate the smoking staff members to quit (all P<0.01). Numbers of smoking leaders ( OR=0.858, 95% CI: 0.807-0.913) and smoking years of smoking staff members ( OR=0.932, 95% CI: 0.918-0.946) negatively influenced the smoking staff members to quit (both P<0.001). Conclusions:The construction of smoke-free governments can effectively promote the smoking cessation behaviors of smoking staff members. In addition, comprehensive smoke-free policies, punishment mechanism for smoking staff members and activities such as smoking cessation competitions, and reimbursement for or provision of smoking cessation medications are important.
