ObjectiveTo explore the 28-day mortality risk of Klebsiella pneumoniae (KP) bloodstream infections (BSI) and its related influencing factors, thereby providing a scientific basis for the effective control of KP-BSI and improvement of patient prognosis. MethodsFrom January 2018 to December 2024, a retrospective review was conducted on hospitalized patients aged >18 years old treated for KP-BSI at a tertiary hospital in Hangzhou. Logistic and Cox regression analyses were performed to identify the epidemiological characteristics and the risk factors for the 28-day mortality associated with KP-BSI. ResultsA total of 123 patients with KP-BSI were included in this study, comprising 64 cases infected with carbapenem-resistant Klebsiella pneumoniae (CRKP) and 59 cases infected with carbapenem-susceptible Klebsiella pneumoniae (CSKP). Compared with CSKP-BSI, patients with CRKP-BSI more frequently presented with chronic pulmonary disease (χ²=4.29, P=0.038), concomitant infections at other sites (χ²=10.90, P=0.001), and a higher frequency of invasive procedures prior to infection (central venous catheterization, mechanical ventilation, and indwelling urinary catheter), as well as glucocorticoid use, hemodialysis, and blood transfusion (all P<0.05). The 28-day mortality was significantly higher in BSI cases caused by CRKP compared to that caused by CSKP (37.50% vs 5.08%, P<0.001). Cox regression analyses revealed that carbapenem resistance (HR=6.67, 95%CI: 1.48‒30.08, P=0.014) and blood transfusion (HR=3.58, 95%CI: 1.15‒11.19, P=0.028) were risk factors for the 28-day mortality in KP-BSI, while removal of central venous catheters after infection (HR=0.24, 95%CI: 0.08‒0.67, P=0.006) was associated with a reduced risk for the 28-day mortality. ConclusionCarbapenem resistance is associated with mortality outcomes in patients with KP-BSI. Strengthening infection control measures targeting the identified risk factors for CRKP-BSI may improve patient prognosis.

ObjectiveTo investigate the current professional competency among full-time and part-time personnel of the nosocomial infection control administration in Shanghai, so as to provide a scientific basis for future training programmes. MethodsIn December 2024, a questionnaire survey was conducted by the Shanghai Nosocomial Infection Quality Control Center among full-time and part-time personnel of the nosocomial infection control administration across medical institutions at various levels and types in Shanghai using convenience sampling method. The questionnaire consisted of two parts: demographic information and professional competency assessment. The professional competency scale comprised four dimensions: fundamental cognition, basic skills, professional expertise, and personal qualities, totaling 35 items. ResultsA total of 1 179 questionnaires were distributed, with 1 144 valid responses collected, yielding an effective response rate of 97.03%. Statistically significant differences were observed among full-time and part-time personnel of the nosocomial infection control administration in terms of age (t=5.32, P=0.021), professional background (χ²=9.90, P=0.019), educational qualifications (χ²=19.10, P<0.001), professional titles (χ²=12.60, P=0.002), and the levels of medical institutions (χ²=111.08, P<0.001). The scores of full-time personnel of the nosocomial infection control administration in fundamental cognition [92 (82, 99) points] and basic skills [88 (78, 96) points] were significantly higher than those of part-time personnel(Z=-2.21, P=0.027;Z=-2.74, P=0.006). Statistically significant differences were found in fundamental cognition scores between full-time and part-time personnel of the nosocomial infection control administration regarding occupational safety protection, definition of healthcare-associated infection outbreaks, types of drug-resistant bacteria and their prevention and control strategies, and transmission routes of different infectious diseases (all P<0.05). Statistically significant differences were also observed in basic skills scores including proficient use of monitoring platforms, formulation and revision of standard operating procedures (SOPs), independent completion of targeted surveillance, guidance on basic infection control skills, guidance for key departments, and follow-up of personnel with occupational exposure (all P<0.05). However, no statistically significant differences were found in scores of professional knowledge and personal qualities (P>0.05). ConclusionThere are certain differences in professional competency between full-time and part-time personnel of the nosocomial infection control administration in Shanghai in terms of fundamental cognition and basic skills. Part-time personnel can effectively improve their professional competency through systematic training on basic infection control knowledge and practical skills, thereby comprehensively enhancing the overall quality of the nosocomial infection administration team.

ObjectiveTo construct an evaluation index system for public health emergency response capacity within the healthcare-associated infection prevention and control systems using the Delphi method, and to provide a basis for infection control management in municipal hospitals. MethodsBased on literature analyses and theoretical researches, a preliminary evaluation index system for response capacity was constructed. The Delphi method was employed to conduct two rounds of consultation with 17 experts. The Analytic Hierarchy Process (AHP) was used to calculate the weights of the indicators. ResultsThe effective questionnaire return rates for both rounds of expert consultation were 100%. The expert authority coefficients for the first and second rounds were 0.97 and 0.95, respectively. Kendall’s W coefficients ranged from 0.31 to 0.58 in the first round and from 0.45 to 0.58 in the second round, with all differences being statistically significant (P<0.01). After two rounds of expert consultation, the municipal-level hospital infection prevention and control system emergency response capacity evaluation index system was finalized, comprising 5 first-level indicators, 18 second-level indicators and 59 third-level indicators. ConclusionThe constructed public health emergency response capacity evaluation index system for municipal-level hospital infection prevention and control systems demonstrates strong scientific rigor, reliability, and practicality, providing a theoretical foundation and valuable reference for enhancing the infection prevention and control capacity of municipal-level hospitals.

OBJECTIVE To screen and quantitatively analyze the quality marker （Q-Marker） associated with anti-renal fibrosis in Shenqi shenshuai mixture （SQSS）， so as to provide references for the analysis of pharmacodynamic substances and new drug transformation of SQSS. METHODS The chemical components of SQSS were characterized by untargeted metabolomics. Combined with network pharmacology， gene expression omnibus （GEO） and connectivity map （CMAP） databases， the anti-renal fibrosis Q-Markers of SQSS were screened. HPLC-MS/MS was applied to determine the contents of Q-Markers in 10 batches of SQSS. RESULTS A total of 1 319 compounds were identified from SQSS via untargeted metabolomics，and 84 active ingredients with anti-renal fibrosis activity were further screened out， such as formononetin. Nine anti-renal fibrosis Q-Markers were obtained by network pharmacology and GEO database， including berberine， quercetin， honokiol， nicotinamide， daidzein， coumarin， kaempferol， formononetin and amygdalin. The quantitative results showed that the average contents of the above components （excluding amygdalin） in 10 batches of SQSS were 2.523， 1.942， 26.848， 1.415， 0.692， 0.171， 0.374， 7.401 μg/mL， respectively. CONCLUSIONS Nine anti-renal fibrosis Q-Markers of SQSS were screened in this study， and the contents of eight among them were determined. The results can provide a basis for elucidating the pharmacodynamic material basis and promoting the new drug transformation of SQSS.

BACKGROUND: Death burden of stroke is severe with over one-third rural residents in China, but there is still a lack of specific national and high-quality reports on the urban-rural differences in stroke burden, especially for subtypes. We aimed to update the understanding of urban-rural differences in stroke deaths. METHODS: This is a descriptive observational study. Data from the national mortality surveillance system, which covers 323.8 million with 605 disease surveillance points (DSPs) across all 31 provinces, municipalities, and autonomous regions in China. All deaths from stroke as the underlying cause from 2015 to 2020 according to DSPs. Crude mortality rate and age-standardized mortality rate (ASMR) were estimated through DSPs. Average annual percentage change was used to explain the change in mortality rate. RESULTS: From 2015 to 2020, the majority of deaths from all stroke subtypes occurred in rural areas. There were significant differences between the changes of urban and rural ASMRs. On the whole, the changes in urban areas were evidently better, and the ASMR differences were basically expanding. Stroke ASMR in urban China decreased by 15.5%. The rural ASMR of ischemic stroke increased by 12.9%. The rural and urban ASMRs of intracerebral hemorrhage decreased by 24.9% and 27.4%, and those of subarachnoid hemorrhage decreased by 29.5% and 40.4%, respectively. The highest ASMRs of all stroke subtypes and the increasing trend of ischemic stroke ASMR make rural males the focus of stroke management. CONCLUSIONS The death burden of stroke varies greatly between urban and rural China. Rural residents face unique challenges.

Objective:To analyze the clinical and endoscopic features of elderly patients with early gastric neuroendocrine neoplasms(g-NEN)to provide insights for clinical diagnosis and treatment.Methods:Seven cases of early-stage g-NEN in elderly patients admitted to Beijing Hospital from May 2020 to October 2024 were reported.Information including patient demographics, medical history, laboratory findings, endoscopic features, and pathological results was summarized an analyzed.Meanwhile, a literature review was conducted on g-NEN cases reported domestically and internationally from the establishment of databases to April 2025, with a comparative analysis of baseline characteristics, background mucosal conditions, and pathological diagnoses.Results:A total of 7 elderly patients with early g-NEN were included, including 3 males and 4 females, with an average age of 67 years at diagnosis.Endoscopic and pathological features: endoscopic lesions were mainly located on the greater curvature of the stomach, mostly slightly elevated, with 4/7(57.1%)being single lesions and the others accompanied by multiple polyps.The size of gastric neuroendocrine tumor(g-NET) lesions ranged from 1 mm to 19 mm, with a median Kyoto gastritis score of 3.In terms of pathological grading, there were 6 cases of G1 and 1 case of gastric neuroendocrine carcinoma(g-NEC). All 7 patients underwent endoscopic submucosal dissection(ESD). The follow-up period after surgery ranged from 3 months to 4 years, and no tumor was found at the vertical and horizontal margins of all lesions on pathology.A literature review of 32 reported cases showed that 40.6%(13/32)of cases exhibited background mucosal atrophy or intestinal metaplasia, with positive rates of chromogranin A(CgA) and synapsin(Syn)reaching 95.8%(23/24) and 100.0%(25/25), respectively.Notably, elderly patients with g-NEC demonstrated aggressive invasiveness, with a metastasis rate of 62.5%(5/8).Conclusions:Elderly patients with g-NEN exhibit high heterogeneity and significant differences in invasiveness, necessitating heightened clinical vigilance.Precise management should integrate background mucosal status, Kyoto gastritis score, pathological biomarkers, and imaging techniques.Blue laser imaging with magnifying endoscopy(BLI-ME)and endoscopic ultrasonography(EUS)can further analyze the characteristics of these tumors, and endoscopic submucosal dissection(ESD)remains the primary treatment modality for early-stage g-NEN.

Objective:To actively screen the dynamic colonization of Enterobacteriaceae in the gastrointestinal tract of tumor patients and explore the homology between carbapenem-resistant Enterobacteriaceae(CRE)colonized in the gastrointestinal tracts of these patients and the bacteria causing bloodstream infections,to provide meaningful reference data for diagnosis and treatment by clinicians.Methods:A total of 32 strains of gram-negative bacilli were isolated from 353 intestinal specimens of tumor patients at The First Affiliated Hospital of Henan University of Science and Technology from December 2021 to November 2022.The bacterial identification instruments VITEK 2 Com-pact,a carbapenemase detection kit using colloidal gold immunochromatography,and polymerase chain reaction(PCR)were used to de-tectdrug resistance genes and phenotypes.Pulsed-field gel electrophoresis(PFGE)was used to analyze and compare the homology between CRE strains in the intestinal tract of patients and pathogenic microorganisms causing bloodstream infections.Results:Among the 32 strains of Gram-negative bacilli screened from the gastrointestinal tract of cancer patients,6 strains(1.6%,6/353)were carbapenem-resistant Kleb-siella pneumoniae(CRKp).All six CRKp strains harbored blaKPC gene.The proportion of CRE is 3.3%(12/353).Bloodstream infection oc-curred in 2 patients with intestinal colonization of Klebsiella pneumoniae,which was caused by the same CRKp strain as intestinal coloniza-tion.Conclusions:The proportion of CRE intestinal colonization in tumor patients was not high;however,under certain circumstances,CRE colonized in the intestines of tumor patients can cause ectopic infections else where in the body,including the bloodstream,which should be closely monitored.The findings indicate the importance of increased attention to critically ill patients who have undergone multiple hospital-izations with long hospitalization times,as well as early screening for intestine-colonizing microorganisms and rational regulation of the anti-biotic usage.
