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.

ObjectiveTo analyze the characteristics and influencing factors of elderly hospitalized patients with carbapenem-resistant gram-negative bacillus (CRO) infection in the intensive care unit (ICU) of a gradeⅡ level A general hospital in Yangpu District of Shanghai, and to provide scientific basis for the prevention and control of hospital-acquired CRO infection in such hospitals. MethodsThe clinical data of elderly ICU patients (age ≥60 years) from January 2019 to December 2023 were retrospectively collected. A total of 122 cases with hospital-acquired CRO infection were used as the case group, and a total of 68 cases with carbapenem-sensitive gram-negative (CSO) infection were used as the control group. The clinical characteristics of the two groups were analyzed, and univariate analysis and logistic regression analysis were performed for screening for possible influencing factors on hospital-acquired CRO infection. ResultsThe main pathogens of CRO infection were carbapenem-resistant Acinetobacter baumannii (CRAB) (53 cases, 43.44%) and carbapenem-resistant Klebsiella pneumoniae (CRKP) (46 cases, 37.70%), and 17 patients (13.93%) had more than two types of CRO infection. Among the CRO infection, the main sites were lower respiratory tract infection (58 cases, 47.54%), ventilator-associated pneumonia (21 cases, 17.21%), and catheter-associated urinary tract infections (16 cases, 13.11%). The incidence rate of poor prognosis was higher in the CRO infection group (54.10%) than that in the CSO infection group (36.76%) (P=0.021). The results of univariate analysis showed that male, history of hospitalization within three months, chronic respiratory disease, hypoproteinemia, anemia, and history of invasive procedures prior to infection, including indwelling central venous catheter, invasive mechanical ventilation, urinary catheter, gastric tube placement and parenteral nutrition, in addition, heparin anticoagulation, the use of broad-spectrum penicillin, third-generation cephalosporins, fluoroquinolones, carbapenems, carbapenems combined with fluoroquinolones, carbapenems combined with glycopeptides, use of ≥3 antibiotics and long time of antibiotic use prior to infection were all associated with the CRO infection (P<0.05). The results of logistic regression analysis showed that use of carbapenems (OR=7.739, 95%CI: 2.226‒26.911), ≥3 types of antibiotics (OR=6.307, 95%CI: 1.674‒23.754), invasive mechanical ventilation (OR=4.082, 95%CI: 1.795‒9.281), urinary catheter (OR=3.554, 95%CI: 1.074‒11.758), and comorbid hypoproteinemia (OR=4.741, 95%CI: 2.039‒11.022) and diabetes (OR=3.245, 95%CI: 1.344‒7.839) were positively correlated with the risk of CRO infection. ConclusionConcurrent use of carbapenems with multiple other antibiotics, as well as the use of invasive mechanical ventilation, urinary catheter, and comorbid hypoproteinemia and diabetes, may be associated with an increased influencing of CRO infection. More attention should be paid to the prevention and control of infection in elderly patients with the above-mentioned risk factors, and active screening of drug-resistant bacteria should be strengthened. Besides, the rational use of broad-spectrum antibiotics such as carbapenems, avoiding unnecessary invasive operations, and paying attention to patient nutrition and blood glucose control all can reduce the incidence of CRO infection and help to improve clinical outcomes.

Operation management is an important tool to promote the high-quality development of public hospitals in China.Since the founding of New China,based on China's economic and social development and medical and health system reform,the evolution of operation management of public hospitals in China can be divided into four stages,the system building stage(1949-1978),the liberalization and revitalization stage(1979-1996),the operation mechanism reform stage(1997-2020),and the new stage of high-quality development(2021 present).The development trend of public hospital operation management in future should deepen the public welfare-oriented public hospital operation management,explore the value-oriented medical operation management model based on high-quality development and the refined operation and management model of public hospitals,so as to promote the high-quality development of public hospitals in China.

OBJECTIVE To investigate the current status of bloodborne occupational exposures among healthcare workers in a three-A specialized hospital of Shanghai so as to provide bases for formulating prevention measures for occupational exposures.METHODS A questionnaires titled'Survey of bloodborne occupational exposures among healthcare workers'were clinically distributed to Eye &ENT Hospital of Fudan University through'Wenjuanxing platform'from Feb.2024 to Apr.2024.The content of the questionnaire included four parts:the baseline data questionnaire,incidence of occupational exposures,awareness of knowledge about occupational exposures,and preventive behaviors regarding occupational exposures.RESULTS A total of 995 valid questionnaires were collect-ed in the survey,the result of the survey showed that the incidence of bloodborne occupational exposures was 10.65％.The clinicians and doctors engaging in advanced studies were at high risk of the occupational exposures especially when they were busy with work.The result of the survey indicated that the rate of missing report was 71.33％,the implementation rate of monitoring was only 48.11％after the exposures,of which the major cau-ses included the health care workers'insufficient attention to the exposure events,flaws in prevention and control of occupational exposures and some personnels'poor awareness of reporting process and requirements for monito-ring.Although the awareness rate of emergency processing exceeded 90％,the awareness rate of the knowledge a-bout prophylactic use of antibiotics and prevention of needlestick injuries,and the preparations before diagnosis and treatment,standardized operations and use of protective articles still needed to be improved.CONCLUSIONS The survey reveals that the health care workers pay less attention to the risk of infections,and the prevention of occupational exposure needs to be improved.It is of great importance to raise the awareness of prevention and en-hance the systematic training for occupational exposure.

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.

To explore the correlation between the level of serum interleukin-6 (IL-6) and the severity of infection in patients with diabetic foot (DF) and the auxiliary value of IL-6 in DF diagnosis, and aim to provide reference for clinical treatment. Based on the hospital medical record system and the laboratory system, a retrospective analysis with case-control study was conducted on the data of patients in Liyuan Hospital affiliated to Tongji Medical College, Huazhong University of Science and Technology from January 2020 to September 2024. A total of 377 patients′ information was collected, including 31 cases in control group with 17 males and 14 females from 31 to 91 years old and a median age of 71, 63 cases in NDF group with 43 males and 20 females from 37 to 96 years old, with a median age of 71, and 283 patients in DF group with 197 males and 86 females from 36 to 96 years, with a median age of 67. According to classification of infection severity, paints in the group of diabetes with DF were divided into mild infection subgroup (72 cases), moderate infection subgroup (143 cases) and severe infection subgroup (68 cases). The results showed that there were no statistically significant differences in age and gender among the three groups in the study ( F=1.795/ χ 2=2.81, P>0.05). The non parametric test results showed that there were statistically significant differences in IL-6, C-reactive protein (CRP), procalcitonin (PCT), white blood cell (WBC) and glucose (GLU) among the three groups of patients ( H=12.480, 36.277, 12.432, 12.838, 18.334, P<0.05). The pairwise comparison results showed that compared with the control group, the NDF group had higher levels of CRP, PCT and GLU ( H=20.259, 20.118, 20.056, P<0.05), and the levels of IL-6, CRP, PCT and WBC( H=14.934,14.933,14.829,14.934, P<0.05) were higher in the DF group. Both of the differences were statistically significant. But the difference of IL-6, CRP, PCT, WBC and GLU between the NDF and DF group was not statistically significant( H=1.202,0.622,0.737,1.036,1.899, P>0.05). In DF group, there were statistically significant differences in IL-6, CRP, PCT, WBC, and GLU levels among patients in the three infection subgroups ( H=11.174, 15.136, 8.657, 8.348, 3.698, P<0.05).Compared to the mild subgroup, the levels of IL-6, CRP, PCT, WBC and GLU were higher in the severe subgroup were higher( H=111.789,237.066,74.683,83.203,15.328, P<0.05) and the levels of IL-6, CRP, PCT in the moderate subgroup were higher ( H=6.877, 8.846, 5.183, P<0.05). And both of the differences were statistically significant. But there was no statistically significant difference in WBC and GLU level between the mild and the moderate subgroup( H=1.684, 1.039, P>0.05). The severity of infection in diabetic foot patients was positively correlated with the IL-6 level ( OR=1.033, 95% CI: 0.024-0.043, P<0.05). ROC curve showed that AUC of IL-6 for diagnosis in diabetic foots were 0.635. And joint testing showed that the AUC of IL-6+CRP, IL-6+PCT and IL-6+WBC were 0.718, 0.621, and 0.638 respectively. In conclusion,the level of serum IL-6 may be positively correlated with the severity of infection in diabetic foot patients, which may have auxiliary diagnostic value in predicting diabetic foot infection. And it may provide a reference for the grading of infection severity in diabetic foot patients to gauging serum IL-6 level.
