This report evaluates the preliminary outcomes of a "six-in-one" integrated cough and asthma center developed under a dual-contract physician model at the Changfeng Community Health Service Center in Putuo District, Shanghai. By combining the efforts of family doctors and medical specialists, the center integrated six core functions-clinical treatment, prevention, nursing, rehabilitation, pharmacy, and nutrition-into a seamless management system covering screening, diagnosis, therapy, and follow-up. Supported by specialist guidance and teaching clinics, the model significantly enhanced comprehensive respiratory disease management capabilities within the community setting. The initiative not only improved patient health outcomes but also strengthened multidisciplinary collaboration and resource efficiency, offering a replicable example for improving chronic disease management in primary care through integrated and coordinated service delivery.

Since 2017, Changfeng Community Health Service Center in Putuo District, Shanghai, has innovatively integrated the "Dual-Contracting" program by combining integrated general-specialist outpatient services with teaching clinics. This integration has progressively evolved into a comprehensive general practitioner (GP) training model. This model cultivates competencies encompassing: core service delivery, specialized disease diagnosis and treatment, complex case management, chronic disease management within specialties, teaching and mentoring skills, and capacities for self-reflection and continuous learning. It effectively bridges the training objectives and needs for GPs across both pre-service and in-service stages. Against the backdrop of senior medical experts being deployed to primary care settings, this model not only systematically enhances the professional competencies of community GPs but also optimizes medical resource utilization and elevates the overall quality of healthcare services.

Objective To investigate the current situation of personnel training,material alloca-tion,process implementation and quality monitoring of gastrointestinal endoscopy cleaning and disin-fection in medical institutions at all levels in Yangzhou City,so as to provide reliable data for further improving the quality management of digestive endoscopy cleaning and disinfection in the city.Meth-ods According to the latest industry standards,a questionnaire was designed to carry out an online questionnaire survey on the status quo of digestive endoscopy cleaning and disinfection in 74 medical institutions of different levels in Yangzhou City,and the results were analyzed.Results 50％of the city's hospitals adopt the way of self-training within the department,and only 22 people have obtained the provincial or above professional cleaning and disinfection certificate.In 21.62％of hospitals,cleaning and disinfection personnel were not assessed before starting work.13.51％of the hospitals did not use purified water for terminal rinsing,and 44.59％of the hospitals did not have a cleaning and disinfection machine.79.73％of hospitals recorded by hand.71.62％of the hospitals failed to carry out standard cleaning quality monitoring,83.78％of the hospitals did not implement biofiltra-tion monitoring method.In addition,in the biological monitoring in 2023,14.86％of hospitals had the problem of excessive microorganisms.Conclusion The implementation of endoscope cleaning and disinfection standards varied significantly among medical institutions in Yangzhou,with level one and level two hospitals posing potential hospital infection risks.It is recommended to establish a pro-fessional entry system for endoscope cleaning and disinfection personnel citywide,increase investment in hardware facilities,and strictly enforce monitoring standards.

Objective:To investigate the role of inhibitor of differentiation 2(Id2)in inducing the generation of central memory T(Tcm)cells and enhancing the anti-tumor persistence of T cells.Methods:CD8+na?ve T cells were sorted with magnetic beads and then co-cultured with carcinoembryonic antigen(CEA)-loaded dendritic cells(DCs).These cells were induced into effector T(Teff)or Tcm cells by interleukin-2(IL-2)or IL-7/15/21/23,respectively.The mRNA and protein expression of Id2 and Id3 in T cells were detected using qPCR and WB,respectively.Id2 gene in T cells was knocked down using lentivirus,and the T cell memory phenotype was analyzed by flow cytometry.The expression of PI3K/AKT pathway-related proteins was examined by WB.The extracellular acidification rate(ECAR)and oxygen consumption rate(OCR)were assessed using a Seahorse extracellular flux analyzer.A zebrafish colorectal cancer HCT116 xenograft model was employed to analyze the anti-tumor differences between Teff and Tcm cells.The effect of Id2 gene knockdown in Tcm cells(Tcm-shId2)on the growth inhibition of secondary xenografts was also observed.Results:Tcm cells exhibited high expression of Id3 mRNA(P<0.05),whereas Teff cells showed high expression of Id2 mRNA(P<0.001).Tcm cells with Id2 knockdown(Tcm-shId2)were successfully constructed,showing significantly upregulated Id3 expression.Knockdown of Id2 promoted the formation of Tcm cell(P<0.05).Tcm-shId2 cells underwent metabolic reprogramming via the PI3K/AKT pathway,which effectively suppressed the growth of colorectal cancer xenografts in zebrafish and also produced significant inhibitory effects on secondary tumor growth(P<0.01).Conclusion:Id2 gene may regulate T cell metabolism through the PI3K/AKT signaling pathway,promoting the differentiation of CD8+T cells into Tcm cells and effectively inhibiting the growth of colorectal cancer xenografts.

Objective To investigate the influencing factors of low cardiac output syndrome(LCOS)after coronary artery bypass grafting(CABG)and construct a nomogram model to predict the risk of LCOS occurrence.Methods A total of 231 patients with coronary atherosclerotic heart disease who underwent CABG surgery in the Heart Center of Henan Provincial People's Hospital from October 2019 to May 2022 were selected for the study.The patients were randomly divided into a training set(n=162)and a validation set(n=69)at a ratio of 7∶3.The comparability between the parameters of the patients in the training and validation sets was assessed.Based on the occurrence of LCOS after CABG,patients in the training set were divided into LCOS group(n=33)and non-LCOS group(n=129).Univariate and multivariate logistic regression analysis were conducted on the sample parameters in the training set to identify independent risk factors for LCOS after CABG.A nomogram prediction model for the risk of LCOS after CABG was constructed,and its discrimination,calibration,and clinical applicability were evaluated by using the receiver operating characteristic curve,calibration curve,and decision curve analysis.Results The incidence of LCOS in patients of the training and validation sets was 20.37％(33/162)and 18.84％(13/69),respectively.There were no statistically significant differences in various parameters between the training and validation sets(P＞0.05).In the training set,there were statistically significant differences in the following parameters between the non-LCOS group and the LCOS group patients,including age,heart rate,blood urea nitrogen,serum creatinine,estimated glomerular filtration rate(eGFR),serum N-terminal pro B-type natriuretic peptide(NT-proBNP),serum troponin T,left ventricular ejection fraction(LVEF),mitral regurgitation area,history of myocardial infarction,proportion of NYHA class Ⅲ-Ⅳ,proportion of patients requiring cardiopulmonary bypass,surgical duration,intraoperative bleeding volume,and postoperative hemodynamic indicators such as central venous pressure,pulmonary arterial diastolic pressure and pulmonary artery pulse index(PAPI)(P＜0.05).Multivariate logistic regression analysis showed that preoperative LVEF decrease[odds ratio(OR)=0.891,95％confidence interval(CI):0.832-0.954,P=0.001)],preoperative eGFR decrease(OR=0.963,95％CI:0.934-0.994,P=0.018),preoperative NT-proBNP increase(OR=1.001,95％CI:1.000-1.001,P=0.006),increased operation time(OR=1.013,95％CI:1.003-1.022,P=0.008),and postoperative PAPI reduction(OR=0.094,95％CI:0.028-0.319,P=0.000)were independent risk factors for LCOS after CABG.A nomogram prediction model was built based on these indicators.In the training set,the nomogram prediction model had an area under the curve(AUC)of 0.931(95％CI:0.890-0.972)for predicting the LCOS occurrence,with a sensitivity of 82.20％and a specificity of 90.90％.In the validation set,the AUC for predicting the LCOS occurrence was 0.907(95％CI:0.813-1.000),with a sensitivity of 96.40％and a specificity of 84.60％.This indicated that the model had high discrimination.The calibration curve showed good consistency between the predicted probability and the actual probability of LCOS occurrence in both the training and validation sets(average absolute error:0.038 and 0.026,respectively).The Hosmer-Lemeshow goodness-of-fit test demonstrated that the model's prediction deviation for the LCOS occurrence was not statistically significant compared to the actual occurrence(x2=6.381,6.907,P＞0.05),indicating good calibration of the model.Conclusion Decreased LVEF and eGFR and elevated NT-proBNP preoperatively,prolonged surgical duration,and decreased PAPI postoperatively are independent risk factors for LCOS after CABG.The nomogram prediction model established based on these factors has high discrimination,calibration,and clinical applicability,and can effectively predict the occurrence of LCOS after CABG.

From November 2020 to November 2021, the TEST(Task-Experience- Supervise-Thinking) teaching model was adopted for general practice residency training in teaching clinic of Changfeng Health Service Center of Shanghai Putuo district. The satisfaction of mentors, residents and patients was surveyed with self-assessment questionnaire. The satisfaction scores of mentors, residents and patients were (79.89±0.40), (79.96±0.19) and (49.92±0.40). The adaption of model TEST in teaching clinic is more effective in training of clinical competency, communication ability, management ability and narrative ability for general practice residents. It is also beneficial for mentors to upgrade their teaching ability, as well as for patients to improve their experience and satisfaction for seeking medical service. It is worth popularizing in the community practice base of general resident training.

Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.

Objective:To explore the effect of family doctor-specialist dual-contract service model on the management of type 2 diabetic patients in the community.Methods:Two hundred patients with type 2 diabetes mellitus (T2DM)who were treated in Changfeng Community Health Service Center between February 2019 and January 2021 were selected as the study objects by cluster sampling method. Patients were randomly divided into study group and control group with 100 cases in each group. The control group was managed with the conventional family doctor contract service, and the study group was managed with the family doctor-specialist double contract service. After one year of management, the fasting blood glucose, 2 h-postprandial blood glucose, glycosylated hemoglobin, diet control, blood glucose monitoring, medication compliance, exercise and other health behaviors, quality of life and satisfaction of patients were compared between two groups.Results:After intervention, fasting blood glucose, 2 h-postprandial blood glucose and glycosylated hemoglobin in the study group were significantly lower than those in the control group ( t=10.29, 8.49, 7.99, all P<0.05); the health related behaviors such as diet control, exercise behavior, blood glucose monitoring, and medication compliance in the study group were significantly better than those in the control group ( t=9.78, 6.72, 39.81, 7.88, all P<0.05); the quality of life in patients of study group was higher than that of the control group ( P<0.05); the satisfaction rate in study group was higher than that of control group (90.0% vs. 69.0%, χ 2=6.39, P=0.031). Conclusion:Compared with conventional family contract service model, the double contract service improves patient self-management, helps to reduce the blood glucose level and gains high patients′ satisfaction, which is worth promoting and applying in the management of type 2 diabetic patients in the community.
