Objective:To explore the cost-effectiveness and cost-benefit of chronic obstructive pulmonary disease (COPD) screening and intervention based on family doctor contract services.Methods:From January 2023 to October 2023, using purposive sampling and a cross-sectional survey method, 1 040 individuals aged 60 to 75 years who underwent physical examinations at community health service centers in Shanghai Minhang district were selected as research subjects. The subjects were divided into a control group ( n=532) and a study group ( n=508). The control group received conventional community health education and participated in a COPD screening and intervention program provided by the examination center. The study group received COPD screening and intervention provided by contracted family doctors under a tightly integrated medical consortium. The screening content for both groups included initial and follow-up risk assessment questionnaires, pulmonary function tests, bronchodilator tests, and CT scans. A comparative analysis was conducted on the screening compliance rate, positive rate, and cost-effectiveness and cost-benefit between the two groups. Results:A total of 251 individuals at high risk for COPD and confirmed COPD patients were identified through initial and re-screening in both groups, accounting for 24.13% of the subjects, including 222 individuals at high risk (21.35%) and 29 confirmed patients (2.79%). The study group had significantly higher compliance rates in questionnaire-based initial screening, questionnaire-based re-screening+pulmonary function tests, bronchodilator experiments, diagnosis, and subsequent CT scans than the control group ( χ2=33.563, 41.425, 24.842, 17.363, all P<0.05).There were significant higher proportions of high-risk individuals and patients identified through screening in the study group than those in the control group ( χ2=44.880, all P<0.05). The study group had significantly higher positive rates of questionnaire-based initial screening, pulmonary function tests, bronchodilator experiments, and CT scans than the control group ( χ2=29.191, 11.313, 12.370, 4.429, all P<0.05). The overall costs of the screening in the control and study groups were 36 100 and 53 900 yuan, respectively. The cost of pulmonary function tests in the screening for the control and study groups was 1.44 million and 2.45 million yuan, respectively, accounting for 43.19% of the total cost, which was the highest proportion among all costs. The per capita cost for identifying one high-risk individual or patient with COPD was 358.46 Yuan, and the cost in study groups was significantly lower than that in the control group (322.75 vs. 429.45 yuan, χ2=20.396, P<0.05). The per capita net benefits and cost-benefit ratios for the overall subjects in the two groups were 0.37 million yuan and 43.50, respectively. The average net benefit of the study group and the control group was 0.49 million yuan and 0.26 million yuan respectively. The average net benefit of the study group was 0.23 million yuan higher than that of the control group. The cost-benefit ratio of the study group and the control group were 46.77 and 38.61, respectively. The cost-benefit ratio of the study group was 8.16 higher than that of the control group. Conclusion:The screening and intervention for COPD based on family doctor contract services have significant effectiveness, with a marked improvement in screening compliance and high cost-effectiveness, and can be used in community medical institutions with relatively sound family doctor and medical consortium services for targeted COPD screening.

Objective:To explore the quality improvement in the organization structure and management model of the integrated community child health services.Methods:This was a qualitative study, including two parts: cause analysis and service improvement suggestions. In the analysis part the data mining was conducted to identify valuable patterns and relationships in the comprehensive child health services. Semi-structured interviews were conducted with 12 relevant department heads and health workers of the comprehensive child health service team at Gumei Community Health Service Center in December 2023, and the causes of the key problems were explored.

Objective:To investigate the prevalence of hyperuricemia (HUA), patients′ awareness of HUA, and related factors among elderly in community.Methods:The health check-up data of 6 897 residents aged over 65 years in Gumei Community of Shanghai were collected from January 2019 to January 2020. There were 1 156 subject with increased serum uric acid levels (HUA group) and 5 741 with normal uric acid levels (non-HUA group). The differences of clinical indicators between HUA group and non-HUA group were analyzed and the risk factors of HUA was determined by multivariate logistic stepwise regression. A questionnaire survey on the knowledge of HUA and the adoption of relevant health behaviors was conducted among HUA patients.Results:The overall prevalence was 16.8% (1 156/6 897) in this population. The prevalence in males was significantly higher than that in females[26.4%(842/3 195) vs. 8.5%(314/3 702), P<0.001); and the prevalence in females increased with age (χ 2=7.56, P=0.023). Body mass index(BMI), waist circumference(WC), total cholesterol(TC), triglyceride(TG), serum creatinine, alanine aminotransferase(ALT) and albumin/urine creatinine ratio(UACR) in the HUA group were significantly higher than those in the non-HUA group, while estimated glomerular filtration rate(eGFR) and high-density lipoprotein(HDL) were lower than those in the non-HUA group (all P<0.01). The prevalence of hypertension, decreased renal function, overweight or obesity, abdominal obesity, fatty liver and renal cyst in HUA group was significantly higher than that in non-HUA group (all P<0.01). High values of TG, low-density lipoprotein(LDL), WC, hypertension and fatty liver were risk factors for HUA( OR=1.14, 1.20, 1.03, 1.43, 2.19; P<0.01); while female gender, eGFR, HDL and glycosylated hemoglobin A1c(HbA1c) were protective factors for HUA( OR=0.32, 0.94, 0.65, 0.78; P<0.01). The questionnaire survey was conducted among 1 090 HUA patients, and the results showed that 73.2% (798 cases) were aware of the disease after the health check-up results released; only 30.9% (337 cases) knew the diagnostic criteria of HUA, 21.1% (230 cases) knew that HUA needed life-long follow-up care, 56.3% (614 cases), 49.2% (536 cases) and 47.9% (522 cases) thought that HUA should eat less seafood, broth and soya bean products, 17.0%(185 cases) were atcohol drinker and the awareness rates of above questions in patients with gout were higher than those in patients without gout ( P<0.05). Conclusion:The study shows that the prevalence of HUA among the elderly in Gumei community of Shanghai is high, and the HUA related knowledge levels and health behavior performance are not ideal, especially for HUA patients without gout, therefore health education should be strengthened for elderly residents in the community.

【Objective】 To prepare and preliminarily identify the specific monoclonal antibody (McAb) against-AB blood group antigen. 【Methods】 The human AB red blood cells were used to immunize BALB/c mice for producing monoclonal antibodies against human red cell AB antigens. The cell lines that can secrete AB monoclonal antibodies were obtained by cell fusion and screening using hybridoma cell technology.The specificity and recognized epitopes of anti-AB McAb were preliminarily identified by blood group serological assay. The antibody was also used to detect the clinical samples. 【Results】 One hybridoma cell line secreting IgM monoclonal antibody against human AB antigens was obtained. This anti-AB McAb could agglutinate with human red blood cells of type A, B and AB, but not agglutinate with type O red blood cells. The red blood cell absorption and elution test confirmed that the antibody recognized the common epitope of A and B. The anti-AB McAb obtained and the commercial anti-A and anti-B reagents were used to detect 567 clinical samples in parallel, with the concordance rate at 100%. 【Conclusion】 A hybridoma cell line secreting anti-AB McAb can be successfully prepared.

Objective:To explore the association of urinary phenol concentration and blood biochemical indices in coke oven workers.Methods:From April to may 2019, we investigated 771 employing coke oven workers from a coke plant in Taiyuan city, and categorized into benzene-exposed group ( n=402) and control group ( n=369) based on their benzene exposures in workplace and urophenol concentrations. All subjects were interviewed face-to-face using a questionnaire including name, age (year) , gender, smoking and drinking habits, personal vocational history, working length (year) , and occupational protection, etc. Post-shift urine samples detected using a gas chromatography-hydrogen flame ionization detector. Fasting venous blood was drawn in the morning and centrifuged, the separated serum were detected the following items using an automatic blood biochemistry analyzer. Covariance and multiple linear regression were used to test the association of urinary phenol concentration and the levels of all the blood biochemical indices. Results:The subjects were predominantly males ( n=719, 93.3%) , with an average age of (42.3±8.2) years and an average working length of (20.6±8.2) years. Compared with the control group, the benzene-exposed group were significantly different in age, working length of years, gender, smoking and drinking habits ( P<0.05) . The median (interquartile interval) concentration of urinary phenol was 6.00 (0.00-33.00) μg/ml in the benzene-exposed group, which was significantly higher than that in the control group ( P<0.05) . Covariance analysis indicated that the fasting blood glucose, total cholesterol and high density cholesterol in the benzene-exposed group were significantly reduced compared with the control group, yet the serum creatinine, serum uric acid and triglyceride were significantly increased ( P<0.05) . Multiple linear regression showed that, an increase of each natural logarithm (Ln) transformed urinary phenol concentration was significantly associated with increases in serum uric acid level [9.82 (95% CI: 2.18-17.47) μmol/L] and cholesterol level[0.10 (95% CI:0.00-0.20) mmol/L]. An increase of each Ln-transformed accumulated benzene exposure levels was significantly associated with an increase in total cholesterol level[0.09 (95% CI: 0.01-0.17) mmol/L]. Conclusion:Occupational benzene exposure is possibly related to the variation of purine and total cholesterol metabolism in coke oven workers.
