RESUMO
Objective:To analyze the demands of contracted family doctor service among uncontracted young and middle-aged people in Shanghai Baoshan.Methods:An online questionnaire survey on demands of contracted family doctor service was conducted in June 2021 among 702 uncontracted residents aged 18-60 years from Shanghai Baoshan district selected by stratified random sampling method. The demands of contracted family doctor service, including digital health file, routine laboratory tests and imaging investigation;health promotion;service convenience; home service were surveyed, and the factors related the demands were analyzed with regression analysis.Results:The survey showed that the demands of service convenience (3.8(3.0, 5.0)) and home service (4.0(3.0, 5.0)) were higher, while those of digital health file (3.0(2.0, 5.0)) and health promotion (3.0(2.0, 5.0)) were relatively lower. There were significant differences in the demands of all five contracted services among residents with different gender, age, education level, household register and family income (all P<0.05); while for young residents with different types of medical insurance there was significant difference in demands of all contracted services except digital health file (all P<0.05). Logistic regression analysis indicated that female( OR=1.83, P<0.001), high educational level( OR=4.81, P=0.019), household registered in Shanghai( OR=1.80, P=0.004)had higher demand for service convenience; female gender( OR=1.68, P=0.001), high educational level( OR=4.56, P=0.023)had higher demand for home service demands. Conclusion:The demands for contracted family doctor services are different among the uncontracted young and middle-aged people in Baoshan district, while the service convenience is generally most demanded. The study indicates that the contracted family doctor service should be provided accordingly.
RESUMO
OBJECTIVE: To explore the spontaneous non-tumor lesion of kidney and its correlation with different age and sex in SD rats. METHODS: Eight hundred specific pathogen free SD rats were collected from the blank control groups used in subacute toxicity tests,subchronic toxicity tests and 1 or 2 years of chronic toxicity combined with carcinogenic tests. Rats were randomly divided into 4 groups with 10,19,56 or 108 weeks of experimental periods. Each group consisted of 100 female and 100 male rats. The renal tissues were collected at the end of each experiment,and the renal organ coefficients were calculated. The pathological non-tumor changes of the kidneys were analyzed. RESULTS: The renal organ coefficients in female rats at the age of 56 and 108 weeks were both lower than that of 10 and 19 weeks( P < 0. 008). The renal organ coefficient of male rats at the age of 56 weeks was lower than that of 10 and 19 weeks( P < 0. 008). The renal organ coefficient of male rats at the age of 108 weeks was higher than that of 56 weeks( P < 0. 008). The renal organ coefficient of male rats at the age of 108 weeks was higher than that of female rats of 108 weeks( P < 0. 008). The incidence of renal tubular calcium salt deposition,interstitial inflammatory cell infiltration and renal tubular dilatation in the female rats at the age of 108 weeks were higher than those in the male rats at the age of 108 weeks( P < 0. 05). The chronic progressive nephropathy incidence of female rats at the age of 108 weeks was lower than that of male rats aged 108 weeks( P < 0. 01).The renal tubular calcium salt deposition incidence of female rats aged 56 weeks was higher than that of male rats aged 56weeks( P < 0. 01). CONCLUSION: The spontaneous non-tumor lesions in the kidney of SD rats were common. The incidence of some lesions was different in the same age group with different sex.
RESUMO
OBJECTIVE: To explore the non-neoplastic hepatic lesions in SD rats at different ages. METHODS: The specificpathogen free SD rats were collected from the blank control groups used in subacute toxicity tests,subchronic toxicity tests and chronic toxicity combined with carcinogenic tests for safety evaluation. At the end of each experiment,i. e. week 10,19,56 and 108(assigned into four groups: 10,19,56 and 108 weeks,each contained 100 rats with each sex),rats were executed. The liver organ coefficient was calculated,the pathological examination was performed,and the non-tumorous lesions in the liver were analyzed. RESULTS: The liver organ coefficients at the age of 19,56,108 weeks were lower than that of 10 weeks(P < 0. 05); those at the age of 56 and 108 weeks were lower than that of 19 weeks(P < 0. 05),and that of 108 weeks was greater than of 56 weeks(P < 0. 05). Among the 10-week-old,19-week-old,56-week-old and 108-week-old groups,the types of non-neoplastic hepatic lesions detected in the female rats were 6,6,13 and 15 respectively,meanwhile those in the male rats were 6,6,13 and 15 respectively. Both male and female rats,the incidences of hepatocyte fatty degeneration,edema and hepatic infiltration of inflammatory cells were significantly increased with the increase of age in each group(P < 0. 05). The incidences of intrahepatic bile duct proliferation and intrahepatic bile duct fibrosis in rats at the age of 56 and 108 weeks were higher than those at the age of 10 and 19 weeks(P < 0. 008).Moreover,the frequency of hepatic sinus expansion lesions in rats at the age of 108 weeks was higher than those of 19 weeks(P < 0. 008). CONCLUSION: Spontaneous non-neoplastic lesions in the liver of SD rats were common,primarily demonstrated as hepatocyte fatty degeneration,edema and infiltration of inflammatory cells. The incidences of lesions increased with the increase of age.
