Objective: To explore the cognitive level and the mental status of the patients suffering from perimenopausal syndrome in Shanghai, and to identify the traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome. Methods: The cognitive level of the perimenopausal women was evaluated by using general living problem questionnaire. The mental status of the perimenopausal women was evaluated by using self-rating depressive scale. The traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome was identified by using traditional Chinese medical symptoms questionnaire. Results: A total of 634 perimenopausal women finished the investigation. There were 74.76% (474/634) patients who knew little about the perimenopausal syndrome; 77.29% (490/634) patients had a depressive tendency; 8.36% (53/634) patients had depressive disorder. There were 72.40% (459/634) patients who had the symptoms such as susceptibility to anger and restlessness, restless sleep at night, thirst with dry throat and bitter taste, and all these symptoms could be classified into hyperactivity of heart and liver fire syndrome. Conclusion: Patients suffering from perimenopausal syndrome know little about this disease and mostly have depressive tendency, and the major traditional Chinese medicine syndrome pattern is hyperactivity of heart and liver fire based on the chief clinical manifestations of the patients.

Objective To set internal quality control system of BCR-ABL(P210) transcript levels for real-time quantitative PCR (RQ-PCR).Methods Using K562 cells and HL-60 cells,we prepared high-and low-level BCR-ABL internal quality control substance.The BCR-ABL (P210) transcript levels of internal quality control substance have been determined for 184 times together with clinical samples from August 2013 to October 2015.The slope rate,intercept and correlation coefficient of standard curve were calculated according to different reagent lots (lots number 20130303,20131212,20140411 and 20150327 are called R1、R2、R3 and R4 for short respectively),and the detection results of quality control substance were calculated according to different reagent lots and quality control substance lots (lots number 20130725,20140611 are called Q 1、Q2 for short respectively).Then the results were analyzed by Levey-Jennings quality control chart combined with Westgard multi-rules theory.Results ①We analyzed the slope rate and intercept of standard curve.Fifty-three times of the R1 reagent detection,80 times of the R3 reagent detection and 14 times of the R4 reagent detection were all under control.For 37 times detection of R2 reagent,the slope rate was out of control for 6 times.It was lower than-x-s for the 2-8 tests and upper the average for the 12-37 tests.The intercept was out of control for 9 times,upper the-x+s for the 1-8 tests and lower the average for the 12-37 tests.②According to the detection results of quality control substance,for Q1 quality control substance,49 tests by R1 reagent were under control,and 1 out of 23 tests by R2 reagent was out of control.For Q2 quality control substance,14 tests by R2 reagent detection,72 tests by R3 reagent detection and 14 tests by R4 reagent were all under control.Conclusion The preparation of high-and low-level quality control substance using K562 and HL-60 cells was convenient and the detection results were reliable and stable.The application of quality control substance combined with slope rate and intercept in the internal quality control may contribute to quality assurance forquantitative detection of BCR-ABL (P210) transcript levels.

Objective:To understand the impact of diet on glycemic control in community-managed patients with type 2 diabetes mellitus (T2DM) and provide evidence for implementing prevention strategies and measures for diabetes patients.Methods:Eight communities were randomly selected from Changshu and Wuhan in 2015, and T2DM patients managed in the community were selected to conduct questionnaire surveys, physical measurements, and blood glucose testing. Factor analysis was used to obtain dietary patterns. A binary logistic regression model was used to analyze the factors affecting glycemic control.Results:Finally, 1 818 T2DM patients were included, and the control rate of FPG was 57.59% (95% CI: 55.30%-59.86%), and the control rate of 2 h postprandial blood glucose (2 h PBG) was 24.90% (95% CI: 22.93%- 26.91%). Five dietary patterns were obtained by factor analysis: animal food pattern, fruit-aquatic products-potato patterns, vegetable-grain pattern, egg-milk-bean pattern, and oil-salt patterns. No-conditional multivariate logistic regression analysis showed that after adjusting for confounding factors, the reduced probability of FPG control was related to animal food pattern ( OR=0.71, 95% CI: 0.52-0.98) and fruit-aquatic products-potato patterns ( OR=0.71, 95% CI: 0.51-0.97). The decrease in the 2 h PBG control probability was related to fruit-aquatic products-potato patterns ( OR=0.60, 95% CI: 0.40-0.90). The increased probability of FPG and 2 h postprandial glucose control were both related to vegetable-grain pattern ( OR=1.41, 95% CI: 1.03-1.94; OR=1.68, 95% CI: 1.13-2.51) and egg-milk-bean pattern ( OR=1.75, 95% CI: 1.25-2.46; OR=1.56, 95% CI: 1.00-2.42). Compared with the Q4 group of egg-milk-bean pattern, the FPG control rate of the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q2 group), egg-milk-bean pattern ( Q3 group)" was higher ( OR=6.79, 95% CI: 1.15-40.23, P=0.035). Compared with the Q4 group of vegetable-grain pattern, the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q3 group), egg-milk-bean pattern ( Q2 group), oil-salt pattern ( Q2 group)" had higher control rate of 2 h PBG ( OR=12.78, 95% CI: 1.26-130.05, P=0.031). Conclusions:A proper combination of dietary patterns and dietary patterns are more conducive to the control of FPG and 2 h PBG in T2DM patients managed in the communities of Wuhan and Changshu. Patient nutrition education should be strengthened, and the food-matching ability of patients should be improved.

Objective To explore the problems of health poverty faced by a special group of people with disabilities and the difficulties in the practice of health poverty alleviation, so as to provide a scientific basis for the health poverty alleviation of the disabled. Methods A self-made questionnaire was used for one-to-one survey, and a database was established by Excel. SPSS was used for descriptive analysis and horizontal comparison. Results The participation rate of basic medical insurance for the disabled was relatively high (93.40%), and the medical insurance payment was mainly paid by individuals (70.13%). The satisfaction of medical insurance was low (43.12%), and 84.64% of the disabled thought that their medical expenses were high. 45.22% of the families of disabled patients met the universal standard of catastrophic health expenditure. Compared with Shandong Province, the basic medical insurance coverage rate of the disabled in Hubei Province was slightly lower, the satisfaction rate of medical insurance was higher, and the proportion of catastrophic health expenditure of families was larger. The analysis of the results showed that the disabled people with a lower disability level, children and middle-aged with disabilities, the disabled people with less or more family members, and the disabled people without the minimum living subsistence allowances were not satisfied with the medical insurance. Conclusion The basic medical insurance in the two places has alleviated the difficulty of medical treatment for the disabled to a certain extent, but the family burden of diseases of the disabled was still heavy. The level of medical security for people with disabilities should be improved, and their economic burden of disease should be reduced, so as to improve the satisfaction of medical insurance.
