ObjectiveTo investigate the radioactive level of gross alpha and beta in drinking water in one district in Shanghai and provide a scientific basis for measuring the level of radiation in case of drinking water pollution due to potential nuclear accidents. MethodsA total of154 samples collected across the district were monitored by using the standard examination method for drinking water - radiological parameters GB/T 5750.13-2006. ResultsAll the samples of the drinking water conformed to the standard for drinking water quality GB 5749-2006. The differences between different seasons were significant. The difference of gross alpha and beta radioactivity of drinking water was significant between the high water period and the dry water period. The former was higher than the latter. ConclusionIt is very important to monitor and study radioactivity of drinking water regularly for the prevention and control of health damage caused by radioactive water pollution.

Objective:To evaluate the association of HbA 1C level and variability with annual decline in glomerular filtration rate in elderly patients with type 2 diabetes. Methods:A total of 527 elderly type 2 diabetic patients with baseline estimated glomerular filtration rate(eGFR)≥60 mL·min -1·(1.73 m 2) -1 at the diabetes center of a tertiary hospital in Jiangsu province were included and followed up. The mean value and the variability of HbA 1C, including standard deviation(HbA 1C-SD), variation coefficient(HbA 1C-CV), and adjusted standard deviation(Adj-HbA 1C-SD) were calculated. According to the annual decreased rate of eGFR, the patients were divided into △eGFR>5% group and △eGFR≤5% group. Cox proportional risk regression model was used to evaluate the relationship between HbA 1C variability and the risk of decreased glomerular filtration rate. Results:With a mean follow-up time of 19 months, there were 176 patients whose △eGFR>5%. Compared with △eGFR≤5% group, the HbA 1C-mean and HbA 1C variability were significantly higher in △eGFR>5% group( P<0.05). Cox regression analysis showed that HbA 1C-mean, HbA 1C-SD, HbA 1C-CV, and Adj-HbA 1C-SD were significantly correlated with decreased glomerular filtration rate. After adjustment for age, gender, HbA 1C-mean, and other factors, only Adj-HbA 1C-SD was correlated with renal insufficiency [ HR=3.32(1.68-6.57)]. Conclusions:HbA 1C variability is independently associated with annual decline in glomerular filtration rate in elderly patients with type 2 diabetes. The Adj-HbA 1C-SD is the most sensitive indicator in predicting decreased glomerular filtration rate.

OBJECTIVE：To analyze th e general characteristics and application of the models used in the pharmacoeconomic evaluation of type 2 diabetes mellitus （T2DM）therapy during the past 5 years，and to provide reference for the selection and improvement of T 2DM pharmacoeconomic model. METHODS ：Retrieved from PubMed ，Embase，CNKI，Wanfang database and VIP during Jan. 1st，2015 to Dec. 31st，2019，pharmacoeconomic evaluation literatures about T 2DM therapy were collected ；the included model was analyzed in respects of general structure ，therapy plan establishment ， short-term therapeutic efficacy ， complication simulation ，model effectiveness validation ，application frequency. RESULTS ：A total of 81 literatures were included ， involving 14 models，such as CORE model ，Cardiff model ，ECHO model ，etc. Mostly ，Markov or micro Markov simulation method were adopted to measure the patient ’s lifetime health outcome and cost mostly from the point of view of third-party payer. Seven models could simulate 2-4 therapy plans ；short-term efficacy mainly included risk factors of diabetic complications （such as glycosylated hemoglobin level and body mass ）and adverse drug reactions. Most models used intermediate indexes to simulate the occurrence of complications ，and the number of complications ranged from 3 to 15；the validity of model effectiveness included surface validity ，internal validity and external validity ，etc. Among 14 models，the most frequently used models in the past 5 years were long-term models that had been validated ，among which CORE model had the most application times （38/81，46.91％）， followed by Cardiff model （12/81，14.81％）. CONCLUSIONS ：The 14 models have similar structure. The differences of the models are mainly reflected in 3 aspects as therapy plan setting， considered short-term efficacy ， the number of model are ideally choose based on available evidences.

OBJECTIVE：To evaluate the economics of first-line therapy drug for metastatic renal cell carcinoma （mRCC）as sunitinib，sorafenib and pazopanib ，and to provide reference for the adjustment of medical insurance list and clinical medication decision. METHODS ：Using“metastatic renal cell carcinoma ”“mRCC”“sunitinib”“sorafenib”“pazopanib”“cost-effectiveness” “cost-utility”“cost-benefit”“economic analysis ”as the Chinese and English retrieval words ，relevant literatures published during Jan. 1st，2006 to Jul. 15th，2019 were retrieved from PubMed ，Web of Science ，the Cochrane Library ，CNKI，Wanfang database ， VIP. The literatures were screened according to inclusion and exclusion criteria . The quality of the included literatures was evaluated with CHEERS scale. The effectiveness and economy of sunitinib ，sorafenib and pezoparib in the treatment of mRCC were compared qualitatively after the relevant data were extracted. RESULTS ：A total of 10 literatures were included ，and the total coincidence rates of 7 literatures over 75.00％. Among the 4 literature studies of sulatinib vs. sorafenib ，3 literature studies pointed out that sulatinib was the absolute advantage scheme ，and 1 literature study pointed out that sorafenib was more economical ； among the 6 literature studies of sunitinib vs. pezoparib ，4 literature studies indicated that pezoparib was the absolute advantage scheme，and 2 literature studies indicated that sunitinib was more economical. CONCLUSIONS ：In most cases ，the efficacy and economy of pezoparib in the treatment of mRCC is better than sunitinib and sorafenib ，but real world data shows that sunitinib is more economical.

Objective To study the effects of dynamic,support-inducing exercise on the support,balance and gait ability of patients with moderate-to-severe hemiplegia after stroke.Methods Fourteen stroke patients were randomly assigned to an experimental or a control group (7 cases to each).The patients in the experimental group received both dynamic,support-inducing exercise and routine exercises,while the patients in the control group received routine exercises only.Before training and after 40 and 60 days of training,their functional capacity was evaluated with the Chinese stroke scale (CSS) for neurological deficits,Berg's balance scale (BBS) and using functional ambulation categories (FACs).Results Before training there was no inter-group difference in average CSS or BBS scores or in FACs.For the experimental group there were significant intra-group differences compared with 0th day in all three items at both time points.At days 40 and 60 there were also significant intra-group differences in BBS scores and FACs in the control group,and CSS scores improved significantly only in the experimental group.At day 40 there were significant inter-group differences in average CSS,BBS and FAC results.However,by day 60 a significant difference persisted only in average CSS scores.Conclusions Dynamic,support-inducing exercise can improve support,balance and gait in patients with moderate-to-severe hemiplegia after stroke.
