Objective: To investigate the therapeutic effects of compound Kushen Tang and its relevant mechanism in TNBS-in-duced ulcerative colitis ( UC) rats. Methods:UC was induced by TNBS in rats. After compound Kushen Tang was given orally, the levels of MDA, iNOS, and NO and the activity of MPO, SOD, and GSH-Px were measured. The general condition of rats and colon tissue morphology were observed. Results:The levels of MDA (P<0. 05), iNOS (P<0. 01) and NO (P<0. 01) and the activity of MPO (P<0. 01) in tissues of UC rats were significantly higher than the control group. The activity of SOD (P<0. 01) and GSH-Px (P<0. 05) were significantly lower than those in the control group. After the treatment with high doses of compound Kushen Tang, the levels of MPO (P<0. 01), MDA (P<0. 05), iNOS (P<0. 05) and NO (P<0. 01) were significantly decreased, and the activity of SOD (P<0. 01) and GSH-Px (P<0. 05) significantly increased. The therapeutic effect was dose-dependent and the general con-dition of rats and colon tissue morphology were also significantly improved. Conclusion:Compound Kushen Tang is considered as a no-vel therapeutic alternatives for the treatment of UC, which can reduce coloni inflammatory injury and ameliorate the colitis.

Objective:To analyze and compare the association between different obesity-related indices and vitamin D deficiency in middle-aged and elderly population dwelled in Lanzhou city.Methods:From May, 2011 to September, 2012, middle-aged and elderly individuals with complete baseline data were included via randomly cluster sampling from 3 communities in Lanzhou. The subjects were divided into 4 subgroups by vitamin D levels and various obesity-related indices were compared across subgroups with the same gender. The relationship between the obesity-related indices and the severity of vitamin D deficiency was analyzed using Spearman correlation analysis, and the effects of different obesity-related indices on the severity of vitamin D deficiency was analyzed using multivariate logistic regression analysis.Results:A total of 9 437 residents were included. The overall prevalence of vitamin D deficiency was 97.7%. Compared with the group with lower vitamin D level, participants in the group with higher vitamin D level showed evidently lower body mass index (BMI), waist circumference (WC), lipid accumulation product (LAP), visceral adiposity index (VAI) and triglyceride/ high density lipoprotein cholesterol (TG/HDL-C) ratio in the total population and females, while only WC, LAP, VAI and TG/HDL-C in the males (all P<0.05). Spearman correlation analysis showed that BMI, WC, LAP, VAI and TG/HDL-C were positively correlated with the severity of vitamin D deficiency in the total population and the females, while only LAP, VAI and TG/HDL-C in the males (all P<0.05) . Multivariate logistic regression analysis showed that higher levels of these obesity related indices were correlated with more severe vitamin D deficiency in the total population and the females, while only higher LAP, VAI and TG/HDL-C in the males (all P<0.05). The effects of higher LAP was the most prominant in the total population ,the females and the males. Conclusion:Various obesity phenotypes are closely related to vitamin D deficiency in middle-aged and elderly women, while only visceral obesity and abnormal lipid metabolism are related to vitamin D deficiency in middle-aged and elderly men, with LAP being the most important influencing factor.

OBJECTIVE To evaluate the palatability and chewability of chewable tablets, and provide reference for the quality evaluation of various types of chewable tablets. METHODS Using self-made Glucosamine hydrochloride chewable tablets as the model drug, the quality test was conducted. The in vitro simulation system for chewable tablets was established by using a texture analyzer and rheometer, and an oral simulation experiment was conducted on chewable tablets. The texture analyzer was used to measure the force required for chewing and simulate the static disintegration process of chewable tablets; the rheometer was adopted to measure the viscoelasticity, thixotropy, and deformability of chewable tablets during the chewing process. RESULTS The disintegration time limit, principal component content, and dissolution of self-made Glucosamine hydrochloride chewable tablets all met the limit requirements. The in vitro simulation results of the texture analyzer showed that self-made chewable tablets were easy to chew in both axial and radial directions, and the force required for chewing was within the range of the chewing force of the teeth; chewable tablets could disintegrate at an appropriate time without being chewed and only taken in the oral cavity. The in vitro simulation results of the rheometer showed that the chewable tablets in the oral cavity exhibited a behavior of elasticity as the main factor and viscosity as the secondary factor through the continuous stirring of the tongue, and the viscosity of the chewable tablets gradually decreased with tongue stirring or tooth chewing; when chewing with teeth, the internal force of the chewing tablets decreased, causing plastic deformation and crushing. After being crushed, the shape couldn’t be restored, making it easy to chew and swallow. CONCLUSIONS The combination of texture analyzer and rheometer can be used to simulate the oral chewing process and evaluate the palatability and chewability of self-made Glucosamine hydrochloride chewable tablets. This model can provide reference for the evaluation of various chewable tablets.

OBJECTIVE:
To explore the correlation of different glucose metabolism statues with chronic kidney disease (CKD) in middle-aged and elderly individuals in Lanzhou.
METHODS:
Based on the baseline data of REACTION Study in Lanzhou area, we randomly sampled 10 038 residents aged 40-75 years in 3 communities in Lanzhou, who were classified into normal glucose tolerance (NGT), impaired glucose regulation (IGR) and diabetes groups. The estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (ACR) were used to assess the renal function and albuminuria, respectively. Binary logistic regression was performed to analyze the contribution of the risk factors to CKD. Polynominal regression was used to determine the trends of eGFR with the increment of ACR.
RESULTS:
Among all the participants, the prevalences of albuminuria, CKD and renal insufficiency (RI) were 26.2%, 27.4% and 2.5%, respectively. The prevalence of albuminuria, CKD and RI were significantly higher in the diabetes group than in IGR and NGT groups (
CONCLUSIONS
Diabetes mellitus is a significant risk factor for albuminuria and RI, while IGR is not. Screening for albuminuria and eGFR is highly recommended for individuals with diabetes, hypertension, and obesity, especially in women and the elderly population.
