OBJECTIVE:To investigate the efficacy of rosiglitazone in the treatment of patients with nonalcoholic fatty liver(NAFLD).METHODS:A total of 124 patients with NAFLD(excluding those with cirrhosis) were randomly divided into rosiglitaone(RSG) treatment group and placebo group(control) for a treatment of 24wk.Then the curative effects in two groups were compared.RESULTS:As compared with placebo,RSG showed a better efficacy in the improvement of the liver function,levels of blood glucose and blood lipid(P

OBJECTIVE: To discuss the the control of hyperglycemia in patients with severe acute pancreatitis(SAP).METHODS: Patients were treated with NPH(subcutaneous injection) or continuous subcutaneous insulin injection(CSII) or Insulin glargine(subcutaneous injection).Incidences of hypoglycemia and hyperglycemia and the blood sugar level within 5 days of admission were measured.RESULTS: The incidences of blood glucose level being ≤4.0 mmol?L-1 or ≥11.1 mmol?L-1 were significant different in CSII group and insulin glargine group compared with NPH group respectively(P

ObjectiveTo investigate the correlation between serum C-reactive protein(CRP),tumor necrosis factor-alpha(TNF-α) and atherosclerosis in patients with subclinical hypothyroidism.Methods Seventy-five patients with subclinical hypothyroidism were divided into two groups according to the level of TSH:mild group (42 cases) with TSH between 5.5 and 10.0 mU/L and severe group (33 cases) with TSH ＞10.0 mU/L.Thirty healthy physical examinees or volunteers were selected as control group.TG,LDL-C,HDL-C,TSH,FT4,FT3,CRP,TNF-α and carotid intima-media thickness(CIMT) of all cases were detected and measured.ResultsCIMT of mild,severe and control groups were(0.88 ± 0.20),( 1.12 ±0.21 ),(0.62 ±0.21 ) mm,respectively.CIMT of mild and severe groups were both significantly higher than that of control group,CIMT of severe group was significantly higher than that of mild group (P ＜ 0.01 ).There were no significant differences of CRP and TNF- α among three groups (P ＞ 0.05 ).LDL-C of mild and severe groups were significantly higher than that of control group [ (3.22 ± 0.37),(3.49 ± 0.38 ) mmol/L vs.(2.48 ±0.41 )mmol/L,P ＜0.01 ].HDL-C and TG between mild and control groups had no statistical significance (P ＞0.05).Compared with control and mild groups,HDL-C of severe group decreased [(0.92 ±0.10)mmol/L vs.( 1.21 ± 0.14),( 1.17 ± 0.11 ) mmol/L] and TG increased [ ( 1.50 ± 0.49) mmol/L vs.( 1.11 ±0.53),(1.27 ±0.47) mmol/L](P＜ 0.01 or ＜ 0.05).The levels of TG,LDL-C,TSH,CRP and TNF-α had positive correlation with CIMT (r =0.52,0.37,0.48,0.39,0.45;P ＜0.05 or ＜0.01 ).FT4 was negatively correlated with CIMT (r=-0.24,P＜0.05).HDL-C had no relation with CIMT (r =0.06,P ＞0.05).ConclusionsThere are many abnormalities such as metabolism disorder of blood lipid in patients with subclinical hypothyroidism.The risk of atherosclerosis increases in these patients and inflammatory reaction may not be an important factor of subclinical hypothyroidism complicated with atherosclerosis.

AIM To establish an LC-MS/MS method for the simultaneous content determination of paeoniflorin,albiflorin,neochlorogenic acid,chlororogenic acid,catechin,epicatechin,ethyl gallate,danshensu,ferulic acid,caffeic acid,gallic acid,protocatechuic acid,protocatechualdehyde and rosmarinic acid in Yangxue Qingnao Granules (Angelicae sinensis Radix,Chuanxiong Rhizoma,Paeoniae Radix Alba,etc.).METHODS The analysis of methanol extract of this drug was performed on a 20 ℃ thermostatic Waters Symmetry Shield RP C18 column (3.9 mm × 150 mm,5 μm),with the mobile phase comprising of acetonitrile-water (containing 0.1％ formic acid) flowing at 0.4 mL/min in a gradient elution manner.RESULTS Fourteen constituents showed good linear relationships within their own ranges,whose average recoveries were 85.5％-107.0％ with the RSDs of 2.0％-5.0％.CONCLUSION This simple,sensitive,accurate and reproducible method can be used for the quality control of Yangxue Qingnao Granules.

Objective To investigate the level of insulin and amyloid beta-protein (Aβ) in patients with Alzheimer disease(AD). Methods The levels of fasting plasma glucose, true insulin, C-peptide, Aβ40 and Aβ42 in 70 healthy age-matched adults and 55 patients with AD were measured and analyzed. Results No differences were observed for the levels of fasting plasma glucose between AD groups and normal group (P>0.05). The level of the true insulin and C-peptide of the moderate/severe AD group were significantly higher than that of the normal control group(P<0.05), as well aw that of the Aβ40 (P<0.05). The level of Aβ42 of the mild AD group waw significantly higher than that of the normal control group(P<0.01). Conclusion Plasma insulin and Aβ are abnormal in AD, and they are related to severity of dementia.

Objective To investigate the relationship of lacunar infarction (LI) and white matter lesion with cognitive impairment in patients with subcortical ischemic vascular disease (SIVD) Methods Fifty-three patients were diagnosed as SIVD according to the criteria of Erkinjuntti. The symptoms and signs were recorded by an interview and examination, and neuropsychological assessment and magnetic resonance imaging (MRI) were performed. A semi-automated MRI quantitative method was used to measure the volume of white matter hyperintensity (WMH) and the number of LI was counted. Correlation and the partial correlation analysis were performed to examine the relationship of general cognitive function with the volume of WMH and the number of LI. Results The pseudobulbar paralysis symptom and the upper motoneuron injury sign were the most common in these patients (18.9% and 37.7%). Correlation analysis showed that there was positive correlation between the volume of WMH and age (r = 0. 518, P < 0. 05), and there was negative correlcction between mini-metal state examination (MMSE) scures and the volume of WMH (r=-0.514, P<0. 05), After controlling confounding factors, only age was positively correlated with the volume of WMH (r=0. 400, P=0. 004). There were negative correlation between the number of LI, the volume of WMH and MMSE scores(r=-0. 456,-0. 514,-0. 385,-0. 382;all P<0. 05), and the years of education was positively correlated with MMSE scores (r= 0. 518, P< 0. 001). Conclusions Age may not be the main risk factor for cognitive impairment in patients with SIVD. The volume of WMH and the number of LI are independent risk factors for cognitive impairment in patients with SIVD. Patients with severer SIVD or more LI show poorer performance on cognitive function.

Traditional Chinese Medicine (TCM) products could be registered as natural health products (NHPs) in Canada. Its registration process could be mainly divided into simple-application, traditional-application and non-traditional application. By analyzingi the TCM registration evidence system and its safety, effectiveness and quality required by different registration categories in Canada, we found that "simple-application" procesure needs to submit evidence based on the parameters of a component in the monograph. As for "traditional application", TCM products need to be used at least 50 years with, traditional material or Pharmacopoeia can be used as evidence; As for non-traditional application, TCM products need to provide evidence according to the disease risk level, and most of them need to provide scientific experiment evidence. Therefore, from the experience of TCM registration evidence system in Canada, the registration of TCM products should pay attention to improve the its classification method, refining its evidence requirements and data types, promoting the formulation of monograph of TCM, realizing the scientific evaluation and rapid review of classic famous prescriptions, and promoting the inheritance and innovative development of TCM in China.
