Objective To investigate the relation between paraoxonase (PON) 1 Q191R gene polymorphism and type 2 diabetes mellitus complicated with hypertension. Methods Genomic DNA was extracted from peripheral blood leukocytes. The studied DNA was amplified by PCR, and then digested with the restriction endonuclease AlwⅠ and separated on 2% agarose gel electrophoresis. PON activity was estimated by spectrophotometer. Serum insulin and C-peptide were measured by radioimmunoassay. Results The frequencies of QQ genotype and Q allele in type 2 diabetes mellitus with hypertension group were significantly higher than those in type 2 diabetes mellitus group (P

Objective To determine whether the paraoxonase2 (PON2) gene A148G polymorphism is associated with the pathogenesis of nephropathy in type 2 diabetes mellitus patients (DN) . Methods PON2 genotype distribution and allele frequency were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) . Serum immune reactive insulin (IRI) and C-peptide (C-P) concentrations were measured by radioimmunity. Results GG genotype and G allele frequency were higher in DN group than that in simple type 2 diabetes mellitus group (x2 =4. 26 P

Objective To investigate the clinical effects of gliclazide sustained-release tablet for recently diag-nosed type 2 diabetes mellitus. Methods 118 subjects with recently diagnosed type 2 diabetes and normal figure were divided into three groups. The three group subjects used gliclazide sustained-release tablet, repaglinide(import-ed) ,novolin 30R for 12 weeks,respectively. For all pretherapy and post-treatment cases, blood glucose and glycosy-lated hemoglobin were tested before meal. After two hours of meal, blood glucose was tested again. Meanwhile, hypo-glycaemia event was inspected. The test results were analyzed by "mean ± standard deviation" method. Results There are no significant difference(P>0.05) in fasting blood sugar and postprandial blood sugar(2h) level between the group using gliclazide sustained-release tablet and the group using novolin 30R. The clinical effects of both gli-clazide sustained-release tablet and novolin 30R to fasting blood sugar are all better than that of repaglinide(import-ed) (P < 0.01). But there are no significant difference in postprandial blood sugar(2h) level between the group of us-ing gliclazide sustained-release tablet and the following two group: repaglinide(imported) and novolin 30R. Conclu-sion The investigation results show that gliclazide sustained-release tablet is better than repaglinide(imported) in fasting blood sugar. But for the effects of postprandial blood sugar(2h), there is no significant difference between gli-clazide sustained-release tablet, repaglinide(imported) and novolin 30R.

Objective To investigate the effect of hyperurieemia on cardiovascular and cerebrovaseular complications in type 2 diabetes mellitus(T2DM). Methods According to the level of blood uric acid,430 patients with T2DM were divided into hyperuricemia group and non-hyperurieemia group, the differences of uric acid(UA) ,creatine(Cr) ,total cholesterol(TC) ,triglyeride(TG) ,fasting blood glucose(FBG) ,glycosylated hemoglobin(HbA1c) and body mass index(BMI) were compared,and the occurrences of coronary heart disease, hypertension and acute cerebrovascular accidence were observed. Results The FBG and HbAIc were not significantly different between the two groups(P＞0.05). The BMI ,TG,TC and Cr in the hyperurieemia group were significantly higher than those in the non-hyperuricemia group(P＜0.05 ). The incidence rates of coronary heart disease, hypertension and acute cerebrovascular diseases in the hyperuricemia group were also significantly higher than those in the non-hyperuricemia group (P＜0.05 ). Conclusion Hyperuricemia is obviously correlated with obesity and blood lipid abnormalities. Hyperurieemia can aggravate the metabolic disturbances,and can accelerate the occurrence and development of cardiovascular and eerebrovascular diseases in the patients with T2DM.

AIM: To observe the effect of Shenmai injection,a chinese medicine,on apoptosis of cardiac myocytes after hypoxia.METHODS: Cardiac myocytes were separated from neonate rat heart and cultivated in vitro.Hypoxia condition was induced by mixture of 95%N2 and 5%CO2.Cells were exposed to hypoxia for 6 h or 12 h and treated with Shenmai injection(5 mL/L) from 24 h before hypoxia until the end of hypoxia.First,apoptosis was detected with Annexin V-FITC and PI staining by flowcytometry.Then,the activity of cardiac myocyte mitochondria was observed by MTT method.Mitochondria membrane potential and the activity of caspase 3,7 were also measured by laser scan microscopy and multi-detection microplate reader,respectively.RESULTS: The apoptotic cells became more and more with prolonged hypoxia.Shenmai injection enhanced mitochondria activity,kept membrane potential,inhibited the activation of caspase3,7 and then decreased apoptotic cells(P

Objective To investigate the value of dual-source CT perfusion imaging in evaluation of liver fibrosis stage.Methods Liver fibrosis models were established with 35 rabbits (experimental group)which were intraperitoneally injected with carbon tetra-chloride.Meanwhile,other 5 rabbits were regarded as control group which were intraperitoneally inj eced with physiological saline.7 rabbits of experimental group and 1 of control group were undergone dual-source CT perfusion scan at 4,6,8,10,12 weeks respec-tively.Arterial liver perfusion (ALP),portal venous perfusion (PVP),total hepatic perfusion (THP),hepatic perfusion index (HPI)were recorded,and staging of liver fibrosis were assessed by pathological method.Results With the increase of liver fibrosis degree,HPI showed an upward trend,whereas PVP was opposite.HPIs of S2,S3 and S4 stage were significantly different com-pared to that of control group respectively.The differences of HPI between S3,S4 stage to S0 and S1 stage were significant.PVP between S2,S3,S4 stage to S0 stage and S1 stage were also significant different.Conclusion HPI and PVP can reflect the perfu-sion changes of liver fibrosis stages.Combination of HPI and PVP may help the diagnosis of S2,S3 or S4 stage of liver fibrosis.

Objective To investigate the value of X-ray,CT and MRI in diagnosing early spinal tuberculosis by constructing lum-bar vertebra tuberculosis model in New Zealand rabbits.Methods Forty healthy New Zealand rabbits were randomly divided into the infected group (n=30)and the control group (n= 10).All rabbits were performed lumbar vertebra surgery,and then underwent imaging and histopathologic examination at 4,6,8 weeks respectively.Results The sensitivity of X-ray,CT and MRI in detecting tuberculosis lesions were 46.13%,76.3%,and 92.3%,respectively.MRI and CT were better than X-ray for displaying the de-struction range limited in a single vertebra (P <0.05).Combination with routine MRI and diffusion-weighted imaging (DWI)could find the vertebra tuberculosis at the early stage.According to the HE staining,pus cells,epithelioid cells or necrosis were seen in the tissue sections of vertebra and paraspinal soft tissues in the infected group.Conclusion X-ray,CT and MRI could provide some information for the early diagnosis of spinal tuberculosis,and MRI is more sensitive.
