Objective To investigate the association between ankle-brachial index (ABI) and serum uric acid (SUA) level in patients at high risk of cardiovascular diseases .Methods Three hundred and sixty-three patients with hypertension and diabetes mellitus (DM ) were divided into hyper-tension group (n=189) ,hypertension plus DM group (n=123) ,and DM group (n= 51) .Their ABI was assayed ,SUA level was measured ,and other risk factors for cardiovascular diseases were detected such as BMI ,systolic and diastolic pressure ,serum levels of TG ,TC ,HDL-C ,LDL-C and HbA1c .Association of SUA level and ABI with other clinical indexes was analyzed by partial cor-relation analysis .Results The systolic and diastolic pressure ,serum levels of TG ,HDL-C and HbA1c were significantly different in 3 groups (P<0 .05) .The ABI was significantly higher in hypertension group and DM group than in hypertension plus DM group ,and negatively related with SUA level after adjustment for hypertension and DM history ,age ,gender ,BMI ,serum levels of TG ,TC ,HDL-C ,LDL-C and HbA1c ,systolic and diastolic pressure (r= -0 .235 ,P=0 .012) . Conclusion ABI is associated with SUA level in patients at high risk of cardiovascular diseases .

Objective:To isolate the genes induced by Ty21a. Methods: Prepare the intestinal cells of Balb/C mouse with and without Ty21a immunization, extract the polyA+ RNA, synthesize the dscDNA by using reverse transcription-PCR,get the differentially expressed genes by suppression subtractive hybridization(SSH).Results:Seven genes were novel genes revealed by GenBank searching whose expression were probably induced by Ty21a were isolated by SSH and cDNA microarray. The full length cDNA sequence of three genes are now obtaining through RACE-PCR. Conclusion: SSH is an effective method for isolating the differentiatlly expressed genes; High throughput cDNA microanay is a credibility method to profile changes in gene expression; Ty21a can induce the expression of some new genes related to immune.

To increase the biotransfomation efficiency from the orotic acid to the uridine 5'-monophosphate(UMP),URA5 gene encoding orotate phosphoribosytransferase was amplified from Saccharomyces cerevisiae BY4742 by PCR,then it was inserted into the expression vector pYX212(contained orotidine monophosphate decarboxylase gene URA3)and the pYX212-URA5 was transformed into Saccharomyces cerevisiae BJX12 by electroporation.The recombinant strain was elementarily used to convert orotic acid to UMP.The results showed that pYX212-URA5/BJX12 could accumulate 7mmol/L UMP from 32mmol/L orotic acid in 26h,significantly higher than both control groups pYX212/BJX12(2.7mmol/L) and BJX12(2.4 mmol/L).

Objective To investigate the efficacy of statin on carotid plaque stability in elderly patients assessed by K trans (the combination of E and F) of dynamic contrast material enhanced (DCE) magnetic resonance (DCE MR) imaging.Methods 37 elderly patients with carotid artery of low echo or mixed echo plaque in carotid artery patches were screened by B type ultrasound.According to the standard of 2011 ESC/EAS guidelines,all patients were divided into two groups:normal level of LDL-C group achieving LDL-C target and high level of LDL C group not achieving target of LDLC.Plaque area and size of lipid-rich necrotic core were measured by 3.0T enhancement magnetic resonance,and K trans was measured by DCE-MR dynamic contrast material enhanced (DCE) magnetic resonance (MR) imaging.and serum hs-C-reactive protein level was detected within 1 week.Results Plaque area,size of lipid-rich necrotic core,ratio of lipoid core over plaque area,K trans and serum level of hs-CRP were less in normal LDL-C level group than in high LDL-C level group [(2.06±0.45) mm2 vs.(3.63±0.62) mm2,(0.52±0.05) mm2 vs.(1.49±0.01) mm2,2 cases (11.8％) vs.14 cases (70.0％),(0.041±0.009) min1 vs.(0.079±0.011) min-1,(1.60±0.27) mmol/L vs.(2.80 ± 0.34),all P＜0.05].Linear regression analysis revealed that there was no significant correlations of K trans with the size of lipid necrotic core (r=0.19,P＞0.05) and hs-CRP (r=0.23,P＞0.05).Conclusions Dynamic contrast material enhanced (DCE) magnetic resonance (MR) imaging is a quantitative method assaying atheromatous plaque components; K trans may be a new indicator to measure the stability of plaques; Statin can stabilize plaques through inhibiting the proliferation of Vasa vasorum in plaque angiogenesis,anti-inflammatory and reducing the size of lipidrich necrotic core.

Objective To investigate the mutations of CLCNKB gene in a family with classic Bartter syndrome. Methods Genetic DNA was extracted from peripheral blood leucocytes of family members.The coding exons and intron exon junctions of CLCNKB gene were amplyfied by PCR and sequenced directly.Fifty unrelated healthy subjects were selected to exclude the possibility of polymorphism. Results A heterozygous(missense)mutation(482T>G,L161R)was detected in the exon 4 of patients.The hetemzygous mutation(L161R)was found in the mother,while no mutation was found in the father of this family.L161R had not been reported and was a novel mutation when referring to literatures and human genomic database home and abroad.Conclusion A new CLCNKB gene mutation(L161R)is identified for the first time.

AIM: To assess the prophylactic effect of lumbrokinase plus aspirin on recurrence of ischemic stroke in the patients recovering from cerebral infarction. METHODS: 87 patients of cerebral infarction were assigned to two groups:control and treatment group,treated respectively with aspirin in control group and lumbrokinase plus aspirin in the treatment group.The recurrence rate and clinical efficacy were analysed. RESULTS: There were remarkable differences in recurrence rate and clinical efficacy between the two groups(P
