OBJECTIVE： Using PCR methodology and agarose electrophoresis to detect PAI-1 4G/5G promoter polymorphism in patients with recurrent cerebral infarction in the North Jiangsu Province of China, and to compare results with healthy subjects and patients with first-occurrence cerebral infarction in the same region. DESIGN, TIME AND SETTING： Non-randomized, concurrent, control trial. A total of 122 cerebral infarction patients were admitted to Xuzhou Medical College Hospital＇s Department of Neurology and Xuzhou Central Hospital＇s Department of Neurology between July 2003 and August 2006. PARTICIPANTS： The patients consisted of 63 males and 59 females, aged （62 ± 10） years. They were divided into first-occurrence （n = 58） and recurrence （n = 64） groups. In addition, 50 healthy subjects that underwent physical examination in the outpatient department, including 26 males and 24 females, aged （60 ±12） years, were selected as controls. METHODS AND MAIN OUTCOME MEASURES： PAl-1 4G/5G promoter polymorphism was detected and analyzed using PCR methodology and agarose electrophoresis. RESULTS： Significant differences were determined in terms of genotypic frequency and allele frequency of PAI-1 4G/5G promoter polymorphism, in patients with first-occurrence or recurrent cerebral infarction, when compared with healthy subjects （P 〈 0.05）. There was, however, no significant difference between the first-occurrence and recurrence groups （P 〉 0.05）. CONCLUSION： PAl- 1 4G/5G promoter polymorphism is genetic risk factor for cerebral infarction in China. However, it may be associated with recurrence of cerebral infarction in patients from the North Jiangsu Province of China.展开更多

The aim of the study was to examine the determinants of plasma PAI-1 Ag level among type 2 diabetes patients. Methods: 491 Tunisian type 2 diabetes patients had clinical evaluation (weight, high, BMI, Waist Circumference), laboratory investigations including FBG Hb1Ac, cholesterol, triglyceride;HDL-cholesterol was done;plasma PAI-1 antigen level was done with ELISA;−675 4G/5G and −844 G/A polymorphisms of PAI-1 gene was done by PCR-ASA and PCR-RFLP respectively. Results: The mean age for our patients was 58.3 ± 10.5 years;sex-ratio = 0.92;mean PAI-1 level was 34.6 ± 21.3 ng/ml. We didn’t find correlation between PAI-1 level and BMI, but we have found significant correlation between PAI-1 and waist circumference (p = 0.032), most enhanced in men (P = 0.002), T2D patients who have FBG > 11 mmol/l had PAI-1 Ag level higher than those who have FBG P = 0.034), but no difference found between T2D with high Hb1Ac > 8% and those with Hb1Ac < 8%, significant correlation was seen between PAI-1 level and LDL-cholesterol (P = 0.05), high correlation between PAI-1 Ag level and −675 4G/5G polymorphism genotype was seen, 4G/4G carriers had the highest PAI-1 level, 4G/5G had intermediary level and 5G/5G had the lowest level (P −844G/A polymorphism genotypes. Using multiple variable linear regression analysis, the independent factor associated with plasma PAI-1 level was −675 4G/5G polymorphism (regression coefficient β = 4.6, P Conclusion: the present study identifies −675 4G/5G not −844 G/A polymorphism of PAI gene as the principal determinant of plasma PAI-1 level in Tunisian T2D patients, the android fat distribution, dyslipidemia and hyperglycemia play a modest role in this variation.展开更多

Methods: Ninety cases of type 2 diabetes mellitus inpatients were selected, and randomly divided into LG small dosage group (SDG), LG large dosage group (LDG) and control group. The 120 mg LG, 400 mg LG and normal saline 250 ml were given through intravenous dripping respectively, once daily, 20 days as one treatment course. Before and after treatment, all the patients had their fasting blood taken for PAI-1 and tissue plasminogen activator (t-PA) assessment test to perform the comparative study. Results:Seventy-three out of the 90 patients completed the observation course, the PAI-1 activity of three groups after treatment all lowered compared with that before treatment, and the difference between groups was also significant (all P<0. 01). After treatment the PAI-1 level of SDG and LDG of LG were all markedly lowered (all P<0. 01), the LDG's lowering was more evident than that of SDG, and comparison between these two groups of patients showed significant difference (P<0. 01). Although in the control group there was some difference between before and after treatment, it was not so significant like the above-mentioned two groups (P = 0. 0140). No adverse reaction occurred in the 3 groups during the observation period. Conclusion:LG could safely and effectively lower type 2 diabetes mellitus patient's plasma PAI-1 activity level, and LDG of LG proved to be particularly effective.展开更多

Results: Higher frequencies of The genotypes 4G/4G (p = 0.01) and 4G/5G of polymorphism −675 4G/5G were seen in diabetic (p = 0.05) and higher frequencies of 5G/5G was seen in controls (p −844 G/A was seen in diabetics and G/G was seen in controls (p = 0.01). Conclusion: Our study found association between 4G allele of −675 4G/5G and A allele of −844 G/A of PAI-1 gene and having type 2 diabetes mellitus in Tunisian population.展开更多
