RESUMO
Objective To analyze the related factors of carotid atherosclerosis in type 2 diabetes mellitus pa-tients complicated with nonalcoholic fatty liver disease .Methods 288 type 2 diabetes mellitus patients complicated with nonalcoholic fatty liver disease were divided into carotid atherosclerosis group (group A) and non-carotid athero-sclerosis group ( group B ) , according to whether they had carotid atherosclerosis .The related factors of these two groups,such as BMI,blood pressure,blood glucose,blood lipid,liver function were analyzed.Results The two groups had no significant differences in systolic pressure and diastolic pressure (P>0.05).ALT,BMI,HbA1c,FPG,TG,TC, AST of group A were significantly higher than group B [ALT (55.12 ±9.13)mmol/L vs (36.22 ±8.76)mmol/L, BMI (28.48 ±4.69)kg/m2 vs (23.96 ±3.73)kg/m2,HbA1c (8.57 ±1.69)mmol/L vs (7.62 ±1.28)mmol/L, FPG (9.36 ±2.24)mmol/L vs (8.67 ±1.98)mmol/L,TG (2.12 ±0.38)mmol/L vs (1.23 ±0.17)mmol/L,TC (5.56 ±1.25)mmol/L vs (4.31 ±1.09)mmol/L,AST (25.34 ±5.23)mmol/L vs (21.19 ±4.71)mmol/L](t=17.564,8.726,5.163,2.694,8.788,6.894,all P<0.01).The multiple stepwise regression analysis showed that there was a positive correlation between ALT and BMI (r=0.132,P<0.01),a negative correlation between ALT and AST(r=-0.091,P<0.01).Conclusion The level of ALT could be used as a risk index to judge whether the type 2 diabetes mellitus patients complicated with nonalcoholic fatty liver disease had carotid atherosclerosis .
RESUMO
To explore the correlation between the C807T polymorphism of platelet membrane gly- coprotein Ⅰa (GPⅠa) gene and aspirin resistance in Chinese people, 200 patients with high-risk of atherosclerosis took aspirin (100 mg/d) for 7 days. Platelet aggregation function was detected using adenosine diphosphate (ADP) and arachidonic acid (AA) before and after the administration of aspi- fin. Then the subjects were divided into three groups according to the results of platelet aggregation function: an aspirin resistant (AR) group, an aspirin semi-responder (ASR) group and an aspi- fin-sensitive (AS) group. Platelet GPⅠa gene 807CT polymorphism was examined by means of po- lymerase chain reaction-sequence specific primers (PCR-SSP). The results showed that T allelic fre- quency in AR group and ASR group were higher that of AS group (P<0.005), and the prevalence of genotypes (TT+TC) of these two groups was significantly higher than that in AS group (P<0.05). Platelet GPⅠa T allele was significantly associated with aspirin resistance as revealed by multiple logistic regression (OR=3.76, 95% CI: 2.87-9.58). The results suggest that inherited platelet GPⅠa variations may have an important impact on aspirin resistance and the presence of GPⅠa T allele may be a marker of genetic susceptibility to aspirin resistance.
