Objective To investigate the effect of combined antiplatelet drugs on clinic and aggregation activity of platelet in patient with aucte myocardial infarction(AMI).Methods Consecutive 97 cases with AMI were redomized to receive clopidogrel plus aspirin(treated group,n=48) or aspirin alone(placebo group,n=49) for 30 days.Before and after treatment,the clinical recurrent angina,improvement of heart function,death,ST segment changes of electrocardiogram and the rate of maximun aggregation of paltelet were tested and analysed.Results Recurrent angina occurred in 10.0%(5 cases) in the treated group and 20%(10 cases) in the placebo group.The total frequency of improvement of heart function occurred in 36.7%(18 cases) in the treated group and 22.4%(11 cases) in the placebo group(?~2=3.638,P=0.045).Death occurred in 4%(2 cases) in the treated group and 8%(4 cases) in the placebo group.ST segment of electrocardiogram decreased from (0.36?0.13)mV to (0.13?0.08)mV,compared with placebo from (0.35?0.14)mV to (0.16?0.90)mV(t=3.012,P=0.04).The rate of maximum aggregation of platelet induced by ADP reduced from (74.54?8.99)% to (34.09?9.23)%,the placebo from (72.30?7.78)% to (56.54?6.92)%(t=13.42,P

OBJECTIVE:To investigate the influence of hypoglycemic combined with lipid-lowering statin therapy on lipid profile of mixed dyslipidemia patients with T2DM and TG in 2.3-4.5 mmol/L. METHODS:In total of 80 patients with T2DM and mixed dyslip-idemia of TG in 2.3-4.5 mmol/L in our hospital was determined according to the patient’s age,chronic complications of diabetes and life expectancy. Hypoglycemic(insulin joint oral hypoglycemic drugs,or oral antidiabetic drug alone)treatment was given according to corresponding target,meanwhile statin lipid-lowering therapy was also given. HbA1c,TG,TC,HDL-C and LDL-C were determined and BMI was calculated before treatment. Alipid was reviewed after two weeks,then the difference was compared. RESULTS:Com-pared with before treatment,TG,TC and LDL-C were decreased by 50.28%,42.91% and 44.37% after hypoglycemic combined with lipid-lowering statin therapy,with significant difference(P<0.01). Insulin was the better choice to reduce the level of TG,there was significant difference between insulin treatment and oral hypoglycemic drugs alone (P<0.05). CONCLUSIONS:For T2DM patients with mixed dyslipidemia of TG between 2.3-4.5 mmol/L,hypoglycemic combined with lipid-lowering statin therapy can not only signifi-cantly reduce the levels of TG,TC,LDL-C and TG to 2.3 mmol/L or less,and even normal. Compared with oral hypoglycemic drugs alone,the compliance rate of TG was higher in the combination of insulin and oral hypoglycemic drugs.

Objective: To explore the safety and efficacy of intravenous thrombolysis therapy with tissue plasminogen activator ( tPA) in aged acute ischemic stroke patients. Methods:The patients treated with intravenous tPA were analyzed and divided into≥80-year group (n=16) and <80-year group (n=79), and 30 hospitalized patients with the age above 80 years without thrombolytic therapy were selected as the control group. The prognosis of the three groups was compared. Results:①The incidence of ICH in the two thrombolysis therapy groups was 13. 9% and 18. 7% in 24h, and that of SICH was 5. 1% and 6. 3% with no significant difference (P>0. 05). ② No significant difference was found in favorable prognosis between the two therapy groups 90 days after thrombolysis (P=0. 771), while very bad prognosis rate was higher in the≥80-year group than in the <80-year group (P<0. 05). ③The≥80 years group had an increased favorable outcome compared with the control group (P<0. 05), while the very bad prognosis rate in the two groups showed no significant difference (P>0. 05). Conclusion:It is safe and effective for old patients to receive IV-tPA throm-bolysis therapy.
