ABSTRACT
Objective To observe the effects of hirudo capsules on degree of platelet activation and blood rheology in patients with cerebral arteriosclerosis. Methods 122 patients with cerebral arteriosclerosis were randomly divided into two groups by the random number table:observation group(61 cases)and control group (61 cases). The two groups received conventional treatment such as antihypertensive and hypoglycemic drugs,and 100 mg of aspirin once a day. In the observation group,additionally hirudo capsules 0.75 g,3 times a day were given. The therapeutic course in both groups was 2 months. Prior to the start of treatment and on the next day after the end of treatment,traditional Chinese medicine(TCM)clinical syndrome integral,platelet membrane glycoproteins caspase 1 (PAC-1),platelet adhesion molecule P selection(CD62P)positive rate,and blood rheology indexes were detected,in addition to the adverse reactions . Results Before treatment,there were no statistical significant differences between the two groups in terms of TCM clinical syndrome integral such as headache,dizziness,head fullness,multiple somnolence amnesia,lip dark purple,sublingual veins purple in color,PAC-1,CD62P positive rate,hemorheology indexes(all P>0.05). After treatment,TCM clinical syndrome integral PAC-1,CD62P,low shear viscosity,high shear viscosity,plasma viscosity and the hematocrit of two groups were significantly lower than those before treatment, the improvement in observation group being more remarkable〔headache:0.75±0.69 vs. 1.23±0.92,dizziness:0.96±0.78 vs. 1.54±1.24,head fullness:0.65±0.59 vs. 1.48±1.17,multiple somnolence amnesia:0.77±0.72 vs. 1.69±1.14,lip dark purple:0.83±0.81 vs. 1.32±0.79,sublingual veins purple:0.84±0.67 vs. 1.20±0.74, PAC-1:(10.31±4.57)%vs.(15.13±6.27)%,CD62P:(11.39±5.24)%vs.(16.40±7.91)%,low shear viscosity (mPa?s):7.52±3.37 vs. 8.97±3.50,high shear viscosity(mPa?s):4.35±1.12 vs. 5.58±1.19,plasma viscosity (mPa?s):1.54±0.35 vs. 1.88±0.42,hematocrit(HCT):0.43±0.09 vs. 0.49±0.10〕. In the patients' follow-up, there were no obvious side effects of hirudo capsules. Conclusion Hirudo capsule is a safe and effective drug for treatment of patients with cerebral arteriosclerosis as it is helpful in reducing platelet activation degree and improving the blood rheology indexes.
ABSTRACT
Objective To investigate the association between thromboxane A2 receptor(TXA2R)gene C795T, T924C,G1686A,rs2271875,rs768963 polymorphisms and aspirin resistance(AR)in Chinese Han population. Methods 168 in-patients with cerebral infarction who had been given aspirin from Zhejiang Provincial Taizhou Central Hospital from October 2009 to May 2013 were enrolled. The platelet aggregation rate was conducted by optical method. The inspections of triglyceride(TG),total cholesterol(TC),high density lipoprotein cholesterol(HDL-C) and low density lipoprotein cholesterol(LDL-C)were conducted by enzymatic colorimetry,whereas blood glucose was tested by hexokinase method. The genotypes of three exons loci C795T,T924C,G1686A and two promoters loci rs2271875,rs768963 polymorphisms in TXA2R gene were detected by the polymerase chain reaction-ligase detection reaction(PCR-LDR)technique. The patients were divided into aspirin sensitive group(AS group,139 cases) and AR group(39 cases)according to the aspirin sensitive degree. The differences between two groups in age, smoking,serum TG,TC,HDL-C,LDL-C,concentration of blood glucose and blood pressure(systolic pressure, diastolic pressure)were compared,and in the mean time,the differences between two groups of TXA2R C795T, T924C,G1686A,rs2271875,rs768963 genotype distribution were also compared. Results AR group had higher incidences of cigarette smoking〔89.7%(35/39)vs. 69.8%(90/129)〕and high blood sugar(mmol/L:8.086±2.785 vs 5.631±1.662,P0.05). It was shown that there was no correlation between TXA2R gene polymorphism and AR. Conclusion The patients with smoking,high concentration of blood glucose have a higher incidence of AR,no correlation between TXA2R gene polymorphism and AR is found.
