Objective To investigate the correlation between ACE gene polymorphisms and stroke of Han nationality people in Fangshan district of Beijing. Methods The Insertion/Deletion(ID) polymorphisms of ACE gene were detected in 63 patients with cerebral hemorrhage,and 713 patients with cerebral infarction and 235 health control by polymerase chain reaction(PCR). We observed the frequencies of genotype of deletion homozygote(DD),insertion homozygote(II) and insertion/deletion heterozygote (ID) and the alleles of D and I. Also we analyzed the association among I/D polymorphisms of ACE gene with serum glucose(GLU),triglyceride(TG),cholesterol(TC) levels. Results There was no significant difference in the frequencies of both genotypes of DD,ID,II and alleles of D and I in three groups. The serum GLU levels in patients carrying ID,II genotype were higher than those in healthy control(P

Objective To investigate the physiological characteristics and the association with low prevalence of hypertension in "desert people" ,as an isolated population,in Taklimakan Desert.Methods All data were obtained from each person by questionnaire and standardized physical examinations. Total 469 subjects received examinations,including 359 subjects of "desert people" (M/F=205/154),aged from 15~99 years; 101 subjects of Uyghur from Yutian county (M/F=51/50),aged from 20~85 years,as controls. Some parameters :TC,TG,LDL-C,HDL-C,Apo-A,Apo-B,Lp-a,BUN,UA and CRE were determined. The statistical analysis was performed with SAS9.1.3 Version (Inititute Inc. Cary,NC. USA). Continuos values were expressed as mean?SD.Differences between groups were examined by student's t test,and statistical difference was considered when the P value was less than 0.05.Results 1)The height in "desert people" was significantly taller than that in controls.P value was 0.0317 for male and P60 years,P value was 0.0127 and 0.0443,respectively.(3)The prevalence of hypertension in "desert people" was 7%(24/359),that was significantly lower than that in controls(30.7%,31/101),P
