ABSTRACT
Objective To assess the clustering of cardiovascular risk factors and their effects on target organ damage in elderly patients with hypertension .Methods 421 treated elderly hypertension patients were divided into 5 groups based on the number of risk factors :hypertension without additional risk factor (group A ,25 cases) ,and the other 4 groups were complicated with 1 (group B ,76 cases) ,2(group C ,127 cases) ,3(group D ,128 cases)and ≥ 4 (group E ,65 cases) risk factors .The structure and function of heart and carotid artery were examined by ultrasonography in order to evaluate the damage of target organ and the morbidity .Re-sults The patient groups with three or more risk factors showed significantly higher levels of BMI ,plasma glucose ,triglyceride , LDL-C cholesterol ,serum creatinine and serum uric acid ,and needed greater number of antihypertensive drugs ,compared with other groups(P<0 .05) .The patient groups with two or more risk factors showed significantly higher levels of LVMI ,IMT and MAU/Cr compared with group A(P<0 .05) ,and significantly lower levels of the creatinine clearance (P<0 .05) .In addition ,they showed significantly higher incidences of coronary heart disease and cerebrovascular disease and chronic kidney disease compared with group A (P<0 .05) .Conclusion These results suggest that the hypertensive patients with clustering risk factors required greater number of antihypertensive drugs .The more additional risk factors exit ,the more target organ damages and higher morbidity occur ,and more intensive intervension are required to control not only blood pressure but also other complicated risk factors .
ABSTRACT
Objective To analyse the correlation of apolipoprotein E genotype and Alzheimer's disease(AD) in old population in Urumqi.Methods The polymerase chain reaction and restriction fragment length polymorphism(PCR-RFLP) techniques were used to detect the distribution of genotype, gene frequency of ApoE alleles in 60 cases with sporadic AD and 90 normals as control.Results The frequency of ApoE?2, ApoE?3, ApoE?4 was 6.67%, 75.83% and 17.50% respectively in AD group, while in control group, it was 13.33%, 79.45% and 7.22% respectively. The frequency of ApoE?4 allele in AD group was higher than that in control group( P
ABSTRACT
Gene analysis of the first family with ?-thalassemia in Xinjiang was carried out by polymerase chain reaction (PCR) in combination with dot blot hybridization of allele -specific oligonucleotide (ASO) probes. Seven of the 12 family members were heterozygous for the IVS- Ⅱ-654 (C→T) mutation. The abnormal ? gene of proband was confirmed from the paternal side according to family survey, clinical syndrome and hematological data.
