ABSTRACT
Objective:To explore the relationship between angiotensin converting enzyme (ACE) gene insertion/dele‐tion (I/D) polymorphism and familial essential hypertension (EH) .Methods :Fluorescent in situ hybridization stai‐ning DNA sequencing test was used to detect ACE gene I/D genotype frequency and allele frequency in 46 familial EH patients (familial EH group) ,64 EH patients without family history (non‐familial EH group) and 43 healthy people (healthy control group) .Results:In healthy control group ,non -familial EH group ,familial EH group ACE gene DD genotype frequency was 11.6% ,32.3% and 37.0% ;distribution frequency of D allele was 33.7% , 52.3% and 57.6% respectively .Compared with healthy control group ,there were significant rise in ACE gene DD genotype and D allele frequency in familial EH group and non -familial EH group (P0.05) .Conclusion:ACE gene DD genotype and D allele may be genetic predisposing genes of patients with essential hypertension ,and there is no significant difference in genetic constituent ratio between familial EH patients and non‐familial EH patients .
ABSTRACT
Alterations of serum vitamin D metabolites were observed by competitive protein-binding assay and radioreceptor assay in 46 patients with renal disease inckding chronic renal failure (CRF), nephrotic syndrcme (NS) and nephritis. The results indicated that serum 25-hydroxy-vitamin D (25-OHD) level decreased 41.2% as compared with the control group (P
