ABSTRACT
Objective To explore the correlation between catechol-O-methyltransferase (COMT) gene polymorphism and the occurrence of senile hypertension with depression.Methods Ninety-eight Han inpatients with senile hypertension complicating depression(elderly hypertension complicating depression group) in our hospitals from January 2010 to July 2014 were selected and contemporaneous 100 Han cases of senile hypertension(elderly hypertension group) and 100 healthy Han elderly people(elderly control group) served as the study subjects.PCR-RFLP was employed to detect COMT gene 1947 locus polymorphism distribution frequency for conducting analysis.Results The genotype frequencies of AA and AG at COMT 1947 locus in the elderly hypertension complicating depression group were significantly higher than those in the elderly control group(28.57 ％,51.02 ％ vs.19.00 ％,39.00％,P＜0.01).The A allele frequency in the elderly hypertensive complicating depression group was significantly higher than that in the elderly control group(54.08％ vs.38.50％,P＜0.01).The risk of hypertension complicating depression occurrence in the population carrying A allele was 1.881 times that of carrying G allele(OR =1.881,95 ％ CI:1.261-2.807,P＜0.01).The various genotypes frequencies had no statistical difference between the elderly hypertension group and elderly hypertension complicating depression group(P＞0.05).However,the COMT 1947A/G allele frequencies had statistical difference between the two groups (P＜0.05).The A allele frequencies in the hypertension complicating depression group was 54.08％,which was higher than 42.50％ in the elderly hypertension group (P＜0.01),moreover the risk of depression occurrence in the population carrying A allele was 1.593 times that of carrying G allele(OR=1.593,95％CI:1.071-2.37,P＜0.01).Conclusion COMT gene polymorphism could have correlation with the occurrence of elderly hypertensive complicating depression.Detecting COMT 1947 locus genotype in elderly patients with hypertension can serve as an important indicator for predicting depression occurrence.

ABSTRACT
Objective To investigate the effect of probiotics on the blood lipid metabolism of elderly patients with coronary artery disease (CHD).Methods The clinical data of 100 elderly CHD patients who were admitted in our hospital from May 2012 ～November 2015 were collected.The enrolled patients were randomly divided into observation group and control group,50 cases in each group.All patients were routinely given medication for secondary prevention of CHD,patients in the observation group were additionally given oral probiotics.Then we observed the changes in the lipid levels of patients before and after 12 weeks treatment.Results The serum total cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterol (LDL-C) of patients in the observation group were improved more significantly than the control group,the difference was significant (P＜0.05).The serum total High-density lipoprotein cholesterol (HDL-C) was improved more significantly than the control group.Conclusion Probiotics adjuvant therapy can significantly improve the blood lipid indexes in elderly CHD patients.
ABSTRACT
Objective To investigate the correlation between angiotensinogen gene M235T polymorphism and gerontism hypertension combined with depression. Methods The polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) technique were used to detect the M235T genetic polymorphism in 117 patients with hypertension and 91 patients with hypertension and depression, and 101 healthy subjects without clinical evidence of hypertension and depression.Result The frequency of TT genetype and T allele was higher in group with hypertension and the group with hypertension and depression than that in the control group ( <0.05) . Conclusion Angiotensinogen gene M235T polymorphism is significantly correlated with the gerontism hypertension combined with depression.
