Methods Altogether 139 male CHD patients (CHD group) aged 60-92 years and 400 healthy men (control group) aged 60-90 years were included in this cross sectional study. The plasma concentrations of dehydroepiandrosterone sulfate (DHEAS),total testosterone (TT),free testosterone (FT),estradiol (E2),sex hormone binding globulin (SHBG),luteinizing hormone (LH),and follicle-stimulating hormone (FSH) were measured. The androgen receptor (AR) was tested by flow cytometry. Correlations between CHD and levels of sex hormones and AR were analyzed. Results Compared with the control group,the levels of DHEAS,TT,FT,SHBG,and the fluorescence intensity of AR in the CHD group significantly reduced (P<0.05),while the levels of FSH and E2 significantly increased (P<0.01). Age was negatively correlated with TT (r=-0.28,P=0.00) and FT (r=-0.17,P=0.01),while it was positively correlated with SHBG (r=0.14,P=0.04) and E2 (r=0.33,P=0.00). AR fluorescence intensity was negatively correlated with systolic blood pressure (r=-0.12,P=0.01). Binary logistic regression analysis showed that TT,SHBG,and AR were all negatively correlated with CHD (P<0.05). Conclusions Elderly male patients with CHD are found to have low levels of DHEAS,TT,FT,SHBG,and AR,while high concentrations of E2 and FSH. Low levels of TT and SHBG may be the potential risk factors of CHD in elderly men.展开更多

The results indicated that In the SCC tissue of the oral mucosa there were 5 cases of ER+ and PR- and 32 cases of both ER+ and PR+. Thirty-seven cases, the summation of the above two items, were considered as receptor(+),therefore the rate of the receptor(+) being 82.22%. ER+ and PR+ were cd related to the sex and age of patients, the neck lymph nodes' metastasizing or not and affected parts of the tumor, while they were related to the differentiation degree of the tumor. The rate of receptor(+) decreased with the decrease of the differentiation degree of the tumor. By X2 test a remarkable difference between grade Ⅰand grade Ⅲ of SCC of the oral mucosa was shown. It is suggested that SCC of the oral mucosa may probobly be hormone dependent tumor. The authors consider that the SCC detection for ER and PR could not only be one of the indices of biologic characteristics for that tumor but also as bases of anti-hormone treatment.展开更多
