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

Methods A total of 59 women aged 25- 45 were divided into two treatment groups.The subjects in Group A received oral contraceptive A (Oc A: NET 0. 600 mg + EE 0. 035 mg) and B (OcB: LNG 0. 15mg + EEO. 03 mg) alternatively during 12 treatment cycles. Each contraceptive was administrated for three cycles consecutively with starting from OcA. The subjects in the B group received OcB only during 12 treatment cycles. Fasting blood were drawn before treatment, at the end of each trimester treatment and at the end of one cycle after stopping treatment respectively. The concentrations of lipids and apolipoproteins were measured.Results OcA increased the levels of triglyceride(TG) , total cholesterol (TC), high density lipoprotein-cholesterol(HDL-c) , and apolipoprotein AI (apo AI) with statistical significance, whereas OcB significantly decreased all parameters above. As compared with the control group, the overall mean of variation in the study group was much less than that of the control group.Conclusion It indicates that the impacts of oral contraceptives on lipids profile could be moderated by means of alternatively administering Ocs of two different formulations , with estrogen-dominant or progestogen-dominant.展开更多
