Objective:To study the cognitive characteristics of older women about the ethical issues and stipula-tion of test-tube baby technology. Methods:A survey was undertaken with 203 female patients, who were ran-domly selected from three hospitals in Xi′an accepted test-tube baby technology. The basic characteristics and ethical cognition regarding embryos, offspring, and informed consent were included in the questionnaire. Results:Female over 40 had a statistical significant higher score on the cognition of offspring (12. 48 ± 3. 08) and informed consent (13. 27 ± 2. 31) related ethical issues comparing to other age group (P<0. 05). Age, educational status, monthly income were statistically positive related to the scores of the Ethical Cognitive Scale ( P<0 . 05 ) . Conclu-sion:Older women paid more attention to medical risks and policy rules to test-tube baby. And they had a strong aspiration to obtain a child through surrogacy. For older women with low education, low-income, the ethical cog-nition was not ideal, hospitals should pay attention to the use of modern multimedia to help patients better under-stand related ethical issues in test-tube baby.

Objective:To investigate the criterion-related validity of Menopause-Specific Quality of Life Questionnaire (MENQOL)-Chinese version and to evaluate the effect of menopausal symptoms on health related quality of life. Methods:This study was a cross-sectional survey. Three communities were randomly chosenin Changsha,and then 340 menopausal women aged 45-55 years were randomly chosen from the documented data of the 3 community health service centers. They were required to fill out 4 questionnaires: demographic questionnaire, MENQOL-Chinese version, Kupperman Index (KI) and World Health Organization Quality of Life (WHQOL)-BREF. Correlation analysis was used to measure the criterion-related validity. Results: MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) and KI total score were positively correlated (r=0.800,0.751, 0.607, 0.906 respectively); while negatively correlated with WHOQOL-BREF total score (r =-0.694,-0.851,-0.585,-0.873 respectively); MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) were signiifcantly correlated with WHOQOL-BREF subscales (physical, psychological, social relationship, environment), and the physical domain was the highest among the correlation coeffcients (r=-0.915). Conclusion:MENQOL-Chinese version shows relatively high criterion-related validity compared with KI and WHOQOL-BREF, which can be widely used to measure the quality of life of menopause women in China.

Objective To observe the expressions of thyroid-stimulating hormone receptor (TSHR) protein and mRNA in thyroid gland of lactating rats.Methods Eighty adult Wistar rats (60 females and 20 males),weighting 210-250 g were selected.The 60 female Wistar rats were divided into 6 groups according to their body weight by means of random number table:normal non-pregnant group,lactating for 5,10,15 and 20 days groups and weaning for 5 days group,10 rats in each group.All rats were fed with conventional fodder and tap water freely,and the rats of lactating groups except the normal non-pregnant group cohabited with male rats (3 ∶ 1).Then all rats were killed on the 5th,10th,15th and 20th day after lactation and on the 5th day after weaning to get thyroid tissues.The expressions of TSHR protein and mRNA were determined by immunohistochemical staining and realtime quantitative PCR.Results TSHR protein was expressed in cytoplasm and membrane of rat thyroid follicular cells.The expression of TSHR protein in thyroid gland was significant different statistically between groups (x2 =11.227,P ＜ 0.05); the staining intensity of rat thyroid tissues in the normal non-pregnant gruop (weak,n =2; moderate,n =5; strong,n =3) was stronger than that of rats lactating for 5 days (weak,n =7; moderate,n =3; x2 =5.895,P ＜ 0.05).But the expression of TSHR protein in thyroid tissues in the normal non-pregnant group was not significantly different statistically compared with the expression of TSHR protein in other groups (lactating for 10,15and 20 days) and weaning for 5 days group (all P ＞ 0.05).The expression of TSHR mRNA in thyroid gland was significantly different statistically between groups (F =2.970,P ＜ 0.05); the expression of TSHR mRNA in lactating for 5 days group (0.74 ± 0.13) was lower than that of the non-pregnant group (1.02 ± 0.24,P ＜ 0.05); and the expression of TSHR mRNA in the normal non-pregnant group was not significantly different statistically compared with those of other groups (lactating for 10,15 and 20 days) and weaning for 5 days group (all P ＞ 0.05).Conclusion TSHR is widely expressed in thyroid gland of lactating rats,but relatively lower in early lactation period.

Objective To study the effect of BRMS1 on the invasion and metastasis of ovarian cancer cells. Methods BRMS1 small interfering RNA (BRMS1-siRNA) was transfected into human ovarian cancer cell-line OVCAR3 by liposome transfection method. The cells were divided into 3 groups: experimental group with BRMSl-siRNA, negative control group with siRNA that did not impact any gene, blank control group without any transfection. Changes of invasion and migration in the cells were per-formed using transwell invasion and migration assay. Results BRMS1 gene was silenced in OVCAR3 cell line successfully detecting by quantitative real-time RT-PCR and immunoblotting.In transwell invasion assay,the numbers of cells in lower chamber passing through the membrane in transfected group were more than negative control group and blank control group (190±8.5, 144±7.8 and 146±6.8 respectively) (t=8.747, t=8.869, P=0.000), while in transwell migration assay, the numbers of cells in lower chamber passing through the membrane in transfected group were more than negative control group and blank control group were (231 ±8.9, 177±9.7 and 182±7.9 respectively) (t=9.314, t=9.224, P=0.000), both with significant differences among the 3 groups. Conclusion BRMS1 gene could suppress the invasion and metastasis of ovarian cancer cells.
