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.

The morbidity of obesity-related glomerulopathy(ORG) is on the increase in recent years.Studies have demonstrated that the chronic inflammation may play a key role in the pathogenesis of obesity related metabolic dysfunction.LipoxinA4 (LXA4) is an important anti-inflammatory lipid mediator,which is well known as the stop signal of the inflammatory reaction that can promote the resolution of inflammation.This review will provide a survey of recent advances on ORG and LXA4.

Objective To observe the therapeutic effect of Gusongbao capsule for osteoporosis. Methods Experimental osteoporosis rat models were established by extirpation of bilateral ovaries of female rats. Bone morphological indexes, blood biochemical indexes, and daily output of calcium and phosphorus in urine in the Gusongbao treatment group and control group were determined. Results Compared with the control, the average width of bone trabecula, relative bone volume, average thickness of bone cortex, bone calcium, and the average gray degree of femoral head and femoral shaft were high, and the serum calcitonin (CT) and blood calcium increased markedly in the treatment group. High-dose and moderate-dose Gusongbao increased number of osteocytes in per unit area of bone trabecula, decreased serum alkaline phosphatase (ALP) level and reduced the daily output of urine calcium. Conclusion Gusongbao capsule can obviously inhibit the excessive bone transformation and promote the re-construction of bone and exerts an antagonistic effect on osteoporosis in ovariectomized rats.

Objective To observe the anti-osteoporosis effect of Gusongbao capsule (GC).Methods Osteoporosis rat models were induced by gastric infusion of vitamin A acid at a dose of 70 mg/kg for 14 days. The bone morphological and blood biochemical indexes and the amount of calcium and phosphorus in urine excreted every day were determined in both treatment group (treated with Gusongbao) and model control group.Results In the treatment group,the average width of bone trabecula,relative bone volume,average thickness of bone cortex,bone calcium,cell number in per unit area of bone trabecula,and the average gray degree of caput femoris and femoral shaft were higher than those in the moderate group. High dose (0.8 g/kg) and middle dose (0.4 g/kg) of GC increased bone phosphorus level and decreased urine calcium level markedly and high dose of GC also increased serum level of CT (P

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.

As the research work went further and more detailed, a variety of new treatments compete to come out.However, it remains unclear that how the antigen works to distinguish cancer cells and normal cells.Neoantigen, which is located in the tumor cell surface of a specific antigen, its presence makes human immunotherapy into new areas which may make personalized treatment possible in the near future.Emerging data suggest that the identification of such newantigens is a major factor in clinical immunotherapy.They can form a biomarker in cancer immunotherapy to provide targets for a variety of therapeutic approaches to attack, which allows T cells to selectively enhance the immune response against this class of antigens.

Objective To investigate the relationship between adhesion molecule CD44v6,intercellular adhesion molecule-1 (ICAM-1) and lymph node metastasis in early stage of cervical squamous cell carcinoma.Methods Seventy-four specimens of cervical cancer stage Ⅰ b1,20 specimens of normal cervical tissue and 20 specimens of cervical squamous cell in situ carcinoma were collected from Jiangxi Provincial Maternal and Child Health Care Hospital.The expression of CD44v6 and ICAM-1 in cervical tissue was detected by real-time PCR and immunohistochemistry.The lymphatic vessel density (LVD) labeled by D2-40 was detected by immunohistochemistry.The relationship of CD44v6,ICAM-1 and LVD with the differentiation degree and lymph mode metastasis was investigated.Results The positive expression rate of CD44v6 and ICAM-1 in normal cervix,cervical squamous cell carcinoma in situ,and cervical carcinoma tissues was gradually increased,which were 0,75.00％,87.84％ and 10.00％,45.00％,81.08％ respectively.Their mRNA expression amount was gradually increased,which were 0,0.24±0.02,1.02±0.11 and 0.10 ± 0.00,0.19±0.02,1.03 ± 0.10 respectively,the differences were statistically significant (P＜0.01).LVD was gradually increased in normal cervix,cervical squamous cell carcinoma in situ,and cervical carcinoma (P＜0.01).The expression of CD44v6,ICAM-1 and LVD in low differentiated cervical carcinoma tissue was higher than that in high and middle differentiated cervical carcinoma (P＜0.01).The expression of CD44v6,ICAM-1and LVD in lymph node metastasis was higher than that in non-lymph node metastasis (P＜0.01).The expression of CD44v6,ICAM-1 and LVD in cervical cancer tissue had each two positive correlation (P＜0.01).Conclusion CD44v6 plays a promoting role in the progression of cervical cancer,which with ICAM-1 and LVD synergically promote the cervical cancer development,and could be used as an effective indicator for judging lymph node metastasis and diagnosis of cervical cancer.

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.
