Objective To investigate the effect of serum-deprivation on the changes of [ Ca2+ ] i and the protein release of S100A13 and fibroblast growth factor 1 ( FGF-1 ) in thyroid cancer TT cell,and to reveal the role of Ca2+in the protein release of S100Al3 and FGF-1.Methods The protein expressions of FGF-1 and S100A13 in TT cells under serum-deprivation were detected by Western blot.The released FGF-1 protein from TT cells in the supernatant fluid was detected by ELISA.Realtime dynamic examinations on the change of 1 h [ Ca2+ ] i in TT cells under serum-deprivation were detected by confocal laser scanning microscopy.Then,the effect of EGTA( 2.5 mmol/ L),BAPTA-AM (2.5 μmol/L)on distributions of the fluorescence of S100AI 3 and FGF-1 in TT cells under serumdeprivation for6 h were detected by indirect immunofluorescence.Results The expressions of FGF-1 and S100A13 in TT cells after serum-deprivation for4 h and 6 h were reduced( P＜0.05 or P＜0.01 ),but the released FGF-1 protein from TT cells in the supernatant fluid was elevated ( P＜0.05 or P＜0.01).Confocal laser scanning of Ca2+ imaging indicated that [ Ca2+ ] i of serum-deprivation TT cells maintained the relative stabilization within 23 win,but the rapid rise of [ Ca2+ ] i achieved peak value 1.6 μmol/L after 30 min,and remained stable for about 17 win,and thereafter 40 win slowly dropped to a low level From 40 win to 60 win the [ Ca2+ ] i was about 0.3-0.6 μ mol/L.The average [ Ca2+ ] i was higher than that in normal group,EGTA group,and BAPTA-AM group within 1 h.The protein expressions of S100A13 and FGF-1 did not drop obviously in EGTA group and BAPTA-AM group.Conlusion The release of S100A13 and FGF-1 from TT cell under serum-deprivation is possibly related with the change of [ Ca2+ ]i.Both Ca2+-chelating agents EGTA and BA PTA-AM are able to inhibit the rise of [ Ca2+ ] i and release of S100A 13 and FGF-1 from TT cells under serum-deprivation.

A total of 183 patients of ectopic pregnancy due to tubal factors were divided into the methotrexate (MTX),conservative surgery and salpingectomy groups.The dose of gonadotropin,counts of harvested oocytes and high-quality embryos and pregnancy rate were compared among three groups to analyze the differences of in vitro fertilization and embryo transfer (IVF-ET).And the above parameters showed no significant differences (P ＞0.05 ).The clinical pregnancy rate of the conservative group was higher than the other two groups.And the difference was statistically significant compared with salpingectomy ( P ＜ 0.05 ).It suggested that the treatments of ectopic pregnancy had some effects on the outcome of IVF-ET.The pregnancy rate was slightly higher in the conservative surgery group.

BACKGROUND: In the field of intervertebral disc tissue engineering, seed cells primarily consist of nucleus pulposus cells (NPCs) and mesenchymal stem cells (MSCs). NPCs have been known to have several shortcomings: limited source, inconvenient collection, poor proliferative capacity, and difficult in vitro culture.OBJECTIVE: To investigate the proliferation of MSCs after co-culture with NPCs in alginate beads-simulated three-dimensional environment.DESIGN, TIME AND SETTING: A cell observation was performed at the Laboratory of Orthopedics, Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology between December 2007 and October 2008.MATERIALS: Six healthy New Zealand rabbits of 4 months old were provided by the Laboratory Animal Center, Tongji Medical College of Huazhong University of Science and Technology and were used for the present study.METHODS: Rabbit MSCs were isolated and purified using density gradient centrifugation and adherence methods. Rabbit NPCs were isolated and purified using collagenase Ⅱ digestion and adherence methods. Following liposome-mediated green fluorescent protein tranfection and G418 screening, MSCs of passage 3 were cultured either alone (control group) or with NPCs at a ratio of 1:1 (co-culture group) in alginate beads. After 14 days of culture, alginate beads were dissolved and MSCs were collected by flow cytometry sorting.MAIN OUTCOME MEASURES: The expression of collagen Ⅱ and aggrecan in MSCs was detected by RT-PCR and Western blot techniques.RESULTS: mRNA and protein expression of collagen Ⅱ and aggrecan was observed in the co-culture group, but not in the control group, after 14 days of culture.CONCLUSION: MSC differentiation towards nucleus pulposus-like cells can be induced by co-culture with NPCs in a three-dimensional environment.

BACKGROUND: Utilizing tissue engineering technique, various gel systems are served as scaffolds to repair bone defect. The scaffolds should have features of nontoxic and no teratological effects to the body. OBJECTIVE: To observe the effect of sodium alginate-gelatin/osteoblast gel on chromosomal pattern aberration in rabbits. DESIGN, TIME AND SETTING: The in vivo material animal experiments were conducted at the Beijing Shijitan Hospital and Department of Histology and Embryology, Peking University Health Science Center from October 2007 to March 2008. MATERIALS: A total of 12 New Zealand rabbits, aged 2 months, with clean grade, were randomly divided into 2 groups. The experimental group contains 4 female and 4 male rabbits, and the remaining 4 females were served as the control group. Sodium alginate dried powder were purchased from Sigma, USA, and the gelatin dried powder were supplied by Liidao Company, Hebei, China. METHODS: Following numbering, bone marrow was collected from 12 rabbits. Bone marrow stromal stem cells (BMSCs) were isolated by the density gradient centrifugation, and then in vitro cultured with osteoblast inductor. Osteoblasts following passage were an order of magnitude of 10~7. Bright pink gelatiniform liquid with mass ratio of sodium alginate and gelatin at ratio of 2:3 was prepared. Rabbit osteoblasts with final concentration of 5×10~9/L were mixed with CaCb solution to form fruit jelly-shaped sodium alginate-gelatin/osteoblast gel. Critical-sized calvarial defects were created in diameter of 1.5 cm in 12 rabbits. After 1 week, cell/scaffold complex (0.5 mL) was implanted to repair the bone defect in the experimental group. There was no treatment in the control group. MAIN OUTCOME MEASURES: The change of chromosomal pattern was observed at 3 months following reparation. RESULTS: No Chromosome somatotype aberration was found in 100 metaphases in the experimental group. From 400 metaphases of the control group, 4 abnormal cells were found, with 1% chromatid-type aberration ratio. Meantime, 12 abnormal cells in 800 metaphases of the control group were found, with 1.5% chromatid-type aberration ratio. The numerical value was within the normal range. Chromosome karyotype analysis: the chromosome number of each experimental rabbit was 2n=44, karyotype of the control rabbit was 44, XX, which was normal female; or 44, XY, normal male, no abnormal was found. The female rabbit in the experiment group was 44, XX, no abnormal was seen. CONCLUSION: From the cytogenetoxicity point of view, sodium alginate-gelatin/osteoblast gel is safe in repairing bone defects.

Objective:This study was conducted to evaluate whether or not immediate breast reconstruction influences quality of life and patient body image satisfaction outcomes among Chinese women with breast cancer compared with modified radical mastecto-my. Methods:Sixty patients with breast cancer and were operated from July 2011 to July 2012 in Cancer Institute&Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were included. These patients were divided into two groups:Ⅰ(30 patients) underwent modified radical mastectomy andⅡ(30 patients) underwent mastectomy with immediate breast reconstruction. Pa-tient satisfaction with breast reconstruction was evaluated by functionally assessing cancer therapy-breast cancer scale (FACT-B) and the scales that we designed. Results:No significant differences were observed between the two groups in terms of baseline characteris-tics, histopathological characteristics, and incision conditions (P>0.05). The patients in groupⅡ(immediate breast reconstruction) ex-hibited improved body image satisfaction outcomes (41.1 ± 10.8 vs. 33.2 ± 8.8, P=0.003);this difference was still observed after adjust-ment for confounding factors was performed by multiple linear regression. No significant difference was found between the two groups in terms of total FACT-B score and psychological evaluation score (P>0.05). Conclusion:Chinese women who prefer immediate breast reconstruction exhibited an improved body image satisfaction.
