Objective To investigate the influence of genistein(Gen) on the growth and apoptosis regulation of hepatoma carcinoma cells SMMC-7721.Methods SMMC-7721 cells were divided into three Gen groups treated with different concentrations(5.0,10.0,20.0 mg?L-1) and control group(without Gen).After SMMC-7721 cells were treated for 24 and 48 h,the changes of ultrastructure of cells were observed under electron microscope, MTT was used to detect the inhibitory rate of proliferation of SMMC-7721 cells,flow cytometry was performed to analyze cell phase;immunohistochemistry was used to detect the expression of Caspases-3 protein.Results Compared with control group,chromatin in cellular nucleus became conglomeration or lumping,with chondriosome swelling in Gen groups.With the increasing of Gen concentration,the cellular nucleus became condensed,heterochromatin agglutinating,ground cytoplasm obviously cavitating;with the increase of Gen concentration and prolongation of time,from 24 to 48 h,MTT showed the inhibitory rate of proliferation of SMMC-7721 cells increased in a time-and dose-dependent manner.Flow cytometry analysis showed that with the increase of Gen concentration,the number of cells at G2/M phase increased,the number of cells at S phase decreased and the ratio of G0/G1 also decreased.Immunohistochemistry results showed the expression of protein Caspases-3 increased with the Gen concentration in a dose-dependent manner(P

Objective To investigate the changes of umbilical adiponectin(APN) levels in newborn whose mothers with gestational impaired glucose tolerance (GIGT).Methods Eighteen neonates of GIGT pregnancies and 50 controls of normal glucose tolerance (NGT) pregnancies were studied.APN concentration was qualified in the umbilical vein serum with radioimmunoassay methods.Capillary blood glucose was measured at the first hour after delivery.Results Umbilical APN level in the GIGT group was significantly higher than that in NGT group [(61.06?16.85)mg/L vs(48.04?15.47)mg/L,t=2.38 P0.05).Conclusions Umbilical serum APN levels are elevated in newborns of GIGT mo-thers.This may be due to the dysregulation of serum APN levels associate with GIGT pregnancy.More attention shall be paid to the metabolic changes of GIGT mothers and their offspring.

Objective To investigate the protective effects of leptin on neonatal seizure in rats by behavioral tests and Bcl2 expression.Methods Twenty Sprague-Dawley (SD) rats were divided into four groups:control group,leptin group,RS group and RS+leptin group on postnatal day 6 (P6),5 rats in each group.From P6 to P12,repeated neonatal seizure model was induced by flurothyl in RS and RS+leptin group rats.From P13 to P22,leptin (2 mg · kg-1 · day-1) was administered by intraperitoneal injection in leptin group and RS+leptin group rats.Forelimb hanging test and open field test were implemented on P30.Bcl2 expression was detected by western blot on P34.Results (1) Neurobehavioral tests:the time of forelimb suspension in RS group((7.10± 1.02) s)was significantly shorter (P＜0.05) than the control group((15.95± 6.11)s) and the time of forelimb suspension in RS+leptin group((13.90±2.64) s)was significant longer (P ＜0.05) than the RS group.In open field test,the number of horizontal movement in RS group (119.80± 28.83) was significantly reduced (P＜0.05) than that in the control group(191.00±37.27) and the number of horizontal movement in RS+leptin group(164.20±26.46) was increased than that in the RS group,but the difference was not significant.The number of modification and stool in RS group was significantly increased (P＜0.05) than that in the control group and the number of modification and stool in RS+leptin group was significantly reduced (P＜0.05) than that in the RS group.(2)Western blot:the expression of Bcl2 in RS group (0.24±0.07),leptin group(0.89±0.09) and RS+leptin group(0.56±0.07) was significantly decreased compared with control group(1.02±0.01) (P＜0.05),and the expression of Bcl2 in RS +leptin group was significantly increased compared with RS group (P＜0.05).Conclusion Leptin improves the brain injury induced by flurothyl on neonatal rats by Bcl2 signaling pathway.

BACKGROUND:Although there is no report of adipose-derived stem cells in ureteral repair, but with the deepening of the research of adipose stem cells, the differentiation conditions of adipose-derived stem cells to the vascular endothelial cells, smooth muscle cells and urothelial cells are more mature, and the experimental research of adipose-derived stem cells in the repair and reconstruction of kidney and bladder is also increasing.
OBJECTIVE:To summarize the adipose-derived stem cells research and its application in damage and repair of urinary system in recent years.
METHODS:The first author retrieved PubMed database and CNKI databases for articles relevant to adipose-derived stem cells in the repair of urinary system published between January 2001 to September 2013 using the keywords of“adipose tissue-derived stem cel/adipose tissue-derived stromal cells/ADSCs;tissue engineering;kidney;ureter;ureathra;bladder;urology”in English and Chinese, respectively. Final y, 52 articles were included for further analysis.
RESULTS AND CONCLUSION:Adipose-derived stem cells which can be found easily and have the unique advantages of multi-directional differentiation ability have been used for repairing and constructing the urinary system. Adipose-derived stem cells provide a new model of treatment for the urinary tract, which solves the traditional problems, including immune rejection, source of organs and ethical issues, and become an ideal cellsource in repair of urinary system. Accumulated data related to adipose-derived stem cells and its experiment and clinical application in repair of urinary system injuries have been reported. But before the cells are widely used in clinic, the fol owing problems need to be solved:its specific surface marker identification, specific conditions and control of celldifferentiation, mechanisms of action.

BACKGROUND:Along with the increasing improvement of bladder tissue engineering research, the vascularization of tissue-engineered bladder after implantation becomes an issue of concern. OBJECTIVE: Combined with relevant literature in recent years, to review the choice, design and application of scaffold materials for bladder tissue engineering as wel as vascularized strategies folowing implantation. METHODS:The first author retrieved PubMed database and CNKI databases for articles relevant to biological scaffold materials in bladder tissue engineering and vascularization of tissue-engineered bladder published between January 2000 to September 2014 using the keywords of “tissue engineering; bladder; biomaterials/scaffolds; vascularization” in English and Chinese, respectively. RESULTS AND CONCLUSION: Recently, the biological scaffolds for bladder tissue engineering include two main categories: natural biomaterials and synthetic polymers. The major target of bladder tissue engineering remains to prepare the best cel-seeded scaffolds, to determine the best source of stem cels, to explore the best differentiation way of stem cels, and to promote angiogenesis and nerve regeneration of implanted scaffolds. Thereinto, promoting vascularization of scaffold materials and building complex tissues is most chalenging. At present, it is stil difficult to precisely control the directional proliferation, migration and differentiation of the attached endometrial cels. Although the vascular network is necessary for the nutrient supply and metabolic waste removal of cels or tissues, strategies to promote angiogenesis or vasculogenesis are stil limited.
