Objective To research on the proliferation and differentiation in vitro of primordial germ cells. Methods We got plenty of primordial germ cells(PGCs) by co-culture of PGCs with sertoli cells(SCs).The primary cells formed embryoid bodies(EBs) by suspension culture.furthermore,these EBs were plated on gelatin-coated culture plates for spontaneous differentiation. Results We got plenty of PGCs by coculture.Primary PGCs and passaged PGCs for histochemistry staining with AKP and immunohistochemistry staining for SSEA-1 display positive character.The EBs by suspension culture differentiated into epithelial-like,fibroblast-like and neuronal-like cells in vitro. Conclusion Primordial germ cells can proliferate and keep the character of stem cells by co-culture with SCs.PGCs can form EBs by suspension culture,most of these EBs can differentiate into neuronal-like cells,they also can differentiate into epithelial-like and fibroblast-like cells in vitro.

The prevalence of prediabetes is increasing rapidly in China, and with higher prevalence in coronary heart disease and hypertension patients. Diabetes can be controlled and prevented, previous studies have confirmed that lifestyle interventions and drug interventions can delay the progression of prediabetes to diabetes, and acarbose can be used for the primary prevention of cardiovascular events in impaired glucose tolerance(IGT) and diabetic patients, but benefits of drug intervention for secondary prevention of cardiovascular disease in IGT population are uncertain. The Acarbose Cardiovascular Evaluation(ACE) Study is a multicentre, randomized, placebo-controlled, double-blind study, with the aim of assessing the use of acarbose to reduce the risk of cardiovascular events and the onset of diabetes in IGT patients with cardiovascular disease in China , the results will be very meaningful and valuable for the prevention and treatment of diabetes. We will predict the results of ACE Study based on previous evidences.

Objective The objective of this study was to determine the effect of curative chemotherapy regimen on breast cancer cells and its mechanism.Methods A tumor-bearing mouse model was established and routine dose of capecitabine was given as a conventional chemotherapy group.Continuous low-dose capecitabine chemotherapy was used as a radiotherapy group and no chemotherapy was used as a control group.The expression of microvessel density(MVD),vascular endothelial growth factor(VEGF)and thrombospondin 1(TSP-1)were measured by flow cytometry.The percentage of myeloid-derived suppressor cells(MDSCs),NK cells and macrophages in the program was observed.The tumor size and blood leukocyte count were measured after chemotherapy.Results MVD and VEGF in the radiotherapy group were significantly decreased and TSP-1 was significantly increased in comparison with the conventional chemotherapy group(P<0.05).The proportion of MDSCs in the radiotherapy group was significantly decreased,the proportion of NK cells and macrophages were significantly increased when compared to the conventional chemotherapy group(P<0.05).The tumor volume was no difference between the control and chemotherapy groups(P>0.05).However,the white blood cell count in the radiotherapy group was significantly higher than that in the conventional chemotherapy group(P<0.05).Conclusion Capecitabine chemotherapy at continuous low-dose inhibits neovascularization and adjusts the proportion of immune cells to suppress tumor formation.Thus,this chemotherapy could reduce side effects caused by chemotherapy and improve the quality of life.

Objective To investigate the influence of intrahepatic cholestasis of pregnancy (ICP) on the pulmonary morphologic changes of fetal rats.Methods Twenty pregnant SD rats at 15 days of gestations were randomly divided into ICP and control group.Rats in the ICP group were subcutaneously injected with 17-α-ethinylestradiol and progesterone for 5 consecutive days to establish the rat ICP model, and those of the control group received subcutaneous injection of sirasimeyu also for 5 days.The levels of serum alanine aminotransferases (ALT), aspartate transamlnase (AST), and total bile salt (TBA) were measured before and after the treatment, respectively.Maternal rats were sacrificed on 21 days of gestations and hysterotomies were performed immediately.Histopathologic changes of mammal rats' livers and fetal lungs were observed under light and electron microscopes.Results (1) The maternal serum levels of ALT, AST, and TBA showed no significant difference between the ICP and control group [ALT: (55 ± 15) vs (49 ±12) U/L; AST:(146±16)vs (145±20) U/L; TBA: (13±4) vs (14 ±4) μmol/L, P>0.05, respectively]before the ICP models were established, but higher levels were shown in the ICP group after [ALT: (94±12) vs (59±17) U/L; AST: (245±26) vs (163±27) U/L; TBA: (44±16) vs (17± 3) μmol/L, P <0.05, respectively].(2) The livers of maternal rats' in the ICP group were gloomy with blurred margins, however those of the control group were normal.Microscopic observed swollen and degenerated hepatocytes with narrowed hepatic sinusoid, dilated bile duct and necrosis of hepatocytes occasionally in the ICP group, while the morphology of hepatocytes and structures of lobuli hepatis in the control group were normal.(3) The fetal pulmonary tissues in the ICP group were dark, and normal in the control group.Histopathologic examination showed matured fetal pulmonary tissues with dilated and congested interstitial lung capillaries, thickened alveolar septum, mild focal inflammatory exudation and focal hemorrhage in alveolus.Furthermore, reduced microvilli, mitochondrion vacuolization, cytoplasm disintegration and increased lamellar body evacuation were observed in type Ⅱ pneumonocytes in ICP group under light and electron microscopes.While fetal pulmonary tissues of the control group did not show any significant lesions.Conclusions Rat model of ICP can be established with the combination of estrogen and progestin.Hyperbileacidemia in ICP rat may lead to pathological changes in fetal pulmonary tissues.
