Objective To study the expansion and purification of human retinal progenitors cultured in vitro.(Methods Human) embryonic retinal progenitor cells(RPCs) were cultured.The characteristics of neural stem cell were observed.The expression of Nestin was examined flow cytometry(FCM) for the comparsion between the primary and secondary passages.The differentiation of RPCs had been observed after that they had been cultured in different conditions.Results Human RPCs had proliferated and formed cell clusters with a shape of neurosphere.After digestion,the scattered progenitors formed secondary neurosphere-like cell clusters.The cells in those clusters expressed Nestin and were negative for the mature retinal cell proteins.After spontaneous differentiation,the retinal progenitors expressed special proteins of mature retinal cells,including neuron specific enolase(NSE),glial fibrillary acidic protein(GFAP),protein kinase C(PKC) and Syntaxin-1.The expression of Nestin in the secondary culture passage was(39.3?18.9)%,which was significantly higher than that of the primary passage [(28.7?17.7)%](P

Radiotherapy is an important treatment for malignant tumors, but it will have a negative impact on the reproductive function of young female patients.In recent years, the measures to protect female fertility are increasing, including clinical mature technologies such as embryo cryopreservation and mature oocyte cryopreservation; highly experimental technologies such as immature oocyte in vitro fertilization and ovarian tissue cryopreservation and transplantation.In addition, the application of stem cells and the proposal of artificial ovary also show great prospects in the protection of female fertility.This paper reviews the research progress of female fertility protection strategies in radiotherapy.

Objective:To study the insulin resistance and leptin resistance in women with polycystic ovary syndrome(PCOS).Methods:Body mass index(BMI),serum leptin,fasting blood glucose(FBG),fasting insulin(FINS),serum triglyceride,total cholesterol,high-density lipoprotein,low-density lipoprotein and insulin resistance index(HOMA-IR) were assessed in 30 normal women,30 simple obesity women and 41 PCOS women.Results:①The PCOS patients showed higher levels of BMI,serum leptin,FINS,HOMA-IR and low-density lipoprotein,and lower levels of high-density lipoprotein than that in normal control.Compared to simple obesity women,there only showed higher FINS level and lower BMI in PCOS women.②Serum leptin levels in PCOS patients were concerned with BMI、FINS、HOMA-IR and serum triglyceride levels.③There were no significant difference of the FINS and HOMA-IR between normal women and non obese PCOS women,but the obese PCOS women showed higher levels of FINS and HOMA-IR than that in simple obesity women;the serum leptin levels showed no significant difference between normal women and non-obese PCOS women,simple obesity women and obese PCOS women. Conclusion:PCOS patients may have insulin resistance and leptin resistance;There may have regulative effect between leptin resistance and insulin resistance in PCOS patients;There are direct relationship between insulin resistance and PCOS;The rise of serum leptin level in PCOS women may be the assident manifestation of obesity.
