BACKGROUND:The effect of placenta-derived growth factor(PLGF)on promoting vascular regeneration remains uncertain.In studies of models with PLGF deletion,PLGF has been considered to play critical role in inducing angiogenesis.OBJECTIVE:To summarize the research advances in effect of PLGF and its receptor in vascular regeneration and ischemic cerebral disease.METHODS:A computer-based online search of Pubmed and CNKl was performed for relevant articles published between 1990 and 2009 with key words of"PLGF"in Chinese and"PLGF angiogensis"Articles related with biological characteristics of PLGF and its roles in vascular regeneration and articles related with angiogenesis and PLGF expression after cerebral ischemia were selected.Repetitive articles were excludedRESULTS AND CONCLUSION:The role of PLGF and its receptor in vascular regeneration,mechanism of PLGF and its receptor to promote angiogenesis,vascular endothelial growth factor A,and the expression of PLGF and its receptor in brain after cerebral ischemia were introduced.PLGF can promote pathological angiogenesis,arteriogenesis,branch formation and hemopoietic progenitor cell mobilization.PLGF and its receptor play an important role in the angiogenesis of ischemic cerebral disease and display a good clinical prospect in the treatment of ischemic cerebral disease However,the specific role and mechanism require further study.

Dystrophinopathies are a group of fatal X chromosome recessive genetic disease. With the application of ventilator technolo-gy, the main causes of death in patients with dystrophinopathies turned from respiratory failure into circulatory failure, and the importance of heart problems has become increasingly prominent. Myocardial damage can be defined with myocardial enzymes, electrocardiogram, ul-trasound cardiogram, cardiac magnetic resonance imaging, etc. Drugs for chronic heart failure remain the most important strategy, and heart transplant or left ventricular assist devices implant may be the alternatives for those in the end.

Objective To explore the relationship between critical thinking disposition and mental self-supporting and provide reference for educators in an attempt to improve undergraduate nursing students' positive psychological qualities and critical thinking disposition.Methods A total of 406 nursing undergraduates were investigated by using the California Critical Thinking Disposition Inventory-Chinese Version (CCTDI-CV) and Mental Self-supporting Questionnaire of University students.Results Undergraduate nursing students scored (280.91± 28.43) points averagely in critical thinking disposition,and the dimensions of analyticity (42.17±5.31) and truth seeking(37.56±6.42) got the highest and lowest score respectively.The total score of mental self-supporting was 76.40±8.47 points; among the seven subscales,opening and containing(11.90± 1.72) scored the highest and self-conviction(8.87±2.28) scored the lowest.A positive association was found between critical thinking disposition and mental self-supporting(r=0.583,P＜0.01).The regression analysis showed that students' self-decision,self-cognition,self-confidence and self-charge played a significant role in students' critical thinking disposition (R2=0.435,P＜0.01).Conclusion Undergraduate nursing students' disposition of critical thinking and mental self-supporting were on medium level.The subscales of self-decision,self-cognition,self-confidence and self-charge have huge influence on critical thinking disposition.Nursing educators should make an effort in the above 4 aspects so as to improve undergraduate nursing students' critical thinking disposition.

Objective To analyze the complications of pregnant secondary cesarean in scar uterus,to provide theoretical guidance for cesarean section.Methods 160 pregnant women of secondary cesarean uterine scar were chosen as the study group.80 pregnant women of non-scar uterine were chosen as the control group.Results The bleeding volume during operation,operation time,operation fee,postoperative bleeding,uterine resection rate,neonatal asphyxia in study group were (432 ± 331) mL,(64 ± 21) min,(0.91 ± 0.11) million,(262 ± 187) mL,4.4％,11.9％,which in the control group were (361 ± 209) mL,(44 ± 16) min,(0.63 ± 0) million,(184 ± 132) mL,1.3％,6.3％ respectively,the differences were significant (t =2.52,8.19,26.10,4,4.76,x2 =3.98,all P ＜ 0.05).The two groups had no statistically significant difference in organ damage situation (P ＞ 0.05).Conclusion Secondary cesarean uterine scar easily lead to maternal blood loss and increased postoperative bleeding,prolonged surgery,increased hysterectomy rate,increased incidence of neonatal asphyxia and other complications.Pregnant uterine scar pregnancy is a high-risk pregnancy,pregnancy for maternal uterine scar secondary surgical indications should be strictly controlled.

To examine the role of glycogen synthase kinase 3 (GSK-3) in the apoptosis of pancreatic beta-cells to better understand the pathogenesis and to find new approach to the treatment of type 2 diabetes, apoptosis was induced by oleic acid (OA) in INS-1 cells and the activity of GSK-3 was inhibited by LiCl. The PI staining and flow cytometry were employed for the evaluation of apoptosis. The phosphorylation level of GSK-3 was detected by Western blotting. The results showed that OA at 0.4 mmol/L could cause conspicuous apoptosis of INS-1 cells and the activity of GSK-3 was significantly increased. After the treatment with 24 mmol/L of LiCl, a inhibitor of GSK-3, the OA-induced apoptosis of INS-1 cells was lessened and the phosphorylation of GSK-3 was increased remarkably. It is concluded that GSK-3 activation plays an important role in OA-induced apoptosis in pancreatic beta-cells and inhibition of the GSK-3 activity can effectively protect INS-1 cells from the OA-induced apoptosis. Our study provides a new experimental basis and target for the clinical treatment of type-2 diabetes.
