Endothelial injury or dysfunction leads to multiple cardiovascular diseases, such as atherosclerosis, myocardial infarction, stroke, hypertension and peripheral vascular disease. Endothelial progenitor cells (EPCs) are precursor cells of endothelial cells, including the early endothelial progenitor cells and the late endothelial progenitor cells. hTese two EPC types have different function and surface markers. EPC in this article mainly means late endothelial progenitors which could grow into endothelial cloning and form vessels in vivo. Late EPCs can express CD133, CD31, KDR, CD144, CD34 etc, take in low density lipoprotein, bind with ulex europaeus lectin 1 and form blood vessels in vitro and in vivo. EPCs not only participate in new blood vessels formation, but also are closely related to the repair of damaged endothelium. Many studies conifrm that the transplanted EPCs are able to be mobilized to vascular injury location and repair the damaged endothelial cells thus promote new blood vessel formation, which provides a promising strategy for the treatment ofcardiovascular diseases and ischemic diseases.

Objective To evaluate the pregnancy outcome of women with pulmonary arterial hypertension (PAH).Methods The medical records of 103 pregnant women with PAH admitted to Beijing Anzhen Hospital from January 2007 to March 2011 were studied retrospectively.Results (1) Degree of PAH and cardiac function.Among the 103 PAH,92 cases were patients with congenital heart disease and 13 cases were with rheumatic heart disease.They were divided by color doppler ultrasound into mild PAH group (34 cases),moderate PAH group (22 cases) and severe PAH group (47 cases).Per heart function classification,21 cases (20.4％,21/103) were class Ⅰ,44 cases (42.7％,44/103) were class Ⅱ,27 cases (26.2％,27/103) were class Ⅲ and 11 cases (10.7％,11/103) were class Ⅳ.More patients were class Ⅲ and Ⅳcardiac function in the severe PAH group than in the mild and moderate PAH groups,with statistically significant difference (P ＜ 0.05).(2) Delivery mode.There were 44 term delivery and 23 preterm birth in the 103 PAH patients.Sixty-three cases (94％,63/67) received cesarean section and 4 cases had vaginal delivery.There were 36 iatrogenic abortion (35.0％,36/103).The iatrogenic abortion rate in the severe PAH group was significantly higher than those in the mild and moderate PAH groups (P ＜ 0.05).(3) Perinatal outcomes.The full-term delivery rates in the mild and moderate PAH groups [80％ (20/25) and 14/17] were significantly higher than the severe PAH group (40％,10/25),respectively (P ＜ 0.05).And the premature birth rate of the severe PAH group(60％,15/25) was significantly higher than the mild and moderate PAH group [20％ (5/25)and 3/17,P ＜ 0.05].There were 4 neonatal asphyxia.The birth weight of mild,moderate and severe PAH groups were (3071 ± 443),(2910 ± 619) and (2381 ±589) g,respectively.The birth weight in the severe PAH group was significantly lower than the mild and moderate PAH groups (P ＜ 0.05).(4) Mortality.Nine cases naternal death happened,with a mortality of 8.7％ (9/103).All of them were severe pulmonary hypertension patients.Conclusions PAH is a serious complication during pregnancy.Women with mild PAH and normal cardiac function could continue pregnancy to full-term.Women with moderate PAH might continue pregnancy to 32 weeks under intensive care,cesarean delivery is preferable.Pregnant women with severe PAH should terminate pregnancy because of the high mortality.

cFos is one of the most widely-studied genes in the field of neuroscience. Currently, there is no systematic database focusing on cFos in neuroscience. We developed a curated database-cFos-ANAB-a cFos-based web tool for exploring activated neurons and associated behaviors in rats and mice, comprising 398 brain nuclei and sub-nuclei, and five associated behaviors: pain, fear, feeding, aggression, and sexual behavior. Direct relationships among behaviors and nuclei (even cell types) under specific stimulating conditions were constructed based on cFos expression profiles extracted from original publications. Moreover, overlapping nuclei and sub-nuclei with potentially complex functions among different associated behaviors were emphasized, leading to results serving as important clues to the development of valid hypotheses for exploring as yet unknown circuits. Using the analysis function of cFos-ANAB, multi-layered pictures of networks and their relationships can quickly be explored depending on users' purposes. These features provide a useful tool and good reference for early exploration in neuroscience. The cFos-ANAB database is available at www.cfos-db.net .
