Bone marrow mesenchymal stem cells(BMSCs) are a population of multipotent cells. Many researchers have studied whether BMSCs could differentiate into neurons in vivo and ex vivo. Although some studies didn't agree with about some chemical induction medium inducing neurons, the application of cell transplantion and gene therapy of BMSCs has achieved certain progress showing good future for BMSCs in therapy of nervous system diseases.

Objective To investigate the factors affecting rural women suffering from postpartum depression in order to provide scientific basis for rational intervention.Methods 368 rural pierperas whose deliveries were in the First Affiliated Hospital of Shanxi Medical University were surveyed by trained professional nurses with the Edinburgh Postnatal Depression Scale from May 1,2013 to April 30,2014.The data were processed by chi square test and unconditional logistic regression analysis to find the independent risk factors associated with postpartum depression.Results There were 347 valid questionnaires.The incidence of depression after delivery was 25.1% (87/347).Logistic regression analysis showed that the low income family [OR=1.982 (1.238-2.562)],the inconformity of actual and expected baby gender [OR=0.465 (0.183-0.759)] and the mother-in-law as caregiver of pierpera [OR=2.459 (1.950-2.913)] were independent risk factors for postpartum depression of rural women,three of them are significant statistically,P<0.05.Conclusions Understanding the risk factors for postpartum depression and being targeted to guide individually can reduce the incidence of postpartum depression.

AIM To analyze the effects of endomorphins (EMs) and their analogs ([D-Pro2]EM-1, [D-Ala2]EM-1, [D-Pro2]EM-2 and [D-Ala2]EM-2) on the cardiovascular system of anesthetized rats and to study its mechanism. METHODS Responses to EMs and their analogs were investigated in the systemic vascular bed of rats and the mesenteric microarteria of Bufo gargarizans. Responses to EMs were investigated on the hindquarters of the rat vascular bed under constant-flow conditions and on the isolated rabbit thoracic aorta strips. RESULTS The EMs and their analogs showed dose-related (10-9-10-6 mol*L-1, iv) and naloxone-sensitive (2 mg*kg-1, iv) hypotension in mean arterial pressure of rats with similar duration and vasodilatation in mesenteric microarteria of Bufo gargarizans. The sequence of potencies was EMs > [D-Pro2]EM-2 > [D-Ala2]EM-2 > [D-Ala2]EM-1 > [D-Pro2]EM-1. EMs were shown not to relax the isolated rabbit thoracic aorta strips without endothelium. EMs, however, relaxed them with endothelium significantly. This action was blocked by Nx (10-5 mol*L-1) and L-NNA (10-4 mol*L-1). CONCLUSION The significant hypotensive activity of EMs and their analogs is mainly associated with their vasodilatation, which is related to the release of NO from vascular endothelium, and their potency is not completely related to their affinity for μ-opiate receptor.

Objectives: To study the ameliorated effect of recombinant growth hormone on protein metabolism in chronic abdominal infection. Methods: 20 patients were divided randomly into two groups. Patients in the control group received TPN only for 10 days, while patients in the GH groups received both rGH(13.5u/d) and TPN for 10 days. Sepsis Score grade and detection of serum Growth Hormone (GH), Insulin like growth factor-1 (IGF-1), and Insulin like growth factor binding protein- 3(IGFBP-3) were carried out on day 0 and day 11, Serum albumin, prealbumin, transferring, fibronectin and C-reaction protein were detected on day 0, day 3, day 7 and day 11, Nitrogen balance and 24-hour urine creatinine secretion were assayed daily. Results: GH, IGF-1 and IGFBP-3 in the GH group on day 11 were significantly higher than those in the GH group on day 0 and those in the control group on day 11, Serum albumin, prealbumin, transferring and fibronectin increased, while C-reaction protein decreased when patients were undertaken GH treatment, Nitrogen balance ameliorated and accumulative total nitrogen balance in the GH group was significantly higher than that in the control group, while 24-hour urine creatinine secretion decreased. Conclusions: Recombinant growth hormone can ameliorate protein metabolism in chronic abdominal infection. IGF-1 plays important role in the ameliorated effect of recombinant growth hormone on protein metabolism in chronic abdominal infection.

BACKGROUND:Previous in vitro studies mainly focused on morphological and nerve marker aspects in the study of bone marrow mesenchymal stem cells (BMSCs)-derived neuron-like cells,but less focused on the olectrophysiological properties of neuron-like cells following differentiation.OBJECTIVE:To study the electrophysiological changes of differentiation from BMSCs into neuron-like cells after induction by brain-derived neurotrophic factor (BDNF)/basic fibroblast growth factor (bFGF)/alltrans-retinolc acid (AT-RA).DESIGN,TIME AND SETTING:The cytological comparative in vitro study was performed at the Department of Neural Cell Laboratory,Tianjin Huanhu Hospital and College of life Science of Nankai University from June 2005 to October 2007.MATERIALS:Totally 3 male Wistar rats (6-week old,weighing about 160 g) were used in this study.METHODS:BMSCs were cultured and purified by their characteristic of plastic adhesion in vitro,and then induced by BDNF,bFGF and AT-RA,and differentiate into neuron-like cells.Whole-cell patch damp technique was used to detect cell membrane current prior to and 3 days following induction.MAIN OUTCOME MEASURES:MSC phenotype was determined by flow cytometry.Cell morphology was observed under the inverted microscope before and after differentiation.Neuron specific enolase expression was assessed by immunocytochemistry.Whole-cell current results were measured.RESULTS:Flow cytometry results demonstrated that CD90 positive rate (99±3)%,CD31 (3.4±0.8)%,and CD34 (0.3±0.1)%.This indicated that these cells were undifferentiated stem cells,with purity of 95%.Undifferentiated MSCs under the optical microscope were mostly fiat cells with processes,similar to fibroblast-like cells.Neuron-like cells appeared 3 days following induction.Immunocytochemistry results showed that MSCs before induction were weakly positive for neuron specific enolase,but strongly positive for neuron specific enolase.At 72 hours,the differentiated rate was (24.01±3.76)%.The peak currents of outward currents in neuron-like cells were significantly higher in the induction group compared with the control group (P < 0.05),but no inward Na~+ current was detected.CONCLUSION:(bFGF & BDNF)/AT-RA could induce the differentiation of MSCs into neuron-like cells.These cells showed the tendency to differentiate into mature neurons,though having no electrophysiological properties of mature neurons.

Objective To evaluate the capability of strain rate imaging(SRI)for monitoring regional systolic deformation and synchronicity of left ventricle after coronary artery bypass graft(CABG)and for evaluating effect of surgery and predicting restenosis.Methods The values of systolic strain rate(SRsys),systolic strain(Ssys)and post systolic strain index(PSI)in 5 segments supplied by left anterior descending coronary artery were measured in study group(60 patients with coronary artery disease)at 1 day before and 10 days,1 month,3 months and 6 months after CABG.Forty healthy participants served as a baseline control group.The regional myocardial function before and after CABG was compared and analyzed.Results The peak values of SRsys and Ssys decreased before CABG in study group.In 52 of the 60 patients,SRsys and Ssys in the graft segments increased gradually and showed statistical significance in most studied segments at 3 and 6 months after surgery.In the above 52 patients,value of PSI increased before CABG and reduced significantly in all analyzed segments at 6 months after surgery.The restenosis of graft artery was suspected in 8 patients by SRI and the positive predictive value was 75%.The diagnosis sensitivity of SRI parameter method was higher than that of 2-dimensional echocardiography and the sensitivity of Ssys was higher than that of SRsys.Conclusions SRI can be used to quantitatively assess the regionsl systolic deformation and synchronicity and monitor the improvement of myocardial function after CABG and determine the effect of surgery and predict restenosis of graft artery.
