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.

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.

Twenty days after the operation of anterior cervical decompression fusion with internal fixation, the fistula was found at the lower end of right neck incision with purulent secretion, the intumescent mucosa was founded at the posterior wall of the esophagus, down about 5 cm of the oesophagostomum. The metal plate sample exposed under the intumescent mucosa. The diagnosed was "neck esophageal fistula".

Objective To evaluate the changes of ventricular synchrony in patients with acute myocardial infarction(AMI)before and after percutaneous coronary intervention(PCI)by speckle tracking imaging(STI).Methods Thirty patients with AMI were examined by traditional echocardiography and STI before and 5 d,1 month after PCI.Myocardial imaging of left ventricular apical long views and parasternal left ventricular short axis views were recorded and stored.The time to peak longitudinal systolic and diastolic strain rate(TS-SRL,TE-SRL)and to peak radial systolic and diastolic strain rate(TS-SRR,TESRR)were measured respectively.The differences of the maximum and minimum systolic and early diastolic peak time(TSL-diff,TER-diff)and the standard deviation(TSL-SD,TER-SD)in 18 longitudinal segments were calculated.And the differences and standard deviation of TS-SRR and TE-SRR(TSR-diff,TSR-SD,TER-diff,TER-SD)were calculated also.These parameters were compared before and after PCI.Results Compared with before and 5 d after PCI,the values of TSL-diff,TSL-SD,TEL-diff and TEL-SD in 1 month after PCI were decreased significantly(P＜0.01).TSR-diff,TSR-SD,TER-diff and TER-SD were decreased also and the differences had statistical significance(P＜0.01).The cardiac synchronized index and LVEF values showed good negative correlation.Conclusions The systolic and diastolic synchrony of left ventricle in AMI patients was abnormal.STI can evaluate left ventricular synchronized function and the changes before and after PCI to assess the effect of PCI.

Objective To detect the effect of osthole on proliferation and apoptosis of HL-60 cells and its molecular mechanism.Methods HL-60 cells proliferation was measured through the CCK8 assay method.The cell morphological changes were observed by Hoechst33342 staining after 8 h of drug effect.Induction of apoptosis was determined by flow cytometry and fluorescent microscopy.Expressions of Bcl-2 and Bax mRNA were evaluated by RT-PCR,and the expressions of cleaved caspase-3,caspase-8,caspase-9,Fas and FasL were evaluated by using western bolt assay.Results Osthole could inhibit the proliferation of HL-60 cells,the maximum inhibiting rate was (90.7 ±4.5)％,F =138.46,P =0.000; the apoptosis rate was 33.6％,F =27.75,P =0.006.The changes of apoptosis of cells and nucleus were shown in cell morphological observation.Osthole affected the decrease of the mRNA levels of Bcl-2 and the increase of the Bax mRNA levels via a dosedependent manner(F =210.12,P =0.000).Western blotting demonstrated that osthole could lead to the increase of the expression levels of cleaved caspase-3,caspase-8,caspase-9,Fas and FasL in the HL-60 cell line via a time-dependent manner.Conclusion Data suggests that osthole inhibits proliferation and induces apoptosis of HL-60 cells through mitochondria-dependent pathway and death-receptor pathway.

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.

Endomorphins(EMs),two tetrapeptides, were discovered in 1997 and believed to be endogenous ligands of μ-opioide receptor(MOR). They mediated various physiological processes by binding to MOR that couple with G-proteins. Based on our works and literatures, we reviewed the distribution in nerve system, receptor binding properties, analgesis, effects on ion channels, conformation and struction-activity relationship of EMs.
