Stroke is one of the most common diseases among middle and senior - aged people,and depressive disorder,which hinders severely recovery and prognosis,is one of the complications of stroke.This paper analyzes the efficiency of social intervention mode on patients with post - stroke depressive disorder,and comes up with the conclusion that social intervention mode can not only help to ameliorate the occurrence of post - stroke depressive disorder,but also promote the recovery of patients' nervous function.Therefore,the social intervention mode can be regarded as an effective means for medical treatment.

Objective To investigate the influence of propofol on the induction of inducible nitric oxide synthase (iNOS) expression in spinal cord after spinal cord injury (SCI) in rats. Methods SCI model was reproduced according to Allen′s method with modification. Seventy-four SD rats were randomly divided into three groups: normal group (n=4), SCI with propofol treatment group (n=35), and SCI with saline treatment group (n=35). Immunohistochemistry and Western blot were employed to detect iNOS expression in spinal cord at different time (1h, 3h, 8h, 1d, 3d, 7d, 14d). Results The results showed that iNOS expression in spinal cord of propofol treatment group was significantly decreased compared with that of saline treatment group (P

Objective: Huperzia serrata, whose growth is limited by high temperature, is a rare medicinal plant with the treatment function for Alzheimer's disease (AD). To research the effect of high temperature on the structure and function of cell membrane and chloroplast, and to provide the evidence for production practices. Methods: H. serrata was processed at 25, 30, 35, and 40°C, respectively, then the content changes of malondial dehyde (MDA) and conductivity rate, and the content changes of total chlorophyll, chlorophyll a, chlorophyll b, and chlorophyll a/b values were measured. The changes of the chloroplast ultra microstructure were observed under the transmission electron microscope (TEM). Results: The changes of MDA and conductivity rate in the process at 35 and 40°C were significantly higher than those of the control group; After processed at 40°C for 4 d, the total chlorophyll was decreased significantly, and became the lowest on the day 6, just was 58% compared to the control group; the change trends to the contents of chlorophyll a, chlorophyll b, and total chlorophyll were similar; TEM observation revealed that after processed at 35°C for 4 d, the chloroplast structure appeared deformation, and after processed at 40°C for 4 d, the chloroplast structure subjected obvious destruction capsule fuzzy, fracture in different degrees, thylakoid in disorder, matrix lamellar irregular, and so on. Conclusion: According to the changes of physiological index, ultramicroscopic structure, and external morphology of chloroplast, the suitable temperature for H. serrata is 25-30°C, 40°C is the limited temperature, causing death after 4 d stress, and 35°C has obvious impact on the growth, long-time stress in 35°C could also cause plant deaths.

Objective: To establish and analyze the HPLC characteristic chromatogram for water extracts of Arisaematis Rhizoma (AR) and its processed products, Arisaematis Rhizoma Preparatum (ARP) and Arisaema Cum Bile (ACB). The research provided reliable method and scientific basis for their quality control. Methods: The separation was performed on an Agilent C18 (200 mm × 4.6 mm, 5 μm) column with gradient elution of 0.2% acetic acid water and 0.2% acetic acid acetonitrile. The similarity was analyzed with software “Similarity Evaluation System for Chromatographic Fingerprint of TCMs (Version 2012)”. The cluster analysis was performed by SPSS 23.0. The principal component analysis was performed by SIMCA 14.1. Results: HPLC characteristic chromatogram for water extracts of AR, ARP, and ACB were established. There were 19, 20 and 13 common peaks in AR, ARP and ACB, respectively. A total of eight characteristic peaks were identified as F1 (xanthine), F3 (uracil), F4 (hypoxanthine), F5 (uridine), F6 (guanosine), F7 (adenosine), F14 (schaftoside), and F16 (isoschaftoside), respectively. The intragroup similarities of AR, ARP, and ACB were all above 0.8 and each was clustered into one type, and the intergroup similarities among AR and its processed products were all below 0.4. The main components of AR were F16 (isoschaftoside), F14 (schaftoside), F17and F15. The main components of ARP were F16 (isoschaftoside) and F1 (xanthine). The main components of ACB were F3 (uracil), F2, F5 (uridine) and F1 (xanthine). Conclusion: The method can effectively identify AR, ARP and ACB, and provide a scientific basis for their quality control.

Objective To analyse the clinicopathological features of primary small intestine lymphoma(PSIL), and explore the relationship between clinical stage,histological findings,therapeutic modality and prognosis. Methods The clinical data of 34 cases of PSIL were collected,the pathohistological features and results of immunohistochemical examinations were obtained,and the follow-up findings were adopted for comprehensive analysis. Results Among these 34 cases of PSIL,abdominal pain or discomfort,gastrointestinal bleeding and abdominal mass were the predominant symptoms.PSIL mainly involved ileum,especially the bottom of ileum and ileocecal area.Among the 26 patients with follow-up for more than one year,the 1-year survival rate was significantly higher in patients without tumor perforation than those with tumor perforation(76.2% vs 20.0%)(P

OBJECTIVETo investigate the effect of extracellular regulating kinase (ERK) signaling pathway on the secretion of gamma-aminobutyric acid (GABA) in cultured rat hippocampal neurons induced by stromal cell derived factor-1 (SDF-1).

METHODSThe hippocampal neurons of newborn SD rats were cultured and identified in vitro; the phosphorylation level of ERK1/2 was examined by Western blot; ELISA was used to detect the effect of PD98059, a ERK1/2 specific blocker on GABA secretion of cultured hippocampal neurons and Western blot were adopted to measure the protein expression levels of glutamate decarboxylase (GAD65/67) and gamma aminobutyric acid transporter (GAT); after blocking ERK1/2 signaling pathway with PD98059; RT-PCR was used to detect the mRNA expression levels of GAT-1 and GAD65 after treated with PD98059.

RESULTSThe levels of ERKl/2 phosphorylation were increased significantly by SDF1 acting on hippocampal neurons, and CX-CR4 receptor blocker AMD3100, could inhibit SDF-1 induced ERK1/2 activation; SDF-1 could inhibit the secretion of GABA in cultured hippocampal neurons, and ERK1/2 specific inhibitor PD98059, could partly reverse the inhibition of GABA secretion by SDF-1. The effects of SDF-1 on cultured hippocampal neurons was to decrease the mRNA genesis of glutamic acid decarboxylase GAD65 and GABA transporter GAT-1, besides, ERK inhibitor PD98059 could effectively flip the effect of SDF-1. The results of Western blot showed that SDF-1 could inhibit the protein expression of GAT-1 and GAD65/67 in hippocampal neurons and the inhibition of GAT-1 and GAD65/67 protein expression could be partially restored by ERK1/2 blocker.

CONCLUSIONSDF-1 acts on the CXCR4 of hippocampal neurons in vitro, and inhibits the expression of GAD by activating the ERK1/2 signaling pathway, and this may represent one possible pathway of GABA secretion inhibition.
