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

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.

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

Aim To observe the effect of hemodialysis on pharmacokinetics of sparfloxacin in thepatients contracting chronic renal failure. Methods Sparfloxacin concentrations inserum and urine of hemodialysis and non-dialysis patients were measured with a highperformance liquid chromatography method after administration a single oral dose of 200mg sparfloxacin. The pharmacokinetic parameters were computed with the programPKBP-N1.Results The main pharmacokinetic parameters in hemodialysis group wereT1/2(ka) - (1. 25 ?0. 57) h, T1/2(?) = (11. 88?4. 13) h, Tpeak = (4. 18 ? 0. 78) h,Cmax = (0.80 ? 0. 17) mg? L-1 and AUC0-= (6. 90 ? 3. 25) mg?h?L-1, while innon-dialysis group were T1/ 2(ka) = (1. 12 ? 0. 42) h, T1/ 2(?) = (15. 93 ? 5. 20) h, Tpeak =(3. 88 ? 0. 75) h, Cmax = (0. 69 ? 0. 37) mg?L -1, AUC0-= (10.05 ? 4. 13) mg?h?L-l. The original sparfloxacin discharge rats in urine within 24 h were (8. 98 ? 3. 92) % and(10. 58 ? 5. 64) % separately. T1/2(?) and AUC in hemodialysis group were markedly lowerthan in non-dialysis group (P

Objective To investigate the regulatory effects of tuberculin on growth and apoptosis of liver cancer and lung cancer cell lines. Methods HePG2(liver cancer) and A549(lung cancer) cell lines were treated with TB supernatant(TB-SN) with different concentrations. Cell viability was detected by using LIVE/DEAD Viability/Cytotoxicity cell kits including specific fluorescence primer,and cell apoptosis was detected by Vybrant apoptosis assay. Results After treatment with 5% TB-SN for 5 d,cell apoptosis was significantly increased in HePG2 and A549 cell lines.Cell growth of HePG2 and A549 cell lines was inhibited after treatment with TB-SN. Conclusion Tuberculin can induce cell apoptosis and inhibit cell growth of liver cancer and lung cancer cell lines.

(3S)-Linalool synthase (LIS) is a key enzyme involved in the monoterpene biosynthetic pathway. Based on our previous transcriptome study, the expression level of LIS gene was exceedingly related to glycyrrhizic acid (GA) biosynthesis. Therefore, we used hairy root culturing to further investigate the effect of LIS on the GA biosynthesis. A LIS gene (GenBank accession number: MZ169552) was cloned from Glycyrrhiza uralensis. The plant binary overexpression vector pCA-LIS was constructed by gene fusion. G. uralensis hairy roots overexpressing LIS were induced by the Agrobacterium rhizogenes ATCC15834. The expression levels of LIS were analyzed by real-time quantitative PCR (RT-qPCR) and the contents of GA in hairy root lines were determined by UPLC. It was found that in the hairy root lines overexpressing LIS, the expression levels of LIS were significantly higher than that in the wild type, while the contents of GA were remarkably lower than those in the wild type and negative control. These findings indicate that the expression level of LIS is negatively correlated with the accumulation of GA. In this study, LIS was cloned from G. uralensis for the first time and the negative regulatory effect of LIS on GA biosynthesis was confirmed by reverse genetics. This work provides support for further improvement of the molecular regulatory network of GA biosynthesis in G. uralensis.

Objective To investigate the 5-and 10-year survival and complications of patients with stage Ⅱb cervical carcinoma treated by pre-operative photon radiotherapy (POPRT) plus brachytherapy (192Ir) and selective lymphadenectomy hysterectomy (SLH) plus intra-operative electron radiotherapy (IOERT). Methods From February 1997 to May 2007, 160 patients with stage Ⅱb cervical carcinoma were treated by POPRT of 20 Gy in 10 fractions to the whole pelvis, 192Ir brachytherapy of 14 Gy in 2fractions, followed by IOERT of 18 -20 Gy to the whole pelvis during SLH one week after. Results The follow-up rate was 98.1%. The number of patients followed-up for 5 and 10 years was 143 and 135,respectively. The 5-year overall survival rate, disease-free survival rate and local control rate of all patients were 89.4%, 86. 3% and 96. 3%, with the corresponding 10-year rates of 84.4%, 81.0% and 95.0%,respectively. The radiation-induced rectitis and cystitis were 5.0% and 0. 6%, respectivly. The rate of hydronephrosis and lower extremity edema was 6. 3% and 1.3%, respectively. Conclusions Combination of EBRT plus 192Ir brachytherapy and SLH plus IOERT could improve the survival and local control of patiens with cervical carcinoma, with only a few side effects.
