Aim To explore the role of nicotinamide adenine dinucleotide phosphate ( NADPH ) oxidase in high glucose-induced injury in H9c2 cardiac cells. Methods H9 c2 cardiac cells were exposed to differ-ent concentrations of high glucose(5. 5 mmol·L-1 ,11 mmol · L-1 ,22 mmol · L-1 ,33 mmol · L-1 ,44 mmol ·L-1 , 55 mmol · L-1 ) for 24 h and different time pints of high glucose(0 h,12 h,24 h,36 h,48 h,72 h) . Cell viability was measured by MTT colorimetry, the protein expression of Bcl-2 , Bax and NADPH oxi-dase submits such as p22 phox , p47 phox and p67 phox were determined by western blotting. Results H9c2 cardi-ac cells exposure to high glucose for 24 h showed on decrease in cell survival and the Bcl-2 expression while an increase in the Bax expression ( P<0. 05 ) . Moreo-ver, high glucose could markedly up-regulate the activ-ity of NADPH oxidase characterized by the enhanced expression of p22 phox , p47 phox and p67 phox ( P<0. 05 ) . Conclusion Activating NADPH oxidase may play an important role in high glucose-induced injury in H9 c2 cells.

Objective To study the influence of interleukin-11 (IL-11) on graft versus host disease(GVHD) and graft versus leukemia(GVL) after allogenic bone marrow transplantation and related mechanism in acute lymphoblastic leukemic(ALL) junior mice.Methods The impact of IL-11 on CD4 and CD8 T cell after transplantation was evaluated by flow cytometry;it was observed that the GVHD pathology chance of internal after transplatation in ALL junior mice;the survial time after transplantantion was recorded;the level of tumor necrosis factor-?(TNF-?) which evidently related to GVHD was evaluated by ELISA.Results IL-11 could decrease the quantity of CD4 T cell and increase CD8 T cell;IL-11 could obviously increase the survival time and decrease the level of TNF-?. After ALL junior mice transplatated,IL-11 could delay and relieve GVHD.Conclusion IL-11 can alleviate GVHD and retain the effect of GVL after allogenic bone marrow transplantation.

Objective To study the expression profile of microRNA (miRNA) and the roles in pathogenesis of acute liver failure in mouse model. Methods Eighty-five BALB/c mice were divided into four groups: 40 in model group of acute liver failure were intraperitoneally injected with Dgalactosamine (D-GalN) and lipopolysaccharides (LPS); 20 in D-GalN group were injected with DGalN only; 20 in LPS group were injected with LPS only; 5 in control group were injected with saline.Liver histology of mouse was observed at hour 0, 5, 7 of injection, and sera and liver tissues were collected at hour 0, 1, 3, 5, 7, 9 of injection. Meanwhile, levels of inflammatory factors [tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)] in serum and liver tissue were detected by realtime polymerase chain reaction (PCR). Lock nucleic acid (LNA)-based miRNA microarray technology was used to detect the expression profile of hepatic miRNA, and the expression of miRNA was verified by real time quantification-polymerase chain reaction (RT-PCR). Mouse macrophage Raw264.7 cells were induced by LPS in vitro and the expressions of miRNA at different time points were detected.The comparison of means among groups was analyzed using one way ANOVA and the correlation were analyzed by Pearson and Spearman correlation. Results Microarray analysis found that the expression profile of miRNA during the acute liver failure changed dramatically. There were 97 miRNA in model group changed significantly compared with control group (P＜0.01), including 21 up-regulated and 27down-regulated at hour 5 and 7 of injection. Furthermore, the expressions of miR 146a and miR-155were verified by RT-PCR and found they both increased progressively over time after injection.Correlation analysis showed that miR-155 was well correlated with both TNF-α and IL-6 expressions.It was further found that miR-146a and miR-155 were both up-regulated in activated Raw264.7 cells in vitro. Conclusions The expression profile of miRNA changes during acute liver failure in mouse model. Inflammation associated-miR-146a and miR-155 are both up-regulated significantly, which indicatcs that they may play an important regulatory role in pathogenesis of acute liver failurc.

Objective To assess the effectiveness of repeated trans-cranial magnetic stimulation ( rTMS) in relieving post-stroke depression ( PSD). Methods PubMed, Embase, the Cochrane library, Web of Science, CNKI, WANFANG, and VIP were searched for reports of randomized, controlled trials of rTMS treatment of PSD published before June 2015. Crude standardized mean differences ( SMDs) and odds ratios with 95% confidence in-tervals ( CIs) were calculated for depression intensity and effectiveness rate after treatment using random or fixed effects models. Results Twenty-four studies involving 856 rTMS-treated patients and 802 control patients were in-cluded in the meta-analysis. The results showed that compared with the control group, PSD patients showed significant reductions in depression after rTMS treatment ( SMD=-1.36;95% CI-1.6 to-1.12;P≤0.05) . The total effective-ness rate in the treated group was 85% with a reduction in NIHSS score ( SMD=-0.82;95% CI-1.2 to-0.44;P≤0.05) . Subgroup analysis showed that neither the frequency of rTMS stimulation, the site stimulated, nor time after stroke had a significant influence on the effectiveness of rTMS. Additionally, a few studies reported adverse reactions after rTMS. Conclusion rTMS appears to be a safe and effective therapy for PSD. Further well-controlled trials may elucidate the mechanism underlying the placebo effects of the sham rTMS observed among PSD patients.

Objective:To observe the clinical effect of electroacupuncture (EA) plus pricking-cupping bloodletting therapy for herpes zoster.
Methods:A total of 43 patients with herpes zoster were randomly divided into two groups, 23 cases in the treatment group and 20 cases in the control group. The treatment group was given EA plus pricking-cupping bloodletting therapy. The control group was given oral administration of Aciclovir Tablets, Diclofenac Sodium Dual Release Enteric-coated Capsules, Methylcobalamin Dispersible Tablets, and V itamin B12.
Results: The total effective rate was 87.0% in the treatment group and 70.0% in the control group, with a statistical significance in difference of the total effective rate between the two groups (P<0.01).
Conclusion:The clinical effect is better in the treatment of herpes zoster by EA plus pricking-cupping bloodletting therapy than by medications.

Objective To investigate the expression of mannose-binding lectin (MBL) in lesions of patients with psoriasis vulgaris,and to explore the relationship between MBL and psoriasis pathogenesis.Methods Immunohistochemistry and Western blot were performed to detect the expression of MBL in lesional and normalappearing perilesional skin of 30 patients with progressive psoriasis vulgaris,as well as in normal skin of 30 healthy human controls.Statistical analysis was carried out by t test using SPSS13.0 software.Results Immunohistochemistry showed that MBL was expressed in lesional psoriatic skin,but weakly expressed or absent in normalappearing perilesional skin and normal control skin,with the relative expression level of MBL in lesional skin significantly higher than that in perilesional skin and normal control skin (0.636 7 ± 0.515 1 vs.0.416 3 ± 0.160 1 and 0.381 6 ± 0.310 9,t =2.24,2.32,respectively,both P ＜ 0.05).Western blot revealed a positive expression of MBL protein in all the skin specimens,and the expression intensity of MBL protein in lesional psoriatic skin was significandy increased compared with perilesional psoriatic skin and normal control skin (0.273 1 ± 0.129 4 vs.0.186 3 ± 0.193 1 and 0.149 2 ± 0.268 7,t =2.05,2.28,respectively,both P＜ 0.05).No significant difference was shown in the expression of MBL protein between perilesional psoriatic skin and normal control skin by immunohistochemistry (t =1.51,P ＞ 0.05) or Western blot (t =0.61,P ＞ 0.05).Conclusion There is a high expression of MBL protein in lesions of patients with psoriasis vulgaris,which may be somewhat associated with the pathogenesis of psoriasis.

Objective To determine the gene polymorphism and serum concentration of mannose-binding lectin (MBL) in patients with psoriasis,and to analyze the relationship between MBL and psoriasis.Methods Totally,67 patients with psoriasis vulgaris and 69 healthy human controls were enrolled in this study.Venous blood samples were obtained from all the subjects.Genomic DNA was extracted,and PCR-restriction fragment length polymorphism (PCR-RELP) analysis was conducted to determine the polymorphism at codon 54 of the MBL gene.Enzyme-linked immunosorbent assay was performed to measure the serum level of MBL.A chi-square goodness-of-fit test was carried out to evaluate Hardy-Weinberg equilibrium,t test to compare the serum concentration of MBL,and chi-square test to compare the frequency of genotypes and alleles of MBL gene codon 54.Results The patients with psoriasis showed higher frequency of GGC/GAC heterozygote but lower frequency of GGC/GGC homozygote (x2 =10.36,P ＜ 0.05),together with increased frequency of GAC allele but decreased frequency of GGC allele (x2 =8.31,P ＜ 0.05),at codon 54 of the MBL gene compared with the healthy controls.The variant allele GAC at codon 54 of the MBL gene was markedly associated with psoriasis (OR =3.383,95％ CI 1.585-7.211,P ＜ 0.05).The serum concentration of MBL was (2.193 7 ± 0.816 3) mg/L in patients with psoriasis,significantly lower than that in the healthy controls ((3.269 5±1.205 8) mg/L,t=6.11,P＜ 0.05).Conclusion MBL might be associated with the pathogenesis of psoriasis to some degree.
