Objective To systematically evaluate the effectiveness and safety of resuscitation-inducing acupuncture for post-stroke dysphasia. Methods The randomized controlled trials ( RCTs) of resuscitation-inducing acupuncture for post-stroke dysphasia were searched in the domestic and overseas databases such as CBM, CNKI, Weipu VIP, Wanfang Data, PubMed, Web of Science, EMbase and the Cochrane Library ( from the founded date to December of 2014) . Literature screening, information extracting and literature quality assessment were done by 2 reviewers independently. RevMan5.3.0 software was used for Meta analysis. Results A total of 8 RCTs were included into the analysis, involving in 766 cases. The results of Meta analysis showed:( 1) for patients in the recovery stage of stroke, 4-week resuscitation-inducing acupuncture combined with routine treatment including internal medicine plus swallowing function training or not had better efficiency than the control group without resuscitation-inducing acupuncture (P<0.001) ; (2) for patients in the acute stage, the difference of efficiency between the combination group and the control group was insignificant (P=0.05); (3) The efficiency of resuscitation-inducing acupuncture combined with routine treatment for the complication of pulmonary infection stayed uncertain. Conclusion Resuscitation-inducing acupuncture combined with routine treatment is recommended to the patients with dysphasia in the recovery stage of recovery. But the cure time window, treatment course and effectiveness evaluation still need to be confirmed by more large-scale, high-quality randomized controlled trials.

Objective To study the expressions of α1-AT and VEGF-C in human bronchoalveolarcarcinorrm, and the relation of the expression to the patholo~cM differentiation and clinical stage. Methods All 49 Darffin embedding samples of patients with bronchoalveolar carcinoma were studied. α1-AT and VEGF-C were detected by immunohistochemical SP method.Automated image analyzer was used to quantify α1-AT and VEGF-C expressions.Results The immunohistochemical positive stainings of α1-AT and VEGF-C in brown or dark brown were located in cytopla8m.The expression levels of α1-AT and VEGF-C were not related with the gender,age,tumor position and size,and histology subtypos(P＞0.05).It Was found that the expression of α1-AT in patients with local lymph node metastasis was significantly lower than those without node metastasis(P＜0.001).It was found that the expression of VEGF-C in patients with local node metastasis significantly higher than th08e without node metastasis(P＜0.001).There Was a negative correlation between the expression level of α1-AT and the expression level of VEGF-C in bronchoalveolar carcinoma(r=-0.324,P＜0.05).Conclusion α1-AT and VEGF-C could be secreted by bronehoalveolar carcinoma.Bronehoalveolar carcinoma with lower α1-AT expression and higher VEGF-C expression is more likely to have lymph node metastasis.Lower α1-AT expression and higher VEGF-C expression can participate in the mechanism of lymph node metastasis in carcinoma together.

Objective To explore the impact of berberine on serum levels of insulin resistance and cytokines in schizophrenia patients treated with risperidone. Methods Sixty-four schizophrenia patients treated with risperidone were randomized to berberine group (n=31) and control group (n=33). The fasting plasma blood glucose (FBG) and fasting insulin (Fins) were detected before and after treatment in two groups. The homeostasis model assessment for insulin resistance (HOMA-IR) was calculated. The serum levels of interleukin (IL)-1β, IL-6, tumor necrosis factor-alpha (TNF-α) were evaluated by enzyme linked immunosorbent assay before and after the treatment. Results Compared with control group and pre-treatment group, the levels of FBG, Fins, HOMA-IR, IL-1β, IL-6 and TNF-α were significantly decreased after treatment in berberine group (P<0.05). The FBG level was significantly higher, the levels of IL-1β, IL-6 and TNF-αwere significantly lower, after treatment in control group (P < 0.01). There were no significant changes in Fins and HOMA-IR after treatment (P > 0.05). There was positive correlation between HOMA-IR and IL-1β, IL-6 and TNF-α in berberine group (r=0.316, 0.351 and 0.401, P<0.01). Conclusion Berberine can significantly decrease FBG, Fins, HOMA-IR, IL-
1β, IL-6 and TNF-α levels in schizophrenia patients treated with risperidone. The HOMA-IR level is closely correlated with IL-1β, IL-6 and TNF-αlevels.

Objective The purpose of this work was to compare the efficacy of narrow band imaging-assisted transurethral resection of bladder tumour (TURB) with conventional white light imagingassisted TURB in primary non-muscle-invasive bladder cancer.Methods Several databases were searched,including Cochrance Libarary,PubMed,Embase,Wanfang,VIP,CNKI and CBM.The endpoints were biochemical failure in 3 months,1 year and 2 years.We performed a meta-analysis of the published data.The results are expressed as risk ratio (RR),with the corresponding 95％ confidence interval (CI).Results The final analysis included seven trials comprising 1889 patients.Biochemical failure in 3months (RR0.73,95％ CI 0.55-0.96;P =0.02),1 year(RR 0.69,95％ CI 0.58-0.80;P ＜ 0.01) and 2 years (RR 0.58,95％ CI 0.41-0.82;P =0.002) were fewer in patients who received narrow band imagingassisted TURB.The recurrence rates of 3 months,1 year and 2 years were 14.44％,29.35％ and 30％ in white light imaging group.The recurrence rates of 3 months,1 year and 2 years were 3.61％,9.35％ and 12.59％ lower in narrow band imaging group compared with white light imaging group.Conclusions Narrow band imaging-assisted TURB was superior to conventional white light imaging-assisted TURB in primary non-muscle-invasive bladder cancer in 2 years.

Aim To investigate the effects of mmLDL on the up-regulation ofα1 receptors in moues mesenter-
ic arteries. Methods Mice tail intravenous injection of mmLDL was used . Vitro sensitive myograph was empl-
oyed to examine Noradrenaline ( NA) induced vascular contraction on mice mesenteric artery, and the mRNA and protein expressions ofα1 andα2 receptors were an-alyzed by real-time PCR and Western blot, respective-ly. Results mmLDL significantly increased NA in-duced concentration-contractile curve, and the data of Emax and pEC50 were from ( 122. 61 ± 9. 40 )% and (5. 65 ± 0. 05 ) in normal saline ( NS ) group to (161. 01 ± 6. 90 )% and ( 6. 20 ± 0. 08 ) in mmLDL group (P <0. 01, P <0. 01), respectively. The α1 adrenoceptor antagonist prazosin shifted the concentra-
tion-contractile curve induced by NA towards right. Af-ter using mmLDL, the mRNA and protein levels of α1 adrenoceptor were significantly increased, but the mR-NA and protein levels of α2 adrenoceptor were not changed. Conclusion Tail intravenous injection of mmLDL enhances the vascular expressions of α1 adre-noceptors and the contractile effects mediated byα1 ad-renoceptors.
