Objective To compare the efficacy of amisulpride and other SGAs in treating the negative symptoms of Schizophrenia.Methods The randomized controlled trials (RCTs) about Schizophrenia treated with amisulpride and other SGAs from Jan 1995 to Mar 2013 were searched in The Pubmed,EMbase,Cochrane Library,WanFang Data,CNKI and VIP.Two reviewers independently screened the literatures,extracted the data,and evaluated the methodological quality.Than meta-analyses were conducted by using RevMan 5.1 and Stata 12.0 software.Results The totall3 RCTs were included.Among the 1814 patients involved.The results of meta-analyses showed that the score of PANSS-N was no significant differences between two groups (MD =-0.33,95％ CI:(-0.87,0.21),Z =1.20,P =0.23) ; and the score of SANS was no significant differences between two groups (MD =-0.21,95％ CI:(-1.51,1.50),Z =0.31,P =0.76).The side effects were more in other SGAs group than those in amisulpride group.Conclusion Amisulpride is as effective as other SGAs for the treatment of schizophrenia with predominantly negative symptoms,and it has more advantage than other SGAs in safety.

Objective To evaluate the effect of theta burst stimulation( TBS) paradigm of repetitive tran?scranial magnetic stimulation ( rTMS ) on the treatment of schizophrenia through assessing executive function. Methods 60 patients met with DSM?4 and ICD?10 for schizophrenia disorders criteria were enrolled in this study. The group was divided into theta burst stimulation group(research group, n=30) and sham intervention group ( control group, n=30) . The research group and control group were assessed with the Wisconsin card sorting test (WCST) and the go/no?go task by event?related potential(ERPs) before and after 4 weeks treatment. Each test results of all groups before and after treatment were compared with each other respectively. Results Regarding the WCST test,compared with the baseline,the post?rTMS state of the TBS group showed a decrease in the error selec?tion percentage((59.8±14.7)%),the preservative error number(55.3±18.0) and the preservative error percentage (71.3±12.6)%,but the percentage of conceptual level(71.3±12.6)% increased in the TBS group(P<0.05). Re?garding the go/no?go task by ERPs,compared with the baseline,the post?rTMS statet of the TBS group showed an increase in the no?go P3 amplitude(P<0.05 or 0.01) . After intervention,the score of WCST test and the no?go P3 amplitude were significant differences in TBS group compared with same rTMS group(P>0.05).Conclusions The?ta burst stimulation paradigm of rTMS can improve the executive function in schizophrenic patients.

Objective To assess whether topiramate prevents body weight gain in patients with olanzapine .Methods The ran‐domized controlled trials(RCTs) about topiramate for prevention of weight gain with olanzapine from 1998 to 2013 were searched in the Cochrane Library ,Pubmed ,EMbase ,WanFang Data ,CNKI and VIP .Two reviewers independently screened the literatures ,ex‐tracted the data ,and evaluated the methodological quality .Then Meta‐analyses were conducted by using RevMan 5 .1 software .Re‐sults The total of 11 RCTs were included .Among the 549 patients were involved .The results of Meta‐analyses showed that the ef‐ficacy of the topiramate group was superior to that of the control group in lessen body mass with significant difference (MD= -3 .68 ,95% CI:-5 .16- -2 .19 ,Z=4 .86 ,P<0 .01) .Conclusion Topiramate addition therapy is effective in attenuating olanzapine‐induced weight gain .

Objective To explore the effect of theta burst stimulation (TBS) paradigm of repetitive transcranial magnetic stimulation (rT-MS) on executive function in patients with chronic schizophrenia. Methods 60 patients meeting DSM-IV for chronic schizophrenia disor-ders criteria were enrolled. They were randomly divided into TBS group (n=30) and sham intervention group (n=30). They were assessed with digit span performance, space span performance and Wisconsin Card Sorting Test (WCST) before and 4 weeks after intervention. Re-sults After intervention, the forward score of digit span performance, the total score and forward score of space span performance increased (P<0.05), the error selection percentage, the error selection number and the percentage of error number of WCST decreased, the percentage of conceptual level of WCST increased (P<0.05) in the TBS group. However, there was no significant difference in the digit span perfor-mance, space span performance and WSCT in the sham intervention group (P>0.05). There was significant difference in all the items be-tween 2 groups after intervention (P<0.05). Conclusion TBS paradigm of rTMS could improve the executive function in schizophrenic pa-tients.

Objective To determine the frequency of Toll-like receptor 4 (TLR4)polymorphisms Asp299Gly and Thr399Ile in a cohort of hematopoietic stem cell transplant recipients and their donors in China.Method We examined the polymorphisms in 208 peripheral blood samples collected from 104 recipients and their donors in a single center between 2007-2012 in Zhejiang Province,China,and Asp299Gly and Thr399Ile TLR4 gene polymorphisms were detected using the sample DNA amplification products direct sequencing and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.Result Both methods didn't demonstrate TLR4 polymorphisms Asp299Gly or Thr399Ile base mutation in our samples.Conclusion The TLR4 Asp299Gly and Thr399Ile polymorphisms are very rare in our part of the population of hematopoietic stem cell transplantation.

Objective To investigate the possible protective effect of adenoviral vector expressing interleukin-1β (IL-1β) small hairpin RNA (shRNA) on spinal cord injury (SCI) and its mechanism in rats.Methods Forty-eight adult male Sprague-Dawley rats were randomly assigned to 4 groups including the Sham, the Vehicle,the Ad-GFP and the Ad-shIL-1β groups.SCI was induced by epidural compression.Motor function of hind limbs was evaluated by Basso-Beattie-Bresnahan (BBB) score, the expressions of green fluorescence in injured spinal cord tissue were observed by fluorescence microscope.Enzyme-linked immunosorbent assay (ELISA) and immunofluorescence were also performed.Results The expressions of green fluorescence in injured spinal cord tissue were observed in the Ad-GFP and Ad-shIL-1β groups one day after SCI.Significant functional improvement was observed in the Ad-shIL-1β group (8.17 ± 1.17, 10.17 ± 0.98 and 11.33 ± 0.82, respectively) compared to the Vehicle (4.00 ± 0.89, 5.67 ± 1.03 and 6.17 ± 1.17, respectively) and Ad-GFP (3.83 ± 0.98, 5.33 ± 1.21 and 5.67 ± 1.03, respectively) groups at 7, 14 and 21 days after SCI (P ＜ 0.05).Rats in the Ad-shIL-1β group had less neuronal loss 21 days after SCI.In addition, IL-1β downregulation significantly decreased IL-1β, tumor necrosis factor-or (TNF-α) and IL-6 levels (138.83 ± 7.96,143.38 ± 10.20 and 120.43 ± 9.79 in Ad-shIL-1β group;169.33 ± 11.45, 172.33 ± 8.26 and 163.00 ± 9.57 in Vehicle group;172.83 ± 10.85,167.48 ± 8.19 and 159.48 ± 10.98 in Ad-GFP group, respectively) one day after SCI (P ＜ 0.05).Conclusion This study demonstrated that the IL-1β downregulation may have potential therapeutic benefits for improving the outcomes after SCI.

Organ transplant has become one of the strategies for treatment of malignant disease. The transplant-related complications restricted the further development of organ transplantation; graft rejection is most prominent among these complications, which remains a major cause of morbidity and mortality after organ transplant. Toll like receptors 4 (TLR-4) has been shown as a key molecule in innate immunity and immune tolerance. The role of TLR4 in graft rejection after organ transplant is still unknown. This article will review the role and the mechanism of TLR4 to control APC mature, activate T cells, trigger immune attack to organ graft; therefore bring new insights into the pathophysiology of graft rejection and foster the development of new therapies to control graft rejection after organ transplant.
