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 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 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 investigate the social cognition and its correlation with social function for attenuated psychosis syndrome (APS). Methods From August, 2014 to December, 2015, 39 patients with APS were recruited as research group. Another 40 normal healthy persons with similar gender, ages, and education levels were selected as control group. The Faux Pas Recognition Test (FPR) and Yoni Task Test were used to evaluate the social cognition, and Social Disability Screening Schedule (SDSS) was used to evaluate the social function. The correlation between FPR, Yoni Task Test and SDSS in the research group was analyzed. Results In FPR test, the faux pas questions score, control questions score and total score of FPR were significantly lower in the research group than in the normal control group (t>2.378, P<0.01). In Yoni Task Test, the cognitive theory of mind total score (Cog), cognitive theory of mind first-level score (Cog1) and cog-nitive theory of mind second-level score (Cog2), and affective theory of mind total score (Aff), affective theory of mind first-level score (Aff1) and affective theory of mind second-level score (Aff2) were significantly lower in the research group than in the normal control group (t>2.341, P<0.01). There was no significant difference in control theory of mind total score (Phy), control theory of mind first-level score (Phy1) and control theory of mind second-level score (Phy2) between two groups (t<1.430, P>0.05). The SDSS total score was signifi-cantly higher in the research group than in the normal control group (t=13.032, P<0.001). In the research group, FPR's faux pas questions score and FPR's total score were negatively correlated with SDSS score (r>0.473, P<0.01); in Yoni task test, Cog's total score and factor scores, Aff's total score and factor scores were negatively correlated with SDSS score (r>0.448, P<0.01). Conclusion Social cognition func-tion in APS is impaired. It is associated with social dysfunction in APS.

Objective To study the inhibition of berberine on organ anion transporters (OATs) and its bidirectional trans-membrane transport.Method The transgene cell lines of the organ anion transporters including OAT1,OAT2,OAT3,OAT4,OAT7,and URAT1 were constructed and selected by animal cell transgenic method mediated by transporter Lipo 3000.Wild type (WT) cells were used as control group,and activity of OATs was verified by adding their radiolabeled substrates and inhibitors.The inhibition of 100 μmol/L berberine on the transporters was investigated in vitro.The IC50 of berberine on URAT1 was also determined.The bidirectional transport of berberine was studied through the Caco-2 model.Result The results showed that 100 μmol/L berberine inhibited the activity of OAT1,OAT2,OAT3,OAT4,OAT7 and URAT1 to (70.48±4.23)%,(69.13±1.28)%,(72.12±3.28)%,(79.77±6.49)%,(69.51 ±5.99)% and (38.4 ± 2.67)% respectively,the IC50 of berberine to URAT 1 was 13.19 μmol/L,the Papp (A-B) of 50 μmol/L and 100 μmol/L berberine were separately 0.28 × 10-6 and 0.40 × 10-6 cm/s,and the effiux rates were separately 3.18 and 3.15.Conclusion Berberine shows a stronger inhibition to URAT1 compared to OAT1,OAT2,OAT3,OAT4 and OAT7.Berberine may be the substrate of some effiux transporters.This study provides theoretical basis for explaining the low bioavailability ofberberine and forecasting the possible drug-drug interaction.
