Objective To explore the effect of amisulpride and risperidone in the treatment of patients with first-episode schizophrenia and its influence on social function.Methods 70 patients of schizophrenia conformed to the International classification of diseases tenth edition(ICD-10) were randomly divided into amisulpride group(observation group,35 cases) and risperidone group(control group,35 cases) by using the random number table method.The Positive and Negative Scale(PANSS) was used to evaluate the efficacy,the Scale of Social Function in Psychosis Inpatients(SSPI) was used to evaluate social function before and after 8 weeks of treatment.Results After 8 weeks treatment,the negative symptom factor score of the PANSS in the observation group was (15.04±3.55)points,which was improved significantly compared with (17.82±3.87)points in the control group,the difference was statistically significant(t=3.132,P<0.05).The scores of the field in movement and interaction,social activities and skills factor score and the total score of SSPI in the observation group were (15.49±3.54)points,(14.53±4.25)points,(39.25±8.27)points,respectively,which in the control group were (12.78±3.29)points,(10.01±3.78)points,(33.72±7.83)points,respectively,the differences between the two groups were statistically significant (t=3.317,4.701,2.873,all P<0.05).Conclusion Amisulpride is effective in improving the negative symptoms,social function in patients with schizophrenia,and the effect is better than risperidone.

Aim To establish depression rat model with kidney-yang deficiency and evaluate the related parameters.Methods A total of 24 adult SD rats were divided into control group,mod-el group and self-healing group by body weight.Model group and self-healing group were injected hydrocortisone for 21 days, meanwhile the control group was injected sodium chloride.After modeling,the related indexs detection were taken out:open-field test,sucrose preference test and forced swim test.Then the orbital blood was taken to detect 5-HT,DA and NE by LC-MS/MS.And liver,kidney,spleen,thymus,adrenal gland,testis and epididymis were taken to calculate organ index.Results Compared with the control group,model rats displayed depres-sion and kidney yang deficiency syndrome such as dry hairs, chills,back arched and so on. Correspondingly, the body weight increased slowly.Immobility in FST was significantly in-creased. Sucrose preference, horizontal scores and vertical scores was significantly decreased.Organ index decreased in liv-er,kidney,spleen,adrenal,testis and epididymis.The level of 5-HT and NE was significantly high.Compared with the model group,5-HT,NE and DA were significantly reduced,5-HT and DA were even lower than those of the control group.Conclusion Depression rat model with kidney-yang deficiency could be in-duced by continuous injection of hydrocortisone.
