Objective To explore the brain electrophysiological mechanism of object rotation in first-episode schizophrenia.Methods 30 patients with schizophrenia and 28 normal healthy people,who were from the Center for Mental Disease Control and Prevention,Third Hospital of PLA,took part in the mental rotation tasks,then the incubation period and amplitude of P500,and the wrong number and reaction time were measured.Results Compared with control group ( normal:(494.16 ± 34.68 ) ms,( 9.56 ± 2.54) μV; mirror:(496.51 ± 33.10 ) ms,(6.38 ± 2.41 ) μV),schizophrenia' incubation periods were significantly delayed ( normal:( 571.30 ± 51.21 ) ms;mirror:(573.41 ±39.27) ms) and volatility were significantly lower ( normal:(4.26 ± 1.01 ) μV; mirror:(3.61± 1.21 )μV) in normal and mirror rotation (P＜0.05 ).The mirror-normal differences were not significant on the incubation periods of two groups (P ＞ 0.05 ) ; the mirror-normal image differences were not significant on the patient group' volatility (P ＞ 0.05 ) ; the normal volatility was significantly higher than mirror in the control group (P ＜ 0.05).Conclusion Schizophrenia'mental rotation ability is impaired,and mirror-normal differences on mental rotation are disappeared.It can be used as an early-stage clinical auxiliary diagnosis index.

AIM: To probe into the anti-epilepsy action of artificial Calculus Bovis,by observing its effect on the behavioral of the experimental epileptic rats,neuron loss in the hippocampus and hilus,and GAD positive cell alteration in the hippocampus.METHODS: SD rats were divided into three groups: group A(artificial Calculus Bovis treatment group);group B(acute epilepsy group) and group C(control group).A model of acute epilepsy rats was established by PTZ.The rat's behavioral alteration was observed by the Racine' scale.The neurons in the hippocampus and hilus were calculated by Nissl staining.The GAD positive cells were observed by immunohistochemical staining.RESULTS: The latency of the first seizure in group A was longer than that in group B,while the seizure times in group A was less than that in group B.Besides,in group A,both the neuron loss amount in the hippocampus and hilus and the GAD positive cell loss amount in the hippocampus were less than those in group B.CONCLUSION: The artificial Calculus Bovis prolonged the latency of the first seizure time,decreased the frequency of seizure,and prevented the neuron loss and protected the GAD positive cells.

Objective To develop the optimal simplified combination of joints for ultrasonographic assessment of joint inflammation of wrists and hands in patients with rheumatoid arthritis (RA).Methods US examination was performed using grey-scale (GSUS) and power Dop.pler (PDUS) semi-quantitative scoring systems with scores 0-3 in 22 joints of 705 RA patients,including all proximal interphalangeal (PIP),metacarpophalangeal (MCP),and bilateral wrist joints.Continuous variables were presented as mean and standard deviation if normally distributed,and dichotomous variables were presented as frequencies.T test and Wilcoxon signed test were applied for statistical analysis.All correlations among US variables were assessed using Spearman's rank correlation test.Candidate joint set was selected by multiple stepwise linear regression analysis.Results Through multiple linear stepwise regression analysis,the standard coefficient of wrist,MCP5,MCP2 and MCP3 joints under GSUS was higher than other joints.And the adjusted R2 of the model composed of wrist,MCP5,MCP2 and MCP3 joints was greater than 0.9.Among the sum GS and PD scores of various selected joint combinations,total score-8 (GS vs PD),including bilateral wrist,MCP2,MCP3,MCP5 joints,not only showed highest sensitivity and negative predictive value (97.3 5％ vs 97.20％;92.67％ vs 97.21％,respectively),but also had the highest correlation with the total score-22 (GS,PD) (r=0.989,0.972,P＜0.01).Conclusion Total score-8,including bilateral wrist,MCP2,MCP3,MCP5 joints,is simple and efficient enough for monitoring active synovitis of wrists and hands in patients with RA in daily practice.

Objective: To investigate the efficacy and safety of micafungin (MCF) for pulmonary invasive fungal disease (PIFD) in pediatric patients with acute leukemia or post hematopoietic stem cells transplantation. Method: Twenty-five neutropenic PIFD children with acute leukemia or post hematopoietic stem cells transplantation in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were selected from January 2012 to June 2015, including 12 males and 13 females, age range 2-15 (average 6.2±2.0) years. There were 12 cases of acute leukemia (AL) after chemotherapy, 4 cases of acute leukemia (AL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and 9 cases of β-thalassemia major after allo-HSCT. All children received MCM for the treatment of PIFD, the dosage of MCM was 3-4 mg/ (kg·d) , once a day. The children received 2 to 6 courses of treatment, individually with a course of 7 days. 1, 3-β-D glucan assay (G test), galactomannan antigen test (GM test), high-resolution CT and the biochemical indexes for organ functions were closely monitored. Result: Twenty-five cases were diagnosed as PIFD, including 2 patients diagnosed as proven, 6 as probable and 17 as possible. Of the 25 cases, 1 was confirmed aspergillus by biopsy pathology and 1 was candida albicans by blood culture. The G and GM test with positive results was 5 and 2 respectively. Chest CT scans of the 25 cases had obvious lesions: air crescent sign and cavitation in 4 cases, diffuse ground glass change in 9 cases, double lung scattered patchy, small nodules and cord like high density shadow in 7 cases, unilateral or bilateral chest wall wedge-shaped consolidation edge in 5 cases and pleural effusion in 5 patients. The effective rate of MCF in treatment of PIFD was 68% (17/25), including 13 cases cured, 4 cases improved, 4 cases were improved clinically and in 4 cases the treatment was ineffective. Eight cases were effective in MCF monotherapy group (12 cases) and nine were effective in MCF combined therapy group(13 cases), respectively. Side-effects including allergies, gastrointestinal side effects, electrolyte disturbances, impairment of liver and kidney function, and myelosuppression were not found in those children treated with MCF. Conclusion Micafungin is effective and safe in the treatment of pulmonary invasive fungal disease in pediatric patients with acute leukemia or post hematopoietic stem cell transplantation.
