Objective To investigate the characteristics of the cognitive impairment about attentional network among amphetamine-induced psychiatric disorders. Methods Amphetamine-induced psychiatric disorders ( n = 100) and normal controls ( n = 100) were assessed with Attentional Network Test(ANT) in the first week and the fourth week. Results Compared with the control group, the first ANT's response time was significantly increased, and the correct rate, orienting and executive control network were significantly reduced in Amphetamineinduced psychiatric disorders( eg:response time ( 867. 37 ± 272.24 ) ms vs ( 668.56 ± 136. 20 ) ms, correct rate (0.88 ±0.06 ) ms vs (0.88 ±0.06) ms ,orienting( - 217.86 ± 198.00 ) ms vs ( -59.67 ± 85.07 ) ms and executive control network ( 184.74 ± 66.61 ) ms vs ( 74.71 ± 50.77 ) ms, P ＜ 0.01 ), but the alerting network was higher ( ( 151.17 ± 198.27 ) ms vs (50.60 ± 67.47 ) ms). In the second ANT results, there was no significant difference between two groups. Compared with the first ANT results of amphetamine-induced psychiatric disorders, the second ANT had shorten response time ,that the correct rate, orienting and executive control network were significantly increased(P ＜ 0.01 ). Conclusion These results suggest that amphetamine-induced psychiatric disorders have impairment in cognitive function, but these impairment can be recovered within one month.

Oxidation method with sodium iodide was used to synthesize immunogenic antigen (PF-BSA) and coating antigen (PF-OVA) of paeoniflorin. UV spectroscopy showed that paeoniflorin was successfully conjugated with BSA and OVA. After immunized by PF-BSA, the mice can produce anti-paeoniflorin antibodies specifically. The ELISA test results showed the high titer (1:12 800) and specificity (IC50 = 0.791 mg x L(-1)) of the antiserum from mice injected with PF-BSA. Also, the antiserum showed low cross activities against nine traditional Chinese medicine (TCM) of small molecules. These artificial antigens were successfully synthesized and the anti-paeoniflorin antibody well prepared, which provides the experimental basis for the further study of ELISA and its kit.

Objective To approach potential abnormalities of neuro-chemical compounds in cerebrum of obsessive-compulsive disorder and to analyze the relationship among the abnormalities with duration of illness and symptom severity. Methods 19 patients with obsessive-compulsive disorder and 22 comparison subjects were scanned by 1H magnetic resonance spectroscopy to exam bilateral prefrontal lobe, temporal lobe, parietal lobe, occipital lobe, anterior cingutate and caudate nucleus, hippocampus as well as splenium and genu of corpus callosum,thalamus. The ratios of N-acetylaspartate (NAA) and choline (Cho) to creatine (Cr) were respectively recorded.The severities of obsessive-compulsive symptoms were assessed by Yale-Brown Obsessive-Compulsive Scale. Results ( 1 ) The ratios of NAA/Cr in right caudate nucleus and left hippocampus were higher than those in normal controls (1.23 ±0.37 vs 1.0 ±0.33, t=2.14, P=0.039;1.34 ±0.25 vs 1. 10 ±0.45, t=2.41, P=0.021 ), but NAA/Cr ratios in genu of corpus callosum were lower(0. 97 ±0.30 vs 1.19 ± 0. 26, t = -2.47, P= 0.018 ).(2) The Cho/Cr ratios in right caudate nucleus and left temporal lobe were higher than those in control groups (1.09±0.51 vs0. 67±0.21,t=3.32, P=0.003;2.58±0.62vs0.84±0.17, t=2.21,P=0.03). (3) The duration of illness was negatively correlated with the Cho/Cr ratios of right prefrontal lobe ( r = - 0. 507, P =0. 027 ). (4) The NAA/Cr ratios of genu of corpus callosum as well as the Cho/Cr ratios of left temporal lobe were negatively correlated with YBOCS score ( r 1 = - 0.457, P = 0.049; r 2 = - 0. 585, P = 0.009 ). Conclusion Neuronal functions increase in right caudate nucleus and left hippocampus which are opposite in genu of corpus callosum. These abnormalities may play an important role in pathogenesis of OCD.

Objective To explore the impulsivity and aggressivity,and its treatment outcomes of the inpatients with intemet addiction disorder (IAD) by intergration interview. Methods Barratt Impulsiveness Scale ( BIS), Buss Aggressive Scale (BAS) were used to assess the impulsiveness and aggressivity in 58 IAD patients, at the first week and after the point of intergration interview 3 months,54 normal subjects in the control group were conducted by BIS and BAS only when they were recruited. Results ①The intemet addiction group had significantly higher scores on the BIS and BAS total scores than the control group at the first week ( BIS score 99.3 ±15. 1vs 75.0 ± 15.4, t=8.47, P＜0. 01; BAS score 78.3 ±24.4 vs 54.8 ± 17.7, t=5.87 , P＜0. 01 ). IAD group had lower scores on the total scores of BIS-Ⅱ and BAS after intergration interview than before, but the subscales and total scores were higher than those in the control group ( BIS score 86.3 ± 16.6 vs 75.0 ± 15.4, t =4.98, P ＜ 0.01 ;BAS score 66.2 ± 22.6 vs 54.8 ± 17.7, t = 3.65, P ＜ 0. 01 ). ②Total score of SCL-90 in IAD group were significantly correlated with the BAS total score ( r=0. 376, P＜0. 01 ) ,and the decreased SCL-90 total score was also related with the decreased BAS score ( r= 0.508, P＜ 0. 01 ). Conclusion This study suggests that IAD group exhibit more impulsivity and aggressivity than those in the control group. After interview, their impulsivity and aggressivity are significantly decreased, but are still higher than those in the normal control group.

The cyclodialysis cleft is a rare disease characterized by ocular hypotony and vision loss.Gonioscopy,ultrasound biomicroscopy and anterior segment optical coherence tomography are used to evaluate the cleft before treatment.The evaluation of cyclodialysis clefts provide a basis for the selection of treatment and the evaluation of effect.Current popular therapeutic approaches for cyclodialysis clefts include medical management,laser photocoagulation,transscleral diathermy,cryotherapy,cyclopexy and so on.Medical treatment is effective in small-size cyclodialysis cleft.But the indications and course of medical treatment remains controversial.Although laser photocoagulation,transscleral diathermy and cryotherapy are effective to treat cyclodialysis clefts in some cases,there are some risks,such as ocular damage,uncertainty about the effect and so on.Cyclopexy is the principal method for cyclodialysis clefts that failed to respond to conservative management,including extraocular cyclopexy,intraocular cyclopexy and cyclopexy under endoscopic.The modified cyclopexy is effective which reduces the surgical risk.For keeping the lens,intraocular cyclopexy and cyclopexy under endoscopic are not suitable.Vitrectomy combined with other method for cyclodialysis is effective for cyclodialysis clefts which combined with serious posterior segment damage.

Objective To study the levels of senlm uric acid(UA)in normal glucose(NC),impaired glucose regulation(IGR)and type 2 diabetes mellitus(T2DM),and investigate its relationship with insulin resistance and dyslipidemia.Method The levels of blood glucose,lipids,fasting insulin(HNS)and serum UA were measured in patients of 45 T2DM(T2DM group),20 IGR(IGR group)and 29 NC(NC group).Status of insulin resistance and insulin secretion function was evaluated by HOMA-IR and ISI.Results The levels of triglyceride(TG)and UA in T2DM group and IGR group were significantly higher than those in NC group[(3.34±8.77),(1.85±0.67),(1.26±0.38)mmoi/L and(316.71±96.20),(403.62±76.80),(325.45±94.43)mmol/L](P<0.01).HDL-C levels in T2DM group were significantly lower than those in IGR and NC group[(1.05±0.30),(1.07±0.21),(1.12±0.20)mmol/L](P<0.01).NO significant difference of FINS levels was found in the three groups.HOMA-IR level in T2DM and IGR group was higher than that in NC group(3.84,3.77,2.34)(P<0.01).ISI in T2DM and IGR group was lower than that in NC group(-4.52±0.79,-4.44±0.19,-4.03±0.58)(P<0.01).Correlation analysis indicated that the level of UA was positively related with BMI.TG and negatively related with HDL-C.Conclusion Increased UA in IGR indicates that hyperurieacidemia developes before DM.
