Objective: To observe the clinical effect of escitalopram in the treatment of alcohol-dependent patients with depressive symptoms and its influence on social function recovery. Methods: From January 2016 to December 2017, 80 alcohol-dependent patients with depressive symptoms in the Seventh People's Hospital of Wenzhou were selected and divided into two groups by random digital table method, with 40 cases in each group.The observation group was treated with escitalopram.The control group was treated with placebo for 2 months.The scores of depression, social dysfunction screening scale, quality of life and incidence of adverse reactions were compared between the two groups. Results: After treatment for 1 month and 2 months, the depression scores of the observation group were (15.02±2.23)points and (9.02±2.12)points, respectively, which were lower than those of the control group[(20.13±2.12)points, (15.24±2.15)points](t=10.504, 13.029, all P<0.05). After treatment for 1 month and 2 months, the scores of the screening scale for social functional defects in the observation group were (2.85±1.23)points and (0.89±0.52)points, respectively, which were lower than those in the control group[(4.13±1.62)points, (2.52±1.16)points](t=3.930, 8.110, all P<0.05). The scores of physical health, mental health, physical life, social function and total quality of life in the observation group were (87.47±5.69)points, (84.63±5.21)points, (87.16±5.24)points, (85.46±5.95)points and (86.12±5.95)points, respectively, which were higher than those of the control group[(79.58±5.93)points, (76.72±7.82)points, (79.28±5.57)points, (75.92±5.45)points, (78.46±5.85)points](t=5.995, 5.257, 6.435, 7.384, 5.733, all P<0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups(P>0.05). Conclusion Escitalopram in the treatment of alcohol-dependent patients with depressive symptoms has good effect, not only helps to improve the depression, but also helps to promote the recovery of social function of the patients, and the safety is relatively high.

Objective To investigate the changes of event-related potentials (ERPs) in patients with intelligence impairments after craniocerebral trauma.Methods 60 patients with intelligence impairments after craniocerebral trauma were enrolled as case group,and 60 healthy subjects were enrolled as control group.EEG instrument was used to record P300 and P50 of the two groups and the differences in P300 and P50 components were compared.Results There are significant differences between case group and control group in latency of P300 ((440.430 ± 77.367) ms vs (342.928 ± 36.175) ms,P＜ 0.01),and case group showed decreased amplitude ((12.692±8.152) μV vs (18.138±6.590) μV,P＜0.01).The S2-P50 amplitude of case group was significantly higher than that of control group ((3.75± 1.59) μV vs (2.42±1.43) μV,P＜0.01).In addition,the S2-P50 amplitude/S1-P50 amplitude ratio of case group was higher than that of the control group,and the difference was statistically significant (0.78±0.54 vs 0.46±0.18,P＜0.01).The latency and amplitude of P300 were significantly correlated with the total score of WAIS-RC (r=-0.31,P＜0.01;r=0.17,P＜0.01);The amplitude of S2-P50 and the ratio of S2-P50 amplitude to S1-P50 amplitude were significantly negatively correlated with the total score of WAIS-RC (r=-0.33,P＜0.01;r=-0.45,P＜0.01).Conclusion P300 and P50 components of ERP can provide references for judicial expertise to evaluate intelligence impairments after craniocerebral trauma.
