Objective: To study the effect of antidepressant in treatment of patients with PSD (post-stroke depression) Method: 121 patients with PSD in their rehabilitation period were stratified by results of HAMD and then randomly divided into two groups, the study group (n=64) received Paroxetine 20 mg daily, the control group (n=57) received placebo After 4 months, the result was assessed with HAMD, CSS and ADL (activity of daily living) Result: In the period of rehabilitation of stroke, the degree of neurological impairment (CSS score) was positively correlated to depression (r=0 99, P

Objective To study the effect of transcranial ultrasound (US) on arterial recanalization in acute ischemic stroke patients.Methods Patients with acute middle cerebral artery (MCA) main stem occlusion after 6 h were randomized into a target group receiving low-frequency,pulse-wave mode,transcranial US for 30 min or a control group.All were treated with intravenous urokinase for thrombolysis.Transcranial doppler sonography (TCD) was used to document vascular occlusion and confirm recanalization at 2 h and 24 h after treatment,and the patients were evaluated using the National Institutes of Health Stroke Scale ( NIHSS).Results Recanilization (complete or partial) after 2 hours was significantly higher in the US group (44.4％) compared with the control group ( 10.5％ ).Recanalization had occurred in 50％ of the US group 24 hours after treatment compared with 15.7％ of the controls.At 2 h after treatment,33.3％ of the US group and 5.5％ of the controls had improved at least 4 points on the NIHSS assessment.After 24 hours the figures were 44.4％ and 10.5％.After 3 months,11 subjects from US group (61.1％ ) had a modified Rankin score ≤2 compared with 4 subjects (21％) from the control group.Conclusions In acute ischemic stroke,transcranial US has positive effects on recanalization and neural function.

Objective To analyze the application value of the rapid testing for influenza during 2007-2008 flu season at fever clinic in Beijing Chaoyang hospital Methods 500 patients with diagnosis of influenza-like illness were prospectively enrolled. Pharyngeal swabs were collected for influenza viral culture and rapid testing for influenza. Demographic characteristics, age, symptoms, lab tests, symptom recovery time and medical expense were also collected. The sensitivity, specificity, positive predictive value and negative predictive value for rapid testing were analyzed. Results A total of 500 patients were enrolled between Dec 2007 and March 2008. Among them 498 cases were used for analysis. Influenza B was most common by virus culture methed(n=208,41.8%) ,followed by influenza A (n=51,10.2%). The average age was 35, and the ratio of male to female was 1.47:1. Compared with the group of positive culture, patients with influenza were more likely to get cough, sore throat, and nasal congestion (t=13.728, 4.014and 4.720,P<0.001 or 0.05, respectively). A total of 260 cases were subjected to rapid testing, Among them 18 cases were influenza A positive and 132 cases were influenza B positive. The rapid testing had a sensitivity of 77.1 % and a specificity of 70.1%. The positive predictive value was 78.6% and the negative predictive value was 68.2%. The rapid testing had enhanced the proportion of anti-viral treatment from 0 to 26% and reduced the proportion of antibiotic use from 63.4% to 20. 7%. Conclusions Influenza B is the most predominant pathogen during 2007-2008 flu season among patients with influenza-like illness in Beijing. The rapid testing with high sensitivity and specificity provides guidance on clinical practice.

Objective　To investigate the clinical significance of P-gp and TGFβ1 in cerebrospinal fluid (CSF) of drug-resistant epilepsy.Methods　Thirty responsive epilepsy patients were selected as sensitive group,30 cases of drug-resistant epilepsy were drug-resistant group,20 healthy persons were selected as control group.The levels of P-gp and TGFβ1 in CSF of all subjects were measured by ELISA,and the results were compared between groups.The levels of P-gp and TGFβ1 in patients with different seizure types in drug-resistant group were compared at the same time.Results　P-gp and TGFβ1 in CSF of drug-resistant group were (21.5±3.1) ng/ml and (217.3±49.6) pg/ml respectively,which were significantly higher than that of sensitive group and control group (P<0.05).The levels of P-gp and TGFβ1 in CSF were no significantly different between sensitive group and control group (P>0.05).The levels of P-gp and TGFβ1 in CSF of drug-resistant epilepsy patients with different seizure types had no significant difference (P>0.05).Conclusion　The levels of P-gp and TGFβ1 in CCSF can be used as an important detection marker for drug-resistant epilepsy of different seizure types.
