Objective To evaluate efficacy and safety of escitalopram in treating depression .Methods In this randomized , single-blind, citalopram parallel controlled, fixed dosage study, the study group was treated with escitalopram tablet 10mg/d and the control group with citalopram tablet 20mg/d.Observation duration was 6 weeks.Hamilton Rating Scale for Depression ( 17-item HAMD),Clinical Global Impression (CGI) and Hamilton Rating Scale for Anxiety (HAMA) were used to measure the efficacy.Items including Treatment Emergent Symptoms Scale (TESS), lab examination and vital signs for assessment of safety .Results Eighty-eight patients were randomly divided into study group (43 patients) and control group (45 patients).After 6 weeks treatment, a signif-icant greater reduction in HAMD 17 ,CGI-SI and HAMA total score was found for both study group and control group showing significant difference with their baseline ( P <0.01 );but there were no significant difference between two groups ( P >0.05 ) .However , after 1 week treatment , the HAMD17 and CGI-SI score reductions between two groups were significant difference ( P <0.01 ) .The score of HAMA was no significant difference between two groups ( P >0.05 ) .In study group , the positive response rates was 81.4%,and in controls was 80.8%, there was no significant difference between two groups ( P >0.05 ) .There was no significant difference about the incidence of adverse reaction between two groups ( P >0.05 ) .Conclusions Escitalopram is a safe and effective antidepressant as citalopram , however , it has a more rapid reaction than the latter .

Objective To assess the efficacy of combining vestibular rehabilitation with cognitive behavioral therapy in treating chronic subjective dizziness ( CSD) and the associated anxiety. Methods A total of 98 anxious CSD patients were randomly divided into an experimental group ( n=50) and a control group ( n=48) . All of the pa-tients′scores on the Hamilton anxiety scale ( HAMA) were no less than 14 and their scores on the Hamilton depres-sion scale ( HAMD) were less than 18. Systematic vestibular rehabilitation was given to the patients in the control group, while this was combined with cognitive behavioral therapy for the patients in the experimental group. All pa-tients were evaluated using a dizziness handicap inventory ( DHI) and the HAMA before treatment and in the 4th and 8th week of the treatment. Results Before the treatment there was no significant difference between the 2 groups in any of the assessments. After 3 weeks of treatment, the average HAMA score, DHI total score and its factor scores had decreased significantly. Four weeks later, the average HAMA score, DHI total score and its factor scores for som-atization, emotion and function had improved significantly in both groups compared with before treatment and the scores after 3 weeks. After 3 and 7 weeks of treatment, the average HAMA score, DHI total score and its factor scores of the experimental group were significantly lower than those of the control group. Conclusion Cognitive behavioral therapy amplifies the effects of vestibular rehabilitation in treating persons with CSD, in part by significantly relieving their anxiety.

Objective: To explore the relationship between the expressions of chemokine receptor CXCR4 and vascular endothelial growth factor C (VEGF-C ) with lymph node metastasis in human rectal cancer. Methods: Immuohistochemical staining was used to detect the expressions of CXCR4 and VEGF-C in 73 samples of human rectal cancer. The relationship between CXCR4 and VEGF-C in 73 samples of human rectal cancer. The relationship between CXCR4 and VEGF-C expressions was analyzed. Results: The positive rate of CXCR4 expression with lymph node metastasis was higher than that without lymph node metastasis (60.1% vs 23.3%,P
