OBJECTIVE:To observe therapeutic efficacy and safety of escitalopram and fluoxetine in the treatment of depres-sion. METHODS:106 patients with depression were randomly divided into observation group and control group with 53 cases in each group. Observation group was given escitalopram 10-20 mg,qd,and control group was given 20-40 mg,qd. Both groups were treated with 6 weeks. The levels of IL-2,IL-6,TNF-α and Hcy were observed in 2 groups,and HAMD and TESS were re-corded in 2 groups. RESULTS:Total effective rate of observation group (86.79%) was higher than that of control group (77.36%),with statistical significance(P>0.05);after treatment,the levels of IL-2,IL-6,TNF-α and Hcy decreased significant-ly in 2 groups,the observation group was lower than the control group,with statistical significance (P<0.05). After treatment, emotion,mental anxiety,sleep disorder,cognitive disorder,somatic anxiety score and HAMD total score all decreased significant-ly in 2 groups,the observation group was significantly lower than the control group,with statistical significance(P<0.05). TESS score of observation group was significantly lower than that of control group 3 weeks and 6 weeks after treatment,with statistical significance (P<0.05). CONCLUSIONS:Escitalopram is similar to fluoxetine in the treatment of depression,but escitalopram can improve inflammatory response significantly and decrease the level of Hcy with mild ADR.

Objective To evaluate the effect of near infrared heptamethine cyanine dye IR-783-mediated specific tumor imaging in spontaneous tumor of dogs .Methods IR-783 was intraperitoneally injected to nude mice models of transplanted tumor in a dose of 5μmol/kg.The metabolic time course of IR-783 was detected by in vivo imager .Based on the results of above observation , IR-783 was injected to dogs with spontaneous tumor in a dose of 1.5μmol/kg.The site of intravenous injection was the hind leg .Tumor and peri-tumoral tissues were removed at 5 days after IR-783-injection for fluorescence imaging , pathology and frozen section fluorescence examinations .Results After i.p.IR-783 injection to nude mice models of transplanted tumor , the transplanted tumor tissues of nude mice had stronger specific fluorescence than normal tissues by imaging at 8 days after injection .After i.v.IR-783 injection to four dogs with spontaneous tumor , the fluorescence signal in the tumor tissues was stronger than that in the normal tissues at 5 days after injection .Conclusions Near infrared fluorescent dye IR-783 could be specifically taken up by tumor tissues , and can be used for specific diagnosis of tumor.It has an important clinical application prospect .
