OBJECTIVE:To systematically review the effectiveness and safety of olanzapine in the prevention and treatment of chemotherapy-induced nausea and vomiting(CINV),and provide evidence-based reference for clinical treatment. METHODS:Re-trieved from Medline,PubMed,EMBase,Cochrane Library,Clinical Trials.gov,CBM,CJFD,VIP and Wanfang Database,ran-domized controlled trials (RCT) about olanzapine (test group) versus other drugs or conventional antiemetic regimen (control group)in the prevention and treatment of CINV were collected,Meta-analysis was performed by using Rev Man 5.3 software after data extraction and quality evaluation by modified Jadad. RESULTS:Totally 19 RCTs were included,involving 1 794 patients. Re-sults of Meta-analysis showed,olanzapine can significantly improve the complete control rate of patients with acute CINV [RR=1.12,95%CI(1.06,1.18),P<0.001],delayed CINV[RR=1.26,95%CI(1.14,1.39),P<0.001],overall CINV [RR=1.62,95%CI (1.32,1.99),P<0.001] and breakthrough CINV[RR=2.05,95%CI(1.47,2.86),P<0.001],there were significant differences be-tween 2 groups;there were no significant differences in the incidence of tiredness,dizziness,lethargy and constipation(P>0.05). CONCLUSIONS:Olanzapine is safe and effective in the prevention and treatment of CINV and can be recommended in treating breakthrough and refractory CINV. Besides,olanzapine in the prevention and treatment of CINV belongs to“off-label use”,so the clinicians should have a comprehensive consideration of chemotherapy and patients’consent.

Objective To study the therapeutic effect and safety of acupuncture a long with the deep respiration on patient of acute traumat ic laryngitis. Methods Totally 240 cases with wind heat syndrome were divided into a treatment group (treated by puncturing acupoint Ka iyin 1 as the main point in combination with deep respiration of the patient) and a control group (treated by gentamy cin sulfate and dexamethasone spray-inhalation). After the treatment for 5 days , both groups were observed on the changes of the symptom scores for congest i on and swelling of vocal cords, sore throat, and hoarseness for evaluating the t herapeutic effect and safety. Results On the 3rd day of treatment, the cured and markedly effective rate of the treatment group was sig nificantly higher than that of the control group (P0.05). There was no untowards finding in l aboratory test. Conclusion Puncturing acupoint Kaiyin 1 as the main point in combination with deep respiration of the patient is a effe ctive and safe treatment for acute traumatic laryngitis.
