R software is a free and powerful statistical software, which has the functions of data processing and graphics drawing and is widely used in the meta-analysis. This article introduced detailed operation steps of rmeta package which is suitable for meta-analysis of binary data, and also can finish cumulative meta-analysis, draw standard summary plots, forest plot and funnel plot. In summary, the functions of rmeta package are simple and easy to mastery. There are some limitations of current version which need to be improved in the future.
ObjectiveTo systematically review the major risk factors of road traffic injuries, so as to provide scientific basis for road traffic injuries prevention strategies. MethodsSuch databases as PubMed, EMbase, The Cochrane Library, Springer, EBSCO, CBM, CNKI, VIP, and WanFang Data were searched from inception to March 31st, 2014, to collect case-control studies on the risk factors of motoring vehicle road traffic injuries. According to the inclusion and exclusion criteria, literature screening, data extraction, and methodological quality assessment were independently completed by two reviewers. Meta-analyses were performed using RevMan 5.2 software. ResultsEighteen studies involving 368 845 motor vehicle drivers who had traffic accidents and 411 147 motor vehicle drivers who had no traffic accident were included. The results of meta-analysis showed that, the risk factors mainly included carelessness (OR=19.95, 95%CI 6.42 to 62.03), drunk driving (OR=9.36, 95%CI 4.62 to 18.95), driving without licence (OR=5.07, 95%CI 1.93 to 13.31), illegal operation (OR=4.87, 95%CI 1.98 to 11.93), fatigue driving (OR=4.08, 95%CI 3.21 to 5.18), and lack of driving experience (OR=3.81, 95%CI 2.08 to 6.97). ConclusionCarelessness, drunk driving, driving without licence, illegal operation, fatigue driving, and lack of driving experience are major risk factors of motor vehicle road traffic injuries in China. Controlling these risk factors can effectively reduce the incidence of motor vehicle road traffic injuries.
ObjectiveTo investigate strategies and efficacy of surgical treatment of advanced hepatic alveolar echinococcosis. MethodsThirty-six patients with advanced hepatic alveolar echinococcosis who underwent surgical treatment in our hospital from August 2014 to March 2016 were selected, who were divided into three groups:radical hepatectomy group (15 cases), quasi-radical hepatectomy group (17 cases), and palliative surgery group (4 cases). The operative time, intraoperative blood loss, postoperative complications, and metastasis were analyzed among these three groups. ResultsThe operative time, intraoperative blood loss, and rate of postoperative complications had no significant differences between the radical hepatectomy group and the quasi-radical hepatectomy group. No patient had postoperative recurrence in the radical hepatectomy group. The hepatic portal residual lesion was enlarged for 1 case and the intrahepatic and extrahepatic lesions were stable for the other patients in the quasi-radical hepatectomy group. In the palliative surgery group,the retroperitoneal lesions enlargement was seen in 2 cases and the lesions around the abcess grew progressively in 1 case. ConclusionIndividualized treatment accompanied with multiple-disciplinary treatment and damage-control surgery concept could benefit optimally to patients with advanced hepatic alveolar echinococcosis.
