Objective To systematically assess the clinical efficacy and safety of cilostazol for preventing ischemic stroke recurrence. Methods Such databases as PubMed, The Cochrane Library, EMbase, CNKI, CBM, and VIP were searched for randomized controlled trials (RCTs) on the use of cilostazol to prevent ischemic stroke recurrence (up to November, 2010). Two researchers selected studies and extracted data independently using a designed extraction form. The quality of included trials was evaluated and RevMan 5.0 software was used for meta-analyses. Results Four RCTs involving 3 916 patients were included. The results of meta-analyses showed that there were significant differences between cilostazol and aspirin in terms of hemorrhagic stroke occurrence (RR=0.39, 95%CI 0.24 to 0.61, Plt;0.000 1), headache occurrence (RR=1.99, 95%CI 1.16 to 3.43, P=0.01) and dizziness occurrence (RR=1.43, 95%CI 1.13 to 1.79, P=0.002). Whereas, no significant difference was found between the two groups in terms of ischemic stroke recurrence (RR=0.80, 95%CI 0.61 to 1.04, P=0.10) and transient ischemic attack occurrence (RR=0.93, 95%CI 0.45 to 1.92, P=0.85). Conclusion The current evidence indicates that cilostazol is as effective as aspirin in preventing ischemic stroke recurrence, but with less incidence of hemorrhagic stroke.
Objectives To assess the efficacy and safety of cytidine diphosphate choline for patients with acute stroke. Methods Such databases as PubMed, The Cochrane Library, EMbase, Web of Science, CNKI, VIP Database and Chinese Medical Association Journals were searched from the establishment to September of 2010, and the references of the included literatures were also searched to collect randomized controlled trials (RCTs) of cytidine diphosphate choline for patients with acute stroke. The data were extracted by two reviewers independently in accordance with the inclusion criteria. The quality of included trials was evaluated according to the Jadad scale standard. RevMan5.0 software was used for data analyses. Results Thirteen RCTs involving 2837 patients were included. The results of meta-analyses showed that, there was no significant difference in the mortality or the rate of dependency at the end of follow-up (OR=0.94, 95%CI 0.66 to 1.36, P=0.75) between the cytidine diphosphate choline group and the placebo group. But the total effective rate of the cytidine diphosphate choline group was higher than that of the placebo group with a significant difference (OR=1.72, 95%CI 1.41 to 2.10, Plt;0.000 01). Five trials reported the incidence of adverse reaction of cytidine diphosphate choline treatment which showed the adverse reaction was mild; no severe adverse events (SAEs) were reported and the clinical application was safe. Conclusion The cytidine diphosphate choline is effective and safe for acute stroke. However, it is invalid to reduce the mortality and the rate of dependency at the end of three months’ follow-up.
ObjectivesTo systematically review the patients’ satisfaction of implant supported mandibular dentures and conventional dentures.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang and VIP databases were searched to collect randomized controlled trials (RCTs) on patients’ satisfaction of implant supported mandibular dentures (IODs) and conventional dentures (CDs) from inception to November 31st, 2016. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of the included studies. Then, meta-analysis was conducted using RevMan 5.3 software.ResultsSeven randomized-controlled trials were identified. The results of meta-analysis showed that compared with CDs group, IODs group had a relatively higher level of patients’ satisfaction (SMD=1.11, 95%CI 0.79 to 1.43, P<0.001) and oral health quality of life (MD=–12.41, 95%CI –18.96 to –5.86,P<0.001).ConclusionsThe current evidence suggests that IODs may be a better choice for mandibular edentulous patients than CDs. Due to the limitations of the quality and quantity of the included studies, the above conclusions still require larger sample and high quality research to verify.
