RESUMO

The published data on the association between MCP-1 -2518A>G polymorphism and asthma susceptibility are inconclusive. Therefore, we performed a meta-analysis to estimate the impact of MCP-1 -2518A>G polymorphism on asthma susceptibility. PubMed, Web of Science, Wanfang, and China National Knowledge Infrastructure (CNKI) databases were used to identify eligible studies. The pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were used to calculate the strength of association. Sensitivity analysis was performed to evaluate the influence of individual studies on the estimates of overall effect, and funnel plots and Egger's test were used to assess publication bias. Eight publications with 1562 asthma patients and 1574 controls were finally identified. Overall, we found no significant association between MCP-1 -2518A>G polymorphism and asthma susceptibility in any of the genetic model comparisons. After stratified analysis by ethnicity, the results showed that a significant association with asthma risk was found in Caucasians in all the genetic models. However, a protective association was found in Africans under the dominant model. The present meta-analysis suggested that the MCP-1 -2518 A>G polymorphism is a risk factor for asthma in the Caucasian population, nevertheless it has a protective effect in the African population.

RESUMO

@#Objective     To compare clinical outcomes between the performed titanium locking plate and nickel-titanium memory alloy embracing fixator for the treatment of multiple rib fractures, and to select a better internal fixator for multiple rib fractures. Methods     A total of 206 consecutive patients with multiple rib fractures were admitted to Department of Cardiothoracic Surgery in Beijing Luhe Hospital of Capital Medical University from October 2011 to September 2016. According to different treatment strategies, the patients were divided into 2 groups: a performed titanium locking plate group (a titanium plate group, n=105) and a nickel-titanium memory alloy embracing fixator group (an embracing fixator group, n=101). There were 82 males and 23 females with a mean age of 46.5±9.7 years ranging from 23 to 65 years in the titanium plate group, and 83 males and 18 females with a mean age of 44.7±10.3 years ranging from 19 to 63 years in the embracing fixator group. The preoperative data, curative outcomes, visual analogue scale (VAS) and postoperative complications were compared between the two groups. Results     There was no statistical difference in the preoperative data between the two groups, and all patients successfully completed the operation. Compared with the embracing fixator group, the incision length and operation time were shorter, intraoperative bleeding and VAS score were less, and curative outcome was better in the titanium plate group. Conclusion     The performed titanium locking plate has a great advantage in the clinic, which can be preferred.
