Associations of IL-27 Polymorphisms and Serum IL-27p28 Levels With Osteosarcoma Risk

Interleukin (IL)-27 is a novel cytokine secreted by stimulation of antigen-presenting cells. No previous studies currently reported the role of IL-27 in the carcinogenesis of osteosarcoma. We aimed to investigate the association of IL-27 polymorphisms and serum IL-27p28 with osteosarcoma risk in a Chinese population.One hundred and sixty osteosarcoma patients and 250 health controls were selected. IL-27 gene -964 A/G, 2905 T/G, and 4730 T/C polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism. Enzyme-linked immunosorbent assay were used to detect serum IL-27p28 levels.The serum IL-27p28 levels were significantly lower in osteosarcoma patients compared with those in controls (P < 0.01). Serum IL-27p28 levels in stages III–IV were lower than those in stages I–II of osteosarcoma (P < 0.05); similar results were also found in patients with metastasis, that is, patients with metastasis have higher IL-27p28 levels than those without metastasis (P < 0.05). There were no associations between genotype and allele frequencies of IL-27 -964 A/G, 2905 T/G, 4730 T/C, and the risk of osteosarcoma (P > 0.05). Stratification analysis also failed to show the associations between -964 A/G, 2905 T/G, and 4730 T/C polymorphisms and the clinical stage and metastasis of osteosarcoma (P > 0.05). Three possible haplotypes (A^-964T²⁹⁰⁵T⁴⁷³⁰, G^-964T²⁹⁰⁵T⁴⁷³⁰, and G^-964G²⁹⁰⁵C⁴⁷³⁰) were identified, but no associations were found between them and the osteosarcoma risk (P > 0.05).This study indicates that the lower serum IL-27p28 levels may be associated with development and progression of osteosarcoma, but IL-27 gene -964 A/G, 2905 T/G, and 4730 T/C polymorphisms and their haplotypes are not associated with osteosarcoma risk.     

One‐Year Clinical Outcome of a Randomized Trial of Polymer‐Free Paclitaxel‐Eluting Stents Versus Biodegradable Polymer‐Based Rapamycin‐Eluting Stents in Patients with Coronary Heart Disease

Background: More widespread use of drug‐eluting stents (DES) to treat coronary heart disease (CHD) has recently generated more attention to thrombosis, which was relative to the polymer. Polymer‐free and biodegradable polymer‐based stents are more frequently studied, but their efficacy on preventing detrimental clinical events is unclear. Methods and Results: To assess whether polymer‐free paclitaxel‐eluting stent (YINYI stent) was noninferior or equivalent to biodegradable polymer‐based rapamycin‐eluting stents (EXCEL stent) in preventing detrimental clinical cardiovascular events, a total of 167 consecutive CHD patients requiring DES implantation were randomly divided into the YINYI group (n = 82) and the EXCEL group (n = 85). The primary end‐point was major adverse cardiac events (MACE). The secondary end‐points included stent thrombosis events, all‐cause mortality, and rehospitalization. The study was designed to test the noninferiority or equivalence of the YINYI stent compared with the EXCEL stent with respect to one‐year MACE according to a noninferiority or equivalence margin of 0.1. One‐year MACE was 6.10% in the YINYI group versus 5.88% in the EXCEL group. The lower limit of the one‐sided 95% confidence interval was ?0.0582 (P = 0.002 from the test for noninferiority). The 95% confidence interval for the equivalence test was [?0.0698, 0.0742] (P₁=0.004 and P₂=0.007 from 2 times the 1‐sided test for equivalence). There was no statistically significant difference in thrombosis events, all‐cause death, and rehospitalization (all P > 0.05). Conclusions: In this small randomized trial, polymer‐free paclitaxel‐eluting stents appear to be noninferior or equivalent to biodegradable polymer‐based rapamycin‐eluting stents.

沈阳地区金黄色葡萄球菌感染患者万古霉素治疗无效的研究

目的探讨沈阳地区部分医院万古霉素治疗金黄色葡萄球菌感染患者失败的因素,为有效治疗提供依据。方法 2011年6月-2012年8月对临床分离的172株金黄色葡萄球菌中耐甲氧西林金黄色葡萄球菌(MRSA)102株、甲氧西林敏感金黄色葡萄球菌(MSSA)70株,采用E-test法检测其对万古霉素最低抑菌浓度MIC值;用含万古霉素4.0μg/ml的脑心浸液琼脂培养基筛选异质性万古霉素中介耐甲氧西林金黄色葡萄球菌(hVISA),在无万古霉素血平皿培养基中对MRSA进行连续传代培养,检测其对万古霉素MIC值的变化。结果 172株临床分离金黄色葡萄球菌,对万古霉素MIC值在(1.0~2.0)μg/ml有146株,占84.89%;102株MRSA对万古霉素MIC值在(1.0~2.0)μg/ml有88株,占86.27%,其中有两株MIC值为(2.5~3.0)μg/ml;70株MSSA对万古霉素MIC值在(1.0~1.5)μg/ml有46株,占65.71%,其余<1.0μg/ml;含万古霉素4.0μg/ml的脑心浸液琼脂培养基未筛选出hVISA,也未筛选出对万古霉素MIC值>8.0μg/ml的VRSA;体外传代培养发现,MRSA对万古霉素的MIC值随传代次数呈现一定变化规律。结论沈阳地区hVISA检出率极低,大部分临床治疗失败可能与菌株MIC值漂移有关,MIC值漂移菌株脱离抗菌药物环境连续传代,其MIC值较初始分离时未见下降,提示MIC值的漂移可能也涉及到了稳定的遗传变异,其机制有待进一步研究。
