A preliminary training set of spectra derived from 40 EC patients and 30 healthy women were used to develop a proteomic model that effectively discriminated cancer patients from healthy women. The training set had a specificity of 100% and sensitivity of 92.5% in the EC detection. A blind test set, including 20 new cancer cases and 10 healthy women, was used to validate the sensitivity and specificity of this multivariate model, which had a corresponding results of 60% in specificity and 75% in sensitivity, respectively. The combination of SELDI-TOF-MS with bioinformatics tools could help find new biomarkers and establish the detection of EC with high sensitivity and specificity.展开更多

目的:本研究旨在探讨身体质量指数(body mass index,BMI)与子宫内膜癌之间的因果关系。方法:使用全基因组关联研究(GWAS)的公开汇总数据集进行孟德尔随机化(MR)分析。从171977名欧洲血统参与者的汇总数据中,总共提取37个单核苷酸多态性(...目的:本研究旨在探讨身体质量指数(body mass index,BMI)与子宫内膜癌之间的因果关系。方法:使用全基因组关联研究(GWAS)的公开汇总数据集进行孟德尔随机化(MR)分析。从171977名欧洲血统参与者的汇总数据中,总共提取37个单核苷酸多态性(SNP)作为暴露BMI的工具变量。子宫内膜癌的GWAS汇总数据来自子宫内膜癌协会联盟(12906例病例和108979例对照)。采用逆方差加权(IVW)作为MR的主要分析方法,并辅以加权中位数(WME)、MR-Egger法、简单众数法(SM)和加权众数法(WM)。同时进行了多效性分析、异质性分析和留一敏感性分析,以进一步评估BMI与子宫内膜癌之间的因果关系。结果:IVW分析发现,BMI与子宫内膜癌之间存在因果关系(OR:1.734,95%CI:1.442,2.084),BMI每增加一个标准差(4.77 kg/m^(2))与子宫内膜癌总体风险增加相关。异质性分析显示纳入SNP之间无异质性(P=0.055)。水平多效性分析显示BMI与子宫内膜癌之间的相关性无水平多效性(MR Egger截距=0.010,P=0.278)。结论:BMI与子宫内膜癌之间存在因果关系,BMI升高增加患子宫内膜癌的风险。展开更多
目的观察子宫内膜癌患者体重指数(body mass index,BMI)、胰岛素抵抗(insulin resistance,IR)及炎性因子表达水平的变化,并探讨其对远期预后的影响。方法选取2011年8月至2014年3月于本院就诊的新发子宫内膜癌患者110例作为观察组,另以6...目的观察子宫内膜癌患者体重指数(body mass index,BMI)、胰岛素抵抗(insulin resistance,IR)及炎性因子表达水平的变化,并探讨其对远期预后的影响。方法选取2011年8月至2014年3月于本院就诊的新发子宫内膜癌患者110例作为观察组,另以60例同期体检的健康妇女作为对照组,观察两组研究对象的BMI、空腹血糖(fasting glucose,FG)、空腹胰岛素(fasting insulin,FIN)及炎性因子水平。采用稳态模型评估法计算胰岛素抵抗指数(HOMA-IR),Pearson相关分析BMI、IR与炎性因子的相关性,多因素Logistic回归分析BMI、IR及炎性因子与预后的关系。结果与健康对照组比较,观察组患者BMI、HOMA-IR、CRP、TNF-α、IL-6及IFN-γ水平均明显高于对照组(P均<0.05)。不同分期时,Ⅲ、Ⅳ期子宫内膜癌患者BMI、IR及血清炎症因子水平较Ⅰ期时均显著增加(P均<0.05)。Pearson相关分析结果显示,BMI与CRP呈正相关(r=1.72,P=0.033),而与其他炎性因子未见明显相关性;IR与CRP、TNF-α、IL-6和IFN-γ均呈正性相关(P均<0.05)。多因素Logistic回归分析显示BMI、IR、CRP、TNF-α、IL-6及IFN-γ水平均为影响子宫内膜癌预后的危险因素(P均<0.05)。结论代谢及炎症等因素导致机体出现IR,促进肿瘤生长与转移,影响子宫内膜癌的进展和预后。展开更多
