239例小儿室间隔缺损修补术后残余分流的近中期随访

目的:探讨小儿室间隔缺损(ventricular septal defect,VSD)修补术后残余分流的发生原因、常见部位、预后、影响预后的因素及干预时机。方法:回顾性分析2013年1月至2017年1月重庆医科大学附属儿童医院行VSD修补术后239例残余分流患者的临床资料,包括患者性别、手术年龄、体质量、术前左右心室压差、术前VSD分流方向、补片材料、体外循环时间、残余分流的大小及部位、残余分流的血流速度,运用单因素及多因素Cox回归分析患者预后的影响因素。结果:239例残余分流患者均未再次干预,155例(64.85%)残余分流自行愈合;84例(35.15%)未愈合。小于4 mm残余分流219例,153例(69.86%)自愈;大于4 mm残余分流20例,2例(10%)自愈(P<0.005)。单因素Cox分析结果表明,术前左右心室压差(P=0.028)、体外循环时间(P=0.006)、残余分流大小(P=0.003)、残余分流血流速度(P=0.00)是影响患者预后的因素(P<0.05);而多因素Cox回归分析显示体外循环时间(P=0.017)、残余分流血流速度(P=0.019)...

Composite hemangioendothelioma of the spleen with multiple metastases: CT findings and review of the literature

Composite hemangioendothelioma (CHE) is a rare vascular neoplasm of intermediate malignant potential. Only 52 cases have been reported in the English literature, and one case previously reported occurred in the spleen. The purpose of our study was to report a 65-year-old man diagnosed as CHE primary arising from the spleen with multiple metastases.Clinical and imaging features, laboratory tests, and pathological results about CHE were described in detail in this study.The patient presented with multiple lesions in bilateral lungs and spleen that had been incidentally detected by computed tomography (CT). Except for thrombocytopenia, other laboratory tests were not significant. The CT scan of the abdomen revealed multiple round-like and irregularly mixed density masses with unclear borders in enlarged spleen. And contrast enhancement showed mild heterogeneous enhancement. CT scan also showed widespread liver, ribs, lungs, and vertebral bodies metastases. This diagnosis was confirmed by histopathological examination. The patient underwent splenectomy and still survives with tumors after six months followed-up.Due to the lack of specificity of clinical features and laboratory tests, it is necessary to combine imaging features and pathological findings to make a correct diagnosis.     

Uncoupling protein 3 genetic variants in human obesity: the c-55t promoter polymorphism is negatively correlated with body mass index in a UK Caucasian population

OBJECTIVE: To investigate whether genetic variation at the UCP3 locus contributes to human obesity. SUBJECTS: Ninety-one obese children (BMI>4 standard deviations from age related mean) and 419 Caucasian adults from the Isle of Ely Study. DESIGN: Single strand conformation polymorphism (SSCP) analysis was used to scan the coding region of the UCP3 gene in 91 severely obese children. A common polymorphism identified in this gene (c-55t) has been shown to associate with lower UCP3 mRNA expression. Polymerase chain reaction-based forced restriction digestion was used to detect this allele in Caucasian adults. Multiple regression analysis was used to determine associations between the c-55t genotype and anthropometric, energetic and biochemical indices relevant to obesity. MEASUREMENTS: For the obese children, SSCP analysis and sequencing of variants were carried out. For the Isle of Ely Study, c-55t genotype and anthropometric (body mass index, waist-hip ratio, percentage body fat), energetic (dietary fat intake, physical activity index, adjusted metabolic rate, maximum oxygen consumption) and biochemical indices (pre- and post-glucose challenge plasma triglycerides, non-esterified fatty acids, insulin and glucose) were determined. RESULTS: A previously reported missense mutation (V102I) was detected in a single obese Afro-Carribean child. Twenty-one percent of the genes examined in the Isle of Ely study carried the c-55t promoter variant. Age-adjusted body mass index (BMI) was significantly (P=0.0037) lower in carriers of this variant. CONCLUSION: Mutations in the coding sequence of UCP3 are unlikely to be a common monogenic cause of severe human obesity. In a Caucasian population the UCP3 c-55t polymorphism is negatively associated with BMI.     

外周血白细胞端粒长度和线粒体基因拷贝数对急性心肌梗死的诊断预测价值以及相关机制的探讨

目的 探究外周血白细胞端粒长度(LTL)和线粒体基因拷贝数(mtDNA?CN)对急性心肌梗死(AMI)的预测价值,并从端粒酶逆转录酶(TERT)和线粒体氧化损伤的角度探讨其相关机制.方法 选取AMI患者80例,并选同期行冠脉造影检查且结果显示冠脉大致正常者80例作为对照.收集研究对象的临床资料和空腹全血,以qPCR法检测外周血LTL、TERT mRNA、mtDNA?CN和线粒体氧化损伤程度,采用Spearman相关分析评估上述指标间的相关性.采用多因素Logistic回归分析LTL和mtDNA?CN与AMI发生风险的关系,以受试者工作曲线(ROC)评价LTL和mtDNA?CN对AMI诊断的预测价值.结果 AMI组患者外周血LTL、TERT mRNA表达水平和mtDNA?CN均显著低于对照组,线粒体氧化损伤水平显著高于对照组,差异均具有统计学意义(P<0.05).在AMI组和对照组中,LTL分别与TERT mRNA的表达水平和mtDNA?CN呈显著正相关,与线粒体氧化损伤水平呈显著负相关(均P<0.05).在AMI组中,mtDNA?CN与线粒体氧化损伤水平呈显著负相关(P=0.03),但在对照组中两者相关性无统计学意义(P=0.20).Logistic回归分析结果表明,长LTL和高mtDNA?CN是AMI的保护因素;ROC曲线分析结果表明,LTL、mtDNA?CN以及两者联合预测AMI的曲线下面积(AUC)分别为0.748、0.704、0.767.结论 外周血LTL和mtDNA?CN对AMI具有一定的预测诊断价值.AMI患者外周血LTL的缩短可能与TERT mRNA表达的降低有关,外周血白细胞线粒体氧化损伤水平的升高可能是mtDNA?CN降低和LTL缩短的重要原因.
