主动脉窦瘤破裂的外科治疗体会

目的：总结主动脉窦瘤破裂的手术适应症、手术方法和预后。方法：回顾性分析2011年1月至2017年12月因主动脉窦瘤破裂于我院行外科手术治疗的130名患者资料。其中男性58例(44.62%)，女性72例(55.38%)，年龄32～75（52.72±13.87）岁。合并室间隔缺损55例(42.31%)，合并主动脉瓣关闭不全39例(30%)，合并房间隔缺损12例(9.23%)，合并三尖瓣关闭不全8例(6.15%)，合并二尖瓣关闭不全6例(4.62%)，合并主动脉夹层1例(0.77%)，合并其他心脏疾病9例(6.92%)；破裂开口起源于右冠窦119例，起源于无冠窦11例。所有患者均在中低温体外循环下行手术治疗。结果：所有患者中，2例患者围术期死亡，余128例患者随访5个月至5年，术后心功能恢复至I-II级。结论：一旦发现主动脉窦瘤破裂，应积极予以治疗。

The oncogenic impact of RNF2 on cell proliferation,invasion and migration through EMT on mammary carcinoma

Mammary carcinoma (MC) is one of most common malignancy in women, and ring finger protein 2 (RNF2) possesses various roles in vast human tumors. In MC tissues as well as in cell lines RNF2 exhibited high expression, had significant association with tumor size, lymph node status, TNM stage, patients’ poor survival, and promoted cell proliferation, colony formation, cell migration and invasion of MC cell lines which was mediated by downregulation of E-cadherin protein. These data reveal that RNF2 protein plays a vital role in the development of MC and may be a potential therapy target of MC.     

Utility of the 3‐Vessel and 3‐Vessel and Trachea Views in Prenatal Diagnosis of a Pulmonary Artery Sling

A pulmonary artery (PA) sling is a very rare congenital cardiovascular anomaly, and only a few studies have reported PA slings in fetuses. The relationship of the PA, aorta, ductus arteriosus, and trachea can be evaluated in the 3‐vessel and 3‐vessel and trachea views during fetal echocardiography. A PA sling can be detected by abnormal positioning of the left PA in relation to the trachea when sweeping from the 3‐vessel view cranially to the 3‐vessel and trachea view. Here we report 3 cases of fetal PA slings and their follow‐ups. Two cases were confirmed by postnatal echocardiography, and the other case was confirmed by a cardiovascular cast after pregnancy termination. We emphasize that the 3‐vessel and 3‐vessel and trachea views are of crucial importance in the prenatal diagnosis of a PA sling.     

Health-Related Quality of Life in KEYNOTE-010: a Phase II/III Study of Pembrolizumab Versus Docetaxel in Patients With Previously Treated Advanced,Programmed Death Ligand 1–Expressing NSCLC

Introduction

In the phase II/III KEYNOTE-010 study (ClinicalTrials.gov, NCT01905657), pembrolizumab significantly prolonged overall survival over docetaxel in patients with previously treated, programmed death ligand 1–expressing (tumor proportion score ≥ 1%), advanced NSCLC. Health-related quality of life (HRQoL) results are reported here.

针灸联合关节松动术治疗肩周炎的网状Meta分析＊

目的 运用网状Meta分析方法评价针灸联合关节松动术治疗肩周炎的疗效。方法 运用计算机检索Web of Science、PubMed、Cochrane Library、EMbase、维普（VIP）、中国知网（CNKI）、万方（Wanfang）、中国生物医学文献数据库（CBM），搜寻有关针灸联合关节松动术治疗肩周炎的随机对照试验。所有研究人员均独立纳排文献、提录资料、风险评估，对符合质量标准的RCT研究采用Stata16.0和Review Manager 5.4软件进行分析。结果 共检索出6561篇文献，最终纳入37项研究，涉及10种针灸联合关节松动术方法。总样本量2890例，其中试验组1432例，对照组1458例。网状Meta分析所得结果表明：①在总有效率方面，最好的3种治疗方法为内热针联合组、温针联合组、动筋针联合组；②在降低VAS评分方面，最好的3种治疗方法为内热针联合组、动筋针联合组、针刀联合组。结论 针灸联合关节松动术治疗肩周炎疗效总体优于单独使用，且内热针联合组具有最佳的疗效。
