Barrett’s esophagus: Review of natural history and comparative efficacy of endoscopic and surgical therapies

Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC). Progression to cancer typically occurs in a stepwise fashion through worsening dysplasia and ultimately, invasive neoplasia. Established EAC with deep involvement of the esophageal wall and/or metastatic disease is invariably associated with poor long-term survival rates. This guides the rationale of surveillance of Barrett’s in an attempt to treat lesions at an earlier, and potentially curative stage. The last two decades have seen a paradigm shift in management of Barrett’s with rapid expansion in the role of endoscopic eradication therapy (EET) for management of dysplastic and early neoplastic BE, and there have been substantial changes to international consensus guidelines for management of early BE based on evolving evidence. This review aims to assist the physician in the therapeutic decision-making process with patients by comprehensive review and summary of literature surrounding natural history of Barrett’s by histological stage, and the effectiveness of interventions in attenuating the risk posed by its natural history. Key findings were as follows. Non-dysplastic Barrett’s is associated with extremely low risk of progression, and interventions cannot be justified. The annual risk of cancer progression in low grade dysplasia is between 1%-3%; EET can be offered though evidence for its benefit remains confined to highly select settings. High-grade dysplasia progresses to cancer in 5%-10% per year; EET is similarly effective to and less morbid than surgery and should be routinely performed for this indication. Risk of nodal metastases in intramucosal cancer is 2%-4%, which is comparable to operative mortality rate, so EET is usually preferred. Submucosal cancer is associated with nodal metastases in 14%-41% hence surgery remains standard of care, except for select situations.     

基于中医古籍文献的升降散应用溯源及探析

通过对中医古籍中有关升降散论述的文献梳理,全面探讨其内涵。本方是在大黄、僵蚕为雏形的基础上增加蝉蜕、姜黄而成方,几经易名,终在杨璿《伤寒瘟疫条辨》中为后人所熟知。本方广泛用于治疗瘟疫,以丸剂、散剂为主,方便携带,便于服用;重用大黄旨在祛邪、逐秽;应用时视人之体质强弱和量其毒之轻重而判断用药多寡,并辅以米酒、生蜜等以顾护正气。杨璿将其由治疗“热疫”的专方扩展为治疗“表里三焦大热”的通用方剂,扩大了本方治疗疾病范围。     

翁连解毒汤治疗浊毒内蕴型溃疡性结肠炎的疗效观察

目的：探究翁连解毒汤治疗浊毒内蕴型溃疡性结肠炎（Ulcerative Colitis，UC）临床疗效及可能的作用机制。方法：选取2016年2月至2018年12月在攀枝花学院附属医院收治的浊毒内蕴型UC患者130例作为研究对象，按照入院先后顺序分为对照组和观察组，每组65例。对照组常规西医治疗，观察组加用翁连解毒汤，观察2组治疗前、完成治疗后T细胞、NK细胞、炎性反应因子、凝血功能、生命质量变化，完成治疗后总结疗效。结果：观察组患者在NK细胞、T淋巴细胞组成、CR、TNF-α、IL-1 β、ESR、内毒素、IL-10、FIB、PLT、APTT改善方面的效果较对照组更优，组间差异有统计学意义（P<0.05）。观察组患者完成治疗后的生命质量量表各维度评分及总评分改善效果优于对照组患者（P<0.05），且临床总有效率和组织病理学疗效率均高于对照组患者（P<0.05）。结论：翁连解毒汤能抑制浊毒内蕴型UC炎性反应，改善高凝状态，提高机体免疫功能，从而提高疗效和生命质量。     

基于"络病学说"分析虫类药在肿瘤患者治疗中的应用

“络病学说”作为重要的中医基础病机之一,近年来被广泛应用于肿瘤类疾病的临床诊疗中,其对于肿瘤的发生发展以及转移等机制研究与治疗均有理论指导意义。“络病”在形态与功能上与现代医学中的肿瘤微血管、微循环概念相似;瘀阻络脉与肿瘤患者血液高凝状态类似,故运用“通络法”抗肿瘤具有充足的理论依据。虫类药是动物药的别称,作为通络药的代表,善于搜刮剔络,在肿瘤的防治中起到了活血化瘀通络、攻毒散结通络、搜风解毒通络以及补益培本通络等作用。通过梳理“络病学说”的起源、发展与成熟阶段的主要思想内涵,整理并总结现代肿瘤治疗中“络病学说”的相关研究与应用,并分析虫类药在通络法中的具体应用,以期为开展中医络病防治肿瘤的临床应用提供理论依据。     

经自然腔道取标本手术在结直肠外科手术中的应用进展

随着腔镜技术的进一步发展以及微创理念应用于结直肠外科疾病的诊治中,结直肠相关疾病的诊治发生了翻天覆地的变化。由传统的经腹手术到腹腔镜手术、经自然腔道手术,再到经自然腔道取标本手术(NOSES),结直肠疾病的外科诊治在微创领域取得了巨大成果。NOSES技术是目前结直肠外科在微创领域前沿的手术方式之一,它通过经直肠、阴道取标本来避免了腹壁的辅助取标本切口,从而将结直肠外科手术进一步微创化。NOSES技术集传统腹腔镜手术的优势与现代微创外科的理念于一体,它在确保手术效果的基础上集中体现了微创、加速康复外科、功能外科、"无疤"等理念的特点。本文主要就国内外各中心开展NOSES技术在结直肠外科诊治开展中的相关经验、心得和体会进行综述。     

Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery: Diagnoses and Surgical Results in 12 Pediatric Patients

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital condition. It responds well to early diagnosis and treatment, but otherwise the prognosis is poor. We present our case series of 12 patients (mean age, 2 ± 2.58 yr; age range, 2 mo–8 yr), emphasizing the diagnostic process and discussing our surgical results. The diagnosis of ALCAPA should be suspected in infants who have dilated cardiomyopathy with electrocardiographic changes that suggest ischemia, and in older children who have isolated mitral regurgitation. When clinical suspicion is high, the results of 2-dimensional echocardiography combined with color-flow Doppler studies in expert hands can establish the diagnosis, thus avoiding angiography in critically ill infants. The treatment of choice in our patients was transfer and reimplantation of the left coronary artery onto the ascending aorta. There were 2 deaths: both were infants in extremis who underwent emergency surgery. An older child with severe ventricular dysfunction was given mechanical ventricular assistance and then heart transplantation. As of this report, all 10 survivors remained well and asymptomatic.
