胃及十二指肠食管反流对致癌剂诱发大鼠食管肿瘤的影响

目的：通过动物实验研究胃液及十二指肠内容物反流对食管肿瘤发生过程的影响。方法：通过不同手术方式制作３种动物模型：胃食管反流（Ｇ）组,单纯十二指肠食管反流（Ｄ）组,十二指肠,胃混合食管反流（ＤＧ组）及无反流对照组（Ｃ组）。术后均注射食管致癌剂甲基戊基亚硝胺（ＭＡＮＡ）,于２６周取出食管进行大体及光镜下形态学观察。结果：各反流组出现严重食管粘膜损害,病变较对照组明显加重且发生率高,病变严重程度Ｄ组〉Ｄ     

返流性食管炎并上消化道出血临床分析

目的探讨返流性食管炎(RE)并上消化道出血的发病机制和治疗方案的选择.方法对30例RE并上消化道出血进行临床观察.针对其发病机制并采用洛赛克40 mg 5%葡萄糖(或生理盐水)250 ml静滴,2次/d,共5 d.止血后予以洛赛克 莫沙必利维持治疗观察止血效果和对RE治疗效果.结果洛赛克治疗上消化道出血显效80%,总有效率96.7%(P＜0.01).对RE食管粘膜病损有显著治疗效果(P＜0.05).结论各种原因导致返流物造成食管粘膜损伤为RE发病基础.洛赛克可作为RE并上消化道出血的一线治疗药物.     

慢性咳嗽68例临床分析

目的 分析慢性咳嗽患者的病因分布。方法 对68例慢性咳嗽患者进行前瞻性研究。常规行X线胸片、肺功能、食道内镜、痰检查及血液学检查。必要时查支气管激发试验、24h食道PH值监测、鼻窦CT、纤维支气管镜及纤维鼻咽镜。根据临床表现、检查结果及特异性治疗疗效作最后诊断。结果 病因依次为咳嗽变异型哮喘30例，44．1％、鼻后滴流综合征21例，30．9％；胃食管反流病13例，19．1％；支气管结核2例，2，9％；真菌感染1例，1．5％；嗜酸细胞性支气管炎1例，1．5％。结论 慢性咳嗽最常见的病因为咳嗽变异型哮喘、鼻后滴流综合征及胃食管反流病。     

胃食管反流病致重度牙齿侵蚀的固定-活动联合修复

目的:探讨用固定-活动义齿联合修复,对胃食管反流病致重度牙齿侵蚀症患者进行咬合重建的临床效果。方法:对从2010年1月~2013年10月来我院就诊的10例胃食管反流病致重度牙侵蚀症患者采用诊断义齿过渡3~6个月,患者适应后再以诊断义齿为依据,采用固定-活动联合修复行咬合重建。分别于修复后3个月、6个月、1年、2年、3年复查。复查内容:修复体完整性、咬合稳定性、美观度、患者使用满意度。结果:整个随访期间,10例咬合重建患者面部外形改善,咀嚼功能恢复良好,患者对义齿的美观及舒适性均较为满意,配合用药后食管反流症状基本消失。结论:用固定-活动义齿联合修复,进行牙合重建能恢复患者美观,提高咀嚼功能同时后期维护简便。     

巨大肺大疱伴胃食管反流1例

肺大疱在临床工作中常见,但是巨大肺大疱伴胃食管反流症状的患者较少见.巨大肺大疱易被误诊为气胸,如果伴有胃食管反流症状,易误诊为胃食管反流性哮喘,本例患者经过正确诊断和手术治疗痊愈,对我们拓宽胃食管反流症状病因的思考非常重要.     

Acid peptic diseases: pharmacological approach to treatment

Acid peptic disorders are the result of distinctive, but overlapping pathogenic mechanisms leading to either excessive acid secretion or diminished mucosal defense. They are common entities present in daily clinical practice that, owing to their chronicity, represent a significant cost to healthcare. Key elements in the success of controlling these entities have been the development of potent and safe drugs based on physiological targets. The histamine-2 receptor antagonists revolutionized the treatment of acid peptic disorders owing to their safety and efficacy profile. The proton-pump inhibitors (PPIs) represent a further therapeutic advance due to more potent inhibition of acid secretion. Ample data from clinical trials and observational experience have confirmed the utility of these agents in the treatment of acid peptic diseases, with differential efficacy and safety characteristics between and within drug classes. Paradigms in their speed and duration of action have underscored the need for new chemical entities that, from a single dose, would provide reliable duration of acid control, particularly at night. Moreover, PPIs reduce, but do not eliminate, the risk of ulcers in patients taking NSAIDs, reflecting untargeted physiopathologic pathways and a breach in the ability to sustain an intragastric pH of more than 4. This review provides an assessment of the current understanding of the physiology of acid production, a discussion of medications targeting gastric acid production and a review of efficacy in specific acid peptic diseases, as well as current challenges and future directions in the treatment of acid-mediated diseases.
