目的探讨幽门螺杆菌(Helicobacter pylori,H.pylori)感染与服用阿司匹林对消化性溃疡的分别的作用以及是否存在协同致病或者拮抗作用,了解消化性溃疡发病的致病因素的相互关系。方法选择在2017年6月至2018年6月进入医院进行治疗的250例消化性溃疡患者与250例非消化性溃疡患者作为研究对象,探究两组患者在服用相同的药物情况下,幽门螺杆菌感染与使用阿司匹林是否会具有协同致病作用。结果幽门螺杆菌感染合并服用阿司匹林患者胃溃疡OR值明显高于单纯幽门螺杆菌感染者以及单独服用阿司匹林患者之和(P0.05)。服用阿司匹林合并幽门螺杆菌感染十二指肠溃疡的OR值低于单纯幽门螺杆菌感染者以及单纯服用阿司匹林患者之和(P0.05)。胃溃疡合并上消化道出血的患者其服用阿司匹林的OR值为3.30,而十二指肠溃疡合并上消化道出血的患者服用阿司匹林的OR值为3.09,说明服用阿司匹林药物可引发十二指肠溃疡、胃溃疡合并出血,幽门螺杆菌感染合并服用阿司匹林胃溃疡并发上消化道出血、十二指肠溃疡并发上消化道出血OR值分别为1.17、3.05。结论幽门螺杆菌感染、服用阿司匹林药物均可增加消化性溃疡发病的风险,对胃溃疡发病具有协同作用,对十二指肠溃疡无协同作用,对消化性溃疡合并上消化道出血无协同致病作用。 相似文献

目的:分析研究老年幽门螺杆菌相关性消化溃疡的临床特征及治疗方案。方法:收集本院收治的240例老年消化性溃疡的患者,检查后按照Hp分组,则Hp阳性组患者206例,Hp阴性组患者36例,比较两组的年龄、溃疡部位、胃泌素和生长抑素水平。之后,将Hp阳性组患者等分为实验组和对照组,每组各103例,实验组给予埃索美拉唑三联疗法,对照组给予奥美拉唑三联疗法,治疗结束后评定临床效果。结果:Hp阳性组年龄和十二指肠溃疡率比Hp阴性组显著高,而胃溃疡率和生长抑素水平显著低(p0.05)。实验组和对照组Hp根除率、溃疡愈合率和不良反应发生率无明显差异(p0.05),但是临床症状消失时间实验组明显短于对照组(p0.05)。结论:老年幽门螺杆菌相关性消化溃疡的患者中,十二指肠溃疡的发病率高与胃溃疡,埃索美拉唑治疗消化性溃疡,临床症状消失快,值得临床推广。 相似文献

目的:探讨原发性十二指肠恶性肿瘤的临床特点、诊断方法和预后影响因素。方法:回顾性分析随访资料完整的45例原发性十二指肠恶性肿瘤患者的临床病理资料。结果:腺癌33例(73.3%)为主要的病理类型。主要临床表现为腹痛、上腹部不适、黄疸、消化道出血等。胃十二指肠镜、内镜逆行胰胆管造影(Endoscopic Retrograde Cholangio—Pancreatography,ERCP)、十二指肠低张造影、超声内镜、CT及B超确诊率分别为91.1%(41/45),93.3%(42/45),82.2%(37/45),75.6%(34N5),68.9%(31/45)及26.7%(12/45)。本组45例均行开腹手术,包括根治性手术,胰十二指肠切除术36例;姑息性手术,胃肠吻合术2例、肿瘤局部切除术5例、短路手术2例。根治术和姑息术后5年生存率分别为46.7%和4.4%,两组生存率差异有统计学意义(P〈O.05)。对全组45例患者的预后因素进行Cox回归分析的结果显示,手术方式、肿瘤浸润深度和淋巴节转移是影响预后的独立危险因素(均P〈0.05)。结论:原发性十二指肠恶性肿瘤缺乏特异性临床表现;胃十二指肠镜、ERCP以及十二指肠低张造影等联合检查可提高诊断率;根治性手术远期疗效较好;淋巴结转移和局部侵犯是肿瘤预后不良的重要影响因素。 相似文献

<正>消化性溃疡是一种常见的慢性疾病,包括胃和十二指肠溃疡。主要原因为幽门螺杆菌和非甾体抗炎药损害胃十二指肠黏膜屏障而导致溃疡形成。根据消化性溃疡的主要临床症状如上腹痛、上腹胀闷不适、嗳气反酸等,可将消化性溃疡归属中医胃痛、痞满、吐酸、嘈杂等证范畴。近年来,我国对消化性溃疡的研究不断深入,中西医结合治疗消化性溃疡也取得了较好的治疗效果。现就其治疗研究进展综述如下。1病因病机 相似文献

幽门螺杆菌:掀起对胃十二指肠病认识的革命 总被引:15,自引:0,他引:15
近些年来有关幽门螺杆菌的科研活动和出版物大量涌现,形成爆炸之势。现已公认,幽门螺杆菌是胃十二指肠疾病的罪魁祸首。大多数消化性溃疡、慢性胃炎和一些胃癌,是由此菌引起的。将近一个世纪以来医学界的古老信条:“无酸则无溃疡”,或将由“无幽门螺杆菌感染则无溃疡”所代替。根治胃十二指肠病的诱人前景,即将成为事实。因此可以说,幽门螺杆菌的发现,是对胃十二指肠疾病认识的一次革命。 相似文献

我院自1986年6月至1989年6月检查了634例病人的胃粘膜,从幽门弯曲菌(CP)的细菌学、致病性、病理学、诊断方法及药物治疗等方面进行了研究,探讨CP与慢性胃炎及消化性溃疡的关系。结果发现CP有两种形态并与空弯菌不同,不产生肠毒素;消化性溃疡的CP检出率为80.9%,慢性胃炎为41.6%,显著高于正常胃粘膜(3.7%);CP与消化性溃疡、慢性胃炎,十二指肠炎特别是活动性炎症有密切关系;CP对胃型上皮或粘液有某种亲和性;观察到上皮细胞破溃处有大量细菌聚集,CP有致细胞病变的能力。用阿的平代替吖啶橙荧光染色,并制成CP感染快速诊断试剂盒。呋喃唑酮促进溃疡愈合,使45~73%病例CP消失,50~70%胃炎好转。但有复发,根除CP有困难。 相似文献

目的研究慢性乙型肝炎及乙肝肝硬化合并消化性溃疡患者与幽门螺杆菌(Helicobacter pylori,H.pylori)感染的相关关系。方法选择2012年1月至2014年12月宣汉县人民医院收治的慢性乙型肝炎合并消化性溃疡患者108例作为A组,选择同期收治的乙肝肝硬化合并消化性溃疡患者65例作为B组。以快速尿素酶方法检测H.pylori。应用免疫印迹法急性H.pylori抗体分型。结果 A组患者H.pylori阳性率为67.6%,B组患者H.pylori阳性率为24.6%。A组胃溃疡患者H.pylori阳性率为11.4%,十二指肠溃疡患者H.pylori阳性率为94.5%;B组胃溃疡患者H.pylori阳性率为11.5%,十二指肠溃疡患者H.pylori阳性率为33.3%。A组及B组患者中十二指肠溃疡H.pylori感染率均显著高于胃溃疡H.pylori感染率(P0.05)。两组胃溃疡患者的H.pylori阳性率比较差异无统计学意义(P0.05),十二指肠患者的H.pylori阳性率在A、B两组间差异有统计学意义(χ2=48.528,P0.01)。两组患者H.pylori抗体血清分型表达阳性率比较差异无统计学意义(χ2=0.464,P0.05)。结论 H.pylori感染可能是慢性乙肝、乙肝肝硬化消化性溃疡发生的始动因素,尤其在慢性乙肝合并十二指肠溃疡的发病中可能起重要作用,在乙肝肝硬化合并十二指肠溃疡疾病的发病中可能只是其中因素之一。 相似文献

In 277 consecutive episodes of suspected upper gastrointestinal bleeding, lesions bearing stigmata of recent haemorrhage (stigmata) were found by endoscopy in 110 (47%) out of 233 patients who were judged to have bled; 78 (33%) had lesions without stigmata, and in 45 (19%) no lesion was seen. Results in 176 entirely unselected admissions for upper gastrointestinal bleeding were similar.Forty-eight chronic duodenal and 41 chronic gastric ulcers were identified by endoscopy. Stigmata were found in 27 (56%) and 33 (80%) of these cases respectively. Sixteen patients had multiple lesions, and in 12 (75%) the presence of stigmata permitted diagnosis of the source of the haemorrhage. Stigmata were more likely to be seen in cases of duodenal ulcer, Mallory-Weiss lesions, and oesophageal varices when endoscopy was performed within 12 hours of bleeding, but were as common in cases of gastric ulcer after longer intervals.In the absence of stigmata one out of 21 patients with duodenal ulcer had further haemorrhage and one other needed emergency surgery; no patient with gastric ulcer had further haemorrhage or needed emergency surgery. In contrast, when stigmata were present 15 of the 27 patients with duodenal ulcer (56%) had further haemorrhage and 17 (63%) needed emergency surgery; of the 33 patients with gastric ulcer, 10 (30%) had further haemorrhage and 15 (45%) required emergency surgery. Superficial mucosal lesions may have been the source of haemorrhage when an ulcer unmarked by stigmata was seen at endoscopy. Stigmata were superior to any other single factor or combination of factors in predicting rebleeding and the need for emergency surgery. 相似文献

Immunohistochemical Detection of Helicobacter pylori in the Surface Mucous Gel Layer and Its Clinicopathological Significance 总被引:2,自引:0,他引:2
Background Attempts have been made to develop an accurate method for detecting Helicobacter pylori in histological sections.
Materials and Methods. Biopsy specimens were obtained from the stomachs of 167 patients with gastric ulcer (33), duodenal ulcer (52), gastroduodenal ulcer (15), chronic gastritis (45), and normal mucosa (22) before antimicrobial treatment and from 108 of these patients after treatment. Biopsy specimens were (1) cultured, (2) fixed in 10% buffered formalin, or (3) fixed in Carnoy's solution. The latter method was employed to preserve the surface mucous gel layer (SMGL) covering gastric surface mucous cells. Histological sections were stained with hematoxylin and eosin (H&E), with immunostaining using a commercially available polyclonal anti- H. pylori antibody.
Results. Cultures were positive for H. pylori in 61% of the cases before treatment and in 16% after treatment; by H&E staining using formalin-fixed materials: 70% and 9%; by immunostaining using formalin-fixed materials: 78% and 21%; and by immunostaining using Carnoy-fixed materials: 85% and 41% of biopsy speciemens, respectively. The difference in detection rates between materials fixed in formalin and those in Carnoy's solution was due to the detection of H. pylori in the SMGL by the latter, especially after antimicrobial treatment.
Conclusions. Immunostaining for H. pylori using materials fixed in Carnoy's solution revealed H. pylori in the SMGL as well as on the surface mucous cells and in the gastric pits and permitted the optimal detection of H. pylori in tissue sections. 相似文献

An examination of the occurrence and distribution of phthalate esters in the alimentary canal of a polyhybrid of Tilapia gave evidence of different and selective patterns of distribution in the organ tissues: the phthalate esters were shown to be concentrated in the stomach and anterior intestine. The restricted distribution of phthalate esters can have implications for the physiology of the digestive system. The phthalates, stored in the oxyntic cells of the gastric tubular glands, probably interfere with the digestive process. The strategic location of the enterocytes in the anterior intestine implies that they can hamper the reabsorption of digestion products. The endocrine disrupting effects known for these chemicals are probably related to the absorption of them via the alimentary canal. 相似文献

玛曲渔场几种裂腹鱼类消化道的形态结构与其食性的相互关系 总被引:3,自引:0,他引:3
本文对玛曲渔场几种裂腹鱼类消化道的大体形态及显微结构进行了观察与比较,并对其结构与食性的关系作了初步探讨,结果如下:(1)这几种裂腹鱼类消化道的大体形态同林浩然(1962)报道的鲤科鱼类者一致,但显微结构差异甚大。与Mohsin(1961)报道的G.giurus鱼的显微结构相似。(2)各种硬骨鱼类分泌粘液的细胞组成不同,这种组成与食性有关。食道上皮除复层鳞形上皮外,还有复层柱状上皮。食道肌层的纤维走向与肠部者相反。(3)鱼类消化道的形态结构与其食性一致,主要表现在口腔、咽、食道和肠的长短方面。肠的显微结构,几乎没有对特有食性的适应变化。

胃癌组织中溶菌酶的免疫组织化学及其与浸润转移的关系 总被引:1,自引:0,他引:1
应用微波-SP法免疫组化技术,检测了97例胃癌和30例手术胃切端正常胃粘膜组织中溶菌酶(LZM)表达状况。其阳性率分别为85.6%和66.7%,前者显著高于后者(P<0.05)。LZM在胃癌中的表达阳性率比较,差分化癌和粘液细胞癌均显著高于分化型腺癌(P值均<0.05),有淋巴结转移性胃癌显著高于无淋巴结转移者(P<0.005)。在一组原发部位和淋巴结转移性胃癌配对标本中,LZM表达无明显差异性,提示胃癌LZM活性增高发生在淋巴结转移之前。结果表明,LZM表达与胃癌细胞的分化程度及生物学行为密切相关 相似文献
