幽门管区炎性病变与幽门螺杆菌感染关系的探讨

幽门螺杆菌(Hp)感染是十二指肠球部溃疡、慢性活动性胃炎重要的致病因素，其感染率分别是82％-100％和72．3％-95％，但我们在一组幽门管区粘膜充血水肿明显或伴有糜烂，病理显示活动性病变的患，Hp感染率很底。本就这一问题做初步探讨。

目的探究不同分型幽门螺杆菌(Helicobacter pylori,HP)感染对消化性溃疡患者血清IL-10、IL-17及TNF-α水平表达的影响及意义。方法选取消化性溃疡患者158例,其中HP阳性109例(HP I型组58例,HP II型组51例),HP阴性组49例。观察IL-10、IL-17及TNF-α水平,比较各组中胃溃疡与十二指肠溃疡患者血清IL-10、IL-17及TNF-α表达水平。结果 HP I型组、HP II型组IL-10、IL-17及TNF-α水平高于HP阴性组(P均0.05);HP I型组IL-10、IL-17及TNF-α水平又高于HP II型组(P均0.05)。HP I型感染者中,十二指肠溃疡患者血清IL-10、IL-17及TNF-α水平显著高于胃溃疡患者(P均0.05)。HP II型感染者中,胃溃疡与十二指肠溃疡患者IL-10、TNF-α水平比较差异无统计学意义(P均0.05);十二指肠溃疡患者血清IL-17水平高于胃溃疡患者,差异具有统计学意义(P0.05)。HP阴性患者中十二指肠溃疡患者与胃溃疡患者血清IL-10、IL-17、TNF-α水平比较差异无统计学意义(P均0.05)。结论不同分型HP感染的消化性溃疡患者血清IL-10、IL-17及TNF-α水平存在显著的差异,对于临床诊断具有一定的参考价值。     

胃上皮化生、幽门螺杆菌感染和十二指肠溃疡的关系

近年来大量研究资料表明幽门螺杆菌(Hp)是引起消化性溃疡的重要致病因素,十二指肠溃疡(DU)患者Hp的感染率为90％。正常情况下Hp主要定植于胃型上皮,也有DU患者十二指肠可见胃上皮化生,可供Hp定植引起溃疡形成。我们对79例DU患者的十二指肠胃上皮化生、Hp感染与DU发病及愈合的关系进行分析,并与胃溃疡(GU)、功能性消化不良(FD)患者资料进行对照,分析如下。     

幽门螺杆菌napA基因克隆及高效表达与鉴定

世界上约有超过50％的人口感染幽门螺杆菌。目前，已证实这种革兰氏阴性的微需氧菌与慢性浅表性胃炎（胃黏膜炎症）、慢性活动性胃炎（胃黏膜炎症伴有分叶核白细胞浸润）、胃溃疡疾病（胃及十二指肠溃疡）和胃癌密切相关。幽门螺杆菌产生一系列独特的毒力因子,其中包括尿素酶、细胞空泡毒素和中性粒细胞激活蛋白（H矿NAP）。Hp-NAP可以激起中性粒细胞的天然免疫反应,     

534例消化性溃疡伴幽门螺杆菌感染的年龄特点分析

本文分析５３４例消化性溃疡及其幽门螺杆菌（ＨＰ）感染的年龄特点，结果表明：老年人胃溃疡发生率增高，十二指肠溃疡发生率降低，其胃溃疡的ＨＰ感染率显著降低，并显著低于同龄十二指肠溃疡。提示老年人胃溃疡和ＨＰ关系较小，治疗老年人胃溃疡宜采取相应对策。     

肥大细胞脱颗粒在幽门螺杆菌致病中的作用

目的 研究肥大细胞（MC）在幽门螺杆菌（H pylori)发病中的作用。方法 选胃镜检查者87例，其中诊断十二指肠溃疡（DU）33例，浅表性胃炎45例，糜烂性胃炎9例。取胃窦、体部活检分别作组织病理学（HE染色）及H pylori检查（快速尿素酶、培养及Warthin-Starry银染），免疫组织化学染色（ABC法）后分别计算粘膜及粘膜下的完整和脱颗粒MC数。结果 MC计数在H pylori阳性和H pylori阴性组间无明显差别（P＞0．05），但前者粘膜内MC脱颗粒者明显多于后者（分别为43％和23％，P＜0．01）。MC计数与粘膜炎症程度无明显关系，但在活动性炎症时显著高于非活动性炎症组（P＜0．05）。各病变组间MC计数也无显著差异。结论 MC可能在粘膜H pylori相关炎症的发生发展中起着重要作用。     

Helicobacter pylori infection, glandular atrophy and intestinal metaplasia in superficial gastritis, gastric erosion, erosive gastritis, gastric ulcer and early gastric cancer

AIM: To evaluate the histological features of gastric mucosa, including Helicobacter pylori infection in patients with early gastric cancer and endoscopically found superficial gastritis, gastric erosion, erosive gastritis, gastric ulcer. METHODS: The biopsy specimens were taken from the antrum, corpus and upper angulus of all the patients. Giemsa staining, improved toluidine-blue staining, and Hpylori-specific antibody immune staining were performed as appropriate for the histological diagnosis of H pylori infection. Hematoxylin-eosin staining was used for the histological diagnosis of gastric mucosa inflammation, gastric glandular atrophy and intestinal metaplasia and scored into four grades according to the Updated Sydney System. RESULTS: The overall prevalence of H pylori infection in superficial gastritis was 28.7%, in erosive gastritis 57.7%, in gastric erosion 63.3%, in gastric ulcer 80.8%, in early gastric cancer 52.4%. There was significant difference (P<0.05), except for the difference between early gastric cancer and erosive gastritis. H pylori infection rate in antrum, corpus, angulus of patients with superficial gastritis was 25.9%, 26.2%, 25.2%, respectively; in patients with erosive gastritis 46.9%, 53.5%, 49.0%, respectively; in patients with gastric erosion 52.4%, 61.5%, 52.4%, respectively; in patients with gastric ulcer 52.4%, 61.5%, 52.4%, respectively; in patients with early gastric cancer 35.0%, 50.7%, 34.6%, respectively. No significant difference was found among the different site biopsies in superficial gastritis, but in the other diseases the detected rates were higher in corpus biopsy (P<0.05). The grades of mononuclear cell infiltration and polymorphonuclear cell infiltration, in early gastric cancer patients, were significantly higher than that in superficial gastritis patients, lower than that in gastric erosion and gastric ulcer patients (P<0.01); however, there was no significant difference compared with erosive gastritis. The grades of mucosa glandular atrophy and intestinal metaplasia were significantly highest in early gastric cancer, lower in gastric ulcer, the next were erosive gastritis, gastric erosion, the lowest in superficial gastritis (P<0.01). Furthermore, 53.3% and 51.4% showed glandular atrophy and intestinal metaplasia in angular biopsy specimens, respectively; but only 40.3% and 39.9% were identified in antral biopsy, and 14.1% and 13.6% in corpus biopsy; therefore, the angulus was more reliable for the diagnosis of glandular atrophy and intestinal metaplasia compared with antrum and corpus (P<0.01). The positivity rate of glandular atrophy and intestinal metaplasia of superficial gastritis with H pyloripositivity was 50.7%, 34.1%; of erosive gastritis 76.1%, 63.0%; of gastric erosion 84.8%, 87.8%; of gastric ulcer 80.6%, 90.9%; and of early gastric cancer 85.5%, 85.3%, respectively. The positivity rate of glandular atrophy and intestinal metaplasia of superficial gastritis with H pylorinegativity was 9.9%, 6.9%; of erosive gastritis 42.5%, 42.1%; of gastric erosion 51.1%, 61.9%; of gastric ulcer 29.8%, 25.5%; and of early gastric cancer 84.0%, 86.0%, respectively. The positivity rate of glandular atrophy and intestinal metaplasia of superficial gastritis, erosive gastritis, gastric erosion, and gastric ulcer patients with H pylon positivity was significantly higher than those with H pylori negativity (P<0.01); however, there was no significant difference in patients with early gastric cancer with or without H pylori infection. CONCLUSION: The progression of the gastric pre-cancerous lesions, glandular atrophy and intestinal metaplasia in superficial gastritis, gastric erosion, erosive gastritis and gastric ulcer was strongly related to H pylori infection. In depth studies are needed to evaluate whether eradication of H pylori infection will really diminish the risk of gastric cancer.     

Helicobacter pylori-Negative Duodenal Ulcer

Most patients with chronic duodenal ulcer (DU) craters have gastritis associated with Helicobacter pylori (HP), now thought to be the major cause of DU. A smaller proportion of DU patients have no detectable HP. In this study, we examined the frequency and causes of HP-negative duodenal ulcers. In 302 consecutive patients with endoscopic diagnosis of duodenal ulcer, 284 (94%) were found to have associated HP gastritis, whereas 18 (6%) were HP-negative on histology, culture, and urease test. The largest subgroup of HP-negative patients (8/18) was made up of those who had been taking nonsteroidal antiinflammatory drugs (NSAIDs), followed closely (4/18) by patients with recent intake of antibiotics. Causes of DU in the remaining subgroups included two patients with duodenal Crohn's disease, two with Gastrospirillum hominis infection, one with penetrating carcinoma of the pancreas and one with no detectable cause. We conclude that, although the most common causal factor of duodenal ulcer is HP, some 6% of DU's will be HP-negative, signaling unusual etiology. It is now important to identify the cause of duodenal ulcer so as to initiate appropriate therapy.

原发性胆汁反流性胃炎与幽门螺旋杆菌感染性胃炎的对比研究

目的比较原发性胆汁反流性胃炎（BRG）与幽门螺旋杆菌（HP）感染相关性胃炎的差异，并探索影响原发性BRG发病的危险因素。 方法选择宁夏人民医院2017年1月至2018年1月168例慢性胃炎患者，按是否有胆汁反流及HP感染将纳入研究对象分为2组。A组为内镜诊断为BRG伴或不伴HP感染患者67例，B组为有明确的HP感染的慢性胃炎但无胆汁反流患者101例。对2组人口统计学数据、合并疾病、上消化道受累模式及病理学特征进行统计学分析。 结果A组患者年龄在61~70岁的发病人数最多，与B组比较，差异有统计学意义（P=0.033），2组患者发病年龄整体比较，差异无统计学意义（P>0.05）。A组男女比例接近1: 2，而B组男女比例为2: 1，差异有统计学意义（P<0.05）。2组胃炎患者最常见的症状均为上腹部疼痛或不适（A组为71.64%，B组为73.63%），差异无统计学意义（P=0.871）；A组患者次最常见的症状是反酸和胃灼热（40.29%），与B组（15.84%）比较，差异有统计学意义（P=0.000）。发现糖尿病、高血压、胆囊切除在A组患者的检出率均较B组明显高；体重过轻在A组患者中更常见，超重在B组患者中更常见，2组患者BMI值比较，差异无统计学意义（P=0.097）；而反流性食管炎在A组患者中的检出率明显高于B组，差异有统计学意义（P=0.028）；对于溃疡性疾病（胃溃疡、十二指肠溃疡），则在B组中的检出率更高，差异有统计学意义（P=0.001）；病理显示化生性萎缩在A组患者中更常见，而非化生性为萎缩则在B组中更常见，但差异无统计学意义（P>0.05）。 结论原发性BRG与HP感染相关性胃炎相比较，有相似之处，但在发病年龄、临床表现、合并疾病及病理学相关表现上仍有差异。女性患有反流食管炎及糖尿病、既往有胆囊切除病史与原发性BRG的发生密切相关。     

肝硬化患者胃粘膜幽门螺杆菌检出的初步观察

本文对72例肝硬化患者进行了胃镜下胃粘膜活检检测幽门螺杆菌（HP）。组织学检查HP阳性42例，阳性率58．33％，HP感染和患者的肝功能Child分级无明显相关，亦和胃镜下食管静脉曲张的有无及曲张的严重程度无显著相关，而和胃粘膜活动性炎症及二十指肠溃疡的发生有明显相关。认为在肝硬化患者中，所存在的慢性活动性胃炎的主要病因仍是HP感染，HP可能在肝源性十二指肠溃疡的发病机制中起重要作用。     

十二指肠溃疡伴Hp相关性胃窦炎时生长抑素含量与D细胞超微结构研究

目的探讨十二指肠溃疡（DU）伴幽门螺杆菌（Hp）相关性胃窦炎时生长抑素（SS）含量与D细胞超微结构变化。方法采用放免法测定52例活动期十二指肠溃疡及60例非溃疡对照组空腹血浆及胃窦粘膜组织中SS含量，同时应用免疫组化及免疫电镜分别于光镜和透射电镜下观察了粘膜组织中D细胞的数量和超微结构。结果42例Hp阳性DU患者，胃窦粘膜病理多呈中重度炎性变化；血浆及粘膜组织中SS含量显著降低（P＜0．01），D细胞数量显著减少（P＜0．01）。粗面内质网扩张，核糖颗粒脱失。结论由于Hp相关性胃窦炎的影响，DU患者胃窦D细胞数量上减少，合成和分泌SS功能亦降低。
