老年人消化性溃疡与慢性萎缩性胃炎的相关性研究

目的研究老年人消化性溃疡与慢性萎缩性胃炎的相关性。方法对十二指肠溃疡（DU）、胃溃疡（GU）和复合性溃疡（CU）的老年患者胃窦、胃窦胃体交界处和胃体黏膜以及慢性胃炎（CG）患者胃窦黏膜活检标本进行组织学检查,统计各自胃黏膜的萎缩、肠化生、慢性炎症、活动性和幽门螺杆菌（Hp）感染的发生率。结果 DU患者胃窦、胃窦胃体交界处和胃体黏膜的萎缩发生率分别为54.0%、8.0%和16.0%,肠化生发生率分别为19.0%、6.0%和4.0%。其胃窦黏膜肠化生的发生率明显低于相应的GU、CU或CG者。3种消化性溃疡和CG患者均存在胃窦部慢性炎症,且老年消化性溃疡患者胃体部炎症的发生率较高,其胃炎活动性以胃窦部为主,且均较CG者高。结论老年人消化性溃疡均可有胃窦部灶性萎缩和肠化生发生,但DU胃窦黏膜肠化发生率最低,这可能是老年DU患者罹患胃癌危险性较低的原因之一。

序贯疗法治疗幽门螺杆菌阳性的十二指肠球部溃疡患者的临床分析

幽门螺旋杆菌（Hp）在十二指肠球部溃疡患者中检出率高达90％～100％。目前公认HD感染是十二指肠溃疡的重要病因，发现根除此菌后，溃疡病的复发率显著降低。作者自2006年8月至2007年9月试用序贯疗法方案治疗HD阳性十二指肠球部溃疡与经典三联疗法对比研究，报道如下。     

胃上皮化生、幽门螺杆菌感染和十二指肠溃疡的关系研究

目的：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感染率约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。本研究是经胃镜检查确诊为活动期十二指肠溃疡患者，检测十二指肠胃上皮化生、HP感染的情况，并与胃溃疡（GU）、功能性消化不良（FD）患者资料进行对照。结论：本组资料表明：十二指肠球部HP的检出率在DU、GU、FD三组差异无显著性。DU、GU、FD组的十二指肠胃上皮化生检出率分别为57．9％、11．1％、16．7％，3组患者在十二指肠球部均可出现胃上皮化生，但DU组显著高于其他2组，推测胃上皮化生与DU组的发病有关。     

幽门螺杆菌血清分型与上消化道疾病的关系

目的 探讨幽门螺杆菌(helicobacter pylori,Hp or H.pylori)分型与消化道不同疾病的关系。方法 入选198例Hp阳性的胃镜检查患者，采用免疫印迹法进行Hp的血清学分型，并取胃窦黏膜经HE染色观察胃窦黏膜病理组织学变化。结果 198例患者中检出HpI型菌株173例(87．4％)，Ⅱ型菌株25例(12．6％)。I型较II型Hp感染者胃镜下消化性溃疡、胃癌的比例更高，P=0.012；与胃炎组比较，十二指肠球部溃疡组、胃癌组的I型感染者更高（P值分别为0.026、0.048），而与胃溃疡组无显著差别(P=0.125)。病理组织学改变I型较II型Hp感染者的结果更为严重（P=0.038）。结论 临床上消化道疾病患者Hp感染以I型菌株最为多见。Hp感染的分型诊断有助于对胃、十二指肠疾病类型及病情的判断，I型菌株感染者需要更为积极的治疗。

Gastroduodenal fistulae and double pyloric canal

Four cases of endoscopically proven gastroduodenal fistulae (double pyloric canal) are presented, and ten case reports in the literature are reviewed. The fistula develops from a penetrating gastric ulcer. Presumably, the ulcer becomes adherent to adjacent duodenum and penetrates further to establish a fistulous connection, which ultimately becomes lined with mucosa, creating a second pyloric canal. Fistulae between the lesser curve of the antrum and superior fornix of the duodenal bulb were the commonest (9 out of 14). Fistulae also form between the lesser curve of the body of the stomach and the duodenal bulb or fourth part of the duodenum. Gastro-gastric fistula and a fistula into the inferior fornix of the duodenal bulb from a pyloric ulcer have been described. In two of the four cases in this series fistulae had formed from the greater curve of the antrum to the inferior fornix of the duodenal bulb, an entity not previously described. Radiologic appearances may be confused with an antral carcinoma, an ulcerating carcinoma, Crohn's disease, or lymphoma. The presence of previous ulceration and evidence of scarring should aid in avoiding confusion with malignancy. The term gastroduodenal fistula is suggested to describe double pyloric canal.     

溴甲酚紫色素内镜诊断胃幽门螺杆菌感染的价值

幽门螺杆菌(Hp)感染是消化性溃疡和慢性胃炎的重要发病因素,Hp在胃内的分布不均匀。为使Hp感染的区域在内镜下变为可视,作者以溴甲酚紫—尿素喷洒成色内镜检测有无Hp感染及其所在部位。作者共检测各种胃十二指肠疾病256例,男185例,女71例,平均年龄40.6岁。做法是在内镜下经活检孔道将Hp识别液5～10ml喷洒在球部、胃窦幽门区,有糜烂、充血、溃疡、疣状凹陷等病变处,1～2分钟后上述各部如呈紫色即示Hp存在。结果本组阳性者128例,阳性率50.0%。在阳性着色区做粘膜活检,做涂片和石蜡切片用作者研制的乙醇中性红染色,结果100%检出Hp。未着色者128例,也作粘膜活检,检查有无Hp,结果仅有2例浅表性胃炎有Hp感染,染色法的假阴性率1.56%。作者认为,本技术准确、无创、简便、实用,可作为Hp诊断及治疗清除的可靠指标。     

Blood flow and morphofunctional status of gastroduodenal mucosa in different phases of peptic ulcer

AIM: To investigate gastric and duodenal mucosal blood flow (MBF) in different phases of gastric ulcer (GU) and duodenal ulcer (DU) and its relation both to Helicobacter pylori (HP) infection and mucosal disorders. MATERIAL AND METHODS: Upper endoscopy and histological examinations (score of inflammation, atrophy, metaplasy) were performed in 407 patients with DU and 103 with GU. Gastric and duodenal MBF were assessed by the hydrogen gas clearance technique in 102 DU and 95 GU patients. HP was detected by histology. Gastric secretion was measured in the interdigestive period and after stimulation by pentagastrin. RESULTS: Lowering of MBF in gastric antrum and duodenum was observed in DU and GU patients only with score 3 of HP infection. DU healing is accompanied with a decrease of HP value and improvement of mucosal histology. At the same time MBF exhibits a significant rise: in the duodenum (by 45%) at the stage of white scar; in gastric antrum (by 26%) and body (by 40%) at healing stage, but a decrease in white scar. During healing of GU gastric MBF reached maximum in active ulcer but in white scar MBF was significantly lower. MBF at ulcer margin and MBF in ulcer crater was the same (30 ml/min/100 g) with MBF in the region of white scar with enhanced inflammation (score 2.1) before GU relapse. CONCLUSION: Changes of MBF in different phases of ulcer are, in part, determined both by HP and by mucosal morphological disorders. The ratio MBF increase in ulcer healing/MBF reduction in ulcer relapse is the same (30% from optimal) and it is restitution entity. The MBF level of 30 ml/min/100 g was assessed as crucial in ulcerogenesis. Lowering MBF in mucosa with remaining inflammation in the scar region may predict GU relapse.     

Causal relationship between Helicobacter pylori infection and upper gastroduodenal diseases

Helicobacter pylori infection causes chronic gastritis (nonatrophic gastritis), which progresses to atrophic gastritis and intestinal metaplasia over a period of decades. Atrophy may result from inflammation and apoptosis caused by H. pylori infection. H. pylori is an important risk factor for peptic ulcer disease. Duodenitis in the gastric metaplasia of the duodenum, hypergastrinemia, and impaired proximal duodenal mucosal bicarbonate secretion are considered causal factors for duodenal ulcer disease. Low-grade B-cell gastric lymphoma of mucosa-associated lymphoid tissue (MALT) develops in response to H. pylori infection. Studies of Mongolian gerbil model demonstrated that H. pylori had an initiator or promoter effect on gastric carcinogenesis.     

东亚型幽门螺旋杆菌感染与胃癌发生的关系

目的 通过检测各部位慢性胃炎、胃溃疡、胃上皮内瘤变、胃癌幽门螺旋杆菌(Hp)感染情况,探讨河北省消化道肿瘤高发地区Hp感染,特别是东亚型幽门螺旋杆菌(EAS)感染与胃癌发生的关系.方法 依据国际最新悉尼系统分级标准和直观模拟评分法对慢性胃炎进行分级;分别应用Giemsa染色和免疫组织化学法检测贲门、胃体、胃窦3个部位Hp和EAS感染情况,分析Hp感染率、部位分布以及与胃癌发生的关系.结果 总体结果表明,慢性胃炎和胃溃疡中EAS阳性检出率分别为67.0%(138/206)、100.0%(12/12)明显高于上皮内瘤变43.8%(32/73)和胃癌21.7%(13/60)(P<0.05).进一步按病变部位分析贲门、胃体、胃窦和EAS阳性检出率,结果发现同一部位中慢性胃炎、胃溃疡、低级别上皮内瘤变、高级别上皮内瘤变、胃癌Hp和EAS阳性率差异无统计学意义(P>0.05).从慢性胃炎严重程度方面分析,中性粒细胞浸润程度、单核细胞浸润程度、萎缩程度、肠化生程度最严重部位均位于贲门,差异均有统计学意义(P<0.05).Hp密度最高部位位于胃体(P>0.05),但差异无统计学意义.Spearman相关性分析显示,在贲门、胃体、胃窦,Hp密度分别与中性粒细胞浸润程度、单核细胞浸润程度、萎缩程度、肠化生程度呈正相关(P均<0.05).结论 河北省消化道肿瘤高发地区ESA阳性检出率较高,其感染分别与中性粒细胞浸润深度、单核细胞浸润深度、萎缩程度、肠化生程度呈正相关,且在贲门处较易引起严重病变,贲门癌的发生与ESA感染密切相关.     

Feasibility study on eradication of helicobacter pylori北大核心CSCD

Objective To explore the relationship between oral Helicobacter pylori (Hp) infection and gastric Hp infection and examine the possibility of complete eradication of Hp by control of oral Hp infection. Methods Oral Hp was tested in saliva to identify cases of oral Hp infection. A total of 180 patients with gastritis or gastric or duodenal ulcer were randomly assigned to two groups, 90 patients in treatment group and 90 in control group. The diagnosis of gastritis or gastric or duodenal ulcer was made according to positive urease test and pathological examination. The patients in treatment group received triple therapy and brushing teeth with toothpaste containing caries-preventing fluorine material. The patients in control group received triple therapy alone. Hp eradication was detected and compared between groups at various time points to analyze the effect of oral hygiene on eradication of oral and gastric Hp. Results Four weeks after the end of 2-week treatment, positive-to-negative conversion rate of both oral and gastric Hp in treatment group was significantly higher than that in control group (80.0% vs 64.4%, P<0.05). After one-year oral hygiene treatment, the positive-to-negative conversion rate and eradication rate of Hp were significantly higher than those in control group (74.4% vs 40.0%, 93.5% vs 62.1%, all P<0.05). Hp re-infection rate in both oral cavity and stomach was significantly reduced in control group. Conclusions Eradication of Hp by drug therapy is associated with control of oral Hp and oral hygiene. Brushing teeth with toothpaste containing caries-preventing fluorine material in addition to triple drug therapy is beneficial for eradication of Hp and reduced use of antibiotics. © by Editorial Department of Chinese Journal of Infection and Chemotherapy.
