单纯性肥胖症患者外周血ghrelin、obestatin的水平变化及其临床意义

目的 探讨单纯性肥胖症患者餐前、餐后外周血肥胖抑制素（obestatin）水平的变化及其与ghrelin（一种脑肠肽激素）间的关系。方法 采用放射免疫法（RIA）检测16例单纯性肥胖症患者和14例正常对照者餐前1 h及其中各10例餐后2 h外周血ghrelin、obestatin水平;同时采用酶联免疫分析法（ELISA）检测餐前胰岛素水平并监测体质量指数（BMI）、腰臀比、血糖、血脂、白细胞及超敏C反应蛋白。结果 单纯性肥胖症患者餐前外周血ghrelin和obestatin水平均低于正常对照组（均P<0.01）,但ghrelin/obestatin比值却明显高于正常对照组（P<0.01）。单纯性肥胖症组和正常对照组餐后ghrelin/obestatin比值均明显低于其餐前（分别P<0.05,P<0.01）,但两组间差异无统计学意义。相关分析显示餐前ghrelin/obestatin比值与BMI（r=0.54,P<0.01）、腰围（r=0.39,P<0.05）、总胆固醇（r=0.40,P<0.05）和低密度脂蛋白胆固醇（r=0.41,P<0.05）呈正相关;与其它指标间相关性无统计学意义。结论 餐前外周血ghrelin、obestatin间比例失衡可能是单纯性肥胖症的发病机制之一。     

功能性消化不良与社会心理因素的相关性

功能性消化不良发病率居高不下,症状顽固,许多患者都伴有不同程度的焦虑抑郁情绪,严重影响了患者的生活和工作,本文就其最新的一些研究内容做一综述。     

精神心理因素对功能性消化不良患者胃电活动的影响

目的 :探讨在功能性消化不良 (FD)患者中精神心理因素与胃电之间的关系。方法 :对 43例FD患者同时进行精神心理状态测量和体表胃电图检查。结果 :伴焦虑抑郁FD组餐后胃电节律异常的发生率显著高于不伴焦虑抑郁FD组 (39.1 %vs1 0 % )。伴焦虑抑郁FD组发生的胃电节律异常主要是胃电节律过缓和胃电节律紊乱。前者的餐后平均主频不稳定系数显著高于后者 (41 .8± 2 7.4vs32 .6± 2 3 .1 )。结论 :精神心理异常可影响胃电活动 ,产生异常的胃电活动     

高血糖大鼠血浆胃促生长素及肥胖抑制素水平与胃排空的相关性探讨

目的探讨糖尿病初期血浆胃促生长素、肥胖抑制素及其比值（G／O）对胃排空的影响。方法将60只清洁级雄性Wistar大鼠随机分为对照组（NC组）、糖尿病组（DM组）、胰岛素干预组（INS组）各20只。后两组腹腔注射链脲佐菌素（STZ）制备糖尿病模型。INS组每日皮下注射中效胰岛素,另两组皮下注射生理盐水。分别于制模2周、6周,每组随机取半数进行实验,以酚红灌胃法检测胃排空率,酶免疫分析法检测血浆胃促生长素、肥胖抑制素水平。结果2周后,DlVl组较NC组胃排空率升高（P〈0．001）,胃促生长素、肥胖抑制素水平增高（P〈0．01）,G／O值略增高;INS组大鼠胃排空率低于DM组（P〈0．001）,G／O值低于DM组及NC组（P〈0．01）。6周后,DM组较NC组胃排空率升高（P〈0．001）,胃促生长素、肥胖抑制素水平增高（P〈0．01）,G／O值增高（P〈0．05）;INS组较DM组胃排空减慢（P〈0．001）,血浆肥胖抑制素升高（P〈0．05）。结论糖尿病初期血浆G／O升高是胃排空加快的可能原因之一,外源性补充胰岛素对肥胖抑制素水平的影响可能与调节胃排空有一定关系。     

功能性消化不良患者血浆ghrelin变化及其与胃排空的关系

背景：ghrelin已被证实具有促进胃肠动力的作用,而胃肠动力障碍是功能性消化不良（FD）的重要发病机制,目前关于ghrelin与FD关系的临床研究较少。目的：探讨FD患者血浆ghrelin变化及其与临床症状和胃排空的关系。方法：纳人40例FD患者．其中餐后不适综合征（PDS）25例,上腹痛综合征（EPS）15例,并以20名健康者作为对照。评估临床症状评分,以实时B超检测胃半排空时间（GET1/2）,ELISA法检测血浆酰基化ghrelin水平,并分析血浆酰基化ghrelin水平与临床症状评分和GET1的关系。结果：与对照组相比,PDS组GET1/2和血浆酰基化ghrelin水平明显升高（P〈0．05）,而EPS组无明显差异（P〉0．05）。FD患者餐后饱胀与早饱症状评分之和与GET1/2呈正相关（r=0．33,P=0．04）,但与血浆酰基化ghrelin水平无关。PDS组和EPS组患者血浆酰基化ghrelin水平与临床症状评分均无关。PDS组患者血浆酰基化ghrelin水平与GET1/2呈正相关（r=0．43,P=0．033）,而EPS组中两者无关。结论：PDS患者血浆酰基化ghrelin水平明显升高,并与胃排空功能相关,提示ghrelin在FD的发生过程中发挥一定的作用。     

不同亚型功能性消化不良并发抑郁、焦虑症状情况及对患者生活质量的影响

目的观察功能性消化不良(functional dyspepsia,FD)的3种亚型餐后不适综合征(postprandial distress syndrome,PDS)和上腹疼痛综合征(epigastric painsyndrome,EPS)以及PDS重叠EPS患者的抑郁、焦虑症状情况及对生活质量(qualityoflife,QOL)的影响。方法 144例FD患者分成3组,采用综合医院焦虑,抑郁量表(hospital anxiety and depressive scale,HADS)及SF-36评分。结果 PDS组抑郁、焦虑及抑郁合并焦虑的患病率为18.75%、29.17%、4.17%,EPS组为8.33%、14.58%、2.08%,EPS合并PDS组为27.08%、45.83%,10.42%;3组SF-36评分有极显著性差异(P<0.01)。结论不同亚型FD有不同的精神心理因素影响,PDS与PDS重叠EPS患者抑郁、焦虑症状及生活质量影响比EPS患者严重,特别是焦虑,尤以PDS重叠EPS者为甚。     

联合检测FT3、Ghrelin、obestatin水平及其与冠心病的相关性

目的探讨联合检测血清游离三碘甲状腺原氨酸(serum free triiodothyronine,FT3)、胃饥饿素(Ghrelin)、肥胖抑制素(obestatin)水平及其与冠心病的相关性。方法选择在本院就诊的可疑冠心病患者230例,根据冠状动脉造影结果将患者分为冠心病组和非冠心病组,在造影前采集所有研究对象的肘部静脉血,检测甲状腺激素、Ghrelin和obestatin水平,观察其与冠心病之间的关系。结果冠心病组的FT3水平Ghrelin/obestatin比值较非冠心病组低,差异有统计学意义(P 0. 05)。FT3、Ghrelin/obestatin与冠心病均呈负相关(r=-0. 49、-0. 77,P 0. 01)。非条件Logistic回归分析结果显示FT3、Ghrelin/obestatin是冠心病的独立危险因素(P 0. 05);使用ROC曲线评价FT3、Ghrelin/obestatin对冠心病的诊断价值,结果显示FT3单独检测的曲线下面积为0. 76,Ghrelin/obestatin单独检测的曲线下面积为0. 78,联合两者检测的曲线下面积为0. 91,诊断价值较高,敏感度、特异度分别为89. 89%、70. 00%。结论FT3、Ghrelin、obestatin水平与冠心病有较大关系,联合检测可提高冠心病的诊断率。

目的了解中国大城市消化内科肠易激综合征和功能性消化不良患者抑郁、焦虑症状患病率及既往诊治情况。方法采用现况研究方法，于2004年6月1日到9月1日在北京、广州和成都6家综合性医院的消化内科连续收集肠易激综合征303例和功能性消化不良患者305例。由经培训的调查员用统一的调查表进行面对面调查，同时使用综合医院焦虑抑郁量表（HAD）、Hamilton焦虑量袭和Hamilton抑郁量表进行心理测评。结果肠易激综合征和功能性消化不良的抑郁、焦虑症状患病率分别为24．8％和23．6％。在具有抑郁、焦虑症状的患者中，两类患者抑郁和（或）焦虑障碍的患病率分别为69．6％和68．7％；在具有抑郁、焦虑症状的非首诊患者中，两类患者既往抑郁障碍诊断史和抗抑郁治疗的比例均低于12％，而既往焦虑障碍诊断史和抗焦虑治疗的比例则更低于8％。肠易激综合征女性患者的抑郁症状患病率显著高于男性（17．0％比8．7％；χ^2=4．432，P=0．035），其抑郁障碍、焦虑障碍、抑郁合并焦虑障碍以及抑郁、焦虑障碍的患病率均高于男性（52．6％比25，0％，χ^2=4．612，P=0．032；79．5％比53．8％，χ^2=4．815，P=0．028；51．4％比21．7％，F=5．112，P=0．024；78．6％比55．6％，χ^2=4．112，P=0．043）。结论中日大城市综合医院肠易激综合征和功能性消化不良门诊患者具有较高的抑郁、焦虑症状和抑郁、焦虑障碍患病率，且既往诊治率较低，这一现状值得卫生管理部门和临床医务人员关注。     

不同亚型功能性消化不良患者血清CRF水平及其与焦虑/抑郁的关系

[目的]评估不同亚型功能性消化不良(functional dyspepsia,FD)患者血清促肾上腺皮质激素释放因子(corticotrophin releasing factor,CRF)水平差异及其与焦虑/抑郁的关系。[方法]根据罗马Ⅲ诊断标准,将66例FD患者分为餐后不适综合征(PDS)组(22例)、上腹痛综合征(EPS)组(22例)和PDS重叠EPS组(22例),并设立正常对照组(30例)。收集病例资料,根据FD症状量化积分评定症状严重程度,采用汉密尔顿焦虑/抑郁量表(HAMA/HAMD)评估FD患者各组焦虑/抑郁状态。采用竞争酶联免疫吸附(ELISA)试验检测血清CRF浓度,并比较各组间差异。[结果]FD患者各组血清CRF平均浓度均高于正常对照组(P0.01),但FD患者各组间差异无统计学意义(P0.05);FD患者各组中伴焦虑/抑郁者血清CRF平均浓度均高于不伴焦虑/抑郁者(P0.05);CRF浓度与FD患者FD症状量化积分或HAMA/HAMD评分均呈正相关性(P0.05)。[结论]FD患者血清CRF水平较正常人增高,血清CRF浓度的增加与FD患者焦虑/抑郁行为有关,CRF可能参与FD的发生、发展。     

Plasma levels of acylated ghrelin in patients with functional dyspepsia

AIM: To investigate the relationship between plasma acylated ghrelin levels and the pathophysiology of functional dyspepsia.METHODS: Twenty-two female patients with functional dyspepsia and twelve healthy volunteers were recruited for the study. The functional dyspepsia patients were each diagnosed based on the Rome III criteria. Eligible patients completed a questionnaire concerning the severity of 10 symptoms. Plasma acylated ghrelin levels before and after a meal were determined in the study participants using a commercial human acylated enzyme immunoassay kit; electrogastrograms were performed for 50 min before and after a standardized 10-min meal containing 265 kcal.RESULTS: There were no significant differences in plasma acylated ghrelin levels between healthy volunteers and patients with functional dyspepsia. However, in patients with functional dyspepsia, there was a negative correlation between fasting plasma acylated ghrelin levels and the sum score of epigastric pain (r = -0.427, P = 0.047) and a positive correlation between the postprandial/fasting plasma acylated ghrelin ratio and the sum score of early satiety (r = 0.428, P =0.047). Additionally, there was a negative correlation between fasting acylated ghrelin plasma levels and fasting normogastria (%) (r = -0.522, P = 0.013). Interestingly, two functional dyspepsia patients showed paradoxically elevated plasma acylated ghrelin levels after the meal.CONCLUSION: Abnormal plasma acylated ghrelin levels before or after a meal may be related to several of the dyspeptic symptoms seen in patients with functional dyspepsia.

目的研究功能性消化不良运动障碍亚型患者胃固体排空功能与其临床症状的关系.方法对有4周以上腹胀、恶心、食欲减退等症状的患者进行症状评分,症状总积分≥9分,早饱、上腹胀至少具备一项且≥2分者,行胃镜、B超等有关检查,排除器质性病变后诊断为功能性消化不良运动障碍亚型.确诊患者服用标准试餐加固体小钡条,餐后5h透视确定胃内钡条排空情况;同时所观察患者服用西沙必利每次5mg、每日3次治疗,并于治疗2周及4周末复查.结果功能性消化不良运动障碍亚型中67.5%的患者有胃排空异常,女性与男性无显著性差异(P>0.05).治疗前胃排空正常者的症状积分为10.00±1.41,,胃排空异常者为11.70±2.28,二者相比无明显差异(P>0.05);治疗2周及4周后,胃排空正常者的症状积分分别为4.90±2.45、2.10±1.19,胃排空异常者则分别为7.00±3.12、4.20±2.39,与治疗前相比二者的症状总积分均明显降低,而且前者比后者的症状积分更低(P<0.05).治疗前患者的症状积分虽与胃内钡潴留无明显相关(r=0.078,P>0.05),但治疗后二者却有一定的相关性(r=0.47,P<0.05).结论功能性消化不良患者有明显的胃排空延迟;胃排空延迟确与运动障碍样症状有关,但与症状的严重程度无关;西沙必利治疗可使所有患者的症状及部分患者的胃排空不同程度改善.     

Gastric metaplasia of the duodenum: in vivo diagnosis by endomicroscopy and its relationship with functional dyspepsia

Background and Aim: Gastric metaplasia (GM) of the duodenum is difficult to assess because of its patchy distribution, and the role of GM in functional dyspepsia (FD) is not clear. The aims of this study were to determine if endomicroscopy could identify GM of the duodenum and whether GM has associations with FD. Methods: A series of 51 patients with FD and 25 asymptomatic controls were enrolled. Confocal laser endomicroscopy was performed to evaluate villi changes in vivo. Targeted biopsy specimens were then compared with histopathological results. Results: The accuracy of the endomicroscopy diagnosis of GM during endoscopy was 92.8%, and the sensitivity, specificity, and positive and negative predictive values were 86.2%, 97.4%, 89.3%, and 96.6%, respectively. The mean κ‐value for interobserver agreement was 0.89. GM in the duodenal bulb was more frequent in patients with FD than in the controls (33.3% vs 12%, P < 0.05), especially in patients with epigastric pain syndrome (47.6% vs 12%, P < 0.01). Conclusions: Endomicroscopy is useful for identifying GM, and GM might be related to FD. These findings could have potential applicability for duodenal screening, and suggest a possible targeting therapy in FD.

Prevalence of functional dyspepsia and its relationship with Helicobacter pylori infection in a Japanese population

AIM: To investigate the prevalence of functional dyspepsia and Helicobacter pylori infection and their relationship in a Japanese population. METHODS: Two thousand five hundred people who visited Shimane Institute of Health Science for their annual medical check-up from September 1998 to August 1999 were prospectively enrolled in the study. After routine medical examination, including an upper gastrointestinal study and an ultrasonographic examination, all subjects were asked standard questions to check for the presence of any symptoms that suggested dyspepsia. Helicobacter pylori infection was determined by using a serum IgG antibody concentration with an ELISA. RESULTS: Of the 2,500 persons investigated, 2,263 showed no abnormal finding in any medical examination. The presence or absence of symptoms and H. pylori infection was investigated in these 2,263 cases. Of these, 201 people (8.9%) experienced nausea, fullness and/or early satiety and were diagnosed as having dysmotility-like dyspepsia, while 118 people (5.2%) experienced pain localized to the epigastrium and were diagnosed as having ulcer-like dyspepsia. The frequency of these symptoms had a tendency to decline with age, although this was not statistically significant. In contrast, the rate of H. pylori infection increased with age. There was no significant relationship between H. pylori infection and any type of functional dyspepsia. CONCLUSIONS: Helicobacter pylori infection does not influence the prevalence of the dysmotility-like and ulcer-like dyspeptic symptoms.
