门静脉高压性胃病的研究进展

门静脉高压性胃病(PHG)是一种内镜下胃黏膜呈特征性马赛克样改变的疾病,其组织学上无明显炎性改变。PHG是上消化道出血的重要因素之一,超过65%的肝硬化门静脉高压症患者会发展为PHG。目前PHG的发病机制尚未完全清楚。PHG临床主要表现为消化道出血等症状,其诊断主要依靠内镜和组织学,治疗主要针对降低门静脉压力。     

门脉高压症所致门脉高压性胃病119例分析

门脉高压患者由于全身和内脏的循环动力学增高，门静脉血流量增加，而且出现门脉压力增高并可引起整个消化道粘膜病变。而门脉高压性胃病(PHG)是门脉高压症患者上消化道出血的常见原因之一。本文就内镜确诊的119例PHG患者进行了临床及内镜分析，现报告如下。     

门脉高压性胃病的研究

肝硬化患者发生上消化道出血，常常被认为是食管胃底静脉曲张破裂出血所致。随着急诊内镜的广泛开展应用，发现部分患者的出血是由于胃黏膜严重糜烂坏死出血所致。此病又称为门脉高压性胃黏膜病变（PHG）。门脉高压性胃病是指门脉高压症伴发的胃黏膜病变，主要发生于肝硬化门脉高压症患者，是肝硬化门脉高压症的常见并发症。1984年Sarfeh等提出PHG与非PHG在形态、功能、治疗上都有不同，因其病理组织学上炎性改变依据不足，可称其为门脉高压性胃病，逐渐引起人们重视。PHG常与食管静脉曲张同时存在，而PHG出血可占门脉高压消化道出血的10％-60％”。     

肝硬化门脉高压性胃病临床分析

正门静脉高压性胃病(portal hypertension gastropa-thy,PHG)是指由门脉高压引起的胃黏膜非炎性病变,是门静脉高压症患者除食管胃底静脉曲张破裂外另一重要出血因素[1]。为了探讨肝硬化PHG与食管胃底静脉曲张程度、上消化道出血、门静脉宽度及肝功能Child-Pugh分级的关系,我们于2008年1~6月回顾性分析了我院126例肝硬化患者的胃镜及临床资料,报告如下。对象与方法1.一般资料:本     

门静脉高压性胃病的研究进展

门静脉高压性胃病(PHG)是一种内镜下胃粘膜呈特征性马赛克(mosaic)样改变的疾病,其组织学上无明显炎症性改变,即或有炎症也很轻,和粘膜损害的程度不符合,在疾病概念上与急性胃炎(出血性或糜烂性)不同.目前,PHG的发病机制尚未完全清楚,临床上多表现为慢性隐匿性出血,出血量与PHG的持续时间及病变范围和严重程度有关,在肝硬化上消化道出血病因中,PHG仅次于食管-胃底静脉曲张破裂,而在重度肝功能不全患者及重度PHG患者中,则上升为第一位出血因素,故PHG越来越引起人们的重视.本文将重点对PHG的研究进展作一综述.     

门静脉高压性胃病与幽门螺杆菌感染的关系

目的 探讨门静脉高压性胃病(portal hypertensive gastropathy,PHG)的致病因素,尤其是与幽门螺杆菌(helicobacter pylori,HP)感染的关系.方法 对已确诊的101例住院肝硬化患者均进行胃镜和彩色多普勒超声(彩超)检查,同时进行HP检查,分析PHG与食管胃底静脉曲张程度、肝硬化病因、HP感染的关系.结果 PHG的发生率为37.6%,PHG的发生率及其严重程度与食管胃底静脉曲张程度有关,在肝功能Child-PughA、B、C级之间,不同病因肝硬化之间,是否感染HP之间,PHG的发生率差异均无统计学意义(均为P＞0.05).肝硬化病人的慢性活动性胃炎与HP阳性有关(P＜0.01),而与门静脉高压关系不大.结论 PHG的发生与肝硬化的病因、肝功能分级和HP感染关系不明显,与食管静脉曲张程度有关.肝硬化病人的慢性活动性胃炎可能与HP感染有关.     

130例肝硬化门脉高压症患者胃镜检查结果分析

目的分析各种原因引起的门脉高压症患者胃粘膜特点。方法130例研究对象共分为3组:A组47例,为乙肝肝硬化;B组42例,为酒精性肝硬化;C组41例,为脂肪性肝硬化。所有研究对象于入院后3天内行电子胃镜检查,观察门静脉高压性胃病(PHG)及急性胃粘膜病变(AGML)的检出情况。结果A组、B组、C组3组患者PHG、AGML检出例数分别为36例(76.60%)、14例(29.79%),30例(71.43%)、35例(83.33%),32例(78.05%)、13例(31.71%);3组患者其PHG检出例数之间差异均无显著性(P>0.05),但无论A组或是C组其AGML检出例数与B组相比,差异均有高度显著性(P<0.01)。结论肝硬化门脉高压患者易合并PHG及AGML,PHG及AGML可能与慢性肝病基础有关,但酒精性肝硬化以AGML病变为多见,其余两种均以PHG为多见。     

门静脉高压性胃病诊断及治疗策略

目的探讨门静脉高压性胃病(PHG)的临床特点，为其诊断及治疗提供理论依据。方法对40例门静脉高压性胃病患者临床资料进行回顾性分析。结果PHG的程度与食管静脉曲张程度及肝功能损害程度间存在一定的依从关系。PHG合并出血的治疗以降低门静脉压力为主。结论门静脉高压、肝功能受损与PHG形成有关。首选降低门静脉压力的药物防治PHG出血。

Value of D-Dimers in patients with acute aortic dissection

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P ＜ 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (＞0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P ＜0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P ＜ 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.     

Research of combined liver-kidney transplantation model in rats

Objective： To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods： SD rats served as both donors and recipients. 4℃ sodium lactate Ringer＇s was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava （IVC） inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results： Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion： This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.     

BLOOD PRESSURE CHANGE WITH AGE IN SALT-SENSITIVE TEENAGERS

Objective To observe blood pressure change with age in salt-sensitive teenagers whose salt sensitivity were determined by repeated testing.Methods Salt sensitivity was determined through intravenous infusion of normal saline combined with volume-depletion by oral diuretic furosemide in 55 teenagers. After five years, salt sensitivity was re-examined and subject blood pressure was followed up. Blood pressure changes in salt-sensitive teenagers were compared to that of non-salt sensitive teenagers over five years.Results After 5 years, the repetition rate of salt sensitivity determined by intravenous saline loading is 92.7%. In teenagers with salt sensitivity on the baseline, both the systolic blood pressure increments and increment rates were much higher than non-salt sensitive teenagers (12.7±12.1 mmHg vs. 2.8±5.2 mmHg, P＜ 0.01; 12.2%± 12.0% vs. 2.5% ±4.4%, P＜ 0.001,respectively). There was a similar trend for diastolic blood pressure (8.4 ± 6.4 mmHg vs. 3.7 ± 6.4 mmHg, P = 0.052; 13.2% ±10.6 % vs. 6.8%± 10.1%, P = 0.053, respectively).Conclusions Salt sensitivity determined by intravenous saline loading showed good reproducibility. Blood pressure increments with age were much higher in salt-sensitive teenagers than non-salt sensitive teenagers, especially in terms of systolic blood pressure.     

Development on Adjustable Calibration Marker for Shock Wave Focus

Shock wave lithotripsy （SWL） is a treatment of choice for upper urinary stones. However, this procedure is inappropriate for obese patients because the focus is often unable to reach the target owing to the limited focal distance in shock wave source. Although treating such patients in a blast path may increase the application length of shock wave source, it＇s difficult to find this path on the lithotripter monitor. For this reason, we invented an adjustable calibration marker in order to set an effective focus in the shock wave hath.     

Study on the TCM Pathogenesis of Angiopathic Complications of Type II Diabetes

Excess production of reactive oxygen species(ROS)of mitochondrion mediated by hyperglycemia is the common pathogenesis of angiopathic complications of diabetes.TCM holds that the damp from the dysfunction of spleen.kidney and liver is the causative factor of complications of diabetes.This is similar to the mechanism of Ros resulting in angiopathic complications of diabetes.When the angiopathic complications of type II diabetes mellitus(T2DM)are difierentiated as caused by turbid damp in TCM can be explained as ROS.Since the obstruction of pathogenic damp in channels and collaterals is said to be the main pathogenesis,the treating principle should be dissolving the damp to remove the obstruction.     

Leptin, Ghrelin and TNF-α before and after Hypo-caloric Traditional Chinese Diet and Auricular Acupuncture

INTRODUCTION Obesity is a complex emergent problem, which can be possibly solved not only by the diet but also by the life style and promotion of a constant physical exercise. 1, 2 No doubt careful attentions must be given to the nutritional condition of obese people, the dietary habits, the somatic build (i.e. distribution of fat mass) and the organic functions linked to formation of the fat mass. All the parameters should be constantly monitored before, during and after a diet treatment. 3, 4, 5

CLINICAL SIGNIFICANCE OF SERUM CYTOKINES IL-1β,sIL-2R,IL-6,TNF-α,AND IFN-v IN ACUTE CORONARY SYNDROME

Objectives To explore serum cytokines levels (including IL-1 β, sIL-2R, IL-6, TNF-α, and IFN-v) and their significance in patients with acute coronary syndrome (ACS) and the subsequent follow-ups, with attempt to estimate the role of various serum inflammatory markers in the diagnosis and assessment of ACS.Methods The study population include 40 patients with acute myocardial infarction (AMI), 40 patients with unstable angina pectoris (UAP), and 40 controls. Among the 80 patients, 60 patients attended a follow up 4 months later. Serum inflammatory markers including IL-1 β, sIL-2R, IL-6, TNF-α, and IFN-v were measured by enzyme linked immunosorbent assay.Results Serum IL- 1 β, sIL-2R, IL-6, TNF-α were significantly higher in AMI group or UAP group compared to the control group and became significantly lower 4 months later in the follow-up patients. Serum levels of IFN-v shows no significant difference between AMI group or UAP group and controls, also showing no significant change when measured in follow up patients. There was no correlation between serum creatine kinase-MB isoenzyme levels and serum inflammatory markers either in UAP or AMI group. Furthermore, when divided into two subgroups using Wagner's QRS scoring system in the AMI group, there is no difference of each serum inflammatory marker between ≤ 6 scores group and ＞ 6 scores group.Conclusion Serum levels of certain inflammatory markers may have some diagnostic value for ACS, and can be a useful marker reflecting disease stability.
