慢性胃炎中医辨证与血浆中胃泌素及生长抑素变化的研究   总被引:2,自引:0,他引:2  
采用放射免疫法检测了13例肝不和型、10例脾胃虚寒型慢性浅表性胃炎患者和10名健康志愿者餐前、餐后30、120min血浆中胃泌素和生长抑素(SS)的浓度。结果:脾胃虚寒组与正常对照组餐前、餐后Gas水平有相似的变化,餐后30min3组血浆中Cas浓度均明显增高,肝胃不和组餐前Gas水平较其余两组高,但无显著性差异;餐后30minGas水平3组相近,但餐后120min时,肝胃不和组Gas水平仍维持在  相似文献

以提高中医诊断客观化,探讨胃脘痛证型本质为目的,对96例慢性胃脘痛证型与胃电图的关系进行了研究,结果发现:脾胃虚寒证的胃电幅值在餐前、餐后均低于正常人组和其它3个实证组,具有统计学意义(P<0.05),而3个实证组及正常人组间两两比较,胃电幅值和频率餐前、餐后无明显差异(P>0.05)、96例中幽门螺杆菌感染阳性组胃电波餐前、餐后明显高于幽门螺杆菌阴性组和正常人组,具有统计学意义(P<0.05)。结果表明,胃电减弱是脾胃虚寒证的病理基础之一。幽门螺杆菌对胃电参数有所影响,是导致胃脘痛的病因之一。  相似文献

目的:观察肝胃不和型功能消化不良(FD)大鼠胃和十二指肠运动功能、血浆胃动素(MOT)含量和胃肠壁P物质(SP)的表达,探讨肝胃不和型FD的发病机制及中药情志舒治疗肝胃不和型FD的可能机制。方法:将64只大鼠随机分为对照组,模型组,多潘立酮组及情志舒组;应力传感器记录大鼠胃和十二指肠移行性复合运动(MMC);放免法测定大鼠血浆MOT含量;PAP免疫组化法观察SP在胃窦壁和十二指肠壁的表达情况。结果:与模型组比较,情志舒组MMC周期缩短,Ⅲ相延长,频率加快,幅度高,MMCⅢ相发生率增加,胃和十二指肠协调收缩率显著增加,MMCⅢ相时血浆MOT含量显著增加;胃肠壁SP免疫阳性产物表达也明显增强(P<0.01,<0.05)。结论:胃肠MMCⅢ相异常,胃肠协调运动障碍可能是肝胃不和型FD的发病机制之一,肝胃不和型FD大鼠血浆MOT含量的降低和胃肠壁SP表达的降低可能是肝胃不和型FD发病的神经生学基础,情志舒可能增加MMCⅢ相血浆MOT的释放和胃肠壁SP的表达,从而改善胃肠运动功能来治疗肝胃不和型FD。  相似文献

目的探讨功能性消化不良(FD)餐后不适综合征(PDS)患者液体食物胃中分布情况,了解其胃动力障碍发病机制。方法应用超声诊断仪对52例 PDS 患者和18名健康志愿者进行胃排空检查,在空腹,最大饱腹感,餐后30、60、90和120 min 分别计算近端胃与远端胃面积和容积,近端胃与远端胃面积比率和容积比率,近端胃和远端胃排空率。统计学处理采用 t 检验、卡方检验。结果空腹、餐后120 min时,PDS 组近端胃容积分别为(9.06±7.88)和(24.72±24.02)cm3,健康对照组分别为(5.96±2.13)和(19.48±12.32)cm3,差异均有统计学意义(t=-1.637、-0.875,P 均<0.05)。在最大饱腹感时,PDS 组近端胃与远端胃面积比率为1.63±0.42,健康对照组为2.33±0.63,差异有统计学意义(t=5.044,P <0.05)。在空腹时,PDS 组近端胃与远端胃容积比率为0.60±0.38,健康对照组为0.46±0.19,而在最大饱腹感时,PDS 组为0.91±0.27,健康对照组为1.30±0.48,差异有统计意义(t=-1.505、3.970,P 均<0.05)。在餐后30、90 min 时,PDS 组近端胃排空率分别为(28.10±25.03)%和(68.80±16.14)%,健康对照组分别为(34.97±14.41)%和(75.86±9.86)%,差异有统计学意义(t =1.087、1.718,P <0.05);两组远端胃排空率差异均无统计学意义(P 均>0.05)。结论PDS 患者液体食物分布在最大饱腹感时远端胃容积大于近端胃容积,这可能是导致其近端胃排空率下降的原因,近端胃对PDS 患者胃动力影响较大。  相似文献

为了探讨糖尿病脂蛋白异常血症的发生机理,研究了53例糖耐量异常者(糖耐量异常组)和27例糖耐量正常者(对照组)的血脂和血浆载脂蛋白水平,以及进行了葡萄糖耐量试验和胰岛素释放试验。结果发现,糖耐量异常组空腹及口服葡萄糖后60min血糖和血浆胰岛素水平与对照组无显著差异(P>0.05),而口服葡萄糖后120min血糖(P<0.05)、血浆胰岛素水平(P<0.01)和口服葡萄糖后180min血糖(P<0.01)、血浆胰岛素水平(P<0.05)均比对照组显著升高。糖耐量异常组血浆甘油三酯和总胆固醇显著升高(P<0.01和P<0.05),同时伴有一定程度的低密度脂蛋白胆固醇升高和高密度脂蛋白胆固醇降低,以及载脂蛋白CⅡ、CⅢ及E显著增高(P<0.01、P<0.001和P<0.005),这些血脂改变与糖尿病脂蛋白异常血症类似。此结果表明,胰岛素抵抗、高胰岛素血症在糖尿病脂蛋白异常血症的发生中起着重要的作用。同时也提示对一些空腹血糖正常,糖耐量异常,但还没有临床诊断为糖尿病患者,应进行常规血脂检查,筛选出脂蛋白异常者,并采取相应的措施予以纠正。  相似文献

高血压和糖尿病患者餐后状态血压及脉压变化特征的研究   总被引:16,自引:0,他引:16  
目的:研究高血压病、2型糖尿病和高血压合并糖尿病患餐后状态血压和脉压变化的特点,探讨其可能机制。方法:328例住院患,分为高血压病组(EH组,116例)、2型糖尿病组(DM组,100例)和高血压伴糖尿病组(EH+DM组,112例),行24小时态血压(ABPM)检测,其中30例患再行有创桡动脉压测量,观察餐前和餐后收缩压(SBP)、舒张压(DBP)和脉压(PP)变化特点。结果:EH组餐后SBP和DBP升高(P<0.01),而以SBP升高更明显,列后PP升高(P<0.01)。DM组SBP和DBP均下降(P<0.05),但餐后PP无明显变化(P>0.05)。结论:EH+DM组和DM组患各餐后SBP和DBP降低,其中EH+DM组餐后DBP下降较显,餐后PP也增大。而H组患餐后SBP和DBP升高,而以SBP升高较显,餐后PP也增大。DM组患各餐后SBP和DBP降低幅度相似,其餐后PP无明显变化。三组患餐后血压和脉压变化各有其特征,其机制可能与大动脉硬化程度、外周血管舒缩功能及糖尿病自主神经病变等因素有关。  相似文献

BackgroundThe systemic inflammatory response seen after surgery seems to be related to postoperative complications. A reduction of the inflammatory response through minimally invasive surgery might therefore be the mechanism via which postoperative outcome could be improved. The aim of this study was to investigate if postoperative inflammatory markers differed between laparoscopic (LPD) and open pancreatoduodenectomy (OPD) and if there was a relationship between inflammatory markers and the occurrence of postoperative complications.MethodsA side study of the multicenter randomized controlled LEOPARD-2 trial comparing LPD to OPD was performed. Area under the curve (AUC) for plasma inflammatory markers, including interleukin (IL-) 6, IL-8 and C reactive protein (CRP) levels, were determined during the first 96 postoperative hours and compared between LPD and OPD, Clavien-Dindo ≥ III complications, and postoperative pancreatic fistula (POPF) grade B/C.ResultsOverall, 38 patients were included (18 LPD and 20 OPD). The median AUC of IL-6 was 627 (195–1378) after LPD vs. 338 (175–694)pg/mL after OPD, (p = 0.114). The AUC of IL-8 and CRP were comparable. IL-6 levels were higher in patients with a Clavien-Dindo ≥ III complication (634[309–1489] vs. 297 [171–680], p = 0.034) and POPF grade B/C (994 [534–3265] vs. 334 [173–704], p = 0.003). In patients with a POPF grade B/C, IL-6 levels tended to be higher after LPD, as compared to OPD (3533[IQR 1133–3533] vs. 715[IQR 39–1658], p = 0.053).ConclusionLPD, as compared to OPD, did not reduce the postoperative inflammatory response. IL-6 levels were associated with postoperative complications and pancreatic fistula.  相似文献

Background

Frozen elephant trunk (FET) surgery offers a new alternative in the management of complex thoracic aortic aneurysms and dissections. We performed a systematic review and meta-analysis of comparator observational studies evaluating the efficacy of FET compared with conventional aortic arch surgery, primarily focusing on mortality and stroke as well as the secondary outcomes of spinal cord ischemia, major bleeding, and operative time.

Methods

We searched MEDLINE, EMBASE, PubMed, and the Cochrane Library for trials and studies comparing the FET technique with conventional surgery in patients with aortic aneurysms or dissections, or both. The overall quality of evidence was low, as assessed by Grading of Recommendations, Assessment, Development, and Evaluation, based primarily on the risk of bias secondary to study design, plausible confounding, and imprecision.

Results

Meta-analysis revealed a significant reduction in mortality (12 studies, 1803 patients: odds ratio [OR], 0.55; 95% CI, 0.39-0.78) and a nonsignificant reduction in stroke (12 studies, 1803 patients: OR, 0.78; 95% CI, 0.52-1.15) favouring FET; however, FET was associated with a significant increase in spinal cord ischemia (9 studies, 1476 patients: OR, 2.20; 95% CI, 1.10-4.37). No significant differences between groups were observed regarding major bleeding, cardiopulmonary bypass time, or cross-clamp time.

Conclusions

Current evidence suggests that FET surgery is associated with lower mortality in patients with thoracic aneurysmal disease and dissections, without a significant increase in stroke, bleeding, or operative times. However, the risk of spinal cord ischemia is increased in patients who undergo FET. A well-powered randomized trial is needed to evaluate this evolving field.  相似文献

BackgroundThe value of open and minimally invasive liver resection for symptomatic solid benign liver tumours (BLT) such as hepatocellular adenoma, focal nodular hyperplasia and haemangioma is being debated. A systematic review on symptom relief, quality of life (QoL) and surgical outcome after both open and minimally invasive surgery for solid BLT is currently lacking.MethodsA systematic search in PubMed and EMBASE was performed according to the PRISMA guidelines (January 1985–April 2018). Articles reporting pre-and postoperative symptoms or QoL in patients undergoing open or minimally surgery for BLT were evaluated. Methodological quality was assessed using the MINORS tool.ResultsForty-two studies were included with 4061 patients undergoing surgery for BLT, 3536 (87%) open and 525 (13%) laparoscopic resections. Randomized and propensity-matched studies were lacking. Symptoms were the indication for resection in 56% of the patients. After a weighted mean of 28.5 months follow-up after surgery, symptoms were relieved in 82% of symptomatic patients. Validated QoL tools were used in eight studies, of which two found significant better QoL scores following laparoscopic compared to open surgery.DiscussionResection of symptomatic BLT seems safe and relieves symptoms in the vast majority of selected patients. Comparative studies are needed before more firm conclusions can be drawn.  相似文献
