支气管哮喘(bronchial astima,以下简称哮喘)是由多种细胞(如:嗜酸性粒细胞、T细胞、肥大细胞、中性粒细胞等)和细胞组分参与的气道慢性炎症性疾病[1],以气道慢性嗜酸性粒细胞炎症、气道高反应性和不可逆性气道重塑(airwayremodeling)为特点[2]。气道重塑是由Huber和Koessler在1922年首先提出的。目前认为:气道重塑是指气道在慢性炎症刺激下所发生的气道壁结构变化,包括气道平滑肌细胞增生和肥大,细胞外基质(胶原)沉积、基底膜增厚,炎症细胞浸润和腺体增生肥大,是哮喘发病机制的一个重要环节和哮喘气道病理改变的重要基础[3,4]。进一步的…  相似文献

痰嗜酸粒细胞(EOS)作为支气管哮喘的炎症效应细胞,与哮喘患者气道炎症、气道重构密切相关,在哮喘发病机制中起重要作用。痰EOS作为评价哮喘治疗效果的重要指标,具有评价治疗反应性、预测哮喘再次发作风险以及提示预后等作用。连续动态监测痰EOS计数,有助于评估哮喘治疗的反应性和充分性,将其作为气道炎症标志物的哮喘管理模式在哮喘临床管理中具有一定的参考价值。由于不同哮喘患者存在气道炎症表型差异,明确表型并分别给予精准治疗方案,可优化哮喘治疗的管理方法。目前,抗白细胞介素-5治疗支气管哮喘已显示出一定的功效,针对哮喘气道EOS炎症靶向药物的治疗已得到肯定,靶向药物为未来哮喘的治疗提供了更多可能性。  相似文献

肺表面活性物质对哮喘豚鼠肺血管通透性的作用   总被引:2,自引:1,他引:1  
目前认为哮喘是气道慢性炎症性疾病 ,其临床特征是气道高反应。当触发因素存在时 ,可激活多种炎症细胞和释放系列炎症介质 ,引起气道平滑肌痉挛 ,致哮喘突然发作。有报道认为炎症介质或酸中毒等会引起细胞膜通透性变化。对哮喘的进一步研究发现 ,哮喘时存在肺表面活性物质 (PS)功能不良 ,并发现肺泡 型细胞中板层体空泡化 ,而外源性 PS能够预防 [1 ] 和治疗实验性哮喘 [2 ] 。本研究旨在探讨应用 PS预防和治疗哮喘时对肺血管通透性的作用。1 材料和方法1.1 动物及分组 雄性豚鼠 5 0只 ,体质量 2 5 0~ 30 0 g(上海计划生育研究所动物…  相似文献

近年来 ,通过纤维支气管镜下组织活检和支气管肺泡灌洗液细胞学的研究 ,强调了由各种因素造成的气道变应性炎症 ,气道粘膜和粘膜下层炎症细胞 ,尤其是嗜酸性粒细胞为主的气道慢性炎症是支气管哮喘的病理基础[1] 。针对哮喘发病的炎症机制 ,提出了预防和控制气道炎症应是哮喘的第一线治疗措施这一全新观念 [2 ] 。这一观念的出现使临床上摒弃了已沿用多年、经典的以支气管解痉剂为主的治疗原则。目前已知的具有抗气道炎症的药物主要包括 :皮质类固醇、肥大细胞膜稳定剂、新型抗组胺药、长效β2受体激动剂、炎症介质拮抗剂以及其它一些可能有…  相似文献

咳嗽变异性哮喘(coughvariantasthma,CVA)是慢性咳嗽的首要病因。2015年《咳嗽的诊断与治疗指南》指出,如咳嗽持续时间>8周应首先考虑CVA [1]。 CVA在儿童中特别常见[2],其主要表现为刺激性干咳,通常咳嗽比较剧烈,夜间咳嗽为其重要特征;感冒、冷空气、灰尘、油烟等容易诱发或加重咳嗽。CVA 的本质是特殊类型的哮喘,咳嗽是其唯一或主要临床 表现,无明显喘息、气促等症状或体征,有气道高反应性[1]。CVA具有与典型哮喘类似的病理生理特性:气道高反应性,气道嗜酸性粒细胞炎症和气道炎症[3-4]。30%未治疗的CVA可在数年内进展为典型哮喘[5]。  相似文献

支气管哮喘是由多种细胞和细胞组分共同参与的气道慢性变态反应性炎症。哮喘以气道慢性炎症、气道高反应性和可逆性气道阻塞为主要特征。主要炎症细胞为嗜酸性粒细胞,通常它对吸入激素治疗有反应。对中重度哮喘患者而言,吸入型皮质激素已经被推荐作为一线用药并于临床广泛应用。尽管吸入激素对缓解哮喘患者临床症状确有疗效,但我们也逐渐认识到吸入激素治疗产生的剂量相关的全身不良反应[1,2]。GINA方案也指出,应当尽可能减低吸入激素的剂量来维持对哮喘的长期控制,并推荐加用长效β2受体激动剂来改善单纯吸入皮质激素症状控制困难的中重…  相似文献

支气管哮喘主要是由肥大细胞、T淋巴细胞及嗜酸性粒细胞等多种细胞参与,以气道炎症为特征的慢性气道疾病,表现主要为胸闷、喘息、咳嗽及气急等。而慢性持续期具有病情迁延不愈、容易发作等特点[1-2]。目前,针对哮喘慢性持续期患者的治疗,西医治疗多以阻止疾病进展、缓解症状为主,但疗效并不十分满意[3]。哮喘慢性持续期属中医“哮病”范畴,中医药可延缓气道重建、控制气道炎症及调节免疫与神经内分泌等,以此可控制哮喘,且安全性良好[4-6]。本研究探讨温肺健脾汤治疗支气管哮喘慢性持续期患者临床疗效及对细胞因子的影响,现报道如下。  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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  相似文献

Objective: To observe the therapeutic effects in acupunture treatment of primary dysmenorrhea combined with spinal Tui Na, and study its mechanism. Methods: Thirty cases of the treatment group were treated by acupuncture combined with spinal Tui Na, and thirty cases in the control group were treated by routine acupuncture. Results: The total effective rate was 93.3% in the treatment group, and 73.3% in the control group, with a significant difference between the two groups (P<0.05). Conclusions: Acupuncture combined with spinal Tui Na has good prospects for treatment of primary dysmenorrhea.  相似文献

In treating chronic nephropathy,Luo Lingjie,a chief physician,pays attention to regulating the balance between yin and yang,treating infection if present,and removing pathogenic factors.He prescribes gentle drugs and uses carefully strongly warming-tonifying ones,emphasizes the importance of persuading the patient to persist in treatment with medication and nurse one's health for recuperation,and is good at combined use of TCM and western medicine therapy and brings the merits of various therapies into full play,with obvious theraoeutic effects.  相似文献
