Chronic obstructive pulmonary disease(COPD)is a common clinical respiratory disease,which is characterized by persistent airflow limitation,with high morbidity and death worldwide,bringing great economic and psychological pressure to patients.If COPD patients have respiratory tract infection,it is easy to progress to acute exacerbation of chronic obstructive pulmonary disease(AECOPD),which requires timely and effective treatment.At this time,the indicators related to the prognosis of COPD can greatly improve the sensitivity of clinicians,and lay a foundation for early identification of risk factors and assessment of individual death risk,timely intervention and assistance in clinical treatment.Therefore,the research on prognostic markers of COPD has become a hot spot,and some indicators of renal function and blood lipid are related to the prognosis of COPD.In view of this,this article reviews the new progress of renal function and blood lipids related to COPD,aiming to provide help for the diagnosis,treatment and prognosis of the disease.
目的 以间斑寇蛛毒素致急性肾损伤的实验大鼠为模型,从病理角度研究不同剂量的蛛毒致大鼠肾损伤的程度.方法 采集蛛毒粗毒后注射到大鼠体内,每小时观察中毒反应,24 h后观察肾功能变化,处死后进行肾脏组织病理学实验.结果 蛛毒剂量达到10 ug/kg时,实验大鼠即产生了明显的神经毒反应,随着蛛毒剂量的增加实验大鼠肾脏逐渐表现出肾小囊及肾小管间质出血、水肿、肾小球坏死、肾小管内皮细胞呈空泡样变性、肾皮质部呈玻璃样改变、肾髓质部无完整的肾小球结构及玻璃样改变的连续病变特征;然而肾功能各项指标如尿素氮、尿酸、肌酐及电解质钾、钠、钙、氯也无变化(P>0.05),但各剂量蛛毒组的尿蛋白均显著升高(3+)(P<0.01).结论 新疆间斑寇蛛的蜘蛛坏死毒素,较小剂量就可使大鼠表现出尿蛋白的大量升高,这与肾组织的病理性坏死直接相关,虽未表现出肾衰的特征,可能是与急性期的相关指标未来得及变化有关.

间斑寇蛛(Latrodectus tredecimguttatus spiders)以“黑寡妇”闻名于世,是世界剧毒蜘蛛之一[1],该蜘蛛能释放剧毒毒素,蜘蛛的螫肢(上腭)刺破人的皮肤后,毒液可经螯肢侵入人体引起中毒。被其蛰伤后会引起全身剧痛,并且会发生肝、脑、肾、心、肺等单个或多个脏器功能性或器质性病变,甚至死亡[1-5]。近些年来,在新疆各地区频繁出现间斑寇蛛蛰伤人畜事件,因此间斑寇蛛成为研究的热点。研究者从间斑寇蛛的分布及特征开始,对间斑寇蛛毒素的采集方法、成分、活性和功能以及蛰伤患者的临床表现和防治逐渐展开了深入的研究,本文主要对这些方面进行了综述,为以后更好的研究间斑寇蛛毒素和间斑寇蛛的防治奠定基础。
