目的 分析朱砂莲中毒导致急性肾功能衰竭临床表现、肾脏病理学及相关文献复习。 方法 2007年3月-9月收治朱砂莲中毒急性肾功能衰竭2例,分析临床表现及肾脏病理损害。 结果 朱砂莲急性中毒易致急性肾功能衰竭,危及生命;其主要损害肾小管间质,表现为急性肾小管重度损伤,无炎性细胞浸润,而肾小球几乎无病变。 结论 朱砂莲为我国常使用中药,主要成分为马兜铃酸,易致马兜铃酸肾病,须提高对该病认识,规范使用中草药,避免药物性所致肾损害。Objective To analyze the clinical and pathological manifestations of kidney in patients with ciliatenerve knotweed root-induced acute renal failure. Methods Two patients who were admitted into our hospital for acute renal failure caused by over-dose ciliatenerve knotweed root from March to September in 2007 were included in this study. We analyzed the clinical and pathological manifestations of their kidneys. Results Over-dose ciliatenerve knotweed root could induce acute renal failure, even threaten life. The pathology of kidney is characterized by severe tubular injury,rather than glomerulus damage, without cell infiltration. Conclusions Ciliatenerve knotweed root is one of the frequently-used traditional Chinese medicines in our country, which can easily result in aristolochinc acid nephropathy. We should recognize the importance of this disease and avoid using nephrotoxic drugs.
Xiyanping is used to treat infectious diseases with antibiotics in clinic. The aim of this study is to investigate the mechanism of Xiyanping through studying the effect of the combination of Xiyanping with Cefazolin on the chemotaxis and phagocytic function of peripheral blood neutrophils in mice. Ten healthy mice were in control group. Forty healthy mice in experimental group were infected with staphylococcus aureus, and were randomly divided further into four groups, i.e. model group, Xiyanping group, Cefazolin group and combination group (Xiyanping with Cefazolin). Mice in the control group and model group were given normal saline (NS) through abdomen while those in other groups were given Xiyanping, Cefazolin, and Xiyanping with Cefazolin, respectively. The chemotaxis of peripheral blood neutrophils was detected with the transwell method, and the phagocytic function of peripheral blood neutrophils was analyzed with flow cytometry (FCM). In the present study, there was no significance on the chemotactic index of peripheral blood neutrophils in all the groups (P>0.05). The actual phagocytotic rate and index of peripheral blood neutrophils in the blank group, Xiyanping group, and the combination group were significantly higher than those of the model group and Cefazolin group (P<0.05). However, those were not significant in the blank group, Xiyanping group, and the combination group (P>0.05) or between the model group and Cefazolin group (P>0.05). Our results suggested the combination of Xiyanping and Cefazolin could enhance the therapeutic effect by improving the phagocytic function of peripheral blood neutrophils.
