摘要
研究青礞石对慢性阻塞性肺疾病急性加重期(acute exacerbation of chronic obstructive pulmonary disease,AECOPD)痰热证模型大鼠血浆及肺组织中金属元素的影响。采用烟熏结合肺炎克雷伯菌感染的方法复制AECOPD痰热证大鼠模型,给予青礞石干预后,利用ICP-OES、ICP-MS测定各组大鼠血浆及肺组织中金属元素含量,利用SPSS 18.0统计软件进行各金属元素的变化等相关分析。结果青礞石可显著上调模型组大鼠血浆中铁(Fe)、铝(Al)、锰(Mn)、铜(Cu)、锌(Zn)、锡(Sn)(P<0.05),钒(V)、钴(Co)(P<0.01)及Cu/Zn(P<0.05)的含量,显著下调钛(Ti)(P<0.05)和铅(Pb)的含量(P<0.05);显著上调模型组大鼠肺组织中铍(Be)含量(P<0.05),下调镁(Mg)、Ti、Al含量(P<0.01)。正常组、模型组和青礞石组血浆、肺组织样品元素轮廓能很好地分离;血浆、肺组织样品青礞石组与其他组可分为两大类。差异代谢物中以血浆中牛磺酸(taurine)及肺组织植物鞘氨醇(phytosphingosine)与差异金属元素关系最为密切。青礞石中Fe、Al、Mg、Be、Ti、V、Mn、Cu、Zn、Sn、Co等元素可能直接或间接参与了AECOPD大鼠的干预作用,该金属元素群可能是青礞石作用于AECOPD大鼠的物质基础,同时降低了体内的Cu/Zn。进一步证实了青礞石通过干预AECOPD大鼠血浆和尿液牛磺酸和亚牛磺酸代谢(taurine and hypotaurine metabolism)通路、肺组织鞘脂类代谢(sphingolipid metabolism)通路的效应机制。此外,该研究证实了长期吸烟可引起镉(Cd)在肺部的高度富集并损伤肺组织。
The effects of Chloriti Lapis on metal elements in plasma and lung tissue of acute exacerbation of chronic obstructive pulmonary disease( AECOPD) rats were studied. The rat AECOPD model with phlegm heat syndrome was established by smoking combined with Klebsiella pneumoniae infection. After the rats were treated by Chloriti Lapis,the contents of metal elements in plasma and lung tissue were determined by inductively coupled plasma-optical emission spectroscopy( ICP-OES) and inductively coupled plasma mass spectrometry( ICP-MS). The changes in the contents of metal elements were analyzed by SPSS 18. 0. Further,the correlations of differential metal elements( including Cu/Zn ratio) with differential metabolites in plasma,lung tissue and urine of AECOPD rats treated with Chloriti Lapis were analyzed. The results showed that Chloriti Lapis significantly up-regulated the contents of Fe,Al,Mn,Cu,Zn,Sn( P<0. 05),V,Co( P< 0. 01) and Cu/Zn ratio( P< 0. 05),and significantly down-regulated the contents of Ti( P< 0. 05)and Pb( P<0. 05) in the model rat plasma. It significantly increased the content of Be( P<0. 05) and decreased the contents of Mg,Ti and Al( P<0. 01) in model rat lung tissue. The element profiles of normal group,model group and Chloriti Lapis group can be well separated. Chloriti Lapis group and other groups were clustered into two categories. The taurine in plasma and phytosphingosine in lung tissue had the strongest correlations with differential metal elements. The Fe,Al,Mg,Be,Ti,V,Mn,Cu,Zn,Sn,and Co in Chloriti Lapis may directly or indirectly participate in the intervention of AECOPD rats. This group of metal elements may be the material basis of Chloriti Lapis acting on AECOPD rats,and reduce the Cu/Zn value in vivo. It was further confirmed that Chloriti Lapis could interfere with the metabolic pathways of taurine and hypotaurine in plasma and urine as well as the sphingolipid metabolism pathway in lung tissue of AECOPD rats. In addition,this study confirmed that long-term smoking can cause high-conce
