[Objective] The deliver amount and deliver rate of heavy metal elements during smoking were studied, which could provide a reference for reducing the damage of cigarette products. [Method] Two pretreatment methodsof microwave di- gestion and acid extraction were used to process the ash content, the total particu- late matter of mainstream smoke （TPM） and cigarette filter. Detection results of heavy metal elements were compared by the two methods. [Result] The microwave digestion method was better than acid solution extraction method on analysis of TPM, but presented disadvantages on analysis of ash and filter. Meanwhile, the migration amount and rate were studied and resultsshowed that most heavy metal elements were escaped along with sidestream smoke between 66.89% and 95.48%, and almost all Hg escaped through sidestream smoke. Other heavy metal elements, except Hg, were separately found in ash, TPM and filter. Cr, Ni, As and Se were mostly residual in ash, followed by TPM, and filter had the least, while Cd and Pb were just in the reverse order. Normally, 5% or less heavy metal elements were transferred to TPM, only a small part of which could reach 5%-10%. [Conclusion] Most of the heavy metal elements are taken by sidestream smoke, ash and filter, while the migration amounts to mainstream smoke are extremely low.

类风湿性关节炎(RA)是一种器官特异性自身免疫疾病,特征在于慢性滑膜炎和骨质侵蚀,其高致残率会对社会和个人造成严重影响,因此需要有效可靠的RA诊断标志物和治疗靶点。本研究从GEO数据库下载了表达谱数据集和单细胞测序数据集,以阐明RA中潜在的候选基因和途径。首先,利用单细胞测序数据注释了5类细胞簇,筛选出每个细胞簇与RA相关的基因4109个,进行了基因本体(GO)和京都基因和基因组百科全书(KEGG)途径富集分析。其次,利用生物信息学方法分析表达数据,共鉴定出677个与RA相关的基因,进行了差异表达基因的GSEA富集分析。最后,对差异表达基因(DEG)和每个簇的差异表达基因进行关联分析,再利用LASSO算法进一步分析,获得了6个关键基因,分别是IGLL5、AIM1、NKG7、PSMB9、ANKRD11和BIRC3,这6个基因在训练集与验证集的ROC曲线显示其在类风湿关节炎中具有良好的诊断性能。

A novel method for the preparation of β- cyclodextrin grafted graphene oxide （GO-β-CD） has been developed. The GO-β-CD was characterized by Fourier transform infrared spectroscopy, 13C NMR spectroscopy, Raman spectroscopy and thermogravimetric analysis. The ability of GO-β-CD to remove fuchsin acid from solution was also studied. The GO-β-CD had an excellent adsorption capacity for fuchsin acid and could be recycled and reused. The adsorption capacities of GO-β-CD for other dye pollutants such as methyl orange and methylene blue were also investigated. The absorption capacities for the three dyes are in the order： fuchsin acid 〉 methylene blue 〉 methyl orange.
