1Fine particle-bound PAHs derivatives at mountain background site(Mount Tai)of the North China:Concentration,source diagnosis and health risk assessment显示文摘Ten nitrated polycyclic aromatic hydrocarbons(nPAHs)and 4 oxygenated polycyclic aromatic hydrocarbons(oPAHs)in fine particulate matter(PM2.5)samples from Mount Tai were analyzed during summer(June to August),2015.During the observation campaign,themean concentration of total nPAHs and oPAHs was 31.62 pg/m^(3)and 0.15 ng/m^(3),respectively.Two of the monitored compounds,namely 9-nitro-anthracene(9N-ANT)(6.86 pg/m^(3))and 9-fluorenone(9FO)(0.05 ng/m^(3))were the predominant compounds of nPAHs and oPAHs,respectively.The potential source and long-range transportation of nPAHs and oPAHs were investigated by the positive matrix factorization(PMF)method and the potential source contribution function(PSCF)methods.The results revealed that biomass/coal burning,gasoline vehicle emission,diesel vehicle emission and secondary formation were the dominant sources of nPAHs and oPAHs,which were mainly from Henan province and Beijing-Tianjin-Hebei region and Bohai sea.The incremental life cancer risk(ILCR)values were calculated to evaluate the exposure risk of nPAHs and oPAHs for three group people(infant,children and adult),and the values of ILCR were 7.02×10^(−10),3.49×10^(−9)and 1.41×10^(−8)for infant,children and adults,respectively.All these values were lower than the standard of EPA(Environmental Protection Agency)(<10−6),indicating acceptable health risk of nPAHs and oPAHs.Lei Zhao Shanjun Song Penghui Li Jing Liu Jing Zhang Lei Wang Yaqin Ji Jinpeng Liu Liqiong Guo Jinbao Han 2021Journal of Environmental Sciences2021,33,11:2

3Immunohistochem ical Study of T Lym phocyte Subsets onFrozen Substituted Plastic Em bedding Section of the BoneMarrow from Patients with Myelodysplastic Syndrom e andIts ClinicalIm plication显示文摘An immunohistochemical study of T lymphocyte subsets on frozen substituted plastic embedding bone marrow sections obtained from 10 patients with myelodysplastic syndrome (MDS) was presented. The results of qualitative and quantitative immunohistochemical analysis are as follows: (1) Labile antigens of T lymphocytes were well preserved, thus allowing analysis of distribution of T lymphocyte subsets in situ ; (2) the average number of T 3, T 4 and T 8 lymphocyte of the diffuse infiltrate was about 2 %, 0.4 %, 0.5 %, respectively, of all nucleated cells in bone marrow, and T 4/T 8 of T cells were below 1.0 in patients with MDS; (3) there were cases of RAS showing T lymphocyte aggregation in bone marrow, but no patient exhibited progressive refractory anemia with excess of blasts(RAEB) and RAEB in transformation (RAEBT). These findings indicated that the immunological abnormalities are of importance in the evaluation of pathogenesis and prognosis of MDS.LIU Shangqing , LIU Xiufang , ZOU Ping , SONG Shanjun , WANG Bianming Institute of Hematology, Xiehe Hospital, Tongji Medical University, Wuhan 430022 1999Journal of Huazhong University of Science and Technology(Medical Sciences)1999,19,3:0
4Sperm cryopreservation in the human sperm bank:11-year results of the Chinese mainland sperm banking network显示文摘To the Editor:Montegazza in 1866 was the first to suggest banks for frozen human semen.[1]In 1981,China's first human sperm bank was successfully established at the CITIC Xiangya Hospital.During the previous four decades,from 1981 to 2020,there were 27 human sperm banks in Chinese mainland.Human sperm banks provide cryopreservation of spermatozoa services for males needing to preserve fertility for an extended period in the Chinese mainland.Xiao Liu Qiling Wang Wenbing Zhu Zhou Zhang Wenhao Tang Huiqiang Sheng Jigao Yang Yushan Li Xiaowei Liang Tianqing Meng Zhiqiang Wang Faxi Lin Hao Dong Xiaojin He Xianglong Jiang Shanjun Dai Aiping Zhang Chunying Song Zuowen Liang Feng Zhang Xiaojun Wang Peiyu Liang Guihua Gong Xiaohong Huai Fuping Xinzong Zhang 2022Chinese Medical Journal2022,135,22:0
5组织因子/因子VII激活PI3K/Akt信号途径调控阿霉素诱导人胶质母细胞瘤细胞凋亡的研究(英文)显示文摘Objective: To investigate the role of tissue factor (TF) in chemotherapeutic reagent - induced apoptosis on human glioblastoma and explore its mechanism. Methods: The expression of TF was examined by Western blotting. The cytotoxicity of doxorubicin was determined by WST assay. The activation of Caspase-3 and PARP induced by adoxorubicin were tested by Western blotting. Results: Human glioblastoma cell line U373MG expressed high level of TF while LN-229 was with low-TF level. The chemotherapeutic reagent doxorubicin revealed stronger cytotoxic effect on high-TF U373MG cells than low-TF LN-229 cells. Enforced strong expression of TF was achieved by transfection of TF-pcDNA3 combinant on LN-229 cells in a dose-dependent manner. Enforced TF expression in transfected LN-229 cells not only impaired the doxorubicin-induced cleavage of Caspase-3 and PARP, but also inhibited the cytotoxic effect of doxorubicin. Furthermore, activation of Akt was strong in high-TF U373MG cells but weak in low-TF LN-229 cells. Incubation of factor VII (FVII) with enforced TF-expressing LN-229 cells increased the phosphorylation of Akt in a time-dependent manner. Conclusion: These results suggest that over-expression of TF on glioblastoma could inhibit doxorubicin-induced apoptosis. Interaction of FVII and TF activates the downstream PI3K/Akt pathway. Tumor-derived over-expression of TF might play a role in chemotherapy resistance in glioblastoma, at lest in part, by activating PI3K/Akt-mediated survival and anti-apoptotic mechanism through the interaction of TF/FVII signaling.Hao Tang Jun Fang Kai Shu Muxiang Zhou Shanjun Song Ling Li Ting Lei 2007The Chinese-German Journal of Clinical Oncology2007,6,5:0
