南京林业大学学报（自然科学版） 2012年第3期36卷 91-95页

作者：黄润州 WU Qinglin 张洋南京林业大学木材工业学院江苏南京210037 School of Renewable Natural Resources Louisiana State University Baton Rouge 70803 USA

以高密度聚乙烯(HDPE 6761)为基体,松木纤维(Pine)为增强材料,MAPE(EpoleneG2608)、MAPP(Exxelor VA1840)和Fusabond(WPC576D)为偶联剂,采用注塑法制备木塑复合材料(WPC),并测定了HDPE基体和不同配比WPC的热膨胀性能与冲击强度。结果表明:WPC的冲击强度明显低于高密度聚乙烯板(HDPE),较低的冲击强度是木塑复合材料的一个主要缺点,偶联剂的加入可以提高WPC的冲击强度;WPC的热膨胀系数明显低于HDPE,虽然偶联剂的加入可以较好地抑制热膨胀,但WPC的热膨胀系数的主要影响因素是木纤维的加入量及塑料基体的种类。

Expression of TRAIL and its receptors in primary hepatic carcinoma and apoptosis-inducing effect of HrsTRAIL on hepatoma cell line HepG2

引用

Journal of Nanjing Medical University 2006年第6期20卷 372-376页

作者： Mingbing Xiao Jiefei huang runzhou Ni Jing Zhu Hong Zhang Qun Wei Feng Jiang Baijun Bao Department of Gastroenterology Affiliated Hospital of Nantong University Nantong 226001 China

Objective： To investigate the expression of tumor necrosis factor-related apoptosis-inducing ligand（TRAIL） and its receptors in primary hepatic carcinoma （PHC） and the apoptosis-inducing effect on hepatoma cell line HepG2. Methods： TRAIL and its receptors were detected by semiquantitive RT-PCR in 30 PHC and para-carcinoma tissues and two hepatoma cell lines of HepG2 and SMMC-7721. HepG2 cells were treated with human recombinant soluble TRAIL protein （HrsTRAIL） and then the viability of HepG2 cells was measured by microculture tetrazolium dye（MTT） assay and apoptosis index was demonstrated by fluorescence-activated cell sorting （FACS）. Results：TRAIL and its receptors were detectable in all PHC and para-carcinoma tissues and hepatoma cell line HepG2. TRAIL, death receptor 4 （DR4）, DR5, and decoy receptor 2 （DcR2） but not DcR1 were detectable in hepatoma cell line SMMC-7721. The expression patterns of TRAIL receptors in HepG2 were quite similar to PHC specimens. The semiquantitive results showed that the expression level of TRAIL and DcR were lower but DR was higher in hepatoma tissues than in para-carcinoma tissues. In PHC tissues, the expressions of DR were higher than DcR, while there was no difference in para-carcinoma tissues. HrsTRAIL had potent antitumor activity in a time- and dose-dependent manner. After co-incubations of the HepG2 cells in the presence of HrsTRAIL at concentration 1 000 ng/ml for 24 hours, the viability of HepG2 cells decreased to 45% and the apoptosis index reached 51%. Conclusion ：TRAIL and its receptors were expressed in both PHC tissues and para-carcinoma tissues but the expression levels were different. The lower expression of TRAIL in PHC tissues suggested that insufficient apoptosis occured in the development of PHC. High expression of DR in PHC tissues may be a self-defense mech- anism and may afford a theory of HrsTRAIL therapy for PHC. HrsTRAIL may be a potential cytotoxic drug for PHC, and it can kill majority of HepG2 cells, but m
