Evaluation of correlation between PM2.5 and radon-progeny equilibrium factor in radon chamber

引用

Nuclear Science and Techniques 2018年第10期29卷 261-267页

作者： Li-Fan Li rui chen Shu-Min Zhou Bin Tang Engineering Research Center of Nuclear Technology Application Ministry of Education East China University of Technology

The dosage of environmental radon progeny is typically estimated according to the environmental radon exposure and the recommended radon-progeny equilibrium factor, F. To investigate the relationship between PM2.5 and the radon-progeny equilibrium factor, cigarettes are used to simulate the haze–fog in a multi-functional radon chamber to achieve a stable radon concentration environment. A radon detector and a portable laser aerosol spectrometer are used to obtain the values for C_(mean) PM2.5,C_(Rn), and C_p. The results show that the mean values of F conform with the typical value recommended by the United Nations Scientific Committee on the Effects of Atomic Radiation and are within the reasonable range of0.1–0.9. In this study, a positive correlation is observed between the F values and PM2.5 concentrations.

Shenfu injection(SFI), a Chinese medicinal product, shows potent efficacy in treating sepsis. The aim of the present study was to clarify the protective effects of SFI against lipopolysaccharide(LPS)-induced myocardial inflammation and *** were carried out in Sprague-Dawley(SD) rats treated with LPS or LPS + SFI, and in H9 C2 cardiomyocytes. The sepsisassociated myocardial inflammation and apoptosis was induced by the intraperitoneal injection of LPS(20 mg·kg–1). SFI attenuated the increased expression of tumor necrosis factor(TNF)-α and interleukin(IL)-1β induced by LPS both in serum and heart. In LPS group,cell viability was reduced, and reversed after SFI administration. LPS treatment increased the expression levels of cleaved-caspase 3 and Bax, and those of Bcl2 and Bcl2/Bax. These two trends were reversed by SFI administration. The expression levels of phosphorylated mitogen-activated protein kinase kinase(p-MEK) and phosphorylated extracellular regulated protein kinases(p-ERK) were increased by LPS, and reversed by SFI. MEK inhibitor U0126 attenuated the apoptosis induced by LPS. These results indicate that SFI could treat LPS-induced cardiac dysfunction. In conclusion, SFI attenuates the inflammation and apoptosis induced by LPS via downregulating the MEK and ERK signaling pathways.

Role of Immune Microenvironmental Factors for Improving the IPI-related Risk Stratification of Aggressive B Cell Lymphoma

引用

Biomedical and Environmental Sciences 2017年第7期30卷 492-500页

Objective To investigate the risk stratification of aggressive B cell lymphoma using the immune microenvironment and clinical factors. Methods A total of 127 patients with aggressive B cell lymphoma between 2014 and 2015 were enrolled in this study. CD4, Foxp3, CDS, CD68, CD163, PD-1, and PD-L1 expression levels were evaluated in paraffin-embedded lymphoma tissues to identify their roles in the risk stratification. Eleven factors were identified for further evaluation using analysis of variance, chi-square, and multinomial logistic regression analysis. Results Significant differences in 11 factors （age, Ann Arbor stage, B symptom, ECOG performance status, infiltrating CD8＋ T cells, PD-L1 expression, absolute blood monocyte count, serum lactate dehydrogenase, serum iron, serum albumin, and serum l^2-microglobulin） were observed among patient groups stratified by at least two risk stratification methods [International Prognostic Index （IPI）, revised IPI, and NCCN-IPI models] （P 〈 0.05）. Concordance rates were high （81.4%-100.0%） when these factors were used for the risk stratification. No difference in the risk stratification results was observed with or without the Ann Arbor stage data. Conclusion We developed a convenient and inexpensive tool for use in risk stratification of aggressive B cell lymphomas, although further studies on the role of immune microenvironmental factors are needed.

Prostate cancer research in China

引用

Asian Journal of Andrology 2013年第3期15卷 350-353页

作者： Shan-cheng Ren rui chen Ying-Hao Sun Department of Urology Shanghai Changhai Hospital Second Military Medical University Shanghai 200433 China

Prostate cancer （PCa） research in China has been on a rocketing trend in recent years. The first genome-wide association study （GWAS） in China identified two new PCa risk associated single nucleotide polymorphisms （SNPs）. Next generation sequencing is beginning to be used, yielding novel findings： gene fusions, long non-coding RNAs and other variations. Mechanisms of PCa progression have been illustrated while various diagnosis biomarkers have been investigated extensively. Personalized therapy based on genetic factors, nano-medicine and traditional Chinese medicine has been the focus of experimental therapeutic research for PCa. This review intends to shed light upon the recent progress in PCa research in China and points out the possible breakthroughs in the future.
