ABSTRACT
ObjectiveTo understand the composition of related characteristics of HIV/AIDS cases in Lanzhou and analyze the influencing factors of AIDS-related deaths. MethodsThe information of HIV/AIDS cases reported in Lanzhou from 2011 to 2019 was collected， the method of survival was used analysis and Bayesian Cox Proportional Hazard Regression Model was constructed to analyze the related factors of death. ResultsA total of 2 312 HIV/AIDS patients were selected in this study， including 45 AIDS-related deaths. The results of multivariate regression showed that the older the patients were， the higher the risk of death was； the risk of death of AIDS patients at the time of diagnosis was 13.91 times higher than that of HIV-infected patients； Patients who received CD4 testing had a lower risk of death than those who did not； The risk of death was 0.22 times higher among those who received antiretroviral therapy than those who did not receive antiretroviral therapy. ConclusionsAge at diagnosis， course of disease， antiviral therapy were the influencing factors of AIDS-related death in HIV/AIDS patients in Lanzhou. Therefore， it is necessary to strengthen health education for AIDS-related groups， advocate early detection， early diagnosis， and early treatment， expand the coverage of AIDS testing and treatment， prolong the survival time of AIDS patients.
ABSTRACT
ISG15 is a 15kD ubiquitin-like protein (UBL) induced by interferon (IFN). ISG15 can be covalently attached to proteins, which is called ISGylation process. ISGylation system contains ISG15, UBE1L, UBCH8 and HERC5 proteins, which are all essential for ISGylation. ISG15 and ISGylation system have been found to have anti-viral effects. A better understanding of how ISG15 mediates the anti-viral activity will provide insights for new anti-viral drugs development and new therapeutic strategies. The mechanisms underlying the ISG15 mediated anti-viral response have been explored extensively in recent years. This minireview summarized the research advances of how ISG15 mediated the anti-viral effects against different kinds of viruses.

Tumor suppressor p53, known as 'the guardian of the genome', has the ability to prevent the emergence of transformed cells by the induction of cell cycle arrest and apoptosis. Otherwise, there were researches about the function of p53, such as NDA repair, regulating metabolism and maternal reproduction in recent years. Furthermore, there was a new function for p53 in antiviral apoptosis mentioned in the research, Integration of interferon-alpha/beta signaling to p53 responses in tumour suppression and antiviral defense. In order to define the antiviral function of p53, many target genes has been defined, such as IRF9, IRF5, ISG15 and TLR3. All of these implied there must be a complex mechanism for role of p53 in antiviral innate immunity, adaptive immunity and inflammation.
