Based on related statistical data during 1980-2014,change rule of Guangxi cultivated land pressure level was studied. Taking each municipal administrative division as evaluation unit,temporal-spatial change trend of cultivated land pressure level was explored by establishing pressure index model of cultivated land,and principal component analysis was used to explore the driving force of cultivated land pressure. Results showed that from 1980 to 2014 in Guangxi,cultivated land pressure was at level one in 12 years,level two in 19 years and level three in 4 years; mean of cultivated land pressure in each city during 2005-2014 was taken as average level of cultivated land pressure in the city,in which cultivated land pressure values of Chongzuo City,Baise City,Laibin City,Liuzhou City,Fangchenggang City,Nanning City,Hechi City and Guigang City were all lower than average level in Guangxi at the same period. Driving factors of cultivated land pressure index mainly contained urbanization rate,Engel coefficient of rural households(ECRH),per capita cultivated land area,total population and rural per capita net income(RPFI). 展开更多

Ubiquitination is a highly conserved and fundamental posttranslational modification(PTM)in all eukaryotes regulating thousands of proteins.The RING(really interesting new gene)finger(RNF)protein,containing the RING domain,exerts E3 ubiquitin ligase that mediates the covalent attachment of ubiquitin(Ub)to target proteins.Multiple reviews have summarized the critical roles of the tripartite-motif(TRIM)protein family,a subgroup of RNF proteins,in various diseases,including cancer,inflammatory,infectious,and neuropsychiatric disorders.Except for TRIMs,since numerous studies over the past decades have delineated that other RNF proteins also exert widespread involvement in several diseases,their importance should not be underestimated.This review summarizes the potential contribution of dysregulated RNF proteins,except for TRIMs,to the pathogenesis of some diseases,including cancer,autoimmune diseases,and neurodegenerative disorder.Since viral infection is broadly involved in the induction and development of those diseases,this manuscript also highlights the regulatory roles of RNF proteins,excluding TRIMs,in the antiviral immune responses.In addition,we further discuss the potential intervention strategies targeting other RNF proteins for the prevention and therapeutics of those human diseases. 展开更多
