农民是新农村建设的主体,农民有序政治参与是构建社会主义新农村的基石,农民政治参与的积极性和参与程度直接关系到社会主义新农村建设的历史进程。农民政治参与对农村民主政治的发展有着积极的影响,而农民的政治参与不成熟,则会对我国的民主发展产生消极影响。政府与村民博弈的非均衡性,农民政治参与动机的自利性,村民的政治参与的非制度化,是导致农民政治参与缺失的主要根源。大力发展农村经济,规范地方政府行为并深化基层的政权改革,加强农民的政治素养教育,是提高农民政治参与程度和水平的现实选择。

AIM:To evaluate the predictive value of superficial retinal capillary plexus(SRCP)and radial peripapillary capillary(RPC)for visual field recovery after optic cross decompression and compare them with peripapillary nerve fiber layer(pRNFL)and ganglion cell complex(GCC).METHODS:This prospective longitudinal observational study included patients with chiasmal compression due to sellar region mass scheduled for decompressive *** estimating equations were used to compare retinal vessel density and retinal layer thickness preand post-operatively and with healthy *** regression models were used to assess the relationship between preoperative GCC,pRNFL,SRCP,and RPC parameters and visual field recovery after ***:The study included 43 eyes of 24 patients and 48 eyes of 24 healthy *** RPC and SRCP vessel density and pRNFL and GCC thickness were lower than healthy controls and higher than postoperative *** best predictive GCC and pRNFL models were based on the superior GCC[area under the curve(AUC)=0.866]and the tempo-inferior pRNFL(AUC=0.824),and the best predictive SRCP and RPC models were based on the nasal SRCP(AUC=0.718)and tempo-inferior RPC(AUC=0.825).There was no statistical difference in the predictive value of the superior GCC,tempo-inferior pRNFL,and tempo-inferior RPC(all P>0.05).CONCLUSION:Compression of the optic chiasm by tumors in the saddle area can reduce retinal thickness and blood *** reduction persists despite the recovery of the visual field after decompression ***,pRNFL,and RPC can be used as sensitive predictors of visual field recovery after decompression surgery.
