余光中和散文家思果谈及一次临上机前,他们的另一个朋友高克毅行西礼向两女士虚拥亲颊。思果再三叹道:“怎么可以这样?当众拥吻人家的太太?”余光中立即回答说:“怎么样,当众不得,难道要私下做吗?”  相似文献

基于可持续发展的新型农村合作医疗制度改革初探   总被引:1,自引:0,他引:1  
建立新型农村合作医疗制度是政府关注民生,解决农民因病致贫、因病返贫问题的重要举措。我国于2003年开始新型农村合作医疗的试点,目前已取得重大进展。到2006年末,新型农村合作医疗试点范围扩大到1451个县(市、区),占全国总数的50.7%,有4.1亿农民参加。2007年,按国务院部署,试点范围将扩大到全国80%以上的县(市、区)。  相似文献

Objective To study the effect of procalcitonin (PCT) on lipopolysaccharide (LPS)-induced expression of the pyroptosis-related proteins nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) and caspase-1 in human umbilical vein endothelial cells (HUVECs). Methods HUVECs were induced by LPS to establish a model of sepsis-induced inflammatory endothelial cell injury. The experiment was divided into two parts. In the first part, HUVECs were randomly divided into four groups: normal control, LPS (1 μg/mL), PCT (10 ng/mL), and LPS+PCT (n=3 each). In the second part, HUVECs were randomly grouped: normal control, LPS, and LPS+PCT of different concentrations (0.1, 1, 10, and 100 ng/mL) (n=3 each). Quantitative real-time PCR and Western blot were used to measure the mRNA and protein expression levels of NLRP3 and caspase-1 in each group. Results In the first experiment: compared with the normal control group, the PCT, LPS, and LPS+PCT groups had significantly upregulated mRNA and protein expression levels of NLRP3 and caspase-1 (P<0.05); compared with the LPS group, the LPS+PCT group had significantly downregulated mRNA and protein expression levels of NLRP3 and caspase-1 (P<0.05). In the second experiment: compared with those in the LPS group, the mRNA and protein expression levels of NLRP3 and caspase-1 in the LPS+PCT of different concentrations groups were significantly downregulated in a concentration-dependent manner (P<0.05). Conclusions LPS can promote the expression of the pyroptosis-related proteins NLRP3 and caspase-1 in HUVECs, while PCT can inhibit the LPS-induced expression of the pyroptosis-related proteins NLRP3 and caspase-1 in HUVECs in a concentration-dependent manner. © 2023 Xiangya Hospital of CSU.
