[Objective] The aim was to introduce the development and application of 2BDQ-8 rice direct sowing machine and provide a theoretical basis for rice mechanization production. [Method] 2BDQ-8 rice direct sowing machine was used for the promotion test in field of several cities and counties in Jiangsu Province,and artificial rice planting and mechanization rice planting were compared to explore the production and economic situation. [Result] 2BDQ-8 rice direct sowing machine had advantages such as high efficiency and low cost,the rice direct sowing machine saved about 30% compared to the artificial rice planting and mechanization rice planting,and the overall efficiency was significant. [Conclusion] 2BDQ-8 rice sowing machine was a production technology that had low cost and high efficiency,which should be widely applied. 展开更多

目的:探索不同浓度葡萄糖(Glu)及脂多糖(LPS)对SD大鼠胰腺β细胞胰岛素分泌的影响。方法:体外原代培养8周龄大鼠胰腺组织,根据析因分析设计为4组:C+LPS 40(Glu 5 mmol/L+LPS 40pg/mL),C+LPS 200(Glu 5 mmol/L+LPS 200 pg/mL),HG+LPS 40(... 目的:探索不同浓度葡萄糖(Glu)及脂多糖(LPS)对SD大鼠胰腺β细胞胰岛素分泌的影响。方法:体外原代培养8周龄大鼠胰腺组织,根据析因分析设计为4组:C+LPS 40(Glu 5 mmol/L+LPS 40pg/mL),C+LPS 200(Glu 5 mmol/L+LPS 200 pg/mL),HG+LPS 40(Glu 25 mmol/L+LPS 40 pg/mL),HG+LPS 200(Glu 25 mmol/L+LPS 200 pg/mL)。培养48 h后,利用实时荧光定量-聚合酶链反应(Q-PCR)检测这4组培养基内胰岛素m RNA表达,免疫荧光观察比较高糖和高LPS对大鼠胰腺内胰岛素合成情况的差异。结果:高糖和高LPS均能显著降低大鼠胰腺胰岛素的表达量(P<0.05)。高糖能使胰腺中胰岛素mRNA的表达下降39.58%(P<0.05),高LPS能使胰腺中胰岛素m RNA的表达下降40.50%(P<0.05),2种因素之间存在交互作用(P<0.05)。结论:高糖和高LPS均能对胰腺β细胞造成损伤,显著减少胰岛素的合成与释放。LPS对胰岛β细胞的损伤作用在T2DM的发生发展过程中起着重要作用。 展开更多
