目的观察下鼻甲去骨及黏膜划痕微创减容术治疗慢性肥厚性鼻炎对鼻黏膜传输功能的影响。方法应用糖精试验测定(实验组,30例慢性肥厚性鼻炎病人)术前、下鼻甲去骨及黏膜划痕微创减容术后3个月、术后6个月鼻腔黏膜纤毛输送率(mucociliary transport rat,MTR);同时与行下鼻甲部分切除术的慢性肥厚性鼻炎病人(对照组,30例)进行比较。结果实验组术后3、6个月鼻黏膜纤毛输送率(MTR)分别与术前比较无明显变化(P>0.05),而对照组分别较术前明显减慢(均P<0.01),与实验组相比,对照组术后3个月、6个月MTR均减慢(P<0.01)。结论下鼻甲去骨及黏膜划痕微创减容术治疗慢性肥厚性鼻炎对鼻黏膜纤毛无明显影响,对鼻腔黏膜正常生理结构影响不大。

Modern semi-dwarf rice varieties of the“Green Revolution”require a high supply of nitrogen(N)fertilizer to produce high yields.A better understanding of the interplay between N metabolism and plant developmental processes is required for improved N-use efficiency and agricultural ***,we show that strigolactones(SLs)modulate root metabolic and developmental adaptations to low N availability for ensuring efficient uptake and translocation of available *** key repressor DWARF 53(D53)of the SL signaling pathway interacts with the transcription factor GROWTH-REguLATING FACTOR 4(GRF4)and prevents GRF4 from binding to its target gene promoters.N limitation induces the accumulation of SLs,which in turn promotes SL-mediated degradation of D53,leading to the release of GRF4 and thus promoting the expression of genes associated with N metabolism.N limitation also induces degradation of the DELLA protein SLENDER RICE 1(SLR1)in an D14-and D53-dependent manner,effectively releasing GRF4 from competitive inhibition caused by ***,our findings reveal a previously unrecognized mechanism underlying SL and gibberellin crosstalk in response to N availability,advancing our understanding of plant growth–metabolic coordination and facilitating the design of the strategies for improving N-use efficiency in high-yield crops.

宋元时期是老学发展的一个高峰 ,不但解《老》著作众多 ,而且学术观点各异。本文通过对王安石、宋徽宗、江、程大昌、杜道坚老学著作的考察 ,认为以儒释《老》是该时期老学发展的主要特点之一 ,并且 ,从王安石将老子的自然之道与儒家的经世之学结合起来到杜道坚把《老子》解释为一套“皇道帝德”之术 ,可以得出一条较鲜明的思想线索 ,即老学不断与儒学和现实政治靠拢、合流 ,从而反映了宋元时期孔老同归、儒道交融这种思想发展的历史总趋势。
