Sesquiterpenoids are a class of 15-carbon secondary metabolites that play diverse roles in plant adaptation to *** plants accumulate a large amount of sesquiterpene aldehydes(including gossypol)as phytoalexins against pathogens and *** are stored in pigment glands of aerial organs and in epidermal layers of *** enzymes of gossypol biosynthesis pathway have been characterized,including 3-hydroxy-3-methylglutaryl coenzyme A reductase(HMGR)and farnesyl diphosphate synthase(FPS)that catalyze the formation of the precursor farnesyl diphosphate(FPP),(+)-δ-cadinene synthase(CDN)which is the first enzyme committed to gossypol biosynthesis,and the downstream enzymes of CYP706B1 and *** of these genes are tightly regulated during cotton plants development and induced by jasmonate and fungi *** transcription factor Ga WRKY1 has been shown to be involved in gossypol pathway *** development of new genomic platforms and methods and releases of diploid and tetraploid cotton genome sequences will greatly facilitate the elucidation of gossypol biosynthetic pathway and its regulation.

目的:探讨电针治疗无器质病变的Z综合征(代谢综合征与阻塞性睡眠呼吸暂停低通气综合征共同存在的病症)的疗效及作用机制。方法:58例Z综合征患者按轻中重度分3组,采用针刺与电针治疗,穴取带脉、中脘、下脘、足三里、气海、滑肉门等,每天1次,每周5次,10次为一疗程,连续治疗2个疗程。分别于电针治疗前及治疗后1周进行睡眠呼吸监测(PSG),并检测各组治疗前后三酰甘油(TG)、空腹血糖(FBG)、空腹胰岛素(INS)、血清瘦素(Lep)的变化。结果:3组患者治疗后呼吸暂停-低通气指数(AHI)、血氧饱和度(SaO2)<90%的时间占总睡眠时间的百分比(SLT90%)均有明显改善(均P<0.05)。3组患者治疗后TG、FPG、INS、Lep水平均有下降(均P<0.05)。结论:电针治疗Z综合征可改善AHI及夜间低氧状况,其作用机制可能与降低代谢综合征指标及瘦素水平有关。
