基于L-Arg-NOS-NO通路的八段錦運動干預原發(fā)性高血壓效果的機制研究

基于L-Arg-NOS-NO通路的八段錦運動干預原發(fā)性高血壓效果的機制研究摘要：本研究旨在探究基于L-Arg/NOS/NO通路的八段錦運動干預原發(fā)性高血壓的效果機制。通過招募60名原發(fā)性高血壓患者，隨機分為運動干預組和對照組，運動干預組進行為期12周的八段錦運動，對照組維持日常生活方式不變。首先測量兩組患者的血壓水平，結果發(fā)現(xiàn)運動干預組的收縮壓和舒張壓均有不同程度的下降。接著，對運動干預組和對照組的血液和尿液樣本進行檢測，分別分析L-Arg/NOS/NO通路的關鍵指標——L-Arg含量、NOS活性以及NO水平的變化情況。結果表明，運動干預組的L-Arg含量、NOS活性和NO水平均有顯著提高，而對照組無明顯變化。進一步的細胞實驗顯示，NO的合成可以通過激活L-Arg/NOS/NO通路來實現(xiàn)。因此，本研究確認了基于L-Arg/NOS/NO通路的八段錦運動可以有效干預原發(fā)性高血壓，其機制可能與L-Arg/NOS/NO通路的調節(jié)有關。

Objectives:ThisstudyaimedtoinvestigatethemechanismoftheeffectoftheEight-SectionBrocadeexercisebasedonL-Arg/NOS/NOpathwayinterventioninprimaryhypertension.

Methods:Sixtypatientswithprimaryhypertensionwererecruitedandrandomlydividedintotheexerciseinterventiongroupandthecontrolgroup.TheexerciseinterventiongroupperformedtheEight-SectionBrocadeexercisefor12weeks,whilethecontrolgroupmaintainedtheirdailyroutine.Firstly,bloodpressurelevelsofbothgroupsweremeasured.Secondly,bloodandurinesamplesofthetwogroupswerecollected,andthekeyindicatorsoftheL-Arg/NOS/NOpathway,suchasL-Arginine(L-Arg)content,NOSactivity,andNOlevelwereanalyzed.Furthermore,cellularexperimentswereconductedtoinvestigatetheunderlyingmechanismoftheeffectoftheexerciseinterventionontheL-Arg/NOS/NOpathway.

Results:Theexerciseinterventiongroupshowedasignificantdecreaseinsystolicanddiastolicbloodpressurecomparedwiththecontrolgroup.TheL-Argcontent,NOSactivity,andNOlevelintheexerciseinterventiongroupweresignificantlyincreasedcomparedwiththoseinthecontrolgroup.InvitrocellularexperimentsconfirmedthatNOsynthesiscouldbeachievedbyactivatingtheL-Arg/NOS/NOpathway.
