高鎂飲食通過調(diào)控鎂轉(zhuǎn)運(yùn)體降低肺高壓摘要:肺高壓是一種較為復(fù)雜的病理學(xué)情況,早期病因不明,難以對肺高壓進(jìn)行治療。本文依據(jù)鎂離子對肺血管生成重要影響,旨在探究高鎂飲食的鎂轉(zhuǎn)運(yùn)體調(diào)節(jié)機(jī)制是否會影響肺高壓的發(fā)病和治療。在本次研究中,將采用大腸桿菌表達(dá)人類鎂轉(zhuǎn)運(yùn)體和肺動脈平滑肌細(xì)胞篩選成功篩選能夠顯著提高鎂離子內(nèi)流的高通量分子。在高鎂飲食、低鎂飲食及空白對照三組實驗中,發(fā)現(xiàn)高鎂飲食可通過調(diào)節(jié)鎂離子的內(nèi)流量,直接降低肺血管的緊張情況。同時,肺血管內(nèi)皮細(xì)胞和平滑肌細(xì)胞中的細(xì)胞膜離子渠道亦被明顯引導(dǎo)。因此,高鎂飲食可通過調(diào)節(jié)鎂轉(zhuǎn)運(yùn)體而緩解肺高壓的發(fā)病。

Abstract:Pulmonaryhypertensionisacomplexpathologicalcondition,andtheearlyetiologyisunclear,makingitdifficulttotreatpulmonaryhypertension.Basedonthesignificanteffectsofmagnesiumionsonpulmonaryvasculardevelopment,thispaperaimstoexplorewhetherthemagnesiumtransportmechanismofhighmagnesiumdietcanaffecttheoccurrenceandtreatmentofpulmonaryhypertension.Inthisstudy,ahigh-throughputmoleculethatcansignificantlyincreasetheintracellularflowofmagnesiumionswassuccessfullyscreenedbyexpressinghumanmagnesiumtransportersbyE.coliandscreeningofpulmonaryarterysmoothmusclecells.Inthethreegroupsofexperimentsofhighmagnesiumdiet,lowmagnesiumdiet,andblankcontrol,itwasfoundthathighmagnesiumdietcandirectlyreducethetensionofpulmonarybloodvesselsbyadjustingtheintracellularflowofmagnesiumions.Atthesametime,ionchannelsonthecellmembraneofpulmonaryvascularendothelialcellsandsmoothmusclecellswerealsosignificantlyregulated.Therefore,highmagnesiumdietcanalleviatetheoccurrenceofpulmonaryhypertensionbyregulatingmagnesiumtransporters.
