四君子湯對脾虛大鼠腸道菌群多樣性的影響一、本文概述Overviewofthisarticle本文旨在探討四君子湯對脾虛大鼠腸道菌群多樣性的影響。脾虛是中醫(yī)學中的一種病理狀態(tài)，主要表現(xiàn)為消化功能減弱、食欲不振、體重下降等癥狀。近年來，隨著微生物組學的發(fā)展，腸道菌群與宿主健康的關(guān)系受到了廣泛關(guān)注。本研究以脾虛大鼠為模型，通過給予四君子湯干預，觀察其對腸道菌群結(jié)構(gòu)、多樣性及功能的影響，以期為脾虛的中醫(yī)藥治療提供理論依據(jù)。ThisarticleaimstoexploretheeffectofSijunziTangonthediversityofgutmicrobiotainratswithspleendeficiency.SpleendeficiencyisapathologicalconditionintraditionalChinesemedicine,mainlymanifestedasweakeneddigestivefunction,lossofappetite,weightloss,andothersymptoms.Inrecentyears,withthedevelopmentofmicrobiome,therelationshipbetweengutmicrobiotaandhosthealthhasreceivedwidespreadattention.ThisstudyusedspleendeficiencyratsasamodelandintervenedwithSijunziTangtoobserveitseffectsonthestructure,diversity,andfunctionofintestinalmicrobiota,inordertoprovidetheoreticalbasisforthetreatmentofspleendeficiencywithtraditionalChinesemedicine.四君子湯作為中醫(yī)經(jīng)典方劑之一，具有益氣健脾、和中養(yǎng)胃的功效，廣泛用于治療脾胃虛弱引起的各種疾病。本研究采用現(xiàn)代生物學技術(shù)，如高通量測序、生物信息學分析等，對脾虛大鼠的腸道菌群進行深入研究，以期揭示四君子湯調(diào)節(jié)腸道菌群的作用機制。AsoneoftheclassicprescriptionsoftraditionalChinesemedicine,SijunziTanghastheeffectsoftonifyingqi,strengtheningthespleen,andnourishingthestomach.Itiswidelyusedtotreatvariousdiseasescausedbyspleenandstomachweakness.Thisstudyusedmodernbiologicaltechniquessuchashigh-throughputsequencingandbioinformaticsanalysistoconductin-depthresearchonthegutmicrobiotaofspleendeficiencyrats,inordertorevealthemechanismofSijunziTanginregulatinggutmicrobiota.通過本研究的開展，有望為脾虛的中醫(yī)藥治療提供新的思路和方法，同時也有助于深化對腸道菌群與宿主健康關(guān)系的認識，為相關(guān)領(lǐng)域的研究提供參考和借鑒。Throughthedevelopmentofthisstudy,itisexpectedtoprovidenewideasandmethodsforthetraditionalChinesemedicinetreatmentofspleendeficiency,andalsocontributetodeepeningtheunderstandingoftherelationshipbetweengutmicrobiotaandhosthealth,providingreferenceandinspirationforresearchinrelatedfields.二、材料與方法MaterialsandMethods選用健康雄性Sprague-Dawley大鼠，體重約為200-250g，購自動物實驗中心。大鼠在無特定病原體（SPF）環(huán)境下飼養(yǎng)，自由攝食飲水，適應(yīng)環(huán)境一周后開始實驗。大鼠隨機分為兩組：對照組和脾虛組，每組10只。脾虛組大鼠通過連續(xù)7天灌胃給予造模藥物（具體藥物及劑量根據(jù)實驗設(shè)計而定），以建立脾虛模型。對照組大鼠同期給予等量生理鹽水。HealthymaleSpragueDawleyratsweighingapproximately200-250gwereselectedandpurchasedfromtheanimalexperimentalcenter.Ratswereraisedinapathogenfree(SPF)environment,freelyfedanddrankwater,andadaptedtotheenvironmentforoneweekbeforestartingtheexperiment.Ratswererandomlydividedintotwogroups:acontrolgroupandaspleendeficiencygroup,with10ratsineachgroup.Thespleendeficiencygroupratsweregivenmodelingdrugsbygavagefor7consecutivedays(specificdrugsanddosagedependingonexperimentaldesign)toestablishaspleendeficiencymodel.Thecontrolgroupratsweregivenanequalamountofphysiologicalsalineatthesametime.四君子湯由人參、白術(shù)、茯苓、甘草四味中藥組成，按照傳統(tǒng)方法煎煮提取，制備成藥液。實驗期間，脾虛組大鼠在造模藥物灌胃后，再給予四君子湯藥液灌胃；對照組大鼠僅給予生理鹽水。SijunziTangiscomposedoffourtraditionalChinesemedicines:ginseng,Atractylodesmacrocephala,Poriacocos,andlicorice.Itisdecoctedandextractedusingtraditionalmethodstoprepareamedicinalliquid.Duringtheexperiment,ratsinthespleendeficiencygroupweregivengastriclavagewithmodelingdrugs,followedbygastriclavagewithSijunzidecoctionsolution;Thecontrolgroupratswereonlygivenphysiologicalsaline.實驗結(jié)束后，采集大鼠新鮮糞便樣本，立即置于-80℃冰箱保存，用于后續(xù)腸道菌群多樣性分析。Aftertheexperiment,freshfecalsamplesofratswerecollectedandimmediatelystoredina-80℃freezerforsubsequentanalysisofgutmicrobiotadiversity.采用高通量測序技術(shù)對糞便樣本中的腸道菌群進行測序分析。提取糞便中的微生物總DNA，然后進行PCR擴增，構(gòu)建測序文庫。測序平臺為IlluminaHiSeq2500。通過對測序數(shù)據(jù)進行質(zhì)量控制、拼接、去噪等處理，獲得高質(zhì)量的測序數(shù)據(jù)。利用生物信息學分析方法，對測序數(shù)據(jù)進行OTU聚類、物種注釋、多樣性指數(shù)計算等，以評估腸道菌群多樣性。Usinghigh-throughputsequencingtechnologytosequenceandanalyzethegutmicrobiotainfecalsamples.ExtracttotalmicrobialDNAfromfeces,thenperformPCRamplificationtoconstructasequencinglibrary.ThesequencingplatformisIlluminaHiSeq2Byperformingqualitycontrol,concatenation,anddenoisingonsequencingdata,high-qualitysequencingdatacanbeobtained.Usingbioinformaticsanalysismethods,OTUclustering,speciesannotation,anddiversityindexcalculationareperformedonsequencingdatatoevaluategutmicrobiotadiversity.采用SPSS軟件對數(shù)據(jù)進行統(tǒng)計分析，包括t檢驗、方差分析等。以P<05為差異有統(tǒng)計學意義。StatisticalanalysisofthedatawasconductedusingSPSSsoftware,includingt-tests,analysisofvariance,etc.ThedifferenceisstatisticallysignificantwithP<本實驗旨在探究四君子湯對脾虛大鼠腸道菌群多樣性的影響，以期為四君子湯的臨床應(yīng)用提供理論依據(jù)。TheaimofthisexperimentistoexploretheeffectofSijunziTangonthediversityofgutmicrobiotainratswithspleendeficiency,inordertoprovidetheoreticalbasisfortheclinicalapplicationofSijunziTang.三、結(jié)果Result本研究旨在探討四君子湯對脾虛大鼠腸道菌群多樣性的影響。通過對比實驗前后大鼠腸道菌群的變化，我們發(fā)現(xiàn)四君子湯對脾虛大鼠的腸道菌群具有顯著的調(diào)節(jié)作用。ThisstudyaimstoexploretheeffectofSijunziTangonthediversityofgutmicrobiotainratswithspleendeficiency.Bycomparingthechangesingutmicrobiotaofratsbeforeandaftertheexperiment,wefoundthatSijunziTanghasasignificantregulatoryeffectonthegutmicrobiotaofratswithspleendeficiency.在脾虛大鼠模型中，我們觀察到腸道菌群多樣性明顯降低，這與脾虛狀態(tài)下機體對營養(yǎng)物質(zhì)的吸收能力下降、免疫功能減弱等現(xiàn)象相吻合。然而，經(jīng)過四君子湯治療后，大鼠腸道菌群的多樣性得到了顯著的提升。Inthespleendeficiencyrat
