2、性脑出血模型。针刺组造模成功后进行头针治疗(位置相当于人体“百会”透“太阳”穴)。两组分别在造模前、造模后即刻和针刺后即刻通过磁共振波谱分析(MRS)和磁共振灌注加权成像(PW1)观察N一乙酰基天门冬氨酸(NAA)、平均通过时间(MTT)、相对脑血容量(rCBV)和相对脑血流量(rCBF)的变化。结果:与本组造模前比较,造模后两组血肿周围脑组织NA肌酸(cr)降低,MTT延长,rCBV和rCBF降低(P<0.05),两组间同期比较差异无统计学意义。疗后针刺组MT瞒短(P3、,且与模型组同期比较差异显著(P<0.05),而NAMCr无显著变化。结论:头穴透刺法对改善急性脑出血局部脑组织血流动力学改变具有显著的即刻效应,这可能是针刺对脑出血即刻效应产生的机制之一。关键词:头穴透刺,针刺;磁共振波谱分析;磁共振灌注加权成像;脑出血基金资助:国家自然基金课题(No.90709030)InstanteffectofacupuncturetoacuteintracerebralhemorrhagerabbitsstudiedbyPWIandMRSWANGFan,BAOChun.1ing4、,JIAOZhi.hua,DONGGui—rong,LEIHui.shu,ZHANSong.hua,LIHuan。huan.ZHAOXi(AcupunctureandMoxibustionDepartment,YueyangHospitalofIntegratedTraditionalChineseandWesternMedicineShanghmUniversityofChineseMedicine,Shanghai200437,China;RadiologyDepartment,ShuguangHos5、pitalofUniversityofChineseMedicine,Shanghai201203,China)Abstract:Objective:Toobservetheregularityforimmediatechangeofhemodynamicsandneuralmaterialmetabolismonbraintissuesofintracerebralhemorrhagerabbitafteracupuncturetreatment,exploringthemechanismofthein6、stanteffectsofacupuncture.Methods:Atotalof20NewZealandrabbitswererandomlydividedintomodelgroupandacupuncturegroup,with10casesineachgroup.Self-arterialinjectionmethodhadbeenusedtocopytheICHrabbitmode1.Afterthe1CHrabbitmodelwassuccessfullyestablished,theacu7、puncturegroupwastreatedonscalpacupointofhemorrhageside,equivalenttoBaihui(GV20)throughTaiyang(EX—HN5)inhumanbody.Quantitativeanalysisof1H—MRS(MagneticResonanceSpectroscopy)andPWI(PerfusionWeigtedImaging)wereusedtOobservetheMTT,rCBV,rCBFandcontentofNAAandC8、rinperihematomatissuesbefore,instantlyand1hourafterICHmodelwassuccessfullyestablished.Results:AftertheICHmodelwasestablished,NAA/Crleveldecreasedmarkedly,MTTextended,andrCBVandrCBFreducedsignificantly(P<0.05)inbothg
