2、stract】 AIM: To explore the doseeffect relationship of neuronprotective effect of different doses of  naloxone in patients with intracerebral hemorrhage. METHODS:  One hundred and twenty patients were randomly divided into 3 groups of 40 cases each: high dose (H), medium dose (M) and low d

3、ose (L) groups. The hematoma volume and edemazone areas, the level of neuron specific enolase (NSE) in serum, nervefunctiondefect score and the ADL score were examined at particular time respectively. RESULTS:  There were significant differences in the hematoma volume and edemazone area at diff

4、erent times points within a group (P0.001). However, among different groups, the hematoma volume of L group was larger than those of H and M groups at 10 d (P<0.001) and the edemazone area of L group was larger than that of M and H groups（P0.002). But at 20 d, there was no significant difference

5、in the hematoma volume and edemazone area among the 3 groups. There was an increase of NSE in serum at 12 h after hemorrhage in all the patients. Moreover, NSE significantly decreased at 20 d and there were significant differences among the groups. The level of NSE in H group was lower than that in

6、M group and that in M group was lower than that in L group（P<0.001）. The nervefunctiondefect scores of H group was higher than those of M group and L group at 20 d（P<0.02）. The ADL scores of H group was higher than that of M group and the score of M group was higher than that of L group at 3 m

7、o（P<0.001）. CONCLUSION:  Therapy with naloxone of 0.3 mg/(kgd) each day can protect neurons, decrease the function defect and improve living conditions in patients with intracerebral hemorrhage.【Keywords】 cerebral hemorrhage; Naloxone; doseresponse relationship, drug;  phosphopyruvate h

8、ydratase【摘要】 目的： 探討不同劑量納絡(luò)酮治療腦出血對(duì)其神經(jīng)功能保護(hù)作用的量效關(guān)系. 方法： 腦出血患者120例，隨機(jī)分為納絡(luò)酮高(H)、中(M)、低(L）劑量治療組，每組40例，分期測(cè)患者血腫體積和水腫帶面積、血清神經(jīng)元特異性烯醇化酶(NSE)水平，進(jìn)行神經(jīng)缺損及ADL評(píng)定. 結(jié)果： 資料完整患者H組32例、M組29例、L組34例.  3組組內(nèi)血腫體積和水腫帶面積隨時(shí)間變化有差異(P<0.001)；組間比10 d時(shí)血腫體積L組明顯>M組>H組(P<0.001)，水腫帶面積L組>M組>H組（P0.002)，但20 d組間血腫體積及水腫帶面

9、積均無(wú)差異； 出血后12 h內(nèi)患者血清NSE升高，20 d時(shí)明顯下降且組間比NSE值有差異（P<0.001），明顯H組<M組<M組<L組（PM組>L組（P<0.001）. 結(jié)論： 0.3 mg/（kgd）納絡(luò)酮治療具有更良好的保護(hù)患者神經(jīng)元、降低功能缺損、提高預(yù)后生活質(zhì)量的作用. 【關(guān)鍵詞】 腦出血；納絡(luò)酮；劑量效應(yīng)關(guān)系，藥物；磷酸丙酮酸水合酶0引言腦出血是一種致殘率極高的疾病，血腫及繼發(fā)缺血導(dǎo)致的神經(jīng)功能缺損給患者生活帶來(lái)極大的痛苦，保護(hù)神經(jīng)細(xì)胞是早期治療不可忽視的環(huán)節(jié). 近年發(fā)現(xiàn)納絡(luò)酮還具有非拮抗阿片受體作用，對(duì)穩(wěn)定腦出血后神經(jīng)元有一定的作用，

10、但目前還缺乏納絡(luò)酮的推薦劑量及相關(guān)實(shí)驗(yàn)支持1. 神經(jīng)元特異性烯醇化酶(neuron specific enolase, NSE)是神經(jīng)系統(tǒng)特異性蛋白質(zhì)，主要存在于大腦神經(jīng)元和神經(jīng)內(nèi)分泌細(xì)胞內(nèi)，當(dāng)其損傷或壞死后，NSE可溢入腦脊液和血液；腦膠質(zhì)細(xì)胞和其他神經(jīng)組織不含NSE，故它是檢測(cè)腦中神經(jīng)元壞死的客觀指標(biāo)2，3. 所以我們以不同劑量納絡(luò)酮早期治療腦出血，通過(guò)血清NSE的檢測(cè)和功能缺損等評(píng)定，評(píng)價(jià)納絡(luò)酮的量效關(guān)系.1對(duì)象和方法1.1對(duì)象200204/200404本院患者120例. 診斷依據(jù)第四屆全國(guó)腦血管病會(huì)議修訂標(biāo)準(zhǔn)，發(fā)病12 h內(nèi)入院，螺旋CT診斷為基底節(jié)區(qū)出血，出血量在1040 mL，排除
