[Abstract] Objective To investigate the therapeutic efficacy of micheliolide (MCL) in the DBA/1 mice CIA model. Methods 40 cases of 6 weeks of DBA/1 male mice were randomly divided into 4 groups. The normal control group (group Nor) did not receive any treatment, the other three groups were induced to arthritis model by using immunization grade bovine type Ⅱ collegen: 24 hours after the secondary immunization began to intraperitoneal injection by two days once, the positive control group (group MTX) was treated with methotrexate (MTX), the experiment group (group MCL) was treated with MCL, while the negative control group (group Con) was treated with DMSO. On the first intraperitoneal injection day, the four groups' mice on their weight and the evaluation of arthritis were began to test for once two days. Administration after having 28 times intraperitoneal injection was stopped for 4 times of test. The blood for mouse cytokine array test was taken, the mice were executed, the paws were taken and the pathology analysis was did. Results It was successed for building the CIA mice model; the result of weight test showed that there had no difference between each group (P > 0.05); the evaluation of arthritis displayed that the MCL group was lower than that in the group Con (P < 0.01) and higher than the group MTX (P < 0.01); the pathological result showed that the normal joint tissue present from the group Nor, the synovitis cell infiltration, the hyperplasia of synovial cell, formation of granulation tissue and the necrotic tissue are present in the group Con, while the group MCL and the group MTX only presented synovitis cell infiltration, the hyperplasia of synovial cell and so on, and both of them were milder than the group Con; there were six cytokines tested in this experiment, and they were marked as 1 to 6. Cytokine 1 to 6 were all shown in the four groups, they were C5/C5a, TIMP-1, M-CSF, sICAM-1, IFN-γ, BLC. The result of M-CSF and TIMP-1 are the same to C5/C5a, which were lower in the group Con mice with arthritis, all of them had recovery at different degrees in the group MCL (P < 0.01); BLC only presented in the MCL group. Conclusion MCL has therapeutic effect on arthritis and C5/C5a, TIMP-1, M-CSF, BLC may contribute to this procedure.

類風(fēng)濕性關(guān)節(jié)炎(rheumatoid arthritis,RA)是一種全身性自身免疫性疾病,主要表現(xiàn)為慢性、對(duì)稱性、進(jìn)行性多關(guān)節(jié)炎[1]。類風(fēng)濕性關(guān)節(jié)炎以關(guān)節(jié)滑膜炎為特征,反復(fù)持久發(fā)作,可導(dǎo)致關(guān)節(jié)內(nèi)軟骨和骨破壞,關(guān)節(jié)功能障礙,甚至殘廢。類風(fēng)濕性關(guān)節(jié)炎發(fā)病呈全球性分布,我國的發(fā)病率為0.32%~0.36%[2]。目前副作用較小的治療類風(fēng)濕關(guān)節(jié)炎的藥物不多,相關(guān)藥物還有待于進(jìn)一步研究。
含笑內(nèi)酯(micheliolide,MCL)是近幾年研究者從70多種藥物中篩選出來的一種小分子化合物,其主要成分為倍半萜內(nèi)酯[3],它可以用小白菊內(nèi)酯為原料,在一定的溶劑和溫度下反應(yīng)得到[4]。含笑內(nèi)酯衍生于小白菊內(nèi)酯,其活性與小白菊內(nèi)酯相當(dāng),但它在血漿中穩(wěn)定性比小白菊內(nèi)酯高,成本比小白菊內(nèi)酯低[5],因此更適于作為臨床藥物研究。在此次研究中,筆者構(gòu)建了類風(fēng)濕關(guān)節(jié)炎DBA/1小鼠模型,并用MCL和MTX來治療小鼠,從而探究MCL對(duì)類風(fēng)濕關(guān)節(jié)炎的治療效果是否可靠。同時(shí)應(yīng)用蛋白芯片,檢測(cè)MTX治療后小鼠血清中細(xì)胞因子的變化。現(xiàn)報(bào)道如下:

3 討論
類風(fēng)濕關(guān)節(jié)炎是一種全身性慢性侵蝕性關(guān)節(jié)炎為特征的自身免疫病[12],病變特點(diǎn)為滑膜炎,以及由此造成的關(guān)節(jié)軟骨和骨質(zhì)破壞,最終導(dǎo)致關(guān)節(jié)畸形。該病分布于世界各地,未經(jīng)正規(guī)治療,約75%的患者會(huì)在3年之內(nèi)致殘。類風(fēng)濕關(guān)節(jié)炎的治療方法有理療、藥物治療、外科手術(shù)等。其中藥物治療又包含非甾體抗炎藥、慢性抗風(fēng)濕藥、促腎上腺皮質(zhì)激素、生物制劑和中草藥等多種藥物,然而目前為止,還沒有哪種藥物不但可以很好的治療類風(fēng)濕關(guān)節(jié)炎而且還具有很小的毒副作用[13]。
MCL是新近研究出的小分子化合物。在此次實(shí)驗(yàn)中,筆者通過建立類風(fēng)濕關(guān)節(jié)炎DBA/1小鼠模型,探究了MCL對(duì)類風(fēng)濕關(guān)節(jié)炎的治療作用。通過對(duì)四組小鼠的體重檢測(cè)、關(guān)節(jié)炎評(píng)價(jià)、病理切片觀察以及血清內(nèi)細(xì)胞因子檢測(cè),得知在整個(gè)實(shí)驗(yàn)過程中,小鼠的體重并未受到藥物治療的影響,表明MCL沒有干擾小鼠的正常生活狀態(tài)。關(guān)節(jié)炎評(píng)價(jià)中足掌厚度結(jié)果、關(guān)節(jié)炎評(píng)分結(jié)果均與病理切片評(píng)分結(jié)果一致,均顯示為MCL組小鼠整體得分低于Con組,處于MTX組和Con組之間,此結(jié)果證明MCL在治療類風(fēng)濕關(guān)節(jié)炎方面確實(shí)有一定的療效。在小鼠血清細(xì)胞因子檢測(cè)結(jié)果中, C5/C5a在Nor組中表達(dá)量最高,MTX組次之,MCL組接近與MTX組,而C5/C5a是機(jī)體免疫應(yīng)答的一部分在適應(yīng)性免疫中有一定的作用[14],提示MCL同MTX一樣均具有幫助機(jī)體恢復(fù)免疫調(diào)節(jié)功能的作用。TIMP-1為基質(zhì)金屬蛋白酶抑制因子,基質(zhì)金屬蛋白酶(MMPs)是一類降解細(xì)胞外基質(zhì)的一類多肽家族,其高表達(dá)能促進(jìn)細(xì)胞遷移和增殖[15-16]。在此實(shí)驗(yàn)中,MCL組和MTX組中TIMP-1的表達(dá)水平與Nor組幾乎一致,提示含笑內(nèi)酯有效的抑制了相應(yīng)細(xì)胞的遷移和增殖,對(duì)類風(fēng)濕關(guān)節(jié)炎起到了一定的治療作用。M-CSF為巨噬細(xì)胞集落刺激因子,是迄今為止發(fā)現(xiàn)的直接參與破骨細(xì)胞分化的兩種細(xì)胞因子之一。破骨細(xì)胞是骨細(xì)胞的一種,分解骨組織,行使骨吸收的功能,與成骨細(xì)胞在功能上相對(duì)應(yīng),二者協(xié)同,在骨骼發(fā)育和形成過程中發(fā)揮著重要的作用[17-18]。此實(shí)驗(yàn)中,MCL組的M-CSF水平與略高于Con組,MTX組接近與Nor組且均較前兩組高,表明MTX都能夠在一定程度上恢復(fù)M-CSF的表達(dá)情況,從而在一定程度上恢復(fù)骨組織的自我調(diào)節(jié)能力,而MCL的療效略低于MTX。MCL組中sICAM-1的表達(dá)水平低于其他各組,表明MCL對(duì)一些細(xì)胞的穩(wěn)定調(diào)節(jié)能力不是很強(qiáng),MCL組出現(xiàn)了BLC的表達(dá),說明MCL具有一定的免疫調(diào)節(jié)功能。
綜上所述,MCL具有一定的免疫調(diào)節(jié)功能,能夠在一定程度上幫助機(jī)體恢復(fù)免疫調(diào)節(jié)功能。C5/C5a,TIMP-1等細(xì)胞因子可能在MCL對(duì)類風(fēng)濕關(guān)節(jié)炎的調(diào)節(jié)中起到一定的作用。
