【摘要】:背景:自體血清療法是一種新興的、安全的生物療法,主要適應(yīng)證是骨關(guān)節(jié)炎、風(fēng)濕性關(guān)節(jié)炎等類(lèi)似病癥。目的:探討富含細(xì)胞因子的自體血清制備方法并進(jìn)行細(xì)胞因子分析。方法:采用了獲得專(zhuān)利的采血設(shè)備(內(nèi)含3 mm玻璃小珠)進(jìn)行外周血采集,充分混勻后放置于37℃的恒溫培養(yǎng)箱內(nèi),進(jìn)行24 h的恒溫孵育,最終分離過(guò)濾得到自體血清。測(cè)定白細(xì)胞介素1受體拮抗物、白細(xì)胞介素6、白細(xì)胞介素8、白細(xì)胞介素1β等細(xì)胞因子定量的濃度,并用細(xì)胞因子抗體芯片的檢測(cè)方法對(duì)36種細(xì)胞因子進(jìn)行了半定量測(cè)定。結(jié)果與結(jié)論:(1)制備的自體血清中多種細(xì)胞因子濃度有明顯增加,其中,對(duì)緩解骨關(guān)節(jié)炎病癥起到關(guān)鍵作用的白細(xì)胞介素1受體拮抗物的質(zhì)量濃度由平均140.25 ng/L增加至1 125 ng/L,增加8倍以上;白細(xì)胞介素6質(zhì)量濃度由389.5 ng/L增加至2 802 ng/L,白細(xì)胞介素8由"未檢測(cè)到"增加至2 822 ng/L;(2)采用細(xì)胞因子抗體芯片的方法檢測(cè)制備的自體血清發(fā)現(xiàn),至少有10種細(xì)胞因子的含量發(fā)生了改變,大部分因子的變化趨勢(shì)是制備后增加,少數(shù)幾個(gè)因子呈下降的趨勢(shì);(3)結(jié)果證明,制備的自體血清當(dāng)中,含有大量的白細(xì)胞介素1受體拮抗物和多種細(xì)胞因子,另外,自體血清中還含有一部分的趨化因子,提示這些趨化因子能夠招募更多的免疫細(xì)胞來(lái)到炎癥部位,加快炎癥反應(yīng)進(jìn)程,起到治療的作用。
[Abstract]:Background: autologous serum therapy is a new and safe biotherapy. The main indications are osteoarthritis, rheumatoid arthritis and other similar diseases. Objective: to investigate the preparation of cytokine-rich autologous serum and analyze cytokines. Methods: the peripheral blood was collected with patented blood collection equipment (containing 3 mm glass beads), and then was fully mixed and placed in a constant temperature incubator at 37 鈩,
