發(fā)布時間:2018-08-24 15:19
【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、風濕性關(guān)節(jié)炎等類似病癥。目的:探討富含細胞因子的自體血清制備方法并進行細胞因子分析。方法:采用了獲得專利的采血設(shè)備(內(nèi)含3 mm玻璃小珠)進行外周血采集,充分混勻后放置于37℃的恒溫培養(yǎng)箱內(nèi),進行24 h的恒溫孵育,最終分離過濾得到自體血清。測定白細胞介素1受體拮抗物、白細胞介素6、白細胞介素8、白細胞介素1β等細胞因子定量的濃度,并用細胞因子抗體芯片的檢測方法對36種細胞因子進行了半定量測定。結(jié)果與結(jié)論:(1)制備的自體血清中多種細胞因子濃度有明顯增加,其中,對緩解骨關(guān)節(jié)炎病癥起到關(guān)鍵作用的白細胞介素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;白細胞介素6質(zhì)量濃度由389.5 ng/L增加至2 802 ng/L,白細胞介素8由"未檢測到"增加至2 822 ng/L;(2)采用細胞因子抗體芯片的方法檢測制備的自體血清發(fā)現(xiàn),至少有10種細胞因子的含量發(fā)生了改變,大部分因子的變化趨勢是制備后增加,少數(shù)幾個因子呈下降的趨勢;(3)結(jié)果證明,制備的自體血清當中,含有大量的白細胞介素1受體拮抗物和多種細胞因子,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胞來到炎癥部位,加快炎癥反應(yīng)進程,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,
