摘　　要：目的:探讨在过载静压应力下益肾活血通络方含药血清对人椎间盘髓核细胞凋亡的影响及其相关机制。方法:将人椎间盘髓核细胞分为3组,空白组无任何干预,模型组和中药血清干预组在体外3 MPa压应力干预下作用2、4、6 h后,观察椎间盘髓核细胞的形态、生长状况、超微结构的变化及差异;检测椎间盘髓核细胞的凋亡率及髓核细胞内核因子κB p65(nuclear factor kappa-B p65,NF-κB p65),Y染色体中性别决定区相关的高迁移率组框9(SRY-related high mobility group-box 9,SOX9),C/EBP同源蛋白(C/EBP-homologous protein,CHOP),基质金属蛋白酶-13(matrix metalloprotein-13,MMP-13)蛋白和相对应基因表达情况。结果:同一作用时间下模型组髓核细胞与空白组比较:体积缩小、胞浆减少、生长状况更差;中药血清干预组髓核细胞较模型组体积稍大,形态保存更完整,胞浆更丰富,生长状况更好。同一作用时间下空白组髓核细胞超微结构完整,主级突起、次级突起结构未见断裂,模型组与中药血清干预组超微结构破坏,主级突起、次级突起可见不同程度断裂,两组超微结构未见明显差异。相同作用时间下模型组髓核细胞凋亡率高于空白组,而中药血清干预组髓核细胞凋亡率低于模型组(P<0.05);随作用时间增加,空白组、中药血清干预组椎间盘髓核细胞凋亡率未见明显差异,模型组椎间盘髓核细胞凋亡率增加。相同作用时间下,中药血清干预组较模型组NF-κB p65、CHOP、MMP-13表达减少,SOX9表达增多(P<0.05);随作用时间的增加,空白组、模型组髓核细胞的NF-κB p65、CHOP、MMP-13表达增多,SOX9表达减少,且模型组表达程度较空白组大(P<0.05);通过基因表达总体来看,在相同作用时间下,中药血清干预组髓核细胞基因NF-κB p65、CHOP、MMP-13相对定量较模型组均减少,而SOX9相对定量增多(P<0.05);空白组髓核细胞基因NF-κB p65、CHOP、MMP-13相对定量比�Objective:To explore the efficacy of Yishen Huoxue Tongluo(益肾活血通络)decoction containing serum on the apoptosis of human disc nucleus pulposus cells under the overload static pressure stress and its related mechanism.Methods:Human nucleus pulposus cells were divided into three groups.The blank group had no intervention.The model group and traditional Chinese medicine serum intervention group were treated with 3 MPa compressive stress in vitro for 2,4 and 6 hours.The changes and differences of morphology,growth status and ultrastructure of intervertebral disc nucleus pulposus cells were observed.The apoptosis rate of nucleus pulposus cells and nuclear factor kappa-B p65(NF-κB p65),SRY-related high mobility group-box 9(SOX9),C/EBP-homologous protein(CHOP),matrix metalloprotein-13(MMP-13)and corresponding gene expression were detected.Results:At the same time,compared with the blank group,the nucleus pulposus cells in the model group were smaller in volume,less in cytoplasm and worse in growth;the nucleus pulposus cells in the traditional Chinese medicine serum intervention group were slightly larger in volume,more complete in morphology,richer in cytoplasm and better in growth.Under the same action time,the ultrastructure of nucleus pulposus cells in blank group was complete,and the structures of primary and secondary processes were not broken;and the ultrastructure of model group and traditional Chinese medicine serum intervention group were damaged,the main and secondary processes were broken to varying degrees,and there was no significant difference between the two groups.At the same time,the apoptosis rate of nucleus pulposus cells in model group was higher than that in blank group,while the apoptosis rate of nucleus pulposus cells in the traditional Chinese medicine serum intervention group was lower than that in model group,the difference was statistically significant(P<0.05);with the increase of action time,there was no significant difference in the apoptosis rate of nucleus pulposus cells between
