目的:探讨经导管肝动脉化疗栓塞( TACE)联合超声引导经皮穿刺微波凝固治疗( PMCT)对原发性肝癌( PHC )治疗前后外周血 Th22细胞数量和功能的变化,并探讨其意义。方法流式细胞术分别检测PHC初诊组(治疗前组)、治疗有效组Th22细胞数量和功能的变化及正常对照组外周血中Th22细胞所占比例,同时检测胞内IL-22水平。酶联免疫吸附实验( ELISA)检测各组外周血中IL-22、TGF-β、TNF-α、IL-6的水平。半定量RT-PCR检测各组外周血中IL-22 mRNA的表达水平。并逐层分析比较。结果 PHC治疗前组和治疗后组Th22细胞比例、胞内IL-22平均荧光强度及外周血IL-22、TNF-α、IL-6、IL-22 mRNA的表达水平分别为(0.48±0.20)%、17.48±8.26、(10.86±3.16) ng/L、(122.73±29.41) ng/L、(60.96±12.84) ng/L、0.22±0.05和(0.86±0.24)%、31.62±16.36、(15.16±4.07) ng/L、(146.37±33.42) ng/L、(86.15±19.86) ng/L、0.34±0.07,均明显低于正常对照组的(1.24±0.31)%、56.53±27.34、(19.72±6.55) ng/L、(238.32±50.41) ng/L、(137.95±27.08)ng/L、0.47±0.09,差异有统计学意义(P<0.05);治疗前组Th22细胞比例、胞内IL-22平均荧光强度及外周血IL-22、TNF-α、IL-6、IL-22 mRNA的表达水平均低于治疗后组,差异有统计学意义(P<0.05);治疗前组和治疗后组TGF-β水平分别为(31.47±7.84)ng/L、(21.67±6.02)ng/L明显高于正常对照组(9.65±2.78)ng/L,差异有统计学意义(P<0.05)且治疗前组TGF-β的水平高于治疗后组( P<0.05)。结论 PHC患者体内Th22细胞数量减少、功能减低,经TACE联合PMCT治疗有效后得以一定程度恢复。 PHC患者体内TNF-α、IL-6的表达减低及TGF-β的过度表达可能抑制Th22细胞的分化发育及功能。
目的:探討經導管肝動脈化療栓塞( TACE)聯閤超聲引導經皮穿刺微波凝固治療( PMCT)對原髮性肝癌( PHC )治療前後外週血 Th22細胞數量和功能的變化,併探討其意義。方法流式細胞術分彆檢測PHC初診組(治療前組)、治療有效組Th22細胞數量和功能的變化及正常對照組外週血中Th22細胞所佔比例,同時檢測胞內IL-22水平。酶聯免疫吸附實驗( ELISA)檢測各組外週血中IL-22、TGF-β、TNF-α、IL-6的水平。半定量RT-PCR檢測各組外週血中IL-22 mRNA的錶達水平。併逐層分析比較。結果 PHC治療前組和治療後組Th22細胞比例、胞內IL-22平均熒光彊度及外週血IL-22、TNF-α、IL-6、IL-22 mRNA的錶達水平分彆為(0.48±0.20)%、17.48±8.26、(10.86±3.16) ng/L、(122.73±29.41) ng/L、(60.96±12.84) ng/L、0.22±0.05和(0.86±0.24)%、31.62±16.36、(15.16±4.07) ng/L、(146.37±33.42) ng/L、(86.15±19.86) ng/L、0.34±0.07,均明顯低于正常對照組的(1.24±0.31)%、56.53±27.34、(19.72±6.55) ng/L、(238.32±50.41) ng/L、(137.95±27.08)ng/L、0.47±0.09,差異有統計學意義(P<0.05);治療前組Th22細胞比例、胞內IL-22平均熒光彊度及外週血IL-22、TNF-α、IL-6、IL-22 mRNA的錶達水平均低于治療後組,差異有統計學意義(P<0.05);治療前組和治療後組TGF-β水平分彆為(31.47±7.84)ng/L、(21.67±6.02)ng/L明顯高于正常對照組(9.65±2.78)ng/L,差異有統計學意義(P<0.05)且治療前組TGF-β的水平高于治療後組( P<0.05)。結論 PHC患者體內Th22細胞數量減少、功能減低,經TACE聯閤PMCT治療有效後得以一定程度恢複。 PHC患者體內TNF-α、IL-6的錶達減低及TGF-β的過度錶達可能抑製Th22細胞的分化髮育及功能。

Objective To investigate the proportion and function of Th22 cells in patients with primary hepatic carcinoma ( PHC ) before and after treatment with transcatheter hepatic arterial chemoembolization ( TACE ) combined percutaneous microwave coagulation injection therapy ( PMCT ) and evaluate the significance of Th22 cells in PHC.M ethods The proportion and function of Th22 cells and intracellular IL-22 in the peripheral blood of PHC patients before therapy ( group 1 ) , PHC patients after therapy(group 2)and healthy donors(group 3)were evaluated by flow cytometry.The cytokines IL-22,TGF-β,TNF-αand IL-6 of each group were measured by enzyme-linked immunosorbent assay( ELISA) .The level of IL-22 mRNA of each group was examined by reverse transcription-PCR ( RT-PCR ) .Results The percentage of Th22 cells,mean fluorescence intensity of intracellular IL-22 and the level of IL-22,TNF-α,IL-6 and IL-22 mRNA in group l[(0.48 ±0.20)%,17.48 ±8.26,(10.86 ±3.16)ng/L,(122.73 ±29.41) ng/L,(60.96 ±12.84) ng/L,0.22 ±0.05] and group 2 [(0.86 ±0.24)%,31.62 ±16.36,(15.16 ± 4.07)ng/L,(146.37 ±33.42) ng/L,(86.15 ±19.86) ng/L,0.34 ±0.07] were significantly lower than thoes in group 3 [(1.24 ±0.31)%,56.53 ±27.34,(19.72 ±6.55) ng/L,(238.32 ±50.41) ng/L, (137.95 ±27.08)ng/L,0.47 ±0.09],and the differences were statistically significant(P <0.05).The percentage of Th22 cells,mean fluorescence intensity of intracellular IL-22 and the level of IL-22,TNF-α,IL-6 and IL-22 mRNA in group l was lower than those in group 2, and the differences were statistically significant(P<0.05).But the level of TGF-βin group l [(31.47 ±7.84) ng/L] and group 2 [(21.67 ± 6.02)ng/L] was significantly higher than that in group 3 [(9.65 ±2.78) ng/L] and the difference was statistically significant(P<0.05).The level of TGF-βin group 1 was higher than that in group 2(P<0.05). Conclusions The number and function of Th22 cells are reduced in PHC patients and recover after TACE combined with PMCT treatment.The lower level of TNF-α,IL-6 and overexpression of TGF-βin PHC patients might suppress the differentiation and function of Th22 cells.
