求翻译：随后我们应用RT-PCR技术测定了两组间混合淋巴细胞悬液中IL-21因子表达水平，结果发现实验组中IL-21的水平明显高于对照组，因此我们得出术后抗体水平的增高可能通过IL-21因子表达增加来达到的，这与已经有很多文献报道IL-21对B细胞产生抗体的促进作用相符[9, 10]。但IL-21的分泌不仅仅是Tfh分泌所独有，还有其他细胞，如Th17细胞，分泌IL-21，因此IL-21升高的具体机制还要进一步实验证实；是什么意思？

Then we apply the rt-pcr technique il, in the mixed lymphocyte suspension between the two groups-21 factor expression levels were determined and found that the levels were significantly higher in the experimental group in il, 21, so we have come to postoperative antibody levels increased may increas

Subsequently, we apply technology PCR RT - measured between the two groups in mixed lymphocyte suspension IL - 21 level factor is expressed, we have found that the experimental group IL - 21 significantly higher level than the control group, so we conclude that after antibody levels may be through I

Afterwards we applied the RT-PCR technology to determine during two groups to mix the lymphocyte to hang in the fluid the IL-21 factor expression level, finally discovered in the experimental group the IL-21 level was higher than the control group obviously, after therefore we obtained the technique
