| 摘 要：［目的］ 研究结直肠癌患者维生素D受体（VDR）表达对血浆促炎性因子以及肠道菌群的影响情况。［方法］ 纳入初次诊断为结直肠癌的患者130例和年龄、性别成组匹配的对照（无结直肠疾病的受检者）130名，采用免疫组化的方法测量结直肠癌患者癌组织中的VDR表达水平，并将患者分为VDR高表达组以及VDR低表达组。检测研究对象血浆中促炎性细胞因子白介素-6（IL-6）、C反应蛋白（CRP）和肿瘤坏死因子受体2（sTNFRⅡ）水平，对研究对象粪便样本中细菌的16S rDNA进行测序得到肠道菌群构成与丰富度。［结果］ VDR低表达组患者血浆sTNFRⅡ与CRP显著高于对照组（P<0.001）。VDR低表达组sTNFRⅡ显著高于VDR高表达组（P=0.027）。VDR低表达组与高表达组分别与对照组相比得到的差异细菌不同，VDR低表达患者体内Fusobacterium varium、Ruminococcus torques等6种细菌有显著升高。［结论］ 结直肠癌患者体内VDR受体表达可能影响了血浆促炎性因子和肠道菌群变化。 |

| Abstract：［Purpose］ To investigate the effects of vitamin D receptor(VDR) on plasma pro-inflammatory cytokine levels and the gut microbiome in colorectal cancer(CRC) patients.［Methods］ One hundred thirty CRC patients and 130 gender and age-matched healthy controls were included in the study. The expression of VDR protein in the tissue samples of 130 CRC patients was tested by immunohistochemical technique. The plasma levels of pro-inflammatory cytokines IL-6，C-reactive protein(CRP) and soluble tumor necrosis factor receptorⅡ(sTNFRⅡ) were examined. Composition and abundance of microbiota in stool were determined by 16S rDNA sequencing.［Results］ Among 130 patients，there were 74 patients with low expression of VDR［VDR(-) group］ and 56 patients with high expression of VDR［VDR(+) group］ . The plasma STNFRⅡ and CRP levels were significantly increased in VDR(-) group compared with control group(P<0.001). The level of sTNFRⅡ in VDR(-) group was significantly higher than that in VDR(+) group(P=0.027). The elevated abundance of Fusobacterium varium，Ruminococcus torques，and other four species was observed in VDR(-) group. ［Conclusion］ The expression of VDR in CRC patients may be associated with the changes in plasma pro-inflammatory cytokines and gut microbiota. |
