摘要
目的探讨腹腔镜下Roux-en-Y胃旁路术对2型糖尿病(T2DM)患者术后近期免疫功能的调节作用,并对该调节作用与血糖控制的关系进行初步探究。方法回顾性收集2014年1月至2015年1月在黑龙江省佳木斯大学糖尿病外科研究所行腹腔镜Roux-en-Y胃旁路术的28例2型糖尿病患者的病例资料,比较患者外周血空腹血糖(FBG)、糖化血红蛋白(HbAlc)和免疫球蛋白(IgG、IgA和IgM)水平以及各免疫细胞亚群[CD3+T淋巴细胞、CD3+CD8+杀伤型T细胞、CD3+CD4+辅助型T细胞、CD16+CD56+自然杀伤(NK)细胞亚群和CD19+CD45+B细胞亚群]比例的手术前后变化.并对手术前后免疫球蛋白水平及免疫细胞亚群比例与FBG和HbAlc水平进行相关性分析。结果T2DM患者术前FBG和HbAlc水平分别为(14.21±1.89)mmol/L和(9.96±0.97)%,术后均明显降低[分别为(5.784-1.15)mmol/L和(6.874-0.69)%,均P〈0.05]。术前免疫球蛋白IgG、IgM和IgA水平分别为(9.41±1.23)g/L、(1.71±0.22)g/L和(1.25±0.26)g/L,术后均明显升高[分别为(12.74±1.61)g/L、(2.43±0.39)g/L和(1.97±0.23)g/L,均P〈0.05]。术前CD3+T淋巴细胞、CD3’CD8’杀伤型T细胞和CD19+CD45+B细胞亚群比例分别为(55.3±3.8)%、(15.6±5.3)%和(8.4±3.7)%,术后亦明显升高f分别为(67.64-4.6)%、(28.7±4.2)%和(18.1±4.1)%,均P〈0.05]。但术后CD3+CD4+辅助型T细胞和CD16+CD56+NK细胞比例与术前水平的差异无统计学意义(均P〉0.05)。免疫球蛋白(IgG、IgM和IgA)水平、CD4+/CD8+比值及CD19+CD45+B细胞亚群比例与FBG和HbAlc水平均呈显著负相关(IgG与FBG:r=-0.865,IgA与FBG:r=-0.887,IgM与FBG:r=-0.902,CD4+/CD8+与FBG:r=-0.956,CD19+CD45’与FBG:r=~0.834;IgG与HBAlC:r=-0.859,IgA�
Objective To investigate the effect of laparoscopic Roux-en-Y gastric bypass on the short-term immune function of type 2 diabetic patients and to explore the correlation between the immune regulatory effect and blood glucose control. Methods Clinical data of 28 patients with type 2 diabetes mellitus who underwent laparoscopic Roux-en-Y gastric bypass surgery in our hospital during January 2014 to January 2015 were retrospectively collected. Fasting blood glucose (FBG), glycosylated hemoglobin (HbAlc), immunoglobulin (IgG, IgA, IgM), T lymphocytes CD3+, killer T cells CD3+CD8+, helper T ceils CD3+CD4+, natural killer(NK) ceil subsets CD16+,CD56+ and B cell subsets CD19+,CD45+ levels were detected and compared between before and after surgery. Correlation of immunoglobulin and immune cell subsets with the level of FBG and I-IbAlc were examined. Results After operation, FBG and HbAlc decreased significantly from (5.78±1.15) mmol/L to (14.21 ± 1.89) mmol/L, and (9.96 ± 0.97)% to (6.87 ±0.69)%, respectively (all P 〈 0.05), and immunoglobulin (IgG, IgA, IgM) increased significantly [IgG: from(9.41 ± 1.23) g/L to (12.74 ± 1.61) g/L, IgM: from (1.71 ± 0.22) g/L to (2.43 ± 0.39) g/L, IgA: from (1.25±0.26) g/L to (1.97 ± 0.23) g/L, all P 〈 0.05]. Besides, T lymphocytes CD3+, killer T cells CD3+CD8+ and B cell subsets CD19+CD45+elevated significantly as well IT lymphocytes CD3+: from (55.3 ± 3.8)% to (67.6 ±4.6)%, killer T cells CD3+CD8+: from (15.6±5.3)% to (28.7 ±4.2)%, B cell subsets CD19+CD45+: from (8.4 ± 3.7)% to (18.1 ± 4.1)%, respectively, all P 〈 0.05]. There was no significant difference in the expression of helper T cells CD3+CD4+ and natural killer cell subsets CD16+CD56+ between pre- operation and post-operation(all P〉 0.05). Levels of immunoglobulin (IgG, IgA, IgM), CD4+/CD8+ ratio and B cell subsets were negatively correlated with
