摘要
目的:探讨Sirt1?rs 2236319多态性与COPD遗传易感性的关系。方法研究对象为2014年3月至2015年3月从我院门诊或病房收集的149例COPD稳定期患者及160例我院同期健康查体者。应用实时 PCR检测 Sirt1?rs 2236319基因型分布频率,并比较人群中炎性因子水平,包括 IL-6及CRP。结果 COPD组及对照组 AA、AG、GG 基因型频率分别为59.1%(88/149)、35.6%(53/149)、5.4%(8/149)与45.0%(72/160)、48.8%(78/160)、6.3%(10/160),等位基因A、G频率分别为76.8%(229/298)、23.2%(69/298)与69.4%(222/320)、30.6%(98/320),组间比较差异均有统计学意义(χ2值分别为6.23、6.06,P均<0.05)。 COPD组中携带AA等位基因者IL-6及CRP水平均高于AG+GG等位基因携带者[(10.30±0.40)、(10.16±0.36) mmol/L,(2.56±0.20)、(2.46±0.22) mg/L],差异均有统计学意义( F值分别为4.52、8.04,P均<0.05);对照组中携带AA等位基因者IL-6及CRP水平与AG+GG等位基因携带者比较差异均无统计学意义( P均>0.05)。 COPD组携带AA等位基因或AG+GG等位基因的IL-6和CRP均高于对照组[(10.30±0.40)、(9.88±0.56) mmol/L,(10.16±0.36)、(9.86±0.57) mmol/L;(2.56±0.20)、(2.28±0.25) mg/L,(2.46±0.22)、(2.26±0.26) mg/L],差异均统计学意义(F值分别为34.52、11.09,73.06、19.38,P均<0.01)。结论 Sirt1?rs 2236319多态性与COPD易感性及炎症因子的高表达相关,其可能通过调节炎症反应参与COPD的发生发展。
Objective To explore the relationship between Sirt1 single nucleotide polymorphisms ( rs2236319 ) and chronic obstructive pulmonary disease ( COPD ) susceptibility. Methods The subjects included 149 patients with stable COPD in the First People′s Hospital of Jining outpatient or ward from March 2014 to March 2015, and 160 cases of the same period health check. Sirt1?rs 2236319 genotype distribution frequency was detected by real?time PCR,and the levels of inflammatory factors were compared,including IL-6 and CRP. Results The AA,AG,GG genotype frequency of COPD group were 59. 1%( 88/149) ,35. 6%( 53/149),5. 4%(8/149) respectively,of control group were 45. 0%(72/160),48. 8%(78/160),6. 3%(10/160) respectively,the allele A,G frequency of COPD group were 76. 8%(229/298),23. 2%(69/298) respectively,of control group were 69. 4%( 222/320 ) , 30. 6%( 98/320 ) respectively, there were statistically significant differences between the two groups(χ2=6. 23,6. 06,P〈0. 05) . IL-6 and CRP levels were significantly increased in COPD group carrying AA genotype as compared to COPD group carrying AG+GG genotype((10. 30±0. 40) mmol/L,(10. 16±0. 36) mmol/L;(2. 56±0. 20) mg/L,(2. 46±0. 22) mg/L;F=4. 52,8. 04,P〈0. 05);There were no significant differences in terms of IL-6 and CRP levels in control group carrying AA genotype as compared to control group carrying AG+GG genotype ( P〉0. 05 ) . Both the level of IL-6 and CRP were significantly increased in COPD group carrying AA genotype and AG+GG carriers compared to controls((10. 30 ± 0. 40 ) , ( 9. 88 ± 0. 56 ) mmol/L, ( 10. 16 ± 0. 36 ) , ( 9. 86 ± 0. 57 ) mmol/L;( 2. 56 ± 0. 20 ) , ( 2. 28±0. 25) mg/L,(2. 46±0. 22),(2. 26±0. 26) mg/L;F=34. 52,11. 09,73. 06,19. 38;P〈0. 01). Conclusion The polymorphisms of Sirt1?rs2236319 may be an additional risk factor for COPD and associate with inflammatory factors. Furthermore the involvement of rs2236319 in the initiation and progression of COPD may relate to inflammatory processes.
