[Abstract]:Objective: To investigate the expression of NOD2m RNA in the nucleus of peripheral blood mononuclear in COPD patients and the determination of IL-6 concentration in serum, and to explore the role of NOD2 in the inflammatory mechanism of COPD patients according to the expression of NOD2 m RNA in the peripheral mononuclear nuclei of peripheral blood and the correlation between the serum IL-6 concentration and the pulmonary function in the peripheral blood mononuclear nuclei of different groups of patients. Methods: the COPD patients in the Department of respiratory medicine of Affiliated Hospital of Chuanbei Medical College from October 2013 to April 2014 were studied. According to the pulmonary function (FEV1/FVC%, FEV1 accounted for estimated%), the symptoms (m MRC respiratory difficulty index), the acute aggravation times of the past 1 years were evaluated comprehensively, and the patients were divided into groups of A, B, C, D four groups. 30 people in each group. 30 cases of health check in the same period were used as the healthy control group. The peripheral blood samples of each group and the control group were collected. The expression of NOD2 m RNA in the nucleus of peripheral blood mononuclear cells was measured by real-time fluorescence quantitative polymerase chain reaction (PCR), and the concentration of IL-6 in the specimens was measured by ELISA. The NOD2 of different groups of COPD patients was compared and analyzed. The expression of M RNA and the change of IL-6 concentration were used to investigate the relationship between the NOD2 m RNA expression and the concentration of IL-6 and the severity of COPD group and the correlation between the two. Results (1) the NOD2 m in the peripheral blood mononuclear nuclei of the COPD stable group and the healthy control group was 0.31 + 0.07, respectively, and the stability group was significantly higher than that of the healthy pair. The difference was statistically significant (P0.01). The concentration of serum IL-6 in patients with COPD stable period and healthy control group was 10.62 + 5.01pg/ml, 3 + 0.40pg/ml, and COPD stable period was significantly higher than that in healthy control group (P0.01). (P0.01), A, B, C, D groups and healthy controls. RNA was 0.18 + 0.10,0.18 + 0.08,0.36 + 0.11,0.51 + 0.17,0.10 + 0.07 respectively, A, B, C, and D group compared with the healthy control group, the difference was significantly higher than that between the 22 groups. There was no statistical significance (P0.01), and there was no significant difference between group A and B group (P0.05). (3) the serum IL-6 concentration of A, B, C, D and healthy control group was 6.36 + 1.82pg/ml, 6.52 + 1.97pg/ml, 12.12 +, 17.50 +, 3 +. 0.01) compared with A, B, C, D, the expression of IL-6 concentration in D group was significantly higher than that of C group, and the difference was statistically significant (P0.01). The IL-6 concentration in the C group was significantly higher than that of the A group and the group, the difference was statistically significant. There was a positive correlation with the increase of serum IL-6 concentration, and the correlation coefficient was r=0.82, the correlation was statistically significant (P0.01), the expression of NOD2 m RNA in.COPD stable patients was negatively correlated with the estimated value of FEV1, the correlation coefficient was r=-0.85, and the correlation was statistically significant (P0.01).COPD regular patients were negatively correlated with the expected value%. The correlation was statistically significant (P0.01). Conclusion (1) the NOD2 m RNA expression of NOD2 receptor in COPD patients and IL-6 concentration was significantly higher than that of the healthy control group. It was suggested that NOD2 and IL-6 participated in the COPD occurrence and development. There was a positive correlation between the expression of NOD2 m RNA and the IL-6 concentration in COPD groups, which may interact to promote inflammatory response.
