Efficacy and Effect on Serum inflammatory Factors, Vascular Endothelial Function and Pulmonary Function of Ulinastatin Combined with Ipratropium Bromide in the Treatment of AECOPD
Abstract Objective To observe the efficacy and effect on serum inflammatory factors, vascular endothelial function and pulmonary function of ulinastatin combined with ipratropium bromide in the treatment of AECOPD. Methods 125 cases of patients with AECOPD were randomly divided into observation group (64cases) and control group (61 cases).The control group were given ipratropium bromide based on conventional therapy，and the observation group were given ulinastatin based on the control group. After 1 week ,to observe the clinical efficacy and differences of serum inflammatory factors (hs-CRP, TNF-α, IL-1, IL-8), vascular endothelial function related indicators (ET-1, NO, TXB2, VEGF), and pulmonary function (TLC, PEF1, PEF25, PEF50) between the two group. Results ①Comparison of curative efficacy The observation group of excellence rate 48.43%, effective was rate 35.31%,inefficiency was 6.25%,and those of the control group was 29.51%,60.66%,9.84%. The clinical efficacy of the two groups showed significant difference(Z=-2.123 P=0.034);②Comparison of serum inflammatory factors The two groups of hs-CRP, TNF-α, IL-6, IL-8 were decreased with before (tobservation group =23.173,19.294,8.382,16.291 P=0.000,0.000,0.000,0.000;tcontrol group =19.385,16.732,6.713,13.185 P=0.000,0.000,0.000,0.000), and all indexs of the observation group improved more significantly than that of the control group, with statistical difference (t=5.419,5.184,4.893,7.241 P=0.000,0.002,0.006,0.000); ③Comparison of vascular endothelial function The two groups of NO, VEGF were decreased and ET-1,TXB2,were decreased with before (tobservation group=14.728、17.482,12.103,17.827 P=0.000,0.000,0.000,0.000;tcontrol group =11.745,12.483,6.386,12.097 P=0.000,0.000,0.000,0.000), and all indexs of the observation group improved more significantly than that of the control group, with statistical difference (t=9.182,18.831,6.271,11.382 P=0.000,0.000,0.000,0.000);④Comparison of vascular pulmonary function The two groups of TLC, PEF1, PEF25, PEF50 were increased with before (tobservation group =10.742,8.736,9.014,11.422 P=0.000,0.000,0.000,0.000;tcontrol group =7.618、6.801,7.194,8.275 P=0.000,0.000,0.000,0.000), and all indexs of the observation group improved more significantly than that of the control group, with statistical difference (t=5.402、4.927,4.238,5.701 P=0.009,0.011,0.019,0.003).Conclusion ulinastatin combined with ipratropium bromide has high efficacy in the treatment of AECOPD，and has the function of inhibiting inflammatory reaction,protecting vascular endothelial function and pulmonary function.
