Objective:To explore therapeutic effect of Fasudil combined Salmeterol Xinafoate and fluticasone propio‐nate powder for inhalation (Seretide) on patients with chronic obstructive pulmonary disease (COPD) combined pul‐monary arterial hypertension (PAH ) .Methods :A total of 120 patients ,who hospitalized in our department from Jan 2013 to Oct 2014 and conformed to diagnostic standards of COPD and PAH ,were selected .According to ran‐dom number table ,they were equally divided into routine treatment group (received routine therapeutic measures ) , Fasudil group (received Fasudil based on routine treatment group ) and combined treatment group (received Fasudil combined Seretide based on routine treatment ) . Pulmonary function indexes , mean pulmonary arterial pressure (mPAP) ,pulmonary arterial systolic pressure (PASP) ,6min walking distance (6MWD) and blood gas indexes were observed and compared among three groups before and after treatment .Results:Compared with routine treatment group after treatment ,there were significant reductions in mPAP [(54.1 ± 10.3) mmHg vs .(51.3 ± 9.5) mmHg vs . (48.5 ± 10.5) mmHg] and PASP [ (72.4 ± 9.7) mmHg vs .(63.4 ± 9.3) mmHg vs .(61.6 ± 9.1) mmHg] ,and sig‐nificant rise in 6MWD [ (259.4 ± 37.0) m vs .(274.2 ± 36.5) m vs .(288.3 ± 47.5) m] ,forced expiratory volume in one second [FEV1 ,(1.44 ± 0.32) L vs .(1.59 ± 0.38) L vs .(1.87 ± 0.34) L] and FEV1/forced vital capacity (FVC) [ (47.2 ± 11.9)% vs .(50.3 ± 12.1)% vs .(54.6 ± 11.7)% ];significant rise in partial pressure of oxygen in artery [PO2 ,(64.3 ± 9.8) mmHg vs .(68.9 ± 8.2) mmHg vs .(76.9 ± 9.5) mmHg] and saturation of arterial blood oxygen [SaO2 ,(65.0 ± 8.2)% vs .(71.0 ± 9.8)% vs .(76.8 ± 9.4)% ] ,and significant reduction in partial pressure of carbon dioxide in artery [PCO2 ,(63.6 ± 9.5) mmHg vs .(58.5 ± 9.6) mmHg vs .(51.3 ± 7.9) mmHg] in Fasud‐il group and combined treatment group ,and those of combined treatment group were significantly improved com‐pared to those of Fasudil group , P<0.05 or <0.01. Actual base excess of combined treatment group was signifi‐cantly higher than the other two groups , P<0. 01 both . Conclusion:Fasudil combined Seretide can significantly im‐prove pulmonary function reduction ,improve PAH ,quality of life and prognosis in COPD + PAH patients .

Objective: To explore mechanism of fasudil combined salmeterol and fluticasone propionate powder for inhalation (Seretide) in treating chronic obstructive pulmonary disease (COPD) complicated pulmonary artery hypertension (PAH).Methods: A total of 120 patients accorded with diagnostic standards of COPD and PAH, who hospitalized in our department from Jan 2013 to Oct 2014, were selected.According to random number table method, patients were randomly and equally divided into routine treatment group, fasudil group (received intravenous drip of fasudil based on routine treatment group) and combined treatment group (received additional Seretide therapy based on fasudil group).Levels of nitric oxide (NO), endothelin-1 (ET-1), C reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were measured and compared among three groups before and after treatment.Results: Compared with before treatment, after two-week treatment, there were significant reductions in levels of CRP, ESR and ET-1, and significant rise in NO level in three groups, P<0.05 or<0.01;compared with routine treatment group after treatment, there were significant reductions in levels of CRP[(14.8±3.3) mg/L vs.(12.9±3.6) mg/L vs.(11.4±3.4) mg/L], ESR[(37.3±8.9) mm/h vs.(32.9±8.8) mm/h vs.(29.3±5.6) mm/h]and ET-1[(63.1±11.2) ng/L vs.(57.5±8.1) ng/L vs.(53.1±8.9) ng/L], and significant rise in NO level[(70.2±10.7) μmol/L vs.(76.0±8.0) μmol/L vs.(80.5±11.3) μmol/L]in fasudil group and combined treatment group, P<0.05 or<0.01;compared with fasudil group, there were significant reductions in levels of CRP, ESR and ET-1, and significant rise in NO level in combined treatment, P<0.05 all.Conclusion: Fasudil hydrochloride combined Seretide can significantly reduce levels of ESR, CRP and ET-1, and increase NO level in COPD + PAH patients.It may improve prognosis in these patients, which is worth extending.
