P3 Imbalance of endogenous hydrogen sulfide and homocysteine pathway in chronic obstructive pulmonary disease combined with cardiovascular disease

The pathogenesis of chronic obstructive pulmonary disease (COPD) combined with cardiovascular disease (CVD) is not fully identified. Endogenous hydrogen sulfide (H2S) play an important role in the pathophysiology of COPD. Homocysteine (Hcy) is an important substrate for the endogenous H2S production and also a risk factor for CVD. The present study is to explore the imbalance of endogenous H2S and Hcy metabolic pathway in patients with COPD...
