Methods: Thirty-one patients with HPH were enrolled for IPH group, 16 males and 15 females, aged (65.19 ± 5.86) years;and 30 healthy people were enrolled for control group (NC group), 15 males and 15 females, aged (63.47 ± 6.16) years. The peripheral blood samples were collected and the mRNA expressions of G2A and OGR1 were determined by using real-time fluorescent quantitative PCR. The pulmonary arterial pressure (PAP) of HPH group was detected with echocardiography for the analysis of blood gas and pulmonary function testing. Human peripheral blood was collected to detect the mRNA levels of G2A, OGR1 and the serum levels of tumor necrosis factor-α (TNF-α). Results: PaCO2 was increased significantly in HPH group than that in NC group (p < .05). The percentage of forced expiratory volume in 1 s in predicted value (FEV1 pro%) and the ratio of FEV1/forced vital capacity (FVC) in HPH group were significant lower than those in NC group (p < .05). The expressions of peripheral blood G2A mRNA and TNF-α in HPH group were increased dramatically than those in NC group (p < .05). The expressions of OGR1 mRNA in peripheral blood had no difference between HPH group and NC group. The expressions of G2A mRNA and TNF-α in HPH group were positively related to pulmonary artery pressure significantly. Conclusions: The expression of proton-sensing receptor G2A and the level of TNF-α were increased in peripheral blood cells of patients with pulmonary hypertension. The expressions of TNF-α and G2A had positive correlations with pulmonary artery pressure.展开更多
