| Outline of Final Research Achievements |
(1)Immunohistochemisty for FGFR1, VEGFR2, EGFR in the lungs of pulmonary venous obstructive hypertension(PVOD) showed higher expression of FGFR compared to VEGFR and EGFR in PVOD lungs. FGF-FGFR may pathway contribute the pathogenesis of PVOD. (2)Therapy related proteins such as PDE5、ER-A/B、PGI2、sGCα/βexpressed higher in pulmonary hypertension(PH) compared to controls, however there were no difference between Group 1-PH and Group 3-PH. These drugs contribute to dilate vessel wall in both types of PH. (3) Systemic sclerosis (Ssc) related PH showed denser fibrosis compared to SLE related PH and replacement myocardial fibrosis was demonstrated at the site of late gadolinium enchancement of MRI in Ssc patient.(4) FoxF1 mutation was detected in Alveolar capillary dysplasia related PH children and Heterozygous mutations in OAS1 were detected in infantile-onset pulmonary alveolar proteinosis with hypogammaglobulinemia. These genetic background relate to secondary PH.
