ABSTRACT
OBJECTIVE@#To study the mRNA expression of muscle phenotype and collagen of soft palate and pathology in obstructive sleep apnea hypopnea syndrome (OSAHS).@*METHOD@#We used the Real-time PCR to test the mRNA expression of soft palate muscle myosin heavy chain (MyHC) phenotype and collagen in 12 OSAHS patients and 8 control patients. We also distinguished the muscle isoforms I , II with ATPase staining, then counted the numbers of isoforms muscle fiber.@*RESULT@#The mRNA expression of OSAHS group was more than control group in II A MyHC phenotype (P<0.01). The number of OSAHS group muscle fibre I isoform was less than control group with pH4. 3 ATPase staining (P<0.05).@*CONCLUSION@#Compare to control group, the enhancement happened in the mRNA expression of II A MyHC phenotype which can increase the velocity and power but de crease the enduring quality of muscle in OSAHS, and the reduce be in the I MyHC isoform of muscle fiber that can cause muscle velocity become slower and persistency become longer in OSAHS patients.
