ABSTRACT
Objective To explore the expression status of carbonic anhydrase Ⅲ (CA Ⅲ) from quadriceps femoris muscle in two kinds of muscle clinical phenotype (skeletal muscle atrophy group and skeletal muscles non-atrophy group) of chronic obstructive pulmonary disease (COPD).Methods Totally 37 inpatients from our hospital,were divided into 11 patients without COPD and 26 patients with COPD,in addition,according to body mass index,fat free mass index and quadriceps cross-section diameter,patients with COPD were divided into 14 skeletal muscles non-atrophy patients (SMNA)and 12 skeletal muscle atrophy patients (SMA).CA Ⅲ concentration of femoris quadriceps specimens was quantitatively determined using Western blot methods,CA Ⅲ mRNA expression levels of femoris quadriceps specimens were also quantitatively measured using RT-PCR,then compared among the 3 groups.Results There was significant difference in CA Ⅲ quantitative concentration and CA Ⅲ mRNA expression level in each group (P < 0.05),further more,CA Ⅲ concentration expression level was significantly higher (P < 0.01)in SMA group (1.260 ± 0.068) than in SMNA group (1.110 ± 0.014),the latter was significantly higher (P < 0.01) than in the control group (1.000 ± O.062).CA Ⅲ mRNA expression level was significantly higher(P < 0.01) in SMNA group(2.170 ±0.412) than in the control group(1.000 ±0.115),and was significantly lower than in SMA group (3.770 ± 0.788 ; P < O.01).CA Ⅲ concentration and CA Ⅲ mRNA expression level increased at equal pace in SMNA group and SMA group,however,CA Ⅲ quantitative concentration and CA Ⅲ mRNA expression level were inconsistent in the two groups.Conclusion The expression status of CA Ⅲ in quadriceps femoris muscle was different in two kinds of muscle clinical phenotype of COPD.
