The flavin-containing monooxygenase 3 (FMO3) is an important hepatic microsomal enzyme. Numerous mutations of FMO3 gene have been reported, and polymorphic varients of the gene have been identified. Several studies indicated that variability in the expression of FMO3 involved in some nitrogen, or sulfur-containing durg metabolism. This review summarizes the genetic polymorphism of FMO3 and its role in drug metabolism and toxicity.

Objective To explore the relationship between self- management and DOSE index for patients with chronic obstructive pulmonary disease (COPD). Methods The convenient sampling and Pearson correlation analysis was used in the study,a total of 81 patients was investigated with Self- Management Scale (SMS) for COPD patients and DOSE index. Results The relationship of symptom management and DOSE index for COPD patients was a positive correlation (r=0.259, P<0.05);with self- efficacy was a negative correlation(r=-0.288, P<0.05).But self- management, daily life management, emotion management and information management with DOSE index were no correlation (P>0.05). Conclusions Through health education, nurses should strengthen to effectively help patients manage symptoms, enhance self- efficacy, improve the patients′quality of life.
