Objective To investigate the availability and safety of pulmonary rehabilitation for hospitalized patients with acute exacerba-tion of chronic obstructive pulmonary disease (COPD). Methods Seventy-two hospitalized patients with acute exacerbation of COPD were randomly included into test group (n=36) and control group (n=36) from June, 2015 to June, 2016. All the patients accepted management of anti-infection, phlegm elimination, antiasthma, etc., as well as the guidance of expectoration and health education; while the test group ac-cepted pulmonary rehabilitation from the third day of admission to discharge. Their strength of hand grip, 1-minute sit-to-stand test (STST), the days of hospitalization, lung function parameters, modified Medical Research Council (mMRC) scores and COPD Assessment Test (CAT) scores were measured before and after treatment. Results Compared with the control group, the strength of hand grip (t=2.985, P<0.01) and number of STST (t=2.024, P<0.05) increased, while the scores of CAT (t=3.222, P<0.01) and mMRC (t=2.212, P<0.05) de-creased in the test group. The hospital stay seemed to be shorter in the test group than in the control group, but there was no significant dif-ference (t=1.433, P>0.05). There was no significant difference in lung function after treatment in both groups (Z<1.031, P>0.05). Conclu-sion Pulmonary rehabilitation is effective on hospitalized patients with acute exacerbation of COPD in muscle strength, capability of activi-ties, and relieve the symptoms.

Objective To investigate whether FTO gene SNP polymorphisms were associated with metabolic traits in Chinese children. Methods A total of 595 children aged between 6 and 17 years were enrolled. The five common SNPs in the FTO gene(rs1421085,rs17817449,rs8050136,rs3751812 and rs9939609)were genotyped. Metabolic compo-nents and insulin were measured. Results (1)The obese patients showed the components of the metabolic traits were significant difference compared to control group.(2)The allele frequency and the genotype distribution of the five SNPs were significant differences between two groups. Minor allele carriers of the five SNPs were associated with increased risks of childhood obesity compared with the wild-type genotype. (3)After adjustment of age, sex and BMI-z score,all of the five SNPs showed a trend towards higher SBP. In addition, rs3751812 and rs8050136 showed significant as-sociation with LDL-C and HOMA-IR levels. Conclusion The five common SNPs in the FTO gene contributes to the e-tiology of obesity and hypertension. The FTO gene polymorphisms (rs3751812 and rs8050136)are found to be associ-ated with increased insulin resistance and plasma LDL levels.
