New achievements in the study

High intensity interval training and continuous training: pulmonary rehabilitation effects may be similar sport endurance exercise is effective component of pulmonary rehabilitation can improve exercise capacity in patients with COPD, improving the quality of life. Varge, comparison has high strength training, and intermittent training and self-pace training three species way of effect, will 71 cases in the heavy of COPD patients is divided into c, and I, and s three group, respectively accept high strength continuity training (45 min stepping car movement, and 80% peak work rate, and 3 times/week), and intermittent training (30 min stepping car movement, and 90% maximum power 2 min following the to 50% maximum power 1 min, and 3 times/  Weeks) and family-based self pace no supervisory training (45 min walking or climbing stairs). Group c and group ⅰ in patients with increased test for maximum power and maximum oxygen uptake rates were significantly higher, lactic acidosis markedly improved, and the two are not significantly different.  Activities of the Group of patients with questionnaire scores are improving and no significant difference between groups.  Skim material loss associated with poor prognosis and quality of life in patients with COPD catabolism secondary to systemic inflammation enhanced, thus leading to skim material (FFM) reduction.  Bolton, an 8-week study included 40 patients with stable COPD patients (GOLD  ~ ⅳ-class ⅱ), study of start, end, and after 4 weeks collecting, pseudouridine excretion in patients with pulmonary function and inflammatory markers, and other data. Results show that no matter how COPD, cells increased protein decomposition and FFM and skeletal muscle function and exercise endurance negative correlation.  Pulmonary rehabilitation can improve muscle function and exercise endurance, improve short-term FFM loss, but does nothing to reduce the cellular protein decomposition or systemic inflammatory markers. 6 MWD were good predictors of mortality of COPD patients of cardiopulmonary exercise test (CPET) result is good predictors of mortality of COPD patients, better than second forced expiratory (FEV1) life and health quality indicators.  365 cases of patients with stable COPD accepts CEPT and complete 6 min walking distance (6 MWD) testing, follow-up of 3-121 months. Findings average lifetime for patients (43 ± 24) month, most died from breathing failure. Mortality and 6 MWD, maximum oxygen consumption (VO2), maximum load, body mass index, FEV1, MMRC Borg scale measures such as clear relevance. Compare with Max VO2, 6 MWD is a better predictor of death.  5-year survival rate in patients with 6 MWD<350 m 39%,≪250 m only 26%. Respiratory HeO2 more than pure oxygen helps improve exercise tolerance in patients with hypoxemia whether or not they merge, oxygen therapy may improve symptoms in patients with COPD.  Under laboratory conditions, breathing helium-oxygen mixture (HeO2) as compared with separate oxygen can better improve exercise tolerance in patients with. Marciniuk on 16 cases of patients with COPD and obviously excessive air conducted a randomized, double blind study on transverse. In patients with baseline pulmonary function, CPET, 6 MWD tests first, then respectively in the three types of gas (indoor air or pure oxygen, HeO2 70%/30%)   under the condition of two follow-up, testing 6 MWD. Results show that compared with breathing indoor air and pure oxygen, respiratory HeO2, the increase in walking distance, and shortness of breath and lower extremity weakness has not increased.
