A coronavirus was isolated from patients with SARS that might be the primary agent associated with this disease. Serological and molecular tests specific for the virus permitted a definitive laboratory diagnosis to be made and allowed further investigation to define whether other cofactors play a part in disease progression.

Limb RIPC attenuates intestinal and pulmonary injury in patients undergoing elective open infrarenal abdominal aortic aneurysm repair without any potential risk.

Limb RIPC attenuates acute lung injury via improving intraoperative pulmonary oxygenation in patients without severe pulmonary disease after lung resection under propofol-remifentanil anesthesia.

Background: Tai Chi is a systematic whole body movement developed in ancient China. It plays an increasingly important role in the field of pulmonary rehabilitation for patients with chronic obstructive pulmonary disease (COPD). Our review aimed to explore the impact of Tai Chi on the physical and mental health of patients with COPD. Methods: We searched several English and Chinese databases and used the combination of subject words and free words to search for available literature from the establishment of the library until August 28, 2018.Two researchers screened studies and collected the data independently. The study inclusion criteria included:(I) patients diagnosed with COPD; (II) Tai Chi or Tai Chi Qigong as an intervention in addition to routine treatment; (III) routine treatment with or without exercises as control group. The primary outcomes were lung function, exercise capacity and health status; (IV) randomized controlled trials. Results: Sixteen articles were included from 2009 to 2018 (n=1,096). The average time duration of Tai Chi program was 53.4 minutes each session, 4.13 sessions a week for a total of 4.13 months. Comparing with control group, Tai Chi group improved some lung function (forced volume capacity: mean difference =0.
