[A survey of ankle-brachial index among natural population in Shanghai and Inner Mongolia Autonomous Region].
To investigate epidemiological characteristics and differences in ankle-brachial index (ABI) among the natural population in Shanghai and Inner Mongolia, and to observe the prevalence of lower extremity peripheral arterial disease (PAD). ⋯ The ABI value in Shanghai is higher than that in Inner Mongolia and the prevalence of lower extremity PAD in both males and females in Shanghai is significantly higher than that in Inner Mongolia. But they are lower than the level of western countries. In different age groups, the difference of the prevalence of lower extremity PAD between Shanghai and Inner Mongolia is only displayed in the age group of < 50 years, which may be related to the limited sample size. The natural population in Shanghai exposed artery atherosclerotic disease risk factors may increase and we need to pay more attention to the lower extremity PAD.

Meta Analysis Comparative Study[The effects and safety of closed versus open tracheal suction system: a meta analysis].
To evaluate the effects and safety of closed tracheal suction system(CTSS) versus open tracheal suction system (OTSS) for mechanically ventilated patients. ⋯ Compared with OTSS, CTSS could reduce disturbance to respiratory and circulatory system by sputum suction and shorten the duration of mechanical ventilation. However, CTSS has no advantage in prevention of ventilator associated pneumonia or microbial colonization, nor does it shorten the length of ICU stay or improve the outcome of mechanically ventilated patients.
