1·Late in the pregnancy, the fetus pushes up against the thoracic cage and decreases a woman's lung capacity, putting her at risk for respiratory complications if she contracts flu.

在怀孕后期，胎儿推挤胸廓，导致孕妇肺活量减少，这样当她感染流感后，就面临着呼吸并发症的风险。

2·The falling function of the respiratory centre, the elastic resistance of the lungs and thoracic cage, and the non-elastic resistance in the respiratory tract are responsible for the decline.

其机制主要是呼吸中枢的功能降低，肺和胸廓的弹性阻力、呼吸道的非弹性阻力增加所致。

3·Objective: To evaluate the clinical value of reconstructive technique with titanium mesh cage for the treatment of thoracic and lumbar tuberculosis.

目的：探讨应用钛网前路重建技术治疗胸腰椎结核的临床价值。
