卧床

Staying bed may go against the grain but that's what you must do if you want to get better.

也许你不愿意卧床，但是你要想病情好转，你必须卧床。

Compared with pre-HDT, the MA of calf decreased significantly (P.05) in the HDT 1st and 22nd day in control group; the MA of calf decreased significantly (P.05) in the HDT 7th, 22nd 26th, 30th day in limb muscular group; the MA of calf decreased significantly (P.05) in the HDT 7th, 10th, 22nd and 30th day in bicycle ergometric group.

与卧床前相比，对照组肌电振幅在第1和22 d显著降低(P.05)，下肢肌力训练组的肌电振幅在卧床第7、22、26和30 d显著降低(P.05)，自行车功量计组在卧床第7、10、22和30 d显著降低(P.05)。

In control group, pulsatility index and peak systolic flow velocity/ end systolic flow velocity decreased significantly (P.05) in the HDT 14th, 26th and 30th day, resistance index decreased significantly (P.05) in the HDT 26th and 30th day; in the limb muscular group, PI, RI and S/D decreased significantly (P.05) in the HDT 26th day; in the bicycle ergometric group, PI, RI and S/D decreased significantly (P.05) in the HDT 3th, 22th and 30th day.

对照组的脑血管阻力指标PI、S/D在卧床第14、26和30 d，RI在卧床第26和30 d较卧床前显著降低(P.05)；下肢肌力训练组的PI、RI、S/D在卧床第26 d显著降低(P.05)；自行车功量计训练组的PI、RI、S/D在卧床第3、22和30 d较卧床前显著降低(P.05)。

The results showed that the perimeter of leg significantly decreased (P.05), further decreased (P.01) in a HDT time-dependent manner compared with pre-HDT; in limb muscular group, the perimeter of leg decreased significantly (P.01) during from the HDT 18th day to the 30th day compared with pre-HDT; in bicycle ergometric group, the perimeter of leg decreased significantly (P.01) during from the HDT 22nd day to the 30th day ; in the HDT 10th day, the perimeter of leg in bicycle ergometric group increased significantly (P.05) as compared to that of control group; in the HDT 18th day, the perimeter of leg in limb muscular and bicycle ergometric group increased significantly (P.05) compared with control group.

结果发现，与卧床前相比，对照组小腿围径在卧床第1d显著减小(P.05)，随卧床时间延长进一步显著减小(P.01)；下肢肌力训练组在卧床后期(18～30 d)以及起床后的小腿围径显著减小(P.01)；自行车功量计训练组在卧床第22～30 d及起床后显著减小(P.01)；卧床第10 d自行车功量计训练组的小腿围径显著大于对照组(P.05)，第18 d下肢肌力训练组和自行车功量计训练组的小腿围径均显著大于对照组(P.05)。

Changes of lipid hyperoxidation and amount of circulating endothelial cells under simulated weightlessness and factors that may influence these changes were observed in 3 groups of subjects (5 in each group) exposed to 17d -6° head down bed rest, HDBR+hypoxia and HDBR+qigong respectively.

为研究模拟失重、低氧、气功及其复合作用对人体脂质过氧化及循环内皮细胞含量的影响，受试者为15名19～21岁男性健康青年，分为单纯卧床组、卧床＋低氧组和卧床＋气功组进行了17d的头低位－6°卧床实验。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
