但是重力是如何发生的呢？

Finally, a lot of people with myasthenia gravis undergo surgical removal of the thymus.

最终，许多重力患者会进行胸腺切除术。

The good news is is that treatment has been able to reduce mortality from myasthenia gravis.

好消息是现在的治疗方案可降低重力的死亡率。

To better understand myasthenia gravis, let's review normal muscle contraction but at the cellular level.

为了更好的理解重力，细胞水平来了解一下肉正常收缩时的状态。

In very rare cases, myasthenia gravis can present as a paraneoplastic syndrome, which means that an underlying cancer like bronchogenic carcinoma or thymic neoplasm (also known as thymoma) generates an immune response which results in generation of autoantibodies.

在极罕见的情况下，重力会表现出副肿瘤综合征，这意味着潜在的癌如支气管肺癌、胸腺肿瘤导致免疫应答产生了自身抗体。
