呼吸系统疾病诊治绝招
肺气肿系指终末细支气管远端（包括呼吸性细支气管、肺泡管、肺泡囊和肺泡）气腔增大，并伴有腔壁破坏性改变的一种病理状态。主要包括阻塞性肺气肿、老年性肺气肿、代偿性肺气肿及灶性肺气肿等。阻塞性肺气肿最为常见，它是由于慢性支气管炎或其他原因逐渐引起的细支气管狭窄，终末细支气管远端气腔过度充气，气腔壁膨胀、破裂而产生的肺脏充气过度和肺容积增大的阻塞性肺病。慢性支气管炎、多年反复发作的支气管哮喘、尘肺、广泛性支气管扩张和慢性纤维空洞性肺结核等，凡能引起细支气管炎性变化使气道阻塞，都可引起本病。多见于老年人。

Keith Stoner had been in a state of suspended animation for eighteen years. It was eighteen years earlier that Stoner had been an American member of a joint U.S. - Soviet venture to capture an alien ship, but when the Soviets had to pull out, Stoner willfully persisted and it was then, during that time on the strange ship that Stoner fell into the strange state that was neither here, nor there.Jo Camerata, the ambitious young student who fell in love with Stoner is now head of Vanguard Industries, which has recovered the alien ship. As a result, her company now controls the vast new technology and the fortune it reaps in - as well as control of Keith Stoner. What Camerata doesn't know, however, is that someone else has been awake, someone who dwells deep within the labyrinths of Stoner's mind.
