先兆

The main indication of respirator is severe hypoxemia uncorrected by fixed chest and foreboding of ARDS.

呼吸机的使用指征主要是胸壁固定不能纠正的严重低氧血症和ARDS先兆。

Its structure and property have not been understood clearly. Polyimide wear-out and breakdown can occur under long-term electric stressing due to many different reasons, making their insulating life ended. Wear-out and breakdown of polymers are closely related to the dissipation of electrostatic energy in space charge region.

聚合物的老化和击穿与空间电荷区域静电能的释放有关，电致发光代表材料中分子受激的化学活性强的状态，是能量耗散的方式之一，可作为材料预击穿及结构老化的先兆，是研究聚合物分子中的陷阱结构和它所控制的空间电荷的存贮和输运特性的重要实验手段。

This yellow fatty streak seen in childhood is not necessarily a precursor of adult atherosclerosis and occurs in populations in which atherosclerosis is uncommon; it is presumably reversible at this stage.

孩童时期便可见到的这种黄色脂纹，并不一定是成年后动脉粥样硬化的先兆，若发生在动脉粥样硬化病不常见的人群中，可能在此阶段是可逆转的病变。

The fast NAT acetylator status, which may result in altered NAT detoxifaction capacity, is associated with preeclampsia.

NAT快乙酰化状态，可能改变NAT的解毒能力，与先兆子痫相关。

Study design: The NAT acetylator status was determined by measuring urinary caffeine metabolites in 134 nonpregnant women with a history of preeclampsia and in 109 control women with uncomplicated pregnancy.

研究设计：通过检测尿咖啡因代谢产物测定NAT的乙酰化状态，检测有先兆子痫史的134例非妊娠妇女和109例无并发症的妊娠对照妇女。

Results All cases became amenorrheic during GnRH-α therapy. The enlarged uteri all decreased to normal or near normal size. Menstruation returned in 80～90 days after cessation of treatment. Three cases conceived within four menstrual periods. One of them resulted in the birth of a healthy 3 150 g male at 38 weeks gestation by cesarean section. The second pregnancy resulting after adenomyomectomy was terminated by emergent cesarean section at 30 weeks gestation because of threatened rupture of uterus. The third is now normal at 28 weeks pregnancy .The fourth has had 2 menstrual periods and is still being followed up.

结果 GnRH-α用药期间4例均闭经，血雌二醇于用药的第3周降到绝经期水平；用药6次后增大的子宫缩小至正常或接近正常。1例子宫后壁局限性腺肌瘤未行手术切除者，用药后腺肌瘤缩小73.7%。3例于腹腔镜术后、停药转经的4个月内妊娠；另1例停药转经2个月，现在随访中。3例妊娠转归：1例足月剖宫产分娩；1例手术切除肌壁间腺肌瘤者，孕30周时因先兆子宫破裂急诊行剖宫产术；1例目前孕22周。

Hypertension, preeclampsia, bacterial and viral infection resulted from immuno-suppression therapy and increasing rate of caesarian section are the major risks for the mother.

高血压、肾功能损害、先兆子痫、继发于免疫抑制的细菌和病毒感染以及剖宫产几率增加是母体的主要风险。

Three other works—Prognostic, Coan Prognosis, and Aphorisms—advanced the then-revolutionary idea that, by observing enough cases, a physician can predict the course of a disease.

另外三篇著作--先兆、预后、谚言--相比后来提出的通过充分的病情观察，医生能预知疾病发展过程的观点，提出的还要早。

Through upregulating the production of MMPs in deciduas and chorionic villi, the upregulation of the expression of EMMPRIN in syncytiotrophoblast and cytotrophoblast column of the villi in the threatened abortion can degenerate deciduas and denudates embryo.

发生先兆流产时合体滋养细胞、细胞滋养层柱所表达的EMMPRIN增强可能通过上调绒毛及蜕膜组织中基质金属蛋白酶的水平，降解细胞外基质，使绒毛剥离、蜕膜组织剥脱。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
