The results indicated that the typical apoptosis was induced by PRRSV in lungs and uteri. The ultrastructural changes showed different characterizations at different stages of the infection. During the early stage from 8th h to day 3 postinfection,the apoptosis cells shrank,the cytoplasm concentrated,the chromatin condensed,the kernel disaggregated and the endoplasmic reticulum dilated. During the middle stage from day 5 to day 9 postinfection,the apoptosis cells evidently shrank,the cell membranes protu berated,the plastosome manifolded,and apoptosis bodies were found. During the last stage from day 10 upwards postinfection,the apoptosis bodies degenerated and disappeared,and no inflammation occurred. Few apoptosis cells were necrotic.

结果表明，PRRSV可诱导宿主肺和子宫发生典型的细胞凋亡，表现为细胞的超微形态结构随着病毒感染进程出现不同的特征性变化，早期（感染后第8 h至第3 d）凋亡细胞多表现为细胞体积缩小，细胞质密度增强，染色质浓缩，核仁解体，内质网扩张；中期（感染后第5 d至第9 d）凋亡细胞体积显著缩小，细胞膜突起，线粒体增多，有凋亡小体形成；晚期（感染后第10 d以后）凋亡细胞形态多表现为凋亡小体降解和消失，少数凋亡细胞在凋亡晚期表现为坏死细胞。

In obese children, leptin concentration decreased during 4 mo of physical training and increased during a subsequent 4-mo period without physical training, fat mass was highly correlated with baseline leptin, and greater reductions in leptin during 4 mo of physical training were seen in children with higher pretraining leptin and in those whose total mass increased least.

在肥胖小孩中，4mol 周期体力运动使瘦素浓度降低，在接下来不运动的4-mo 周期中，瘦素水平提高。在那些体重增长最慢、运动前瘦素水平高的肥胖小孩中，4-mo 体力运动周期使其瘦素水平降低程度非常明显。第二篇翻译原文全文。pdf (43.99k)杂志，年，卷，期，页

This article studied differences in postpartum fatigue and birth outcomes between women who pushed immediately and those who delayed pushing during the second stage of labor. Data were collected from primiparous women in their 38th to 42nd gestational week who did not receive epidural analgesia during labor and were free of complications during pregnancy. Using a quasi-experimental design, 72 participants selected by convenient sampling were assigned based on individual participant's preference to either an experimental or control group. For the experimental group, pushing was delayed until the point after full cervical dilation at which the mother felt a strong physical pushing reflex, the fetal head had both descended to at least the +1 level in the pelvis and turned to the occiput anterior position, and uterine contractions were at least 30 mmHg. For the control group, the physician instructed mothers to begin pushing after full cervical dilation at the point when the fetal head was in the occiput anterior position and uterine contractions were at least 30 mmHg.

本研究目的在探讨初产妇女第二产程立即用力与延迟用力对产后疲惫及生产结果的影响，收案对象为怀孕38-42周初产妇女、待产期间未施打硬脊膜外麻醉，且怀孕期间无任何合并症，於待产期间向其解释研究目的及收案方法后予以收案，采类实验设计法，以方便取样并依个案之意愿分派於实验组及控制组，实验组於子宫颈完全扩张后等到强烈想用力的感觉、胎头位到达坐骨棘连线下1公分以下、胎头位置转到枕前位、子宫收缩规律强度至少30mmHg才教导向下用力；控制组於子宫颈完全扩张后即教导向下用力，共收案72位。

Relative to nitrogen topdressing in prophase, it mainly due to retroposition can provide nutrients for the wheat during flowering and grouting. Another way, it can help slow down the decline in leaf area and leaf chlorophyll content and photosynthetic rate during later stage, to meet the nutritional requirements during developmental stage of grains.

结合以往试验结论，本试验推断认为由于追氮时期后移既有利于开花和灌浆阶段养分的需要，同时有利于延缓小麦生长后期有效叶面积、叶绿素含量和光合速率的急剧下降，从一定程度上满足籽粒发育阶段的营养所需。

The results showed that glucose and fructose are primary soluble sugars from night to 10: 00 a.m. in mature leaves, but during 13: 00 - 16: 00 p.m., stachyose becomes the most abundant oligosaccharide, this diurnal change is mostly due to the tempestuous fluctuation of stachyose concentration in mature leaves. During photoassimilate transportation, the p rimary soluble sugar in phloem sap is stachyose. When transportation is finished, sucrose becomes the main sugar in phloem sap. Cucumber leavesmay store photoassimilate in the forms of starch, glucose, fructose, stachyose and sucrose at night. The concentrations of glucose, fructose and stachyose in phloem sap are much lower than in leaves at that time. There may be some unique mechanisms modulating source-sink translocation by which soluble sugars in leaveswere prevented from loading into the phloem further during night.

结果表明夜间至上午10： 00，葡萄糖和果糖是叶片中主要的可溶性糖，而下午13： 00至16： 00，水苏糖成为成熟叶片中含量最高的可溶性糖，这种变化主要由叶片中水苏糖含量剧烈的昼夜变化引起；当黄瓜同化物从源叶向外运输时，韧皮部汁液中的可溶性糖以水苏糖为主，运输完毕后则以蔗糖为主；黄瓜成熟叶片在夜间以淀粉、葡萄糖、果糖、水苏糖、蔗糖等各种形式贮藏尚未运出的同化物，而此时韧皮部汁液中葡萄糖、果糖、水苏糖的含量极低，可能有特定的源库调节机制阻止叶片中的可溶性糖在夜间进一步向韧皮部中装载。
