And the ability of antioxidant of polyhydroxy benzamides don't have too many differences with Trolox (IC50 =13.90 μg/ml), the substition of hydroxy group at amino benzene ring doesn't affect the whole ability of antioxidant apparently, but while the single hydroxy group at carboxylic acid benzene ring, they are apparently decrease to scavenge the ability of free radical, as a result, the hydroxy at amino benzene ring substitutes its function, without the hydroxy group, the ability of antioxidant is worst, but it upgrades its function while the hydroxy and amino are in the ortho-position or para-position.

而当多酚醯胺化合物其抗氧化能力与Trolox差不多时(IC50 =13.90 μg/ml)，胺基苯环上之羟基取代对整体抗氧化能力影响不明显，但在羧酸苯环上具单羟基时，其清除自由基能力明显下降，使得胺基苯环上羟基取代发挥了影响力，无羟基取代时，抗氧化能力最差，而羟基与胺基互为邻位或是对位时较间位有提升效果。

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。

When the researchers compared these patients' earlier brain scans with those of the other 11 prodromal patients, the only difference in activity was in the CA1 subfield--these seven patients had a 50% greater level of CA1 activity than the others did.

当研究者比较这7位病人和其他11位病人的早期脑扫描，脑活动上仅有的不同是在CA1子域--这7位病人有着高于其他病人50%的CA1子域活动。

In the paper, a generalized error model for the robots is set up by using DH coordinates. Moreover, a new analytical technique called"analysis on the error prominency factors for the robot pose error"is proposed. Numerically, the error prominency factor can express the extent of influence on the pose error of the end effector resulted form every DH parameter error within the whole working space of the robot.

在这一研究过程中，除了建立了用DH坐标描述的机器人末端位姿误差和轨迹误差的通用模型之外，还提出了一种新的机器人位姿误差分析技术——机器人位姿误差的显著性分析法。

During a median follow-up of 28.9 months, 39 (62%) of 63 suriing patients had one or more late complications: biliary stricture in 4 (6%), pseudocyst in 5 (8%), pancreatic fistula in 8 (13%), gastrointestinal fistula in 1 (2%), delayed collections in 3 (5%), and incisional hernia in 1 (2%); interention was required in 10 (16%) patients.

在接下来的平均28.9个月中，63位生存者中有39人（62%）发生一种或更多的远期并发症：胆道狭窄4人（6%），假囊肿形成5人（8%），胰瘘8人（13%），胃肠瘘1人（2%），延迟愈合3人（5%），切口疝1人（2%）；10人（16%）需要干预治疗。63位生存者中有16人（25%）的胰腺外分泌功能不全，58位无糖尿病史的病人中有19人（33%）的胰腺内分泌功能不全。

The X-ray crystal structure analysis of the complexes shows that all lanthanidecomplexes exhibit a tripodal ligand coordination mode, with three imino nitrogenfrom benzimidazolyl and pyridyl group, and one amino nitrogen atoms as donors.The ligands show two kinds of configuration: the fan-like and the pincer-like. Bothintra- and intermolecular π-π interactions are found in these complexes.

晶体结果表明，在所有的稀土配合物中，三脚架配体均用三个支脚上的苯并咪唑、吡啶环氮原子及一个顶端的氮原子和稀土离子进行配位，表现出三脚架式配位方式，同时，三脚架配体有风扇形及钳子形两种空间配位构型，并形成了分子内及分子间的π-π堆积作用。

The polycondensation of the benzoguanamine and pyromellitic Dianhydride was carried out under microwave irradiation, and the resulted polyamic acid was grafted with TDI-para position substitution aniline derivatives. Thus graft polymers with different electronic effect of the end group in side chain were obtained.

The statistic analysis of the relationship between the operative amounts and the corrected amount of eye primary position of 177 operations on the horizontal recti showed a positive proportional relation. And the correction effect in degree for each mm of surgery is between 1. 2°～2. 2°, and for different types of strabismus and different surgical treatments, the correction effects for each mm of surgery are different.

对临床177例眼水平直肌手术的手术量与眼位矫正量的关系进行了统计分析，结果表明水平直肌的手术量与眼位矫正量有较好的正相关关系，大约每毫米手术量对应的手术矫正量在〓之间，不同类型的斜视、不同的手术，每毫米手术量对眼位的矫正量不同。

Postoperative right-sided obstruction occurs more frequently after ASO repair of Taussig-Bing heart than after TGA arterial switching, leading to higher reintervention rate.
