搏动

Cardiac explants grew well in the collagen gel. Adjacent explants were connected to each other by the migrating cells with the occurrence of autorhythmic beating of the explants.

在三维胶原中，心脏组织块生长良好，迁出的细胞将相邻组织块连接起来，组织块有自发的搏动。

I have eight weeks of pregnancy, B-Uterus anterior, palace wall echo uniform, intrauterine pregnancy 45 24mm see echoes, see inside a human fetus in its echo, brachiocephalic length 20mm, see heart throb.

我怀孕有8周了，B超子宫前位，宫壁回声均匀，宫腔内见45 24mm妊娠回声，其内见一初具人形胎儿回声，头臂长约20mm，见胎心搏动。

In pursuit of pulsatilerelease, various design strategies have been proposed, chiefly including reservoir, capsular and osmotic formulations.

在追求搏动释放，各种设计策略已提出，主要包括水库，包膜和渗透配方。

The single ventricle and the midgut hermia appered in the early stage at the top of the middle cerebromedullary tube were temporary structure. With the development of the fetus these structures would disappear gradually. The impulse rate of primordium heart was 100 to 193 per minute.

胚胎早期中枢神经管头端出现的单脑脑泡和消化系统的中肠疝是过渡性的结构，随着妊娠的发展，这些结构逐渐演变和消退，原始心管搏动范围在100~193次／min。

The cardiomyocyte viability were detected by MTT assay for calculating the survival rate and the inhibitory rate of the virus. Myocardial F-actin and VEGF were analyzed by immunofluorescent staining with confocal microscopy. Mean fluorescent intensity of F-actin and VEGF were determined by flow cytometry.Results There is no toxicity on cardiomyocytes when PD is at concentration of 0.02 mmol/L and 0.2 mmol/L while there is toxicity at concentration of 2 mmol/L. CVB3 could reduce the viability of cardiomyocytes, depolymerize F-actin cytoskeleton and reorganize VEGF protein.

体外培养心肌细胞，用100 TCID50柯萨奇B3病毒（CVB3）感染心肌细胞，建立病毒性心肌炎实验模型，然后分别用0.02mmol/L、0.2mmol/L、2mmol/L三种不同浓度的PD处理感染CVB3病毒的心肌细胞，观察心肌细胞的形态和搏动，用细胞免疫荧光技术标记纤维状肌动蛋白和VEGF蛋白，四唑蓝比色法测定心肌细胞活性和病毒抑制率，流式细胞仪检测各组心肌细胞VEGF蛋白和F-actin平均荧光强度。

Essential hypertension caused by neurovascular compression of the left ventrolateral medulla was associated with malbalance of vasomotor center in the dorsal medulla. The possible pathogenesis was the following:① An irritation of the left RVLM by pulsatile compression of an ectatic vessel would increase activity of central sympathetic neuron.② Neurovascular compression at the REZ of the cranial nerves Ⅸ and Ⅹ decreased excitation of parasympathetic nerve.③ Decreased sensitivity of afferent inputs to neuron of nucleus tractus solitarii in the sensory area lead to hyperactivity of central sympathetic nervous system due to pulsatile compression of the left RVLM.④ Neurocompression of the left RVLM and REZ in the left cranial nerves Ⅸ and Ⅹ lead to an overactivity of central renin angiotensin system.

3，结论：左侧延髓腹外侧Ⅸ、Ⅹ颅神经REZ动脉血管压迫所导致的高血压的发生与左侧延髓血管运动中枢对血压的调节失衡有关，其可能机制是：①左侧RVLM在搏动性血管压迫刺激下，中枢交感神经元活性增高；②左侧Ⅸ、Ⅹ颅神经REZ受压导致副交感神经兴奋性降低；③感受区孤束核神经元接受迷走神经传入冲动的敏感性减低，导致中枢交感神经活性增高；④左侧RVLM及Ⅸ、Ⅹ颅神经REZ受压引起中枢RAS活性增加。

Methods In total 148pregnant women were enro lled in this study. The e-chogenic feature and the blood flow i ndexesof the ovarian corpus luteum were ass essed from4th to 12th gestational week with tra ns-vaginal color Doppler ultrasono graphy.

方法采用经阴道超声检测148例早期妊娠4～12周孕妇的卵巢，观察卵巢内黄体的二维声像及彩色多普勒血流改变，检测收缩期最大峰值流速、阻力指数及搏动指数。

The sites headache were lateral or bilateral frontotemporal and parietal, features of pain were blunt and pulsative,last for 15～30 minutes. All the patients had abnormal TCD, 11 cases had increased asymmetric cranial blood flow, 4 cases had decreased brain blood flow.

头痛主要为单侧或双侧额颞、头顶部钝痛或搏动性痛，持续15～30 min.15例患儿TCD检测全部有异常，11例颅内血管呈不对称性血流速度增快，4例血流速度减慢。

Objective We measured resistance index and pulsatility index of interlobar artery to detect the relationship of changes of allograft function with changes of interlobar artery RI and PI in renal transplantation recipients.

目的 运用彩色多普勒超声测量移植肾叶间动脉的阻力指数和搏动指数，观察两者的变化情况与肾功能变化的关系。

Methods RI and PI of main renal artery and interlobar artery were obtained by color Doppler ultrasonography within the first week of transplantation.Then they were correlated with allograft glumerular filtration rate at 1 year.

在100例无并发症肾移植患者中，应用彩色多普勒超声，于肾移植术后1周内，测量移植肾肾动脉和叶间动脉的阻力指数和搏动指数，并与术后1年的移植肾肾小球滤过率进行相关分析。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
