Natural L-astaxanthin is supercritical fluid extraction from haematococcus pluvialis powder.

天然左旋虾青素是雨生红球藻粉经超临界萃取，它是一种超强的天然抗氧化剂。

The astaxanthin-producing microalgae Haematococcus pluvialis is a fresh water unicellular greeen alga with complicated cell cycle.

雨生红球藻是一种能够合成强抗氧化剂-虾青素的单细胞绿藻，然而由于其生长速率缓慢，制约了虾青素产量的提高。

The unicellular green alga Haematococcus pluvialis accumulates the astaxanthin,with levels reaching up to 4%dry weight under environmental stress.

雨生红球藻是一种单细胞绿藻，在多种逆境胁迫条件下能够大量合成并迅速积累虾青素，其积累量最高可达细胞干重的4%，从而成为目前最理想的天然虾青素合成工具。

Glycerine postbulbar injected to block the ophthalmic ganglia in the absolute glaucoma patients is safe, easily operated, and conveniently adopted.

结论球后注射甘油进行睫状神经节阻滞是一种安全、操作简单、取材方便，患者无痛苦、易接受，可作为有症状绝对期青光眼的首选治疗方法。

Diethanol amine and 2,2-bis(methylene-2-bromoisobutyrate) propionyl chloride were used as divergent reagents respectively before preparations of the second and the third generations. The resultant polymers were characterized by GPC and ~1H NMR.

为了利用含有可降解链段的树枝状聚合物(dendrimer-like polymer)制备纳米空心球，我们结合ATRP和开环反应合成了两种苯乙烯和L-丙交酯的三代树枝状共聚物CPSt(PLLA_2_2_3和CPSt(PLLA_2_2_4。

Championship Manager 2007 is out now!

Championship Manager 2007》新加入了一种&比赛分析工具&，这种工具能够分析每一个球员和每一场比赛的各项统计数据，比如进球、奔跑、射门、过人、铲球的成功率和失败率等等，这些数据可以帮助玩家更为细致地了解比赛，让玩家成为顶级的足球经理。

H2 has the tendency of accelerating synthesis. And the mechanism is that H2 can not only accelerate the refinedness of the powder particle of Ti, make the novel surface of fracture clean, but also enhance the activation of Titanium.

结果表明，在5种不同球磨环境下用Ti粉和活性炭粉都能合成TiC，其中在H2环境下的合成速度最快。H2对TiC的机械合金化合成具有加速作用，其机理是H2不仅能促使Ti与活性炭粉末细化，使断裂的新鲜表面保持清洁，而且能使Ti的活性增强。

①Rat MSC and VSMC were cultured and identified, respectively. MSC were labeled with DAPI firstly, and then co-cultivated with VSMC. The changes of morphology and ultrastructure of co-cultured cells were observed. Immunfluorescence analysis was performed by using monoclonal antibodies against specific antigen.②We established the regulatable system in two steps: a stable MSC line expressing rtTA has been constructed and characterized firstly by transfected with pUHD 17-1hyg and then selected by hygromycin B; in a second step, this line was used for trandfer the AT2R gene to MSC to get the well establishing double stable MSC lines;③The expression of AT2R regulated by doxycycline was evaluated by western blot;④The MSCs were transduced into rat carotid arteries with regulatable AT2R gene after the establishment of rat carotid balloon injury restenosis model. The intimal/medial area ratio were measured by digital analysis system.

研究方法：(1)密度梯度离心法及胶原酶消化法分别培养原代大鼠MSC及VSMC，细胞共培养并行免疫荧光化学染色和透射电镜观察超微结构；(2)组成受Dox调控的哺乳动物表达系统的四种成分的转化、扩增及提纯并酶切鉴定；(3)采用常规分子生物学方法连续两个回合转染体外培养的MSC，并分别采用发光计检测不同细胞克隆萤光素酶活性改变以及RT-PCR方法检测AT2R目的基因mRNA表达情况，根据各个细胞克隆受Dox调控表达的程度，选择低背景、高诱导表达AT2R的细胞系，作为双重稳定MSC细胞系；蛋白免疫印迹法观察该细胞系在Dox调控下AT2R表达的时相性、持续性及在不同浓度Dox调控下的表达情况；(4)建立大鼠颈动脉球囊损伤动物模型，将双重稳定MSC在术中导入血管，分别于14 d、28 d进行病理切片，检测可调控AT2R对新生内膜增生的影响；采用RT-PCR免疫组织化学免疫荧光等技术观察AT2R基因在新生内膜中的表达以及细胞外基质成分表达的改变，TUNEL法检测血管组织中细胞凋亡的变化情况。

In this thesis, using a low molecular weight polymer TPA-PPV and a high molecular weight polymer PVK as the model compounds, a series of highly monodisperse nanoparticles with controlled size and shape had been prepared by reprecipitation method and a new method respectively.

本论文以小分子量聚合物TPA-PPV和大分子量聚合物PVK为目标化合物，分别用再沉淀方法和一种新的方法成功制备了一系列不同尺寸的、高度单分散的聚合物纳米超微粒，并研究了PVK纳米球二维阵列的自组装过程。

Although retrobulbar anesthesia is a relative safe method, but we can not forget those complications it may cause.

故提醒大家，球后麻醉注射虽然是一种相对安全的麻醉法，但我们仍不能忽略其潜在的一些并发症！
