Itamin D from the skin and diet is metabolized in the lier to 25-hydroxyitamin D (Figure 1), which is used to determine a patient's itamin D status1,2,3,4; 25-hydroxyitamin D is metabolized in the kidneys by the enzyme 25-hydroxyitamin D-1-hydroxylase (CYP27B1) to its actie form, 1,25-dihydroxyitamin D.1,2,3,4 The renal production of 1,25-dihydroxyitamin D is tightly regulated by plasma parathyroid hormone leels and serum calcium and phosphorus leels.1,2,3,4 Fibroblast growth factor 23, secreted from the bone, causes the sodium–phosphate cotransporter to be internalized by the cells of the kidney and small intestine and also suppresses 1,25-dihydroxyitamin D synthesis.5 The efficiency of the absorption of renal calcium and of intestinal calcium and phosphorus is increased in the presence of 1,25-dihydroxyitamin D (Figure 1).2,3,6 It also induces the expression of the enzyme 25-hydroxyitamin D-24-hydroxylase (CYP24), which catabolizes both 25-hydroxyitamin D and 1,25-dihydroxyitamin D into biologically inactie, water-soluble calcitroic acid.2,3,4

从皮肤和食物来的维生素D在肝中代谢为25-羟基维生素D（图1），被用来决定病人体内维生素D情况的1，2，3，4；25-羟基维生素D在肾中被25-羟基维生素D1羟化酶（CYP27B1）转变为有活性的1，25-二羟基维生素D 。1，2，3，4由肾产生1，25-二羟基维生素D是被血浆甲状旁腺激素和血清钙，磷水平紧密调节。1，2，3，4由骨分泌的成纤维细胞生长因子23使钠磷协同转运蛋白被肾和小肠细胞内化及抑制1，25-二羟维生素D合成。5 在1，25-二羟基维生素D作用下肾和小肠吸收钙及磷的效率增高(图1)。2，3，6 它也包括25-羟四- 24 -羟化酶的表达(CYP24)，且将1，25二羟基维生素D和25羟基维生素D异化成无生物活性，水溶性的维生素D3-23羧酸。2，3，4

The Results shewed that there is the highest absorbance at 492 nm,and the standard recovery rates high,and the relative error small,and the recurrences good,and this method is simple and suitable for all kinds of defatted coffee grounds.

结果表明：它在492 nm 处有最大吸收峰，测定标准回收率高，相对误差小，重现性好。该法操作简单，效果良好，适用于测定各种类型脱脂咖啡渣中甘露聚糖的含量。

The tuberculous encysted dropsy with pleura conglutination in 8 cases,whose pleural encysted cavity was given puncture with thoracic puncture needle for injecting urokinase 100,00 units every time after extracting hydrothorax,was distinctly eased after being given anti-tuberculous treatment.The hydrothorax in 4 cases,whose recurrent hydrothorax was given pleura congluatination operation,did not occur.

平均3~5天胸水基本吸收后拔管。8例结核包裹性胸腔积液伴胸膜明显增厚患者予胸穿针每次抽液后注入尿激酶10万U，并予抗结核及支持对症治疗，胸膜粘连明显减轻。4例胸水反复出现，予胸膜粘连术后胸水不再产生。

Besides various interferences, the wave front diffusion, the ground absorption and the attenuation are all the causes of a weak seismic reflection and, plus the complicated superficial geologic setting and the reservoir bed features of low amplitude, low porosity and low permeability of the compacted thin detrital rock in HJQ, the conventional seismic amplitude fidelities do not meet the criteria of the seismic inversion.

除各种干扰外，地震波传播过程中的波前扩散、大地吸收、衰减等使地震反射能量变弱，加之杭锦旗地区复杂的表层地质条件和低幅、低孔、低渗致密性薄层碎屑岩的储层特点，使常规保幅地震资料离地震反演的要求还有差距，并且反演技术本身不具备噪音识别功能，包含噪音的反演必然会影响地质效果。

Compared with group C, the inflammatory infiltrates and bone resorption were more serious.

但S组与C组相比，炎症性浸润较重，并且S组根分叉区牙槽骨的吸收显著高于C组。

Well, if you have a laser busily reading the disc, there's obviously going to be quite a bit of reflection and scattering of the signal, and if it's reflected off anything back in phase with the signal that's going on it just mucks the signal up.

嗯，如果雷射头忙著读取光碟，很明显讯号就会有很多反射跟散射，而如果反射讯号又折回跟传输中讯号同相位那讯号就会被搞乱E所以光亮及具反射性的表面很容易破坏整件事，所以必须以能吸收红外线的漆来尽量控制这种情况

In the pot experiment of Cd and Zn uptake and portioning in organs in maturity with Red earth derived paddy soil was analysed.Cd was spiked at 0 and 2.5 mg·kg~(-1) of soil,respectively.

以大田筛选的籽粒镉积累水平不同的两品种(J196，低积累型，品种C；中浙优1号，高积累型，品种A)为材料，采用添加Cd2.5 mg·kg~(-1和不添加Cd处理在红壤性水稻土进行盆栽试验研究了杂交水稻在成熟期对土壤中Cd、Zn的吸收分配及籽粒Cd、Zn积累特点。

The actions in Peking Opera are inspired from life. Artists recomposed and enriched the actions to make them more beautiful and coherent.

京剧这些表演程式来自生活的灵感，艺术家吸收过来丰富表演程式，使它们更加美丽和具有连贯性。

They suggest that negatie remodeling could be resoled by slower stent absorption, and that "the excessie healing response could be limited by the controlled release from the stent of an antiproliferatie drug."

他们建议可以通过减慢支架的吸收速度来解决负性重塑，如果支架内有控释的抗增生药物就可以限制过度的修复反应。

Moreover, because the sites of bone mass gained in growth period by exercise and resorbed in aging years are different, the bone gained by exercise will be maintaining until old years.

而且由于生长期运动所增加骨量的部位和增龄性骨吸收的部位是不同的，因此认为生长期进行运动所获得骨量的增加可以维持至老年期。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
