钙化

Rickets is a ''failure of the bony matrix to mineralize,'' Baker said.

佝偻病是一种"骨基质钙化不足"性疾病，患此病时，骨骼变得软弱，典型佝偻病患儿的腿骨向外弯曲，导致骨骼畸形，严重病例甚至发生抽搐。

However, at least 1 outside observer urged caution in interpreting these findings."The reliability and validity of high-resolution computerized tomography in kidney failure has been questioned," Ell Friedman, MD, nephrologist and Distinguished Teaching Professor of Medicine at the State University of New York Downstate Medical Center in Brooklyn, told Medscape Nephrology . He cited a recent study by Barraclough et al ( Nephrol Dial Transplant . Published online before print May 1, 2008) showing significant imprecision in HRCT-derived validation of coronary calcification in kidney failure patients, depending on who reads the results.

然而，至少一位以上的外部观察者表示在阐释这些研究发现时必须特别小心，布鲁克林纽约州立大学Downstate医学中心的肾脏学家与卓越教学医学教授Ell Friedman医师向Medscape肾脏学表示，高解析度电脑断层扫描应用於肾脏衰竭上的信度与效度已经受到质疑；他引用最近一项由Barraclough等人（发表於Nephrol Dial Transplant，於2008年5月1日线上发表）的研究结果，显示HRCT延伸的肾脏衰竭病患冠状动脉钙化检验有相当程度的误差，取决於谁判读检验结果。

objective:to explore the clinical value of digital mammography on diagnosis of small breast cancer.methods:we retrospectively analyzed the representation of molybdenum target x-ray in 40 patients with small breast cancer diagnosed by biopsy.result:the molybdenum target x-ray showed nodosity tumor in 17 cases,calcification in 13 cases,density in 8 cases,focal grand architectural distortion in 6 case,single dilated in 3 cases and blood vessel line thickening in 6 case.conclusions:digital mammography is the most important means in the diagnosis of small breast cancer,which can distinguish between different kinds of breast density of different tissues and find small breast lump.the mammography has a high sensitivity in the diagnosis of small breast cancer.

目的：提高对小乳癌影像学的认识。方法：回顾性分析40例经病理证实的小乳癌患者的x线片。结果：x线表现为肿块17例，钙化13例，致密影8例，局部结构紊乱6例，单支导管扩张3例，血管影增多、增粗6例。结论：影像学是小乳癌诊断的最主要手段，能区别乳房各种不同组织的不同密度，能发现较小的乳腺肿块，对于乳腺癌的诊断，乳腺x线钼靶摄片具有较高的灵敏度。

He type of ossein in group B was mainly type Ⅰ collagen while that in group A type Ⅱ and it exhibited as a process of fiber formation in group C. The reason for why TGF-β〓 can promote ossification induced by BMP is that can promote the differentiation and proliferation of mesenchymal cells to supply more target cells for BMP, promote the differentiation and proliferation of mature osteocytes and chondrocytes, inhibit metalloproteinase to decrease the destruction of bone tissue and promote calcification of bone matrix.

GF-〓能促进BMP骨诱导作用主要因其能促进间充质细胞的分裂增殖为BMP提供丰富的靶细胞、促进成熟骨及软骨细胞的分裂增殖、促进骨细胞产生Ⅰ型胶原而抑制软骨细胞产生Ⅱ型胶原，抑制金属蛋白酶的活性以减少组织破坏、促进基质钙化等作用而使骨生成能力增加，提示它和BMP具有协同作用。

Children often swim, it will promote bone calcification, can effectively prevent the occurrence of rickets and osteomalacia.

儿童常常游泳，则会促使骨骼钙化，能有效地防止佝偻病和软骨病的发生。

Because it is rich in vitamin A and vitamin D, so put it as unsolicited medical supplies and health supplies, prevention and treatment of night blindness, rickets pharmaceutical effects, but also the promotion of effective drugs for tuberculosis empty calcification can also be used for vitamin A deficiency of dry eye syndrome and vitamin D deficiency osteomalacia.

由于它富含维生素A和维生素D，因此自来就把它作为医药用品和保健用品，是防治夜盲症、佝偻症的特效药剂，也是促进肺结核空洞钙化的有效药物，也可用于维生素A缺乏症的干眼症和维生素D缺乏症的软骨症。

Results Metaphysis osteoporosis was observed on X-ray and CT in acute stage, the midsection of infarct of bone was isointensity on T1WI and iso/hyperintensity signal on T2WI, the edge of infarct of bone was ring-shaped hypointensity on T1WI and hyperintensity signal on T2WI. Small worm-eaten change and stippled calcification was observed on X-ray and CT in subacute stage, the infarct of bone was iso/hypointensity on T1WI and iso/hyperintensity signal on T2WI, the edge of infarct of bone was ring-shaped hypointensity on T1WI and hyperintensity signal on T2WI. Irregular and wriggle osteosclerosis was observed on X-ray and CT in chronic stage, was hypointensity on T1WI and T2WI.

结果 骨梗死急性期X线、CT表现为干骺端骨质疏松，MR T1WI骨梗死灶中央部分呈等至高信号，T2WI呈高信号，T1WI骨梗死灶边缘呈环形低信号，T2WI呈环形高信号；亚急性期X线、CT表现为小的虫噬样改变，伴有斑点状钙化，MR T1WI骨梗死灶呈等或低信号，T2WI呈等或稍高信号，T1WI骨梗死灶边缘呈环形低信号，T2WI呈环形高信号；慢性期X线、CT表现为不规则状、蜿蜒状骨质硬化，MR T1WI和T2WI均呈低信号。

The tumors diameter varied 2~12 cm, the upper outer quadrant was the most commonly involved site. All tumors were high uniformity density, no calcifications, their shape including oval and-Shaped, and surface depressed in 2 enormous mass.

肿块直径2~12 cm，外上象限多见，形态分别为椭圆形、分叶形，边界均较清晰，巨大肿块2例表面凹陷；9例均呈实质性均匀密度，无钙化；5例边界有透明晕环绕，腋窝均未见肿大淋巴结。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.
