Adipocytes in bone marrow cavity could decrease the activity of ALP, weaken the expression of Collagen Ⅰ mRNA, inhabit osteogenic potential of bone marrow stromal cell, and induce apoptosis of bone marrow stromal cells.

髓内脂肪细胞可降低骨髓基质细胞内ALP活性，减弱CollagenⅠ mRNA表达，干扰其成骨能力，并能诱导骨髓基质细胞发生凋亡，在骨质疏松症的发病中有着重要的意义。

在A组的每只兔子的一侧膝关节股骨滑车部人为造成3mm×4mm的骨软骨缺损，骨刀切除软骨下骨到髓腔渗血为止(厚约4mm)，压迫后FG止血；取髂骨骨块，并尽可能保留松质骨，取下的骨块用PBS反复清洗，以除去血细胞，将松质骨填充在骨缺损处，松质骨面朝向关节腔，高度与周边软骨下骨齐平，把骨膜片生发层朝向关节腔，用无创伤缝合线缝合在周边的软骨或滑膜组织上；向EP管中加入1/2悬液体积的FG主体胶溶液并混匀，再与主体胶等体积的催化剂溶液一同注射入骨膜与骨块密闭的腔隙中；同理处理另一侧膝关节。B组处理与A组相比只是不加入软骨细胞；C组造成骨软骨缺损，FG覆盖创面后单纯用骨膜修复缺损。

The median patient age was 41 years, 1 female and 3 male. The patients received BMSCs infusion at a dose of (1.0-2.0)×107 cells every time by intrabone marrow injection from the anterosuperior iliac spine and BMSCs from the same donor for the same patient were infused more than once.

骨髓间充质干细胞髓内注射具体方法：取右髂前上棘为穿刺注射点，注射骨髓间充质干细胞悬液，4例患者的给药剂量基本控制在(1.0~2.0)×107个细胞/次，行间断多次给药。

Several conclusions are drawn from the study. The ore deposit mainly occurs in the lower Cambrian Shuigoukou Formation, which is situated at the limbs of Qingshixia-Yujiatai overturned multiple syncline. The ore-hosted rocks are silicalite and mudstone. The content of SiO2 is high in the rocks of V ore deposit. Silicalites are mainly aphanitic quartz and chalcedony and the barite is sedimentogenic. The correlation between V and Cr, U, Ba is good. The rare earth element distribution patterns show Ce-negative or positive anomaly, obviously Eu positive anomaly and the right dip graphics.

研究结果表明，该区钒矿主要产出于青石峡－余家台倒转复式向斜两翼下寒武统水沟口组下岩段硅质岩夹泥岩的泥岩中，矿体产状与地层产状基本一致；钒矿床中所有岩石都含有较高的SiO2，硅质岩以隐晶质石英和玉髓为主，有沉积成因重晶石；V与Cr、U、Ba相关性好；稀土元素球粒陨石标准化模式具有或正或负的Ce异常和明显的Eu正异常、向右倾的图形。

According to petrographic facies test, gravel sample mainly consists of quartz, albite, dolomite, and minor biotite; and sand sample is mainly made up of quartz and albite. As an important ASR active mineral, chalcedonite exists in fractures of dolomite and in matrix of cherty limestone. In rapid mortar bar test, expansion of sand, small gravel and middle gravel at 14 day are less than 0.1%, but keep increasing in long term.

岩相法检测显示卵石样品主要由石英、钠长石及白云石和少量云母类矿物组成，砂样品主要由石英、钠长石等矿物组成，重要的碱活性物质玉髓主要出现在白云岩裂隙和硅质灰岩的基质中；&砂浆棒快速法&检测结果显示砂、小石、中石样品14天的膨胀率均不超过0.1％，为非碱－硅酸反应活性骨料，但卵石样品仍具有一定的碱活性，且后期膨胀率一直持续增长。

Following brain stem injury,the number of GFAP-positive astrocytes in cerebral cortex and pervent-ricular area,dorsomedial and ventro-medial pafts of midbrain at 30 min antemortem,and in periventricular area,dorsomedial part of pens,dorso-medial and ventro-medial part of medulla oblongata at 60 min antemortem.

采取针刺法造成实验大白鼠脑干损伤，用免疫组织化学LSAB法检测大脑、中脑、桥脑及延髓等不同部位脑组织中胶质原纤维酸性蛋白的改变。结果发现，生前损伤30min，大脑顶部灰质及中脑腹例中央部的GFAP阳性星形胶质细胞数目增多；生前损伤60min，除大脑顶部灰质及中脑腹侧中央部外。

BACKGROUND: Lipopexia induced by glucocorticoid is fat precipitation in marrow due to abnormal lipometabolism, or differentiation of cells resulting from hormone-affected bone marrow mesenchymal cells.

摘要背景：糖皮质激素引起的髓内脂肪蓄积是由机体脂肪代谢异常在髓内形成的脂肪沉淀，还是由于激素直接作用于骨髓间充质细胞使细胞发生了分化，以及具体生成的过程目前还没有定论。

BACKGROUND: Lipopexia induced by glucocorticoid is fat precipitation in marrow due to abnormal lipometabolism, or differentiation of cells resulting from hormone-affected bone marrow mesenchymal cells. The precise generating procedure remains unclear. OBJECTIVE: To investigate effects of various concentrations of dexamethasone on adipogenic differentiation of bone marrow mesenchymal cells.

Fig 1 At the experimental side, two weeks after operation (HE ×100) Many pieces of cartilage cells and spindle-shaped mesenchymal cells were found, by light microscope Fig 2 At the experimental side, twelve weeks after operation (HE ×100) Medullary cavity had formed, which contained hemoblasts and adipocytes, but the trabculae was not typical, by light microscope Fig 3 At the experimental side, twenty-four weeks after operation (HE ×100) The typical cancellous bone had formed, by light microscope Fig 4 At the control side, twenty-four weeks after operation (HE ×100) A large part of CXB was degraded, resorbed and replaced by fibrous tissue, but there was'not any new formed bone, by light mocroscope

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
