In the late stage, every layer of keratoconus had pathological changes.

圆锥角膜组织在病变的晚期各层均有病理变化，铁质在角膜上皮层和前弹力膜的聚集，基质层酸性粘多糖的减少，均与圆锥角膜的病理变化有密切的关系。

The characters of geochemistry are rich alkali. And at the same time the content of calcium is high. They are rich in alkali, high in Potassium, enriched in LILE, LREE and Pb, depleted in HFSE and have a small Sr, Nd, Pb isotope range. Their source is probably a kind of even metasomatic mantle. This is consistent with the fact that there is kimberlite containing flogopite in the deep-source enclosure of Cenozoic super-K alkali lava in the southern part of this rock zone.

Results:In experimental group,all 20 rats have unifocal masses and S-100 protein without extracerebral metabasis and the extracranial extension. The size, the site and morphology of all tumors are almost the same.

结果：脑胶质瘤组，20只大鼠经MRI平扫、增强扫描和形态学检查证实均有单灶肿块，且肿瘤部位、大小、形态基本一致，无脑外转移和颅外扩散，经免疫组织化学染色检测S-100蛋白均为阳性。

The study shows that almost all the feldspar in the alkali-granite is perthite, the host-crystal is microcline, the chadcrystal could be either albiter or oligoclase. The Alkali-amphibole is either manganese-magnesia-arfvedsonite or arfvedsonite, and all the alkali-pyroxene is aegirine.

结果表明，该区富碱花岗岩几乎所有的长石均为条纹长石，主晶为微斜长石或高微斜长石，客晶为钠长石或更长石，碱性角闪石为含锰镁质钠铁闪石或钠闪石，碱性辉石均为霓石。

Administration of NGF may treat the spinal cord and periphery nerve injured and improve the function of damage nerve.

神经生长因子是最先发现和被证实的细胞生长调节因子，NGF在神经细胞的增殖，分裂和轴突的生长、递质的合成及细胞的凋亡等阶段均起着重要作用，NGF对中枢和周围神经的损伤均有保护和促进恢复的作用，尤其是NGF促进神经细胞的再生，给予NGF可减轻和改善对神经元的损害和治疗外伤引起的脊髓和周围神经损伤。

Several transient compounds were synthesized by the homo- and heterogeneous reactions of reactive halogen compounds, In-situ ultraviolet photoelectron spectroscopy and photoionization mass spectroscopy as well as theoretical calculations were used to study their molecular structures, stability and molecular orbital properties, their electronic structures and geometric structures were obtained for the first time; Simultaneously, the electronic structure and thermal dissociation of acetyl peroxynitrate and trifluoroacetyl peroxynitrate which have great importance in the atmospheric chemistry were studied; The substituent effects of series of halopyridines and halothiophenes were studied by the ultraviolet photoelectron spectroscopy method for the first time. The atmospheric chemical reaction between peroxyacetyl radicals with IO radicals as well as the dissociation of the most stable isomer of CH3COIO3 were calculated by density functional theory, it was found that the CH3COOIO2 isomer may be act as a new reservoir of inorganic iodine in the stratosphere.

通过活性卤素的系列均相与非均相化学反应合成了几种瞬态物种，采用原位紫外光电子能谱和光电离质谱结合量子化学理论计算对化合物的分子结构、稳定性以及分子轨道特性进行了研究，首次获得了这些物种的电子结构和几何结构的信息；同时研究了大气中有重要作用的乙酰过氧硝酸酯和三氟乙酰过氧硝酸酯的电子结构性质及热解过程；采用紫外光电子能谱手段首次研究了系列卤代吡啶和噻吩的取代基效应；通过量子化学理论计算研究了乙酰基过氧自由基与IO自由基的大气化学反应及其最稳定异构体CH3COOIO2的解离，发现该物种可能是无机碘化合物在平流层中的储库物种。

Domenstic and abroad academicians have disclosed the influence mechanism of these factors from different aspects, including the gene polymorphism and gene mutation in genetics, which are a susceptible factor for cardiovascular complication in type 2 diabetes patients; the dysfunction of endotheliocyte, the metabolic disorder of lipid, and dysfunction of vascular smooth muscle, which can lead to the formation of arteriosclerosis;the formation of immune complex,which can also accelerate the destruction of artery paries;the sctivation of protein kinase C and the dysfunction of platelet, which may ultimately result in the formation of thrombus and influence the function of cadiac muscle cells.

其中主要包括：遗传学方面的基因多态性和基因突变，二者均是2型糖尿病合并心血管疾病的一个易感因素，内皮细胞功能障碍、脂质代谢异常及血管平滑肌细胞功能异常均可导致动脉粥样硬化的形成；免疫复合物的形成可加速动脉壁的破坏；蛋白激酶C的激活及血小板功能受损最终导致血栓形成并影响心肌细胞的功能。

It was concluded that the photosensitization of PPa in liposomal media was different from that in homogeneous systems.

这揭示，PPa在非均相脂质体体系中的光敏作用有别于均相体系，具有新特征。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
