Some spore-pollen assemblages of late Trias and the youngest zircon of 225Ma were also obtained in this type.Deriveration of the ore is from the upper crust according to the features of trace elements,zircorn U-Pb age and initial value of ~(87)Sr/~(86)Sr.It has not any charateristics of the mantle.

底辟-侵位角砾岩是本次工作新发现的，它在空间上与构造-膏溶角砾岩密切伴生，剖面上呈脉状或火焰状分布，局部呈脉状穿刺于围岩中，其胶结物中含有晚三叠世的孢粉组合，最年青锆石的年龄为225Ma，角砾岩本身是铅和锌的富矿体。

发现形成一种新的三元配合物，并用来解释在吐温－80水溶液中硫氰酸铋为一种灵敏的显色反应。

By following the "self-assisted molecular editing" protocol first established in our labs,a number of Aphos ligands were efficiently prepared from a single starting material and they were screened for catalytic efficacy, leading to the discovery of the best-performing Aphos appended with a 3-nitrophenyl group at the C4 position.Combination of this Aphos with Pd_2 offers a precatalyst for successful cross-coupling of unactivated aryl chlorides with aryl boronic acids at room temperature.The reactions took place under mild basic conditions to produce the products in high yields.

通过我们首次提出的&自助分子剪裁&的概念从单一起始物快速合成和筛选了一系列膦配体，并发现C4位含3-硝基苯基的的膦配体和醋酸钯联用可以在室温下顺利地催化不活泼氯代芳烃和芳基硼酸的偶联反应，反应条件温和且产物收率很高。

In order to further investigate the relationship of SP and ESCs, we design two level experiments —in vitro and in vivo. In vivo, firstly, We establish the nomal rat full-thickness wounds model, and employ integrin β1 keratin 19(K19)、 keratin 15(K15)、 Brdu as ESCs markers to conform the existence of ESCs in the granulation tissue of Group Capsaicin (rats were subcutaneously injected capsaicin pre-injury to damage sensory neuron and block the secretion of neuropeptides), Group Control, and Group SP (rats were injected SP in the wound postinjury). Secondly, as diabetic skin lacking of SP due to extensive pathological changes of sensory ending, we make a hypothesis:one of the main reason of unhealing wounds on diabetic patients could be insufficient SP which lead to fewer ESCs recruitment around wounds.

在此基础上，为进一步验证P物质促进表皮干细胞向肉芽组织中募集这一重要发现，本研究首先利用β1整合素、K19、K15等干细胞标记物以及干细胞慢周期性的特点，分别在体观察了正常皮肤伤口愈合过程中SP组、辣椒素组采用特异性感觉神经毒性药物辣椒素(capsaicin皮下预注射化学性除去感觉神经从而阻止神经肽分泌、对照组肉芽组织中表皮干细胞分布特点；其次，糖尿病患者皮肤存在周围末梢神经的损伤和神经肽含量的下降，这是否会导致糖尿病皮肤伤口创缘表皮干细胞募集不足，继发伤口难愈？

The findings of the newly identified goose paramyxovirus strain GPMV/HBexperimental infection were as follows: The challenge caused high morbidity and highmortality.The clinical signs included severe depression, decreased appetite or anorexia,white,yellow and green diarrhea, with neural symptoms;pathological changes showed thathaemorrhage and ulceration of intestine mucosa, necrosis of spleen and pancreas,andedema of liver and kidney, uratic deposition in kidney.Eosinophilic inclusion bodies werefound in the cytoplasm of pancreas and a large quantities of fiber protein were found inintestine. Lots of hemosidefin was found in some area of liver and kidney. A number ofT、B lymphocytes reduced sharply in spleen,lymph nodes in dead geese. Transmissionalelectron microscope showed that some cells had the morphological characteristics ofmitochondria swelling, morphological changes were condensation of nuclear chromatininto dense masses,followed by its marginating against the nuclear envelope, andespecially concentration of cytoplasm association with lots of lipid droplet.
