目的 探讨股骨近端髓内钉治疗股骨近端骨折的疗效。

Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber. The cells arranged side by side or linked by heads and tails in processes. The ends of S-100 positive cells were flat and expanded, adhering to the fiber as claw-shaped pseudopodium.

结果 采用神经管植块法培养的神经嵴干细胞，免疫细胞化学染色呈现nestin及P75双阳性，将其接种在壳聚糖纤维支架材料上，可见神经嵴干细胞贴附于壳聚糖纤维上生长；S-100免疫细胞化学染色显示，S-100阳性细胞突起的末端呈扁平状膨大；扫描电镜显示，壳聚糖纤维上的躯干神经嵴干细胞为梭形，呈现"端对端"、"肩并肩"排列，伸出爪形伪足贴附于壳聚糖纤维上。

Telomerase TMPYP4 with four good-binding chain is expected to become a new type of telomerase quadruplex stabilizers.

TMPYP4与端粒酶四链体结合较好，有望成为一种新型的端粒酶四链体稳定剂。

Molecular docking study of telomerase TMPYP4 quadruplex stabilization role Abstract: The purpose of ligand TMPyP4 to find telomerase TMPyP4 quadruplex in the best mode.

分子对接法研究TMPYP4对端粒酶四链体的稳定化作用摘要：目的以TMPyP4为配体，寻找TMPyP4在端粒酶四链体上的最佳作用方式。

Malicious users can analyze the source port values generated by the DNS implementation to create an algorithm that can be used to predict the next UDP source port value used for a query message.

恶意用户可以分析源端口的价值观所产生的DNS实施创造一种算法，可以用来预测未来的UDP源端口值用于查询信息。

And to a certain application, if interfacial demand is higher, not plan cost, that can use Flash/Flex actually Flex/OpenLaszlo also not likely doorsill has many low, not likely is familiar with JavaScript with respect to very can quick start I want Push information how to do to front Of Javascript activation again, besides be participated in on client end andhtml outside reviving, yi Zheng serves the development of end in your arrival.

而对于某个应用，如果界面要求比较高，又不计成本，那可以用Flash/Flex其实Flex/OpenLaszlo也不见得门槛有多低，不见得熟悉JavaScript就能很快上手我要push信息到前端怎么办 Javascript的再激活，除了在客户端上参与和html的复兴外，亦正在驾临服务端的开发。

NAC4 mmol/L,CAT 80·U〓,NDMS 200μmol/L,and Quin 220μmol/Lcould down-regulate apoptosis as well as P53 expression variously induced by〓.

NAC和CAT不但本身可降低三种细胞的端粒酶活性，并可协同地促进〓对端粒酶的下调作用，而Quin2可抑制这种下调作用。

There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anteriorposterior plane and in Gruen zones 8,9 and 12 in the lateral plane.Typical areas of radiolucency were identified in Gruen zones 2～5 and 10～12 in the middledistal of the stem.Voids appeared in Gruen zones 3～5 and 10～12 in the distal of the stem.

结果(1)按Barrack标准，骨水泥质量A级87.1%，B级11.8%，C级1.1%，无D级骨水泥；(2)按Gruen分区，骨水泥鞘厚度 mm区域多见于正位片上1、2、5区和侧位片上8、9、12区；透亮带多位于假体中远端的2～5区和10～12区；气泡影出现在假体远端的3～5区和10～12区。

There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anterior-posterior plane and in Gruen zones 8,9 and 12 in the lateral plane. Typical areas of radiolucency were identified in Gruen zones 25 and 1012 in the middle-distal of the stem. Voids appeared in Gruen zones 35 and 1012 in the distal of the stem.

结果］(1)按Barrack标准，骨水泥质量A级87.1%，B级11.8%，C级1.1%，无D级骨水泥；(2)按Gruen分区，骨水泥鞘厚度＜2mm区域多见于正位片上1、2、5区和侧位片上8、9、12区；透亮带多位于假体中远端的2~5区和10~12区；气泡影出现在假体远端的3~5区和10~12区。

Meanwhile,the development effect,relative molecular weight and mechanical properties of radiopaque polyurethanes with different iodine content were also studied.

利用X-射线映射对不同封端量聚氨酯的显影效果进行评定；利用DSC和TGA对其热性能进行表征，并评估封端反应对聚氨酯热稳定性的影响；利用噻唑蓝比色法测试了材料的细胞毒性；并对具有不同碘含量聚氨酯材料的显影效果、相对分子量及其分布、力学性能进行了对比研究。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
