Investigating the ecology environment and present situation of the endemic Cycas plants to Yunnan, especially the population structure and dynamics of C. Hongheensins and C. tanqingii. The results show that C. hongheensis is a critically endangered species because the number its individuals had decreased by 47% from 1992 to 2002 and no flowering and fruiting tree has found. While the population of C. tanqingii in Xiaoheijiang River is in a status of restoration because there are more young individuals and its age structure takes on the relatively stable shape of pyramid.

And There was no serious complication;②In the course ofinterventional therapy, Direct portal vein angiography demonstrated vena coronaria ventriculi(100%)andgastricveins(65.26%)andvenagastricaposterior38.43%, Angiography demonstrated venacoronariaventriculi communicate esophagus varicose veins, gastric veins and vena gastrica posterior communicategastric varicose veins. vena coronaria ventriculi had only a small percentage of double vein, about30.57%. The sites of vena coronaria ventriculi arising from the portal vein, splenic vein, portosplenic junction, were found in 52.06%、27.39%、20.55% respectively.③12 extrahepaticprotosystemic shunts were found in these patients. Include gastro-nephrosshuntof 3 cases, 7 caseswere splenetic- nephros shunt and 2 cases shown recanalization of umbilical vein .④The averageportal pressure before and after the procedure were 3.87±1.82kPa and 3.64±1.14kPa in 73patients, but to the time of rebleeding, it was 3.96±0.23kPa in the 11 cases.⑤There werethree kinds of variceal outcome: disappearance (54,low degree (19).⑥Spearman logisticanalyse and ANOVAtest shown liver function class, variceal degree of the splenic necrosis area,the blood direction in portal vein before operation and remain small collateral routes were thesignificant factors concerning outcome of varices.⑦The bleeding volume and portalhypertensive gastropathy are main risk factors of rebleeding.⑧The course of livercirrhosis is the risk factor of survival and extrahepatic portosystemic shunt , fine varices are thebeneficial factors to survival.⑨During all cases'followed-up data, the 1, 2, 3, 4, 5 yearcumulative survival rates and rebleeding rates were 17.81%, 28.77%, 38.36%, 43.84%, 47.95%and93.15%,91.78%,86.30%,83.56%,80.82%respectively. Conclusion The interventional disconnection treatment for liver cirrhosis and portalhypertension was designed suitability. It rapidlycontrol bleeding,butpressure of portal vein was notobvious high, perfusion was not low .it was compared with surgery therapeutic that interventionaldisconnection treatment was safe and had a significant clinical effect to hemorrhage and preventfrom rebleeding.

As introduced by relative information, for foreign plants have not solved the joints between over-voltage crosslinked polythene cables so far, the second method should ensure that the crosslinked polythene layer of excessive thickness filled during the later pressed heating sulfuration process has nohuge air hole is produced and left if the thickness extruded at one time is overlarge to 15~30mm during the process of plastic extruding XLPE crosslinked polythene to recover insulation.
第二种方法,据有关资料介绍,由于国外厂家还未解决超高压交联聚乙烯电力电缆的中间接头,在绝缘恢复挤塑XLPE交联聚乙烯的工艺过程中,一次挤出的厚度如果过大,达的时候,要保证填充的过大厚度交联聚乙烯层在后期加压加热硫化工艺中,不产生留存有大的气孔。

Conversely, in our experience,3 after 2 months of CRT, only 30%(48/162) of patients with AF presented with BVP 85% despite implementation of a rigorous rate-control protocol (rate-lowering drugs plus ventricular rate regularisation and trigger mode).
AF患者群中,如果包含这20例&临床行为&类似SR的患者,那么会使得任何结果都变得混淆。考虑到负性心率药物的低使用率和未使用调节心律的药物,报告中涉及的AF人群中的高BVP百分比是惊人的。对快速性心率失常患者恢复正常心室率这一点尤为重要。

The morphology of virions seems to not be change after incubated with the paeonol by electron microscope. The regained infectivity of TMV recovered by dialysis from incubation with paeonol in vitro showed that the paeonol have not direct viricidal effect. The paeonol did not reduce infectivity when applied before TMV inoculation. The paeonol in low concentration can restrain the polymerization of TMV coat protein in vitro. The paeonol did not reduced infectivity of TMV-RNA in vitro. It is proposed that the paeonol inhibited TMV by binding with TMV coat protein to interfere with recognition of a host receptor essential for infection or by interfering TMV-CP polymerization in plants. The anti-TMV activity of low molecular weight chemicals extracted from Polygonum cuspidatum were determined.
丹皮酚与TMV混合,电镜下观察对粒体形态没有影响;TMV与丹皮酚混和后透析可恢复侵染力,表明丹皮酚对病毒粒体并没有直接毒害作用;预先用丹皮酚喷施叶面不影响病毒的侵染,表明丹皮酚未干扰TMV对叶片侵染位点的识别;丹皮酚在低浓度时可阻碍TMV-CP的体外聚合,对TMV-RNA并无体外抑制侵染作用,据此推测丹皮酚对TMV的抑制作用可能主要通过其与TMV-CP结合影响病毒粒体对叶片表面侵染位点的识别,或影响体内TMV粒体的脱衣壳或TMV-CP亚基的体内聚合。

He results show that the virus regained infectivity, and the tannins did not direct viricidal effect. Tannins extracted from Polygonum perfoliatum or Archontophoenix alexandrae seeds showed strongly anti-TMV activities separately. TMV virions seems to be aggregated when TMV incubated with the tannins by electron microscope. It seems that TMV coat protein bind to the tannins based on PAGE. Tannins did not reduce infectivity when applied either before or after TMV inoculation. It is proposed that tannins extracted from the 11 species inhibited TMV by binding with TMV coat protein to interfere with recognition site essential for viral coat protein. Tannins extracted from Euphorbia hirta, P. perfoliatum, P. cuspidatum reduce infectivity when applied immediately in N.
MV分别与这11种植物单宁混合后,通过透析除去单宁后,可恢复大部分侵染力,表明单宁对病毒粒体并无直接毒害作用;TMV与杠板归和假槟榔种子中提取的单宁分别混合后,电镜下观察粒体呈现明显的聚集现象;TMV外壳蛋白分别与这两种植物单宁混合后,聚丙烯酰胺凝胶电泳中CP泳带滞后;单宁在病毒接种前施用未降低TMV对叶片的侵染能力;这些结果表明植物单宁对TMV抑制作用可能是单宁与TMV-CP结合影响病毒对叶片侵染位点的识别而降低TMV侵染性,而这种结合是可逆的。

The higher surface energy of substrate results in higher effective viscosity and thicker ordered molecular film.
从侧面证明了有序液体模型的正确性,即薄膜润滑的成膜性能与近固体表面润滑剂分子的有序度密切相关;足够大的外电压使无序流体膜有序化,生成较高的有效粘度和较厚的油膜,并且二者随着外电压的增加,逐渐趋于稳定;外电场作用下,摩擦系数增大,切断电源后,摩擦系数减小,但不能恢复到未加电压前的摩擦系数值。
