The nanoplex were smaller than the unmodified nHAP; thelipiodol/nanoplex emulsion, with the mean diameter at 75±11.8nm can disperse moreuniformly and be more soluble and stable, contrary to the unmodified nHAP and nanoplex Conclusion: Nanoplex/pDNA mass ratios greater than 15 had exhibited completepDNA absorption onto positive charged polyplex and pDNA protection from thedestruction of nucleinase in rabbit serum. Unmodified nHAP may can\'t induce effectivegene delivery.PartⅡThe construction of the recombint eukaryotic expressive vector ofwild-type human p53 and RbObjective: To construct the recombint eukaryotic expressive vector of wild-type humanp53 and Rb by utilizing the theory of molecular medicine.

结果nHAP颗粒本身大小小于100nm，但由于颗粒表面本身带负电，不能包括有效地结合及保护DNA；经Ca~(2+)修饰后，颗粒可带正电，可一定程度地结合和保护DNA，但聚合物本身的中性电与带负电的细胞膜结合，而且本身的颗粒则变地容易聚集而成为很大的颗粒，也不利于细胞的吞噬；经PLL修饰后，颗粒溶解性提高，直径变小，表面带正电，电泳结果显示PLL-nHAP颗粒可包括有效地结合和保护DNA免受兔血清的破坏，而且复合物表面的正电也包括有利于与细胞膜的结合与吞噬。

The catalyst of RFG-DQ and DOCO(1) can both reduce the olefine content of gasoline dramatically, with the yield of LPG ,diesel and coke reduced and the yield of gasoline increased, as well as octane number of gasoline reduced more greatly.The olefine content of gasoline can be effectively reduced by optimizing the operation condition, lowering the reaction temperature, increasing the catalyst-to-oil ratio and using catalyst, which can improve the gasolines quantity and upgrade the gasoline.

Sustained AF could be induced easily in all dogs during vagal nerve stimulation in vivo both before and after isolation of all PVs with encircling lesions created by a bipolar radiofrequency ablation clamp device. PV elimination had no effect on atrial effective refractory period or its responses to cholinergic stimulation. Autonomic ganglia were identified by bradycardic and/or tachycardic responses to high-frequency subthreshold local stimulation. Ablation of the autonomic ganglia overlying all PV ostia suppressed the effective refractory period-abbreviating and AF-promoting effects of cervical vagal stimulation, whereas ablation of only left- or right-sided PV ostial ganglia failed to suppress AF.

无论是在双极环状消融所有PV之前或之后，在体刺激颈迷走神经节过程中持续性房颤在所有犬均能轻易被诱导出，PV切除对心房肌的有效不应期或对胆碱的反应均没有影响，通过对高频的域下刺激发生快速或慢速反应来鉴定自主神经节，消融叠加于PV口部的自主神经节能抑制有效不应期的缩短、和刺激颈迷走神经诱发的房颤促进作用，而仅消融左或右侧PV口部的自主神经节却不能抑制房颤。

Objective To establish rat model with polycystic ovary with two different methods:testosterone plus human chorionic gonadotropin and progestogen plus HCG,compare the rat models induced by testosterone plus HCG with the patients with polycystic ovary syndrome in the aspects of ovarial morphous and gonadal hormone,and investigate whether testosterone with HCG is the effective method to establish rat model with polycystic ovary syndrome,than compare two methods(T+HCG and P+HCG)finally to draw a conclusion if there are any difference or similary between the two methods and which one is more ideal and convenient.Methods 60 SD female rats of 23 days were divided into three groups in random.

目的 本实验用睾酮联合绒毛膜促性腺激素及炔诺孕酮联合HCG两种方法分别建立多囊卵巢大鼠模型，将模型鼠的卵巢形态及血清激素方面改变与人类多囊卵巢综合征的病理改变加以比较，探讨睾酮联合HCG是否是建立多囊卵巢大鼠模型的有效方法，并比较两种造模法是否存在异同点，判断哪一种造模方法更为理想及简便有效。

The effect of the SDT／S on the properties of NR compound was investigated The results showed that SDT／S plays the advanced role in NR compound,in order to keep the vulcanizate properties level as before may decrease some accerlator;the physical properties of overcured vulcanizate,the adhesion strength of optimum cure or overcured valcanizate between rubber and cord were improved by adding 2 phr of SDT／S to NR compound.
