International Natural Gas Market and Prospects for Sino-Russian Cooperation

During the visit by Russian President Dmitri Medvedev to China in September 2010, the China National Petroleum Corporation （CNPC）and Gazprom signed a ＂Protocol on Basic Conditions of Natural Gas Supply to China＂ covering Russian natural gas supply to China through the western pipelines. Detailed contracts will be signed by both sides before the middle of 2011.

试论工程监理对首都建设工程施工现场的环境管理

从北京市建设工程的实际情况出发,从法规、标准、技术、经济等层面,对工程监理在施工现场实施环境监督管理,特别是施工扬尘控制监督的举措进行了探讨。结果表明,该举措意义重大、技术经济可行,但是尚需要在法规、标准方面得到进一步的支持。     

中国现行独立董事制度的批判

思维混乱、依据的缺乏及与现有制度的冲突,使独立董事制度在我国的存在具有很大的不合理性。现行独立董事制度在适用范围、产生机制、权力配置、任职保障等方面有很多缺陷。独立董事制度实施的情况难以令人满意,还导致了监事会制度进一步被淡化。     

谈"产学结合"的有效运作

“产学结合”是培养应用型人才的主流模式。高职教育应从“产学结合”的内涵和定位入手,细化“产学结合”运作流程,明确“产学结合”组织保证、教学保证、资金保证,做好学生的组织与安排工作,取得政府支持并与企业双赢合作。     

国际气候谈判中的国家利益与中国的方略

20世纪80年代以来,随着全球气候的变化,人与自然的矛盾日益加剧。为了维护人类的共同利益,发达国家与发展中国家走到了一起,围绕如何保护气候、限制温室气体排放,展开了谈判、交涉等一系列的活动。这其中有合作也有冲突,全球气候协作的国际进程有曲折也有进展。它一方面形成了各国利益的互补与联系,促成了国际合作,另一方面也引发了国际间的对抗与冲突。这其间,困扰人们的是国家利益和人类共同利益之间的“囚徒困境”,体现的是国家利益至上原则。     

Flawed Mediation and a Compelling Mission: Chinese Diplomacy in the Six-Party Talks to Denuclearise North Korea

This paper examines China’s role in the Six-Party Talks, a multilateral initiative with the aim of denuclearising North Korea. As North Korea’s behaviour has become increasingly provocative, evidenced by the Cheonan and Yeonpyeong Incidents and the newly unveiled uranium enrichment plant at Yeonbyon, China’s indecision in dealing with the deteriorating situation has dramatically undermined Beijing’s ability to continue successfully to play the leading mediator role. Yet if China fails to take decisive action now, the consequences could be dire. Further deterioration in North Korea’s behaviour could trigger a nuclear arms race, severely hamper regional economic development and even create a geopolitical split in East Asia, leading to a confrontation between the US, South Korea and Japan acting together on one side, and China, Russia and North Korea aligned on the other. The factors that have prevented China from making further progress in the diplomatic process are many and various and this paper will reveal the complexity of the North Korean issue for China. Foreign academics and policy makers have tended to attribute China’s indecision over North Korea to China putting its own security interests first. But this is far too simplistic a picture of the complex relationship that China has with North Korea. There are a host of factors at work that need to be taken into account to understand the present impasse in the diplomatic process. These factors include China’s emotional ties to North Korea and empathy with its position as the weakest party in the Talks, the conflicting attitudes within the Chinese government itself towards the North, and the competing interests and lack of trust between the different stakeholders. It seems that for the foreseeable future, the North Korean issue will continue to plague Chinese foreign policy until all the parties involved act as a collaborative body to reach a consensus on how to resolve the situation.     

猪血凝性脑脊髓炎病毒SYBR Green Ⅰ实时荧光定量PCR检测方法的建立

根据GenBank中的猪血凝性脑脊髓炎病毒(HEV)S蛋白基因的保守序列设计合成1对特异性引物,经PCR扩增S基因并构建含有该基因片段的重组质粒,将该重组质粒作为阳性标准品,建立了检测HEV的SYBR Green Ⅰ real-time PCR方法。结果显示,该方法线性关系良好,相关系数为0.994;敏感性高,检测下限为1.6×104 copies/μL;特异性强,与牛冠状病毒、伪狂犬病病毒和猪繁殖与呼吸综合征病毒不发生交叉反应;并且重复性好,组内、组间的变异系数均小于2%。应用该方法对采集的20份疑似HEV感染病料进行检测,其中16份为阳性,而用常规PCR检测同样的样品,仅8份为阳性。表明建立的SYBRGreen Ⅰ real-time PCR方法具有快速、特异、敏感、重复性好等优点,可用于临床上HEV的检测及定量分析。     

氟苯尼考琥珀酸钠的制备及其在家兔体内的药代动力学特征

用DMAP法制备氟苯尼考琥珀酸钠(Fl-SNa)。将6只家兔分别单剂量肌肉注射氟苯尼考和Fl-SNa,然后采用高效液相色谱(HPLC)法检测血药浓度;用DAS2.0药代动力学程序计算药代动力学参数。结果显示,成功制得Fl-SNa;给家兔单剂量注射氟苯尼考和Fl-SNa后,主要的药代动力学参数Cmax分别为8.863mg/L±0.254mg/L和7.363mg/L±0.085mg/L,tmax分别为1.0h和2.0h,AUC0-∞分别为28.851mg/L.h±0.494mg/L.h和39.187mg/L.h±0.413mg/L.h。结果表明,Fl-SNa达峰时间延长,峰浓度降低,生物利用度大大提高。证明高效液相色谱法准确、灵敏,适用于氟苯尼考血浆浓度的测定;制备的Fl-SNa与氟苯尼考相比生物利用度显著提高。
