AIM:To study different approaches to caudate Iobectomy with'curettage and aspiration'technique using Peng's multifunctional operative dissector(PMOD).The surgical procedure of isolated complete caudate Iobectomy was specially discussed. METHODS:In 76 cases of various types of caudate Iobectomy,three approaches were used including left side approach,right side approach,and anterior approach. Among the 76 cases,isolated complete caudate Iobectomy was carried out in 6 cases with transhepatic anterior *** surgical procedure consisted of mobilization of the total liver,ligation and separation of the short hepatic veins,splitting the liver parenchyma through the Cantlie's plane,ligation and division of the caudate portal triads from the hilum,dissection of the root of major hepatic veins, detachment of the caudate lobe from liver parenchyma. RESULTS:The mean operative time was 285±51 min, the mean blood loss was 1 600 *** severe complications were *** the 6 cases receiving isolated complete caudate lobectomy with transhepatic anterior approach,one case died 17 months after operation due to disease recurrence and liver failure,the other 5 cases have been alive without recurrence,with one longest survival of 49 months. CONCLUSION:The choice of approach is essential to the success of caudate *** PMOD and'curettage and aspiration'technique can delineate intrahepatic or extrahepatic vessels clearly,caudate lobe resection has become safer,easier and faster.

知识产权公共政策协同运行模式是将协同学的基本原理运用于知识产权公共政策体系这个复杂系统的构建和运行管理中的一种更高效的政策运行模式。与传统模式相比较,知识产权公共政策协同运行模式更注重宏观政策所体现的序参量管理,以及决策部门之间的信息交互流动,强调借助政策协同机制使各政策子系统相互作用和影响形成政策协同效应,进而产生政策系统的自组织,使系统实现从无序到有序的转变。

Background: Wounded personnel who work at sea often encounter a plethora of difficulties. The most important of these difficulties is seawater immersion. Common medical dressings have little effect when the affected area is immersed in seawater, and only rarely dressings have been reported for the treatment of seawater-immersed wounds. The objective of this study is to develop a new dressing which should be suitable to prevent the wound from seawater immersion and to promote the wound ***: Shark skin collagen(SSC) was purified via ethanol de-sugaring and de-pigmentation and adjusted for p H. A shark skin collagen sponge(SSCS) was prepared by freeze-drying. SSCS was attached to an anti-seawater immersion polyurethane(PU) film(SSCS+PU) to compose a new dressing. The biochemical properties of SSC and physicochemical properties of SSCS were assessed by standard methods. The effects of SSCS and SSCS+PU on the healing of seawaterimmersed wounds were studied using a seawater immersion rat model. For the detection of SSCS effects on seawaterimmersed wounds, 12 SD rats, with four wounds created in each rat, were divided into four groups: the 3 rd day group, 5 th day group, 7 th day group and 12 th day group. In each group, six wounds were treated with SSCS, three wounds treated with chitosan served as the positive control, and three wounds treated with gauze served as the negative control. For the detection of the SSCS+PU effects on seawater-immersed wounds, 36 SD rats were divided into three groups: the gauze(GZ)+PU group, chitosan(CS)+PU group and SSCS+PU group, with 12 rats in each group, and two wounds in each rat. The wound sizes were measured to calculate the healing rate, and histomorphology and the immunohistochemistry of the CD31 and TGF-β expression levels in the wounded tissues were measured by standard ***: The results of Ultraviolet-visible(UV-vis) spectrum, Fourier-transform infrared(FTIR) spectrum, circular dichroism(CD) spectra, sodium

为建立兼顾公平与效率的流域生态补偿机制,科学合理的测算生态补偿额,从经济学角度构建基于排污权的流域跨界生态补偿模型。以福建省境内的闽江流域为例,分别测算流域各城市2011～2015年理论排污权和排污权损失,核定生态补偿额。结果表明:各城市生态补偿总额存在明显的年际变化,福州作为闽江流域的下游城市,其生态补偿总额根据上游城市南平、泉州、宁德的污染物排放情况而定;南平、三明作为闽江流域中游城市,生态补偿总额根据上游城市以及自身的水污染物排放情况而定;泉州、龙岩、宁德作为闽江流域上游城市,生态补偿总额主要根据自身排放的污染物情况而定。研究结果可为福建省乃至全国跨界流域补偿总量测算的研究实施提供参考借鉴。结合闽江流域生态补偿测算结果,提出了明确生态补偿主客体、兼顾上下游利益、建立流域排污权制度等完善流域生态补偿机制的建议。
