BACKGROUND: Spontaneous rupture of liver tumor is often considered a potentially life-threatening situation. The aim of the present study was to assess re-operation after emergency repair of ruptured liver cancer. METHODS: We reviewed retrospectively five patients who had been admitted within a one-year period and undergone a second operation after emergency repair of primary liver cancer rupture. RESULTS: Five patients (4 males and I female) underwent emergency repair of ruptured liver cancer in local hospitals; three of them received transarterial chemoembolization (TACE). The tumor was in the right hepatic lobe in 2 patients, middle lobe in 1, left median lobe (segment IV) in 1, and caudate lobe (segment 1) in 1. Operative methods included right hemihepatectomy in 2 patients, left partial lobectomy or wedge resection in 1, caudate lobe resection in 1, and middle lobctomy+cholecystectomy+abdominal implant resection in 1. Intra-abdominal chemotherapy was given to all 5 patients. Follow-up showed that one patient died from intrahepatic metastasis and hepatic failure six months after reoperation and that two patients died from extensive intra-abdominal metastases six months later. The remaining two patients have been surviving for 28 months. CONCLUSIONS: Re-operation is indicated for patients with primary liver cancer rupture whose liver function is good and whose foci are localized and operable. Apart from removing the primary foci, it is necessary to clear abdominal metastatic foci, irrigate the abdomen and administer chemotherapy to prolong the patient's life.

In order to improve the toughness of the cured aromatic tetrafunctional epoxy resins, a dlmer rarboxylic acid named dlmer fatty acid （DFA） was used to modify an aromatic tetrafunctional epoxy, N, N, N＇, N＇-tetraglycidyl-2,2-bis [ 4-（ 4-aminophcuoxy ） phenyl ] propane （TGBAPP）. The curing behaviors of DFA- TGBAPP/MNA （ methyl nadic anhydride） systems were studied by differential scanning calorimetry （DSC） method. And the thermal properties of the cured epoxy resin were investigated with the thermo-gravimetric analysis （TGA） and dynamic mechanical analysis （DMA）. Besides, the toughness was characterized with the impact strength tested by charpy impact testing. The results indicated that the modification would improve the curing reactions, and the curing temperatures were decreased with the increasing content of DFA. The thermal properties were not influenced obviously, and the toughness could be improved when the epoxy resin was modified with DFA.

STANDARDIZATION OF SPEECH CORPUS

论规范和引导资本健康发展的社会主义“红绿灯”

作者： li ai-jun Yin Zhi-gang Institute of linguistics Chinese Academy of Social Sciences

Speech corpus is the basis for both analyzing the characteristics of speech signal and developing speech synthesis and recognition systems. In China’s mainland, almost all of the speech research and development affiliations are developing their own speech corpora. We have so many different kinds and a large number of Chinese speech corpora that it is rather important to be able to conveniently share these speech corpora to avoid wasting of time and money and to make the research work more efficient. The primary goal of this research is to find a standard scheme which can make the corpus be established more efficiently and be used or shared more easily. A huge speech corpus on 10 regional accented Chinese, RASC863(a Regional Accent Speech Corpus funded by National 863 Project,4 out of 10 regional data have been distributed until this time) will be exemplified to illuminate the standardization of speech corpus production.

“劳动、资本、国家”三元组合决定了人类现代化历程中国家现代化发展的不同道路。其中,国家作为“管理者”在处理资本与劳动二者关系中发挥协调功能是极其重要的。从根本上来说,中国式现代化既超越了以资本主体化为主导的西方现代化模式,又超越了以国家主体化为主导的苏联现代化模式,重新构建了“劳动、资本、国家”三者的关系,开创了一条以劳动者主体为主导的现代化新道路。如果任由资本野蛮生长必将酿成社会的“政治混乱”,因而国家必须给资本健康发展设置“红绿灯”。唯有坚持党对经济工作的领导,发挥国家作为“管理者”的协调功能,才能让资本的逐利本性服从于并服务于中国特色社会主义的政治初心和价值目的,规范和引导资本健康发展的这样“一个重大政治问题”才能迎刃而解。

数据法学体系是指数据法学在学科上的内部结构及整体构成方式,既包含内容上的逻辑联系,也包括形式上的逻辑构架的研究。数据法学体系建立的价值是为数据法律体系给予指引和实现其内在统一与持续稳定,进而对数据法律体系的健全、完善和... 详细信息

数据法学体系是指数据法学在学科上的内部结构及整体构成方式,既包含内容上的逻辑联系,也包括形式上的逻辑构架的研究。数据法学体系建立的价值是为数据法律体系给予指引和实现其内在统一与持续稳定,进而对数据法律体系的健全、完善和科学化起到促进作用。目前,数据法学体系研究还处在空白状态,我国数据法律体系也未形成,因此本文数据法学体系研究不仅是数据法的理论研究,同时也为数据立法提供理论基础。本文从外在规则体系、价值体系和利益体系三个维度构建了数据法学体系。通过这三个维度的协调和统一实现数据法律的稳定性、体系性、完整性和有效性,并通过利益体系和价值体系实现数据法律的持续性和激励性。数据法学价值体系是数据法学的内在精神,外在规则体系是实现各项规范、制度的整合,数据法学利益体系是实现数据安全和发展的平衡。以此,通过对数据法学体系的建立实现数据法学理论的科学性。

Background Most liver resections require clamping of the hepatic pedicle （Pringle maneuver） to avoid excessive blood loss. But Pringle maneuver can not control backflow bleeding of hepatic vein. Resection of liver tumors involving hepatic veins may cause massive hemorrhage or air embolism from the injuries of the hepatic veins. Although total hepatic vascular exclusion can prevent bleeding of the hepatic veins effectively, it also may result in systemic hemodynamic disturbance because of the inferior vena cava being clamped. Hepatic venous occlusion, a new technique, can control the inflow and outflow of the liver without clamping the vena cava. Methods A total of 71 cases of liver tumors underwent resection with occlusion of more than one of the main hepatic veins. All tumors involved the second porta hepatis and at least one main hepatic vein. ligation or occlusion with serreflnes, tourniquets and auricular clamps were used in hepatic venous occlusion. Results Of the 71 patients, ligation of the hepatic veins was used in 28 cases, occlusion with a tourniquet in 26, and occlusion with a serrefine in 17. Right hepatic veins were occluded in 38 cases, both right and middle hepatic veins in 2, the common trunk of the left and middle hepatic veins in 24, branches of the left and middle hepatic veins in 2, and all three hepatic veins in 5. Thirty-five cases underwent hemihepatic vascular occlusion, 4 alternate hemihepatic vascular occlusion, 23 portal triad clamping plus selective hepatic vein occlusion, and 9 portal triad clamping plus total hepatic vein occlusion. The third porta hepatis was isolated in 26 cases. The amount of intraoperative blood loss averaged （540±2.83）（range 100 to 1000） ml in the group of total hemihepatic vascular occlusion and in the group of alternate hemihepatic vascular occlusion, （620±317）（range 200-6000） ml in the group of portal triad clamping plus selective or total hepatic vein occlusion. All tumors were completely removed. Conclusions
