We studied the geochemical characteristics of the fluid inclusions in the Ordovician carbonates and the Oligocene Shahejie Formation sandstones from 15 wells in the Gangxi Fault Belt, Huanghua Depression. The fluid inclusions are all sec- ondary with gas/liquid ratio of 5%~10%. Base on Raman they are mainly composed of H2O, CO2 and CH4. The homogenization temperatures, combined with burial and geothermal history of the host rock, indicate that the fluid flows in the Shahejie Formation and the Ordovician carbonates were trapped in Neocene. Using a VG5400 mass spectrometer, the helium isotopic compositions were analyzed. Interpretation of results suggested a significant amount of mantle-derived helium mainly accumulating in the intersections of the NWW trending Xuzhuangzi and NE trending Gangxi faults. The maturity of hydrocarbon decreases from the intersection to the outside pointing out that the fluid related to the NWW trending Xuzhuangzi and NE trending Gangxi faults. These factors implied the fluid inclusions have a close relationship to the local tectonic setting. Gangxi Fault Belt experienced intensive Neo-tectonic activities in Cenozoic. Widespread faulted-depressions and strong volcanic eruptions manifested its tec- tonic status of extensional stress field. Mantle uplift caused the movement of magma that carried mantle-derived gases and deep heat flows, the deep-rooted tension faults provided the passages for the gases and heat flows to shallow crust levels.

The stereoselective syntheses of (Z)-methyl 3-perfluoroalkyl-4-(3-carboethoxy-2-furanyl)-3-butenoates 5a-c were investigated. The reaction of (3-carboethoxy-2-fu-ranyl)-methyltriphenylphosphonium bromide 1 with methyl 2-perfluoroalkynoates 2a-c in the presence of K2CO3 at room temperature gives two adducts, (E)-methyl 3-per-fluoroalkyl-4-( 3-carboethoxy-2-furanyl )-2-triphenylphosphoranylidene-3-butenoates 3a-c and (E)-methyl 3-perfluoroalkyl-4-(3-carboethoxy-2-furanyl)-4-triphenylphos-phoranylidene-2-butenoates 4a-c. (Z)-Methyl 3-perfluoroalkyl-4-(3-carboethoxy-2-furanyl)-3-butenoates 5a-c can be synthesized stereoselectively with high yields when an aqueous DMF solution of 3c, 4c or a mixture of 3a-b and 4a-b was heated at 140℃ for 8 h.

In this paper, we first introduce the architecture for a CORBA-based multidatabase system and then give an approach of schema mapping between XML and relational database system. Finally, we investigate the ability to apply the integration of XML with CORBA-based multidatabase systems. This integration extends the ability of a CORBA-based multidatabase system to implement data sharing and interoperability.

973项目"南海大陆边缘动力学与油气资源潜力"在南海南部陆缘采集了两条多道地震剖面,其中NH973-1测线始于南海西南次海盆,横跨了整个南沙地区,至于婆罗洲西北侧,NH973-2测线位于礼乐滩东侧.对地震剖面的解释共划分出7个层序界面,地层可以划分为5个构造沉积单元.根据地震解释对不同时期断层的水平断距进行了测量及分析,获取了与脆性拉张相关的伸展信息:研究区的拉张作用可以分为两期,主要的拉张作用发生在大陆裂谷期(古近纪),形成了一系列的地堑-半地堑以及翘倾断块.第二期拉张作用的时期为漂移期(晚渐新世-早中新世),断层活动强度明显变弱,并主要集中在洋陆过渡带.在南海南部陆缘广泛发育了碳酸盐沉积,其发育的时代和南海的海底扩张时期一致.对位于礼乐滩东西两侧的两条地震剖面伸展特征的分析表明,其根据断层水平断距获得脆性伸展因子与根据深反射地震及重力反演获得的全地壳伸展因子之间存在差异,表明南海南部陆缘的拉张在纵向上并非是均一的,而是取决于深度发生变化.

Objective: The aim of our study was to investigate the expressions of Survivin and Caspase-3 in the hepatocellular carcinoma (HCC) and the paracancerous liver tissues, and define the relationship between the expression and the patients survival rate after surgery. Methods: The expressions of PCNA, Survivin and Caspase-3 were detected by immunohistochemistry. PCNA positive level was used to account proliferating cell nuclear antigen proliferating index (PCNA-PI). The apoptosis index of HCC tissues was detected by TUNEL. Results: The expression of Survivin in HCC tissue was higher than that in paracancerous tissue (P < 0.05), while it was related with portal vein thrombosis, tumor size and histological differentia- tion (P < 0.05). In HCC tissues, the PCNA-PI of the Survivin positive group was higher than the negative (P < 0.05) group, and the AI of the Survivin positive group was lower than the negative group (P < 0.05). The expression of Caspasse-3 in HCC tissue was lower than that in paracancerous tissue (P < 0.05), while it was related with HBsAg and histological differentiation (P < 0.05). In HCC tissues, the average PCNA-PI of the Caspase-3 positive group was lower than that of the negative group (P < 0.05), and the average AI of the Caspase-3 positive group was higher than that of the negative group (P < 0.05). There was negative correlation between the expressions of Survivin and Caspase-3 in HCC (r = -0.242, P < 0.05). The survival rate of the Survivin positive group was lower than that of the negative group (P < 0.05), while that of the Caspase-3 positive patients was higher than that of the negative group (P < 0.05). Conclusion: The expressions of Survivin and Caspase-3 in HCC can reflex the biological behavior of HCC and patients prognosis, they may be new targets of tumor diagnosis and treatment.

BACKGROUND: Resection of the superior mesenteric- portal vein (SMPV) during pancreatoduodenectomy is dis- puted. Although the morbidity and mortality of patients af- ter this operation are acceptable, survival is limited. In this study, we evaluated the morbidity, mortality and survival of patients with ductal adenocarcinoma of the pancreas who had undergone pancreatectomy with en bloc portal vein re- section. METHODS: A total of 32 patients with ductal adenocarci- noma of the pancreas who had undergone pancreatectomy with SMPV resection between 1999 and 2003 were retro- spectively analyzed. In addition, they were categorized in- to two groups according to the invasion of the wall of the portal vein: group A (n =12), extended compression of the wall of the portal vein by surrounding carcinoma without true invasion and group B (n =20), true invasion including intramural and transmural invasion. RESULTS; The morbidity of the 32 patients was 31.25%. There was no operative death, and the overall 1-,3-year survival rates were 59% and 16%, respectively. The mean survival time of patients with microscopically positive mar- gin was only 5. 6 months as compared with 20 months in patients with microscopically negative margin. No diffe- rences in tumor size, margin positivity, nodal positivity, and 1-, 3-year survival rates were observed between the two groups. CONCLUSIONS; If selected carefully, pancreatectomy combined with SMPV resection can be performed safely, without increase in the morbidity and mortality. SMPV re- section should be performed only when a margin-negative resection is expected to be achieved. SMPV invasion is notassociated with histologic parameters suggesting a poor prognosis.
