1 Discovery of secondary freshwater calciteFROM well ZJ-23, around 22 m of condensed limestone has been found in member Chang-3 ofthe Upper Triassic Yanchang Formation. Electric log reflects high resistivity, higher densityof rock and lower values of natural gama, with calcite content of 40%—80%. Observation da-ta of 11 core wafers from 883. 05—887.20 m of the well demonstrate that high-angle struc-tural fracture (2 mm wide) and micro-fracture are relatively developed and fully or half

Extraskeletal myxoid chondrosarcoma (EMC) is a lowgrade sarcoma characterized by developing metastases and local recurrence in high rate. It is mainly deep seated in the proximal extremities. The most common metastatic sites are the lungs, soft tissues, lymph nodes, bones and the brain. To our knowledge, no case of clearly defined EMC has been reported to date developing a metastasis in the pancreas. We describe a case of a man suffering from EMC who developed a single pancreatic metastasis 20 years after the initial diagnosis. A 49-year-old man was submitted to surgical excision of an EMC, in left thigh, 20 years ago. Fourteen years after the initial diagnosis a local recurrence in left thigh occurred. Multiple lesions of metastatic origin, in both lungs, were excised via thoracotomies until the time being. In 2003, as a part of a periodically performed imaging control, an abdominal CT scan was performed revealing a solid lesion in the pancreas. Distal pancreatectomy was performed. The histopathology of the excised specimen proved to be the one of metastatic lesion of EMC. The above-mentioned case of EMC is, as far as we know, the first one described developing a certain pancreatic metastasis.

Gastrointestinal duplication is an uncommon congenital abnormality in two-thirds of cases manifesting before the age of 2 years. Ileal duplication is common while colonic duplication, either cystic or tubular, is a rather unusual clinical entity that remains asymptomatic and undiagnosed in most cases. Mostly occurring in pediatric patients,colonic duplication is encountered in adults only in a few cases. This study reports two cases of colonic duplication in adults. Both cases presented with rectal bleeding on admission. The study was focused on clinical, imaging,histological, and therapeutical aspects of the presenting cases. Gastrografin enema established the diagnosis in both cases. The cystic structure and the adjacent part of the colon were excised en-block. The study implies that colonic duplication, though uncommon, should be included in the differential diagnosis of rectal bleeding.

The photoelectrochemical behaviour of the multilayer semiconductive electrode(GaAs/AlxGa1-xAs)with the structure of N+NP and N+NPP was studied in Na2SO4 solution. Compared with single kind semiconductor electrode, the commposite one has broader photoresponse spectral region and larger open-circuit photovoltage,consequently gives higher solar energy conversion efficiency.

Intrahepatic cholangiocarcinomas (ICC) are neoplasms that originate from cholangiocytes and can occur at any level of the biliary tree. Surgical resection is the current therapy of choice for this highly aggressive cancer. However, the 5-year survival still is poor, with high recurrence rates. Due to the intrahepatic growth a signifi cant proportion of patients present with advanced disease and are not candidates for curative surgery or transplantation. The existing palliative options are of limited benefit and there is a great necessity for novel therapeutic options. In this article we review the role of the phosphoinositide 3-kinase(PI3K)/ AKT and extracellular regulated kinase (ERK) signaling pathways in ICC and present new data on the prognostic value of these protein kinases. Finally, we discuss future upcoming therapeutic options based on targeting these signaling pathways.

The intramolecular photochedcal interaction of a series of bis-coumarinyl compounds with various alkyl chain lengths (An) has been studied in/without the presence of β-cyclodextrin (β-CD) by fluorescence spectroscopy. The results show that both photedimerization andexcimer formation can occur in the respective favourable microenvironments.

THE unique spherical nature and potential application of fullerene have attracted great attention. Their functionalization is in particular an active research field. Many methods are now available for the preparation of fullerene derivatives. The 1, 3-dipole cycloaddition of ylide to fullerene is one of the best known methods. We have recently reported that aminoacid esters can be added to C60 to form fulleropyrrolidine derivatives under photolysis. Our in-
