composite colorectal carcinomas are rare. There are amodest number of cases in the medical literature,with even fewer cases describing composite carcinoma with neuroendocrine and squamous components. There areto our knowledge no reports of composite carcinomamolecular alterations. We present a case of composite carcinoma of the splenic flexure in a 33 year-old cau-casian male to investigate the presence and prognos-tic significance of molecular alterations in rare coloniccarcinoma subtypes. Formalin-fixed paraffin-embedded(FFPE) tissue was hematoxylin and eosin- and mucicar-mine-stained according to protocol,and immuno-stained with cytokeratin(cK) 7,cK20,cDX2,AE1/AE3,chromo-granin-A and synaptophysin. DNA was extracted from FFPE tissues and molecular analyses were performed according to lab-developed methods,followed by capil-lary electrophoresis. Hematoxylin and eosin staining showed admixed neuroendocrine and keratinized squamous cells. Positive nuclear cDX2 expression confirme dintestinal derivation. cK7 and cK20 were *** cells stained positively for synaptophysin and AE1/AE3 and negatively for chromogranin and mucicarmine. Hepatic metastases showed a similar immunohistochemical profile. Molecular analysis revealeda G13D KRAS mutation. BRAF mutational testing wasnegative and microsatellite instability was not *** patient had rapid disease progression on chemotherapy and died 60 d after presentation. Although theG13D KRAS mutation normally predicts an intermed iateoutcome,the aggressive tumor behavior suggests other modifying factors in rare types of colonic carcinomas.

By using the complex variable method and conformal mapping, the diffraction of flexural waves and dynamic stress concentrations in thick plates with a cavity have been studied. A general solution of the stress problem of the thick plate satisfying the boundary conditions on the contour of an arbitrary cavity is obtained. By employing the orthogonal function expansion technique, the dynamic stress problem can be reduced to the solution of an infinite algebraic equation series. As an example, the numerical results for the dynamic stress concentration factor in thick plates with a circular, elliptic cavity are graphically presented. The numerical results are discussed.

The total area of seagrass beds in the coastal seaof South china is about 2400 ha. There are about 8species, such as Halophila ovalis, Halodule uninervisHalophila beccarii, Zostera japonica, Enhalus acoroides, Thalassia hemperichii, Ruppia martime andcymodocea rotundata. These seagrasses have highbiomass and productivity. However, they are subjected to some threats resulting from artificial andnatural factors, especially anthropogenic causes,such as culture of shrimps and fishes, shellfish collection, fishing by means of poisons, electric powerand explosives as well as trawling, artificial pollution,dredging channels, and typhoons natural disaster.
