It was found that there were three kinds of mucins (neutral, sialo and sulphomucin in both globoid dysplastic cells and signet ring cells. The percentages of the three kinds of mucins seen in the two kinds of cells were not much different. It was indicated that the altered mucins in the gastric epithelial cells must be a sign of dedifferentiation of the cells and the results of malfunction. The globoid dysplasia type I mainly contained neutral mucin, whereas type II, the acid mucin was predominant, especially the sulphomucin. The CEA positive reaction became stronger as the atypia being remarkable, and the characteristics of distribution of CEA positive particles were similar in the two kinds of cells namely, randomly or disorderly in the cells. Based on the analysis of the results, a conclusion can be made that the variety of mucins in globoid dysplastic cells can be used as a reference point in classification and is not much significant in grading, but the amount of CEA positive matter can be a reference point in grading. The globoid dysplasia is such a lesion with special features in morphology and function manifested in the process of de-differentiation towards signet ring cell carcinoma following the successive action of carcinogens upon the cells of gastric epithelium.展开更多

Although human species have lived on the planet at least 2.5 million years, economic development only appeared around the 1850s. In pursuit of economic development, not all nationalities have been equally lucky. Among more than 200 countries in the world, only dozens of countries are devel oped. Onethird of the world＇s total population of 6.5 billion are living in poverty. In both developing and developed countries, the wealth gap is often obvious. Therefore, eco nomic development is the goal of each country, the aim of each politi cal party, and the wish of all people. However, economic development usually baffles people. As a result, understanding the relationship be tween economic development and human rights protection is a matter of urgency.展开更多

This paper intends to have an analysis of one of Elizabeth Bishop’s poem, The Moose, from the perspective of human-nature relationship showed in it and finds out that a harmonious relationship between mankind and nature can be interpreted from the poem. This paper is divided into three parts, including a brief introduction of the poet and the poem, the analysis of the poem, and the conclusion reached after the analysis.展开更多
