A linear regression analysis of 28 selected tide-gauge stations of the Zhujiang Estuary shows that there has been a tendency of local sea level rise at a rate of 2.028 mm per year. The origin of the variation is significantly attributed to the local tectonic movement of discrepant fault-block. Based on this, four types of relative local sea level changes are classified. According to calculation, half of the fertile land, or 800 km2 of the delta plain will have been submerged by sea water by about 2040. This will yield a significant influence on the economic construction and human activities.

Three problems encountered in the studies on the Yangtze River Estuary-delta are discussed in this *** first involves the sediment supplied and development processes of the ancient beach-ridge plain in the southern side of recent Yangtze River *** second deals with the origin of Lake Taihu depression and the third is concerned with the stages and the differences of the development in Yangtze River Estuary-delta during the last 6000 years.

In the river systems, the environmental change always undergoes a process from quantitative to qualitative change. The upper limit of the qualitative change is called threshold. When the process reaches or goes beyond the limit, the original event series will be replaced by the other event series. Investigations show that the evolution of the Huanghe River alluvial fan and delta has also under gone a process from quantitative to qualitative change. The geometric forms in each process are roughly the same. This threshold of the geometric forms not only provides us a quantitative index for plotting the periodicity of the alluvial fan and delta, but also is of importance for estimation of the trend of natural environmental *** is shown that there are three periodic alluvial fans of the Huanghe River since the middle Holocene and four periodic delta since 1855 A.D., the thresholds of their geometric forms are from 0.93 to 0.94 and from 1.2 to 1.21 *** changing trend in the past and the

There are three major types of tidal channels along the coast of the Huanghe (Yellow) River delta: tidal inlets, tidal creeks, and tidal channels developed from abandoned river channels. The tidal inlets develop mainly in two areas with weak erosion and barrier islands. The tidal channels formed from abandoned river channels mainly developed in the area of the new delta lobes formed since 1934. Tidal creeks developed in the intertidal zone and distributed along almost all parts of the Huanghe River delta coast, but their scales and features are different.

胃癌是一种严重危害人类健康的疾病，我国是胃癌的高发区，每年胃癌新发病例占全部恶性肿瘤发病的17％以上，病死率占全部恶性肿瘤的20％以上。早期胃癌治疗效果较满意，5年生存率95％～100％，但绝大多数胃癌发现时已经进入进展期，预后差，5年生存率仅有30％～40％。大量实验证实，胃癌的生长、转移和预后均与肿瘤新生血管生成相关。因此，抗肿瘤新生血管生成成为胃癌综合治疗的重要策略之一。
