The second Zagreb index of a graph G is an adjacency-based topological index, which is defined as ∑ uv∈E(G) (d(u)d(v)), where uv is an edge of G, d(u) is the degree of vertex u in G. In this paper, we consider the second Zagreb index for bipartite graphs. Firstly, we present a new definition of ordered bipartite graphs, and then give a necessary condition(More)
CD105 is rich in endothelium cells and is involved in angiogenesis. Higher microvascular density of tumor is also related to the prognosis in a variety of cancers. In this present study, patients with positive N classification, advanced T classification, advanced TNM stage, extracapsular spread of lymph nodes (ECS), and perineural invasion had significantly(More)
BACKGROUND Adefovir Dipivoxil (ADV) is an important agent to suppress hepatitis B virus (HBV) replication with suboptimal effect on virological and serological response. To optimize Adefovir therapy in chronic hepatitis B (CHB) patients with hepatitis B e antigen (HBeAg) positive, we studied the baseline parameters and on-treatment HBV DNA for favorable(More)
