The mechanism which cellular immune function of portal venous blood was much lower than that of peripheral venous blood in patients with PLC wasunclear. We believed that spleen and gastrdenteric system may play an impartant role.展开更多

(A) If X is λ-paracompact and every X σ is normal and δθ-refinable, then X is normal and δθ-refinable; (B) If X is hereditarily λ-pa racompact and every X σ is hereditarily normal and hereditarily δθ- refinable, then X is hereditarily normal and hereditarily δθ-refiable .展开更多
