Angiogenesis is an important pathophysiological process of body response after cerebral ischemia.Angiogenesis is activated in a few hours after cerebral ischemia.It can promote neuronal remodeling and neurological function recovery.Studies have shown that the microvessel density is positively correlated with the long-term survival rate in patients with stroke after cerebral ischemia.This article reviews the regulatory mechanisms and imaging evaluation of angiogenesis after cerebral ischemia.

On hundred cases of B—hepatitis were treated by self—formulatel B—hepatitis No.1 granules made of traditional drugs.A control group of100 cases were treat-ed with Jiaosanxian(scorched triple ingredients,con-sisiting of hawthorn,malt.and membrane of chickengizzard).Resultsshowed that,in the experimentedgroup,the lowering of transaminase,inhibition ofvirus duplieation and improvement of globulin ratioareall—superior to the control group.The resultswere also verified bylaborarory experiments.

Ischemic stroke is a disease with high incidence, high disability and high mortality rates. As a key regulator of microglia activation and proliferation, galectin-3 may have dual effects on ischemic stroke. This article reviews the structure and function of galectin-3, as well as its roles in ischemic stroke.

The pathophysiology of ischemic stroke involves the vascular neural network. Cerebral vein is an indispensable part of vascular neural network, which can provide effective drainage pathway and maintain sufficient cerebral perfusion. More and more evidence have shown that the normal function of cerebral venous drainage system may be as important as arterial perfusion for the outcome of patients with ischemic stroke. However, compared with the cerebral artery system, the cerebral venous system has not attracted enough attention. This article reviews the anatomy of cerebral venous system, the imaging changes after ischemic stroke, and the possible mechanisms of cerebral venous system involved in ischemic stroke and its related complications.
