Cerebral microbleeds are a research focus in the field of cerebrovascular disease in recent years.Cerebral microbleeds have important influence on recurrent stroke,hemorrhagic transformation,cognitive impairment,and treatment options in patients with ischemic stroke.The article reviews the above aspects.

A kind of coronary stent was made from Nickel-free stainless steel, and the technological process of the stent was studied. A preferable flexible and support force stent was simulated by a commercial finite element code ANSYS with laser cutting, pickling and vacuum annealing. This kind of coronary stent has more superiority. It was also presented that a self designed automatic stent electro-polishing device, which greatly improve efficiency and quality, and the optimization electro-polishing process was put forward.
