来源: JAMA. 1998年279卷16期1265-72页
Anticoagulation with unfractionated heparin is used commonly for treatment of acute ischemic stroke, but its use remains controversial because it has not been shown to be effective or safe. Low molecular weight heparins and heparinoids have been shown to be effective in preventing deep vein thrombosis in persons with stroke, and they might be effective in reducing unfavorable outcomes following ischemic stroke.

Current guidelines recommend that individuals infected with the human immunodeficiency virus type 1 (HIV-1) be treated using combinations of antiretroviral agents to achieve sustained suppression of viral replication as measured by the plasma HIV-1 RNA assay, in the hopes of achieving prolonged remission of the disease. However, until recently, many drug combinations have not led to sustained suppression of HIV-1 RNA.
