Preliminary in vitro and in vivo assessment of a new targeted inhibitor for choroidal neovascularization in age-related macular degeneration.

Choroidal neovascularization (CNV) in age-related macular degeneration usually causes blindness. We established a novel targeted inhibitor for CNV in age-related macular degeneration. The inhibitor CR2-sFlt 1 comprises a CR2-targeting fragment and an anti-vascular endothelial growth factor (VEGF) domain (sFlt 1).

Clinical epidemiology of posttraumatic epilepsy in a group of Chinese patients.

Objective: To explore the incidence, types of onset, and risk factors of posttraumatic epilepsy (PTE).

Methods: This is a retrospective follow-up study of patients discharged from the Affiliated Hospital of the Medical College of the Chinese People's Armed Police Forces between September 2004 and September 2008 with a diagnosis of traumatic brain injury (TBI).

Results: Complete clinical information was available on 2826 patients.

Effects of osthole on apoptosis and TGF-beta1 of hypertrophic scar fibroblasts.

Osthole, 7-methoxy-8-[3-methylpent-2-enyl]coumarin (1), was extracted from a Chinese herb Cnidium monnieri (L.) Cuss. It showed immunity strengthening, anti-tumor, anti-hepatitis, and anti-osteoporosis activities in previous studies.

Therapy for acute pancreatitis with platelet-activating factor receptor antagonists.

Acute pancreatitis (AP) causes release of platelet-activating factor (PAF), which induces systemic effects that contribute to circulatory disturbances and multiple organ failure. PAF is a cell surface secretion of bioactive lipid, which could produce physiological and pathological effects by binding to its cell surface receptor called platelet-activating factor receptor (PAF-R). Studies showed that PAF participate in the occurrence and development of AP and administration of platelet-activating factor receptor antagonists (PAF-RAs) could significantly reduce local and systemic events after AP.

[Factors of avascular necrosis of femoral head and osteoporosis in SARS patients' convalescence].

Objective: To explore the factors affecting the pathogenesis of avascular necrosis of femoral head and osteoporosis of SARS patients during convalescent stage.

Methods: The clinical data of 40 SARS patients, 12 males and 28 females, aged 29 +/- 9, hospitalized from April to June 2003, were reviewed, targeted on the use of glucocorticoids. Three months after the discharge ELISA and indirect immunofluorescent antibody (IFA) assay were used to detect the serum IgG.

[The effects of the receptor antagonist of glutamic acid on the brain tissue of severely scalded rats].

Objective: To explore the influence of glutamic acid on burned rat brain tissue and the effects of the receptor antagonist of glutamic acid.

Methods: Rats inflicted with 30% TBSA III degree scalding injury were taken as the model. The water content, K(+), Na(+), Ca(2+), Mg(2+), nitric oxide metabolites (NO(2)(-)/NO(3)(minus sign))concentrations of scalded rat brain were determined at 2, 6, 12 and 24 postburn hours (PBH).
