Ocular neovascularization is the primary cause of blindness in a wide range of ocular diseases.The common blinding diseases,including diabetic retinopathy,age-related macular degeneration,infectious keratitis,are all caused by neovascularization.Osteopontin (OPN) is a glycoprotein,which can promote angiogenesis and tissue repair.It is aboudantly expressed in corneal neovascularization,choroidal neovascularization and retinal neovascularization,and promotes angiogenesis.The relationship between OPN and ocular neovascularization provides a new direction in research and treatment of neovascular diseases.This paper reviewed the research progress of OPN and ocular neovascular diseases.

This paper showed that levels of cAMP, PGE_2 in plasma and cAMP in spleen tissue and abdominal cavity macrophages in burned rats are increased (cAMP levels in plasma of the control groups were 24.65?4.59pmol/ml; PGE_2 levels were 309.38?77.64Pg/ml. cAMP levels in plasma of burned groups were 36.58?2.74pmol/ml: PGE_2 levels were 937.50+102.91Pg/ml; P

The purpose of this study was to investigate the effects of gypsum on LP-induced fever and the CSF levels of cAMP and cGMP in rabbits. It was found that gypsum could inhibit the rise of body temperature caused by LP injection, (△T of gypsum +LP group is 0.40?0.08℃, TRI_3 2.55; LP group 0.91?0.06℃, TRI_3 4.99 P

The compound of active ingredients of traditional Chinese medicine (TCM),whose material base is relatively clear,adheres to the concept and advantages of formula compatibility of TCM.Thus,it is an important approach to modern TCMresearch.The significance of research on compound of TCMcomponents/ingredients,as well as the research ideas,is sketched out,and the current research on compound of TCMcomponents for the prevention and treatment of liver diseases is reviewed.The research strategies for TCMcomposition/compound for the prevention and treatment of liver diseases are elucidated from the following two aspects:exploring the compound of TCM components based on clinical TCM compound and studying the composition aiming at the effective components or ingredients of TCM that have been known;it is pointed out that the compatibility of effective TCM components,which provides the method and technology system for innovative drug research,is an innovative research model for inheriting and developing the TCMtheory and is one of the important approaches to modern TCM research.

Metabotropic glutamate receptors (mGluRs) are a family of G protein coupled receptors linked to modulation of ion channel functions and multiple second messengers. These receptors are widely distributed throughout the basal ganglia (BG). Studies have demonstrated that these mGluRs subtypes located at various synapses in BG could modulate the release of dopamine and glutamate which correlates with brain area,the subtype selectivity and concentration of the ligands. Metab otropic glutamate receptors have been proposed as potentially new therapeutic targets for Parkinsons disease by providing a method of pharmacologically regulating neurotransmission in the BG.

The effect of hydroxyprolpyl methylcelulose (HPMC) injected into anterior chamber on filtering angle tissues was studied. Twenty-four rabbits were randomly divided into two groups: the experimental group included 40 eyes receiving HPMC which was injected into anterior chamber and the control group included 8 eyes (one served as normal control and the remaining were injected with balanced salt solution). According to the intaocular pressure (IOP) was normal or elevated ,the experimental group was further divided into group A and B. The tissul specimen of filtering angle were collected to perform pathological examination at 5 days, 3 weeks ,and 10 weeks after injection.During the early period, in groupA,the trabecular meshwork dilated slightly, the vacuoles increased in endothelial cells of inner wall of Schlemm's canal. In group B, the space of trabeculum broadened, there were accumulation of collagen and intercellular fibrosis, the vacuoles significantly increased in endothelial cells of inner wall of Schlemm's canal. But the change mentioned above all recovered to normal appearance on the later stage of long term following observationHPMC injected into anterior chamber may cause temporary elevation of IOP and pathological change of filtering angle, but the change was reversible. HPMC is not toxic or destructive to the tissues of anterior chamb angle.

The treatment of myopic amblyopia and myopic anisometropic amblyopia is difficult and usually resultless and it has been the obstacle of amblyopic treatment. Corneal contact lens, corneal refractive surgery and phakic intraocular lens as new methods can significantly improve visual acuity of patients with high myopic amblopia and myopic anisometorpic ambyopia. For correcting myopia and myopic anisometropic amblyopia it provides a new method. This paper discusses the availibility and safty of above methods for the treatment of myopic amblyopia and myopic anisometropic amblyopia.

Based on Career-Life-Cycle theory and practical experiences,this paper analyzed characters and varied requirements in scientific research during doctors' career development,and discussed the way and effects to construct talent cultivation mode of Research-Life-Cycle for doctors in hospitals.

Objective: To investigate whether initial periodontal therapy may affect the presence of oral Helicobacter pylori(Hp), and to compare the genotype of Helicobacter pylori in oral cavity and that in stomach. Methods: 56 patients with gastric Hp and periodontitis were enrolled in this study. PCR was carried out to identify the presence of Hp in the samples before and after initial periodontal therapy(group 1) or medicine therapy(group 2). DNA sequence of PCR products of 5 patients and 1 Hp infected patient's relative was compared and analyzed. Results: Four weeks after medicine therapy, the rate of Hp in oral cavity was singnificantly lower in group 1 than that in group 2 (3.0% vs 26.1%, P
