Gastroesophageal reflux disease(GERD),a common disorder in the West,is less seen in Asian countries.No nationwide epidemiological study of GERD has been conducted in China up to now and the population distribution of GERD remains unknown.Many factors are believed to be responsible for GERD.In addition to some recognized factors,the influences of factors like obesity,smoking and so on are till unclear.Furthermore,GERD is believed to be associated with many diseases.This article reviews the disease distribution,risk factors and associated diseases of GERD.

· The mechanisms of regeneration and protection of optic nerve the represent of central nerves are researched more and more profoundly and extensively in recent years. The retinal ganglion cells protection after injury is stopping or preventing it from apoptosis mainly. The methods include glutamic acid inhibitor, nitric oxide (NO) inhibitor, neurotrophic factor, gene therapy, acupuncture, traditional Chinese medicine and so on. However, there have no any medicines or operations that play definite curative role in the retinal ganglion cells protection after injury up to now. So the ganglion cells protection is at its exploratory research stage,which will shoulder heavy responsibilities.

Glaucoma is a group of irreversible blind eye diseases with specific optic nerve damage and visual field defect. Early diagnosis and treatment of glaucoma is vital for prognosis, but difficult in clinical practice. Macular ganglion cell complex thickness(mGCC) consists of the inner three layers of retina:retinal nerve fiber, ganglion cell and inner plexiform layers, which is glaucoma target tissue so to be measured the thickness of the mGCC as better indicator for early diagnosis in glaucoma. Optical coherence tomography ( OCT ) is a non-contact, good repeatability technique to obtain fast high- resolution images from the anterior and posterior segments of the eye, and it has been widely used in ophthalmology. Spectral- domain ( SD ) OCT allows a higher image resolution and can measure the thickness of mGCC thickness, providing new parameters for the early diagnosis of glaucoma.
