2.Prevalence and risk factors of pterygium
International Eye Science 2008;8(5):871-874
Pterygium is a common disorder of ocular surface with unknown etiology and pathogenesis. The epidemiological studies around the world have shown that the prevalence rates range from 0.3% to 37.46%. Pterygium is related to geographic setting, sunlight and ultraviolet exposure,age, gender, economic situation, dry eye syndrome and others. The purpose of this review is to present a summary of the more recent literature about the epidemiological study, paying particular attention to prevalence and risk factors of pterygium.
4.Recent research progress of traumatic optic nerve injury in rat model
International Eye Science 2014;(12):2182-2184
Traumatic optic nerve injury ( TON) is caused by direct or indirect optic nerve trauma, which is one of a serious complication of craniocerebral trauma. lts prognosis poor and usually bring permanent vision damage. At present, optic nerve injury and regeneration is hot in neurobiology research. To build an ideal experimental animal model is extremely important in research and development in the treatment of optic nerve injury. ln this article, we review the methods of making rat models of traumatic optic neuropathy, clinical similarities, advantages and disadvantages of among these models, to provide reference for more experimental study.

Vascular endothelial growth factor(VEGF) is one of the best characterized angiogenic regulators which has many effects in promoting endotheliocyte proliferation and differentiation,increasing the microvascular permeability,inducing the angiogenesis,triggering the growth,survival and migration of tumor cells by combining its specificity receptor (VEGFR).Dysregulation of VEGF expression and signaling pathways therefore plays a pivotal role in the pathogenesis and clinical features of hematologic malignancies,direct and indirect targeting of VEGF and its receptors therefore may provide a potent novel therapeutic approach to overcome bone marrow angiogenesis and multidrug resis-tance thereby improve patient outcome.Recent years,a novel VEGF blockade system using RNA interference attracts more and more people's attention.The small interfering RNA (siRNA) targeting VEGF/VEGFR can completely inhibits the expression of VEGF and induce the silence of corresponding genes.

E2F transcription factor 1 (E2F1) is a major member of the E2F transcription factor family and participates in a wide range of physiological regulatory processes, such as cell cycle, survival, apoptosis, and metabolism. It is proved that the activity of E2F1 is related to the G1/S phase regulation of the cell cycle dependent on tumor suppressor retinoblastoma protein (RB). Recent studies have shown that E2F1 is highly expressed in prostate cancer cells, manifested as an oncogene, and its expression level is closely related to the occurrence, development, and poor clinical prognosis of prostate cancer. Androgen receptor (AR) is the main driving factor for the growth and progression of prostate cancer, and the changes of AR pathway play a key role in the pathological progression of prostate cancer. This article provide a systematic and comprehensive summary on recently published articles to review the role of the E2F1 pathway in prostate cancer.

Objective To explore the relationship between cough variant asthma (CVA) and mycoplasma pneumoniae (MP) infection.Methods Fifty children with CVA were chosen as the experimental group at random,and 50 children with acute upper respiratory infection,who went to the hospital in the same time and with similar age,were chosen as control group.The MP-IgM of children in both groups were tested by the granule agglutinating method.Results Significant difference (? 2=9.013 P

Objective To have knowledge of the exact cause of massive osteolysis. Methods Hair of patients from Xinjiang province was collected and 14 trace elements were determined by inductively coupled plasma mass spectrometryICP-MS. Results Trace elements imbalance in the body of patients was disturbed. Chromium and zinc which are benefit to the growth of the bones were only 0.5 ?g/g and 40 ?g/g respectively that were much lower compared with the healthy persons cadmium was much higher than the limit level in healthy person. Moreover the quantity and ratio of potassium and sodium in the patients were obvious abnormal. Conclusion According to the result of the present paper may be the environmental and dietary factors play an important role in pathogenesis of this disease.
