Acute retinal necrosis syndrome (ARNS) is a group of eye syndrome.Acute uveitis, retinal artery occlusive vasculitis, fused necrotic retinitis and late stage of retinal detachment is the main clinical manifestation.A part of patients may be associated with increased intraocular pressure.The etiology and pathogenesis is still not clear completely and most people think that may be related to the virus infection, which mainly to reflected to be herpes simplex virus (HSV), varicella zoster virus (VZV), EB virus and giant cell virus (CMV) infection.Its diagnosis mainly depends on clinical manifestation, examination and etiological examination.Acute retinal necrosis syndrome is urgent and develops quickly, and it is lack of specific clinical symptoms in early times.By the way, it enjoys high misdiagnosis rate and poor prognosis.It is hard to cure, therefore, it is an important reason for the blindness.Once diagnosed, treatment should be adopted by carrying local and systemic antiviral, preventive laser photocoagulation in time.At the same time, it is essential that vitreous body resection combine with silicone oil tamponade treatment when necessary.The study shows that the effective measures of early treatment will be able to prevent disease progression and improve visual acuity.Therefore, early diagnosis and treatment of acute retinal necrosis syndrome is very important.In this paper, combination of the literature on the diagnosis and treatment of acute retinal necrosis syndrome were reviewed.

GATA3 transcription factor plays an important role in the growth and differentiation of normal breast tissues, and it is also closely related to the tumorigenesis of breast cancer. The roles of GATA3 vary in different breast cancer subtypes. This paper reviews the relationship of GATA3 with normal breast tissue and the tumorigenesis of breast cancer, in an attempt to provide theoretical evidences for future clinical applications of GATA3 in breast cancer.

This study was aimed to investigate the curative effect on external application and rectal instillation with Chinese medicine in the treatment of chronic renal failure (CRF) with acute gouty arthritis (GA). A total of 82 CRF patients with acute GA from the First People's Hospital of Hengyang City were randomly divided into the study group (n = 42), which was treated with external application and rectal instillation with Chinese medicine, and the control group (n = 40), which was treated with prednisone. The comparison was made on symptoms and body signs of GA, blood uric acid, creatinine, creatinine clearance, adverse reaction, and recurrence rate between two groups. The re-sults showed that there was no significant difference on alleviating of joint swelling and pain between the study group and the control group. Compared with pretreatment, the blood uric acid and creatinine were significantly decreased after treatment in the study group (P< 0.01). The creatinine clearance was obviously increased (P < 0.05). There were no significant differences on blood uric acid, creatinine and creatinine clearance in the control group before and after treatment. There was no adverse reaction in the study group. In the one-month follow-up, there were only three recurrent cases in the study group, which were obviously better than the control group (P< 0.01). It was concluded that external application and rectal instillation with Chinese medicine had a good curative effect on CRF with acute GA in the near future with low recurrence rate and no adverse reaction, which was worthy of popularizing in the clinical practice.

Objective To study expression of hypoxia inducible factor 1? (HIF 1?) in the lungs of hypoxic rats and to explore the role of HIF 1? in the pathogenesis of hypoxic pulmonary hypertension Methods Twenty Wistar rats were randomly divided into control group and hypoxia group The models of hypoxic pulmonary hypertension were established by exposure to hypoxia for 4 weeks according to our laboratory protocol Digoxin labelled cRNA probe for HIF 1? was prepared by in vitro transcription Northern blot was performed by using the HIF 1? cRNA probe and In situ hybridization was also conducted with rat lung tissue sections Results Northern blot hybridization showed minimally positive in the lung tissue of control group ,but strongly positive in hypoxia group In situ hybridization analysis with hypoxic rat lung tissue revealed that HIF 1? mRNA was expressed in bronchial epithelial cells (strongly positive reaction) and peribronchial proliferative lymphomatic tissue (weakly positive reaction),casually in alveolar wall cells (weakly positive reaction),but not in pulmonary arterial endothelium and smooth muscle cells Conclusions Our data suggested that chronic hypoxia could induce pulmonary hypertension characterized by pulmonary vascular remodeling HIF 1? mRNA expression was elevated in the lungs of rat under hypoxic condition HIF 1 may be involved in the pathophysiological changes in response to hypoxia and play an important role in the development of hypoxic pulmonary hypertension

ObjectiveTo evaluate the marginal integrity of restoration in two types of mate- rials, or resin- modified glass ionomer cement and polyacid- modified composite resin (compomer). MethodsRestorations of four kinds of material (GC Fuji Ⅱ LC, VitremerTM, Dyract compomer and F2000 compomer) were placed in the facial Class V cavity preparations in forty noncarious human molar teeth. The teeth were randomly assigned to 4 experimental groups of 10 teeth each. After thermal cy- cling( × 20,5 ～55℃ ), the teeth were immersed in 1％ basic fuchsin dye for 24 hours at room tempera- ture. Staining along the teeth restoration interface was recorded. ResultsThe data indicated signifi- cant differences between all the restorative materials for both occlusal and gingival scores ( P=0.026, P = 0. 000)respectively. Further analysis revealed there were statistically significant differences between GC Fuji Ⅱ LC and others on occlusal margins versus Dyract compomer and others on gingival margins. Conclusion Factors such as dental conditioning, rates of water absorption and thermal coefficient were related to microleakage. Resin - modified glass ionomer cement showed less microleakage than polyacid- modified composite resin tested.
