The introduction of highly active antiretroviral therapy (HAART) has greatly changed the pattern and natural history of ocular diseases of HIV-infected patients, resulting from the immune recovery and reduction of opportunistic infections. However, ophthalmic complica-tion continues to be concern in AIDS even in the HAART era, especially in developing areas, where absolute majority of HIV-positive patients live. Lack of test facilities and experience, poor conditions of hygiene, different microbiological environment, absence of effective treatment etc., characterize the ophthalmic manifestation of HIV-infected patients in developing countries from that in developed regions and thus pose a great challenge to the ophthalmic treatment in developing area. Not only varied from region to region, ocular complications are distinctive between adults and children. At the same time, the side effects due to the application of HAART pose their own risks of ocular complication and should, therefore, be given more research attention.

In order to improve the metabolism yield of cordycepin and adenosine,we studied nitrogen sources ,the levels of nitrogen sources and carbon sources,dynamic development in liquid culture ,as well as the total yield of cordycepin and adenosine in culture system through determining the contents of cordycepin and adenosine by HPLC .The results are as follows: not only animal protein but also some plant protein is very good nitrogen sources; in culture solution the suitable levels of nitrogen sources and carbon sources is respectively 3% and 4%; the content of adenosine in culture solution is very low, while it is quite high in mycelia; it is much higher that the total yield of cordycepin in culture solution than in mycelia; when the culture system is oscillated and cultured after 7~9 days, the total yield of cordycepin and adenosine are both high.

AIM: To investigate the effect of Z,E-butylidedephthalide (Bdph) on laser-induced experimental choroidal neovascularization (CNV) in rat model and choroid blood flow in rabbits'eyes.METHODS: Male Brown Norway rats were treated with Nd:YAG laser to break Bruch's membrane. Thirty mg/kg and 15 mg/kg Bdph were given daily through intraperitoneal injection for 4 weeks after laser treatment. Fluorescein angiography (FA) and choroidal flat mount were used to measure the development of CNV. Female New Zealand white rabbits' eyes were instilled with 10g/L Z,E-butylidenephthalide solution,and ocular blood flow was measured with colored microsphere technique. RESULTS: The intensity of fluorescein leakage, indicating the ocular lesion, decreased significantly in group Bdph 30mg/kg and 15mg/kg, as compared to the control at P<0.01.The area of neovascularization checked by FA in both groups of Bdph, at 30mg/kg and 15mg/kg decreased significantly compared to the control group at P<0.05. On the choroid flat mount, the areas of CNV were also smaller in both Bdph groups than in control group. One percent Z,E-butylidenephthalide solution instilled into rabbits' eyes could improve the choroid blood flow at 30 and 60 minutes after drug instillation (P<0.05).CONCLUSION: Z,E-butylidedephthalide could inhibit the development of CNV in the rat eyes and increase the choroid blood flow in the rabbit eyes. These results suggest that Z,E-butylidedephthalide may be a good agent for the treatment of age-related macular degeneration(ARMD).

Middle East respiratory syndrome coronavirus (MERS-CoV) has caused outbreaks of SARS-like disease with 35% case-fatality rate, mainly in the Middle East. A more severe outbreak of MERS occurred recently in the Republic of Korea, where 186 people contracted the infections, causing great concern worldwide. So far, there has been no clinically available drug for the treatment of MERS-CoV infection. The potential drugs against MERS-CoV mainly consist of monoclonal antibodies, peptides and small molecular agents. Small molecular agents have an advantage of easier synthesis, lower cost in production and relatively higher stability. There is better chance for those candidates to gain a quick development. This article reviews the progress of developing small molecular MERS-CoV agents.

In 2012, a new SARS-like coronavirus emerged in the Middle East, namely the Middle East respiratory syndrome coronavirus (MERS-CoV). It has caused outbreaks with high mortality. During infection of target cell, MERS-CoV S protein S1 subunit binds to the cellular receptor (DPP4), and its S2 subunit HR1 and HR2 regions intact with each other to form a stable six-helix bundle to mediate the fusion between virus and target cell membranes. Hence, blocking the process of six-helix bundle formation can effectively inhibit MERS-CoV entry into the target cells. This review focuses on the recent advance in the development of peptidic entry inhibitors targeting the MERS-CoV S2 subunit.
