I have engaged in the research of rice stripe blight control for many years in Shanghai farm and found some problems: though there were some reports of research on rice stripe blight resistance, strategy of prevention and cure for the disease has been face to farmer mainly, while geographical location, cultivars and cultivation system adopted on the Farm all affect the effect of control. On the other hand, our Farm has paid attention to the chemical prevention and cure for rice stripe blight and ignored other measures. As for the chemical prevention and cure, phenomenon of drug-resistance and bad effect of prevention and cure existed usually.
本人在上海农场多年从事该课题研究过程中发现的问题:目前对水稻条纹叶枯病研究的报道较多,在防治对策上主要是针对农户,缺乏关于农场地域因素、品种、栽培制度等因素对水稻条纹叶枯病发生及防治的影响的报道;在水稻条纹叶枯病的防治上,农场仍是以化学防治为主,对其他防治措施还不够重视;在化学防治过程中,存在抗药性、防效不佳等问题。

Research background: Choroidal neovascularization is a common cause of vision loss in patients, which often resulted from exudative Age-related macular degeneration、 pathologic myopia、 central serous chorioretinopathy、ocular histoplasmosis and angioid streaks, Rarely, CNV is seen in children, usually in association with inherited macular dystrophies. Despite extensive basic and clinical research, our knowledge of the complicated molecular mechanism of CNV is still limited, for these reasons currently used therapeutic approaches are insufficiently effective.
课题研究背景:脉络膜新生血管(choroidal neovascularization,CNV)是导致视力丧失的一种常见原因,多继发于渗出型年龄相关性黄斑变性、近视性黄斑变性、中心性浆液性脉络膜视网膜炎、眼组织胞浆菌病和眼底血管样条纹等眼病,在儿童罕见,主要与遗传性黄斑营养不良有关,尽管近年来进行了大量的基础和临床研究,但对CNV复杂分子机制的认识仍然非常有限,因此目前的治疗措施都不尽如人意。
