目的:用Verion智能导航系统观察坐位到卧位、飞秒激光负压吸引及吸引解除后的眼球旋转情况.方法:术前用Verion采集患者坐位眼前节图片,与术中采集的卧位眼前节图片进行比对,得到坐位至卧位眼球的第一次旋转,记录大小及方向.飞秒激光负压吸引术眼,以负压吸引后的眼前节图片与卧位图片进行比对,得到卧位至负压吸引后的眼球第二次旋转,记录大小及方向.完成飞秒相关步骤后,解除负压吸引,以此时的眼前节图片与坐
Objective: Recent studies showed that human lens epithelial cells (HLECs) are living in an environment of hypoxiain physiological condition.The oxygen level is only about 3~7mmHg (7.6mmHg=1% O2).Howev
For the management of obesity, a host of single therapies have been investigated and considered so far.However, when a particular pathway is blocked by a single therapy, the body starts to activate al
Gene silencing via RNA interference (RNAi) has been demonstrated as a great potential therapeutic agent for cancer treatment.The emerging RNAi therapy delivers gene-silencing RNAs to the cytoplasm whe
Knowledge-based medicine goes beyond current medical and pharmaceutical paradigms by integrating the broad spectrum of medical technology with the individualized view of a patient and his disease in a
Nanoparticles of various compositions and structures and with sizes below 150 nm are the subjects of intensive investigation for the effective intracellular delivery of diagnostics and therapeutics.
Our research interests focus on the study of cancer cell communications by microfluidics and the development of nanotechnology to detect and destruct cancer cells.Recent studies reveal that solid tumo
High-performance fluorescent materials for cancer targeting are highly desirable for biosensing and imaging in vivo.Here we report a unique molecular design strategy for tailoring the aggregation-indu
