The invention relates to a diabetic retinopathy fundus photography grading report system combined with a clinical guide, based on an artificial intelligence deep learning technology, and belongs to the field of fundus lesion analysis. The system accurately identifies and segments various lesions such as microhemangioma, bleeding, exudation and the like and symbolic structures such as optic discs, macular regions and the like by automatically analyzing fundus photographic images. The system adopts ICDR international standards to grade diabetic retinopathy, and provides diagnosis and treatment suggestions for lesion characteristics in combination with clinical guidelines of American ophthalmology institute in 2019. Through big data training, the system can generate detailed reports in real time, the early screening rate is remarkably improved, misdiagnosis and missed diagnosis are reduced, and the diagnosis speed and accuracy are improved. The system comprises a plurality of modules, such as an image pre-classification module, a deep learning focus recognition module, an ICDR grading module and a report generation module, efficient and accurate diabetic retinopathy diagnosis and grading are cooperatively achieved, and the clinical management level is improved.

Device: The invention aims to treat skin imperfections (spots, angiomas, freckles, marks, spots, discolorations, stretch marks, scars, etc.), to erase them, and to diminish their appearance. More and more people are experiencing problems with skin imperfections (spots, angiomas, freckles, marks, spots, discolorations, stretch marks, scars, etc.), and are particularly sensitive to what they consider a problem. This constitutes a real societal phenomenon. Many people are distressed by these visual aspects of their skin. It is therefore necessary to make these features invisible or less visible. The proposed technical solution is to use colored inks to create a skin tone match and to tattoo the area to be treated with this ink. [Fig. 1] A specific needle [Fig. 2] can be used for this procedure.

The present invention relates to a composition for inhibiting angiogenesis containing yohimbine, and more specifically, to a pharmaceutical preparation and a functional food containing a composition capable of exhibiting preventive, improving, and therapeutic effects on angiogenesis-related diseases such as hemangioma, vascular adhesion, neovascular glaucoma, diabetic retinopathy, macular degeneration, corneal disease caused by neovascularization, or telangiectasia by containing yohimbine capable of inhibiting PDGF-induced vascular smooth muscle cell proliferation and migration through the factor FOXO3a.

The invention relates to the technical field of medical image processing and disease auxiliary diagnosis, in particular to a diabetic neuropathy auxiliary detection system based on ophthalmologic images. According to the system, the fundus image acquisition module, the hysteresis analysis module, the region fusion module, the microhemangioma influence degree acquisition module and the diabetic neuropathy detection module are arranged to analyze gray change characteristics of pixel points in an FFA image, the hysteresis degree of the pixel points filled with fluorescein is acquired, region fusion is carried out according to the hysteresis degree, and the detection accuracy of the diabetic neuropathy is improved. And quantifying the influence degree of the microhemangioma according to the average lag degree of the fusion region and the region area to realize the judgment of the diabetic neuropathy. The system obtains the influence degree of the microhemangioma by quantitatively analyzing the filling and diffusion rules of fluorescein in the microhemangioma and the surrounding area of the microhemangioma, and achieves the auxiliary detection of the diabetic neuropathy, thereby assisting doctors to efficiently and accurately detect the diabetic neuropathy, and effectively improving the diagnosis efficiency and accuracy.

The utility model relates to a catheter capable of simultaneously completing hemangioma embolism and intraoperative radiography, which comprises a catheter main body, a contrast agent channel and an embolism channel which are mutually independent are arranged in the catheter main body, the contrast agent channel and the embolism channel penetrate through two ends of the catheter main body, and a connector is arranged at one end of the catheter main body. The connector is provided with a contrast agent inlet and an embolism material inlet, the contrast agent inlet is communicated with one end of the contrast agent channel, the embolism material inlet is communicated with one end of the embolism channel, and the catheter body is provided with a sealing structure used for sealing or opening the other end of the contrast agent channel. By means of the integrated design, seamless switching between embolism and radiography operation is achieved, the operation process is simplified, the operation time is shortened, the embolism effect is monitored through real-time radiography, it is ensured that the release position and number of embolism materials are accurate, the number of times of catheter insertion and replacement is reduced, vascular injury and intraoperative infection risks are reduced, use of various catheters and auxiliary equipment is reduced, and the operation efficiency is improved. The operation consumable cost is reduced, and the catheter is easy to operate and wide in application range.
