Preparation method and application of targeted co-supported drug delivery system nano-particles based on polylactic-co-glycolic acid

The invention relates to a preparation method and application of targeted co-supported drug delivery system nano-particles based on polylactic-co-glycolic acid (PLGA), which can effectively solve the problem of preparing the targeted co-supported drug delivery system nano-particles based on polylactic-co-glycolic acid, and realizes the application in cerebral tumor targeted treatment medicines. The method comprises the following steps: connecting Angiopep-2 by utilizing the reactive amino group on chitosan: reacting chitosan with 3-maleimidopropionic acid N-hydroxysuccinimide to enable the amino terminal of chitosan to have maleimide; reacting with terminal-sulfhydrylated Angiopepe-2 to obtain a chitosan-angiopep-2 polymer. The polymer can be applied to preparation of a PLGA-based targeted co-supported drug delivery system. The method is stable and reliable, the product has a good using effect, small-molecular chemical drugs and genetic drugs can be delivered at the same time, or a fluorescent probe can pass through a blood brain barrier and enters the brain while chemotherapeutic drugs are delivered, and targeted cerebral tumor treatment can be synergized or targeted cerebral tumor treatment and diagnosis can be integrated into a whole.

Injection of mannite and glycerol and preparation method thereof

The invention discloses injection of mannite and glycerol, which contains mannite, glycerol and water for injection. Furthermore, the invention also discloses a method for preparing the injection, which comprises the following steps: taking the mannite and the glycerol, dissolving into the water for injection, filtering and filling. The injection of the mannite and the glycerol is clinically used for treating cerebrovascular diseases, brain trauma, cerebral tumors, intracranial inflammation and the diseases of acute and chronic intracranial hypertension, hydrocephalus and the like caused by other reasons. The injection of the mannite and the glycerol has the functions of lowering the intracranial pressure quickly and eliminating the hydrocephalus and can also avoid death because of acute renal failure caused by the injury of the kidney; the injection of the mannite and the glycerol suppresses the apoptosis of neural cells and achieves the function of protecting the brain; the function of lowering the intracranial pressure is stable and has long retention time; crystals occurring because of the change of the air temperature or in the processes of storage and transportation are eliminated; and the glycerol is used as a caloric agent and can improve and recover the energy metabolism of the important viscera of the heart, the brain, the kidney and the like during oxygen deficiency. The injection of the mannite and the glycerol is a very effective, stable and safe medicine for promoting urination and removing water clinically.

Full-connection CRF cascaded FCN and K mean value brain tumor segmentation algorithm

The invention relates to a brain tumor segmentation algorithm based on combination of deep learning and a traditional segmentation algorithm, in particular to a full-connection CRF cascaded FCN and Kmean value brain tumor segmentation algorithm. The DenseCRF matches all the pixels in the original image with each pixel in the segmentation result of the FCN algorithm, finds the pixels with the sameattribute, supplementarily smoothes the input, improves the detail information of the segmentation result, and improves the segmentation precision. Meanwhile, in different segmentation algorithms, the segmentation standards are different, and the segmentation results obtained based on the algorithms of the different segmentation standards are complementary to each other by fusing the deep learning algorithm FCN with the different segmentation standards and the traditional segmentation algorithm K-means clustering, so that the segmentation results are closer to real segmentation images. Therefore, the brain tumor nuclear magnetic resonance image is segmented more accurately, and a more accurate tumor image is provided for high-precision repetitive measurement and evaluation of the brain tumor nuclear magnetic resonance image.

MRI (Magnetic Resonance Imaging) image segmentation method based on fuzzy thought and level set frame

ActiveCN106127734AOvercoming the phenomenon of difficulty in part segmentation convergenceAccurate target outlineImage enhancementImage analysisNMR - Nuclear magnetic resonanceCancer cell
The invention discloses a MRI (Magnetic Resonance Imaging) image segmentation method based on fuzzy thought and a level set frame, and mainly solves the problem of segmentation errors and low calculation speed generated since an original segmentation method can not overcome an intensity non-uniformity phenomenon or noise interference in the MRI process that the nuclear magnetic resonance image is segmented. The method comprises the following implementation steps: 1) inputting an original nuclear magnetic resonance image; 2) carrying out iterative computation on a magnetic resonance image matrix to solve a membership matrix u corresponding to a magnetic resonance image matrix I; 3) regulating an evolution propulsive parameter, and guaranteeing that the membership matrix u is subjected to exact convergence on a target outline; and 4) representing different areas in the image matrix I with different element values of the membership matrix u to obtain an anticipatory segmentation result. By use of the method, the segmentation process of the nuclear magnetic resonance image can be effectively and quickly finished, an accurate target area can be obtained, and the method can be used for cerebral tumor detection and cancer cell examination in a MRI medical image.
