Encephaledema segmentation method and system based on support vector machine algorithm

The invention provides an encephaledema segmentation method and system based on a support vector machine algorithm, which are applied to the medical diagnosis technology field. The encephaledema segmentation method comprises steps of using a plurality of CT images and a plurality of magnetic resonance T2 weighted images of patients suffering from first type hemorrhagic cerebral apoplexy to train a classifier based on the support vector machine algorithm, using the classifier to perform encephaledema segmentation on CT images of patients suffering from the second type hemorrhagic cerebral apoplexy, wherein the patients suffering from the first type hemorrhagic cerebral apoplexy have the CT images and the magnetic resonance T2 weighted images; and the patients suffering from the second type hemorrhagic cerebral apoplexy only have the CT images and do not have the magnetic resonance T2 weighted images. The invention utilizes few patients suffering from the hemorrhagic cerebral apoplexy having the CT images and the magnetic resonance T2 images to perform combined modeling, through studying, establishes a classifier which can identify the encephaledema on the CT from the CT image characteristics, can be applied to the patients who suffer from the hemorrhagic cerebral apoplexy and have the CT images and have no magnetic resonance T2 weighted images, and obtains the higher encephaledema segmentation accuracy.

Uses of Petasites tricholobus franch extract in medicament preparation for preventing and controlling cardiovascular and cerebrovascular diseases

ActiveCN101297828APharmacologically activeHave cardio-cerebrovascular pharmacological activityOrganic active ingredientsOrganic chemistryDiseaseReperfusion injury
The invention relates to the field of medical technology, which discloses a new usage of a petasites tricholobus franch extract and the contained bakkenolide compound in the preparation of drugs for prevention and treatment for cardiovascular and cerebrovascular diseases. The biological activity tests show that, the petasites tricholobus franch extract and the contained bakkenolide compound can significantly reduce the encephalic necrosis percentage of the rats with local cerebral ischemia, improve the behavior score of the ischemic rats and alleviate volume of brain edema and cerebral infarction of the rats with ischemia reperfusion injury, thus prompting that the petasites tricholobus franch extract and the contained bakkenolide compound have significant protective effect on the cerebral ischemia injury. The petasites tricholobus franch extract and the contained bakkenolide compound can further significantly reduce the J-point displacement caused by ISO and the LDH level in plasma, significantly reduce the scope of myocardial ischemic myocardial infarction of the rats caused by coronary artery ligation and lower the LDH level in the plasma of the rats with the myocardial ischemia. As the petasites tricholobus franch extract and the contained bakkenolide compound have good effects on the prevention and the treatment for heart and brain ischemic diseases aspects, the petasitestricholobus franch extract and the contained bakkenolide compound can be used in the preparation of drugs for prevention and treatment for cardiovascular and cerebrovascular diseases, including coronary heart disease, cerebral ischemia, cerebral infarction (stroke), myocardial infarction and so on.

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.
