From March, 20065438 to March, 2002, I worked in xuanwu hospital Neuroradiology Training Center for Neurosurgery Intervention in Capital Medical University for one year. Under the guidance of Professor Ling Feng, a famous neurosurgeon in China, I mainly focused on interventional neuroradiology and microsurgery, and was awarded the title of "excellent student". After returning to the hospital in March, 2003, I actively participated in new topics and new operations carried out by the department, such as: the application of mild hypothermia treatment for critically ill patients in neurosurgery; Anterior cervical surgery for cervical disc herniation: application of single-door laminotomy in cervical spinal canal surgery: resection of giant trigeminal neurilemmoma through petrous approach: transsphenoidal pituitary adenoma resection; Modified pterional approach for severe craniocerebral injury complicated with cerebral hernia: intracranial aneurysm clipping: dural arteriovenous fistula clipping; Cerebral arteriovenous malformation surgery; Surgical treatment of hypertensive hemorrhage: the tumor was removed in front of the superior and inferior slopes and the foramen magnum; Resection of meningioma of anterior cranial fossa, sphenoid ridge and cerebellopontine angle in olfactory groove area; Resection of tumors in the posterior part of the third ventricle and pineal region; Brain stem tumor resection, and independent interventional neuroradiotherapy, such as: intracranial aneurysm embolization, cerebral arteriovenous malformation embolization, dural arteriovenous fistula embolization, spinal vascular malformation embolization, vascular tumor preoperative embolization, ultra-early thrombolysis for cerebral infarction, super-selective intra-arterial infusion chemotherapy for glioma, etc. Among them, embolization of spinal vascular malformation, embolization of dural arteriovenous malformation, superselective intra-arterial infusion chemotherapy of glioma and embolization of intracranial aneurysm occupy the leading position in the province, and more than 600 cases of interventional neuroradiotherapy have been carried out. He has written academic papers 16 and published them. He has joined the tutor group of master students and doctoral students majoring in neurosurgery in Kunming Medical College, and has undertaken the teaching of the second clinical department of Kunming Medical College, Haiyuan College and Adult Education College, as well as the teaching of master students, attending doctors, residents, rotation doctors and advanced doctors. He also participated in the consultation of difficult cases of neurosurgery in hospitals and prefecture-level hospitals, actively undertook the "health education" activities organized by hospitals, and taught a series of topics such as "prevention and treatment of hemorrhagic cerebrovascular disease and ischemic cerebrovascular disease", which was well received. Actively participate in various scientific research work in the department, participate in the key scientific and technological research project of the Ministry of Education, "Experimental study on the treatment of severe craniocerebral injury with deep hypothermia and no blood circulation", the project of Yunnan Natural Science Foundation, "Preparation of experimental model of selective deep hypothermia in monkey brain resuscitation", and the key project of Yunnan Natural Science Foundation, "Related research on electrophysiological and neurobiological changes of monkey brain with selective ultra-deep hypothermia", Undertaking the Tenth Five-Year Scientific and Technological Key Project of the Ministry of Health: "Study on the Application and Popularization of Standardized Surgical Treatment Technology for Stroke [2001Ba703b16 (b)]", which was well received by the research group. He undertook the key project of the Tenth Five-Year Plan of the Ministry of Science and Technology: "Cerebrovascular Disease Research (2004BA7 14B06- 1)" and was the project leader of Yunnan Province. In July, 2007, he was appointed as the executive director by the Professional Committee of Cardiovascular and Cerebrovascular Diseases of China Gerontology Society. In September 2007, he was hired as a member of the Neurointerventional Professional Group of the Fourth Committee of the Neurosurgery Branch of the Chinese Medical Association. In 2002, he was awarded the title of "Excellent Teacher of Kunming Medical College".
