In recent years, he has mainly devoted himself to the research on new techniques of coronary intervention and stent restenosis. 1999 took the lead in developing percutaneous intracoronary cutting balloon angioplasty technology in China, and the article "Clinical evaluation of 44 cases of cutting balloon angioplasty" won the first prize of excellent papers in the 4th National Heart Intervention Forum. In 2000, percutaneous coronary intervention was performed through upper limbs. 200 1 To summarize the clinical effect of unprotected selective stent implantation for left main artery disease, and his article "Unprotected selective stent implantation for left main artery disease" was published in chinese journal of cardiology and won the third prize of Beijing Science and Technology Progress Award.

In 2002, the clinical study of dexamethasone coated stent in the treatment of coronary small vessel diseases was carried out for the first time in China. From 2003 to 2008, the first registered study of acute coronary syndrome with the largest sample size and a clinical follow-up of 7 years was conducted in China, and the data of the treatment status of acute coronary syndrome in China were obtained. A series of studies were conducted on no-reflow phenomenon after myocardial infarction reperfusion therapy, and the mechanism of no-reflow was discussed. Published more than 30 papers/kloc-0 (38 in chinese magazine and 9 in sci), with a total impact factor of more than 15. There are 5 chief editors (ranked 13, 22nd) and 8 chief editors.

In recent years, we have devoted ourselves to the early diagnosis and treatment of coronary heart disease, and carried out new imaging technologies such as intravascular ultrasound, optical coherence tomography and coronary CT to guide the diagnosis and treatment of coronary heart disease, and achieved initial results. In the interventional therapy of coronary heart disease, we are committed to the research and development and clinical evaluation of new devices, among which the research of a new drug-eluting composite stent for capturing endothelial progenitor cells is supported by the 863 project of the Ministry of Science and Technology.
