1.Biodegradable and non-biodegradable drug-eluting stents and bare metal stents in acute myocardial infarction
Chinese Journal of Tissue Engineering Research 2014;(34):5449-5454
BACKGROUND:Large randomized controled clinical trials have shown that drug-eluting stents has a lower
restenosis rate compared with bare-metal stents, but the drug-eluting stents cannot reduce major cardiovascular events and death rates, and long-term folow-up of clinical registries show the drug-eluting stents even may
increase late stent thrombosis events.
OBJECTIVE:To evaluate the incidence of stenosis and adverse reactions after treatment with biodegradable, non-biodegradable drug-eluting stents and bare-metal stents in patients after myocardial infarction.
METHODS:We retrospectively analyzed the clinical data of 236 cases of acute myocardial infarction, in which 79 cases were treated with biodegradable sirolimus-eluting stents, 83 cases treated with non-biodegradable
sirolimus-eluting stents, and 74 cases treated with bare metal stents. Then, we compared late lumen loss and restenosis within 12 months after stent implantation and major adverse cardiac reactions within 24 months after stent implantation.
RESULTS AND CONCLUSION: After 12 months, the late lumen loss of the bare stent group was significantly higher than that of biodegradable and non-biodegradable sirolimus-eluting stent groups (P < 0.05), but the
difference in stent restenosis rate (P > 0.05). After 24 months, there were no differences in death, cardiac death, recurrent myocardial infarction, target vessel revascularization, target lesion revascularization, major adverse
cardiac events and stent thrombosis events among the three groups. These three kinds of stents need to be
further studied in their long-term efficacy and safety as percutaneous coronary intervention for acute ST-segment elevation myocardial infarction.

4.Diagnosis and repair of chronic ankle instability
Chinese Journal of Tissue Engineering Research 2014;(9):1434-1440
BACKGROUND:Chronic ankle instability affects normal life severely. Therefore, chronic ankle instability causes more and more attention of experts, and choice of reasonable and effective diagnosis and targeted treatment method for chronic ankle instability in early stage has become an important issue in the clinic.
OBJECTIVE:To review literature research on the diagnosis and treatment of chronic ankle instability in recent years, and to provide reference and evaluation criteria for the diagnosis and reasonable and effective treatment of chronic ankle instability in clinical practice.
METHODS:We searched PubMed database, China National Knowledge Infrastructure, Wanfang database and VIP database for clinical and basic experimental research on chronic ankle instability. Keywords were“chronic ankle, instability, diagnosis, rehabilitation exercises, surgery methods, research progress”in Chinese and“chronic ankle, instability, diagnosis, rehabilitation exercises, surgical methods, research”in English. Total y 40 literatures were analyzed.
RESULTS AND CONCLUSION:Because of the special anatomical features and biomechanical advantages of the ankle, we should first consider the early diagnosis and effective treatment in chronic ankle instability patients. The treatment should focus on the anatomic characteristics, biomechanic characteristics, etiology of chronic ankle and diagnostic methods of the ankle joint. Conservative treatment and rehabilitation exercises after surgery play a major role in the recovery of chronic ankle instability. The use of balance board, tilting board, and climbing machines is an effective rehabilitation exercises for chronic ankle instability. The application of AOFOS-hind foot and ankle fibula reaction time is important for the assessment of functional recovery of the ankle joint. The emergence of arthroscope is an important clinical research direction of ankle surgery. This plays a significant effect on the treatment of chronic ankle instability.
