简介：AbstractAn increasing body of evidence supports the hypothesis that atherosclerosis is caused by multiple factors and mechanisms. A better understanding of the contribution of hypertriglyceridemia or oleic acid to the pathogenesis of atherosclerosis would significantly increase our ability to successfully treat these diseases. We propose that oleic acid promotes atherosclerosis via multiple pathophysiological mechanisms. Here we suggest that (1) atherosclerosis may develop through multiple pathophysiological mechanisms and that this may be a common feature of human diseases; (2) diseases may be the consequence of natural selection or the interaction of internal and external factors; (3) diseases should be recognized with "biological diversity," and that this concept should be introduced into medical education, clinical treatment, drug research and development, and medical research. The work reported here will benefit a new generation of medical trainees and promote the development of the relevant medical fields.

简介：AbstractTranexamic acid (TXA) is an anti-fibrinolytic agent which has been proven beneficial in multiple surgical specialties where significant bleeding can occur. Whilst it has been widely available for over 40 years its use within Otorhinolaryngology is still limited. Operations in Otorhinolaryngology are particularly varied with some such as tonsillectomy having the potential for significant life threatening bleeding. Other operations are performed within small confined surgical fields and even small amounts of bleeding can significantly detriment surgical field and increase technical difficulty and operative time. This review evaluated the current literature on the benefits of tranexamic acid within the field of Otorhinolaryngology and Head and Neck Surgery. Overall TXA was demonstrated to be a safe drug with no major adverse effects including thromboembolic events reported in any study. It has been shown to be of particular benefit in rhinology by improving surgical field, reducing operative time and reducing postoperative swelling and ecchymosis. The benefit in tonsillectomy is less clear and further studies are required to evaluate its potential use in the reduction of post tonsillectomy haemorrhage rates.
