1.Injury patterns and risk factors of motorcycle crashes
Chinese Journal of Tissue Engineering Research 2006;10(40):187-190
OBJECTIVE: To investigate the injury patterns and risk factors of motorcycle crashes.DATA SOURCES: A computer-based online search was undertaken to identify English articles about motorcycle crashes published from January 1980 to December 2005 in Medline database and from January 1995 to December 2005 in EMCC database, the keywords were "motorcycle,crash, injury, traffic accident". Meanwhile, a manual search of relevant journals and monographs was performed for the articles and data published in Chinese.STUDY SELECTION: Based on the principles of reliability, advancement and efficiency, the data were primarily examined, and the original articles in this research field were selected to look up the full-texts. The repetitive studies and reviews were excluded.DATA EXTRACTION: Totally 87 articles were collected about the incidence, mechanism and protective methods of motorcycle crashes and motorcycle injuries, 36 of them were excluded, and finally 51 were enrolled.DATA SYNTHESIS: The most important variable affecting mortality in motorcycle crashes is head injury. Wearing a helmet should continue to be compulsory, as this single measure can help to reduce the mortality in motorcyclists. Thoracic and abdominal trauma as well as pelvic ring fractures associated with long bone injuries appears to be the secondary factors contributing to reduced survival. The injured motorcyclists were predominant young, novice inexperienced riders and male. A fatal outcome was more likely to be associated with a larger engine capacity motorcycle, collision with a heavy vehicle, head on collision, and collision at a non-junction road. Alcohol and excessive speed were common factors associated with motorcyclist crash involvement.CONCLUSION: Motorcycle crashes are an increasing public health problem in the present world. A thorough understanding of the injury patterns and risk factors in motorcyclists may improve the initial assessment and management of these patients and reduce the risk of inflicting further iatrogenic complications. Renewed and strengthened prevention efforts are warranted. A stricter enforcement of helmet laws would be effective to increase compliance with active protection devices. Stricter law enforcement also should be carried out to prevent alcohol-related accidents. It is hoped that these results will ultimately be used in concert with that from other researchers focusing on preventative devices to reduce the incidence of motorcycle crashes and still others examining specific therapies to address the type and nature of the motorcycle injury.
2.Progress on DAB2IP gene
Chinese Journal of Pathophysiology 2011;27(7):1445-1449
Human DAB2 interaction protein (DAB2IP) is a novel member of Ras GTPase-activating protein family. It interacts directly with disabled-2 protein (DAB2/DOC2) which suppresses growth of cancers derived from different tissues, including mammary, prostate and ovarian cancers. DAB2IP was identified as an immediate downstream effector mediated by DAB2/DOC2. DAB2IP and DAB2/DOC2 form a unique protein complex that has a negative regulatory effect on the Ras-mediated signal pathway. It is demonstrated that DAB2IP is a tumor suppressor gene inactivated by methylation in several cancers. This article reviews the structure and biological functions of DAB2IP gene as well as its potential roles in carcinogenesis and evolution.

4.China’s participation of global environment and health governance:Opportunities, challenges and policy recommendation
Chinese Journal of Health Policy 2015;(7):21-25
China faces opportunities and challenges as well when it participates in global environment and health governance. Major opportunities are as follows:(1) The convergence between global environment and health governance’s future trend and China’s environment and health strategies is a strongest incentive to push China to par-ticipate in global environment and health governance;(2) China can benefit from this participation in term of more access to international resources; ( 3 ) Global environmental and health issues are the areas that can best illustrate China’s international image as a responsible member; ( 4 ) Since global environmental and health governance is still young, early participation will give China a louder voice in its decision-making. The challenges that China faces are as follows:(1) Huge pressure from domestic environment and health challenges forces China to be primarily inward-looking and makes it very hard for the country to keep a high profile in global environment and health governance. China also faces the increasing international pressure. ( 2 ) The lack of global environment and health governance strategy prevents China from effectively participating in global environment and health governance. (3)“The Grand Health Outlook”hasn’t been fully established yet in China, leaving much room for improvement. (4) Intellectual sup-port is inadequate. (5) Some countries have too high expectations of China in terms of its contribution to global envi-ronmental and health governance. In order to effectively participate in this field, China should undertake coordinated planning on both the international and domestic scenes, and take some specific policies both at national and interna-tional level.

6.Application strategy of hemostatics in total knee arthroplasty
Journal of Clinical Surgery 2016;24(10):800-802
Bone and soft tissue bleeding often results in substantial amounts of blood loss during the total knee arthroplasty(TKA). Multiple studies have reported that cumulative blood loss varies from 500 to 1500 mL in primary settings. Increased perioperative blood loss frequently requires allogeneic blood transfusions to improve the hematocrit and hemoglobin levels. However,allogeneic transfusion is associated with risks of immunosuppression,transfusion reactions,graft versus host disease,and transmission of infec-tions. To avoid these problems and reduce costs of transfusion,multiple intraoperative pharmacotherapeutic strategies have been developed. The various pharmacotherapeutic agents currently used include tranexamic acid,epsilon-aminocaproic acid,fibrin,thrombin,lavage with epinephrine,and norepinephrine. However, the relative efficacy and the cost-effectiveness of these agents may vary. Thus,the purpose of this study was to provide a brief overview of the relative efficacy of various intraoperative pharmacological methods cur-rently in use for decreasing blood loss following TKA and describe their potential complications associated with their application.
