Objective: To investigate the epidemiology of trauma patients in subtropical areas of Hainan Province and the improvement of the level of trauma treatment in China trauma care training (CTCT). Methods: From 01-01-2015 to 01-01-2016, the epidemiological data of 2476 patients with trauma were collected. From 01-01-2016 to 01-01-2017, 105 professional doctors and nurses in emergency surgery took part in CTCT, and their knowledge were compared before and after training. Results: There were 1656 male and 820 female trauma patients with 1614 cases in the middle and young age and 478 cases were the elderly. In terms of occupational distribution, 736 peasants, 574 workers and 458 retirees were involved. In May, the number of patients was the highest 332. October to January was the high-incidence season of trauma. In 24 hours a day: 11:00-13:00, 18:00-19:00, 23:00-03:00 were the high incidence periods. Referred to trauma sites, 904 cases of trauma happened on roads, 540 cases in family and 370 cases in restaurants or entertainment facilities. Through CTCT, the scores of the theoretical examination, the assessment of the trauma treatment skills and the field test scores of the emergency surgery practitioners were better than before (P<0.05).The misdiagnosis rate of severe trauma patients decreased from 26.21% to 15.36% (P<0.05). The mortality rate of severe trauma patients decreased from 18.67% to 13.94% (P<0.05). Conclusions:Trauma epidemiology in Hainan is closely related to its special geographical environment, which provides a reference for the prevention and treatment of trauma in Hainan, and some information for the government to formulate corresponding laws and regulations, as well as emergency plans and other relevant strategies. CTCT training improves the level of theoretical knowledge and first aid skills of medical personnel involved in trauma treatment. Health departments and medical education departments may consider extending CTCT training and continuing education programs to Hainan and other parts of China.

Research Progress on the Role of miRNA-448 in Tumor

MicroRNA (miRNA) is a class of endogenous non-coding and regulatory single stranded small RNA molecules, about 18 - 24 nucleotides in length. More than 800 miRNA coding genes have been identified in the human genome, and about 113 target genes are predicted to be regulated, which distinguishes it from most oligonucleotides and functional RNA degraded fragments. It is involved in the regulation of cell proliferation, differentiation, apoptosis and other cell activities. At the same time, it is abnormal in liver cancer, breast cancer, glioma and other tumors, becoming a new biomarker, and participating in cancer differentiation, invasion and metastasis through the interaction with multiple target genes, such as SATB1, NF-KB and 5-HT2B. Mir-448 is abnormally expressed in a variety of tumor cells, such as liver cancer and non-small cell lung cancer. mirNA-448 may play a very important role in tumors. In order to deepen the understanding of the role of mirNA-448 in tumors, this paper reviews the research progress of the role of mirNA-448 in tumors.
