RESUMEN
BACKGROUND:Concussions caused by contact sports or traffic accidents are far more serious and common than people think,and have attracted widespread attention and high attention from the media,medical and sports circles in recent years. OBJECTIVE:To visualize the hot spots and trends in the field of concussion by using the method of bibliometrics,so as to provide some reference for the research in this field in China. METHODS:Based on the core collection database of Web of Science,the keyword retrieval strategy was(TS=(Concussion))AND TS=(Finite element).CiteSpace 6.2.R4 visualization tool was used to visually analyze the author,country,institution,keywords,cited documents,etc. RESULTS AND CONCLUSION:A total of 215 articles were included,with a general upward trend in the number of publications and citations.The distribution of disciplines involves biomedical engineering,biophysics,sports science,clinical neurology,neuroscience and other disciplines,showing a trend of interdisciplinary integration.The author with the most publications is Gilchrist M from University College Dublin,Ireland,the institution with the most publications is the University of Ottawa,and the country with the most publications is the United States.Key word analysis shows that the focus of research is on the establishment of brain injury models to simulate and predict concussion injuries;analysis of concussion injury mechanism;optimal design of protective equipment and devices.Through literature co-citation analysis,it is found that the prediction and evaluation of brain injury is the knowledge base and research hotspot in this field.The research hotspot of finite element application in the field of concussion injury mainly focuses on the prediction of head injury,combined with the exploration of brain injury mechanism and the design and improvement of protective equipment.With the progress of artificial intelligence and materials science,future research hotspots in the field of concussion injury will focus on the improvement of brain injury models,test methods and protective equipment.

Objective:To explore the related factors of epilepsy secondary to aneurysmal subarachnoid hemorrhage in the elderly.Methods:From January 2015 to January 2019, 213 elderly patients with aneurysmal subarachnoid hemorrhage admitted to Wuhan Hospital of Traditional Chinese Medicine were divided into epilepsy group(46 cases) and non-epilepsy group(167 cases) according to whether secondary epilepsy.Univariate analysis was used to analyze the related factors affecting epilepsy secondary to aneurysmal subarachnoid hemorrhage in the elderly, and multivariate logistic regression was used to analyze the risk factors of epilepsy secondary to aneurysmal subarachnoid hemorrhage in the elderly.The investigation factors included sex, age, hypertension, diabetes mellitus, smoking history, location of responsible aneurysms, number of aneurysms, intracranial hematoma, hydrocephalus and neurological sequelae.Results:Univariate analysis showed that there were no statistically significant differences in sex, age, history of diabetes mellitus and smoking between the two groups(all P>0.05). There were statistically significant differences between the epilepsy group and non epilepsy group in hypertension(15 cases vs.22 cases), location of responsible aneurysms in middle cerebral artery(22 cases vs.24 cases), number of aneurysms(23 cases vs.41 cases), intracranial hematoma(15 cases vs.26 cases), hydrocephalus(15 cases vs.21 cases) and neurological sequelae(14 cases vs.20 cases)(χ 2=9.491, 23.840, 11.113, 6.737, 10.306, 9.161, all P<0.05). The results of multivariate analysis showed that hypertension, middle cerebral artery, multiple aneurysms, intracranial hematoma, hydrocephalus and neurologic sequelae were risk factors for epilepsy secondary to aneurysmal subarachnoid hemorrhage in the elderly[ OR(95% CI)2.361(1.476-3.421), 3.012(1.935-1.845), 1.494(1.027-1.845), 2.785(1.684-3.982), 1.920(1.283-2.984), 1.637(1.171-2.316)]. Conclusion:There are many factors influencing secondary epilepsy in elderly patients with aneurysmal subarachnoid hemorrhage.In order to reduce the incidence of secondary epilepsy, preventive measures should be taken against the above risk factors.
RESUMEN
BACKGROUND: Ankle fracture combined with deltoid ligament rupture and distal tibiofibular syndesmosis injury occurs occasionally. Its treatment with distal tibiofibular syndesmosis screw fixation or deltoid ligament repair remains controversial. The former appears with poor reduction, broken nails, secondary surgery and other problems.OBJECTIVE: To observe the clinical effectiveness of suture anchor repair for ankle fracture combined with deltoid ligament injury.METHODS: Twelve patients with ankle fracture combined with deltoid ligament injury were selected from the First Affiliated Hospital of Guangzhou University of Chinese Medicine between January 2013 and December 2015. All patients were treated with open reduction, internal fixation, and anchor repair, but without distal tibiofibular syndesmosis screw fixation. The curative efficacy and joint stability were observed.RESULTS AND CONCLUSION: (1) All patients were followed-up for more than 12 months. (2) The modified Baird-Jackson scoring system showed excellent in nine cases, good in two cases, average in one case, poor in none case, and the excellent and good rate was 92%. (3) At 1 year after internal fixation, the X-ray examination showed the malleolus gap and talus slope angle of the affect side were (3.47±0.12) mm and (0.45±0.18)°, and the malleolus gap and talus slope angle of the healthy side were (3.44±0.05) mm and (0.43±0.14)°, and there was no significant difference between two sides (P > 0.05). (4) These results indicate that the suture anchor can repair the anatomy and biomechanics of deltoid ligament with stable ankle joint, and secondary surgery is unnecessary.
RESUMEN
Objective To investigate the clinic signification of newborn hearing screening combined with deafness susceptibility genes screening. Methods 1 440 newborns(3 ~ 5 days after birth) were screened for 8 hot spot hearing loss associated mutations from GJB2, mt12S rRNA and SLC26A4. At the same time, all infants received hearing screening. Those who failed to pass two-step test were referred to further audiological assessment. Results The carrier rate of commonmutations was 1.46% for GJB2 c.235delC, 0.35% for GJB2 c.299-300delAT, 0.42% for mt12S rRNA c.1555A > G, 0.42% for SLC26A4 c.IVS7-2A > G and 0.14% for SLC26A4 c.2168A > G. The total carrier rate was 2.78%. 10 infants were diagnosed as hearing loss in the hearing screening and follow-up audiology assessment (6.94‰) and 5 were diagnosed as severe hearing loss (3.47‰). 32 hearing loss associated mutation carriers passed the hearing screening. Conclusions Genetic screening of newborn hearing screening can be helpful to find out neonates with late-onset and progressive hearing impairment, which were significant for early intervention, regular follow-up and reduction of deafness.
