OBJECTIVETo understand the epidemiological characteristics of head injuries in children.

METHODSData was derived from the Chinese National Injury Surveillance System (NISS) in 2014. Method on descriptive analysis was applied to depict general information, injuries events and clinical characteristics of head injuries among children under 18 years of age.

RESULTSA total number of 47 690 cases with child head injuries in 2014 were collected, including 32 542 males and 15 148 females. 43.47% of them were under 1-4 years of age. In October, 06:00 PM appeared the peak time for the injuries to happen. The three leading causes responsible for child head injuries were falls (69.57%), hit by blunt force (14.23%) or road traffic (11.01%). Main locations responsible for the head injuries to happen were:at home (44.98%), at public places (19.65%) or on roads/streets (15.81%). Recreation activates (77.88%), driving (7.32%), sports (5.72%) were the three major activities causing the injuries to take place. Majority of the cases happened unintentionally (95.35%), with bruise (71.69%) or mild injuries (85.27%) and went back home after treatment (90.25%).

CONCLUSIONSIn 2014, child head injuries were seen more in males than in females and mostly occured at home. The leading causes for head injuries would include falls, hit by blunt stuff or road traffic .

Objective To comprehensively analyze the disease burden of drowning in the Chinese population both at the national and provincial levels in 1990 and 2013,to provide reference for the development of strategies regarding drowning prevention.Methods Both methods related to unified measurement framework and standardized estimation on Global Burden of Disease in 2013,were used.Data on deaths caused by injuries were from the following sources which include:Disease Surveillance Points,the National Maternal and Child Health Surveillance Network,the Death Registration Reporting System of Chinese Center for Disease Control and Prevention,Death Registration System and death information from Macau and Hong Kong areas of China.Injury-related incidence data was from the National Injury Surveillance System and literature review.Parameters as death/death rate,years of life lost due to premature mortality (YLL)/standardized YLL rate,years living with disability (YLD)/standardized YLD rate and disability-adjusted of life years (DALY)/standardized DALY were used to analyze the disease burden and changing trend on drowning at both the national and all the provincial levels.Results In 2013,the number of deaths due to drowning was 63 619 in China,with the standardized mortality rate as 5.29 per 100 000,accounting for 8.0％ of the total injury deaths.Drowning was the fourth leading cause of injury death in the whole population and the first leading cause of injury death among children aged ＜ 5 and 5-14 years old in 2013,with YLL of drowning as 3.49 million person years,YLD as 0.04 million person years,and DALY as 3.53 million person years.Compared with data from 1990,the rates on standardized mortality,standardized YLL,standardized YLD and standardized DALY of drowning all declined in 2013.The five provinces/districts/cities with the highest rates of drowning were Xinjiang (10.08 per 100 000),Jiangxi (8.44 per 100 000),Anhui (7.92 per 100 000),Guizhou (7.77 per 100 000) and Sichuan (7.68 per 100 000).Standardized mortality of drowning reduced in all provinces in 2013.Conclusions Disease burden of drowning in the Chinese population,especially in children,declined significantly in 2013,comparing to 1990.However,drowning remains a serious proble,with children and males in particular,in China.Research regarding prevention on drowning is in great need in the western and central areas where drowning mortalities appeared high.

Objective:To investigate whether SKA1 is a key molecule regulating malignant proliferation of liver cancer, and further explore its mechanism to provide molecular theoretical basis for subsequent targeted therapy.Methods:The data of liver cancer from TCGA database were analyzed by bioinformatics technology. The expression of SKA1 in liver cancer was analyzed. At the same time, we also analyzed the relationship between the expression of SKA1 and the prognosis of patients with liver cancer. The hepatoma cell line overexpressing SKA1 was constructed by liposome-mediated cell transfection technique, and the effect of SKA1 on the proliferation of hepatoma cells was further tested by CCK-8 and plate cloning assay. At the same time, we found that E2F1 is also highly expressed in liver cancer, using bioinformatics technology to analyze the correlation between SKA1 and E2F1 expression, further detecting the binding site of E2F1 in the SKA1 promoter region, and using dual luciferase technology to detect E2F1 against SKA1. Transcriptional activation.Results:KA1 was highly expressed in liver cancer tissues, and the overall survival rate of liver cancer patients with high SKA1 expression was 49.8%, lower than that of patients with low SKA1 expression, showing a negative correlation. E2F1 is also highly expressed in liver cancer tissues, and the survival time of patients with liver cancer with high E2F1 expression is significantly lower than that in the low expression group, which was negatively correlated with poor prognosis. SKA1 overexpression could increase the proliferation ability of liver cancer cells by nearly 50%. SKA1 is regulated by the E2F1 transcription factor, and the E2F1 transcription factor is combined with the SKA1 promoter to transcriptionally activate the expression of SKA1 in liver cancer cells.Conclusion:E2F1 transcriptional activation of SKA1 promotes proliferation of hepatoma cells, leading to poor prognosis in patients with liver cancer

Objective To understand the factors related with child restraint system (CRS) use,and provide evidence for the development of appropriate intervention measures to promote the use of CRS for the protection of child passengers' safety.Methods Self-administrated questionnaire survey was conducted among 0-6 years old children' s parents who owned private cars selected through stratified cluster random sampling in Shanghai and Shenzhen to collect date about CRS use and related factors.Group discussion was conducted among some of the parents randomly selected to further understand the reasons for using or not using CRS.Results Of 7 528 parents surveyed,39.23 ％ (2 820/7 189) reported to have CRS and 17.14％(1 232/7 189) reported consistent use of CRS.Multivariate analysis indicated that young age of children,high level of education of parents,good family economic status,awareness of importance of children's safety were the positive factors for CRS use.The frequency and distance of children' car taking and the seatbelt use of drivers significantly influenced the CRS use.The main reasons for not purchasing CRS included limited car space (53.33％,2 329/4 367),low frequency of children car taking (48.55％,2 120/4 367),difficulty in installation (42.25％,1 845/4 367),high cost (38.58％,1 685/4 367),and unreliable quality (31.03％,1 355/4 367).The main reasons for not using CRS included children' s refusal (67.36％,293/435),short travel distance (53.79％,234/435),difficulty in installation or use (53.10％,231/435),limited car space (32.41％,141/435),and unnecessary (25.75％,112/435).Conclusions Parents have gaps and misunderstandings in using CRSs to protect child passengers safety.There are demands of technical guiding service in use of CRS.Integrated intervention measures should be implemented targeting at the identified barriers and needs in CRS use to promote child passenger safety,which include strengthening the propaganda and education,promoting the legislation and law enforcement,strengthening market supervision,establishing CRS related services site,exploring the rental market,etc.
