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 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
