Objective To apply E- learning in training of related knowledge about public health emergencies in emergency department in order to improve the treatment level of medical staff in public health emergencies. Methods The medical staff was divided into the observation group and the control group with 50 persons in each group according to the odd and even grouping method. The control group was given conventional training method, while the observation group received E- learning based on conventional training method. The theoretical test results and training effect were compared between two groups. Results The scores of the observation group were obviously higher than that of the control group [ (90.88 ± 4.09) points vs. (84.36± 4.92) points ], Z= -5.895, P<0.01. Conclusions The application of E- learning in the training of public health emergencies is beneficial to help the medical staff to obtain and share information resources more conveniently, to enhance the ability of the clinic medical workers of understanding the condition of emergent public health affairs, to elevate the grades of theoretical learning of the relevant knowledge and to improve the management level of training, training effect and efficiency.

The pathogenesis of brain injury in fetal growth restriction (FGR) fetuses is likely associated with oxidative stress and neuroinflammation, although the exact mechanisms are not fully understood. This article mainly reviews the anatomical alterations, potential pathophysiological processes, and the specific molecular mechanisms involving various types of brain cells in FGR.

Objective:To analyze the expression and clinical significance of serum retinol binding protein 4 (RBP4), superoxide dismutase (SOD) and hypersensitive C-reactive protein (hs-CRP) in patients with acute ST-segment elevated myocardial infarction (STEMI).Methods:Seventy-eight patients with STEMI who underwent percutaneous coronary intervention (PCI) admitted to Nanxishan Hospital of Guangxi Zhuang Autonomous Region from January 2017 to March 2019 were enrolled. On the basis of the routine treatment, atorvastatin calcium or rosuvastatin calcium treatment was given. According to the results of coronary angiography, the patients were divided into three groups: single-vessel, double-vessel and three-vessel lesions, and the severity of coronary artery disease score (SYNTAX score) was performed. The serum RBP4, SOD and hs-CRP were measured and compared among different groups before and after treatment. The correlation between the three serum parameters of STEMI patients and the SYNTAX score, risk prediction (STEMI high-risk score) and prognosis were recorded and compared among different groups.Results:There was no significant difference in serum RBP4, SOD and hs-CRP among different groups before treatment. In multivessel (double-vessel and three-vessel) vascular disease group, SYNTAX score was significantly correlated with RBP4 and hs-CRP (double-vessel lesions: r values were 0.616 and 0.489 respectively, three-vessel lesions: r values were 0.423 and 0.357 respectively, all P < 0.05), but had no correlation with SOD ( r values were 0.108 and 0.055 respectively, both P > 0.05), and high-risk score was closely correlated with RBP4 and hs-CRP levels ( r values were 0.581 and 0.623 respectively, both P < 0.01). There was no significant difference in the prognosis of patients treated with different statins. There were 8 and 7 high-risk patients in the atorvastatin calcium group and rosuvastatin calcium group, respectively, and 2 and 3 dead patients respectively (both P > 0.05). Conclusion:Combined detection of serum RBP4, SOD and hs-CRP levels can be used as better indicators to predict the risk of STEMI, which is worthy of clinical application.
