Objective Hyperglycaemia and hyperlipid are common in clinical cardiovascular disease .The article was to ob-serve the change of endothelial and the expression of Rho-kinase in the aorta of rats with hyperglycaemia and hyperlipid and the rela-tionship between them .Methods Healthy male Wistar rats were randomly divided into 3 groups:5 as normal control group , 10 as model group and 10 as drug intervention group .The latter two groups were given high-fat diets for 5 weeks after tail vein injection of streptozocin (STZ) to establish hyperglycaemia and hyperlipid models , then fasudil (inhibitor of Rho-kinases) or saline were respec-tively given intraperitoneally for 4 weeks.Venous blood glucose (VBG), blood lipid levels, ET-1 and eNOS were tested, along with the expression of MYPT-1(the protein substrates of ROCK)、mRNA of RhoA and ROCK. Results Compared with normal control group, the levels of VBG、ET-1、MYPT-1、mRNA of ROCK and Rho A were increased in model group[(6.18±1.14)mmol/L vs (26.36± 3.25)mmol/L,(72.13±6.13 )pg/mL vs (88.22±4.61) pg/mL, (0.54±0.08) v s (1.28±0.17),(0.16±0.20) vs (0.83± 0.12),(0.40±0.18) vs (0.78±0.13),P<0.05].TG、TC、LDL were also higher in model group(P<0.05), while eNOS level was lower in model group than in control group[(24.42±2.13)U/L sv (17.36±1.58)U/L,P<0.05].Compared with model group, the levels of VBG[(17.70±2.69)mmol/L]、TG、TC、LDL, ET-1 [(75.03±2.50)pg/mL]、MYPT-1(0.74±0.01)、mRNA of ROCK(04.0±0.08) and Rho A (0.25±0.07)in drug intervention group were lower(P<0.05), while eNOS level (0.74±0.11) was higher(P<0.05) in drug intervention group than in model group . Conclusion Endothelial dysfunction and over-expression of Rho kinase can be found in hyperglycaemia and hyperlipid rat models .Fa-sudil could improve endothelial function .

The application of electronic informed consent has the advantages of speeding up the recruitment of subjects, helping the less educated to understand research and recruit groups, facilitating direct communication between subjects and researchers, minimizing human omissions and errors, and effectively improving the efficiency of clinical research. However, there are also some challenges, such as privacy, ethical censorship, hardware costs and so on. On the basis of the above discussion, this paper believed that electronic informed consent, as a new form, would provide a more powerful tool for clinical research in an era full of opportunities and challenges, with research value and potential.

Objective To study the impact of earthquake disasters on the mental health of military medical personnel during emergency rescue. Methods Three hundred military medical personnel who participated in the emergency rescue of earthquake disasters in five military hospitals in Shaanxi Province were selected as the study subjects, and their mental health levels were analyzed using the Mental Symptom Checklist 90 (SCL-90). Results In this survey, a total of 300 SCL-90 questionnaires were issued, 300 were recovered, and the effective recovery rate was 100%. Only 30.67%(92/300) of people participated in emergency disaster rescue during investigation, 31.33% (94/300) had psychological problemsafter arriving in the earthquake-stricken area after one week, such as somatization, obsessive-compulsive disorder, anxiety, and horror. SCL-90 scores were 0.45±0.03, 1.13±0.13, 0.79 ±0.08, 1.07±0.09, 1.01±0.14. The psychological stress response rates of the emergency response of military medical staff of different characteristics were different. Among them, the stress response rates of military personnel with different degrees (specialty, bachelor or above) and whether they have participated in rescue work were 74.07% (40/54), 21.95% (54/246), 15.22% (14/92), 38.46% (80/208).The difference was statistically significant (χ2=55.913,16.018, P<0.01). Conclusions The medical staff of the army participating in the earthquake disaster rescue has psychological pressure due to many injuries, environmental risks, lack of supplies, etc. The medical unit should provide adequate training in theory and practice to its personnel and focus on the mental health of rescue workers, give timely psychological counseling to ensure the successful completion of the rescue.
