ABSTRACT

Objective:To investigate the influence of childhood traumatic experience on internet addiction of adolescents and the mediating effect of self-concealment.Methods:Childhood trauma questionnaire(CTQ), self-concealment scale(SCS) and adolescent pathological internet use scale(APIUS) were used to investigate 532 college students.SPSS 22.0 was used for descriptive statistics, correlation analysis and regression analysis.Amos 24.0 was used for confirmatory factor analysis, and the relevant assumptions were verified through structural equation model.Results:The total scores of childhood abuse, self-concealment and adolescent pathological internet use were (37.23±11.91), (26.09±9.26) and (82.15±28.09), respectively.Correlation analysis showed that childhood trauma was positively correlated with self-concealment ( r=0.27, P<0.01). Self-concealment was positively correlated with internet addiction ( r=0.47, P<0.01). Childhood trauma was positively correlated with internet addiction ( r=0.36, P<0.01). Mediating effect test showed that childhood trauma had a significant positive predictive effect on self-concealment ( β=0.34, P<0.01), self-concealment had a significant positive predictive effect on internet addiction ( β=0.34, P<0.01), and childhood trauma had a direct predictive effect on internet addiction ( β=0.31, P<0.01). Conclusion:Childhood trauma and self-concealment have significant influence on internet addiction, and self-concealment plays a partial mediating role between childhood trauma and internet addiction of adolescents.

ABSTRACT

Angiokinases, such as vascular endothelial-, fibroblast- and platelet-derived growth factor receptors (VEGFRs, FGFRs and PDGFRs) play crucial roles in tumor angiogenesis. Anti-angiogenesis therapy using multi-angiokinase inhibitor has achieved great success in recent years. In this study, we presented the design, synthesis, target identification, molecular mechanism, pharmacodynamics (PD) and pharmacokinetics (PK) research of a novel triple-angiokinase inhibitor WXFL-152. WXFL-152, identified from a series of 4-oxyquinoline derivatives based on a structure-activity relationship study, inhibited the proliferation of vascular endothelial cells (ECs) and pericytes by blocking the angiokinase signals VEGF/VEGFR2, FGF/FGFRs and PDGF/PDGFR simultaneously . Significant anticancer effects of WXFL-152 were confirmed in multiple preclinical tumor xenograft models, including a patient-derived tumor xenograft (PDX) model. Pharmacokinetic studies of WXFL-152 demonstrated high favourable bioavailability with single-dose and continuous multi-dose by oral administration in rats and beagles. In conclusion, WXFL-152, which is currently in phase Ib clinical trials, is a novel and effective triple-angiokinase inhibitor with clear PD and PK in tumor therapy.

ABSTRACT

Objective:To investigate the cognition of terminal stage patients'dignity therapy,attitude towards its concept and scheme,willingness of its promotion in college students and to gain some recommendations for improvement.Methods:Combined quantitative and qualitative methods,an anonymous questionnaire survey was conducted in a convenience sample of 220 college students,of which 20 students were selected for in-depth interviews.Results:Only 17.73% of students had a correct understanding of dignity therapy,94.98% of them accepted its concept,92.96% of them held a positive attitude,74.38% of them were willing to promote dignity therapy,in which female students were dominated (P =0.041).Interview results showed that the contents of dignity therapy were to some extent stiff and not fit for Chinese patients,which might impede its promotion.Conclusion:College students lack the cognition of dignity therapy.But they hold a positive attitude and are willing to promote dignity therapy when they get to know its concept and contents.As seen,dignity therapy has a good future but there are still some obstructions in the promotion,and need to be localized.
