Objective:
To understand the current situation of intimate partner violence (IPV) among young students in Chengdu and its relationship with emotion regulation self-efficacy,and to provide a reference for conducting the education on close relationship.
Methods:
Totally 1 041 young students with love experience in Chengdu were selected by by stratified cluster random sampling to explore potentional factors related to IPV.
Results:
The incidence of IPV perpetration among young students with love experience was as high as 69.6% and the incidence of IPV victimization was 62.2%. Young students had committed(65.4%) or been subjected(64.0%) to more than three intimate partner violence. 59.92% young students were both perpetrators and victims of IPV. Multiple Logistic regression analysis showed that compared with young female students, young male students were not prone to commit violence in intimate relationships(OR=0.59), but may become victims of IPV(OR=1.91). More than half a year in love(OR=1.70), cohabitation(OR=2.47), bullying by peers (OR=1.54) and interference by parents (OR=1.63) were risk factors for IPV perpetration. Among them, more than half a year in love (OR=1.51) and cohabitants (OR=2.52) were positively associated with IPV victimization. The efficacy of managing negative emotions was a negatively associated with IPV perpetration (OR=0.96) and victimization(OR=0.97)(P<0.05).
Conclusion
The phenomenon of intimate partner violence among young students is more common, which is closely related to the rearing style of young students, peer relationship, love relationship and the ability to manage negative emotions, which should be paid attention to.

Telemedicine can optimize deployment of medical resources and minimize diagnosis discrepancies.Formulation of a rational project pricing and scientific compensation policy will be conducive to its future development. The concept of human resource consumption in RBRVS was used as reference to improve the activity-based costing ( ABC ) method. The authors sorted out the resource cost repository, identified the activity system, classified the motivation resources into respective activity cost repositories, and calculated the cost of respective cost object distribution.The cost of three telemedicine service items(remote single discipline consultation, remote image consultation and remote pathology consultation were 119.69, 147.03 and 161.61 yuan respectively) was calculated by the improved ABC.It can better indicate project costs than that calculated by the traditional ABC(137.30, 147.17 and 144.08 yuan), and proves more consistent with the existing prices of other province(134.00, 150.00 and 174.00 yuan).
