Objective To analyze the present situation and reasons of short-term unplanned extubation after peripherally inserted central venous catheters (PICC)surgery in cancer patients. Methods A total of 2 458 cancer patients underwent PICC surgery were collected,and patients experienced short-term unplanned extubation were screened out to analyze the general information, catheter situation and reasons of unplanned extubation.Results Totally 2 431 cases (98.90%, 2431 /2458)were successfully followed-up and 103 patients (4.24%,103 /2431)experienced short-term unplanned extubation.Among them,the proportion of patients received primary PICC,pa-tients over 65 years old and patients with catheter located in median cubital vein were 96.12%(99 /103),59.22% (61 /103)and 46.60% (48 /103)respectively.The incidence of unplanned extubation were related to age,vascular choose and whether the primary PICC.Subjective will (61.17%,63 /103)of patients was the main reason for short-term unplanned extubation and the objective reasons were catheter prolapse (10.67%,11 /103),local thrombosis (7.77%,8 /103) and puncture site exudation /phlebitis(6.80%,7 /103),catheter-related infections (5.83%,6 /103)and so on.Conclusion Effective maintenance during the entire process after PICC such as adequate doctor-patient communication,positive patient education,strengthening outside hospital PICC maintenance training as well as establishment of good follow up system can reduce the inci-dence rate of short-term unplanned extubation.

Objective To investigate the prevalence of post-traumatic stress disorder (PTSD) in the army and the effects of social support and interpersonal relationship on PTSD, so as to provide basis for understanding the mental health level of the army and further interventions.Methods Purposive sampling was performed to select the soldiers of one field army in Inner Mongolia Province from July to August 2016. According to the post-traumatic stress disorder scale civilian version (PCL-C), the soldiers were divided into experimental group and control group. Social support rating scale (SSRS) and self-made demographic questionnaire were used for evaluation in the study.Results The scores of objective support, support utilization, family relationship and relationship with others in the soldiers in the experimental group decreased compared to the control group, whereas statistically significant difference was observed (t=2.235,3.544,2.477,2.485;P<0.05). The severity of PTSD was significantly negatively correlated with the scores of relationship with others (r=-0.458, P=0.032), but not correlated with objective support, support utilization and family relationship (P>0.05). Conclusions Low objective support and support utilization, poor family relationship and relationship with others can result in a higher prevalence of PTSD,but the severity of PTSD is only negatively related to the scores of relationship with others.

Objective To investigate prevalence and influencing factors of post-traumatic stress disorder (PTSD) and anxiety of soldiers to provide clinical evidences in improving their psychological health. Methods A total of 168 soldiers from Inner Mongolia Autonomous Region in November 2016 were selected using cluster sampling. PTSD was assessed by Post-Traumatic Stress Disorder Scale (PCL-C). Anxiety was assessed by Self-Rating Anxiety Scale (SAS). Related factors of PTSD and anxiety were analyzed by correlation analysis. Multiple regression analysis was used to explore predictive indexes of anxiety. Results A total of 155 vulid samples were selected amung 168 soldiers in total in this study. Among 155 soldiers, the positive rate of PTSD was 14.2%; the positive rate of anxiety was 16.1%, and 36.4% of PTSD patients were accompanied with anxiety. PTSD and anxiety symptoms were positively associated with age (P<0.05), and negatively associated with objective support, support utilization, relationship with family and relationship with others (P< 0.05). Multiple regression analysis showed that support utilization, relationship with family and relationship with others could predict the severity of anxiety (F=14.895, P<0.01). Conclusions The occurrence of PTSD and anxiety are higher in soldiers. PTSD is more likely to be accompanied with anxiety, and the related factors of PTSD and anxiety are the same. The higher comorbidity of these two diseases may be due to the shared related factors of them, which emphasizes the importance of assessing and treating anxiety and PTSD at the same time to achieve better outcomes.
