Objective To confirm the mediation effect of trait coping styles between childhood a-buse and psychosomatic symptoms among college students. Methods 262 medical students were investiga-ted by Psychosomatic Health Questionnaire( PHQ) ,Personal Report of Childhood Abuse( PRCA) ,Trait Cop-ing Styles Questionnaire(TCSQ),Self-rating Anxiety Scale(SAS),Suicide Ideation Scale(SIS) and Beck Depression Inventory(BDI).Structural equation models were established by Amos 7.0. Results The positive coping scores of medical students were (34.70±4.50),and (27.48±5.68) for negative coping,(7.79±5.58) for depression,(29.40±6.22) for self rating anxiety,(1.33±1.75) for suicidal ideation,(1.26±0.51) for mental symptoms,(1.27±0.52) for somatic symptoms and (3.17±4.26) for behavioral problems.Abuse total score was positively correlated with negative coping style, depression, self rating anxiety, suicidal ideation, mental symptoms and behavioral problems ( r=0.148-0.417,P<0.05) ,and negatively correlated with positive coping style(r=-0.148,P<0.05).Negative coping style was positively correlated with Beck depression,self rating anxiety,suicidal ideation,mental symptoms and somatic symptoms( r=0.252-0.350,P<0.01) ,and neg-atively correlated with positive coping style(r=-0.309,P<0.01).Positive coping style was negatively correla-ted with Beck depression,self rating anxiety,suicidal ideation,mental symptoms and somatic symptoms ( r=-0.208--0.271,P<0.01).Structural equation modeling showed that childhood abuse had an direct effect on psychosomatic symptoms( B=0.290,P<0.01) ,positive coping styles( B=-0.129,P<0.05) and negative cop-ing styles(B=0.243,P<0.01) among medical students.Positive coping styles and negative coping styles had direct effect on psychosomatic symptoms(B=-0.194,P<0.01;B=0.263,P<0.01).The model fit indexes were χ2/df=1.576,PGFI=0.585,PCFI=0.689,PNFI=0.645,RMSEA=0.047,GFI=0.951,AGFI=0.920, NFI=0.900,RFI=0.858,IFI=0.960,TLI=0.943,CFI=0.959. Conclusion The results indicate that trait coping styles as a mediator mediating the relationship between childhood abuse and psychosomatic symptoms in medical students.

Objective To evaluate the effects of the application of high-flow nasal cannula (HFNC)for the respiratory failure following radical resection of pulmonary carcinoma. Methods A total of 48 patients with radicalsurgeryofpulmonarycarcinoma effect postoperative failure from February 2015 to August 2016 were randomly divided into observation group(24 cases) and control group(24 cases) with digital table method.The observation group was received with HFNC,and the control group with oxygen atomization mask 8-10 L/min.The heart rate,respiratory rate,PaO2,PaCO2and oxygenation index(PaO2/FiO2)changes were evaluated before treatment,treatment for 1,6,24 h and at the end of the treatment in both groups, at the same time, noninvasive positive pressure ventilation (NPPV) rate, again intubation mechanical ventilation rate, incidence of ventilator associated pneumonia (VAP), ICU confusion assessment (CAM-ICU) positive rates and ICU stay time were compared in the course of treatment of difference. Results Through two different methods of treatment, the heart rate, respiratory rate, PaO2, PaCO2,PaO2/FiO2were(78.88±12.03)times/min,(18.96±7.53)times/min,(140.2±18.37)mmHg(1 mmHg=0.133 kPa),(37.04±7.67)mmHg,(242.83±27.13)mmHg in the observation group,respectively,compared with(88.83±16.48)times/min,(25.46±9.51)times/min,(86.08±20.83)mmHg,(45.71±10.37)mmHg and(210.71±36.34)mmHg in the control group,which had significant differences(t=-3.922-3.415,P<0.05). The ICU stay time in the observation group was( 68.71 ± 32.38) h, respectively, which was much shorter than that in the contorl group(107.67±66.15) h, the difference was statistically significant (t=2.416, P<0.05). The occurrence rates of NPPV and the positive rates of CAM-ICU were16.7%(4/24),4.2%(1/24)in the observation group,respectively,compared with 45.8%(11/24),33.3%(8/24)in the control group,which had significant differences(x2=4.752,4.923,P<0.05). Conclusions HFNC is a new and effective way of oxygen therapy that can better improve circulation oxygenation,reduce PaCO2,reduce the rate of line of NPPV and CAM-positive rate in the ICU,and can shorten the patient's ICU stay time in the treatment of lung cancer patients with postoperative respiratory failure.

Standardized cardiopulmonary resuscitation (CPR) of patients prior to the arrival of emergency medical services can significantly improve survival rate after out-of-hospital cardiac arrest (OHCA). According to statistics, about 40% to 85% of CPR led to chest fractures, making bystanders alarm, and reducing the willingness of rescuing by CPR. Therefore, there is an urgent need to develop a CPR protection device that is convenient for placing in public places outside the hospital and conforms to the operation habit of freehand CPR. In view of the above problems, medical students majored in emergency and rescue medicine and anesthesiology in Xuzhou Medical University, together with students majored in product design in Southeast University, designed a portable CPR protection device under the guidance of doctors working in department of emergency medicine of the Affiliated Hospital of Xuzhou Medical University, and obtained the national invention patent authorization of China (patent number: ZL 2021 1 0309001.4) and the national utility model patent authorization of China (patent number: ZL 2021 2 0591084.6). The device is composed of a foldable frame, support components, guide slide rails and compression body, which provides guidance and guarantee for the implementation of CPR, thus users can accurately grasp the implementation process, compression amplitude, strength and frequency, and effectively prevent accidental injuries such as rib fractures caused by CPR compression. The device is small, easy to store and move, with low manufacturing cost, making it suitable for social popularization.

Objective:To investigate the effect of post-traumatic pain on post-traumatic stress disorder (PTSD).Methods:A prospective trial was conducted with the recruitment of patients referred to the Emergency Center of Affiliated Hospital of Xuzhou Medical University for acute trauma from January 2018 to June 2019, with the exclusion criteria: age < 18 years, severe eye injury, severe craniocerebral injury and other critical conditions. The clinical data and written informed consent were collected at admission, the post-traumatic pain was assessed by VAS scores and the trauma severity was assessed by ISS score. APACHEⅡ score were evaluated within 24 h after admission. One month after trauma, patients with history of mental illness, or history of major psychogenic trauma within one year or drug addiction were further excluded. Accordingly, 64 eligible patients were evaluated by VAS, and the PCL-5 scale was used to evaluated their PTSD symptoms. The patients were divided into the PTSD group and non-PTSD group according to PCL-5 score≥ 38, and the difference between the two groups in post-traumatic VAS scores was compared. Logistic regression analysis was used to analyze the risk factors of PTSD. Spearman correlation analysis was adopted to establish the correlation between VAS score at admission and PCL-5 score at one month after trauma. The receiver operator characteristic (ROC) curve was used to analyze the predictive value of traumatic pain intensity for PTSD onset.Results:Sixty-four patients were selected and defined as the PTSD group ( n=19) and non-PTSD group ( n=45). The VAS score at admission was significantly higher in the PTSD group than that in the non-PTSD group ( P=0.006). There was no significant difference in VAS scores and VAS variations at 1 month, and in ISS scores at admission and APACHEⅡ scores within 24 h after admission between the two groups. Traumatic pain was an independent risk factor for PTSD ( P=0.043). VAS score at admission was positively correlated with PCL-5 score at 1 month post-traumatically ( r=0.355, P=0.004). In addition, ROC curve analysis showed that VAS score > 8 at admission had predictive value for PTSD (sensitivity=100%, specificity=33%, P=0.000 2). Conclusions:Post-traumatic severe pain is an independent risk factor for PTSD, which requires prompt medical intervention.
