Objective To explore the relations of the doctor-patient relationship to psychological security and stress.Methods Totally 430 operation patients were selected and followed-up.A survey was performed using the Security Questionnaire (SQ),the Patient Doctor Relationship Questionnaire 13-Item Version (PDRQ-13),the Hospital Stress Rating Scale (HSRS) Results The average score of SQ was lower than medium value in operation patients.The SQ scores of operation patients with emergency operation were 39.50±10.51,lower than those of selective operation which were 49.02±10.37 and limited operation which were 47.67±10.29 (P ＜ 0.05).The SQ scores of operation patients who didn't provided themselves were 37.33±10.10,lower than those of basically which were 40.10±10.83 and partly provided for themselves which were 43.50±10.51 (P＜ 0.05).The SQ scores of operation patients in severe group according severity of illness were 37.13±10.40,lower than those of them in mild group which were 39.19±10.24 and moderate group which were 41.38±10.01 (P＜ 0.01).The SQ scores of post-operation patients were 44.32±9.96,higher than post-operation patients which were 40.36±10.81 (P ＜ 0.01).The lack of comforts (LC),lack of information (LI) and risks of serious disease (RSD) scores of post-operation patients were 49.23±30.62,30.46±21.42,52.84±31.22,lower than those of post-operation patients which were 52.37±32.06,35.25±20.14,80.12±33.18 (P ＜ 0.05).The path analysis showed that the regression relationship between SQ scores and PDRQ scores,RSD scores was established (β=0.40,-0.26,P ＜ 0.01),and the PDRQ-13 scores was a mediator between the scores of LC,LI,RSD and the SQ scores (β=0.40,P＜0.01).The PDRQ-13 scores was a adjustor between the RSD scores and the SQ scores (β=-0.34,P ＜ 0.01).Conclusions The operation patients have a low level of the sense of security which is statistically significant with surgical types,the ability to care for themselves and severity of illness.The sense of security of post-operation patients were higher than those of pre-operation patients.The recognition of physician-patient relationship may be play a mediating and adjusting role between the sense of security and stress.The surgical stress affect patient security and physician-patient relationship.

Objective To investigate the psychological status of parents when premature infants discharge from Neonate Intensive Care Unit (NICU) and analyze the influencing factors. Methods A total of 100 premature infants and 100 parents who had been hospitalized in NICU of Beijing Children's Hospital Affiliated to Capital Medical University from December 2015 to July 2016 were enrolled in the study. All the parents were investigated for their psychological status when premature infants were discharged from NICU by Symptom Checklist (SCL-90). SPSS 17.0 software was used to analyze and process the research data. Results The total score of SCL-90 was (134.60±21.77), of which the scores of 6 factors were on the high side:somatization (18.15±4.54), depression (22.10±3.72), anxiety (15.70±3.08), hostility (9.55±1.95) and terror (9.35±2.61). It showed that the score of mothers were higher than fathers. The SCL-90 score had a statistical difference in parents at different age group and with different education background (P<0.05). The differences of SCL-90 scores for parents of premature infants with different admission age, admission weight, discharge weight, and NICU time were statistically significant (P< 0.05). The results of multiple regression analysis showed that parents' gender, age and premature infants' admission age, admission weight, discharge weight and NICU time were the main influencing factors of parents' psychological status. Conclusions The psychological status of parents of premature infants when discharged from NICU is poor and affected by various factors. To construct personalized psychological adjustment strategies to improve the mental state of parents of NICU premature infants at discharge is of great significance for optimizing family nursing, improving the prognosis of premature infants, improving the compliance of parents and harmonizing the relationship between doctors and patients.
