Objective:At present,the doctor-patient relationship is tense.The prevalence of negative emotions,such as depression and anxiety,among healthcare workers is increasing every year.Negative attitudes of medical workers toward mental problems may aggravate the doctor-patient conflict and psychological problems of medical workers.This study aims to explore the complex network relationships between outpatient medical workers'attitudes toward mental problems,doctor-patient relationships,and their depression/anxiety levels. Methods:A total of 578 outpatient medical staff from the Second Xiangya Hospital of Central South University(167 males,411 females)completed questionnaires on their attitudes toward mental problems,doctor-patient relationships,and depression/anxiety symptoms.Network analysis was conducted separately to construct the"attitude towards mental problems-doctor-patient relationship network"and"depression-anxiety related network". Results:The edge between"M15(insulting words)"and"D8(waste time)"showed the strongest strength in the"attitude towards mental problems-doctor-patient relationship network",and"M15(insulting words)"had the highest bridge strength in the network.For the analysis of emotional variables,"P1(anhedonia)"showed the most obvious association with"D10(communication difficulties)"in the doctor-patient relationship and"M2(poor quality of life)"in the psychiatric attitudes,and"P1(anhedonia)"was the key bridge symptom in the network. Conclusion:The"insulting words"may be an intervention target for medical workers'attitudes toward mental problems.The"anhedonia"in depression is the potential symptom that needs to be treated.Intervention targeting these variables may be beneficial to improve the mental health level of medical workers and the doctor-patient relationship.

Objective:To determine the biomechanical stability of atlantoaxial and occipitocervical fixations with unilateral spinous process screw plus contralateral pedicle screw.Methods:After nonlinear finite element models of the intact upper cervical spine (C0-3) were constructed and validated, they were processed into 3 kinds with normal axis anatomy, a high-riding vertebral artery and a thin axis lamina, re-spectively.In the models, the odontoid fracture stabilized by atlantoaxial fixation and the atlas fracture sta-bilized by occipitocervical fixation were simulated.In the atlantoaxial fixation, the group of unilateral spinous process screw+contralateral pedicle screw+bilateral atlas lateral mass screws (spinous process screw group) was compared with that of bilateral axis pedicle screws+bilateral atlas lateral mass screws (pedicle screw group); in the occipitocervical fixation, the group of unilateral spinous process screw+contralateral pedicle screw+occipital screws (spinous process screw group) was compared with that of bilateral axis pedicle screws+occipital screws (pedicle screw group).Three different techniques in insertion of spinous process screws (horizontal, oblique and vertical) were applied.The range of motion (ROM) was measured in extension-flexion, lateral flexion and rotation of occipitocervical bodies (C0-C3) after internal fixation.Results:Compared with the intact models, the ROMs of extension-flexion, lateral flexion and rotation of C1-C2 were obviously reduced in the spinous process screw group and the pedicle screw group in the models with atlantoaxial and occipitocervical fixations.In the atlantoaxial fixation, the ROMs of extension-flexion, lateral flexion and rotation of C1-C2 were greater in the spinous process screw group than in the pedicle screw group; in the occipitocervical fixation, the spinous process screw group had greater ROM of lateral flexion of C1-C2 and greater ROM of rotation of C0-C2 than the pedicle screw group.There were unobvious differences in insertion of spinous process screws between the horizontal, oblique and vertical techniques.Conclusions:In the atlantoaxial and occipitocervical fixations, the unilateral spinous process screw plus contralateral pedicle screw can provide as fine stability as the bilateral axis pedicle screws.In the atlantoaxial fixation, the bilateral axis pedicle screws may lead to better stability of C1-C2 than the unilateral spinous process screw plus contralateral pedicle screw.In the occipitocervical fixation, the bilateral axis pedicle screws may lead to better stability of C1-C2 in lateral flexion and rotation than the unilateral spinous process screw plus contralateral pedicle screw. The 3 different techniques in insertion of spinous process screws lead to an unobvious difference in the stability of C1-C2.

OBJECTIVETo analyze interpersonal sensitivity level and influencing factors among patients in methadone maintenance treatment.
METHODSFrom 2010 June to 2011 June, the research was performed in Center of Methadone Maintenance Treatment of Nanjing Baixia District Hospital. A total of 272 methadone maintenance treatment was studied using a self-designed questionnaire, interpersonal sensitivity scale in symptom check list (SCL-90), self-rating depression scale (SDS), self-rating anxiety scale (SAS). If interpersonal sensitivity level ≥ 2 points, it was positive. In this study, through independent sample t test, analysis of the social demographic characteristics, depression and anxiety, interpersonal sensitivity level. Non conditional logistic regression analysis was used to explore a variety of factors, and the relationship of these factors with interpersonal sensitivity.
RESULTSThe depression score, the anxiety score and the level of interpersonal relationship sensitivity in 272 methadone maintenance treatment (1.65 ± 0.51, 47.66 ± 8.58, 42.38 ± 9.40) was higher than the national norm (1.65 ± 0.51, 41.88 ± 10.57, 29.78 ± 0.46) (t values were 8.23, 17.63 and 22.27, respectively; all P values < 0.001). In 272 methadone maintenance treatment, the percentage of men was 75.0% (204/272) and the percentage of women was 25.0% (68/272). SDS score of male and female was (48.38 ± 8.30) and (45.90 ± 9.34) points (t = 5.67, P = 0.037); Aged 20-29, 30-39, 40-49 and ≥ 50 years old group, SDS scores were (48.26 ± 7.59), (47.73 ± 8.38), (47.79 ± 9.22) and (48.09 ± 6.33) points (F = 3.90, P = 0.046); According to the drug's time, divided into 1-3, 4-6 and ≥ 7 years group, SDS scores were (45.92 ± 7.47), (47.41 ± 7.57) and (48.07 ± 8.57) points (F = 4.49, = 0.039). SAS score of male and female was (41.21 ± 9.53) and (42.91 ± 9.42) points (t = 2.23, P = 0.043). The positive rate of interpersonal sensitivity was 47.1% (128/272). Multivariate analysis showed that, with SDS and SAS scores increased by 1, respectively, interpersonal sensitivity increased 23.23 (8.62-96.68) and 11.97 (6.42-19.27) points.
CONCLUSIONInterpersonal sensitivity level in methadone maintenance treatment was higher than normal and depression; anxiety and depression both were the risk factors of interpersonal sensitivity level.
