Objective To investigate the status and influence factors on mental health among young stuberculosis patients, and explore the correlation between mental health and social support, so as to provide scientific basis for the development of interventions.Methods A total of 200 young tuberculosis patients, aged ≤40 year, were selected in Xuzhou Infectious Hospital from May 2015 to August 2016,and investigated by self-designed general information questionnaire, Symptom Checklist (SCL-90) and Social Support Rating Scale (SSRS). The correlations were analyzed between mental health and social support.Results Compared with 1986 and 2006 national norm, the sum score of SCL-90 was (147.34±46.39) for involved youth (t=5.298, 5.280;P<0.05). In multiple regression analysis, the main influence factors included educational level, annual income for score of SCL-90. The score of SCL-90 was negatively correlated with scores of social support, subjective support and degree of support utilization (r=-0.232, -0.221, -0.407;P<0.05).Conclusions The mental health status of young patients with tuberculosis is poor, and social support is closely related to mental health. Medical staff should timely carry out psychological intervention measures to improve the mental health and promote the rehabilitation.

Objective: To compare the calibration result of standard X-ray RQR radiation field between SSDL (NIRP) and CEA LIST LNHB(France), and to explore the feasibility of calibrating H_p(3) in standard X-ray RQR radiation field of SSDL(NIRP). Methods: Using a column model with a diameter and high of 20 cm, TLD was calibrated in SSDL (NIRP) and CEA LIST LNHB (France) to measure the personal dose equivalent eye lens dose H_p(3), X-ray RQR radiation field included RQR4(60 kV), RQR7(90 kV), RQR9(120 kV), with energy response, angle response and linear response. Results: In terms of energy response, the calibration results of TLD in both SSDL (NIRP) and CEA LIST LNHB (France) were in good agreement. The difference between exposure value and response value was less than 10%. In terms of angle response, the calibration result of TLD in CEA LIST LNHB (France) was better in SSDL(NIRP). The difference between exposure value and response value in CEA LIST LNHB (France) was less than 6%, while the difference between exposure value and response value in SSDL(NIRP) was more than 10% at angle of 20°. In terms of linear response, both calibration result of SSDL (NIRP) and CEA LIST LNHB (France) were in good agreement. Conclusions The standard X-ray RQR field in SSDL (NIRP) can be used for the calibration of H_p(3).
