Objective To investigate and analyze the recent condition of the indoor air radon concentration in the colleges in Guangzhou and to find the source of radon in the teaching environments and to make the effective measure to reduce indoor air radon pollution. Methods The radon concentration was determined with the instantaneous and accumulate methods. The effecting factors were analyzed. Results The arithmetic average of radon concentration was about (34.2?21.17) Bq/m3. The indoor radon concentration in the newly decorated buildings was about (36.6?25.5) Bq/m3 which was higher than that in the old ones (20.1?8.48) Bq/m3. The indoor radon concentration in the night was higher than that in the daytime. In winter it was about (54.2?15.11)Bq/m3 which was higher than that (17.3?7.31) Bq/m3 in summer. Conclusion The radon concentration may change as the outside condition changes, the radon concentration in the teaching environment in Guangzhou is not over the standard limit.

Objective:To investigate the effect of life review therapy on spiritual comfort and dignity among patients with advanced bladder cancer, to provide reference for the improvement of quality of death outcomes.Methods:A total of 60 patients with advanced bladder cancer who were admitted to the Cancer Hospital of the University of Chinese Academy of Sciences from March 2018 to January 2020 were selected as the research objects. Randomly divided all the patients into the control group and the experimental group, 30 cases in each group. The control group was given routine end-of-life care, and the experimental group was given 5 times of life review therapy on the basis of the control group. The effect of the intervention was evaluated by the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale(FACIT-Sp-12) and the Patient Dignity Inventory (PDI).Results:Finally, there were 28 cases in the experimental group and 29 cases in the control group. After the intervention, the scores of peace, meaning and belief demensions and total scores in FACIT-Sp-12 in the experimental group were (10.61 ± 2.23), (11.14 ± 1.90), (10.67 ± 1.79) and (32.36 ± 3.28), respectively, which was significantly higher than those in the control group (8.34 ± 2.24), (10.03 ± 1.49), (8.66 ± 1.89) and (27.03 ± 3.61), the differences were statistically significant ( t values were 2.45-5.82, all P<0.05). The psychological state, dependence, mental peace, social support demension scores and total scores of PDI in the experimental group were (8.64 ± 2.06), (3.14 ± 0.89), (4.21 ± 0.79), (2.43 ± 0.69) and (28.46 ± 4.98), which were significantly lower than those in the control group (10.34 ± 2.93), (4.17 ± 1.17), (4.93 ± 1.33), (3.17 ± 1.07) and (34.01 ± 4.79), the differences were statistically significant ( t values were 2.48-4.28, all P<0.05). Conclusions:Life review therapy can promote spiritual comfort and alleviate dignity destroyed in patients with advanced bladder cancer.

Objective: To explore the statue quo of psychological resilience of breast cancer patients during chemotherapy period and its influencing factors. Methods: From December 12 to May 2018, Totally 165 breast cancer patients during chemotherapy period in Department of Mammary Chemotherapy of Zhejiang Cancer Hospital were investigated by self-designed demographic questionnaire, the Connor-Davidson Resilience Scale and the Medical Coping Modes Questionnaire. Results: The total score of psychological resilience for breast cancer patients during chemotherapy period was (60.26±16.17)points.Multiple regression analysis showed that marital status, transfer, confront and resignation coping style were the influencing factors for psychological resilience(t=-3.048, 3.216, 3.070, -3.044, all P<0.05). Conclusion The level of psychological resilience of breast cancer patients is poor and multivariate analysis appears that marital status, transfer, confront and resignation coping style are important influencing factors.
