Objective:To investigate the anxiety and depression of cancer patients undergoing radiotherapy during the epidemic of COVID-19.Methods:By using self-rating anxiety scale and self-rating depression scale, a cross-sectional survey was conducted during the COVID-19 epidemic period.Results:During the COVID-19 epidemic period, the incidence of anxiety and depression in cancer patients undergoing radiotherapy was 15.8% and 27.7% respectively, of which 12.9% suffered from both anxiety and depression. The average scores of anxiety and depression were 49.4(25/76) and 46.4(25/83), respectively, which were higher than those of the domestic norm. Age is a contributing factor for anxiety, and patients living in urban are more likely to experience depression.Conclusions:The prevalence of anxiety and depression of cancer patients undergoing radiotherapy are higher than healthy people during the COVID-19 outbreak. We should pay more attention to the psychological states of the cancer patients.

OBJECTIVE： To study the improving effects of echinacoside （ECH） on spatial cognitive function in mice under hypobaric hypoxia environment and its mechanism. METHODS： Totally 60 mice were randomly divided into blank group （normal saline）， model group （normal saline）， positive group （Ginkgo leaf extract tablet，100 mg/kg） and ECH low-dose， medium-dose and high-dose groups （50， 75， 100 mg/kg）， with 10 mice in each group. Except for blank group， other groups were cultured in hypobaric oxygen chamber to simulate hypobaric hypoxia； they were given relevant medicine intragastrically once a day， for consecutive 7 d （Placing into hypobaric oxygen chamber immediately after medication）. Using the times of horizontal and vertical activities of mice in 2 min as index， negative emotions and spatial cognitive function were evaluated. Histopathological changes of hippocampus in mice were observed by microscopy after HE staining. The levels of SOD， CAT， GSH-Px and MDA in hippocampal tissue of mice were detected. RESULTS： Compared with blank group， the times of horizontal activities， MDA level were increased significantly in model group （P＜0.05）， while the times of vertical activities， the levels of SOD， CAT and GSH-Px were decreased significantly （P＜0.05）； the pyramidal cells in the CA1 area of the hippocampal tissue were arranged loosely， and many pyramidal cells were compressed and stained deeply. Compared with model group， the times of horizontal activities and MDA level were decreased significantly in positive group and ECH high-dose group （P＜0.05）， while the times of vertical activities， the levels of SOD， CAT and GSH-Px were increased significantly （P＜0.05）； the pyramidal cells in the CA1 region of the hippocampal tissue were abundant and closely arranged， and a few of them are constricted and deeply stained. CONCLUSIONS： ECH can improve spatial cognitive impairment of mice under hypobaric hypoxia environment， the mechanism of which may be associated with up-regulation of SOD， CAT and GSH-Px， down-regulation of MDA in the hippocampal tissue.

Objective To investigate the quality of life, sexual quality of life and its influencing factors in cervical cancer patients undergoing radiotherapy. Methods Pre-menopausal patients of 87 cases were diagnosed with cervical cancer treated with radiotherapy at Peking Union Medical College Hospital from December 2013 to December 2018 were recruited in this study. The functional assessment of cancer therapy-cervix ( FACT-Cx V4. 0) and the female sexual function index ( FSFI) were evaluated. Demographic and treatment data were collected. The influencing factors were analyzed by multiple linear regression analysis. Results The total score of quality of life was 114( 100-126) , 19( 16-21) for physiology, 21( 18-24) for social/family, 19( 17-21 ) for emotion, 19 ( 14-22 ) for function and 39 ( 34-43 ) for additional attention, respectively. The end time of radiotherapy was the influencing factor of the total score ( P= 0.034 ) , physiology ( P=0) and function ( P=0.008) . Family was the influencing factor of social family dimension ( P=0.010) . The total score of FSFI was 8.0( 5.0-20.5) , 1.8( 1.2-3.0) for sexual desire, 1.5( 0-2.7) for sexual arousal, 0.3( 0-3.6) for vaginal lubrication, 0( 0-3.6) for orgasm, 3.2( 2-4) for satisfaction and 0( 0-3.6) for sexual pain, respectively. The total score was less than 27 in 97%( 84/87) of the patients and had sexual dysfunction. Age was the influencing factor of sexual arousal ( P=0.005) and vaginal lubrication ( P=0.039) . Occupation was the influencing factor of sexual pain ( P=0.004) . Conclusions The quality of life of premenopausal patients with cervical cancer is affected by multiple factors. Radiotherapy-related complications should be actively treated to improve the quality of life and sexual life of patients.
