Objective To explore the factors affecting the quality of psychological assistance hotline connections in Shaanxi Province, and to provide a basis for optimizing services. Methods A total of 149 calls with suicidal tendencies were included from January to March 2022, and data were collected by 31 trained assessors through standardized questionnaires (general information, suicide risk, emotional intensity, and wiring characteristics). Results The results showed that 56.38% of the callers were female, with age groups concentrated between ≤ 18 years old (29.53%) and 19-34 years old (43.62%). The call duration was mainly between 31 and 45 minutes (50.34%). Operators conducted a suicide risk assessment on the callers, with 38.9% having a comprehensive assessment, 38.9% having an incomplete assessment, and 22.1% having no assessment. The main mental disorders of the callers were depression (48.32%), anxiety (15.44%), and bipolar disorder (14.77%), with 25.50% having comorbidities of ≥ 2 disorders. Emotional scores were as follows: depression (4.11 ± 0.76), sadness (3.97 ± 1.03), and despair (3.78 ± 1.05). There were significant differences in depression, anger, despair, and sadness among the callers with different levels of danger (t=4.79, 3.35, 15.79, 4.24, all P<0.05). Women had higher levels of fear than men (t=3.10, P<0.01). The longer the call duration, the higher the level of despair (t=5.66, P<0.01). Multiple regression analysis showed that incomplete suicide risk assessment by operators (B=-2.36), general procedures for operators' connections (B=5.44), and technical factors (B=2.01) significantly affected the quality of psychological assistance hotlines (all P<0.05). Conclusion Callers with suicidal tendencies generally have serious mental and psychological problems and prominent negative emotions. Strengthening the suicide risk assessment ability of operators and standardizing processes and service attitudes are key to improving the quality of psychological assistance hotlines.

OBJECTIVE：To compare the eff icacy and safety of rivaroxaban versus enoxaparin in the treatment of malignant tumor complicated with venous thromboembolism （VTE），and to provide evidence-based reference to the clinic. METHODS ： Retrieved from PubMed ，Embase，Cochrane Library ，Clinical Trials ，CNKI，CBM and VIP ，clinical trials or observational studies about rivaroxaban versus enoxaparin were collected during the inception to Apr. 2020. After literature screening and data extraction ， the quality of included literatures were evaluated by Newcastle Ottawa scale ；Stata 15.0 software was used to conduct Meta-analysis，sensitivity analysis and publication bias analysis. RESULTS ：A total of 5 observational clinical cohort studies were retrieved，including 4 retrospective cohort studies and one prospective cohort study. Totally 997 patients were included ，among which 625 patients received enoxaparin and 372 patients received rivaroxaban. Results of Meta-analysis showed that there was no statistical significance in recurrence rate of VTE at 3 months follow-up [RR ＝0.91，95％CI（0.50，1.66），P＝0.760] and 6 months follow-up [RR ＝0.53，95％CI（0.24，1.15），P＝0.106] as well as the incidence of massive hemorrhage at 3 months follow-up [RR ＝ 1.22 ，95％CI（0.66，2.25），P＝0.530] and 6 months follow-up [RR ＝1.30，95％CI（0.73，2.33），P＝0.368]. The results of sensitivity analysis showed that the results of above Meta-analysis were stable ；the results of publication bias analysis showed that there was less possibility of publication bias in this study. CONCLUSIONS ：Rivaroxaban is as effective and safe as enoxaparin in the treatment of malignant tumor with VTE.
