Objective:To explore the mediating role of rumination thinking between demoralization and quality of life in malignant tumor patients, provide guidance and reference for helping tumor patients overcome rumination thinking and demoralization and improve quality of life.Methods:From February 2020 to June 2022, 189 patients with malignant tumors admitted to the Department of Oncology of the First Affiliated Hospital of Guangxi Medical University were selected by convenience sampling method as the research objects, and a cross-sectional survey was conducted using general information questionnaire, Demoralization Scale-Mandarin Version, Ruminative Responses Scale, Punctional Assessment of Cancer Therapy-General.Results:Among 189 malignant tumor patients, there were 102 males, 87 females, aged (43.54 ± 13.12) years old. The total score of loss of demoralization was (34.37 ± 10.34) points, the total score of rumination thinking was (41.01 ± 17.10) points, the total score of quality of life was (48.51 ± 15.41) points. The Pearson analysis results showed that the total score of demoralization in malignant tumor patients was negatively correlated with the total score of quality of life ( r = -0.502, P<0.01); the total score of rumination thinking was negatively correlated with the total score of quality of life ( r = -0.465, P<0.01), and the total score of demoralization was positively correlated with the total score of rumination thinking ( r = 0.628, P<0.01). Bootstrap mediation test results showed that ruminant thinking played a partial mediating effect between demoralization and quality of life of patients with malignant tumors, accounted for 30.9% of the total effect. Conclusions:Rumination plays a partially mediating role in the demoralization and quality of life of patients with malignant tumors, suggesting that clinical staff can improve the quality of life of patients with tumors by developing a systematic and comprehensive cognitive-behavioral intervention strategy to improve the demoralization and rumination.

With completing a baseline survey of a large natural population cohort, conducting regular follow-up has become a key factor in further improving the quality of cohort construction and ensuring its sustainable development. Typical cohort follow-up methods include repeat surveys, routine monitoring, and community-oriented surveillance. However, in practical applications, there are often issues such as high costs, difficulty, and high error rates. Telephone follow-up is an important supplementary method to the methods mentioned above, as it has the characteristics of low cost, fast response, and high quality. However, the with difficult organization, quality control is challenging, response rates are low, and management levels vary widely, which limits its widespread use in large-scale population cohort studies. Given the above problems, this study draws on customer relationship management based on the actual needs of the China Northwest Cohort follow-up. It relies on the REDCap electronic data collection platform to build a telephone follow-up management and quality control system. Targeted solutions are provided for key issues in telephone follow-up implementation, including organizational structure, project management, data collection, and process quality control, to improve the quality control level of telephone follow-up comprehensively and thereby enhance the quality and efficiency of follow-up. We hope to provide standardized follow-up programs and efficient quality control tools for newly established and existing cohort studies.

Objective: To explore latent classes of college students aggressive behavior and its correlations with family care and the meaning of life among college students. Methods: A cross sectional questionnaire survey was conducted among 5 094 students from three universities in Xinxiang City in December 2021, using Aggression Questionnaire (AQ), Family APGAR Index (APGAR), and the Meaning in Life Questionnaire (MLQ). Results: Aggressive behavior of college students was classifed into three potential categories:low aggressive behavior group (26.4%), moderate aggressive behavior group (48.5%), and high aggressive behavior group(25.1%). There were significant differences in latent classes of aggressive behavior among college students by gender, physical flexibility, exercise frequency, and sleep status ( χ 2=63.95, 169.86, 125.76, 325.24, P <0.01). There were significant differences in the sense of life meaning and the degree of family care among the 3 potential categories of aggressive behavior ( F=113.47, 231.82, P <0.01). The multivariate Logistic regression analysis showed that the sense of meaning of life ( OR =0.96, 95% CI =0.96-0.97) and family care ( OR =0.83, 95% CI =0.81-0.84) were significantly associated with three classes of aggressive behavior ( P <0.01). Conclusion Aggressive behavior among college students is associated with gender, exercise frequency, sleep status, meaning of life, family care, and physical flexibility. School, family and society should actively pay attention to students psychological characteristics and to provide corresponding support for aggressive behavior prevention and intervention.

Objective:To investigate the effects of cone beam computed tomography measurement of maxillary anterior teeth on implant success and patient satisfaction of maxillary anterior teeth.Methods:120 patients who underwent maxillary anterior teeth implantation in Hangzhou Dental Hospital from October 2017 to October 2019 were included in this study. They were randomly assigned to receive either conventional maxillary anterior teeth implantation (control group, n = 60) or cone beam computed tomography measurement of maxillary anterior teeth and maxillary anterior teeth implantation (study group, n = 60). The implant success rate was compared between the two groups. Alveolar bone thickness and ISQ value immediately, 3 and 12 months after implantation as well as patient satisfaction were compared between the two groups. Results:Implant success rate in the observation group was significantly higher than that in the control group [96.67% (58/60) vs. 85.00% (51/60), χ2 = 4.904, P < 0.05]. In the observation group, alveolar bone thickness at 3 and 12 months after implantation was (1.53 ± 0.05) mm and (1.78 ± 0.12) mm, respectively, which was significantly higher than that in the control group [(1.46 ± 0.04) mm, (1.64 ± 0.10) mm, t = 9.839, 8.066, both P < 0.001]. In the observation group, ISQ value at 3 and 12 months after implantation was (76.83 ± 5.49) and (82.91 ± 4.85), respectively, which was significantly higher than that in the control group [(67.81 ± 4.61), (74.18 ± 5.21), t = 11.324, 11.038, both P < 0.001). Total satisfaction rate in the observation group was significantly higher than that in the control group [95.00% (57/60) vs. 81.67% (49/60), χ2 = 5.175, P < 0.05]. Conclusion:Cone beam computed tomography measurement of maxillary anterior teeth can help increase implant success rate and patient satisfaction.
