BackgroundRumination can play a certain degree role of psychological adjustment in cancer patients. Previous studies have focused on studying the level of rumination in a single type of cancer patient， but there is a lack of comprehensive investigation and influencing factor research on rumination levels in different types of cancer patients. ObjectiveTo explore the level of rumination and its influencing factors among middle-advanced cancer inpatients， so as to provide certain guidance for targeted psychological care in clinical practice. MethodsFrom January 2021 to December 2022， a systematic sampling technique was used to recruit 346 patients with TNM stage III or above tumors hospitalized in Nuclear Industry 416 Hospital， Chengdu Sixth People's Hospital and the First People's Hospital of Yibin. All individuals were assessed using Perceived Social Support Scale （PSSS） and the Chinese version of Event-Related Ruminant Inventory （C-ERRI）， and Logistic regression analysis was utilized to identify the influencing factors of rumination. ResultsIn terms of C-ERRI， patients scored （15.59±5.61） on intrusive rumination and （14.59±5.43） on deliberate rumination. Education levels of junior high school/high school/vocational training school （OR=0.817， P<0.01） and junior college and above （OR=0.579， P<0.05） were the protective factors of intrusive rumination， whereas annual personal incomes of <10 000 yuan （OR=4.918， P<0.01） or 10 000~50 000 yuan （OR=2.076， P<0.01） and low （OR=6.882， P<0.01） or middle （OR=3.114， P<0.01） level of social support were the risk factors of intrusive rumination. For deliberate rumination， education levels of junior high school/high school/vocational training school （OR=0.574， P<0.01） and junior college and above （OR=0.449， P<0.05） were the protective factors， and low （OR=1.391， P<0.01） or middle （OR=1.161， P<0.05） levels of social support were the risk factors. ConclusionThe level of intrusive rumination of inpatients with middle-advanced cancer is related to education level， economic status and social support， furthermore， the level of deliberate rumination is related to the educational level and social support. ［Funded by Medical Research Project of Chengdu Health Commission （ number， 2020119）］

  Objective  To summarize the clinical manifestations, pathological features and gene mutation diversity of Blau syndrome/early-onset sarcoidosis.  Methods  We collected general data, clinical manifestations, and auxiliary examination results from 8 patients who were diagnosed of Blau syndrome/early-onset sarcoidosis and treated in our hospital from January 2011 to December 2022, and then summarized and analyzed their characteristics and diversity.  Results  Among the 8 patients, 4 were males and 4 were females. The onset age was 3 to 8 months old. Rash was the first symptom in 7 patients(87.5%). 6 patients(75.0%) had papules and erythema.3 cases(37.5%) had arthritis. 2 cases(25.0%) had uveitis and other eye inflammation. 4 cases (50.0%) also showed intermittent fever. 3 cases (37.5%) showed symptoms in nerve and respiratory system, and hypertension respectively. The skin histopathology of 8 patients showed non-caseous granuloma formation. In laboratory detection, CRP and TNF-α were significantly increased before treatment, while IL-6, IL-8, TNF-α and IL-2 receptor(IL-2R) were significantly decreased in 5 patients after glucocorticoid therapy. The results of genetic testing showed that 4 of the 7 patients had p.R334W(c.1000C > T) mutation, 1 had p.H313R(c.938A > G) and p.R471C(c.1411C > T)double mutation, and 1 had p.476_477del (c.1427_1429delcct).  Conclusions  Blau syndrome/early-onset sarcoidosis has significant features in clinical manifestations, histopathology and gene mutation, but it also has diversity.
