However, there is still no measurement instrument to evaluate the compensatory behavior of ADHD in China. This study aimed to examine the reliability and validity of the Compensatory ADHD Behaviors Scale (CABS) adapted in Chinese and explore ecological characteristics in adults with ADHD using the CABS. Patients and Methods: Data were collected from a sample of 306 adults (Mage = 26.43 years, SD = 5.32; 46.08% male). The original version CABS was translated into Chinese using the forward and backward translation procedures. Participants completed the CABS and questionnaires assessing ADHD symptoms and executive function. We utilized content validity, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and criterion validity to test the validity. Internal consistency and test-retest reliability were employed to test the reliability. Analysis of variance (ANOVA) was employed to compare ADHD subgroups based on gender, ADHD subtype, comorbidities, and medication status, while controlling for demographic variables as covariates. Results: CABS exhibited good construct validity (two factors: present-oriented and future-oriented), content validity (content validity index: 0.98), internal consistency reliability (Cronbach's alpha coefficient: 0.85 to 0.87) and test-retest reliability (intraclass correlation coefficient: 0.59 to 0.88). The results of CFA showed acceptable fitness for each subscale. CABS demonstrated significant associations with inattention symptoms and plan/organizational abilities. Medicated ADHD individuals scored higher on future-oriented effectiveness subscale of CABS than non-medicated (F = 6.106, p = 0.014). Conclusion: The results indicate that the Chinese CABS exhibited good validity and reliability. It can be considered a valid tool for assessing compensatory behaviors in Chinese adults with ADHD. Further research is needed to explore the connection between medication and compensatory behavior. [ABSTRACT FROM AUTHOR]

However, the pathogenesis of DLBCL is still unclear. Materials and Methods: The expression levels of the prolyl isomerase PIN-1 and other related proteins were determined in 73 primary DLBCL patient samples and cell lines by Western blotting (WB) and immunohistochemical (IHC) staining. Cell cycle and apoptosis were evaluated by flow cytometry. Lymphoma cell viability was detected by CCK-8 proliferation assay. Results: High levels of PIN-1 expression were detected in 55% of germinal center B cell (GCB) DLBCL patient samples, whereas such abnormal expression levels were found in only 11% of non-GCB DLBCL patient samples. PIN-1 expression was positively associated with activation of the oncogenic phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) pathway in both GCB DLBCL cell lines and primary patient samples. Depletion of PIN-1 was cytotoxic to GCB DLBCL model cell lines because it led to inhibition of the PI3K/AKT signaling pathway, revealing a GCB DLBCL subgroup that is dependent on this pathway. A PI3K inhibitor was selectively toxic to GCB DLBCL lines expressing high levels of PIN-1. Conclusion: Our study used PIN-1 to identify a new subgroup of GCB DLBCL associated with the PI3K/AKT signaling pathway, and our findings reveal that inhibition of PI3K is a promising therapeutic approach for GCB DLBCL.
