Background Idiom skills are essential for children to access age-appropriate media, curriculum resources and teaching. Children with developmental language disorder (DLD) require support to develop the ability to understand and define idioms. However, research investigating one-to-one and classroom-based idiom skill intervention for children with DLD is limited. Aims To investigate the effectiveness of one-to-one speech and language therapist (SLT) and classroom-based interventions to develop and maintain progress of the idiom skills of 9-16-year-olds with DLD. Methods & Procedures Forty-nine 9-16-year-olds from a specialist school for children with DLD received 20 intervention sessions to develop idiom skills during two school terms. Following a baseline period, 24 participants (aged 11-16) received ten 30-min one-to-one SLT intervention sessions once per week for the first term and classroom-based intervention for the second term. A total of 25 participants (aged 9-16) received the same intervention in the reverse order. Classroom-based intervention was delivered collaboratively by English teachers and SLTs during English lessons. All participants were assessed on their ability to identify, interpret, explain and use idioms 3 months before, directly before and after each intervention and 3 months post-intervention, using a bespoke assessment including 48 idioms randomly assigned to three sets: one-to-one intervention, classroom-based intervention and control idioms. Outcomes & Results Participants made significantly more progress during the intervention blocks than during the baseline period (block 1: d = 1.91; block 2: d = 1.01) and post-intervention levels were maintained 3 months post-intervention. Idiom skills showed significant progress when targeted through both one-to-one (d = 2.18) and classroom-based intervention (d = 0.91) but one-to-one intervention was significantly more effective than classroom-based intervention (d = 0.63). Examination of the specific idiom skills targeted revealed that although idiom identification and interpretation skills did not progress significantly more during intervention blocks than the baseline period, idiom explanation (block 1: d = 1.02; block 2: d = 0.97); and use did (block 1: d = 0.94; block 2: d = 0.81). One-to-one intervention was more effective than classroom-based intervention for developing idiom explanation (d = 1.32) and use (d = 0.65). Progress on control items was not significantly different during intervention blocks than during the baseline period overall or for any of the individual idiom skills. Conclusions & Implications Both one-to-one SLT and classroom-based intervention are effective (although one-to-one is more effective) for teaching and maintaining idiom skills, particularly explanation and use. This means that SLTs and English teachers can help children to develop idiom skills which may enable better access to the curriculum and popular media.

Purpose: To elucidate the potential role of long non-coding RNA (lncRNA) DUXAP8 in the malignant progression of colorectal cancer (CRC) and its possible molecular mechanism. Methods: The expression level of lncRNA DUXAP8 in CRC tissues and matched paracancerous tissues was detected by quantitative real-time polymerase chain reaction (qRT-PCR). Meanwhile, its level in CRC patients with different tumor sizes and tumor grades was determined. The regulatory effects of DUXAP8 on the behaviors of CRC cells were evaluated by cell counting kit-8 (CCK-8), 5-Ethynyl-2'-deoxyuridine (EdU) and Transwell assay. The interaction between LSD1, EZH2 and DUXAP8 was evaluated by RNA-protein interactions and RIP assay. Linear regression analyses were conducted to examine the correlation between DUXAP8 and LSD1, EZH2. Results: LncRNA DUXAP8 was upregulated in CRC tissues and cell lines. Its level remained higher in CRC with larger tumor size or higher tumor grade. Knockdown of DUXAP8 suppressed the proliferative, migratory and invasive abilities of DLD-1 and SW480 cells. Both RF classifier and SVM classifier predicted the pronounced accuracies of LSD1 and EZH2. RIP assay further demonstrated the interaction between DUXAP8 and LSD1, EZH2. Knockdown of LSD1 or EZH2 could attenuate the proliferative rate of CRC cells. Moreover, the mRNA levels of LSD1 and EZH2 were positively correlated with DUXAP8 in CRC. Conclusions: LncRNA DUXAP8 accelerates the malignant progression of CRC via positively regulating EZH2 and LSD1.
