Objective To analyze the forkhead box L2 neighbor (FOXL2NB) expression in colorectal cancer (CRC) and its potential clinical significance, and to explore the role of FOXL2NB in CRC cells. Methods Real time qPCR and Western blot were used to analyze the expression of FOXL2NB in CRC tissues and cells. Transwell and CCK-8 assay were used to investigate the effect of FOXL2NB on the proliferation and migration in SW620 cell line. Kaplan-Meier and multivariate Cox regression analysis were used to evaluate the prognostic significance of FOXL2NB in CRC patients. CIBERSORT R package was used to calculate the correlation between FOXL2NB expression and immune cell infiltration in CRC tissues. limma R package was used to calculate the genes that significantly correlated with FOXL2NB expression. Results The mRNA and protein levels of FOXL2NB were significantly increased in CRC cell lines and tissues (P＜ 0.05). High level of FOXL2NB was associated with shorter overall survival and progression free survival in CRC patients (P＜ 0.05), which could be used as an independent risk factor for CRC prognosis (HR=2.27, 95% CI=1.78-2.9, P＜ 0.001). FOXL2NB knockdown inhibited the migration and proliferation of CRC cells. Cell adhesion molecules and tumor immune-related pathways were significantly enriched in CRC with high FOXL2NB expression, CD8+ T cells and activated dendritic cells were significantly increased, while M0 macrophages were significantly decreased. FOXL2NB expression was positively correlated with SCRT2, MGAT5B, SELENOV, FOXB1, KCNA4, LRRC14B and SLC32A1 genes. Conclusions FOXL2NB is highly expressed in CRC and potentially predicts poor prognosis. FOXL2NB might promote CRC cell proliferation and migration.

Background: To examine the cardiovascular disease (CVD) risks associated with metabolic dysfunction‐associated steatotic liver disease (MASLD) and different numbers of cardiometabolic risk factors (CMRFs) in patients with inflammatory bowel disease (IBD) based on a long‐term prospective cohort. Methods: Prevalent IBD patients at baseline who were free of CVD, cancer, alcoholic liver disease, cancer and hepatitis B/C virus seropositive were included (N = 4204). MASLD, MASLD subtypes [pure MASLD, MASLD with increased alcohol intake (MetALD)], lean/non‐lean MASLD and CMRFs at baseline were defined according to the latest criteria proposed by AASLD and EASL. The primary outcome was incident CVD, including ischaemic heart disease (IHD), heart failure (HF) and stroke. Multivariable Cox proportional hazard models were used to estimate the relationship. Results: Overall, 1528 (36.4%) were diagnosed with MASLD at baseline. During a median of 13.1‐year follow‐up, 503 incident CVDs were identified. Compared with IBD‐only, IBD‐MASLD patients had an increased risk of CVD (HR = 1.77, 95%CI: 1.26–2.49), especially in those with MetALD (HR = 2.34, 1.34–4.11) and lean MASLD (HR = 2.30, 1.13–4.66). As the number of CMRFs increased, the risks of CVD were significantly increased (ptrend <0.001), with a 116% and 92% excess risk in MASLD with 3 CMRFs (HR = 2.16, 1.48–3.15) and ≥4 CMRFs (HR = 1.92, 1.27–2.91). Similar excess risk of incident IHD and HF was observed in IBD‐MASLD, either pure MASLD or MetALD, as well as lean/non‐lean MASLD. Conclusions: MASLD is associated with increased CVD risk in IBD patients, with greater risk as number of CMRFs increased and evidently higher risk in MetALD and lean MASLD patients.

Fast‐switching high‐efficiency liquid crystal grating is a key component in holographic true‐3D display systems. In this paper, we present our research and development of a 10.7" liquid crystal grating with 2‐3 millisecond switching time, close‐to‐ideal deflection efficiency, and >100 polarization contrast. The high performance is achieved by optimizing the design and process of the liquid crystal grating panel as well as the optical module stack. Several key design principles are analyzed and verified. Based on the developed liquid crystal grating, a 10.4" full‐color naked‐eye holographic 3D display prototype is successfully realized. [ABSTRACT FROM AUTHOR]

Polymer-dispersed liquid crystal (PDLC) films are widely used in intelligent opto-electronic field owing to their electrically switchable properties. Previous studies have focused on the improvement of electro-optical properties of PDLC film in visible light bands; yet, the application of PDLC in other bands has few research. In this paper, vinylferrocene was introduced into PDLC films containing polyhedral oligomeric silsesquioxane (POSS) to improve UV-shielding properties. Scanning electron microscopy (SEM) studies revealed that vinylferrocene was uniformly dispersed in the polymer network. The structure could improve the electro-optical properties of PDLC film. The effect of temperature on PDLC film was studied. When the temperature reached 35°C, the PDLC composite film polymer network had better electro-optical properties. The PDLC composite films can effectively shield 86.73% UV light at on-state and 93.37% at off-state. The unique UV-shielding properties make this PDLC film a great application potential in smart windows. This PDLC combined with POSS and vinylferrocene film also exhibits large-area processability, which can further expand its application. [ABSTRACT FROM AUTHOR]
