Abstract	This study aimed to comprehensively evaluate the effect of dual-cured resin luting agents with different initiator systems on the color stability of glass ceramic restorations by simulating various clinical glass ceramic restorations. Three commonly used shades from each of the two dual-cured resin luting agents with an amine-initiation system or without it were studied. The individual specimens had different translucency and thickness and were artificially aged using a xenon light aging machine. The color was measured before and after aging using a digital spectrophotometer with the difference calculated and analyzed statistically. As results, the amine-free dual-cured resin luting agents were more color stable than those using amine-initiation systems for both uncovered and bonding groups. The translucency and thickness of the ceramic, and shade and type of the resin luting agent significantly affected the color stability of glass ceramic restorations.

Abstract	Objectives: Dental luting cements are widely used to bond indirect restorations to teeth. Microcracks often lead to cement failures. The objectives of this study were to develop the first self-healing luting cement, and investigate dentin bond strength, mechanical properties, crack-healing, and self-healing durability in water-aging for 6 months. Methods: Microcapsules of poly(urea-formaldehyde) (PUF) shells with triethylene glycol dimethacrylate (TEGDMA) as healing liquid were synthesized. Cement contained bisphenol A glycidyl dimethacrylate, TEGDMA, 4-methacryloyloxyethyl trimellitic and glass fillers. Microcapsules were added at 0%, 2.5%, 5%, 7.5%, 8.5%, 9.5% and 10%. Dentin shear bond strength was measured using extracted human teeth. Flexural strength and elastic modulus were measured. Single edge V-notched beams were used to measure fracture toughness (K Results: Adding 7.5% microcapsules into cement achieved effective self-healing, without adverse effects on dentin bond strength and virgin mechanical properties (p>0.1). Excellent self-healing of 68%-77% recovery was obtained. Six months of water-aging did not decrease the self-healing efficiency, compared to 1 d (p>0.1), indicating that the self-healing property did not degrade in water-aging. Conclusions: A self-healing dental luting cement was developed for the first time. It contained fine microcapsules and exhibited an excellent self-healing efficiency, even after being immersed in water for 6 months. Clinical significance: The self-healing cement is promising for cementing crowns and bridges and other adhesive cement applications, to heal cracks and increase restoration longevity.

Abstract	Acquired cystic disease-associated renal cell carcinoma (ACD-RCC) is an extremely rare kidney tumor seen mainly in patients with end-stage renal disease. Currently, there are few reports on this type of tumor. We describe the case of a 58-year-old man who had been receiving peritoneal dialysis for more than nine years due to chronic renal insufficiency and uremia. One year after undergoing left renal clear cell renal cell carcinoma resection, a space-occupying lesion was found in the right kidney for which he underwent right nephrectomy. The histopathology of this tumor showed solid or tubular cell arrangements, with some areas of cyst formation. Vacuoles of varying sizes were present in the cytoplasm, and varying amounts of calcium oxalate crystals were found in the tumor cells or interstitium. The pathological diagnosis was ACD-RCC. Next-generation sequencing detected mutations in the PTCH1, MTOR, FAT1, SOS1, RECQL4, and CDC73 genes in the right renal tumor. This is a rare case of a patient with ACD-RCC in the right kidney and clear cell renal cell carcinoma in the left kidney. The findings suggest that mutations in PTCH1 associated with ACD-RCC may have acted as oncogenic drivers for the development of ACKD-RCC, together with providing insight into mechanisms underlying ACD-RCC development, as well as diagnostic and treatment options.

Abstract	Objective: To evaluate the prognostic value of CA9 in predicting postoperative recurrence， metastasis or survival in patients with clear cell renal cell carcinoma(ccRCC). Methods: The clinical pathological data from 231 patients with ccRCC who underwent radical or partial nephrectomy from January 1, 2017 to December 31, 2020 in Ruijin Hospital,Shanghai Jiao Tong University were retrospectively analyzed. The patients were followed up for the overall survival (OS),disease-free survival (DFS),and tumor recurrence or metastasis. All pathological sections and wax blocks of tumor issue were collected to make tissue microarray, and immunohistochemical analysis of tissue microarray was performed using CA9 polyclonal antibody. SPSS statistical software multivariate Cox and Kaplan-Meier were used to evaluate the correlation of CA9 expression with clinicopathological features, OS and DFS. Results: Of the 231 ccRCC patients had a median follow-up of 37 months (13-54 months). It revealed that postoperative recurrence and/or metastasis occurred in 38 cases, inclu-ding 6 cases with both recurrence and metastasis, 3 cases with only recurrence, 29 cases with only metastasis, and 8 deaths. Among 231 patients, CA9 positive expression rate was 94%(217/231), of which 153 (66%) were with cells stained with CA9 ≥85% and 78 (34%) were stained with CA9 <85%. Chi-square analysis showed that the expression of CA9 was not only correlated with T stage, ISUP nuclear grade, sarcomatoid or rhabdomyoid differentiation, necrosis, capsule invasion, vascular infiltration, but also correlated with tumor recurrence, metastasis and survival status. There was no relationship between CA9 expression and age, sex and tumor location (P>0.05). Univariate Kaplan-Meier analysis and multiva-riate Cox analysis showed that low expression of CA9 (<85%) was a poor prognostic factor for postoperative overall survival (OS) and disease-free survival (DFS) in patients with ccRCC, with hazard ratios of 6.211 (P=0.002) and 8.980 (P<0.001), respectively. ...

Abstract	Among primary bone cancers, osteosarcoma is the most common, peaking between the ages of a child’s rapid bone growth and adolescence. The diagnosis of osteosarcoma requires observing the radiological appearance of the infected bones. A common approach is MRI, but the manual diagnosis of MRI images is prone to observer bias and inaccuracy and is rather time consuming. The MRI images of osteosarcoma contain semantic messages in several different resolutions, which are often ignored by current segmentation techniques, leading to low generalizability and accuracy. In the meantime, the boundaries between osteosarcoma and bones or other tissues are sometimes too ambiguous to separate, making it a challenging job for inexperienced doctors to draw a line between them. In this paper, we propose using a multiscale residual fusion network to handle the MRI images. We placed a novel subnetwork after the encoders to exchange information between the feature maps of different resolutions, to fuse the information they contain. The outputs are then directed to both the decoders and a shape flow block, used for improving the spatial accuracy of the segmentation map. We tested over 80,000 osteosarcoma MRI images from the PET-CT center of a well-known hospital in China. Our approach can significantly improve the effectiveness of the semantic segmentation of osteosarcoma images. Our method has higher F1, DSC, and IOU compared with other models while maintaining the number of parameters and FLOPS.

Abstract	Guided by attention restoration theory and stimulus-organism-response (S-O-R) theory, we developed an integrated model to investigate the impact of perceived environmental restoration on forest park visitors' pro-environmental behavior through the mediation of place attachment. We further tested the moderating role of eco-centrism to provide theoretical and practical implications for the sustainability of tourism destinations and positive human-nature interactions. Using a sample of 504 visitors to a national forest park in China, our study indicated all three dimensions of environmental restorative perception (compatibility, extent, and away) positively influenced place attachment. Place attachment promoted pro-environmental behavior. Place attachment was an important mediator of the relationship between environmental restorative perceptions (compatibility, extent, and away) and pro-environmental behavior. Eco-centrism has no moderating effect.
