Objectives: To analyze and summarize the clinicopathological features, risk factors for cervical nodal metastasis, and prognostic factors of malignant sublingual gland tumors (MSLGT). Methods: Patients diagnosed with MSLGT were retrospectively reviewed from January 2005 to December 2017 at Shanghai Ninth Hospital. The clinicopathological features were summarized, and the correlations between clinicopathological parameters, cervical nodal metastasis, and local–regional recurrence were evaluated using the Chi‐square test. Kaplan–Meier method and Cox regression analysis were performed to assess the survival and independent prognostic factors. Results: Seventy‐nine patients were included, and the 5‐year overall survival and disease‐free survival rates was 85.7% and 71.7%, respectively. Gender and clinical tumor stage were risk factors for cervical nodal metastasis. Tumor size and pathological lymph node (LN) stage were independent prognostic factors for adenoid cystic carcinoma (ACC) of the sublingual gland; while age, pathological LN stage, and distant metastasis were prognostic factors for patients with non‐ACC of the sublingual gland. Patients with higher clinical stage were more likely to undergo tumor recurrence. Conclusions: Malignant sublingual gland tumors are rare, and neck dissection should be performed in male MSLGT patients with higher clinical stage. Among patients with both ACC and non‐ACC MSLGT patients, pN+ indicate a poor prognosis. [ABSTRACT FROM AUTHOR]

Objectives: To analyze the clinicopathological features, locoregional or distant metastasis, and prognosis of adenoid cystic carcinoma of submandibular gland (SMG‐AdCC). Methods: The clinicopathological data of 80 patients with SMG‐AdCC from January 2005 to December 2017 were analyzed retrospectively, and the relationships between different parameters of SMG‐AdCC and its locoregional or distant metastasis or prognosis were analyzed. Results: As of December 2019, 41 patients (51.25%) were tumor‐free, while 20 patients were found to be living with tumors. The locoregional metastasis rate of grade II‐III SMG‐AdCC were found to be significantly higher than that of grade I. The five‐year DFS and OS rates were 70.8% and 87.1%, respectively. Univariate analysis showed that clinical size, extraglandular extension, pathological grade, pathological node (pN) status, and perineural invasion were correlated with DFS. Multivariate Cox regression analysis showed that pathological grade and extraglandular extension were independent prognostic factors for DFS; pN status and extraglandular extension were independent prognostic factors impacting OS. Conclusion: The pathological grade is a risk factor for locoregional metastasis of SMG‐AdCC. Pathological grade, pN status, and status of extraglandular extension are independent prognostic factors for DFS/OS in SMG‐AdCC patients. [ABSTRACT FROM AUTHOR]

Assembly of two-dimensional (2D) metal–organic layers (MOLs) based on the hard and soft acid–base theorem represents an exquisite strategy for the construction of photocatalytic platforms in virtue of the highly exposed active sites, much improved mass transport, and greatly elevated stability. Herein, nanocages composed of MOLs are produced for the first time through a cosolvent approach utilizing zirconium-based UiO-66-(OH)2 as the structural precursor. To endow the catalytic activity for CO2 conversion, single atomic Co2+ sites are appended to the Zr-oxo nodes of the MOL cages, demonstrating a remarkable CO yield of 7.74 mmol·g−1·h−1 and operational stability of 97.1% product retention after five repeated cycles. Such an outstanding photocatalytic performance is mainly attributed to the unique nanocage morphology comprising enormous 2D nanosheets for augmented Co2+ exposure and the abundant surface hydroxyl groups for local CO2 enrichment. This work underlines the tailoring of both metal–organic framework (MOF) morphology and functionality to boost the turnover rate of photocatalytic CO2 reduction reaction (CO2RR).
