Compared to the adult group, the elderly patients with deep neck infection had more cases with multiple spaces involvement, complications, surgical interventions, and longer hospital stay. However, the outcome of the elderly group was the same as the adult group. Therefore, the benefits of aggressive management for deep neck infection should not be withheld from patients simply because of the old age.

Background In several human cancers, Krüppel-like factor 5 (KLF5), a zinc finger transcription factor, can contribute to both tumor progression or suppression; however, the precise role of KLF5 in nasopharyngeal carcinoma (NPC) remains poorly understood. In this study, the association between KLF5 and microRNA-145-5p (miR-145-5p) in NPC cells was elucidated. Results Our results showed that KLF5 expression was up-regulated in NPC group compared to normal group. We found that KLF5 exhibited an oncogenic role in NPC cells. The upregulation of miR-145-5p inhibited the proliferation, migration, and invasion of NPC cells. It was observed that miR-145-5p could down-regulate the mRNA and protein expression of KLF5 in NPC cell lines. Additionally, the activity of focal adhesion kinase (FAK), a migration marker, was regulated by miR-145-5p and KLF5 in NPC cells. Conclusions The results of this study indicated that miR-145-5p could repress the proliferation, migration, and invasion of NPC cells via KLF5/FAK regulation, and could be a potential therapeutic target for patients with NPC.

Three new 11,20-epoxybriaranes—fragilides U–W (1–3), as well as two known metabolites, junceellonoid D (4) and junceellin (5), were obtained from the octocoral Junceella fragilis. The structures of briaranes 1–3 were elucidated by spectroscopic methods and briaranes 3 and 5 displayed inhibition effects on inducible nitric oxide synthase (iNOS) release from RAW264.7.

Introduction:The purpose of this study was to analyze the risk factors affecting precancerous lesions, and cancer of oral cavity, and to assess efficacy of visual screening for oral mucosal lesions. Methods:The medical records of patients older than 30 years of age with history of habitual cigarette smoking or betel quid chewing that received screening for oral mucosal lesions between January 2012 and December 2012 were retrospectively reviewed. The patients' age, gender, risk factors, screening findings, and histopathology results of biopsy were included for further analysis.results: A total of 1341 patients were enrolled in this study. There were 1080 males and 261 females ranging from 30 to 96 years of age, with a mean age of 53.9±13.6 years. After screening, 226 (16.9%) were found to be positive of oral lesions. Among these 226 patients, 69 (30.5%) underwent biopsy under local anesthesia, and the histopathology showed malignancy in 13 (5.8%). All of the confirmed malignant cases were squamous cell carcinoma. Among them, 12 received further staging examination and one was lost to follow-up resulting in unknown stage. The early stage oral cavity cancer (stage I and II) accounted for 84.6% (11/13). conclusions:The detection rate of early stage oral cavity cancer in our study was reasonable. Therefore, visual screening for oral cavity cancer is recommended for patients with habitual cigarette smoking or betel quid chewing.

Human krüppel like factor 5 (KLF5) is a zinc finger transcription factor, which contributes to tumor suppression in nasopharyngeal carcinoma (NPC). However, the precise role of KLF5 in NPC remains poorly understood. In the present study, the association between KLF5 and miR-145-5p in NPC cells was elucidated. Cellular proliferation was detected using the WST-1 colorimetric assay. Cellular migration and invasion were studied using wound healing assays and the ECMatrix cell invasion assay, respectively. The protein expression was examined by western blot. Transfection was subsequently performed for generating NPC cells overexpressing KLF5 and miR-145-5p. The upregulation of KLF5 or miR-145-5p inhibited the migration and invasion of NPC cells. It was observed that miR-145-5p could induce the expression of the KLF5 protein in the NPC cell lines. Additionally, the activity of the migration marker, focal adhesion kinase (FAK), was suppressed following the overexpression of miR-145-5p and KLF5 in NPC cells. The results of this study indicated that miR-145-5p may repress the migration and invasion of NPC cells via KLF5, and could be a potential therapeutic target for NPC.
