Abstract
Objective: To investigate the diagnostic value of serum miRNAlet-7a in laryngeal carcinoma and the effect of let-7a on proliferation and apoptosis of laryngeal carcinoma cells. Methods: Real-time quantitative PCR was used to determine the expression level of serum miRNAlet-7a. The miRNA let-7a mimetic was synthesized and transiently transfected into the laryngeal carcinoma Hep-2 cell line by cationic liposome method. The effects of up-regulation of let-7a expression on laryngeal cancer Hep-2 cells were detected by FCM and MTT assays,respectively. The association of let-7a levels with laryngeal cancer and the diagnostic value for laryngeal cancer were analyzed. Measurement data were taken by t test or analysis of variance; Counting data were analyzed by χ(2) test and Fisher exact probability method. The receiver operating characteristic curve was used to analyze the diagnostic value of let-7a for laryngeal cancer. Results: The relative expression of serum let-7a in healthy subjects was significantly higher than that in patients with laryngeal cancer (0.931±0.094) vs (0.380±0.113) (t=26.507,P<0.01). The relative expressions of serum let-7a in patients with laryngeal cancer before and after surgery were (0.380±0.113) vs(0.493±0.164),with significant difference (t=3.848,P<0.01).The relative expression of serum let-7a was related to lymph node metastasis (t=2.946, P<0.01). There was a positive correlation between the relative expression of let-7a in laryngeal carcinoma and that in serum (r=0.466,P=0.003). After transfection of let-7a mimics, Hep-2 cells showed an increased significant increase in the expression of let-7a (P<0.01), proliferation (P<0.01) and apoptosis (P<0.01). ROC curve analysis showed that the best critical value for relative expression of let-7a in the diagnosis of laryngeal carcinoma was 0.557 with a sensitivity of 0.794,a specificity of 0.727,an area under curve(AUC) of 0.859,and a 95%CI of 0.773-0.926. Conclusions: miRNA let-7a can inhibit the proliferation of laryngeal carcinoma Hep-2 cells and promote apoptosis. Serum let-7a is down-regulated in patients with laryngeal cancer and the level of let-7a is related to lymph node metastasis,which would help early diagnosis and postoperative disease monitoring of laryngeal cancer,but further research is needed.

Abstract
Synovial sarcoma of the nasal cavity and sinus are rare,comprise less than 0.1% of all soft tissue malignancies. Synovial sarcoma is a malignant mesenchymal tumor with variable epithelial differentiation, which is defined by the presence of a specific chromosomal translocation that generates SS18-SSX fusion oncogenes. The treatment include surgery,radiotherapy,chemotherapy. As the delicate anatomy of the nasal cavity and sinus limits the ability to obtain wide surgical margins. This maybe the reason why there is a higher local recurrence rate and worse disease-specific survival in head and neck sarcomas compared to other sites.

Abstract
We report a case which involves the maxillary sinus by original of synovial sarcoma of infratemporal fossa and pterygopalatine. A 40-years-old man presented with a history of tumor under the earlobe. It is derived from the synovial sarcoma under temporal fossa after tumor excision. The patient is limited to open his mouth and nasal obstruction. The nasal pathologic examination consider synovial sarcoma.We report the case to improve doctors' comprehension of its pathogenesis,clinical manifestations,teeatment and prognosis.

Abstract
This study investigated the metastatic potential of tongue squamous cell carcinoma (TSCC) cells after X-ray irradiation as well as radiation-induced changes in the biomechanical properties and cytoskeletal structure that are relevant to metastasis. Tca-8113 TSCC cells were X-ray-irradiated at increasing doses (0, 1, 2, or 4 Gy), and 24 h later, migration was evaluated with the wound healing and transwell migration assays, while invasion was assessed with the Matrigel invasion assay. Confocal and atomic force microscopy were used to examine changes in the structure of the actin cytoskeleton and Young's modulus (cell stiffness), respectively. X-ray radiation induced dose-dependent increases in invasive and migratory potentials of cells relative to unirradiated control cells (p < 0.05). The Young's modulus of irradiated cells was decreased by radiation exposure (p < 0.05), which was accompanied by alterations in the integrity and organization of the cytoskeletal network, as evidenced by a decrease in the signal intensity of actin fibers (p < 0.05). X-ray irradiation enhanced migration and invasiveness in Tca-8113 TSCC cells by altering their biomechanical properties and the organization of the actin cytoskeleton. A biomechanics-based analysis can provide an additional platform for assessing tumor response to radiation and optimization of cancer therapies.
