Neuroendocrine tumors of the epiglottis were extremely rare. Patients normally had no obvious symptoms and signs of early stage. Epiglottis lingual except (without) tubercle of epiglottis, and hyperplastic mass were observed by using laryngoscopy and also confirmed by biopsy and immunohistochemistry. Immunohis- tochemical studies showed that Syn, a broad spectrum endocrine marker, and CgA, a specific marker of endocrine tumor, were both positive. Which is consistent with the diagnosis of neuroendocrine carcinoma.

Objective To examine the effect of epigallocatechin gallate (EGCG) at different concentration (0,10,25, 50 and 100μmol/L ) on proliferation rate and apoptosis of nasopharyngeal carcinoma cell line C666-1 in vitro, and elucidate the role of silent information regulator 1 (SIRT1). Methods The proliferation rate in vitro of C666-1 cells stimulated by EGCG at increasing concentrations (0,10,25,50,and 100 μmol/L)for 24 h or at concentration of 50μmol/L for 0,6,12 h and 24 h were detected by cell counting kit-8 (CCK-8) assays. Cell were treated with EGCG at concentration of 0,25, 50 and 100 μmol/L for 24 h, cell apoptosis was anylysed by TUNEL assay and expression levels of SIRT1 protein was detected by western blotting. Results EGCG suppressed cell proliferation of C666-1 cell line in a concentration-dependent manner at concentration of 0 ,10,25,50,and 100μmol/L, and in a time-dependently when treated with 50 μmol/L for 12 to 24 h(P<0.05). After treated for 24 h with different concentration of EGCG at 0、25、50、100 μmol/L, cell apoptosis increased at concentration of 50 to 100μmol/L and expression of SIRT1 decreased in a concentration-dependently (P<0.05). Conclusion EGCG induced cell apoptosis of C666-1 cells by down-regulating SIRT1 expression.

BACKGROUND:Bone cement used in the vertebroplasty treatment of osteoporotic vertebral compression fractures is nonabsorbable and has stronger intensity than normal bone tissue, which can cause further fractures of adjacent segments. OBJECTIVE:To investigate the short-term effect of vertebroplasty with artificial bone in the treatment of osteoporotic thoracolumbar fractures. METHODS:A total of 21 patients with osteoporotic vertebral compression fractures were enrol ed, including 7 males and 14 females, aged 61-89 years old. Al the patients were subjected to vertebroplasty with calcium sulfate injection. Visual analog scale and Oswestry Disability Index assessment were used before and at 0, 24, 48 weeks after treatment;meanwhile, X-ray and CT were used to observe the fil ing and leakage of artificial bone. RESULTS AND CONCLUSION:After treatment, al the patients showed improvements in the scores of visual analog scale and Oswestry Disability Index (P<0.01). X-rays and CT scans showed that there were three cases of leakage but without spinal cord and nerve compressions. After 3 months, most of the artificial bone was absorbed. These findings indicate that vertebroplasty with artificial bone can ease pain and improve living conditions of patients with osteoporotic vertebral compression fractures.
