A multidrug-resistant clone of human oral epidermoid carcinoma KB cells was isolated by stepwise selection on exposure to increasing doses of vincristine. The final clone, KBv200, obtained after ethylmethane sulfonate mutagenesis showed 156-fold higher resistance to vincristine than KB cells. The cells were also cross-resistant to paclitaxel and adriamycin.(More)
OBJECTIVE To study the radiosensitizing effect of resveratrol on human hypo pharyngeal squamous cell carcinoma (FaDu) cells in nude mice. METHODS Forty-three nude mice bearing FaDu cell xenografts were randomized into control group, radiotherapy (12 Gy) group, resveratrol treatment (50 mg/kg) group, and radiotherapy plus resveratrol treatment group. After(More)
The present study aimed to investigate the effect of A disintegrin and metalloproteinase 10 (ADAM10) gene silencing on the proliferation, migration and invasion of the human tongue squamous cell carcinoma cell line TCA8113. RNA interference was used to knock down the expression of ADAM10 in the TCA8113 cell line and the proliferation, migration and invasive(More)
The aim of this study was to investigate the effect of microRNA (miR)-145 on the proliferation, migration and invasion of the human oral cancer line, TCA8113. Expression levels of miR-145 in TCA8113 cells were detected by quantitative PCR. miR-145 was transfected into human TCA8113 oral cancer cells and the proliferation, migration and invasion abilities of(More)
OBJECTIVE To explore the reversal effect and potential mechanism of resveratrol on multidrug resistance of human oral epidermoid carcinoma KBv200 cells. METHODS MTT assay was used to investigate reversal index of resveratrol to vincristine, adriamycin and paclitaxel. Cell apoptosis were measured by flow cytometry. RT-PCR and Western blot were used to(More)
Prolonged QT interval is usually seen on routine electrocardiogram (ECG), but in some patients it may only be seen immediately before the evolution of torsades de pointes (Tdp). To unmask the potential risk of Tdp in a patient with normal or borderline prolongation of QTc interval and recurrent syncope, dobutamine was given intravenously at a rate of 20(More)
OBJECTIVE To study the radiosensitizing effect of resveratrol on hypopharyngeal carcinoma cell line FADU in vitro. METHODS Hypopharyngeal carcinoma cell line FADU was cultured in in vitro DMEM. Its inhibition on cell proliferation was detected using cytotoxicity test (MTT assay). The cell survival curve was drawn using clone formation to obtain sensitive(More)
The measurement of the size of lesions in follow-up CT examinations of cancer patients is important to evaluate the success of treatment. This paper presents an automatic algorithm for identifying and segmenting lymph nodes in CT images across longitudinal time points. Firstly, a two-step image registration method is proposed to locate the lymph nodes(More)
OBJECTIVE To discuss the application of frontal sinus optical probe in endoscopic frontal sinus surgery. METHOD The clinical data of 58 adult patients (86 sides) suffering from chronic frontal sinusitis were analyzed retrospectively. The patients received endoscopic frontal sinus surgery with frontal sinus optical probe because of difficulty in confirming(More)
OBJECTIVE In order to explore the management of peri-operation and the therapeutic effect in the surgical treatment of hyperthyroidism. METHODS Fifty five cases of hyperthyroidism were undergone near-total thyroidectomy, during the operation recurrent laryngeal nerve was exposed, and the parathyroid was found with microscope when necessary. The third rank(More)
