Correlation of survivin, p53 and Ki-67 in laryngeal cancer Hep-2 cell proliferation and invasion

Objective:To investigate the mechanism of survivin, p53 and Ki-67 on Hep-2 human laryngeal cancer endothelial cell proliferation and invasion.Methods:Laryngeal squamous cell carcinoma and paracancerous normal tissues were collected, total RNA was extracted from tissues,survivin,p53and Ki-67gene mRNA expression levels in laryngeal cancer and the adjacent tissues were detected by Real-time PCR. Human laryngeal cancer Hep-2 epithelial cells were selected,survivin gene was overexpressed, and cell proliferation was detected by MTT.p53 andKi-67gene expression changes in overexpressedsurvivin gene were detected by Western blot. Changes in Hep-2 cell invasive ability were studied whensurvivin was overexpressed as detected by Transwell invasion assay.Results: In the adjacent tissues, survivin,p53andKi-67 gene relative expression levels were 1.72 ± 0.9, 13.7 ± 5.7 and 5.7 ± 1.3, respectively; while in cancer tissues, gene relative expression levels were 53.7 ± 8.3, 66.7 ± 5.2 and 61.0 ± 3.1, respectively, which was significantly increased. As detected by MTT, relative cell survival rate within 12 h ofsurvivinoverexpression were: load control group, (88.5±1.6)%; overexpressed group, (90.3±1.9)%. Transwell invasion assay results indicated that overexpressedsurvivincould significantly increase the relative survival rate of cells. Conclusions:Expressions ofp53,Ki67 and survivin are increased in cancer; and there is a positive correlation betweensurvivin, p53andKi67 expressions in laryngeal carcinoma.

Expressions and correlations of Survivin, Ki67 and p53 in laryngeal squmous cell carcinoma / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the expression of Survivin, p53 and Ki67 in laryngeal carcinoma and the relation with clinical data.@*METHOD@#Immunohistochemical staining (SP) was used to detect expression of Survivin, p53 and Ki67 of 64 cases with laryngeal carcinoma, 26 cases with precancerosis, 34 cases with vocal polyps.@*RESULT@#The positive expression rates of Survivin, p53 and Ki67 were 59.4%, 68.8%, 65.6% respectively in laryngeal carcinoma, which were significantly higher than those in precancerosis and vocal polyps (P 0.05). The expression of Survivin, Ki-67 and p53 was positively correlated (r = 0.607, 0.541, 0.648, P < 0.01) in laryngeal carcinoma.@*CONCLUSION@#Survivin, p53 and Ki-67 may play an important role in the carcinogenesis and progress of laryngeal carcinoma. They may play synergetic roles in the process of carcinogenesis of laryngeal carcinoma.

An objective evaluation of nasal airway obstruction by enlarged adenoids in children / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the clinical application value of nasal airway obstruction objectively and quantificationally by acoustic rhinometry (AR) in children with adenoid hypertrophy.@*METHOD@#Thirty patients with adenoid hypertrophy were examined with AR and questionnaire at preoperative and eight weeks after surgery. The values of AR were compared with those of 27 normal controls.@*RESULT@#There were significant differences between preoperative and postoperative in NAR and NPV (P 0.05); There were significant differences in NAR, NPV, MCSA between the patient group and the control group (P 0.05); There was negative correlation between MCSA and symptom scores (r = -0. 519, P 0.05).@*CONCLUSION@#Acoustic rhinometry was an objective and quantitative method for evaluating nasal airway in children with adenoid hypertrophy. In interpretation the relationships of the results of acoustic rhinometry reflection measurements and subjective symptoms, MCSA should be the main reference.

Management of advanced head and neck cancer with intertissue injection of 32P radioisotope / 中国耳鼻咽喉头颈外科

OBJECTIVE To observe the effect of 32P intertissue injection on advanced head and neck cancer. METHODS Eight patients with advanced head and neck cancer were treated with 32P injection into the tumors according to the size of the cancer as determined by CT scan. RESULTS Local tumors were controlled evidently and the pain of the patients were alleviated. The survival periods of the 8 cases ranged from 3 to 18 months (average 14.2 months). CONCLUSION 32P intertissue injection offer an useful method for patients with advanced head and neck cancer .
