Manometric evaluation of oral function with a hand-held balloon probe

Tongue pressure measured with a disposable hand-held balloon probe has been used for assessing tongue function; however, no diagnostic standard for assessing other oral functions exists currently. In this study, to develop a method for multifactorial manometric evaluation of oral functions, 20 men and 20 women (21-32 years of age) were instructed to apply 7-s maximal voluntary muscular effort on a hand-held balloon probe placed against the anterior and lateral parts of the palate, buccal surface of the molars on the habitual chewing side and labial surface of the anterior teeth for measuring anterior and posterior tongue, cheek and lip pressures (LPs), respectively. Intra-session reproducibility was determined by three repeated measurements, and associations between the obtained and the conventional data on oral diadochokinesis were tested. The men exhibited higher values of all the pressure types. Further, both genders showed a positive correlation between anterior and posterior tongue pressures (PTPs) (P < 0·05), but only the women exhibited positive correlations between anterior tongue and cheek pressures, cheek and PTPs, anterior tongue and LPs, and cheek and LPs (P < 0·05). No statistically significant correlation was found between the pressures and the number of syllabic articulations, except between LP and the number of /pa/ articulations in the women (r = 0·524, P < 0·05). In conclusion, the balloon probe method enables objective manometric evaluation of oral functions and could be an effective tool for clinical epidemiological studies and evidence-based decision-making in nursing care.     

舌鳞状细胞癌淋巴管密度与淋巴转移的关系

目的 探讨舌鳞癌组织中淋巴管密度与鳞癌侵袭和转移的关系.方法 选择62例舌鳞癌标本,采用免疫组化SP法检测血管内皮生长因子受体-3(VEGFR-3)和血管内皮生长因子-D(VEGF-D)的表达.结果 62例舌鳞癌标本中有56例标本的VEGFR-3呈阳性表达,但功能性淋巴管主要分布在癌组织周围,癌间质中未见明显的成形淋巴管.舌鳞癌组织中淋巴管密度与舌鳞癌患者年龄、性别无关,而与舌鳞癌病理分级、临床分期和有无淋巴结状况密切相关(P＜0.05).VEGF-D在癌细胞胞质呈阳性表达,且随着VEGF-D表达增强,癌组织周围淋巴管密度亦明显增加.结论 VEGF-D和VEGFR-3途径可促进鳞癌淋巴管新生和淋巴转移.     

超选择动脉插管栓塞化疗晚期舌癌

为探讨新的治疗途径、提高中晚期舌癌治疗效果，自１９９１年～１９９３年，对６例晚期舌癌患者采用经股动脉插管行舌动脉超选择栓塞化疗，取得良好效果。治疗采用患侧舌动脉超选择插管，联合注入顺铂１００～２００ｍｇ，阿霉素１０～２０ｍｇ，丝裂霉素１４～２０ｍｇ等抗癌药局部大计量冲击化疗，并酌情用明胶海绵颗粒部分栓塞舌癌供血动脉。治疗后１周内肿瘤缩小，局部出现坏死、崩解或液化，而全身副作用轻。实践证明，对中晚期舌癌患者于手术前行选择性动脉栓塞化疗是一项值得推广的治疗措施。

目的:了解E-cadherin在舌癌中的表达及其临床意义.方法:采用实时定量PCR检测29例舌鳞癌患者的癌组织和正常组织中E-cadherin mRNA,分析E-cadherin基因表达与临床病理参数的相关性.结果:舌癌组织中E-cadherin mRNA表达水平2.23±1.16(E-cadherin/β-actin),低于正常组织组8.59±2.71,两组间差异有统计学意义(P＜0.01),E-cadherin mRNA水平与临床病理参数之间无相关性(P＞0.05).结论:E-cadherin的表达下降是舌癌发生过程中的重要事件,实时定量PCR检测E-cadherinmRNA的表达对舌癌早期诊断有重要参考价值.     

岩黄连脱氢卡维丁体外抑制Tca8113增殖及对端粒酶活性影响的研究

目的：研究中草药岩黄连脱氢卡维丁（Tetradehydroscoulerine，YHL－1）对人舌鳞状细胞癌Tca8113细胞增殖的抑制作用，及其对端粒酶活性和端粒酶催化亚基（hTERT）表达的影响，探讨其抗癌机制。方法：采用噻唑蓝比色法（MTT法）检测不同浓度的YHL-1对Tca8113细胞增殖的影响，同时以TRAP—ELISA法检测Tca8113细胞端粒酶活性改变情况，并用Western blotting法半定量检测端粒酶hTERT的表达。结果：YHL-1能明显抑制Tca8113细胞增殖，且随时间延长和药物浓度的增高，抑制作用增强。72h时，0．200、0．100、0．050、0．025 g／LYHL-1组细胞增殖抑制率分别为（64．1±1．5）％、（47．3±3．3）％、（35．6±5．0）％、（31．8±5．87）％。72 h时，0．100、0．050 g／L组端粒酶活性和hTERT蛋白含量均低于空白对照组（P〈0．05）。结论：岩黄连脱氢卡维丁可以明显抑制Tca8113细胞的增殖，并显著降低其端粒酶活性及hTERT的表达，这可能是其抗舌癌的机制之一。

Methods and studies of tongue reconstruction

Total and even partial glossectomy could be a major event in the life of a patient. Tongue function is so complicated which makes maintaining normal functions of the tongue such as swallowing and speech and preserving larynx integrity after the surgery is a primary objective of the surgeon. This task is very difficult and the result is not predictable. Recent years, however, there has been interesting developments in microsurgical techniques, and these advancements enable oral and maxillofacial surgeons to achieve better results and improve the quality of their patient′s life. The results even with use of the new technology are still far from perfect. Several reasons may cause variation in the result. Some of them have to do with the patient such as general health and other reasons are due to the method that is used and nature of the defect after the removal of the tumor. This article was undertaken to summarize the various methods and techniques used over the years to restore oral tongue functions after defects.     

VEGFR3在不同临床分期舌癌癌周淋巴管中的表达

目的:研究血管内皮生长因子受体(VEGFR3)在舌癌淋巴转移中的作用,探索舌癌淋巴转移的机制。方法:采用免疫组化和RT-PCR技术,对90例不同分期的舌癌肿瘤进行VEGFR3的检测,与10例正常舌黏膜标本进行对照。采用SAS6.12软件进行单因素方差分析。结果:通过与正常组对照,Ⅰ、Ⅱ、Ⅲ期肿瘤中VEGFR3的表达无显著性差异(P>0.05),Ⅳ期肿瘤中VEGFR3的表达较正常对照组显著升高并具有显著性差异(P<0.05)。肿瘤各组间比较无显著性差异。转移组与非转移组之间也无显著性差异。结论:VEGFR3参与微淋巴管的生成,随着肿瘤的临床分期增高,其表达虽呈缓慢增高趋势,但尚不足以作为判定是否发生淋巴转移的客观指标。
