应重视口腔颌面部恶性肿瘤的综合序列治疗

口腔颌面部恶性肿瘤约占全身恶性肿瘤的3％，虽然所占比例不高，但l大l其解剖部位特殊．涉及美观和重要的生理功能，冈此对患者机体和心理的影响不容忽视。早期（Ⅰ、Ⅱ期）口腔颌面部恶性肿瘤无论采用手术和（或）放射治疗，均能取得良好效果。但遗憾的是，大多数患者就诊时，已属局部一区域晚期（Ⅲ、Ⅳ期）。由于受到局部解剖和维持功能的限制，单纯通过扩大手术切除范围和改进现有手术技术，除能改善患者生存质量外，已无法提高此类患者的生存率，延长其生存时间。     

Teratoma tongue: Case report and review of literature

Teratomas are true neoplasms composed of tissues from all three germinal layers and may exhibit variable levels of maturity. They have an unknown origin and eccentric microscopic appearance. Teratomas arising from the oral cavity are rare in the newborn; only 22 cases have been reported in the literature. We describe a female neonate with an oral teratoma originating from the tongue that was successfully treated with surgery.     

保肾口服液影响IgA肾病小鼠T细胞增殖及分泌IL-2的实验研究

观察保肾口服液对IgA肾病小鼠T细胞^3H-TdR掺入及其分泌IL-2水平的影响，结果表明低、中、高3种浓度的保肾口服液均能显著促进IgA肾病小鼠的自发性和ConA刺激的T细胞^3H-TdR掺入，促进T细胞合成，分泌IL-2，提前给药作用相同。提示保肾口服液有显著增强IgA肾病小鼠细胞免疫功能的作用。     

补肾抗衰口服液对大鼠衰老模型免疫器官影响的实验研究

研究补肾抗衰口服液对大鼠衰老模型免疫器官胸腺和脾脏的影响.结果显示,模型组大鼠胸腺和脾脏重量减轻,胸腺重/体重比值、脾重/体重比值减小,胸腺组织学观察,显示萎缩改变;药物组大鼠胸腺和脾脏重量、胸腺重/体重、脾重/体重比值接近正常对照组,胸腺组织学观察,未显示萎缩改变.本研究结果表明,补肾抗衰口服液能延缓胸腺和脾脏萎缩,保护机体的正常免疫功能,提示该药有抗衰老的作用.     

正常人口腔粘膜不同部位表面感觉的测试

目的 建立正常人口腔粘膜不同部位表面感觉的正常参考值，并测试各年龄组感觉值是否存在差异。方法 利用动静两点辨别觉试验，测试90例健康人口腔粘膜不同部位的表面感觉。结果 舌尖感觉功能最好，其次为舌背、舌腹、颊粘膜、口底和硬腭。健康人的口腔粘膜不同部位的表面感觉随着年龄增长有显著性变化。结论 口腔粘膜不同部位感觉辨别力存在差异，健康人口底、舌腹、舌背、颊和硬腭粘膜感觉功能有增龄性变化。

überlebensverbesserung eines unizentrischen Gesamtkollektivs aus 20 Jahren

PURPOSE: The development of overall survival of a DOSAK (German-Austrian-Swiss Cooperative Group on tumours of the maxillofacial region) clinic's overall population comprising a time period of more than 20 years (1983-2004) should be assessed. At a cutoff date (January 1st, 1997), a change from a primarily surgically based to a consequent multi-modality treatment regimen was implemented. The periods of time before and after that change should be compared. METHODS AND PATIENTS: The data of the DOSAK registry entries on 1038 patients suffering from primary untreated oral and oropharyngeal carcinomas were updated with respect to follow-up and mortality data to achieve a 100% quality of follow-up. The end point (death) was reached in 67% of the overall population. Statistical analysis was carried out by the Trium Analysis Online corporation, Munich. RESULTS: The portion of female and older tumor patients increased, more than half of all tumor patients were clearly in stage IV of the disease at first referral. The portion of patients operated on persisted approximately (80%), the portion of additional treatment modalities could be increased considerably. The fact of a bony infiltration by the tumor and the operability remained highly significantly relevant for survival in multivariate analysis, despite of multi-modality treatment. The survival rate of the patients remained significantly dependent on the clinical stage of the disease in multivariate analysis but could be improved by 10% in the clinical stages II and III and in the patients who could not be operated on. All in all, the cutoff date was statistically relevant for survival in multivariate analysis, i.[Symbol: see text]e. the change in the treatment regimen had a verifiable positive effect on the survival of a unicentric overall population. CONCLUSION: Survival improvement in an overall population via change in treatment strategy is possible in relatively short time; the clinical stages II and III and the non-operable patients have the greatest benefit from a multi-modality treatment.     

青海地区1204例口腔颌面部肿瘤,囊肿,瘤样病变分析

本文对青海地区1204例口腔颌面部肿瘤、囊肿、瘤样病变的病变部位、性质、年龄及性别进行分析。结果为良性肿瘤634例（52．66％），以血管瘤和涎腺混合瘤最多见。恶性肿瘤232例（1．27％），以鳞状细胞癌居第一位，平均患病年龄48岁，随年龄增长，逐年递增。囊肿306例（25．41％），多发生在去下腺。瘤样病变32例（2．66％），多为牙龈瘤。本组良性肿瘤女性高于男性，血管瘤居第一位。良恶性肿瘤之比为2．73∶1，与国内有关报道略有不同。     

低氧对口腔鳞癌细胞系血管内皮生长因子和MMP-2的影响

目的 :研究低氧对体外培养的口腔鳞癌细胞系血管内皮生长因子 (vascularendothelialgrowthfactor ,VEGF)和明胶酶 A(matrixmetalloproteinase 2 ,MMP 2 )的影响。 方法 :分别用酶联免疫吸附实验 (ELISA)和半定量逆转录聚合酶链反应 (RT PCR)测定了低氧处理不同时间段时口腔鳞癌细胞系TSCCa和GNM细胞的细胞中VEGF和MMP 2的活性和mRNA表达情况。结果 :低氧处理 4h时 ,VEGF和MMP 2的活性便显著增加 ,8h时达到最高 ,GNM细胞中VEGF和MMP 2分别增加 2倍和 2 .5倍 ;而TSCCa细胞中VEGF和MMP 2增加的更为明显 ,分别增加了 6倍和 4倍。RT PCR结果显示GNM细胞VEGF和MMP 2mRNA表达水平均较TSCCa细胞高 (P <0 .0 5 ) ,低氧处理时在TSCCa细胞中VEGF和MMP 2增加的尤为明显。结论 :低氧可通过调节口腔鳞癌细胞VEGF和MMP 2的活性和mRNA的表达在口腔鳞癌血管形成中起重要作用
