RESUMO
Objective: To evaluate the effect of venous anastomosis by using microvascular coupler during repair and reconstruction surgery after recection of tumor in oral and maxillofacial area. Methods: 20 patients with oral and maxillofacial tumor were chosen for repair of the defects via free flap. Microvascular coupler was applied to combine venous system,however,traditional methods were used in arterial anastomosis. Results: The average time of venous anastomosis using microvascular coupler was (5. 75 ± 0. 53) min,none of the cases were suffered from thrombosis after surgery. Vascular nerosis resulted from arterial spasm occured in 1 flap,reaching the flap survival rate of 95％(19 /20). Neck bleeding occurred in 1 case after surgery,the reflux of the anastomosed vein went smoothly when the blood clot was cleared,flap healing was unaffected. In another case,the coupler released during the surgery due to thick blood vessel wall as well as hypertension among the anastomotic edge,the vessels were manually sutured. Conclusion: With the appropriate indications, application of microvascular coupler may shorten the operating time,without affecting the effect of vascular anastomosis. The possibility of coupler loosing should be alarmed when bumped into great anastomotic tension or thick wall of the vein.
RESUMO
Objective There are quite a few chemotherapeutic adjuvants for the treatment of advanced oral squamous cell carcinoma, but all have their adverse effects. This study was to evaluate the efficacy and adverse effects of the induction chemotherapy of S?1 plus docetaxel and cisplatin in the treatment of advanced oral squamous cell carcinoma. Methods Totally, 84 patients with advanced oral squamous cell carcinoma were randomly divided into an observation and a control group of equal number, the former trea?ted with S?1 plus docetaxel and cisplatin and the latter with 5?fluorouracil, docetaxel and cisplatinand, both for two cycles ( 1 cycle =21 d) . Then the effects and adverse events were evaluated and compared between the two groups of patients. Results No statistically significant differences were observed in the response rate between the observation and control groups of patients (76.19% vs 73.81%, P>0.05). The incidence rates of adverse events, such as nausea and vomiting (66.67% vs 88.10%, P<0.05) and phlebitis (0 vs 19.05%, P<0.05) , were remarkably lower in the former than in the latter group. Conclusion S?1 plus docetaxel and cisplatin is a reli?able induction chemotherapy with few adverse effects in the treatment of advanced oral squamous cell carcinoma.
RESUMO
<p><b>OBJECTIVE</b>To investigate the expression of full-length spleen tyrosine kinase [SYK (L)] mRNA and protein in human oral squamous cell carcinoma (OSCC) as well as its possible effects on the invasion and metastasis of OSCC.</p><p><b>METHODS</b>The expression of SYK (L) was detected in 27 cases of OSCC tissues and its matched adjacent non-cancerous tissues by real-time quantitative polymerase chain reaction (RT-qPCR), Western blot, and immunohistochemistry. Fourteen cases of normal oral gingival tissues were also analyzed as a normal control.</p><p><b>RESULTS</b>Reduced mRNA and protein expression of SYK (L) in OSCC tissues was observed compared with that in normal oral gingival tissues (P<0.01) and adjacent non-cancerous tissues (P<0.05). SYK(L) expression was significantly associated with lymph-node metastasis (P<0.05).</p><p><b>CONCLUSION</b>SYK(L) is a candidate tumor suppressor for OSCC tissues, and has an inhibitive effect on the initiation, proliferation, and lymph-node metastasis of human OSCC.</p>
