Application of the nasolabial fold "smile" incision approach in posterior buccal cancer ablation / 华西口腔医学杂志

OBJECTIVE@#This study investigated the feasibility and clinical result of radical resection of posterior buccal carcinoma by using the facial nasolabial fold "smile" incision approach.@*METHODS@#From August 2016 to March 2017, 23 patients with posterior buccal carcinoma were included in this study and underwent radical surgery. Upon finishing the cervical lymph node dissection, an arc-shaped incision was made at 1 cm lateral to the ipsilateral angulus oris, extending along the nasolabial fold upward to the inferolateral margin of the nasal alar while downward in direct continuity with the neck dissection incision.@*RESULTS@#Satisfactory exposure and easy resection of the primary tumor with negative surgical margin were achieved in all 23 patients. After 12-22 months of follow-up (16.5 months on average), all patients recovered favorably, and no local recurrence or distant metastasis was observed. Mouth opening was restored to normal in all cases. The scars were hidden in the nasolabial fold, thus named "smile" incision.@*CONCLUSIONS@#For posterior buccal cancer patients, the facial "smile" incision approach can satisfy the need of surgical exposure, facilitate operative performance, and preserve the annular integrity of the lips without affecting the radical tumor ablation, thereby maintaining a favorable mouth opening. With these advantages, the "smile" incision approach is considered worthy of being popularized in clinical application.

Expression of myeloid cell triggering receptor-1 in monocytes at early post-burn stage / 中华烧伤杂志

<p><b>OBJECTIVE</b>To investigate the expression of triggering receptor expressed on myeloid cells (TREM-1) in monocytes of burn patients at early post-burn stage, and its significance.</p><p><b>METHODS</b>The monocytes of 8 healthy volunteers (A group), 29 patients with mild and moderate burn (B group), and 9 patients with severe and very serious burns (C group) were isolated from the blood, and the THEM-1 mRNA and protein expression were determined by semi-quantitative RT-PCR and flow cytometry, respectively. The plasma levels of TNF-alpha, IL-1beta were determined by ELISA method.</p><p><b>RESULTS</b>The value of TREM-1 mRNA expression in A, B and C groups were 0.74 +/- 0.13, 1.24 +/- 0.09, and 1.46 +/-0.07, respectively, and the expression rates on cell surface in the 3 groups were (9 +/- 4)%, (51 +/- 6)%, and (71 +/- 7)%, respectively, and there were significant differences among the three groups (P = 0.000). the plasma levels of TNF-alpha and IL-1beta in B and C groups were obviously higher than that in A group (P = 0.000), and they were positively correlated to TREM-1 expression (rs = 0.68, 0.72, P = 0.000).</p><p><b>CONCLUSION</b>Increased expression of TREM-1 in monocytes of burn patients at early post-burn stage is correlated with the release of inflammatory factors, indicating that TREM-1 might contribute to the onset and development of acute inflammatory response after burns.</p>
