Objective:To present a new method of vermilion tubercle reconstruction in secondary cleft lip repair.Methods:39 secondary cleft lip repair patients underwent the operation of vermilion tubercle reconstruction with a vermilion flap transferred vertically. The procedures of the reconstruction mainly included three processes, restoring the vermilion tubercle tissue in the cleft area, widening the vermilion with the vermilion flap, and augmenting the volume of the tubercle with the muscle tissue underlying that vermilion flap. The width of the vermilion and the projection of the vermilion tubercle were measured before and after operation, and then two sets of data were analyzed with paired-samples t test. A patient satisfaction survey was performed postoperatively to evaluate the effect of the reconstruction.Results:The reconstructions of vermilion tubercle were successful in all patients and no complications occurred. The most of new vermilion tubercles located in midline and appeared plump. Follow-up had been completed in 28 patients and the average follow-up period was (9.71±5.02) months. The effective vermilion width increase was from (5.32±0.91) mm, (3.98±0.89) mm, (4.30±0.86) mm before operation to (6.35±0.87) mm, (7.75±1.03) mm, (7.48±0.97) mm after operation in the midline of lip, the peak of cleft side and the midline of short arm, respectively. The postoperative width of vermilion in the cleft side was widened significantly. The projection of the tubercle was increased significantly from (0.38±0.46) mm to (0.83±0.51) mm. 96.4% (27) patients achieved satisfied results of vermilion tubercle reconstruction after operation.Conclusions:The vermilion flap transferred vertically has been found to be an effective method of vermilion tubercle reconstruction in the secondary repair of cleft lip.
Objective:To evaluate the morbidity and causes of long-term abnormal sensation of breasts after typy Ⅰ dual-plane breast implant augmentation via endoscopic assisted axillary approach.Methods:A retrospective analysis was conducted on 53 patients who underwent endoscopic assisted transaxillary type Ⅰ dual plane breast implant augmentation by a same surgeon from July 2014 to December 2016. All patients were followed up for more than 18 months. Hyperesthesia, hypoesthesia and numbness of nipple-areola complex and imframammary fold and breast pain were accessed.Results:According to the palpation and consultation of the surgeon, a total of 10 patients presented with post-operative long-term abnormal sensation of breasts, of which 6(11.3% of the total number) patients presented with hypoesthesia of nipple-areola complex, 1 patient (1.9% of the total number)presented with hyperesthesia of nipple-areola complex, and 2 patients (3.8% of the total number)presented with hypoesthesia of inframammary fold region. One patient (1.9% of the total number) had long-term postoperative breast pain. According to the questionnaire designed to assess breast sensation, a total of 33 patients (64.7%) presented with long-term postoperative breast pain, a total of 12 patients (23.5%) presented with post-operative long-term hyperesthesia of nipple-areola complex, another 5 patients (9.8%) presented with transient hyperesthesia of nipple-areola complex.Conclusions:It is clear that the incidence of post-operative long-term abnormal breast sensation following endoscopic assisted transaxillary type Ⅰ dual-plane breast implant augmentation is comparatively low and controllable.And the main reason for this complication is the peripheral nerve innervation of the nipple areolar complex.

Objective To explore the effect of Salvia miltiorrhiza on proliferation and differentiation of 3T3-L1 cells, so as to provide evidence for further research and clinical application of fat transplantation. Methods The differentiating 3T3-L1 cells after adipogenic induction were incubated with different concentration of S.miltiorrhiza (0.6 g/L, 0.3 g/L, 0.15 g/L, 0.075 g/L, 0.04 g/L, 0.02 g/L). After the 3T3-L1 cells differentiated into mature adipocyte, the cell proliferation viability was determined by CCK-8 assay kit. The lipid droplets accumulation of adipocyte were observed by Oil Red O staining and Image Pro Plus 6.0. The adipogenesis was quantified by measuring lipid content using triglyceride GPO-POD assay kit. Results S. miltiorrhiza promoted a dose-and time-dependent increase in 3T3-L1 cell proliferation viability. The earlier the dosing time was, the better the cell proliferation viability would be; The higher the concentration was, the better the cell proliferation viability would be. Within the six S.miltiorrhiza concentrations confine, S.miltiorrhiza also promoted a dose-dependent increase in 3T3-L1 cell differentiation ability, enhanced the lipid droplets accumulation of 3T3-L1 adipocyte. Conclusion S.miltiorrhiza can promote the increase of adipocyte number via the proliferation and differentiation of 3T3-L1 cells.
Objective To explore the significance of accurate measurement of breast volume by 3D scan in selecting breast aug-mentation models. Methods The patients with breast asymmetry underwent breast augmentation. 3D scanning and accurate volume cal-culation were performed before the operation. The prostheses were selected according to measurement results. Results Twenty patients were admitted in this study. There were 13 patients with bilateral breast size difference of 10 ml to 20 ml. They chose the same type of bi-lateral breast implant. Other patients with bilateral breast size difference of 37 ml to 110 ml chose a different type of bilateral breast imp lant. The absolute value of bilateral breast volume difference between pre- and postoperation was (27.4±3.7) ml and (12.7±4.7) ml, respec-tively. The difference was statistically significant (P<0.05). Conclusion Breast volume measurement by digital imaging before surgerycan provide an objective basis for prosthesis selection. It improves the effects of surgery and patients’satisfaction with breast prosthesis implant.

Objective Recently, increasing number of patients, who have received polyacrylamide hydrogel injection for augmentation mammoplasty, are seeking to have this gel removed regardless of whether they're suffering from symptoms or not. Blunt aspiration, which is widely performed but removes only free hydrogel, leaves residual hydrogel in the breast. Here we're going to report and discuss our methods and ideas of the treatment for polyacrylamide hydrogel-injected breasts. Methods During the period of February 2005 to December 2013, 170 women who had undergone injection of polyacrylamide hydrogel for augmentation mammoplasty presented to us for treatment. A peri-areolar incision was made on the lower border of the areola, followed by dissection to the outer surface of the infiltrated fascia of polyacrylamide hydrogel. The fascia was dissected away as completely as possible and the free polyacrylamide hydrogel was removed from the cavity. Results Almost all the patients were satisfied with the surgical results, except for 5 patients who complained about the flat appearance of the breasts. Preoperative symptoms such as breast lumps, pain, uncomfortable upper-extremity movement and breast firmness were relieved and disappeared after removal of the free polyacrylamide hydrogel and infiltrated capsule. Conclusion The removal of the infiltrated capsule and free polyacrylamide hydrogel as much as possible may be successful in removing breast lumps, pain, and uncomfortable upper -extremity movement due to breast firmness. To remove polyacrylamide hydrogel as much as possible, the removal of the infiltrated fascia and capsule together with the free polyacrylamide hydrogel is recommended.
BACKGROUND:Autologous free-fat transplantation is limited by fat absorption and fibrosis due to fat necrosis. In this study, we explored the feasibility of using bone mesenchymal stem cells (BMSCs) transfected by vascular endothelial growth factor (VEGF) 165 gene to improve the survival of transplanted fat tissues in a rat model. METHODS:Bone mesenchymal stem cells with (group A) and without (group B) VEGF165 gene transfection were each mixed with free transplanted fat tissue; then, they were injected subcutaneously at sites on the backs of 36 Sprague-Dawley rats. A control group (group C) was established by using low-glucose Dulbecco modified Eagle medium. The transplants from groups A, B, and C were gathered respectively at 30, 90, and 180 days after transplantation. Transplanted tissue volume and histology were evaluated, and revascularization was quantified by counting the number of capillaries. RESULTS:The survival rate of the A group was significantly higher than that of the B group (P < 0.05), which was significantly higher than that of the C group (P < 0.05). Histologic analysis revealed that both groups A and B had significantly less fat necrosis and fibrosis (P < 0.05). Group A had significantly higher capillary density than the other 2 groups (P < 0.05), and its chloromethyl-1-1'-dioctadecyl-3,3,3', 3'-tetramethylindocarbocyanineperchlorate-labeled BMSCs were also von Willebrand factor positive. CONCLUSIONS:When transfected by the VEGF165 gene, the BMSCs of a rat can better promote the regeneration of capillaries, which can improve the survival rate of transplanted free-fat tissue. This experiment combined correlative theory and techniques of stem cell research, genetic technology, and autologous free-fat transplantation. It may provide a new way to improve the survival of tissue undergoing autologous free-fat transplantation.
