Objective@#To investigate the clinical effect of diced cartilage in correcting nasal alar base depression after cleft lip surgery.@*Methods@#A retrospective study was conducted in 15 patients of nasal deformity after lip surgery from January 2018 to January 2019. All the patients were taken from autologous costal cartilage to reconstruct the outline of nasal malformation, and the remaining autologous costal cartilage was cut into 0.5-1.0 mm pieces and filled into the basilar lacunar space of the nasal alar by the 1 ml syringe whose anterior needle nipples was removed. The effects of visual images before and after operation were compared and analyzed by Adobe Photoshop CS6 software. The patients were followed up for 6-15 months (mean 10months). The satisfaction and complications of the patients were investigated.@*Results@#The nasal alar base was significantly elevated and the outline of the nasal deformity was improved in 15 patients after operation. The overall effect was satisfactory and no obvious complications were found. No obvious absorption was found in the follow-up.@*Conclusions@#The application of diced cartilage to correct the nasal alar base depression after cleft lip surgery was a feasible method with important clinical value. It advanced in taking good use of the remaining cartilage and reducing the damage to both the donor and recipient area.

OBJECTIVE@#To investigate the association between angiopoietin-like 4 (ANGPTL4) and aldolase A (ALDOA) in human melanoma cell. 
@*METHODS@#Overexpression or knockdown of ANGPTL4 was performed in WM-115 or WM-266-4 cells, respectively. The expression of ANGPTL4 and ALDOA was measured by RT-PCR and Western blot, respectively. The promoter activity of ALDOA gene was determined by luciferase assay.
@*RESULTS@#The promoter activity of ALDOA gene and the expression of ALDOA (mRNA and protein) were increased or decreased in the melanoma cells with overexpression or knockdown of ANGPTL4, which was blocked by selective protein kinase C (PKC) inhibitor or restored by PKC agonist, respectively.
@*CONCLUSION@#ANGPTL4 promotes ALDOA expression in human melanoma cell in a PKC dependent manner.

Objective To evaluate the clinical value of multislice-CT angiography (MSCTA)in planning for the patients undergoing deep inferior epigastric artery perforator (DIEAP) flap operations. Methods Eighteen patients were performed with a 16-slice CT scanner to evaluate the deep inferior epigastric artery perforator prior to DIEAP flap operations. Axial, multiplanar reconstruction( MPR), maximum intensity projection(MIP) and volume rendered (VR) images were analysed and the origins, calibers, courses and anatomic relationships of the deep inferior epigastric artery perforator were evaluated. The anastomosis between the superficial inferior epigastric artery and the main perforator was observed as well. The images were classified into three grades based on the vessels'appearance. A + indicated the vessel appeared clear,continuous and thick. A- indicated the vessel appeared foggy,discontinuous and thin or the vessel partly showed. B indicated no related vessel can be seen. Other 18 patients undergoing conventional abdomen-pelvis CT scans for other reasons were used for control group to compare their CT findings of the deep inferior epigastric artery perforator. Results MSCTA well showed the course of the deep inferior epigastric artery (DIEA). Of the 18 cases, 17 cases appeared as A +, another one A -. It precisely displayed the origins, subcutaneous and intramuscular courses, relations of the main perforators on all cases of showing A +. The exact points where the chosen perforator vessels emerged from the rectus abdominis muscle fascia were located precisely. The superficial inferior epigastric arteries were mostly displayed and the connection between the arteries and the largest-caliber perforator from the deep system could also be shown clearly. Strict concordance with operative findings was found in CTA. Conclusion MSCTA can precisely locate the chosen perforator vessels emerging from the rectus abdominis muscle fascia and it may be a feasible, fast, safe and effective method for preoperative evaluation of DIEAP.
