Objective:To investigate the management of granulation tissue during surgery for infected congenital preauricular fistula and to assess the surgical outcomes. Methods:To summarize the surgical methods and the treatment of granulation methods in 140 cases of congenital preauricular fistula during the period of infection treated in our department from January 2018 to September 2022. The study divided patients into an observation group (79 patients) undergoing fistulectomy without granulation treatment, and a control group (61 patients) where fistulectomy and granulation resection were performed concurrently.. After six months of follow-up, the wound healing, recurrence rates, and the aesthetic assessment of granulation healing were evaluated using the Stony Brook Scar Evaluation Scale(SBSES). Results:The two surgical approaches were applied to a total of 140 patients with infected congenital preauricular fistula. There was no statistical difference in wound healing and recurrence rates between the observation group and the control group. However, the observation group exhibited smaller scars. Conclusion:In cases of infected congenital preauricular fistula, surgical removal without excising granulation tissue is feasible, leading to effective healing and lesser scar formation.

Objective:To explore the effect of nasolabial fold flap in the treatment of nasal ala subtotal defect nasal afte ala tumor operation.Methods:The clinical data of 7 nasal ala subtotal defect patients underwent nasal ala basal cell carcinoma operation in the First People′s Hospital of Lianyungang City from February 2018 to September 2020 were retrospectively analyzed.Results:Seven patients with nasal ala subtotal defect were successfully repaired with nasolabial fold flap. The patients were followed up for 19 to 52 months, the flaps survived, the color was good, the contour was not bloated, the nasal ventilation was not affected, and good results were achieved.Conclusions:The nasolabial fold flap repair of the nasal ala subtotal defect after nasal ala tumor operation has the advantages of simple method, rich materials, no need for vascular anastomosis, no need for secondary surgery, accurate effect and so on, which is suitable for clinical promotion in clinical.

Objective To investigate the relationship between the expression of ITGAV and the radiosensitivity of NSCLC cells. Methods The expression of ITGAV in NSCLC and its relationship to the prognosis of patients who received radiotherapy were analyzed using bioinformatics methods. Differences in radiosensitivity between radio-resistant cells and parent cells were verified by clone formation experiment, and the protein expression of ITGAV was detected by Western blot. The transfection efficiency of si-ITGAV was determined by Western blot and qRT-PCR analyses. The best ITGAV interference sequence was selected to transfect A549R and H1299R cells. Clone formation experiment and flow cytometry were used to detect clone formation, apoptosis and cell cycle of A549R and H1299R cells. Results The expression of ITGAV in NSCLC tissues was significantly higher than that in normal tissues (P<0.05), and NSCLC patients with high ITGAV expression had poor prognosis. The clonogenic ability of the si-ITGAV group was significantly lower than that of the negative control group at 4, 6, 8Gy irradiation (all P<0.05). After 6 Gy irradiation, the apoptosis of the si-ITGAV group was increased (PH1299R<0.0001, PA549R=0.0002), the proportion of G2/M phase cells to A549-siITGAV and H1299R-siITGAV cells was higher than that in the negative control group (PH1299R<0.0001, PA549R=0.0007). Conclusion Interfering with ITGAV expression can increase the radiosensitivity of NSCLC.
