A Modified Suture Technique to Improve Scar Appearance in Wounds Under High Tension.

The purpose of this study was to introduce a modified suture technique and to compare its effects on skin scar formation with 2 traditional suture methods: simple interrupted suture (SIS) and vertical mattress suture (VMS). Three groups of healthy adult female Sprague-Dawley rats were selected (6 replicates in each group), and the full-thickness skin of 5 cm × 0.2 cm was cut off on the back of the rats after anesthesia.

[An experiment study and clinical observation of the influence of free-skin-grafted scrotal avulsion injuries on spermatogenesis].

Objective: To explore the influence of Free-skin-grafted penoscrotal avulsion injuries on spermatogenesis.

Methods: Forty-two male New Zealand albino rabbits during child-bearing period were divided into the experimental group (n = 24) and the control group (n = 18) using random digits table, and 24 female rabbits with reproductive history were used for mating experiment. The experimental group animal's scrotum skin were excised, and the split skin from abdominal region was used to repair the skin defect of scrotum.

[Clinical efficacy of keloids treated by surgical ablation and immediate postoperative adjuvant radiotherapy].

Objective: To evaluate the clinical efficacy of intralesional excision and immediate postoperative adjuvant radiotherapy in the treatment of keloids.

Methods: Eighty-one patients with a combined total of 86 keloids were treated with 6 MeV electron beam radiotherapy after surgical intralesional excision of keloids. All received a total dose of 15 - 20 Gy for 5 consecutive days beginning the day of surgery.

[Anatomical study and clinical applications of the posterior tibial artery intermuscular septum branches island flaps].

Objective: To report an anatomical basis for the posterior tibial artery intermuscular septum branches island flaps and its clinical value.

Methods: The origin,course, number, caliber and distribution of the posterior tibial artery intermuscular septum branches were studied in 10 adult cadavers(20 legs). 10 cases of homonymy and opposite side ankle and adjacent soft tissue defects with posterior tibial artery intermuscular septum branches island flaps, aged 20-50 years.
