Effect of the surgical treatment on the keloid of mons pubis with postoperative radiotherapy / 中华医学美学美容杂志

Objective To explore an effective surgical treatment to the keloid of mons pubis.Methods From March 2008 to January 2015,local flap and adjacent flap (including ilioinguinal flap and rectus abdominal musculocutaneous flap) were performed,and used to repair the defect after surgical removal of the keloid in 25 patients,and all the patients were received postoperative local radiotherapy,and then chi square test was applied to evaluate the effect in the six aspects,including perineal form,skin color,pubic hair distribution,satisfactory effect,skin texture and sense.Results The local flap group was better than the adjacent flap group in perineal form,skin color,pubic hair distribution,satisfactory effect,but there was no significant difference in skin texture and sense.Conclusions For the keloid of mons pubis,the first choice is local flap graft,which can maintain the normal mons pubis formation as most as possible,while the wound is so large that the local flap cannot work,and therefore the vascular pedicle axial flap should be used.

A novel treatment for facial acne scars: dermabrasion combined with Recell® (skin active cell transplantation) technique / 中华整形外科杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and risksof the treatment of facial acne scar with dermabrasion combined with Recell® technology.</p><p><b>METHODS</b>30 patents with II or III degree facial acne scars were treated with dermabrasion and Recell® (skin active cell transplantation) technique in our department from October 2010 to October 2011. The affected area in the face was dermabraded with micro motor system. Then a small piece of razor-thickness skin graft was obtained and processed with Recell® kit. Several milliliterof autologous uncultured epidermal cell suspension was applied to the facial wound and covered with appropriate dressings.</p><p><b>RESULTS</b>Theeffectiveness and risks of this treatment was evaluated with regard to wound healing time, postoperative complication rate, erythema period, etc. Wound healing time was shortened to 5-7 days. The erythema period was also observed shortened with this technique. Within the follow up period, no hyperpigmentation was reported in this case serial.</p><p><b>CONCLUSION</b>Dermabrasion combined with Recell® (skin active cell transplantation) technology can provide a safety and effective treatment approach for patients with facial acne scars.</p>

Change in blood flow of rats with diabetes mellitus after the acute hind limb ischemia / 基础医学与临床

Objective To establish the acute hind limb ischemia on Wistar rat with diabetes mellitus.MethodsThirty diabetes rats were induced by intraperitoneal STZ (50 mg/kg) injection, as well as the blood glucose level tested over 16.8 mmol/L. The rats were ligated on the left femoral artery, then the blood perfusion on the hind limbs ischemia was measured by LDPI after the operation. Results The fasting plasma glucose level on 22 Wistar rats(81.5%) was kept above 16.8 mmol/L, and the hind limb blood perfusion would recover slowly to the level of the right side from 1 to 14 day (P
