Vertical reduction mammoplasty based on Würinger's horizontal septum / 中华医学美学美容杂志

Objective The vertical mammoplasty which improves the breast morphology and reduces the operative scar has become the first selection of breast reduction.However,the nipple-and-areola complex (NAC) had the risk of necrosis in those severe patients.In this report,we performed the vertical reduction mammoplasty based on Wu'ringer's horizontal septum to reduce the NAC necrosis possibility.Methods Typical Lejourmosque-dome design was performed.The inferior part of glandular tissue and the skin were excised.The NAC was elevated to normal position based on Wu'ringer's horizontal septum.The breast morphology was modified with vertical scar left.Results 79 patients were operated.4 patients had unilateral breast reduction.4 breasts had partial wound dehiscence.They were treated conservatively with topical dressing.No complete NAC necrosis occurred.Conclusions The vertical reduction mammoplasty based on Wu'ringer's horizontal septum is a safe and effective procedure.The NAC necrosis risk is reduced.This method deserves to be recommended.

Growth Factor Release from Lyophilized Porcine Platelet-Rich Plasma: Quantitative Analysis and Implications for Clinical Applications.

BACKGROUND: Freeze-dried platelet-rich plasma (FD PRP) is of potential value for clinical applications. However, growth factors released from FD PRP have not been well studied. Our study investigates growth factor release from FD PRP preparations, compared with other PRP samples, to further facilitate such clinical use. METHODS: We used four experimental groups: (1) Fresh porcine PRP (PRP), (2) PRP activated by calcium chloride (CaCl2) (Ca PRP), (3) PRP activated by CaCl2, followed by freeze drying (Ca-FD PRP), and (4) PRP freeze-dried first, then activated by CaCl2 (FD-Ca PRP). All FD PRP samples were kept for up to 4 weeks at room temperature (22 °C) and reconstituted prior to analysis. Transforming growth factor-ß1 (TGF-ß1), platelet-derived growth factor AB (PDGF-AB), and vascular endothelial growth factor (VEGF) were quantitated by ELISA at 15 min and 1 h incubation times. RESULTS: The concentrations of all growth factors in Ca PRP, measured at 1 h, were significantly higher than those in PRP (p < 0.05). PDGF-AB concentrations in FD-Ca PRP were not significantly different than in Ca PRP (p > 0.05). Levels of VEGF in Ca-FD PRP were not significantly different than in Ca PRP (p > 0.05). However, TGF-ß1 concentrations in Ca-FD PRP, measured at 15 min, were higher than those in Ca PRP (p < 0.05). CONCLUSIONS: PRP was activated efficiently by calcium chloride. Freeze-dried PRP remained rich in growth factors after storage for 4 weeks at room temperature, indicating its ease of use and wider possibilities for clinical applications.

Treatment of concealed penis / 中华医学美学美容杂志

Objective To introduce the clinical manifestations and treatment methods of concealed penis, which is relative rare in plastic surgery. Methods Vertical preputiotomy was performed. The hypoplastic tissuely was excised. After that, there was no prepuce redundant, so that no prepuce excision was needed. Results 7 patients were treated. All were satisfied with the results. Conclusion Concealed penis should be distinguished from phimosis. Circumcision should be avoided in concealed penis patient.

Skin-sparing Mastectomy and Immediate TRAM Breast Reconstruction / 复旦学报（医学版）

Purpose　To introduce our experience about the skin-sparing mastectomy and immediate breast reconstruction using transverse rectus abdominis myocutaneous flap(TRAM).　Methods　For early stage breast cancer,we preserved the breast skin,performed the subcutaneous glandular excision and axillary dissection,immediately reconstructed the breast using TRAM flap.　Results　9 patients were treated by skin-sparing mastectomy and immediate TRAM breast reconstruction.The morphology of reconstructed breasts was excellent.　Conclusions　The skin-sparing mastectomy and immediate TRAM breast reconstruction is safe and effective for treating early stage breast cancer.The incision is relative small and more aesthestic.
