Objective To investigate the protein and mRNA expression of NF-κB and zinc finger protein A20 in the keloid and normal skin and to explore its underlying molecular biological mechanism.Methods The protein and mRNA expression of NF-κB p65 and zinc finger protein A20 in keloid and normal skin was detected by immunohistochemistry and real time quantitative reverse transcription-polymerase chain reaction (RT-PCR).Results The protein and mRNA expression of NF-κB p65 in keloid tissues was higher than those in normal skin tissues (P＜0.05).The protein and mRNA expression of zinc finger protein A20 in keloid tissues was lower than those in normal skin tissues (P＜0.05).Conclusions NF-κB signal pathways and zinc finger protein A20 could play a role in keloid pathogenesis.

Objective To investigate therapeutic effect of bromhidrosis by botulinum toxin A injections and situation of bromhidrosis recurrence.Methods Clinical data of bromhidrosis patients were analyzed in our hospital from January 2013 to June 2014.A total of 89 cases were involved in this study and randomized into two groups:observation group (42 cases) were treated by botulinum toxin A,and patients with the control group (47 cases) were treated by small skin excision.The total effective rate,incidence of complications and recurrence rate in both groups were compared.Results After treatment for 3 months,the total effective rate of both group had no statistical difference (P＞ 0.05).After different treatment,the incidence of complications in observation group of patients was 2.38％ (1/42),and that in the control group was 14.89％ (7/47);complication rates of control group patients was significantly higher than that of the observation group,with statistical significance (x2 =4.245,P＜0.05).After 9 months follow-up,31 cases in the observation group of patients showed bromidrosis recurrence,with recurrence rate of 73.81％;2 patients in the control group showed bromidrosis recurrence,with recurrence rate of 4.26％.Log-Rank test showed that recurrence rate in observation group was significantly higher than that of control group (x2 =43.21,P ＜0.05).Conclusions Botulinum toxin A injection is an uninvasive method for the treatment of bromhidrosis with fewer complications and good effect,but the postoperative recurrence rate is higher and it needs injections for many times.

OBJECTIVETo study the possibility of removal melanin granules from autogenic acellular dermal matrix of giant nevus tissue by H2O2 bleaching technique.

METHODSA total of 32 skin specimens (0.5 cm x 0.5 cm) from giant nevus tissue and 1 piece (0.5 cm x 0.5 cm) of normal skin were obtained from the surgical removal. One giant nevus tissue was chosen as control. The others and the normal skin tissue were treated with solution of 0.25% Dispase II for digestion for 24 hours under normal temperature to remove epidermis. Then each piece was immerged into solution of 0.5% Triton X-100 for digestion for 48 hours in normal temperature. One giant nevus tissue and the normal skin tissue were chosen as control. The others were immerged into solution of different concentrations of H2O2, treated under different temperature and lasting for different period. Lastly, all specimens were treated with HE staining, immunohistochemical staining, light microscopy and so on.

RESULTSAfter giant nevus tissues were treated with solution of 0.25% Dispase II and immerged into solution of 0.5% Triton X-100 in normal temperature, nevus cells and all other cellular components of pigmented nevus tissues can be effectively removed, there were the cavities left by removal of cells without any residual cell debris, but still remaining part of pigment. Then each specimen were immerged into solution of different concentrations of H2O2, under different temperature and lasting for different period which can remove residual melanin granules. In solution of 3% H2O2 for 36 h under 37 degrees C, can remove all the melanin particles, the content of collagen type I in the obtained specimen was not changed. Collagen fibers were uniform in thickness, regular in arrangement with no obvious degeneration.

CONCLUSIONSWith solution of 0.25% Dispase II and solution of 0.5% Triton X-100 in normal temperature, all cells in nevus tissue can be removed effectively. Further treatment with 3% H2O2 at 37 degrees C for 36 h can remove all the melanin particles, while collagen type I has no obvious change. The preparation of acellular dermal matrix of the giant nevus may possibly be applied as autologous tissue implant to repair tissue defects.

Objective To study what affect the incidence and recurrence of keloids. Methods A total of 476 cases were treated with surgery plus adjunctive radiation therapy, intraleisional injection of triamcinolone acetonaide acetate, or surgery plus postoperative topical medicine. The family history and other clinical data were analyzed, including patients' age, sex, the duration of keloids, initiating factors, location, size, treatment method, and recurrence of the keloids. Results Keloids occurred in both male and female with the rate of 1. 83 ∶ 1. 00, with a predominance in woman aged from 22 to 45 years old. Trauma and pierce were the most significant initiating factors. The recurrence was affected by patients family history, treatment methods and the location of keloids, and less affected by keloids size, patients' age and sex. Conclusions Both surgery following adjunctive radiation therapy and intraleisional Kenalog injection are useful methods, which are prior to surgery plus postoperative topical medicine. The keloids incidence has a preponderance in some patients with family history. Therefore,genetic research is important to identify the pathogenetic factors in the keloids.
