Clinical application of autologous fat grafting in hand rejuvenation / 中华医学美学美容杂志

Objective:To investigate the effect of autologous fat grafting in hand rejuvenation and to provide effective clinical treatment for the aging hand.Methods:A total of 52 patients received autologous fat grafting in hand. Fat was collected by liposuction from the abdomen or thigh regions utilizing the superwet technique. The harvested fat was washed and injected to the dorsal hand. Standardized photographs were taken before and after the operation, and the patients＇ satisfaction was evaluated.Results:Picture scores between preoperative and postoperative had statistically significant differences ( P<0.01). The majority of patients (75%) were satisfied with their results. All patients were followed up for 6 months with no infection, fat liquefaction, cysts and other complications occurred. Conclusions:This study provides the clinical basis for fat grafting in hand rejuvenation with high satisfactory rates.

Relationship between disease activity and Th17/regulatory T cells level in peripheral blood of patients with synovitis acne pustulosis hyperostosis osteitis syndrome / 中华风湿病学杂志

Objective To investigate whether the proportions of Th17/Treg balance were impaired in the peripheral blood of patients in different phases of synovitis acne pustulosis hyperostosis osteitis (SAPHO) syndrome.Methods We studied 22 cases diagnosed as SAPHO syndrome and 11 healthy controls.According to the scores of VAS pain,BASDAI and BASFA,the 22 patients were divided into active group and stable group.By means of flow-cytometry,the frequencies of total and different subsets of Th17 and Treg cells in peripheral blood mononuclear cell of different groups of SAPHO syndrome and healthy controls were studied.The values of Th17/Treg balance were analyzed.The relationship was analyzed with Kruskal-Wallis test,Mann-Whitney test and Pearman's test.Results The mean percentage of Th17 cells was markedly higher in the active group [(2.74±0.25)％] than in the stable group [(1.16±0.09)％] (U=0.000,P＜0.01) and healthy controls [(1.13±0.11)％] (U=0.000,P＜0.01).No differences were found among active group [(2.10±0.20)％],stable group [(2.51±0.20)％] and control group [(2.44±0.22)％] (x2=2.16,P=0.339 4).The ratio of Th17 cells to Treg cells was markedly higher in active group [(1.48±0.25)％] than in the other two groups [(0.47±0.03)％] (U=0.000,P＜0.01).We also found the positive correlation of the ratios of Th17/Treg cells with the values of VAS in SAPHO syndrome patients (r=0.752 7,P＜0.01).Conclusion The results demonstrate that the development of SAPHO syndrome is closely related to the imbalance of systemic Th17/Treg cells,Increased ratio of Th17/Treg cells may be the main factor that cause disease recurrence,and then,lead to the manifestations of high levels of inflammation and joint pain.

Vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermal matrix / 中华整形外科杂志

<p><b>OBJECTIVE</b>To introduce and evaluate the technical feasibility and anatomical and functional outcomes of one-stage vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis.</p><p><b>METHODS</b>We retrospectively reviewed our experiences with 17 patients with Mayer- Rokitansky-Kuster-Hauser syndrome treated with primary surgery from September 2010 to April 2013. All patients underwent vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis. We describe the details of this technique, observe the time of epithelization and evaluate the long- term anatomical, functional, and sexual outcomes.</p><p><b>RESULTS</b>The time of epithelization was 13 d (range: 12-15 d). At a mean follow-up of 15 months (range: 12-24 months), the mean postoperative dependence on the vaginal stent was 11.7 ± 1.64 months (range: 9-15 months), the mean depth of the neovagina was (9.0 ± 0.94) cm (range: 7-11 cm), the mean circumference was (12.3 ± 1.36) cm (range: 10.0-14.5 cm) and the mean volume was (105 ± 10) ml (range 85-120 ml). The mean female sexual function index score of the 12 sexually active patients was 29.5 ± 2.6. No spouse reported discomfort during intercourse.</p><p><b>CONCLUSIONS</b>Vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis is an effective and feasible approach for patients with Mayer-Rokitansky-Kuster-Hauser syndrome. The procedure has satisfactory long-term anatomical and functional results. The use of the acellular allogenic dermis is limited by the high price and the potential infection.</p>
