Improvement of Atrophic Acne Scar and Skin Complexity by Combination of Aqueous Human Placenta Extract and Mesenchymal Stem Cell Mesotherapy

Atrophic scars, a permanent complication of severe acne, have negative effect on psychology in adolescent. The treatment of atrophic scar is depended on types of scar and it is difficult to improve by a single treatment. Mesenchymal stem cell is a scientific approval for surgery scar treatment and wound healing. We present a case report of female presented with atrophic acne scar distributed on both cheeks. The case aims to prove that the combination of MSCs and aqueous human placenta extract (RGF&#174) contained bioactive therapeutic molecules obviously promoted the improvement of skin scar to reach the optimal outcomes. We first found that MSCs-contained human placenta extract solution combination subcision improves the atrophic acne scar and skin complexity by enhancement of skin cell regeneration.

Effective Treatment of Atrophic and Icepick Acne Scars Using Deep Non-Ablative Radiofrequency and Multisource Fractional RF Skin Resurfacing

Background and Objectives: Effective treatment for atrophic (depressed) and icepick acne scars requires treatment of both epidermis—for roughness, texture and hyperpigmentation, and the dermis—for collagen remodeling. All first generation radiofrequency systems allow nonablative RF treatment while a few others allow simple bipolar Fractional RF skin resurfacing. The FDA cleared multisource radiofrequency therapy system (EndyMed PRO, EndyMed Ltd., Cesarea, Israel) allows, for the first time, phase controlled multisource RF for both deep (up to 11 mm) non ablative RF and fractional RF skin resurfacing on the same treatment device. Study Design/Materials and Methods: Ten subjects with atrophic acne scars were enrolled in the study. Patients were photographed using standardized methods. In each treatment session, each patient received a full face 3DEEP non ablative skin tightening treatment followed by a Fractional skin resurfacing treatment. The treatment sessions were repeated once a month to a total of up to 4 treatments. Results: All subjects experienced mild-moderate edema and erythema as an immediate response to treatment. Edema resolved after up to three hours post treatment and erythema lasted up to 2 days. Micro ablative crusts were formed 1 - 2 days post treatments and lasted up to 5 days on facial areas. Patients' photographs—before each treatment session and 1 and 3 months after the last session—were graded according to the accepted Cosmetic Improvement Scale. All patients obtained significant skin improvement. Seventy percent of patients had 50% - 75% improvement one month after the third treatment session while the other thirty percent experienced a 25% - 50%. Discussion and Conclusions: The presented results describe for the first time a new treatment system (EndyMed PROTM) that allows both deep non ablative RF delivery and Fractional skin resurfacing on the same treatment platform. This work shows the synergy of combining these two applications for the improvement of acne scars, as well as for some secondary possible pigmentation and vascular improvement.

Abdominal and pelvic adhesions: Possible role of leiomyomas and skin scar anomaly in profiling high risk patients

Background and aims: Adhesions can cause important morbidity including abdominal and pelvic pain, intestinal obstructions, and infertility. When adhesions are formed, there is no efficient method, nowadays, to resolve them, thus the reduction of their prevalence relies on the prevention. Profiling high risk patients for abdominal and pelvic adhesions (APA) is an important step to this prevention. The risk factors of adhesions in our institution, the association between APA, leiomyomas and skin scar anomaly (SSA) were investigated. Methods: A cross-sectional study was conducted from March 1st to June 30th 2013 including patients who underwent laparotomy or laparoscopy. Patients’ characteristics, presence of a SSA and leiomyomas, as related to adhesions, were analyzed. Student’s t, Pearson’s Khi-square, Fisher’s Exact, Mann-Whitney tests and logistic regression were used. P values < 0.05 were considered statistically significant. Results: The frequency of adhesions was 41.74%. Patients had a mean age of 32.69 ± 8.94 years. Those with a previous abdominal surgery (PAS), SSA and leiomyomas had respectively 12 times [OR: 11.98, CI95 (4.63 - 30.97)], 3 times [OR: 2.79, CI95 (1.16 - 6.71) and 2.5 times [(OR: 2.49, CI95 (1.07 - 5.78)] more adhesions. In logistic regression, a PAS and leiomyomas remained associated significantly to adhesions with p = 0.000 and p = 0.037 respectively. Conclusion: In peritoneal adhesions, leiomyomas and SSA are other factors that may allow a cautious selection of high risk patients who must benefit from particular attention during surgery. Further well designed studies are necessary to investigate the accurate clinical relation among those three conditions.

Expression of MMP-1 in the Scar Tissue of Skin and Oral Mucosa

[Objectives] To investigate expression of MMP-1 in the scar tissue of skin and oral mucosa,and to explore if there is the significance of MMP-1 in the scar of skin and oral mucosa.[Methods]All samples were collected from surgical postoperative soft tissue from Department of Oral and Maxillofacial Surgery and Plastic Surgery in the Affiliated Qingdao Hiser Medical Center of Qingdao University Medical College,including 22 samples of dermal scar tissue,20 samples of normal skin tissue,and 13 samples of oral mucosal scar tissue,and 20 samples of normal oral mucosal tissue. HE staining was used to observe the morphology and collagen arrangement of fibroblasts in the scar tissue,the expression of MMP-1 in different tissue was observed by immunohistchemical staining. [Results] The positive expression rates of MMP-1 in skin scar tissue,oral mucousal scar tissue,normal skin tissue and normal mucosal tissue were 27. 27%,69. 23%,5. 00%,10. 00%. Comparison of positive expression of MMP-1 in skin scar tissue and oral mucosal scar tissue: the positive expression rate of MMP-1 in oral mucosal scar tissue was higher than that of MMP-1 in skin scar tissue,and the statistically significant difference was found between them( P < 0. 05).Comparison of positive expression of MMP-1 in skin scar tissue and normal skin tissue: the positive expression in skin scar tissue was higher than that in normal skin,and the statistically significant difference was found between them( P < 0. 05). Comparison of positive expression of MMP-1 in oral mucosal scar tissue and normal oral mucosal tissue: the positive expression rate of MMP-1 in oral mucosal scar tissue was higher than that in normal mucosal tissue,and the statistically significant difference was found between them( P < 0. 05). Comparison of positive expression of MMP-1 in normal oral mucosal tissue and normal skin tissue: the positive expression rate of MMP-1 in oral mucosal scar tissue was higher than that in normal mucosal tissue,and there was no statistically significant difference between them( P > 0. 05). [Conclusions] The positive expression of MMP-1 was different from that in the scar tissue of the oral mucosa,indicating that MMP-1 might be related to the severity of scar formation in different tissues.

病理性瘢痕形成的细胞分子机制的研究进展

皮肤损伤在愈合后会形成纤维化组织,即瘢痕。其中的病理性瘢痕因其外观不佳及痛痒不适感,严重影响患者的生活质量。然而,目前病理性瘢痕的发病机制尚不完全明确,缺乏有效的动物模型及临床根治手段。本文回顾总结了病理性瘢痕免疫微环境中的细胞分子学机制与相互作用,旨在为病理性瘢痕诊断标志物与治疗靶点的研发以及组织工程构建的优化提供参考。
