Objective To evaluate the preliminary outcome of stable vitiligo treatment with ReCell(R )technique.Methods Six patients with stable vitiligo were treated with ReCell(R ) technique.In each patient,a thin razor-thickness cutaneous biopsy was harvested from uninvolved area near the vitiligo patches.It was then processed through the ReCell(R ) system and 1 ml autologous epidermal cell suspension was obtained.The lesion area was dermabraded using a diamond fraise wheel to the dermoepidermal junction.The cell suspension was then sprayed on the wound and covered with non-adhering dressings.Results The patients were followed up for 6 months.5 patients presented with repigmentaion in the treated area.There was no significant response in one patient who was diagnosed as systematic vitiligo.Conclusions The ReCell(R ) technique is an alternative treatment for stable vitiligo patients.The clinical outcome will be satisfactory when appropriate patients are selected.

Medical quality and safety are essential safeguards for the harmonious society in China, directly affecting people's sense of security and happiness. Continuously improving medical quality and ensuring medical safety are fundamental and essential to implementing the strategies of the Party Central Committee and the State Council, and promoting the construction of a healthy China. In recent years, with the rapid development of China's economy and the people's increasing emphasis on their own health and safety, China's plastic surgery industry has achieved significant progress and yielded outstanding results. However, along with the rapid growth of the industry, medical quality issues and safety accidents have occurred frequently, attracting widespread attention from all sectors of society. This article briefly outlines the history of quality management and quality control for medical quality and safety in China's plastic surgery specialty. It explores the development of quality management from its origin to medical quality management, as well as the responsibilities and contributions of the National Plastic Surgery Quality Control Center in improving industry standards and ensuring patient safety. It aims to provide support for the standardized management of the plastic surgery industry in the future, so as to promote its healthy and sustainable development.

Objective: To study the morphological characteristics and important anatomical structures of each soft tissue layer of gluteal region, and discuss the recommended levels and safe areas for liposculpture in this region. Methods: Twenty-eight specimens of unilateral buttocks from 14 adult cadavers, including 16 specimens of unilateral buttocks from 8 fresh cadavers and 12 specimens from 6 formaldehyde fixed cadavers were dissected. Among the cadavers, there were 2 males with an average age of 49 years, and 12 females from 23 to 72 years old, median age 46 years. Through anatomy study of soft tissue layers of gluteal region, the morphological features of each layer were observed and documented, and the characteristics of fascia system and adipose tissue, as well as the relationship between the blood vessels and nerves with corresponding layers. Results: The layers of the gluteal region that range from superficial to deep are skin, subcutaneous fat, superficial fascia system, deep fascia system, muscle and fascia compartments. Subcutaneous fat is distributed in superficial and deep layers; the superficial fascia system is well developed and dense with a layered structure; the deep fascia is thin with the characteristic of epimysium. There is a danger zone for deep fat graft in the gluteal region, with its apex at the first sacral vertebra, and its base goes along the gluteal fold, compromising the thighs′ medial two-thirds. Nearly all important blood vessels and nerves of gluteal region are located in deep layer of this danger zone. Conclusions Based on the characteristics of buttocks of Chinese people, liposuction is mainly performed in the iliolumbar region and posterolateral thigh, which can significantly increase the relative height and fullness of buttocks. For full buttocks, deep fat can be sucked appropriately, which should be longitudinal and gentle to reduce the damage to the superficial fascial system. There is a high risk for fat graft in the buttock. It is recommended to use a blunt needle with an inner diameter of more than 3 mm parallel to the fiber orientation of gluteus maximus for uniform fan-shaped injection with needle withdrawal. Satisfactory result can be obtained by injecting most fat into the subcutaneous adipose layer. Deep injection of grafts into dangerzoneis forbidden.

BACKGROUND: Due to adipose-derived stem cells (ASCs) being easy to obtain, their rapid proliferation rate, and their multidirectional differentiation capabilities, they have been widely used in the field of regenerative medicine. With the progress of decellularized adipose tissue (DAT) and adipose tissue engineering research, the role of DAT in promoting angiogenesis has gradually been emphasized. METHODS: We examined the biological characteristics and biosafety of DAT and evaluated the stem cell maintenance ability and promotion of growth factor secretion through conducting in vitro and in vivo studies. RESULTS: The tested ASCs showed high rat:es of proliferation and adhered well to DAT. The expression levels of essential genes for cell stem maintenance, including OCT4, SOX2, and Nanog were low at 2–24 h and much higher at 48 and 96 h. The Adipogenic expression level of markers for ASCs proliferation including PPARγ, C/EPBα, and LPL increased from 2 to 96 h. Co-culture of ASCs and DAT increased the secretion of local growth factors, such as VEGF, PDGF-bb, bFGF, HGF, EGF, and FDGF-bb, and secretion gradually increased from 0 to 48 h. A model of full-thickness skin defects on the back of nude mice was established, and the co-culture of ASCs and DAT showed the best in vivo treatment effect. CONCLUSION The application of DAT promotes wound healing, and DAT combined with ASCs may be a promising material in adipose tissue engineering and regenerative medicine.

In 2022, general president Xi Jinping pointed out that "high-quality development is the top task of building China into a modern socialist country in all respects" at the 20th National Congress of the Communist Party of China. Since then, various industries have embraced the trend of high-quality development. This article aims to provide a specific reference point for the high-quality development of the plastic and aesthetic industry, based on the understanding of national policy documents and combined with the current situation and characteristics of the plastic and aesthetic specialty.

Objective:The purpose of this study was to observe the anatomical features in the area of forehead and further to discuss precautions of forehead autologous fat injection.Methods:A total of 12 fresh adult cadaveric specimens (6 males and 6 females, 47.5±11.7 years old) were studied during January 2018 to December 2018. Combined with routine anatomy and microanatomy, forehead tissues were dissected to observe important structures and their surroundings. The important blood vessels and tissues thickness were measured by electronic vernier caliper.Results:The forehead is composed of skin, subcutaneous adipose tissue, superficial musculoaponeurotic system(SMAS), loose connective tissue and periosteum. There are three superficial fat compartments. The width and length of superficial central forehead compartments is(2.17±0.27) cm and(4.16±0.38) cm. The width and length of left superficial lateral forehead compartments is(2.09±0.31) cm and(3.65±0.39) cm and right superficial lateral forehead compartments is(2.14±0.29) cm and(3.18±0.55) cm. The three deep fat compartments shape is similar to superficial fat compartments. It is an avascular layer.Retro-orbicularis oculi fat lies deep to the supraorbital area with the thickness is (2.58±0.03) mm and the length is (2.55±0.05) mm. The blood supply of forehead is provided by the supratrochlear artery, the superaorbital artery and the superficial temporal artery with internal diameters of (1.01±0.16) mm, (0.85±0.12) mm and (1.35±0.15) mm, respectively.Conclusions:Forehead autologous fat transfer should be injected into the avascular forehead deep fat compartments. Avoiding injected into superficial fat compartments to avoid unnatural mask face. Because there are potential channels in the superficial central fat compartments and the area of the upper eyelid, it should be avoided to form periorbital migratory fat granuloma caused by postoperative acupressure.
