Objective To investigate and compare the effectiveness of perichondrial cutaneous graft (PCCG) of dorsal auricle for repairing defect after excision of melanocytic nevus in different parts of the face. Methods Between February 2008 and October 2012, 29 cases of facial melanocytic nevus were admitted. There were 11 males and 18 females, aged 3-25 years (median, 11 years). The locations were the upper eyelid in 5 cases, the nose in 15 cases, and the buccal region in 9 cases. The size of the nevi ranged from 1.2 cm × 1.0 cm to 4.0 cm × 2.2 cm. Defects after excision of nevi were repaired by PCCG of the dorsal auricle, which size ranged from 1.5 cm × 1.5 cm to 4.2 cm × 2.5 cm. The postoperative effectiveness was scored by patients according to color match, scar formation, and flatness of the reception site. The satisfaction evaluations were compared by the score among different parts. Results All the PCCG survived. All the patients were followed up 7-15 months (mean, 10 months). All the reception site had good color match and acceptable scar formation. The nasal part had good flatness, and the upper eyelid had poor flatness. Score comparison showed no significant difference in color match between 3 parts (P gt; 0.05). Nasal part had significantly less scar formation than buccal region and upper eyelid (P lt; 0.05), but no significant difference between buccal region and upper eyelid (P gt; 0.05). Nasal part and buccal region both had significantly better flatness than upper eyelid (P lt; 0.05), but no significant difference between nasal part and buccal region (P gt; 0.05). The overall evaluation score of nasal part and buccal region was significantly higher than that of the upper eyelid group (P lt; 0.05), and the score of the nasal part was significantly higher than that of the buccal region (P lt; 0.05). Conclusion PCCG of dorsal auricle has a good color match in repair of facial defect, especially in repair of nasal defect with good flatness and no obvious scar formation.
Objective To detect the expression of heat shock protein 47 mRNA in pathological scar tissue by using real-time fluorescent quantitative reversetranscription-polymerase chain reaction (RT-PCR). Methods The tissues of normal skin(n=6), hypertrophic scar(n=6) and keloid(n=6) were adopted, which were diagnosised by Pathology Department. Based on fluorescent TaqMan methodology, the real-time fluorescent quantitative RT-PCR were adopted to detect the expression ofheat shock protein 47 mRNA. Results Compared with normal skin tissue(0.019±0.021)×105, the expressions of heat shock protein47 cDNA of hypertrophic scar tissue(1.233±1.039)×105 and keloid tissue(1.222±0.707)×105 were higher, being significant differences(Plt;0.05). Conclusion A fluorescent quantitative method was successfully applied to detecting the expression of heat shock protein 47 mRNA. Heat shock protein 47 may play an important role in promoting the formation of pathological scar tissue.
Compound Huangbai liquid coating agent is a preparation that combines multiple traditional Chinese medicinal herbs and has shown significant efficacy in burn treatment. In recent years, the application of this coating agent in burn treatment has received widespread attention, and it plays a role in promoting wound healing, preventing infection, and reducing patient pain. This article reviews the research progress of compound Huangbai liquid coating agent in burn treatment, explores its mechanism of promoting wound healing, evaluates its current advantages and limitations in burn treatment, and provides scientific basis and theoretical support for its better use in burn treatment.
Poland syndrome is a congenital anomaly characterized by unilateral underdeveloped or absent chest wall, accompanied by varying degrees of ipsilateral limb defects. In clinical practice, Poland syndrome is prone to misdiagnosis and missed diagnosis, which delays treatment timing and affects treatment effectiveness, as the current etiology is not yet clear and there is no unified and standardized clinical classification and treatment plan. This article summarizes and elaborates on the etiology, clinical manifestations, classification, diagnosis, and treatment of Poland syndrome by reviewing relevant literature on the diagnosis and treatment of Poland syndrome both domestically and internationally in recent years, in order to enhance understanding of Poland syndrome, provide reference for standardized clinical diagnosis and treatment, and improve the efficiency of diagnosis and treatment.
