增生性瘢痕(hypertrophic scar,HS)主要以真皮层的成纤维细胞异常增殖、胶原纤维过度堆积为主要特征,是临床上常见的病理性瘢痕,局部导致的疼痛、瘙痒等不适,可严重影响患者生活.尽管治疗方法多种多样,如物理疗法、激光和手术等,但这些方法的治疗效果通常欠佳.为了寻求一种简便、治疗效果较好的方式,人们将目光投向了注射治疗,如局部注射脂肪来源干细胞(adipose-derived stem cells,ADSCs)及其外泌体、富血小板血浆(platelet-rich plasma,PRP)等.现就对近年来国内外学者对注射治疗增生性瘢痕的研究进展作一综述.

BACKGROUND:The anatomical parameters of the superficial temporal artery branches were measured by a three-dimensional measurement method to provide anatomical reference for relevant clinical operations. METHODS:Seventy original images were selected who had cranial CTA examination. The patients were aged 30-79 years, with an average of 60.0 years, including 32 females and 38 males. After reconstructing the superficial temporal artery by professional medical 3D reconstruction software, its anatomical parameters were measured. RESULTS:The length of the secondary branches of the frontal branch of the superficial temporal artery were 47.6 ± 23.6 mm and 37.3 ± 21.6 mm in males and females, respectively, with a statistically significant difference. The length of the secondary branches of the parietal branch of the superficial temporal artery were 39.6 ± 20.4 mm and 49.2 ± 20.3 mm in young and middle-aged people and older people respectively, which were statistically different. The remaining measures were not statistically different across gender and age groups. The frontal branch of the superficial temporal artery was divided into three types, and the parietal branch of the superficial temporal artery was divided into two types. CONCLUSIONS:The anatomical parameters of the superficial temporal artery branches can be accurately measured by means of 3D visualization, providing an anatomical reference for relevant clinical operations.
