Abstract: Objective To investigate the efficacy of poly (L-lactic acid) application in the rejuvenation of hands, and to analyze the safety of its application. Methods two subjects with aging problems of the hands were given subcutaneous injections of poly-L-lactic acid for hand filling improvement treatment, a detailed protocol of improving treatment was developed and treated, the status of hand improvement in subjects was followed up after treatment, and standardized hand photographs were taken as a contrast basis. Results after 2 month of young onset hand repair surgery on the two propositi, the veins and prominence of the bones of the hand improved significantly in the two propositi, the darker skin complexion state improved, and the collagen content of the hand improved, with gradual fullness of the fingers in subject 1. Three months after the young onset repair surgery, the skin quality of the hand improved significantly more finely in subject 2, and the darker skin complexion problem had largely disappeared, with the bones remaining intact in the two propositi, The venous prominence problems had largely disappeared, the collagen content of the hands had improved significantly, the finger morphology of patient 1 and the problems of dark finger joints had all improved significantly, and none of the 2 subjects had related complications, and the 2 subjects had high satisfaction with the young treatment of polylactic acid hand. Conclusions the use of poly-L-lactic acid in revision treatment of hand rejuvenation has shown remarkable results and a good safety profile.

大阴唇是女性外阴具有重要生理作用的门户结构,具有保持阴道口湿润、维持阴道自洁、防止外来污染的作用[1]。部分女性存在一定程度的先天大阴唇发育不良,外形萎缩褶皱的情况,影响生活质量。
The WSRS is a valid and reliable instrument for quantitative assessment of facial skin folds, with good inter- and intra-observer consistency. By allowing objective and reproducible grading of data, the WSRS should prove a useful clinical tool for assessi
乳酸是葡萄糖或糖原经过糖酵解无氧代谢过程的最终产物。长期以来,乳酸被广泛认为是导致运动能力下降和运动疲劳的代谢废物。然而,近年研究发现,乳酸在机体中具有重要作用:1)乳酸作为能量底物和糖异生前体,不是导致代谢性酸中毒的原因,反而起到缓冲作用;2)乳酸穿梭作用于靶向部位,发挥细胞间信号传导的信使作用;3)乳酸既是脑的重要能源物质,又可以介导运动改善认知和记忆的过程。
