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.

观察艾维岚®在面部支持韧带修复重塑治疗中对面部软组织松弛复位、提升的临床效果。 方法 选择2022年1月-2022年3月我院收治的28例面部松弛患者为研究对象,均接受艾维岚®面部韧带注射治疗,比较治疗前后患者的面部状态、并发症发生情况、治疗满意度。 结果 28例患者治疗后颧颊沟折痕、鼻唇沟折痕、颧脂肪垫下垂评分均低于治疗后,差异有统计学意义(P<0.05);28例患者术后均自述有轻微肿胀、发红等不良反应,术后3天内全部消失;术后6个月仅1例患者出现2 mm大小的结节,在不做任何干预的情况下,术后1个
眶周色素沉着(periorbital hyperpigmentation,POH)俗称黑眼圈,是临床上常见的一种面部美容问题,主要表现为两侧眼周区域圆形或半圆形的深色外观,呈棕色、深棕色或青紫色,边界不清[1]。因其让人产生一种“衰老”“疲惫”的观感,困扰着许多爱美女性。虽然市场上关于眼周美白的美容产品众多,多种光电技术也用于治疗黑眼圈,但治疗效果偏差较大,并没有完全解决临床需求。
在既往研究中,乳酸常被认为是糖酵解代谢废物,尤其被认为是肌肉疲劳的罪魁祸首。然而,越来越多的研究表明,乳酸不只在临床医学上,在运动领域中也承担着重要角色。本文就乳酸的产生、堆积、清除、乳酸阈值和训练方法以及乳酸的其他功能等相关积极作用进行阐述,以期助力临床医生或运动医学从业者深入了解当代乳酸的生理价值。
