[ABSTRACT] Objective To evaluate the clinical effect of tranexamic acid and glutathione in the treatment of chloasma.

Methods From August 2018 to August 2019, 117 patients with mla-graded chloasma were selected and randomly divided into the microneedle group (group A), intradermal group (group B) and combined group (group C), 39cases each. Glutathione injection and tranexamic acid injection were administered by microneedle in group A, intradermal injection in group B and combined administration in group C, respectively. 

Results The treatment effect of each observation point of patients in group C was significantly better than that of group A and group B (P < 0.05), and there was no significant difference in the incidence of adverse reactions in each group.

Conclusion

Glutathione and tranexamic acid injection can effectively treat chloasma.

[摘要]目的：研究经纳米微针导入0.5%氨甲环酸溶液对中国女性面部皮肤暗沉的疗效及安全性。方法：募集60名无基础病的健康临床受试者，随机分为两组，每组30名。生理盐水组：受试者全面部使用纳米微针导入生理盐水；0.5%氨甲环酸溶液组：受试者全面部使用纳米微针导入0.5%氨甲环酸溶液。两组受试者均每周接受1次治疗，共治疗2个月，每周两组受试者接受治疗前及治疗后72h都检测经皮水分丢失（trans-epidermal water loss，TEWL）、角质层含水量、红斑量、黑素及皮肤弹性，拍摄每组受试者治疗前后面部照片。通过皮肤状态问卷调查受试者满意度及不良反应，治疗结束后1个月、2个月复测TEWL、角质层含水量、红斑量、黑素及皮肤弹性。结果：生理盐水组治疗后72h经皮水分丢失、角质层含水量、红斑量、皮肤弹性与0.5%氨甲环酸溶液组无显著性差异；生理盐水组治疗后黑素数值显著高于0.5%氨甲环酸溶液组；生理盐水组受试者面部照片治疗前后无显著性差异，0.5%氨甲环酸溶液组治疗后面部照片明显比治疗前肤色白皙；生理盐水组受试者及医生满意度显著低于0.5%氨甲环酸溶液组；生理盐水组及0.5%氨甲环酸溶液组皆无不良反应；0.5%氨甲环酸溶液组治疗后1个月的黑素值与初次治疗前的黑素值有显著性差异（P＜0.05）,治疗后2个月的黑素值与初次治疗前测得的黑素值无统计学差异。

结论：纳米微针导入0.5%氨甲环酸溶液可明显改善中国女性面部皮肤暗沉。

Abstract: Objective To observe the clinical effect of delivering 0.5% tranexamic acid solution into skin with microneedles

for facial skin dull of Chinese women.

Methods A total of 60 healthy subjects were enrolled for this study and were respectively divided into 2 groups. 60 cases volunteers were treated by deliverying solution into skin through micropores which the microneedles made. In the first group, volunteers were treated by deliverying physiological saline solution into skin . In the second group, volunteers were treated by deliverying 0.5% tranexamic acid solution into skin . One session every 7 days, all 60 volunteers were treated 8 times. We asses its effect by questionaires for subjective evaluation and side effect, and objective evaluation with digital skin analyzers to record raw pictures and data before and after treatment. Retesting TEWL, skin hydration, erythema dose, melanin value and skin elasticity at the ending of 1, 2 months after all treatment.

Results There was no significant difference in TEWL, skin hydration , erythema dose, melanin and skin elasticity between the saline group and the 0.5% tranexamic acid solution group. Melanin of 0.5% tranexamic acid solution group was relatively lower than the saline group. There was no significant difference in facial photo before and after treatment in the saline group, skin colour was obviously pale compared to that before treatment in the 0.5% tranexamic acid solution group. The subjects and doctors’ satisfaction of the saline group was relatively lower than that of the 0.5% tranexamic acid solution group . There was no adverse reaction report both in the saline group and the 0.5% tranexamic acid solution group. In the 0.5% tranexamic acid solution group , there were significant differences in melanin value before and 1 month after the treatment , while there were no statistical differences before and 2 month after the treatment .

Conclusion Delivering 0.5% tranexamic acid solution into skin with microneedles can significantly improve the facial skin dull of Chinese women .

Abstract: Poly-D,L-lactic acid (PDLLA) filler corrects soft tissue volume loss by increasing collagen synthesis in the dermis; however, the mechanism is not fully understood. Adipose-derived stem cells (ASCs) are known to attenuate the decrease in fibroblast collagen synthesis that occurs during aging, and nuclear factor (erythroid-derived 2)-like-2 factor (NRF2) increases ASCs survival by inducing M2 macrophage polarization and IL-10 expression. We evaluated the ability of PDLLA to induce collagen synthesis in fibroblasts by modulating macrophages and ASCs in a H2O2 -induced cellular senescence model and aged animal skin. PDLLA increased M2 polarization and NRF2 and IL-10 expression in senescence-induced macrophages. Conditioned media from senescent macrophages treated with PDLLA (PDLLA-CMMΦ) reduced senescence and increased proliferation and expression of transforming growth factor-β (TGF-β) and fibroblast growth factor (FGF) 2 in senescence-induced ASCs. Conditioned media from senescent ASCs treated with PDLLA-CMMΦ (PDLLA-CMASCs) increased the expression of collagen 1a1 and collagen 3a1 and reduced the expression of NF-κB and MMP2/3/9 in senescence-induced fibroblasts. Injection of PDLLA in aged animal skin resulted in increased expression of NRF2, IL-10, collagen 1a1, and collagen 3a1 and increased ASCs proliferation in aged animal skin. These results suggest that PDLLA increases collagen synthesis by modulating macrophages to increase NRF2 expression, which stimulates ASCs proliferation and secretion of TGF-β and FGF2. This leads to increased collagen synthesis, which can attenuate aging-induced soft tissue volume loss.
