Abstract:
OBJECTIVE To explore the therapeutic effect of Gouqi Compound Granules combined with laser freckle removal on melasma and their regulatory effects on the oxidative/antioxidant system.
METHODS According to the random number table method, 110 patients with melasma admitted to Lin'an District Traditional Chinese Medicine Hospital in Hangzhou City from June 2021 to September 2023 were randomly divided into control group and experimental group, with 55 cases in each group. The control group received laser freckle removal, while the experimental group received Gouqi Compound Granules and laser freckle removal, with continuous treatment for 3 months. The efficacy, satisfaction, adverse reactions, and improvement of skin lesions before and after treatment between two groups lesion color and area score were compared, as well as sex hormonesestradiol(E2), luteinizing hormone(LH), follicle stimulating hormone(FSH), oxidative stresslipid oxides(LPO), malondialdehyde(MDA), glutathione peroxidase(GSHPx), and superoxide dismutase(SOD).
RESULTS The total effective rate of the experimental group was 90.91%, which was higher than that of the control group(74.55%)(P<0.05). Compared with before treatment, the skin lesion color and area scores in both groups decreased after 3 months of treatment, with the experimental group showing a more significant decrease(P<0.05). Compared with the control group, the experimental group showed a significant decrease in serum E2, LH, and FSH after 3 months of treatment(P<0.05). After 3 months of treatment, the serum MDA and LPO in the experimental group were lower than those in the control group, while SOD and GSH Px were higher than those in the control group(P<0.05). The satisfaction rate of 94.55% in the experimental group was higher than 78.18% in the control group(P<0.05). The incidence of adverse reactions in the experimental group was 5.45%, and there was no statistically significant difference compared to the control group of 9.09%(P>0.05).
CONCLUSION The combination of Gouqi Compound Granules and laser freckle removal therapy has a significant therapeutic effect on melasma. It can effectively regulate the patient's oxidative/antioxidant system, sex hormone levels, improve skin lesions, and is safe and reliable, with high patient satisfaction.
