Objective:To determine the clinical efficacy and safety of a fractional CO 2 laser and a 1 064 nm, Q-switched Nd∶YAG laser therapy in the treatment of xanthelasma palpebrarum. Methods:From October 2020 to October 2021, 30 patients (5 males and 25 females) with bilateralxanthelasma palpebrarum of the eyelid were enrolled in the Department of Dermatology, the First Affiliated Hospital of Xiamen University. The age ranged from 38 to 67 (51±7) years. One side was randomly treated with fractional CO 2 laser as the fractional group, and the other side was treated with Q-switch 1 064 nm Nd∶YAG laser as the Q-switch group. The treatment was given every 28 days for 4 times. Before treatment and 1 month after the last treatment, the general pictures were taken to compare the clinical effect. Skin ultrasound was used to measure the difference of tumor thickness before and after treatment. The incidence of adverse reactions, such as local scar, hyperpigmentation or hypopigmentation after inflammation, were recorded. Results:Under general photos, there was statistically significant difference in efficacy scores between the two groups before and after treatment ( Z=-3.082, P<0.05). By comparison of tumor thickness under skin ultrasound, the difference between the two groups before and after treatment was statistically significant ( t=21.60, P<0.05; t=17.29, P<0.05); there was no statistically significant difference between the two groups before treatment ( t=0.46, P=0.650), but there was statistically significant difference between the two groups after treatment ( t=8.41, P<0.001). No serious adverse reactions occurred in both groups. Conclusions:Fractional CO 2 laser or Q-switch 1 064 nm Nd∶YAG laser can safely and effectively improve xanthelasma palpebrarum, in which the effect of fractional CO 2 laser is much better.

Referring to ZHANG Xichun's experience in treating dysentery from cold-fire accumulation, the treatment of ulcerative colitis (UC) in this paper can be divided into three stages including cold-fire accumulation stage, excessive heat and putrid intestine stage, and healthy qi deficiency and pathogen lingering stage. For people with slippery and excess pulse in the cold-fire accumulation stage, Xiaochengqi Decoction (小承气汤) added with Baishao (Radix Paeoniae Alba) and Gancao (Radix et Rhizoma Glycyrrhizae) can be used for purgation, while those with deficient pulse, Huazhi Decoction (化滞汤) or Xieli Decoction (燮理汤) can be used. In the excessive heat and putrid intestine stage, Tongbian Baitouweng Decoction (通变白头翁汤) and Jiedu Shenghua Elixir (解毒生化丹) are suggested. In the healthy qi deficiency and pathogen lingering stage, it is advised to use Jiedu Shenghua Elixir added with Shanyao (Rhizoma Dioscoreae), and Sanbao Porridge (三宝粥). Additionally, the medication rules, dosage and administration characteristics of Huanglian (Rhizoma Coptidis)-Rougui (Cortex Cinnamomi), Yadanzi (Fructus Bruceae), Diyu (Radix Sanguisorbae), Shanyao and Liuhuang (Sulphur) by ZHANG Xichun have been summarized with the help of modern pharmacological research, so as to provide new ideas for the treatment of UC by TCM.
