Objective To observe the therapeutic effect of Guizhi Decoction plus Yupingfeng Powder for chronic urticaria and its effect on serum total IgE level.Methods One hundred and twenty patients were randomly divided into treatment group,control group 1 and control group 2,40 cases in each group.The treatment group was treated with Guizhi Decoction,Yupingfeng Powder and Loratadine Tablets orally,the control group 1 was given intramuscular injection of Bacillus Calmette-Guerin polysaccharide nucleic acid and oral use of Loratadine Tablets,and the control group 2 was only given oral use of Loratadine Tablets.The course of treatment covered 5 weeks.The levels of serum total IgE in the three groups were determined before and after treatment,and the therapeutic effect was evaluated after treatment.Results (1) The total effective rate was 85.0％ in the treatment group,80.0％ in the control group 1,and 55.0％ in the control group 2.The effect of control group 1 and the treatment group was superior to that of the control group 2 (P＜ 0.05),but the difference was insignificant between the treatment group and control group 1 (P＞ 0.05).(2)Before treatment,the serum total IgE level of the three groups was higher than that of the normal control group (P ＜ 0.05).After treatment,the serum total IgE level of the three groups was obviously decreased (P ＜ 0.05 compared with that before treatment);the inter-group comparison results showed that the effect of the treatment group and control group 1 on decreasing the serum total IgE level was superior to that of the control group 2(P ＜ 0.05),while the effect of the treatment group was similar to that of the control group 1 (P ＞0.05).(3) During the treatment,blood routine examination indexes and hepato-renal function of the three groups showed no abnormal changes,neither adverse reaction was shown.Conclusion Guizhi Decoction plus Yupingfeng Powder exerts certain therapeutic effect for the treatment of chronic urticaria,and can decrease the serum total IgE level,thus to stabilize the curative effect and reduce the recurrence.

A 13-year-old female patient presented with itchy rashes on the right foot for 5 years. Skin examination revealed scattered flat, reddish-purple, slightly scaling papules on the inner side of the arch of the right foot, scattered light red papules on the outer side of the right great toe, and scattered domed reddish-purple papules on the right heel with collar-shaped keratinization around the base. Histopathological examination of the papule on the right heel revealed epidermal hyperkeratosis, marked hyperkeratosis around the papule, thickened granular layer and focal liquefaction degeneration of the basal layer with no obvious hyperplasia of the spinous layer; a large number of lymphocytes and plasma cells without atypia infiltrated the dermis, in which there were many small- and medium-sized dilated thick-walled blood vessels lined with prominent plump endothelial cells. The patient was diagnosed with acral pseudolymphomatous angiokeratoma of children, and treated with long-pulsed 1 064-nm Nd: YAG laser once every month. After 7 sessions of treatment, the rashes regressed and decreased in number.

Objective To observe the clinical curative effect of Q-switch Nd YAG laser on the treatment of facial hormone-dependent dermatitis. Methods Attal of 120 patients were randomly divided into two groups. The control group was orally administered antihistaminic drugs and Vitamin B6. Based on drugs applied to the control group, additional Q-switch NdYAG laser radiation therapy was introduced into the treatment group. Results After the treatment,pru-ritus and total scores of skin lesion in the treatment group were less than the control group. A total effective rate of 86.67 % was achieved in the treatment group, while that was 66.67 % in the control group. The difference between the two groups was statistical significant(P<0.05). Conclusion The treatment of facial hormone-dependent dermatitis with large light-spot and low-energy Q-switch Nd YAG laser 1064 nm radiation therapy is safe and effective. There-fore,it is well worth popularizing and trying.

A 25-year-old female patient presented with itchy rashes on her feet for 10 years. Skin examination showed dark red plaques with clear boundaries, whose surfaces were covered with grey-brown scales, on the dorsum of toes and adjacent dorsum of the feet, the extensor aspect of the right ankle and the left Achilles tendon. Laboratory tests revealed that serum anti-hepatitis C virus (HCV) antibody was negative and HCV-RNA quantity was normal. Histopathological examination showed epidermal hyperkeratosis with parakeratosis, irregularly thickened spinous layer, scattered dyskeratotic cells and necrotic keratinocytes in the middle and upper spinous layer, focal liquefaction degeneration of basal cells, dilatation of small blood vessels in the superficial and middle dermis, and perivascular infiltration of a small number of lymphocytes. The patient was diagnosed with necrolytic acral erythema without hepatitis C. After 2-month treatment, the skin lesions completely regressed, and hyperpigmentation remained.
