ABSTRACT
Objective: To observe the clinical efficacy of auricular point pricking-bloodletting plus auricular point sticking therapy for acne vulgaris. Methods: A total of 66 patients with acne vulgaris were randomized into an observation group and a control group by the random number table, with 33 cases in each group. The observation group was treated with auricular point pricking-bloodletting plus auricular point sticking therapy, and the control group was treated only with auricular point sticking therapy. The treatments of both groups were performed twice a week, 4 weeks as a course of treatment, for 3 courses in total. The scores of skin lesions and dermatology life quality index (DLQI) scores were recorded before and after treatment to assess the clinical efficacy. Results: During the trial, there were 3 cases of drop-out both in the observation group and the control group. After 3 courses of treatment, the total effective rate of the observation group was 96.7％, while that of the control group was 76.7％. The difference between the two groups was statistically significant (P<0.05). The intra-group comparison showed that the scores of skin lesion and DLQI were both decreased with the increase of treatment times, that was, the scores were lower than those at the previous time point (allP<0.05). After 1, 2, and 3 courses of treatment, the scores of skin lesion and DLQI of both groups were statistically different from those of the same group before treatment (allP<0.05). At every time point during the treatment, the scores of skin lesion and DLQI of the observation group were lower than those of the control group, and the differences between the two groups were statistically significant (all P<0.05). Conclusion: Auricular point pricking-bloodletting plus auricular point sticking has a better curative effect than auricular point sticking therapy alone in the treatment of acne vulgaris, and has a time-effect correlation.
ABSTRACT
The purpose of this paper is to study the effect of kinetin (Kn) on immunity and splenic lymphocyte proliferation in vitro of aging rats induced by D-galactose (D-gal). Fifty SD rats were randomly divided into five groups: control group, aging model group, Kn low dose group, Kn middle dose group and Kn high dose group. The aging model group was proposed by napes subcutaneous injection of D-gal (125 mg/kg) for 45 d, and anti-aging groups were intragastrically administered with 5, 10, 20 mg/kg of Kn respectively from day 11. IgG, IgA, IgM contents of serum, the apoptosis percentage, stimulation index (SI) and proliferation index (PI) of splenic lymphocyte in vitro were evaluated. The results showed that the apoptosis percentage of splenic lymphocyte in aging model rats was higher, the serum IgG, IgA and IgM contents, SI and PI were lower than control group. Kn significantly decreased the apoptosis percentage of splenic lymphocyte, while increased the serum IgG, IgA and IgM contents, SI and PI in aging model group. These results suggest that Kn could inhibit the apoptosis, while promote the proliferation of splenic lymphocyte, and then effectively enhance the immune power of the aging rats and slow down the aging process.
