Tianjin Medical Journal 2016;44(5):629-631
Objective To study the clinical effects of recombinant human epidermal growth factor (rhEGF) gel combined with tacrolimus treatment on facial hormone-dependent dermatitis, and to investigate its influence in skin function and recurrence of dermatitis. Methods Forty-eight outpatients with facial hormone-dependent dermatitis were randomly divided into treatment group (n=24, treatment with tacrolimus combined rhEGF gel) and control group (n=24, treatment with tacrolimus). The moisture of skin, sebum content and transepidermal water loss (TEWL) were examined before treatment and 4 weeks after treatment in two groups. Eczema area and severity index (EASI) were calculated at 1 week, 2 weeks and 4 weeks after treatment. The adverse reactions and recurrence of dermatitis were observed during the treatment as well. Results Compared with pre-treatment, the moisture of skin and sebum content were increased (P<0.05) and the TEWL was decreased (P<0.05) after 4-week treatment. The differences were not statistically significant between two groups. The obvious effective rate of the treatment group (45.8%) was not significantly different from that of the control group (20.8%) after 1 week of treatment (P>0.05), but it is much higher in treatment group after two-week treatment (79.2%vs. 50.0%, P<0.05) and after four-week treatment (91.2% vs. 62.5%, P<0.05). Furthermore, there was no adverse reaction in the treatment group, and the recurrence rate was much lower in treatment group (12.5%) than that of the control group (37.5%,χ2=4.03,P<0.05). Conclusion Recombinant human epidermal growth factor gel has an auxiliary curative effect on facial hormone-dependent dermatitis and can significantly improve skin function, and the recurrence rate of dermatitis is low.
3.Research progress of immunopharmacological experiments of anti-allergic effects of Traditional Chinese Medicine
International Journal of Traditional Chinese Medicine 2021;43(3):308-312
Traditional Chinese Medicine (TCM) treating allergic diseasesis effective and with few adverse reactions. The effects of TCM compound, TCM extracts and Chinese herbal monomers played the anti-allergic role in multiple stages. Such as reducing and preventing target cell degranulation, releasing biologically active mediators, and inhibiting the conduction of signal pathways. Recent studies have found that in addition to anti-allergic effects by regulating cellular and humoral immunity, TCM can also enhance the body’s non-specific immune function to different degrees and help eradicate certain intractable allergic diseases. The development of new therapeutic agents for allergic diseases with good effect and less adverse reactions from Chinese herbal medicine will become a trend in the future research and have broad medical prospects.
