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.

Mild Cognitive Impairment(MCI)is a transitional stage during the progress of cognitive Impairment. Through the analysis of the relativity of apolipoprotein E(apoE),apoE genetic polymorphism,phlegm stagnation and blood stasis,hyperlipemia and MCI,we got this conclusion:syndrome of phlegm stagnation and blood stasis is an important underlying pathogenesis of MCI:the syndrome of phlegm stagnation and blood stasis has a close relation to apoFe4 allele,and lipid-metabolism disturbance is a key link to this relation.
