ABSTRACT
Objective To observe the clinical efficacy of dye laser combined with Xin'an repair solution in the treating superficial infantile hemangioma(IH). Methods 100 patients with superficial IH were randomly divided into observation group and control group.The observation group received dye laser combined with Xin'an re-pair solution,while the control group was treated only with dye laser.The clinical efficacy and the rate of complica-tions after treatment were compared between the two groups,and the different efficacy between the head neck group and the non head neck group in the observation group was further analyzed. Results The total effective rate of the observation group(90%)was significantly higher than the control group(70%),and the difference was sta-tistically significant(P<0.05).The rate of complications in the observation group was significantly lower than that in the control group(6%vs.32%,P<0.05).In the observation group,the total effective rate of head neck group was better than that the non head neck group(P<0.05). Conclusion Dye laser combined with Xin'an repair so-lution is effective in the treatment of superficial IH,and it can significantly reduce complications.It is evidently ef-fective for head and neck superficial IH.
ABSTRACT
Objective There is a significant increase of squamous cell carcinoma antigen ( SCCA) in patients with common skin diseases .The aim of this study was to investigate the difference expression of serum SCCA in patients with common skin diseases . Methods A total of 497 patients with 14 kinds of common skin diseases from the Department of Dermatology were recruited , and the serum SCCA was measured . Results The positive rates of SCCA in 116 patients with psoriasis and 37 patients with erythroderma were 90 .5% and 100%, respectively .The common skin diseases with positive rate of SCCA greater than 60% includes eczema (61.7%), generalized dermatitis (65.1%),pemphigus (61.1%), bullous pemphigoid (62.2%).The SCCA values in pustulosa (1.76 ±1.22 ng/mL) and arthropathica psoriasis (1.69 ±1.05 ng/mL) were decreased compared with pustular (2.86 ±1.46 ng/mL) and arthropathica psoriasis (3.56 ±1.84 ng/mL) (P<0.05). Conclusion The SCCA value may have a relationship with the increase of the performance of keratinization and desquamation in the skin diseases , and it could be used as a valuable indicator for the diagnosis and treatment in patients with cutaneous diseases .
ABSTRACT
Objective To investigate the efficacy of acupoint injection of Astragalus on contents of SOD,HYP and MDA in skin of aging mice in-duced by D-galactose. Methods The mice were randomly divided into normal group,model group,Astragalus group,and saline group(n=15). Except for the normal control group,the mice of other groups were treated with continuous subcutaneous injection of D-galactose to establish mice ag-ing model. The Astragalus group mice was injected with 0.01mL Astragalus in Sanzuli acupoint per day,The saline group mice received an injection of same amount of saline. SOD,HYP and MDA changes in the skin tissue and serum were evaluated after 21 days. Results All the index in the skin tissue and serum showed significant difference(P<0.01)between model group mice and normal control group. Compared with model group,SOD activity and MDA content in the skin tissue and serum of the Astragalus group mice were significantly raised,HYP content was significantly reduced (P<0.01). There also were significant differences of these index between the saline group mice and the model group(P<0.05),but the effect was not as good as the Astragalus group mice. Conclusion Acupoint Injection of Astragalus can prevent and protect against skin aging induced by D-galactose.
ABSTRACT
Objective To explore the therapeutic effect and the mechanism of allicin on experimental Behcet′s disease (BD) . Methods BD models were established .Then ,model mice were randomly divided into experimental group ,positive control group and negative control group ,with respectively nasogastric infusion allicin ,colchicine and saline respectively .Before and after treatment , the changes of the skin lesions were visually observed .Cytokines of IFN‐γ,TNF‐αand IL‐4 in serum were detected by ELISA anal‐ysis ,while the markers of T‐AOC ,MDA ,SOD and GSH‐PX by chemical colorimetric methods .Results After modeling ,ulcers ap‐peared on the back ,abdomen and genital of model mice with IFN‐γ,TNF‐α,IL‐4 and MDA elevation ,while T‐AOC ,SOD and GSH‐PX decrease .Twenty days of treatment later ,ulcer on mice in the experimental group and positive control group healed .After 30 days ,only two mice in the experimental group recurred ,while 6 mice in the positive control group ,which showed a significant differ‐ence between two groups (P0 .05) .Meanwhile ,T‐AOC ,SOD and GSH‐PX levels in the experimental group were significantly higher than those in the pretreatment ,but MDA was lower (P<0 .01) .In comparison with the positive control group ,levels of those markers in the experimental group changed remark‐ably (P<0 .05) .Conclusion Allicin is an effective drug in the treatment of experimental BD .The therapeutic mechanism of allicin may be the inhibition of inflammatory mediators and prevention of oxidative stress .
ABSTRACT
BACKGROUND: The expression of matrix metalloproteinases (MMPs) is enhanced in fibroblasts of aging skin; tripterine and ginsenoside Rd possess immunosuppression and anti-aging effects. Arotinoid ethyl ester can used to treat sun-induced aging skin, which accompanied by many side effects, OBJECTIVE: To discuss the regulation role of ginsenoside Rd, celastrol, arotinoid ethyl ester on MMP-1 and MMP-3 of the cultured fibroblasts of the human dermis in vitro. METHODS: The human dermis circumcision by surgical excision on newborn was obtained from Department of Surgery, Luzhou Medical College, and the informed consent obtained from patients. Culture of fibroblasts were as follow: ①No treatment in the normal control group. ②Radiated with 80 kJ/m~2 ultraviolet and treated by 100mg/L8-methoxypsoralen in the positive control group. ③Treated by ultraviolet radiation+8-methoxypsoralen+arotinoid ethyl ester in the arotinoid ethyl ester group. ④Treated by ultraviolet radiation +8-methoxypsoralen+triptolide in the triptolide group. ⑤Treated byultraviolet radiation+8-methoxypsoralen+ginsenoside Rd in the ginsenoside Rdgroup. The triptolide group was divided into 3 groups with doses of 10, 20, and 40 mg/L. The ginsenoside Rd group was divided into 3 groups with doses of 20, 50 and 100 mg/L. The immunohistochemistry staining of MMP-1 and MMP-3 of the fibroblasts in each group was observed. RESULTS and CONCLUSION: The expressions of MMP-1 and MMP-3 were significantly increased in the positive control group, which had a significant difference to the normal control group (P < 0.05). Compared to the positive control group, the expression of MMP-1 and MMP-3 significantly decreased in the treatment groups (P < 0.05); however, the differences among each treatment groups had no significance (P > 0.05). The results demonstrated that:①Ginsenoside Rd and tripterine exhibit comparably effect on prevent and cure sun-induced aging skin.②The wide ranges of effective concentration lead to little side effect to the body. ③The action mechanisms of ginsenoside Rd, celastrol and arotinoid ethyl ester in preventing and curing sun-induced aging skin is adjusting the expressions of MMP-1 and MMP-3.
