RESUMEN

OBJECTIVE@#To elucidate the mechanisms of 4 effective components from a Chinese medicine formula, namely Qingre Huoxue Jiedu Formula (QHJ heat- and toxin-clearing and blood-activating formula), in the treatment of nerve growth factor (NGF)-induced psoriasis.@*METHODS@#Keratinocyte proliferation and T cell proliferation models were developed using NGF. An NGF solution (NGF+DMEM, 100 ng/mL) was added to all induced groups and treated groups and were cultured for 24 h, while a solution with NTRK1 antagonist (K252a+DEME, 300 nmol/L) was added and cultured for 1 h. The models were used to evaluate the effects of the treatment with each of the 4 components of QHJ, namely shikonin, paeonol, astilbin and ursolic acid. Cell apoptosis and proliferation were measured by flow cytometry analysis and CCK8 assay, respectively. The mRNA expression levels of Bax, Bcl-xl, and NGF receptor (NGFR) were assessed by quantitative real-time PCR (qRT-PCR) and Western blot analysis, respectively.@*RESULTS@#(1) All QHJ-treated groups showed significantly increased cell apoptosis and inhibition of cell proliferation compared with the NGF-induced groups (P<0.05). In addition, treatment with QHJ plus NTRK1 significantly enhanced cell apoptosis and inhibition of cell proliferation compared with cells treated with QHJ only (P<0.05), particularly in cells treated with ursolic acid. (2) QHJ-treated groups showed higher protein expression levels of Bax, Bcl-xl compared with other groups (P<0.05). Additionally, treatment with QHJ plus NTRK1 significantly increased the protein expression levels of Bax, Bcl-xl and NGFR compared with those treated with QHJ only (all P<0.05), especially in those treated with shikonin.@*CONCLUSION@#The action mechanism of QHJ on psoriasis might be through enhancing cell apoptosis and inhibition of cell proliferation, and upregulating the expression level of Bax, Bcl-xl and NGFR.

RESUMEN

<p><b>OBJECTIVE</b>To observe the clinical efficacy of narrow band ultraviolet bin (NB-UVB) combined with Yuyin Recipe (YYR) in treating psoriasis vulgaris (PV).</p><p><b>METHODS</b>One hundred and nineteen patients with PV were randomly assigned to 2 groups by envelop method, the 62 patients in the treated group were treated with NB-UVB and YYR bathing, and the 57 in the control group were treated with NB-UVB alone. The course of treatment for both groups was 8 weeks. PASI scoring was performed before treatment and at the 2nd, 4th, 6th and 8th week of treatment respectively, and the treatment effect was evaluated depending on the decreasing rate of PASI score. The accumulated dose and side-effect of NB-UVB applied was observed.</p><p><b>RESULTS</b>The PASI scores in the treated group measured at various time points after treatment were significantly different to that of baseline (P < 0.05). The cure rate in the treated group and the control group was 69.35% and 24.56% while the total effective rate in them 96.77% and 71.93%, respectively, showing significant difference between the two groups (chi2 = 27.755, P <0.01). The difference of PASI decreasing rate between groups showed statistical significant from the 4th week (P <0.01). The total dose of NB-UVB applied in the treated group (9.95 +/- 4.76) was less than that in the control group (12.77 +/- 5.05) with the difference of statistical significance (t = 3.141, P <0.01). The adverse reaction occurrence in them was 4.84% (3/62) and 31.58% (18/57) respectively, also showing significant difference (chi2 = 119, P <0.01). CCONCLUSION: The combined use of TCM medicated bath with NB-UVB can enhance the curative effect, reduce the accumulated dosage and lessen the adverse reactions of ultraviolet radiation.</p>

RESUMEN

<p><b>OBJECTIVE</b>To investigate the clinical efficacy of compound periploca liquid (CPL) in treating condyloma acuminatum (CA), and to explore its mechanisms at molecular level.</p><p><b>METHODS</b>Eighty-one patients with CA were randomly divided into three groups, 30 patients in Group A were treated with CPL, 21 in Group B were treated with periploca syrup and 30 in Group C were treated with Youtuoxin (YXG). The clinical efficacy and adverse reaction occurred in the three groups was evaluated respectively. Besides, change of human papilloma virus (HPV) DNA in two patients with CA was determined by polymerase chain reaction (PCR) in vitro after being treated with CPL and periploca, the monarchic drug of CPL.</p><p><b>RESULTS</b>The cure rate obtained in group A, B, and C was 56.67%, 42.86% and 63.33% respectively, the total effective rate in them was 83.33%, 71.43% and 86.67% respectively, the difference of therapeutic efficacy was insignificant among the three groups. But the adverse reaction occurrence in them (6.67%, 4.76% and 86.67%) was significantly different (P < 0.01). The recurrent rate in them was 14.29%, 12.5% and 47.1% respectively. PCR showed negative expression of HPV in the two samples of CA of same concentration after the verrucous homogenate suspension being treated with CPL or periploca syrup of different concentration, while it was positive after the suspension was treated with the group of normal saline without any drug.</p><p><b>CONCLUSION</b>The therapeutic efficacies of CPL, periploca syrup and Youtuoxin are not significantly different, but the former two have advantages of less adverse effects and lower recurrent rate. And they are possibly having germicidal action on HPV-DNA in CA tissue in vitro.</p>
