RESUMEN
Objective:To evaluate clinical efficacy and safety of topical compound oleum lithospermi in the treatment of mild to moderate diaper dermatitis.Methods:A multicenter, randomized, positive-drug parallel-controlled clinical trial was conducted in 19 hospitals from July 2019 to August 2020. Children aged 0 - 12 months with mild to moderate diaper dermatitis were enrolled and randomly divided into 2 groups using a random number table: test group topically treated with compound oleum lithospermi, and control group topically treated with zinc oxide cream. The treatment was carried out 6 - 8 times a day for 7 days. Visits were scheduled on days 0 and 7, and total response rate and clinical healing time were evaluated. Changes in the dermatitis family impact (DFI) score were compared between the test group and control group, and adverse events were recorded. Statistical analysis was carried out by using independent-sample t test for normally distributed continuous data, Wilcoxon rank sum test for non-normally distributed continuous data, and chi-square test or Fisher′s exact test for unordered categorical data; survival curves were drawn, and log-rank test was used for comparisons between two groups. Results:A total of 343 children with diaper dermatitis were enrolled in this study. Among them, 31 children violated the protocol, so 312 were included in the per protocol set, including 157 in the test group and 155 in the control group, and all completed the visits on days 0 and 7. The total response rate was significantly higher in the test group (87.26%, 137/157) than in the control group (78.71%, 122/155; χ2 = 4.04, P = 0.044) . The clinical healing time was significantly shorter in the test group (5.33 days) than in the control group (6.13 days; χ2 = 4.67, P = 0.025) . After 7-day treatment, the DFI score significantly decreased in both the 2 groups compared with that before the treatment, but there was no significant difference in the DFI score between the 2 groups (test group: 4.02 ± 6.96, control group: 3.58 ± 5.90, Z = -0.39, P = 0.686) . The incidence of adverse events was 2.92% (5/171) and 5.45% (9/165) in the test group and control group respectively, and there was no significant difference between the 2 groups ( χ2 = 0.03, P = 0.865) . Conclusion:Compound oleum lithospermi can markedly reduce the clinical severity of diaper dermatitis, improve the total response rate, shorten the clinical treatment period, and improve the quality of life of children′s families with a favorable safety profile.

RESUMEN
Objective To evaluate the roles of Toll-like receptor 2 (TLR2),TLR4 and myeloid differentiation factor 88 (MyD88) in immune recognition and immune mediation in sporotrichosis by detecting their expressions in skin lesions of sporotrichosis.Methods Biopsy specimens were obtained from the skin lesions of 19 patients with sporotrichosis and normal skin of 12 healthy human controls.Immunohistochemistry was performed to observe the expressions of TLR4 and MyD88,and real-time fluorescence-based quantitative PCR to quantify the expressions of TLR2 and MyD88 mRNAs.Data were expressed as mean ± standard error.Statistical analysis was done with the SPSS17.0 software.Independent samples t-test was conducted to compare the parameters between the lesional and control specimens.A p-value of less than 0.05 was considered to be statistically significant.Results TLR4 and MyD88 were mainly observed in the whole epidermis except the stratum corneum as well as plasma cells and lymphocytes in the dermis and subcutaneous tissue in lesional skin.However,TLR4 was nearly absent and MyD88 was weakly expressed in the dermis and subcutaneous tissue in normal skin.The expression levels of TLR4 and MyD88 were significantly higher in the lesional skin than in the control skin (TLR4,63.767 ± 3.829 vs.5.167 ± 3.246,t =4.82,P ＜ 0.05; MyD88,57.236 ± 4.744 vs.10.588 ± 1.640,t =3.30,P ＜ 0.05).Similarly,the lesional skin showed significantly stronger expressions of TLR2 and MyD88 mRNAs compared with the normal skin (TLR2,1.974 ± 1.452 vs.1.430 ± 1.073,P ＜ 0.05; MyD88,2.028 ± 2.061 vs.0.688 ± 0.422,P ＜ 0.05).Conclusion Sporothrix may induce the development of sporotrichosis by interacting with host immune system via TLR signaling pathways.
RESUMEN
ObjectiveTo investigate the roles of Toll-like receptor (TLR) 3 and 9 in herpes zoster (HZ).Methods Venous blood samples were collected from 40 patients with HZ and 16 normal human controls. Flow cyometrywas usedto detect the expressionsof TLR3and TLR9inperipheralblood mononuclear cells(PBMCs) from these subjects.ResultsThe percentages of PBMCs expressing TLR3 and TLR9 were significantly higher in patients than in normal human controls(both P ＜ 0.01).The expression levels of TLR3 and TLR9 in PBMCs were negatively correlated with the age of onset(r =-6.23,-5.88respectively,both P ＜ 0.01 ),but uncorrelated with gender or age.There was a significant difference in the expression levels of TLR3 and TLR9 in PBMCs between different age groups ( ＜ 40 years,40-50 years,＞ 50 years) of patients with HZ(F =3.410,P ＜ 0.01 ),with the strongest expression observed in patients younger than 40 years.ConclusionTLR3 and TLR9 may participate in the pathogenesis of HZ.

ObjectiveTo explore the roles of Toll-like receptor (TLR) 3,7 and 9 in the pathogenesis of pityriasis rosea.MethodsThis study recruited 40 patients with pityriasis rosea and 40 normal human controls.Reverse transcription-PCR was carried out to detect the expressions of TLR3,7 and 9 in peripheral blood lymphocytes of these subjects.ResultsThe mRNA expressions of TLR3,7 and 9 in peripheral blood lymphocytes were significantly higher in patients with pityriasis rosea than in the normal human controls (Z =4.239,3.745,2.658,all P ＜ 0.05).There was a positive correlation between the expression of TLR3 and TLR7(r =0.574,P ＜ 0.01 ) as well as between that of TLR3 and TLR9 (r =0.551,P ＜ 0.01 ) in the patients,while there was no correlation between TLR7 and TLR9 expression in the patients or between the expressions of TLR3,TLR7 and TLR9 in the controls.ConclusionVirus infection might be involved in the pathogenesis of pityriasis rosea via TLR pathways.
RESUMEN
Objective To investigate the location of TLR3 and TLR9 protein as well as the expressions of TLR3 and TLR9 protein and mRNA in the lesions of condyloma acuminatum (CA) with different prognosis. Methods Immunocytochemical staining with streptavidin-peroxidase (SP) and reverse transcription (RT)-PCR were conducted to detect the expressions of TLR3 and TLR9 in tissue specimens from lesions of 10 patients with recurrent CA, 14 patients with non-recurrent CA as well as from the foreskin of 10 normal human controls. Results TLR3 and TLR9 were mainly distributed in spinous layer and granular layer in non-recurrent CA lesions, but in basal layer and spinous layer in recurrent CA lesions. A significant elevation was observed in the expression of TLR3 mRNA in non-recurrent CA lesions compared with the control tissue and recurrent CA lesions (P < 0.01, 0.05), and in the expression of TLR9 mRNA in non-recurrent CA lesions compared with the control tissue (P < 0.05). No significant difference was observed between the recurrent and non-recurrent CA lesions in the expression of TLR9 mRNA. Conclusions The changes in the distribution and expressions of TLR3 and TLR9 in epidermis may be associated with the prognosis of CA, and TLR3 may exert a greater impact.
