This analysis evaluates the efficacy of tamanu oil in acne treatment with a specific focus on its impact on inflammation and scar reduction. The novelty of this research lies in its comprehensive analysis of tamanu oil’s dual mechanism of action: reducing acne-related inflammation and promoting the healing of acne scars. Clinical trials and laboratory analyses were conducted to assess the oil’s effectiveness in diminishing erythema, swelling, and post-acne scarring compared to conventional treatments. Preliminary findings demonstrate that tamanu oil significantly reduces inflammation and accelerates wound healing, potentially offering a promising adjunct or alternative to standard acne therapies. Future research should aim to optimize formulation and application protocols, long-term effects, and comparative therapeutic efficacy with other anti-inflammatory agents. Tamanu oil offers a novel and effective approach to acne management, with potential advantages that go beyond inflammation reduction to include enhanced scar reduction, making it a subject that warrants further investigation.展开更多

Two hundred and fifty-four Korean adolescents were asked to complete the Korean version of the CADI(K-CADI), the Phlegm Pattern, the Cold-Heat Pattern, and the Korean version of the General Health Questionnaires. A clinician estimated acne severity for the adolescents, using the Korean Acne Grading System. Finally, reliability and validity of the K-CADI was examined, and the relationships between acne severity, Phlegm, Cold, and Heat patterns, and Qo L level were examined via pathway analysis.RESULTS: The K-CADI had satisfactory internal consistency(α = 0.827). The examination of construct validity indicated that the K-CADI had one factor(explaining 59.6% of the total variance). Pathway analysis showed satisfactory model fit(normal fit index = 0.960 and comparative fit index = 0.983),and acne-related Qo L was determinant to Phlegm,Heat, and Cold patterns(0.13-0.27 of β), and Phlegm and Heat patterns lowered one's Qo L level(0.17-0.34 of β).CONCLUSION: The K-CADI is a valid and reliable instrument. Phlegm and Heat patterns should be managed when treating acne since they have a moderating effect on general Qo L aggravation.展开更多

Alternative solutions to acne treatment were instigated by antibiotic resistance despite of its extensive use. Purified bee venom （PBV） has been proposed as a promising candidate for that purpose. The present study was designed to confirm the antibacterial effect of PBV and access the efficacy of cosmetics containing PBV in subjects with acne vulgaris. METHODS： The skin bacterium Propionibacterium acnes was incubated with PBV at various concentrations and bacterial growth was evaluated using the colony forming unit （CFU） assay. The mechanism of PBV employed in killing P. acnes was examined by scanning electron microscopy （SEM） and transmission electron microscopy （TEM）. In addition, a total of 12 subjects were randomized in a double-blind, controlled trial to receive either cosmetics containing PBV or cosmetics without PBV for two weeks. Evaluations included lesion counts and skin microorganism. RESULTS： PBV exhibited antimicrobial activity in a concentration-dependent manner, reducing the number of P. acnes CFU by approximately 6 logs at a concentration of 0.5 mg. When PBV concentration was higher than 1.0 mg, no P. acnes colonies were spotted on an agar. TEM and SEM of untreated P. acnes illustrated the normal pleomorphic structure, whereas the PBV- treated bacterium lost the integrity of surface architecture. Significant difference （P=0.027） in the grading levels based on numbers of lesion counts for inflammatory and noninflammatory was observed in favour of the PBV group compared with the control group. In terms of average decrement of skin microorganism, subjects receiving cosmetics containing PBV experienced a significant 57.5% decrease of adenosine triphosphate levels, whereas participants receiving cosmetics without PBV experienced a nonsignificant decrease of 4.7%. CONCLUSION： These results show that the in vitro actions of antimicrobial activity of PBV were translated in vivo. Cosmetics containing PBV provided a certain degree of efficacy in terms of lesion counts and skin microorganism concentration compared with cosmetics without PBV in subjects with acne vulgaris. PBV may be a good candidate compound for developing therapeutic drua for the treatment of acne vulaaris.展开更多

Fractional radiofrequency technologies have been shown to be clinically safe and effective in managing acne scars through dermal remodeling without causing direct damage to the epidermis. In a recently published study, we presented our clinical and histological results in the treatment of patients with active acne and acne related scarring using a Fractional RF (FRF) device. In the current article we demonstrate long term follow-up results, up to two years post last fractional treatment. Methods: Four out of the eight patients who completed a four treatment regimen were invited for long term follow-up visit to document treatment results. In some cases, touch-up treatments were conducted to optimize clinical results. Results: Patients demonstrated significant improvement of acne lesions, acne scarring, pores and skin texture. Long term photos demonstrated that clinical improvement progressed with time. Conclusion: The current study further supports the previous findings that FRF is a safe and effective treatment modality for active acne and acne related scars. Treatment protocol can be customized according to patient needs and clinical results last for long term.展开更多

Clinical effect was observed after 8 times of treatment. Results Among 67 cases, 42 cases were cured, 21 cases were markedly effective, and 4 cases were effective. The cured rate was 62.69%, and the cured and markedly effective rate was 94.03%. Conclusion The fire needling and pricking bloodletting has a significant effect in the treatment of acne vulgaris with high cured rate, worthy of clinical promotion
文摘OBJECTIVE: To culturally translate the cardiff acne disability index(CADI) into Korean, and to examine its relationship with clinical acne severity,pathological patterns, and general quality of life(Qo L).METHODS: The CADI was culturally and lin-guistically translated into Korean via translation,back-translation, and face validity test process. Two hundred and fifty-four Korean adolescents were asked to complete the Korean version of the CADI(K-CADI), the Phlegm Pattern, the Cold-Heat Pattern, and the Korean version of the General Health Questionnaires. A clinician estimated acne severity for the adolescents, using the Korean Acne Grading System. Finally, reliability and validity of the K-CADI was examined, and the relationships between acne severity, Phlegm, Cold, and Heat patterns, and Qo L level were examined via pathway analysis.RESULTS: The K-CADI had satisfactory internal consistency(α = 0.827). The examination of construct validity indicated that the K-CADI had one factor(explaining 59.6% of the total variance). Pathway analysis showed satisfactory model fit(normal fit index = 0.960 and comparative fit index = 0.983),and acne-related Qo L was determinant to Phlegm,Heat, and Cold patterns(0.13-0.27 of β), and Phlegm and Heat patterns lowered one's Qo L level(0.17-0.34 of β).CONCLUSION: The K-CADI is a valid and reliable instrument. Phlegm and Heat patterns should be managed when treating acne since they have a moderating effect on general Qo L aggravation.

文摘Acne vulgaris is a chronic dermatologic problem with multiple factors involved in its pathogenesis. Alternative solutions to acne treatment were instigated by antibiotic resistance despite of its extensive use. Purified bee venom （PBV） has been proposed as a promising candidate for that purpose. The present study was designed to confirm the antibacterial effect of PBV and access the efficacy of cosmetics containing PBV in subjects with acne vulgaris. METHODS： The skin bacterium Propionibacterium acnes was incubated with PBV at various concentrations and bacterial growth was evaluated using the colony forming unit （CFU） assay. The mechanism of PBV employed in killing P. acnes was examined by scanning electron microscopy （SEM） and transmission electron microscopy （TEM）. In addition, a total of 12 subjects were randomized in a double-blind, controlled trial to receive either cosmetics containing PBV or cosmetics without PBV for two weeks. Evaluations included lesion counts and skin microorganism. RESULTS： PBV exhibited antimicrobial activity in a concentration-dependent manner, reducing the number of P. acnes CFU by approximately 6 logs at a concentration of 0.5 mg. When PBV concentration was higher than 1.0 mg, no P. acnes colonies were spotted on an agar. TEM and SEM of untreated P. acnes illustrated the normal pleomorphic structure, whereas the PBV- treated bacterium lost the integrity of surface architecture. Significant difference （P=0.027） in the grading levels based on numbers of lesion counts for inflammatory and noninflammatory was observed in favour of the PBV group compared with the control group. In terms of average decrement of skin microorganism, subjects receiving cosmetics containing PBV experienced a significant 57.5% decrease of adenosine triphosphate levels, whereas participants receiving cosmetics without PBV experienced a nonsignificant decrease of 4.7%. CONCLUSION： These results show that the in vitro actions of antimicrobial activity of PBV were translated in vivo. Cosmetics containing PBV provided a certain degree of efficacy in terms of lesion counts and skin microorganism concentration compared with cosmetics without PBV in subjects with acne vulgaris. PBV may be a good candidate compound for developing therapeutic drua for the treatment of acne vulaaris.

文摘Objective Proprionibacterium acnes(P.acnes)-induced inflammatory responses,proliferation and differentiation of keratinocytes contribute to the progression of acne vulgaris(AV).P.acnes was found to enhance the production of interleukin-8(IL-8)by keratinocytes.This study aimed to investigate the role of IL-8 in P.acnes-induced proliferation and differentiation of keratinocytes and the underlying mechanism.Methods The P.acnes-stimulated HaCaT cell(a human keratinocyte cell line)model was established.Western blotting and immunofluorescence were performed to detect the expression of the IL-8 receptors C-X-C motif chemokine receptor 1(CXCR1)and C-X-C motif chemokine receptor 2(CXCR2)on HaCaT cells.Cell counting kit-8(CCK-8)assay,5-ethynyl-20-deoxyuridine(EdU)assay and Western blotting were performed to examine the effects of IL-8/CXCR2 axis on the proliferation and differentiation of HaCaT cells treated with P.acnes,the IL-8 neutralizing antibody,the CXCR2 antagonist(SB225002),or the CXCR1/CXCR2 antagonist(G31P).Western blotting,nuclear and cytoplasmic separation,CCK-8 assay,and EdU assay were employed to determine the downstream pathway of CXCR2 after P.acnes-stimulated HaCaT cells were treated with the CXCR2 antagonist,the protein kinase B(AKT)antagonist(AZD5363),or the constitutively active forkhead box O1(FOXO1)mutant.Finally,autophagy markers were measured in HaCaT cells following the transfection of the FOXO1 mutant or treatment with the autophagy inhibitor 3-methyladenine(3-MA).Results The expression levels of CXCR1 and CXCR2 were significantly increased on the membrane of HaCaT cells following P.acnes stimulation.The IL-8/CXCR2 axis predominantly promoted the proliferation and differentiation of P.acnes-induced HaCaT cells by activating AKT/FOXO1/autophagy signaling.In brief,IL-8 bound to its receptor CXCR2 on the membrane of keratinocytes to activate the AKT/FOXO1 axis.Subsequently,phosphorylated FOXO1 facilitated autophagy to promote the proliferation and differentiation of P.acnes-induced keratinocytes.Conclusion This study demonstrated the novel autocrine effect of IL-8 on the proliferation and differentiation of P.acnes-induced keratinocytes,suggesting a potential therapeutic target for AV.
文摘Introduction: Acne vulgaris and acne scarring are prevalent conditions that can have a negative effect on a patient’s quality of life. Fractional radiofrequency technologies have been shown to be clinically safe and effective in managing acne scars through dermal remodeling without causing direct damage to the epidermis. In a recently published study, we presented our clinical and histological results in the treatment of patients with active acne and acne related scarring using a Fractional RF (FRF) device. In the current article we demonstrate long term follow-up results, up to two years post last fractional treatment. Methods: Four out of the eight patients who completed a four treatment regimen were invited for long term follow-up visit to document treatment results. In some cases, touch-up treatments were conducted to optimize clinical results. Results: Patients demonstrated significant improvement of acne lesions, acne scarring, pores and skin texture. Long term photos demonstrated that clinical improvement progressed with time. Conclusion: The current study further supports the previous findings that FRF is a safe and effective treatment modality for active acne and acne related scars. Treatment protocol can be customized according to patient needs and clinical results last for long term.
