A Systematic Study of Yiqi Qubai Standard Decoction for Treating Vitiligo Based on UPLC-Q-TOF/MS Combined with Chemometrics, Molecular Docking, and Cellular and Zebrafish Assays. Pharmaceuticals (Basel) 2023; 16:1716. [PMID: 38139842 PMCID: PMC10747336 DOI: 10.3390/ph16121716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Revised: 11/27/2023] [Accepted: 12/07/2023] [Indexed: 12/24/2023] Open
Abstract
The Yiqi Qubai (YQ) formula is a hospital preparation for treating vitiligo in China that has had reliable efficacy for decades. The formula consists of four herbs; however, the extraction process to produce the formula is obsolete and the active ingredients and mechanisms remain unknown. Therefore, in this paper, fingerprints were combined with the chemometrics method to screen high-quality herbs for the preparation of the YQ standard decoction (YQD). Then, the YQD preparation procedure was optimized using response surface methodology. A total of 44 chemical constituents, as well as 36 absorption components (in rat plasma) of YQD, were identified via UPLC-Q-TOF/MS. Based on the ingredients, the quality control system of YQD was optimized by establishing the SPE-UPLC-Q-TOF/MS identification method and the HPLC quantification method. Network pharmacological analysis and molecular docking showed that carasinaurone, calycosin-7-O-β-d-glucoside, methylnissolin-3-O-glucoside, genkwanin, akebia saponin D, formononetin, akebia saponin B, and apigenin may be the key active components for treating vitiligo; the core targets associated with them were AKT1, MAPK1, and mTOR, whereas the related pathways were the PI3K-Akt, MAPK, and FoxO signaling pathways. Cellular assays showed that YQD could promote melanogenesis and tyrosinase activity, as well as the transcription and expression of tyrosinase-associated proteins (i.e., TRP-1) in B16F10 cells. In addition, YQD also increased extracellular tyrosinase activity. Further efficacy validation showed that YQD significantly promotes melanin production in zebrafish. These may be the mechanisms by which YQD improves the symptoms of vitiligo. This is the first systematic study of the YQ formula that has optimized the standard decoction preparation method and investigated the active ingredients, quality control, efficacy, and mechanisms of YQD. The results of this study lay the foundations for the clinical application and further development of the YQ formula.

Abstract
To investigate the effect of human adipose tissue-derived multilineage-differentiating stress-enduring (Muse) cells on the oxidative stress injury of human epidermal melanocytes (HEMs) in vitro. HEMs were treated with H2O2 to establish an oxidative stress injury model and then were co-cultured with adipose tissue-derived Muse cells. Immunohistochemistry, flow cytometry and Western blotting were used to assess changes in autophagy flux, apoptosis, expression of melanin synthesis related proteins and proliferation of melanocytes. Our findings demonstrate that co-culture with Muse cells significantly increased the tolerance of HEMs to oxidative stress, enhanced autophagy flux and reduced apoptosis. The expression of proteins related to the formation of melanin increased as did cell proliferation. Treatment with the autophagy inhibitor, 3-methyladenine (3MA), partially counteracted the improvement of oxidative stress tolerance in melanocytes elicited by co-culture with Muse cells. Muse cells promote autophagy and oxidative stress tolerance of melanocytes.

Reduced Elastin Fibers and Melanocyte Loss in Vitiliginous Skin Are Restored after Repigmentation by Phototherapy and/or Autologous Minigraft Transplantation. Int J Mol Sci 2022; 23:ijms232315361. [PMID: 36499690 PMCID: PMC9739647 DOI: 10.3390/ijms232315361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Accepted: 12/01/2022] [Indexed: 12/12/2022] Open
Abstract
Vitiligo is a hypopigmentation disease characterized by melanocyte death in the human epidermis. However, the mechanism of vitiligo development and repigmentation is largely unknown. Dermal fiber components might play an important role in vitiligo development and repigmentation. Indeed, our preliminary study demonstrated that elastin fibers were decreased in vitiliginous skin, suggesting that the elastin fiber is one of the factors involved in vitiligo development and repigmentation. To confirm our hypothesis, we investigated whether elastin fibers can be restored after treatment using phototherapy and/or autologous skin transplantation. Punch biopsies from 14 patients of stable nonsegmental vitiligo vulgaris were collected from nonlesional, lesional, and repigmented skin, and processed to dopa and combined dopa-premelanin reactions. Melanocytes positive to the dopa reaction and melanoblasts/melanocytes positive to the combined dopa-premelanin reaction were surveyed. Moreover, elastin fibers were detected by Victoria blue staining. Numerous melanocytes and melanoblasts were observed in the epidermis of repigmented skin after the treatment. Moreover, in the dermis of repigmented skin, elastin fibers were completely recovered or even upregulated. These results suggest that melanocyte loss in the vitiliginous skin, as well as melanocyte differentiation in repigmented skin, may be at least in part regulated by elastin fibers in the dermis.

Abstract
Background Vitiligo is the most common depigmentation disorder. This disease causes disfiguration and induces psychological burdens, leading to significantly impaired quality of life. Limited research about disease-related post-traumatic stress (PTS) has been conducted in vitiligo patients. Objective To evaluate the prevalence, severity, and risk factors of post-traumatic stress in vitiligo patients. Methods This case-control study was performed from January 2021 to April 2021. A survey questionnaire including baseline information, post-traumatic stress symptoms evaluation, life quality evaluation was conducted. According to the severity of post-traumatic stress symptoms, patients were grouped and compared. The logistic regression model was conducted to analyze the risk factors for post-traumatic stress disorder (PTSD). Results A total of 337 patients were included. A 30.3% of vitiligo patients (102/337) in present cohort had PTS and 12.5% patients (42/337) were confirmed for developing into PTSD. The multivariate logistic regression revealed educational level<university (OR=2.32, 95% CI=1.97–2.93, P=0.003), vitiligo in face and neck (OR=2.65, 95% CI=2.08–3.12, P=0.008), vitiligo in feet and hands (OR=1.86, 95% CI=1.54–2.12, P<0.001) and surgical treatment (OR=3.53, 95% CI=3.12–4.02, P<0.001) were risk factors for PTSD. PTS severity was significantly associated with vitiligo disease activity score (rho=0.54, R2=0.29, P=0.002), vitiligo area scoring index score (r=0.55, R2=0.30, P=0.012), and dermatology life quality index score (r=0.61, R2=0.37, P=0.004). Conclusion Vitiligo-related PTS is prevalent in vitiligo patients and causes psychological impairment. Dermatologists should realize and identify this condition carefully and offer proactive intervention to improve patients’ quality of life.

Abstract
Although surgical interventions have become optional for refractory vitiligo, grafting related injuries is inevitable. Embryonic stem cell (ESC) derivatives can be used in transplantation to address this issue, but the immune rejection due to allogeneic transplantation is of great concern. To investigate the immunogenicity of ESC derived melanocytes (ES-MC), we established a co-culture system of ES-MC and allogeneic PBMC. The results showed that ES-MC were similar to human primary melanocytes, with low expression of immune related molecules, and limited capability of stimulating allogeneic lymphocytes in vitro. Taken together, our findings confirm that ES-MC are of limited immunogenicity, providing new insights into the application of ES-MC in the regenerative medicine such as treating vitiligo.

Abstract
Background Repigmentation remains the primary target in vitiligo treatment. Melanocyte transfer procedures are often required for repigmenting stable, resistant vitiligo lesions necessitating procedural optimization and comparative evaluation. In the current study, we aimed to assess the additive value of weekly transverse needling sessions after mini-punch grafting for repigmenting stable non-segmental vitiligo lesions versus either procedure alone. Methods Eighty lesions, included in 20 stable non-segmental vitiligo patients, were randomly allocated to each of the three treatment groups (line-1, mini-punch grafting; line-2, needling; and line-3, combined grafting and needling) and to a fourth control group receiving non-procedural treatment (line-4). Oral mini-pulse steroids and narrow-band ultraviolet-B sessions were administered to all patients for 3 months before and 6 months after the interventions. The extent of repigmentation was assessed using planimetry. Secondary outcomes were the time to first repigmentation response, cosmetic matching, and patient satisfaction. Blinding and allocation concealment were not feasible owing to the intervention nature and within subject design. Results Mini-punch grafting followed by weekly needling for 6 months achieved the fastest response and highest extent of repigmentation. Mini-punch grafts and transverse needling alone provided better results than the control group. No steroid-associated side effects were reported. Conclusion Weekly needling sessions after mini-punch grafting hastened and improved the repigmentation extent of stable, resistant, non-segmental vitiligo lesions and should be considered during treatment planning.

Abstract
Topical Tacrolimus, especially when combined with Nb-UVB, has been proven clinically to be effective in the treatment of vitiligo. However, no histological study has evaluated the repigmentation mechanism of tacrolimus ointment in combination therapy with Nb-UVB. In this study, the histological findings in patients receiving Nb-UVB were compared with those receiving topical tacrolimus combined with Nb-UVB. Twenty patients were recruited and received Nb-UVB treatment. The first ten patients were selected for the combination therapy and instructed to apply tacrolimus 0.1% ointment twice daily on the specified lesion of interest. The remaining ten patients did not receive any other topical treatments. Skin biopsy was performed at baseline from the depigmented area and 2-3 months post-treatment from the repigmented area. Biopsy specimens were stained with haematoxylin-eosin-safran (HES), Fontana Masson, HMB45, Melan A, MITF, SOX10 and Nestin. Clinically, in the combination therapy group, interfollicular repigmentation in addition to the perifollicular and marginal pattern was observed. Histologically, in the combination therapy group, besides the migration of melanocytes from the bulge of the hair follicle seen in the monotherapy group, for the first time, we observed dermal melanocyte precursors located in mid- and superficial dermis.
