RESUMEN
OBJECTIVE: To explore the distribution law of traditional Chinese medicine (TCM) syndrome types in patients with psoriasis vulgaris complicated by metabolic disorders based on the same pathogenic factors as blood-heat and blood-stasis in the pathogenesis of psoriasis and metabolic disorders and to further analyze the correlation between adiponectin and the distribution law. METHODS: From 1 January 2018 to 31 December 2019, patients diagnosed with psoriasis in the inpatient or outpatient department of Dermatology Ward of Shanghai Yueyang Hospital and normal participants who underwent physical examination in the physical examination center over the same period were retrospectively reviewed. Demographic data, medical history, metabolic disorder indices, and TCM syndrome indices of psoriasis patients and healthy volunteers were evaluated. RESULTS: We included 307 patients with psoriasis and 613 healthy controls. On analyzing past medical history, the proportion of overweight and obesity and the comorbidity of diabetes in the psoriasis group (53.42 and 14.66%) were significantly higher than in the control group (43.88 and 7.67%, respectively; p < .05). The abnormal rates of triglyceride (34.20%), high-density lipoprotein cholesterol (50.49%), and HbA1c (18.57%) levels in the psoriasis group were higher than those in the normal control group (26.75, 17.13, and 12.56%, respectively). Overall, the incidence of metabolic disorders in psoriasis patients (267/307, 86.97%) was higher than that in the normal controls (484/613, 78.96%). Among the different syndrome types, the blood-stasis group had significantly higher rates of hypertension, diabetes, and abnormal glycosylated hemoglobin (46.07, 19.10, and 24.72%, respectively) than those of the control group (27.57, 7.67, and 12.56%; p < .05). Patients with blood stasis syndrome had the highest metabolic disorder comorbidity rate (93.26%) and lowest adiponectin level (p < .05). CONCLUSIONS: TCM syndrome differentiation of psoriasis, especially the diagnosis of blood-stasis syndrome, prompts the early screening of patients with metabolic comorbidities. For patients with psoriasis with metabolic disorder, TCM for promoting blood circulation and removing blood stasis can be compatibly applied without contraindications. TRIAL REGISTRATION: The trial was registered at ClinicalTrials.gov (Trial ID: NCT03942185).

Background: Traditional Chinese medicine is effective in the treatment of psoriasis and can significantly reduce skin inflammation and psoriatic lesions with minimal side effects. Shikonin (SHI) and ß,ß-dimethylacryloyl alkannin (DMA), the main active components of Lithospermum erythrorhizon, have strong anti-inflammatory effects. This systematic review aimed to evaluate the efficacy and safety of Lithospermum erythrorhizon and its main active components and to elucidate the potential mechanisms of their action in psoriasis treatment. Methods: PubMed, Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Chinese Scientific Journals, Wan Fang, and Chinese Biomedicine databases were systematically searched for articles published between 1 January 1970, and 31 February 2021. We included clinical and preclinical studies that examined the effects of Lithospermum erythrorhizon and its active components on psoriasis. All data were analyzed using RevMan 5.3 software. The Cochrane and SYRCLE's risk-of-bias tools were used to assess the quality of all studies. Results: Eleven clinical trials including 1024 participants and 23 preclinical studies were assessed. Meta-analysis showed that when treating patients with psoriasis, the Chinese herbal medicine (CHM) formulas with Lithospermum erythrorhizon as the sovereign herb can significantly improve psoriatic dermatitis, which can significantly reduce the psoriasis area and severity index (PASI) score (mean difference [MD] = -2.00, 95% confidence interval [CI] [-3.19, -0.80], p = 0.001; I2 = 85%). The incidence rates of diarrhea (risk ratio = 0.21, 95% CI [0.06, 0.81], p = 0.02) were higher in the CHM formulas group than in the control group, whereas other adverse events were not significantly different between the two groups (p > 0.05). We evaluated the PASI score of mice on day 7 and found that SHI and DMA also alleviated psoriatic lesions (MD = -3.36, 95% CI [-4.67, -2.05], p < 0.00001, I2 = 94%). Furthermore, the epidermal thickness decreased more after SHI or DMA treatment than in the control group (MD = -34.42, 95%CI [-41.25, -27.59], p < 0.00001, I2 = 93%). Based on preclinical studies, we also summarized and mapped the mechanisms of SHI and DMA in the treatment of psoriasis. Conclusion: Available findings demonstrated that Lithospermum erythrorhizon combined with other conventional treatments is useful in treating psoriasis. Preclinical evidence has shown that the active components of Lithospermum erythrorhizon exhibit a potential anti-inflammatory effect, promote keratinocyte apoptosis, inhibit keratinocyte proliferation and angiogenesis, and block the cell cycle. In summary, our findings suggest that Lithospermum erythrorhizon and its active components can be used to treat psoriasis.
RESUMEN
OBJECTIVE: Psoriasis is a common chronic inflammatory skin disease that is prone to recurrence, and the proinflammatory factor, cysteine-rich protein 61 (Cyr61), is important in its pathophysiology. Long-term clinical practice has shown that Sancao Formula (SC), a Chinese herbal compound, is effective in the treatment of psoriasis, but the precise mechanism remains unknown. In this study, we investigate the mechanism by which SC extract alleviates imiquimod (IMQ)-induced psoriasis. METHODS: The expression of Cyr61 in psoriatic lesions and normal healthy skin was detected using immunohistochemical analysis to investigate the biological role of Cyr61 in models of psoriatic inflammation. A psoriatic mouse model was established by topical application of IMQ, and the effect of topical application of SC extract was evaluated using the psoriasis area and severity index (PASI) score, hematoxylin-eosin staining, and histopathological features of the skin. Next, a HaCaT cell inflammation model was established using interferon-γ (IFN-γ), and the effect of SC extract on the mRNA and protein levels of Cyr61 and intercellular cell adhesion molecule-1 (ICAM-1) was confirmed using Western blot and quantitative real-time polymerase chain reaction analyses. RESULTS: Immunohistochemical staining showed that the expression of Cyr61 in psoriatic lesions was higher than that in normal skin samples (78.26% vs 41.18%, P < 0.05), and the number of Cyr61-positive cells in psoriatic lesions was also significantly higher than in normal skin (18.66 ± 2.51 vs 4.33 ± 1.52, P < 0.05). Treatment in mice with IMQ-induced psoriasis showed that SC extract could significantly improve the inflammatory phenotype, PASI score (10.875 ± 0.744 vs 3.875 ± 0.582, P < 0.05), and pathological features compared with those in IMQ model group; SC treatment was also associated with decreased levels of Cyr61 and ICAM-1. In the IFN-γ-induced inflammatory cell model, the mRNA and protein levels of Cyr61 and ICAM-1 were upregulated, while the SC extract downregulated the levels of Cyr61 and ICAM-1. CONCLUSION: The results provide a theoretical basis for the involvement of Cyr61 in the pathogenesis of psoriasis, and suggest that SC should be used to target Cyr61 for the prevention of psoriasis recurrence.

BACKGROUND: Quyu Shengji Formula (QSF), a Chinese medicine formula widely used in the clinic, has proven therapeutic effects on diabetic ulcers. Nevertheless, the potential mechanism of how QSF cures diabetic ulcer remains elusive. OBJECTIVE: To assess the mechanism of QSF against wound healing defects in diabetes. METHODS: Db/db mice were adopted to determine the therapeutic potential of QSF. Further histology analysis was performed by hematoxylin and eosin (H&E) staining. Moreover, the expression patterns of prostaglandin transporter (PGT), prostaglandin E2 (PGE2), and angiogenesis factor vascular endothelial growth factor (VEGF) were evaluated by immunostaining (IHC) analysis, ELISA assay, real-time quantitative polymerase chain reaction (RT-qPCR), and western blot analysis in vivo. Human dermal microvascular endothelial cells (HDMECs) and the shRNA interference technique were used to explore the effects of QSF on cell migration, PGT, PGE2, and angiogenesis factor VEGF in vitro. RESULTS: Applied QSF on the wound of db/db mice significantly accelerated wound closure. Reductions of PGT and elevations of PGE2 and increased angiogenesis factor VEGF levels were shown after QSF treatment in vivo and in vitro. Furthermore, QSF promoted HDMEC migration. Inhibition of the expression of PGT by shRNA reversed phenotypes of QSF treatment in vitro. CONCLUSION: Taken together, our findings reveal that QSF ameliorates diabetes-associated wound healing defects by abolishing the expression of PGT.
RESUMEN
BACKGROUND: Clinical comprehensive decision-making of diabetic ulcers includes curative effect evaluation and curative effect prediction. Nevertheless, there are few studies on the prediction of diabetic ulcers. METHODS: Set pair analysis (SPA) was used to assess the curative effect evaluation, and therapeutic effect was evaluated by connection degree (CD). The higher-order Markov chain-SPA curative effect prediction model was established to predict the future curative effect development. The predicted results with higher-order Markov chain-SPA and traditional first-order Markov-SPA model were compared with the actual results of the patients to verify the effectiveness of prediction. RESULTS: The connection degree of index levels I and II of 15 patients with diabetic ulcers after traditional Chinese medicine (TCM) treatment increased with time, while that of index levels IV and V decreased, indicating that the curative effect tends to improve. The higher-order Markov chain-SPA model was used to predict the curative effect. The results showed that the relative errors were fewer than the traditional first-order Markov-SPA model. CONCLUSIONS: The present study suggests that a method of SPA combined with higher-order Markov-SPA is relatively effective and can be applied to the clinical prediction of diabetic ulcers, which has higher accuracy than traditional first-order curative effect prediction model.
RESUMEN
OBJECTIVE: Gouty arthritis (GA) is a noninfectious inflammatory disease characterized by self-limited and severe pain. Huzhang Tongfeng granule is one of the most effective traditional Chinese medicines in the treatment of acute GA. However, its effects on the inflammatory factors in the process of acute gout inflammation remain unknown. In the present study, we aimed to evaluate the effect of Huzhang Tongfeng granule on the expressions of Cyr61 and related inflammatory factors in both experimental gout models in vivo and in vitro. METHODS: Huzhang Tongfeng granule was provided by the pharmaceutical preparation room of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine. The expressions of Cyr61, IL-1ß, TNF-α, and IL-6 in monosodium urate- (MSU-) induced rat models and fibroblast-like synoviocytes (FLSs) were determined by RT-PCR, Western blotting analysis, ELISA, immunohistochemistry, and hematoxylin and eosin staining. RESULTS: Huzhang Tongfeng granule could downregulate the expressions of IL-1ß, TNF-α, and IL-6 to some extent by inhibiting the expression of Cyr61. CONCLUSIONS: Collectively, our findings indicated that Cyr61 was highly expressed in rat models of gout. By inhibiting the expression of Cyr61, Huzhang Tongfeng granule could partially attenuate the inflammation induced by MSU crystal.
RESUMEN
Objective. To evaluate the effectiveness of external application of traditional Chinese medicine (EA-TCM) on venous ulcers. Methods. Seven databases were searched until April 2015 for randomized controlled trials (RCTs) of EA-TCM for venous ulcers. Risk of bias was assessed using Cochrane Handbook guidelines. Study outcomes were presented as risk ratios (RRs) for dichotomous data or mean differences (MDs) for continuous data. Results. Sixteen of 193 potentially relevant trials met the inclusion criteria; however, their methodological qualities were low. Comparison of the same intervention strategies revealed significant differences in total effectiveness rates between EA-TCM and conventional therapy groups (RR = 1.22, 95% confidence interval [CI] = 1.16-1.29, and P < 0.00001). Compared to conventional therapy, EA-TCM combined with conventional therapy had a superior total effectiveness rate (RR = 1.11, 95% CI = 1.04-1.19, and P = 0.003). There were no significant differences in recurrence rates during followup and final pain measurements between the experimental and those in the control groups (RR = 0.86, 95% CI = 0.31-2.39, and P = 0.85; MD -0.75, 95% CI = -2.15-0.65, and P = 0.29). Conclusion. The evidence that EA-TCM is an effective treatment for venous ulcers is encouraging, but not conclusive due to the low methodological quality of the RCTs. Therefore, more high-quality RCTs with larger sample sizes are required.
RESUMEN
OBJECTIVE: To investigate the levels of cytokines related to T-helper (Th) 17 cells in serum and signal transducers in the psoriatic lesions of patients with psoriasis vulgaris of blood-heat syndrome (BHS) and blood-stasis syndrome (BSS). METHODS: Sixty patients with psoriasis vulgaris were divided into the BHS and BSS groups according to the syndrome differentiation of Chinese medicine (CM). Ten healthy subjects were considered as the control group. Cytokine levels of interleukin (IL)-17, IL-23 and IL-6 in serum were determined by enzyme-linked immunosorbent assay. Expression levels of signal transducer and activator of transcription 3 (STAT3), p38-mitogen-activated protein kinase (MAPK) and STAT6 in the psoriatic lesions were determined using immunohistochemistry (IHC), Western blot, and real-time quantitative reverse transcription polymerase chain reaction, respectively. RESULTS: Production of IL-17, IL-23 and IL-6 in the BHS group and BSS group were significantly increased compared with those in the control group (P<0.05). Levels of IL-17 and IL-23 in the BHS group were higher than those in the BSS group (P<0.05). Compared with the control group, IHC positive expressions and protein expressions of STAT3 and p38-MAPK, and the STAT3 mRNA expressions in the BHS and BSS groups were significantly higher (P<0.05 or P<0.01). The protein expression of STAT3 in the BHS group was significantly higher than that in the BSS group (P<0.05). CONCLUSIONS: Cytokines in serum and signal transducers in the psoriatic lesions alter with various CM syndromes of psoriasis. The results provide scientific basis for the treatment based on syndrome differentiation of CM in treating psoriasis vulgaris.

OBJECTIVE: To study the effect of Shengji Huayu Recipe (SHR)on the expression of MMP-3 and TIMP-1 in the skin ulcer tissue of diabetic rats. METHODS: The skin ulcer model was established in diabetic mice. Different compatibility proportions of SHR [the ratio of Shengji Recipe (SJR) to Huayu Recipe (HYR) = 2:1, 1:1, and 1:2, respectively] were used to intervene. The expression of MMP-3 protein in the skin ulcer of diabetic rats was detected by Western blot method,and TIMP-1 protein was detected by immunohistochemical assay. RESULTS: At each time point, there was no statistical difference in the blood glucose level among groups (P > 0.05). But all of them increased significantly,when compared with those of the normal wound group (P < 0.01). As for the difference between after would area treatment and before would area treatment, better effect was obtained in the SHR No. 3 group and the normal ulcer group than in the diabetic ulcer model group (P < 0.05). Results of Western blot showed that the MMP-3 protein expression was higher in the SHR No. 2 group than in the SHR No.3 group (P < 0.05). Immunohistochemical results showed that TIMP-1 protein expression was lower in the SHR No. 2 group than in the SHR No. 3 group and the diabetic ulcer model group (P < 0.05). TIMP-1 protein expression was higherin the SHR No. 3 group than in the SHR No. 2 group (P < 0.01). CONCLUSION: Using SHR No.3 was conducive to the promotion of wound healing in early wound repair stage, and using SHR No. 2 might be conducive to inhibiting the formation of pathological scar.
