As a serious complication of diabetes, nonhealing skin ulcer leads to high mortality and disability in diabetic patients. However, limited therapy is available in managing diabetic wounds. In this study, RNA-seq technology was used to systematically investigate the effect of Huangbai (HB) liniment, a traditional Chinese medicine, on the streptozotocin- (STZ-) induced diabetic wound. HB liniment significantly accelerated the wound closure and enhanced the generation of extracellular matrix in diabetic rats, and oxidative stress was identified to play a vital role in HB-mediated wound healing. Importantly, HB liniment activated nuclear factor erythroid-derived 2-like 2 (Nrf2) and its downstream antioxidant genes (e.g., genes involved in glutathione system, thioredoxin system, and GAPDH generation as well as other antioxidant genes), which inhibited oxidative damage and apoptosis. By associating drug targets of HB liniment with Nrf2 and its downstream genes, 54 components in HB liniment were screened out, and the majority was from Cortex Phellodendri and Forsythia suspensa. Additionally, HB liniment enhanced TGF-1 and reduced MMP9 level, accelerating wound healing in diabetes. The experiment showed HB facilitated cell proliferation and inhibited oxidative damage in high glucose-induced HaCaT cells. Our findings provided the experimental evidence for the treatment of diabetic wound with HB, clarified the potential mechanism of HB, and improved our understanding of diabetic wound healing.

Diabetic ulcer is a challenging complication of diabetes mellitus but current treatments cannot achieve satisfactory results. In this study, the effect of Huangbai liniment (HB) and berberine on the wound healing in high fat diet/streptozotocin injection induced diabetic rats was investigated by RNA-seq technology. HB topical treatment promoted wound healing in the diabetic patients and diabetic rats, and it affected multiple processes, of which IL-17 signalling pathway was of importance. Inhibiting IL-17a by its inhibitor or antibody remarkably facilitated wound healing and HB significantly repressed the high IL-17 expression and its downstream targets, including Cxcl1, Ccl2, Mmp3, Mmp9, G-CSF, IL1B and IL6, in diabetic wounds, promoted T-AOC, SOD activity and GSH levels; decreased the levels of nitrotyrosine and 8-OHdG; enhanced angiogenesis-related CD31, PDGF-BB and ANG1 expression; inhibited cleaved caspase-3 levels and promoted TIMP1 and TGFB1. Moreover, berberine (a major component in HB) repressed the IL-17 signalling pathway, and promoted wound healing in diabetes mellitus. This study highlights the strategy of targeting IL-17a in diabetic wounds, deepens the understanding of wound healing in diabetes mellitus in a dynamic way and reveals the characteristics of HB and berberine in promoting wound healing of type 2 diabetes mellitus.

Atopic dermatitis (AD), also known as atopic eczema, is one of the most common skin diseases and is characterized by allergic skin inflammation, redness, and itchiness and is associated with a hyperactivated type 2 immune response. The leading causes of AD include an imbalance in the immune system, genetic predisposition, or environmental factors, making the development of effective pharmacotherapies complex. Steroids are widely used to treat AD; however, they provide limited efficacy in the long term and can lead to adverse effects. Thus, novel treatments that offer durable efficacy and fewer side effects are urgently needed. Here, we investigated the therapeutic potential of Huangbai Liniment (HB), a traditional Chinese medicine, using an experimental AD mouse model, following our clinical observations of AD patients. In both AD patient and the mouse disease model, HB significantly improved the disease condition. Specifically, patients who received HB treatment on local skin lesions (3-4 times/day) showed improved resolution of inflammation. Using the 1-Chloro-2,4-dinitrobenzene (DNCB)-induced AD model in BALB/c mice, we observed that HB profoundly alleviated severe skin inflammation and relieved the itching. The dermatopathological results showed markedly reversed skin inflammation with decreased epidermal thickness and overall cellularity. Correspondingly, HB treatment largely decreased the mRNA expression of proinflammatory cytokines, including IL-1β, TNF-α, IL-17, IL-4, and IL-13, associated with declined gene expression of IL-33, ST2, and GATA3, which are connected to the type 2 immune response. In addition, HB restored immune tolerance by promoting regulatory T (T) cells and inhibiting the generation of T1, T2, and T17 cells and in the DNCB-induced AD mouse model. For the first time, we demonstrate that HB markedly mitigates skin inflammation in AD patients and the DNCB-induced AD mouse model by reinvigorating the T cell immune balance, shedding light on the future development and application of novel HB-based therapeutics for AD.

Review
The most effective and safe treatment site for pain is in the skin. This chapter discusses the reasons to treat pain in the skin. Pain is sensed in the skin through transient receptor potential cation channels and other receptors. These receptors have endogenous agonists (yang) and antagonists (yin) that help the body control pain. Acupuncture works through modulation of these receptor activities (qi) in the skin; as do moxibustion and liniments. The treatment of pain in the skin has the potential to save many lives and improve pain therapy in most patients.

OBJECTIVE
To explore the effects of Huhuang Burn Liniment on wound healing and levels of interleukin-10 (IL-10) and matrix metalloproteinase-9 (MMP-9) in patients with mixed hemorrhoids.
METHODS
The clinical data of 113 patients with mixed hemorrhoids admitted to Chongqing Sanxia Central Hospital were retrospectively collected. All patients underwent Milligan-Morgan hemorrhoidectomy, and were divided into two groups according to different postoperative treatments. Group A was treated with 1/5000 potassium permanganate sitz bath after surgery, while group B was treated with Huhuang Burn Liniment. The treatment efficacy, wound healing time, level of pain, exudation, edema, granulation scores, anal function index, levels of IL-10 and MMP-9, quality of life scores, and complications were compared between the two groups.
RESULTS
The effective rate of group B (94.74%) was higher than that of group A (60.71%) ( < 0.05). Group B had shorter length of anorectal hyperbaric zone, higher anal canal resting pressure, anal canal diastolic pressure, and anal canal systolic maximum pressure ( < 0.05), lower scores of trauma pain, edema, exudation, and granulation ( < 0.05), higher IL-10 levels, and lower MMP-9 levels ( < 0.05). The complication rate of group B (8.77%) was lower than that in group A (23.21%) ( < 0.05). After treatment, group B had shorter wound healing time and higher quality of life score than group A ( < 0.05).
CONCLUSION
The application of Huhuang Burn Liniment in patients with mixed hemorrhoids after surgery could promote wound healing and anal function, reduce trauma pain, exudation and edema, and improve quality of life.

OBJECTIVE
To analyze the effect of polydatin (PD) from Huhuang Shaoshang Liniment on oxidative damage and inflammatory response in rats with cerebral ischemia-reperfusion (CI/R), and the effect of PD on NF-E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1)/NAD(P)H quinone oxidoreductase 1 (NQO1) pathway.
METHODS
The rat model of focal CI/R was established using suture-occlusion method and treated with intraperitoneal injection of PD (25 mg/kg and 50 mg/kg). High performance liquid chromatography (HPLC) was used to determine the PD content in three batches of Huhuang Shaoshang Liniment. The neurological function scores of each group were observed at 24 h, 48 h, and 72 h postoperatively. The hematoxylin and eosin (HE) staining was conducted to observe the morphological structure of brain tissue, the triphenyltetrazolium chloride (TTC) staining was used to determine the size of cerebral infarction, and the neuronal apoptotic index was calculated using image analysis system under the optical microscope. The expressions of the Nrf2/HO-1/NQO1 pathway and neuronal apoptosis-related proteins in brain tissue were measured using Western blot.
RESULTS
The PD content in three batches of Huhuang Shaoshang Liniment was detected by HPLC, and the average result showed that the product contained 0.73 mg PD per 1 mL. The PD 50 mg/kg group and 25 mg/kg group showed lower neurological function scores at 24 h, 48 h, and 72 h postoperatively, lower percentage of cerebral infarction area on the ischemic side and apoptotic index, lower interleukin (IL)-1β, IL-6, malondialdehyde (MDA), and lactate dehydrogenase (LDH) levels, and lower Bax protein expression (P < 0.05), and showed higher IL-4, IL-10, superoxide dismutase (SOD), glutathione peroxidase (GPx), Nrf2, HO-1, NQO1, and c-Myc protein expression than the CI/R group (P < 0.05).
CONCLUSION
PD from Huhuang Shaoshang Liniment can alleviate neurological damage, improve neuronal morphology and structure, reduce cerebral infarction area, alleviate oxidative damage and inflammatory response, and inhibit neuronal cell apoptosis in CI/R model rats.

Review
Plantago major has been used widely since ancient times, to manage a wide range of diseases including constipation, coughs and wounds. The aim of this study is to review the traditional application, botanical characterization, pharmacological activities, phytochemistry effects and toxicity of Plantago major. In this review study, medicinal properties of Plantago major are collected from credible pharmacopeias, textbooks of traditional Persian medicine (TPM) belonging to the 10-18th century AD, such as "The Canon of Medicine", "Makhzan-Al- Advia" and so on. Moreover, electronic databases including Scopus, Medline and Web of science were explored for this purpose. Plantago major has been prescribed in various forms such as roasted seeds, decoction, syrup, liniment, gargle, rectal enema, vaginal suppository, eye and nasal drop for each illness by TPM scholars. Some of its traditional properties including wound healing, antipyretic, antitussive, anti-infective, anti-hemorrhagic, anti-inflammatory, diuretic, laxative, astringent and hemostatic have been confirmed in recent researches. Phytochemical investigations showed that Plantago major contains volatile compounds, triterpenoids, phenolic acids and flavonoids. Modern pharmacological studies have proven some of the traditional applications of Plantago major. Nevertheless, more investigations are required on this plant, because it has the potential to be used to produce various natural medications.

Compound methyl salicylate liniment (Ammeltz) is composed of various components, such as methyl salicylate, menthol, camphor, chlorpheniramine maleate, and thymol. It was approved for listing in China in 2011. The purpose of this phase Ⅳ clinical trial was to evaluate the safety and efficacy of Ammeltz in a real-life environment in China. Adverse events and adverse drug reactions were used to assess the safety of the monitored drugs. Visual analog scale (VAS) scores were evaluated to assess the severity of pain and the pain relief rate was used to evaluate the efficacy of the study drug. Of 3,600 subjects enrolled, 3,515 (97.64%) subjects completed the study and 85 (2.36%) terminated the study prematurely. A total of 277 adverse events occurred in 258 subjects (7.28%). The most common adverse events included upper respiratory infections (130 cases, 3.67%), local pruritus (17 cases, 0.48%), and diarrhea (12 cases, 0.34%). A total of 50 (1.41%) subjects experienced 58 adverse drug reactions. The most common adverse drug reactions included local pruritus (17 cases, 0.48%), a burning sensation at the application site (10 cases, 0.28%), and irritation at the application site (local) (7 cases, 0.2%). No adverse reactions were identified as new adverse drug reactions. The majority of adverse drug reactions were mild (48 cases, 1.36%), and no severe adverse drug reactions occurred. The subjects experienced significant pain relief after using Ammeltz (mean VAS scores: 5.34 . 2.79; Day 7 ± 1 . Baseline; < 0.0001). The pain relief rate was 47.11% ± 23.13%, and in 2,769 cases (78.31%) the drug was effective in pain relief. After excluding subjects who used drugs that could affect the efficacy of the study drug, the subgroups of subjects experienced significant pain relief after using Ammeltz (mean VAS scores: 5.31 vs 2.77; Day 7 ± 1 vs Baseline; < 0.0001). The pain relief rate was 47.34% ± 23.00%, and 2,612 subjects (78.75%) experienced effective pain relief. In conclusion, Ammeltz is safe and effective in real-life use. It can significantly relieve soft tissue pain caused by shoulder and neck pain, back pain, or muscle pain. No new adverse drug reactions were found in our multicenter real-world study. https://clinicaltrials.gov/ct2/show/NCT05489939?cond=Safety+and+efficacy+of+compound+methyl+salicylate+liniment+for+topical+pain%3A+A+multicenter+real-world+study+in+China&draw=2&rank=1, identifier NCT05489939.

The feasibility of bispectral imaging photoplethysmography (iPPG) system for clinical assessment of cutaneous microcirculation at two different depths is proposed. The iPPG system has been developed and evaluated for in vivo conditions during various tests: (1) topical application of vasodilatory liniment on the skin, (2) skin local heating, (3) arterial occlusion, and (4) regional anesthesia. The device has been validated by the measurements of a laser Doppler imager (LDI) as a reference. The hardware comprises four bispectral light sources (530 and 810 nm) for uniform illumination of skin, video camera, and the control unit for triggering of the system. The PPG signals were calculated and the changes of perfusion index (PI) were obtained during the tests. The results showed convincing correlations for PI obtained by iPPG530 nm and LDI at (1) topical liniment (r = 0.98) and (2) heating (r = 0.98) tests. The topical liniment and local heating tests revealed good selectivity of the system for superficial microcirculation monitoring. It is confirmed that the iPPG system could be used for assessment of cutaneous perfusion at two different depths, morphologically and functionally different vascular networks, and thus utilized in clinics as a cost-effective alternative to the LDI.
