Breaking the scar barrier: The anti-fibrotic and hemodynamic benefits of total salvianolic acid in hypertrophic scars

Hypertrophic scars (HS) affect up to 70 % of individuals following deep dermal injuries, burns, or surgical procedures, leading to significant functional impairments and psychological distress. Despite their high prevalence, effective therapeutic options remain limited, and the underlying pathophysiology is not fully elucidated. This study integrates network pharmacology, molecular docking, and in vivo experimentation to investigate the therapeutic potential of total salvianolic acid (TSA) from Salvia miltiorrhiza in HS treatment. A systematic pharmacology approach identified 186 target proteins, highlighting TGF-β1, Smad3, IL-2, and IL-4 as key modulators of fibrosis and inflammation. Molecular docking confirmed high-affinity interactions between TSA's active components and these targets. TSA significantly reduced scar elevation, fibrosis, and collagen deposition in a rabbit ear hypertrophic scar model, restoring tissue architecture and improving hemorheological parameters. Histological and immunohistochemical analyses confirmed TSA's ability to suppress TGF-β/Smad signaling, downregulate inflammatory cytokines and normalize collagen dynamics. These findings provide compelling evidence that TSA is a multi-targeted, pharmacologically active compound with promising anti-fibrotic and microcirculatory benefits, paving the way for novel therapeutic strategies in HS management. This study establishes a scientific foundation for TSA-based interventions, with potential clinical implications in regenerative medicine and scar therapy.

Strategies for Reducing the Homogenization Phenomenon in the Screening of Key Components in Network Pharmacology Based on the Detectability of Components

BACKGROUND

The ingredients of traditional Chinese medicine (TCM) are complex and diverse and are often identified using the TCM systems pharmacology (TCMSP) database. However, the ingredients in this database exhibit significant homogeneity, which limits the comprehensive understanding of TCM's ingredient diversity and biological activity. Consequently, liquid chromatography-mass spectrometry (LC-MS) has become a key tool for the precise identification of TCM components.

METHODS

In this study, the LC-MS was used to identify the components of a TCM herb. The identified components were then compared with the component data in the TCMSP database. A network pharmacological prediction of the components was subsequently performed.

RESULTS

An analysis of the four herb formula prescriptions (Ganmai Dazao decoction, Bazhen granule, Shaoyao Gancao decoction, and Zixue san) was conducted, revealing significant discrepancies between the LC-MS identification results and the components in the TCMSP database. The database components were found to be highly homogeneous.

CONCLUSION

This study underscores the pivotal function of LC-MS in the analysis of components of TCM, particularly in addressing issues of database homogeneity. The employment of LC-MS technology enhances the precision of ingredient identification and streamlines the identification of potential pharmacodynamic ingredients, thereby propelling TCM toward a more contemporary standing.

A Multi-Level Study on the Anti-Lung Cancer Mechanism of Peiminine, a Key Component of Fritillaria ussuriensis Maxim.: Integrating Quality Analysis, Network Pharmacology, Bioinformatics Analysis, and Experimental Validation

Globally, lung cancer is the primary cause of deaths associated with cancer; however, current therapies are costly and toxic, highlighting the need for novel treatments. Peiminine (Verticinone), a key bioactive compound derived from Fritillaria ussuriensis Maxim., has demonstrated diverse biological activities. However, the precise pharmacological mechanisms underlying its anti-lung cancer effects remain unclear. The objective of this study was to quantify the content of peiminine in Fritillaria ussuriensis Maxim. from different geographical regions using UHPLC-MS/MS and to elucidate the anti-lung cancer mechanisms of peiminine through network pharmacology, bioinformatics, and in vitro experiments. The content of peiminine in Fritillaria ussuriensis Maxim. from various regions was determined using UHPLC-MS/MS. Potential target genes associated with peiminine and lung cancer were systematically screened from multiple databases. To identify core genes, we set up a PPI (protein-protein interaction) network, followed by in-depth analyses of their corresponding target proteins. Survival analysis, molecular docking, and dynamics simulations were used to explore potential anti-cancer mechanisms. In vitro experiments on human H1299 NSCLC cells assessed peiminine's anti-tumor activity and measured key gene transcription levels. UHPLC-MS/MS analysis revealed that Fritillaria ussuriensis Maxim. from Mudanjiang (Heilongjiang Province) exhibited the highest peiminine content. Network pharmacological analysis identified PIK3CG, SRC, JAK3, AKT2, and PRKCA as key potential targets of peiminine in lung cancer treatment. Molecular docking results demonstrated strong binding affinities between peiminine and PIK3CG, SRC, and JAK3; these results were further confirmed using molecular dynamics simulations. Survival analysis indicated that a high AKT2 and PRKCA expression correlated with bad prognosis in lung cancer patients. In vitro, peiminine inhibited H1299 cell viability and regulated genes involved in the PI3K-Akt pathway (PI3K, AKT, and PTEN) and apoptosis (Bcl-2, Bax), suggesting that it may induce its effects via PI3K-Akt pathway inhibition. Peiminine from Fritillaria ussuriensis Maxim. exhibits significant anti-lung cancer potential by targeting key genes such as PIK3CG, SRC, and JAK3, as well as by modulating the PI3K-Akt signaling pathway and apoptosis-related genes. These results lay a foundation for further investigations into peiminine as a potentially effective therapeutic option for treating lung cancer. Additionally, the identified targets (PIK3CG, SRC, JAK3, AKT2, and PRKCA) may function as possible biomarkers for predicting lung cancer prognosis and guiding personalized therapy.

Current developments of pharmacotherapy targeting heme oxygenase 1 in cancer (Review)

Malignant tumors are non-communicable diseases that impact human health and quality of life. Identifying and targeting the underlying genetic drivers is a challenge. Heme oxygenase-1 (HO-1), a stress-inducible enzyme also known as heat shock protein 32, plays a crucial role in maintaining cellular homeostasis. It mitigates oxidative stress-induced damage and exhibits anti-apoptotic properties. HO-1 is expressed in a wide range of malignancies and is associated with tumor growth. However, the precise role of HO-1 in tumor development remains controversial. Drugs, both naturally occurring and chemically synthesized, can inhibit tumor growth by modulating HO-1 expression in cancer cells. The present review aimed to discuss biological functions of HO-1 pharmacological therapies targeting HO-1.

Mechanistic insights into the role of traditional Chinese medicine in treating gastric cancer

Gastric cancer remains a leading cause of cancer-related mortality worldwide, with advanced stages presenting significant challenges due to metastasis and drug resistance. Traditional Chinese Medicine (TCM) offers a promising complementary approach characterized by holistic treatment principles and minimal side effects. This review comprehensively explores the multifaceted mechanisms by which TCM addresses gastric cancer. Specifically, we detail how TCM inhibits aerobic glycolysis by downregulating key glycolytic enzymes and metabolic pathways, thereby reducing the energy supply essential for cancer cell proliferation. We examine how TCM suppresses angiogenesis by targeting the vascular endothelial growth factor (VEGF) and cyclooxygenase-2 (COX-2) pathways, effectively starving tumors of nutrients and oxygen required for growth and metastasis. Furthermore, TCM modulates the immune microenvironment by enhancing the activity of effector immune cells such as CD4+ and CD8+ T cells and natural killer (NK) cells while reducing immunosuppressive cells like regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs). These actions collectively contribute to slowing tumor progression, inhibiting metastasis, and enhancing the body's antitumor response. The insights presented underscore the significant potential of TCM as an integral component of comprehensive gastric cancer treatment strategies, highlighting avenues for future research and clinical application to improve patient outcomes.

Influencing factors, evolution, and strategies for improving the quality of traditional Chinese medicine patents: an empirical study based on patent invalidation cases

This study analyzes 134 invalidated traditional Chinese medicine (TCM) patents from 1984 to 2021 to explore common weaknesses and track quality progression. The findings highlight that TCM patents applied for between 2001 and 2005 face higher invalidation rates, with disputes often arising 4-7 years post-application. Disputes are concentrated in patents related to cardiovascular and cerebrovascular diseases, exacerbated by widespread geographical distribution and technology saturation. Combination patents are more prone to invalidation than single-component ones, and patents using preparation methods to describe products carry hidden risks. Additionally, citing more references positively impacts patent stability. Despite progress, TCM patents still encounter significant challenges in quality and consistency.

Topical and transdermal botanical formulations of the Chinese pharmacopoeia-A review

In pharmaceutics, ingredients are classified as active ingredients and excipients. In topical/transdermal phytomedicines, an ingredient may serve both functions. Published information on these dual-purpose ingredients and their pharmacological relevance is limited. An intriguing scenario arises in traditional Chinese medicine (TCM) formulations, where active ingredients and excipients are undifferentiated. This study analyzes ingredients in TCM topical/transdermal formulations, aiming at harmonization of understanding of TCMs. The most commonly recorded ingredients from such formulations in the Chinese pharmacopoeia 2020 (ChP 2020) are reviewed, aiming at developing innovative topical/transdermal phytomedicines. Current editions of Chinese historical documents were reviewed to explore the principles underlying the use of these ingredients. TCM formulations containing botanical drugs for topical/transdermal application were selected from the ChP 2020. The use of botanical materials in TCM formulations is guided by the "Jun-Chen-Zuo-Shi" principle rooted in Yin-Yang and the five elements' theories. In the ChP 2020, 155 botanical drugs, along with 40 excipients (from the "procedure" section, focusing on processing and technical parameters), were identified from 34 botanical formulations intended for topical/transdermal application. Pungent and aromatic botanical materials were the most frequently recorded. Adhesive plasters were the most commonly recorded TCM dosage form, employing specific matrix blends. This new perspective of study reveals the prevalence of pungent and aromatic botanical materials, the common use of adhesive plasters, multifunctional properties of botanical oils, and formulation adaptability in TCM topical/transdermal products. These insights should inform novel formulation designs for both pharmaceutical and phytopharmacological research.

Qingxin Kaiqiao Fang decreases Tau hyperphosphorylation in Alzheimer's disease via the PI3K/Akt/GSK3β pathway in vitro and in vivo

ETHNOPHARMACOLOGICAL RELEVANCE

Alzheimer's disease (AD) belongs to the category of "senile dementia" in traditional Chinese medicine. AD is associated with brain emptiness or collaterals blocked by phlegm-heat. "Fumanjian" from Jingyue Quanshu treats dementia by promoting qi circulation, alleviating depression, eliminating turbidity, cultivating positivity, and dispelling evil spirits. Qingxin Kaiqiao Fang (QKF), derived from Fumanjian, is effective in treating AD owing to previously mentioned clinical effects. Elucidating the mechanism(s) of action of QKF on AD associated with phlegm-heat may be beneficial for therapeutic management; however, further research is needed.

AIM OF THE STUDY

This study aimed to determine the role of the PI3K/Akt pathway in AD, especially the specific effector protein involved, and explore the efficacy of QKF in treating AD by modulating the PI3K/Akt signal.

MATERIALS AND METHODS

High-performance liquid chromatography-Q-orbitrap-mass spectrometry was used to analyze the chemical components of QKF. Subsequently, APP/PS1 double-transgenic mice were used for behavioral tests, and hematoxylin-eosin and Nissl staining were used to assess the neuroprotective and cognitive effects of QKF. Cerebrospinal fluid pharmacology was used in in vitro validation, and Aβ25-35 was used to induce PC12 cells to establish the AD cell model. Various methods, including immunohistochemistry, Western blotting, quantitative real-time polymerase chain reaction, morphological assay, cell counting kit-8(CCK-8) assay, and terminal deoxynucleotide transferase (TdT)-mediated dUTP nick-end labeling (TUNEL)staining, were used to evaluate the effect of QKF on Tau hyperphosphorylation and anti-apoptosis. These methods also assessed the influence of QKF on the PI3K/Akt/GSK3β pathway involving the mRNA and protein expressions. Finally, the inhibitor - LY294002 was used for reverse validation.

RESULTS

We identified 295 chemical components in the water extract of QKF.QKF improved spatial cognition and learning memory in APP/PS1 mice, protected PC12 cell morphology, improved cell survival, reduced Aβ25-35-induced apoptosis, and inhibited the hyperphosphorylation of Tau protein via the PI3k/Akt/GSK3β signaling pathway. Furthermore, this protective effect of QKF was reduced by LY294002 in vitro.

CONCLUSIONS

QKF can improve spatial cognition, learning, and memory abilities in APP/PS1 mice and protect PC12 cells. Decreasing the Tau hyperphosphorylation in AD exhibits curative efficacy on AD via the PI3K/Akt/GSK3β pathway in vitro and in vivo.

The effect and mechanism of Huangqin-Baishao herb pair in the treatment of dextran sulfate sodium-induced ulcerative colitis

Background

The haungqing (Scutellariae Radix) and baishao (Paeoniae Radix Alba) herb pair (HBHP) is a common prescribed herbal formula or is added to other traditional Chinese medicine (TCM) prescriptions to treat ulcerative colitis (UC). However, the underlying mechanism is unclear.

Purpose

Elucidate the efficacy and potential mechanism of HBHP against UC.

Methods

First, The UC model of mice induced by dextran sulfate sodium (DSS) was established. The mice were randomly divided into Control group, DSS group, SASP group (390 mg/kg), and HPHP group (1.95 g/kg), with 8 mice per group. Drugs were administrated via oral gavage for 7 days. Then, Disease activity index (DAI), length of the colon, histopathology, and changes in inflammatory cytokines in colonic tissues were analyzed to assess the effect of HBHP on UC. Besides, Network pharmacology was applied to identify the active compounds, core targets of HBHP in the treatment of UC, and the corresponding signaling pathways to explore the underlying mechanisms. Finally, Western blot (WB), immunohistochemistry (IHC) and molecular docking were performed to validate the results.

Results

HBHP significantly reduced DAI score and decreased colon length shortening in DSS-induced UC mice. The administration of HBHP was able to effectively alleviated mucosal ulceration and epithelial destruction. In addition, HBHP treatment obviously - reduced the expressions of TNF-α, IL-6, and IL-1β in colon tissues (p < 0.05 or p < 0.01). 35 bioactive compounds and 290 HBHP targets related to UC were obtained. Among them 3 key active compounds (baicalein, panicolin, and norwogonin) with higher degree values in the drug-compound-target network and 21 hub genes (STAT3, JAK2, SRC, AKT1, PIK3CA, and VEGFA, etc.) were identified. KEGG enrichment analysis suggested that HBHP's mechanisms mainly involve the JAK-STAT pathway. Abnormal activation of JAK/STAT signaling is believed to be involved in the pathogeneses of UC. Notably, WB and IHC showed that HBHP significantly down-regulated the protein expression levels of p-JAK2 (p < 0.05) and p-STAT3 (p < 0.05 or p < 0.01). JAK2 and STAT3 might be core targets for the action of HBHP; this possibility was also supported by molecular docking.

Conclusions

HBHP could alleviate DSS-induced UC, reduce tissue inflammation, and its mechanism might primarily be achieved by inhibiting JAK2/STAT3 signaling pathway. Meanwhile, our work revealed that network pharmacology combined with experimental verification is a cogent means of studying the mechanism of TCM.
