Objective: Enhancing innate immunity through interferons (IFNs) and IFN-stimulated genes (ISGs) offers a promising strategy for preventing herpes simplex virus type 1 (HSV-1) infection. Prunella vulgaris L., a medicinal herb, has demonstrated significant anti-HSV activity; in particular, its derived polysaccharide complex (PVE30) effectively inhibits viral replication. In this study, we investigate whether PVE30 exerts an anti-HSV-1 activity through activation of the innate immune response.

Methods: To determine the primary stage at which PVE30 exerts its effects during the HSV-1 life cycle, plaque reduction assays were conducted. Viral infection was further assessed by investigating the DNA copies, mRNA levels and protein expression of HSV-1 in infected cells using real-time polymerase chain reaction (RT-PCR) and Western blotting. The activation of the innate immune response was evaluated by detecting mRNA levels of ISGs, including MX dynamin-like GTPase 1 (Mx1), Mx2, 2'-5'-oligoadenylate synthetase 1 (OAS1), ISG15 and IFN regulatory factor 7 (IRF7) using RT-PCR, and levels of TANK-binding kinase 1 (TBK1) and IRF3 proteins using Western blotting. The translocation of phosphorylated IRF3 and stimulator of IFN genes (STING) was observed through fluorescence microscopy.

Results: PVE30 pre-treatment exerted protective effects against HSV-1 infection in human immortalized keratinocytes by enhancing the innate immune response. This was shown by increased transcriptional levels of IFN-β and antiviral ISGs, along with a significant reduction in HSV-1 DNA copies, mRNA expression and protein levels. Mechanistically, PVE30 promoted TBK1 phosphorylation, leading to nuclear translocation of IRF3 and subsequent IFN-β transcription; these effects were diminished by TBK1 inhibitor GSK8612. Additionally, STING was identified as a key mediator in PVE30-activated TBK1 signaling, as its inhibition induced by C-176 reduced PVE30's efficacy.

Conclusion: This study elucidated the molecular mechanisms underlying the protective effects of PVE30 against HSV-1 infection. PVE30 exerted its protective role by enhancing STING-TBK1-IRF3 pathway-mediated innate immune response.

Objective: This study investigated the effects of distinct electroacupuncture (EA) intensities in alleviating mechanical hypersensitivity by attenuating spinal dorsal horn (SDH) neuronal sensitization in inflammatory muscle pain.

Methods: Male Sprague-Dawley rats received an intra-muscular injection of complete Freund's adjuvant (CFA) in the left gastrocnemius muscle to induce inflammatory muscle pain. EA with distinct intensities activating Aβ-, Aδ- and C-fibers (EA_Aβ, EA_Aδ and EA_C) was applied after CFA injection. Pain behaviors were evaluated by weight-bearing asymmetry, the Randall-Selitto test, and the von Frey test. Spinal neuronal activities were observed by in vivo extracellular recordings with a microelectrode array. Neuronal sensitization was assessed through wind-up phenomenon of wide dynamic range (WDR) neurons and long-term potentiation (LTP) of spinal C-fiber-evoked field potential (CFEFP).

Results: Both EA_Aδ and EA_C significantly alleviated CFA-induced hyperalgesia. Moreover, EA_Aδ and EA_C interventions markedly reduced the activity of WDR neurons in response to stimulation. Importantly, the wind-up phenomenon of WDR neurons evoked by repetitive noxious stimuli was both immediately and sustainably reduced after EA intervention, with EA_C showing a more pronounced effect. Furthermore, EA_Aδ and EA_C increased the threshold of the spinal CFEFP, while EA_C intervention additionally significantly attenuated the occurrence of LTP.

Conclusion: Suppressing the SDH neuronal sensitization by activating Aδ- and C-fiber inputs may be the potential mechanism by which EA alleviates hyperalgesia in inflammatory muscle pain.

Background: Auriculotherapy is a simple, convenient, nonpharmacological option that has shown positive effects for insomnia patients, but its efficacy and safety remain unknown.

Objective: The aim of this study is to evaluate the efficacy and safety of auricular therapy for insomnia.

Design, setting, participants and intervention: An 18-week (2-week screening, 4-week treatment, and 12-week follow-up), recruiter- and assessor-blinded, randomized, sham-controlled trial was performed. Patients were recruited from outpatient settings at three clinical centers in China from 2 February 2023 to 26 January 2024. Participants had insomnia for more than 3 months and met the criteria classified in the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition). Patients were randomly assigned in a 1:1 ratio to receive auricular therapy (AT) or sham AT (SAT) for 4 consecutive weeks, twice a week, and once every 3 days.

Main outcome measures: Primary outcome was the response rate at week 4 after treatment, defined as the percentage of patients with at least a 50% reduction in Pittsburgh Sleep Quality Index (PSQI) from baseline. Secondary outcomes consisted of response rates at other time points, PSQI and 4 related scales, actigraphy-recorded sleep efficiency, sleep arousal frequency, and total sleep time.

Results: A total of 234 participants were screened, and 156 patients (122 female [78.2%]; mean [SD] age, 37.2 [13.5] years) were included in the intention-to-treat analysis, with 78 participants randomized to each group. A total of 117 participants (75%) were followed up for 3 months. The AT group had a higher response rate at week 4 than the SAT group (39.73% [29/73] vs 23.29% [17/73], P = 0.03), and the response rates for the AT and SAT groups at week 2 were 28.38% (21/74) and 13.33% (10/75), respectively (P = 0.02). The differences between the two groups in the PSQI at each time point (P < 0.05) and the Insomnia Severity Index at weeks 4 and 12 (both P = 0.03) were also statistically significant. The other partial outcomes also showed statistically significant differences. Adverse events occurred in 2 cases in the AT group (2.60%).

Conclusion: Four-week AT treatment was an effective and safe alternative therapy for insomnia, although the difference with the SAT treatment did not reach the minimal clinically important difference. Adverse events were mild or transient.

Objective: Xinyang Tablet (XYAT) and Xinyin Tablet (XYIT) have been used to treat chronic heart failure (CHF) for 20 years. This study investigated their pharmacodynamic material basis and underlying mechanisms of action.

Methods: Ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UPLC-HRMS) was used to identify the components of XYAT and XYIT, and to profile their metabolites in plasma and urine samples from both rats and human volunteers. Furthermore, the prototype compounds and their pharmacokinetics were evaluated using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Network pharmacology predicted potential targets and pathways, which were subsequently validated through flow cytometry and Western blot. The efficacy of XYAT, XYIT and their active components was evaluated in oxidative stress and cardiotoxicity models.

Results: A total of 162 and 130 compounds were detected in XYAT and XYIT, respectively; among these, 148 from XYAT and 119 from XYIT were structurally identified. A validated HPLC-MS/MS method quantified 20 key exposure components, five of which showed high systemic exposure and underwent pharmacokinetic analysis. Pharmacokinetic results indicated that the systemic exposure of most compounds was higher for XYAT than for XYIT. Using network pharmacology, seven candidate active compounds were identified, along with their predicted therapeutic targets and associated signaling pathways. Flow cytometry and Western blot confirmed that XYAT, XYIT, and their bioactive components alleviate CHF by modulating calcium signaling and phosphoinositide 3-kinase/protein kinase B signaling. Pharmacodynamic assays demonstrated that XYAT provides protection against hydrogen peroxide-induced injury, while XYIT mitigates doxorubicin-induced cytotoxicity. Further validation confirmed that 20(S)-ginsenoside Rg2 and 20(R)-ginsenoside Rh1 effectively reduced the H₂O₂-induced oxidative stress, while 20(S)-ginsenoside Rg2 and calycosin-7-O-β-D-glucoside significantly protected against doxorubicin-induced cytotoxicity.

Conclusion: These findings provide mechanistic insights into the pharmacodynamic material basis and anti-CHF mechanisms of XYAT and XYIT. The integrated strategy established herein offers robust evidence that the superior systemic exposure of key components underpins the rationale for XYAT's formulation and warrants its continued development in modern cardiology.

Objective: Alzheimer's disease (AD) and Parkinson's disease (PD) are major age-related neurodegenerative disorders that currently lack effective disease-modifying therapies. This study investigated the neuroprotective potential and underlying mechanisms of natural products derived from medicine-food homology (MFH) plants, with a focus on autophagy modulation in AD and PD models.

Methods: Twenty MFH plant extracts were screened using the Caenorhabditis elegans amyloid-β peptide (Aβ) proteotoxicity model CL4176. Mung bean coat extract (MBCE) was identified as a promising candidate and subsequently evaluated in transgenic C. elegans models of AD and PD to assess its effects on pathological protein aggregation, oxidative stress, and behavioral impairments. Autophagy activation was assessed using fluorescence microscopy and lysosomal activity assays. MBCE's effects on protein aggregation and apoptosis were further validated in rat pheochromocytoma (PC-12) cells. Mechanistic insights were obtained through pharmacological inhibition of autophagy and AMP-activated protein kinase (AMPK) signaling, as well as AMPK knockdown. A bioactivity-guided analysis was performed to identify the major active constituents of MBCE.

Results: MBCE significantly alleviated Aβ- and microtubule-associated protein tau (Tau)-induced neurotoxicity in C. elegans by reducing protein aggregation, oxidative stress, and locomotor deficits. It also suppressed α-synuclein accumulation and preserved dopaminergic neuron integrity in PD models. MBCE enhanced stress resistance and activated autophagy, as evidenced by increased autophagosome formation, decreased sequestosome-1 (p62/SQSTM1) levels, and elevated lysosomal activity. RNA interference knockdown assays confirmed that MBCE's neuroprotective effects were dependent on autophagy activation. In PC-12 cells, MBCE similarly induced AMPK-mediated autophagy, reduced the accumulation of disease-related proteins, and mitigated cytotoxicity. Notably, genetic knockdown or pharmacological inhibition of AMPK or autophagy abolished these effects. Vitexin and isovitexin, the main constituents of MBCE, were identified as key contributors to its autophagy-inducing and neuroprotective activities.

Conclusion: MBCE mitigates neurodegenerative pathology in AD and PD models by promoting AMPK-dependent autophagy and reducing toxic protein aggregation. These findings support the potential of MBCE as a functional food-based therapeutic strategy for neurodegenerative diseases.

Objective: Gastric ulcers are a global health issue, often occurring in the stomach or duodenum and causing tissue necrosis. Talinum paniculatum (Jacq.) Gaertn (Erva-gorda) is used in traditional medicine for treating gastric ulcers. This study aimed to assess the gastroprotective effects of the ethanol-soluble fraction from T. paniculatum leaves (ESTP) in rodents.

Methods: The gastroprotective potential of ESTP was evaluated at 30, 100, and 300 mg/kg taken orally, or 30 mg/kg intraperitoneally against gastric lesions induced by a 60% ethanol solution containing 0.3 mol/L hydrochloric acid, in mice. Histological sections were examined after hematoxylin-eosin staining and their mucin content was determined using the periodic acid-Schiff method. Oxidative stress markers, including levels of reduced glutathione and lipid hydroperoxide, as well as inflammatory parameters such as myeloperoxidase activity and nitrite levels, were analyzed. Mechanistic studies involved pretreating the mice with N-ethylmaleimide (NEM), N-nitro-l-arginine methyl ester (L-NAME), and indomethacin.

Results: ESTP at 300 mg/kg orally and 30 mg/kg intraperitoneally significantly reduced ethanol/HCl-induced gastric injury. It decreased lipid hydroperoxide levels but did not increase levels of reduced glutathione. Myeloperoxidase activity and nitrite levels were reduced. However, ESTP did not restore mucin levels. Pretreatment with indomethacin nullified the protective effects of ESTP while NEM and L-NAME did not.

Conclusion: ESTP demonstrated a remarkable gastroprotective effect, as indicated by reductions in inflammatory and oxidative mediators. The observed decline in mucin activity, coupled with the absence of an effect following indomethacin pretreatment, implies a potential inhibition of the cyclooxygenase activity by the extract. These findings collectively support the traditional use of the species for gastrointestinal protection and highlight its potential as a therapeutic agent for managing gastric ulcers.
