RESUMEN

Eucommia ulmoides (EU) is a precious tree species native to China originating during the ice age. This species has important economic value and comprehensive development potential, particularly in medicinal applications. The medicinal parts of EU are its bark (Eucommiae cortex) and leaves (Eucommiae folium) which have been successively used as a traditional Chinese medicine to treat diseases since the first century BC. During the last 2 decades, as natural polysaccharides have become of increasing interest in pharmacology, biomedicine, cosmetic and food applications, more and more scholars have begun to study polysaccharides derived from EU as well. EU polysaccharides have been found to have a variety of biological functions both in vivo and in vitro, including immunomodulatory, antioxidant, anti-inflammatory, anticomplementary, antifatigue, and hepatoprotective activities. This review aims to summarize these recent advances in extraction, purification, structural characteristics, pharmacological activities and applications in different fields of EU bark and leaf polysaccharides. It was found that both Eucommiae folium polysaccharides and Eucommiae cortex polysaccharides were suitable for medicinal use. Eucommiae folium may potentially be used to substitute for Eucommiae cortex in terms of immunomodulation and antioxidant activities. This study serves as a valuable reference for improving the comprehensive utilization of EU polysaccharides and further promoting the application of EU polysaccharides.

RESUMEN

INTRODUCTION: Spinal cord injury (SCI) may bring lifelong consequences for affected patients and a high financial burden to the health care system. SOURCE OF DATA: Published peer-reviewed scientific articles identified from EMBASE, Google Scholar, PubMed and Scopus. AREAS OF AGREEMENT: Surgery and blood pressure management are the main targets in acute SCI to avoid secondary damage. AREAS OF CONTROVERSY: The management of secondary chronic SCI is challenging, with unpredictable outcomes. GROWING POINTS: Given the lack of consensus on pharmacological therapy for acute and secondary chronic SCI, the present study analyses the currently available drugs and treatment options to manage secondary chronic SCI. AREAS TIMELY FOR DEVELOPING RESEARCH: Different approaches exist for the pharmacological management of secondary chronic SCI. One of the most investigated drugs, 4-aminopyridine, improves central motor conduction and shows improvement in neurological signs. Positive results in different areas have been observed in patients receiving the anti-spastic drugs tizanidine and baclofen or Granulocyte colony-stimulating factor. Growth hormone showed only minimal or no significant effects, and the therapy of secondary chronic SCI with riluzole has been poorly researched to date.

RESUMEN

BACKGROUND: Insomnia is a prevalent condition in Australia that increases the risk of depression and anxiety symptoms. Cognitive behaviour therapy for insomnia (CBT-i) is the recommended 'first line' treatment but is accessed by a minority of people with insomnia. AIMS: To improve CBT-i access in Australia, we aimed to develop and test a self-guided interactive digital CBT-i program. METHODS: An online randomised controlled trial was conducted from August 2022 to August 2023 to investigate the effect of digital CBT-i, versus digital sleep education control, on symptoms of insomnia (ISI), depression (PHQ-9), anxiety (GAD-7), fatigue, sleepiness and maladaptive beliefs about sleep at 8-week follow-up. The control group accessed the intervention after the 8-week follow-up. Questionnaires were additionally administered at 16 and 24 weeks. Intent-to-treat mixed models and complete-case chi-squared analyses were used. RESULTS: Participants included 62 adults with insomnia symptoms (age M (SD) = 52.5 (16.3), 82% female, ISI = 18.6 (2.9)). There were no between-group differences in baseline characteristics or missing 8-week data (14.5%). After adjusting for baseline scores, CBT-i was associated with lower insomnia (Diffadj (95% CI) = 7.32 (5.0-9.6), P < 0.001, d = 1.64), depression (3.36 (1.3-5.4), p = 0.002, d = 0.84), fatigue (5.2 (2.5-7.9), P < 0.001, d = 1.00) and maladaptive beliefs about sleep (11.0 (4.1-18.0), P = 0.002, d = 0.82), but not anxiety symptoms at 8 weeks (1.84 (-0.1 to 3.8), p = 0.060, d = 0.50). Compared to control, CBT-i was associated with greater rates of insomnia remission (ISI <8; 0.0%, vs 40.0%, P < 0.001) and response at 8 weeks (ISI reduction ≥6; 7.1% vs 72.0%, P < 0.001). Improvements in insomnia and depression were maintained at 24 weeks in the CBT-i group. CONCLUSIONS: This interactive digital CBT-i program resulted in large and sustained improvements in symptoms of insomnia, depression, fatigue and maladaptive beliefs about sleep in Australian adults with insomnia symptoms. Implementation programs are required to increase digital CBT-i access and uptake.

RESUMEN

Dicaffeoylquinic acids (DCQAs) are polyphenolic compounds found in various medicinal plants such as Echinacea species and Hedera helix, whose multi-constituent extracts are used worldwide to treat respiratory diseases. Besides triterpenes, saponins, alkamides, and other constituents, DCQAs are an important group of substances for the pharmacological activity of plant-derived extracts. Therefore, the pharmacological properties of DCQAs have been studied over the last decades, suggesting antioxidative, anti-inflammatory, antimicrobial, hypoglycaemic, cardiovascular protective, neuroprotective, and hepatoprotective effects. However, the beneficial pharmacological profile of DCQAs has not yet been linked to their use in treating respiratory diseases such as acute or even chronic bronchitis. The aim of this review was to assess the potential of DCQAs for respiratory indications based on published in vitro and in vivo pharmacological and pre-clinical data, with particular focus on antioxidative, anti-inflammatory, and respiratory-related effects such as antitussive or antispasmodic properties. A respective literature search revealed a large number of publications on the six DCQA isoforms. Based on this search, a focus was placed on 1,3-, 3,4-, 3,5-, and 4,5-DCQA, as the publications focused mainly on these isomers. Based on the available pre-clinical data, DCQAs trigger cellular mechanisms that are important in the treatment of respiratory diseases such as decreasing NF-κB activation, reducing oxidative stress, or activating the Nrf2 pathway. Taken together, these data suggest an essential role for DCQAs within herbal medicines used for the treatment of respiratory diseases and highlights the need for the identifications of DCQAs as lead substances within such extracts.

RESUMEN

Endoscopic cholangiopancreatography (ERCP) is a widely used diagnostic and therapeutic tool for pancreaticobiliary conditions. One of its major complications is pancreatitis. This study aims to understand the incidence of post-ERCP pancreatitis after using rectal diclofenac and Indomethacin as prophylactic measures. We retrieved 2870 articles from the PubMed, ScienceDirect, and Google Scholar databases. Using the Medical Subject Headings (MeSH) strategy in PubMed, we chose research articles published in the last five years. Exclusion criteria included paid full-text articles, abstracts, letters to editors, patients not undergoing ERCP, ages more than 45 years, animal studies, and non-English studies. The 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) criteria were used in the design of our systematic reviews. It was found that the medical world is still debating whether rectal diclofenac and Indomethacin are beneficial in avoiding post-ERCP pancreatitis (PEP). Rectal diclofenac is used. Although its effectiveness is debated due to mixed findings and concerns about certain outcomes, it is also considered beneficial in specific circumstances, such as before ERCP. Studies on rectal Indomethacin also yield contradictory results; while some emphasize the drug's large reduction in PEP incidence, especially in low-risk people, others question its efficacy. We need further studies to clarify the remaining uncertainties.

RESUMEN

Background Dental fear and anxiety are significant issues among pediatric patients, often complicating dental treatments. Various tools measure these emotional responses, including subjective scales such as the Visual Facial Anxiety Scale (VFAS) and Children Fear Scale (CFS), and objective scales such as Venham's Anxiety Scale (VAS) and Frankl Behavior Rating Scale (FBRS). This study explores the association between these measures in children subjected to brainwave entrainment (BWE) therapy. This study aimed to evaluate the association between subjective and objective fear and anxiety measures in pediatric dental patients within both the brainwave entrainment (BWE) intervention group and control group. Methods This randomized controlled trial included pediatric participants aged seven to 12 years reporting to the department for dental treatment. Participants were randomized into two following groups: an experimental group receiving BWE therapy and a control group receiving traditional behavioral management. Fear and anxiety levels were measured using subjective and objective scales before and after the intervention. Data were analyzed using Spearman's correlation to examine the associations between these scales, with statistical significance set at p<0.05. Results Post-intervention analysis revealed significant correlations between subjective and objective measures of fear and anxiety in both groups. In the BWE group (N=126), there was a moderate positive correlation between the VFAS and VAS (rho=0.540, p<0.001) and a strong negative correlation between the CFS and FBRS (rho=-0.666, p<0.001). The control group (N=126) showed stronger correlations, rho=0.778 for anxiety scales and rho=-0.817 for fear and behavior scales (p<0.001). Combined data analysis from both groups (N=252) confirmed strong correlations. Conclusion This study found a significant association between subjective and objective measures of fear and anxiety in pediatric dental patients within both the brainwave entrainment (BWE) intervention group and control group. Thereby proving that self-reporting behavioral scales are useful for quickly assessing anxiety in pediatric dental settings.

RESUMEN

Colorectal cancer (CRC), as the third most common bisexual cancer worldwide, requires urgent research on its underlying mechanisms and intervention methods. NRF2 is an important transcription factor involved in the regulation of redox homeostasis, protein degradation, DNA repair, and other cancer processes, playing an important role in cancer. In recent years, the complex role of NRF2 in CRC has been continuously revealed: on the one hand, it exhibits a chemopreventive effect on cancer by protecting normal cells from oxidative stress, and on the other hand, it also exhibits a protective effect on malignant cells. Therefore, this article explores the dual role of NRF2 and its related signaling pathways in CRC, including their chemical protective properties and promoting effects in the occurrence, development, metastasis, and chemotherapy resistance of CRC. In addition, this article focuses on exploring the regulation of NRF2 in CRC ferroptosis, as well as NRF2 drug modulators (activators and inhibitors) targeting CRC, including natural products, compounds, and traditional Chinese medicine formulations.

RESUMEN

BACKGROUND: Areca nut, the fruit of A. catechu, is an important Chinese herbal medicine and is the first of China's "four southern medicines". The main chemical components are alkaloids, phenols, polysaccharides, amino acids, and terpenoids. The flowers, leaves, fruits and seeds of A. catechu contain high medicinal value. However, with the emergence of adverse reactions in people who chew areca nut, people have doubts about the safety of the use of areca nut. PURPOSE: In view of the two sides of pharmacology and toxicology of areca nut, this study comprehensively reviewed the components of different parts of A. catechu, the mechanism of pharmacology and toxicology, and the relationship between dosage and pharmacology and toxicology, in order to provide a new reference for the safe application of areca nut. METHODS: We used "Areca nut", "Betel nut", and known biologically active ingredients in areca nut, combined with "natural active ingredients", "pharmacological activity", and "toxicological effect" as keywords to search in PubMed, Web of Science, Science Direct and CNKI up to March 2024. RESULTS: A large number of studies have shown that low-dose areca nut has pharmacological effects such as deworming, anti-inflammatory, improving gastrointestinal function, lowering blood lipids, preventing atherosclerosis, anti-depression properties. The important mechanism involved in these effects is to reduce the generation of ROS, inhibit the activation of NADPH oxidase, increase the activity of antioxidant enzymes, affect MAPK, AKT, TLR, NF-κB, Nrf-2, PI3 K, STAT3 signaling pathway, reduce COX-2, IL-1ß m RNA, MCP-1 and ICAM-1 mRNA gene expression, reduce IL-6, IL-8, IGE levels, activate AMPK signaling pathway, change the ion level in cells, and increase Bax/Bcl-2 ratio. It interferes with the biochemical metabolic process of bacteria. Long-term consumption of areca nut in large quantities will cause some adverse reactions or related malignant diseases to the human body. CONCLUSION: We reviewed the pharmacological and toxicological effects and related mechanisms of areca nut, revealed the relationship between dose and pharmacological and toxicological effects, and discussed how to reduce the toxicity of areca nut and improve the comprehensive utilization of areca nut. It provides a reference for the study of the relationship between areca nut and human health, as well as the safe and rational use and full development and utilization of areca nut.

RESUMEN

INTRODUCTION: Incorporating rare and threatened healing plants from Traditional Chinese Medicine (TCM) into modern medicine is a hopeful way to expand treatment choices and encourage the long-term use of plant resources. These plants have been used in Traditional Chinese Medicine for a long time. They have powerful healing properties, including the ability to reduce inflammation and fight cancer. They also protect nerves and the heart. METHOD: A thorough study of all the scientific studies, clinical trials, ethnobotanical surveys, and conservation reports that were found were all looked at in relation to rare and threatened medical plants used in TCM. We looked through databases like PubMed, Scopus, and Web of Science for relevant pieces. Studies published in peer-reviewed journals, reports from reputable conservation organisations, and written down traditional knowledge were all considered to be relevant. RESULTS: Key results show that plants like Dendrobium, Panax notoginseng, Taxus chinensis, and Cistanche deserticola can be used as medicines and that there are good ways to protect them. Some of the conservation methods that have been named are agroforestry, community-based management, current breeding techniques, and sustainable gathering. Collaboration in research, clinical trials, personalised medicine, regulatory harmonisation, and public education programs are all part of the integration with modern medicine. These programs try to solve problems like scientific proof, protection, and cultural integration. CONCLUSION: When rare and threatened medical plants from Traditional Chinese Medicine (TCM) are used in modern medicine, it can improve health and help protect wildlife. Using both old information and new science discoveries together can lead to new treatments and long-term uses for these plant materials. Large-scale clinical studies, new ways of growing plants, and looking into how TCM herbs and regular drugs can work together should be the main topics of future study. For global healthcare to improve and for these important plant resources to be used in the long term, academics, healthcare workers, lawmakers, and local communities must work together.

RESUMEN

BACKGROUND: Pulmonary hypertension (PH) is a progressive and life-threatening disorder characterized by elevated pulmonary arterial pressure, leading to right heart failure and reduced exercise capacity. Traditional pharmacological and surgical treatments offer limited efficacy and significant side effects, necessitating the exploration of alternative therapeutic options. OBJECTIVE: This systematic review and meta-analysis aimed to evaluate the efficacy and safety of non-pharmacological interventions, including exercise, dietary modifications, and psychosocial therapies, in the management of pulmonary hypertension. METHODS: Comprehensive searches were conducted in PubMed, Cochrane Library, and Scopus up to 2024, identifying randomized controlled trials and observational studies examining non-pharmacological interventions for PH. Primary outcomes assessed included pulmonary arterial pressure, right heart function, exercise capacity, and quality of life, with secondary analysis on safety and adverse effects. Data synthesis was performed using random-effects meta-analysis. RESULTS: The review included 30 studies, totaling 2000 participants with various forms of PH. Meta-analysis demonstrated significant improvements in exercise capacity as measured by the 6 min walk distance (mean increase of 45 meters, 95 % CI: 30-60, p<0.001), enhanced quality of life scores, and reduction in pulmonary arterial pressure (mean reduction of 5 mmHg, 95 % CI: 3-7, p<0.01). Non-pharmacological therapies also showed a favorable safety profile, with minor adverse effects reported. CONCLUSION: Non-pharmacological interventions provide a viable and effective complement to traditional treatments for pulmonary hypertension, significantly improving functional capacity and hemodynamic parameters without severe adverse effects. These findings support the integration of tailored non-pharmacological strategies into the therapeutic regimen for PH patients, emphasizing the need for broader implementation and further research to optimize intervention protocols.

RESUMEN

The high prevalence of acute kidney injury (AKI) in ICU patients emphasizes the need to understand factors influencing continuous renal replacement therapy (CRRT) circuit lifespan for optimal outcomes. This review examines key pharmacological interventions-citrate (especially in regional citrate anticoagulation), unfractionated heparin (UFH), low molecular weight heparin (LMWH), and nafamostat mesylate (NM)-and their effects on filter longevity. Citrate shows efficacy with lower bleeding risks, while UFH remains cost-effective, particularly in COVID-19 cases. LMWH is effective but associated with higher bleeding risks. NM is promising for high-bleeding risk scenarios. The review advocates for non-tunneled, non-cuffed temporary catheters, especially bedside-inserted ones, and discusses the advantages of surface-modified dual-lumen catheters. Material composition, such as polysulfone membranes, impacts filter lifespan. The choice of treatment modality, such as Continuous Veno-Venous Hemodialysis (CVVHD) or Continuous Veno-Venous Hemofiltration with Dialysis (CVVHDF), along with the management of effluent volume, blood flow rates, and downtime, are critical in prolonging filter longevity in CRRT. Patient-specific conditions, particularly the type of underlying disease, and the implementation of early mobilization strategies during CRRT are identified as influential factors that can extend the lifespan of CRRT filters. In conclusion, this review offers insights into factors influencing CRRT circuit longevity, supporting evidence-based practices and suggesting further multicenter studies to guide ICU clinical decisions.

RESUMEN

Background: Endometritis seriously affects maternal reproductive health and fertility. Natural compounds have the characteristics of high efficiency and low residue in disease treatment. We aimed to discover and reveal the pharmacological effects of naringin, which is widely present in food and plants, on endometritis. Methods: Based on network pharmacology, the potential targets and pathways of naringin's actions on endometritis were predicted. Animal in vivo experiments were conducted to examine the inflammatory response of lipopolysaccharides (LPSs) in uterine tissue and the therapeutic effect of naringin. An in vitro primary bovine endometrial epithelial cell inflammation and drug treatment model was constructed. The production of reactive oxygen species (ROS) was measured using DCFH-DA, and the effect of naringin on LPS-induced endometritis was evaluated using HE staining, real-time quantitative PCR, Western blot, and immunofluorescence staining methods. Results: Naringin alleviated LPS-induced inflammatory injury and oxidative stress in the endometrium of mice and bovine endometrial epithelial cells (bEECs). Furthermore, in vitro studies were carried out to reveal the potential anti-inflammatory mechanisms of naringin based on network pharmacology. We found that naringin significantly inhibited LPS-stimulated endoplasmic reticulum stress (ERS)-related gene and protein expression, thus reducing the unfolded protein response (UPR). Furthermore, treatment of naringin attenuated the autophagic flux induced by ERS. In a further study, we observed that PI3K/AKT pathway inhibitors or ERS inducers partially reverse naringin's inhibition of autophagy and cell apoptosis. Conclusion: It is demonstrated that naringin suppresses autophagy by directly inhibiting the ERS-PI3K/AKT axis and exerting anti-inflammatory and antioxidant effects in endometritis. These findings provide novel insights into the pathogenesis of endometritis, highlighting potential therapeutic targets of traditional herbs and compounds.

RESUMEN

In recent years, the idea of medicine and food homology (MFH), which highlights the intimate relationship between food and medicine, has gained international recognition. Specifically, MFH substances have the ability to serve as both food and medicine. Many foods have been reported to have good nutritional and medical values, not only for satiety but also for nourishing the body and treating diseases pharmacologically. As modern scientific research has progressed, the concept of MFH has been emphasized and developed in a way that has never been seen before. Therefore, in this paper, we reviewed the development history of MFH substances, summarized some typical bioactive ingredients, and recognized pharmacological effects. In addition, we further discussed the application of MFH substances in the food field, with the goal of providing ideas and references for the research and development of MFH in the food industry as well as the progress of related industries.
