Inhibition of Colorectal Cancer Metastasis by Total Flavones of Abelmoschus Manihot via Lncrna AL137782-mediated STAT3/EMT Pathway Regulation.

Colorectal cancer (CRC) ranks among the most lethal malignancies globally, particularly following metastasis which results in poor prognosis. In recent years, CRC incidence in China has persistently increased. Total flavonoids (TFA) from Abelmoschus manihot, a natural compound, are recognized for their anti-inflammatory, analgesic, and antioxidant properties. However, despite extensive research into the therapeutic potential of TFA, coverage of its role in cancer treatment is notably lacking. To address this research void, our study aims to unveil the role and potential mechanisms of TFA in treating CRC. We conducted a series of experiments to assess the impact of TFA on CRC cells. Two specific CRC cell lines, DLD-1 and HCT116, were employed in cell proliferation, colony formation, flow cytometry, and cell migration assays. Additionally, to test the in vivo effects of TFA, we developed a nude mouse xenograft tumor model to assess TFA's impact on tumor growth and liver metastasis. Furthermore, we meticulously analyzed the gene expression differences between CRC cells pretreated with TGF-β and those treated with TFA using RNA-seq technology. We also examined the molecular mechanisms of TFA and assessed the expression of proteins related to the STAT3/EMT signaling pathway through Western blotting and siRNA technology. Our research findings reveal for the first time the effect of TFA on CRC cells. Result shows that TFA could suppress cell proliferation, migration, and induce apoptosis. In vivo results showed that TFA inhibited tumor growth and liver metastasis. Molecular mechanism studies have shown that TFA exerts these effects by upregulating the expression of non-coding RNA AL137782, inhibiting the EMT/STAT3 signaling pathway. These results suggest that TFA is a potential candidate for mitigating CRC metastasis. However, further research is needed to comprehensively evaluate the efficacy and safety of TFA in animal models and clinical settings. These findings bring great hope for the development of innovative CRC treatment methods.

Knowledge and Attitudes of Medical and Pharmacy Graduates about Opioids Prescription and Dispensation in 2022 in Bamako, Mali

Opioids are medications with analgesic properties used primarily as painkillers. Nowadays, off-label uses (non-medical use, prolonged use, misuse and use without a medical supervision) are common inducing drug dependence with harmful consequences including substance-induced psychosis or pharmacopsychosis. In a cross-sectional study from February to June 2021, we used a questionnaire to collect information on the knowledge of interns and doctors trained in the Faculty of Medicine and Dental Medicine and the Faculty of Pharmacy at the University of Sciences, Bamako Techniques and Technologies (USTTB) on opioids in eight (8) public health facilities (5 university hospitals and 3 district hospitals) in Bamako.

Therapeutic Potential of Olax subscorpioidea Root Extracts in Managing Inflammatory Conditions: A Preclinical Study

Olax subscorpioidea, a plant species endemic to tropical Africa, has long been utilized in traditional medicine for its purported anti-inflammatory and analgesic properties. This preclinical study evaluates the therapeutic potential of Olax subscorpioidea root extracts in managing inflammatory conditions, specifically in a Freund’s adjuvant (CFA)-collagen type II induced arthritis model in albino rats. Both aqueous and ethanol extracts were prepared and assessed for their effects on inflammatory parameters, including cytokine levels, paw edema, joint swelling, and histopathological changes. The study found that both extracts significantly reduced inflammation and clinical signs of arthritis, with the ethanol extract demonstrating a broader range of bioactive compounds and potentially greater efficacy. Mechanistic insights suggest that the extracts exert their effects through inhibition of pro-inflammatory enzymes, modulation of cytokine production, and enhancement of antioxidant activity. Safety and toxicity assessments confirmed the non-toxic nature of the extracts at tested doses. These findings validate the traditional use of Olax subscorpioidea for inflammatory conditions and support its potential integration into modern therapeutic regimens. Future research should focus on dosage optimization, long-term effects, and clinical trials to further establish the efficacy and safety of Olax subscorpioidea root extracts in human subjects.

Shenqi Pill alleviates acetaminophen-induced liver injury: a comprehensive strategy of network pharmacology and spectrum-effect relationship reveals mechanisms and active components

BackgroundAcetaminophen (APAP), commonly used for its antipyretic and analgesic properties, can cause severe liver injury or even acute liver failure when overdosed. However, the options for treating APAP-induced liver toxicity are limited. Shenqi Pill (SQP), a traditional Chinese herbal formula, has shown effectiveness in treating various liver ailments. SQP consists of cinnamon, aconite, rehmannia, cornus, peony bark, Chinese yam, poria, and alisma in a ratio of 1:1:8:4:3:4:3:3. However, the mechanisms and active components of SQP that counteract drug-induced liver injury (DILI) are not well understood. PurposeThis study aimed to explore the protective effects of SQP against APAP-induced liver injury in both laboratory and animal settings. It seeks to identify the active components and potential mechanisms by which SQP targets mitochondria to alleviate liver damage. MethodsA mouse model with APAP-induced liver injury was established to assess SQP's therapeutic impact. This study then analyzed the components of SQP using UPLC-Q-TOF-MS in both in vivo and in vitro environments. Network pharmacology and the GEO database helped predict potential pathways and targets. Potential active components were identified through spectrum-effect relationship analysis and validated their efficacy using Seahorse assays and molecular docking. ResultsTreatment with SQP significantly reduced liver dysfunction, tissue damage, lipid metabolic disruptions, and inflammation caused by APAP in mice. In cellular tests, SQP-treated serum notably enhanced mitochondrial function, maintained membrane potential, decreased ROS levels, and prevented mitochondrial permeability transition pore opening. Biochemically, SQP reversed the suppression of p-AMPK, p-ACC, CPT1, and ACADM expression caused by APAP overdose. This study identified 97 in vitro and 24 in vivo components of SQP, with eight showing significant mitochondrial benefits. Molecular docking studies suggest that fuziline and paeoniflorin could activate AMPK. ConclusionSQP effectively mitigates APAP-induced liver injury by enhancing mitochondrial function via the AMPK-ACC-CPT1-ACADM pathway. Moreover, this study introduces a novel strategy for analyzing the relationship between the chemical and pharmacological properties of drug-containing serum, successfully identifying compounds with mitochondrial activity. Fuziline and paeoniflorin, in particular, emerge as promising mitochondrial protectants and warrant further investigation. This research underpins the development of innovative treatments for DILI using SQP and its components.

A cutting-edge new framework for the pain management in children: nanotechnology.

Pain is a subjective concept which is ever-present in the medical field. Health professionals are confronted with a variety of pain types and sources, as well as the challenge of managing a patient with acute or chronic suffering. An even bigger challenge is presented in the pediatric population, which often cannot quantify pain in a numerical scale like adults. Infants and small children especially show their discomfort through behavioral and physiological indicators, leaving the health provider with the task of rating the pain. Depending on the pathophysiology of it, pain can be classified as neuropathic or nociceptive, with the first being defined by an irregular signal processing in the nervous system and the second appearing in cases of direct tissue damage or prolonged contact with a certain stimulant. The approach is generally either pharmacological or non-pharmacological and it can vary from using NSAIDs, local anesthetics, opiates to physical and psychological routes. Unfortunately, some pathologies involve either intense or chronic pain that cannot be managed with traditional methods. Recent studies have involved nanoparticles with special characteristics such as small dimension and large surface area that can facilitate carrying treatments to tissues and even offer intrinsic analgesic properties. Pediatrics has benefited significantly from the application of nanotechnology, which has enabled the development of novel strategies for drug delivery, disease diagnosis, and tissue engineering. This narrative review aims to evaluate the role of nanotechnology in current pain therapy, with emphasis on pain in children.

Role of l -arginine/nitric oxide/cyclic GMP/K ATP channel signaling pathway and opioid receptors in the antinociceptive effect of rutin in mice.

The l -arginine ( l -Arg)/nitric oxide/cyclic GMP/potassium channel (K ATP ) pathway and opioid receptors are known to play critical roles in pain perception and the antinociceptive effects of various compounds. While there is evidence suggesting that the analgesic effects of rutin may involve nitric oxide modulation, the direct link between rutin and the l -Arg/nitric oxide/cyclic GMP/K ATP pathway in the context of pain modulation requires further investigation. The antinociceptive effect of rutin was studied in male NMRI mice using the formalin test. To investigate the role of the l -Arg/nitric oxide/cyclic GMP/K ATP pathway and opioid receptors, the mice were pretreated intraperitoneally with different substances. These substances included l -Arg (a precursor of nitric oxide), S-nitroso- N -acetylpenicillamine (SNAP, a nitric oxide donor), N(gamma)-nitro- l -arginine methyl ester (L-NAME, an inhibitor of nitric oxide synthase), sildenafil (an inhibitor of phosphodiesterase enzyme), glibenclamide (a K ATP channel blocker), and naloxone (an opioid receptor antagonist). All pretreatments were administered 20 min before the administration of the most effective dose of rutin. Based on our investigation, it was found that rutin exhibited a dose-dependent antinociceptive effect. The administration of SNAP enhanced the analgesic effects of rutin during both the initial and secondary phases. Moreover, L-NAME, naloxone, and glibenclamide reduced the analgesic effects of rutin in both the primary and secondary phases. In conclusion, rutin holds significant value as a flavonoid with analgesic properties, and its analgesic effect is directly mediated through the nitric oxide/cyclic GMP/K ATP channel pathway.

A Review on Analgesic and Anti-inflammatory Activities of Traditional Medicinal Plants

A wide range of potential drugs candidates can be found in medicinal plants with therapeutic potential. One of the primary categories of disorders that are common is inflammation, which includes rheumatism and arthritis. The majority of non-steroidal anti-inflammatory medications on the market work effectively for joint inflammation, but they have no gastroprotective qualities. Numerous undesirable side effects are displayed by NSAIDs, opiates, and other anti-inflammatory and analgesic medications. Therefore, there must be an emergence in order to produce new active molecules with a minimum of side effects. Many substances, interfering with the inflammatory response have been isolated from medicinal plants. The purpose of this study is to provide an in-depth review of plant species that have anti-inflammatory and analgesic properties.

Evaluation of Hydrazide-hydrazone and 4-thiazolidinone Derivatives of Etodolac as Potential Anticancer Agents in Leukemia Cells

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs), which are commonly used for their anti-inflammatory and analgesic properties, have also been found to prevent cancer. (±)(R,S) Etodolac is an NSAID that belongs to the class of cyclooxygenase-2 inhibitors. Various derivatives of etodolac are synthesized to boost its anti-proliferative action and lessen its potential negative effects. In our earlier studies, some novel derivatives of etodolac exhibited stronger cytotoxic effects on prostate cell lines and had similar effects on leukemia cells in pre-screening experiments. Objective: Using the K562 leukemia cell line as a model, we sought to investigate the anti-cancer properties of a hydrazide-hydrozone derivative (SGK-205) and a 4-thiazolidinone derivative of etodolac (SGK-216). Materials and Methods: In the current investigation, SGK-205 and SGK-216 compounds were administered to K562 cells for 24 and 48 hours at concentrations of 10, 25, 50, 75 and 100 μM. Cell viability was assessed using the MTT test, and apoptosis by Annexin V-PI staining and mitochondrial membrane potential assays, together with mRNA expressions of apoptotic proteins. The levels of the proteins, HER2 and COX2, were also examined to evaluate COX2 inhibitory capacity. Results: In K562 cells, there was a definite dose-dependent response to SGK-205 and SGK-216 compounds. Results from MTT viability tests, together with mitochondrial membrane potential measurements and Annexin V-PI staining, revealed that SGK-216 and SGK-205 significantly outperformed etodolac in terms of their apoptotic and anti-proliferative activities. The concentration range of 10-20 M for both chemicals was sufficient to start biological responses. Apoptosis was also investigated through the expressions of pro- and anti-apoptotic proteins. Additionally, gene expression research demonstrated SGK-205 to be a beneficial substitute to etodolac in lowering COX-2 and human epidermal growth factor receptor-2 (HER2) expression. Conclusion: Our data indicated both derivatives to have higher anti-proliferative and apoptotic effects compared to etodolac. An overall assessment highlighting apoptotic induction potential, acceptable toxicity levels, a consistent dose-response relationship, and COX2 inhibitory actions, in particular, indicated SGK-205 as a viable novel therapeutic.

Indomethacin inhibits human seasonal coronaviruses at late stages of viral replication in lung cells: Impact on virus-induced COX-2 expression

Coronaviruses (CoV), zoonotic viruses periodically emerging worldwide, represent a constant potential threat to humans. To date, seven human coronaviruses (HCoV) have been identified: HCoV-229E, HCoV-NL63, HCoV-OC43 and HCoV-HKU1, globally circulating in the human population (seasonal coronaviruses, sHCoV), and three highly-pathogenic coronaviruses, SARS-CoV, MERS-CoV and SARS-CoV-2. Although sHCoV generally cause only mild respiratory diseases, severe complications may occur in specific populations, highlighting the need for broad-spectrum anti-coronavirus drugs. Herein we show that indomethacin (INDO), a non-steroidal anti-inflammatory drug widely used in the clinic for its potent anti-inflammatory and analgesic properties, effectively inhibits the replication of Alpha-coronavirus HCoV-229E and Beta-coronavirus HCoV-OC43 in human lung-derived cells. Indomethacin does not interfere with HCoV binding or entry into target cells, but acts at late stages of the virus life cycle, inhibiting viral RNA synthesis and infectious viral particles production. Although INDO anti-inflammatory action is mediated by blocking cyclooxygenase-1 and -2 (COX-1/2) enzymatic activity, the antiviral effect appears to be cyclooxygenase-independent and is not mimicked by the potent COX-1/2 inhibitor aspirin. Interestingly we found that both seasonal HCoVs markedly (>100 fold) induce the expression of the pro-inflammatory mediator COX-2 in lung cells; notably, INDO-treatment was found to effectively inhibit virus-induced COX-2 expression at the transcriptional level, revealing an additional mechanism to prevent COX-2-mediated inflammatory reactions in HCoV-infected lung cells, besides COX activity inhibition. Altogether the results indicate that indomethacin, possessing both potent anti-inflammatory properties and a direct antiviral activity against HCoV, could be effective in the treatment of Alpha- and Beta-coronavirus infections.

Purpose, and DesignKnee osteoarthritis (OA) is one of the most common and debilitating diseases, especially in the elderly. Hemp seed oil is a plant product that has been used as a food or drug since ancient times because of its anti-inflammatory and analgesic properties. MethodsA double-blind, active, placebo-controlled trial was done to assess the efficacy of hemp seed oil on knee OA. Ninety patients were randomly allocated to three groups; hemp seed oil, diclofenac gel, and placebo via a blocked randomization method, and were asked to apply the topical treatment daily for 2 months. The study participant underwent assessments before, and four and 8 weeks after the intervention. Evaluation included measurements of the heel-to-thigh distance, utilization of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and application of visual analog scale (VAS). Data analysis was performed using SPSS.24 and the significance level was considered as p < .05. ResultsAll parameters, except heel-to-thigh distance, improved significantly in the hemp seed oil group compared to placebo group. Improvements in VAS and WOMAC parameters were not different comparing the hemp seed oil and diclofenac gel groups. Heel-to-thigh distance decreased significantly within all groups during the study. There were no significant differences in improvements in heel-to-thigh distance comparing the three groups. Conclusion, and Clinical ImplicationsHemp seed oil led to greater improvements in VAS pain score and WOMAC parameters, but not knee flexion range, compared to placebo. There were no differences in measured outcomes comparing hemp seed oil and diclofenac gel.

Quality control of traditional Chinese medicine Chelidonii herba based on 2D-Q-NMR

Chelidonii herba is a traditional Chinese medicinal herb with effects including antispasmodic, analgesic, antitussive, and bronchodilator properties. Alkaloids are the main bioactive ingredients in Chelidonii herba. In this study, a two-dimensional nuclear magnetic resonance (Heteronuclear Singular Quantum Correlation, HSQC-2D-NMR) technique was employed to quantitatively analyze the total alkaloid content and three major active alkaloid monomers in Chelidonii herba from eleven different sources. The quantification results of the three monomeric alkaloids were also verified using conventional quantitative control methods such as HPLC. Experimental findings indicate that the total alkaloid content is not directly correlated with the content of the three monomeric alkaloids. Furthermore, the content of any individual monomeric alkaloid does not accurately reflect the overall quality of Chelidonii herba. It was demonstrated that the 2D-Q-NMR NMR can be applied as an alternative method. While maintaining the same levels of accuracy and precision, the 2D-Q-NMR method is simpler to operate and provides more comprehensive results with higher reproducibility in some cases.

Uncoupling the CRMP2-CaV2.2 Interaction Reduces Pain-Like Behavior in a Preclinical Joint-Pain Model

Osteoarthritis (OA) represents a significant pain challenge globally, as current treatments are limited and come with substantial and adverse side effects. Voltage-gated calcium channels have proved to be pharmacologically effective targets, with multiple Food and Drug Administration-approved CaV2.2 modulators available for the treatment of pain. Although effective, drugs targeting CaV2.2 are complicated by the same obstacles facing other pain therapeutics—invasive routes of administration, narrow therapeutic windows, side effects, and addiction potential. We have identified a key regulator of CaV2.2 channels, collapsin response mediator protein 2, that allows us to indirectly regulate CaV2.2 expression and function. We previously developed a peptidomimetic modulator of collapsin response mediator protein 2, CBD3063, that effectively reverses neuropathic and inflammatory pain without negative side effects by reducing membrane expression of CaV2.2. The potent analgesic properties of CBD3063, combined with the lack of negative side effects, prompted us to assess the efficacy of CBD3063 in a rodent model of OA pain. Here, we demonstrate the intraperitoneal administration of CBD3063 alleviates both evoked and nonevoked behavioral hallmarks of OA pain. Further, we reveal that CBD3063 reduces OA-induced increased neural activity in the parabrachial nucleus, a key supraspinal site modulating the pain experience. Together, these studies suggest that CBD3063 is an effective analgesic for OA pain. PerspectiveDespite the high prevalence of OA pain worldwide, current treatment options remain limited. We demonstrate that CBD3063-mediated disruption of the CaV2.2-collapsin response mediator protein 2 interaction alleviates pain in a preclinical joint pain model, providing a promising basis for the development of new OA pain treatments.

Xylazine-Ketamine Outperforms Diazepam-Ketamine in Rabbit Anesthesia

Background: Limited research on the effects of ketamine combinations on rabbit anesthesia underscores the need for safe and effective injectable methods. Specific Background: This study compares the efficacy and safety of two anesthetic combinations—xylazine-ketamine and diazepam-ketamine —in rabbits to address this gap. Knowledge Gap: Ketamine combinations are commonly used in rabbits, but there is limited data on their effects on analgesic properties and anesthesia duration. Aims: The study assesses the onset of righting reflex loss, analgesia duration, recumbency duration, and standing attempts in rabbits treated with XK and DK. Results: Ten healthy rabbits were administered XK (5 mg xylazine and 10 mg ketamine per kg) or DK (1 mg diazepam and 30 mg ketamine per kg) intramuscularly. The study found no significant difference in OLRR between the groups. Only XK produced significant analgesia (OA: 4.5±0.2 min, DA: 45.1±1.9 min), while DK showed no analgesic effect. DR and ATS were significantly shorter in XK (56.1±3.1 min and 7.3±0.7 min) compared to DK (121.1±7.5 min and 25.3±1.2 min). Novelty: The study compares XK and DK in rabbits, finding XK provides superior analgesia and faster recovery times, while DK is ineffective for pain management. Implications: The study indicates that XK is more effective for analgesic procedures, while DK is recommended for painful treatments with additional analgesics. Highlights: XK Provides Analgesia: Only Xylazine-Ketamine offers significant pain relief. Shorter Recovery Time: XK results in quicker recovery compared to DK. DK Needs Supplement: Diazepam-Ketamine requires additional analgesics for pain management. Keywords: Anesthesia, Xylazine-Ketamine, Diazepam-Ketamine, Rabbits, Analgesia

Rapid mitragynine quantification and fingerprinting of products from Mitragyna speciosa Korth. leaf (Kratom) using high-performance thin-layer chromatography.

Kratom (leaves from Mitragyna speciosa Korth.; Rubiaceae) is a herbal medicine known for its analgesic properties and psychoactive effects. Kratom in Thailand is currently legal; however, it is prohibited in some countries and considered a narcotic plant. Our aim was to establish a reliable, simple, and rapid method for quantifying mitragynine in Kratom leaves and related products through a combination of high-performance thin-layer chromatography (HPTLC) and densitometry. A densitometric HPTLC method was developed and validated in terms of specificity, linearity, limit of detection (LOD), limit of quantification (LOQ), accuracy, precision, and robustness. The fingerprints of kratom leaves, Mitragyna spp., and related products were constructed. For HPTLC, samples were applied to silica gel 60 F254 plates, and the mobile phase comprised n-hexane, ethyl acetate, and triethylamine (1:1:0.15, v/v/v). Densitometric detection was carried out under ultraviolet light at a wavelength of 226 nm. The validated method exhibited a range of 14.31-143.10 μg/mL, yielding a correlation coefficient of 0.9993. Spiked recovery rates were within a range of 98.3%-100.9%, and the LOD and LOQ were 3.80 and 11.53 μg/mL, respectively. Kratom samples were analyzed with the developed method, and the correlation coefficient was 0.9641, compared to the high-performance liquid chromatography-diode-array detection (HPLC-DAD) method. The HPTLC fingerprints displayed a distinctive pattern, facilitating discrimination among different plant parts and Mitragyna spp. The established method offers the advantages of simplicity, ease of use, and speed of analysis, serving as a practical alternative for mitragynine quantification in kratom leaf and its related products.
