To investigate the mechanism of Cistanche deserticola Ma (CDA) in the treatment of myocardial ischemia-reperfusion (I/R) injury by network pharmacology and cell experiments. The main active components of CDA were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). I/R-related targets were identified from DisGeNET, OMIMD, and TTD; the I/R protein–protein interaction (PPI) network was constructed using the STRING input. The targets of CDA that inhibit I/R injury in Matescape and Microshengxin were subjected to Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Cell viability, levels of lactate dehydrogenase (LDH), superoxide dismutase (SOD), and malondialdehyde (MDA), and protein expression of phosphatidylinositol 3-kinase (PI3K) and serine/threonine kinase 1 (Akt1) were determined. A total of 236 targets were identified, with PI3K, Akt, epithelial growth factor receptor (EGFR), and another kinase being the major targets, and according to GO and KEGG analysis, CDA was most likely to inhibit I/R through the PI3K-Akt pathway. The optimal concentration of 10% medicated serum of CDA was determined to be the most effective concentration. The levels of LDH and MDA were significantly decreased in the CDA and BEZ23 groups, but the levels of SOD were significantly increased, thereby alleviating cell damage. In addition, the expression of PI3K, Akt, and p-AKT proteins was significantly reduced in the CDA group. CDA alleviates I/R injury through antioxidation and inhibition of the PI3K/Akt signaling pathway.

Phytopathogenic fungi remain the main infectious agents in plants, causing severe damage to the environment and human health. Thus, to reduce the usage of synthetically derived fungicides and perform agricultural crop production, the search for new control strategies including plant extracts constitutes an eco-friendly and safe alternative. This study aimed to quantify the phytochemical constituents of the three plant ( Mentha pulegium L., Mentha spicata L., and Mentha longifolia L.) extracts and to screen their phytochemical composition including total phenolic (TPC), flavonoids (TFC) and condensed tannins contents (TCTC), and to evaluate their antioxidant activities. The efficacy of all mint extracts will be investigated against phytopathogenic fungal species. The three plant extracts were screened to assess their total phenolic, flavonoids, and condensed tannin contents using spectrophotometric assays. The antioxidant activities include 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferric ion reducing antioxidant power (FRAP), and β-carotene assays. The antifungal activities were investigated on phytopathogenic species including Botrytis cinerea, Fusarium culmorum, Fusarium oxysporum, Aspergillus niger, Aspergillus flavus, and Trichoderma sp. Quantitative analyses of phytochemical constituents of Mentha genus extracts revealed that both ethyl acetate (EtAc) and chloroformic (Chl) extracts are a rich source of phenols, flavonoids, and condensed tannins. Ethyl acetate extract of M. longifolia (EtAc L) displayed the highest content of phenols (69.9 ± 1.35 mg GAE/g DW) and flavonoids (53.26 ± 2.11 mg CE/g DW), while M. pulegium ethyl acetate extract (EtAc P) has the highest condensed tannins content (2.13 ± 0.4 mg CE/g DW). Moreover, the tested extracts exhibited potent antioxidant activities at low concentrations for EtAc L, followed by M. spicata (EtAc S), and EtAc P (IC50 = 35.76 ± 1.32 µg/mL for scavenging DPPH free radicals; EC50 527.96 ± 5.45 µg/mL for FRAP, and IC50 = 106.3 ± 3.75 µg/mL for β-carotene bleaching test). Finally, all tested extracts were able to inhibit the growth of several phytopathogenic micro-organisms on both agar and broth media. The Mentha extracts derived from the three mint species (i.e., L, P, and S) could be used for their antifungal activities to provide sustainable crop pest management.

Background: Epilepsy is a chronic neurological condition with various underlying mechanisms. It is known to affect a multitude of people across the globe, regardless of age and gender. Seizures associated with epilepsy involve the participation of stimulatory glutamatergic mechanisms along with inflammation and oxidative damage. Objectives: In this investigation, the anti-epileptic effect of scutellarein, a phytochemical compound isolated from Erigeron breviscapus (Vant.), has been evaluated in the pentylenetetrazol (PTZ) kindling epilepsy model in mice. Materials and Methods: The experimental mice were categorized into six groups with six animals in each. The first control group was given normal saline. The second group was provided only PTZ through an intraperitoneal route to induce seizures. The third and fourth groups received two oral doses of scutellarein (10 and 20 mg/kg) before 30 min of PTZ induction. Diazepam was intraperitoneally administered to the fifth group as a positive control. The impact of scutellarein on the duration and initiation of clonic and tonic convulsion, mortality, kindling, mobility, and immobility duration in PTZ-induced rodents was estimated. Also, the impact of scutellarein on oxidative stress markers and antioxidant and inflammatory marker levels was also evaluated. Results: Scutellarein treatment was able to reduce PTZ-induced seizures in mice. In PTZ animals, scutellarein lowered the seizure severity by suppressing the onset and duration of convulsions. Scutellarein successfully modulated the PTZ-provoked changes in gamma-aminobutyric acid (GABA), glutamate, and dopamine levels, as well as Ca2+ ATPase and Na+ K+ ATPase activity. Conclusion: Furthermore, it remarkably reduced the oxidative stress markers and decreased the contents of nuclear factor-kappa B (NF-κB), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) in PTZ animal brain tissues, confirming its anti-convulsant potential.

After hypovolemic shock caused by severe burns, lipid peroxidation is an important factor in tissue edema and multiorgan dysfunction syndrome (MODS). Many studies have shown that valproic acid (VPA) inhibits lipid peroxidation and reduces tissue and organ injury. This study investigated whether the VPA treatment of scalded rats reduced tissue edema by inhibiting lipid peroxidation, thereby improving organ function and survival rate. A total of 60 male Sprague-Dawley rats (weighing: 280–300 g) with a 50% total body surface area (TBSA) full-thickness dermal burn were randomly assigned to the following 3 groups (with 20 rats per group): (I) the no infusion resuscitation (NR) group; (II) the sodium lactate Ringer’s solution (LR) group; and (III) the sodium valproate Ringer’s solution (VR) group. After scalding, the following hemodynamic parameters were measured: Copper2+-Zinc2+-superoxide dismutase (Cu2+-Zn2+-SOD) activity, thiobarbituric acid reactive substances (TBARSs), oxidized glutathione (GSSG), reduced glutathione (GSH), and antioxidant enzyme activities. Organ function parameters and water content were also measured. Another 60 male Sprague-Dawley rats were used to observe the 24-h survival rate of the rats using the same scald model and fluid resuscitation. VPA significantly increased the mean arterial pressure (MAP) and cardiac output (CO), and significantly decreased the pulmonary vascular permeability index (PVPI) and extravascular lung water index (ELWI). VPA also increased plasma Cu2+-Zn2+-SOD activity and decreased the plasma TBARS level. VPA reduced the TBARS level and GSSG in various tissues and increased the concentration of GSH. VPA decreased glutathione peroxidase (GPx) and catalase (CAT) activity, but significantly increased glutathione reductase (GR) activity in various tissues. VPA significantly improved organ functions and decreased water content. VPA significantly improved the survival rate, and the 24-h survival rate of the VR group was double that of the LR group. Resuscitation with VPA reduced tissue edema, protected visceral functions, and improved the survival rate of rats with severe burn shock (BS) by alleviating lipid peroxidation.

In this study, the ultrahigh performance liquid chromatography mass spectrometry/mass spectrometry (UPLC-MS/MS) method was established to test the contents of protocatechuic acid (C7H6O4), salvianolic acid B (C36H30O16), rosmarinic acid (C19H14O3), and cryptotanshinone (C19H20O3) in Qishen Yiqi dripping pills. Methanol was chosen as the solvent according to a certain material–liquid ratio as a solution, and the ultrasonic extraction method was used to prepare the sample solution. UPLC-MS/MS was used to complete a quantitative analysis of the contents of Qishen Yiqi dripping pills. Then, the chromatographic conditions were shown as follows. The stationary phase was Agilent ZORBAX SB-C18 (2.1 mm × 100 mm, 1.8 µm), and the mobile phase was acetonitrile–0.1% formic acid water. The column temperature was 40℃, the injection volume was 3 µL, and the flow rate was 0.2 mL⋅min–1. Finally, the determination method was built to test four chemical constituents under the multiple reaction monitoring (MRM) analysis mode. The retention times of protocatechuic acid, salvianolic acid B, rosmarinic acid, and cryptotanshinone were 1.26, 1.32, 1.35, and 6.76 min, respectively. In addition, the concentration ranges of four compounds were 0.25–2.0 µg⋅mL–1, 10.0–50.0 µg⋅mL–1, 5.0–50.0 µg⋅mL–1, and 1.0–10.0 µg⋅mL–1, respectively. And the standard curve showed a good linear relationship in a reasonable range ( r2 ≥ 0.9950). The average recovery rate was from 96% to 124%. The contents of protocatechuic acid, salvianolic acid B, rosmarinic acid, and cryptotanshinone were 0.12%–0.022%, 17%–8.4%, and 6.5%–8.6% in seven batches of Qishen Yiqi dripping pills, which were in the range of 23%–31%. The instrument ran stably, and the method had good accuracy and repeatability (relative standard deviation [RSD] ≤ 3%). Additionally, the test result was stable within 10 h. The contents of the four constituents were different among different batches. The quantitative method was established to determine the four chemical components in Qishen Yiqi dripping pills, which could provide a reference for quality evaluation in vivo.

Several studies have demonstrated the anti-inflammatory properties of gastrodin. However, its specific role and mechanism in the context of osteoarthritis (OA) remain unclear. The objective of this study was to explore the function and mechanism of gastrodin in both in vivo and in vitro OA models. In this study, the targets of gastrodin against osteoarthritis were analyzed using bioinformatics methods. The effect of gastrodin on neutrophil infiltration and inflammatory cytokines in OA synovial tissue was evaluated using H&E staining. The levels of inflammatory cytokines were determined using ELISA and Q-PCR. The extracellular matrix degradation-related proteins and PI3K/AKT/FoxO1 signaling pathway were tested using western blotting. Bioinformatics analysis predicted that the target of gastrodin against OA might act on the FoxO pathway. The use of gastrodin resulted in a significant reduction in the infiltration of neutrophils in the synovial tissue of rats, as observed through H&E staining. Additionally, gastrodin was found to attenuate IL-1β-induced inhibition of chondrocyte viability, pro-inflammatory cytokine production, and extracellular matrix degradation. This effect can be attributed to the suppression of PI3K/AKT/FoxO1 by gastrodin. These findings indicate that gastrodin is a treatment for OA.
多项研究已经证明了天麻素的抗炎特性。然而，它在骨关节炎（OA）中的具体作用和机制仍不清楚。本研究的目的是探索天麻素在体内和体外 OA 模型中的功能和机制。本研究利用生物信息学方法分析了天麻素对骨关节炎的作用靶点。利用 H&E 染色法评估了天麻素对 OA 滑膜组织中性粒细胞浸润和炎性细胞因子的影响。炎性细胞因子的水平通过 ELISA 和 Q-PCR 进行测定。使用 Western 印迹法检测了细胞外基质降解相关蛋白和 PI3K/AKT/FoxO1 信号通路。生物信息学分析预测，天麻素抗OA的靶点可能作用于FoxO通路。通过H&E染色观察到，使用天麻素后，大鼠滑膜组织中的中性粒细胞浸润明显减少。此外，研究还发现天麻素能减轻 IL-1β 诱导的对软骨细胞活力、促炎细胞因子产生和细胞外基质降解的抑制作用。这种效应可归因于天麻素对 PI3K/AKT/FoxO1 的抑制。这些研究结果表明，天麻素可以治疗 OA。

Extracts of Chenopodium hybridum L. leaves and stems exerted a significant antiproliferative effect on human A2780 ovarian cancer cells, but C. hybridum active components have not been reported. Here, a method is described for screening of C. hybridum extracts for potential bioactive components that inhibit A2780 cell proliferation. First, the spectrum–effect relationship between UPLC-Q-Exactive MS chromatograms and C. hybridum extract antiproliferative effect against A2780 cells was established to evaluate extract bioactive components using partial least squares (PLS) analysis. The results indicated that the optimal reflux extraction process for preparing C. hybridum extracts with antiproliferative activity involved a suspension of C. hybridum material in 8 volumes of 70% ethanol followed by heating and refluxing twice for 60 min/reflux step and then repeating the extraction and pooling of both the extracts. Chromatographic results revealed five compounds with potential anti-ovarian cancer activities based on inhibition of A2780 cell proliferation: isorhamnetin-3-O-β-D-furanosyl(1↓2)-O-[α-L-rhamnpyranosyl(1↓6)]-β-D-glucopyranoside, kaempferol-3-O-β-D-glucopyranoside-7-O-α-L-pyranoside, kaempferol-3-O-[α-L-rhamnopyranosyl(1″↓2″)]-β-D-galactopyranoside, quercetin-3,7-di-rhamnose, and isorhamnetin-3-acacia disaccharide. Network pharmacological screening revealed nine core cellular targets that potentially interacted with these compounds. These results were verified through molecular docking studies that supported the involvement of these compounds in observed C. hybridum A2780 cell antiproliferative effects, thus indicating C. hybridum active components may have value in ovarian cancer treatments.

Background Previous research has highlighted the regulatory role of miR-182-5p in targeting TLR4 during the pathogenesis of allergic rhinitis. In a different context, TLR4 has been identified as a crucial factor in the development of lung ischemia-reperfusion injury, where its upregulation is believed to initiate the injury process. Additionally, miR-199a-3p has been shown to possess cardioprotective properties in simulated ischemia/reperfusion (I/R) injury models. Materials and Methods HE and TUNEL were performed to evaluate the cardiac injury and cellular apoptosis of I/R mice under distinct conditions. Real-time PCR was used to analyze the expression of microRNAs (miRNAs) and mRNAs under differential conditions. Results Pretreatment by Shexiang Tongxin Dropping (SXTXD) has been shown to significantly augment the therapeutic efficacy of MSC-derived exosomes (MSC-EXOs) in attenuating cardiac injury in I/R mice. MSC-EXOs effectively restored the repressed miR-182/miR-199a-3p expressions and activated TLR4/CD44 expressions in I/R mice, while SXTXD pretreatment remarkably strengthened the efficiency of MSC-EXOs. Moreover, SXTXD pretreatment notably reinforced the capability of MSC-EXOs to maintain cardiac parameters, including iNOS and interleukin-1β (IL-1β). Furthermore, the luciferase assay indicated that miR-182-5p and miR-199a-3p effectively suppressed the luciferase activities of TLR4 and CD44, respectively, through binding to the 3´ UTR. The overexpression of miR-182-5p and miR-199a-3p significantly suppressed the expression of TLR4 and CD44 in H2C6 and RAW264.7 cells. Conclusion In conclusion, our investigation indicates that MSC-derived exosomes, pretreated with SXTXD, hold promise in mitigating cardiac I/R injury by modulating inflammatory responses through the miR-182-5p/TLR4 axis and miR-199a-3p/CD44 axis. These findings suggest potential therapeutic strategies for addressing I/R-related cardiac complications.

Background Adverse effects of benzene (BZ) exposure toxicities were documented by many researchers worldwide. BZ exposure causes many hematological abnormalities that might be treated with naturally occurring phytocompounds. Aim In this experimental study, we evaluated the anti-inflammatory effect of L-carvone and thymoquinone together (LCTQ) against BZ-induced inflammatory toxicities in Sprague-Dawley (SD) rats. Introduction BZ exposure could cause an excess formation of immature blood cells to enter the peripheral bloodstream. Phytocompounds namely L-carvone (LC) and thymoquinone (TQ) have confirmed anti-inflammatory effects against various diseases. Materials and Methods Rats were divided into four different groups such as control, LCTQ group, BZ pathologic group, and treatment group (LCTQ+BZ). After 10 weeks of the experimental period, body weight changes, hematological parameters, pro-inflammatory cytokines, oxidative stress, RBC antioxidants, bone marrow cellular abnormalities, and bone marrow DNA fragmentation were evaluated. Results BZ toxicity showed abnormal loss of body weight, altered hematological parameters, increased pro-inflammatory cytokines, abnormal cellular oxidative status, and DNA damage. LCTQ treatment showed significant ( p < 0.05) increase in body weight, normalized hematological parameters such as red blood cells, hemoglobin, white blood cells (lymphocytes and eosinophils), platelets (PLT), and hematocrit with RBC parameters, reduction of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6), controlled oxidative stress, normalized enzymatic antioxidants in the RBC cells, normalized nucleated cells, megakaryocyte cells, and controlled DNA fragmentation were observed. Conclusion The current study showed an anti-inflammatory effect of LCTQ through the control of inflammation against benzene-induced toxicities in rats.

Background Insulin resistance (IR) is a pathological state closely associated with various diseases, with hepatic insulin resistance playing a pivotal role. Insulin resistance can be improved by Ginsenoside Rg1 (GRg1), which is known as one of the most biologically active compounds found in ginseng. Nevertheless, the precise role and mechanisms of GRg1 in ameliorating hepatic insulin resistance are still unknown. Objectives We wanted to demonstrate the impact of GRg1 on hepatic insulin resistance and explore the underlying mechanisms in our work. Materials and Methods We mimicked insulin resistance conditions by culturing HepG2 cells in 30 mM glucose for 24 h. The effects of GRg1 on cellular glucose consumption and the key kinases of the phosphatidylinositol-3-kinase (PI3K)/protein kinase B (AKT)/glycogen synthase kinase-3β (GSK-3β) pathway were evaluated. To assess if the PI3K/AKT/GSK-3β pathway is crucial for GRg1’s protective effect against insulin resistance, the compound LY294002, which inhibits PI3K, was employed. Results In HepG2 cells, GRg1 markedly increased glucose uptake while exhibiting no cytotoxicity. Additionally, GRg1 activated the PI3K/AKT/GSK-3β pathway, as indicated by the increased phosphorylation of insulin receptor substrates-1 (IRS-1), AKT, and GSK-3β. Treatment with LY294002 significantly reversed the promotive effects of GRg1 on cellular glucose consumption and PI3K/AKT/GSK-3β pathway activation. Conclusion Taken together, our present study revealed GRg1 exerted a protective effect against hepatic insulin resistance induced by high glucose through PI3K/AKT/GSK-3β pathway, suggesting its potential as a beneficial therapeutic medication.
