    Jiawei Xinglou Chengqi Granule (JXCG) is an effective herbal medicine for the treatment of ischemic stroke (IS). JXCG has been shown to effectively ameliorate cerebral ischemic symptoms in clinical practice, but the underlying mechanisms are unclear. In this study, we investigated the mechanisms of action of JXCG in the treatment of IS by combining metabolomics with network pharmacology. The chemical composition of JXCG was analyzed using ultra-high performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS). Ultra-high performance liquid chromatography-tandem time-of-flight mass spectrometry (UHPLC-Q-TOF MS) untargeted metabolomics were used to identify differential metabolites within metabolic pathways. Network pharmacology was applied to mine potential targets of JXCG in the treatment of IS. The identified key targets were validated by constructing an integrated network of metabolomics and network pharmacology and by molecular docking using Cytoscape. The effect of JXCG on IS was evaluated in vivo, and the predicted targets and pathways of JXCG in IS therapy were assessed using immunoblotting. Combining metabolomics and network pharmacology, we identified the therapeutic targets of JXCG for IS. Notably, JXCG lessened neuronal damage and reduced cerebral infarct size in rats with IS. Western blot analysis showed that JXCG upregulated PRKCH and downregulated PRKCE and PRKCQ proteins. Our combined network pharmacology and metabolomics findings showed that JXCG may have therapeutic potential in the treatment of IS by targeting multiple factors and pathways.

    UNASSIGNED: To explored the potential molecular mechanism of Sugemule-4 decoction (MMS-4D) in treating insomnia.
    UNASSIGNED: DL-4-chlorophenylalanine (PCPA) + chronic unpredictable mild stress stimulation (CUMS) was used to induce an insomnia model in rats. After the model was successfully established, MMS-4D was intervened at low, medium, and high doses for 7 days. The open-field test (OFT) was used to preliminarily evaluate the efficacy. The potential mechanism of MMS-4D in treating insomnia was investigated using gut microbiota, serum metabolomics, and network pharmacology (NP). Experimental validation of the main components of the key pathways was carried out using ELISA and Western blot.
    UNASSIGNED: The weights of the insomnia-model rats were significantly raised (p ≤ 0.05), the total exercise distance in the OFT increased (p ≤ 0.05), the rest time shortened, and the number of standing times increased (p ≤ 0.05), after treatment with MMS-4D. Moreover, there was a substantial recovery in the 5-HT, DA, GABA, and Glu levels in the hypothalamus tissue and the 5-HT and GABA levels in the colon tissue of rats. The expression of DAT and DRD1 proteins in the hippocampus of insomnia rats reduced after drug treatment. MMS-4D may treat insomnia by regulating different crucial pathways including 5-HT -, DA -, GABA -, and Glu-mediated neuroactive light receiver interaction, cAMP signaling pathway, serotonergic, glutamatergic, dopaminergic, and GABAergic synapses.
    UNASSIGNED: This study revealed that MMS-4D can improve the general state and behavioral changes of insomnia model rats. Its mechanism may be related to the reversal of abnormal pathways mediated by 5-HT, DA, GABA, and Glu, such as Serotonergic synapse, Dopaminergic synapse, Glutamatergic synapse, and GABAergic synapse.

    脊髓损伤(SCI)是脊柱手术中的严重创伤性疾病,其特征是受伤区域及其下方的神经损伤。尽管在理解SCI的病理生理学方面取得了进展,但有效的临床治疗仍然难以捉摸。硒化合物因其具有多样化的药用活性而成为研究热点。以前,我们小组合成了具有显著抗炎活性的含硒化合物34#。本研究旨在通过网络药理学探讨含硒化合物的抗SCI作用,分子对接(MD),和ADMET方法。为了识别SCI相关目标和与34#相关的目标,GeneCards,NCBI,并采用了SEA数据库。八个重叠目标被视为候选目标,使用PDB数据库和AutoDock软件进行分子对接。STRING数据库用于获得蛋白质-蛋白质相互作用(PPI)。分子动力学模拟,MM/GBSA结合自由能评分,和ADMET预测用于评估34#的潜在靶标和药物性质。最后,在NSC34细胞和小鼠实验中验证34#对SCI的影响。我们的结果揭示了SCI治疗中34#的八个候选目标。PPI和MD将ADRB2和HTR1F确定为34#的最高连通性。ADMET剖析证实了34#的低毒性和平安性。体外和体内模型验证了抗SCI作用。我们的研究阐明了34#减轻SCI的候选目标,探索PPI和靶标相关信号通路,并验证了其抗SCI效果。这些发现增强了我们对34#SCI治疗机制的理解,将其定位为SCI预防的潜在候选者。
    Spinal cord injury (SCI) is a severe traumatic condition in spinal surgery characterized by nerve damage in and below the injured area. Despite advancements in understanding the pathophysiology of SCI, effective clinical treatments remain elusive. Selenium compounds have become a research hotspot due to their diverse medicinal activities. Previously, our group synthesized a selenium-containing Compound 34# with significant anti-inflammatory activity. This study aimed to explore the anti-SCI effects of selenium-containing compounds using network pharmacology, molecular docking (MD), and ADMET methods. To identify SCI-related targets and those associated with 34#, GeneCards, NCBI, and SEA databases were employed. Eight overlapping targets were considered candidate targets, and molecular docking was performed using the PDB database and AutoDock software. The STRING database was used to obtain protein-protein interactions (PPI). Molecular dynamics simulation, MM/GBSA binding free energy score, and ADMET prediction were used to evaluate the potential targets and drug properties of 34#. Finally, experiments on NSC34 cells and mice were to verify the effects of 34# on SCI. Our results revealed eight candidate targets for 34# in the treatment of SCI. PPI and MD identified ADRB2 and HTR1F as the highest connectivity with 34#. ADMET analysis confirmed the low toxicity and safety of 34#. In vitro and in vivo models validated the anti-SCI effects. Our study elucidated candidate targets for alleviating SCI with 34#, explored PPI and target-related signaling pathways, and validated its anti-SCI effects. These findings enhance our understanding of 34#\'s mechanism in treating SCI, positioning it as a potential candidate for SCI prevention.

    基于分泌型卷曲相关蛋白2(SFRP2)-Wnt/β-catenin信号通路,本研究探讨了古鲁颗粒(CRKL)治疗产后无乳的疗效及作用机制。
    通过在分娩后第3天向雌性大鼠灌胃2mL的1.6mg/mL甲磺酸溴隐亭来建立产后缺乳的大鼠模型。选取分娩时间差小于48小时的雌性大鼠,随机分为7组,包括正常组(没有任何建模或药物治疗),一个模型组,CRKL低剂量组模型组大鼠接受3g/kg剂量的CRKL,CRKL中剂量组模型大鼠接受6g/kg剂量的CRKL,CRKL高剂量组模型大鼠接受9g/kg剂量的CRKL,阳性药物组的模型大鼠接受剂量为3mg/kg的多潘立酮,和接受生理盐水的模型大鼠的阴性对照(NC)组。每组6只大鼠。除正常组和模型组外,其余5组通过每天一次管饲法连续给予指定剂量的相应干预药物,共10天.测量了7组10天内后代总凋落物质量的变化,并进行HE染色以鉴定乳腺组织(MT)的病理变化。6组大鼠(排除阳性对照组)观察垂体组织嗜酸性粒细胞的病理变化。ELISA法测定血清中催乳素(PRL)含量,免疫组化染色检测MT中催乳素受体(PRLR)的表达,采用RT-qPCR检测MT泌乳相关基因的mRNA表达。采用网络药理学和分子对接技术研究CRKL对产后无乳的治疗作用及机制,特别是它是否通过SFRP2-Wnt/β-catenin信号通路起作用。通过检测相关通路基因的mRNA(RT-qPCR)和蛋白表达(Westernblot)进一步验证CRKL治疗的机制。使用来自大鼠MT的原代培养大鼠乳腺上皮细胞(RMEC)进行细胞实验。RMEC分为四组,包括一个正常组(原代培养RMEC,未经处理),SFRP2过表达组(用SFRP2过表达载体处理的原代培养RMEC),SFRP2过表达+CRKL组(接受SFRP2过表达组加10%含药血清治疗),和阴性对照组(用空载体处理的原代培养RMEC)。CRKL对泌乳相关基因FASN表达的影响,通过RT-qPCR检测SFRP2过表达后的CSN2和GLUT1mRNA。
    在这项研究中,CRKL低剂量组给药剂量为3g/kg,中剂量组6g/kg,高剂量组9g/kg(P<0.05或P<0.01)。与模型组相比,CRKL在所有剂量下均显着增加了10天内后代的总增重(P<0.05或P<0.01)。并有效增加泌乳(P<0.01),乳腺小叶区域,以及腺泡腔的大小和填充。在所有剂量的CRKL也增加了分泌PRL的嗜酸性粒细胞的数量在产后缺乳大鼠模型的垂体,并增加血清中PRL的含量(P<0.05或P<0.01)。CRKL促进产后缺气模型大鼠PRL的分泌和表达。此外,显著促进乳脂相关基因的表达,牛奶蛋白,和MT中乳糖合成(P<0.05或P<0.01)。网络药理学预测Wnt信号通路可能是CRKL治疗产后无乳的关键通路。分子对接结果表明,CRKL中的相关化学成分与CCND1和SFRP2具有良好的结合能力。与模型组相比,所有剂量的CRKL均能在体内抑制SFRP2基因的表达(P<0.01),并激活MT中Wnt/β-catenin信号通路中CCND1和c-Myc的mRNA和蛋白表达(P<0.05或P<0.01)。细胞实验表明,与正常组相比,SFRP2过表达降低乳合成相关基因FASN的mRNA表达,CSN2和GLUT1在RMEC中表达(P<0.01)。CCK8结果表明,含药血清的10%是对细胞给药的有效浓度(P<0.01)。服用含药血清后,泌乳相关基因FASN的表达,CSN2和GLUT1上调(与SFRP2过表达组相比,P<0.01)。
    CRKL通过SFRP2-Wnt/β-catenin信号通路缓解产后无乳。SFRP2可能成为产后无乳诊断和治疗的潜在新靶点。这揭示了CRKL治疗产后缺乳的新机制,促进了其临床应用。
    UNASSIGNED: Based on the secreted frizzled-related protein 2 (SFRP2)-Wnt/β-catenin signaling pathway, this study explored the effect and mechanism of Cuiru Keli (CRKL) in the treatment of postpartum hypogalactia.
    UNASSIGNED: A rat model of postpartum hypogalactia was established by gavaging 2 mL of 1.6 mg/mL bromocriptine mesylate to female rats on the third day after delivery. Female rats with a delivery time difference of less than 48 hours were selected and randomly assigned to 7 groups, including a normal group (without any modeling or medication), a model group, a CRKL low-dose group of model group model rats receiving CRKL at the dose of 3 g/kg, a CRKL medium-dose group of model rats receiving CRKL at the dose of 6 g/kg, a CRKL high-dose group of model rats receiving CRKL at the dose of 9 g/kg, a positive drug group of model rats receiving domperidone at the dose of 3 mg/kg, and a negative control (NC) group of model rats receiving normal saline. Each group contained 6 rats. Except for the normal and model groups, the remaining 5 groups were continuously administered with the respective intervention drugs at the specified doses by gavage once a day for 10 days. Changes in the total litter mass of the offspring in the 7 groups within 10 days were measured, and HE staining was performed to identify pathological changes in the mammary tissue (MT). Six groups of rats (excluding the positive control group) were used to observe the pathological changes of eosinophils in pituitary tissue. ELISA was performed to determine the content of prolactin (PRL) in serum, immunohistochemical staining was used to determine the expression of prolactin receptor (PRLR) in MT, and RT-qPCR was used to determine the mRNA expression of genes related to lactation in MT. Network pharmacology and molecular docking were used to study the therapeutic effect and mechanism of CRKL on postpartum hypogalactia, particularly whether it acted through the SFRP2-Wnt/β-catenin signaling pathway. The mechanism of CRKL treatment was further validated by detecting mRNA (RT-qPCR) and protein expression (Western blot) of related pathway genes. Cell experiments were conducted using primary culture rat mammary epithelial cells (RMEC) from rat MT. RMEC were divided into four groups, including a normal group (primary culture RMEC, untreated), SFRP2 overexpression group (primary cultured RMEC treated with SFRP2 overexpression vector), SFRP2 overexpression+CRKL group (receiving treatment for SFRP2 overexpression group plus 10% drug-containing serum), and negative control group (primary culture RMEC treated with empty vector). The effect of CRKL on the expression of lactation-related genes FASN, CSN2, and GLUT1 mRNA after SFRP2 overexpression was detected by RT-qPCR.
    UNASSIGNED: In this study, CRKL was administered at a dose of 3 g/kg in the CRKL low-dose group, 6 g/kg in the medium-dose group, and 9 g/kg in the high-dose group (P<0.05 or P<0.01). Compared with the model group, CRKL at all doses significantly increased the total litter weight gain of the offsprings within 10 days (P<0.05 or P<0.01), and effectively increased lactation (P<0.01), the area of mammary lobules, and the size and filling of acinar cavities. CRKL at all doses also increased the number of eosinophils that secreted PRL in the pituitary gland of the postpartum hypogalactia rat model, and increased the content of PRL in the serum (P<0.05 or P<0.01). CRKL promoted the secretion and expression of PRL in postpartum hypogalactic model rats. In addition, it significantly promoted the expression of genes related to milk fat, milk protein, and lactose synthesis in MT (P<0.05 or P<0.01). Network pharmacology predicted that the Wnt signaling pathway might be a key pathway for CRKL in treating postpartum hypogalactia. The molecular docking results showed that related chemical components in CRKL had good binding ability with CCND1 and SFRP2. Compared with the model group, CRKL at all doses inhibited the expression of SFRP2 gene in vivo (P<0.01) and activated the mRNA and protein expression of CCND1 and c-Myc in the Wnt/β-catenin signaling pathway in MT (P<0.05 or P<0.01). Cell experiments showed that, compared to the normal group, SFRP2 overexpression reduced the mRNA expression of milk synthesis-related genes FASN, CSN2, and GLUT1 in RMEC (P<0.01). The CCK8 results indicated that 10% of the drug-containing serum was the effective concentration administered to cells (P<0.01). After administering drug-containing serum, the expression of the lactation-related genes FASN, CSN2, and GLUT1 were up-regulated (compared with the SFRP2 overexpression group, P<0.01).
    UNASSIGNED: CRKL alleviates postpartum hypogalactia through the SFRP2-Wnt/β-catenin signaling pathway. SFRP2 might be a potential new target for the diagnosis and treatment of postpartum hypogalactia. This reveals a new mechanism of CRKL in treating postpartum hypogalactia and promotes its clinical application.

    Microglia are resident immune cells in the central nervous system that are rapidly activated to mediate neuroinflammation and apoptosis, thereby aggravating brain tissue damage after ischemic stroke (IS). Although scutellarin has a specific therapeutic effect on IS, the potential target mechanism of its treatment has not been fully elucidated. In this study, we explored the potential mechanism of scutellarin in treating IS using network pharmacology. Lipopolysaccharide (LPS) was used to induce an in vitro BV-2 microglial cell model, while middle cerebral artery occlusion (MCAO) was used to induce an in vivo animal model. Our findings indicated that scutellarin promoted the recovery of cerebral blood flow in MCAO rats at 3 days, significantly different from that in the MCAO group. Western blotting and immunofluorescence revealed that scutellarin treatment of BV-2 microglial cells resulted in a significant reduction in the protein expression levels and incidence of cells immunopositive for p-NF-κB, TNF-α, IL-1β, Bax, and C-caspase-3. In contrast, the expression levels of p-PI3K, p-AKT, p-GSK3β, and Bcl-2 were further increased, significantly different from those in the LPS group. The PI3K inhibitor LY294002 had similar effects to scutellarin by inhibiting neuroinflammation and apoptosis in activated microglia. The results of the PI3K/AKT/GSK3β signaling pathway and NF-κB pathway in vivo in MCAO models induced microglia at 3 days were consistent with those obtained from in vitro cells. These findings indicate that scutellarin plays a neuroprotective role by reducing microglial neuroinflammation and apoptosis mediated by the activated PI3K/AKT/GSK3β/NF-κB signaling pathway.

    BACKGROUND: CDD-2103 is an herbal prescription used to treat ulcerative colitis (UC). This study aimed to uncover its mechanism by integrating metabolomics and serum-feces pharmacochemistry-based network pharmacology.
    METHODS: A DSS-induced chronic colitis mice model was used to evaluate the anti-colitis effect of CDD-2103. Serum and feces metabolomics were conducted to identify differential metabolites and pathways. In the serum-feces pharmacochemistry study, biological samples were collected from rats treated with CDD-2103. Then, network pharmacology was utilized to predict the targets of the identified compounds. Critical genes were extracted through the above-integrated analysis. The interactions between targets, CDD-2103, and its compounds were validated through molecular docking, immunoblotting, and enzyme activity assays.
    RESULTS: CDD-2103 alleviated ulcerous symptoms and colonic injuries in colitis mice. Metabolomics study identified differential metabolites associated with tryptophan, glycerophospholipid, and linoleic acid metabolisms. The serum-feces pharmacochemistry study revealed twenty-three compounds, which were subjected to network pharmacology analysis. Integration of these results identified three key targets (AHR, PLA2, and PTGS2). Molecular docking showed strong affinities between the compounds and targets. PTGS2 was identified as a hub gene targeted by most CDD-2103 compounds. Immunoblotting and enzyme activity assays provided further evidence that CDD-2103 alleviates UC, potentially through its inhibitory effect on cyclooxygenase-2 (COX-2, encoded by PTGS2), with alkaloids and curcuminoids speculated as crucial anti-inflammatory compounds.
    CONCLUSIONS: This integrated strategy reveals the mechanism of CDD-2103 and provides insights for developing herbal medicine-based therapies for UC.

    慢性萎缩性胃炎(CAG),以胃壁发炎和糜烂为特征,是一种普遍的消化系统疾病,被认为是胃癌(GC)的前兆。法国黄连(CCF)以其有效的清热而闻名,排毒,和抗炎特性。左金丸(ZJP),主要由CCF组成的经典中药,已证明在CAG治疗中有效。本研究旨在通过包括网络药理学在内的多方面方法阐明CCF治疗CAG的潜在机制。分子对接,分子动力学模拟和实验验证。该研究确定了CCF的三种主要活性化合物,并阐明了关键途径,如TNF信号,PI3K-Akt信号和p53信号。分子对接揭示了这些活性化合物与关键靶标如PTGS2,TNF,MTOR,TP53。此外,分子动力学模拟验证了小檗碱是CCF的主要活性化合物,通过实验验证进一步证实了这一点。这项研究不仅确定了小檗碱是CCF的主要活性化合物,而且为CCF治疗CAG的潜在分子机制提供了有价值的见解。此外,为完善CAG管理的治疗策略提供参考。
    Chronic atrophic gastritis (CAG), characterized by inflammation and erosion of the gastric lining, is a prevalent digestive disorder and considered a precursor to gastric cancer (GC). Coptis chinensis France (CCF) is renowned for its potent heat-clearing, detoxification, and anti-inflammatory properties. Zuojin Pill (ZJP), a classic Chinese medicine primarily composed of CCF, has demonstrated effectiveness in CAG treatment. This study aims to elucidate the potential mechanism of CCF treatment for CAG through a multifaceted approach encompassing network pharmacology, molecular docking, molecular dynamics simulation and experimental verification. The study identified three major active compounds of CCF and elucidated key pathways, such as TNF signaling, PI3K-Akt signaling and p53 signaling. Molecular docking revealed interactions between these active compounds and pivotal targets like PTGS2, TNF, MTOR, and TP53. Additionally, molecular dynamics simulation validated berberine as the primary active compound of CCF, which was further confirmed through experimental verification. This study not only identified berberine as the primary active compound of CCF but also provided valuable insights into the molecular mechanisms underlying CCF\'s efficacy in treating CAG. Furthermore, it offers a reference for refining therapeutic strategies for CAG management.
