Effects of a Combined Chinese Herbal Medicine on Growth Performance, Intestinal Barrier Function, Immune Response, and Cecal Microflora in Broilers Infected with Salmonella enteritidis.

This study investigated the effects of CCHM in drinking water on broilers infected with Salmonella enteritidis. One-day-old male Cobb 500 broilers (n = 300) were randomly assigned to five groups: a control (NC) group, a Salmonella enteritidis challenge (SE) group, an antibiotic (AB) group, a low dose of CCHM (CL) group, and a high dose of CCHM (CH) group. Each group had six replicate cages with ten broilers per cage. The broilers in the NC and SE groups were given normal drinking water. From days 12 to 18, the AB group received water treated with ciprofloxacin lactate injection (1 mL/L), while the CL and CH groups received water containing CCHM at doses of 5 mL/L and 10 mL/L, respectively. Broilers in all groups except the NC group were orally given Salmonella enteritidis daily from days 9 to 11. The experimental period was 28 days. The results showed that, compared with the SE group, the CL and CH groups showed improved growth performance; increased immune organ indices, expressions of ileal occludin and ZO-1 proteins, jejunal and ileal villus heights (except at day 19), and cecal Lactobacillus counts on days 19 and 28 (p < 0.05); and decreased jejunal and ileal lesion scores, ileal interleukin 1β (IL-1β) (except at day 19), interferon-γ (IFN-γ), interleukin 6 (IL-6) (except at day 19), secretory immunoglobulin A (slgA) and tumor necrosis factor α (TNF-α) (except at day 19) levels, serum D-lactic acid and diamine oxidase (DAO) (except at day 19) contents, jejunal and ileal crypt depths (except at day 19), and cecal Salmonella and Escherichia coli counts on days 19 and 28 (p < 0.05). On day 28, except for the levels of ileal interleukin 10 (IL-10), TNF-α, slgA, and serum D-lactic acid content, there were no differences among the NC, AB, and CL groups (p > 0.05). In conclusion, drinking water supplemented with CCHM alleviated the intestinal damage caused by Salmonella enteritidis infection and improved growth performance and cecal microbiota in broilers. The optimal addition rate of CCHM was 5 mL/L.

Wogonin induces mitochondrial apoptosis and synergizes with venetoclax in diffuse large B-cell lymphoma

Diffuse large B-cell lymphoma (DLBCL) is among the most aggressive hematological malignancies and patients are commonly treated with combinatorial immunochemotherapies such as R-CHOP. Till now, the prognoses are still variable and unsatisfactory, depending on the molecular subtype and the treatment response. Developing effective and tolerable new agents is always urgently needed, and compounds from a natural source have gained increasing attentions. Wogonin is an active flavonoid extracted from the traditional Chinese herbal medicine Scutellaria baicalensis Georgi and has shown extensive antitumor potentials. However, the therapeutic effect of wogonin on DLBCL remains unknown. Here, we found that treatment with wogonin dose- and time-dependently reduced the viability in a panel of established DLBCL cell lines. The cytotoxicity of wogonin was mediated through apoptosis induction, along with the loss of mitochondrial membrane potential and the downregulation of BCL-2, MCL-1, and BCL-xL. In terms of the mechanism, wogonin inhibited the PI3K and MAPK pathways, as evidenced by the clear decline in the phosphorylation of AKT, GSK3β, S6, ERK, and P38. Furthermore, the combination of wogonin and the BCL-2 inhibitor venetoclax elicited synergistically enhanced killing effect on DLBCL cells regardless of their molecular subtypes. Finally, administration of wogonin significantly impeded the progression of the DLBCL tumor in a xenograft animal model without obvious side effects. Taken together, the present study suggests a promising potential of wogonin in the treatment of DLBCL patients either as monotherapy or an adjuvant for venetoclax-based combinations.

Patient-Reported Outcomes of Postoperative NSCLC Patients with or without Staged Chinese Herb Medicine Therapy during Adjuvant Chemotherapy (NALLC 2): A Randomized, Double-Blind, Placebo-Controlled Trial.

To investigate whether the combination of chemotherapy with staged Chinese herbal medicine (CHM) therapy could enhance health-related quality of life (QoL) in non-small-cell lung cancer (NSCLC) patients and prolong the time before deterioration of lung cancer symptoms, in comparison to chemotherapy alone. A prospective, double-blind, randomized, controlled trial was conducted from December 14, 2017 to August 28, 2020. A total of 180 patients with stage I B-IIIA NSCLC from 5 hospitals in Shanghai were randomly divided into chemotherapy combined with CHM (chemo+CHM) group (120 cases) or chemotherapy combined with placebo (chemo+placebo) group (60 cases) using stratified blocking randomization. The European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life-Core 30 Scale (QLQ-C30) was used to evaluate the patient-reported outcomes (PROs) during postoperative adjuvant chemotherapy in patients with early-stage NSCLC. Adverse events (AEs) were assessed in the safety analysis. Out of the total 180 patients, 173 patients (116 in the chemo+CHM group and 57 in the chemo+placebo group) were included in the PRO analyses. The initial mean QLQ-C30 Global Health Status (GHS)/QoL scores at baseline were 57.16 ± 1.64 and 57.67 ± 2.25 for the two respective groups (P>0.05). Compared with baseline, the chemo+CHM group had an improvement in EORTC QLQ-C30 GHS/QoL score at week 18 [least squares mean (LSM) change 17.83, 95% confidence interval (CI) 14.29 to 21.38]. Conversely, the chemo+placebo group had a decrease in the score (LSM change -13.67, 95% CI -22.70 to -4.63). A significant between-group difference in the LSM GHS/QoL score was observed, amounting to 31.63 points (95% CI 25.61 to 37.64, P<0.001). The similar trends were observed in physical functioning, fatigue and appetite loss. At week 18, patients in the chemo+CHM group had a higher proportion of improvement or stabilization in GHS/QoL functional and symptom scores compared to chemo+placebo group (P<0.001). The median time to deterioration was longer in the chemo+CHM group for GHS/QoL score [hazard ratio (HR)=0.33, 95% CI 0.23 to 0.48, P<0.0010], physical functioning (HR=0.43, 95% CI 0.25 to 0.75, P=0.0005), fatigue (HR=0.47, 95% CI 0.30 to 0.72, P<0.0001) and appetite loss (HR=0.65, 95% CI 0.42 to 1.00, P=0.0215). The incidence of AEs was lower in the chemo+CHM group than in the chemo+placebo group (9.83% vs. 15.79%, P=0.52). The staged CHM therapy could help improve the PROs of postoperative patients with early-stage NSCLC during adjuvant chemotherapy, which is worthy of further clinical research.

Periostracum Cicadae exhibits immunosuppressive effects on dendritic cells and contact hypersensitivity responses

Ethnopharmacological relevancePeriostracum Cicadae (PC), the molted exoskeleton of the cicada Cryptotympana pustulata Fabricius, is frequently employed in Chinese herbal medicine. Based on traditional therapies and pharmacological studies, PC appears to have immunomodulatory activity. However, the specific impact of PC on immunomodulation, particularly its effect on dendritic cells (DCs), remains unknown. DCs act professionally as antigen-presenting cells that trigger adaptive immune responses, making them critical for immunomodulation. Materials and methodsThe DCs derived from mouse bone marrow were used to examine the suppressive effect of PC extract on DC activation and maturation. The in vivo suppressive effect was evaluated using a mouse model of contact hypersensitivity (CHS) responses. The determination of the substances in the sample was performed by Liquid chromatography-mass spectrometry/mass spectrometry. ResultsThe ethyl acetate extract of PC (PCEA) significantly decreased the expressions of proinflammatory cytokines (IL-12, interleukin [IL]-6, as well as tumor necrosis factor [TNF]-α) and surface markers CD80 and CD86 in lipopolysaccharide-stimulated DCs. In the 2,4-dinitro-1-fluorobenzene-induced CHS mouse model, PCEA treatment dramatically attenuated the severity of symptoms. This was evidenced by the alleviation of ear swelling and a reduction in the count of infiltrating CD3+ T cells in the tested ears. In addition, N-acetyldopamine dimer and trimer were identified as major components. ConclusionThis study is the first to show that components derived from PCEA inhibit the activation and maturation of DCs as well as CHS responses, indicating they have the potential for treating delayed-type hypersensitivity or DC-related immune disorders.

A systematic review on anticancer potential of traditional Chinese medicine (Yang Zheng XiaoJi)

BackgroundThe term "cancer" refers to illnesses in which cells can proliferate uncontrollably, infiltrate, and spread to various body organs. Since it has been used for thousands of years, traditional Chinese medicine (TCM) is now commonly regarded as an alternative for treating cancer. It has been demonstrated that Yangzheng Xiaoji (YX), a traditional Chinese medicine formulation, has anticancer effects in patients with different tumor types. MethodSearches were conducted in several electronic databases from the year 2003 to 2024, including Pubmed, Google Scholar, Scopus, and Science Direct, to find evidence about YX. The purpose of this review is to provide an overview of YX's anticancer research findings. ResultA result of the limited understanding of the fundamental mechanisms of action of the herbs, modern medicine frequently conflicts with traditional medicine, such as Chinese herbal medicine. Our research demonstrates the broad spectrum of anticancer potential of the YX formulation. Additionally, the particular YX component was also searched for anticancer potential. DiscussionWe have chosen to emphasize only some aspects of each YX ingredient's function in cancer therapy because it has been suggested that several processes are involved when applying TCM therapies. Furthermore, the effect of YX therapy on various malignancies is also covered. Additionally, we have emphasized YX treatment research that alters the tumor microenvironment and eradicates cancer. ConclusionThe data gathered in this review will act as a strong basis for creating YX for cancer therapy.

Progress in the Study of Chemical Structure and Pharmacological Effects of Total Paeony Glycosides Isolated from Radix Paeoniae Rubra.

Radix paeoniae rubra, known as red peony root, is derived from the dried roots of Paeonia lactiflora pall or Paeonia veitchii lynch from the Ranunculaceae family. It is recognized for its properties of clearing heat, cooling blood, dispelling stasis, and alleviating pain, making it one of the most commonly used herbs in traditional Chinese medicine. Total paeony glycosides (TPGs) are identified as the principal active constituents of Radix paeoniae rubra, comprising monoterpenoid compounds with a cage-like pinane structure and monoterpenoids with a lactone structure. This review summarizes the chemical constituents and pharmacological effects of TPGs, with the aim of elucidating their relationships.

Dynamic changes in the metabolome and microbiome during Citrus depressa Hayata liquid fermentation

Citri Reticulatae Pericarpium (CRP) is a common traditional Chinese herbal medicine, valued for its multi-bioactivity. However, its processing time, environment, and microorganisms all affect its quality and bioactivity. To address this, the study replaced solid-state fermentation with liquid fermentation using microorganisms and isolated Bacillus amyloliquefaciens, respectively. This aimed to discover a more stable processing method and examine metabolite-micobiota correlations. Non-targeted metabolomics identified 70 differential metabolites, focusing on amino acids, polymethoxyflavones (PMFs), and carbohydrates. Long-read sequencing showed a shift in dominant bacterial genera from Lactobacillus to Pediococcus, then to Clostridium. Spearman analysis revealed a positive correlation between specific Clostridium species and PMFs production. B. amyloliquefaciens fermentation notably increased PMFs content without reducing hesperidin levels, suggesting its potential as an alternative processing method. This study offers valuable insights into metabolome-microbiome interactions for future biotransformation research.

Angelica sinensis polysaccharides ameliorate 5-FU-induced stress anemia via promoting extramedullary erythroblastic island central macrophage-mediated erythroid differentiation

BackgroundChronic anemia, especially chemotherapy-induced anemia, is a common and intractable symptom. Puzzlingly, the conventional anemic treatment may lead to various side effects, and the mechanism of stress anemia remains unclear. MethodsHere, peripheral blood, histopathological and transmission electron microscopical examination, colony forming test, flow cytometry, and qRT-PCR assay were used to investigate the effects of Angelia sinensis polysaccharide (ASP), one main active ingredient of Chinese herb medicine Angelica sinensis, on ameliorating 5-fluorouracil (5-FU)-induced stress anemia. ResultsWe found that intraperitoneal injection to a C57BL/6J mouse ASP 100 mg/kg per day for consecutive 10 days or 14 days, remarkably accelerated the recovery of RBC, hemoglobin, and hematocrit in blood. ASP alleviated 5-FU-caused impairment of bone marrow cell and BFU-E enumeration. Meanwhile, ASP antagonized 5-FU promoting extramedullary erythropoiesis in the spleen, inducing splenomegaly due to stress erythroblastic islands, and occurrence of megakaryocytes and hematopoietic precursors in splenic colonies. ASP increased splenic stress BFU-E enumeration, driving BFU-E differentiation towards Pro-E and end-stage erythroblasts. Furthermore, ASP increased the number of F4/80+VCAM-1+ splenic erythroblastic island central macrophages, upregulating genetic expression of EPOR, Emp, VCAM-1, Hmox-1, Trf, TfR1, Fpn1, Spi-C, DNase2a, Tim4, MertK, and Klf1 in splenocytes. ConclusionsOur findings indicate that the possible mechanism of chemotherapy-induced anemia is related to stress erythroid maturation arrest. Whereas, ASP may promote stress erythroid differentiation via elevated EPO sensitivity in extramedullary hematopoietic organs and enhanced macrophage-mediated adhesion, iron homeostasis and transfer, and nuclear engulfment, which may represent a promising therapeutic strategy.

In vivo targeted-imaging of mitochondrial acidification in an aristolochic acid I-induced nephrotoxicity mouse model by a fluorescent/photoacoustic bimodal probe

Aristolochic acid I (AAI), a natural compound in aristolochia type Chinese medicinal herb, is generally acknowledged to have nephrotoxicity, which may be associated with mitophagy. Mitophagy is a cellular process with important functions that drive AAI-induced renal injury. Mitochondrial pH is currently measured by fluorescent probes in cell culture, but existing probes do not allow for in situ imaging of AAI-induced mitophagy in vivo. We developed a ratiometric fluorescent/PA dual-modal probe with a silicon rhodamine fluorophore and a pH-sensitive hemicyanine dye covalently linked via a short chain to obtain a FRET type probe. The probe was used to measure AAI-mediated mitochondrial acidification in live cells and in vivo. The Förster resonance energy transfer (FRET)-mediated ratiometric and bimodal method can efficiently eliminate signal variability associated with the commonly used one-emission and single detection mode by ratiometric two channels of the donor and acceptor. The probe has good water-solubility and low molecular weight with two positively charged, facilitating its precise targeting into renal mitochondria, where the fluorescent/PA changes in response to mitochondrial acidification, enabling dynamic and semi-quantitative mapping of subtle changes in mitochondrial pH in AAI-induced nephrotoxicity mouse model for the first time. Also, the joint use of L-carnitine could mitigate the mitophagy in AAI-induced nephrotoxicity.

Prenylated Flavonoids Isolated from the Root of Sophora flavescens as Potent Antifungal Agents against Botrytis cinerea.

Sophora flavescens, a traditional Chinese herb, produces a wide range of secondary metabolites with a broad spectrum of biological activities. In this study, we isolated six isopentenyl flavonoids (1-6) from the roots of S. flavescens and evaluated their activities against phytopathogenic fungi. In vitro activities showed that kurarinone and sophoraflavanone G displayed broad spectrum and superior activities, among which sophoraflavanone G displayed excellent activity against tested fungi, with EC50 values ranging from 4.76 to 13.94 μg/mL. Notably, kurarinone was easily purified and showed potential activity against Rhizoctonia solani, Botrytis cinerea, and Fusarium graminearum with EC50 values of 16.12, 16.55, and 16.99 μg/mL, respectively. Consequently, we initially investigated the mechanism of kurarinone against B. cinerea. It was found that kurarinone disrupted cell wall components, impaired cell membrane integrity, increased cell membrane permeability, and affected cellular energy metabolism, thereby exerting its effect against B. cinerea. Therefore, kurarinone is expected to be a potential candidate for the development of plant fungicides.

Adjunctive Therapy with Chinese Herbal Medicine Lowers Risk of Hearing Loss in Type 2 Diabetes Patients: Results from a Cohort-Based Case-Control Study.

Hearing loss is a frequently observed complication of type 2 diabetes (T2D). Emerging evidence has found that Chinese herbal medicine (CHM) can effectively treat chronic disease; nevertheless, it is unclear if adding CHM to the routine management of T2D would modify sequent risk of hearing loss. This cohort-based case-control study was conducted to address this issue. First, a total of 64,418 subjects aged 20-70 years, diagnosed with T2D between 2002 and 2011, were extracted from a nationwide health claims database. Among them, we identified 4516 cases of hearing loss after T2D by the end of 2013. They were then randomly matched to 9032 controls without hearing loss at a 1:2 ratio. Following conditional logistic regression, we found the addition of CHM to conventional care reduced the risk of developing hearing loss, with an adjusted odds ratio of 0.75 (95% confidence interval: 0.70-0.83). Specifically, taking CHM products for at least two years benefits T2D patients in lowering sequent risk of hearing loss. The findings herein implicated that integrating CHM into conventional care substantially correlated to lower risk of hearing loss for T2D patients, but further basic research is needed to secure the application of finished herbal products.

Structural damage and organelle destruction: Mechanisms of pseudolaric acid B against S. parasitica

This study aimed to investigate the potential of Chinese herbs in treating aquatic diseases. More particularly, the antibacterial properties and mechanisms of Chinese herbs and their monomers against Saprolegnia parasitica were investigated. In vitro antibacterial testing revealed that Cortex pseudolaricis exhibited significant antibacterial activity, with a minimum inhibitory concentration (MIC) of 0.98 mg/mL. The primary monomer responsible for this antibacterial effect was identified as pseudolaric acid B (PAB), with an MIC of 0.03 mg/mL. SEM and TEM analyses demonstrated that treatment with PAB resulted in structural damage to the cell wall and cell membrane of hyphae, leading to lysis of the cell wall and membrane of spores, organelle destruction, and vacuole formation within the cells. Analysis of the transcriptome and metabolome revealed that PAB disrupts amino acid, lipid, and nucleic acid metabolism in S. parasitica. This disruption impacts the biosynthesis and metabolism of various amino acids, including arginine, proline, glycine, serine, cysteine, methionine, glutamate, lysine, histidine, phenylalanine, tyrosine, and tryptophan. PAB also results in increased energy consumption and hindered energy generation in S. parasitica, as well as interference with the synthesis of membrane components such as DAG and phytosphingosine. Furthermore, PAB disrupts RNA, DNA, and ATP production in S. parasitica. Consequently, protein synthesis, energy supply, immune function and barrier structure in S. parasitica are weakened, and potentially leading to death. This study identifies potential antibacterial agents for environmentally friendly solutions for controlling fish saprolegniasis.

Deciphering the mechanism of Chaihu Shugan San in the treatment of nonalcoholic steatohepatitis using network pharmacology and molecular docking.

In China, there is a long history and rich clinical experience in treating nonalcoholic steatohepatitis (NASH) with traditional Chinese herbal medicines, including Chai Hu Shu Gan San. This study aims to investigate the potential regulatory effects of Chaihu Shugan San (CSS) on liver lipid metabolism and inflammatory damage in mice with experimental nonalcoholic steatohepatitis (NASH) induced by a choline-deficient high-fat diet (CDHFD). Utilizing network pharmacology, we systematically explore the mechanisms of action and therapeutic potential of CSS against NASH. Potential targets in CSS and targets for NASH were identified using online databases. Functional enrichment and protein-protein interaction analyses were conducted to identify hub-targeted genes and elucidate the underlying molecular mechanisms. The affinities of active compounds in CSS with hub-targeted genes were evaluated using molecular docking. Finally, hub-targeted genes were validated through real-time polymerase chain reaction, western blotting, and immunofluorescence in choline-deficient high-fat diet mice, both with and without CSS treatment. CSS reduces serum ALT and AST levels in NASH mice(P < 0.05) and ameliorates ballooning degeneration in the livers of NASH mice, thereby lowering the NAS score(P < 0.05). Including naringenin, high-performance liquid chromatography/mass spectrometrys identified 12 chromatographic peaks. Based on network pharmacology analysis, CSS contains a total of 103 active compounds and 877 target genes. Transferase activity represents a potential mechanism for therapeutic intervention of CSS in NASH. The transcriptional levels and protein expression of the SIRT1 gene in NASH mice are significantly increased by CSS (P < 0.05). Naringenin is probable active compound in CSS and SIRT1 is the hub gene by which CSS is involved in NASH treatment.

Transcriptome analysis of Citrus Aurantium L. to study synephrine biosynthesis during developmental stages.

Citrus aurantium L., sometimes known as "sour orange," is an important Chinese herb with young, immature fruits, or "zhishi," that are high in synephrine. Synephrine is a commonly utilized natural chemical with promising applications in effectively increasing metabolism, heat expenditure, energy level, oxidative fat, and weight loss. However, little is known about the genes and pathways involved in synephrine production during the critical developmental stages of C. aurantium L., which limits the development of the industry. According to this study, the concentration of synephrine gradually decreased as the fruit developed. Transcriptome sequencing was used to examine the DEGs associated with synephrine connections and served as the foundation for creating synephrine-rich C. aurantium L. Comparisons conducted between different developmental stages to obtain DEGs, and the number of DEGs varied from 690 to 3,019. Tyrosine and tryptophan biosynthesis, glycolysis/gluconeogenesis, pentose phosphate pathway, phenylalanine, and tyrosine metabolism were the main KEGG pathways that were substantially enriched. The results showed that 25 genes among these KEGG pathways may be related to synephrine synthesis. The WGCNA and one-way ANOVA analysis adoption variance across the groups suggested that 11 genes might play a crucial role in synephrine synthesis and should therefore be further analyzed. We also selected six DEGs at random and analyzed their expression levels by RT-qPCR, and high repeatability and reliability were demonstrated by our finished RNA-seq study results. These results may be useful in selecting or modifying genes to increase the quantity of synephrine in sour oranges.

Multi-Omics Exploration of the Mechanism of Curcumol to Reduce Invasion and Metastasis of Nasopharyngeal Carcinoma by Inhibiting NCL/EBNA1-Mediated UBE2C Upregulation.

Nasopharyngeal carcinoma (NPC) is closely linked to Epstein-Barr virus (EBV) infection. Curcumae Rhizoma, a traditional Chinese herb, has shown antitumor effects, primarily through its component curcumol (Cur), which has been shown to reduce NPC cell invasion and migration by targeting nucleolin (NCL) and Epstein-Barr Virus Nuclear Antigen 1 (EBNA1). We constructed an EBV-positive NPC cell model using C666-1 cells and performed transcriptomics studies after treatment with curcumol, which revealed a significant enrichment of ubiquitin-mediated proteolysis, the PI3K-AKT and mTOR signaling pathways, cell cycle and apoptosis involved in tumor invasion and migration. To investigate the importance of NCL and EBNA1 in curcumol-resistant EBV-positive NPC, we performed a multi-omics study using short hairpin NCL (shNCL) and shEBNA1 EBV-positive NPC cells, and the proteomics results showed enrichment in complement and coagulation cascades and ubiquitin-mediated proteolysis signaling pathways. Here, we focused on ubiquitin-conjugating enzyme E2C (UBE2C), which plays an important role in the ubiquitin-mediated proteolysis signaling pathway. In addition, metabolomics revealed that UBE2C is highly associated with 4-Aminobutanoic acid (GABA). In vitro studies further validated the function of the key targets, suggesting that UBE2C plays an important role in NCL and EBNA1-mediated curcumol resistance to nasopharyngeal carcinoma invasion and metastasis.

Mechanisms of traditional Chinese medicine in the treatment and prevention of gastric cancer

BackgroundGastric cancer (GC) ranks as the fifth most prevalent malignancy worldwide. Conventional treatments, including radiotherapy and chemotherapy, often induce severe side effects and significant adverse reactions, and they may also result in drug resistance. Consequently, there is a critical need for the development of new therapeutic agents. Traditional Chinese Medicine (TCM) and natural products are being extensively researched due to their low toxicity, multi-targeted approaches, and diverse pathways. Scholars are increasingly focusing on identifying active anticancer components within TCM. PurposeThis review aims to summarise research conducted over the past 14 years on the treatment of GC using TCM. The focus is on therapeutic targets, mechanisms, and efficacy of Chinese medicine and natural products, including monomer compounds, extracts or analogues, and active ingredients. MethodsRelevant articles on TCM and GC were retrieved from PubMed using appropriate keywords. The collected articles were screened and classified according to the types of TCM, with an emphasis on the molecular mechanisms underlying the treatment of GC. ResultsThe research on TCM indicates that TCM and natural products can effectively inhibit the metastasis, proliferation, and invasion of tumour cells. They can also induce apoptosis, autophagy and improve the chemosensitivity of drug-resistant cells. Additionally, injections derived from Chinese herbal medicine, when used as an adjunct to conventional chemotherapy, can significantly improve the prognosis of GC patients by reducing chemotherapy toxicity. ConclusionThis review summarises the progress of TCM treatment of GC over the past 14 years, and discusses its therapeutic application of GC, which proves that TCM is a promising treatment strategy for GC in the future.

Spatial Metabolomic Profiling of Pinelliae Rhizoma from Different Leaf Types Using Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Imaging.

Pinelliae Rhizoma (PR), a highly esteemed traditional Chinese medicinal herb, is widely applied in clinical settings due to its diverse pharmacological effects, including antitussive, expectorant, antiemetic, sedative-hypnotic, and antitumor activities. Pinellia ternata exhibits morphological variation in its leaves, with types resembling peach, bamboo, and willow leaves. However, the chemical composition differences among the corresponding rhizomes of these leaf phenotypes remain unelucidated. This pioneering research employed Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Imaging (MALDI-MSI) to conduct the in situ identification and spatial profiling of 35 PR metabolites in PR, comprising 12 alkaloids, 4 organic acids, 12 amino acids, 5 flavonoids, 1 sterol, and 1 anthraquinone. Our findings revealed distinct spatial distribution patterns of secondary metabolites within the rhizome tissues of varying leaf types. Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA) effectively differentiated between rhizomes associated with different leaf morphologies. Furthermore, this study identified five potential differential biomarkers-methylophiopogonanone B, inosine, cytidine, adenine, and leucine/isoleucine-that elucidate the biochemical distinctions among leaf types. The precise tissue-specific localization of these secondary metabolites offers compelling insights into the specialized accumulation of bioactive compounds in medicinal plants, thereby enhancing our comprehension of PR's therapeutic potential.

Enhancement of Active Substances in Astragali Radix Broth with Lactic Acid Bacteria Fermentation and the Promotion Role of Chlorella Growth Factor

Astragali Radix, a traditional Chinese herbal medicine widely used for its medicinal properties, is known to be rich in active components that possess various pharmacological effects. However, the effectiveness of microbial fermentation in enhancing the content of these active substances remains unclear. In this study, a microflora of lactic acid bacteria was used to ferment Astragali Radix, and the promoting effect of Chlorella Growth Factor (CGF) on the fermentation process was investigated so as to clarify the changes in major active compound content in the fermented Astragali Radix broth. Non-targeted metabolomic analysis based on ultra-high-performance liquid chromatography–mass spectrometry was conducted to analyze the differences in metabolites before and after fermentation. The results showed that the total polysaccharide, total flavonoid, and total saponin content in the fermented Astragali Radix broth increased by up to 51.42%, 97.76%, and 72.81% under the optimized conditions, respectively. Streptococcus lutetiensis was the dominant bacterial species during the fermentation process. There were significant differences in metabolites in the fermentation broth before and after fermentation, among which amino acids (such as L-Aspartyl-L-Phenylalanine, etc.) and saponin compounds (such as Cloversaponin I, Goyasaponin I, etc.) were the main upregulated metabolites, which can enhance the physiological functions of Astragali Radix fermentation broth. The CGF exhibited the ability to promote the increase of active substance content in the fermented Astragali Radix broth.

Effects of dietary immunostimulants on the growth and non-specific immune responses of hybrid sturgeons (Huso huso♀ × Acipenser ruthenus♂)

Herein, we investigated the effects of immunostimulants on the growth, immune responses, and post-infection survival of hybrid sturgeons (Huso huso♀ × Acipenser ruthenus♂). Therefore, we examined the effects of dietary supplementation of β-glucan, vitamin C, and Radix Bupleuri (Chaihu) extract (RBE) at various concentrations (0.2, 0.4, and 0.6% incorporated through feed) on the growth rate and non-specific immune responses of hybrid sturgeon. When supplemented individually, these immunostimulants significantly reduced the feed conversion ratio while promoting weight gain, with the vitamin C-administered groups showing the most pronounced differences. Further, we observed that dietary β-glucan, vitamin C, and RBE, when fed at 0.4 and 0.6% concentrations, significantly enhanced the rates of superoxide anion production and phagocytosis by head kidney leukocytes. Moreover, vitamin C and RBE supplementation at 0.4 and 0.6% and β-glucan supplementation at 0.6% concentration significantly increased the serum lysozyme activity. Further, vitamin C and β-glucan supplementation at 0.6% and RBE supplementation at 0.4 and 0.6% concentrations showed the highest survival rates after Aeromonas hydrophila infection. In conclusion, our findings highlight that the dietary supplementation of β-glucan, vitamin C, or RBE in appropriate concentrations can significantly enhance superoxide anion production and phagocytic activity of leukocytes, serum lysozyme activity, and the survival of hybrid sturgeons after A. hydrophila infection. Our results suggest that incorporating immunostimulants such as Chinese medicinal herbs at optimal levels can effectively boost the growth, immunity, and disease resistance of hybrid sturgeons in aquaculture. These results provide valuable insights for future studies on the inclusion of immunostimulants in aquaculture feed.

Selection of Reference Genes in Siraitia siamensis and Expression Patterns of Genes Involved in Mogrosides Biosynthesis.

Siraitia siamensis is a traditional Chinese medicinal herb. In this study, using S. siamensis cultivated in vitro, twelve candidate reference genes under various treatments were analyzed for their expression stability by using algorithms such as GeNorm, NormFinder, BestKeeper, Delta CT, and RefFinder. The selected reference genes were then used to characterize the gene expression of cucurbitadienol synthase, which is a rate-limiting enzyme for mogroside biosynthesis. The results showed that CDC6 and NCBP2 expression was the most stable across all treatments and are the best reference genes under the tested conditions. Utilizing the validated reference genes, we analyzed the expression profiles of genes related to the synthesis pathway of mogroside in S. siamensis in response to a range of abiotic stresses. The findings of this study provide clear standards for gene expression normalization in Siraitia plants and exploring the rationale behind differential gene expression related to mogroside synthesis pathways.
