Clinical value of modified Shenling Baizhu powder in treating targeted therapy-induced diarrhea in non-small cell lung cancer.

To assess clinical value of modified Shenling Baizhu powder (, SBP) in intervening targeted therapy-induced diarrhea. This study was a prospective randomized controlled study. Eighty-five non-small cell lung cancer (NSCLC) patients with diarrhea who took targeted drugs were randomly divided into two groups. The experimental group received modified SBP, while the control group received imodium. During 2 courses of treatment (1 week/course) and 2 weeks of follow-up, we observed remission and recurrence of diarrhea, as well as the improvement of Karnofsky score (KPS) in the two groups and drug safety. Eighty cases were completed, with 40 cases in the experimental group and 40 cases in the control group. The control group's diarrhea remission rate was significantly lower than the experimental group's (P<0.05). After 2 courses of treatment, the symptom scores of both groups were lower than before, with that of the experimental group remarkably lower (P<0.05). Furthermore, the experimental group experienced less abdominal fullness and appetite loss than the control group (P<0.05). There was no prominent difference in overall diarrhea recurrence, time, or KPS after treatment between the two groups (P>0.05). No unique adverse events occurred in experimental group or control group. The modified SBP could improve targeted therapy-induced diarrhea in NSCLC, and is superior to imodium in relieving diarrhea, improving related symptom scores and symptoms, with no obvious drug-related adverse events.

Study on the mechanism of Shenling Baizhu powder on the pathogenesis of pregnancy complicated with non-alcoholic fatty liver, based on PI3K/AKT/mTOR signal pathway.

This study investigates the effectiveness of Shenlin Baizhu powder in managing non-alcoholic fatty liver disease (NAFLD) during pregnancy and its mechanism through the PI3K/AKT/mTOR signaling pathway. Eight healthy male and 24 female Sprague-Dawley rats were used. After acclimatization, 6 female rats were fed normal chow, and 18 female rats were fed high-fat chow to induce NAFLD. After 8 weeks, female rats were mated with males to create a pregnant NAFLD model. The rats were divided into four groups: normal feeding, high-fat diet with saline, high-fat diet with 1.6 g/kg Shenlin Baizhu powder, and high-fat diet with 4.8 g/kg Shenlin Baizhu powder. Maternal body weight, serum and liver levels of aspartate aminotransferase (AST), alanine transaminase (ALT), triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), related inflammatory indexes interleukin-1 β (IL-1 β), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were measured. Liver tissue was examined using hematoxylin and oil red O staining, and protein expression related to the PI3K/AKT/mTOR pathway was assessed via Western blotting, immunohistochemistry and RT-PCR. Results showed significant weight gain and increases in ALT, AST, TG, TC, LDL-C, IL-1β, TNF-α, and IL-6, along with decreased HDL-C in NAFLD rats compared to controls. The high and low-dose Shenlin Baizhu powder groups exhibited improvements in body weight, liver histopathology, and reductions in serum TG, TC, LDL-C, ALT, AST, IL-1β, TNF-α, and IL-6, with increased HDL-C levels. Notably, the high-dose group showed greater efficacy in reducing hepatic fat accumulation, liver function markers, blood lipids, and inflammatory indexes, and decreased expression of hepatic PPARγ mRNA, SREBP1 mRNA, AKT mRNA, and related proteins. Shenlin Baizhu powder demonstrates potential in ameliorating high-fat diet-induced NAFLD in pregnant rats, likely through modulation of the PI3K/AKT/mTOR pathway, suggesting its therapeutic potential for gestational NAFLD.

Metabolomics study of Shenling Baizhu Powder in the treatment of multiple organ dysfunction syndrome in the elderly (MODSE) with malnutrition

Malnutrition is an important risk factor for multiple organ dysfunction syndrome in the elderly (MODSE) and seriously affects the occurrence, progression and prognosis of MODSE. Shenling Baizhu Power (SBP), a classic formula from traditional Chinese medicine (TCM), when integrated with enteral nutrition, has been proven to be an effective clinical strategy for treating the patients of MODSE with malnutrition. This study aimed to investigate the metabolic changes during disease occurrence and SBP treatment, and to discover potential metabolic biomarkers for the diagnosis and efficacy evaluation. An untargeted metabolomics strategy based on UHPLC-Q-Orbitrap-HRMS was performed to reveal the differential serum metabolites between MODSE patients with malnutrition (n=59) and healthy controls (n=33), and those between patients treated with enteral nutrition (n=31) and SBP combined with enteral nutrition (n=28). Significantly different metabolites were identified and mapped onto the network of metabolic pathways to explore the metabolic disorders caused by the disease and the metabolic regulatory mechanism of SBP. Additionally, the area under the curve (AUC) of the potential biomarkers was investigated for predicting the disease and the efficacy of SBP. Sixty differential metabolites were identified between the disease and control groups, which were mainly related to amino acid metabolism, energy metabolism and carbohydrate metabolism. In the same way, 50 differential metabolites associated with SBP treatment were identified, which improved metabolic abnormalities in vivo mainly by regulating the above-mentioned metabolic pathways. Finally, 13 differential metabolites in common were selected as the potential biomarkers and the AUC value of each biomarker was within the range of 0.8–1.0, indicating that these biomarkers had high prediction accuracy for the diagnosis and efficacy evaluation of MODSE with malnutrition. This study demonstrates that serum metabolomics approaches based on the UHPLC-Q-Orbitrap-HRMS platform can be applied as a tool to reveal the metabolic changes induced by MODSE with malnutrition and SBP can play an important role in the clinical application.

Shenling Baizhu powder attenuates lard diet in a fatigued state-induced diarrhea via targeting microbial metabolites short chain fatty acids-mediated lipid metabolism.

Shenling Baizhu Powder (SLBZP), a traditional Chinese medicine (TCM) prescription renowned for its efficacy, is specifically recognized for its therapeutic effects in managing diarrhea associated with spleen qi deficiency. Our previous research has demonstrated that a lard diet in a fatigued state induced diarrhea belonging to spleen qi deficiency in TCM. Through a comprehensive investigation, we aimed to provide insights into the intricate relationship between SLBZP and the modulation of gut microbiota in alleviating symptoms associated with spleen qi deficiency-induced diarrhea. We induced diarrhea in mice by subjecting them to continuous standing on a multiple-platform apparatus while administering lard through intragastric administration for 14days. Subsequently, we conducted gavage administration of SLBZP at a concentration of 0.637g/ml for seven days. We observed a therapeutic effect of SLBZP on diarrhea induced by a lard diet in a fatigued state. SLBZP mitigated disorders in lipid metabolism and diminished hepatic oxidative responses. Additionally, SLBZP reversed gut microbiota dysbiosis of diarrheic mice and notably increased the production of short-chain fatty acids (SCFAs), primarily acetic acid, butyric acid, and valeric acid. Through correlation analysis, we additionally identified Lactobacillus reuteri and Lactobacillus intestinalisas potentially pivotal species associated with the therapeutic effects of SLBZP. We demonstrated that SLBZP exerts therapeutic effects on diarrhea caused by a lard diet in a fatigued state by repairing the intestinal mucosal barrier, improving lipid metabolism disorders, and regulating gut microbiota and metabolites SCFAs.

Five commonly used traditional Chinese medicine formulas in the treatment of ulcerative colitis: A network meta-analysis.

Currently, traditional Chinese medicine (TCM) formulas are commonly being used as adjunctive therapy for ulcerative colitis in China. Network meta-analysis, a quantitative and comprehensive analytical method, can systematically compare the effects of different adjunctive treatment options for ulcerative colitis, providing scientific evidence for clinical decision-making. To evaluate the clinical efficacy and safety of commonly used TCM for the treatment of ulcerative colitis (UC) in clinical practice through a network meta-analysis. Clinical randomized controlled trials of these TCM formulas used for the adjuvant treatment of UC were searched from the establishment of the databases to July 1, 2022. Studies that met the inclusion criteria were screened and evaluated for literature quality and risk of bias according to the Cochrane 5.1 standard. The methodological quality of the studies was assessed using ReviewManager (RevMan) 5.4, and a funnel plot was constructed to test for publication bias. ADDIS 1.16 statistical software was used to perform statistical analysis of the treatment measures and derive the network relationship and ranking diagrams of the various intervention measures. A total of 64 randomized controlled trials involving 5456 patients with UC were included in this study. The adjuvant treatment of UC using five TCM formulations was able to improve the clinical outcome of the patients. Adjuvant treatment with Baitouweng decoction (BTWT) showed a significant effect [mean difference = 36.22, 95% confidence interval (CI): 7.63 to 65.76]. For the reduction of tumor necrosis factor in patients with UC, adjunctive therapy with BTWT (mean difference = -9.55, 95%CI: -17.89 to -1.41), Shenlingbaizhu powder [SLBZS; odds ratio (OR) = 0.19, 95%CI: 0.08 to 0.39], and Shaoyao decoction (OR = -23.02, 95%CI: -33.64 to -13.14) was effective. Shaoyao decoction was more effective than BTWT (OR = 0.12, 95%CI: 0.03 to 0.39), SLBZS (OR = 0.19, 95%CI: 0.08 to 0. 39), and Xi Lei powder (OR = 0.34, 95%CI: 0.13 to 0.81) in reducing tumor necrosis factor and the recurrence rate of UC. TCM combined with mesalazine is more effective than mesalazine alone in the treatment of UC.

Shenling Baizhu powder alleviates non-alcoholic fatty liver disease by modulating autophagy and energy metabolism in high-fat diet-induced rats

BackgroundNon-alcoholic fatty liver disease (NAFLD) has emerged as a burgeoning health problem worldwide, but no specific drug has been approved for its treatment. Shenling Baizhu powder (SL) is extensively used to treat NAFLD in Chinese clinical practice. However, the therapeutic components and pharmacological mechanisms of SL against NAFLD have not been thoroughly investigated. PurposeThis study aimed to investigate the pharmacological impact and molecular mechanism of SL on NAFLD. MethodsFirst, we established an animal model of NAFLD by high-fat diet (HFD) feeding, and evaluated the therapeutic efficacy of SL on NAFLD by physiological, biochemical, pathological, and body composition analysis. Next, the effect of SL on autophagic flow in NAFLD rats was evaluated by ultrastructure, immunofluorescence staining, and western blotting. Moreover, an integrated strategy of targeted energy metabolomics and network pharmacology was performed to characterize autophagy-related genes and explore the synergistic effects of SL active compounds. UPLC-MS/MS, molecular docking combined with in vivo and in vitro experiments were conducted to verify the key compounds and genes. Finally, a network was established among SL-herb-compound-genes-energy metabolites-NAFLD, which explains the complicated regulating mechanism of SL on NAFLD. ResultsWe discovered that SL decreased hepatic lipid accumulation, hepatic steatosis, and insulin resistance, and improved systemic metabolic disorders and pathological abnormalities. Subsequently, an integrated strategy of targeted energy metabolomics and network pharmacology identified quercetin, ellagic acid, kaempferol, formononetin, stigmasterol, isorhamnetin and luteolin as key compounds; catalase (CAT), AKT serine/threonine kinase 1 (AKT), nitric oxide synthase 3 (eNOS), NAD(P)H quinone dehydrogenase 1 (NQO1), heme oxygenase 1 (HO-1) and hypoxia-inducible factor 1 subunit alpha (HIF-1α) were identified as key genes; while nicotinamide adenine dinucleotide phosphate (NADP) and succinate emerged as key energy metabolites. Mechanistically, we revealed that SL may exert its anti-NAFLD effect by inducing autophagy activation and forming a comprehensive regulatory network involving key compounds, key genes, and key energy metabolites, ultimately alleviating oxidative stress, endoplasmic reticulum stress, and mitochondrial dysfunction. ConclusionOur study demonstrated the therapeutic effect of SL in NAFLD models, and establishes a basis for the development of potential products from SL plant materials for the treatment of NAFLD.

Efficacy and safety of Chinese patent medicine combined with 5-aminosalicylic acid for patients with ulcerative colitis: A network meta-analysis of randomized controlled trials

ObjectivesGiven the widespread use of Chinese patent medicines (CPMs) in combination with 5-aminosalicylic acid (5-ASA) for Ulcerative colitis (UC) patients, this study aimed to evaluate the efficacy and safety of nine CPMs combined with 5-ASA in the treatment of UC. MethodsA systematic literature search was conducted in eight databases from inception to May 2023 to identify eligible RCTs evaluating the effects of CPM combined with 5-ASA for the treatment of UC. The methodological quality of the included RCTs was assessed using the Cochrane risk of bias tool in Review Manager 5.4. The primary outcome of the meta-analysis was the overall response rate. The secondary outcomes included excellent rate, disease activity index (DAI), IL-6, IL-8, and TNF-α levels, mean platelet volume (MPV), fibrinogen (FIB) levels, recurrence rate, and adverse event rate. Network meta-analysis was performed using Review Manager 5.4 and Stata 15.0. ResultsIn total, 70 RCTs including 5973 patients and 10 treatment regimens were included. The combination of Kangfuxin Liquid (KFL) and 5-ASA showed the greatest efficacy in improving FIB levels and the overall response rate. Bupi Yichang Pill (BYP) combined with 5-ASA was associated with the fewest adverse events and the lowest recurrence rate. Hudi Enteric-coated Capsule (HEC) combined with 5-ASA ranked first in improving DAI. ZhiKang Capsule (ZKC), ChangYanNing Capsule (CYN), and Danshen Injection (DSI) combined with 5-ASA ranked first in improving IL-6, IL-10, and TNF-α levels, respectively. Shenling Baizhu Powder (SBP) combined with 5-ASA was associated with the highest excellent rate. ConclusionsCPM combined with 5-ASA may be more effective than 5-ASA alone for treating UC. Besides, CPM combined with 5-ASA could better reduce the recurrence rate and adverse event rate in UC patients. The current meta-analysis provides statistical evidence for clinical application.Systematic Review Registration: International Prospective Register of Systematic Reviews (PROSPERO), No. CRD42023433672.

Mechanism of Shenling Baizhu Powder on treatment of alcoholic liver disease by regulating TLR4/NLRP3 pathway

This study aims to investigate the regulatory effects of Shenling Baizhu Powder(SBP) on cellular autophagy in alcoholic liver disease(ALD) and its intervention effect through the TLR4/NLRP3 pathway. A rat model of chronic ALD was established by gavage of spirits. An ALD cell model was established by stimulating BRL3A cells with alcohol. High-performance liquid chromatography(HPLC) was utilized for the compositional analysis of SBP. Liver tissue from ALD rats underwent hematoxylin-eosin(HE) and oil red O staining for pathological evaluation. Enzyme-linked immunosorbent assay(ELISA) was applied to quantify lipopolysaccharides(LPS), tumor necrosis factor-alpha(TNF-α), interleukin-1 beta(IL-1β), and interleukin-18(IL-18) levels. Quantitative reverse transcription polymerase chain reaction(qRT-PCR) was conducted to evaluate the mRNA expression of myeloid differentiation factor 88(MyD88) and Toll-like receptor 4(TLR4). The effect of different drugs on BRL3A cell proliferation activity was assessed through CCK-8 analysis. Western blot analysis was performed to examine the protein expression of NOD-like receptor pyrin domain-containing 3(NLRP3), nuclear factor-kappa B P65(NF-κB P65), phosphorylated nuclear factor-kappa B P65(p-P65), caspase-1, P62, Beclin1, and microtubule-associated protein 1 light chain 3(LC3Ⅱ). The results showed that SBP effectively ameliorated hepatic lipid accumulation, reduced liver function, mitigated hepatic tissue inflammation, and reduced levels of LPS, TNF-α, IL-1β, and IL-18. Moreover, SBP exhibited the capacity to modulate hepatic autophagy induced by prolonged alcohol intake through the TLR4/NLRP3 signaling pathway. This modulation resulted in decreased expression of LC3Ⅱ and Beclin1, an elevation in P62 expression, and the promotion of autolysosome formation. These research findings imply that SBP can substantially enhance liver function and mitigate lipid irregularities in the context of chronic ALD. It achieves this by regulating excessive autophagic responses caused by prolonged spirit consumption, primarily through the inhibition of the TLR4/NLRP3 pathway.

Network pharmacology and gut microbiota insights: unraveling Shenling Baizhu powder's role in psoriasis treatment.

Background: Psoriasis, a chronic skin condition characterized by systemic inflammation and altered gut microbiota, has been a target of Traditional Chinese Medicine (TCM) for centuries. Shenling Baizhu Powder (SLBZP), a TCM formulation, holds promise for treating inflammatory diseases, but its specific role in psoriasis and impact on gut microbiota is not fully understood. Objective: This study aims to elucidate the mechanism of SLBZP in treating psoriasis, integrating component analysis, network pharmacology, and experimental validation in mice models. Methods: We commenced with a detailed component analysis of SLBZP using liquid chromatograph and mass spectrometer (LC-MS). Network pharmacology analysis was used to predict the potential action targets and pathways of SLBZP in psoriasis. An in vivo experiment was conducted with psoriasis mice models, treated with SLBZP. Therapeutic effects were assessed via symptomatology, histopathology, and immunohistochemical analysis. Gut microbiota composition was analyzed using 16S rRNA gene sequencing. Results: A total of 42 main components and quality markers were identified, primarily from licorice and ginseng, including flavonoids, saponins and other markers. PPI topology analysis showed that TNF, IL-6, IL-1β, TP53 and JUN were the core DEPs. 168 signaling pathways including lipid and atherosclerosis, AGE-RAGE signaling pathway, IL-17 signaling pathway and Th17 cell differentiation were enriched by KEGG. SLBZP demonstrated significant therapeutic effects on psoriasis in mice, with alterations in skin pathology and biomarkers. Additionally, notable changes in gut microbiota composition were observed post-treatment, indicating a possible gut-skin axis involvement. Conclusion: This research has pinpointed lipid metabolism as a key pathway in the treatment of psoriasis with SLBZP. It explores how SLBZP's modulation of gut microbiota and lipid metabolism can alleviate psoriasis, suggesting that balancing gut microbiota may reduce inflammation mediators and offer therapeutic benefits. This underscores lipid metabolism modulation as a potential new strategy in psoriasis treatment.

Quantitative proteomics analysis based on data-independent acquisition reveals the effect of Shenling Baizhu powder (SLP) on protein expression in MAFLD rat liver tissue

BackgroundMetabolic associated fatty liver disease (MAFLD) has become the most common chronic liver disease worldwide, and it is also a high-risk factor for the development of other metabolic diseases. Shenling Baizhu powder (SLP) is a traditional Chinese herbal formula with good clinical efficacy against MAFLD. However, its molecular mechanism for the treatment of MAFLD is still not fully understood. This study used quantitative proteomics analysis to reveal the SLP action mechanism in the treatment of MAFLD by discovering the effect of SLP on protein expression in the liver tissue of MAFLD rats.Materials and methodsQ-Orbitrap LC–MS/MS was used to identify the incoming blood compounds of SLP. The 18 SD male rats were randomly divided into 3 groups (n = 6): control group, HFD group and SLP group. The HFD group and SLP group were established as MAFLD rat models by feeding them a high-fat diet for 4 weeks. Afterwards, the SLP group was treated with SLP (10.89 g/kg/d) for 3 weeks. Biochemical parameters and liver pathological status were measured. Rat liver tissue was analyzed using DIA-based quantitative proteomics and the DEPs were validated by western blotting analysis.ResultsA total of 18 active compounds of SLP were identified and isolated to enter the bloodstream. Comparison of DEPs between control group vs. HFD group and HFD group vs. SLP group revealed that SLP restored the expression of 113 DEPs. SLP catalyzes oxidoreductase activity and binding activity on mitochondria and endoplasmic reticulum to promote lipid oxidative catabolism, maintain oxoacid metabolic homeostasis in vivo and mitigate oxidative stress-induced hepatocyte injury. And 52 signaling pathways including PPAR signaling, arachidonic acid metabolism and glycine, serine and threonine metabolism were enriched by KEGG. PPI topology analysis showed that Cyp4a2, Agxt2, Fabp1, Pck1, Acsm3, Aldh1a1, Got1 and Hmgcs2 were the core DEPs. The western blotting analysis verified that SLP was able to reverse the increase in Fabp1 and Hmgcs2 and the decrease in Pck1 induced by HFD, and the results were consistent proteomic data.ConclusionSLP ameliorates hepatic steatosis to exert therapeutic effects on MAFLD by inhibiting the expression of lipid synthesis genes and inhibiting lipid peroxidation in mitochondria. This study provides a new idea and basis for the study of SLP in the treatment of MAFLD and provides an experimental basis for the clinical application of SLP.

Effects of Shenling Baizhu powder on intestinal microflora metabolites and liver mitochondrial energy metabolism in nonalcoholic fatty liver mice.

Non-alcoholic fatty liver disease (NAFLD) is characterised by the excessive accumulation of triglycerides in the liver. Shenling Baizhu powder (SLBZP) is formulated from various natural medicinal plants that protect the liver and are used to treat intestinal diseases. SLBZP improves the symptoms of NAFLD. However, its mechanism of action remains unclear. Herein, we investigated the ameliorative effect of SLBZP on model mice with high-fat-diet (HFD)-induced NAFLD. Additionally, we evaluated the impact of SLBZP on the intestinal flora and its metabolites and mitochondrial energy metabolism in NAFLD. We used HFD to establish a mouse model of NAFLD. Different drug interventions were administered. We measured serum biochemical indices. Liver sections were visualised with hematoxylin-eosin and oil red O staining. 16S rDNA amplicon sequencing technology was used to analyse the diversity and abundance of the intestinal flora. Short-chain fatty acids (SCFAs) in the intestinal contents were detected using GC-MS. Liver tissue was sampled to detect mitochondrial membrane functional indices. Western blotting was used to determine the levels of mitochondrial pathway-related proteins, namely, uncoupling protein 2 (UCP2), adenosine monophosphate-activated protein kinase (AMPK) and inhibitory factor 1 (IF1) of F1Fo ATP synthesis/hydrolase, in the liver. The spleen-invigorating classic recipe of SLBZP reduced liver lipid deposition in mice with HFD-induced NAFLD. Additionally, SCFAs produced by intestinal flora metabolism regulated the UCP2/AMPK/IF1 signalling pathway involved in liver mitochondrial energy metabolism to improve the liver mitochondrial membrane permeability, respiratory state and oxidative phosphorylation efficiency of mice with NAFLD. Finally, SLBZP increased the liver ATP level. Our results suggest that the therapeutic effect of SLBZP on NAFLD is related to the regulation of hepatic mitochondrial energy metabolism by intestinal flora and its metabolites and is possibly associated with the UCP2/AMPK/IF1 signalling pathway.

RNA-seq based transcriptome analysis of murine macrophages RAW264.7 treated with multi-herbal extracts reveals immunomodulatory potential and mechanism

ABSTRACT Shenling Baizhu Powder is a traditional Chinese medicine formula that has been used for thousands of years to invigorate spleen, nourish stomach and regulate immune function. The multi-herbal extracts, an improved formular from Shenling Baizhu Powder, were used in our study to investigate its immune-enhancing effects and underling mechanisms. Based on UPLC-Q-TOF-MS and SPME-GC-MS analysis, 106 chemical compounds were identified from the extracts. In vitro assays indicated that the extracts could promote cell proliferation and NO secretion of RAW264.7 cells. RNA-seq and RT-qPCR showed that RAW264.7 cells treated with extracts increased the expression of pro-inflammatory factors IL-1β, iNOS, TNF-α, and TGF-β. Western-Blot revealed that the extracts could significantly enhance ERK phosphorylation level, and slightly increased JNK and p38 phosphorylation levels. These data suggest that multi-herbal extracts have a potential of regulating immune response via the JNK/p38/ERK signalling of MAPK pathways in RAW264.7 cells.

Effects of Shenling Baizhu powder on pyrotinib-induced diarrhea: analysis of gut microbiota, metabonomics, and network pharmacology

BackgroundShenling Baizhu Powder (SBP) is a traditional Chinese medicine (TCM) prescription, which has the good efficacy on gastrointestinal toxicity. In this study, we used gut microbiota analysis, metabonomics and network pharmacology to investigate the therapeutic effect of SBP on pyrotinib-induced diarrhea.Methods24 Rats were randomly divided into 4 groups: control group, SBP group (3.6 g/kg /bid SBP for 10 days), pyrotinib model group (80 mg/kg/qd pyrotinib) and pyrotinib + SBP treatment group. A 16S rRNA sequencing was used to detect the microbiome of rat fecal bowel. Metabolic profiles were collected by non-targeted metabolomics and key metabolic pathways were identified using MetaboAnalyst 5.0. The antitumor effect of SBP on cells treated with pyrotinib was measured using a CCK-8 assay. Network pharmacology was used to predict the target and action pathway of SBP in treating pyrotinib-related diarrhea.ResultsIn vivo study indicated that SBP could significantly alleviate pyrotinib-induced diarrhea, reaching a therapeutic effect of 66.7%. SBP could regulate pyrotinib-induced microbiota disorder. LEfSe research revealed that the SBP could potentially decrease the relative abundance of Escherichia, Helicobacter and Enterobacteriaceae and increase the relative abundance of Lachnospiraceae, Bacilli, Lactobacillales etc. In addition, 25-Hydroxycholesterol, Guanidinosuccinic acid, 5-Hydroxyindolepyruvate and cAMP were selected as potential biomarkers of SBP for pyrotinib-induced diarrhea. Moreover, Spearman's analysis showed a correlation between gut microbiota and metabolite: the decreased 25-hydroxycholesterol in the pyrotinib + SBP treatment group was negatively correlated with Lachnospiraceae while positively correlated with Escherichia and Helicobacter. Meanwhile, SBP did not affect the inhibitory effect of pyrotinib on BT-474 cells and Calu-3 cells in vitro. Also, the network analysis further revealed that SBP treated pyrotinib-induced diarrhea through multiple pathways, including inflammatory bowel disease, IL-17 signaling pathway, pathogenic Escherichia coli infection and cAMP signaling pathway.ConclusionsSBP could effectively relieve pyrotinib-induced diarrhea, revealing that intestinal flora and its metabolites may be involved in this process.

Mechanism of Shenling Baizhu Powder in alleviation of ulcerative colitis in mice based on high-throughput transcriptome sequencing

High-throughput transcriptome sequencing was used to study the mechanism of Shenling Baizhu Powder(SLBZP) in the alleviation of the dextran sulfate sodium(DSS)-induced ulcerative colitis(UC) in mice. The mouse model of DDS-induced UC was treated with SLBZP by gavage. The changes in general state, disease activity index(DAI), and colon length were observed. The hematoxylin-eosin(HE) staining was used to observe the pathological changes in the colon tissues of mice. Enzyme-linked immunosorbent assay(ELISA) was used to determine the expression levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-1β, IL-6, IL-4, and IL-10 in the serum and tissues of mice. The differentially expressed genes in the control group, the model group, and the SLBZP group were analyzed by high-throughput transcriptome sequencing, and the Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses were conducted on the differentially expressed genes. The results showed that after intragastric administration of SLBZP, the symptoms of diarrhea and bloody stool were improved, and the disease active index(DAI) score was reduced. SLBZP effectively reduced the inflammatory cell infiltration and goblet cell loss in the colonic mucosal tissue, reduced the levels of TNF-α, IL-1β, IL-6 in the serum and colon tissue, and increased the levels of IL-4 and IL-10 in the serum and colon tissue. There were 25 differential genes in SLBZP vs the model group, which were significantly enriched in immune response, immune system process, immunoglobulin production, and other biological processes. KEGG pathway analysis showed that the differential genes were enriched in signaling pathways such as neomycin, kanamycin, and gentamicin biosynthesis, cytokine-cytokine receptor interaction, primary immunodeficiency, and IgA synthesis of the intestinal immune network. This study shows that SLBZP may alleviate UC through immune regulation.

Mechanism of Shenling Baizhu Powder on treatment of ulcerative colitis based on NLRP3 inflammatory

This study deciphered the mechanism of Shenling Baizhu Powder in treatment of mouse model of ulcerative colitis(UC) via NOD-like receptor thermoprotein domain 3(NLRP3) signaling pathway. After three days of adaptive feeding, 70 SPF-grade BALB/c mice were randomized into 7 groups: normal group, model group(dextran sodium sulfate, DSS), mesalazine group(DSS + 5-aminosalicylic acid, 5-ASA), NLRP3 inhibitor group(DSS + MCC950), and high-, medium-, and low-dose Shenling Baizhu Powder groups(DSS + high-, medium-, and low-dose Shenling Baizhu Powder), with 10 mice per group. The normal group had free access to double distilled water, and the remaining groups had free access to DSS-containing water to establish the acute UC model. Intragastric administration was started at the same time as modeling for one week. During the experiment, the general mental state and disease activity of each group of mice were recorded and scored. After the experiment, colon and serum samples were collected. The pathological changes in colon tissue were observed through hematoxylin-eosin(HE) staining. Enzyme-linked immunosorbent assay(ELISA) was employed to determine the levels of interleukin-18(IL-18) and myeloperoxidase(MPO) in colon tissue and interleukin-1β(IL-1β) in serum. Immunofluorescence(IF) and immunohistochemistry(IHC) methods were employed to examine the expression of NLRP3 and IL-18 in colon tissue. Western blot was employed to measure the protein levels of NLRP3, apoptosis-associated speck-like protein(ASC), cystein-aspartate protease 1(caspase-1), and downstream inflammatory cytokines in colon tissue. Compared with the normal group, the modeling of UC increased the disease activity index(DAI), colon pathological injury score, IL-1β level in serum, and IL-18 and MPO levels in colon tissue(P&lt;0.05, P&lt;0.01). Furthermore, the modeling caused obvious pathological changes and up-regulated the expression of NLRP3, caspase-1, ASC, pro-IL-1β, cleaved-IL-1β, pro-IL-18, and cleaved-IL-18 in the colon(P&lt;0.01). Compared with the model group, the administration of corresponding drugs decreased the DAI, pathological injury score, IL-1β level in serum, and IL-18 and MPO levels in colon tissue, and down-regulated the protein levels of NLRP3, caspase-1, ASC, pro-IL-1β, cleaved-IL-1β, pro-IL-18, and cleaved-IL-18 in the colon(P&lt;0.05, P&lt;0.01). According to the results of previous study and this study, we concluded that Shenling Baizhu Powder can alleviate the inflammatory response and intestinal damage of DSS-induced UC by regulating the expression of the proteins and inflammatory cytokines associated with NLRP3 signaling pathway.

Chinese medicinal formulae treat inflammatory bowel diseases through maintaining gut flora homeostasis

Inflammatory bowel disease(IBD) is a chronic and recurrent inflammatory disorder of the gut, including Crohn's disease(CD) and ulcerative colitis(UC). The occurrence and development of IBD involves multiple pathogenic factors, and the dybiosis of gut flora is recognized as an important pathogenic mechanism of IBD. Therefore, restoring and maintaining the balance of gut flora including bacteria and fungi has become an effective option for IBD treatment. Based on the theoretical basis of the interaction between gut flora and IBD, this paper followed the principle of clinical syndrome differentiation for IBD therapy by traditional Chinese medicine(TCM), and summarized several Chinese medicinal formulae commonly used in IBD patients with large intestine damp-heat syndrome, intermingled heat and cold syndrome, spleen deficiency and dampness accumulation syndrome, spleen and kidney yang deficiency syndrome, liver stagnation and spleen deficiency syndrome, and severe heat poisoning syndrome. The therapeutic and regulatory effects of Shaoyao Decoction, Qingchang Suppository, Wumei Pills, Banxia Xiexin Decoction, Shenling Baizhu Powder, Lizhong Decoction, Sishen Pills, Tongxie Yaofang, Baitouweng Decoction, Gegen Qinlian Decoction, and Houttuyniae Herba prescriptions on gut flora of IBD patients were emphasized as well as the mechanisms. This study found that Chinese medicinal formulae increased the abundance of Bacteroidetes, Bifidobacteria, Lactobacillus, and other beneficial bacteria producing short-chain fatty acids, and reduced the abundance of Enterobacteriaceae and other harmful bacteria to restore the balance of gut flora, thus treating IBD. Confronting the recalcitrance and high recurrence of IBD, Chinese medicinal formulae provide new opportunities for IBD treatment through intervening dysbiosis of gut flora.

Analysis of absorbed constituents and network pharmacology research of Xiaoer Fupi Granules

Xiaoer Fupi Granules, a refined version of the classical prescription Shenling Baizhu Powder, has the effect of invigora-ting spleen, replenishing Qi, harmonizing stomach and resolving accumulation and is commonly used to treat Qi deficiency in spleen and stomach, disordered transportation and transformation, and indigestion of children. However, its medicinal constituents and mechanism remain unclear. We studied the main active constituents and action mechanism of Xiaoer Fupi Granules by integrating network pharmacology and prototype constituent analysis in vivo. This study will help to increase the reliability of database analysis results and lay a foundation for precise medication and mining of quality control markers. On the basis of Bioinformatics Analysis Tool for Molecular mechanism of Traditional Chinese Medicine(BATMAN-TCM), the &quot;key chemical constituents-target&quot; network was constructed. Ultra-performance liquid chromatography coupled with linear ion trap-orbitrap mass spectrometry(UPLC-LTQ-Orbitrap-MS) was employed to analyze the absorbed constituents in rat urine and plasma, so as to validate the network. Further, we used BATMAN-TCM to construct the &quot;absorbed constituents-target-pathway&quot; network and explore the functioning mechanism of Xiaoer Fupi Granules. A total of 86 chemical constituents of Xiaoer Fupi Granules were predicted via BATMAN-TCM, among which only 18.6% were detected in rat plasma and urine. Accor-ding to the &quot;absorbed constituents-target-pathway&quot; network, 8 chemical constituents such as stearic acid and caprylic acid capable of regulating gastric acid and insulin secretion may be the critical constituents of Xiaoer Fupi Granules in invigorating spleen and harmonizing stomach. This study identified the critical active constituents and predicted the action mechanism of Xiaoer Fupi Granules, providing the reference for the research on the material basis of Xiaoer Fupi Granules.
