RESUMO

Background: The escalation of global population aging has accentuated the prominence of senile diabetes mellitus (SDM) as a consequential public health concern. Oxidative stress and chronic inflammatory cascades prevalent in individuals with senile diabetes significantly amplify disease progression and complication rates. Traditional Chinese Medicine (TCM) emerges as a pivotal player in enhancing blood sugar homeostasis and retarding complication onset in the clinical management of senile diabetes. Nonetheless, an evident research gap persists regarding the integration of TCM's renal tonification pharmacological mechanisms with experimental validation within the realm of senile diabetes therapeutics. Aims: The objective of this study was to investigate the mechanisms of action of New Shenqi Pills (SQP) in the treatment of SDM and make an experimental assessment. Methods: Network analysis is used to evaluate target pathways related to SQP and SDM. Mitochondrial-related genes were obtained from the MitoCarta3.0 database and intersected with the common target genes of the disease and drugs, then constructing a protein-protein interaction (PPI) network making use of the GeneMANIA database. Representative compounds in the SQP were quantitatively measured using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) to ensure quality control and quantitative analysis of the compounds. A type 2 diabetes mice (C57BL/6) model was used to investigate the pharmacodynamics of SQP. The glucose lowering efficacy of SQP was assessed through various metrics including body weight and fasting blood glucose (FBG). To elucidate the modulatory effects of SQP on pancreatic beta cell function, we measured oral glucose tolerance test (OGTT), insulin histochemical staining and tunel apoptosis detection, then assessed the insulin-mediated phosphoinositide 3-kinase (PI3K)/protein kinase A (Akt)/glycogen synthase kinase-3ß (GSK-3ß) pathway in diabetic mice via Western blotting. Additionally, we observe the structural changes of the nucleus, cytoplasmic granules and mitochondria of pancreatic islet ß cells. Results: In this investigation, we identified a total of 1876 genes associated with senile diabetes, 278 targets of SQP, and 166 overlapping target genes, primarily enriched in pathways pertinent to oxidative stress response, peptide response, and oxygen level modulation. Moreover, an intersection analysis involving 1,136 human mitochondrial genes and comorbidity targets yielded 15 mitochondria-related therapeutic targets. Quality control assessments and quantitative analyses of SQP revealed the predominant presence of five compounds with elevated concentrations: Catalpol, Cinnamon Aldehyde, Rehmanthin D, Trigonelline, and Paeonol Phenol. Vivo experiments demonstrated notable findings. Relative to the control group, mice in the model group exhibited significant increases in body weight and fasting blood glucose levels, alongside decreased insulin secretion and heightened islet cell apoptosis. Moreover, ß-cells nuclear condensation and mitochondrial cristae disappearance were observed, accompanied by reduced expression levels of p-GSK-3ß protein in islet cells (p < 0.05 or p < 0.01). Conversely, treatment groups administered SQP and Rg displayed augmented expressions of the aforementioned protein markers (p < 0.05 or p < 0.01), alongside preserved mitochondrial cristae structure in islet ß cells. Conclusion: Our findings suggest that SQP can ameliorate diabetes by reducing islet cell apoptosis and resist oxidative stress. These insulin-mediated PI3K/AKT/GSK-3ß pathway plays an important regulatory role in this process.

RESUMO

Cancer-related fatigue (CRF) significantly impacts the quality of life of cancer patients. This study investigates the therapeutic potential of Shenqi Fuzheng injection (SFI) in managing CRF, focusing on its mechanistic action in skeletal muscle. We utilized a CRF mouse model to examine the effects of SFI on physical endurance, monitoring activity levels, swimming times and rest periods. Proteomic analysis of the gastrocnemius muscle was performed using isobaric tags and liquid chromatography-tandem mass spectrometry to map the muscle proteome changes post-SFI treatment. Mitochondrial function in skeletal muscle was assessed via ATP bioluminescence assay. Furthermore, the regulatory role of the hypoxia inducible factor 1 subunit alpha (HIF-1α) signalling pathway in mediating SFI's effects was explored through western blotting. In CRF-induced C2C12 myoblasts, we evaluated cell viability (CCK-8 assay), apoptosis (flow cytometry) and mitophagy (electron microscopy). The study also employed pulldown, luciferase and chromatin immunoprecipitation assays to elucidate the molecular mechanisms underlying SFI's action, particularly focusing on the transcriptional regulation of PINK1 through HIF-1α binding at the PINK1 promoter region. Our findings reveal that SFI enhances physical mobility, reduces fatigue symptoms and exerts protective effects on skeletal muscles by mitigating mitochondrial damage and augmenting antioxidative responses. SFI promotes cell viability and induces mitophagy while decreasing apoptosis, primarily through the modulation of HIF-1α, PINK1 and p62 proteins. These results underscore SFI's efficacy in enhancing mitochondrial autophagy, thereby offering a promising approach for ameliorating CRF. The study not only provides insight into SFI's potential therapeutic mechanisms but also establishes a foundation for further exploration of SFI interventions in CRF management.

RESUMO

Introduction: Herbal formulations are renowned for their complex biological activities, acting on multiple targets and pathways, as evidenced by in vitro studies. However, the hypoglycemic effect and underlying mechanisms of Shenqi Compound (SQ), a traditional Chinese herbal formula, remain elusive. This study aimed to elucidate the hypoglycemic effects of SQ and explore its mechanisms of action, focusing on intestinal flora and metabolomics. Methods: A Type 2 diabetes mellitus (T2DM) rat model was established through a high-fat diet, followed by variable glucose and insulin injections to mimic the fluctuating glycemic conditions seen in diabetes. Results: An eight-week regimen of SQ significantly mitigated hyperglycemia, inflammation, and insulin resistance in these rats. Notably, SQ beneficially modulated the gut microbiota by increasing populations of beneficial bacteria, such as Lachnospiraceae_NK4A136_group and Akkermansia, while reducing and inhibiting harmful strains such as Ruminococcus and Phascolarctobacterium. Metabolomics analyses revealed that SQ intervention corrected disturbances in Testosterone enanthate and Glycerophospholipid metabolism. Discussion: Our findings highlight the hypoglycemic potential of SQ and its mechanisms via modulation of the gut microbiota and metabolic pathways, offering a theoretical foundation for the use of herbal medicine in diabetes management.

RESUMO

The proprietary Chinese medicine Jinkui Shenqi Pill (PCM-JKSQP) is a classic compound used for the effective clinical treatment of kidney yang deficiency syndrome (KYDS), a metabolic disease accompanied by kidney injury. However, its active ingredients and therapeutic mechanisms are not clear. This study employed serum pharmacochemistry, network pharmacology, and pharmacokinetics (PK) to identify the bioactive components of PCM-JKSQP and preliminarily clarify its mechanism in treating KYDS. One hundred and forty chemical components of PCM-JKSQP, 47 (20 parent compouds and 27 metabolites) of which were absorbed into the blood, were identified by ultra-high-performance liquid chromatography-quadrupole-orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS). The topological parameters of network pharmacology and high concentrations in blood found six parent components as PK markers (cinnamic acid, paeonol, loganin, morroniside, apigenin, and poricoic acid A). PK analysis further identified these six compounds as active ingredients. Protein-protein interaction (PPI) analysis and molecular docking simulation predicted and verified eight core targets (TP53, ESR1, CTNNB1, EP300, EGFR, AKT1, ERBB2, and TNF). Most were concentrated in the MAPK, HIF-1, and PI3K-AKT signaling pathways, indicating that these six active ingredients may mainly exert therapeutic effects through these three pathways via their core targets. The PK results also showed these six components were absorbed quickly, although cinnamic acid and paeonol were rapidly metabolized, with a short half-life and retention time. Loganin and morroniside did not have high peak concentrations, and apigenin and poricoic acid A had long retention times. This study provides a new overall perspective for exploring the bioactive components and mechanisms underlying the effects of PCM-JKSQP in treating KYDS.

RESUMO

INTRODUCTION: Lung cancer (LC) is the most common solid tumor and is currently considered the primary cause of cancer-related deaths worldwide. In clinical efficacy studies, it was not difficult to find that the combination of SFI and chemotherapy could improve the general condition of patients, reduce the side effects of chemotherapy drugs, and have a cooperative antitumor effect in NSCLC patients. However, whether SFI can be used as a novel antitumor drug is still unknown. METHODS: First, meta-analysis aimed to explore the efficacy of SFI in NSCLC patients, and SFI was identified by ultra-performance liquid chromatography‒mass spectrometry (UPLC‒MS). Cell proliferation, migration, and invasion were explored by Cell Counting Kit-8 (CCK-8), scratch healing, and Transwell assays, respectively. Cell cycle and apoptosis assays were performed by flow cytometry. Transcriptome sequencing analysis was performed in four NSCLC cell lines. Differential expression analysis was used to identify potential targets. Apoptosis-related protein levels were detected by Western blotting assays. The effects of SFI in NSCLC were further investigated by mouse xenografts. RESULTS: SFI could markedly improve the chemotherapy efficacy of NSCLC patients. The main active ingredients include flavonoids and terpenoids, which can effectively exert antitumor effects. SFI could not only inhibit tumor cell proliferation and cell migration/invasion but also regulate the cell cycle and promote tumor cell apoptosis. In NSCLC, SFI could enhance the transcription level of the CHOP gene, thereby upregulating the expression of the proapoptotic proteins Bax and caspase 3, and inhibiting the expression of the antiapoptotic protein Bcl-2. SFI hindered the growth of mouse NSCLC xenografts in vivo. CONCLUSIONS: SFI hindered tumor progression and might promote apoptosis by increasing the expression of Bax, caspase 3 and decreasing the level of Bcl-2 in NSCLC.

RESUMO

OBJECTIVE: To observe the effect of Shenqi Chongcao (SQCC) Formula on the ASS1/src/STAT3 signaling pathway in a rat model of lung fibrosis and explore its therapeutic mechanism. METHODS: A total of 120 male SD rats were divided equally into 5 groups, including a blank control group with saline treatment and 4 groups of rat models of idiopathic pulmonary fibrosis induced by intratracheal instillation of bleomycin. One day after modeling, the rat models were treated with daily gavage of 10 mL/kg saline, SQCC decoction (0.423 g/kg), pirfenidone (10 mL/kg), or intraperitoneal injection of arginine deiminase (ADI; 2.25 mg/kg, every 3 days) for 28 days. After the treatments, the lung tissues of the rats were collected for calculating the lung/body weight ratio, observing histopathology using HE and Masson staining, and analyzing the inflammatory cells in BALF using Giemsa staining. Serum chemokine ligand 2 (CCL2) and transforming growth factor-ß1 (TGF-ß1) levels were measured with ELISA. The protein expressions of src, p-srcTry529, STAT3, and p-STAT3Try705 and the mRNA expressions of ASS1, src and STAT3 in the lung tissues were detected using Western blotting and RT-qPCR. RESULTS: The neutrophil, macrophage and lymphocyte counts and serum levels of CCL2 and TGF-ß1 were significantly lower in SQCC, pirfenidone and ADI treatment groups than in the model group at each time point of measurement (P < 0.05). P-srcTry529 and p-STAT3Try705 protein expression levels and ASS1, src, and STAT3 mRNA in the lung tissues were also significantly lower in the 3 treatment groups than in the model group (P < 0.05). CONCLUSION: SQCC Formula can alleviate lung fibrosis in rats possibly by activating the ASS1/src/STAT3 signaling pathway in the lung tissues.

RESUMO

Objective: This study aimed to evaluate the cost-effectiveness of two Chinese patent medicines, including Kang Ai injection and Shenqi Fuzheng injection with each combined with platinum-based chemotherapy as the first-line treatment for patients with advanced non-small cell lung cancer (NSCLC) in China. Methods: From Chinese healthcare system perspective, a three state Markov model with a cycle of 3 weeks and a 10-year horizon was constructed to derive the incremental cost-effectiveness ratio (ICER). Since only individual patient data of progression-free survival (PFS) of Kang Ai injection group can be obtained, we extrapolated median overall survival (mOS) of Kang Ai injection group and median progression-free survival (mPFS) and mOS of Shenqi Fuzheng injection group based on published literature and methods. Then survival curves were estimated by the method of declining exponential approximation of life expectancy (DEALE), which is based on the assumption that survival follows a declining exponential function. We performed one-way sensitivity analysis and probabilistic sensitivity analysis to test the robustness. Additionally, a scenario analysis was adopted to investigate the impact of using best-fitting distribution for PFS curve of Kang Ai injection group on the economic conclusion. Results: The base-case result indicated that Kang Ai injection group provided 0.217 incremental quality-adjusted life years (QALYs) at an incremental cost of $103.38 compared with Shenqi Fuzheng injection group. The ICER was $476.41/QALY, which was much lower than the willingness to pay threshold of one time the GDP per capita of China in 2022 ($12,070/QALY). Deterministic sensitivity analysis result showed that ICER was most sensitive to the changes in odds ratio (OR) value. The probabilistic sensitivity analysis confirmed the robustness of base-case analysis results. The scenario analysis result showed that by using Log-Normal distribution to fit the PFS curve of Kang Ai injection group and shortening the time horizon to 5 years, the ICER was $4,081.83/QALY, which was still much lower than the willingness to pay threshold. Conclusion: Kang Ai injection combined with platinum-based chemotherapy appeared to be more cost-effective for the treatment of advanced NSCLC than Shenqi Fuzheng injection combined with platinum-based chemotherapy.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: In the clinic, Shenqi Fuzheng Injection (SFI) is used as an adjuvant for cancer chemotherapy. However, the molecular mechanism is unclear. AIM OF THE STUDY: We screened potential targets of SFI action on gliomas by network pharmacology and performed experiments to validate possible molecular mechanisms against gliomas. MATERIALS AND METHODS: We consulted relevant reports on the SFI and glioma incidence from PubMed and Web of Science and focused on the mechanism through which the SFI inhibits glioma. According to the literature, two primary SFI components-Codonopsis pilosula (Franch.) Nannf. and Astragalus membranaceus (Fisch.) Bunge-have been found. All plant names have been sourced from "The Plant List" (www.theplantlist.org). The cell lines U87, T98G and GL261 were used in this study. The inhibitory effects of SFI on glioma cells U87 and T98G were detected by CCK-8 assay, EdU, plate cloning assay, scratch assay, Transwell assay, immunofluorescence, flow cytometry and Western blot. A subcutaneous tumor model of C57BL/6 mice was constructed using GL261 cells, and the SFI was evaluated by HE staining and immunohistochemistry. The targets of glioma and the SFI were screened using network pharmacology. RESULTS: A total of 110 targets were enriched, and a total of 26 major active components in the SFI were investigated. There were a total of 3,343 targets for gliomas, of which 79 targets were shared between the SFI and glioma tissues. SFI successfully prevented proliferation and caused cellular S-phase blockage in U87 and T98G cells, thus decreasing their growth. Furthermore, SFI suppressed cell migration by downregulating EMT marker expression. According to the results of the in vivo tests, the SFI dramatically decreased the development of tumors in a transplanted tumour model. Network pharmacological studies revealed that the SRC/PI3K/AKT signaling pathway may be the pathway through which SFI exerts its anti-glioma effects. CONCLUSIONS: The findings revealed that the SRC/PI3K/AKT signaling pathway may be involved in the mechanism through which SFI inhibits the proliferation and migration of glioma cells.

RESUMO

BACKGROUND: Cerebral microcirculation disturbance manifested by decrease of cerebral blood flow (CBF) is one of early features of Alzheimer's disease (AD). Shenqi Yizhi prescription (SQYZ) is widely used in the treatment of AD. However, the effect of SQYZ on the early feature of AD is not clarified. PURPOSE: To explore the effect and mechanism of SQYZ on AD-like behavior from the perspective of early pathological features of AD. METHODS: The fingerprint of SQYZ was established by ultra-high-performance liquid chromatograph. The improvement effect of SQYZ on Aß1-42 Oligomer (AßO)-induced AD-like behavior of mice was evaluated by behavioral test. The changes of CBF were detected by laser doppler meter and laser speckle imaging. The pathological changes of the hippocampus were observed by HE staining and transmission electron microscope. The expressions of intercellular communication molecules were detected by western blotting or immunofluorescence staining. The content of platelet-derived growth factor-BB (PDGF-BB) was detected by ELISA. Finally, the core components of SQYZ were docked with platelet-derived growth factor receptor beta (PDGFRß) using AutoDock Vina software. RESULTS: The similarity of the components in SQYZ extracted from different batches of medicinal materials was higher than 0.9. SQYZ administration could improve AßO-induced memory impairment and CBF reduction. Compared with the sham group, the number of neurons in the hippocampi of AßO group was significantly reduced, and the microvessels were shrunken and deformed. By contrary, SQYZ administration mitigated those pathological changes. Compared with the sham mice, the expressions of CD31, N-cadherin, PDGFRß, glial fibrillary acidic protein, phosphorylation of focal adhesion kinase, integrin ß1, and integrin α5 in the hippocampi of AßO mice were significantly increased. However, SQYZ administration significantly reduced AßO-induced expression of those proteins. Interestingly, the effect of PDGFRß inhibitor, sunitinib demonstrated a consistent modulating effect as SQYZ. Finally, the brain-entering components of SQYZ, including ginsenoside Rg5, coptisine, cryptotanshinone, dihydrotanshinone IIA, stigmasterol, and tanshinone IIA had high binding force with PDGFRß, implicating PDGFRß as a potential target for SQYZ. CONCLUSIONS: Our data indicate that SQYZ improves CBF in AßO-triggered AD-like mice through inhibiting brain pericyte contractility, indicating the treatment potential of SQYZ for AD at the early stage.

RESUMO

BACKGROUND: Research on the imbalance of proopiomelanocortin (POMC)/agouti-related protein (AgRP) neurons in the hypothalamus holds potential insights into the pathophysiology of diabetes. Jinkui Shenqi pills (JSP), a prevalent traditional Chinese medicine, regulate hypothalamic function and treat diabetes. PURPOSE: To investigate the hypoglycemic effect of JSP and explore the probable mechanism in treating diabetes. METHODS: A type 2 diabetes mouse model was used to investigate the pharmacodynamics of JSP. The glucose-lowering efficacy of JSP was assessed through various metrics including body weight, food consumption, fasting blood glucose (FBG), serum insulin levels, and an oral glucose tolerance test (OGTT). To elucidate the modulatory effects of JSP on hypothalamic mechanisms, we quantified the expression and activity of POMC and AgRP and assessed the insulin-mediated phosphoinositide 3-kinase (PI3K)/protein kinase A (AKT)/forkhead box O1 (FOXO1) pathway in diabetic mice via western blotting and immunohistochemistry. Additionally, primary hypothalamic neurons were exposed to high glucose and palmitic acid levels to induce insulin resistance, and the influence of JSP on POMC/AgRP protein expression and activation was evaluated by PI3K protein inhibition using western blotting and immunofluorescence. RESULTS: Medium- and high-dose JSP treatment effectively inhibited appetite, resulting in a steady declining trend in body weight, FBG, and OGTT results in diabetic mice (p < 0.05). These JSP groups also had significantly increased insulin levels (p < 0.05). Importantly, the medium-dose group exhibited notable protection of hypothalamic neuronal and synaptic structures, leading to augmentation of dendritic length and branching (p < 0.05). Furthermore, low-, medium-, and high-dose JSP groups exhibited increased phosphorylated (p) INSR, PI3K, pPI3K, AKT, and pAKT expression, as well as decreased FOXO1 and increased pFOXO1 expression, indicating improved hypothalamic insulin resistance in diabetic mice (p < 0.05). Treatment with 10% JSP-enriched serum produced a marked elevation of both expression and activation of POMC (p < 0.05), with a concurrent reduction in AgRP expression and activation within primary hypothalamic neurons (p < 0.05). Intriguingly, these effects could be attributed to the regulatory dynamics of PI3K activity. CONCLUSION: Our findings suggest that JSP can ameliorate diabetes by regulating POMC/AgRP expression and activity. The insulin-mediated PI3K/AKT/FOXO1 pathway plays an important regulatory role in this intricate process.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Jin-Gui-Shen-Qi Wan (JGSQW) is a traditional Chinese medicine formula that has been traditionally used to alleviate urinary system ailments such as frequent urination and polyuria. Clinical studies have indicated that when combined with hypoglycaemic drugs, JGSQW exhibits a synergistic effect and can improve diabetic nephropathy (DN), yet its underlying mechanism and targets remain unclear. AIM OF THE STUDY: This study aims to investigate the therapeutic efficacy of JGSQW and its underlying mechanisms using a DN db/db mouse model. MATERIALS AND METHODS: Ultrahigh-performance liquid chromatography coupled with mass spectrometry was utilized to analyse the primary active compounds, blood levels, and pharmacokinetics of JGSQW. Additionally, the therapeutic effects of JGSQW and metformin on blood glucose levels, lipid levels, renal function, and renal pathology in diabetic nephropathy mice were investigated using a db/db mouse model. Proteomic analysis was carried out to identify the primary target of JGSQW in treating DN. The mechanism of action was verified by western blotting, immunohistochemistry, and immunofluorescence. Then, molecular docking and molecular dynamics, transfection, drug affinity responsive target stability (DARTS) assay and cell thermal migration assay (CETSA) further validated the targeted binding effect. RESULTS: JGSQW combined with metformin significantly improved the blood glucose levels, blood lipids, renal function, and renal pathology of DN mice. JGSQW mainly exerted its therapeutic effect on DN by targeting major histocompatibility complex class II (MHC class II) molecules. Immunohistochemistry results showed that JGSQW inhibited the expression of collagen I, fibronectin, and alpha smooth muscle actin (α-SMA) expression. Immunofluorescence and Western blot results showed that JGSQW inhibited the expression of H2-Ab1 and H2-Aa, which are MHC class II molecules, thereby suppressing CD4+ T-cell infiltration and improving diabetic kidney fibrosis. The binding ability of paeoniflorin to H2-Aa was predicted and verified by molecular, DARTS, and CETSA assays. Treatment with 80 µM paeoniflorin effectively alleviated high glucose-induced injury in the MPC-5 injury model. H2-Aa was overexpressed at this model concentration, and Western blotting further confirmed that paeoniflorin reduced glomerular podocyte fibrosis by regulating H2-Aa. CONCLUSIONS: JGSQW combined with metformin may have a synergistic effect to alleviates renal fibrosis in diabetic nephropathy by downregulating immune complex MHC class II molecules and attenuating the antigen presentation effect of MHC class II on CD4.

RESUMO

BACKGROUND: Energy deficiency is the characteristic of chemotherapy-induced cachexia (CIC) which is manifested by muscle wasting. glycolysis, tricarboxylic acid (TCA) cycle, and lipid metabolism are central to muscle bioenergy production, which is vulnerable to chemotherapy during cancer treatment. Recent investigations have spotlighted the potential of Shenqi Fuzheng injection (SQ), a Chinese proprietary medicine comprising Radix Codonopsis and Radix Astragali, in alleviating CIC. However, the specific effects of SQ on muscle energy metabolism remains less explored. PURPOSE AND METHODS: Here, we integrated transcriptomics, spatial metabolomics, gas chromatography-mass spectrometry targeted quantitative analysis, and transmission electron microscopy techniques, combined with Seahorse live-cell metabolic analysis to reveal the changes in genes and pathways related to energy metabolism in the CIC model and SQ's protective effects at molecular and functional levels. RESULTS: Our data showed that chemotherapeutic agents caused glycolysis imbalance, which further leads to metabolic derangements of TCA cycle intermediates. SQ maintained glycolysis balance by facilitating pyruvate fluxing to mitochondria for more efficient bioenergy production, which involved a dual effect on promoting functions of mitochondrial pyruvate dehydrogenase complexes and inhibiting lactate dehydrogenase for lactate production. As a result of the sustained pyruvate level achieved by SQ administration, glycolysis balance was maintained, which further led to the preservation of mitochondrial integrity and function of electron transport chain, thereby, ensuring the normal operation of the TCA cycle and the proper synthesis of adenosine triphosphate (ATP). The above results were further validated using the Seahorse live-cell assay. CONCLUSION: In conclusion, our study highlights SQ as a promising strategy for CIC management, emphasizing its ability to harmonize the homeostasis of the muscle bioenergetic profile. Beyond its therapeutic implications, this study also offers a novel perspective for the development of innovative treatments in the realm of herbal medicine.

RESUMO

Shenqi-Tiaoshen formula (SQTSF) is a traditional Chinese medicine (TCM) prescription that has been employed in the treatment of chronic obstructive pulmonary disease (COPD). Clinical practice has demonstrated that SQTSF is an effective prescription for stable COPD. However, owing to the complexity of TCM prescription, there is a lack of in-depth understanding of the chemical components of SQTSF and its in vivo metabolism studies. In this study, a comprehensive analytical strategy based on ultra-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF/MS) was established to identify the chemical components, the absorbed components, and the metabolites of SQTSF given by gavage in rats, and analyze their dynamic changes. As a result, 86 chemical components of SQTSF were characterized, which were mainly categorized into flavonoids, saponins, organic acids, terpenoids, etc. Among them, 13 compounds were confirmed unambiguously by reference standards. Furthermore, 20 prototype components and 46 metabolites were detected in rat plasma at different time points. It was found that one prototype component and thirteen metabolites could be detected during the entire 24 h, indicating that these compounds were slowly eliminated and thus accumulated in vivo over a prolonged duration. Interestingly, the phenomenon that three prototype components and fourteen metabolites reappeared after a period of disappearance from the plasma was found. It was also observed that different prototype components may generate the same metabolite. The metabolic processes of SQTSF in rats mainly included oxidation, reduction, hydration, demethylation, deglycosylation, methylation, acetylation, glucuronidation, glutathionylation, and associated combination reactions. Overall, the present study identified the chemical components of SQTSF and their dynamic metabolic profile in rat plasma, which provided a systematic and applicable strategy for screening and characterization of the prototype components and metabolites of TCM compound preparations.

RESUMO

BACKGROUND: Breast cancer (BC) is the most frequent malignancy in the world. Chemotherapy (CT) is a common treatment for BC but is accompanied by toxicity and side effects. Shenqi Fuzheng Injection (SFI) is an adjuvant therapy with promising results in improving efficacy and reducing toxicity in clinical studies. This overview of systematic reviews and meta-analysis (SRs/MAs) aimed to summarize the benefits and evaluate the quality of evidence supporting SFI adjuvant as CT for BC. METHODS: A systematic search for SRs/MAs of randomized controlled trials (RCTs) on SFI treatment for BC was performed by searching PubMed, Web of Science, EMbase, Cochrane Library, CNKI, Wanfang, VIP, and SinoMed databases from inception to October 1, 2022. The quality of SRs/MAs was evaluated using AMSTAR-2, PRISMA 2020, ROBIS, and GRADE by two reviewers. The corrected covered area (CCA) was used to quantify the degree of duplication of the original SRs/MAs. Finally, quantitative analysis of RCTs was conducted using RevMan 5.4 software. This study was registered with PROSPERO, CRD42022377290. RESULTS: Six SRs/MAs including 61 RCTs with 5593 patients were included in this study. Studies were published between 2015 and 2019, the original RCTs ranged from 7-49, with sample sizes ranging from 336-1989. The quantitative meta-analysis found that adjuvant CT of SFI improved the clinical response rate (RR=1.37, 95% CI=1.28, 1.46; P<0.00001) and the KPS score (RR=1.66, 95% CI 1.54, 1.79, P<0.00001) of patients with BC. In terms of immune function, CD3+ (SMD=1.51, 95% CI 0.91, 2.10; P<0.00001), CD4+ (SMD=1.87, 95% CI 1.18, 2.56; P<0.00001), CD4+/CD8+ (SMD=0.86, 95% CI 0.48, 1.23; P<0.00001), and NK cell levels (SMD=0.94, 95% CI 0.63, 1.24; P<0.00001) in the adjuvant CT group SFI were better than those with CT alone. Adverse reactions following SFI adjuvant CT showed reduced incidence of leukopenia (RR=0.53, 95% CI 0.46, 0.62; P<0.00001) and gastrointestinal reactions (RR=0.48, 95% CI 0.39, 0.58; P<0.00001). However, the GRADE results showed 'very low' to 'moderate' evidence for the 42 outcomes, without high-quality evidence supporting them, limited mainly by deficiencies in the design of RCTs (42/42, 100.00%), inconsistency (19/42, 45.24%), publication bias (41/42, 97.62%), and inaccuracy (3/42, 7.14%). The unsatisfactory results of AMSTAR-2, PRISMA 2020, and ROBIS were limited to lack of registration of study protocols, explanation of inclusion basis of RCTs, description of funding sources for the included studies, incomplete search strategy and screening process, addressing heterogeneity and sensitivity, and reporting potential conflicts of interest. CONCLUSION: Adjuvant CT with SFI for BC had better benefits and a lower risk of adverse events. The methodology and quality of the evidence are generally low, highlighting a need of greater attention during study implementation. More objective and high-quality studies are needed to verify the efficacy of adjuvant CT with SFI in clinical decision-making for BC.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Lupus Nephritis (LN) is a serious complication of systemic lupus erythematosus (SLE). However, the treatment of lupus nephritis using traditional Chinese medicine remains controversial. AIM OF THE STUDY: To assess the efficacy and safety of Shenqi Dihuang decoction in the treatment of LN and review the clinical guidelines. MATERIALS AND METHODS: Six databases (China National Knowledge Infrastructure, Wanfang, PubMed, China Biology Medicine, the Cochrane Library, and Embase) were searched from their inception to September 10, 2022, for randomized controlled trials on the treatment of lupus nephritis using Shenqi Dihuang decoction. We conducted a meta-analysis of random effects using Review Manager 5.4 and assessed the certainty of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. RESULTS: A total of 15,790 citations were identified, from which 14 eligible randomized controlled trials that enrolled 1002 participants were selected for this systematic review. Low-to-moderate certainty of evidence indicated that when compared with Western medicine, Shenqi Dihuang decoction combined with Western medicine was associated with favorable effects on clinical efficacy (risk ratio (RR) = 1.25, 95% confidence interval (CI): 1.15-1.37), vascular endothelial growth factor (mean difference (MD) = -30.90, 95% CI: -40.18 to -21.63), serum level (MD = -4.81 µmol L-1, 95% CI: -17.14 to 7.53), complement C3 (MD = -0.14 g L-1, 95% CI: -0.23 to -0.04), erythrocyte sedimentation rate (MD = -11.87 mm h-1, 95% CI: -22.01 to -1.73), and SLE disease activity score (MD = -3.38, 95% CI: -4.15 to -2.61), and exhibited a lower risk of infection (RR = 0.2, 95% CI: 0.05-0.90), gastrointestinal reaction (RR = 0.47, 95% CI: 0.17-1.28), and insomnia (RR = 0.29, 95% CI: 0.09-0.92). CONCLUSIONS: This systematic review provides a potential reference for understanding the efficacy and safety of Shenqi Dihuang decoction combined with Western medicine for treating patients with lupus nephritis. However, owing to the limited quality of the studies included in this review, lack of mycophenolate mofetil control, and high heterogeneity among the included studies, the current findings should be interpreted with caution. Therefore, the efficacy and safety of Shenqi Dihuang decoction in patients with PN still require further verification through future high-quality clinical studies.

RESUMO

ObjectiveTo observe the clinical efficacy of modified Shenqi Pill (肾气丸) plus Tongdu Tiaoshen Acupuncture (通督调神针刺) in the treatment of neurogenic bladder after spinal cord injury of kidney-yang deficiency syndrome. MethodsForty-six patients were randomly divided into 23 cases each in the control group and the treatment group. Both groups were given conventional treatment, i.e. oral methylcobalamin tablets (0.5 mg each time, 3 times a day) and paraplegic conventional acupuncture (once a day, 6 consecutive days a week). The control group was given simple bladder function rehabilitation training on the basis of the conventional treatment; and the treatment group was given modified Shenqi Pill orally (1 dose a day, 150 ml each time, taken warmly in morning and evening) and Tongdu Tiaoshen Acupuncture (once a day, 6 consecutive days per week) in addition to what were given to the control group. The treatment course lasted for 4 weeks. The 24 h urination frequency, 24 h urine leakage frequency, 24 h single urine volume, bladder residual urine volume, international lower urinary tract symptom (LUTS) score, traditional Chinese medicine (TCM) syndrome score were compared between the two groups, and clinical effectiveness and TCM syndrome effectiveness were compared between the two groups after treatment. ResultsTwenty patients in each group were finally analyzed in this study. The number of 24 h urination, the number of 24 h urine leakage, bladder residual urine volume, LUTS score, and the TCM syndrome scores decreased after treatment in both groups, and the 24 h single urine volume increased (P<0.01); and much more improvement was found of each index in the treatment group than in the control group (P<0.05 or P<0.01). The total clinical effectiveness and TCM syndrome effectiveness in the treatment group was 85.00% (17/20) respectively, which were statistically significantly higher than 45.00% (the total clinical effectiveness, 9/20) and 60.00% (TCM syndrome effectiveness, 12/20) in the control group (P<0.01). ConclusionModified Shenqi Pill plus Tongdu Tiaoshen Acupuncture can signi-ficantly improve the clinical symptoms of neurogenic bladder patients after spinal cord injury of kidney-yang deficiency syndrome, having better effectiveness than simple bladder function rehabilitation training, and its mechanism may be related to the improvement of the injured nerve function innervating the bladder.

RESUMO

ObjectiveTo investigate the possible mechanism of Shenqi Jianxin Formula (参芪健心方) in the treatment of chronic heart failure (CHF) from the perspective of pyroptosis. MethodsFifty-two rats were randomly divided into sham operation group (n=8) and modeling group (n=44). In the modeling group, the anterior descending branch of the left coronary artery was ligated to construct CHF rat model. Forty successfully-modelled rats were randomly divided into model group, Entresto group, Shenqi Jianxin Formula group, MCC950 group and the combination group (Shenqi Jianxin Formula plus MCC950), with 8 rats in each group. In Shenqi Jianxin Formula group, 7.4 g/(kg·d) of Shenqi Jianxin Formula was given by gavage, while in Entresto group, 68 mg/(kg·d) of Entresto suspension was given by gavage; in MCC950 group, MCC950 was injected intraperitoneally with 10 mg/kg once every other day, and in the combination group, 7.4 g/(kg·d) of Shenqi Jianxin Formula was given by gavage, and MCC950 was injected intraperitoneally with 10 mg/kg once every other day; 10 ml/(kg·d) of saline was given by gavage in the sham operation group and the model group. After 3 weeks of continuous intervention, serum brain B-type natriuretic peptide (BNP), creatine kinase isoenzyme MB (CK-MB), interleukin 1β (IL-1β), and interleukin 18 (IL-18) levels were detected by ELISA; HE staining and MASSON staining were used to observe pathological changes in rat myocardium. Except for the Entresto group, western blot technique was used to detect the expression of NOD-like receptor protein 3 (NLRP3), caspase-1, and apoptosis-associated speck-like protein possessing a caspase-recruiting domain (ASC); RT-PCR was used to detect the expression of NLRP3 and caspase-1 mRNA. ResultsCompared with the sham operation group, HE staining of rats in the model group showed obvious myocardial injury, while MASSON staining showed increased area of collagen fibrosis, and serum BNP, CK-MB, IL-1β, IL-18, myocardial tissue NLRP3, caspase-1, ASC protein expression and NLRP3, caspase-1 mRNA expression were all elevated (P<0.05). Compared with those in the model group, cardiomyocyte injury of rats and collagen fibrosis area were reduced, and serum BNP, CK-MB, IL-1β, and IL-18 contents were all reduced in Shenqi Jianxin Formula group, Entresto group, MCC950 group, and the combination group; except for Entresto group, myocardial tissue NLRP3, caspase-1, ASC protein expression and NLRP3, caspase-1 mRNA expression were reduced in the remaining three medication group (P<0.05). Compared with Shenqi Jianxin Formula group, the MCC950 group and the combination group showed decreased serum IL-1β and IL-18 content, collagen fibrosis area, myocardial tissue NLPR3, caspase-1 protein expression, and caspase-1 mRNA expression, and decreased ASC and NLRP3 mRNA expression was shown in the combination group (P<0.05). Compared with MCC950 group, collagen fibrosis area was reduced, and serum IL-18 content, NLRP3, caspase-1 mRNA expression were reduced in the combination group (P<0.05). ConclusionShenqi Jianxin Formula can effectively improve the myocardial injury and heart failure in rats with CHF, and its mechanism may be related to the inhibition of cardiomyocyte pyroptosis through NLPR3/Caspase-1 pathway to reduce the level of intramyocardial inflammation. The combined use of MCC950 with Shenqi Jianxin Formula could more effectively inhibite myocardial pyroptosis, with better therapeutic result than single use of each part.

RESUMO

ObjectiveTo investigate the effect and mechanism of Shenqi Tangluo pill (SQTLP) on oxidative stress injury of skeletal muscle of type 2 diabetes mellitus (T2DM) mice based on nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1)/NAD(P)H quinone oxidoreductase 1 (NQO1) pathway. MethodA total of 60 7-week-old male db/db mice [specific pathogen-free (SPF) grade] were selected and fed for one week for adaption. They were divided into the model control group, SQTLP low-, medium- and high-dose (19, 38, and 76 g·kg-1) groups and metformin group (0.26 g·kg-1) by gavage. Each group consisted of 12 mice. Twelve male db/m mice of the same age were selected as the blank group. The intervention was implemented continuously for 8 weeks. Fasting blood glucose (FBG) was detected. Fasting serum insulin (FINS) levels were detected by enzyme-linked immunosorbent assay (ELISA), and the homeostasis model assessment-insulin resistance (HOMA-IR) index and the homeostasis model assessment-insulin sensitivity index (HOMA-ISI) were calculated. Oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were conducted. The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and the contents of malondialdehyde (MDA) and reduced nicotinamide adenine dinucleotide phosphate (NADPH) in skeletal muscle tissues were detected by biochemical kits. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in skeletal muscle tissues. The levels of reactive oxygen species (ROS) and 4-hydroxynonenal (4-HNE) in skeletal muscle tissue were detected by immunofluorescence (IF). The expression levels of Nrf2, HO-1, NQO1 and glutamate-cysteine ligase catalytic subunit (GCLC) proteins in skeletal muscle tissues were detected by Western blot. ResultCompared with those in the blank group, FBG, FINS and HOMA-IR in the model group were significantly increased (P<0.05), while HOMA-ISI was decreased (P<0.05). The results of OGTT and ITT showed that blood glucose was significantly increased at all time points (P<0.05), and glucose tolerance and insulin tolerance were significantly impaired. SOD and GSH-Px activities in skeletal muscle tissues were significantly decreased (P<0.05), and MDA and NADPH contents were significantly increased (P<0.05). In skeletal muscle tissues, the arrangement of muscle fibers was loose, the nucleus was disordered, and inflammatory cells were infiltrated. The expression levels of ROS and 4-HNE in skeletal muscle tissues were significantly increased (P<0.05). The protein expression levels of Nrf2, HO-1, NQO1 and GCLC in skeletal muscle tissues were significantly decreased (P<0.05). Compared with those in the model group, FBG, FINS and HOMA-IR in the metformin group were significantly decreased (P<0.05), while HOMA-ISI was increased (P<0.05). The results of OGTT and ITT showed that blood glucose in the metformin group was significantly decreased at all time points (P<0.05). The activities of SOD and GSH-Px in skeletal muscle tissues were significantly increased (P<0.05), while the contents of MDA and NADPH were significantly decreased (P<0.05). No obvious abnormality was found in the skeletal muscle tissue of the metformin group. The expressions of ROS and 4-HNE in skeletal muscle tissues were decreased (P<0.05). The protein expression levels of Nrf2, HO-1, NQO1 and GCLC in skeletal muscle tissues were significantly increased (P<0.05). Compared with those in the model group, FBG, FINS and HOMA-IR in the SQTLP medium- and high-dose groups were significantly decreased (P<0.05), while HOMA-ISI was increased (P<0.05). The results of OGTT and ITT showed that the glucose tolerance and insulin tolerance of mice were improved in each dose group of SQTLP. The GSH-Px activity in the SQTLP low-dose group was significantly increased (P<0.05), and the NADPH content was decreased (P<0.05). The activities of SOD and GSH-Px in the SQTLP medium- and high-dose groups were significantly increased (P<0.05), while the contents of MDA and NADPH were significantly decreased (P<0.05). The skeletal muscle tissue injury of mice in each dose group of SQTLP was ameliorated to different degrees. In the SQTLP medium- and high-dose groups, the expressions of ROS and 4-HNE were decreased (P<0.05), and the protein expression levels of Nrf2, HO-1, NQO1 and GCLC were significantly increased (P<0.05). Compared with those in the SQTLP low-dose group, FBG and HOMA-IR in the SQTLP high-dose group were significantly decreased (P<0.05), while HOMA-ISI was increased (P<0.05). The results of OGTT and ITT showed that the SQTLP high-dose group significantly improved the glucose tolerance and insulin tolerance of mice. The activities of SOD and GSH-Px in skeletal muscle tissues were significantly increased (P<0.05), while the contents of MDA and NADPH were significantly decreased (P<0.05). No obvious abnormality was found in the skeletal muscle tissue, the expressions of ROS and 4-HNE were decreased (P<0.05), and the protein expression levels of Nrf2, HO-1, NQO1 and GCLC were significantly increased (P<0.05) in the skeletal muscle tissue of the SQTLP high-dose group. ConclusionSQTLP can significantly improve IR in T2DM mice, and the mechanism is related to SQTLP activating the Nrf2/HO-1/NQO1 signaling pathway, promoting the expression of antioxidant enzymes, and thus improving the oxidative stress injury in the skeletal muscle.

RESUMO

BACKGROUND: Shenqi Compound (SQC) has been used in clinic for several decades in the prevention and treatment of diabetes and its complications. But this is merely a heritage of experience. The primary aim of this study is to scientifically validate the therapeutic effects of SQC on diabetic vascular calcification (DVC) in an animal model and, simultaneously, uncover its potential underlying mechanisms. METHOD: Spontaneous diabetic rat- Goto Kakizaki (GK) rats were selected for rat modeling. We meticulously designed three distinct groups: a control group, a model group, and an SQC treatment group to rigorously evaluate the influence of SQC. Utilizing a comprehensive approach that encompassed methods such as pathological staining, western blot analysis, qRT-PCR, and RNA sequencing, we thoroughly investigated the therapeutic advantages and the underlying mechanistic pathways associated with SQC in the treatment of DVC. RESULT: The findings from this investigation have unveiled the extraordinary efficacy of SQC treatment in significantly mitigating DVC. The underlying mechanisms driving this effect encompass multifaceted facets, including the restoration of aberrant glucose and lipid metabolism, the prevention of phenotypic transformation of vascular smooth muscle cells (VSMCs) into osteogenic-like states, the subsequent inhibition of cell apoptosis, the modulation of inflammation responses, the remodeling of the extracellular matrix (ECM), and the activation of the Hippo-YAP signaling pathway. Collectively, these mechanisms lead to the dissolution of deposited calcium salts, ultimately achieving the desired inhibition of DVC. CONCLUSION: Our study has provided compelling and robust evidence of the remarkable efficacy of SQC treatment in significantly reducing DVC. This reduction is attributed to a multifaceted interplay of mechanisms, each playing a crucial role in the observed therapeutic effects. Notably, our findings illuminate prospective directions for further research and potential clinical applications in the field of cardiovascular health.

RESUMO

This study aims to explore the effects of Shenqi Dihuang Decoction on high-glucose induced ferroptosis and the nuclear factor erythroid 2-related factor 2(Nrf2)/heme oxygenase-1(HO-1)/glutathione peroxidase 4(GPX4) axis in human renal tubular epithelial cells(HK-2) and to clarify the underlying mechanism. The cell injury model was established by exposing HK-2 to high glucose, and the Shenqi Dihuang Decoction-medicated serum was prepared. The optimal concentration and intervention time of Shenqi Dihuang Decoction were determined. HK-2 were divided into normal, high glucose, and low-, medium-, and high-dose Shenqi Dihuang Decoction groups. After interventions, the cell proliferation rate in each group was determined and the cell morphology and mitochondrial ultrastructure were observed. Then, the levels of intracellular reactive oxygen species(ROS), ferrous ion(Fe~(2+)), glutathione(GSH), and malondialdehyde(MDA) and the protein levels of Nrf2, HO-1, GPX4, and xCT were measured. The optimal concentration and intervention time of Shenqi Dihuang Decoction-medicated serum were determined to be 10% and 24 h, respectively. Compared with the high glucose group, high-dose Shenqi Dihuang Decoction promoted the proliferation of HK-2. The cells in the low-, medium-, and high-dose Shenqi Dihuang Decoction groups presented tight arrangement, an increased cell count, improved morphology from a spindle-fiber shape to a cobblestone shape, and improved morphology and structure of mitochondrial membrane and cristae, compared with those in the high glucose group. Meanwhile, all the doses of Shenqi Dihuang Decoction inhibited ROS elevation to mitigate the peroxidation damage, lowered the Fe~(2+) and MDA levels and elevated the GSH level to inhibit lipid peroxidation, and activated the antioxidant pathway to upregulate the protein levels of Nrf2, HO-1, xCT, and GPX4. In conclusion, Shenqi Dihuang Decoction-medicated serum can inhibit high-glucose induced ferroptosis of HK-2 in vitro, which involves the antioxidant effect and the activation of the Nrf2/HO-1/GPX4 pathway.
