Registration and characteristics of clinical trials on traditional Chinese medicine and natural medicines for endometriosis: a comprehensive analysis

ObjectiveTo investigate the characteristics of clinical trials on traditional Chinese medicine (TCM) or natural medicines for treating endometriosis, aiming to inform future clinical practice and the development of new effective drugs.MethodThe global clinical trial registration platform was searched to identify clinical trials investigating the efficacy of TCM/natural medicine in treating endometriosis. Relevant trials were selected based on stringent inclusion and exclusion criteria. Data entry was performed using Microsoft Excel, while data analysis was conducted using SPSS version 23.ResultsThe study encompassed 57 trials, of which ClinicalTrials.gov accounted for 18, ChiCTR for 3, ICRP for 15, and ChiDTR for 21 trials. The number of registrations showed a significant positive correlation with the years. Of the 57 clinical trials, 87.7% were randomized, 63.2% were blinded, 78.9% followed a parallel intervention model, and 56.1% had a sample size below 100. Regarding trial phases, 45.6% of clinical trials did not specify a phase, while Phase 3 and Phase 4 clinical trials accounted for 17.5%. Nine clinical trials involved drugs that are already on the market, including six Chinese patent medicines: Sanjie Zhentong Capsules, Honghua Ruyi Pills, Huayu Sanjie Enema Liquid, Kuntai Capsules, Wenjing Tang, and Xuefu Zhuyu Capsules. Outside China, Iran has the highest number of registrations for natural medicine treatments for endometriosis, with curcumin being the most registered natural medicine.ConclusionThe analysis reveals that clinical trials on TCM and natural remedies for endometriosis often utilize randomization; however, substantial deficiencies remain in blinding and sample size adequacy. These findings suggest that, despite growing interest in TCM and natural remedies, further methodological improvements are necessary to enhance the credibility of future studies. This research highlights the importance of rigorously designed clinical trials in verifying the safety and efficacy of these alternative therapies, which may influence future therapeutic approaches for managing endometriosis.

Bioinformatics Combined With Experimental Modeling to Study the Molecular Mechanism of Xuefu Zhuyu Decoction to Improve Erectile Dysfunction Associated With Asthma in Rats.

Asthma is associated with chronic systemic inflammation, and inflammatory factors can damage vascular endothelial cells, thus impairing erectile function (ED). Xuefu Zhuyu decoction (XFZYD) can inhibit inflammation and promote angiogenesis, which in turn improves asthma as well as ED, but its exact mechanism of action is not yet clear. This study investigates the mechanism underlying the beneficial effect of XFZYD on asthma-associated ED. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was used to analyze the constituents of XFZYD, and network pharmacology analysis was used to predict the target genes of XFZYD. Sprague-Dawley rats in the asthma model with erectile dysfunction were divided into the model, XFZYD low-, medium-, and high-dose group (3.09, 6.17, and 12.34 g/kg), with drug intervention for 8 weeks. We assessed the interleukin 6 (IL-6), vascular endothelial growth factor A (VEGFA), and tumor necrosis factor (TNF) protein levels in the penile tissue. We discovered that after treatment with XFZYD (3.09, 6.17, and 12.34 g/kg), the number of erections significantly increased (1.17 ± 0.41, 1.50 ± 0.55, and 1.67 ± 0.52), the density of endothelial cells in the corpus cavernosum of the penis increased, the expression level of IL-6 was reduced (7.5%, 21.2%, and 24.4%), the expression level of VEGFA was reduced (7.8%, 25%, and 28.4%), and the expression level of TNF was reduced (13.5%, 30.6%, and 32.4%). The in vivo experiments indicate that XFZYD may improve ED in asthma model rats by inhibiting inflammation and reducing vascular permeability. This study provides new insights into the mechanism of action of XFZYD in the treatment of asthma leading to ED.

Effect of Xuefu zhuyu oral liquid on tension-type headache: A randomized clinical trial

BackgroundTension-type headache (TTH) is the most common neurological disorder worldwide, incurring immense social and economic costs and affecting quality of life. However, due to adverse reactions and inadequate effectiveness, there is still an unmet need for treatment. Xuefu zhuyu oral liquid (XZOL) is a Chinese patent medicine widely used for TTH in China, but evidence of its efficacy remains scant. PurposeThe aim of this study was to assess the efficacy and safety of XZOL for TTH patients. MethodsThis multicenter, double-blind, randomized placebo-controlled trial enrolled 174 patients with TTH in six centers in China from March 2020 to October 2021. Patients were randomly assigned to receive XZOL or a matched placebo for 4weeks. The primary outcome was the change in the mean headache intensity as measured by a visual analogue scale (VAS) from baseline to the end of treatment (Week 4). Secondary outcomes were the change in VAS from baseline to Week 12, the area-under-the-headache curve (AUC), response rate, number of headache days, average headache duration, rescue medication use proportion, etc. ResultsOf the 174 patients who were randomized, 160 completed the study. There was no significant difference in the mean change in VAS from baseline to the end of treatment between the XZOL group and the placebo group (-0.29; (95 % CI:0.81 to 0.23; p = 0.279) in the full analysis set (FAS), while there were statistically significant results (-0.9; 95 % CI:1.47 to -0.33; p = 0.002) in the per-protocol set (PPS). There were no significant differences in any of the secondary outcomes. The incidence of adverse events was similar in the two groups. ConclusionXZOL may be an alternative option to relieve pain for TTH patients with high compliance in clinical practice. However, XZOL did not improve headache measurements in the FAS population.

Metabolomics integrated with network pharmacology of blood-entry constituents reveals the bioactive component of Xuefu Zhuyu decoction and its angiogenic effects in treating traumatic brain injury

BackgroundXuefu Zhuyu decoction (XFZYD) has been extensively utilized to treat traumatic brain injury (TBI). However, the bioactive compounds and the underlying mechanisms have not yet been elucidated.ObjectivesThis study aimed to investigate the bioactive constituents of XFYZD that are absorbed in the blood and the mechanisms in treating TBI.MethodsThe study presents an integrated strategy in three steps to investigate the material basis and pharmacological mechanisms of XFZYD. The first step involves: (1) performing metabolomics analysis of XFZYD to obtain the main functions and targets; (2) screening the blood-entry ingredients and targets of XFZYD from databases; (3) obtaining the potential components targeting the key functions by integrated analysis of metabolomics and network pharmacology. The second step involves screening pharmacological effects with active ingredients in vitro. In the third step, the effects of the top active compound were validated in vivo, and the mechanisms were explored by protein antagonist experiments.ResultsMetabolomics analysis revealed that XFZYD treated TBI mice mainly through affecting the functions of blood vessels. We screened 62 blood-entry ingredients of XFZYD by network pharmacology. Then, we focused on 39 blood-entry ingredients related to vascular genes enriched by XFZYD-responsive metabolites. Performing the natural products library, we verified that hydroxysafflor yellow A (HSYA), vanillin, ligustilide, paeoniflorin, and other substances promoted endothelial cell proliferation significantly compared to the control group. Among them, the efficacy of HSYA was superior. Further animal studies demonstrated that HSYA treatment alleviated neurological dysfunction in TBI mice by mNSS and foot fault test, and decreased neuronal damage by HE, nissl, and TUNEL staining. HSYA increased the density of cerebral microvessels, raised the expression of angiogenesis marker proteins VEGFA and CD34, and activated the PI3K/Akt/mTOR signaling pathway significantly. The angiogenic effects disappeared after the intervention of PI3K antagonist LY294002.ConclusionBy applying a novel strategy of integrating network pharmacology of constituents absorbed in blood with metabolomics, the research screened HSYA as one of the top bioactive constituents of XFZYD, which stimulates angiogenesis by activating the PI3K/Akt/mTOR signaling pathway after TBI.

Integrative analysis of the efficacy and pharmacological mechanism of Xuefu Zhuyu decoction in idiopathic pulmonary fibrosis via evidence-based medicine, bioinformatics, and experimental verification

ObjectiveWe used evidence-based medicine, bioinformatics and experimental verification to comprehensively analyze the efficacy and pharmacological mechanism of Xuefu Zhuyu decoction (XFZYD) in the treatment of idiopathic pulmonary fibrosis (IPF). MethodsMajor databases were retrieved for randomized controlled trials (RCTs) of XFZYD treating IPF to perform meta-analysis. Active ingredients and target genes of XFZYD were identified from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). IPF-related differentially expressed genes (DEGs) were identified from the Gene Expression Omnibus (GEO) database. The RGUI software was utilized for Gene Ontology (GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. The ingredient-target and protein-protein interaction (PPI) networks were achieved through Cytoscape software and the STRING database to identify the key compounds and target proteins. Molecular docking was performed using AutoDockTool and AutoDock Vina software. The effect between key compounds and target proteins was verified in animal experiments. ResultsSix RCTs were included for meta-analysis, which uncovered that the total effective rate of clinical efficacy was higher in the experimental group than control group. Then, 156 active ingredients and 254 target genes of XFZYD, and 1,566 IPF-related DEGs were identified. The intersection analysis identified 48 target genes correlating with 130 active ingredients of XFZYD treating IPF. GO functional enrichment, KEGG pathway enrichment, ingredient-target network and PPI network were achieved. Following the identification of key compounds and target proteins, we performed molecular docking. Ultimately, our research focused on the key compound quercetin for experimental validation to assess its interactions with two key target proteins, JUN and PTGS2. ConclusionThe effectiveness of XFZYD on IPF has been substantiated through evidence-based medicine. The pharmacological mechanism of XFZYD for IPF treatment involves a complex interplay of various compounds and targets, with quercetin exerting pronounced impacts on JUN and PTGS2 proteins.

Coronary heart disease: innovative understanding from traditional Chinese medicine and treatment by classic formulas

Coronary heart disease is a common cardiovascular disease, attacking about 11.4 million patients in China. With increasing prevalence and mortality year by year, coronary heart disease has become a major factor threatening human health and public health. Although primary and secondary prevention, intervention, coronary artery bypass grafting and other interventions have reduced the death rate, there are drug(aspirin) resistance, secondary nitroglycerin failure, post-intervention fatigue, chest tightness, and an-xiety, and complication with a high risk of bleeding, which have become the key clinical and scientific issues needed to be resolved. Coronary heart disease belongs to the category of chest impediment and heart pain in traditional Chinese medicine(TCM). The TCM etiology of this disease includes external contraction of cold, emotional disorders, constitutional insufficiency, physical weakness, and labor injury, which are closely related to sympathetic nerve activity, state of cardiac and psychological diseases, family history, and cardiovascular metabolic disorders in modern medicine. The TCM causes of coronary heart disease include Qi depression, phlegm turbidity, blood stasis, fire-heat, cold congealing, and healthy Qi deficiency, which are associated with emotional factors such as anxiety and depression, abnormal lipid metabolism, abnormalities in blood circulation and coagulation, inflammatory responses, hyperactive immune responses, and heart failure, chronic wasting disease, or aging, respectively. Accordingly, the patients with Qi depression should be treated with Chaihu Longgu Muli Decoction, and those with phlegm turbidity should be treated with Wendan Decoction and Gualou Xiebai Banxia Decoction. Xuefu Zhuyu Decoction and Guizhi Fuling Pills are recommended for blood stasis, Xiaoxianxiong Decoction and Sanhuang Xiexin Decoction for fire-heat, Zhishi Xiebai Guizhi Decoction for cold congealing, and Renshen Decoction for healthy Qi deficiency. Due to the changes in the spectrum of diseases from ancient to modern times as well as the differences in physical constitution, the key cause of coronary heart disease has evolved from the chest Yang deficiency and cold congealing to Qi depression, phlegm turbidity, phlegm combined with stasis, and fire-heat, showing a shift from cold to heat and from deficiency to excess. The combination of classic formulas presents a pattern. That is, the core formula-syndrome correspondence of a disease often fixedly appears with other formula-syndrome correspondence, which may be related to the development of the pathophysiological mechanism of the disease. In the clinical application of modern pharmacological results, the research team has formulated the clinical principle of pathogenesis corresponding to pathological changes and medicinal nature corresponding pharmacological effects. The modern pharmacological research on classic formulas is conducive to targeted treatment. Moreover, classic formulas help to ameliorate aspirin resistance, clopidogrel resistance, post-intervention anxiety, and high risk of bleeding and address the lack of effective blockade of critical lesions in the coronary artery and the progression of post-infarction heart failure. The innovative understanding of the etiology and pathogenesis of co-ronary heart disease helps to improve the clinical efficacy of TCM and the clinical system for treating coronary heart disease with classic formulas.

Xuefu Zhuyu decoction alleviates deep vein thrombosis through inhibiting the activation of platelets and neutrophils via sirtuin 1/nuclear factor kappa-B pathway

Ethnopharmacological relevanceXuefu Zhuyu Decoction (XZD), a renowned traditional Chinese medicine prescription, is widely employed for the management of conditions characterized by qi-stagnation and blood stasis. Although its anti-thrombotic effect on deep vein thrombosis (DVT) patients has been clinically observed, the underlying mechanism remains largely unexplored. Aim of the studyOur aim was to investigate the mechanisms by which XZD exerted its effect on DVT. Materials and methodsThe ultra performance liquid chromatography (UPLC) technique was employed to evaluate quality of XZD. To examine the effect of XZD on DVT, a DVT rat model with inferior vena cava (IVC) stenosis was established. The 4D-label-free proteomics approach was then utilized to uncover the possible mechanisms of XZD against DVT. Based on proteomics, citrullinated histone H3 (CitH3), along with serum levels of tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) were observed the inhibitory activity of XZD on neutrophil activation. Subsequently, the marker of platelet activation, specifically glycoprotein IIb (CD41) and glycoprotein IIIa (CD61), were assessed along with the secretion of von Willebrand factor (vWF) to investigate the inhibitory activity of XZD on platelet activation. Finally, we explored the impact of XZD on the sirtuin 1 (SIRT1)/nuclear factor kappa-B (NF-κB) pathway, which was associated with the activation of platelets and neutrophils. ResultsEight distinct components were identified for the quality control of XZD. XZD effectively reduced thrombus weight and length in DVT rats, without affecting the coagulation function or hematological parameters in the systemic circulation. Proteomics analysis revealed that XZD alleviated DVT by inhibiting the activation of platelets and neutrophils. The protein expression of CitH3, along with serum levels of TNF-α and IL-1β, were reduced in XZD-treated DVT rats. Similarly, protein expressions of CD41 and CD61, along with the release of vWF, were markedly down-regulated in XZD-treated DVT rats. Finally, treatment with XZD resulted in an up-regulation of SIRT1 protein expression and a down-regulation of both acetylated NF-κB/p65 and phosphorylated NF-κB/p65 protein expressions in endothelium. ConclusionsXZD alleviates DVT by inhibiting the activation of platelets and neutrophils at the injured endothelium via the regulation of SIRT1/NF-κB pathway.

Clinical intervention effect of Xuefu Zhuyu decoction on chronic heart failure complicated with depression

BACKGROUND The diagnosis and treatment of depression in patients with chronic heart failure (CHF) is challenging, with no ideal treatment at present. AIM To analyze the clinical intervention effect of Xuefu Zhuyu decoction (XFZYD) on CHF complicated with depression. METHODS The study cohort comprised 116 patients with CHF complicated with depression who received treatment from July 2020 to July 2023, of which 55 received Western medicine (control group) and 61 received XFZYD (research group). Data on clinical effectiveness, traditional Chinese medicine (TCM) syndrome score, cardiac function, negative emotions, and serum inflammatory factors, were collected for comparative analyses. RESULTS Compared with the control group, the research group had an evidently higher total effective rate. Furthermore, there were marked reductions in TCM symptom score, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, Self-Rating Depression Scale, Hamilton Depression Scale, high-sensitivity C-reactive protein, monocyte chemoattractant protein-1, and matrix metalloproteinase-9 in the research group after treatment, and these were lower than the corresponding values in the control group. Left ventricular ejection fraction was increased and higher in the research group compared with the control group after treatment. CONCLUSION Our findings conclusively proved that XFZYD was considerably superior to Western medicine for treating CHF complicated with depression because it significantly alleviated patients’ symptoms, improved cardiac function, relieved negative emotions, and reduced the levels of serum inflammatory factors.

Amygdalin ameliorates alopecia areata on C3H/HeJ mice by inhibiting inflammation through JAK2/STAT3 pathway

BackgroundEvidence has demonstrated that Chinese medicine formula Xuefu Zhuyu decoction can markedly promote the formation of new hair in patients and mice with alopecia areata (AA). Amygdalin is one of the active components of Xuefu Zhuyu decoction, but its therapeutic effects and the underlying mechanisms on AA remains largely unrevealed. PurposeTherefore, this study aims to investigate the therapeutic effects and to probe its molecular mechanisms of inflammation and immune regulation on AA model of C3H/HeJ mice. Study designThe C3H/HeJ female mice were divided into control, AA, rusolitinib (60 mg/kg), and amygdalin groups (60, 90, and 120 mg/kg, 0.2 ml/10 g, i.g.). MethodsThe optical microscope was used to observe the feature of the local skin, and the number of lanugo and terminal hair. H&E staining was performed to determine the degree of pathological damage to the skin. ELISA was performed to detect levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in mice serum. Flow cytometry was carried out to analyze the CD4+CD25+FOXP3+, CD4+ and CD8+ of skin tissue. And the levels of CD4+ and CD8+, p-JAK/JAK2, p-STAT3/STAT, and SOCS3 were detected by immunohistochemistry. Western blot and qRT-PCR were employed to examine the expression levels of IL-6, TNF-α, IFN-γ, JAK2, p-JAK, STAT, p-STAT3 and SOCS3 proteins and genes in skin tissues. ResultsCompared with AA group, amygdalin immensely increased the number of vellus hairs and decreased the number of terminal hairs determined by skin microscopy and H&E staining. ELISA, Western blot and qRT-PCR data showed that the levels of IL-6, TNF-α and IFN-γ in serum and skin tissues of AA mice were significantly increased, while amygdalin administration dramatically restrained the contents of the three pro-inflammatory factors. Flow cytometry and immunohistochemistry hinted that amygdalin observably enhanced the number of CD4+CD25+FOXP3+ and CD4+ cells, while inhibited the number of CD8+ positive cells in mice with AA. Moreover, amygdalin signally reduced JAK2/STAT3 pathway-related protein and gene levels in AA mice. ConclusionAmygdalin could inhibit inflammatory response and improve immune function in the treatment of AA. The underlying molecular mechanism may be related to inhibition of JAK2/STAT3 pathway.

Transcriptomic analysis reveals the critical role of chemokine signaling in the anti-atherosclerosis effect of Xuefu Zhuyu decoction

Ethnopharmacological relevanceThe process of atherosclerosis (AS) is complicated. Transcriptomics technology can assist in discovering the underlying mechanisms and exploring the key targets of Traditional Chinese Medicine (TCM) against atherosclerosis. AimThis study aimed to investigate targets and signaling pathways significantly related to AS and the potential intervention targets of Xuefu Zhuyu decoction by transcriptomics. Materials and methodsAS models were established by subjecting ApoE-/-mice to an 8-week high-fat diet. Structural changes and plaque formation in the aortic root were observed using hematoxylin-eosin staining (HE staining), while Oil Red O staining was employed to visualize lipid deposition within the aortic root plaque. Movat staining and immunohistochemical staining were conducted to examine the components present in the aortic root plaque. Macrophage content within the plaque was observed through immunofluorescence. Additionally, mRNA sequencing was performed on aortic tissues to identify differentially expressed genes. Enrichment analysis was performed using GO and KEGG analysis. Visualization of the protein-protein interaction (PPI) network was achieved using Cytoscape 3.7.1 and STRING. Western blotting (WB) was employed to assess the protein expression of major differentially expressed genes in the aortic tissue. The drug freeze-dried powder of Xuefu Zhuyu decoction was prepared and the RAW264.7 cells were induced by lipopolysaccharide (LPS) to build an in vitro model. Real-time quantitative PCR was employed to measure the mRNA expression of major differential genes. ResultsAfter ApoE-/- mice were fed with an 8-week high-fat diet, observable changes included the thinning of the aortic root wall, the accumulation of foam cells within the plaque, and the formation of cholesterol crystals in the model group. Treatment with Xuefu Zhuyu (XFZY) decoction for 12 weeks significantly reduced the lipid deposition and the number of macrophages (P < 0.05) and significantly increased the collagen content within the plaque (P < 0.01). Enrichment analysis revealed a high enrichment of the Cytokine-cytokine receptor interaction pathway and Chemokine signaling pathway. Noteworthy genes involved in this response included Ccl12, Ccl22, Cx3cr1, Ccr7, Ccr2, Tnfrsf25, and Gdf5. Xuefu Zhuyu decoction significantly downregulated the expression of CX3CL1 and CX3CR1 (P < 0.05) and upregulated the expression of GDF5 (P < 0.01). Compared with control group, in cell models, the mRNA expressions of Ccl12, Ccl22, and Ccr2 were significantly upregulated (P < 0.05 or P < 0.01). Xuefu Zhuyu decoction significantly downregulated the expression of Ccl12, Ccl22, Cx3cr1, Ccr7 and Ccr2 (P < 0.05 or P < 0.01). ConclusionXuefu Zhuyu decoction demonstrates effective regulation of plaque components, retarding plaque progression and preserving plaque stability by modulating lipid metabolism and inflammatory responses. Subsequent transcriptome analysis identified the Cytokine-cytokine receptor interaction and Chemokine signaling pathway as potential key pathways for the therapeutic effects of Xuefu Zhuyu decoction. This insight not only provides crucial avenues for further exploration into the mechanisms underlying Xuefu Zhuyu decoction but also offers valuable perspectives and hypotheses for enhancing disease prevention and treatment strategies.

Xuefu Zhuyu decoction promotes synaptic plasticity by targeting miR-191a-5p/BDNF-TrkB axis in severe traumatic brain injury

BackgroundXuefu Zhuyu decoction (XFZYD) is a traditional Chinese herbal formula known for its ability to eliminate blood stasis and improve blood circulation, providing neuroprotection against severe traumatic brain injury (sTBI). However, the underlying mechanism is still unclear. PurposeWe aim to investigate the neuroprotective effects of XFZYD in sTBI from a novel mechanistic perspective of miRNA-mRNA. Additionally, we sought to elucidate a potential specific mechanism by integrating transcriptomics, bioinformatics, and conducting both in vitro and in vivo experiments. MethodsThe sTBI rat model was established, and the rats were treated with XFZYD for 14 days. The neuroprotective effects of XFZYD were evaluated using a modified neurological severity score, hematoxylin and eosin staining, as well as Nissl staining. The anti-inflammatory effects of XFZYD were explored using quantitative real-time PCR (qRT-PCR), Western blot analysis, and immunofluorescence. Next, miRNA sequencing of the hippocampus was performed to determine which miRNAs were differentially expressed. Subsequently, qRT-PCR was used to validate the differentially expressed miRNAs. Target core mRNAs were determined using various methods, including miRNA prediction targets, mRNA sequencing, miRNA-mRNA network, and protein-protein interaction (PPI) analysis. The miRNA/mRNA regulatory axis were verified through qRT-PCR or Western blot analysis. Finally, morphological changes in the neural synapses were observed using transmission electron microscopy and immunofluorescence. ResultsXFZYD exhibited significant neuroprotective and anti-inflammatory effects on subacute sTBI rats' hippocampus. The analyses of miRNA/mRNA sequences combined with the PPI network revealed that the therapeutic effects of XFZYD on sTBI were associated with the regulation of the rno-miR-191a-5p/BDNF axis. Subsequently, qRT-PCR and Western blot analysis confirmed XFZYD reversed the decrease of BDNF and TrkB in the hippocampus caused by sTBI. Additionally, XFZYD treatment potentially increased the number of synaptic connections, and the expression of the synapse-related protein PSD95, axon-related protein GAP43 and neuron-specific protein TUBB3. ConclusionsXFZYD exerts neuroprotective effects by promoting hippocampal synaptic remodeling and improving cognition during the subacute phase of sTBI through downregulating of rno-miR-191a-5p/BDNF axis, further activating BDNF-TrkB signaling.

Mechanisms of Xuefu Zhuyu Tang in the Treatment of Diabetic Erectile Dysfunction in Rats Through the Regulation of Vascular Endothelial Function by CaSR/PLC/PKC and MEK/ERK/RSK Pathways.

Xuefu zhuyu Tang (XFZYT) is a classic formula used for promoting blood circulation and resolving blood stasis in Traditional Chinese Medicine. Clinical data have indicated that XFZYT plays a significant therapeutic role in diabetes-induced erectile dysfunction (DIED) disease, but the underlying mechanism remains elusive. Male Sprague-Dawley (SD) rats were randomly categorized into normal, model, and treatment groups. The diabetic rat model was established via intraperitoneal injection of streptozotocin. DIED rats were screened using apomorphine, and the number of erections was measured after 8 weeks of XFZYT treatment. Serum nitric oxide (NO) and endothelin-1 levels as well as penile tissue structure alterations were assessed by hematoxylin-eosin staining and electron microscopy. CaSR/PLC/PKC and MEK/ERK/RSK pathway-related proteins in the penile tissue were detected by western blotting (WB) analysis and polymerase chain reaction (PCR). Compared with the blank group, the model group rats showed a significant decrease in weight and erectile function. The pathological damage in the penile tissues of the model rats was indicated by a significantly decreased serum NO level and an increased endothelin-1 content. After treatment with XFZYT, the protein expression of CaSR, PLCβ1, PKCβ, MEK1, ERK1, and RSK1 in the penile tissue was significantly increased. Overall, the treatment group showed significant improvements in the evaluated indexes. In conclusion, this study revealed that XFZYT improves erectile function in diabetic rats, and the underlying mechanism might be linked with the regulation of CaSR/PLC/PKC and related molecules of the MEK/ERK/RSK pathway, which promotes the vascular endothelial diastolic effect.

Screening of anticoagulant active components in Xuefu Zhuyu decoction via affinity-ultrafiltration coupled with mass spectrometry.

This study aimed to establish an effective affinity-ultrafiltration coupled with mass spectrometry (AUF-MS) method to rapidly screen the active components of antithrombin in Xuefu Zhuyu decoction (XFZYD). The HPLC fingerprint of different batches of XFZYD was established to verify the stability of the compound ingredients. AUF-MS was established for the rapid screening of the active ingredients in XFZYD. Eight active ingredients were screened using AUF-MS: oxypaeoniflorin, chlorogenic acid, amygdalin, isoliquiritin, neohesperidin, hesperidin, glycyrrhizic acid and chikusetsu saponin IVa. Simultaneously, the anticoagulant effect of the active ingredients was verified by performing in vivo and in vitro experiments. The results of this study indicate that AUF-MS can be used for high-throughput screening of active components of traditional Chinese medicine compounds, thus providing a basis for the discovery of thrombin inhibitors and promoting the research progress of antithrombotic drugs. The compounds screened from XFZYD showed an inhibitory effect against thrombin and a certain antithrombotic effect.

Efficacy and mechanism of Xuefu Zhuyu Decoction on model rats of coronary heart disease with heart blood stasis syndrome based on metabolomics

This study investigated the effects of Xuefu Zhuyu Decoction on myocardial metabolites in a rat model of coronary heart disease with heart blood stasis syndrome and explored the therapeutic mechanism of blood circulation-promoting and blood stasis-removing therapy. SD rats were randomly divided into a sham operation group, a model group, a Xuefu Zhuyu Decoction group(14.04 g·kg~(-1)), and a trimetazidine group(5.4 mg·kg~(-1)). The sham operation group underwent thread insertion without ligation, while the other groups underwent coronary artery left anterior descending branch ligation to induce a model of coronary heart disease with heart blood stasis syndrome. Three days after modeling, drug intervention was performed, and samples were taken after 14 days of intervention. General conditions were observed, and electrocardiogram and cardiac ultrasound indices were measured. Hematoxylin-eosin(HE) staining and Masson staining were used to observe tissue pathological morphology. The enzyme linked immunosorbent assay(ELISA) was used to measure the levels of triglyceride(TG) and total cholesterol(TC) in the serum. Ultra high performance liquid chromatography-quantitative exactive-mass spectrometry(UHPLC-QE-MS) technology was used to screen differential metabolites in myocardial tissue and conduct metabolic pathway enrichment analysis. The results showed that Xuefu Zhuyu Decoction significantly improved the general condition of the model rats, reduced heart rate and ST segment elevation in the electrocardiogram, increased left ventricular ejection fraction(LVEF) and left ventricular fractional shortening(LVFS), and decreased left ventricular internal diameter in diastole(LVIDd) and left ventricular internal diameter in systole(LVIDs). HE staining and Masson staining showed that Xuefu Zhuyu Decoction effectively alleviated myocardial tissue structural disorders, inflammatory cell infiltration, and collagen fiber deposition in the model rats. ELISA results showed that Xuefu Zhuyu Decoction effectively regulated serum TG and TC levels in the model rats. There were significant differences in the metabolic phenotypes of myocardial samples in each group. Fourteen differential metabolites were identified in the Xuefu Zhuyu Decoction group, involving five metabolic pathways, including arginine and proline metabolism, glycerophospholipid metabolism, aminoacyl-tRNA biosynthesis, ether lipid metabolism, and alanine, aspartate, and glutamate metabolism. Xuefu Zhuyu Decoction improved cardiac function and myocardial structural damage in the rat model of coronary heart disease with heart blood stasis syndrome, and its biological mechanism involved the regulation of lipid metabolism, choline metabolism, amino acid metabolism, energy metabolism, and protein synthesis pathways.

Effectiveness and safety of traditional Chinese medicine for diabetic retinopathy: A systematic review and network meta-analysis of randomized clinical trials.

Diabetic retinopathy (DR) is currently recognized as one of the most serious diabetic microangiopathies and a major cause of adult blindness. Commonly used clinical approaches include etiological control, microvascular improvement, and surgical intervention, but they are ineffective and have many side effects. Oral Chinese medicine (OCM) has been used for thousands of years to treat DR and is still widely used today, but it is unclear which OCM is more effective for DR. To estimate relative effectiveness and safety profiles for different classes of OCMs for DR, and provide rankings of the available OCMs. The search time frame was from the creation of the database to January 2023. RevMan 5.3 and Stata 14.0 software were used to perform the systematic review and Network meta-analyses (NMA). A total of 107 studies and 9710 patients were included, including 4767 cases in the test group and 4973 cases in the control group. Based on previous studies and clinical reports, and combined with the recommendations of Chinese guidelines for the prevention and treatment of DR, 9 OCMs were finally included in this study, namely Compound Xueshuantong Capsules, Qiming Granules, Compound Danshen Dripping Pills, Hexue Mingmu Tablets (HXMM), Qiju Dihuang Pills (QJDH), Shuangdan Mingmu Capsules (SDMM), Danggui Buxue Decoction (DGBX), Xuefu Zhuyu Decoction and Buyang Huanwu Decoction. When these nine OCMs were analyzed in combination with conventional western medicine treatment (CT) compared with CT alone, the NMA results showed that HXMM + CT has better intervention effect on the overall efficacy of DR patients, HXMM + CT has better effect on improving patients' visual acuity, SDMM + CT has better effect on inhibiting vascular endothelial growth factor, DGBX + CT has better effect on reducing fundus hemorrhage area, HXMM + CT has better effect on reducing fasting blood glucose, and QJDH + CT has better effect on reducing glycated hemoglobin. When there are not enough clinical indicators for reference, SDMM + CT or HXMM + CT treatments can be chosen because they are effective for more indicators and demonstrate multidimensional efficacy. This study provides evidence that combining OCMs with CT leads to better outcomes in all aspects of DR compared to using CT alone. Based on the findings, we highly recommend the use of SDMM or HXMM for the treatment of DR. These two OCMs have demonstrated outstanding efficacy across multiple indicators.

Effectiveness and safety of Xuefu Zhuyu oral liquid on -stagnation and blood-stasis pattern in patients with stable angina, tension-type headache and primary dysmenorrhea: rationale and design of a master protocol.

We present the rationale and design of a master protocol study that clarifies the effectiveness and safety of Chinese herbal formulas on -stagnation and blood-stasis pattern (QBP). Three randomized controlled trials (RCTs) and real-world observational studies. Based on three registry cohorts of stable angina, tension-type headache and primary dysmenorrhea, patients with QBP will be enrolled in RCTs to receive either Xuefu Zhuyu (, XFZY) oral liquid or a placebo, while patients with non-QBP will be enrolled in the observational studies and experience follow-up. 1414 patients (RCTs: 574; observational studies: 840) will be recruited at seven centers in China over a 3-year period. The primary outcome is the visual analog scale of pain intensity. Adverse events will also be reported. The analysis will be undertaken separately in each sub-study, and then an overall analysis combining multiple subgroups will be performed to comprehensively investigate the effect of XFZY oral liquid. This study will provide high-quality evidence of XFZY oral liquid for QBP patients and show a paradigm of post-marketing evaluation of the effectiveness and safety for Chinese medicine following the notion of the pattern dominating different disease research models.
