[PMID: 39006289 PMCID: PMC11236642 DOI: 10.62347/ghov4912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Accepted: 05/24/2024] [Indexed: 07/16/2024]
Abstract
OBJECTIVE To explore the mechanism of Qigui-Yishen decoction in delaying renal fibrosis in mice by regulating thrombin regulatory protein (Thrombomodulin, TM) and plasminogen activator inhibitor-1 (PAI-1) based on network pharmacology. METHODS The active ingredients of Qigui Yishen decoction and their target molecules associated with chronic kidney disease (CKD) were retrieved from websites and databases, sorted out, and screened, and the possible targets of Qigui Yishen decoction for reducing CKD renal fibrosis were predicted and analyzed. Forty Institute of Cancer research (ICR) rats were used to establish a unilateral ureteral obstruction (UUO) model, and divided into several groups: sham operation group, model group, high concentration decoction group (1 g/mL), low concentration decoction group (0.46 g/mL), and benazepril group (0.1 g/mL). At the end of the experiment, the levels of serum creatinine (Scr) and blood urea nitrogen (BUN) were detected. Masson staining was used to observe changes in the renal interstitial fibrosis index. Immunohistochemistry and western blot were used to detect the expressions of TM, PAI-1, transforming growth factor-β1 (TGF-β1) and collagen I (Col I) in kidney tissues, and the differences between groups were compared. RESULTS Qigui Yishen decoction contains 42 effective ingredients such as sitosterol, mannitol, and quercetin, with 662 drug targets and 16154 disease targets. Analysis revealed 570 potential targets, including TM4SF19, PAIP1, TGF-β1, and Col I-AI. Compared to the sham operation group, all treatment groups exhibited increased Scr and BUN levels (P<0.05) and enhanced renal interstitial fibrosis (P<0.05) after UUO model establishment. Moreover, immunohistochemical results showed significant increases in PAI-1, TGF-β1, and Col I (all P<0.05), and a significant decrease in TM expression (P<0.05). Compared to the model group, the high concentration decoction group, low concentration decoction group and benazepril group had no significant difference in Scr and BUN values (P>0.05), but the renal interstitial fibrosis index was lower (P<0.05). Also, the relative expressions of PAI-1, TGF-β1 and Col I in the kidney tissue of mice were decreased, while the relative expression of TM was increased (P<0.05). CONCLUSION Qigi Yishen decoction has the characteristics of multiple components and multiple targets, and can play a role in delaying renal fibrosis by regulating the expression of PAI-1, TGF-β1, Col I, and TM.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 117:154913. [PMID: 37307737 DOI: 10.1016/j.phymed.2023.154913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 05/16/2023] [Accepted: 06/02/2023] [Indexed: 06/14/2023]
Abstract
BACKGROUND Immunoglobulin A nephropathy (IgAN), is the main cause of end-stage renal disease, that causes serious physical and psychological burden to patients worldwide. Some traditional treatment measures, such as blocking the renin-angiotensin-aldosterone system, controlling blood pressure, and following a low-protein diet, may not achieve satisfactory results. Therefore, more effective and safe therapies for IgAN are urgently needed. PURPOSE The aim of this review is to summarize the clinical efficacy of Chinese herbal medicines (CHMs) and their active ingredients in the treatment and management of IgAN based on the results of clinical trials, systematic reviews, and meta-analyses, to fully understand the advantages and perspectives of CHMs in the treatment of IgAN. STUDY DESIGN AND METHODS For this review, the following electronic databases were consulted: PubMed, ResearchGate, Science Direct, Web of Science, Chinese National Knowledge Infrastructure and Wanfang Data, "IgA nephropathy," "traditional Chinese medicine," "Chinese herbal medicine," "herb," "mechanism," "Meta-analysis," "systematic review," "RCT" and their combinations were the keywords to search the relevant literature. Data were collected from 1990 to 2022. RESULTS This review found that the active ingredients of CHMs commonly act on multiple signaling pathways in the clinical treatment of IgAN, mainly with antioxidant, anti-inflammatory and anti-fibrosis effects, and regulation of autophagy. CONCLUSION Compared with the single-target therapy of modern medicine, CHMs can regulate the corresponding pathways from the aspects of anti-inflammation, anti-oxidation, anti-fibrosis and autophagy to play a multi-target treatment of IgAN through syndrome differentiation and treatment, which has good clinical efficacy and can be used as the first choice or alternative therapy for IgAN treatment. This review provides evidence and research direction for a comprehensive clinical understanding of the protective effect of Chinese herbal medicine on IgAN.

Abstract
BACKGROUND IgA nephropathy (IgAN) is a common primary glomerular disease, and supplementing qi dispelling wind and activating blood is commonly used as a treatment method in Chinese medicine. However, the existing studies have small sample sizes. This study aimed to use a meta-analysis to explore the clinical efficacy of this method and to systematically introduce this effective treatment. METHODS We searched for randomized controlled trial studies on supplementing qi dispelling wind and activating blood circulation methods for IgAN indexed in the China National Knowledge Infrastructure, Wanfang Data, Chongqing VIP, SinoMed, PubMed, EMBASE, and Web of Science databases, which were interrogated from database inception to January 2022. Combining the inclusion and exclusion criteria to screen the literature, we included a total of 15 eligible studies; the quality of the included studies was evaluated using the risk of bias assessment tool of the Cochrane System Revies Manual 5.4. The outcome indexes were extracted, and a meta-analysis was performed using Review Manager 5.4 software. RESULTS Fifteen articles were included in this review. A meta-analysis of the results led to the conclusion that supplementing qi dispelling wind and activating blood circulation prescription has beneficial effects on the total effective rate [odds ratios = 3.95, 95% confidence interval (CI) 2.76-5.67], and can reduce 24-hour urinary protein quantity (mean deviation = -0.35, 95% CI -0.54 to -0.16) and serum creatinine (mean deviation = -15.41,95% CI -28.39 to -2.44) without impact normal level of alanine transaminase, hemoglobin, and serum albumin. CONCLUSIONS Supplementing qi dispelling wind and activating blood can significantly improve renal function and reduce 24-hour urinary protein quantity levels in patients with IgAN compared to the use of non-Chinese medicine treatment. This finding provides a rationale for using this method in the clinical treatment of IgAN.

Abstract
Objective Traditional Chinese medicine (TCM) has a long history in the treatment of Immunoglobulin A nephropathy (IgAN). A large number of animal experiments focused on the TCM treatment of IgAN are conducted every year. The evidence for these preclinical studies is not clear. This study summarized and evaluated the results of animal experiments on TCM treatment for IgAN. Methods We systematically searched animal studies from 6 databases from inception to August 30, 2022. We included Chinese studies from the key magazine of China technology. The quality of the included studies was evaluated with the SYRCLE animal experimental bias risk assessment tool and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results Out of 832 records identified in the initial search, 30 studies were selected. The results indicated that, compared with the control group, the TCM treatment group improved 24 h urine protein (24 h-UP) level (standardized mean difference (SMD) 3.57, 95% confidence interval (CI) 4.48 to 2.66, P < 0.001), urine red blood cell (U-RBC) (SMD 13.66, 95% CI 17.99 to 9.32, P < 0.001), serum creatinine (Scr) (mean difference (MD) 10.89, 95% CI 17.00 to 4.77, P < 0.001), blood urea nitrogen (BUN) (MD 2.44, 95% CI 3.42 to 1.47, P < 0.001), tumor necrosis factor-α (TNF-α) (MD 171.28 to 95% CI 323.68 to 18.88, P=0.03), transforming growth factor-β1 (TGF-β) (SMD 4.02, 95% CI 7.26 to 0.77, P=0.02), matrix metalloproteinase-9/tissue inhibitors of metalloproteinase-1(MMP-9/TIMP-1) (MD 0.03, 95% CI 0.00 to 0.06, P=0.02), nephrin mRNA (SMD 3.39, 95% CI 2.59 to 4.18, P < 0.001). However, there is no difference in albumin level (MD 1.10, 95% CI 0.06 to 2.26, P=0.06) and interleukin-6 (IL-6) (MD 170.77, 95% CI 365.3 to 23.75, P=0.09). Conclusions TCM can improve 24 h-UP, U-RBC, Scr, BUN, MMP-9/TIMP-1, TNF-α, TGF-β, and nephrin mRNA of IgAN animal models. Moreover, there is a need for rigorous reporting of preclinical research methodology, which is essential to support the quality of preclinical research. Registration.

Abstract
Objective It is not clear which Traditional Chinese Medicine- (TCM-) related elements affect primary IgA nephropathy (IgAN) progression. Here, we explored the risk factors, based on TCM syndrome elements, related to the prognosis of primary IgAN patients. Methods We analyzed patients with newly diagnosed, biopsy-proven IgAN at a single institution from December 2013 to September 2021. Basic clinical and pathological characteristics were assessed at the time of renal biopsy. The study endpoint was end-stage renal disease (ESRD: eGFR <15 ml/min per 1.73 m2, dialysis, or kidney transplantation) and/or eGFR decreased by >30% from baseline. Kaplan‒Meier survival analysis was used to explore the role of TCM syndrome elements in IgAN progression. Multivariate Cox regression analysis with adjustment for traditional risk factors was performed to explore TCM syndrome elements that may influence patient prognosis. The factors correlated with TCM syndrome elements in IgAN patients were further evaluated by logistic regression analysis. Results During a median follow-up of 22.0 months, 53 (12.5%) of the 423 included IgAN patients reached the study endpoint. The main IgAN disease location elements were the kidney, liver, and spleen. The main IgAN disease nature elements were Yin-deficiency and Qi-deficiency, dampness, Yang-deficiency, phlegm, and Blood-deficiency. Kaplan‒Meier analysis identified three disease locations (liver, spleen, and kidney) and four disease natures (Qi-deficiency, Yang-deficiency, phlegm, and dampness) as elements associated with poor renal survival in IgAN patients. In multivariate Cox regression analysis, baseline Yang-deficiency was an independent risk predictor of poor prognosis in primary IgAN patients (hazard ratio 2.338; 95% confidence interval [CI]: 1.208–4.525; P=0.012) after adjustment for traditional risk factors. Furthermore, logistic regression analysis identified being female (odds ratio [OR] 2.518; 95% CI: 1.538–4.122; P < 0.001), older age (OR 1.043; 95% CI: 1.022–1.065; P < 0.001), low hemoglobin levels (OR 0.984; 95% CI: 0.971–0.996; P=0.013), and cellular/fibrocellular crescents (OR 1.706; 95% CI: 1.068–2.728; P=0.026) as factors affecting Yang-deficiency in IgAN patients. Conclusions Yang-deficiency independently predicts the risk of poor prognosis in primary IgAN patients. Being female, older age, low hemoglobin levels, and cellular/fibrocellular crescents were independently associated with Yang-deficiency in IgAN patients.

Abstract
With the rapid development of high-throughput sequencing technology, approaches for assessing biological ingredients in Traditional Chinese Medicine (TCM) preparations have also advanced. Using a multi-barcode sequencing approach, all biological ingredients could be identified from TCM preparations in theory, as long as their DNA is present. The biological ingredients of several classical TCM preparations were analyzed successfully based on this approach in previous studies. However, the universality, sensitivity and reliability of this approach on a diverse set of TCM preparations remain unclear. In this study, we selected four representative TCM preparations, namely Bazhen Yimu Wan, Da Huoluo Wan, Niuhuang Jiangya Wan, and You Gui Wan, for concrete assessment of the multi-barcode sequencing approach. Based on ITS2 and trnL biomarkers, we have successfully detected the prescribed herbal materials (PHMs) in these representative TCM preparations (minimum sensitivity: 77.8%, maximum sensitivity: 100%). The results based on ITS2 have also shown higher reliability than trnL at species level, while their combination could provide higher sensitivity and reliability. The multi-barcode sequencing approach has shown good universality, sensitivity and reliability in decoding these four representative TCM preparations. In the omics big-data era, this work has undoubtedly made one step forward for applying multi-barcode sequencing approach in PHMs analysis of TCM preparation, towards better digitization and modernization of drug quality control.

Front Pharmacol 2021; 12:714584. [PMID: 34381367 PMCID: PMC8350133 DOI: 10.3389/fphar.2021.714584] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Accepted: 07/14/2021] [Indexed: 02/05/2023] Open
Abstract
Modified Huangqi Chifeng decoction (MHCD) has been used to reduce proteinuria in immunoglobulin A nephropathy (IgAN) for many years. Previously, we have demonstrated its protective role in glomerular mesangial cells. Podocyte injury, another key factor associated with proteinuria in IgAN, has also attracted increasing attention. However, whether MHCD can reduce proteinuria by protecting podocytes remains unclear. The present study aimed to investigate the protective effects of MHCD against podocyte injury in a rat model of IgAN. To establish the IgAN model, rats were administered bovine serum albumin, carbon tetrachloride, and lipopolysaccharide. MHCD in three doses or telmisartan was administered once daily for 8 weeks (n = 10 rats/group). Rats with IgAN developed proteinuria at week 6, which worsened over time until drug intervention. After drug intervention, MHCD reduced proteinuria and had no effect on liver and kidney function. Furthermore, MHCD alleviated renal pathological lesions, hyperplasia of mesangial cells, mesangial matrix expansion, and podocyte foot process fusion. Western blot analysis revealed that MHCD increased the expression of the podocyte-associated proteins nephrin and podocalyxin. Additionally, we stained podocyte nuclei with an antibody for Wilms’ tumor protein one and found that MHCD increased the podocyte number in rats with IgAN. In conclusion, these results demonstrate that MHCD attenuates proteinuria by reducing podocyte injury.

Abstract
Chronic atrophic gastritis (CAG) is well-known related with multiple pathogenic factors and normally therapies comprised by western or Chinese medicines. The present study was designed to identify the bacterial community characterized by 16S rRNA amplicon sequencing and determine the modulate affection of bacterial composition response western and Chinese medicine Qinghuayin (QHY) as well as antibiotic on model rats. The result shown the overall structure alteration of bacterial appeared under medicine intervened, antibiotic caused a marked depletion in bacterial diversity and richness. The enrichments of Firmicutes (85.1-90.7%) in antibiotic-free converts into Bacteroidetes (30.7-34.6%) in antibiotic-added model rat were demonstrated. Firmicutes as the most dominant phylum in antibiotic-free treatments and significantly decreased till 21.9-68.5% in antibiotic-added treatments. Especially QHY-treated rats showed highest RA of Firmicutes (90.7%) and the amelioration of CAG using QHY attributed by beneficial bacterial enrichment, especially Ruminococcus, Lactobacillus and Bifidobacterium. In addition, alpha and beta diversity analysis also demonstrated the clear dispersion and aggregation that revealed the alteration and steady of bacterial community structures. In summary, QHY has potential application value in the treatment of CAG, which attributed to close relation with the modulatory of internal bacterial communities.

Front Pharmacol 2020; 11:1080. [PMID: 32765277 PMCID: PMC7381112 DOI: 10.3389/fphar.2020.01080] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 07/02/2020] [Indexed: 12/21/2022] Open
Abstract
Immunoglobulin A nephropathy (IgAN) is one of the most frequent kinds of primary glomerulonephritis characterized by IgA immune complexes deposition and glomerular proliferation. Zhen-wu-tang (ZWT), a well-known traditional Chinese formula has been reported to ameliorate various kidney diseases. However, its pharmacological mechanism remains unclear. Exosomes have been described in diverse renal diseases by mediating cellular communication but rarely in the IgAN. The purpose of the present study is to explore whether the underlying mechanisms of the effect of ZWT on IgAN is correlated to exosomes. Our results demonstrated that in human renal tubular epithelial cells (HK-2) stimulated by lipopolysaccharide, exosomes are obviously released after ZWT-containing serum treatment especially with 10% ZWT. In addition, once released, HK-2-derived exosomes were uptaked by human mesangial cells (HMC), which impeded the activation of NF-κB/NLRP3 signaling pathway to exert anti-inflammatory effects in a lipopolysaccharide induced proliferation model. Moreover, IgAN rat model was established by bovine serum albumin, CCL4 mixed solution and LPS. We found that 10% ZWT could significantly promote the release of exosomes from HK-2 and inhibit HMC proliferation to improve inflammation. Thus HK-2-derived exosomes treated with 10% ZWT (ZWT-EXO) were administered to the rats by tail vein injection. Our results showed that ZWT-EXO decreased the levels of 24 h proteinuria, urinary erythrocyte, IgA deposition in glomerulus and renal pathological injury which ameliorated the kidney damage. In addition, ZWT was able to dramatically promote secretion of exosomes in renal tissues while blocked NF-κB nuclear translocation as well as activation of NLRP3 inflammasome, leading to the inhibition of IL-1β and caspase-1. In conclusion, our study reveal that ZWT has protective effects on IgAN by regulating exosomes secretion to inhibit the activation of NF-κB/NLRP3 pathway, thereby attenuating the renal dysfunction. These findings may provide a new therapeutic target for the treatment of IgAN.

Abstract
Introduction Guillain-Barré syndrome (GBS) is a worldwide demyelinating polyradiculopathy and polyneuropathy. Currently, there is no specific drug for GBS, and established treatment is generally based on immune-modulating treatment with plasma exchange or intravenous immunoglobulin in combination with supportive care. This study aimed to investigate the efficiency of integrated Chinese and Western medicine for acute GBS treatment. Methods We enrolled 73 subjects, and randomly divided them into two groups: 35 cases in the traditional Chinese medicine (TCM) group, and 28 in the Control group. The Control group was treated with the common Western medicine for one month; and the TCM group was administrated with one month of common treatment combined with TCM medication. Results Compared to the controls, TCM significantly enhanced the treatment efficiency in symptom expression, including the TCM syndrome score, the activity of daily living score, Hughes functional score and sensory dysfunction assessment. The total effective rate of the TCM group was 94.29%, significantly better than controls (78.59%). Moreover, TCM provide better improvement in motor nerve conduction functions (distal motor latency and motor conduction velocity) and sensory nerve conduction functions (sensory conduction velocity and sensory nerve action potential) in median nerve, ulnar nerve, and common fibular nerve. Conclusion When combined with TCM administration, the GBS treatment could acquire better outcomes.
