Advances of traditional Chinese medicine preclinical mechanisms and clinical studies on diabetic peripheral neuropathy.

CONTEXT: Diabetic peripheral neuropathy (DPN) results in an enormous burden and reduces the quality of life for patients. Considering there is no specific drug for the management of DPN, traditional Chinese medicine (TCM) has increasingly drawn attention of clinicians and researchers around the world due to its characteristics of multiple targets, active components, and exemplary safety. OBJECTIVE: To summarize the current status of TCM in the treatment of DPN and provide directions for novel drug development, the clinical effects and potential mechanisms of TCM used in treating DPN were comprehensively reviewed. METHODS: Existing evidence on TCM interventions for DPN was screened from databases such as PubMed, the Cochrane Neuromuscular Disease Group Specialized Register (CENTRAL), and the Chinese National Knowledge Infrastructure Database (CNKI). The focus was on summarizing and analyzing representative preclinical and clinical TCM studies published before 2023. RESULTS: This review identified the ameliorative effects of about 22 single herbal extracts, more than 30 herbal compound prescriptions, and four Chinese patent medicines on DPN in preclinical and clinical research. The latest advances in the mechanism highlight that TCM exerts its beneficial effects on DPN by inhibiting inflammation, oxidative stress and apoptosis, endoplasmic reticulum stress and improving mitochondrial function. CONCLUSIONS: TCM has shown the power latent capacity in treating DPN. It is proposed that more large-scale and multi-center randomized controlled clinical trials and fundamental experiments should be conducted to further verify these findings.

Network Pharmacology Combined with Animal Models to Investigate the Mechanism of ChangPu YuJin Tang in the Treatment of Tourette Syndrome.

BACKGROUND: ChangPu YuJin Tang (CPYJT) is a Chinese herbal formula that has been shown to be an effective therapeutic strategy for pediatric patients with Tourette Syndrome (TS). Using an integrated strategy of network pharmacology and animal model, the aim of this study was to investigate the mechanism of CPYJT in the treatment of TS. METHODS: Compound libraries of CPYJT were established using databases, such as the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). The TCMSP database and Swiss Target Prediction database were used to predict the targets. The above results were constructed into a CPYJT-Drug-Component-Target network. Moreover, TS targets were predicted using GeneCards and other databases. The targets corresponding to the potential ingredients in CPYJT and the targets corresponding to TS were taken as the intersections to construct the CPYJT-TS network. The target network was analysed by PPI using the string database. GO and KEGG enrichment analyses were performed on the target network. The whole process was performed using Cytoscape 3.7.2 to make visual network diagrams of the results. CPYJT was characterised by Ultra-Performance Liquid Chromatography-Tandem Mass Spectrometry (UHPLC-MS). Transmission Electron Microscopy (TEM) was used to observe the structural changes of CPYJT on the neuronal cells of the IDPN model rats. RT-PCR and Western Blot were used to analyse the changes in the mRNA and protein expression levels of BDNF, TrkB, PI3K, and AKT in the cortex, striatum, and thalamus brain regions after CPYJT administration in IDPN model rats. RESULTS: Network pharmacology and UHPLC-MS studies revealed that CPYJT acted on the TS through multiple neurotransmitters and the BDNF/TrkB and PI3K/AKT signalling pathways. CPYJT ameliorated neurocellular structural damage in the cortex, striatum, and thalamus of TS model rats. Additionally, CPYJT up-regulated the levels of BDNF, TrkB, PI3k, and AKT in the cortex, striatum, and thalamus of TS model rats. CONCLUSION: It was found that CPYJT protected neuronal cells from structural damage in multiple brain regions and affected the expression levels of BDNF, TrkB, PI3K, and Akt in the cortex, striatum, and thalamus during TS treatment.

The mechanism of Shenlong Jianji treatment of idiopathic pulmonary fibrosis inhibits fibroblast-to-myofibroblast transformation via the TGF-ß1/smads signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Shenlong Jianji (SLJJ) is a Chinese herbal compound composed of traditional medicines for supplementing Qi, nourishing Yin, promoting blood circulation, and removing obstruction in channels. It is widely used to treat idiopathic pulmonary fibrosis (IPF) in China. However, the underlying mechanism of SLJJ remains unclear. AIM OF THIS STUDY: To elucidate the efficacy and mechanisms of SLJJ in the treatment of IPF through in vivo and in vitro experiments. MATERIAL AND METHODS: 84 Wistar rats were randomly and equally divided into 7 groups: the control group (CTRL), the sham operation group (SHAM), the model group (IPF), the low dose of SLJJ group (L-SLJJ), the middle dose of SLJJ group (M-SLJJ), the high dose of SLJJ group (H-SLJJ), and the pirfenidone group (PFD). The rats in the CTRL, SHAM, and IPF groups were given normal saline each time for 28 days; the SLJJ groups were given Shenlong Jianji (9 g kg-1·d-1, 18 g kg-1·d-1, 36 g kg-1·d-1), and pirfenidone was administered as a sequential dose. After 28 days, the general condition of the rats was evaluated, and samples were collected. The lung coefficient was measured. The pathological changes of lung in each group were observed by H&E staining and Masson staining. α-SMA, collagen 1, and E-cadherin proteins were detected by immunohistochemistry. α-SMA, collagen 1, vimentin, E-cadherin, N-cadherin, TGF-ß1, smad2, and smad3 proteins were detected by WB in vivo.In vitro, A scratch test was used to assess the ratio of cell migration. α-SMA, vimentin, E-cadherin, and N-cadherin protein levels were evaluated by a cellular immunofluorescence assay. TGF-ß1/smads signaling pathway was detected by WB. HPLC-Q-TOF/MS analysis was used to identify the active compounds in the SLJJ. Molecular docking determined the free binding energy of the compound with the TGF-ß1 protein. RESULTS: SLJJ significantly improved the respiratory symptoms, heart rate, mental state, and food intake of IPF group rats and decreased the lung coefficient. In the IPF group, inflammatory cells were infiltrated, and the thickened alveoli wall and alveoli collapse were shown, while significantly alleviating pathological changes in the SLJJ and PFD groups. Masson staining showed that SLJJ and PFD decreased the collagen expression. Immunohistochemical results showed that the expressions of α-SMA, collagen 1, and N-cadherin decreased in the SLJJ and PFD groups, while E-cadherin increased significantly compared with the IPF group. SLJJ regulates TGF-ß1/smads signaling pathway proteins in vivo. SLJJ decreased the ratio of migration in HFL-1 cells; SLJJ reduced the fluorescence intensity of α-SMA, vimentin, and N-cadherin and increased the fluorescence intensity of E-cadherin in primary rat lung (PRL) fibroblast cells and HFL-1 cells. WB results showed that SLJJ significantly down-regulated α-SMA, Vimentin, N-cadherin, TGF-ß1, smad2, and p-smad2/3 proteins expression and up-regulated E-cadherin protein expression in vitro, whereas SRI-011381 (a TGF-ß1 agonist) antagonized the effects of SLJJ. CONCLUSION: SLJJ inhibits idiopathic pulmonary fibrosis. The TGF- ß1/Smads signaling pathway can be the target of SLJJ, which inhibits fibroblast-to-myofibroblast transformation and is expected to be a new drug for the treatment of IPF.

[Role of TGF-ß/Smad signaling pathway in diabetic kidney disease and research progress of traditional Chinese medicine intervention].

Diabetic kidney disease is an important microvascular complication of diabetes and the leading cause of end-stage renal disease. Its pathological characteristics mainly include epithelial mesenchymal transition(EMT) in glomerulus, podocyte apoptosis and autophagy, and damage of glomerular filtration barrier. Transforming growth factor-ß(TGF-ß)/Smad signaling pathway is specifically regulated by a variety of mechanisms, and is a classic pathway involved in physiological activities such as apoptosis, proliferation and differentiation. At present, many studies have found that TGF-ß/Smad signaling pathway plays a key role in the pathogenesis of diabetic kidney disease. Traditional Chinese medicine has significant advantages in the treatment of diabetic kidney disease for its multi-component, multi-target and multi-pathway characteristics, and some traditional Chinese medicine extracts, traditional Chinese medicines and traditional Chinese medicine compound prescription improve the renal injury of diabetic kidney disease by regulating TGF-ß/Smad signaling pathway. This study clarified the mechanism of TGF-ß/Smad signaling pathway in diabetic kidney disease by expounding the relationship between the key targets of the pathway and diabetic kidney disease, and summarized the research progress of traditional Chinese medicine in the treatment of diabetic kidney disease by interfering with TGF-ß/Smad signaling pathway in recent years, to provide reference for drug research and clinical treatment of diabetic kidney disease in the future.

ObjectiveTo mine the compatibility rules of patented traditional Chinese medicine (TCM) compound prescriptions for treating chronic atrophic gastritis (CAG) by systems pharmacology and molecular docking methods, and predict the targets and molecular mechanisms of Chinese medicinals with different efficacy in the treatment of CAG. MethodThe TCM compound prescriptions for treating CAG were extracted from the patent system of the China National Intellectual Property Administration. The active components and targets of the prescriptions were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Traditional Chinese Medicine Integrative Database (TCMID), and UniProt. The candidate targets and pathways of CAG were obtained from GeneCards, DisGeNet, Online Mendelian Inheritance in Man (OMIM), MalaCards, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Reactome. The gene ontology (GO) functional annotation and KEGG pathway enrichment were realized by R Studio 4.1.2. STRING11.0 was employed to build the protein-protein interaction (PPI) network, and AutoDock Vina 4.2.6 was used for the docking between key targets and components. ResultA total of 228 TCM compound prescriptions for treating CAG were extracted. The medicinals used in these prescriptions mainly had warm or cold nature, bitter or sweet taste, tropism to the spleen, stomach, and liver meridians, and the efficacy of tonifying Qi, regulating Qi movement, clearing heat, and activating and toniying blood. The prescriptions mainly treated CAG via p53, mitogen-activated protein kinase (MAPK), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), forkhead box protein O (FoxO), vascular endothelial growth factor (VEGF), and hypoxia-inducible factor-1 (HIF-1) signaling pathways. Molecular docking results confirmed that the active components in the prescriptions had docking activities with key receptor proteins. ConclusionThis study preliminarily analyzed the compatibility rules of TCM compound prescriptions in the treatment of CAG. The medicinals with different efficacy treat CAG by regulating cell proliferation, apoptosis, and oxidative stress response, preventing carcinogen production, promoting gastric acid secretion, and improving local microcirculation in a multi-target, multi-pathway, multi-link manner. The findings facilitate the research on the TCM treatment of CAG.

Effect and Mechanism of Baoshen Prescription in Alleviating Renal Fibrosis in UUO Mice by Regulating ERK/p38 MAPK Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo observe the protective effect of Baoshen prescription against renal fibrosis and explore its underlying mechanism through network pharmacology， molecular docking， and in vivo experiments. MethodAll mice were randomly divided into sham surgery group， model group， low-， medium-， and high-dose Baoshen prescription groups， and a benazepril hydrochloride group. Unilateral ureteral obstruction （UUO） was performed to establish a renal fibrosis model， and the administration of Baoshen prescription at low， medium， and high doses （0.455， 0.91， and 1.82 g·kg-1）， and benazepril hydrochloride （1.68 mg·kg-1） or distilled water began on the same day as model preparation. Mice in the model group and the sham surgery group were given an equal volume of distilled water. The intervention was carried out once daily for 14 days. Mouse serum levels of blood urea nitrogen （BUN） and creatinine （Cr） were measured. Hematoxylin-eosin （HE） staining and Masson staining were used to observe renal pathological changes. Western blot and immunohistochemistry were used to assess the expression of fibronectin （FN）， α-smooth muscle actin （α-SMA）， and E-cadherin， which are related to renal fibrosis. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to measure the mRNA expression of transforming growth factor-β1 （TGF-β1）， tumor necrosis factor-α （TNF-α）， NOD-like receptor protein 3 （NLRP3）， and monocyte chemoattractant protein-1 （MCP-1） in renal tissues. The mechanism of Baoshen prescription in improving renal fibrosis was explored through network pharmacology， molecular docking， and Western blot experiments. ResultCompared with the sham surgery group， the model group showed significantly increased levels of BUN and Cr （P<0.01）. The model group exhibited abnormal renal glomerular morphology， loss of tubular brush borders， tubular dilation， and an enlarged area of blue collagen fibers. Mice in the model group showed significantly elevated levels of FN and α-SMA （P<0.01）， significantly decreased expression of E-cadherin （P<0.01）， and significantly increased expression of TGF-β1， TNF-α， NLRP3， and MCP-1 mRNA （P<0.05， P<0.01）. Compared with the model group， the Baoshen prescription groups showed significantly reduced BUN and Cr levels （P<0.01）， alleviated renal pathological damage， improved fibrosis， reduced expression of FN and α-SMA （P<0.01）， increased E-cadherin expression （P<0.01）， and downregulated mRNA expression of TGF-β1， TNF-α， NLRP3， and MCP-1 （P<0.05， P<0.01）. Network pharmacology and molecular docking predicted that Baoshen prescription could potentially improve renal fibrosis through the extracellular signal-regulated kinase （ERK）/p38 mitogen-activated protein kinase （MAPK） signaling pathway. Pharmacological research showed that compared with the sham surgery group， the model group exhibited significantly increased expression of phosphorylated （p）-ERK and p-p38 （P<0.05， P<0.01）. Compared with the model group， medium- and high-dose Baoshen prescription groups showed significantly downregulated expression of p-ERK and p-p38 proteins （P<0.05， P<0.01）. ConclusionBaoshen prescription can effectively improve renal fibrosis induced by UUO in mice， and its mechanism of action may be related to the ERK/p38 MAPK signaling pathway.

Recent Advances in Traditional Chinese Medicine for Treatment of Podocyte Injury.

Podocyte is also called glomerular epithelial cell, which has been considered as the final gatekeeper of glomerular filtration barrier (GFB). As a major contributor to proteinuria, podocyte injury underlies a variety of glomerular diseases and becomes the challenge to patients and their families in general. At present, the therapeutic methods of podocyte injury mainly include angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, steroid and immunosuppressive medications. Nevertheless, the higher cost and side effects seriously disturb patients with podocyte injury. Promisingly, traditional Chinese medicine (TCM) has received an increasing amount of attention from different countries in the treatment of podocyte injury by invigorating spleen and kidney, clearing heat and eliminating dampness, as well enriching qi and activating blood. Therefore, we searched articles published in peer-reviewed English-language journals through Google Scholar, PubMed, Web of Science, and Science Direct. The protective effects of active ingredients, herbs, compound prescriptions, acupuncture and moxibustion for treatment of podocyte injury were further summarized and analyzed. Meanwhile, we discussed feasible directions for future development, and analyzed existing deficiencies and shortcomings of TCM in the treatment of podocyte injury. In conclusion, this paper shows that TCM treatments can serve as promising auxiliary therapeutic methods for the treatment of podocyte injury.

[Advances in research of traditional Chinese medicine for promoting bile secretion and excretion].

Cholagogic traditional Chinese medicines refer to those that can promote bile secretion and excretion, strengthen gallbladder contraction and promote gallbladder emptying. They are mainly used to treat cholecystitis, gallstones, cholestasis, biliary tract infection, jaundice hepatitis and other diseases in clinical application. As a traditional medicine in our country, Chinese herbal medicines have many advantages, such as extensive resources, low cost, little or no toxic and side effects, and in addition, it is not easy for animals to produce drug resistance. With the progress of science and technology and the rapid development of traditional Chinese medicine, many achievements have been made in the research of cholagogic traditional Chinese medicines. Traditional Chinese medicine plays a cholagogic role mainly by promoting bile secretion, regulating SCP2 mRNA, FXR, BSEP and efflux transporter protein, dissolving cholesterol, promoting the relaxation of Oddi's sphincter and changing the composition of bile, etc. Traditional Chinese medicine decoction, traditional Chinese medicine preparation, Chinese medicine combined with acupuncture, ear acupoint pressing, soaking bath, western medicine and alike are often used to treat biliary system diseases in clinical practice. The effective rate of combination of traditional Chinese medicine and other methods was significantly higher than that of compound prescription, western medicine, acupuncture and soaking bath alone. General attack therapy and new therapies are also used in clinical treatment. The clinical effect of traditional Chinese medicine is remarkable. By means of literature review, the pharmacological effects, mechanism and clinical application of Chinese herbal medicines and compound prescriptions with gallbladder-promoting effect in the past 15 years were summarized in this paper. At the same time, some existing problems were found and prospects were expected.

The effect and mechanism of YH0618 granule on chemotherapy- induced hair loss in patients with breast cancer: study protocol for a randomized, double-blind, multi-center clinical trial.

BACKGROUND: Hair loss is one of the most common side effects of chemotherapy, and can cause persistent negative emotions, further affecting therapeutic effects and reducing the quality of life. However, there are no clinically safe and effective methods to solve the problem at present. Our previous clinical and animal studies showed that a medicinal and edible decoction, YH0618, could significantly promote hair growth in cancer patients after chemotherapy, without interfering with the anti-tumor effects of chemotherapy. Besides, the theory of Chinese Medicine believes that the "Essence of the kidney is reflected on the hair". Therefore, this study will further explore the efficacy of YH0618 granule on chemotherapy-induced hair loss in patients with breast cancer by a randomized, double-blind, multi-center clinical trial and elucidate the potential mechanism from the aspect of kidney deficiency or renal dysfunction. METHODS/DESIGN: Eligible breast cancer patients who will start chemotherapy will be randomly divided into group A (YH0618 granule) and group B (placebo). The chemotherapeutic agents contain taxanes or/and anthracyclines, and the chemotherapy regimen will be for at least six cycles with a cycle every 3 weeks. Subjects assigned to group A will receive YH0618 granules twice a day (6 g each time), 6 days a week, mixed with 300 ml warm water from the first to the fourth chemotherapy cycle. Subjects in group B will receive the placebo granule in the same manner. The primary outcome is the time point of occurrence of hair loss reaching grade II as assessed by the WHO Toxicity Grading Scale, and objective indices of hair quality and hair-follicle growth recorded by a hair and scalp detector before the fifth chemotherapy cycle. Secondary outcomes include changes of facial color and thumbnail color, grading of thumbnails ridging, assessment of quality life, level of fatigue, routine blood test results, hepatic and renal function, and certain medical indicators which can reflect kidney deficiency in Chinese Medicine. DISCUSSION: This research is of great significance for the treatment of cancer and improving the quality of life of cancer patients. The study may provide the most direct evidence for meeting clinical needs and lay a solid scientific foundation for later product development.
