Traditional Chinese Medicine in Treatment of Parkinson's Disease by Regulating TLR4/NF-κB Signaling Pathway： A Review / 中国实验方剂学杂志

Parkinson's disease （PD） is a common neurological degenerative disease in the middle-aged and elderly， characterized by pathological changes of progressive degeneration of dopaminergic neurons in the substantia nigra and Lewy body formation， with high prevalence and long course of disease. The drug is mainly used to treat PD in western medicine， and the early curative effect is remarkable. However， with the progression of the disease and the long-term use of the drug， the efficacy will be significantly reduced， or there may be sports complications， and the long-term efficacy is not good. As a traditional medical system， traditional Chinese medicine has a unique understanding of PD. Traditional Chinese medicine plays an important role in the treatment of PD， which is natural， mild， safe， and effective， and it can cooperate with western medicine to enhance its efficacy and reduce the adverse reactions of western medicine. The pathogenesis of PD is complex， involving multiple levels such as mitochondrial dysfunction and apoptosis. Neuroinflammation is also involved in the progressive degeneration of dopaminergic neurons in PD. The Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB） signaling pathway is a classic inflammatory pathway， and its expression changes play an important role in the occurrence and development of inflammatory response in the body. In recent years， the research on this pathway in TCM is increasing. This paper summarized the literature of traditional Chinese and western medicine in the past 10 years and reviewed the relevant mechanism of TCM regulation of TLR4/NF-κB pathway in the treatment of PD from the aspects of TCM monomer， compound， and other TCM therapies， so as to provide some references for the search for new targets of drug therapy and gene therapy and the in-depth study of TCM prevention and treatment of PD.

Mechanism of Sanhuang Xiexintang in Protecting Stress Gastric Ulcer in Rats / 中国实验方剂学杂志

ObjectiveTo explore the molecular mechanism of Sanhuang Xiexintang （SHXXT） in protecting stress gastric ulcer （SGU） in rats through network pharmacology， molecular docking， and animal experiments. MethodThe active ingredients and corresponding targets in SHXXT were collected and screened from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， Traditional Chinese Medicine Information Database （TCMID）， Bioinformation Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine （BATMAN-TCM）， and Swiss Target Prediction database. SGU-related targets were screened from the Online Mendelian Inheritance in Man （OMIM）， Therapeutic Target Database （TTD）， GeneCards database， and PharmGKB database. Herbal-ingredient-target （H-C-T） network was constructed by using Cytoscape 3.9.1 software. Protein-protein interaction （PPI） of drug and disease intersection targets was analyzed by using the Protein Interaction Platform （STRING） database. Gene ontology （GO） enrichment analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analysis were conducted through the Database for Annotation Visualization and Integrated Discovery （DAVID）. The active ingredients and key targets were validated using AutodockVina 1.2.2 molecular docking software， and the experimental results were further validated through animal experiments. ResultThe 55 active ingredients were screened， and 255 potential target genes for SHXXT treatment of SGU were predicted. The PPI analysis showed that protein kinase B （Akt）， phosphatase and tensin homolog deleted on chromosome ten （PTEN）， tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and cyclooxygenase-2 （COX-2） are the core targets of SHXXT for protecting SGU. GO and KEGG analyses showed that SHXXT may affect the development of SGU by regulating various biological processes such as the phosphoinositide 3-kinase （PI3K）/Akt signaling pathway and inflammatory processes. The molecular docking results showed that both the active ingredients and key targets had good binding ability. Animal experiments showed that compared with the blank group， the ulcer index （UI） of the model group was significantly increased （P<0.01）， and the serum levels of TNF-α and IL-1β significantly increased （P<0.01）. The phosphorylation level of PTEN in gastric mucosal tissue was significantly down-regulated （P<0.05）. The phosphorylation levels of PI3K， Akt， and nuclear factor kappa-B （NF-κB） were significantly up-regulated （P<0.05）. Compared with the model group， the UI of the treatment group was significantly reduced （P<0.01）， and the serum levels of TNF-α and IL-1β were significantly reduced （P<0.01）. The phosphorylation level of PTEN in gastric mucosal tissue was significantly up-regulated （P<0.01）， and the phosphorylation levels of PI3K， Akt， and NF-κB were significantly downregulated （P<0.01）. ConclusionThe application of network pharmacology prediction， molecular docking simulation， and animal experimental validation confirms that SHXXT regulates the PI3K/Akt/NF-κB signaling pathway to regulate the inflammatory response of rats and thus protects the gastric mucosa of SGU rats.

ObjectiveTo study the effects of Epimedii Folium polysaccharides on mice with exercise-induced fatigue and explore its possible mechanism of action. MethodICR male mice screened by swimming training were randomly divided into a control group， model group， vitamin C group， and low， medium， and high dose groups of Epimedii Folium polysaccharides， with eight mice in each group. The exercise-induced fatigue model was established by weight-bearing swimming training in each group except for the control group. After two weeks of weight-bearing swimming， the Epimedii Folium polysaccharide groups were given 100， 200， 400 mg∙kg-1 of Epimedii Folium polysaccharides by gavage， and the vitamin C group was given 200 mg∙kg-1 of vitamin C by gavage. The control group and the model group were given equal amounts of saline for 14 d. At the end of the experimental period， the body mass of the mice in each group and the time of last swimming due to exhaustion were recorded. Serum urea nitrogen （BUN）， lactic acid （LA）， lactate dehydrogenase （LDH）， malondialdehyde （MDA）， superoxide dismutase （SOD）， glutathione peroxidation （GSH-Px）， myoglycogen （MG） in skeletal muscle， hepatic glycogen （HG） in the liver were detected by kits. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in muscle tissue. Western blot was used to detect the protein expression of p38 mitogen-activated protein kinase （p38 MAPK）， phosphorylation （p）-p38 MAPK， extracellular signal-regulated kinase1/2 （ERK1/2）， nuclear factor-κB （NF-κB）， p-NF-κB， interleukin-1β （IL-1β）， and interleukin-6 （IL-6） in muscle tissue. The immunofluorescence （IF） method was used to detect the expression of tumor necrosis factor-α （TNF-α） in skeletal muscle tissue of mice in each group. ResultCompared with the control group， the body mass of mice in the model group decreased， and the time of last swimming due to exhaustion decreased （P<0.01）. In addition， there were significantly higher serum levels of the fatigue metabolites LA， LDH， BUN， and lipid peroxidation product MDA （P<0.01） and decreased levels of MG， HG， SOD， and GSH-Px （P<0.01）. The protein expressions of p-p38 MAPK， ERK1/2， p-NF-κB， IL-1β， IL-6， and TNF-α in skeletal muscle tissue were significantly higher than those of the control group （P<0.01）. Compared with the model group， the body mass and time of last swimming due to exhaustion of the mice in the low， medium， and high dose groups of Epimedii Folium polysaccharides and the vitamin C group were increased （P<0.05， P<0.01）， and the contents of LA， LDH， BUN， and MDA were significantly decreased （P<0.05， P<0.01）. The levels of MG， HG， SOD， and GSH-Px increased （P<0.05， P<0.01）， and the protein expression levels of p-p38 MAPK， ERK， p-NF-κB， IL-1β， IL-6， and TNF-α in skeletal muscle tissue decreased （P<0.05， P<0.01）. ConclusionEpimedii Folium polysaccharides can play a role in alleviating exercise-induced fatigue by inhibiting the p38 MARK/NF-κB signaling pathway， thereby reducing the accumulation of metabolites， improving the activity of antioxidant enzymes， increasing the glycogen content of the body， and reducing inflammation in skeletal muscle.

OBJECTIVE To explore the neuroprotective effect of sodium aescinate on rats with Parkinson’s disease by regulating the silent information regulator 1 （SIRT1）/nuclear factor-κB （NF-κB） signaling pathway. METHODS The Parkinson’s disease rat model was constructed by using 6-hydroxydopamine injection method. Forty-eight rats successfully modeled were randomly divided into model group， sodium aescinate low-dose group （1.8 mg/kg）， sodium aescinate high-dose group （3.6 mg/kg）， sodium aescinate+EX527 （sodium aescinate 3.6 mg/kg+SIRT1 inhibitor EX527 5 mg/kg） group， with 12 rats in each group. Another 12 healthy rats were selected as the sham operation group. Each group was injected with the corresponding drug solution intraperitoneally， once a day， for 21 consecutive days. Twenty-four hours after the end of the last administration， the motor and cognitive functions of rats were detected， and the morphology of neurons in the substantia nigra and CA1 region of hippocampal tissue were observed. The content of dopamine （DA） in the nigrostriatal and the expression levels of tyrosine hydroxylase （TH） and α-synuclein （α-Syn） in the substantia nigra were detected. The serum levels of pro-inflammatory factor [interleukin-6 （IL-6）， IL-18]， anti-inflammatory factor （IL-10）， and the expression levels of SIRT1， phosphorylated NF-κB p65 （p-NF-κB p65） and NF- κB p65 protein in nigrostriatal were detected. RESULTS Compared with sham operation group， the neurons in the substantia nigra and CA1 region of hippocampal tissue were seriously damaged in model group； the number of rotations， escape latency， the expression levels of α-Syn in substantia nigra， the levels of serum pro-inflammatory factors， the relative expression ratio of p-NF- κB p65 and NF-κB p65 protein in nigrostriatal were increased or prolonged significantly （P＜0.05）； the target quadrant residence time， the content of DA in nigrostriatal， the expression level of TH in substantia nigra， the serum level of anti-inflammatory factor， and the expression level of SIRT1 protein in substantia nigra striatum were significantly decreased or shortened （P＜0.05）. Compared with model group， the damage degrees of neuron in sodium aescinate groups were alleviated， and the quantitative indicators were significantly improved， which were more significant in the high-dose group （P＜0.05）； EX527 could reverse the improvement effect of high-dose sodium aescinate （P＜0.05）. CONCLUSIONS Sodium aescinate can inhibit the activation of NF-κB signal by up-regulating the protein expression of SIRT1， thereby reducing the neuroinflammation of rats with Parkinson’s disease， improving the motor and cognitive dysfunctions， and finally playing a neuroprotective role.

Natural Products Treat Atopic Dermatitis via NF-κB Signaling Pathway： A Review / 中国实验方剂学杂志

Atopic dermatitis （AD） is a chronic， recurrent， inflammatory， and pruritus skin disease caused by multiple internal and external factors， ranking first in the global burden of skin diseases. Due to the adverse reactions and high costs of conventional treatments and biologics， the development of natural products has attracted much attention. The nuclear factor-κB （NF-κB） signaling pathway is a key pathway for inhibiting inflammation and modulating immunity. This paper summarizes the pharmacological effects and molecular mechanisms of natural products such as flavonoids， alkaloids， phenols， terpenoids， coumarins， glycosides， and anthraquinones via NF-κB signaling pathway， aiming to provide guidance for the development of natural products. Basic studies have shown that natural products have high safety and efficacy. Oral or topical administration of natural products can regulate the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， mitogen-activated protein kinase （MAPK）， nuclear factor erythroid 2-related factor 2 （Nrf2）， high mobility group box 1 protein （HMGB1）/receptor for advanced glycation endproducts （RAGE）， and nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3） signaling pathways to exert anti-inflammatory， anti-allergy， antioxidant activities， thus reversing the pathological changes of AD. However， it is worth noting that the clinical application of natural products is still insufficient， and more rigorous clinical trials are still needed to verify their effects. The basic experiments and clinical evidence prove that natural products may play a role in alleviating AD， which provide a basis for evaluating the functioning mechanism of natural active substances and enrich the candidates for the development of potential drugs.

Chaihu Longgu Mulitang Relieves Generalized Anxiety Disorder in Rats via p38 MAPK/NF-κB Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo study whether Chaihu Longgu Mulitang can inhibit hypothalamic inflammation， mitigate anxiety-like behavior， and alleviate anxiety symptoms by regulating the p38 mitogen-activated protein kinase/nuclear factor-κB （p38 MAPK/NF-κB） signaling pathway in the rat model of generalized anxiety disorder （GAD）. MethodTwelve out of 74 Wistar rats were randomly selected as the blank group， and the remaining rats were subjected to chronic restraint stress for the modeling of GAD. The open field test （OFT） and elevated Porteus maze test （PMT） were conducted 14 days after modeling to detect the anxiety-like behaviors. Sixty successfully modeled rats were selected and randomized into model， low-， medium-， and high-dose （6， 12， and 24 g·kg-1， respectively） Chaihu Longgu Mulitang， and diazepam （1 mg·kg-1） groups （n=12） and administrated with corresponding drugs for 14 consecutive days. OFT and PMT were then carried out to examine the anxiety-like behaviors of the rats. The levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-1β （IL-1β） in the hypothalamus and serum of rats were determined by the enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）was conducted to determine the mRNA levels of p38 MAPK， NF-κB p65， nuclear factor κB inhibitor α （IκBα）， and ionized calcium binding adaptor molecule 1 （Iba-1）. The protein levels of p38 MAPK， phosphorylated （p）-p38 MAPK， NF-κB p65， p-NF-κB p65， and IκBα in the hypothalamus of rats were determined by Western blot. The expression of Iba-1 in the hypothalamic microglia was detected by immunofluorescence assay. ResultCompared with the blank group， the model group had decreased body weight， scattered dark yellow fur， increased irritability， and preference to hibernation in the corner. In addition， the modeled rats showed increased edge movement distance and time in OFT （P<0.01） and decreased movement distance and time and the number of entries in the open arm in PMT （P<0.01）. The modeling increased the fluorescence intensity of Iba-1 in paraventricular nucleus of hypothalamus （P<0.01）， elevated the levels of IL-1β， IL-6， and TNF-α in the serum and hypothalamus （P<0.01）， up-regulated the protein and mRNA levels of p38 MAPK， NF-κB p65， p-p38 MAPK， p-NF-κB p65， and Iba-1 （P<0.05， P<0.01）， and down-regulated the protein and mRNA levels of IκBα （P<0.01） in the hypothalamus. Compared with the model group， medium- and high-dose Chaihu Longgu Mulitang and diazepam increased the body weight， improved the fur and behaviors， decreased the edge movement distance and time in OFT （P<0.05， P<0.01）， and increased the movement distance and time in the open arm in PMT （P<0.05， P<0.01）. Furthermore， they decreased the fluorescence intensity of Iba-1 in hypothalamic microglia （P<0.05， P<0.01）， lowered the levels of IL-1β， IL-6， and TNF-α in the serum and hypothalamic tissue （P<0.05， P<0.01）， down-regulated the mRNA and protein levels of p38 MAPK， NF-κB p65， p-p38 MAPK， p-NF-κB p65， and Iba-1 （P<0.05， P<0.01）， and up-regulated the mRNA and protein levels of IκBα （P<0.05， P<0.01） in the hypothalamus. ConclusionChaihu Longgu Mulitang can mitigate anxiety-like behaviors and relieve anxiety in GAD rats by inhibiting the p38 MAPK/NF-κB signaling pathway and reducing the activation of microglia and the levels of pro-inflammatory cytokines in the hypothalamus.

Role of NF-κB Signaling Pathway in "Reflux Esophagitis-esophageal Cancer" and Traditional Chinese Medicine Intervention：A Review / 中国实验方剂学杂志

Reflux esophagitis is an inflammatory disease of esophageal mucosa damage caused by the reflux of gastric contents into the esophagus. Its incidence is on the rise， and it has become an important precancerous disease of esophageal cancer. Studies have shown that the continuous inflammatory response stimulates the esophageal mucosa， causing abnormal proliferation of esophageal epithelial cells and damage to esophageal mucosal tissue， which eventually leads to the occurrence of heterogeneous hyperplasia and even carcinogenesis. The nuclear transcription factor-kappa B （NF-κB） signaling pathway is one of the most classical inflammatory and cancer signaling pathways. It has been found that abnormal activation of the NF-κB signaling pathway is crucial to the development and prognosis of reflux esophagitis and esophageal cancer. It is widely involved in the proliferation， autophagy， apoptosis， and inflammatory response of esophageal epithelial cells and tumor cells， accelerating the transformation of reflux esophagitis to esophageal cancer and making it a potential target for the treatment of reflux esophagitis and esophageal cancer. Currently， there is no specific treatment for reflux esophagitis and esophageal cancer， and large side effects often appear. Therefore， finding a promising and safe drug remains a top priority. In recent years， traditional Chinese medicine scholars have conducted a lot of research on NF-κB signaling pathway， and the results indicate that NF-κB signaling pathway is an important potential target for traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer， but there is a lack of comprehensive and systematic elaboration. Therefore， this paper summarized the relevant studies in recent years， analyzed the relationship among NF-κB signaling pathway， reflux esophagitis， esophageal cancer， and transformation from inflammation to cancer， and reviewed the research literature on the regulation of the NF-κB signaling pathway in traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer， so as to provide new ideas for the prevention and treatment of reflux esophagitis and esophageal cancer.

This study mainly explores the role of myeloid differentiation primary response protein 88 (MyD88) in tumorigenesis and development, to identify active compounds targeting MyD88. CRISPR/Cas9 system and xenograft tumor model were used to detect the effect of MyD88 deletion on tumor growth, and the experimental animal ethics review number was PZSHUTCM200828006. Microscale thermophoresis technology (MST) was used to identify compounds directly bind to MyD88 and further detect the impact of candidate small molecules on cell proliferation. Results showed that depletion of MyD88 significantly inhibited xenograft tumor growth of colon cancer, pancreatic cancer and skin cancer and the activity of NF-κB signaling pathway. MST showed that nordihydroguaiaretic acid (NDGA) bound to MyD88, with the binding dissociation constant Kd of 14.61 µmol·L-1. NDGA inhibited NF-κB reporting system activation and phosphorylation of p65, the key factor in NF-κB signal pathway. In addition, the results of colony formation assay showed that NDGA suppressed the proliferation of tumor cells. The above results show that, MyD88 is a potential therapeutic target for colon cancer, pancreatic cancer and skin cancer, NDGA directly binds to MyD88 and inhibits the activity of NF-κB signaling pathway, as well as inhibits the proliferation of pancreatic cancer, skin cancer and colon cancer cells.

The treatment groups received oral administration for 7 days prior to modeling. After 12 hours of modeling， mouse lung tissues were taken to measure the wet/dry weight ratio （W/D）. Hematoxylin-eosin （HE） staining was performed to observe the pathological morphological changes in lung tissues. Bronchoalveolar lavage fluid （BALF） was collected for total cell count using a cell counter， and Wright-Giemsa staining was conducted to classify and quantify inflammatory cells （neutrophils and macrophages）. Enzyme-linked immunosorbent assay （ELISA） was used to determine the expression levels of inflammatory cytokines tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in BALF. Western blot analysis was performed to detect the expression of nuclear factor-κB （NF-κB） inhibitory protein α （IκBα）， NF-κB p65， and their phosphorylated proteins， and the ratio of phosphorylated protein/total protein was calculated. ResultCompared with the normal group， the model group exhibited severe lung tissue damage， disrupted alveolar structure， thickened alveolar walls， infiltration of extensive inflammatory cells and red blood cells， and significantly aggravated lung edema （P<0.01）. The total cell count， inflammatory cell count， expression levels of IL-6， and TNF-α in BALF， as well as NF-κB p65 and phosphorylated IκBα in lung tissues， were significantly upregulated in the model group （P<0.01）. Compared with the model group， high-， medium-， and low-dose Linggui Zhugantang groups， as well as the dexamethasone group， showed improved lung injury， reduced lung edema （P<0.01）， downregulated total cell count， neutrophil count， expression levels of IL-6 and TNF-α in BALF， and NF-κB p65 and phosphorylated IκBα in lung tissues （P<0.01）， and reduced macrophage count （P<0.05）. ConclusionLinggui Zhugantang has anti-inflammatory and protective effects on LPS-induced ALI in mice， effectively reducing inflammation and promoting diuresis and edema elimination. Its mechanism may be related to the inhibition of NF-κB pathway activation.

ObjectiveTo explore the effect of Tongxie Yaofang on the immune microenvironment of colorectal cancer in mice under chronic stress and the underlying mechanism. MethodA total of 40 male SPF BABL/C mice were randomized into normal group， stress group， Tongxie Yaofang group （13.65 g·kg-1）， and Tongxie Yaofang-stress group （13.65 g·kg-1）， with 10 in each group. Chronic restraint stress was induced in mice and administration （ig） of Tongxie Yaofang began after 7 days of stress. On the 14th day， forced swim and tail suspension tests were used to examine the behavioral changes of mice after stress and the subcutaneous colorectal tumor was implanted in each group of mice. The effect of this prescription on the body mass and tumor volume of mice was observed. After the last administration， mouse serum and tumor samples were collected. The content of T lymphocytes （CD3+， CD4+， CD8+， and CD4+/CD8+） in tumor was detected by immunohistochemistry and flow cytometry and levels of corticosterone （CORT） in peripheral blood， and interleukin （IL）-2， interferon-γ （IFN-γ）， IL-6， and IL-10 in the serum were determined by enzyme-linked immunosorbent assay （ELISA）. The protein expression of inhibitor of nuclear factor-κB（IκB） kinase α/β （IKKα/β）， nuclear factor-κB （NF-κB）α （IκBα）， NF-κB p65， and phosphorylated （p）-NF-κB p65 was measured by Western blot. ResultCompared with the normal group， the stress group had large tumor volume （P<0.05）， low content of CD3+， CD4+， and CD4+/CD8+ （P<0.05， P<0.01）， high content of CD8+， low content of T helper 1 （Th1）-secreted IFN-γ （P<0.05）， high content of T helper 2 （Th2）-secreted IL-10 （P<0.05） and CORT （P<0.05）， high protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05）， and low protein expression of IκBα （P<0.05）. Compared with the normal group， the Tongxie Yaofang group showed slow tumor growth， high content of CD3+， CD4+， and CD4+/CD8+ （P<0.01）， low content of CD8+ （P<0.05）， high content of Th1-secreted IL-2 and IFN-γ （P<0.05）， low content of Th2-secreted IL-6 and IL-10 （P<0.05）， low content of CORT， low protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05）， and high protein expression of IκBα （P<0.01）. Tongxie Yaofang-stress group demonstrated slower tumor growth， higher content of CD3+， CD4+， and CD4+/CD8+ （P<0.01）， smaller content of CD8+ （P<0.05）， higher content of IL-2 and IFN-γ （P<0.05）， lower content of IL-6， IL-10 （P<0.05）， and CORT （P<0.05）， lower protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05，P<0.01）， and higher protein expression of IκBα （P<0.01） than the stress group. ConclusionTongxie Yaofang can delay the growth of colorectal cancer under chronic stress and alleviate the deterioration of the immune microenvironment， possibly by inhibiting NF-κB signaling pathway， regulating the function of T lymphocyte subsets， and thus suppressing the secretion of pro-inflammatory factors.

Traditional Chinese Medicine Intervention in Colorectal Cancer Based on NF-κB Signaling Pathway： A Review / 中国实验方剂学杂志

Colorectal cancer （CRC） is one of the leading causes of cancer-related deaths worldwide， with increasing incidence and mortality rates. The disease often develops covertly and lacks specific symptoms in its early stages， leading to late-stage diagnoses in most patients. It has become a prominent research topic in the field of digestive system tumors. The exact mechanisms underlying CRC are not yet clear and involve factors such as genetics， gene mutations， inflammatory responses， and aberrant activation of tumor-related signaling pathways. Nuclear factor-kappa B （NF-κB） is a crucial transcription factor that participates in various biological processes， including inflammatory responses， immune responses， cell proliferation， and apoptosis. Research suggests that NF-κB， serving as a molecular link between inflammation and cancer， is highly expressed in CRC. It promotes the occurrence and development of CRC by regulating the activity of target genes such as cell pro-inflammatory factors， chemokines， angiogenic factors， metastasis factors， and anti-apoptotic proteins. Currently， common treatments for CRC include surgery， radiation therapy， and chemotherapy drugs like 5-fluorouracil. However， these treatments have limitations such as significant adverse reactions， high metastasis rates， and the development of drug resistance. Therefore， the search for effective， low-adverse-reaction drugs to replace or supplement current treatments is essential. In recent years， traditional Chinese medicine （TCM） has shown some effectiveness in preventing and treating CRC. TCM has been found to inhibit the growth of CRC cells by modulating the NF-κB signaling pathway， playing a positive role in the occurrence and progression of CRC. Based on the asthenia in origin and sthenia in superficiality and deficiency-excess in complexity in CRC， this article summarized and analyzed the mechanisms and effects of TCM interventions targeting the NF-κB signaling pathway in CRC， and reviewed advances of 10 Chinese medicinal compound formulas and 37 Chinese medicinal monomer components of different types， including flavonoids， phenols， alkaloids， glycosides， and terpenoids with the effects of dispelling pathogenic factors， reinforcing healthy qi， and removing toxins in the prevention and treatment of CRC by targeting the NF-κB pathway. It is found that Chinese medicine can inhibit CRC cell proliferation， invasion， metastasis， angiogenesis， and inflammation by modulating the NF-κB signaling pathway， induce cell apoptosis， restore drug and radiation sensitivity， and counteract CRC. This article is expected to provide insights and references for the in-depth exploration and treatment of CRC mechanisms.

Dahuang Mudantang Alleviates Intestinal Injury in Rat Model of Acute Pancreatitis by Regulating HMGB1/RAGE/NF-κB Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo explore the mechanism of Dahuang Mudantang in alleviating the intestinal injury in the rat model of acute pancreatitis via the high-mobility group box 1 （HMGB1）/receptor for advanced glycation endproduct （RAGE）/nuclear factor-κB （NF-κB） signaling pathway. MethodOne hundred and twenty SPF-grade Wistar rats received retrograde injection of 5% sodium taurocholate into the biliopancreatic duct for the modeling of intestinal injury in acute pancreatitis. The rats were randomized into blank， model， low-， medium-， and high-dose （3.5， 7， 14 g·kg-1， administrated by gavage） Dahuang Mudantang， and octreotide （1×10-5 g·kg-1， subcutaneous injection） groups （n=20）. The rats in blank and model groups received equal volume of distilled water by gavage. Drugs were administered 1 h before and every 12 h after modeling， and samples were collected 24 h after modeling. The general status of the rats was observed. The biochemical methods were employed to measure the levels of amylase （AMS） and C-reactive protein （CRP） in the serum. The enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and IL-6 in the colon tissue. The morphological changes of pancreatic and colon tissues were observed by hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to measure the expression levels of HMGB1， RAGE， inhibitor of NF-κB kinase （IKK）， and NF-κB suppressor protein α（IκBα）in the colon tissue. ResultThe rats in the model group showed poor general survival， writhing response， reduced frequency of defecation， and dry stool. The symptoms of rats in the model group were mitigated in each treatment group， and the high-dose Dahuang Mudantang showed the most significant effect. Compared with the normal group， the model group had elevated AMS and CRP levels （P<0.05）， which were lowered by Dahuang Mudantang （P<0.05）， especially that at the high dose （P<0.05）. Compared with the normal group， the modeling elevated that levels of TNF-α， IL-1β， and IL-6 （P<0.05）. Such elevations were lowered by Dahuang Mudantang （P<0.05）， and the high-dose group and the octreotide group showed better performance （P<0.05）. The modeling caused necrotic， congested， and destructed pancreatic and colonic tissues， which were ameliorated by the drugs， especially high-dose Dahuang Mudantang. Compared with the normal group， the modeling up-regulated the mRNA levels of HMGB1， RAGE， IKK， IκBα， and NF-κB （P<0.05）. Compared with the model group， Dahuang Mudantang and octreotide down-regulated the mRNA levels of HMGB1， RAGE， IKK， IκBα， and NF-κB （P<0.05）， and the high-dose Dahuang Mudantang demonstrated the best performance （P<0.05）. Western blot results showed a trend consistent with the results of Real-time PCR. ConclusionDahuang Mudantang can improved the general status， reduce inflammation， and alleviate histopathological changes in the pancreatic and colon tissues in the rat model of acute pancreatitis by inhibiting the HMGB1/RAGE/NF-κB signaling pathway.

Aucubin combined with ADSCs-exos protects TBHP-induced nucleus pulposus cells via TLR4/NF-κB pathway / 中国中药杂志

This paper aims to investigate the effects and mechanisms of adipose-derived stem cells-exosomes(ADSCs-exos) toge-ther with aucubin in protecting human-derived nucleus pulposus cells(NPCs) from inflammatory injury, senescence, and apoptosis. The tert-butyl hydroperoxide(TBHP)-induced NPCs were assigned into normal, model, aucubin, ADSCs-exos, and aucubin+ADSCs-exos groups. The cell viability was examined by cell counting kit-8(CCK-8), cell proliferation by EdU staining, cell senescence by senescence-associated-β-galactosidase(SA-β-Gal), and cell cycle and apoptosis by flow cytometry. Enzyme-linked immunosorbent assay was employed to examine the expression of interleukin-1β(IL-1β), IL-10, and tumor necrosis factor-α(TNF-α). Real-time fluorescence quantitative PCR and Western blot were employed to determine the mRNA and protein levels of aggregated proteoglycan(aggrecan), type Ⅱ collagen alpha 1(COL2A1), Toll-like receptor 4(TLR4), and nuclear factor-kappa B(NF-κB). The results showed that compared with the model group, the aucubin or ADSCs-exos group showed enhanced viability and proliferation of NPCs, decreased proportion of G_0/G_1 phase cells, increased proportion of S phase cells, reduced apoptosis and proportion of cells in senescence, lowered IL-1β and TNF-α levels, elevated IL-10 level, down-regulated mRNA and protein levels of TLR4 and NF-κB, and up-regulated mRNA and protein levels of aggrecan and COL2A1. Compared with the aucubin or ADSCs-exos group, the aucubin+ADSCs-exos combination further increased the viability and proliferation of NPCs, decreased the proportion of G_0/G_1 phase cells, increased the proportion of S phase cells, reduced the apoptosis and proportion of cells in senescence, lowered the IL-1β and TNF-α levels, elevated the IL-10 level, down-regulated the mRNA and protein levels of TLR4 and NF-κB, and up-regulated the mRNA and protein levels of aggrecan and COL2A1. In summary, both aucubin and ADSCs-exos could exert protective effects by inhibiting inflammatory responses, reducing apoptosis and senescence of NPCs, improving cell viability and proliferation as well as extracellular matrix synthesis, which may be associated with the inhibition of TLR4/NF-κB signaling pathway activation. The combination of both plays a synergistic role in the protective effects.

Mechanism of Buyang Huanwu Decoction glycosides against atherosclerotic inflammation through NF-κB signaling pathway / 中国中药杂志

This study aims to explore the effect of Buyang Huanwu Decoction glycosides on the inflammatory response of apolipoprotein E~(-/-)(ApoE~(-/-)) mice and RAW264.7 cells through nuclear factor kappa-B(NF-κB) signaling pathway. In the in vivo experiment, ApoE~(-/-) mice were fed with high-fat diets for 12 weeks to induce the animal model of atherosclerosis, and 75 μg·mL~(-1) oxidized low-density lipoprotein(Ox-LDL) incubated RAW264.7 cells for 24 h to establish the atherosclerosis cell model. Automatic biochemical analyzer, hematoxylin-eosin(HE) staining, enzyme-linked immunosorbent assay(ELISA), Western blot, and droplet digital polymerase chain reaction(PCR) were used to determine the blood lipid levels, aortic intimal thickness, inflammatory factor content, NF-κB pathway-related proteins, and mRNA expression levels, and evaluate arterial atherosclerotic lesions and anti-atherosclerotic mechanisms of the drug. The model of atherosclerosis was successfully established in ApoE~(-/-) mice after 12 weeks of feeding with high-fat diets. In the model group, the plasma levels of total cholesterol(TC), triglyceride(TG), and low-density lipoprotein cholesterol(LDL-C) were increased(P<0.01), the intima of the blood vessels was thickened, the levels of inflammatory factors tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) were increased, and the protein and mRNA expressions of NF-κB and inhibitor of NF-κB(IκBα) were significantly increased as compared with the control group. Compared with the model group, the high-dose Buyang Huanwu Decoction glycoside group decreased the plasma levels of TC, TG, and LDL-C, reduced the plaque area and thickness and the content of inflammatory factor TNF-α, and inhibited the protein and mRNA expressions of NF-κB and IκBα, with the effect same as Buyang Huanwu Decoction. In the in vivo experiment, 75 μg·mL~(-1) Ox-LDL stimulated RAW264.7 cells for 24 h to successfully establish a foam cell model. As compared with the control group, the nuclear amount of NF-κB and the protein and mRNA expressions of IκBα in the model group increased. Compared with the model group, the middle-dose and high-dose Buyang Huanwu Decoction glycoside groups decreased the nuclear amount of NF-κB and the protein and mRNA expressions of IκBα. The above results show that the glycosides are the main effective substances of Buyang Huanwu Decoction against atherosclerosis, which inhibit the NF-κB pathway and reduce the inflammatory response, thus playing the role against atherosclerotic inflammation same as Buyang Huanwu Decoction.
