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.

Wilson's Disease in Traditional Chinese and Western Medicine： A Review / 中国实验方剂学杂志

Wilson's disease （WD） is a copper metabolism disorder caused by mutations in the ATP7B gene， with diverse phenotypes and complex pathogenesis. It is one of the few rare diseases that can achieve good clinical efficacy through standardized treatment. Since there are few systematic reviews of this disease， we summarize the pathogenesis and treatment methods of WD from traditional Chinese and western medicine by reviewing the literature related to WD. In western medicine， ATP7B gene mutation is considered as the root cause of WD， which affects copper transport and causes copper metabolism disorders. The excessive copper deposited in the body will result in oxidative stress， defects in mitochondrial function， and cell death. Western medicine treatment of WD relies mainly on drugs， and copper antagonists are the first choice in clinical practice， which are often combined with hepatoprotective and antioxidant therapy. Surgery is a common therapy for the patients with end-stage WD， and gene therapy provides an option for WD patients. According to the traditional Chinese medicine （TCM） theory， WD is rooted in constitutional deficiency and copper accumulation and triggered by dampness-heat accumulation or phlegm combined with stasis. The patient syndrome varies in different stages of the disease， and thus the treatment should be based on syndrome differentiation. The TCM treatment method of nourishing the liver and kidneys and warming the spleen and kidneys can address the root cause. The methods of clearing heat and drying dampness， resolving phlegm and dispelling stasis， and soothing liver and regulating qi movement can be adopted to treat symptoms. On the basis of syndrome differentiation， special prescriptions for the treatment of WD have been formulated， such as Gandou decoction， Gandouling， and Gandou Fumu decoction， which have been widely used in clinical practice. TCM and western medicine have their own advantages and shortcomings. The integrated Chinese and western medicine complementing with each other demonstrates great therapeutic potential. This paper summarizes the pathogenesis and treatment of WD with integrated Chinese and western medicine， aiming to provide a reference for the clinical diagnosis and treatment of this disease.

Interleukin-6 in Skeletal Muscle Mass Regulation / 中国生物化学与分子生物学报

Interleukin-6 (IL-6) is a spreading pleiotropic cytokine, with both anti-inflammatory and proinflammatory effects. It not only participates in the body immune responses but also is involved in the biological regulative processes among different organs, tissues, and cells. IL-6 has both anti-inflammatory and pro-inflammatory effects. In the early stage of pathogen infection, IL-6 plays an anti-inflammatory role in the body, and its level is moderately increased in the body to resist inflammation and maintain internal homeostasis. However, a large amount of IL-6 release can cause excessive inflammation and trigger other pathological changes in the body. Il-6 also has the dual effect of stimulating the synthesis and degradation of skeletal muscle protein in regulating skeletal muscle mass. As an important locomotive organ, skeletal muscle is also one of the key targets of IL-6. IL-6 takes part in the biological control of skeletal muscle hypertrophy through regulating muscle satellite cell proliferation and differentiation under specific stresses. In addition IL-6 is also associated with skeletal muscle atrophy induced by aging and other pathological stresses. In addition, during exercise stress, skeletal muscle can also serve as an endocrine organ to secrete and release IL-6 that facilitates the "crosstalk" between skeletal muscle and other organs or tissues. As IL-6 plays as a versatile role in our body, this paper reviews the research progress of the mechanism of IL-6 in the regulation of skeletal muscle mass, which may provide theoretical support for revealing the molecular mechanism of skeletal muscle stresses and adaptations.

Research progress on Astragalus active ingredient in treatment of hepatic fibrosis based on cell signaling pathway / 中国药理学通报

Hepatic fibrosis is present in most chronic liver disease processes, and there are no ideal anti-fibrotic drugs available. Astragalus has a long history of medicinal use, and its anti-fibrotic effects have been confirmed by modern studies. In this study we have searched the literature to identify the signaling pathways and mechanisms of action of Astragalus and its active ingredients on hepatic fibrosis in recent years, so as to provide the basis and ideas for the development of anti-fibrotic drugs and mechanisms of Astragalus. It is showed that the active ingredients of Astragalus act through regulating p38MAPK, TGF-pl/Smads,NF-

MANF brakes TLR4 signaling by competitively binding S100A8 with S100A9 to regulate macrophage phenotypes in hepatic fibrosis

The mesencephalic astrocyte-derived neurotrophic factor (MANF) has been recently identified as a neurotrophic factor, but its role in hepatic fibrosis is unknown. Here, we found that MANF was upregulated in the fibrotic liver tissues of the patients with chronic liver diseases and of mice treated with CCl4. MANF deficiency in either hepatocytes or hepatic mono-macrophages, particularly in hepatic mono-macrophages, clearly exacerbated hepatic fibrosis. Myeloid-specific MANF knockout increased the population of hepatic Ly6Chigh macrophages and promoted HSCs activation. Furthermore, MANF-sufficient macrophages (from WT mice) transfusion ameliorated CCl4-induced hepatic fibrosis in myeloid cells-specific MANF knockout (MKO) mice. Mechanistically, MANF interacted with S100A8 to competitively block S100A8/A9 heterodimer formation and inhibited S100A8/A9-mediated TLR4-NF-κB signal activation. Pharmacologically, systemic administration of recombinant human MANF significantly alleviated CCl4-induced hepatic fibrosis in both WT and hepatocytes-specific MANF knockout (HKO) mice. This study reveals a mechanism by which MANF targets S100A8/A9-TLR4 as a "brake" on the upstream of NF-κB pathway, which exerts an impact on macrophage differentiation and shed light on hepatic fibrosis treatment.

Discovery of an orally effective double-stapled peptide for reducing ovariectomy-induced bone loss in mice

Stapled peptides with significantly enhanced pharmacological profiles have emerged as promising therapeutic molecules due to their remarkable resistance to proteolysis and performance to penetrate cells. The all-hydrocarbon peptide stapling technique has already widely adopted with great success, yielding numerous potent peptide-based molecules. Based on our prior efforts, we conceived and prepared a double-stapled peptide in this study, termed FRNC-1, which effectively attenuated the bone resorption capacity of mature osteoclasts in vitro through specific inhibition of phosphorylated GSK-3β. The double-stapled peptide FRNC-1 displayed notably improved helical contents and resistance to proteolysis than its linear form. Additionally, FRNC-1 effectively prevented osteoclast activation and improved bone density for ovariectomized (OVX) mice after intravenous injection and importantly, after oral (intragastric) administration. The double-stapled peptide FRNC-1 is the first orally effective peptide that has been validated to date as a therapeutic candidate for postmenopausal osteoporosis (PMOP).

A Survey of the Current Status of Surgical Treatment of Hemophilic Osteoarthropathy in China Mainland 17 Grade A General Hospitals / 罕见病研究

  Objective  To understand the current status of surgical treatment for hemophilia osteoarthropathy (HO) in China.  Methods  Using an online questionnaire, select domestic hospitals that partici-pated in the compilation of the 'Guideline for perioperative management of hemophilia patients undergoing orthopaedic surgery in China ', in addition to members of the National Joint Surgery Group, and the Orthopedic Branch of the Chinese Medical Association for targeted investigation and analysis.  Results  A total of 17 domestic hospitals were included, all of which were general hospitals. Hospitals that started HO surgery treatment before 2000 accounted for 35.29%. A total of 3057 surgical cases of HO were reported by those hospitals. The most commonly performed surgical procedures were hip and knee joint replacement. The most commonly used coagulation factor replacement regimen was recombinant coagulation factor preparation. Ten hospitals reported finding patients with transfusion-related infectious diseases. Bleeding and hematoma formation were the most frequently reported surgical complications. Excessive length of hospital stay and high economic costs were the most frequently reported problems.  Conclusions  Surgical treatment for HO in 17 hospitals is mainly carried out in some large comprehensive medical centers in the eastern region. Compared with the patient base, the popularity and number of surgeries are still relatively insufficient. It is necessary to further standardize the treatment system by standardizing factor replacement and strengthening rehabilitation to improve surgical treatment outcomes.

Estimation of the effective radiation dose for tunnel construction workers / 中国职业医学

Objective To analyze and set up the effective dose of different ionizing radiation for tunnel construction workers. Methods A total of five tunnels constructed using drilling and blasting methods were selected as the research subjects using the convenient sampling method. The workplace γ radiation effective dose, radon concentrations, and radioactive activity concentrations were detected, and on-site surveys were conducted to estimate the internal and external irradiation doses and total effective doses for workers in different work sites. Results Radiological hazards in tunnels constructed using drilling and blasting methods included radon and its progeny, γ radiation, radioactive dust (uranium-238, radium-226, thorium-232, and potassium-40) and others. The average total effective dose of ionizing radiation exposure for tunnel construction workers was (6.730 1±1.541 1) mSv. The average dose of radon and its progeny was (6.163 0±1.512 8) mSv, radioactive dust was (0.014 6±0.009 1) mSv, γ radiation was (0.552 6±0.138 7) mSv. The dose of radioactive dust of radon and its progeny was 0.24%. Radon and its progeny contributed more to the radioactive dose than radioactive dust and γ radiation (all P<0.05). Among all the radioactive dusts, the dose contribution ranked from highest to lowest was thorium-232, uranium-238, and radium-226. Conclusion For tunnel construction workers, the largest contribution to the effective dose of ionizing radiation exposure is from radon and its progeny for internal irradiation, followed by γ radiation for external irradiation. The contribution of radioactive dust to internal irradiation dose can be considered negligible.

Intervention Effect of Gandou Fumu Decoction on Renal Fibrosis in TX Mice Through JAK/STAT Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the protective effect and underlying mechanism of Gandou Fumu decoction （GDFMT） on renal fibrosis in a mouse model of Wilson's disease. MethodSixty adult male toxic milk （TX） mice were randomly divided into a model group， high-， medium-， and low-dose GDFMT groups， and a positive control （penicillamine） group， and another 12 wild-type mice were assigned to the normal group. The high-， medium-， and low-dose GDFMT groups were administered GDFMT at 13.92， 6.96， 3.48 g·kg-1， respectively， and the positive control group received penicillamine at 0.1 g·kg-1， while the model and normal groups were given an equal volume of 0.9% saline solution by gavage once a day for 4 consecutive weeks. Enzyme-linked immunosorbent assay （ELISA） was used to measure the levels of blood urea nitrogen （BUN）， creatinine （CRE）， type Ⅲ procollagen （PC-Ⅲ）， and type Ⅳ collagen （C-Ⅳ） in the serum. Histological changes in the mouse kidneys were examined by hematoxylin-eosin （HE） and Masson's trichrome staining. Immunofluorescence was used to assess the protein expression of leptin， Janus kinase 2 （JAK2）， and signal transducer and activator of transcription （STAT） in renal cells. Real-time polymerase chain reaction （Real-time PCR） was performed to analyze the mRNA expression levels of leptin， leptin receptor（OB-R）， JAK2， and STAT. Western blot was used to detect the expression of transforming growth factor-β1 （TGF-β1） and monocyte chemoattractant protein-1 （MCP-1）. ResultCompared with the normal group， the model mice exhibited a significant increase in BUN， CRE， PC-Ⅲ， and C-Ⅳ levels （P<0.01）. Compared with the model group， the high- and medium-dose GDFMT groups and the penicillamine groups showed significant decreases in these parameters （P<0.05， P<0.01）， with the high-dose GDFMT group demonstrating the most significant reduction （P<0.01）. The histological examination of renal tissue revealed fibrosis in the model group， while the fibrotic damage was mitigated to varying degrees after drug intervention， with improvement in fibrosis. Immunofluorescence results showed that leptin， JAK2， and STAT3 protein expression levels were significantly upregulated in the renal fibrosis of the model group. After GDFMT intervention， the fluorescence intensity decreased， with the high-dose GDFMT group showing the lowest intensity. Real-time PCR results demonstrated that leptin， OB-R， JAK2， and STAT3 mRNA expression levels were significantly elevated in the model group compared with those in the normal group， while the high- and medium-dose GDFMT groups and the penicillamine group showed significant reductions in their expression levels （P<0.05， P<0.01）. Western blot analysis revealed that TGF-β1 and MCP-1 expression levels were significantly increased in the model group （P<0.01）， and the high- and medium-dose GDFMT groups exhibited significant reductions in their expression levels （P<0.01）. ConclusionGDFMT can alleviate renal fibrosis damage in TX mice， and its mechanism of action may be related to the regulation of leptin and the JAK/STAT signaling pathway.

Da Chengqitang in Treatment of Sepsis： A Review / 中国实验方剂学杂志

Sepsis is a systemic inflammatory syndrome induced by infection and other factors， with the number of patients worldwide exceeding 10 million each year. The pathophysiological mechanism is of this disease complex. Sepsis is often accompanied by endotoxin translocation， gastrointestinal dysfunction， inflammatory cytokine activation， immune dysregulation， coagulation disorder， multiple organ function impairment and many other body imbalances， as well as systemic inflammation， apoptosis， oxidative stress injury and other cell damage mechanisms. This disease causes a heavy medical burden due to the difficult diagnosis and treatment and the poor prognosis. Great progress has been achieved in the diagnosis and treatment of sepsis with traditional Chinese medicine （TCM） and western medicine. The value of western medicine in the diagnosis and treatment of sepsis is limited due to antibiotic resistance， hormone abuse， and high medical costs. Sepsis is classified as a warm disease or typhoid fever in TCM. Da Chengqitang is a classical formula in the Treatise on Typhoid Fever to deal with the excess syndrome of Yang brightness Fu-organ. Modern medicine has proved that Da Chengqitang has the effect of inhibiting oxidative stress， reducing inflammation， and delaying apoptosis by improving gastrointestinal dynamics and regulating intestinal microecology. On the basis of the previous theoretical basis and the rich experience in the medication， medical practitioners have proposed a new therapeutic concept of using Da Chengqitang in combination with western drugs from a holistic view involving both bacteria and toxicity for treating both the symptoms and the root cause， which has a wide range of application. The article reviews the classical research and latest findings of Da Chengqitang in the treatment of sepsis， with a view to clarifying the mechanism and advantages of this formula in the adjuvant treatment of sepsis， exploring its potential efficacy， and providing timely， adequate， and scientific theoretical support for the promotion of this formula in the clinical practice.

Research progress on influencing factors of depressive symptoms in adolescents / 中国学校卫生

Abstract@#In recent years, mental health problems such as anxiety and depression among adolescents in China have attracted attention from all walks of life. Given that adolescence is a transitional and critical period for individual development, mental health affect the developmental opportunities. Therefore, in the review, the effects of environment, psychosocial factors and behavioral patterns on depressive symptoms are analyzed by combining with the characteristics of physical and mental development among adolescents. It is found that early adolescence and even childhood should be the key period for the prevention and intervention of depression. In order to formulate effective interventions and prevention strategies, it is proposed that future research should combine real situation in China with active exploration of protective factors and early predictors of depression.

After adjusting for gender and age in the Logistic regression model, compared with those with high PFI, the risk of depressive symptoms in those with low PFI was 1.18 times (95% CI =1.05-1.33).@*Conclusion@#There is a correlation between physical fitness and depressive symptoms in adolescents. Adolescents with low PFI are at higher risk of developing depressive symptoms than those with high PFI.

Clinical Significance of co-expression of RNA Binding Protein PTBP1 and p-AXL in Osteosarcoma / 中山大学学报(医学科学版)

ObjectiveTo explore the co-expression of PTBP1 and p-AXL in osteosarcoma and its clinicopathological significance for prognosis evaluation. MethodsThe expression of PTBP1 and AXL and their prognostic value in osteosarcoma were analyzed by GEO and Target data. Paraffin biopsy specimens and clinical information from 76 cases of osteosarcoma and 37 cases of non-malignant bone tissue （callus， osteofibrous dysplasia and osteoid ostema） were obtained from the First Affiliated Hospital of Sun Yat-sen University from March 2016 to October 2020. The expressions of PTBP1 and p-AXL proteins in osteosarcoma were detected by immunohistochemistry. ResultsGEO database showed that the expression levels of PTBP and AXL in osteosarcoma tumor group were higher than those in normal tissues， but did not reach statistical significance. Target database showed that the high expression of PTBP1 had shorter Overall survival（OS） and Progression-free survival（PFS） than low PTBP1 expression， but did not reach statistical significance （P=0.064； P=0.134）. Immunohistochemical staining included 76 cases of osteosarcoma and 37 cases of non-malignant bone tissue. The expression rate of PTBP1 and p-AXL protein in osteosarcoma tissues was higher than that in non-malignant bone tissue. The expression of p-AXL is correlated with lung metastasis （P=0.025）. Kaplan-Meier analysis showed that lung metastasis， recurrence， PTBP1 expression， co-expression of PTBP1/p-AXL influence the prognosis of patients in OS. Multivariate Cox regression analysis showed that lung metastasis （P<0.000 1） and positive expression of PTBP1 （P=0.041） were independent risk factors for osteosarcoma patients in OS. Co-expression of PTBP1 and p-AXL had shorter OS （P=0.017） and PFS （P=0.043） than non-coexpression osteosarcoma patients. ConclusionsPTBP1 and p-AXL were highly expressed in osteosarcoma tissues. The co-expression of PTBP1 and p-AXL was associated with poor prognosis of patients， and PTBP1 could be used as an independent prognostic indicator of patients with osteosarcoma.

There was no significant difference in Harris score between 3 months after operation and the final follow-up in both groups (P>0.05). There were no significant difference in VAS scores of 6 weeks after operation and on the final follow-up neither(P>0.05). The level of creatine kinase in SuperCap group was significant lower than that in DAA group(P<0.05). Until the final follow-up, there was no significant difference in the incidence of complications between the two groups(P>0.05).@*CONCLUSION@#The clinical effect of minimally invasive SuperCap approach after total hip arthroplasty is comparable to that of DAA approach with less soft tissue injury. Patients can recover rapidly after operation and it is a safe and effective surgical approach for surgeons with short learning curve.

Effectiveness of Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor in treatment of Cho type ⅡC distal clavicle fractures / 中国修复重建外科杂志

OBJECTIVE@#To evaluate the effectiveness of Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures.@*METHODS@#The data of 17 patients with Cho type ⅡC distal clavicular fractures, who were treated with Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor between June 2019 and June 2021, was retrospectively analyzed. There were 11 males and 6 females with an average age of 38.7 years (range, 19-72 years). The fractures were caused by falling in 12 cases and traffic accident in 5 cases. All patients had fresh closed fractures. The interval from injury to operation was 1-5 days (mean, 2.6 days). The preoperative injury severity score (ISS) was 6-27 (mean, 10.2). The operation time, intraoperative blood loss, hospital stay, fracture healing, and postoperative complications were analyzed. The shoulder joint function was evaluated by disabilities of the arm, shoulder, and hand (DASH) score and Constant score at last follow-up.@*RESULTS@#All operations were completed successfully. The operation time was 20-50 minutes (mean, 31.6 minutes). The intraoperative blood loss was 30-100 mL (mean, 50.6 mL). The hospital stay was 4-9 days (mean, 5.3 days). All incisions healed by first intention. All patients were followed up 12-16 months (mean, 13 months). All clavicle fractures healed, and the healing time was 8-15 weeks (mean, 11 weeks). No complications such as fracture displacement or nonunion caused by internal fixation failure occurred. During the follow-up, skin irritation caused by the Kirschner wire withdrawal occurred in 3 cases. The Kirschner wires were removed after fracture healing in 17 patients. At last follow-up, the Constant score of shoulder joint was 90-100 (mean, 98.2). The DASH score was 0-10 (mean, 1.5).@*CONCLUSION@#Kirschner wire fixation combined with coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures has less postoperative complications and slight complications. It is convenient to remove the internal fixator. The Kirschner wire does not fix the distal clavicle fracture through the acromion, which has little effect on shoulder joint function and can obtain good effectiveness.

Chemical and nutrient differences between medicinal material, residues, and residue compost of Moutan Cortex / 中国中药杂志

Moutan Cortex(MC) residues produced after the extraction of MC can be re-extracted for active components and used to produce organic fertilizer and animal feed. However, they are currently disposed as domestic waste, which pollutes the environment. This study analyzed the chemical composition of the medicinal material, residues, and residue compost of MC by UPLC-UV-Q-TOF-MS. Furthermore, the nutrient composition of MC residues and the residue compost was analyzed. The results showed that:(1)MC residues had lower content of chemicals than the medicinal material, and content of paeonol, gallic acid, and galloylglucose in MC residues were about 1/3 of that in the medicinal material. The content of chemicals were further reduced after residue composting, and the quantitative compounds were all below the limits of detection.(2)Compared with MC residues, the residue compost showed the total nitrogen, total phosphorus, total potassium, and organic matter content increasing by 122.67%, 31.32%, 120.39%, and 32.06%, respectively. Therefore, we concluded that the MC residues can be used to re-extract active compounds such as paeonol, gallic acid, and galloylglucose. The MC residue compost is a high-quality organic fertilizer containing minimal content of chemicals and can be widely used in the cultivation of Chinese medicinal herbs.

The suppression of cervical cancer ferroptosis by macrophages: The attenuation of ALOX15 in cancer cells by macrophages-derived exosomes

Induction of cancer cell ferroptosis has been proposed as a potential treatment in several cancer types. Tumor-associated macrophages (TAMs) play a key role in promoting tumor malignant progression and therapy resistance. However, the roles and mechanisms of TAMs in regulating tumor ferroptosis is still unexplored and remains enigmatic. This study shows ferroptosis inducers has shown therapeutic outcomes in cervical cancer in vitro and in vivo. TAMs have been found to suppress cervical cancer cells ferroptosis. Mechanistically, macrophage-derived miRNA-660-5p packaged into exosomes are transported into cancer cells. In cancer cells, miRNA-660-5p attenuates ALOX15 expression to inhibit ferroptosis. Moreover, the upregulation of miRNA-660-5p in macrophages depends on autocrine IL4/IL13-activated STAT6 pathway. Importantly, in clinical cervical cancer cases, ALOX15 is negatively associated with macrophages infiltration, which also raises the possibility that macrophages reduce ALOX15 levels in cervical cancer. Moreover, both univariate and multivariate Cox analyses show ALOX15 expression is independent prognostic factor and positively associated with good prognosis in cervical cancer. Altogether, this study reveals the potential utility of targeting TAMs in ferroptosis-based treatment and ALOX15 as prognosis indicators for cervical cancer.

Network pharmacology approaches for research of Traditional Chinese Medicines / 中国天然药物

Pharmacodynamics material basis and effective mechanisms are the two main issues to decipher the mechnisms of action of Traditional Chinese medicines (TCMs) for the treatment of diseases. TCMs, in "multi-component, multi-target, multi-pathway" paradigm, show satisfactory clinical results in complex diseases. New ideas and methods are urgently needed to explain the complex interactions between TCMs and diseases. Network pharmacology (NP) provides a novel paradigm to uncover and visualize the underlying interaction networks of TCMs against multifactorial diseases. The development and application of NP has promoted the safety, efficacy, and mechanism investigations of TCMs, which then reinforces the credibility and popularity of TCMs. The current organ-centricity of medicine and the "one disease-one target-one drug" dogma obstruct the understanding of complex diseases and the development of effective drugs. Therefore, more attentions should be paid to shift from "phenotype and symptom" to "endotype and cause" in understanding and redefining current diseases. In the past two decades, with the advent of advanced and intelligent technologies (such as metabolomics, proteomics, transcriptomics, single-cell omics, and artificial intelligence), NP has been improved and deeply implemented, and presented its great value and potential as the next drug-discovery paradigm. NP is developed to cure causal mechanisms instead of treating symptoms. This review briefly summarizes the recent research progress on NP application in TCMs for efficacy research, mechanism elucidation, target prediction, safety evaluation, drug repurposing, and drug design.
