Many commensal or pathogenic bacteria interact with their hosts through biochemical signals. Based on these bacterial properties, commensal and attenuated pathogens have been designed to deliver therapeutic molecules to target specific diseases. The engineered bacteria or bacteria-derived particles and their encapsulation, secretion, and expression of surface therapeutic molecules developed in the past five years were introduced. Their applications in anti-inflammatory, anti-tumor, thrombosis treatment, and imaging were reviewed, and the clinical translational potential of microbial drug delivery systems was discussed.

Interpretation of the Chinese expert consensus on treatment of non-infectious uveitis with anti-tumor necrosis factor-alpha monoclonal antibody / 中华眼底病杂志

As a new treatment option after conventional corticosteroids and immunomodulatory drugs, biologics have been widely used in the clinical management of non-infectious uveitis in many countries due to their approved efficacy and safety. Anti-tumor necrosis factor-alpha monoclonal antibody is the most commonly used one. However, the guidance on its standardized application is lacking. The Ocular Immunology Group of Immunology and Rheumatology Academy in Cross-Straits Medicine Exchange Association compiled the Chinese expert consensus on treatment of non-infectious uveitis with anti-tumor necrosis factor-alpha monoclonal antibody. This evidence-based consensus is made according to the principle of consensus building and combines the clinical experience of the experts. Twelve recommendations are formatted on the application of Adalimumab and Infliximab. The interpretation of this consensus point will help improve the normative and effective application of anti-tumor necrosis factor-alpha monoclonal antibody in ophthalmologists, rheumatologists and immunologists.

Screening Effective Sites of Momordicae Semen-Epimedii Folium and Anti-lung Cancer Mechanism of Its Prescription / 中国实验方剂学杂志

ObjectiveTo preliminarily confirm the effective anti-lung cancer sites of Momordicae Semen and Epimedii Folium and study their mechanism of action. MethodOn the basis of preliminary research， the extraction method of Momordicae Semen and Epimedii Folium was optimized and the effective parts were screened under the guidance of pharmacological effects. Different ethanol elution and water elution sites of Momordicae Semen and Epimedii Folium were obtained through adsorption and elution with D101 macroporous resin. The methylthiazolyldiphenyl-tetrazolium bromide （MTT） colorimetric assay was used to detect the effects of total drug extracts and different elution sites on the proliferation of various tumor cell lines， and to screen for the optimal elution site and tumor sensitive strains. Flow cytometry was used to detect the effect of the elution sites of Momordicae Semen and Epimedii Folium on intracellular reactive oxygen species （ROS） and apoptosis in A549 cells. Western blot was used to compare the expressions of tumor protein 53 （p53）， Bcl-2-associated X protein （Bax）， cysteinyl aspartate specific proteinase-3 and 9 （Caspase-3 and Caspase-9） proteins in A549 cells. ResultThe inhibitory effect of Momordicae Semen on the proliferation of A549 cells was better than the kernel of Momordicae Semen， with 50% inhibitory concentration （IC50） being （86.83±2.88） mg·L-1 and （95.10±18.13） mg·L-1， respectively. The effect of total extracts of Epimedii Folium on A549 anti proliferation IC50 value was （4.71±0.81） mg·L-1. The IC50 values of the 40%， 60%， and 80% ethanol and anhydrous ethanol eluted macroporous resins of the total extracts of Momordicae Semen and Epimedii Folium inhibiting A549 proliferation were （45.32±4.38）、 （14.95±0.73）、 （17.07±1.76）、 （14.46±2.35）、 （51.7±2.26）、 （12.37±0.67）、 （20.29±0.93）、 and （3.43±0.91） mg·L-1， respectively. Compared with the normal group， the 1∶1 combination of Momordicae Semen and Epimedii Folium inhibited A549 cell proliferation in a time-dependent and concentration-dependent manner. Compared with the normal group， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased intracellular ROS expression （P<0.01）. Compared with the normal group， 12.5， 25， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of A549 cell apoptosis （P<0.01）. Compared with the normal group， 25， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of p53 in A549 cells （P<0.01）. Compared with the normal group， 12.5， 25， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of Bax （P<0.01）. Compared with the normal group， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly reduced the expressions of Caspase-3 and Caspase-9 （P<0.01）. ConclusionThe anti-tumor effect of Momordicae Semen is better than that of the kernel of Momordicae Semen. The anti-tumor substances of Momordicae Semen and Epimedii Folium mainly concentrate in the 60% ethanol to anhydrous ethanol elution site. A549 cells are sensitive to the 1∶1 combination of Momordicae Semen and Epimedii Folium， which can effectively inhibit the cell proliferation. The mechanism may be related to increasing the generation of ROS in A549 cells， promoting their apoptosis， increasing the expressions of apoptotic proteins such as p53 and Bax， and reducing the expressions of Caspase-3 and Caspase-9.

Research progress on mitochondria regulating anti-tumor immunity / 浙江大学学报·医学版

Tumor cells adaptively reforge their metabolism to meet the demands of energy and biosynthesis. Mitochondria, pivotal organelles in the metabolic reprogramming of tumor cells, contribute to tumorigenesis and cancer progression significantly through various dysfunctions in both tumor and immune cells. Alterations in mitochondrial dynamics and metabolic signaling pathways exert crucial regulatory influence on the activation, proliferation, and differentiation of immune cells. The tumor microenvironment orchestrates the activation and functionality of tumor-infiltrating immune cells by reprogramming mitochondrial metabolism and inducing shifts in mitochondrial dynamics, thereby facilitating the establishment of a tumor immunosuppressive microenvironment. Stress-induced leakage of mitochondrial DNA contributes multifaceted regulatory effects on anti-tumor immune responses and the immunosuppressive microenvironment by activating multiple natural immune signals, including cGAS-STING, TLR9, and NLRP3. Moreover, mitochondrial DNA-mediated immunogenic cell death emerges as a promising avenue for anti-tumor immunotherapy. Additionally, mtROS, a crucial factor in tumorigenesis, drives the formation of tumor immunosuppressive microenvironment by changing the composition of immune cells within the tumor microenvironment. This review focuses on the intrinsic relationship between mitochondrial biology and anti-tumor immune responses from multiple angles. We expect to explore the core role of mitochondria in the dynamic interplay between the tumor and the host, in order to facilitate the development of targeted mitochondrial strategies for anti-tumor immunotherapy.

Objective By analyzing the anti-tumor innovative drug policies text in China,this study aimed to explore the focus and shortcomings of policies related to anti-tumor innovative drugs,and provide the reference for future policy formula-tion and optimization in the field of anti-tumor innovative drug.Methods By accessing the official websites of relevant minis-tries and subordinate institutions such as the Central Committee of the Communist Party of China,the State Council of the People's Republic of China,the National Health Commission of the People's Republic of China,and National Medical Products Administra-tion,and using the keywords"cancer","tumor","anti-tumor drug",and"innovative drug",etc,the national level policies related to the anti-tumor innovative drugs from January 1,2005,to December 31,2022,were collected.Based on a two-dimensional analy-sis framework of policy tools and stakeholders,the collected policy texts were classified,encoded,and statistically analyzed.Results A total of 30 policy texts were involved,and a total of 90 policy codes were generated.There were 24,43,and 23 codes for demand-based policy tools,environmental policy tools,and supply-based policy tools,accounting for 26.67%,47.78%,and 25.56%,respectively.Based on policy tools and stakeholders,a total of 183 codes were generated,with government departments,pharmaceutical enterprises,medical institutions,and patients having 70,36,54,and 23 codes respectively,accounting for 38.25%,19.67%,29.51%,and 12.57%.Conclusions China had the highest proportion of environmental policy tools in the application of innovative anti-tumor drug policies,while supply-oriented and demand-oriented policy tools were underutilized,resulting in an overall imbalance in application;The distribution pattern of stakeholders was not coordinated,with government departments and medical institutions having higher attention than pharmaceutical enterprises and patients..It was necessary to reasonably promote the collaborative application of anti-tumor innovative drug policy tools,scientifically plan the layout of anti-tumor innovative drug policy sub-tools,and balance the interests of all stakeholders to ensure the efficient implementation of the policies.

Effect of LPS-induced M1 polarization of macrophages on tumor growth / 中国现代医生

Objective To study the effect of lipopolysaccharide(LPS)-induced M1 polarization of macrophages on tumor growth.Methods Female Balb/c mice were randomly divided into control group and experimental group.Renca cells were used to establish subcutaneous tumor model.NaCl(100μl/mice,once every two days)or LPS(100μg/mice,once every two days)was injected to the tumor side when the tumor grew to 50mm3.The M1 polarization level of tumor-associated macrophages was detected by flow cytometry.Mouse tumor cell lines(ML-1,MC38,Renca)were divided into three groups:blank group(complete medium with 50％DMEM basal medium),control group(complete medium with 50％medium supernatant of cultured macrophages)and experimental group(complete medium with 50％medium supernatant of LPS pretreated cultured macrophages).The proliferation of tumor cells was detected by cell counting kit-8(CCK-8).The cell cycle and apoptosis of tumor cells were detected by flow cytometry.Results The proportion of tumor-associated macrophages M1 increased after LPS treatment(P<0.001),thus enhancing its anti-tumor function.LPS-induced M1 polarization of macrophages can significantly inhibit the proliferation of tumor cells(Renca:P=0.023,ML-1:P=0.045).LPS-induced M1 polarization of macrophages blocked G0/G1 phase(MC38:P=0.011,ML-1:P=0.022)or S phase(Renca:P=0.022)of tumor cell cycle,and then cell division was inhibited.LPS-induced M1 polarization of macrophages significantly induced apoptosis of tumor cells(Renca:P=0.04,ML-1:P=0.007).Conclusion LPS can play an anti-tumor role by inducing M1 polarization of macrophages.

Research progress of Hedgehog signaling pathway inhibitors in anti-tumor field / 中国药房

Hedgehog （Hh） signaling pathway plays an important regulatory role in the process of cell proliferation， differentiation and tissue formation. Proper intensity and action time of Hh signal are crucial for the normal development of various tissues of the body， and its abnormal activation will lead to the occurrence and development of most malignant tumors， including breast cancer， liver cancer， pancreatic cancer， and lung cancer， which makes Hh signaling pathway an ideal target for anti-tumor drug research and development. At present， the main targets of Hh signaling pathway inhibitors include Hh ligand， receptor Smoothened （Smo） and transcription factor Gli. Among them， the compounds that depend on the Hh ligand pathway still remain at the stage of laboratory research because they cannot act on the non-classical Hh signaling pathway. The special structure of Smo protein enables it to combine with drugs efficiently and selectively， which is a powerful and effective drug target. Therefore， Smo selective inhibitors have been an active field of related research， and many Smo inhibitors have entered the clinical use or trial stage. Gli can regulate multiple carcinogenic genes， promote abnormal cell proliferation and lead to tumor， and can also cause feedback inhibition to Hh signaling pathway. Therefore， the development of drugs that can inhibit the activity of Gli has broad prospects. In the future， a combination of multiple pathway inhibitors can be designed to avoid drug resistance and other side effects.

Anti-tumor Mechanisms of Bruceine D： A Review / 中国实验方剂学杂志

Malignant tumors seriously threaten human life and health. Radiotherapy and chemotherapy are the conventional methods for the clinical treatment of advanced tumors. The prognosis and efficacy are still far from satisfactory due to the radiotherapy has serious adverse effects on the body and the chemotherapy often causes problems such as tumor resistance and cell proliferationinhibition. Therefore， the search for new， safe， and effective anti-tumor drugs and the elucidation of their molecular mechanisms are effective measures for clinical treatment of tumors and improvement of patients' quality of life. Active ingredients derived from Chinese herbal medicines and natural products have gradually become a hot spot in the research and development of anti-tumor drugs due to their multi-target and multi-channel anti-tumor pharmacological activity characteristics and their advantages such as less adverse reaction on the body. Bruceine D is a class of tetracyclic triterpenoids extracted from the fruit of the Chinese herbal medicine Bruceae Fructus， with anti-inflammatory， anti-malarial， anti-parasitic， and other pharmacological activities， and its anti-tumor activity is particularly significant. Pharmacological studies have found that bruceine D can regulate various cellular physiological activities such as proliferation， apoptosis， invasion， and migration of lung cancer， liver cancer， pancreatic cancer， intestinal cancer， and other cancer cells by targeting different signaling pathways. Bruceine D can be used in combination with other chemotherapeutic drugs to improve the sensitivity of tumor cells to chemotherapeutic drugs， thereby reducing the adverse effect of chemotherapy. Clinical application practice has shown that Bruceae Fructus oil emulsion injection containing bruceine D has significant advantages in the efficacy and safety of tumor treatment. Although there are many studies on the antitumor pharmacological activity of bruceine D and its clinical efficacy is significant， the specific antitumor molecular mechanism of bruceine D is still unclear， and there is a lack of systematic review on the existing antitumor mechanism of bruceine D. Therefore， based on the research on bruceine D in China and abroad in recent years， this paper reviewed the anti-tumor effect and related molecular mechanisms of bruceine D from six aspects， namely， tumor cell proliferation， apoptosis， metastasis and invasion， glucose metabolism process， autophagy， and chemotherapy sensitivity. This paper is expected to provide a pharmacological basis and scientific reference for the antitumor drug development and clinical application of bruceine D.

Anti-tumor Effect of Alkaloids of Chinese Medicine： A Review / 中国实验方剂学杂志

Malignant tumors， with the increasing crude morbidity and mortality year by year， have become the major diseases threatening human health. The conventional therapeutic drugs against tumors have serious adverse reactions， which can cause a heavy burden on patients. The active components of Chinese medicine can effectively inhibit tumor growth， improve the quality of life of patients， and have few toxic and side effects. Alkaloids of Chinese medicine are natural organic compounds widely existing in a variety of Chinese herbal medicines. In recent years， they have attracted more and more attention because of their anti-tumor effect. The anti-tumor mechanisms of alkaloids of Chinese medicine mainly include the induction of apoptosis， inhibition of tumor cell migration and invasion， suppression of proliferation， induction of autophagy of tumor cells， cell cycle arrest， inhibition of tumor angiogenesis， regulation of microRNA， and modulation of immunity. In addition， Chinese medicine alkaloids can also reverse tumor drug resistance and reduce the stemness of tumor stem cells. Alkaloids of Chinese medicine can regulate the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， c-Jun N-terminal kinase （JNK）， p38 mitogen-activated protein kinase （p38 MAPK）， mammalian target of rapamycin （mTOR）， Notch， Hedgehog， Wnt/β-catenin， and other signaling pathways to participate in the processes of tumor proliferation， invasion and metastasis， autophagy and apoptosis， and affect the occurrence and development of tumors in multiple links and ways. The derivatives and nano-preparations of alkaloids can improve the solubility， utilization， and anti-tumor activity of alkaloids， bringing a broader prospect for the clinical application of alkaloids. This review summarized the recent anti-tumor research on alkaloids， their representative derivatives， and nano-preparations to provide references for the in-depth research on the anti-tumor effect of alkaloids.

Natural Medicinal Components Mediating Pyroptosis by GSDMs in Anti-tumor Therapy： A Review / 中国实验方剂学杂志

Pyroptosis， an atypical new cell death mode other than apoptosis and necrosis， has been discovered in recent years. Pyroptosis depends on the cleavage of gasdermins （GSDMs） by Caspases. The activated GSDMs act on the plasma membrane to form a perforation， which results in cell lysis and triggers inflammation and immune response. Pyroptosis can be induced by four distinct signaling pathways， including canonical and non-canonical inflammasome pathways， apoptosis-associated Caspases-mediated pathway， and granzyme pathway. In these signaling pathways， GSDMs are the executors of pyroptosis. Pyroptosis is associated with the death of tumor cells and the inflammatory damage of normal tissues. Recent studies have demonstrated that moderate pyroptosis can lead to tumor cell death to exert an anti-tumor effect， and meanwhile stimulate the tumor immune microenvironment， while it can promote tumor development. Despite the good performance， drug-based anti-tumor therapies such as tumor immunotherapy， chemotherapy， and targeted therapy have some shortcomings such as drug resistance， recurrence， and damage to normal tissues. The latest research shows that a variety of natural compounds have anti-tumor effects in the auxiliary treatment of tumors by mediating the pyroptosis pathways in a multi-target and multi-pathway manner， which provide new ideas for the study of anti-tumor therapy. We reviewed the molecular mechanism of pyroptosis and the regulatory role of pyroptosis in tumors and tumor immune microenvironment， and summarized the recent research progress in the natural medicinal components regulating pyroptosis in anti-tumor therapy， with a view to providing ideas for the research on the anti-tumor therapy based on pyroptosis.

Effect and Mechanism of Cinobufotalin Against Gastrointestinal Malignant Tumors： A Review / 中国实验方剂学杂志

Digestive tract diseases， especially digestive tract tumors， including liver cancer， pancreatic cancer， and colorectal cancer， have high incidence in China. Digestive tract tumor is one of the top 10 cancers in terms of the number of new cases and deaths in the world， and the incidence and mortality of tumor diseases have been increasing year by year. Therefore， the prevention and treatment of tumors is particularly important. With the application and promotion of traditional Chinese medicine in the medical field and the rapid development of molecular biology and pharmacology， more and more potential active components of Chinese medicinal materials have been extracted and studied. These active components can inhibit tumor cells in a multi-target and multi-pathway manner. Cinobufotalin is an effective component extracted from the skin of Bufo bufo gargarizans. It has been prepared into a variety of agents with anti-tumor， immunomodulatory， cardiac boosting， pain-easing， anti-inflammatory， and swelling-relieving activities. In clinical practice， cinobufotalin is mainly used to assist the treatment of liver cancer， lung cancer， colorectal cancer， gastric cancer and other malignant tumors， which can reduce the adverse reactions of patients in the middle and late stages and improve the quality of life and five-year survival rate of patients. The available studies of molecular mechanism have demonstrated that cinobufotalin can play a therapeutic role by inducing cell apoptosis， regulating cell cycle， inhibiting cell proliferation and angiogenesis， modulating immune response， reversing multidrug resistance， enhancing radiochemotherapy sensitivity， inhibiting tumor inflammation， invasion， and metastasis， etc. This review focuses on the clinical application and mechanism of cinobufotalin against digestive tract tumors in recent years， aiming to provide a theoretical basis for the anti-tumor research of cinobufotalin， promote the application of cinobufotalin in tumor treatment， and facilitate the further research and development of this compound.

Anti-tumor Activity of Chinese Medicine Based on EGFR Signaling Pathway： A Review / 中国实验方剂学杂志

In China， malignant tumors have become the main cause of death. In the past half century， the incidence and mortality of malignant tumors have been on the rise， posing a threat to health of patients， and the burden of cancer has been increasing. At the moment， malignant tumors are mainly treated by surgery， radiotherapy， and cytotoxic drugs， which， however， have limitations and induce great adverse reactions. As biological technology and the research on tumor microenvironment， immunology， cell biology， and molecular biology advance， high-efficiency low-toxicity targeted therapy has attracted wide attention in the treatment of tumors. Epidermal growth factor receptor （EGFR） plays an important role in many cellular processes such as cell proliferation， survival， differentiation， migration， inflammation， and stromal homeostasis. EGFR promotes tumor growth， proliferation， and metastasis in a variety of ways. Chinese medicine has unique efficacy in the comprehensive treatment of malignant tumors. Through multiple components， multiple targets， and multiple pathways， it enhances the efficacy， reduces toxicity， prolongs life， and improves life quality in the treatment of tumors. Many Chinese medicines and their active components exert anti-tumor effect by inhibiting the EGFR signal transduction pathway. Through targeted inhibition of EGFR， Chinese medicine can promote the apoptosis and autophagy of tumor cells， suppress the proliferation and metastasis of tumor cells， and delay the progression of tumors. Thus， EGFR is a potential target for suppressing tumor. This paper summarizes the relationship between EGFR signal transduction pathway and tumor occurrence and development and analyzes the anti-tumor action mode and possible mechanisms of Chinese medicine and the active components by regulating EGFR signaling pathway， which is expected to provide a reference for clinical practice.
