In contrast, ADRB1, CHRNA3, HTR3A, GSTP1, and GABRG2 genes are candidate protective factors against depression.@*CONCLUSION@#This study identified the risk factors causally associated with depression and MDD, and estimated 10 drug targets with significant impact on MDD, providing essential information for formulating strategies to prevent and treat depression.

Liver Injury Caused by Psoraleae Fructus： A Review / 中国实验方剂学杂志

Psoraleae Fructus （PF） is a non-toxic Chinese herbal medicine， while the liver injury caused by PF has aroused wide concern in recent years. At present， animal experiments and in vitro studies have been carried out to explore the mechanism， targets， and toxic components of PF in inducing liver injury， which， however， have differences compared with the actual conditions in clinical practice， and there are still some potential hepatotoxic components and targets of PF that have not been discovered. With the continuous progress in systems biology， establishing the drug-induced liver injury model and the liver injury prediction model based on network toxicology can reduce the cost of animal experiments， improve the toxicity prediction efficiency， and provide new tools for predicting toxic components and targets. To systematically explain the characteristics of liver injury in the application of PF and explore the potential hepatotoxic components and targets of PF， we reviewed the related articles published by China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， and PubMed from 1962 to 2021 and analyzed the characteristics and influencing factors of liver injury caused by PF in the patients. Furthermore， we summarized the chemical components of PF and the components entering blood. By reviewing the mechanism， targets， and components of PF in inducing liver injury that were discovered by in vivo and in vitro experiments， we summarized the known compounds in PF that may cause liver injury. Finally， the current methods for building the prediction model of PF-induced liver injury were summarized， and the predicted toxic components and targets were introduced. The possible factors of PF in causing liver injury were explained from three aspects： clinical characteristics， preclinical studies， and computer-assisted network prediction， which provide a reference for predicting the risk of PF-induced liver injury.

Research and development practice of traditional Chinese medicine based on network target theory and technology / 中国中药杂志

Network targets theory and technology have transcended the limitations of the "single gene, single target" model, aiming to decipher the mechanisms of traditional Chinese medicine(TCM) based on biological network from the perspective of informatics and system. As the core of TCM network pharmacology, with the development of computer science and high-throughput experimental techniques, the network target theory and technology are beginning to exhibit a trend of organic integration with artificial intelligence technology and high-throughput multi-modal multi-omics experimental techniques. Taking the network target analysis of TCM like Yinqiao Qingre Tablets as a typical case, network target theory and technology have achieved the systematic construction, in-depth analysis, and high-throughput multi-modal multi-omics validation of multi-level biological networks spanning from traditional Chinese and Western phenotypes to tissues, cells, molecules, and traditional Chinese and Western medicines. This development helps to address critical issues in the analysis of mechanisms of TCM, including the discovery of key targets, identification of functional components, discovery of synergistic effects among compound ingredients, and elucidation of the regulatory mechanisms of formulae. It provides powerful theoretical and technological support for advancing clinical precision diagnosis and treatment, precise positioning of TCM, and precise research and development of TCM. Thus, a new paradigm of TCM research gradually emerges, combining big data and artificial intelligence(AI) with the integration of human experience and scientific evidence.

Research Progress of Antibody-drug Conjugates in Small-cell Lung Cancer / 肿瘤防治研究

Antibody-drug conjugates (ADCs) are novel drugs consisting of monoclonal antibodies targeting tumor-specific or tumor-associated antigens coupled with different numbers of payloads via linkers. ADCs have shown promising clinical benefits in the treatment of a variety of malignancies. Small-cell lung cancer (SCLC) is a hypo-differentiated neuroendocrine tumor with an extremely high degree of malignancy. Although SCLC is sensitive to radiotherapy and chemotherapy, it has a poor prognosis due to characteristics such as early susceptibility to metastasis and recurrence. Progress in the treatment of SCLC is very limited, and more durable and effective therapies should be developed to improve prognosis. However, the progress of SCLC-related therapeutic agents has been limited by the lack of specific molecular targets. This article reviews the basic principles and mechanisms of ADCs, highlights the research progress of relevant drugs against some targets in SCLC, and summarizes new targets that may be developed as targeted drugs.

ObjectiveTo reveal the targets and molecular mechanisms of the action of Qiangxin Decoction （强心汤） for the treatment of chronic heart failure based on the combination of network pharmacology and molecular docking. MethodsThe active ingredients of Qiangxin Decoction were retrieved from TCMSP database， and the targets of chronic heart failure were screened by searching GeneCards， OMIM， TTD， PharmGkb， and DrugBank databases， and the intersections were taken to obtain the intersecting targets of Qiangxin Decoction for the treatment of chronic heart failure. STRING platform was used to construct the protein-protein interaction network （PPI）， Cytoscape 3.8.0 software was used to calculate the network topology to screen the core targets， and R 4.2.3 was used to construct the “active ingredient-target” network by analyzing the GO enrichment analysis and KEGG pathway enrichment analysis. AutoDock 1.5.7 was used for molecular docking to predict the binding performance of active ingredients and core targets. ResultsSeventy-five intersecting targets were identified for the treatment of chronic heart failure with Qiangxin Decoction， among which the core targets were estrogen receptor 1 （ESR1， degree value=7）， nuclear receptor coactivator 1 （NCOA1， degree value=8）， glucocorticoid receptor （NR3C1， degree value=7）， and nuclear receptor coactivator 2 （NCOA2， degree value=7）. GO enrichment analysis showed that the top 3 items with the smallest P value in molecular function were G protein-coupled amine receptor activity， postsynaptic neurotransmitter receptor activity， and neurotransmitter receptor activity （P＜0.01）； the top 3 items with the smallest P value in biological process were adenylyl cyclase-activated adrenergic receptor signaling pathway， adrenergic receptor signaling pathway， and adenylyl cyclase-regulated G protein-coupled receptor signaling pathway （P＜0.01）； the top 3 items with the smallest P values in cellular composition were components of the postsynaptic membrane， synaptic membrane， and presynaptic membrane （P＜0.01）.

The molecular docking results showed that lignans and isoflavones had lower binding energies and more structural stability with the four core targets （ESR1， NCOA1， NR3C1， NCOA2）. ConclusionThe treatment of chronic heart failure by Qiangxin Decoction was associated with neuroactive ligand-receptor interactions， calcium signaling pathway， dopaminergic synapses， chemoattractant-receptor activation， cGMP-PKG signaling pathway， lipids and atherosclerosis， and cAMP signaling pathway， and lignans and isoflavones may be the core active compounds in its treatment of chronic heart failure.

Research progress of effect of gut microbiota on non-small cell lung cancer / 中国胸心血管外科临床杂志

@#The human gut microbiota regulates many host pathophysiological processes including metabolic, inflammatory, immune and cellular responses. In recent years, the incidence and mortality of lung cancer have increased rapidly, which is one of the biggest challenges in the field of cancer treatment today, especially in non-small cell lung cancer. Animal models and clinical studies have found that the gut microbiota of non-small cell lung cancer patients is significantly changed compared with the healthy people. The gut microbiota and metabolites can not only play a pro-cancer or tumor suppressor role by regulating immune, inflammatory responses and so on, but also be related with radiotherapy and chemotherapy of non-small cell lung cancer and the resistance of immunotherapy. Therefore, gut microbiota and related metabolites can be both potential markers for early diagnosis and prognosis in patients with non-small cell lung cancer and novel therapeutic targets for targeted drugs. This study will review the latest research progress of effect of gut microbiota on non-small cell lung cancer, and provide a new diagnosis and treatment ideas for non-small cell lung cancer.

The role of retinal signaling molecules in the occurrence and progression of myopia / 中华眼底病杂志

With the surged prevalence of myopia, the pathogenic mechanism underlying myopia has attracted attention. At present, it is generally believed in the flied that the reduced blood perfusion in the choroid is crucial for myopigenesis. Then, in the process of myopigenesis, how are the blurred visual signals transmitted to the choroidal blood vessels through the retina and retinal pigment epithelium, leading to the reduced choroidal blood perfusion. The cellular and molecular mechanisms underpinning this process remain elusive. In recent years, the theory of scleral hypoxia has attracted much attention. Popular signaling molecules in current research include dopamine, epidermal growth factor, retinoic acid, cholinergic molecules and adenosine, etc. These factors are likely to participate in signal transduction in retina and RPE, thus causing changes in choroidal blood flow and affecting the occurrence and development of myopia. Therefore, these signaling factors and their downstream pathways may provide new ideas for the prevention and control of myopia targets.

The Structure and Function of the Bunyavirus Nucleoprotein / 中国生物化学与分子生物学报

Bunyavirus is widely distributed, highly contagious, and has a high fatality rate. It is a negative- strand RNA virus that has a major impact on public health around the world. The development of vaccines and the search for drugs are the key to prevent bunyavirus infection. The nucleoprotein (NP) of viruses is necessary for the synthesis of viral RNA, which combines with viral RNA to form the nucleocapsid, participates in viral assembly and RNA transcription, and plays an important role in viral proliferation. In addition, NP also has B cell and T cell epitopes, which can induce cellular and humoral immunity, so NP is an ideal target for vaccine design and drug development. Given its abundance and specificity, NP is also commonly used in the detection of viral diseases. More and more bunyavirus NP structures and structures of NP-RNA complexes have been resolved. Researchers have discovered two important antiviral targets through these structures, the terminal arm and the RNA binding cleft. This paper reviews the function and three-dimensional structure of the bunyavirus NP and the research progress of NP as an antiviral target, in order to provide a theoretical basis for the prevention and treatment of the bunyavirus disease.

Biological Implication of Chimeric RNAs in Cancer / 中国生物化学与分子生物学报

Chimeric RNA is a fusion transcript composed of exons from two or more different genes and generated by chromosome rearrangement or RNA splicing. Chimeric RNAs have the potential to encode novel proteins or function as non-coding RNAs. Chimeric RNAs were ubiquitously expressed across different cancers and normal tissues. To date, mechanistic and functional studies of chimeric RNAs still remain unclear. Precise definition and terminology in the research field of chimeric RNA will be discussed in this review. The formation, classification and clinical significance of chimeric RNAs in cancer progression will be summarized. Previous studies showed that products of chimeric RNAs may play important roles in regulating cell proliferation, motility, invasion and apoptosis through encoded fusion proteins or long non-coding chimeric RNAs. In cancer, chimeric RNA and its encoded specific protein or non-coding RNA can regulate tumorigenesis by changing cell phenotypes or directly affecting gene expression or regulatory pathways, which have the potential to be important diagnostic biomarkers and therapeutic targets. In recent years, more and more cancer-specific chimeric RNAs have been discovered from multiple types of cancers and used as therapeutic targets due to their vital roles in disease prognosis. Therefore, this review will focus on the functions and applications of chimeric RNAs in different tumors, which can shed a light on cancer diagnosis and therapeutics from the new perspective.

Mechanism of neuronal death in ischemic stroke / 中国药理学通报

Stroke is the second leading cause of death in the world, of which about 60 % - 80 % are ischemic stroke. Ischemic stroke will inevitably cause the damage of neurons in the core area. With the increase of ischemic time, other neurons in the ischemic penumbra will also die due to the loss of " signal connection", and further lead to body dysfunction. In view of the complexity of neuronal death mechanism after ischemic stroke, understanding the action principle of death mechanism can better save ischemic penumbra neurons. This review mainly expounds several main mechanisms and potential therapeutic targets of neuronal death after ischemic stroke, so as to provide basis and help for the improvement of action mechanism research and drug development.

The traditional Chinese medicines treat chronic heart failure and their main bioactive constituents and mechanisms

Chronic heart failure (CHF) is a severe public health problem with increasing morbidity and mortality, any treatment targeting a single session is insufficient to tackle this. CHF is characterized by reduced cardiac output resulting from neurohumoral dysregulation and cardiac remodeling, which might be related to oxidative stress, inflammation, endoplasmic reticulum stress, apoptosis, autophagy, mitochondrial function, and angiogenesis. These molecular mechanisms interact with each other through crosstalk. Historically, Chinese medicinal herbs have been widely applied in the treatment of CHF, and therapeutic effects of Chinese medicinal herbs and their ingredients have been scientifically confirmed over the past decades. Traditional Chinese medicine (TCM) with multiple components can confront the different pathogenesis of CHF through multiple targets. This review analyzes commonly used TCM patent drugs and TCM decoctions that are applicable to different stages of CHF based on clinical trials. Diverse bioactive ingredients in Chinese medicinal herbs have been found to treat CHF via multiple molecular mechanisms. This review comprehensively covers the key works on the effects and underlying mechanisms of TCM, herbal ingredients and synergistic effects of constituent compatibility in treating CHF, providing additional ideas to address this threat.

Spatiotemporally resolved metabolomics and isotope tracing reveal CNS drug targets

Deconvolution of potential drug targets of the central nervous system (CNS) is particularly challenging because of the complicated structure and function of the brain. Here, a spatiotemporally resolved metabolomics and isotope tracing strategy was proposed and demonstrated to be powerful for deconvoluting and localizing potential targets of CNS drugs by using ambient mass spectrometry imaging. This strategy can map various substances including exogenous drugs, isotopically labeled metabolites, and various types of endogenous metabolites in the brain tissue sections to illustrate their microregional distribution pattern in the brain and locate drug action-related metabolic nodes and pathways. The strategy revealed that the sedative-hypnotic drug candidate YZG-331 was prominently distributed in the pineal gland and entered the thalamus and hypothalamus in relatively small amounts, and can increase glutamate decarboxylase activity to elevate γ-aminobutyric acid (GABA) levels in the hypothalamus, agonize organic cation transporter 3 to release extracellular histamine into peripheral circulation. These findings emphasize the promising capability of spatiotemporally resolved metabolomics and isotope tracing to help elucidate the multiple targets and the mechanisms of action of CNS drugs.
