ObjectiveTo predict the mechanism through which Shasheng Maidong Tang enhances the efficacy of chemotherapy for lung cancer via network pharmacology and validate the prediction results in animal experiments. MethodsThe potential mechanism through which Shasheng Maidong Tang enhances the efficacy of chemotherapy for lung cancer was predicted by network pharmacology, liquid chromatography-mass spectrometry (LC-MS), and molecular docking methods. C57/BL6 mice were assigned into normal, model, cisplatin, and Shasheng Maidong Tang+cisplatin groups. In addition to the normal group, the remaining groups were injected subcutaneously with 0.2 mL of 1×107 cells·mL-1 Lewis lung cancer cells to establish the Lewis lung cancer model. The daily gavage dose of Shasheng Maidong Tang was 3.58 g·kg-1, and the concentration of cisplatin intraperitoneally injected on every other day was 2 mg·kg-1. Drugs were administered for 14 d. The changes in the tumor volume and the rate of tumor suppression were monitored, and the tumor histopathological changes were observed by hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay was employed to measure the interleukin (IL)-6 and interferon (IFN)-γ levels in peripheral blood. Real-time PCR was performed to quantify the mRNA levels of Janus kinase 2 (JAK2), signal transducer and activator of transcription 1 (STAT1), and signal transducer and activator of transcription 3 (STAT3) in the tumor tissue of mice. Western blot was employed to determine the protein levels of JAK2, STAT3, B-cell lymphoma-2 (Bcl-2), cysteinyl aspartate-specific proteinase-3 (Caspase-3), and Pim-1 proto1 (PIM1) in the tumor tissue. Immunohistochemistry was employed to detect the expression of Bcl-2 and PIM1 in the tumor tissue. ResultsNetwork pharmacological predictions indicated that Shasheng Maidong Tang might enhance the efficacy of chemotherapy for lung cancer by regulating nitrogen metabolism, AGE-RAGE signaling pathway, cancer pathway, and JAK/STAT signaling pathway. The experimental results demonstrated that tumor volume in the cisplatin group and Shasheng Maidong Tang+cisplatin group was reduced compared with the model group, with statistically distinct differences observed on days 14, 17, 20 post modeling (P<0.05). Notably, the Shasheng Maidong Tang+cisplatin therapy further decreased tumor volume compared with the cisplatin group, showing marked reductions on days 17 and 20 (P<0.05), consistent with trends visualized in tumor volume comparison charts. The Shasheng Maidong Tang+cisplatin group exhibited higher tumor inhibition rate than the cisplatin group (P<0.05). Histopathological analysis via HE staining revealed that the tumors in the model group displayed frequent nuclear mitosis, densely arranged cells, hyperchromatic nuclei, and no necrosis. Cisplatin treatment induced partial necrosis and vacuolization, while the Shasheng Maidong Tang+cisplatin group exhibited extensive necrotic regions, maximal vacuolization, disarranged tumor cells, and minimal mitotic activity. Compared with the model group, the cisplatin group and the Shasheng Maidong Tang+cisplatin group showed elevated level of IFN-γ (P<0.01) and declined level of IL-6 (P<0.01) in the peripheral blood. Compared with the cisplatin group, the Shasheng Maidong Tang+cisplatin group presented elevated level of IFN-γ (P<0.01) and lowered level of IL-6 (P<0.01) in the peripheral blood. Compared with the model group, the cisplatin group and the Shasheng Maidong Tang+cisplatin groups showed down-regulated mRNA levels of JAK2 and STAT3 (P<0.01) and up-regulated mRNA level STAT1 (P<0.01). Compared with the cisplatin group, the Shasheng Maidong Tang+cisplatin group presented down-regulated mRNA levels of JAK2 and STAT3 (P<0.01) and up-regulated mRNA level of STAT1 (P<0.01). Compared with the model group, the cisplatin group and the Shasheng Maidong Tang+cisplatin group showed down-regulated protein levels of JAK2 (P<0.01), Bcl-2 (P<0.01), PIM1 (P<0.01), and STAT3 (P<0.05), and up-regulated protein level of Caspase-3 (P<0.01). Compared with the cisplatin group, Shasheng Maidong Tang+cisplatin group presented down-regulated protein levels of JAK2 (P<0.01), Bcl-2 (P<0.01), PIM1 (P<0.01), STAT3 (P<0.05), and up-regulated protein level of Caspase-3 (P<0.01). The Bcl-2 and PIM1 expression results obtained by immunohistochemistry were consistent with those of Western blot. ConclusionShasheng Maidong Tang may enhance the efficacy of chemotherapy in the mouse model of Lewis lung cancer by regulating the JAK2/STAT3 signaling pathway.

Chronic heart failure (CHF) is a group of complex clinical syndromes caused by abnormal changes in the structure and/or function of the heart due to various reasons, resulting in disorders of ventricular contraction and/or diastole. CHF is a condition where primary diseases such as coronary heart disease, hypertension and pulmonary heart disease recur frequently and persist for a long time, presenting blood stasis in meridians and collaterals, stagnation of water and dampness, and accumulation of Qi in collaterals. Its pathogenesis is complex and may involve myocardial energy metabolism disorders, oxidative stress responses, myocardial cell apoptosis, autophagy, inflammatory responses, etc. According to the theory of restraining hyperactivity to acquire harmony, we believe that under normal circumstances, the adenosine monophosphate-activated protein kinase (AMPK) signaling pathway functions normally, maintaining human physiological activities and energy metabolism. Under pathological conditions, the AMPK signaling pathway is abnormal, causing energy metabolism disorders, inflammatory responses, and myocardial fibrosis. Traditional Chinese medicine (TCM) can regulate the AMPK signaling pathway through multiple mechanisms, targets, and effects, effectively curbing the occurrence and development of CHF. It has gradually become a research hotspot in the prevention and treatment of this disease. Guided by the theory of TCM, our research group, through literature review, summarized the relationship between the AMPK pathway and CHF and reviewed the research progress in the prevention and control of CHF with TCM active ingredients, TCM compound prescriptions, and Chinese patent medicines via regulating the AMPK pathway. The review aims to clarify the mechanism and targets of TCM in the treatment of CHF by regulating the AMPK pathway and guide the clinical treatment and drug development for CHF.

Chronic heart failure (CHF) refers to a clinical syndrome in which the function or structure of the heart is changed due to damage to the original myocardium, resulting in reduced pumping and/or filling functions of the heart. In recent years, the mechanisms, pathways, and targets of traditional Chinese medicine (TCM) in the treatment of CHF have been continuously confirmed, and the application of TCM theories in guiding the syndrome differentiation and precise treatment of CHF is currently a research hotspot. On the basis of the syndrome differentiation and treatment in TCM, Professor LI Candong innovatively proposed the thinking of five differentiation: Disease differentiation, syndrome differentiation, pathogenesis differentiation, symptom differentiation, and individual differentiation. This article explores the clinical diagnosis and treatment of CHF from this thinking, emphasizing comprehensive syndrome differentiation, objective analysis, dynamic assessment, and individualized treatment. In terms of diagnosis, the first is to identify the disease name, cause, location, severity, and type of CHF, determine the type and its evolution, and clarify the process of transmission and transformation between deficiency and excess. Secondly, it is necessary to distinguish the authenticity, severity, primary and secondary, urgency and complexity of CHF syndromes, providing scientific guidance for syndrome differentiation and treatment. Thirdly, according to the symptoms and the principles of deficiency and excess, the physician should identify the core pathogenesis of CHF from the perspectives of Qi, blood, Yin, Yang, deficiency, stasis, phlegm, water, and toxins. Fourthly, from the macro, meso and micro levels, the physician should carefully distinguish the presence or absence, severity, authenticity, and completeness of the symptoms to guide the diagnosis and treatment process of CHF. Finally, personalized medication for CHF should be promoted based on the patient's gender, age, constitution, and living habits. In terms of treatment, based on the thinking of five differentiation, we propose that the treatment of CHF should integrate the disease and syndrome, clarify the pathogenesis, and apply precise treatment. The treatment should be people-oriented, staged, and typed, and the medication should be adjusted according to symptoms. This diagnostic and therapeutic approach is based on the holistic concept and syndrome differentiation and treatment, and combines the three causes for appropriate treatment, providing new ideas and insights for the diagnosis and treatment of CHF.

Alzheimer’s disease (AD) is a chronic neurodegenerative disorder that severely affects the health of the elderly, marked by its incurability, high prevalence, and extended latency period. The current approach to AD prevention and treatment emphasizes early detection and intervention, particularly during the pre-AD stage of mild cognitive impairment (MCI), which provides an optimal “window of opportunity” for intervention. Clinical detection methods for MCI, such as cerebrospinal fluid monitoring, genetic testing, and imaging diagnostics, are invasive and costly, limiting their broad clinical application. Speech, as a vital cognitive output, offers a new perspective and tool for computer-assisted analysis and screening of cognitive decline. This is because elderly individuals with cognitive decline exhibit distinct characteristics in semantic and audio information, such as reduced lexical richness, decreased speech coherence and conciseness, and declines in speech rate, voice rhythm, and hesitation rates. The objective presence of these semantic and audio characteristics lays the groundwork for computer-based screening of cognitive decline. Speech information is primarily sourced from databases or collected through tasks involving spontaneous speech, semantic fluency, and reading, followed by analysis using computer models. Spontaneous language tasks include dialogues/interviews, event descriptions, narrative recall, and picture descriptions. Semantic fluency tasks assess controlled retrieval of vocabulary items, requiring participants to extract information at the word level during lexical search. Reading tasks involve participants reading a passage aloud. Summarizing past research, the speech characteristics of the elderly can be divided into two major categories: semantic information and audio information. Semantic information focuses on the meaning of speech across different tasks, highlighting differences in vocabulary and text content in cognitive impairment. Overall, discourse pragmatic disorders in AD can be studied along three dimensions: cohesion, coherence, and conciseness. Cohesion mainly examines the use of vocabulary by participants, with a reduction in the use of nouns, pronouns, verbs, and adjectives in AD patients. Coherence assesses the ability of participants to maintain topics, with a decrease in the number of subordinate clauses in AD patients. Conciseness evaluates the information density of participants, with AD patients producing shorter texts with less information compared to normal elderly individuals. Audio information focuses on acoustic features that are difficult for the human ear to detect. There is a significant degradation in temporal parameters in the later stages of cognitive impairment; AD patients require more time to read the same paragraph, have longer vocalization times, and produce more pauses or silent parts in their spontaneous speech signals compared to normal individuals. Researchers have extracted audio and speech features, developing independent systems for each set of features, achieving an accuracy rate of 82% for both, which increases to 86% when both types of features are combined, demonstrating the advantage of integrating audio and speech information. Currently, deep learning and machine learning are the main methods used for information analysis. The overall diagnostic accuracy rate for AD exceeds 80%, and the diagnostic accuracy rate for MCI also exceeds 80%, indicating significant potential. Deep learning techniques require substantial data support, necessitating future expansion of database scale and continuous algorithm upgrades to transition from laboratory research to practical product implementation.

With the continuous development of society, a large number of new chemicals are continuously emerging, which presents a challenge to current risk assessment and safety management of chemicals. Traditional toxicology research methods have certain limitations in quickly, efficiently, and accurately assessing the toxicity of many chemicals, and cannot meet the actual needs. In response to this challenge, computational toxicology that use mathematical and computer models to achieve the prediction of chemical toxicity has emerged. In the meantime, as researchers increasingly pay attention to understanding the interaction mechanisms between exogenous chemical substances and the body from the system level, and multiomics technologies develop rapidly such as genomics, transcriptomics, proteomics, and metabolomics, huge amounts of data have been generated, providing rich information resources for studying the interactions between chemical substances and biological molecules. System toxicology and network toxicology have also developed accordingly. Of these, network toxicology can integrate these multiomics data to construct biomolecular networks, and then quickly predict the key toxicological targets and pathways of chemicals at the molecular level. This paper outlined the concept and development of network toxicology, summarized the main methods and supporting tools of network toxicology research, expounded the application status of network toxicology in studying potential toxicity of exogenous chemicals such as agricultural chemicals, environmental pollutants, industrial chemicals, and foodborne chemicals, and analyzed the development prospects and limitations of network toxicology research. This paper aimed to provide a reference for the application of network toxicology in other fields.

By consulting relevant literature of ancient herbal books and processing specifications, this paper made a systematic research and analysis of Ostreae Concha, including the name, producing area, harvesting, quality, historical evolution of processing, relevant processing specifications, modern processing technology, and changes in chemical composition and pharmacological effects before and after processing, in order to provide documentary evidence for the research on processing technology and the establishment of quality standards. According to the textual research, it is known that Ostreae Concha has a long history of being used in medicine, and there have been many aliases and local names in each historical period. Shennong's Classic of the Materia Medica(Shennong Bencaojing) began to use Muli as the correct name, which has continued to use to today, and there were also aliases such as Muge, Zuogu Muli and Haoke. Ostreae Concha has a wide range of localities and irregular harvesting periods. The ancients believed that its left shell was of superior quality, but this has not been seen in modern. And there were many kinds of processing methods of Ostreae Concha, such as grinding, roasting, calcining, frying, simmering, quenching and so on, and the calcining was still in use. The different editions of Chinese Pharmacopoeia from 1963 to 2020 contain only calcined Ostreae Concha, and the local processing specifications mainly include three kinds of processed products(calcined products, salt-soaked products and vinegar-soaked products). Modern processing research mainly focuses on process optimization, changes in chemical composition and pharmacological effects, and the research methods are relatively single. Overall, there are currently issues such as inconsistent processing standards, unclear process parameters and imperfect quality standards, which are not conducive to the quality control and standardized clinical use of Ostreae Concha. Therefore, it is necessary to further investigate the pharmacological substance basis of Ostreae Concha and its processed products in order to elucidate the processing mechanism, standardize the processing technology and improve the quality standard.

ObjectiveTo explore the differences in the accumulation of secondary metabolites of Dendrobium nobile cultivated on epiphytic stones and trees, so as to elucidate the scientific connotation of "only those that grow on stones has superior quality", and provide a direction for the cultivation and quality evaluation of D. nobile. MethodsUltra-performance liquid chromatography-triple quadrupole/linear ion trap mass spectrometry(UPLC-QTRAP-MS/MS)-based widely targeted metabolomics was used to detect the metabolites of D. nobile cultivated on epiphytic stones and trees. And the combination of principal component analysis(PCA), hierarchical cluster analysis(HCA), and orthogonal partial least squares-discriminant analysis(OPLS-DA) was performed for multivariate statistical analysis of metabolites. Differential metabolites were screened by variable importance in the projection(VIP) value≥1 and log2fold change(FC)≥1 or ≤-1, and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis was conducted. ResultsA total of 1 267 metabolites were identified in the stems of D. nobile from the two cultivation modes, dominated by flavonoids(292), phenolic acids(284), and alkaloids(189). Through OPLS-DA screening, 473 differential metabolites were obtained. Compared to epiphytic tree-cultivated D. nobile, epiphytic stone-cultivated D. nobile exhibited upregulation of flavonoids, phenolic acids, alkaloids, lignans and coumarins, while quinones and terpenoids were down-regulated. The differential metabolites mainly included flavonoid glycosides and alkaloids, and these differential metabolites significantly contributed to characterizing the two cultivation patterns. KEGG enrichment analysis revealed significant enrichment in pathways of flavone and flavonol biosynthesis, flavonoid biosynthesis, tyrosine metabolism, and phenylalanine metabolism in epiphytic stone-cultivated D. nobile. ConclusionEpiphytic stone cultivation is beneficial for the accumulation of phenolic acids, flavonoids, and alkaloids in D. nobile, indicating that the "only those that grow on stones has superior quality" documented in the materia medica has certain scientific basis, and the findings also provide a reference for quality evaluation and discrimination research between epiphytic stone and tree cultivated D. nobile.

ObjectiveTo unveil the mechanism of Jianpi Huogu prescription (JPHGP) in ameliorating the dyslipidemia of steroid-induced osteonecrosis of the femur head (SONFH) by oxylipidomics combined with transcriptomics. MethodsSixty SD rats were assigned into normal, model, low-, medium-, and high-dose (2.5, 5, 10 g·kg-1, respectively) JPHGP, and Jiangushengwan (1.53 g·kg-1) groups. Lipopolysaccharide was injected into the tail vein at a dose of 20 μg·kg-1 on days 1 and 2, and methylprednisolone sodium succinate was injected at a dose of 40 mg·kg-1 into the buttock muscle on days 3 to 5. The normal group received an equal volume of normal saline. Drug administration by gavage began 4 weeks after the last injection, and samples were taken after administration for 8 weeks. Hematoxylin-eosin staining was conducted to reveal the histopathological changes of the femoral head, and the number of adipocytes, the rate of empty bone lacunae, and the trabecular area were calculated. Micro-computed tomography was used for revealing the histological and histomorphometrical changes of the femoral head. Enzyme-linked immunosorbent assay was employed to measure the serum levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB). At the same time, the femoral head was collected for oxylipidomic and transcriptomic detection. The differential metabolites and differential genes were enriched and analyzed, and the target genes regulating lipid metabolism were predicted. The predicted target proteins were further verified by molecular docking, immunohistochemistry, and Western blot. ResultsCompared with the normal group, the model group showcased thinning of the femoral head, trabecular fracture, karyopyknosis, subchondral cystic degeneration, increases in the number of adipocytes and the rate of empty bone lacunae (P<0.01), a reduction in the trabecular area (P<0.01), decreases in BMD, Tb.Th, Tb.N, and BV/TV, and increases in Tb.Sp and BS/BV (P<0.01). Compared with the model group, the JPHGP groups showed no obvious thinning of the femoral head or subchondroidal cystic degeneration. The high- and medium-dose JPHGP groups presented declines in the number of adipocytes and the rate of empty bone lacunae, an increase in the trabecular area (P<0.05, P<0.01), rises in BMD, Tb.Th, Tb.N, and BV/TV, and decreases in Tb.Sp and BS/BV (P<0.05, P<0.01). Compared with the normal group, the model group showcased raised serum levels of TG, TC, LDL, and ApoB and lowered serum levels of HDL and ApoA1 (P<0.01). Compared with the model group, the JPHGP groups had lowered serum levels of TG, TC, LDL, and ApoB (P<0.05, P<0.01) and a risen serum level of ApoA1 (P<0.05, P<0.01). Moreover, the serum level of HDL in the high-dose JPHGP group increased (P<0.01). A total of 19 different metabolites of disease set and drug set were screened out by oxylipidomics of the femoral head, and 119 core genes with restored expression were detected by transcriptomics. The enriched pathways were mainly concentrated in inflammation, lipids, apoptosis, and osteoclast differentiation. Molecular docking, immunohistochemistry, and Western blot results showed that compared with the normal group, the model group displayed increased content of 5-lipoxygenase (5-LO) and peroxisome proliferator-activated receptor γ (PPARγ) in the femoral head (P<0.01). Compared with the model group, medium- and high-dose JPHGP reduced the content of 5-LO and PPARγ (P<0.05, P<0.01). ConclusionJPHGP can restore the levels of oxidized lipid metabolites by regulating the 5-LO-PPARγ axis to treat SONFH in rats. Relevant studies provide experimental evidence for the efficacy mechanism of JPHGP in the treatment of SONFH.
