RESUMO
This study aimed to systematically evaluate the effectiveness and safety of Tanreqing Injection in the treatment of severe pneumonia in the elderly. Eighteen randomized controlled trials(RCTs) involving 1 457 elderly patients with severe pneumonia were included in the study after conducting searches in both Chinese and English databases as well as clinical trial registration platforms. The quality of the included studies was assessed using the Cochrane risk of bias assessment tool. Meta-analysis were conducted using RevMan 5.4 and Stata 17 software, and trial sequential analysis(TSA) was performed using TSA 0.9.5.10 beta software. Meta-analysis results showed that compared with conventional western medicine treatment, Tanreqing Injection + conventional western medical significantly improved the clinical effectiveness in elderly patients with severe pneumonia(RR=1.26, 95%CI[1.20, 1.32], P<0.000 01), arterial oxygen partial pressure(SMD=6.23, 95%CI[3.29, 9.18], P<0.000 1), oxygenation index(SMD=11.72, 95%CI[4.41, 19.04], P=0.002), reduce procalcitonin(SMD=-6.16, 95%CI[-8.10,-4.21], P<0.000 01), C-reactive protein(SMD=-8.50, 95%CI[-11.05,-5.96], P<0.000 01), white blood cell count(SMD=-4.56, 95%CI[-5.73,-3.39], P<0.000 01), and shortened the duration of fever(SMD=-3.12, 95%CI[-4.61,-1.63], P<0.000 1), cough(SMD=-4.84, 95%CI[-6.90,-2.79], P<0.000 01), lung rales(SMD=-0.99, 95%CI[-1.54,-0.44], P=0.000 4), and mechanical ventilation time(SMD=-3.26, 95%CI[-5.03,-1.50], P=0.000 3), increase CD4~+ T-cell levels(SMD=6.73, 95%CI[5.23, 8.23], P<0.000 01) and CD8~+ T-cell levels(SMD=7.47, 95% CI[5.32, 9.61], P<0.000 01) with no significant adverse reactions. TSA confirmed the stability and reliability of the results related to clinical effectiveness. This study suggests that Tanreqing Injection, as a Chinese medicinal preparation, has a significant therapeutic effect and good safety profile in the treatment of severe pneumonia in elderly patients. Due to the limited quality of the included studies, high-quality RCT is still needed to provide evidence support for the above conclusions.

BACKGROUND: Stable angina pectoris (SAP) is a clinical condition characterized by reversible and temporary myocardial ischemia and hypoxia. A majority of SAP patients also experience depressive disorders, which adversely affect their disease prognosis and overall quality of life. However, the clinical utility of existing antidepressants is constrained by their side effects. Ginkgo biloba dropping pill (GBDP), a Chinese patented medication, has demonstrated efficacy in the treatment of both coronary heart disease and mental disorders. This prospective, randomized, double-blind, multicenter clinical trial aimed to assess the effectiveness and safety of GBDP as an adjuvant therapy for SAP complicated by depression. METHODS: Participants were randomly assigned in a 1:1 ratio to receive either GBDP or a placebo (5 pills, three times a day) in addition to standard therapy for a duration of 12 weeks. The Seattle Angina Questionnaire (SAQ) was administered every 4 weeks during the treatment, and angina event frequency was assessed weekly. The 36-item Short-Form (SF-36) and Hamilton Depression Scale (HAMD) scores were measured both before and after the treatment. RESULTS: Out of the 72 patients, 68 (n = 34 per group) completed the entire study. At the first visit (4 weeks ± 3 days), the SAQ-Angina Stability score in the GBDP group was significantly higher than that in the placebo group (p < 0.05). While the average weekly frequency of angina episodes in the placebo group notably increased after 12 weeks of treatment (p < 0.05), it displayed an improving trend in the GBDP group (p > 0.05). By the endpoint, each subcategory score of SF-36 in the GBDP group exhibited significant improvement compared to baseline (p < 0.05). The comparison of score improvement between the two groups revealed that the SF-PCS score of the GBDP group was higher than that of the placebo group (p < 0.05). HAMD scores in both groups significantly increased after treatment (p < 0.05). No discernible difference in the incidence of adverse reactions was observed between the two groups (p > 0.05). CONCLUSION: In patients with SAP complicated by depression, GBDP, when combined with standard treatment, rapidly and safely alleviates angina pectoris symptoms. It demonstrates therapeutic potential in enhancing the quality of life and alleviating depressive symptoms.

Traditional Chinese medicine(TCM) preparations in medical institutions, as a unique and important form of preparations in China, have a long history of human use and serve as a bridge between clinical experience prescriptions and new Chinese medicine preparations. The state encourages medical institutions to transform their preparations into new traditional Chinese medicines, emphasizing their role as "incubators". Since the proposal of the traditional Chinese medicine registration and evaluation evidence system with the integration of TCM theory, human use experience(HUE), and clinical experience, the idea of transforming preparations used in medical institutions into new drugs based on HUE has been increasingly valued by drug research and development organizations. In the transformation process, pharmaceutical changes should be concerned from multiple aspects. This paper discusses the pharmaceutical changes and countermeasures based on the transformation of traditional Chinese medicine preparations in medical institutions into new drugs based on HUE from the aspects of excipients, dosage forms, production technology, production scale, packaging materials and containers, production sites, and registration standards. It is emphasized that scientific decisions should be made according to the characteristics and clinical needs of drugs to ensure the stability of drug quality. The impacts of pharmaceutical changes on drug quality should be objectively assessed based on appropriate evaluation indexes and detection methods. The layout should be carried out in advance, and the key pharmaceutical information of the preparations should be kept stable, so as to underpin the transformation of traditional Chinese medicine preparations in medical institutions into new drugs based on HUE.

The human use experience of traditional Chinese medicine(TCM) is of great significance for the development of new traditional Chinese medicine. In 2023, the National Medical Products Administration(NMPA) issued the Special Regulations on Registration Management of Traditional Chinese Medicine, which explicitly encouraged the conduct of high-quality human use experience research on TCM clinical practice to obtain sufficient evidence for registration support. It also required that human use experience research should comply with relevant requirements and undergo registration verification. The quality of human use experience research on TCM directly determines the reliability of the evidence. This article discussed the quality requirements for human use experience research on TCM from the perspectives of basic requirements, organizational management, key pharmaceutical information, scientific research, risk management, ethical compliance, and study implementation and proposed differential treatment in quality requirements and registration verification focus based on different research purposes, stages, and types of studies. While ensuring the authenticity of data, retrospective studies should pay particular attention to the integrity of the data, and prospective studies should focus on the normativity of the data, which may affect the research conclusions. Human use experience research, as part of drug registration materials, falls within the scope of relevant regulatory oversight. Researchers should have a strong awareness of regulations to avoid serious quality issues. The standardized conduct of human use experience research on TCM requires joint efforts from regulatory authorities, applicants, research institutions, and researchers to establish a research quality management system based on the clinical characteristics of TCM.

Evidence-based medicine plays an important role in promoting the scientific nature of clinical decision-making. Howe-ver, there is a problem where evidence derived from clinical research may not necessarily be applicable to individual patients. Evidence-based medicine has been introduced into the field of traditional Chinese medicine(TCM) for over 20 years, and although certain achievements have been made, the overall level of clinical research evidence based on the principles of evidence-based medicine in TCM is not high. The acceptance of TCM diagnosis and treatment guidelines developed based on evidence-based medicine methods is generally low. As revealed by the analysis of the problems in the application of evidence-based medicine in the field of TCM, it is found that there is a structural contradiction between clinical randomized controlled trial(RCT) of TCM and the characteristics of TCM clinical practice. They cannot comprehensively, objectively, and truthfully reflect the clinical efficacy and safety of TCM. Conducting clinical RCTs of TCM in pursuit of "evidence" actually means giving up the advantages of TCM in clinical treatment based on syndrome differentiation, prescription changes along with syndromes, and treatment in accordance with three categories of disease cause, which leads to sacrificing some clinical effectiveness of TCM. Based on the concept of evidence-based medicine, this article proposed the construction of "clinical syndrome-based medicine" based on the optimal clinical experience, which was suitable for the characteristics of TCM clinical practice. The key to clinical syndrome-based medicine is the optimal clinical experience, and the core elements of the optimal clinical experience are regularity and reproducibility. Real-world research methods are recommended as a reference for obtaining the optimal clinical experience. Clinical syndrome-based medicine, combining the characteristics of TCM clinical practice and incorporating the concept of evidence-based medicine, is the product of integrating TCM into evidence-based medicine. It is dedicated to improving the clinical efficacy of TCM along with evidence-based medicine.

BACKGROUND: Muscle wasting increases morbidity and mortality and is related to chronic kidney disease (CKD) and dialysis. It is still unclear whether ferroptosis occurs during this progression and whether it is a potential intervention target for the treatment of CKD-related muscle injury. PURPOSE: The objective is to identify potential compounds for treating ferroptosis and muscle wasting and explore the potential mechanisms in vivo/in vitro. METHODS: Initially, we explored whether ferroptosis is present in the skeletal muscle of 5/6 nephrectomized (NPM) mice via RNA-Seq analysis, TUNEL staining, Oil red O staining, MDA/GSH/GSSG level detection and real-time quantitative PCR (qPCR). Subsequently, utilizing our established molecular phenotyping strategy, we screened potential traditional Chinese herb-derived compounds for alleviation of muscle wasting and ferroptosis. HE staining, Oil red O staining, TUNEL staining, immunofluorescence staining, MDA/GSH/GSSG level detection, Fe level detection, western blotting and qPCR were applied to assess the effects of the identified compound on muscle wasting and ferroptosis and explore the potential mechanism. Furthermore, RNA-Seq analysis, ChIP-Seq analysis and further experiments in vitro were performed to determine the role of Hedgehog signaling in the effect of Lobetyolin (LBT) on ferroptosis. RESULTS: In NPM mice, skeletal muscle dysfunction, lipogenesis, reduced GSH/GSSG ratio, decreased GSH content, increased MDA production and and higher levels of ferroptosis markers were observed. LBT treatment (30 mg/kg or 50 mg/kg) significantly alleviates skeletal muscle injury by inhibiting ferroptosis. Additionally, in an in vitro investigation, C2C12 cells exposed to Indolyl sulfate (IS) induced ferroptosis and LBT treatment (20 µM and 50 µM) protected C2C12 from such injury, consistent with the results from the in vivo analysis. Furthermore, it was found LBT increased the levels of protein involving Hedgehog signaling pathway (SMO and GLI1), and rescue analysis revealed that this pathway played a crucial role in the regulation of ferroptosis. Further experiments demonstrated that LBT upregulated a series of suppressors of ferroptosis by activating Gli1 transcription. CONCLUSION: LBT alleviates CKD-induced muscle injury by inhibiting ferroptosis through activation of the Hedgehog signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Acacetin is widely distributed in traditional Chinese medicine and traditional herbs, with strong biological activity. Perhaps there are many potential effects that have not been explored. In the field of drug discovery, Mainstream methods focus on chemical structure. Traditional medicine cannot adapt to the mainstream prediction methods due to its complex composition. AIM OF THE STUDY: Our aim is that provide a prediction method more suitable for traditional medicine by graph representation learning and transcriptome data. And use this method to predict acacetin. MATERIALS AND METHODS: Our method mainly consists of two parts. The first part is to use the method of graph representation learning to vectorize drugs as a database. The original data of this part comes from transcriptome data on Gene Expression Omnibus. The method of graph representation learning is an unsupervised learning. If there is no prior knowledge as the label data, the training effect cannot be analyzed. Therefore, we define a standard score to evaluate our results through the idea of Jaccard index. The second part is to put the target drug into our database. The potential similarity between drugs was evaluated by the Euclidean distance between vectors, and the potential efficacy of the target drug is predicted by combining the chemical-disease relationship data in the Comparative Toxicogenomics Database. The target drug in this paper uses acacetin. We compared the predicted results with existing reports, and we also experimentally verified the efficacy of improving insulin resistance in the predicted results. RESULTS: The prediction results are relatively consistent with the existing reports, which demonstrated that our method has a certain degree of predictive performance. And for the efficacy of improving insulin resistance in the predicted result, we verified it through experiments. CONCLUSIONS: We propose a method to predict the potential efficacy of drugs based on transcriptome data, using Graph representation learning, which is very suitable for traditional medicine. Through this method, we predicted the efficacy of acacetin, and the results are relatively consistent with the current reports. This provides a new idea for unsupervised learning to apply medical information.

RESUMO
BACKGROUND: Cardiovascular diseases are the major cause of mortality in patients with advanced chronic kidney diseases. The predominant abnormality observed among this population is cardiac dysfunction secondary to myocardial remodelings, such as hypertrophy and fibrosis, emphasizing the need to develop potent therapies that maintain cardiac function in patients with end-stage renal disease. AIMS: To identify potential compounds and their targets as treatments for cardiorenal syndrome type 4 (CRS) using molecular phenotyping and in vivo/in vitro experiments. METHODS: Gene expression was assessed using bioinformatics and verified in animal experiments using 5/6 nephrectomized mice (NPM). Based on this information, a molecular phenotyping strategy was pursued to screen potential compounds. Picrosirius red staining, wheat germ agglutinin staining, Echocardiography, immunofluorescence staining, and real-time quantitative PCR (qPCR) were utilized to evaluate the effects of compounds on CRS in vivo. Furthermore, qPCR, immunofluorescence staining and flow cytometry were applied to assess the effects of these compounds on macrophages/cardiac fibroblasts/cardiomyocytes. RNA-Seq analysis was performed to locate the targets of the selected compounds. Western blotting was performed to validate the targets and mechanisms. The reversibility of these effects was tested by overexpressing Osteopontin (OPN). RESULTS: OPN expression increased more remarkably in individuals with uremia-induced cardiac dysfunction than in other cardiomyopathies. Lobetyolin (LBT) was identified in the compound screen, and it improved cardiac dysfunction and suppressed remodeling in NPM mice. Additionally, OPN modulated the effect of LBT on cardiac dysfunction in vivo and in vitro. Further experiments revealed that LBT suppressed OPN expression via the phosphorylation of c-Jun N-terminal protein kinase (JNK) signaling pathway. CONCLUSIONS: LBT improved CRS by inhibiting OPN expression through the JNK pathway. This study is the first to describe a cardioprotective effect of LBT and provides new insights into CRS drug discovery.

Human use experience(HUE) is important for the research and development of Chinese medicine. For the sake of more reliable data, the Professional Committee for Clinical Evaluation of Chinese Medicine of Chinese Pharmaceutical Association drafted the Expert Consensus on Human Use Experience Research of Traditional Chinese Medicine. It highlights that the research on HUE should have clear purposes, describe the theoretical basis of traditional Chinese medicine(TCM) for the clinical indications and prescriptions and the clinical value of prescriptions, especially the advantages or characteristics in clinical orientation and target population, evaluate the dosages and number of medicinals of prescriptions, verify the accordance with the preparation process of new Chinese medicine, analyze feasibility of the process for large-scale production and the rationality of the dosage form, and assess the medicinal material resources. Moreover, such research should have reasonable protocol and the collection of clinical data on HUE must comply with medical ethics and avoid conflicts of interest. The collection method should be selected depending on the characteristics of clinical data. Quality control measures should be formulated to ensure the authenticity, accuracy, completeness, reliability, and traceability of clinical data. The definitions on the clinical data should be uniform and clear, and methods should be adopted to avoid bias. The data can be statistically analyzed after the processing. Through the study of HUE, the clinical orientation, target population, commonly used dosage, course of treatment, preliminary efficacy and safety of Chinese medicine prescriptions will be clarified. On this basis, the data on the HUE should be discussed and conclusions will be drawn. Finally, a standardized report will be formed.

ETHNOPHARMACOLOGICAL RELEVANCE: Cardiorenal syndrome type 4 (CRS type 4), with high rates of morbidity and mortality, has become a social and economic problem worldwide over the last few decades. Zhen-Wu decoction, a traditional medicine used in East Asia, has been widely used in the treatment of cardiovascular disease and kidney disease, and has shown potential therapeutic effects for the clinical treatment of CRS type 4. However, the underlying mechanism has not been extensively explored. AIM OF THE STUDY: The purpose of this study was to investigate the effect and underlying mechanism of Zhen-Wu decoction on uremic cardiomyopathy, offering a potential target for clinical treatment of CRS type 4. MATERIALS AND METHODS: Five/six nephrectomized mice were utilized for experiments in vivo. The cardioprotective effects of Zhen-Wu decoction were evaluated by echocardiography and tissue staining. RNA-Seq data were used to investigate the potential pharmacological mechanism. The prediction of targets and active components was based on our previous strategy. Subsequently, the protective effect of the selected compound was verified in experiments in vitro. RESULTS: Zhen-Wu decoction alleviated cardiac dysfunction and endothelial injury in 5/6 nephrectomized mice, and the mechanism may involve the inflammatory process and oxidative stress. The activation of the Nrf2 signaling pathway was predicted to be a potential target of Zhen-Wu decoction in protecting endothelial cells. Through our machine learning strategy, we found that lactiflorin as an ingredient in Zhen-Wu decoction, alleviates IS-induced endothelial cell injury by blocking Keap1 and activating Nrf2. CONCLUSIONS: The present study demonstrated that Zhen-Wu decoction and lactiflorin could protect endothelial cells against oxidative stress in mice after nephrectomy by activating the Nrf2 signaling pathway.

Application experience in humans, a summary of the clinical practice of traditional Chinese medicine(TCM), serves as an important data source for evaluating the safety, effectiveness, and clinical value of drugs in the development of new Chinese medicine. The collected data serving as the evaluation evidence through statistical analysis are critical to the research on the application experience in humans. This article summarized and analyzed the data characteristics and statistical methodology of application experience of Chinese medicine in humans, and concluded the data types, outcome evaluation, bias evaluation, confounding factors, and missing values. Furthermore, the article emphasized the importance of data analysis of application experience of Chinese medicine in humans for TCM evidence and put forward the current difficulties, such as low data quality and large internal bias, lack of individualized data processing methods, and lack of methods for "disease-syndrome combination" data. We believe that with the development of methodology, the application experience of Chinese medicine in humans can strongly support the development of new drugs in TCM.

Nuanxinkang tablet (NXK), a Chinese herbal formula, can improve heart function and quality of life in patients with chronic heart failure (CHF). However, the mechanisms of action of NXK are not fully understood. In this study, we investigated the effects of NXK on inflammation in the CHF mouse model. This model was established by transverse aortic constriction (TAC) and treated with NXK for 8 weeks. Then, the cardiac function and myocardial fibrosis were evaluated. The monocytes/macrophages were evaluated by immunofluorescence. The mRNA levels of IL-1ß, IL-6, TNF-α, ICAM-1, and VCAM-1 were measured by quantitative real-time polymerase chain reaction (qRT-PCR), while TLR4, MyD88, NF-κB p65, P-IκBα, TLR2, TLR7 and TLR9 protein levels were evaluated by Western blot. The results showed that NXK improved the left ventricular ejection fraction (LVEF) and left ventricular end-systolic dimension, reversed myocardial fibrosis, and inhibited pro-inflammatory (CD11b + Ly6C+) monocytes/macrophages in the TAC mouse model. NXK also reduced the mRNA and protein levels of the above markers. Taken together, NXK improved heart function and reduced inflammation through the TLR-mediated NF-κB signaling pathway, suggesting that it might be used as an innovative treatment strategy for CHF.
RESUMO
BACKGROUND AND PURPOSE: Liquorice is the root of Glycyrrhiza glabra, which is a popular food in Europe and China that has previously shown benefits for skeletal fatigue and nutrient metabolism. However, the mechanism and active ingredients remain largely unclear. The aim of this study was to investigate the active ingredients of liquorice for muscle wasting and elucidate the underlying mechanisms. EXPERIMENTAL APPROACH: RNA-Seq and bioinformatics analysis were applied to predict the main target of liquorice. A machine learning model and a docking tool were used to predict active ingredients. Isotope labelling experiments, immunostaining, Western blots, qRT-PCR, ChIP-PCR and luciferase reporters were utilized to test the pharmacological effects in vitro and in vivo. The reverse effects were verified through recombination-based overexpression. KEY RESULTS: The liposoluble constituents of liquorice improved muscle wasting by inhibiting protein catabolism and fibre atrophy. We further identified FoxO1 as the target of liposoluble constituents of liquorice. In addition, hispaglabridin B (HB) was predicted as an inhibitor of FoxO1. Further studies determined that HB improved muscle wasting by inhibiting catabolism in vivo and in vitro. HB also markedly suppressed the transcriptional activity of FoxO1, with decreased expression of the muscle-specific E3 ubiquitin ligases MuRF1 and Atrogin-1. CONCLUSIONS AND IMPLICATIONS: HB can serve as a novel natural food extract for preventing muscle wasting in chronic kidney disease and possibly other catabolic conditions.
