ObjectiveIn order to provide a reference for the optimization of preparation process of stir-fried Glycyrrhizae Radix et Rhizoma(sf-GRR), the quality changes during the processing was studied. MethodsGlycyrrhizae Radix et Rhizoma was processed by stir-frying for 17 min, and samples were collected every 1 min during the processing. The appearance color of the samples was determined by visual analysis technology, the moisture and extract of the process samples were detected by the drying method and the hot extraction method of alcohol-soluble extract in the general rules of the 2020 edition of Chinese Pharmacopoeia(part Ⅳ), and the contents of liquiritin apioside, liquiritin, isoliquiritin apioside, isoliquiritin, licoricesaponin G2 and glycyrrhizic acid in the process samples were determined by high performance liquid chromatography(HPLC). Then principal component analysis(PCA), partial least squares-discriminant analysis(PLS-DA) and Spearman correlation analysis were used for clustering, discrimination and correlation analysis of the appearance color, moisture, extract and the contents of six internal components. Based on artificial neural network and random forest algorithm, the prediction model of processing degree of sf-GRR was established. On this basis, based on the five principles of quality marker(Q-Maker), explore the monitoring Q-Maker of sf-GRR. ResultsThe color of Glycyrrhizae Radix et Rhizoma deepened after stir-frying, and the appearance color of the sample changed from light yellow to dark yellow during processing. During the stir-frying process, the moisture content showed a decreasing trend with the extension of processing time, while the extract content showed an increasing trend with the extension of processing time. After stir-frying, the contents of liquiritin apioside, liquiritin and licoricesaponin G2 showed an overall decreasing trend, while the contents of isoliquiritin apioside and isoliquiritin increased, and the content of glycyrrhizic acid increased slightly. The correlation analysis showed that moisture was positively correlated with brightness(L*) and red/green value(a*), and negatively correlated with yellow/blue value(b*) and total color difference(E*ab). Isoliquiritin apioside and isoliquiritin had negative correlation with L* and a*, and positive correlation with b* and E*ab. The processing process of sf-GRR could be divided into two stages of the early stage(0-14 min) and the late stage(15-17 min), and could be divided into three stages of the early stage(0-6 min), the middle stage(7-14 min) and the late stage(15-17 min) by combining the moisture, extract, the contents of 6 components and color values. Based on artificial neural network analysis and random forest algorithm, isoliquiritin apioside, isoliquiritin, liquiritin and glycyrrhizic acid were selected as monitoring markers for sf-GRR. ConclusionBased on the analysis of the exterior-interior indicators of process samples of sf-GRR, this paper ultimately identifies four processing monitoring markers, which can provide a basis for optimizing the processing technology of sf-GRR.

Jianghuanglian is one of the representative processed products of Coptidis Rhizoma for treating cold syndrome with drugs of heat nature, and ginger is used to restrict the bitter cold of Coptidis Rhizoma, which can be traced back to Bojifang, and it is suitable for stagnation of damp-heat in middle-jiao, cold-heat mutual knots and other symptoms. Jianghuanglian retains the alkaloids, phenylpropanoids and flavonoids of Coptidis Rhizoma, and also introduces gingerol components such as 6-gingerol in ginger, which has pharmacological activities such as anti-inflammatory, antibacterial, anti-tumor, and improving gastrointestinal function. The 2020 edition of Chinese Pharmacopoeia and many local processing specifications have included the traditional processing process and quality standards of Jianghuanglian, but the specific process parameters and quality standards are incomplete, which limits the production and clinical application of this processed product. By summarizing the processing history, process research, quality evaluation, pharmacodynamic and medicinal property changes and application of Jianghuanglian in the past 20 years, there are differences in the processing methods and standards in various provinces and cities, which are mainly reflected in the preparation method, dosage, processing process and quantitative standards of ginger juice. In addition, there are also certain differences in the changes of the main components of Jianghuanglian prepared from ginger or dried ginger, as well as their efficacy and medicinal properties. The research on the processing process of Jianghuanglian plays an important role in improving its quality standards, and this review can provide a reference for improving the quality evaluation system of Jianghuanglian.

As an important part of Chinese traditional culture, the processing technology of traditional Chinese medicine(TCM) carries the wisdom of TCM for thousands of years, and its process is complex and rigorous. With the popularization of modern production technology, traditional processing techiques are facing the dual pressures from technological innovation and production standardization under the perspective of intangible cultural heritage. The modernization of TCM processing technology is an inevitable trend for industrial upgrading, but it cannot be separated from the foundation of traditional skills and ignore the core concepts and cultural values it embodies. Therefore, by analyzing the core characteristics of TCM processing technology and its differences with modern production, this paper discusses the establishment of a synergistic innovation mechanism between traditional techniques and modern technologies, the promotion of joint research and development between scientific research institutes and the industry, the strengthening of standardization of processing techniques, and the enhancement of social education and industry training to improve the recognition and inheritance of processing techniques in order to achieve the goal of innovation and protection of TCM processing technologies in the context of modernization, and to promote the high-quality development of the TCM processing industry.

RNA modifications constitute a crucial class of post-transcriptional chemical alterations that profoundly influence RNA stability and translational efficiency, thereby shaping cellular protein expression profiles. These diverse chemical marks are ubiquitously involved in key biological processes, including cell proliferation, differentiation, apoptosis, and metastatic potential, and they exert precise regulatory control over these functions. A major advance in the field is the recognition that RNA modifications do not act in isolation. Instead, they participate in complex, dynamic interactions—through synergistic enhancement, antagonism, competitive binding, and functional crosstalk—forming what is now termed the “RNA modification interactome” or “RNA modification interaction network.” The formation and functional operation of this interactome rely on a multilayered regulatory framework orchestrated by RNA-modifying enzymes—commonly referred to as “writers,” “erasers,” and “readers.” These enzymes exhibit hierarchical organization within signaling cascades, often functioning in upstream-downstream sequences and converging at critical regulatory nodes. Their integration is further mediated through shared regulatory elements or the assembly into multi-enzyme complexes. This intricate enzymatic network directly governs and shapes the interdependent relationships among various RNA modifications. This review systematically elucidates the molecular mechanisms underlying both direct and indirect interactions between RNA modifications. Building upon this foundation, we introduce novel quantitative assessment frameworks and predictive disease models designed to leverage these interaction patterns. Importantly, studies across multiple disease contexts have identified core downstream signaling axes driven by specific constellations of interacting RNA modifications. These findings not only deepen our understanding of how RNA modification crosstalk contributes to disease initiation and progression, but also highlight its translational potential. This potential is exemplified by the discovery of diagnostic biomarkers based on interaction signatures and the development of therapeutic strategies targeting pathogenic modification networks. Together, these insights provide a conceptual framework for understanding the dynamic and multidimensional regulatory roles of RNA modifications in cellular systems. In conclusion, the emerging concept of RNA modification crosstalk reveals the extraordinary complexity of post-transcriptional regulation and opens new research avenues. It offers critical insights into the central question of how RNA-modifying enzymes achieve substrate specificity—determining which nucleotides within specific RNA transcripts are selectively modified during defined developmental or pathological stages. Decoding these specificity determinants, shaped in large part by the modification interactome, is essential for fully understanding the biological and pathological significance of the epitranscriptome.

ObjectiveTo investigate the antiviral effect of Menispermi Rhizoma total alkaloids and its relationship with the type Ⅰ interferon (IFN-Ⅰ) signaling pathway. MethodThe effects of Menispermi Rhizoma total alkaloids on the intracellular replication of influenza A virus (H1N1), vesicular stomatitis virus (VSV), and cerebral myocarditis virus (EMCV) were detected by fluorescent inverted microscope, flow cytometry, Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and Western blot. A mouse model infected with H1N1 was constructed, and the mice were divided into a control group, H1N1 model group, Menispermi Rhizoma total alkaloids groups (10, 20, 30 mg·kg-1), and oseltamivir group (40 mg·kg-1), so as to study the effects on the weight and survival rate of infected mice. Real-time PCR was used to detect the activation effect of Menispermi Rhizoma total alkaloids on the IFN-Ⅰ pathway in cells, and the relationship between the antiviral effect of Menispermi Rhizoma total alkaloids in IFNAR1 knockout A549 cells (IFNAR1-/--A549) and IFN-Ⅰ pathway was detected. ResultCompared with the control group, the virus proliferated significantly in the model group (P<0.01). Compared with the model group, Menispermi Rhizoma total alkaloids could significantly inhibit the replication of H1N1, VSV, and EMCV in vitro (P<0.01), inhibit the weight loss of the mice infected with the H1N1 in vivo, and improve the survival rate of mice (P<0.05). In addition, Menispermi Rhizoma total alkaloids activated the IFN-I pathway and relied on this pathway to exert the function of antiviral infection. ConclusionMenispermi Rhizoma total alkaloids exert antiviral effects in vivo and in vitro by activating the IFN-Ⅰ pathway.
