ObjectiveThis paper aims to clarify the material basis of Gualou Niubangtang and establish a quantitative analysis method for its main constituents, providing a reference for the overall quality control of this preparation. MethodsThe constituents in the formula were systematically characterized based on ultra-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS/MS). Identification was performed by matching with the UNIFI 9.6 software and utilizing database platforms such as PubChem, ChemicalBook, and ChemSpider, combined with relevant literature reports. A quantitative analysis method for the seven main constituents in Gualou Niubangtang was established by using high performance liquid chromatography (HPLC). ResultsUPLC-Q-TOF-MS/MS analysis identified 155 constituents, including 69 flavonoids, 36 terpenoids, 23 phenylpropanoids, 8 phenylethanoid glycosides, and 19 other types of constituents. In the established quantitative analysis method, the seven main constituents showed good linearity within their respective linear ranges. The precision, repeatability, stability, and spike recovery all met the required standards. The results showed that the content ranges of geniposide, liquiritin, hesperidin, arctiin, baicalin, oroxylin A-7-O-β-D-glucuronide, and wogonoside in 15 batches of Gualou Niubangtang were 13.67-21.25, 1.20-7.64, 5.45-7.45, 22.97-33.51, 29.95-39.07, 2.58-4.80, and 6.56-9.31 mg·g-1, respectively. ConclusionThis study successfully characterizes and attributes multi-category constituents in Gualou Niubangtang, clarifying that its material basis is primarily composed of flavonoids, terpenoids, phenylethanoid glycosides, and phenylpropanoids. Furthermore, it enables the quantification of seven constituents within the formula. This work lays a foundation for research on the quality control, action mechanism, and clinical application of this formula.

MethodsThroat swab samples were collected from 520 ILI cases in an influenza sentinel surveillance hospital in Anji County of Zhejiang Province from December 2023 to November 2024. Multiplex real-time fluorescence quantitative polymerase chain reaction (mRT-PCR) was used to detect 18 pathogens and their subtypes, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza A virus (Flu A), influenza A (H1N1) virus, influenza A (H3N2) virus, influenza B virus (Flu B), influenza B virus Victoria lineage (BV), influenza B virus Yamagata lineage (BY), coronavirus (CoV), human parainfluenza virus (HPIV), respiratory syncytial virus (RSV), human metapneumovirus (HMPV), adenovirus (ADV), human bocavirus (HBoV), enterovirus (EV), rhinovirus (RV), Mycoplasma pneumoniae (MP), Chlamydia pneumoniae (CP), and Streptococcus pneumoniae (SP). ResultsThe overall positivity rate of pathogens in 520 samples was 33.65%, among which the detection rates of Flu (9.14%), ADV (7.50%), SARS-CoV-2 (6.15%), and EV (3.65%) were relatively high. There were statistically significant differences in the overall positivity rate of pathogens by age and season (all P<0.05). The highest overall positivity rate was observed in the 5‒14 years old group (42.77%), and the overall positivity rate in winter (53.08%) was significantly higher than that in other seasons. ConclusionFrom 2023 to 2024, the main respiratory pathogens detected in ILI cases in Anji County were Flu, ADV, SARS-CoV-2, and EV. The epidemic characteristics showed age and seasonal specificity, so it is necessary to strengthen prevention and control for high-risk populations and epidemic seasons in a targeted manner.

BACKGROUND:Myocardial hypertrophy often leads to severe cardiovascular diseases and is difficult to diagnose due to its early stages being hard to detect.Circulating inflammatory proteins have been found to be significantly associated with cardiovascular diseases,yet the specific mechanisms linking them to myocardial hypertrophy remain unclear.OBJECTIVE:To investigate the relationship between circulating proteins and myocardial hypertrophy using multiple Mendelian randomization approaches.METHODS:Utilizing data from 91 circulating inflammatory proteins in the GWAS Catalog database and the latest myocardial hypertrophy data from the R11 FinnGen database,we employed bidirectional two-sample Mendelian randomization,multivariate Mendelian randomization,and Genome-Wide Association Studies co-localization to investigate the causal relationship between circulating inflammatory proteins and myocardial hypertrophy.The accuracy of the results was verified through sensitivity tests including MR-PRESSO,Cochran's Q test,MR-Egger intercept assessment,leave-one-out analysis,and funnel plot analysis.RESULTS AND CONCLUSION:In the results of two-sample Mendelian randomization,the primary method used for evaluation was the Inverse Variance Weighting(IVW)approach.It was found that the level of T-cell surface glycoprotein CD6 isoform(IVW:P=0.046,OR=0.74,95%Cl:0.66-1.00),level of slit chemokine(IVW:P=2.1×10-2,OR=0.74,95%CI:0.556-0.95),level of Delta and Notch-like epidermal growth factor-related receptor(IVW:P=3.7×10-4,OR=0.66,95%CI:0.49-0.87),level of interleukin-2(IVW:P=3.8×103,OR=0.667,95%CI:0.50-0.88),and sulfotransferase 1A1(IVW:P=1.42×102,OR=0.80,95%CI:0.67-0.96)had a unidirectional causal effect on cardiac hypertrophy.(2)Among the findings in multivariate Mendelian randomization,the levels of the CD6 isoform of T-cell surface glycoprotein(IVW:P=1.39×102,OR=0.81,95%CI:0.69-0.96)and the levels of Delta and Notch-like epidermal growth factor-related receptor(IVW:P=3.7×10-2,OR=0.73,95%CI:0.55-0.98)were positive,indicating that the results remained significant after excluding the effects of other circulating inflammatory proteins that had an impact on myocardial hypertrophy.(3)In colocalization,T-cell surface glycoprotein CD6 isoform levels had H3+H4=0.96,with the most significant single nucleotide polymorphism being rs59570070,suggesting an intrinsic link between T-cell surface glycoprotein CD6 isoform levels and myocardial hypertrophy.(4)Sensitivity results showed no abnormalities,indicating no heterogeneity or pleiotropic effects influencing the results.(5)These results verified that T cell surface glycoprotein CD6 isoforms,Slit chemokine,Delta and Notch-like epidermal growth factor-related receptors,interleukin-2,and sulfotransferase 1A1 had a unidirectional causal effect on myocardial hypertrophy.T cell surface glycoprotein CD6 isoforms and Delta and Notch-like epidermal growth factor-related receptors had the deepest impact,suggesting that there may be related pathways between T cell surface glycoprotein CD6 isoforms and myocardial hypertrophy.Mendelian randomization studies require large amounts of clinical data and therefore often use European samples from international databases for analysis.Since this analytical method has significant advantages in causal inference,precision medicine,and cross-population validation,its research results still hold great significance for the medical development in China.As Mendelian randomization research deepens,it also promotes the collection and analysis of clinical data in China to some extent.In the future,we can further analyze key protein mechanisms,combine multiomics and clinical validation,develop an inflammatory marker monitoring system and novel anti-inflammatory therapies,thereby promoting the prevention and control of cardiovascular diseases and the development of personalized medicine.

Ecoflex is a commercial designation for elastomers developed based on the principles of environmental sustainability and flexibility. Various manufacturers offer different types of Ecoflex products with distinct compositions and functions. Among these, the platinum-catalyzed silicone rubber Ecoflex series has demonstrated considerable applicability in various fields of oral medicine due to its excellent flexibility, biocompatibility, stability across a wide temperature range, and tunable mechanical properties. In tissue engineering, it can simulate the mechanical behavior of oral mucosa, and is used in cleft lip surgical training models and preoperative evaluation for temporal bone defect reconstruction. In the field of wearable devices, leveraging its encapsulation protection and flexible characteristics, highly sensitive sensors constructed from Ecoflex can monitor signals such as oral bite force and masticatory muscle activity, thereby aiding in the diagnosis of temporomandibular joint disorders and postoperative evaluation of cleft lip and palate. Moreover, when combined with bio-waste materials, it promotes the functionalization and sustainability of oral wearable devices.In drug delivery systems, its conformability and controlled-release capability address challenges in localized oral drug administration. Designs such as flexible microneedles and temperature-responsive composite systems provide precise solutions for treating periodontitis and oral ulcers. In minimally invasive surgical instruments, its softness enables the development of soft robots and magnetically controlled microfluidic valves, enhancing surgical safety and precision. In the field of oral rehabilitation, Ecoflex soft liner materials, inspired by the suction cup structure of octopus tentacles, improve denture retention. Their low modulus reduces mucosal irritation, ensuring both comfort and durability. Although Ecoflex shows great potential in biomedical applications, it still faces certain challenges, particularly regarding long-term stability after implantation, mechanical fatigue resistance, and microbial colonization, which require further investigation. In the future, with advancements in 3D printing technology, Ecoflex is expected to achieve more precise clinical translation across multiple fields and drive innovation in intelligent biomaterials.

Clinical and Molecular Hepatology 2026;32(2):866-883
Background/Aims:
Dysregulated cholesterol metabolism is a hallmark of hepatocellular carcinoma (HCC) that drives tumor initiation and progression. However, clinical targeting of cholesterol metabolism has yielded limited benefits due to stringent feedback in tumor cells. Identifying a central mediator capable of restoring cholesterol homeostasis within the cell’s intrinsically fine-tuned regulatory framework is urgently needed.
Methods:
We integrated a proteomic dataset from patients with cholesterol-dysregulated HCC into a global cholesterol metabolic regulatory network to identify potential therapeutic targets for disrupted cholesterol homeostasis. The prognostic significance of the candidate targets was further validated in an independent cohort through immunohistochemistry. Functional and mechanistic studies were conducted in vitro using HCC cell lines and in vivo using mouse models. The pharmacological efficacy of the candidate agent was evaluated in both subcutaneous and orthotopic HCC mouse models.
Results:
ER lipid raft-associated 1 (ERLIN1), a pivotal regulator of cholesterol metabolism reprogramming, was identified as an independent favorable prognostic indicator in HCC. ERLIN1 constrains HCC progression both in vitro and in vivo by stabilizing the INSIG1–SCAP–SREBP2 axis and maintaining the metabolic balance of intracellular cholesterol. Under hypoxia, impaired factor-inhibiting hypoxia-1-dependent hydroxylation of ASB11 at asparagine residues 90 and 92 enhances ASB11-mediated ERLIN1 degradation. Pharmacological targeting of this axis using zoledronic acid (ZoA) attenuated HCC progression by weakening the ASB11–ERLIN1 interaction and restoring cholesterol homeostasis.
Conclusions
ERLIN1 represents a druggable metabolic vulnerability in cholesterol-dysregulated HCC. Targeting the ASB11–ERLIN1 axis with the clinically approved ZoA reestablishes cholesterol homeostasis and offers a promising therapeutic strategy to overcome the current limitations of cholesterol-targeted HCC therapies.

Sonodynamic therapy (SDT) applies low-frequency ultrasound to activate sonosensitizers that have accumulated in tumor location, which induces cavitation effects and leads to the in-situ generation of reactive oxygen species (ROS), thereby achieving precise and efficient tumor treatment. Owing to its advantages such as deep tissue penetration and controllable treatment range, SDT has attracted significant attention and has been widely used in the research on the treatment of various tumors. While conventional treatment modalities have achieved significant efficacy in the treatment of hepatocellular carcinoma (HCC), there are still certain limitations. In this context, nanomedicine-based SDT leverages the targeting capabilities of nano-agents to realize specific killing of HCC cells, and furthermore, it can synergize with photodynamic therapy, chemotherapy, and immunotherapy to provide new opportunities for developing novel treatment modalities for HCC. This article reviews the mechanism of action of SDT and the advances in the research and application of SDT in the treatment of HCC, analyzes the shortcomings of existing studies, and proposes the directions for future development, in order to provide a theoretical foundation and scientific guidance for related research on HCC.

The scientific interpretation of the theory of medicinal properties of TCM is a research hotspot in the modernization of TCM. It is of great value to clarify the property and degree of cold and heat in Chinese materia medica for guiding clinical precise medication. In recent years, the research on the cold and heat properties of Chinese materia medica has been carried out at the animal, cell and molecular levels. Based on the objective material basis of medicinal properties, from the perspective of biological effects such as thermodynamics and multiomics; with the help of infrared thermal imaging and other technologies for analysis; forming a variety of research models such as "property-structure relationship". Related research has developed from a single material component or index to a new model that tends to integrate multi-source information and multi-dimensional data. However, how to deal with the problems of large sample size, strong redundancy, high heterogeneity, and how to integrate multi-dimensional information are still research difficulties. With its powerful computing and learning ability, machine learning can show good discrimination and prediction ability in the study of cold and hot properties of Chinese materia medica, and play an important role in the study of cold and hot properties of Chinese materia medica. At present, the most widely used algorithms are linear discriminant analysis, Logistic discriminant analysis, support vector machine, decision tree, random forest and so on. The data dimension of the existing research needs to be enriched, the algorithm has room for further optimization, and a more detailed discriminant model of cold and hot properties of Chinese materia medica needs to be established.
