    With the increasing public concern over drug safety and the ongoing advancement of generic drug consistency evaluation in China, the critical role of pharmaceutical excipients has garnered heightened recognition. Based on an in-depth analysis of the definition and properties of pharmaceutical excipients, this study references international research on atypical active substances and reveals that certain excipients can directly function as active pharmaceutical ingredients in drug formulations. Building on this finding, the concept of “medicine and excipient homology” is proposed and comprehensively elaborated, supported by examples of common excipients exhibiting this dual characteristic. Furthermore, the current regulatory frameworks for such excipients in China and other countries are comparatively analyzed, highlighting existing challenges and actionable recommendations are proposed to refine the precision management of pharmaceutical excipient quality in China, aiming to enhance drug efficacy and safety through improved excipient governance.

    Objective: To explore the relationship between government subsidies and innovation efficiency of rare disease drug companies. Methods: This study is based on the panel data of 16 selected rare disease drug pharmaceutical listed companies from 2018 to 2023. Firstly, dynamic and static efficiency analysis was conducted using data envelopment analysis (DEA), and secondly, empirical analysis was conducted using benchmark regression and semi-parametric estimation models. Results: In the DEA results, only Shanghai Pharmaceutical's efficiency value was 1.000, and 56.25% of the enterprises showed a decreasing trend in efficiency, with an average annual decrease of 0.070% in total factor productivity. In the benchmark regression analysis, the regression coefficient of government subsidies was -0.087, which is significant at the 5% level. In the semi-parametric analysis, the partial derivative of government subsidies on innovation efficiency was an exponential change. Conclusion: Except for Shanghai Pharmaceutical, the innovation efficiency of other enterprises has not reached an effective state, showing an overall decreasing trend in efficiency. The current government subsidies have failed to achieve the effect of effectively improving the level of innovation efficiency of pharmaceutical enterprises. Therefore, the relevant government departments must formulate incentive policies for rare diseases, provide government subsidies on an ongoing basis, and gradually improve the R&D efficiency of domestic pharmaceutical enterprises in the development of drugs for rare diseases.

    The drug  treatment related to dyslipidemia is currently a hot research topic in the cardiovascular field. Dyslipidemia is closely related to cardiovascular diseases, especially hyperlipidemia. Autophagy refers to a phenomenon that damaged or excess organelles and proteins are decomposed in lysosomes, which plays an important role in maintaining cell homeostasis and coping with external environmental pressure. Autophagy also plays an important role in lipid metabolism. Autophagy can degrade lipid droplets and reduce lipid deposition, thus maintaining the homeostasis of lipid metabolism. Our previous study found that autophagy may regulate hepatocyte autophagy by regulating the expression of key enzymes of lipid metabolism, thus affecting the homeostasis of liver lipid metabolism. Different autophagy regulation pathways play different roles in the process of lipid metabolism in liver, and interact with the lipolysis pathway mediated by traditional lipase. In this paper, the research progress of new lipid-lowering drugs that affect lipid metabolism by regulating autophagy is systematically reviewed.

    Echinocandin are semi synthetic antibiotics. In the process from strain fermentation to clinical use, process impurities or degradation impurities are easily introduced into these drugs. The above impurities usually have complex structures and are similar to the structures of active components, so they may compete with drugs for the target of action and affect the safety and effectiveness of drugs. Therefore, it is important to study the sources and structures of impurities for the quality control of drugs. This review summarizes the pharmacopoeia inclusion of echinocandin, the precursor structure and the development process of structural modification, and analyzes the possible sources of impurities, structures and quality control, so as to provide a reference for the quality research and control of echinocandin.

    Vasomotor symptoms (VMS) are the hallmark symptom of menopausal women. Menopausal hormone therapy (MHT), the first-line treatment for VMS, has been limited in some target populations due to concerns about its venous thromboembolic risk and breast safety. Neurokinin 3 receptor (NK3R) antagonists are a new type of non-hormonal oral drug for the treatment of VMS in menopausal women. They prevent the over-activation of kisspeptin/neurokinin B/dynorphin (KNDy) neurons by blocking the binding of neurokinin B (NKB) to KNDy neurons, reduce the sensitivity of hypothalamic thermoregulatory centers, and restore normal thermoregulatory function, thus reduce the frequency and severity of hot flushes and night sweats. In this article, we will focus on reported NK3R antagonists and their clinical value in the treatment of VMS.

    Objective: To investigates the mechanism by which Liang-Fu Dropping Pills regulate the PI3K-AKT signaling pathway to exert an anti-gastric ulcer effect. Methods: First, the prepared Liang-Fu Dropping Pills, Alpinia officinarum, and Rhizoma Cyperi extracts were respectively detected and analyzed by ultra-high performance liquid chromatography-quadrupole-electrostatic orbitrap high-resolution mass spectrometry (UHPLC-Q-Exactive Plus Orbitrap HRMS). Subsequently, the potential pharmacological substances and potential mechanisms of action for the anti-gastric ulcer of Liang-Fu Dropping Pills were predicted through network pharmacology. Finally, in vivo experiments were conducted to investigate the anti-gastric ulcer effect of Liang-Fu Dropping Pills by observing the apparent morphology of the stomach and examining the stained tissues using histological staining methods. Real-time quantitative PCR and Western blotting were used to verify the regulatory effect of Liang-Fu Dropping Pills on potential targets in rat tissues of gastric ulcer model. Results: A total of 77 chemical constituents were identified from the extract of Liang-Fu Dropping Pills. Pathway enrichment analysis of chemical constituents and common targets of gastric ulcer disease showed that the anti-gastric ulcer mechanism of Liang-Fu Dropping Pills might be related to the regulation of lipid metabolism and PI3K-AKT signaling pathways. Molecular docking showed that protein kinase B1 (AKT1) and cellular tumor antigen P53 (TP53) were well combined with galangin and rhamnocitrin, the main index components of Liang-Fu Dropping Pills. In vivo experimental results showed that Liang-Fu Dropping Pills could significantly increase the level of acidic mucopolysaccharide (P<0.05) in the gastric mucosa, and significantly down-regulate the mRNA and protein expression levels of p-PI3K/PI3K (P<0.01), p-AKT/AKT (P<0.001), nuclear factor-kappa B p65 [NF-κB p65 (P<0.001)] and TP53 (P<0.01) in the gastric ulcer tissue of rats. Conclusion: In this study, we preliminarily explored the mechanism of the anti-gastric ulcer effect of Liang-Fu Dropping Pills through network pharmacology and animal experiments, which may be related to the regulation of PI3K-AKT related signaling pathway, which provided a reference for in depth study of the pharmacodynamic material basis and mechanism of action Liang-Fu Dropping Pills.

    Objective: To assess the cost-effectiveness of ribociclib combined with endocrine therapy versus endocrine therapy alone for premenopausal patients with HR+/HER2- advanced or metastatic breast cancer from the perspective of the Chinese healthcare system, providing references for healthcare decision-making. Methods: Based on the clinical efficacy data from the phase Ⅲ MONALEESA-7 trial, a partitioned survival model was constructed with a cycle length of four weeks and a time horizon of 20 years. The model evaluated differences in total costs, life years (LYs), quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER) between ribociclib combined with endocrine therapy and endocrine therapy alone in terms of long-term health and economic benefits. The model's robustness was tested using one-way sensitivity analysis, probabilistic sensitivity analysis, and scenario analysis. Results: The base case analysis indicated that ribociclib combined with endocrine therapy was clinically superior to endocrine therapy alone, providing an additional 0.86 QALYs at an incremental cost of CNY 234 623.99, with an ICER of 272 632.70 CNY·QALY-1. One-way sensitivity analysis showed that the three most influential factors on ICER were the utility value of progression-free survival, discount rate, and cost of ribociclib. The results of the probabilistic sensitivity analysis indicate that when the willingness-to-pay (WTP) threshold was set at three times the per capita GDP of China in 2023 (268 074 CNY·QALY-1), the probability of the ribociclib combined endocrine therapy regimen being cost-effective was 45%. Scenario analysis showed that with longer simulation time horizons, the ICER of the ribociclib combined with endocrine therapy gradually decreased, with the magnitude of decrease diminishing. Conclusion: At a WTP of 268 074 CNY·QALY-1, ribociclib combined with endocrine therapy is not cost-effective compared to endocrine therapy alone for the first-line treatment of premenopausal patients with HR+/HER2- advanced or metastatic breast cancer.
