Objective:To investigate the trademark registration situation of grade-A tertiary hospitals in China, so as to analyze the current situation of hospital brand protection and explore suggestions for hospital brand protection.Methods:The top 50 hospitals ranked in the 2021 National Hospital Comprehensive Ranking by the Hospital Management Research Institute of Fudan University, excluding military hospitals, were selected as the sample hospitals. The trademark registration information of the 50 sample hospitals was queried through the China Trademark Website of the Trademark Office of China National Intellectual Property Administration on March 15, 2023, and the registration of the full name, abbreviation, hospital emblem and other trademarks of the hospitals was counted. Results:Among the 50 sample hospitals, 26 hospitals already held hospital brand trademarks, which meant that at least one of the hospital′s full name, abbreviation, and emblem was registered as a trademark, accounting for 52%; 7 hospitals did not hold any trademarks, accounting for 14%; 17 hospitals held other trademarks but did not hold hospital brand trademarks, accounting for 34%. Among the 26 hospitals that already held brand trademarks, 11 hospitals only registered in one category. There were 3 hospitals with expired registered trademarks.Conclusions:Nearly half of the sample hospitals did not hold hospital brand trademarks, indicating that the trademark registration and brand protection of tertiary hospitals in China need to be strengthened. It is suggested to establish a hospital brand protection system, clarify the trademark management department, standardize the responsibilities of trademark management, and improve the use of trademarks, so as to do a good job in hospital trademark registration and brand protection.

Qingyan Dropping Pills have the effects of relieving wind and heat, detoxifying, and promoting the pharynx. It is commonly used in traditional Chinese medicines to treat acute and chronic pharyngitis, as well as sore throats and dry throats caused by surgery. Recently, many studies have shown that Qingyan Dropping Pills have certain effects on bacteriostasis, anti-inflammatory, antioxidant, and antiviral activities. As the coronavirus disease 2019 (COVID-19) pandemic enters the post-epidemic era, the regular use of drugs for COVID-19 pandemic symptoms has become a new trend. Therefore, there is a good market prospect to explore and develop Chinese patent medicines with antiviral effects. A preliminary study on the herbal formula and material basis of Qingyan Dropping Pills revealed that they have potential for antiviral applications. In this paper, the research on the quality study and antiviral effect of Qingyan Dropping Pills was reviewed, and the research direction of its secondary development was discussed to provide ideas and references for the new use of old traditional Chinese medicines.

Radiation protection drugs are often accompanied by toxicity, even amifostine, which has been the dominant radio-protecting drug for nearly 30 years. Furthermore, there is no therapeutic drug for radiation-induced intestinal injury (RIII). This paper intends to find a safe and effective radio-protecting ingredient from natural sources. The radio-protecting effect of Ecliptae Herba (EHE) was discovered preliminarily by antioxidant experiments and the mouse survival rate after ¹³⁷Cs irradiation. EHE components and blood substances in vivo were identified through UPLC‒Q-TOF. The correlation network of "natural components in EHE-constituents migrating to blood-targets-pathways" was established to predict the active components and pathways. The binding force between potential active components and targets was studied by molecular docking, and the mechanism was further analyzed by Western blotting, cellular thermal shift assay (CETSA), and ChIP. Additionally, the expression levels of Lgr5, Axin2, Ki67, lysozyme, caspase-3, caspase-8,8-OHdG, and p53 in the small intestine of mice were detected. It was found for the first time that EHE is active in radiation protection and that luteolin is the material basis of this protection. Luteolin is a promising candidate for RⅢ. Luteolin can inhibit the p53 signaling pathway and regulate the BAX/BCL2 ratio in the process of apoptosis. Luteolin could also regulate the expression of multitarget proteins related to the same cell cycle.

Rotundic acid(RA),an ursane-type pentacyclic triterpene acid isolated from the dried barks of Ilex rotunda Thunb.(Aquifoliaceae),possesses diverse bioactivities.To further study its pharmacokinetics,a simple and sensitive liquid chromatography with triple quadrupole mass spectrometry(LC-QqQ-MS/MS)method was developed and validated to quantify RA concentration in rat plasma and tissue using etofesalamide as an internal standard(IS).Plasma and tissue samples were subjected to one-step protein precipitation.Chromatographic separation was achieved on a ZORBAX Eclipse XDB-C18 col-umn(4.6 mm×50 mm,5 μm)under gradient conditions with eluents of methanol:acetonitrile(1∶1,V/V)and 5mM ammonium formate:methanol(9∶1,V/V)at 0.5mL/min.Multiple reaction monitoring transitions were performed at m/z 487.30 → 437.30 for RA and m/z 256.10 → 227.10 for IS in the negative mode.The developed LC-QqQ-MS/MS method exhibited good linearity(2-500 ng/mL)and was fully validated in accordance with U.S.Food and Drug Administration bioanalytical guidelines.Dose proportionality and bioavailability in rats were determined by comparing pharmacokinetic data after single oral(10,20,and 40 mg/kg)and intravenous(10 mg/kg)administration of RA.Tissue distribution was studied following oral administration at 20 mg/kg.The results showed that the absolute bioavailability of RA after administration at different doses ranged from 16.1％to 19.4％.RA showed good dose proportionality over a dose range of 10-40 mg/kg.RA was rapidly absorbed in a dose-dependent manner and highly distributed in the liver.In conclusion,this study is the first to systematically elucidate the absorption and distribution characteristics of RA in rats,which can provide additional information for further development and evaluation of RA in drug metabolism and pharmacokinetic studies.

Heart failure with high prevalence is the endpoint of many cardiovascular diseases. Once diagnosed， patients usually need lifelong medication， which seriously affects their quality of life. The drugs commonly used to treat heart failure include angiotensin-converting enzyme inhibitors， beta-blockers， aldosterone receptor antagonists， and diuretics. However， the long-term use of those drugs can lead to side effects such as hypotension， depletion of body fluid， and electrolyte imbalance and even increase mortality. According to the theory of traditional Chinese medicine （TCM）， Qi deficiency and blood stagnation is the major cause of heart failure and when Qi is not moving， blood is not flowing. Therefore， the TCM clinical treatment of heart failure uses the Chinese medicinal materials which replenish Qi， activate blood， and dispell stasis to treat both internal cause and external symptoms. Recent studies have demonstrated that Chinese herbal medicines such as Astragali Radix， Ginseng Radix et Rhizoma， Notoginseng Radix et Rhizoma， Salviae Miltiorrhizae Radix et Rhizoma， Angelicae Sinensis Radix， as well as the compound formulas such as Buyang Huanwutang， Simiao Yongantang， Qili Qiangxin capsules， and Qishen Yiqi drops， play a significant role in the prevention and treatment of heart failure via replenishing Qi， activating blood， and dispelling stasis. Inhibition of oxidative stress and inflammatory responses， mitigation of myocardial fibrosis， improvement of calcium cycling， and protection of mitochondrial function represent the key mechanisms for the treatment of heart failure with Chinese medicinal materials. Focusing on the pathogenic mechanisms and signaling pathways of heart failure， this paper systematically describes the pharmacological effects， molecular mechanisms， and research progress in the clinical application of Chinese medicinal herbs with effects of replenishing Qi， activating blood， and dispelling stasis and their compound formulas in the prevention and treatment of heart failure， aiming to provide scientific evidence for the development and clinical use of anti-heart failure Chinese medicinal materials.

Objective: Taxifolin is a natural flavonoid compound that can be isolated from onions, grapes, oranges and grapefruit. It also acts as a medicine food homology with extraordinary antioxidant and anti-inflammatory activity. This study aims to explain the protective effects and potential mechanisms of taxifolin against inflammatory reaction. Methods: Levels of interleukin (IL)-6, IL-1β and intracellular reactive oxygen species (ROS) were assessed in different time after the treatment of taxifolin in RAW264.7 cells induced by lipopolysaccharide (LPS). Subsequently, the mRNA and protein levels of inducible nitric oxide synthase (iNOS), vascular endothelial growth factor (VEGF), cyclooxygenase (COX)-2, tumor necrosis factor (TNF)-α and the phosphorylation expression levels of the MAPK signal pathway were also evaluated. A silico analysis was used to explain the binding situation for the investigation of taxifolin and MAPK signal pathway. And then MAPK inhibitors were used to reveal the expression level of iNOS, VEGF, COX-2 and TNF-α in RAW264.7 cells. Results: It was demonstrated that cell inflammatory damage induced by LPS was significantly alleviated after the treatment of taxifolin. Then, the mRNA and protein levels of iNOS, VEGF, COX-2 and TNF-α were reduced and the phosphorylation expression levels of the MAPK signal pathway were down-regulated remarkably as well. In silico analysis, taxifolin could form a relatively stable combination with MAPK signal pathway. MAPK inhibitors showed increasing or decreasing effect in the mRNA levels of iNOS, VEGF, COX-2 and TNF-α, which suggesting that taxifolin down-regulated iNOS, VEGF, COX-2 and TNF-α expressions were not entirely through the MAPK pathway. Conclusion: This finding demonstrated that taxifolin improved the inflammatory responses that partly involved in the phosphorylation expression level of MAPK signal pathway in RAW264.7 cells exposed to acute stress.

As the main body of providing medical and health services, public hospitals always bear the important responsibility of maintaining people′s life and health.In the period of normal epidemic prevention and control, public hospitals are also facing a series of new situations, including changes in social environment, demands for reform and development and transformation of target functions. It is urgent to solve many problems, such as inadequate capacity building, continuous heavy operational pressure, impact on traditional modes, and constant adjustment of positioning and mode.Therefore, both the state and the government should adhere to the public welfare as the fundamental standpoint, accelerate the implementation of scientific planning and balanced distribution of medical resources, through the fundamental adjustment of the system and mechanism, and actively help public hospitals to choose the appropriate development mode, as soon as possible to relieve pressure rescue; Public hospitals should actively make use of the extensive application of Internet and other technologies and the huge potential contained in scientific and technological innovation to achieve high-quality development goals of improving quality and efficiency, and provide more powerful support for the overall national strategy.

Over the past decade, traditional Chinese medicine (TCM) has widely embraced systems biology and its various data integration approaches to promote its modernization. Thus, integrative pharmacology-based traditional Chinese medicine (TCMIP) was proposed as a paradigm shift in TCM. This review focuses on the presentation of this novel concept and the main research contents, methodologies and applications of TCMIP. First, TCMIP is an interdisciplinary science that can establish qualitative and quantitative pharmacokinetics-pharmacodynamics (PK-PD) correlations through the integration of knowledge from multiple disciplines and techniques and from different PK-PD processes
