Lu Q, Schulz PJ, Chang A. Medication safety perceptions in China: Media exposure, healthcare experiences, and trusted information sources. PATIENT EDUCATION AND COUNSELING 2024; 123:108209. [PMID: 38367304 DOI: 10.1016/j.pec.2024.108209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 01/01/2024] [Accepted: 02/12/2024] [Indexed: 02/19/2024]
Abstract
OBJECTIVE Amid ongoing medication safety concerns in China and limited research on public perceptions, this study investigates the correlations between media exposure, healthcare experiences, and individuals' perceptions of medication safety. It also examines individuals' reliance on information sources during safety crises. METHODS A multistage stratified random sampling was employed with the gross sample containing 3090 Chinese adults aged 18-60 years. Data were analyzed using multiple linear regression. RESULTS Social media exposure was found to negatively correlate with perceptions of current medication safety and its perceived improvement, while exposure to television and print media showed positive correlations. Positive healthcare experiences were associated with improved medication safety perceptions. Among various information sources, healthcare professionals were deemed most trustworthy during medication safety incidents. CONCLUSIONS Media exposure and personal healthcare experiences significantly shape individuals' perceptions of medication safety in China, with healthcare professionals playing a crucial role in this context. Practiceimplications: Effective health crisis communication in China needs to be multifaceted, integrating traditional media and social media platforms to disseminate accurate information broadly. Additionally, healthcare professionals should be actively involved in crisis communication. Their role as trusted sources can be leveraged to clarify misconceptions, and reassure the public during medication safety incidents.

Abstract
INTRODUCTION The Chinese National Medical Products Administration (NMPA) has emphasized proactive pharmacovigilance throughout the product life cycle in recent years. However, the safety-related withdrawal of drugs from the Chinese market has received less attention. OBJECTIVES The primary aim of the study was to investigate the context of withdrawing a drug for safety reasons in China (between 1999 and 2021). METHODS Withdrawn drugs were first identified from the Chinese NMPA and United States (US) Food and Drug Administration websites and the World Health Organization's (WHO's) consolidated list of products, WHO Drug Information, and WHO Pharmaceuticals Newsletter. We then searched the China National Knowledge Internet database, Chongqing VIP information database, Wanfang database, PubMed, and Google Scholar for drug withdrawal details. We used the Oxford Centre for Evidence-Based Medicine criteria to assess the levels of evidence that support withdrawing a drug. RESULTS A total of 30 drugs were withdrawn from the Chinese market between 1999 and 2021. The number of withdrawals increased during the stable Chinese drug surveillance period (2012-2021). Evidence from case-series or case-control studies was primarily used to determine the withdrawals of 16 drugs (53.3%). Fifteen drugs were withdrawn from the markets of China and the US, including five drugs (5/15, 33.3%) that were withdrawn in the same year in China and the US. CONCLUSIONS The promulgation of regulations and development of advanced passive and active systems have enhanced pharmacovigilance in China. High-quality evidence, coordination with other regulatory authorities, and communication and information sharing should be strengthened to optimize drug safety surveillance and risk management.

Abstract
BACKGROUND Pharmacovigilance is a science that plays a significant role in reducing ADRs and helps predict adverse reactions to drugs in community. To safely use drugs in treatment and prevention of disease, adverse drug reaction has been paid more attention. OBJECTIVES To evaluate the future needs of existing systems, the paper investigated the current state of pharmacovigilance and the reporting of ADR in Chinese hospitals. METHODS This cross-sectional, questionnaire-based study involved 10,063 pharmacists, doctors, and nurses from primary, secondary, and tertiary hospitals in all 31 provinces of China. It was commissioned by the National Centre for ADR Monitoring of China and conducted in March 2020. Three areas were assessed: sociodemographic characteristics of participants, awareness of the pharmacovigilance system, and the current state of hospitals' reporting of ADRs. Chi-square tests were used to calculate P values. RESULTS Health care professionals had heard the term "pharmacovigilance" previously (89.40%) and knew the reporting object (68.47%), content (65.94%), and range (64.83%) of pharmacovigilance. Most hospitals dispatched responsible professionals (87.64%) and departments (86.25%) to monitor ADR reporting. A total of 58.66% of tertiary medical, 45.25% of secondary, and 38.90% of primary hospitals extracted ADRs from a hospital information system. Moreover, 53.09% of tertiary medical, 38.93% of secondary, and 23.89% of primary hospitals had established a prescription automatic screening system to warn about risks for ADRs. Health care professionals' reports (99.92%) and patient feedback (77.99%) were included in most hospitals' ADR reporting. CONCLUSIONS Chinese health care professionals generally have good awareness of pharmacovigilance, and pharmacovigilance is relatively more advanced in China compared to other developing countries.

Abstract
The systematic safety surveillance of real-world use of medicinal products and related activities (pharmacovigilance) started in earnest as a scientific field only in the 1960s. While developments have occurred over the past 50 years, adding to its complexity and sophistication, the extent to which some of these advances have positively impacted the capability for ensuring patient safety is questionable. We review how the conduct of safety surveillance has changed, highlight recent scientific advances, and argue how they need to be harnessed to enhance pharmacovigilance in the future. Specifically, we describe five changes that we believe should and will need to happen globally in the coming years: (i) better, more diverse data used for safety; (ii) the switch from manual activities to automation; (iii) removal of limited value, extraneous transactional activities and replacement with sharpened focus on scientific efforts to improve patient safety; (iv) patient-involved and focussed safety; and (v) personalised safety.

Abstract
In this study, we explored the quality consistent evaluation method of Yankening Tablets (YKNT) from different manufacturers by using multiple fingerprint profiles, including dual-wavelength ultra-high performance liquid chromatography (UPLC) serial fingerprint and Fourier Transform Infrared Spectroscopy (FT-IR) fingerprint, combined with quantitative analysis of multi-components by single marker (QAMS) method. In the Average method of systematic quantified fingerprint method (AMSQFM), three fingerprint parameters of macro qualitative similarity (Sm-UPLC-FTIR), macro quantitative similarity (Pm-UPLC-FTIR), and the variation coefficient of fingerprint homogeneity (αUPLC-FTIR) were calculated based on the ratio method. The Sm-UPLC-FTIR values of all the samples were greater than 0.80, the αUPLC-FTIR values were less than 0.20, and the Pm-UPLC-FTIR values range from 72.8% to 119.8%. Method validation results showed the established fingerprint method had good precision, solution stability, and method repeatability, all samples could be roughly divided into different levels. The contents of berberine (BBR) and baicalin (BCL) measured by the calibration curve method (CCM) and QAMS method were compared, and t-test results (Pvalue > 0.05) indicated there was no significant difference between the two methods, which showed that QAMS could accurately quantify the markers of the YKNT. The explanatory ability (R2Y) values of BBR and BCL in the PLS model were both greater than 0.94, and the root mean square error of estimation (RMSEE) and root mean square error of prediction (RMSEP) values were both less than 2.5, indicating that the established model was reliable. Hierarchical cluster analysis divided all samples into four categories. This research made a major contribution to the quality consistent evaluation of Traditional Chinese Medicine (TCM) and food.

Shuganning injection, a traditional Chinese patent medicine, induces ferroptosis and suppresses tumor growth in triple-negative breast cancer cells. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 85:153551. [PMID: 33827043 DOI: 10.1016/j.phymed.2021.153551] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 02/27/2021] [Accepted: 03/12/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Triple-negative breast cancer (TNBC), lacking targeted therapies currently, is susceptible to ferroptosis, a recently defined form of cell death. PURPOSE To evaluate the anticancer activity of Shuganning injection (SGNI), a traditional Chinese patent medicine, on TNBC cells; To elucidate the mechanism of SGNI induced ferroptosis. METHODS The anticancer activity of SGNI was examined via in vitro cell proliferation assays and in vivo xenograft growth assay. Ferroptosis was determined by flow-cytometric analysis of lipid ROS, labile iron pool measurement, and propidium iodide exclusion assay. The dependency on heme oxygenase 1 (HO-1) of SGNI induced ferroptosis was confirmed by genetic knockdown and pharmacological inhibition of the protein. RESULTS SGNI selectively inhibited the proliferation of TNBC cells compared to non-TNBC breast cancer cells and normal cells. The cell death induced by SGNI in TNBC cells showed distinct morphology from apoptosis and could not be rescued by the pan-caspase inhibitor Z-VAD(OMe)-FMK. On the other hand, SGNI induced cell death was blocked by the lipid ROS scavengers ferrostatin-1 and liproxstatin-1, the acyl-CoA synthetase long chain family member 4 inhibitor rosiglitazone, and the iron chelators 1,10-phenanthroline and deferoxamine. These data indicated that SGNI induced a ferroptotic cell death of TNBC cells. Mechanistically, SGNI induced ferroptosis was dependent on HO-1, which promotes intracellular labile iron pool accumulation, and was alleviated by HO-1 knockdown and inhibition by tin protoporphyrin IX. In line with the in vitro data, SGNI significantly inhibited the xenograft growth of TNBC cell line MD-MB-231 in nude mice. CONCLUSION Collectively, our study elaborates on a promising regimen for TNBC treatment through induction of ferroptosis by SGNI, a traditional Chinese patent medicine currently available in the clinic, which merits further investigation.

Pharmacoepidemiol Drug Saf 2021; 30:636-643. [PMID: 33630347 DOI: 10.1002/pds.5215] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Accepted: 02/21/2021] [Indexed: 11/10/2022]
Abstract
PURPOSE Little is known about emergency hospitalizations owing to adverse drug events (ADEs) in Chinese populations. The aim of this study was to identify the types and characteristics of ADEs as well as estimate the length of hospital stay and ADE-related costs in a hospital emergency setting in China. METHODS This prospective study was conducted in the emergency department of our hospital from April 1, 2017 to December 31, 2019. ADEs of patients admitted to the emergency department were collected by a clinical pharmacist during daily pharmacy rounds. RESULTS Of 4020 cases admitted to the emergency department, 198 emergency ADE-related hospitalizations (4.93%) were noted, which were classified into certain (n = 0, 0%), probable (n = 122, 61.6%), and possible (n = 76, 38.4%). The ADE was serious in 93.9% of the 198 cases. Ten cases were fatal, and two cases were life-threatening. More than 80% of the emergency ADE-related hospitalization cases were of patients over 60 years. The pharmacological agents implicated in the hospitalizations were oral antiplatelet agents (20.7%), oral hypoglycemic agents (16.7%), insulin (11.1%), and antihypertensive agents (9.1%). The average length of ADE-related hospital stay was 10 (7.0-14.0) days. ADE-related costs ranged from $1684.68 to $4531.35 for each hospitalization. The length of ADE-related hospital stay and associated costs were statistically significant. Most ADEs (n = 146, 73.7%) were preventable. CONCLUSIONS Most emergency ADE-related hospitalizations in older adults resulted from lack of medication monitoring or inappropriate medication. Improved management of medicines by clinical pharmacists has the potential to reduce ADE-related hospitalizations in older adults in China.

Abstract
With the tremendous growth of scientific literature in recent years, methods of detecting and analysing research topics have become more and more important. This study proposes a topic analysis method combining latent Dirichlet allocation (LDA) and a three-dimensional strategic diagram. This study constructs the three-dimensional strategic diagram by three dimensions of centrality, density and novelty, and we classify topics into seven categories according to their strategic positions. Using this topic analysis method, the paper analyses 62,340 publications in the field of medical informatics between 1991 and 2018. Results show that the research scope of medical informatics has become increasingly interdisciplinary. Data analytical methods and technologies are sub-domains with persistent popularity. New health technologies, drug safety, algorithm optimisation and standardisation of medical information are emerging research topics. We hope the findings could help researchers identify potential research topics and facilitate in-depth analysis of the current state of various fields.
