Understanding Pitfalls and Opportunities of Applying Heuristic Evaluation Methods to VR Training Systems: An Empirical Study.

The usability of virtual reality (VR) training applications is crucial for their success, but examining the usability in the early development stages remains challenging. A realistic and plausible solution would be revisiting and reconciling Heuristics Evaluation (HE) methods among the most widely used usability inspection methods in the human-computer interaction (HCI) domain. While research on studying and using HE methods is growing within the VR domain, few studies have considered the novel VR environment challenges new requirements for fitting HE methods to the context and applying them effectively. To this end, we conducted a user study with 14 evaluators using the standard HE methods to complete two HE sessions for a VR training application. We identified five critical challenges that evaluators encountered in the HE process by observing and interviewing them. Based on our findings, we discuss the importance of considering an easy-to-use heuristic set, how we can facilitate the HE procedures in the VR context, and the opportunities for developing HE-supporting tools.

Methods, Indicators, and End-User Involvement in the Evaluation of Digital Health Interventions for the Public: Scoping Review.

BACKGROUND: Digital health interventions (DHIs) have the potential to enable public end users, such as citizens and patients, to manage and improve their health. Although the number of available DHIs is increasing, examples of successfully established DHIs in public health systems are limited. To counteract the nonuse of DHIs, they should be comprehensively evaluated while integrating end users. Unfortunately, there is a wide variability and heterogeneity according to the approaches of evaluation, which creates a methodological challenge. OBJECTIVE: This scoping review aims to provide an overview of the current established processes for evaluating DHIs, including methods, indicators, and end-user involvement. The review is not limited to a specific medical field or type of DHI but offers a holistic overview. METHODS: This scoping review was conducted following the JBI methodology for scoping reviews based on the framework by Arksey & O'Malley and complies with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. Three scientific databases (PubMed, Scopus, and Science Direct) were searched in April 2023. English and German studies between 2008 and 2023 were considered when evaluating DHIs that explicitly address public end users. The process of study selection was carried out by several researchers to avoid reviewer bias. RESULTS: The search strategy identified 9618 publications, of which 160 were included. Among these included articles, 200 evaluations were derived and analyzed. The results showed that there is neither a consensus on the methods to evaluate DHIs nor a commonly agreed definition or usage of the evaluated indicators, which results in a broad variety of evaluation practices. This aligns with observations of the existing literature. It was found that there is a lack of references to existing frameworks for the evaluation of DHIs. The majority of the included studies referred to user-centered approaches and involved end users in the evaluation process. As assistance for people developing and evaluating DHIs and as a basis for thinking about appropriate ways to evaluate DHIs, a results matrix was created where the findings were combined per DHI cluster. Additionally, general recommendations for the evaluators of DHIs were formulated. CONCLUSIONS: The findings of this scoping review offer a holistic overview of the variety and heterogeneity according to the approaches of evaluation of DHIs for public end users. Evaluators of these DHIs should be encouraged to reference established frameworks or measurements for justification. This would ease the transferability of the results among similar evaluation studies within the digital health sector, thereby enhancing the coherence and comparability of research in this area.

Advancing bone regeneration: Unveiling the potential of 3D cell models in the evaluation of bone regenerative materials.

Bone, a rigid yet regenerative tissue, has garnered extensive attention for its impressive healing abilities. Despite advancements in understanding bone repair and creating treatments for bone injuries, handling nonunions and large defects remains a major challenge in orthopedics. The rise of bone regenerative materials is transforming the approach to bone repair, offering innovative solutions for nonunions and significant defects, and thus reshaping orthopedic care. Evaluating these materials effectively is key to advancing bone tissue regeneration, especially in difficult healing scenarios, making it a critical research area. Traditional evaluation methods, including two-dimensional cell models and animal models, have limitations in predicting accurately. This has led to exploring alternative methods, like 3D cell models, which provide fresh perspectives for assessing bone materials' regenerative potential. This paper discusses various techniques for constructing 3D cell models, their pros and cons, and crucial factors to consider when using these models to evaluate bone regenerative materials. We also highlight the significance of 3D cell models in the in vitro assessments of these materials, discuss their current drawbacks and limitations, and suggest future research directions. STATEMENT OF SIGNIFICANCE: This work addresses the challenge of evaluating bone regenerative materials (BRMs) crucial for bone tissue engineering. It explores the emerging role of 3D cell models as superior alternatives to traditional methods for assessing these materials. By dissecting the construction, key factors of evaluating, advantages, limitations, and practical considerations of 3D cell models, the paper elucidates their significance in overcoming current evaluation method shortcomings. It highlights how these models offer a more physiologically relevant and ethically preferable platform for the precise assessment of BRMs. This contribution is particularly significant for "Acta Biomaterialia" readership, as it not only synthesizes current knowledge but also propels the discourse forward in the search for advanced solutions in bone tissue engineering and regeneration.

Taste-masking methods in multiparticulate dosage forms with a focus on poorly soluble drugs.

In the past, the administration of medicines for children mainly involved changes to adult dosage forms, such as crushing tablets or opening capsules. However, these methods often led to inconsistent dosing, resulting in under- or overdosing. To address this problem and promote adherence, numerous initiatives, and regulatory frameworks have been developed to develop more child-friendly dosage forms. In recent years, multiparticulate dosage forms such as mini-tablets, pellets, and granules have gained popularity. However, a major challenge that persists is effectively masking the bitter taste of drugs in such formulations. This review therefore provides a brief overview of the current state of the art in taste masking techniques, with a particular focus on taste masking by film coating. Methods for evaluating the effectiveness of taste masking are also discussed and commented on. Another important issue that arises frequently in this area is achieving sufficient dissolution of poorly water-soluble drugs. Since the simultaneous combination of sufficient dissolution and taste masking is particularly challenging, the second objective of this review is to provide a critical summary of studies dealing with multiparticulate formulations that are tackling both of these issues.

Using brief reflections to capture and evaluate end-user engagement: a case example using the COMPASS study.

BACKGROUND: Use of participatory research methods is increasing in research trials. Once partnerships are established with end-users, there is less guidance about processes research teams can use to successfully incorporate end-user feedback. The current study describes the use of a brief reflections process to systematically examine and evaluate the impact of end-user feedback on study conduct. METHODS: The Comparative Effectiveness of Trauma-Focused and Non-Trauma- Focused Treatment Strategies for PTSD among those with Co-Occurring SUD (COMPASS) study was a randomized controlled trial to determine the effectiveness of trauma-focused psychotherapy versus non-trauma-focused psychotherapy for Veterans with co-occurring posttraumatic stress disorder and substance use disorder who were entering substance use treatment within the Department of Veterans Affairs. We developed and paired a process of "brief reflections" with our end-user engagement methods as part of a supplemental evaluation of the COMPASS study engagement plan. Brief reflections were 30-minute semi-structured discussions with the COMPASS Team following meetings with three study engagement panels about feedback received regarding study issues. To evaluate the impact of panel feedback, 16 reflections were audio-recorded, transcribed, rapidly analyzed, and integrated with other study data sources. RESULTS: Brief reflections revealed that the engagement panels made recommended changes in eight areas: enhancing recruitment; study assessment completion; creating uniformity across Study Coordinators; building Study Coordinator connection to Veteran participants; mismatch between study procedures and clinical practice; therapist skill with patients with active substance use; therapist burnout; and dissemination of study findings. Some recommendations positively impact study conduct while others had mixed impact. Reflections were iterative and led to emergent processes that included revisiting previously discussed topics, cross-pollination of ideas across panels, and sparking solutions amongst the Team when the panels did not make any recommendations or recommendations were not feasible. CONCLUSIONS: When paired with end-user engagement methods, brief reflections can facilitate systematic examination of end-user input, particularly when the engagement strategy is robust. Reflections offer a forum of accountability for researchers to give careful thought to end-user recommendations and make timely improvements to the study conduct. Reflections can also facilitate evaluation of these recommendations and reveal end-user-driven strategies that can effectively improve study conduct. TRIAL REGISTRATION: ClinicalTrials.gov (NCT04581434) on October 9, 2020; https://clinicaltrials.gov/ct2/show/study/NCT04581434?term=NCT04581434&draw=2&rank=1 .

In vivo safety evaluation method for nanomaterials for cancer therapy.

Nanomaterials are extensively used in the diagnosis and treatment of cancer and other diseases because of their distinctive physicochemical properties, including the small size and ease of modification. The approval of numerous nanomaterials for clinical treatment has led to a significant increase in human exposure to these materials. When nanomaterials enter organisms, they interact with DNA, cells, tissues, and organs, potentially causing various adverse effects, such as genotoxicity, reproductive toxicity, immunotoxicity, and damage to tissues and organs. Therefore, it is crucial to elucidate the side effects and toxicity mechanisms of nanomaterials thoroughly before their clinical applications. Although methods for in vitro safety evaluation of nanomaterials are well established, systematic methods for in vivo safety evaluation are still lacking. This review focuses on the in vivo safety evaluation of nanomaterials and explores their potential effects. In addition, the experimental methods for assessing such effects in various disciplines, including toxicology, pharmacology, physiopathology, immunology, and bioinformatics are also discussed.

Study on the Freeze-Thaw Resistance of Concrete Pavements in Seasonally Frozen Regions.

In seasonally frozen regions, concrete pavement is exposed to cycles of freeze-thaw and erosion from de-icing salt, which can lead to unfavorable service conditions and vulnerability to damage. This paper examines the compressive strength, flexural-tensile strength, abrasion resistance, permeability, and spacing factor of concrete, taking into account the impact of various curing conditions, de-icing salt solutions, and mass fractions on the concrete's freeze-thaw resistance. Two test methods, the single-face method and the fast-freezing method, were used to comparatively analyze the freeze-thaw resistance of concrete. The analysis was based on the surface scaling, water absorption rate, mass loss rate, relative dynamic elastic modulus, and relative durability index. The results indicate that the presence of salt solution significantly worsened the degree of concrete damage caused by freeze-thaw cycles. The use of freeze-thaw media, specifically sodium chloride (NaCl), calcium chloride (CaCl2), and potassium acetate (KAc) at mass fractions of 5%, 4.74%, and 5%, respectively, had the greatest impact on the surface scaling of concrete. However, their effect on the water absorption rate was inconsistent. When the freeze-thaw medium was water, the concrete's relative dynamic elastic modulus and relative durability index were 9.6% and 75.3% higher, respectively, for concrete cured in 20 °C-95% RH conditions compared to those cured in 0 °C-50% RH conditions. We propose a comprehensive relative durability index (DFw) by combining the results of two methods of freeze-thaw tests. The DFw of concrete cured in 0 °C-50% RH conditions was 83.8% lower than that of concrete cured in 20 °C-95% RH conditions when exposed to a freeze-thaw medium of 5% mass fraction NaCl solution. To evaluate the salt freeze-thaw resistance of concrete pavement, it is recommended to use surface scaling and DFw together.

Comparison of evaluation methods for improving the usability of a Spanish mHealth tool.

OBJECTIVE: Mobile health (mHealth) technology is now widely used across health conditions and populations. The rigorous development of these tools has yielded improved health outcomes, yet the ideal approach for developing mHealth tools continues to evolve, indicating the need for rigorous usability evaluation methods. This study compares two usability evaluation methods - cognitive interviews and usability assessments employing a think-aloud approach - for adapting an evidence-based mHealth tool from English into Spanish. METHODS: We conducted cognitive interviews and usability assessments using a think-aloud protocol to evaluate the usability of an HIV mHealth application among 40 Spanish-speaking adults with HIV in New York City, NY, and La Romana, Dominican Republic. The Health IT Usability Evaluation Model (Health-ITUEM) was used to guide the analysis of qualitative data collected from each method. RESULTS: Participants (N = 40) averaged 43 years old (SD = 12.26; range 20-79), identified primarily Hispanic/Latino (92.5 %), and resided in La Romana (50 %) or New York City (50 %). Both usability evaluation methods yielded similar findings, highlighting learnability and information needs as crucial components of participant feedback for the mHealth application. Cognitive interviews captured participants' perspectives on the app's interface and design. On the other hand, results from usability assessments offered insights into participants' competency while interacting with the mHealth tool. CONCLUSION: Findings from this study highlight the contributions and limitations of including cognitive interviews and task-based usability assessments using a think-aloud approach in mHealth usability testing. Future research should employ a multi-method approach, incorporating complementary usability evaluation methods and engaging participants in multiple assessments. Using complementary usability evaluation methods may provide a more comprehensive understanding of the usability and participant experience aspects of a mHealth tool compared to using a single usability evaluation method.

Exploration of Evaluation Practices in Social Prescribing Services in Ireland: A Cross-Sectional Observational Study.

National health services in Ireland and the UK fund the majority of social prescribing services and have issued recommendations for evaluation. However, it is not known what outcomes are prioritised for evaluation within individual services and what evaluation methods are used to capture recommended outcomes. A survey was carried out to examine evaluation practices of social prescribing services on the island of Ireland. This study used a cross-sectional observational design. The sample was all the staff involved in delivering and/or managing SP services on the island of Ireland. Questionnaires were distributed at a national SP conference and online. Closed-response questions were analysed using descriptive statistics. Content analysis was used for open-ended questions. Eighty-four usable surveys were returned (50% from the Republic of Ireland and 50% from Northern Ireland). All respondents (100%) agreed on the importance of measuring SP outcomes. The most frequently measured outcomes were health and well-being (89.2%) and loneliness (84%). The least frequently measured outcome was the satisfaction of healthcare professionals referring to SP: 78.4% of respondents never measured this outcome. The most frequently used measurement tool was the Short Warwick Edinburgh Mental Well-Being Scale, with 38/76 (50%) respondents using this measure. There was a lack of standardised measures identified for some outcomes. For example, 70% of respondents reported always measuring physical activity (PA), but only four respondents identified a specific PA measure. In open-ended questions, respondents recommended flexibility in evaluation methods to reflect the complexity and individualised focus of SP. They also identified the need for protected time to complete evaluations and recommended a national strategy to inform priorities in evaluations. This study demonstrates a wide variation on the island of Ireland on how SP services are measuring outcomes, with many outcomes rarely or never measured using standardised measures. Agreement is needed on a core outcome set for social prescribing in order to guide service delivery and evaluations.

Measuring digital intervention user experience with a novel ecological momentary assessment (EMA) method, CORTO.

Digital interventions often suffer from low usage, which may reflect insufficient attention to user experience. Moreover, the existing evaluation methods have limited applicability in the remote study of user experience of complex interventions that have expansive content and that are used over an extensive period of time. To alleviate these challenges, we describe here a novel qualitative Ecological Momentary Assessment (EMA) method: the CORTO method (Contextual, One-item, Repeated, Timely, Open-ended). We used it to gather digital intervention user experience data from Finnish adults (n = 184) who lived with interview-confirmed major depressive disorder (MDD) and took part in a randomized controlled trial (RCT) that studied the efficacy of a novel 12-week game-based digital intervention for depression. A second dataset on user experience was gathered with retrospective interviews (n = 22). We inductively coded the CORTO method and retrospective interview data, which led to four user experience categories: (1) contextual use, (2) interaction-elicited emotional experience, (3) usability, and (4) technical issues. Then, we used the created user experience categories and Template Analysis to analyze both datasets together, and reported the results qualitatively. Finally, we compared the two datasets with each other. We found that the data generated with the CORTO method offered more insights into usability and technical categories than the interview data that particularly illustrated the contextual use. The emotional valence of the interview data was more positive compared with the CORTO data. Both the CORTO and interview data detected 55 % of the micro-level categories; 20 % of micro-level categories were only detected by the CORTO data and 25 % only by the interview data. We found that the during-intervention user experience measurement with the CORTO method can provide intervention-specific insights, and thereby further the iterative user-centered intervention development. Overall, these findings highlight the impact of evaluation methods on the categories and qualities of insights acquired in intervention research.

Can self-assessment ability predict student performance in a dental anatomy course?

INTRODUCTION: The development of early self-assessment skills and determining its correlation with academic performance could provide evidence to alter dental curricula. The aim of this retrospective study was to examine the relationships between students' early self-assessment ability in waxing and three different evaluation methods (waxing assessment, written examinations, and tooth identification examination) in a dental anatomy course. MATERIALS AND METHODS: The dental anatomy scores during the academic years of 2018-2019 and 2019-2020 from two cohorts of second-year pre-doctoral dental students at the Harvard School of Dental Medicine were analyzed. Regression analyses were completed to assess the relationship between all evaluation methods. RESULTS: There was a statistically significant correlation between self-assessment ability and the waxing assessment but no significant correlation between self-assessment ability and the other evaluation methods. CONCLUSION: Our results showed that the introduction of self-assessments in dental anatomy waxing was correlated with successful waxing skills. Furthermore, a relevant finding is that students who received higher classifications were also capable of doing better self-assessments. These findings provide evidence that impacts dental curricula.

Evidence-Based Dampness-Heat ZHENG (Syndrome) in Cancer: Current Progress toward Establishing Relevant Animal Model with Pancreatic Tumor / 中国结合医学杂志

Cancer is one of the deadliest diseases affecting the health of human beings. With limited therapeutic options available, complementary and alternative medicine has been widely adopted in cancer management and is increasingly becoming accepted by both patients and healthcare workers alike. Chinese medicine characterized by its unique diagnostic and treatment system is the most widely applied complementary and alternative medicine. It emphasizes symptoms and ZHENG (syndrome)-based treatment combined with contemporary disease diagnosis and further stratifies patients into individualized medicine subgroups. As a representative cancer with the highest degree of malignancy, pancreatic cancer is traditionally classified into the "amassment and accumulation". Emerging perspectives define the core pathogenesis of pancreatic cancer as "dampness-heat" and the respective treatment "clearing heat and resolving dampness" has been demonstrated to prolong survival in pancreatic cancer patients, as has been observed in many other cancers. This clinical advantage encourages an exploration of the essence of dampness-heat ZHENG (DHZ) in cancer and investigation into underlying mechanisms of action of herbal formulations against dampness-heat. However, at present, there is a lack of understanding of the molecular characteristics of DHZ in cancer and no standardized and widely accepted animal model to study this core syndrome in vivo. The shortage of animal models limits the ability to uncover the antitumor mechanisms of herbal medicines and to assess the safety profile of the natural products derived from them. This review summarizes the current research on DHZ in cancer in terms of the clinical aspects, molecular landscape, and animal models. This study aims to provide comprehensive insight that can be used for the establishment of a future standardized ZHENG-based cancer animal model.

[Introduction and Reflection on Novel Medical Device Regulatory Science Tool MDDT].

In recent years, emerging technology medical devices have developed rapidly. How to more scientifically and more efficiently regulate these novel medical devices so as to improve access to advanced medical technology while ensuring safety and effectiveness is a new challenge faced by regulatory authorities, and is also the core topic of regulatory science. New tools, new standards and new methods are important means to achieve regulatory science. "Medical Device Development Tool" proposed by the U.S. FDA is a novel medical device regulatory science tool, which can help medical device developers to predict and evaluate product performance more efficiently. It is also helpful for regulatory authorities to make regulatory decisions more efficiently. This study introduces the concept, qualification process, role of MDDT in medical device regulation and MDDT examples, and makes some discussion on the device evaluation from the perspective of reliability and validity. MDDT can facilitate the developing of novel medical device.

The Bioavailability of Drugs-The Current State of Knowledge.

Drug bioavailability is a crucial aspect of pharmacology, affecting the effectiveness of drug therapy. Understanding how drugs are absorbed, distributed, metabolized, and eliminated in patients' bodies is essential to ensure proper and safe treatment. This publication aims to highlight the relevance of drug bioavailability research and its importance in therapy. In addition to biochemical activity, bioavailability also plays a critical role in achieving the desired therapeutic effects. This may seem obvious, but it is worth noting that a drug can only produce the expected effect if the proper level of concentration can be achieved at the desired point in a patient's body. Given the differences between patients, drug dosages, and administration forms, understanding and controlling bioavailability has become a priority in pharmacology. This publication discusses the basic concepts of bioavailability and the factors affecting it. We also looked at various methods of assessing bioavailability, both in the laboratory and in the clinic. Notably, the introduction of new technologies and tools in this field is vital to achieve advances in drug bioavailability research. This publication also discusses cases of drugs with poorly described bioavailability, providing a deeper understanding of the complex challenges they pose to medical researchers and practitioners. Simultaneously, the article focuses on the perspectives and trends that may shape the future of research regarding bioavailability, which is crucial to the development of modern pharmacology and drug therapy. In this context, the publication offers an essential, meaningful contribution toward understanding and highlighting bioavailability's role in reliable patient treatment. The text also identifies areas that require further research and exploration.

[Advances in methodologies for evaluating cell-mediated immune responses].

Cell-mediated immune response is an important part of machinery in maintaining the body's homeostasis. After the innate immune system selectively activates the adaptive immune system, the cell-mediated immunity exerts its killing and clearance functions. Therefore, evaluating the level of cell-mediated immune response is crucial in the diagnosis and treatment of cancer, monitoring the immune status after organ transplantation, diagnosing and preventing viral diseases, and evaluating the effectiveness of vaccines and other areas. From the initial overall assessment of the immune effects in vivo to the precise detection of the number and function of multiple immune cells, the evaluation methods of cell-mediated immune response have greatly advanced. However, cell-mediated immune response involves multiple levels in the body, and it's difficult to choose the numerous detection methods available. The article systematically compares the evaluation methods of cell-mediated immune response at four different levels: the organism, the tissue and organ, the immune cells and the immune molecules, with the aim to facilitate the applications of related technologies.

Implementation of Overdose Prevention in Maryland: Implications for Resource Allocation, Program Scale-Up, and Evaluation.

Overdose mortality in the United States continues to climb, with Maryland being one of the hardest hit states. We summarized implementation of overdose prevention and response programs in Maryland and identified associations between opioid overdose deaths by jurisdiction in 2019 and implementation of overdose programs by 2021. Data on program implementation are from Maryland's Opioid Operational Command Center (OOCC) Program Inventory. OOCC coordinates the state's response to overdose, and their Program Inventory tracks implementation of 145 programs across 12 domains (e.g., public health, education, and judiciary), including 10 programs designed to broaden naloxone access. The level of program implementation was dichotomized as substantial implementation versus other levels (i.e., partial, planned, and none). We estimated associations between per capita opioid overdose deaths and substantial implementation of: all 145 programs in the Inventory, programs within each of 12 domains, and 10 naloxone programs. Data on program implementation and overdose mortality are summarized at the jurisdiction level. Across jurisdictions, the median proportion of programs with substantial implementation was 51% across all programs and 70% among naloxone programs. Overdose mortality was associated with subsequent substantial implementation of programs within the public health domain (p = .04), but not in the other 11 domains. We did not find evidence that per capita overdose deaths in 2019 spurred overdose program implementation by 2021, with the exception of public health programs. The OOCC Program Inventory is a novel way to track implementation across jurisdictions. Findings can inform the implementation and evaluation of overdose programs in other jurisdictions across the United States.

[Research progress on evaluation methods for head-neck nail position in femoral intertrochanteric fractures].

Objective: To summarize the research progress on the evaluation methods of head-neck nail positions in femoral intertrochanteric fractures. Methods: The literature about the evaluation methods of head-neck nail positions for femoral intertrochanteric fractures in recent years was extensively reviewed, and research progress in the aspects of evaluation methods, clinical applications, and limitations were summarized. Results: The position of head-neck nails in femoral intertrochanteric fractures is closely related to postoperative complications of head-neck nail cutting. Currently, the tip-apex distance (TAD) and femoral head zoning are widely used to evaluate the position of head-neck nails. The main opinion in the literature is that the use of TAD and femoral head zoning can effectively reduce the incidence of head-neck nails cutting. Parker's ratio, as one of the evaluation methods, has been controversial in subsequent studies and has not been widely used in clinical practice. The TAD as referenced to the calcar (CalTAD), which was modified based on TAD, has been gradually accepted by the clinic, but whether it is better than the TAD has not yet been conclusively determined. In recent years, new evaluation methods have been proposed to supplement the previous evaluation methods, such as the tip-neck distance ratio (TNDR) and the standardized TAD (STAD) to avoid the limitations of the TAD and the CalTAD by the volume of the femoral head, and the axis-blade angle (ABA) to supplement the direction of the head-neck nails channel, but at present the clinical application is relatively underutilized, and the validity of the method needs to be further verified. Conclusion: Currently, there are many methods for evaluating the position of head-neck nails in femoral intertrochanteric fractures, TAD<25 mm combined with head-neck nails placed in the middle-middle quadrant or lower-middle quadrant of the femoral head division is currently a highly recognized assessment in the literature, but the optimal assessment is still controversial, and further research needs to be studied.

Quality evaluation methods of chinese medicine based on scientific supervision: recent research progress and prospects.

Traditional Chinese medicine (TCM) is increasingly getting attention worldwide, as it has played a very satisfactory role in treating COVID-19 during these past 3 years, and the Chinese government highly supports the development of TCM. The therapeutical theory and efficacies of Chinese medicine (CM) involve the safety, effectiveness and quality evaluation of CM, which requires a standard sound system. Constructing a scientific and reasonable CM quality and safety evaluation system, and establishing high-quality standards are the key cores to promote the high-quality development of CM. Through the traditional quality control methods of CM, the progress of the Q-marker research and development system proposed in recent years, this paper integrated the research ideas and methods of CM quality control and identified effective quality parameters. In addition, we also applied these effective quality parameters to create a new and supervision model for the quality control of CM. In conclusion, this review summarizes the methods and standards of quality control research used in recent years, and provides references to the quality control of CM and how researchers conduct quality control experiments.
