[Status of outcome measures in randomized controlled trials of kidney-tonifying and blood-activating method in treatment of knee osteoarthritis]

This study assesses the status of outcome measures in the randomized controlled trial(RCT) involving the kidney-tonif-ying and blood-activating method for treating knee osteoarthritis(KOA), aiming to establish a theoretical foundation for the development of a core set of outcome measures in traditional Chinese medicine(TCM) treatment of KOA. The relevant articles were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science, in addition to ClinicalTrials.gov and the China Clinical Trial Registration Center, with the time interval from inception to August 2023. The RCT of treating KOA with the kidney-tonifying and blood-activating method was included. Two assessors independently conducted literature screening, data collection, and qualitative analysis to compile the outcome measure results. A total of 350 RCTs were included, involving 165 outcome measures with the total frequency of 1 462. These outcome measures were categorized into six domains: symptom and sign measures(23) with the frequency of 718(49.1%), TCM symptom and syndrome measures(3) with the frequency of 53(3.6%), physical examination measures(130) with the frequency of 506(34.6%), quality of life measures(4) with the frequency of 20(1.3%), long-term efficacy measures(2) with the frequency of 6(0.4%), and safety measures(3) with the frequency of 159(10.9%). Additionally, 53 studies used TCM syndrome and symptom scores as indicators of efficacy, employing eight distinct measurement tools. The RCTs involving the kidney-tonifying and blood-activating method for treating KOA had a variety of problems, such as unclear prio-ritization of outcome measures, diversity in measurement tools, absence of standardized assessment criteria for specific measures, and non-standardized usage. These problems affected the research quality and reliability. Hence, it is advisable to draw upon international expertise, improve research design, and merge TCM efficacy characteristics with clinical research to establish a core set of KOA outcome measures aligned with TCM principles.

Antidepressant mechanism of traditional Chinese medicine: Involving regulation of circadian clock genes

Numerous studies have demonstrated an intimate relationship between circadian rhythm disorders and the development and prevention of depression. The biological clock genes, which constitute the molecular basis of endogenous circadian rhythms, hold promising prospects for depression treatment. Based on an extensive review of recent domestic and international research, this article presents a comprehensive analysis of how traditional Chinese medicine (TCM) intervenes in depression by regulating circadian rhythms. The findings indicate that TCM exerts its antidepressant effects by targeting specific biological clock genes such as Bmal1, clock, Arntl, Per1, Per2, Per3, Nr1d1, Cry2, and Dbp, as well as regulating circadian rhythms of hormone secretion. However, most current research is still confined to basic experimental studies, lacking clinical double-blind control trials to further validate these viewpoints. Furthermore, there is insufficient research on the signal transduction pathway between biological clock genes and pathological changes in depression. Additionally, further clarification is needed regarding the specific targets of TCM on the biological clock genes.

Antimicrobial Hydrogels: Potential Materials for Medical Application

Microbial infections based on drug-resistant pathogenic organisms following surgery or trauma and uncontrolled bleeding are the main causes of increased mortality from trauma worldwide. The prevalence of drug-resistant pathogens has led to a significant increase in medical costs and poses a great threat to the normal life of people. This is an important issue in the field of biomedicine, and the emergence of new antimicrobial materials hydrogels holds great promise for solving this problem. Hydrogel is an important material with good biocompatibility, water absorption, oxygen permeability, adhesion, degradation, self-healing, corrosion resistance, and controlled release of drugs as well as structural diversity. Bacteria-disturbing hydrogels have important applications in the direction of surgical treatment, wound dressing, medical device coating, and tissue engineering. This paper reviews the classification of antimicrobial hydrogels, the current status of research, and the potential of antimicrobial hydrogels for one application in biomedicine, and analyzes the current research of hydrogels in biomedical applications from five aspects: metal-loaded hydrogels, drug-loaded hydrogels, carbon-material-loaded hydrogels, hydrogels with fixed antimicrobial activity and biological antimicrobial hydrogels, and provides an outlook on the high antimicrobial activity, biodegradability, biocompatibility, injectability, clinical applicability and future development prospects of hydrogels in this field.

Research Status of Manufacturing Technology of Tungsten Alloy Wire

In light of the fact that tungsten wire is gradually replacing high-carbon steel wire as a diamond cutting line, it is particularly important to study tungsten alloy wire with better strength and performance. According to this paper, in addition to various technological factors (powder preparation, press forming, sintering, rolling, rotary forging, annealing, wire drawing, etc.), the main factors affecting the properties of the tungsten alloy wire are the composition of the tungsten alloy, the shape and size of the powder, etc. Combined with the research results in recent years, this paper summarizes the effects of changing the composition of tungsten materials and improving the processing technology on the microstructure and mechanical properties of tungsten and its alloys and points out the development direction and trend of tungsten and its alloy wires in the future.

Research Progress of Laser Cladding on the Surface of Titanium and Its Alloys

Titanium (Ti) and its alloys have been widely employed in aeronautical, petrochemical, and medical fields owing to their fascinating advantages in terms of their mechanical properties, corrosion resistance, biocompatibility, and so on. However, Ti and its alloys face many challenges, if they work in severe or more complex environments. The surface is always the origin of failure for Ti and its alloys in workpieces, which influences performance degradation and service life. To improve the properties and function, surface modification becomes the common process for Ti and its alloys. The present article reviews the technology and development of laser cladding on Ti and its alloys, according to the cladding technology, cladding materials, and coating function. Generally, the laser cladding parameters and auxiliary technology could influence the temperature distribution and elements diffusion in the molten pool, which basically determines the microstructure and properties. The matrix and reinforced phases play an important role in laser cladding coating, which can increase the hardness, strength, wear resistance, oxidation resistance, corrosion resistance, biocompatibility, and so on. However, the excessive addition of reinforced phases or particles can deteriorate the ductility, and thus the balance between functional properties and basic properties should be considered during the design of the chemical composition of laser cladding coatings. In addition, the interface including the phase interface, layer interface, and substrate interface plays an important role in microstructure stability, thermal stability, chemical stability, and mechanical reliability. Therefore, the substrate state, the chemical composition of the laser cladding coating and substrate, the processing parameters, and the interface comprise the critical factors which influence the microstructure and properties of the laser cladding coating prepared. How to systematically optimize the influencing factors and obtain well-balanced performance are long-term research issues.

[Research status of Bovis Calculus and relevant Chinese patent medicines based on bibliometric analysis]

With scarce resources, natural Bovis Calculus is expensive and hard to meet clinical demand. At the moment, four kinds of Bovis Calculus are available on the market: the natural product, in vitro cultured product, synthesized product, and the product formed in cow after manual intervention. In this study, papers on the four kinds of Bovis Calculus products and relevant Chinese patent medicines were searched from Web of Science, PubMed, and China National Knowledge Infrastructure(CNKI). CiteSpace, citexs AI, and CNKI were employed for bibliometric analysis and knowledge map analysis. On this basis, the status, trend, and focuses of research on Bovis Calculus and relevant Chinese patent medicines were summarized. The results suggested overall slow development in the research on Bovis Calculus and relevant Chinese patent medicines with three typical growth stages. It is consistent with the development of Bovis Calculus substitutes and the national policy for the development of traditional Chinese medicine. At the moment, the research on Bovis Calculus and relevant Chinese patent medicines has been on the rise. In recent years, there has been an explosion of research on them, particularly the quality control of Bovis Calculus and the Chinese patent medicines, the pharmacological efficacy of Chinese patent medicines, such as Angong Niuhuang Pills, and the comparison of the quality of various Bovis Calculus products. However, there is a paucity of research on the pharmacological efficacy and the mechanism of Bovis Calculus. This medicinal and the relevant Chinese patent medicines have been studied from diverse perspectives and China becomes outstanding in this research field. However, it is still necessary to reveal the chemical composition, pharmacological efficacy, and mechanism through multi-dimensional deep research.

[CiteSpace knowledge map analysis of Angong Niuhuang Pills in recent twenty years]

Angong Niuhuang Pills, a classical formula in traditional Chinese medicine, are lauded as one of the "three treasures of febrile diseases" and have been widely used in the treatment of diverse disorders with definite efficacy. However, there is still a lack of bibliometric analysis of research progress and development trend regarding Angong Niuhuang Pills. Research articles on Angong Niuhuang Pills in China and abroad(2000-2022) were retrieved from CNKI and Web of Science. CiteSpace 6.1 was used to visualize the key contents of the research articles. In addition, the research status of Angong Niuhuang Pills was analyzed by information extraction to allow insight into the research trends and hotspots about Angong Niuhuang Pills. A total of 460 Chinese articles and 41 English articles were included. Beijing University of Chinese Medicine and Sun Yat-Sen University were the research institutions that have published the largest amount of research articles in Chinese and English. The keyword analysis showed that the Chinese articles focused on cerebral hemorrhage, stroke, neurological function, coma, cerebral infarction, craniocerebral injury, and clinical application, while the English articles focused on the mechanisms of cerebral ischemia, stroke, heavy metal, blood-brain barrier, and oxidative stress. Stroke, blood-brain barrier, and oxidative stress were presumably the research hotspots in the future. At present, the research on Angong Niuhuang Pills is still in the developing stage. It is necessary to highlight the in-depth research on the active components and mechanism of action and carry out large-scale randomized controlled clinical trials to provide references for the further development and application of Angong Niuhuang Pills.

The Regulatory Mechanism and Research Progress of Ferroptosis in Gastric Cancer

Ferroptosis is a novel cell death modality discovered in recent years that is different from apoptosis and necrosis. It is usually associated with changes in the regulatory signaling in multiple organelles and depends on iron. It is caused by an imbalance between the generation and degradation of intracellular lipid reactive oxygen species (ROS). In addition to increased levels of cytoplasmic ROS and lipids, decreased mitochondrial volume and thickened mitochondrial membranes are markers of ferroptotic death. Gastric cancer is a common malignant tumor, but few studies on the possible role of ferroptosis in gastric cancer have been reported. Although ferroptosis is involved in multifactor-induced carcinogenesis, studies have also shown the role of ferroptosis in the selective killing of tumor cells, thereby inhibiting tumor progression and metastasis. In this paper, the definition, characteristics, and regulatory mechanism of ferroptosis and its potential role in gastric cancer are discussed. Therefore, this review is expected to provide a reference for the treatment of diseases based on ferroptosis and provide a direction for future research on the pathogenesis and development of gastric cancer and the development of anticancer drugs.

It is of great significance to explore the research status, development trend and future research hotspots in the field of COM to promote the development of this field. This study is aimed to explore the global research status of COM and predict its future research hotspots based on bibliometric and visualized analysis.

METHODS

Web of Science core collection database was used to search the related literature of COM from 1994 to 2020. All data were imported into Microsoft Excel 2019 for collation. Additionally, the literature quality of countries, authors, journals, and institutions is evaluated. The VOS viewer software was used for conducting co-analysis, co-citation analysis, and keyword co-occurrence analysis of literature to analyze the global status and predict the future hotspots of the COM field.

RESULTS

A total of 726 articles were retrieved in this study. The number of global publications shows a trend of wave growth, but the increase is not significant. It is expected that the number of COM articles will remain at more than 50 per year in the next decade. The COM literature published in the United States (Publications = 160, H index = 37, average citations per item = 28.63) is of the highest quality. Girschick HJ (Publications = 16, H index = 14, average citations per item = 52.25) is the most contributed scholar in the field of COM. UNIV IOWA (Publications = 15, H index = 11, average citations per item = 57.27) and UNIV WURZBURG (Publications = 18, H index = 15, average citations per item = 47.5) are influential institutions in the field of COM. The results of co-occurrence analysis show that the field of COM can be roughly divided into the following five modules: COM surgical research, COM basic research, COM diagnosis-related research, chronic recurrent multifocal osteomyelitis (CRMO)-related research, risk factors of COM. Risk factors of COM are the module with the highest concentration of hot words.

CONCLUSION

COM-related research will continue to develop further in the next decade. The diagnosis research and risk factors of COM are the most popular research modules in recent years. Some controversial or troubled issues including the efficacy of perforator flap and fascia flap covering soft tissue, searching exclusive detection methods for the diagnosis of COM and bisphosphonates and biological agents in the treatment of CRMO may lead to the development of the COM field.

Electric power wheelchairs (EPWs) enhance the mobility capability of the elderly and the disabled, while the human-machine interaction (HMI) determines how well the human intention will be precisely delivered and how human-machine system cooperation will be efficiently conducted. A bibliometric quantitative analysis of 1154 publications related to this research field, published between 1998 and 2020, was conducted. We identified the development status, contributors, hot topics, and potential future research directions of this field. We believe that the combination of intelligence and humanization of an EPW HMI system based on human-machine collaboration is an emerging trend in EPW HMI methodology research. Particular attention should be paid to evaluating the applicability and benefits of the EPW HMI methodology for the users, as well as how much it contributes to society. This study offers researchers a comprehensive understanding of EPW HMI studies in the past 22 years and latest trends from the evolutionary footprints and forward-thinking insights regarding future research.

[Analysis of research status based on projects in pharmacokinetics of traditional Chinese medicine funded by National Natural Science Foundation of China]

The pharmacokinetics of traditional Chinese medicine is a subject that studies the dynamic changes of the absorption, distribution, metabolism and excretion of complex components of traditional Chinese medicine, which is an important method for elucidating the pharmacodynamic material basis, action characteristics, and compatibility mechanisms of traditional Chinese medicine. However, given on the fact that traditional Chinese medicine is a multi-dimensional and complex system with multiple components, multiple pathways, multiple targets, and an unclear pharmacodynamic material basis, the research on the pharmacokinetics of traditio-nal Chinese medicine has become a scientific and technological problem. Although the pharmacokinetics of traditional Chinese medicine has achieved remarkable development with the emergence of new theories, methods and technologies, there are still some problems in the application of the research direction of the pharmacokinetics of traditional Chinese medicine judging from the current application of the National Natural Science Foundation of China. Therefore, this article discussed the current research status on pharmacokinetics of traditional Chinese medicines by analyzing the projects funded by the National Natural Science Foundation of China in the past 5 years from 2016 to 2020, mainly including the application and funding analysis, main research contents of the projects in pharmacokinetics of traditional Chinese medicines. And the research hotspots, difficulties and deficiencies were focused in order to provide certain reference for researchers engaged in pharmacokinetics of traditional Chinese medicine.

In December 2019, an outbreak of pneumonia, which was named COVID-2019, emerged as a global health crisis. Scientists worldwide are engaged in attempts to elucidate the transmission and pathogenic mechanisms of the causative coronavirus. COVID-19 was declared a pandemic by the World Health Organization in March 2020, making it critical to track and review the state of research on COVID-19 to provide guidance for further investigations. Here, bibliometric and knowledge mapping analyses of studies on COVID-19 were performed, including more than 1,500 papers on COVID-19 available in the PubMed and China National Knowledge Infrastructure databases from January 1, 2020 to March 8, 2020. In this review, we found that because of the rapid response of researchers worldwide, the number of COVID-19-related publications showed a high growth trend in the first 10 days of February; among these, the largest number of studies originated in China, the country most affected by pandemic in its early stages. Our findings revealed that the epidemic situation and data accessibility of different research teams have caused obvious difference in emphases of the publications. Besides, there was an unprecedented level of close cooperation and information sharing within the global scientific community relative to previous coronavirus research. We combed and drew the knowledge map of the SARS-CoV-2 literature, explored early status of research on etiology, pathology, epidemiology, treatment, prevention, and control, and discussed knowledge gaps that remain to be urgently addressed. Future perspectives on treatment, prevention, and control are also presented to provide fundamental references for current and future coronavirus research.

[Research status and development strategies of moxibustion standardization]

Based on the analysis of the present situation of standardization of moxibustion, it is found that the published standards of acupuncture and moxibustion are predominated at acupoint standard and acupuncture manipulation standard. Moxibusiton standardization mainly focuses on the manipulation. It is relatively lack of the standards of moxibustion materials and device. Four suggestions are put forward on the development strategies of moxibustion standardization: 1. Rectify the current situation that more attention paid to acupuncture rather than moxibustion, strengthen the inheritance of traditional experiences and the excavation of ancient literature, expand the indications of moxibustion and confirm the clinical effect of it. 2. Promote the whole process of moxibustion standardization, starting from moxibustion technique to its material, device and manipulation. 3. Enhance the equipment construction of moxibustion, combine with other build engineering disciplines, e.g. artificial intelligence and communication technology, and construct a multi-disciplinary intersection system. 4. Improve the promotion and development mode of moxibustion, propel all-round development of moxibustion in the clinical application, promotion mode and standardization construction, etc.

PURPOSE

There is a need for speech-language pathology (SLP) research in the Philippines, in order to fill in knowledge gaps relevant to the local context. Information about the local SLP research status remains inadequate. This study describes local SLP research done over the almost past four decades.

METHOD

Using a descriptive retrospective design, a search was made for all empirical research articles completed by Filipino SLPs from 1978 to 2015.

RESULT

A total of 250 research articles were identified and described along several parameters. A predominant number were authored by the SLPs in the academe (97.20%). There was a focus on language (27.60%) and the nature of communication/swallowing disorders (20.80%). More than half utilised quantitative exploratory research designs (69.20%). Several used survey forms to generate data (38.41%). Nearly all were unpublished (93.60%) and were unfunded (94.80%).

CONCLUSION

The current study revealed a dearth of research studies, limited diversity of research articles, limited research dissemination and funding concerns. It is suggested that the results of the current study can serve as a reference point to restructure research systems in the Philippines and in other developing countries, and offer data that can be used to develop a research agenda for the profession.
