Abstract
On the basis of retaining the technical identification system of medical negligence, the Medical Association Identification Rules of Medical Damage mainly provides technical services for various types of conciliation work about doctor-patient dispute. Its identification work is still influenced by the thinking of medical negligence technical identification and has certain administrative color. Guidance for Judicial Expertise of Medical Malpractice is mainly reflected that the trial of civil cases and pre-trial mediation of courts need service. Its procedures and evidence review are strictly required by the litigation rules and has the characteristics of public legal services provided as a third-party neutral institution. Technical identification of medical damage, whether organized by the Medical Association or the forensic identification institutions, is carried out under the background of the current Regulations on the Prevention and Treatment of Medical Disputes and the Civil Code of the People's Republic of China; both have a corresponding positive role in regulating the medical damage identification activities, and have also laid a certain foundation for the establishment of a unified identification system in the future in China. To understand the different characteristics of the medical damage identification rules issued by the Chinese Medical Association and the Ministry of Justice, and to improve the understanding of the standardization of the forensic identification of medical damage, a comparative study was conducted on Medical Association Identification Rules of Medical Damage and Guidance for Judicial Expertise of Medical Malpractice from seven aspects: Concept and legal status, entrust of identification, identification acceptance, identification procedures, identification presentation meeting, theory of medical malpractice evaluation, consequences and causality of medical damage. The subject of evaluation, the function of evidence review, the role of consulting experts, the technical standard system of malpractice evaluation and other contents were emphatically analyzed.

Abstract
The present study counted the frequency of detection technologies and monitoring frequency of pesticide species by frequency analysis based on the 28 258 pieces of data on pesticide content of Chinese medicinal materials in CNKI, calculated the detection rate and exceeding rate of different types of pesticides, and systematically analyzed the pesticide residue pollution of Chinese medicinal materials. The results showed that there were 40 types of pesticides with detection rates higher than 10%, where new pesticides such as organochlorines and nicotine accounted for 55%, and organic phosphorus, pyrethroids, and carbamates accounted for 17.5%, 15.0%, and 12.5%, respectively. Seventeen types of pesticides exceeded the standard to varying degrees, including 12 types(70.59%) with exceeding rates not higher than 5%, four types(23.53%) with exceeding rates in the range of 5%-10%, and one type(5.88%) with an exceeding rate higher than 10%. As revealed by the analysis results of the past five years, the pesticide residue pollution of Chinese medicinal materials showed a downward trend. Compared with the conditions at worst, organochlorines decreased by about 2/3 in detection rate and 47.23% in exceeding rate, carbamates by about 1/2 in detection rate and 10.78% in exceeding rate, organic phosphorus by 3/4 in detection rate and 7.22% in exceeding rate, pyrethroids by 1/2 in detection rate and 11.05% in exceeding rate, and other types by about 1/2 in detection rate but not exceeded the standard. In general, pesticide residues in Chinese medicinal materials and safety have been significantly improved. However, pesticide residues are still important factors affecting the quality and safety of Chinese medicinal materials. It is suggested to further improve the control standards of pesticide residues in Chinese medicinal materials, strengthen the monitoring of pesticides used in practical production, and promote the ecological planting mode to facilitate the high-quality development of the Chinese medicinal material industry.

Abstract
Lonicera Japonica Flos is the dried bud or nascent flower of Lonicera japonica(Caprifoliaceae). The plant suffers from various diseases and pests in the growth period and thus pesticides are often used. As a result, the resultant pesticide residues in Lonicera Japonica Flos have aroused great concern. This review summarized the investigation, detection methods, content analysis, and risk assessment of pesticide residues in Lonicera Japonica Flos since 1996, and compared the maximum residue limits among different countries and regions. The results showed that the pesticide residues were detected in Lonicera Japonica Flos from different production areas, and only some exceeded the limits. The residual pesticides have changed from organochlorines to new types such as tebuconazole and nitenpyram. The detection method has upgraded from chromatography to chromatography-mass spectrometry. Most pesticide residues will not cause health risks, except carbofuran. Pesticide residues limit the development of Lonicera Japonica Flos industry in China. In practice, we should improve the drug registration of Lonicera Japonica Flos, promote ecological prevention and control technology, and formulate and promote pesticide residue limit standard of Lonicera Japonica Flos.

Abstract
Panacis Quinquefolii Radix is the dry root of Panax quinquefolium, which is a perennial plant of Araliaceae. The plant has a long growth cycle and serious growth barrier problem, which leads to the use of pesticides. As a result, the pesticide residues in Panacis Quinquefolii Radix are arousing great concern. This paper reviews the research findings on the investigation, detection methods, content analysis and risk assessment of pesticide residues in Panacis Quinquefolii Radix since 1993, and compares the pesticide residue limit standards of different countries and regions. The pesticide residues in Panacis Quinquefolii Radix have been changing from organochlorines with high toxicity to triazines and triazoles with low toxicity. The pesticide residues are generally low, while the pollution of pentachloronitrobenzene and other pesticides still exist. The detection method has evolved from chromatography to chromatography-mass spectrometry. There are no reports of health risks caused by pesticide residues of Panacis Quinquefolii Radix. Pesticide residue is a major factor restricting the sound development of Panacis Quinquefolii Radix industry in China. Therefore, we suggest to improve the registration of pesticides applied to the plant, popularize mature ecological planting mode and supporting technology, and strengthen the research on the risk assessment and limit standard of pesticide residue in Panacis Quinquefolii Radix.

Abstract
Panax notoginseng is a perennial Chinese medicinal plant, which has serious continuous cropping obstacles and is prone to a variety of diseases and insect pests during the growth process. At present, the prevention and control of pests and diseases is mainly carried out through chemical pesticides, and the consequent pesticide residues of P. notoginseng have attracted much attention. This study reviewed the types and detection methods of pesticide residues in P. notoginseng from 1981 to 2021, and compared the limits of pesticide residues in P. notoginseng in China and abroad to provide a reference for rational application of pesticides in P. notoginseng and quality control of medicinal materials, thereby promoting the sustainable development of the P. notoginseng industry in China. Currently, there are only 40 published papers on pesticide residues of P. notoginseng, which is indicative of a serious problem of insufficient research. At present, hundreds of pesticide residues in P. notoginseng can be detected simultaneously by using chromatography-tandem mass spectrometry. The pesticides detected have gradually changed from early prohibited ones, such as dichlorodiphenyl trichloroethane(DDT), benzene hexachloride(BHC), and parathion, to low toxic ones(e.g., dimethomorph, procymidone, propicona-zole, and difenoconazole). The dietary risk from pesticide residues in P. notoginseng is low, which would not cause harm to consu-mers. This study concluded that in the future, the development of the quality standard for pesticide residues of P. notoginseng should be actively carried out. To increase the pesticides used in actual production in the quality standard based on the existing ones and to guide farmers to use pesticides scientifically will be the focus of future work.

Abstract
The demand for Angelicae Sinensis Radix, the dry root of Angelica sinensis, has been increasing year by year. However, the continuous cropping obstacles, frequent occurrence of pests and diseases, overuse of chemical pesticides, excessive pesticide residues and other problems in Angelicae Sinensis Radix production have attracted much attention. In this paper, we summarized the common diseases and pests attacking Angelica sinensis as well as the detection methods and characteristics of pesticide residues in Angelicae Sinensis Radix from 2002 to 2021. Additionally, we compared the limit standards of pesticide residues in Angelicae Sinensis Radix in and out of China and put forward suggestions for the high-quality and green development of Angelicae Sinensis Radix industry conside-ring the existing problems. The pesticide residues in Angelicae Sinensis Radix have been changing from organochlorines to organophosphorus pesticides. In recent years, some organophosphorus pesticides such as phorate, phoxim, isofenphos-methyl, phorate-sulfoxide, fenamiphos, isocarbophos, omethoate, and triazophos in Angelicae Sinensis Radix have seriously exceeded the standards. The detection methods of pesticide residues has evolved from chromatography to high performance chromatography-mass spectrometry, gas chromatography-mass spectrometry(GC-MS), and liquid chromatography-mass spectrometry(LC-MS), and some new detection techniques such as immunoassay have also been applied. Pesticide residues have become a primary factor that restricting the development of Angelicae Sinensis Radix industry. Therefore, moderate application of pesticides, establishment of ecological planting system, and strict limit standards of pesticide residues are necessary to solve the pesticide residue problem.

Abstract
The last common ancestor of birds and crocodylians plus all of its descendants (clade Archosauria) dominated terrestrial Mesozoic ecosystems, giving rise to disparate body plans, sizes, and modes of locomotion. As in the fields of vertebrate morphology and paleontology more generally, studies of archosaur skeletal structure have come to depend on tools for acquiring, measuring, and exploring three‐dimensional (3‐D) digital models. Such models, in turn, form the basis for many analyses of musculoskeletal function. A set of shared conventions for describing 3‐D pose (joint or limb configuration) and 3‐D kinematics (change in pose through time) is essential for fostering comparison of posture/movement among such varied species, as well as for maximizing communication among scientists. Following researchers in human biomechanics, we propose a standard methodological approach for measuring the relative position and orientation of the major segments of the archosaur pelvis and hindlimb in 3‐D. We describe the construction of anatomical and joint coordinate systems using the extant guineafowl and alligator as examples. Our new standards are then applied to three extinct taxa sampled from the wider range of morphological, postural, and kinematic variation that has arisen across >250 million years of archosaur evolution. These proposed conventions, and the founding principles upon which they are based, can also serve as starting points for measuring poses between elements within a hindlimb segment, for establishing coordinate systems in the forelimb and axial skeleton, or for applying our archosaurian system more broadly to different vertebrate clades.

Abstract
To learn the current situation and strengthen the management of national standards for Chinese medicinal materials, we sorted out the relevant national standards. According to incomplete statistics, there are 1 185 kinds of Chinese medicinal materials, including 1 024 kinds of plant medicines, 106 kinds of animal medicines, and 54 kinds of mineral medicines, in addition to ethnic medicinal materials with different functions. The relevant standards include 819 Pharmacopoeia standards, 342 standards issued by the Ministry of Health or National Medicinal Products Administration, 7 standards for new medicinal materials, and 17 standards for imported medicinal materials. In this paper, the sources of standards as well as the distribution of families and genera and the distribution of medicinal parts of medicinal materials are analyzed. The suggestions are as follows:(1)to improve the coordination among different national standards of Chinese medicinal materials;(2)to improve the standardization and controllability of relevant standards;(3)to revise the issued standards for Chinese medicinal materials(including Tibetan, Uygur, and Mongolian medicinal materials).

Abstract
Human biomedical datasets that are critical for research and clinical studies to benefit human health also often contain sensitive or potentially identifying information of individual participants. Thus, care must be taken when they are processed and made available to comply with ethical and regulatory frameworks and informed consent data conditions. To enable and streamline data access for these biomedical datasets, the Global Alliance for Genomics and Health (GA4GH) Data Use and Researcher Identities (DURI) work stream developed and approved the Data Use Ontology (DUO) standard. DUO is a hierarchical vocabulary of human and machine-readable data use terms that consistently and unambiguously represents a dataset's allowable data uses. DUO has been implemented by major international stakeholders such as the Broad and Sanger Institutes and is currently used in annotation of over 200,000 datasets worldwide. Using DUO in data management and access facilitates researchers' discovery and access of relevant datasets. DUO annotations increase the FAIRness of datasets and support data linkages using common data use profiles when integrating the data for secondary analyses. DUO is implemented in the Web Ontology Language (OWL) and, to increase community awareness and engagement, hosted in an open, centralized GitHub repository. DUO, together with the GA4GH Passport standard, offers a new, efficient, and streamlined data authorization and access framework that has enabled increased sharing of biomedical datasets worldwide.

Abstract
The Global Alliance for Genomics and Health (GA4GH) supports international standards that enable a federated data sharing model for the research community while respecting data security, ethical and regulatory frameworks, and data authorization and access processes for sensitive data. The GA4GH Passport standard (Passport) defines a machine-readable digital identity that conveys roles and data access permissions (called "visas") for individual users. Visas are issued by data stewards, including data access committees (DACs) working with public databases, the entities responsible for the quality, integrity, and access arrangements for the datasets in the management of human biomedical data. Passports streamline management of data access rights across data systems by using visas that present a data user's digital identity and permissions across organizations, tools, environments, and services. We describe real-world implementations of the GA4GH Passport standard in use cases from ELIXIR Europe, National Institutes of Health, and the Autism Sharing Initiative. These implementations demonstrate that the Passport standard has provided transparent mechanisms for establishing permissions and authorizing data access across platforms.

Abstract
Stem cells, which could be developed as starting or raw materials for cell therapy, hold tremendous promise for regenerative medicine. However, despite multiple fundamental and clinical studies, clinical translation of stem cells remains in the early stages. In contrast to traditional chemical drugs, cellular products are complex, and efficacy can be altered by culture conditions, suboptimal cell culture techniques, and prolonged passage such that translation of stem cells from bench to bedside involves not only scientific exploration but also normative issues. Establishing an integrated system of standards to support stem cell applications has great significance in efficient clinical translation. In recent years, regulators and the scientific community have recognized gaps in standardization and have begun to develop standards to support stem cell research and clinical translation. Here, we discuss the development of these standards, which support the translation of stem cell products into clinical therapy, and explore ongoing work to define current stem cell guidelines and standards. We also introduce general aspects of stem cell therapy and current international consensus on human pluripotent stem cells, discuss standardization of clinical-grade stem cells, and propose a framework for establishing stem cell standards. Finally, we review ongoing development of international and Chinese standards supporting stem cell therapy.

Requirements for human cardiomyocytes. Cell Prolif 2021; 55:e13150. [PMID: 34708452 PMCID: PMC9055907 DOI: 10.1111/cpr.13150] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 10/06/2021] [Accepted: 10/09/2021] [Indexed: 11/29/2022] Open
Abstract
‘Requirements for human cardiomyocytes', jointly drafted and agreed upon by experts from the Chinese Society for Stem Cell Research, is the first guideline for human cardiomyocytes in China. This standard specifies the technical requirements, test methods, test regulations, instructions for use, labelling requirements, packing requirements, storage requirements, transportation requirements and waste disposal requirements for human cardiomyocytes, which is designed to normalize and standardize human cardiomyocyte research and production. It was originally released by the China Society for Cell Biology on 9 January 2021. We hope that the publication of this guideline will promote institutional establishment, acceptance and execution of proper protocols, and accelerate the international standardization of human cardiomyocytes for applications.

The beneficial effect of Escalated-R-CHOP-21 for the treatment of diffuse large B-cell lymphoma in elderly male patients: A propensity-matched cohort study. Cancer Med 2021; 10:7650-7664. [PMID: 34581023 PMCID: PMC8559475 DOI: 10.1002/cam4.4296] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 08/09/2021] [Accepted: 09/07/2021] [Indexed: 12/18/2022] Open
Abstract
PURPOSE Some studies have indicated that using 500 mg/m2 rituximab combined with CHOP-14 may be beneficial for elderly men but not women with diffuse large B-cell lymphoma (DLBCL). The purpose of this study was to investigate the potential benefit of escalated doses of rituximab with CHOP-21 as the first-line treatment in male patients with DLBCL. METHODS We performed a retrospective cohort study to analyze the survival benefit of rituximab 500 mg/m2 plus the CHOP-21 regimen (Escalated-R-CHOP-21) as the first-line treatment compared with using rituximab 375 mg/m2 plus the CHOP-21 regimen (Standard-R-CHOP-21) in men with DLBCL. We used propensity score matching to maximize the balance of the observed covariables. The primary endpoints of this study were the progression-free survival (PFS) rate and overall survival (OS) rate at 3 years. RESULTS After a median follow-up of 47 months (IQR 31-65), no significant difference in PFS and OS was found for men treated with Escalated-R-CHOP-21 compared with Standard-R-CHOP-21 [3-year PFS: 69.7% versus 71.9%, p = 0.867; 3-year OS: 83.0% versus 82.4%, p = 0.660]. After 1:1 propensity score matching, we found that the patients using Escalated-R-CHOP-21 had statistically significant survival benefits relative to Standard-R-CHOP-21 among the 96 matched elderly male patients for 3-year PFS [75.5% (95% CI 62.8-88.2) versus 58.2% (95% CI 44.3-72.1); p = 0.019] and 3-year OS [86.6% (95% CI 76.4-96.8) versus 65.8% (95% CI 52.1-79.5); p = 0.017]. However, no differences in survival were observed for younger male patients. Furthermore, the dose effect in PFS of Escalated-R-CHOP-21 was more obvious for elderly male patients with no high-risk extranodal sites (p = 0.005 and interaction p = 0.030). CONCLUSION Escalated-R-CHOP-21 could be a safe and effective option for treating elderly male patients with DLBCL. This study provides new insight into optimizing the standard treatment regimen, which may have important therapeutic implications in elderly male patients with DLBCL.

Abstract
Although COVID-19 vaccines are becoming increasingly available, their ability to effectively control and contain the spread of the COVID-19 pandemic is highly contingent on an array of factors. This paper discusses how limitations to vaccine accessibility, issues associated with vaccine side effects, concerns regarding vaccine efficacy, along with the persistent prevalence of vaccine hesitancy among the public, including health care professionals, might impact the potential of COVID-19 vaccines to curb the pandemic. We draw insights from the literature to identify practical solutions that could boost people’s adoption of COVID-19 vaccines and their accessibility. We conclude with a discussion on health experts’ and government officials’ moral and ethical responsibilities to the public, even in light of the urgency to adopt and endorse “the greatest amount of good for the greatest number” utilitarian philosophy in controlling and managing the spread of COVID-19.

Abstract
Salmonella enterica serovars are associated with numerous annual deaths worldwide and are responsible for a large number of foodborne diseases. Within this frame of reference, knowledge of antimicrobial susceptibility represents the fundamental approach of most Salmonella treatments. Therefore, scientific publications of antimicrobial susceptibilities and resistance must be precise, with interpretations adjusted to a particular standard. Hence, the three objectives in this study were: (i) to describe the frequency of antimicrobial-resistant isolates of Non-Typhoidal Salmonella (NTS) isolated from beef, pork, chicken meat, and other meat products; (ii) to describe the distribution of serovars and their multi-resistance to antibiotics for clinical use (veterinary and human) between 1996 and 2019; and (iii) to propose additional considerations that could improve the use and usefulness of the published results. Our results determined that the predominant isolates came from poultry. Enteritidis and Typhimurium were the most reported serovars by MIC (with both having the highest resistance to TET) while the lowest resistance was to CIP and CRO for Enteritidis and Typhimurium, respectively. The multi-resistance pattern AMP AMC CEP GEN KAN STR TET was the most frequently observed pattern by MIC in Montevideo and Seftenberg, while, for disc diffusion, the pattern AMP STR TET was the most frequent in the Bredeney serotype. In conclusion, researchers should carry out homogeneous sampling procedures, identify the types of the samples, use standard identification methods, and employ appropriate standards for antimicrobial susceptibility interpretation. Additionally, there is also a need for all WHO members to comply with the WHA 73.5 resolution. Our final recommendation is for all producers to reduce antibiotic prophylactic use.

Abstract
HiGHmed is a German Consortium where eight University Hospitals have agreed to the cross-institutional data exchange through novel medical informatics solutions. The HiGHmed Use Case Infection Control group has modelled a set of infection-related data in the openEHR format. In order to establish interoperability with the other German Consortia belonging to the same national initiative, we mapped the openEHR information to the Fast Healthcare Interoperability Resources (FHIR) format recommended within the initiative. FHIR enables fast exchange of data thanks to the discrete and independent data elements into which information is organized. Furthermore, to explore the possibility of maximizing analysis capabilities for our data set, we subsequently mapped the FHIR elements to the Observational Medical Outcomes Partnership Common Data Model (OMOP CDM). The OMOP data model is designed to support the conduct of research to identify and evaluate associations between interventions and outcomes caused by these interventions. Mapping across standard allows to exploit their peculiarities while establishing and/or maintaining interoperability. This article provides an overview of our experience in mapping infection control related data across three different standards openEHR, FHIR and OMOP CDM.

Abstract
Infectious diseases due to microbial resistance pose a worldwide threat that calls for data sharing and the rapid reuse of medical data from health care to research. The integration of pathogen-related data from different hospitals can yield intelligent infection control systems that detect potentially dangerous germs as early as possible. Within the use case Infection Control of the German HiGHmed Project, eight university hospitals have agreed to share their data to enable analysis of various data sources. Data sharing among different hospitals requires interoperability standards that define the structure and the terminology of the information to be exchanged. This article presents the work performed at the University Hospital Charité and Berlin Institute of Health towards a standard model to exchange microbiology data. Fast Healthcare Interoperability Resources (FHIR) is a standard for fast information exchange that allows to model healthcare information, based on information packets called resources, which can be customized into so-called profiles to match use case- specific needs. We show how we created the specific profiles for microbiology data. The model was implemented using FHIR for the structure definition, and the international standards SNOMED CT and LOINC for the terminology services.

Abstract
The popularity of the Power Line Communication (PLC) system has decreased due to significant deficiencies in the technology itself, even though new wire installation is not required. In particular, regarding the request for high-speed throughput to fulfill smart-grid requirements, Broadband Power Line (BPLC) can be considered. This paper approaches PLC technology as an object of simulation experimentation in the Broadband Power Line Communication (BPLC) area. Several experimental measurements in a real environment are also given. This paper demonstrates these experimental simulation results as potential mechanisms for creating a complex simulation tool for various PLC technologies focusing on communication with end devices such as sensors and meters. The aim is to demonstrate the potential and limits of BPLC technology for implementation in Smart Grids or Smart Metering applications.

Abstract
OBJECTIVE The purpose of this study was to identify the challenges of Iranian hospital accreditation standards and provide solutions. DESIGN A qualitative research design was used in this study. Open and semi-structured interviews were conducted in 2018. Thematic analysis was used to analyse qualitative data. SETTING Public, private, semi-public, charity and military hospitals in Tehran, Iran. PARTICIPANTS A pluralistic evaluation approach was employed and 151 participants including policy makers, hospital management and staff, accreditation surveyors and university professors participated in this study. RESULTS Challenges of hospital accreditation standards were grouped into two groups: standards development process and standards content. Lack of an independent standards development committee, insufficient expertise of committee members, inconsistencies among the standards' constructs, inappropriate standard classification, ambiguity of standards, unmeasurable standards, vague and inflexible scoring system, and inability to use some standards were the main challenges of Iran hospital accreditation standards. Establishing a scientific committee consisting of representative from hospitals, health insurance companies, professional and scientific associations and universities for standard development, training the committee members, and utilizing hospital's feedback will help address these problems. CONCLUSION Iran's hospital accreditation standards face challenges that prevent them from achieving their goals, that is, improving the quality, safety, effectiveness and efficiency of hospital services. Necessary measures should be taken to solve these problems.
