ABSTRACT
Objective:To explore the application effect of "connections, concepts, concrete practice and conclusions (4C)" teaching method combined with two-way evaluation method in nursing teaching of gastrointestinal surgery, so as to provide reference for personnel training and quality control of practice.Methods:A historical controlled study was conducted to prospectively include the nursing interns received by the Department of Gastrointestinal Surgery of the hospital from May 2020 to May 2022 as the subjects of this study. The interns were divided into the control group (64 interns from May 2020 to May 2021) and the research group (93 interns from June 2021 to May 2022) according to the order of admission of nursing interns. The control group was taught by traditional nursing teaching method, while the research group was taught by "4C" teaching method combined with two-way evaluation method. The scores of theoretical knowledge and operation of nursing students in the two groups were compared after 6 weeks of practice. The self-directed learning ability of nursing students in the two groups was compared before and after 6 weeks of practice [Chinese version of self-rating scale of self-directed learning (SRSSDL)]. The evaluation of teaching quality between two groups of nursing students were compared. SPSS 25.0 was used for t-test and Chi-square test. Results:One person in the control group voluntarily quit the internship, and two in the observation group voluntarily quit the internship. Finally, 63 people in the control group and 91 people in the research group entered the study. There was no statistical significant difference between the two groups in baseline data ( P>0.05). At 6 weeks of practice, the scores of theoretical knowledge (87.96±4.62) and operation (92.60±4.25) in the study group were higher than those in the control group [(86.02±4.53) and (88.27±4.31)] ( P<0.05). At 6 weeks of practice, the total scores of learning awareness, learning behavior, learning strategies, learning evaluation, interpersonal skills and self-directed learning ability of the two groups were higher than those before practice, and the study group was higher than the control group ( P<0.05). After 2 weeks, 4 weeks and 6 weeks of practice, the scores of the two groups of nursing students in evaluating the teaching quality of the teachers increased gradually compared with that of the first week of practice ( P<0.05). Conclusion:The "4C" teaching method combined with the two-way evaluation method in the nursing teaching of gastrointestinal surgery can improve the nursing students' theoretical knowledge, practical operation ability and self-directed learning ability, and is conducive to the improvement of teaching quality.
ABSTRACT
High quality is the premise for the implementation of high quality and good price for decoction pieces， and grade is the most direct manifestation of high quality of decoction pieces. However， there is still a lack of scientific and reasonable methods for evaluating the grade of decoction pieces， and it is urgent to establish a widely recognized and unified standard for the grade of decoction pieces to ensure the quality of the decoction pieces and guarantee the safety and efficacy of clinical use. Based on this， this paper focused on analyzing the problems of the current grade evaluation methods， such as unclear distinction between quality standards and grade standards， unreasonable selection of grade evaluation indicators， and inaccurate application of mathematical statistical methods. Based on the analysis of the grade evaluation of decoction pieces， this paper proposed four criteria for establishing the grade evaluation method of decoction pieces， namely universality， comprehensiveness， reliability and convenience， in order to establish a more reasonable and unified grade standard for decoction pieces and promote the quality improvement of decoction pieces and the development of the industry.
ABSTRACT
As adult stem cells, human mesenchymal stem cells (hMSCs) have the potential for self-replication, renewal, and multidirection differentiation. Their unique biological function determines their wide clinical indications. Researchers can define the quality attributes of hMSCs according to clinical expectations. The quality study of hMSCs should consider microbiological safety, biological safety, cell biological properties, and biological effectiveness. Quality evaluation is a common physical, chemical, and biological evaluation method for hMSCs. Traditional product safety evaluation strategies cannot fully adapt to current technology and product usage characteristics. Researchers have developed new, effective evaluation methods based on current technology. In terms of product efficacy evaluation strategies, an efficacy evaluation system has been gradually established and standardized according to the intended clinical use and based on quality studies, which can enable researchers to evaluate hMSCs products more comprehensively at different stages and processes. In this paper, the progress of quality research and evaluation of human mesenchymal stem cells was reviewed to provide a reference for the utilization of stem cells in the field of regenerative medicine.
ABSTRACT
OBJECTIVE@#To summarize the evaluation methods of return to sports (RTS) after anterior cruciate ligament reconstruction (ACLR) in recent years, in order to provide reference for clinical practice.@*METHODS@#The literature related to the RTS after ACLR was searched from CNKI, Wanfang, PubMed, and Foreign Medical Information Resources Retrieval Platform (FMRS) databases. The retrieval range was from 2010 to 2023, and 66 papers were finally included for review. The relevant literature was summarized and analyzed from the aspects of RTS time, objective evaluation indicators, and psychological evaluation.@*RESULTS@#RTS is the common desire of patients with ACL injury and doctors, as well as the initial intention of selecting surgery. A reasonable and perfect evaluation method of RTS can not only help patients recover to preoperative exercise level, but also protect patients from re-injury. At present, the main criterion for clinical judgement of RTS is time. It is basically agreed that RTS after 9 months can reduce the re-injury. In addition to time, it is also necessary to test the lower limb muscle strength, jumping, balance, and other aspects of the patient, comprehensively assess the degree of functional recovery and determine the different time of RTS according to the type of exercise. Psychological assessment plays an important role in RTS and has a good clinical predictive effect.@*CONCLUSION@#RTS is one of the research hotspots after ACLR. At present, there are many related evaluation methods, which need to be further optimized by more research to build a comprehensive and standardized evaluation system.

AIM:To explore the correlation and consistency of three tear assessment methods in the diagnosis of dry eye, which include the Schirmer Ⅰ test(SⅠt), tear meniscus height(TMH)measurement and a new generation of tear detection technology-Strip meniscometry tube(SMTube).METHODS: A diagnostic test study. A total of 183 dry eye outpatients(183 right eyes)in the Dry Eye Center of Henan Eye Hospital were enrolled from May to June 2021. The SⅠt, TMH and SMTube were performed on all patients, and the correlation and consistency of the measurement results were analyzed.RESULTS:The ocular surface disease index(OSDI)of all included patients was 43.75(31.25, 58.33), noninvasive breakup time(NIBUT)was 7.26(4.97, 9.37)s, and the results of SⅠt, TMH and SMTube were 6(2, 12)mm/5min, 0.18(0.14, 0.22)mm and 5(3,8)mm/5s, respectively; The results of correlation analysis: TMH was positively correlated with SMTube(rs=0.751, P<0.001), however, SⅠt had no correlation with TMH(rs=0.139, P=0.060)and SMTube(rs=0.019, P=0.799). The results of consistency analysis: TMH showed good consistency with SMTube(Kappa=0.794, P=0.044), however, SⅠt showed poor consistency with TMH(Kappa=0.271, P=0.074)and SMTube(Kappa=0.193, P=0.070)respectively.CONCLUSION:SMTube is a new, simple and convenient tool for evaluating tear volume. It has a good correlation and consistency with TMH measurement results. Therefore, it can replace TMH measurement, but cannot replace SⅠt in clinical application.
ABSTRACT
@#The UPLC fingerprint of colistimethate sodium was established for the study of quality consistency.The chromatographic column was Acquity UPLC? Peptide CSH C18 (2.1 mm × 150 mm, 1.7 μm).The mobile phase A was phosphate buffer-acetonitrile (19∶1), and the mobile phase B was phosphate buffer-acetonitrile (1∶1).The mobile phase was in gradient elution at a flow rate of 0.3 mL/min.The column temperature was set at 30 °C and the detection wavelength was 210 nm.The similarity of the fingerprints was analyzed with the Similarity Evaluation System for Chromatographic Fingerprint of Tradition Chinese Medicine (Version 2012) in combination with content determination of multiple index components to evaluate the quality consistency of imported and domestic bulk drugs.The result showed that both the original and generic bulk drugs met the specified limit requirements in the European Pharmacopoeia standards, and that their UPLC fingerprints were highly similar, indicating that the quality of the two substances was consistent.Establishing a fingerprint for similarity evaluation and combining it with the results of indicator component content determination as a comprehensive evaluation method for the study of drug quality consistency of complex components has the characteristics of fast, accurate, and comprehensive, which is helpful for drug quality evaluation and provides ideas for the evaluation of antibiotic quality consistency of complex components.

ABSTRACT
Traditional Chinese medicine(TCM) has unique advantages in the prevention and treatment of diseases owing to its holistic view and more than 2 000 years of experience in the clinical use of natural medicine. The "holistic" characteristic of TCM gives birth to a new generation of research paradigm featuring "network" and "system", which has been developing rapidly in the era of biomedical big data and artificial intelligence. Network pharmacology, a representative research field, provides new ideas and methods for the research of the interdiscipline of artificial intelligence and medicine, the analysis of massive biomedical data, and the transformation from data to knowledge. TCM plays an important role in proposing the core theory of "network target" and promoting the establishment and development of network pharmacology, and has taken the lead in formulating the first international standard of network pharmacology--Network Pharmacology Evaluation Method Guidance. In terms of theory, network target can systematically link drugs and diseases and quantitatively interpret the overall regulatory mechanism of drugs. In the aspect of method, network pharmacology is developing towards a research model that combines computational, experimental, and clinical approaches. This review introduces the resent important progress of TCM network pharmacology in predicting drug targets, understanding the biological basis of drugs and diseases, and searching for disease and syndrome biomarkers. Under the guidance of Network Pharmacology Evaluation Method Guidance, the development of network pharmacology is expected to become more and more standardized and healthy. Network target will help produce more high-quality research outcomes in TCM and effectively boost the modernization and internationalization of TCM.

ABSTRACT
The paper reviews systematically the main ancient medical books with the origin literature included on acupuncture prescription. It is found that the origin literature with acupuncture prescription in successive dynasties mainly focuses on Qin-Han and Jin-Yuan Dynasties. In Jin, Tang and Song Dynasties, as well as Ming and Qing Dynasties, the literature mainly records the experience of medical masters in the previous dynasties. By taking "headache" and "retention of urine" as examples, the origins on the literature of clinical acupuncture prescription are explored, the distribution rules and characteristics are summarized. Moreover, the evidences and evaluation method of quality grading were explored on the ancient books with the origin literature of acupuncture prescription involved.

OBJECTIVE：To p rovide reference for pharmacoecono mic study in China. METHODS ：The key steps in the operation process of efficiency frontier approach （EFA）were analyzed ；the similarities and differences of EFA with cost-utility analysis（CUA）and cost-effectiveness analysis （CEA）were compared on the basis of case demonstration ；the enlightenment of EFA to pharmacoeconomic evaluation and related decision-making in China were puts forward combined with the practice of China. RESULTS & CONCLUSIONS ：The research framework of EFA could be roughly divided into 5 parts：cost calculation ，benefit definition，model establishment ，incremental analysis and sensitivity analysis. Benefit indicators were the measurement indicators of health output in EFA ，including clinical indicators and comprehensive indicators ，among which comprehensive indicators were more widely used. When constructing the efficiency frontier ，the benefit of the intervention measures was generally taken as the ordinate and the cost of the intervention measures as the abscissa. The cost-benefit coordinate points of each alternative intervention measure in a specific disease field constituted the cost-benefit plane frontier. Researchers conducted economic evaluation by judging the relative position between each alternative intervention measure and the efficiency frontier. Thewillingness to pay threshold was numerically equal to the reciprocal of the ray slope outside the efficiency frontier. Generally speaking ，EFA was similar to CUA and CEA. All of them needed to clarify the cost and health output ，model analysis ， data source and uncertainty analysis ；however，EFA was different from CUA and CEA in intervention measures and control selection，expression form of evaluation results ，willingness to pay threshold ，etc. It is suggested that the payers in China can consider using EFA to calculate the willingness to pay threshold of specific disease areas to ensure the accessibility of some drugs in short supply ；establish a health insurance database of specific diseases to standardize the data quality and form a clear evaluation standard at the same time ，or combine a variety of pharmacoeconomic evaluation methods to enrich the application materials so as to ensure both clinical value and economy of the intervention measure.
ABSTRACT

ABSTRACT
Idiopathic thrombocytopenic purpura (ITP) is a common bloody disease with a high incidence in children, but its diagnostic method is exclusive diagnosis, and the existing detection techniques are mostly invasive, which may cause secondary injury to patients and also may increase the risk of disease. In order to make up for the lack of the detection method, this study made a preliminary exploration on the diagnosis of children's ITP from the perspective of infrared thermography. In this study, a total of 11 healthy children and 22 ITP children's frontal infrared thermal images were collected, and the pattern characteristic (PFD), average temperature (Troi) and maximum temperature (MAX) characteristics of 7 target areas were extracted. The weighted PFD parameters were correlated with the platelet count commonly used in clinical diagnosis, and the sensitivity and specificity of the weighted PFD parameters for children's ITP were calculated through the receiver operating characteristic curve (ROC). The final results showed that the difference of the weighted PFD parameters between healthy children and ITP children was statistically significant, and the parameters negatively correlated with platelet count. Under the ROC curve, the area under the curve (AUC) of this parameter is as high as 92.1%. Based on the research results of this paper, infrared thermography can clearly show the difference between ITP children and healthy children. It is hoped that the methods proposed in this paper can non-invasively and objectively describe the characteristics of ITP infrared thermal imaging of children, and provide a new ideas for ITP diagnosis.

ABSTRACT
At the beginning of 2009, the 38th principle of the Administrative Measures for Clinical Application of Medical Technology, issued by the former Ministry of Health, clearly pointed out that medical institutions should establish a hierarchical management system for surgery. Then the Trial of Administrative Measures for Surgical Classification of Medical Institutions was published and implemented in 2012, but the official introduction of surgical classification catalogue in the national level has not been seen. Therefore, the writing group of this expert consensus has organized numerous well-known experts and scholars in China, taking the three elements of the 38th principle of the Administrative Measures for Clinical Application of Medical Technology issued by the Ministry of Health--risk coefficient, complexity, and technical difficulty as the basic norm to grade scientifically through the four indicators of burn index, surgical area, surgical repair method, and anesthesia risk (each indicator with 4 grades and scores). The total score is then accumulated to divide four grades of operations. The Expert Consensus on Classification Evaluation Methods of Burn Surgery in China (2019 Version) is strategized together expecting to provide academic reference for the government departments to issue or further improve and perfect surgical classification catalogue in the national level as soon as possible, and lay a foundation for the stable development of burn discipline with the significance of national strategic reserve.
