Reprogramming of energy metabolism is one of the basic characteristics of cancer and has been proved to be an important cancer treatment strategy. Isocitrate dehydrogenases (IDHs) are a class of key proteins in energy metabolism, including IDH1, IDH2, and IDH3, which are involved in the oxidative decarboxylation of isocitrate to yield α-ketoglutarate (α-KG). Mutants of IDH1 or IDH2 can produce d-2-hydroxyglutarate (D-2HG) with α-KG as the substrate, and then mediate the occurrence and development of cancer. At present, no IDH3 mutation has been reported. The results of pan-cancer research showed that IDH1 has a higher mutation frequency and involves more cancer types than IDH2, implying IDH1 as a promising anti-cancer target. Therefore, in this review, we summarized the regulatory mechanisms of IDH1 on cancer from four aspects: metabolic reprogramming, epigenetics, immune microenvironment, and phenotypic changes, which will provide guidance for the understanding of IDH1 and exploring leading-edge targeted treatment strategies. In addition, we also reviewed available IDH1 inhibitors so far. The detailed clinical trial results and diverse structures of preclinical candidates illustrated here will provide a deep insight into the research for the treatment of IDH1-related cancers.

Objective To explore the application and method of World Health Organization Rehabilitation Competency Framework (RCF) in rehabilitation human resource management, and provide theoretical and practical reference for rehabilitation human resource management.Methods Based on the International Standard Classification of Occupations issued by the International Labour Organization, the application scope of RCF was systematically analyzed. The theoretical framework of rehabilitation human resource management based on RCF was constructed in combination with competency-based human resource management framework. On this basis, taking rehabilitation nurses as an example, the corresponding management methods and paths are proposed from four aspects of human resource management, including career management, recruitment and selection, training and development, and performance appraisal and salary management.Results Based on RCF, the theoretical framework of human resource management for rehabilitation nursing positions was constructed, and the main contents and processes of human resource management based on RCF were clarified from four aspects: recruitment and selection, training and development, performance appraisal and salary management, and career management. Occupational competency of rehabilitation professionals in International Standard Classification of Occupations was analyzed by RCF.Conclusion The rehabilitation competency framework constructed by WHO can be used to supplement the responsibilities of rehabilitation-related professionals in the International Standard Classification of Occupations issued by the International Labour Organization. RCF serves as a tool for practice managers and rehabilitation professionals in identifying selection criteria, learning objectives, and professional title assessment criteria. It can also be used in recruitment and selection, training and development, performance appraisal, salary management and career management in the field of rehabilitation human resource management.

Objective To explore the theory and method of performance evaluation for rehabilitation workers based on the World Health Organization Rehabilitation Competency Framework (RCF).Methods Using the theoretical framework and methods of the RCF, we analyzed rehabilitation workers' related competencies from the five dimensions, namely practice, professionalism, learning and development, management and leadership, and research, integrating core values and beliefs, competencies and behaviors, activities and tasks, and knowledge and skills, to construct a comprehensive evaluation method and pathway for rehabilitation workers' performance.Results Based on the RCF, which confirms the job competency requirements for rehabilitation workers, a multi-dimensional, multi-level and standardized performance evaluation index framework was formed. For example, performance evaluation system of physical therapists was consisted of five primary indicators and 26 secondary indicators from the combination of RCF and job standards.Conclusion The rehabilitation worker performance evaluation based on the RCF can evaluate the performance of rehabilitation workers in a scientific, standardized and comprehensive way. It analyzes the performance of rehabilitation workers in a multi-dimensional and systematic manner with the competence of rehabilitation workers as the center, and evaluates the quality and effectiveness of the performance of rehabilitation workers at different levels of proficiency, which makes the performance evaluation of rehabilitation workers more scientific and comprehensive, and enables rehabilitation workers to understand proficiency and clarify the gap, to promote rehabilitation workers to continuously improve their own level and enhance the quality of rehabilitation services.

In this study,a functionalized covalent-organic framework(COF)was first synthesized using porphyrin as the fabrication unit and showed an edge-curled,petal-like and well-ordered structure.The synthesized COF was then introduced to prepare porous organic polymer monolithic materials(POPMs).Two com-posite POPM/COF monolithic materials with rod shapes,referred to as sorbent A and sorbent B,were prepared in stainless steel tubes using different monomers.Sorbents A and B exhibited relatively uniform porous structures and enhanced specific surface areas of 153.14 m2/g and 80.01 m2/g,respectively.The prepared composite monoliths were used as in-tube solid-phase extraction(SPE)sorbents combined with HPLC for the on-line extraction and quantitative analytical systems.Indole alkaloids(from Catharanthus roseus G.Don and Uncaria rhynchophylla(Miq.)Miq.Ex Havil.)contained in mouse plasma were extracted and quantitatively analyzed using the online system.The two composite multifunctional monoliths showed excellent clean-up ability for complex biological matrices,as well as superior selec-tivity for target indole alkaloids.Method validation showed that the RSD values of the repeatability(n=6)were≤3.46％,and the accuracy expressed by the spiked recoveries was in the ranges of 99.38％-100.91％and 96.39％-103.50％for vinca alkaloids and Uncaria alkaloids,respectively.Furthermore,sorbents A and B exhibited strong reusability,with RSD values≤5.32％,which were based on the peak area of the corresponding alkaloids with more than 100 injections.These results indicate that the composite POPM/COF rod-shaped monoliths are promising media as SPE sorbents for extracting trace compounds in complex biological samples.

Inflammation is the defense response of the living tissues possessing vascular system to stimulations of various injury factors ,which plays a vital role in the initiation and progression of many major diseases .Drugs used to treat inflammation in the clinical mainly include non‐steroidal anti‐inflammatory drugs (NSAIDs) ,steroidal anti‐inflammatory drugs (SAIDs) and traditional Chinese medicine .As synthetic anti‐inflammatory drugs used in clinical currently have obvious adverse reactions , more and more attention were paid to seek anti‐inflammatory drugs from natural medicines .Reviews reported before mainly fo‐cus on anti‐inflammation mechanism of natural medicine ,however ,there are few reports on the summary of anti‐inflammatory natural products .Active natural products which were reported to possess anti‐inflammatory effects in recent years were summa‐rized in order to provide information for further study of anti‐inflammatory drugs research .

Linalool is an important monoterpene, and widely used in food, pharmaceutical and cosmetic industry. The low concentration in plants and the difficulties in extraction restrict its large scale production. Saccharomyces cerevisiae can provide the monoterpene precursor, geranyl diphosphate (GPP) through its endogenous isoprenoid pathway. Therefore, it could be used as the host for monoterpene production. However, the weak metabolic flux through the isoprenoid pathway leads to the insufficient supply of GPP, and results in low monoterpene productivity. In order to increase the metabolic flux, we constructed the integrated expression plasmid pRS305-tHMG1 and free expression plasmid pYLIS-IDI1 to enhance the expression levels of isopentenyl diphosphate isomerase (IDI1) and a truncated 3-hydroxyl-3-methylglutaryl-CoA reductase gene (tHMG1). The two plasmids were separately transformed into S. cerevisiae CEN.PK2-1C, resulting in strains LS01 and LS02. The plasmid pYLIS-IDI1 was further transformed into strain LS01, resulting in strain LS03. GC-MS analysis showed that the linalool concentration was increased by 1.3 times and reached (127.71 +/- 7.68) microg/L. In conclusion, enhancement of the supply of GPP precursors through the regulation of isoprenoid pathway could increase the linalool production in S. cerevisiae.
