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.

ObjectiveTo investigate the current situation of rehabilitation therapists' work, and analyze the factors related to their career development and transformation. MethodsFrom September, 2022 to January, 2023, 153 rehabilitation therapists in Weifang were investigated with a cross-sectional questionnaire, using general questionnaire, Job Satisfaction Scale for Grassroots Health Technicians, Social Responsibility Scale, Job Role and Identity Inventory, and Employee Turnover Scale. ResultsThe majority of rehabilitation therapists interviewed were male (52.28%), under 35 years old (88.24%), with a bachelor's degree (77.78%), income less than 5 000 yuan a month (46.40%), and less than five years of service (48.36%). The work time was (7.78±0.84) hours a day, (5.39±0.51) days a week. The favorable rate of the physical environment of work was 67.32%, and the favorable rate of the interpersonal relationship environment of work was 80.39%. The score of professional identity was (3.61±0.84), the score of job satisfaction was (3.62±0.97), the score of social responsibility was (3.53±0.79), and the score of turnover was (2.39±1.10). Education level, job satisfaction, and social responsibility were the main factors related to the employee turnover (P < 0.05). ConclusionThe overall educational level of rehabilitation therapists is relatively low, and the human resource structure needs to be optimized. There is a significant difference between academic education and continuing education, and career development needs to be improved. The main factors related to career development and transformation are education level, job satisfaction, and social responsibility.

SARS-CoV-2 has caused tens of thousands of infections and more than one thousand deaths. There are currently no registered therapies for treating coronavirus infections. Because of time consuming process of new drug development, drug repositioning may be the only solution to the epidemic of sudden infectious diseases. We systematically analyzed all the proteins encoded by SARS-CoV-2 genes, compared them with proteins from other coronaviruses, predicted their structures, and built 19 structures that could be done by homology modeling. By performing target-based virtual ligand screening, a total of 21 targets (including two human targets) were screened against compound libraries including ZINC drug database and our own database of natural products. Structure and screening results of important targets such as 3-chymotrypsin-like protease (3CLpro), Spike, RNA-dependent RNA polymerase (RdRp), and papain like protease (PLpro) were discussed in detail. In addition, a database of 78 commonly used anti-viral drugs including those currently on the market and undergoing clinical trials for SARS-CoV-2 was constructed. Possible targets of these compounds and potential drugs acting on a certain target were predicted. This study will provide new lead compounds and targets for further and studies of SARS-CoV-2, new insights for those drugs currently ongoing clinical studies, and also possible new strategies for drug repositioning to treat SARS-CoV-2 infections.

Cells utilize calcium ions (Ca) to signal almost all aspects of cellular life, ranging from cell proliferation to cell death, in a spatially and temporally regulated manner. A key aspect of this regulation is the compartmentalization of Ca in various cytoplasmic organelles that act as intracellular Ca stores. Whereas Ca release from the large-volume Ca stores, such as the endoplasmic reticulum (ER) and Golgi apparatus, are preferred for signal transduction, Ca release from the small-volume individual vesicular stores that are dispersed throughout the cell, such as lysosomes, may be more useful in local regulation, such as membrane fusion and individualized vesicular movements. Conceivably, these two types of Ca stores may be established, maintained or refilled via distinct mechanisms. ER stores are refilled through sustained Ca influx at ER-plasma membrane (PM) membrane contact sites (MCSs). In this review, we discuss the release and refilling mechanisms of intracellular small vesicular Ca stores, with a special focus on lysosomes. Recent imaging studies of Ca release and organelle MCSs suggest that Ca exchange may occur between two types of stores, such that the small stores acquire Ca from the large stores via ER-vesicle MCSs. Hence vesicular stores like lysosomes may be viewed as secondary Ca stores in the cell.

Thyroid is an important endocrine organ of the human body for secreting necessary thyroid hormone, which is important to promote the development of human skeleton and nervous system.Thyroid hormone is used to evaluate thyroid function, changing by different race, gender, age, living habits, living area, iodine intake levels and so on.Various laboratory testing instrument and supporting reagents also can affect thyroid hormone reference range.At present, laboratory only sets special thyroid hormone reference interval for pregnant women, and does not set reference interval according to specific age and gender.
