The Occupational Classification Dictionary of the People's Republic of China (2015 Edition) has added a new occupation type, Medical Nursing Assistants, aiming to meet the strong demand for medical care in the context of the aging population in China.In order to standardize the services of medical nursing assistants for the elderly in home and community settings and contribute to healthy aging, the National Health Commission issued the " Service Standards for Medical Nursing Assistants of Older Adults in Home and Community" ( WS/ T 803—2022) on September 28, 2022.The standards regulate the service processes, service items and requirements, as well as service evaluation and improvement for elderly medical nursing assistants.The interpretation of the standard's formulation background, the compilation process, and the standard's content are as follows.

Given the opposing effects of Akt and AMP-activated protein kinase (AMPK) on metabolic homeostasis, this study examined the effects of deletion of Akt2 and AMPKα2 on fat diet-induced hepatic steatosis. Akt2–Ampkα2 double knockout (DKO) mice were placed on high fat diet for 5 months. Glucose metabolism, energy homeostasis, cardiac function, lipid accumulation, and hepatic steatosis were examined. DKO mice were lean without anthropometric defects. High fat intake led to adiposity and decreased respiratory exchange ratio (RER) in wild-type (WT) mice, which were ablated in DKO but not Akt2−/− and Ampkα2−/− mice. High fat intake increased blood and hepatic triglycerides and cholesterol, promoted hepatic steatosis and injury in WT mice. These effects were eliminated in DKO but not Akt2−/− and Ampkα2−/− mice. Fat diet promoted fat accumulation, and enlarged adipocyte size, the effect was negated in DKO mice. Fat intake elevated fatty acid synthase (FAS), carbohydrate-responsive element-binding protein (CHREBP), sterol regulatory element-binding protein 1 (SREBP1), peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), peroxisome proliferator-activated receptor-α (PPARα), PPARγ, stearoyl-CoA desaturase 1 (SCD-1), phosphoenolpyruvate carboxykinase (PEPCK), glucose 6-phosphatase (G6Pase), and diglyceride O-acyltransferase 1 (DGAT1), the effect was absent in DKO but not Akt2−/− and Ampkα2−/− mice. Fat diet dampened mitophagy, promoted inflammation and phosphorylation of forkhead box protein O1 (FoxO1) and AMPKα1 (Ser485), the effects were eradicated by DKO. Deletion of Parkin effectively nullified DKO-induced metabolic benefits against high fat intake. Liver samples from obese humans displayed lowered microtubule-associated proteins 1A/1B light chain 3B (LC3B), Pink1, Parkin, as well as enhanced phosphorylation of Akt, AMPK (Ser485), and FoxO1, which were consolidated by RNA sequencing (RNAseq) and mass spectrometry analyses from rodent and human livers. These data suggest that concurrent deletion of Akt2 and AMPKα2 offers resilience to fat diet-induced obesity and hepatic steatosis, possibly through preservation of Parkin-mediated mitophagy and lipid metabolism.

Cancer stem cells are currently under intensive investigation due to their capabilities for tumor initiation, self-renewal, and resistance to chemotherapy. CD133 is implicated in stemness and the malignancy of tumor cells. Here, we explored heat shock protein gp96 adjuvanted CD133 epitope vaccine against leukemia. We screened and identified three H2-Kd-restricted cytotoxic T lymphocyte (CTL) epitopes derived from CD133, CD133₄₁₉₋₄₂₈, CD133₇₀₂₋₇₁₀ and CD133₇₆₀₋₇₆₉. The immunogenicity and antitumor activity of the epitope vaccine using heat shock protein gp96 as adjuvant were further determined in CD133⁺ leukemia xenograft mice. Finally, we demonstrate that adoptive transfer of epitope-specific CTLs led to suppression of leukemia growth. Our data therefore provide the basis for designing a CD133 epitope vaccine to activate specific CTLs against CD133⁺ leukemia and other cancers.

Type 1 diabetes (T1D), the most prevalent human autoimmune disease, occurs in genetically susceptible individuals. Regulatory T cells (Tregs) are defective in T1D setting. Therefore, efforts to repair or restore Tregs in T1D may prevent or reverse this autoimmune disease. Here, we studied the potential role of rgp96 in preventing T1D, using non-obese diabetic (NOD) mice as an animal model. High-dose rgp96 immunization elicited efficient protection of mice against T1D, as evidenced by stable blood glucose, decreased disease incidence. Significantly increased CD4⁺ CD25⁺ Foxp3⁺ Tregs were observed in immunized mice. In vitro co-culture experiments demonstrated that rgp96 stimulation enhanced Treg proliferation and suppressive function by up-regulation of Foxp3 and IL-10. Our work shows that activation of Tregs by high-dose rgp96 immunization protects against T1D via inducing regulatory T cells and provides preventive and therapeutic potential for the development of an rgp96-based vaccine against T1D.
