Precise management of the activity dose is a core component of the(early mobilization,EM)plan for ICU patients.However,the lack of clinical practice guidelines related to EM dose of existing programs hinders the implementation and development of EM in ICU patients to some extent.Therefore,this review focuses on 4 aspects,covering the definition of activity dose,assessment tools,the current clinical implementation status,and implications for future nursing.The aim is to systematically review the assessment tools and intervention strategies for the activity dose of EM in ICU patients,providing a reference for optimization of EM programs.

To summarize the nursing experience of a patient with T-cell precursor acute lymphoblastic leukemia complicated with excessive dynamic airway collapse.Key nursing points include:efficient treatment of airway collapse to avoid causes of airway hyper responsiveness;avoiding the blockage of phlegm suppository,ensuring a safe and smooth airway;preventing the risks of hemorrhage and thrombosis,and strictly implement hospital infection prevention and control measures.After active rescue and careful nursing care,the patient was transferred back to the general thoracic surgery ward 13 days later,improved 17 days later,and was admitted to the cancer hospital for continued treatment.

Naturally derived metabolites are valuable resources for drug research and development, and play an important role in the treatment of diseases. As the "second genome" of the body, gut microbiota is rich in metabolic enzymes, which interacts with external substances such as drugs, thus affecting the progression of diseases. This article summarizes the interaction between gut microbiota-producing enzymes and natural medicines, and focuses on the impact of this interaction on disease progression, hoping to provide new ideas for the development and pharmacological mechanism of natural medicines.

To summarize the nursing care experience of a case of idiopathic multicentric Castleman's disease TAFRO syndrome complicated with diffuse alveolar hemorrhage.Key points of nursing:prone position ventilation with high blood risk nursing observation and bleeding prevention;early rehabilitation exercise and the reduction of the lymphedema;the optimization of transitional care to avoid unplanned returns to the ICU.The patient was transferred to the respiratory ward for further treatment after 19 days,and 33 days later,she recovered and was discharged.At 1 month of follow-up after discharge,the patient recovered well.

Nonalcoholic fatty liver disease (NAFLD) is a genetic and environmental factor-associated metabolic disease that can lead to fibrosis, cirrhosis and hepatocellular carcinoma. In recent decades the prevalence of NAFLD has increased, but effective pharmacotherapy is limited. Treatment regimens in traditional Chinese medicine (TCM) have made significant contributions to the control of NAFLD, but underlying mechanisms are far less elucidated. Increasing evidence suggests that gut microbiota play a crucial role in the pathogenesis and development of diseases including NAFLD. The outcomes of such research open a new approach in identifying the molecular mechanisms of TCM. Here we review the evidence that gut microbiota might be a target in the treatment NAFLD using TCM.

The aim of this study was to evaluate the effects and mechanisms of berberine (BBR) against dexamethasone (Dex)-induced metabolic disorders. 3T3-L1 cells were differentiated by Dex treatment and then treated with BBR (2.5, 5, 10 μmol·L^-1). Lipid accumulation was detected using oil-red O staining. After review and approval of the ethics committee of the Institute of Materia Medica, Peking Union Medical College, Chinese Academy of Medical Sciences, C57BL/6N mice were randomly divided into three groups. In the BBR treatment group, mice were subcutaneously implanted with an osmotic pump containing Dex and gavaged with BBR (100 mg·kg^-1·day^-1) for 4 weeks. The model control group was implanted with a Dex osmotic pump with no other treatment. Mice given a saline-filled osmotic pump were used as a negative control. During the study, food intake and body weight were measured weekly. Subcutaneous fat and visceral fat was detected by MRI. At the end of the experiment the plasma levels of total cholesterol (CHO), triglyceride (TG), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), glucose (Glu), and muscle mass were measured. The expression of peroxisome proliferator-activated receptor γ (PPARγ) and AMP-activated protein kinase α (AMPKα) in 3T3-L1 cells and epididymal fat of C57BL/6N mice was evaluated through RT-PCR and Western blot analysis. The results showed that BBR inhibited Dex-induced adipocyte differentiation in 3T3-L1 preadipocytes by up to 23% in a dose-dependent manner. In C57BL/6N mice, berberine alleviated hyperlipidemia and hyperglycemia and reduced visceral fat accumulation induced by Dex. The results from RT-PCR and Western blot analysis showed that BBR reduced PPARγ expression and increased the phosphorylation of AMPKα in 3T3-L1 cells as well as in adipose tissue. Berberine might alleviate Dex-induced metabolic disorder and visceral fat accumulation by modulating PPARγ and AMPK expression.
