We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

OBJECTIVE:
To study the effect of β-sheet blocking peptide H102 on the expression of AMPK-mTOR autophagy pathway-related protein in APP/PS1 double transgenic AD mice.
METHODS:
Thirty male APP/PS1 transgenic male AD mice of 6 months old were randomly divided into AD group and H102 intervention group, and C57BL/6J male mice of the same age were used as control group (n=15). The mice in the HF group were administered with 5 μl (5.8 mg/kg) of H102 polypeptide solution through the nasal cavity at the same time period, and the mice in the control group and the AD group were given the same amount of blank adjuvant solution daily. The memory recognition ability was tested by a new object recognition experiment 30 days after continuous administration. Immunohistochemistry and Western blot were used to detect the expressions of phosphorylated AMP-activated protein kinase(P-AMPK),phosphorylated mammalian target of rapamycin (P-mTOR) and ratio of LC32to LC31(LC3II/I )in brain tissue.
RESULTS:
Compared with the control group, the new object recognition index (RI) of the AD group was significantly lower (P<0.05), and the P-AMPK and LC3II/I ratios in the brain of the mice were significantly lower (P<0.05). The expression of P-mTOR protein was increased significantly (P<0.05). Compared with the AD group, the RI of the H102 intervention group was increased significantly (P<0.05), and the P-AMPK and LC3II/I ratios in the brain tissue of the mice were increased significantly (P<0.05). The expression of P-mTOR protein was decreased significantly (P<0.05).
CONCLUSION
H102 can improve the recognition and memory ability of AD mice by activating the AMPK-mTOR autophagy-related pathway.
