Objective:To investigate the association of R wave peak time(RWPT)with severity of coronary artery disease and short-term prognosis in patients with acute coronary syndrome(ACS).Methods:A total of 133 ACS patients who were treated in Shenzhen Longhua District Central Hospital between January 2019 and June 2022 and received coronary angiography were selected.According to number of diseased coronary arteries,they were divided into single-vessel coronary disease group(n=43),double-vessel coronary disease group(n=51)and multi-vessel coronary disease group(n=39);according to severity of coronary artery disease,they were divided into mild group(n=40),medium group(n=48)and severe group(n=45).ECG indexes were compared among groups with different number of diseased coronary arteries and severity of coronary artery disease.Pearson correlation analysis was used to analyze corre-lation between ECG indexes and Gensini score;patients were divided into major adverse cardiovascular events(MACE)group(n=46)and no MACE group(n=87)according to presence of MACE during hospitalization.Clinical data were compared between two groups,and multivariate Logistic regression was used to analyze risk factors of MACE during hospi-talization in ACS patients.Results:QRS duration and RWPT significantly increased according to the order of single-ves-sel,double-vessel and multi-vessel coronary disease group(P＜0.05 or＜0.01);QRS duration and RWPT significantly increased according to the order of mild,medium and severe group(P＜0.05 or＜0.01).Pearson correlation analysis indi-cated that QRS duration and RWPT were significant positively correlated with Gensini score in ACS patients(r=0.222,0.557,P=0.010,＜0.001).Multivariate Logistic regression analysis indicated that hypertension,diabetes,RWPT,Gensini score and multi-vessel disease were independent risk factors for MACE during hospitalization in ACS patients(OR=3.171～9.360,P＜0.05 or＜0.01).Conclusion:RWPT is closely related to the severity of coronary artery disease in ACS patients.RWPT detection helps to guide risk stratification and secondary prevention of ACS patients,therefore im-prove their short-term prognosis.

Medium spiny neurons (MSNs) in the striatum, which can be divided into D1 and D2 MSNs, originate from the lateral ganglionic eminence (LGE). Previously, we reported that Six3 is a downstream target of Sp8/Sp9 in the transcriptional regulatory cascade of D2 MSN development and that conditionally knocking out Six3 leads to a severe loss of D2 MSNs. Here, we showed that Six3 mainly functions in D2 MSN precursor cells and gradually loses its function as D2 MSNs mature. Conditional deletion of Six3 had little effect on cell proliferation but blocked the differentiation of D2 MSN precursor cells. In addition, conditional overexpression of Six3 promoted the differentiation of precursor cells in the LGE. We measured an increase of apoptosis in the postnatal striatum of conditional Six3-knockout mice. This suggests that, in the absence of Six3, abnormally differentiated D2 MSNs are eliminated by programmed cell death. These results further identify Six3 as an important regulatory element during D2 MSN differentiation.

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.

Mouse cortical radial glial cells (RGCs) are primary neural stem cells that give rise to cortical oligodendrocytes, astrocytes, and olfactory bulb (OB) GABAergic interneurons in late embryogenesis. There are fundamental gaps in understanding how these diverse cell subtypes are generated. Here, by combining single-cell RNA-Seq with intersectional lineage analyses, we show that beginning at around E16.5, neocortical RGCs start to generate ASCL1
