Age-dependent loss of skeletal muscle mass and function is a feature of sarcopenia, and increases the risk of many aging-related metabolic diseases. Here, we report phenotypic and single-nucleus transcriptomic analyses of non-human primate skeletal muscle aging. A higher transcriptional fluctuation was observed in myonuclei relative to other interstitial cell types, indicating a higher susceptibility of skeletal muscle fiber to aging. We found a downregulation of FOXO3 in aged primate skeletal muscle, and identified FOXO3 as a hub transcription factor maintaining skeletal muscle homeostasis. Through the establishment of a complementary experimental pipeline based on a human pluripotent stem cell-derived myotube model, we revealed that silence of FOXO3 accelerates human myotube senescence, whereas genetic activation of endogenous FOXO3 alleviates human myotube aging. Altogether, based on a combination of monkey skeletal muscle and human myotube aging research models, we unraveled the pivotal role of the FOXO3 in safeguarding primate skeletal muscle from aging, providing a comprehensive resource for the development of clinical diagnosis and targeted therapeutic interventions against human skeletal muscle aging and the onset of sarcopenia along with aging-related disorders.

Objective:To explore the expression of circ-KEL in patients with acute myeloid leukemia (AML) and the effect and mechanism of circ-KEL on leukemic cells.Methods:The expression of circ-KEL was detected by quantitative real-time polymerase chain reaction in bone marrow mononuclear cells collected from 116 patients with AML and 40 healthy donors. The correlation of circ-KEL expression with the clinical characteristics of patients with AML was further systematically analyzed. The modulations among circ-KEL, miR-335-5p, and LRG1 were predicted through bioinformatics analysis and validated by dual luciferase assay. Cell proliferation and apoptosis were detected using CCK8 and flow cytometry.Results:The expression of circ-KEL was significantly elevated in patients with AML compared with the healthy controls (Relative expression level, -Δct, AML: -7.117±1.831; control: -8.669±1.771, P<0.001) . Moreover, patients with high circ-KEL expression have significantly worse overall survival. The level of circ-KEL in patients with AML was downregulated after chemo-treatment. In addition, circ-KEL could serve as the sponge of miR-335-5p and regulate LRG1. Bioinformatics analysis showed that miR-335-5p correlates with good prognosis and was negatively associated with LRG1. LRG1 could promote cell proliferation and inhibit cell apoptosis. Our results also exhibited the higher expression of LRG1 in patients with AML. Moreover, circ-KEL exerted functional effects via sponging miR-335-5p and regulating LRG1. Conclusion:circ-KEL expresses highly in patients with AML and correlates with poor prognosis, suggesting its important role in the genesis and progress of AML.

Objective: To carry out the 4^th round of third-party evaluation on the implementation and effect of the 1^st year of the 2^nd Phase National Healthcare Improvement Initiative(abbreviated as Initiative)since 2015. Methods: The 4^th round of the evaluation survey adopted the same methods, organization and execution, and technical roadmap as the former three rounds of evaluations. Results: The 4^th round of evaluation was carried out from 18 March to 9 April, 2019 at 185 public hospitals in 31 provinces(autonomous regions, municipalities directly under the Central Government)and Xinjiang Production and Construction Corps.Facility survey, health professional survey and patient survey were conducted at each of the sample health facilities. A total of 120 782 valid questionnaires were collected from 144 non-psychiatric health facilities, 16 246 valid questionnaires were obtained from 41 psychiatric health facilities, and 252 cases of outstanding departments/hospitals in healthcare improvement were also collected. The average overall scoring of the 12 dimensions to assess Initiative implementation at 144 non-psychiatric health facilities was 84.4%. The overall outpatient satisfaction scoring was 91.1%, 96.7%for the inpatients. The overall inpatient satisfaction(family members inclusive) at 41 psychiatric health facilities was 93%. Areas remaining to be improved include day-surgery, telemedicine and medical social work. Compared with technical services, non-technical care should be further strengthened. The compensation, workload and work environment of the healthcare providers are still to be improved. Conclusions The implementation of the Initiative by health facilities has been greatly improved. The percentage of health facilities and patients who had positive perceptions of improved doctor-patient relationship has been increasing. Patient care experiences at public hospitals have been generally improved, and the implementation of promoting traditional Chinese Medicine practices also made progress. However, work satisfaction of healthcare providers was found to be rather low, compared to the high level of patient satisfaction.

The 2nd round of the third-party evaluation of the National Healthcare Improvement Initiative was made during Dec 2016 and Jan 2017.The methods, organization and implementation of the survey and the technical roadmap were the same as those of the 1st round of evaluation.The total number of respondents was 94 218,including 19 773 doctors,24 315 nurses,29 105 outpatients and 21 025 inpatients. 142 typical cases were collected from sample hospitals.The key findings showed that, the National Healthcare Improvement Initiative has been implemented quite well in the 2nd year, achievements and challenges exist side by side.The overall satisfaction rate of both outpatients and inpatients was good, both were about 90%.Further improvement is expected.Hospital staff have been actively involved in this Initiative,but they are not satisfied with their working environments and compensations.
