Objective: The aim of this study was to assess the management of early mobilization(EM) in Chinese intensive care units(ICUs).Methods: This survey used a cross-sectional, observational design. A total of 65 tertiary and secondary hospitals were enrolled by convenience sampling and investigated using self-designed ***: We identified 69 ICUs in Jiangsu, China(response rate: 94.2%). 74.2%(1,004/1,353) of the nurses and nursing managers from 65 ICUs reported mobility practice. For the mobility level, 98.1%(1,327) reported use of in-bed exercise, 5.7%(77) sitting on a side of bed, 21.7%(294) transfer to chair, and 2.4%(33) walking. The most frequently reported barriers to early mobility were unplanned extubation, nursing resource, and absence of physical therapist. Nurses’ educational backgrounds, nursing experience, the lack of nursing resources, absence of physician, and the weakness of patient were the factors that influenced ICU early rehabilitation(P<0.01).Conclusions: Although implementation rates for EM in critically ill patients are high, the activity level is generally poor in most of the involved ICUs.

An efficient one-pot synthetic protocol was developed for the synthesis of imidazo[ 1,2-a]pyridines from easily available starting materials： Aromatic ketones, α/βunsaturated ketones,β-keto esters and 2- aminopyridines. The present reaction proceeded well in MeOH under the media of I2/CuO. By using this method, the marketed drug zolimidine could be prepared easily with 95% yield. All these target products were characterized by NMR, HRMS and IR spectra. Furthermore, the target compound 3fa was determined bv X-ray crystallographic analysis.

Generating high-value chemical compounds by catalytically converting carbon resources—typically derived from coal and biomass, etc.—is crucial. It is more meaningful to achieve“carbon neutrality” and lower production costs by utilizing industrial waste carbon sources, such as steel mill waste gases,which are typically intended for direct emission or burning into CO_(2).
