ABSTRACT
The awake prone position plays an important role in the treatment of hypoxemia and the improvement of respiratory distress symptoms in non-intubated patients. It is widely used in clinical practice because of its simple operation, safety, and economy. To enable clinical medical staff to scientifically and normatively implement prone position for awake patients without intubation, the committees of consensus formulation, guided by evidence-based methodology and Delphi method, conducted literature search, literature quality evaluation and evidence synthesis around seven topics, including indications and contraindications, evaluation, implementation, monitoring and safety management, termination time, complication prevention and health education of awake prone position. After two rounds of expert letter consultation, Expert consensus on implementation strategy of awake prone positioning for non-intubated patients in China (2023) was formulated, and provide guidance for clinical medical staff.

Enteral nutrition plays an irreplaceable role in the nutritional treatment of critically ill patients. In order to help clinical medical staff to manage the common complications during the implementations of enteral nutrition for critically ill patients, the consensus writing team carried out literature retrieval, literature quality evaluation, evidence synthesis. Several topics such as diarrhea, aspiration, high gastric residual volume, abdominal distension, etc. were assessed by evidence-based methodology and Delphi method. After two rounds of expert investigations, Expert consensus on prevention and management of enteral nutrition therapy complications for critically ill patients in China (2021 edition) developed, and provided guidance for clinical medical staff.
ABSTRACT
BACKGROUND:Under normal physiological conditions, there is a homeostasis between the osteogenic and adipogenic differentiation of human bone marrow mesenchymal stem cel s. Osteogenic differentiation is an important process in the formation of skeleton in which differentiated and mature osteoblasts are indispensable. OBJECTIVE:To explore the role of miR-106a and its target gene, bone morphogenetic protein receptor 2 (BMPR2) in the differentiation of human bone marrow mesenchymal stem cel s into osteoblasts. METHODS:Human bone marrow mesenchymal stem cel s were induced to differentiate into osteoblasts by osteoblast-specific induction medium, and this process was detected by western blot and alkaline phosphatase staining. Overexpression of miR-106a was elicited by transfecting miR-106a mimics and the BMPR2 knockdown achieved by RNA interference. The expression levels of miR-106a and BMPR2 were detected by real-time PCR and western blot, respectively. The interaction of miR-106a and BMPR2 was verified by TargetScan software and dual luciferase report experiment assay. RESULTS AND CONCLUSION:The expression of miR-106a was decreased whereas the expression of BMPR2 increased with the progress of osteogenesis differentiation. When miR-106a was overexpressed, alkaline phosphatase activity was declined and the expressions of runt-related transcription factor 2 and osteocalcin, markers of osteogenesis differentiation, both decreased. The expression of BMPR2 was decreased as wel . BMPR2 was predicted to be the target gene of miR-106a by TargetScan software and this prediction proved by dual luciferase report experiments assay. Additional y, osteogenesis differentiation was inhibited by knocking down the expression of BMPR2. These results indicate that miR-106a regulates the differentiation of bone marrow mesenchymal stem cel s into osteoblasts by targeting BMPR2.
ABSTRACT
PURPOSE: To identify the clinical features and outcomes of endogenous endophthalmitis in Korea. MATERIALS AND METHODS: We reviewed 18 patients with endogenous endophthalmitis at 2 Korean hospitals, treated over a 14 year period between January 1993 and December 2006. RESULTS: The comorbidities observed in these cases were diabetes mellitus and liver cirrhosis. The most common pathogens, which were found in 7 patients each (38.9%), were Klebsiella pneumonia and Pseudomonas aeruginosa. All patients were treated with systemic antibiotics and fortified topical antibiotics. A surgical approach including vitrectomy was performed in 9 cases (50.0%). The prognosis was generally poor, and visual acuity improved slightly in 6 patients (33.3%). CONCLUSION: In this study, diabetes mellitus and Klebsiella pneumonia showed a close relationship with endogenous endophthalmitis, respectively. Endogenous endophthalmitis is a serious risk to sight and careful attention to establishing the diagnosis and management may decrease the ocular morbidity.
