The International Liaison Committee on Resuscitation published the 2022 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations in Circulation, Resuscitation, and Pediatrics in November 2022. This consensus updates and recommends important aspects of cardiopulmonary resuscitation based on recently published resuscitation evidence. Herein, we interpret the consensus focusing on adult cardiopulmonary resuscitation including basic life support (ventilation techniques, compressions pause, transport strategies during resuscitation, and resuscitation procedures in drowning), advanced life support (target temperature management, point-of-care ultrasound as a diagnostic tool during cardiac arrest, vasopressin and corticosteroids for cardiac arrest, and post-cardiac arrest coronary angiography), cardiopulmonary resuscitation education/implementation/team (survival prediction after resuscitation of patients with in-hospital cardiac arrest, basic life support training, advanced life support training, blended learning for life support education, and faculty development approaches for life support courses) and recovery positions on rescue scene. This consensus provides important guidance for clinical practice and clear hints for the development of clinical research.
ObjectiveTo explore course content and teaching-learning strategies of advanced nursing practice in graduate nursing education, so as to provide reference for nursing schools to develop relevant courses.MethodsA teamof course teachers was set up, and the course was developed. The course was implemented in grade 2015 and 2016 graduate nursing students. The students’ perception and evaluation of course contents, teaching methods, teaching quality, curriculum value and course satisfaction were collected through questionnaires and interviews.ResultsA totalof 23 students were enrolled. The mean scores of teaching quality, curriculum value and course satisfaction were 93.48±1.01, 51.04±4.88, and 17.00±2.28, respectively. Students recognized the necessity and the importance of including the advanced nursing practice in each specialty in the course content, and hoped to add in practice sections.ConclusionsIt is advisable to include the advanced nursing practice in each specialty as well as the practice section, so as to strengthen the students’ concrete understanding of the advanced nursing practice. Seminar and discussion are the teaching methods with first priority.
Obiective lt;brgt;To investigate the change of the activity of proliferation in cultivated Muuml;ller cells treated by advanced glycation endoproducts (AGEs), and the effect of these changes on expression of occludin in bovine retinal vascular endothelial cells (BREC). lt;brgt;Methods lt;brgt;The cultivated Muuml;ller cells were devided into normal growth group and cultured with AGEs group. The cultured BREC were devided into 4 groups:group 1, without any medium; group 2, with normal growth Muuml;ller cell medium (MCM); group 3,MCM treated by AGEs; group 4, without cell as the control. Enzyme-linked immuno sorbent assay was used to detect the content of occludin in the medium in the 4 groups. lt;brgt;Results lt;brgt;The content of expression of occludin was the most in group 2, less in group 1, and the least in group 3. lt;brgt;Conclusion lt;brgt;AGEs may promote the abnormal proliferation of Muuml;ller cells and inhibit the expression of occludin in BREC. lt;brgt;(Chin J Ocul Fundus Dis, 2006, 22: 28-30)
In November 2019, the American Heart Association updated guidelines for cardiopulmonary resuscitation (CPR) and emergency cardiovascular care. This update is not a comprehensive revision of the 2015 version. The updates for children and newborns mainly include three aspects: ① Pediatric basic life support: A. It is recommended that emergency medical dispatch centers offer dispatcher-assisted CPR instructions for presumed pediatric cardiac arrest. B. It is recommended that emergency dispatchers provide CPR instructions for pediatric cardiac arrest when no bystander CPR is in progress. ② Pediatric advanced life support: A. The bag-mask ventilation is reasonable compared with advanced airway interventions (endotracheal intubation or supraglottic airway) in the management of children during out-of-hospital cardiac arrest (OHCA). B. The extracorporeal CPR may be considered for pediatric patients with cardiac diagnoses who have in-hospital cardiac arrest (IHCA) in settings with existing extracorporeal membrane oxygenation protocols, expertise, and equipment. C. Continuous measurement of core temperature during targeted temperature management is recommended; for infants or children between 24 hours and 18 years of age who remain comatose after OHCA or IHCA, targeted temperature management is recommened. ③ Neonatal resuscitation: A. In term and late-preterm newborns (≥35 weeks of gestation) receiving respiratory support at birth, the initial use of 21% oxygen is reasonable. B. One hundred percent oxygen should not be used to initiate resuscitation because it is associated with excess mortality. C. In preterm newborns (<35 weeks of gestation) receiving respiratory support at birth, it may be reasonable to begin with 21% to 30% oxygen.
American Heart Association updated the guidelines for cardiopulmonary resuscitation (CPR) and emergency cardiovascular care in November 2019. This focused update incorporates the systematic review conducted by the International Liaison Committee on Resuscitation, an expert group consisting of hundreds of international resuscitation scientists, to identify the new evidence supporting the basic and advanced life support and first aid in emergency medical care. This focused update involves the life chain of CPR (dispatcher-assisted CPR and cardiac arrest centers), advanced cardiovascular life support (advanced airways, vasopressors, and extracorporeal CPR), and first aid for presyncope. This present review aims to interpret these updates by reviewing the literature and comparing the recommendations in this update with previous guidelines.
Objective To determine the association of -429T/C and G1704T polymorphisms in the receptor for advanced glycation end products gene with proliferative diabetic retinopathy (PDR). Methods Case-control study. From the Beijing Desheng Diabetic Eye Study cohort of 1467 patients with type 2 diabetes mellitus (T2DM),atotal of 97 patients with PDR and 105 diabetic patients without retinopathy (DWR, duration of diabetes 15 years) were included for this study. Questionnaires were collected and general ophthalmologic examinations were performed. Biochemical analysis was conducted. DNA was extracted from peripheral venous blood. The -429T/C and G1704T single nucleotide polymorphisms were detected by the means of PCR-restrication fragment length polymorphisms. Results The frequency distribution of -429T/C in DWR group was 81.0% in TT, 16.1% in TC, 2.9% in CC. The frequency distribution of -429T/C in PDR group was 77.3% in TT, 20.6% in TC, 2.1% in CC. There was no significant statistical difference between the two groups (χ2=0.40, P > 0.05). Frequency of the -429T/C minor alleleCin the DWR and PDR group were 11.0% and 12.4%, respectively, with no significant statistical difference between the two groups (χ2=0.20，P > 0.05). The frequency distribution of G1704T in DWR group was 66.7% in GG, 29.5% in GT, 3.8% in TT. The frequency distribution of G1704T in PDR group was 78.4% in GG, 21.6% in GT. There was no significant statistical difference between the two groups (χ2=3.44, P > 0.05). Frequency of the G1704T minor alleleTin the DWR and PDR group were 18.6% and 10.8%, respectively, in which significant difference was found within the two groups (χ2=4.79, OR=1.88，95%CI: 1.06 - 3.33, P > 0.05). Conclusions G1704T polymorphism is associated with PDR presence and 1704G allele may increase the risk of PDR.
[Abstract]High-grade histologic subtypes of lung adenocarcinoma, such as micropapillary and solid patterns, are characterized by high invasiveness, increased risk of recurrence, and poor prognosis. Early preoperative identification of these subtypes is crucial for achieving individualized treatment and improving clinical outcomes. This review summarizes the clinical features, imaging manifestations, molecular mechanisms, and diagnostic advances related to these aggressive patterns. Studies have shown that micropapillary and solid subtypes are more common in male smokers, often present as solid nodules, and demonstrate strong predictive value in FDG-PET metabolic parameters and CT-based radiomics models. At the molecular level, EGFR mutations are more frequently observed in micropapillary types, whereas solid subtypes are often associated with high PD-L1 expression and TP53 mutations, indicating distinct therapeutic strategies for targeted and immunotherapies. In addition, serum markers such as CEA and CYFRA21-1, along with inflammatory indices like NLR and SII, may serve as auxiliary tools for subtype identification. Histologic subtypes of lung adenocarcinoma are evolving from descriptive classifications into critical determinants of treatment decisions and precision management. Clinicians should incorporate comprehensive histologic evaluation into individualized therapeutic planning. Multimodal integration technologies, combined with artificial intelligence algorithms, are advancing the accurate preoperative prediction and management of high-risk subtypes, thereby facilitating early diagnosis and stratified treatment of lung adenocarcinoma.
