Objective To investigate the status of cardiopulmonary resuscitation (CPR) in patients with sudden cardiac arrest (CA) in the emergency department. Methods A multicenter prospective observational study was conducted. The patients with CA admitted to 13 hospitals from 6 provinces in four different regions, including North China, Southern China, East China, Southwest China, from July 1st, 2015 to July 31st, 2017 were enrolled. A modified Utstein template was applied to collect clinical data, including general data, CA related data and prognosis, and primary outcome indicator was the return of spontaneous circulation (ROSC) rate, and the secondary outcome indicator was 28-day survival rate. The influence factors of ROSC were screened by Logistic regression analysis. Results The data of 613 patients with CA in 13 hospitals were enrolled. The ROSC rate in Beijing and Guangdong Province was higher, but there was no significant difference in 28-day survival rate among hospitals from different provinces. ① In 613 patients with CA, there were 413 patients suffering from in-hospital cardiac arrest (IHCA, 67.4%), and 200 suffering from out-hospital cardiac arrest (OHCA, 32.6%). 208 patients had ROSC at least once (33.9%), only 20 patients survived within 28 days (3.3%). ROSC rate in IHCA patients was significantly higher than that in OHCA patients [37.3% (154/413) vs. 27.0% (54/200), P < 0.01]. There was no statistic difference in 28-day survival rate between patients with IHCA and OHCA. The patients received manual chest compression, electric defibrillation, or epinephrine ≤ 4 mg had higher ROSC rate, but 28-day survival rate showed no significant difference. Multivariate Logistic regression analysis showed that IHCA [odds ratio (OR) = 1.893, 95% confidence interval (95%CI) = 1.253-2.858, P = 0.002], manual chest compression (OR = 0.506, 95%CI = 0.348-0.736, P = 0.000), electric defibrillation (OR = 0.458, 95%CI = 0.300-0.699, P = 0.000), and total adrenalin ≤ 4 mg (OR = 0.317, 95%CI = 0.216-0.464, P = 0.000) were the protective factors of ROSC in CA patients. ② In 200 OHCA patients, there were 49 patients had ROSC (24.5%), only 5 patients survived (2.5%). The patients aging < 65 years, with witnesses of CPR, received manual chest compression, electric defibrillation, or epinephrine ≤ 4 mg had higher ROSC rate, and the ROSC rate was higher in ambulances than that at home and in public sites, but 28-day survival rate showed no significant difference. Multivariable Logistic regression analysis showed that age < 65 years old (OR = 2.749, 95%CI = 1.192-6.336, P = 0.018), manual chest compressions (OR = 0.196, 95%CI =0.072-0.535, P = 0.001), electric defibrillation (OR = 0.263, 95%CI = 0.108-0.641, P = 0.003), total adrenaline dose ≤4 mg (OR = 0.122, 95%CI = 0.049-0.303, P = 0.000) and the ambulance CA (OR = 2.441, 95%CI = 1.334-4.468, P = 0.004) were protective factors of ROSC in OHCA patients. Conclusions The survival of sudden CA in emergency department was still poor. Early electric defibrillation, manual chest compression, CA occurred in hospital or in ambulance, and witness CPR can improve the ROSC rate of CA patients. Excessive use of adrenaline is not beneficial to patients with CA. Clinical Trial Registration Clinical Trials, NCT01987245.

Objective:To analyze the efficacy and safety of nalbuphine for analgesia in patients with non-mechanical ventilation in intensive care unit (ICU).Methods:From December 2018 to August 2021, a multicenter randomized controlled clinical study was conducted to select non-mechanical ventilation patients with analgesic needs admitted to ICU of four hospitals in Henan Province and Guizhou Province. Patients were randomly assigned to nalbuphine group and fentanyl group. The nalbuphine group was given continuous infusion of nalbuphine [0.05~0.20 mg/(kg·h)], and the fentanyl group was given continuous infusion of fentanyl [0.5~2.0 μg/(kg·h)]. The analgesic target was critical-care pain observation tool (CPOT) score<2. The observation time was 48 hours. The primary endpoint was CPOT score, the secondary endpoints were Richmond agitation-sedation score (RASS), ICU length of stay, adverse events, and proportion of mechanical ventilation. The quantitative data of the two groups were compared by t test or Mann-Whitney U test. The enumeration data were compared by chi square test or Fisher exact probability method. The data at different time points between groups were compared by repeated measures analysis of variance. Results:A total of 210 patients were enrolled, including 105 patients in the nalbuphine group and 105 patients in the fentanyl group. There was no significant difference in baseline data between the two groups (all P>0.05). There was no significant difference in CPOT score between nalbuphine group and fentanyl group at each time point after medication ( P>0.05), the CPOT score of both groups at each time point after medication was significantly lower than that before medication, and the analgesic target could be achieved and maintained 2 hours after medication. There was no significant difference in RASS between the two groups at each time point after medication ( P>0.05), which was significantly lower than that before medication, and the target sedative effect was achieved 2 hours after medication. There was no significant difference in ICU length of stay between nalbuphine group and fentanyl group [5.0(4.0,7.5) d vs. 5.0(4.0,8.0) d, P=0.504]. The incidence of delirium, nausea and vomiting, abdominal distension, pruritus, vertigo and other adverse events in the nalbuphine group was lower than that in the fentanyl group (all P<0.05). There was no significant difference in the incidence of other adverse events such as deep sedation, hypotension and bradycardia between the two groups (all P>0.05). The incidence of respiratory depression in nalbuphine group was not significantly different from that in fentanyl group ( P>0.05), but the proportion of mechanical ventilation was significantly lower than that in the fentanyl group [1.9% (2/105) vs. 8.6%(9/105), P=0.030]. Conclusions:Nalbuphine could be used for analgesia in ICU patients with non-mechanical ventilation. The target analgesic effect could be achieved within 2 hours, and it had a certain sedative effect with a low incidence of adverse reactions.

Objective:To construct a competency-oriented clinical practice teaching system for undergraduate anesthesia nursing students.Methods:From December 2022 to April 2023, based on the theory of job competency, a preliminary expert consultation questionnaire was drafted on the basis of literature analysis and semi-structured interviews.

Porcine reproductive and respiratory syndrome (PRRS) is a highly contagious disease caused by porcine reproductive and respiratory syndrome virus (PRRSV), which causes great economic losses. At the moment, no effective neutralizing antibody is available for scientific research and treatment. Therefore, developing a method for screening the neutralizing monoclonal antibodies is of great significance for the prevention and treatment of PRRSV and the screening of antigen sites. Monoclonal antibodies have been widely used in the treatment and diagnosis of many human and animal diseases. Therefore, screening effective neutralizing antibodies for different pathogens is an urgent task. Among the methods for monoclonal antibody screening, B cell immortalization is an effective method to obtain neutralizing monoclonal antibody. Specifically, in this study, the bcl-6 and bcl-xl genes were connected by f2a and then the yielded product was ligated to a vector for retrovirus packaging. The swine lymphocytes immunized with PRRSV were infected the yielded mature viruses and cultured in the complete medium containing CD40L and IL21 cytokines. Then, CD21 was used as the marker to screen B cells with the magnetic bead method. Finally, monoclonal B cells were obtained and the secretion of antibodies was tested. The results showed that the plasmid, either being transfected alone or with the packaged plasmids, could be expressed, and that the packaged retrovirus could infect the cells. Moreover, the infected lymphocytes secreted antibodies, so did the screened B cells. Therefore, the method for screening monoclonal antibody against PRRSV was successfully established.
