Objective:To evaluate the clinical efficacy of individualized postural management guided by lung ultrasound (LUS) in neonates with grade Ⅲ bronchopulmonary dysplasia (BPD).Methods:This prospective randomized controlled trial enrolled neonates diagnosed with grade Ⅲ BPD at Guangdong Second People's Hospital Affiliated to Jinan University from July 2022 to December 2024, who were randomly assigned to control or intervention groups. The control group received conventional postural management (head elevation 15°-30°, supine-left lateral-right lateral-prone positioning with 2-hour rotations), while the intervention group underwent additional LUS examinations every 12 hours for dynamic posture adjustment based on pulmonary findings. Outcomes included LUS signs (pleural line abnormalities, A-line disappearance, B-line increases, cystic hyperaeration, alveolar-interstitial syndrome, consolidation) and primary endpoints (post-diagnosis oxygen therapy duration, invasive mechanical ventilation duration, and hospital stay). Secondary outcomes comprised new complications (pulmonary hemorrhage, necrotizing enterocolitis, BPD-associated pulmonary hypertension, grade Ⅲ-Ⅳ intracranial hemorrhage, retinopathy of prematurity). Intergroup comparisons used two independent samples t-tests and Chi square tests. Results:Among 49 eligible neonates, 47 were randomized (intervention group=24; control group=23), with 40 completing the study (20 per group after exclusions). At day 7, the intervention group showed significantly lower rates of pleural line abnormalities [55% (11/20) vs. 90% (18/20), χ2=6.14, P=0.013], A-line disappearance [50% (10/20) vs. 80% (16/20), χ2=3.95, P=0.046], B-line increases [50% (10/20) vs. 85% (17/20), χ2=5.58, P=0.018], alveolar-interstitial syndrome [65% (13/20) vs. 95% (19/20), χ2=5.62, P=0.017], and consolidation [50% (10/20) vs. 80% (16/20), χ2=3.95, P=0.046]. The intervention group also demonstrated shorter invasive ventilation [(9.5±2.3) vs. (11.6±3.5) days, t=2.18, P=0.035] and hospital stay [(58.9±4.9) vs. (63.2±6.4) days, t=2.33, P=0.025] post-diagnosis, with no significant differences in new complication rates (all P>0.05). Conclusion:LUS-guided postural management improves pulmonary pathology, reduces respiratory support duration and hospitalization, without increasing complications in grade Ⅲ BPD neonates.

Objective To investigate serum levels of Zonulin and Claudin-5 in patients with schizophrenia (SZ) and their relationship with the severity of psychiatric symptoms. Methods 98 patients with SZ treated in the Third Hospital of Heilongjiang Province form April 2019 to April 2022 were selected as the SZ group,and 50 healthy people who underwent physical examination were selected as the control group. Enzyme-linked immunosorbent assay was used to detect serum levels of Zonulin and Claudin-5. Pearson correlation analysis was used to analyze the relationship between serum Zonulin and Claudin-5 levels and clinical parameters in patients with SZ. Logistic regression was used to analyze the risk factors for SZ. Receiver operating characteristic curve was used to analyze the diagnostic value of serum Zonulin and Claudin-5 for SZ. Results The serum level of Zonulin in SZ group(7.91±0.52μg/L)was higher than that in control group (2.31±0.24μg/L),and the serum level of Claudin-5(12.17±2.34ng/L)was lower than that in control group(26.78±5.15 ng/L),the differences were statistically significant (t=72.235,23.740,all P<0.05).The total scores of Positive and Negative Symptom Scale (PANSS) score,positive and negative symptom scores,general psychiatric symptom scores was positively correlated with serum Zonulin (r=0.660～0.720,all P<0.05),and negatively correlated with serum Claudin-5 (r=-0.720～-0.622,all P<0.05).Serum Zonulin,PANSS total score,positive symptom score and general psychopathology symptom score were risk factors for SZ,and Claudin-5 was a protective factor (all P<0.05).The AUC(95％CI)of serum Zonulin and Claudin-5 combined for SZ diagnosis was 0.932(0.891～0.959),which was higher than that of serum Zonulin and Claudin-5 single diagnosis were 0.814(0.779～0.847),0.846(0.811～0.882),respectively,and the differences were statistically significant (Z=5.145,4.210,all P<0.05). Conclusion The increase in serum Zonulin levels and the decrease in Claudin-5 levels in SZ patients are related to the severity of their mental symptoms. The combined detection of serum Zonulin and Claudin-5 has high diagnostic value for SZ.

Objective:To understand the information needs and experiences of primary caregivers of patients in the emergency resuscitation room of the emergency department, and to provide a reference for clinical staff to meet caregivers′ information needs as well as to develop targeted and effective health information support for doctors and patients.Methods:A descriptive phenomenological research method was used to conduct semi-structured interviews with primary caregivers of 14 patients in the emergency resuscitation room of the First Affiliated Hospital of Nanjing Medical University from November 2023 to February 2024 through purposive sampling, and the Colaizzi 7-step analysis method was applied to summarize and analyze the interview data and refine the themes.Results:Totally 14 respondents aged 28-66, including 6 males and 8 females. Four themes were refined including diverse information needs, information access dilemma, integration of doctor-patient information for joint decision-making and communication, and desire for information and emotional support.Conclusions:The information needs of primary caregivers of patients in the emergency department were diverse, and caregivers were eager to seek patient-related information and crave emotional support and communication when faced with the onset of a patient's illness. Healthcare professionals should strengthen the assistance of caregivers′ information needs to improve the experience of patients and caregivers in medical consultation services and realize the sustainable development of the doctor-patient relationship.

Objective To observe the effect of cluster emergency nursing in treating patients with chlorfenapyr poisoning. Methods A retrospective analysis was performed for the treatment and nursing processes of 6 patients with chlorfenapyr poisoning. Results Among the 6 patients with chlorfenapyr poisoning, 5 cases were orally poisoned and one case was poisoned by respiratory tract and skin absorption of toxins. All of the 6 patients with chlorfenapyr poisoning were treated through the green channel for poisoning treatment, and multidisciplinary cooperation cluster treatment and nursing as well as toxicant detection were carried out. One patient was excluded because no chlorfenapyr component was detected in the toxicant detection; the remaining 5 patients had different degrees of fever, fatigue, nausea and vomiting and other symptoms in the early stage, and among them, 4 patients had high fever and aggravated degree of consciousness disturbance in the later stage of the disease, and died of ineffective treatment for 2 to 11 days after poisoning (one patient was out of contact and was expected to die), with a mortality rate of 80%. Conclusion There is no specific antidote for chlorfenapyr poisoning, and the mortality rate is extremely high. After poisoning, blood, urine and other specimens should be collected as soon as possible for toxic examination. At the same time, early gastric lavage (within 6 hours), intestinal adsorption, gastrointestinal catharsis, enema and other symptomatic treatments should be given. Continuous blood purification should be performed as soon as possible to remove blood toxins, and extracorporeal membrane oxygenation can be performed if conditions permit.

Objective:To retrieve, evaluate and integrate the evidence related to the preparation process for initiating extracorporeal cardiopulmonary resuscitation in hospital, so as to provide reference for clinical implementation of extracorporeal cardiopulmonary resuscitation.Methods:According to the evidence-based nursing method and the 6S evidence model, guidelines, clinical decisions, expert consensus, systematic review and other literatures related to the preparation process for initiating extracorporeal cardiopulmonary resuscitation in hospital were searched from National Guideline Clearinghouse, Scottish Intercollegiate Guidelines Network, National Institute for Health and Care Excellence, and other websites, UpToDate, The Cochrane Library, PubMed, Embase, CNKI, Wanfang and other databases. The retrieval date limit was from the establishment of the database to May 20, 2023. Researchers assessed the quality of the included articles, and extracted and summarized the evidence that met the quality standards.Results:A total of 11 articles were included, including 2 guidelines, 6 expert consensuses, 1 systematic review and 2 quasi-experimental studies. A total of 18 pieces of evidences were summarized from 6 aspects, including medical conditions, team building, materials management, operation mechanism, pre-initiating treatment and initiating judgment.Conclusions:This study summarizes the evidence of preparation process for initiating extracorporeal cardiopulmonary resuscitation in hospital, which can provide reference for promoting the implementation of extracorporeal cardiopulmonary resuscitation. Future studies still need to focus on team building, personnel training and assessment, and optimisation of the management system, so as to improve the efficiency and readiness of treatment.

Objective To explore the effects of dexmedetomidine combined with desflurane anesthesia on cerebral oxygen metabolism,sedation depth and cerebral function in liver cancer patients undergoing partial hepatic lobectomy.Methods A total of 30 liver cancer patients undergoing partial hepatic lobectomy at the Affiliated Cancer Hospital of Zhengzhou University from March to September 2022 were selected as the research subjects,they were divided into control group(n=15)and observation group(n=15)according to different anesthesia methods.Patients in both groups underwent partial open hepatectomy,and they were given the same anesthesia induction method.The patients in the control group received desflurane for anesthesia mainte-nance,while patients in the observation group received dexmedetomidine combined with desflurane for anesthesia maintenance.The anesthesia recovery indexes including the postoperative recovery time,recovery time of spontaneous breathing,eye-opening time of patients between the two groups were compared.The arterial oxygen saturation(SaO2),cervical vein oxygen saturation(SjvO2),arterial partial pressure of oxygen(PaO2)and partial pressure of venous oxygen of patients were detected by blood gas analyzer before anesthesia induction(T0),at the completion of anesthesia induction(T,),at 10 minutes after hepatic portal occlusion(T2),after hepatic lobectomy(T3)and after surgery(T4),and arterio-venous oxygen content difference(AVDO2)and cerebral oxygen extraction rate(CEO2)were calculated.The sedation depth of patients was evaluated by bispectral index(BIS)and patient state index(PSI)at T0,T1,T2,T3 and T4.The cerebral function of patients was evaluated by the Glasgow-Pittsburgh cerebral performance category scale at 3 months after surgery.The incidence of postoperative adverse reactions of patients between the two groups was compared.Results The postoperative recovery time,recovery time of sponta-neous breathing and eye-opening time of patients in the observation group were significantly shorter than those in the control group(P＜0.05).There was no significant difference in SaO2 of patients between the two groups at different time points(P＞0.05).At T2 and T3,SjvO2,AVDO2 and CEO2 of patients in the observation group were significantly lower than those in the control group(P＜0.05),but there was no significant difference in SjvO2,AVDO2 and CEO2 of patients between the two groups at the other time points(P＞0.05).At T2,T3 and T4,BIS and PSI of patients in the observation group were significantly lower than those in the control group(P＜0.05),but there was no significant difference in BIS and PSI of patients between the two groups at T0 and T1(P＞0.05).In the control group,there were 11 patients with postoperative brain function in grade 1,3 patients in grade Ⅱ and 1 patient in grade Ⅲ;in the observation group,there were 12 patients in grade Ⅰ and 3 patients in gradeⅡ.There was no significant difference in postoperative grading of brain function between the two groups(x2=1.044,P＞0.05).There was no significant difference in the total incidence of postoperative adverse reactions between the control group and observation group[20.00％(3/15)vs 26.67％(4/15),x2=0.186,P＞0.05].Conclusion Dexmedetomidine combined with desflurane anesthesia can shorten anesthesia recovery time,improve anesthesia depth and reduce cerebral oxygen metabolism in patients undergoing liver cancer surgery,which has no effect on cerebral function,showing good safety.
