Neuropathic pain is frequently comorbidity with cognitive deficits. Neuralized1 (Neurl1)-mediated ubiquitination of CPEB3 in the hippocampus is critical in learning and memory. However, the role of Neurl1 in the cognitive impairment in neuropathic pain remains elusive. Herein, we found that lumbar 5 spinal nerve ligation (SNL) in male rat-induced neuropathic pain was followed by learning and memory deficits and LTP impairment in the hippocampus. The Neurl1 expression in the hippocampal CA1 was decreased after SNL. And this decrease paralleled the reduction of ubiquitinated-CPEB3 level and reduced production of GluA1 and GluA2. Overexpression of Neurl1 in the CA1 rescued cognitive deficits and LTP impairment, and reversed the reduction of ubiquitinated-CPEB3 level and the decrease of GluA1 and GluA2 production following SNL. Specific knockdown of Neurl1 or CPEB3 in bilateral hippocampal CA1 in naïve rats resulted in cognitive deficits and impairment of synaptic plasticity. The rescued cognitive function and synaptic plasticity by the treatment of overexpression of Neurl1 before SNL were counteracted by the knockdown of CPEB3 in the CA1. Collectively, the above results suggest that the downregulation of Neurl1 through reducing CPEB3 ubiquitination and, in turn, repressing GluA1 and GluA2 production and mediating synaptic plasticity impairment in hippocampal CA1 leads to the genesis of cognitive deficits in neuropathic pain.

Objective To investigate the effect of ankle pump exercises,based on hemodynamic mechanisms,on the prevention of venous thrombosis in stroke patients.Methods A total of 110 stroke patients,admitted to a tertiary A hospital in Jiangsu Province between June 2023 and June 2024,were selected using a convenience sampling method.The patients were divided into an experimental group and a control group,with 55 patients in each group.The experimental group received ankle pump exercise nursing interventions based on hemodynamic mechanisms,while the control group received routine nursing interventions.The incidence of lower extremity deep vein thrombosis,Pittsburgh Rehabilitation Participation Scale scores,subjective perceived fatigue,and exercise self-efficacy scores were compared between 2 groups on the 7th day of hospitalization.Results No dropouts occurred in either group.The incidence of deep vein thrombosis was significantly lower in the experimental group than it in the control group(P=0.004).The Pittsburgh Rehabilitation Participation scores on day 1,3,5,and 7 were higher in the experimental group compared to them in the control group(P＜0.001).A significant time-dependent trend was observed in Pittsburgh Rehabilitation Participation scores(P=0.034).Subjective fatigue was significantly lower in the experimental group at various time points(P＜0.001).Both groups showed an increase in exercise self-efficacy over time(P=0.016),with the experimental group demonstrating higher exercise self-efficacy than the control group on the day before discharge(P=0.003).Conclusion Ankle pump exercises,based on hemodynamic mechanisms,can effectively reduce the incidence of deep vein thrombosis in stroke patients,enhance rehabilitation participation and exercise self-efficacy,without increasing subjective fatigue.

Objective:To develop a journey map for health management of patients with disability caused by accidental trauma from the social ecosystem theory perspective, so as to gain deeper insights into their actual needs during medical treatment and rehabilitation.Methods:The descriptive qualitative research was adopted. Purposeful sampling was employed to select patients with disability caused by accidental trauma admitted to the Trauma Center of the Department of Emergency and Critical Care Medicine at the First Affiliated Hospital with Nanjing Medical University between April and May 2024 for semi-structured interviews. Traditional content analysis method was employed to analyze the interview data.Results:From three dimensions of microsystem, mesosystem, and macrosystem, the needs and potential issues of medical treatment at different stages of the health management process for patients with disability caused by accidental trauma were analyzed, forming a patient journey map.Conclusions:Patients with disability caused by accidental trauma face prolonged periods of medical treatment, rehabilitation, and lifestyle readjustment, imposing significant burdens on themselves, their caregivers, and their families. Healthcare providers may proactively engage with patients based on their current and potential issues and needs, offer specialized guidance at critical junctures and meet the need of patients for continuity of care, thereby improving patients' quality of life and overall health outcomes.

Objective·To explore the predictive value of diuretic renal scintigraphy parameters such as 20-minute residual rate(R20)for pyeloplasty in children with congenital unilateral ureteropelvic junction obstruction(UPJO).Methods·The clinical data and diuretic renal scintigraphy results of 110 children with congenital unilateral UPJO who were first treated at the Department of Nuclear Medicine,Xinhua Hospital,Shanghai Jiao Tong University School of Medicine from August 2018 to August 2023 were retrospectively analyzed.The imaging results and the progress of hydronephrosis were followed up after the first diuretic renal scintigraphy.According to the outcome event of pyeloplasty due to the progression of hydronephrosis,the children were divided into operation group and non-operation group.Age,gender,side of hydronephrosis,and baseline diuretic renal scintigraphy parameters including blood perfusion rate(BPR),differential renal function(DRF),time to peak(Tmax),time to half(T1/2)and R20 were compared between the two groups.Logistic regression was used to analyze the effect of various parameters on the progression of hydronephrosis.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of diuretic renal scintigraphy parameters for surgical intervention.Wilcoxon test was used to compare the examination parameters of two diuretic renal dynamic imaging.Results·During the follow-up,60 children underwent pyeloplasty after progression,and the other 50 children did not progress.The differences in DRF,Tmax,T1/2 and R20 between the two groups of children at baseline were statistically significant(all P<0.05).Univariate and multivariate Logistic regression analysis showed that only R20 was an independent predictor of pyeloplasty(OR=4.730,95%CI 1.009-1.178,P=0.030).R20 predicted pyeloplasty with a sensitivity of 88.3%,specificity of 56%,the area under the ROC curve of 0.758(95%CI 0.667-0.850,P=0.000),and the cut-off value of 90.08%.During the follow-up,38 children underwent the second diuretic renal scintigraphy,and the DRF was lower than before.The difference between the two DRFs was statistically significant(Z=-2.589,P=0.010),especially in children with R20≥90.08%(Z=-2.166,P=0.030).R20 in the non-operation group decreased significantly compared with the baseline(Z=-2.062,P=0.039).However,R20 in the operation group was higher than baseline,but the difference was not statistically significant(P>0.05).Conclusion·R20 plays an important role in the prediction of pyeloplasty in children with congenital unilateral UPJO.For children with R20≥90.08%,pyeloplasty should be performed as soon as possible to prevent further deterioration of renal function.

Objective:To explore the therapeutic effect of traditional Chinese medicine formula Kuijie enema combined with Western medicine on patients with ulcerative colitis.Methods:A clinical prospective randomized trial was conducted, and 107 patients with ulcerative colitis admitted to the Shiyan People′s Hospital from January 2018 to December 2022 were included in the study. They were randomly divided into a combination group of 54 cases and a control group of 53 cases using a random number table method. Both groups of patients received the same basic treatment plan, and the combination group was treated with traditional Chinese medicine formula for ulcerative colitis enema on this basis. Both groups of patients were treated continuously for 4 weeks, We observed the differences in serum inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), monocyte chemokine 1 (MCP1)], Mayo score, endoscopic mucosal score, traditional Chinese medicine symptom score, and clinical treatment efficacy between two groups of patients before and after treatment.Results:After treatment, the serum levels of TNF-α, IL-6, and MCP1 in the two groups were lower than those before treatment, and IL-10 was higher (all P<0.05), and the changes of the above inflammatory factors were more obvious in the combined group, with statistically significant differences (all P<0.05). After treatment, the Mayo score and endoscopic mucosal score of both groups of patients decreased compared to before treatment (all P<0.05), and the Mayo score and endoscopic mucosal score of patients in the combination group were lower than those in the control group (all P<0.05). After treatment, the traditional Chinese medicine syndrome scores of both groups decreased compared to before treatment (all P<0.05), and the combined group patients had lower scores for diarrhea, abdominal pain, pus and bloody stools, urgency and weight, and anal burning than the control group, with statistical significance (all P<0.05). Both groups of patients were treated continuously for 4 weeks, and the overall efficacy distribution of the combination group was better than that of the control group ( Z=-2.274, P=0.023). Conclusions:The combination of traditional Chinese medicine formula Kuijie enema liquid and Western medicine can more effectively reduce the degree of inflammation in patients with ulcerative colitis, alleviate clinical symptoms, and improve clinical treatment effectiveness.

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 explore the application effect of continuous quality improvement based on trauma team activation model in emergency triage.Methods:This study is a historical controlled study. A total of 12 215 trauma patients receiving initial treatment in the Emergency Department of the First Affiliated Hospital with Nanjing Medical University from January 2020 to June 2021 were selected as the research objects by the convenience sampling method, and 3 896 trauma patients from January to June 2020 were enrolled as the baseline group, and 4 054 patients from July to December 2020 were enrolled as the phaseⅠ improvement group, and 4 265 patients from January to June 2021 were enrolled as the phaseⅡ improvement group. The baseline group adopted the one-tiered trauma team activation model, which was evaluated and decided by the first-visiting doctor. The phaseⅠ improvement group received the one-tiered trauma team activation model, which was evaluated and decided by pretest triage nurses. The stageⅡ improvement group conducted the two-tiered trauma team activation model, which was evaluated and decided by pretest triage nurses. The trauma team activation time, overtriage rate and undertriage rate were compared between the three groups.Results:The trauma team activation time of the phaseⅠ improvement group and phaseⅡ improvement group was shorter than that of the baseline group, and the difference was statistically significant ( P<0.05). The overtriage rate of the phaseⅡ improvement group was lower than that of the baseline group and the phaseⅠ improvement group, and the differences were statistically significant ( P<0.05). The underage rate of the three groups were <5%, and the differences were not statistically significant ( P>0.05) . Conclusions:The two-tiered activation of trauma team mode led by nurses can shorten the trauma team activation time, reduce the overtriage rate and undertriage rate, improve the quality of trauma team activation.
