Objective:To construct a nursing norm for extracorporeal membrane oxygenation in adults, so as to provide a reference for improving the nursing care of adult extracorporeal membrane oxygenation.Methods:The first draft was developed through literature search and expert discussion. From September to October 2023, 16 experts were selected using the Delphi method to conduct two rounds of expert consultation on the first draft, and the final draft was revised with reference to the experts' comments. The expert positivity coefficient was expressed as the effective recovery rate of the questionnaire, and the degree of expert authority was evaluated with the authority coefficient, and the degree of harmonization of expert opinions was assessed with the Kendall's harmony coefficient.Results:Literature search screened a total of four guidelines and five expert consensus. In the two rounds of consultation, the effective recovery rates of the questionnaires were all 100% (16/16), and the expert authority coefficients were all 0.900, and the Kendall's harmony coefficients of the overall indicators were 0.581 and 0.666, respectively (both P<0.01). The final constructed nursing norm for extracorporeal membrane oxygenation in adults included five primary indicators, 27 secondary indicators, and 17 tertiary indicators. Conclusions:The constructed nursing norm for extracorporeal membrane oxygenation in adults is scientific, reliable and feasible, and can guide clinical nursing staff to carry out nursing care for extracorporeal membrane oxygenation.

Objective To develop and validate a model to predict the risk of radiation-induced lung injury (RILI) and assess its clinical feasibility. Methods Clinical data from 125 patients with non-small cell lung cancer (NSCLC) were included in the study. The patients were divided into training group (88 cases) and validation group (38 cases). Key predictive factors were identified using univariate and multivariate logistic regression analyses combined with least absolute shrinkage and selection operator (LASSO) regression. A predictive model was constructed and evaluated using a nomogram, receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis. Results The key variables identified by the model were tumor volume (P = 0.017), Eastern Cooperative Oncology Group performance status score (P = 0.035), 95% of the minimum dose to the target volume (P = 0.028), percentage of bilateral lung volume receiving 20 Gy of radiation (P < 0.001), and neutrophil-to-lymphocyte ratio (P = 0.021). The ROC curve showed that the areas under the curve (AUC) for the model in the training and validation groups were 0.987 and 0.992, respectively, indicating good predictive ability. The calibration curve and decision curve further confirmed the accuracy and clinical practicability of the model. Conclusion The predictive model proposed in this study can accurately assess the risk of developing RILI in patients with NSCLC who have undergone radiotherapy, demonstrating its potential value in clinical practice.

Objective:To investigate the clinicopathological features, diagnosis and differential diagnosis of adrenal cortical carcinoma (ACC) in children.Methods:Twenty-five children with ACC diagnosed in the Department of Pathology, Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai, China from March 2014 to August 2022 were retrospectively analyzed. The related literature was reviewed.Results:A total of 25 children with ACC were collected, including 11 males and 14 females, with a male to female ratio of 1.0∶1.3. The patient ages ranged from 8 months to 14 years (median, 4 years). Eighteen cases with clinical data had functional tumors (18/22, 81.8%) presenting with virilization or precocious puberty (15/18), symptoms related to hypercortisolism (8/18) or endocrine symptoms mixed with both (5/18), while 3 cases (3/22, 13.6%) had unknown clinical data. The clinical manifestations of four patients with nonfunctional tumors were an abdominal mass and/or abdominal pain, walking instability and others. Grossly, the average maximum diameter of the tumor was 9.4 cm. Most of the tumors were nodular and partially encapsuled. The cut surfaces were gray or gray brown, soft with hemorrhage. Histologically, the tumor cells were diffusely distributed, separated by a vascular-rich network. The tumor cells were large, with distinct nucleoli, abundant eosinophilic or clear cytoplasm, and round or oval nuclei. The mitotic index was high, and atypical mitoses were common. Necrosis, calcification, capsule invasion or/and venous invasion were present. In some cases, the tumor invaded the surrounding soft tissues or kidneys. Immunohistochemically, the tumor cells were diffusely positive for syn and SF1 and focally positive for α-inhibin, Melan A and Calretinin, but negative for CgA. Ki-67 proliferation index ranged from 2%-90%. TP53 gene status was examined in 7 cases, in which mutations were detected in 4 cases. Follow-up data was obtained in 21 patients, among whom 18 received chemotherapy and 3 received radiotherapy. Distant metastasis occurred in 13 patients. Median progression-free survival (PFS) was 11.2 months and median overall survival (OS) was 54.7 months. Patients aged less than 5 years had a better prognosis for OS ( P<0.05) than the older ones (≥5 years), but a similar PFS ( P>0.05). Male patients and Ki-67 proliferation index <15% had a better prognosis tendency for OS, but there was no statistically significant difference ( P>0.05). Conclusions:ACC in children is a rare, often functional tumor associated with Li-Fraumeni genetic syndrome and has a poor prognosis. Diagnosis and differential diagnosis require a combination of morphological, phenotypic and clinical analysis.

Objective:To observe the effect of combining robot-assisted gait training (RAGT) with task-oriented training (TOT) on the walking ability of children with dyskinetic cerebral palsy (DCP).Methods:Sixty DCP children were randomly divided into a conventional intervention group, an RAGT group, and a combined intervention group, each of 20. All of the children received conventional rehabilitation therapy, while the RAGT and combined intervention groups were additionally provided with RAGT, and RAGT combined with TOT, respectively. Before the experiment and after 12 and 24 weeks of treatment, the subjects′ walking ability was evaluated using the 10-metre walk test (10MWT), and the D energy zone (standing position) and the E energy zone (walking, running and jumping) of the Gross Motor Function Measurement-88 (GMFM-88) instrument.Results:After 12 and 24 weeks of treatment, the average 10MWT speed and D and E energy zone scores of all three groups had improved significantly. After 24 weeks the combined group′s averages on all three measures were significantly better than those of the other two groups.Conclusion:RAGT combined with TOT and conventional rehabilitation training significantly improves the walking ability of DCP children.

Purpose To investigate the expression of Clau-din18.2 and its relationship with clinicopathological parameters and prognosis in Epstein-Barr virus-associated gastric cancer(EBVaGC),and also to analyze the correlation between the ex-pression of Claudin18.2 and PD-L1,ARID1A,and HER2.Methods Tissue samples of 694 patients received radical gas-trectomy,and 25 cases of EBVaGC were selected according to EBER results and matched one by one.Immunohistochemistry was employed to assess the expression levels of Claudin18.2,PD-L1,ARID1A and HER2 in EBVaGC and non-EBVaGC.Ka-plan-Meier survival analysis was performed for analyzing the re-lationship between the expression of Claudin18.2,PD-L1 and ARID1A and the prognosis of gastric cancer patients,and the survival curve was drawn.Spearman correlation analysis was used to assess the respective relationships between Claudin18.2 and PD-L1,ARID1A,and HER2.Results The positive/high expression rates of Claudin18.2 in EBVaGC were 76％and 64％respectively.Furthermore,the positive/high expression rates of Claudin18.2 in non-EBVaGC were 32％and 20％,respective-ly.Claudin18.2 expression showed positively correlations with the tumor site(proximal stomach)in gastric cancer patients.In addition,compared with non-EBVaGC,PD-L1 CPS score was higher in EBVaGC(P＜0.001),and the deletion rate of AR-ID1A expression was also higher in EBVaGC(P=0.012).But there was no significant difference,and so did not the expression level of HER2 between EBVaGC and non-EBVaGC.Survival a-nalysis revealed that positive/high expression of Claudin18.2 did not show a significant correlation with prognosis.Sperman corre-lation analysis indicated a positive correlation between Clau-din18.2 and PD-L1(r=0.338 4,P=0.016 2),while the ex-pression of Claudin18.2 was negatively correlated with ARID 1A(r=-0.354 5,P=0.011 5).Finally,there was no signifi-cant correlation between Claudin18.2 and HER2.Conclusion Claudin18.2 is highly expressed in EBVaGC,which is correla-ted with PD-L1 and ARID1A.It provides more options of combi-nation therapies for patients with advanced gastric cancer.

BACKGROUND: Intensive phototherapy (IPT) and exchange transfusion (ET) are the main treatments for extreme hyperbilirubinemia. However, there is no reliable evidence on determining the thresholds for these treatments. This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia. METHODS: This retrospective cohort study was conducted in seven centers from January 2015 to January 2018. Patients with extreme hyperbilirubinemia that met the criteria of ET were included. Patients were divided into three subgroups (low-, medium-, and high- risk) according to gestational week and risk factors. Propensity score matching (PSM) was performed to balance the data before treatment. Study outcomes included the development of bilirubin encephalopathy, duration of hospitalization, expenses, and complications. Mortality, auditory complications, seizures, enamel dysplasia, ocular motility disorders, athetosis, motor, and language development were evaluated during follow-up at age of 3 years. RESULTS: A total of 1164 patients were included in this study. After PSM, 296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-, medium-, and high-risk subgroups with 188, 364, and 40 matched patients, respectively. No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity, complications, and sequelae. Hospitalization duration and expenses were lower in the low- and medium-risk subgroups in the IPT only group. CONCLUSIONS In this study, our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia. The indication of ET for patients with hyperbilirubinemia could be stricter. However, it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors. If IPT can be guaranteed and proved to be therapeutic, ET should be avoided as much as possible.
