Objective:To investigate the current status of clinical leadership among Interventional Operating Room nurses in Shandong Province and to analyze its influencing factors.Methods:In December 2024, 220 Interventional Operating Room nurses from 46 ClassⅢ Grade A general hospitals in Shandong Province were selected for a cross-sectional survey using convenience sampling. General Information Questionnaire, Clinical Leadership Survey, Chinese version of Wong and Law Emotional Intelligence Scale (WLEIS-C) , and Jefferson Scale of Empathy-Health Professionals (JSE-HP) were used as survey instruments. Multiple linear regression was used to analyze the factors influencing clinical leadership among Interventional Operating Room nurses. Pearson correlation analysis was used to explore the relationship between emotional intelligence, empathy, and clinical leadership.Results:A total of 220 questionnaires were distributed and 204 valid questionnaires were recovered, with a valid recovery rate of 92.73% (204/220) . The clinical leadership scores of the 204 Interventional Operating Room nurses were (66.35±8.74) , and the dimensions scored, in descending order, as encouraging the heart, enabling others to act, modeling the way, inspiring a shared vision, and challenging the process. The mean scores of WLEIS-C and JSE-HP items were (5.88±0.90) and (4.61±0.63) , respectively. Multiple linear regression analysis showed that the nature of employment and whether or not they participated in leadership training were influencing factors for clinical leadership among Interventional Operating Room nurses (partial regression coefficients of -2.831 and -2.999, respectively; P<0.05) . Emotional intelligence and empathy ability among Interventional Operating Room nurses were positively correlated with clinical leadership ( P<0.05) . Conclusions:Clinical leadership of nurses in the Interventional Operating Room of ClassⅢ Grade A general hospitals in Shandong Province is at a moderate to high level. Nurses who participate in leadership training, have staffing, have greater empathy, and have higher emotional intelligence have greater clinical leadership. It is recommended that nursing administrators add leadership-related courses to the training of nurses in the Interventional Operating Room, and take steps to improve nurses' emotional intelligence and empathy ability, thereby promoting clinical leadership among Interventional Operating Room nurses.

Objective To investigate the alleviation of Nippostrongylus brasiliensis infection on dextran sulfate sodium salt (DSS)-induced ulcerative colitis in mice, and to explore the underlying mechanism. Methods Thirty male C57BL/6J mice of the SPF grade, each weighing approximately 25 g, were randomly divided into three groups, including the blank control group (NC group), DSS modeling group (DSS group), and N. brasiliensis treatment group (Nb + DSS group), of 10 mice in each group. Mice in the DSS group were orally administered with 3.5% DSS daily since day 1 (D0) for 6 successive days, and given normal drinking water since D6, and animals in the Nb + DSS group were subcutaneously injected with the third-stage larvae of N. brasiliensis at a dose of 500 larvae per mice 5 days prior to D0, followed by oral administration with 3.5% DSS daily since D0 for 6 successive days and normal drinking water since D6, while mice in the NC group were given normal drinking water. Mouse body weight and stool were observed and the disease activity index (DAI) was scored in each group during the study period. All mice were sacrificed on D9. The mouse colon length was measured, and mouse colon specimens were subjected to hematoxylin-eosin (HE) staining and histopathological scoring. In addition, the mRNA and protein expression of interleukin (IL)-1β and IL-10 was quantified in mouse colon specimens using quantitative fluorescent real-time PCR (qPCR) assay and enzyme-linked immunosorbent assay (ELISA), and the mRNA and protein expression of mucosal repair-associated molecules zonula occludens-1 (ZO-1), mucin 2 (MUC2) and claudin-1 was detected in mouse colon specimens using qPCR assay and immunofluorescence assay. Results The mice body weights, DAI scores and colon lengths were (26.26 ± 1.93), (22.39 ± 1.65), (25.00 ± 1.58) g (F = 8.06, P < 0.01); (1.89 ± 0.34), (0.47 ± 0.39), 0 points (F = 57.61, P < 0.000 1); and (42.50 ± 5.75), (56.20 ± 5.96) mm and (61.17 ± 7.88) mm (F = 13.72, P < 0.001) in the NC, DSS and Nb + DSS groups on D9, respectively, and elevated mouse body weight (P < 0.05), reduced DAI score (P < 0.000 1) and increased colon length (P < 0.01) were observed in the Nb + DSS group relative to the DSS group on D9. Pathological examinations showed that the colonic crypts were relatively intact and the inflammatory cell infiltration was lower in the mouse colon specimens in the Nb + DSS group than in DSS the group. There was a significant difference in the histopathological scores of mouse colon specimens among the NC group (0 point), the DSS group [(2.00 ± 1.22) points] and the Nb + DSS group [(0.20 ± 0.45) points] (F = 10.71, P < 0.01), respectively, and the histopathological score of mouse colon specimens was significantly higher in the DSS group than in the NC and Nb + DSS groups (both P values < 0.01). qPCR assay quantified that the relative IL-10 and IL-1β mRNA expression was 1.25 ± 0.08, 0.44 ± 0.14 and 1.30 ± 0.45 (F = 10.66, P < 0.01), and 0.22 ± 0.13, 1.14 ± 0.31 and 0.41 ± 0.19 (F = 16.89, P < 0.001) in mouse colon specimens in the NC, DSS and Nb + DSS groups, respectively, and higher IL-10 mRNA expression and lower IL-1β mRNA expression were found in mouse colon specimens in the Nb + DSS group than in the DSS group (both P values < 0.01). The relative MUC2, claudin-1 and ZO-1 mRNA expression was 0.87 ± 0.25, 0.34 ± 0.26 and 4.21 ± 0.55 (F = 121.60, P < 0.000 1), 1.05 ± 0.41, 0.16 ± 0.09 and 0.22 ± 0.11 (F = 14.00, P < 0.01), and 1.03 ± 0.10, 0.60 ± 0.11 and 1.64 ± 0.28 (F = 32.16, P < 0.000 1) in mouse colon specimens in the NC, DSS and Nb + DSS groups, respectively, and significantly higher MUC2 and ZO-1 mRNA expression was quantified in mouse colon specimens in the Nb + DSS group than in the DSS group (both P values < 0.05). The mean fluorescence intensities of ZO-1 and claudin-1 were 17.18 ± 2.08, 12.38 ± 1.21 and 18.06 ± 2.59 (F = 8.95, P < 0.01) and 13.50 ± 1.63, 9.66 ± 2.03 and 13.61 ± 0.97 (F = 6.96, P < 0.05) in mouse colon specimens in the NC, DSS and Nb + DSS groups, respectively, and the mean fluorescence intensities of ZO-1 and claudin-1 were significantly greater in mouse colon specimens in the Nb + DSS group than in the DSS group (both P values < 0.05). Conclusion N. brasiliensis infection may remarkably alleviate DSS-induced ulcerative colitis in mice through promoting expression of anti-inflammatory cytokines, inhibiting expression of pro-inflammatory cytokines and facilitating mucosal repair in colon tissues.

Objective The aim of this study was to investigate the impact and mechanisms of emodin on oxidative stress response in lipopolysaccharide(LPS)-induced murine mononuclear macrophages(RAW264.7).Methods Involved the use of LPS,RAW264.7 cells,and emodin.Experimental groups included a control group,LPS(1 μg/mL)group,and LPS(1 μg/mL)+emodin(15 μmmol/L)pretreatment group.Aldehyde malondialdehyde(MDA)content,intracellular reactive oxygen species(ROS)levels,and silent information regulator 2(Sirt2)expression were evaluated at 6,12,and 18 hours after LPS exposure.Additionally,RAW264.7 cells were pretreated with Sirt2 inhibitor AGK2(20 μmol/L)followed by LPS stimulation,and the above-mentioned parameters were assessed at 6 hours.Results Compared to the control group,MDA content,ROS levels,Sirt2 mRNA,and protein expression in RAW264.7 cells in the LPS group increased at all time points(all P<0.05).At 6 and 18 hours,MDA content and ROS levels in RAW264.7 cells in the LPS+emodin group decreased significantly(all P<0.05),while at 12 hours,ROS levels were lower in the LPS group compared to the LPS+emodin group(P<0.05).Sirt2 mRNA and protein levels significantly increased at all time points(all P<0.05)compared to the LPS group.In the LPS+emodin+AGK2 group,Sirt2 mRNA and protein levels decreased,and MDA content and ROS levels increased compared to the LPS+emodin group(all P<0.05).Conclusion LPS-induced oxidative stress in RAW264.7 cells and emodin attenuate LPS-induced oxidative stress in RAW264.7 cells through Sirt2.

【Objective】 To explore the effect and mechanism of Fasudil in the treatment of experimental autoimmune myocarditis (EAM) in mice so as to provide a theoretical basis for the clinical use of Fasudil in treating myocarditis. 【Methods】 Balb/c male mice were used as the research objects, and the EAM mice model was constructed using MyHC-α614-629 polypeptide. Mononuclear cells were isolated and cultured to detect the number of mononuclear cells in mouse spleen. Inflammation infiltration, fibrosis and IL-6 expression in mouse myocardial tissue were detected by HE staining, Masson staining and immunohistochemistry, respectively. The protein expressions of Notch1 and IL-6 were detected by Western blotting. qRT-PCR was used to detect the expressions of pro-inflammatory factors (IL-1α, IL-1β and IL-6) as well as key genes of TLRs and NOTCH signaling pathway. 【Results】 EAM mice showed increased HW, decreased BW, increased HW/e-BW, and increased inflammatory infiltration and fibrosis in myocardial tissue. The above-mentioned symptoms or pathological features were improved in EAM mice treated with Fasudil. The analysis showed that the pro-inflammatory factors IL-1α, IL-1β and IL-6 in the myocardial tissue of EAM mice were significantly increased, but only the expression of IL-6 was statistically different after Fasudil treatment compared with the control group. In addition, TLRs signaling pathway might also play an important role in the EAM mice treated with Fasudil. The expressions of IL-6 and Notch1 were consistent, and the expressions of the key genes of NOTCH signaling pathway (Notch1, Hes1 and Jag2) were down-regulated after Fasudil treatment. 【Conclusion】 Fasudil exerts a protective effect on down-regulation of IL-6 expression by inhibiting the NOTCH signaling pathway in EAM mice.

Objective:To study the clinical and genetic characteristics of Wiskott-Aldrich syndrome (WAS) in neonates.Methods:From January 2016 to August 2022, neonates with WAS admitted to the neonatal department of our hospital were studied.Their clinical features, laboratory findings, genetic characteristics and clinical outcomes were retrospectively analyzed.Results:A total of 11 neonates(all male) were included. The mothers of 3 neonates had thrombocytopenia during pregnancy. The presenting symptoms included isolated bloody stool (4 cases), jaundice (3 cases), bloody stool with petechiae, bloody stool with hematemesis, cough and fever(1 case each). Eczema appeared from 6 d to 3 months after birth and in 6 cases during the neonatal period. None of the 11 cases had serious infection during the neonatal period. 9 cases had infection from 8 d to 5 months and 2 cases had not been infected until the last follow-up. Genetic sequencing showed four frameshift variants(c.30dupC, c.205dupT, c.1340_1343dupC and c.673_674delA), four nonsense variants(c.37C>T, c.295C>T, c.889C>T and c.823G>T) and three missense variants(c.134C>T, c.397G>A and c.341T>C). Pedigree verification of variants found 10 cases were inherited from their mothers and 1 case was de novo variant.Conclusions:WAS is characterized by bloody stool and eczema in the neonatal period, mostly without serious infections and lacking specific manifestations. Genetic screening for early identification of unexplained thrombocytopenia in male newborns should be performed as early as possible.

Objective:To study the clinical and laboratory characteristics of neonatal isolated sulfite oxidase deficiency (ISOD).Methods:An infant with neonatal ISOD admitted to our hospital was retrospectively analyzed. Using key words "isolated sulfite oxidase deficiency", "SUOX gene", "Infant, newborn", databases including CNKI, Wanfang database, National library and literature center of science and technology, China science paper online, PubMed, Web of Science and EMBASE (up to January 2021) were searched and literature review was conducted. The clinical manifestations, laboratory results, treatment and prognosis were analyzed.Results:Our patient was a full-term male infant with eye movement disorder, refractory seizures, feeding difficulties, increased muscle tone, developmental retardation and microcephaly. Urine sulfite paper-strip test was positive. Uric acid was normal. Whole exon sequencing (WES) revealed SUOX c.475G>T and c.1201A>G compound heterozygous mutations. Cranial MRI showed multiple encephalomalacia and brain atrophy at 5-month of age. The infant died at 8-month. In the literature review, a total of 29 articles and 32 cases of neonatal ISOD were found. 87.5% of the cases developed symptoms within 1-week after birth. All had convulsive seizures. Some of them had feeding difficulties, muscle tone changes, developmental retardation, microcephaly and ectopia lentis. Cranial imaging showed white matter cystic lesions and brain atrophy. Laboratory examination showed elevated urinary sulfite and S-sulfocysteine. Uric acid and xanthine/hypoxanthine were normal. Blood homocysteine was decreased. 23 cases received genetic testing and all of them had SUOX mutations. The treatment was mainly symptomatic relief and supportive treatment. During follow-up, 15 cases died, 13 cases survived and 4 cases were unknown. All the surviving children had drug-resistant convulsions and developmental retardation.Conclusions:Neonatal ISOD may present with refractory convulsions, feeding difficulties and developmental retardation. Cystic white matter changes and brain atrophy may be seen on cranial imaging. Elevated urinary sulfites, decreased blood homocysteine and normal uric acid are important clues for diagnosis. Genetic testing is helpful for early diagnosis.

OBJECTIVE: To analyze the clinical features, biochemical characteristics and molecular pathogenesis of a girl with isovaleric acidemia. METHODS: Clinical features, blood spot amino acid profiles and urinary organic acid profiles of the patient were analyzed. Targeted capture, next generation sequencing and Sanger sequencing were carried out to detect potential variant of the IVD gene. RESULTS: The patient presented with poor weight gain, poor feeding, lethargy, and a "sweaty feet" odor 10 days after birth. Biochemical test suggested hyperammonemia. Blood spot amino acid profiles displayed a dramatic increase in isovalerylcarnitine (C5: 3. 044, reference range 0.04 - 0.4 μmol/L). Organic acid analysis of her urine sample revealed a high level of isovaleric glycine (669. 53, reference range 0 - 0.5). The child was ultimately diagnosed with isovaleric acidemia, and was found to harbor a paternally derived heterozygous variant c.149G>A (p.R50H) and a maternally derived heterozygous variant c.1123G>A (p.G375S) of the IVD gene. Her elder brother was a heterozygous carrier of c.1123G>A (p.G375S) variant. The c.149G>A (p.R50H) was a known pathogenic variant, while the c.1123G>A (p.G375S) variant was previously unreported. CONCLUSION The pathogenesis of the patient was delineated from the perspective of genetics, which has provided a basis for clinical diagnosis, treatment as well as genetic counseling.

To investigate the effects of ()infection on autonomic nervous function and calcitonin gene-related peptide in patients with functional dyspepsia(FD). Thirty-one patients with FD matching Rome Ⅳ criteria were included and divided into -positive group and -negative group.All patients were evaluated by Symptom Index of Dyspepsia(SID),Nepean Dyspepsia Index(NDI),and Hospital Anxiety and Depression Scale(HADS).Their heart rate variability(HRV)and calcitonin gene-related peptide(CGRP)level were also measured. There were no significant differences in SID(=-0.858, =0.858),NDI(=-1.464, =0.143),and Hospital Depression Scale score(=0.699, =0.485).However,the Hospital Anxiety Scale score was significantly higher in -positive group than the -negative group(=-2.470, =0.014).The level of CGRP in -positive group[(0.999±0.274)ng/ml]was significantly higher than that in the -negative group[(0.812±0.172)ng/ml;=2.238, =0.033].HRV data showed no significant difference between these two groups at very low frequency(=-1.210, =0.236),low frequency(LF)(=0.419, =0.678),high frequency(HF)(=0.612, =0.546),LF/HF(=-0.882, =0.399),and total power(=-0.963, =0.344). In FD patients,patients with -positive FD patients have higher depression and CGRP levels than those without infection,although their dyspepsia symptoms and HRV show no notable changes.
