Objective:To identify the predictive validity of C-reactive protein to albumin ratio (CAR) in the early diagnosis of Kawasaki disease shock syndrome (KDSS).Methods:This was a retrospective case-control study.Children with KDSS hospitalized in the Children′s Hospital, Capital Institute of Pediatrics, from January 2019 to December 2022, were selected as the case group, and children with Kawasaki disease (KD) hospitalized in the same period were selected as the control group.After a 1︰4 propensity score matching (PSM) of age and gender, the demographic characteristics, laboratory and imaging examinations, and other clinical data of all the patients were analyzed and compared between the two groups.Multivariate Logistic regression was used to analyze the possible risk factors of KDSS.The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of risk factors for KDSS.Results:There were 45 KDSS children and 269 KD children included in the study.The KDSS patients were older than the KD patients at the onset [43(19, 51) months vs.24(14, 44) months, Z=2.791, P<0.05].After age- and gender-based PSM, there were 45 children in the KDSS group and 180 children in the KD group.The children with KDSS had a shorter duration of fever [6(4, 6) days vs.6(5, 7) days] and a higher risk of coronary artery lesions [42.22%(19/45) vs.25.56%(46/180)] compared to those with KD ( Z=2.184, χ2=4.868, all P<0.05).Multivariate Logistic regression analysis showed that CAR, neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, D-dimer, platelet count, serum sodium and estimated glomerular filtration rate were the independent risk factors for KDSS.The area under the ROC curve for identifying KDSS based on CAR was 0.850.When the cutoff value of CAR was 2.73, the sensitivity and specificity were 77.80% and 81.67%, respectively.After subgroup analysis, each one-unit increment in CAR was associated with a 239.6% increased risk of KDSS in children ≥ 3 years old ( OR=3.396, 95% CI: 2.105-5.479, P<0.05). Conclusions:As one of the independent risk factors for KDSS, CAR has high predictive value for early diagnosis of KDSS.In KD patients ≥ 3 years old, the risk of developing KDSS increases significantly with increased CAR.

A retrospective analysis was made on the clinical data and gene mutation characteristics of 2 children admitted to the Children′s Hospital of Zhejiang University School of Medicine for epilepsy without periventricular nodules caused by the ARF1 gene mutation from August 2023 to February 2024, and relevant literature was reviewed.Both patients presented with seizures and psychomotor retardation, and 1 of them was diagnosed with West syndrome.Whole exome sequencing confirmed that the 2 patients carried a missense mutation in the ARF1 gene (c.55C>A, p.R19S).Brain magnetic resonance imaging (MRI) of 2 patients revealed no obvious abnormalities.A summary analysis of 5 cases of ARF1 gene mutations reported in three foreign literatures showed that patients with ARF1 gene mutations usually presented with seizures, developmental delay, hypotonia, mental retardation, and motor stereotypies.MRI showed periventricular nodular heterotopia, corpus callosum dysplasia, subcortical white matter abnormalities, and delayed myelination.This study found for the first time that ARF1-related disorders can occur without significant brain structural malformations, indicating that there are inconsistencies in neuroimaging findings, adding valuable phenotypic information to this gene.The differences in imaging findings may be the result of genetic background or variation in ARF1-interacting proteins, or may be caused by altered regulatory mechanisms of protein activity.

Objective:To explore the implementation status and influencing factors of enhanced recovery after surgery (ERAS) in perioperative management of patients undergoing total hip arthroplasty.Methods:This study was a cross-sectional study. From May to December 2022, purposive sampling was used to select 186 orthopedic nurses from 9 ERAS pilot hospitals in Beijing as the research subject. A self-designed questionnaire was used to investigate the implementation status of ERAS. Pearson correlation was used to analyze the correlation between Nurse ERAS Implementation Status Questionnaire scores and ERAS Behavioral Intention Questionnaire scores. Multiple linear regression was used to analyze the influencing factors of ERAS in perioperative nursing of patients undergoing total hip arthroplasty.Results:A total of 186 questionnaires were distributed and 186 valid questionnaires were collected, with an effective response rate of 100.00% (186/186). The total score of the Nurse ERAS Implementation Status Questionnaire was (116.49±20.71), and the standardized scores for each dimension from high to low were follow-up management (80.22±20.44), intraoperative period (78.98±15.17), preoperative period (74.72±14.09), and postoperative period (69.77±15.94). The total score of the ERAS Behavioral Intention Questionnaire was (77.39±15.08), and the standardized scores of each dimension from high to low were subjective norm (79.93±19.01), behavioral intention (77.69±19.61), behavioral attitude (74.19±15.77), and perceived behavioral control (64.41±14.69). The nurse's professional title, familiarity with ERAS, ERAS training, and subjective norm were the influencing factors of the specific implementation status score of ERAS ( P<0.05), explaining 40.9% of the total variance. Conclusions:Nurses should strengthen training on ERAS, increase their familiarity with knowledge, and adopt various incentive measures to further enhance the implementation of ERAS programs in clinical practice.

Objective:To investigate the differences in estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2) and Ki-67 expressions between metastatic sites and primary sites in metastatic triple-negative breast cancer (TNBC) patients and to analyze their effects on the prognosis of patients.Methods:A retrospective cohort study was conducted. The clinicopathological data of 108 patients diagnosed with metastatic TNBC in Lianyungang Hospital Affiliated to Xuzhou Medical University from September 2018 to September 2023 were collected. Local metastatic sites included ipsilateral axillary lymph nodes and chest wall, while distant metastatic sites encompassed contralateral axillary lymph nodes and chest wall, bilateral supraclavicular lymph nodes, cervical lymph nodes, bone and viscera. The metastatic sites were identified as metastatic TNBC by using immunohistochemistry (IHC) and/or fluorescence in situ hybridization. The heterogeneity in ER, PR, HER2, and Ki-67 expression between primary sites and metastatic sites in all patients and those with local and distant metastases was analyzed, and the heterogeneity was defined as the inconsistency in the expression of markers including loss and gain expressions between primary sites and metastatic sites. The Kaplan-Meier method was used to analyze disease-free survival (DFS), and log-rank test was used for comparison among groups.Results:All patients were female, with an average age of (55±10) years; 51 cases had local metastases, and 57 cases had distant metastases. In metastatic sites, no ER and PR positivity were observed; in primary sites, 28.7% (31/108) of patients were ER positive and 21.3% (23/108) of patients were PR positive, and there were statistically significant differences in the proportion of patients with ER or PR positive between primary sites and metastatic sites (all P < 0.001). There were no statistically significant differences in the proportions of patients with different expression status including HER2 [positive: 0 (0/108) vs. 4.6%(5/108), low expression: 50.0% (54/108) vs. 45.4% (49/108), negative: 50.0% (54/108) vs. 50.0% (54/108)], Ki-67 [high expression: 86.1% (93/108) vs. 91.7% (99/108)] between metastatic sites and primary sites (all P > 0.05). The proportions of patients with inconsistent ER and PR expression between metastatic sites and primary sites were 28.7% (31/108) and 21.3% (23/108), respectively, all due to the expression loss in metastatic sites; the proportions of patients with inconsistent HER2 and Ki-67 expression between metastatic sites and primary sites were 42.6% (46/108) and 11.1% (12/108), respectively, with HER2 and Ki-67 expression loss of metastatic sites accounting for 22.2% (24/108) and 8.3% (9/108), respectively and expression gain accounting for 20.4% (22/108) and 2.8% (3/108), respectively. The proportions of patients with inconsistent ER [45.6% (26/57) vs. 9.8% (5/51)], PR [36.8% (21/57) vs. 3.9% (2/51)] and Ki-67 [17.5% (10/57) vs. 3.9% (2/51)] expression in distant metastatic sites and primary sites were higher than those with local metastatic sites and primary sites, and the differences were statistically significant (all P < 0.05). The proportions of patients with inconsistent HER2 between distant metastatic sites and primary sites and those with inconsistent HER2 between local metastatic sites and primary sites were 47.4% (27/57), 37.3% (19/51), respectively, and the difference was not statistically significant ( P = 0.300). Patients with inconsistent ER and Ki-67 expressions had better DFS than those with consistent expressions, with median DFS time of 30 months (95% CI: 22-40 months) vs. 22 months (95% CI: 22-24 months) for ER and 28 months (95% CI: 20-61 months) vs. 22 months (95% CI: 22-24 months) for Ki-67, and the differences were statistically significant (all P < 0.05). There were no significant differences in DFS between metastatic sites and primary sites with consistent expressions of PR and HER2 or not (all P > 0.05). Conclusions:There are differences in ER and PR expressions between primary sites and metastatic sites of metastatic TNBC patients, while the expressions of HER2 and Ki-67 seem to be no differences. The inconsistency of ER, PR and Ki-67 expressions with primary sites in distant metastatic sites are more common compared with in local metastatic sites. The differences in hormone receptor expression between primary sites and metastatic sites may impact patients' DFS.

Objective:To explore the clinical effectiveness of hemostatic bandage on wound safety and comfort after transradial coronary angiography and/or interventional therapy.Methods:This was a experimental study. A total of 400 consecutive patients who underwent transradial coronary angiography and/or interventional therapy in the Department of Cardiology, Peking University Third Hospital from July to October 2022 were enrolled and randomly divided into the hemostatic bandage group and the hemostatic balloon compressor group by the envelope method with 200 cases in each group. The hemostatic bandage group and the hemostatic balloon compressor group were treated with hemostatic bandage and hemostatic balloon compressor as transradial artery hemostatic device, respectively, to observe and compare postoperative hemostatic effect, hemostat use time, complication rate, postoperative pain, the degree of numbness in the finger on the operated side and wristband comfort between the two groups.Results:The hemostatic success rate was 98.5% (197/200) and 99.0% (198/200) in the hemostatic bandage and the hemostatic balloon compressor group, respectively, with no statistical difference ( χ2=0.20, P>0.05). The hemostat use time in the hemostatic bandage group and the hemostatic balloon compressor group was (6.23 ± 0.47) h and (17.01 ± 7.74) h, respectively, and the difference was statistically significant ( t=-19.66, P<0.01). The incidence of complications in the hemostatic bandage group and the hemostatic balloon compressor group was 13.5%(27/200) and 29.5%(59/200), respectively, and the difference was statistically significant ( χ2=8.01, P<0.05). Among the complications, swelling occurred in 21 individuals of the hemostatic bandage group and 54 individuals of the hemostatic balloon compressor group with statistically significant differences ( U=16 689.50, P<0.01). Besides, the hemostatic bandage group was significantly better than the hemostatic balloon compressor group with statistically significant differences in wound pain at immediate postoperative ( U=13 669.50, P<0.01), in finger numbness at immediate postoperative and 1-hour postoperative (immediate postoperative: U=17 838.00, P<0.05; 1-hour postoperative: U=13 342.50, P<0.01), in comfort at immediate postoperative, 4-hours, 8-hours and 12-hour postoperative(immediate postoperative: U=9 966.50, P<0.01; 4-hour postoperative: U=12 851, P<0.01; 8-hour postoperative: U=14 900, P<0.01; 12-hour postoperative: U=15 920, P<0.01). Conclusions:The hemostatic bandage shows better hemostatic effect, shorter compression time, lower complication rate, less wound pain, less numbness of the finger on the operation side, and higher comfort of the wrist band compared to hemostatic balloon compressor after transradial coronary angiography and/or interventional therapy, which is worthy of clinical promotion.

Neurogenesis decline in hippocampal dentate gyrus (DG) participates in stress-induced depressive-like behaviors, but the underlying mechanism remains poorly understood. Here, we observed low-expression of NOD-like receptor family pyrin domain containing 6 (NLRP6) in hippocampus of stress-stimulated mice, being consistent with high corticosterone level. NLRP6 was found to be abundantly expressed in neural stem cells (NSCs) of DG. Both Nlrp6 knockout (Nlrp6^-/-) and NSC-conditional Nlrp6 knockout (Nlrp6CKO) mice were susceptible to stress, being more likely to develop depressive-like behaviors. Interestingly, NLRP6 was required for NSC proliferation in sustaining hippocampal neurogenesis and reinforcing stress resilience during growing up. Nlrp6 deficiency promoted esophageal cancer-related gene 4 (ECRG4) expression and caused mitochondrial dysfunction. Corticosterone as a stress factor significantly down-regulated NLRP6 expression, damaged mitochondrial function and suppressed cell proliferation in NSCs, which were blocked by Nlrp6 overexpression. ECRG4 knockdown reversed corticosterone-induced NSC mitochondrial function and cell proliferation disorders. Pioglitazone, a well-known clinical drug, up-regulated NLRP6 expression to inhibit ECRG4 expression in its protection against corticosterone-induced NSC mitochondrial dysfunction and proliferation restriction. In conclusion, this study demonstrates that NLRP6 is essential to maintain mitochondrial homeostasis and proliferation in NSCs, and identifies NLRP6 as a promising therapeutic target for hippocampal neurogenesis decline linked to depression.

Objective:To explore the evaluation of nursing undergraduates on the effect of ideological and political teaching in nursing research courses.Methods:Using the purposive sampling method, a total of 19 undergraduate students from School of Nursing at Peking University who participated in nursing research ideological and political education courses were selected for face-to-face semi-structured interviews from March to June 2022. The interview data was analyzed using the Colaizzi phenomenological data analysis method.Results:A total of 19 students were interviewed, and the interviewees stated that through the study of nursing research ideological and political teaching courses, they had mastered scientific research methods, cultivated scientific thinking, strengthened innovation consciousness, expanded international vision and enhanced professional identity.Conclusions:This study is a beneficial attempt at ideological and political education in nursing research courses, providing a basis for the design, implementation and evaluation of ideological and political teaching of similar courses in the future.

School-age children are in a specific development stage corresponding to juvenility, when the white matter of the brain experiences ongoing maturation. Diffusion-weighted magnetic resonance imaging (DWI), especially diffusion tensor imaging (DTI), is extensively used to characterize the maturation by assessing white matter properties in vivo. In the analysis of DWI data, spatial normalization is crucial for conducting inter-subject analyses or linking the individual space with the reference space. Using tensor-based registration with an appropriate diffusion tensor template presents high accuracy regarding spatial normalization. However, there is a lack of a standardized diffusion tensor template dedicated to school-age children with ongoing brain development. Here, we established the school-age children diffusion tensor (SACT) template by optimizing tensor reorientation on high-quality DTI data from a large sample of cognitively normal participants aged 6-12 years. With an age-balanced design, the SACT template represented the entire age range well by showing high similarity to the age-specific templates. Compared with the tensor template of adults, the SACT template revealed significantly higher spatial normalization accuracy and inter-subject coherence upon evaluation of subjects in two different datasets of school-age children. A practical application regarding the age associations with the normalized DTI-derived data was conducted to further compare the SACT template and the adult template. Although similar spatial patterns were found, the SACT template showed significant effects on the distributions of the statistical results, which may be related to the performance of spatial normalization. Looking forward, the SACT template could contribute to future studies of white matter development in both healthy and clinical populations. The SACT template is publicly available now ( https://figshare.com/articles/dataset/SACT_template/14071283 ).

Objective:To investigate the effects of different intensity of lighting on normal refractive development and form deprivation myopia (FDM) in guinea pigs.Methods:A total of 108 healthy 3-week-old guinea pigs were divided into normal refractive development guinea pigs ( n=54) and FDM guinea pigs ( n=54). FDM models were prepared in FDM animals by occlusion of the left eyes using an opaque mask, and the bilateral eyes were open in the normal refractive development guinea pigs.The guinea pigs were randomized to low (20 lx), normal(300 lx), and high intensity-lighting (5 000 lx) groups with a 12-hour light/12-hour dark cycle for 6 consecutive weeks under LED light.The ocular biometry was performed in a two-week interval.Axial length (AL) and dilated diopter were measured by A-scan ultrasonography and retinoscopy, respectively, and were compared after different lighting durations, and the change trends of them in normal refractive development and FDM guinea pigs were evaluated. Results:The AL values were not significantly different among low, normal and high intensity-lighting groups ( Fgroup=0.365, P=0.697), and the AL was gradually prolonged over the lighting duration ( Ftime=353.750, P<0.001). The diopters showed a statistically significant difference among different intensity-lighting groups ( Fgroup=3.576, P=0.034). The diopter in high intensity-lighting for 4 weeks was (+ 2.75±2.15) D, which was significantly higher than (0.41±3.07) D in the normal refrective development guinea pigs ( P<0.001). In the FDM guinea pigs, both AL and diopter were not significantly different among low, normal and high intensity-lighting groups ( Fgroup=0.105, P=0.900; Fgroup=0.973, P=0.387), and significant differences were seen in AL and diopter among three groups ( Ftime=408.302, 27.407; both at P<0.001). The diopter in FDM eyes of low intensity-lighting for 2 weeks was (+ 2.35±1.95) D, which was higher than (+ 1.90±0.97) D before lighting, with no statistically significant difference between them ( P>0.05). The AL was shortest and the AL change was smallest in normal refractive development guinea pigs of high intensity-lighting group.The diopter change in FDM guinea pigs of the low intensity-lighting group was significantly smaller than that in the normal intensity-lighting group ( P<0.001), with a transient hyperopia drift. Conclusions:The 5 000 lx lighting can slow down the development toward myopia in the normal refractive development eyes, and 20 lx lighting tends to delay the progression FDM eyes with a hyperopic shift after lighting for 2 weeks.

Objective:To investigate the clinicopathological features,differential diagnosis,treatment and prognosis of Burkitt-like lymphoma with 11q aberration (BLL-11q).Methods:The clinical manifestations,histological morphology,immunophenotype and molecular genetic changes of 2 cases of BLL-11q admitted to the department of pathology of The First People's Hospital of Lianyungang in 2020 and 2021 were analyzed retrospectively,and the relevant literatures were reviewed.Results:Patients were found with right neck masses inadvertently and grew rapidly. They presented with localized disease with Ann Arbor stages IA and IIA. Microscopically, the normal structure of the lymph node disappeared and was replaced by a diffuse proliferation of lymphocytes, with consistent morphology and medium size. And the presence of "star-sky" phenomenon was obvious, the morphological characteristics were similar to Burkitt lymphoma. Immunophenotypically, tumor cells were diffusely positive for CD20, CD79α, PAX5, CD10 and Bcl-6, partly moderately positive for C-MYC and MUM-1, however, CD3, Bcl-2, CD30 and TDT were negative,Ki-67 positive index was more than 95%, and EBER was negative. FISH detection showed that MYC, Bcl-2, and Bcl-6 were negative. Both cases had the 11q23.3 gain and 11q24.3 loss. Both patients were treated with chemotherapy and followed up for 10-22 months,and achieved complete remission and disease-free survival.Conclusion:BLL-11q is a rare germinal center B-cell lymphoma with abnormal long arm of chromosome 11 and lack of MYC gene rearrangement. It should be distinguished from Burkitt lymphoma, diffuse large B-cell lymphoma, B-lymphoblastic lymphoma, large B-cell lymphoma with IRF4 rearrangement and high-grade B-cell lymphoma. On the basis of morphology and immunophenotype, the diagnosis depends on genetic detection. There may be a better prognosis.
