Objective To explore the expression level of visceral adipose tissue-derived serine protease inhibitor(Vaspin)and secreted frizzled-related protein5(SFRP5)in the serum of children with idiopathic short stature(ISS)and its diagnostic value.Methods 70 children with ISS diagnosed in the First Hospital of Zhangjiakou from December 2021 to February 2023 were selected as the disease group,while 72 healthy volunteer children who underwent physical examination were collected as the control group.Immunoluminescence was applied to detect the expression level of VASPIN,Enzyme-linked immunosorbent assay(ELISA)was applied to detect the expression level of SFRP5 the clinical data of children in two groups were analyzed.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum Vaspin and SFRP5 for ISS,multivariate Logistic regression was used to analyze the influencing factors of ISS.Results Compared with the control group,the serum Vaspin level in the disease group was obviously increased(2.89±0.92 ng/ml vs 1.81±0.42 ng/ml),while the SFRP5 level was obviously reduced(10.22±2.84 pg/ml vs 13.21±3.53 pg/ml),the differences were statistically significant(t=9.040,5.552,all P＜0.05).The weight,height,body mass index(BMI)and proportion of sexual development stage II～V of children in the disease group were obviously lower than those in the control group,and the differences were statistically significant(t=7.687,6.330,5.559,7.024,all P＜0.05).The area under ROC curve showed that the AUC of Vaspin and SFRP5 and their combined detection in the diagnosis of ISS were 0.768,0.849 and 0.925,respectively,the combined diagnosis efficacy of Vaspin and SFRP5 was better than that of serum Vaspin and SFRP5 alone(Z =3.829,P＜0.001;Z =2.141,P=0.032).Multivariate Logistic regression analysis showed that BMI(OR=0.508,95%CI:0.260～0.991),Vaspin(OR=3.458,95%CI:1.125～10.631)and SFRP5(OR=0.378,95%CI:0.153～0.935)were the influencing factors for ISS(all P＜0.05).Conclusion The expression level of Vaspin in the serum of children with ISS is obviously increased,while the expression level of SFRP5 is obviously reduced.The two are influencing factors of ISS,and the combined detection of their expression levels has certain value in the diagnosis of ISS.

Objective:To investigate the effect of transurethral green laser prostate enucleation (GreenLEP) in the treatment of benign prostate hyperplasia (BPH) with detrusor underactivity (DU).Methods:The clinical data of 157 BPH patients treated with GreenLEP at Zhejiang Provincial People's Hospital from June 2019 to June 2020 were retrospectively analysed. The average age of the patients was (73.2±7.9) years old, with disease duration of 4(2, 8) years. Prior to surgery, all patients underwent comprehensive urodynamic studies and prostate ultrasonography (or enhanced MRI). Preoperative prostate volume was 42.1(34.2, 59.4) ml, international prostate symptom score (IPSS) was (27.9±3.4), quality of life (QOL) score was (5.1±0.8), preoperative residual urine volume (PVR) was 40.0(20.0, 80.0) ml, and preoperative maximum urinary flow rate (Q max) was 4.0(2.0, 7.0) ml/s. Patients were stratified into DU and non-DU groups using a bladder contractility index (BCI) threshold of less than 100 to diagnose DU. The cohort comprised 76 individuals in the DU group and 81 in the non-DU group. At the three-month postoperative juncture, a follow-up assessment was conducted on the patients, focusing on the evolution of subjective metrics (IPSS, QOL) and objective parameters (PVR, Q max). This study defined successful treatment outcomes at the 3-month mark as achieving PVR<20 ml and Q max>10 ml/s. Cases not meeting these criteria were categorized as treatment failure. Based on treatment outcomes, receiver operator characteristic (ROC) curve were plotted to identify the optimal cutoff value of BCI for predicting treatment efficacy. Subsequently, DU patients were classified into mild and severe DU groups based on this optimal BCI threshold. The differences of subjective indicators (IPSS, QOL) and objective parameters (PVR, Q max) preoperatively among non-DU, mild DU, and severe DU groups, as well as changes in these indices three months postoperatively were analyzed. Results:All 157 surgeries were successfully completed, with a median hospital stay of 6(5, 8) days. At the 3-month postoperative follow-up, 78 patients were deemed treatment successes and 3 as failures in non-DU group, 64 were successful and 12 failed in DU group. Utilizing ROC curve analysis, the BCI was optimally set at 57.5. This stratification resulted in 56 cases classified as mild DU (57.5≤BCI<100) group and 20 cases as severe DU (BCI<57.5) group. A comparative analysis of the three patient cohorts, revealed no significant statistical variation in terms of age, disease duration, or prostate volume ( P>0.05). In the non-DU, mild DU, and severe DU groups, IPSS were (26.8±3.4), (28.6±3.0), and (30.6±2.4) respectively, QOL sores were (4.9±0.9), (5.2±0.7), and (5.7±0.5) respectively, PVR volumes were 50.0(20.0, 90.0), 20.0(10.0, 50.0), and 60.0(27.5, 165.0) ml respectively, Q max were 4.0(2.0, 7.0), 5.0(4.0, 6.0), and 0(0, 2.3) ml/s respectively. Preoperative IPSS and QOL were significantly lower in the non-DU group compared with mild and severe DU groups ( P<0.05). Mild DU group had lower preoperative IPSS and QOL than the severe DU group ( P<0.05). Preoperative PVR in the mild DU group was less than that in both non-DU and severe DU groups ( P<0.05), but there was no statistically significant difference in preoperative PVR between non-DU and severe DU groups ( P>0.05). Preoperative Q maxof non-DU and mild DU groups was significantly higher than that of severe DU group ( P<0.05), with no significant difference between non-DU and mild DU ( P>0.05). Three months after surgery, IPSS scores of non-DU group, mild DU group and severe DU group were (12.5±4.7), (14.9±3.6) and (18.8±4.1), respectively. QOL scores of the 3 groups improved to (1.1±0.4), (1.2±0.5) and (1.9±1.0), respectively. PVR was 0 in non-DU and mild DU, and 20.0 (19.5, 61.3) ml in severe DU. Q max of the 3 groups were improved to 22.0(18.0, 27.0), 17.0(14.0, 22.3), and 9.0(6.8, 13.0) ml/s, respectively. Significant improvements of subjective symptoms (IPSS, QOL) and objective parameters (PVR, Q max) were observed in non-DU and mild DU group compared with preoperative( P<0.05). Significant improvements of IPSS, QOL and Q max ( P<0.05) but not PVR ( P=0.14)were observed in severe DU group. Additionally, significant differences were noted in PVR and Q max changes among the three groups ( P<0.05), but not in IPSS and QOL changes ( P>0.05). The absolute value of PVR and Q max changes in the non-DU group were higher than those in the mild DU group and the severe DU group ( P<0.05). Additionally, the change of Q max in mild DU group was significantly higher than that in severe DU group ( P<0.05). Conclusions:BPH patients with different degrees of DU can benefit from GreenLEP surgery, but for BPH patients with severe DU (BCI < 57.5), the improvements in PVR and Q max are less than that in the non-DU group.

Purpose To investigate the value of MYB and Notch1 immunohistochemical staining in the differential diagno-sis of classic adenoid cystic carcinoma of the breast(C-AdCC)and solid-basaloid adenoid cystic carcinoma of the breast(SB-AdCC).Methods MYB and Notch1 immunohistochemical staining were performed in 20 cases of C-AdCC,6 cases of SB-AdCC and 65 cases of other breast lesions in the archives of pa-thology department.26 cases of AdCC were detected by FISH,and 6 cases of SB-AdCC were detected by NGS.Results MYB immunohistochemical staining showed that C-AdCC(20/20)was moderately or strongly positive,while SB-AdCC(4/6)was mod-erately or strongly positive.Collagenous spherulosis(5/5)showed focal or diffuse weak positivity;Malignant adenomyoepi-thelioma(3/3)was focally moderately or strongly positive;8 matrix-producing carcinomas and 9 secretory carcinomas and 40 non-specific triple-negative breast cancers were negative.Immu-nohistochemistry of Notch1 showed diffuse moderate positive for SB-AdCC(3/6)and negative for C-AdCC(20/20).3 cases of malignant adenomyoepithelioma,5 cases of collagenous spherulo-sis,8 cases of matrix-producing carcinoma,9 cases of secretory carcinoma and 40 cases of non-specific triple-negative breast cancer were negative.FISH showed MYB gene disruption in C-AdCC(12/19)and NGS showed SB-AdCC(3/6)Notch1 muta-tion.Conclusion Moderately or strongly diffuse expression of MYB and Notch1 by immunohistochemistry can assist in the dif-ferentiation of C-AdCC from SB-AdCC,and it can be further clarified by molecular detection when it is difficult to distinguish malignant adenomyoepithelioma.

Objective:To explore the mediating effect of psychological resilience between structural empowerment and work engagement of clinical nurses.Methods:This study was a cross-sectional study. Using the convenient sampling method, a total of 1 723 nurses from three Class Ⅲ Grade A hospitals in Henan Province were selected as the research objects from March to May 2023. The survey was conducted using general information questionnaire, Conditions of Work Effectiveness Questionnaire-Ⅱ (CWEQ-Ⅱ), Nurses Psychological Resilience Scale and Utrecht Work Engagement Scale (UWES). Pearson correlation analysis was used to explore the correlation between structural empowerment, psychological resilience and job engagement. AMOS 24.0 software was used to establish the structural equation model and analyze the mediating effect.Results:A total of 1 723 questionnaires were sent out in this study, and 1 590 were effectively collected, with an effective recovery rate of 92.28%. The total scores of structural empowerment, psychological resilience and job engagement of 1 590 clinical nurses were (70.42±15.61), (96.84±13.15) and (62.24±11.02), respectively. Pearson correlation analysis showed that job engagement was positively correlated with structural empowerment and psychological resilience ( r=0.637, 0.670, P<0.01). The results of structural equation model showed that psychological resilience had a partial mediating effect between structural empowerment and job engagement. The mediating effect value was 0.321, accounting for 48.86% of the total effect. Conclusions:In this study, the structural empowerment, psychological resilience and job engagement of clinical nurses are above the medium level, and psychological resilience has a partial mediating effect between structural empowerment and job engagement. Nursing managers should fully empower nurses at the organizational level, take targeted measures to improve their psychological resilience and enhance their level of work engagement.

Objective: Some pharmacological treatments are ineffective in parts of patients with major depressive disorder (MDD), hence this needs prediction of effective treatment responses. The study aims to examine the relationship between dynamic functional connectivity (dFC) of the hippocampal subregion and antidepressant improvement of MDD patients and to estimate the capability of dFC to predict antidepressant efficacy. Methods: The data were from 70 MDD patients and 43 healthy controls (HC); the dFC of hippocampal subregions was estimated by sliding-window approach based on resting-state functional magnetic resonance imaging (R-fMRI). After 3 months treatment, 36 patients underwent second R-fMRI scan and were then divided into the response group and non-response group according to clinical responses. Results: The result manifested that MDD patients exhibited lower mean dFC of the left rostral hippocampus (rHipp.l) compared with HC. After 3 months therapy, the response group showed lower dFC of rHipp.l compared with the non-response group. The dFC of rHipp.l was also negatively correlated with the reduction rate of Hamilton Depression Rating Scale. Conclusion These findings highlighted the importance of rHipp in MDD from the dFC perspective. Detection and estimation of these changes might demonstrate helpful for comprehending the pathophysiological mechanism and for assessment of treatment reaction of MDD.

Objective: The connectivity alterations in the putamen were found in revealing the neural correlates of attention-deficit/hyperactivity disorder (ADHD), but whether the effective connectivity of the putamen is atypical in ADHD remains unclear. Investigating this abnormality contributes to describing the neural circuit of ADHD at the level of macrostructural organization. Methods: Data were acquired from thirty-two boys with ADHD and fifty-two matched typically developing controls (TDC) from Peking University (Peking) dataset deposited at the Neuroimaging Informatics Tools and Resources Clearinghouse (NITRC) platform. We examined the effective connectivity of the putamen using Granger causality analysis (GCA) and then determined whether these connections could differentiate ADHD from TDC. Results: Compared with TDC, the ADHD group showed decreased effective connectivity from the left ventral rostral putamen (VRP) to left calcarine (CAL), right medial part of the superior frontal gyrus, left orbital part of superior frontal gyrus and left middle occipital gyrus (MOG). Increased effective connectivity from the left inferior occipital gyrus and right lingual gyrus to left VRP was also found in ADHD. The result of the classification accuracy showed that 72.3% of participants were correctly classified using support vector machine. Moreover, GCA values from the left VRP to left CAL and left MOG were significantly correlated with hyper/impulsive scores of patients with ADHD. Conclusion The findings may help extend our understanding of the ADHD-related neural loops.
