BackgroundIn recent years， the incidence of depression among adolescents has been increasing steadily， posing a serious threat to their physical and mental health and even leading to severe consequences such as self-harm and suicide. At the same time， the detection rate of subclinical depression symptoms among adolescents is even higher. Although these symptoms do not meet the clinical diagnostic criteria， they have significantly affected their quality of life， and their persistence over time may further develop into depression. Therefore， in-depth exploration of adolescent depression symptoms and the predictive factors holds significant practical significance and research value. However， up to now， no large-scale investigation and research on depression symptoms among children and adolescents has been conducted in Inner Mongolia Autonomous Region. ObjectiveTo understand the prevalence of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region， in order to provide references for formulating scientific and effective prevention strategies and intervention measures. MethodsBy using the cluster stratified random sampling method， 6 281 students from the third grade of primary school to the second grade of high school in 12 leagues and cities of Inner Mongolia Autonomous Region were selected in March 2024. A self-designed questionnaire and the Self-rating Depression Scale （SDS） were used for on-site investigation. ResultsA total of 6 058 （96.45%） children and adolescents completed the valid questionnaire survey， and 2 728 cases （45.03%） were found to have depressive symptoms. There were statistically significant differences in the detection rates of depressive symptoms among children and adolescents of different genders， ages， whether they were only children， different family types， family monthly income， parents' educational levels， and whether the mother was employed （χ²=33.769， 40.618， 48.593， 29.972， 142.648， 195.999， 168.190， 5.445， P<0.05 or 0.01）.The results of the Logistic regression analysis showed that for children and adolescents， being female， aged between 12 and 16， over 16 years old， not being an only child， living in a reconstituted family， having a monthly family income of less than 5 000 yuan， and having parents with an education level of primary school or below were predictors of depressive symptoms （OR=1.241， 1.427， 1.273， 1.177， 1.549， 1.278， 1.462， 1.417， 1.514， 1.929， 1.660， 1.528， P<0.05 or 0.01）. ConclusionThe detection rate of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Factors that may predict depressive symptoms in children and adolescents include female gender， ages between 12 and 16， ages over 16 years old， non-only children， families with a restructured structure， monthly family income of less than 5 000 yuan， and parents with an education level of primary school or below. ［Funded by Science and Technology Planning Project of the Inner Mongolia Autonomous Region （number， 2022YFSH0119）］

Compared to other refractive surgeries, the implantable collamer lens(ICL)implantation procedure has become one of the most popular surgical options in refractive surgery. ICL surgery offers advantages such as reversibility, high-definition visual outcomes, and preservation of the corneal anatomical structure. The V4c model, which features a central port, is currently the most widely used in clinical practice and eliminates the need for peripheral iridotomy during the perioperative period. Although excellent uncorrected visual acuity can be achieved postoperatively, some patients may experience visual disturbances in the early postoperative period, such as halo and glare, which may affect visual comfort particularly under low-light conditions. This article reviews visual quality metrics after ICL V4c implantation, including higher-order aberrations(HOA), modulation transfer function(MTF), and contrast sensitivity(CS), along with influencing factors, and discusses potential relative deficits in postoperative visual quality and their underlying mechanisms.

Objective:To investigate the current situation of uncivilized behavior in workplace encountered by nurses in Xianyang City, and analyze its influencing factors, so as to provide a basis for formulating corresponding intervention measures.Methods:In May 2023, convenience sampling was used to investigate the general information, current situation of uncivilized behavior in workplace and coping style of 1310 nurses in 8 secondary and tertiary general hospitals in Xianyang City by using the general information questionnaire, the Chinese version of the Nurse Incivility Scale and the Simplified Coping Style Questionnaire. Multiple linear regression analysis was used to analyze the influencing factors of uncivilized behavior encountered by nurses.Results:A total of 1285 valid questionnaires were collected, with an effective recovery rate of 98.09%. The total score of uncivilized behavior encountered by nurses was (86.41±22.49) points. Among them, the scores of five dimensions were nurses' uncivilized behavior (19.95±4.70) points, patients' uncivilized behavior (23.66±8.96) points, supervisors' uncivilized behavior (13.25±4.87) points, doctors' uncivilized behavior (14.32±5.63) points and colleagues' uncivilized behavior (15.23±4.93) points. The multiple linear regression analysis results showed that the hospital level and coping style were the significant influencing factors of uncivilized behavior in workplace encountered by nurses ( β=0.104, 0.056; P<0.05) . Conclusion:The current situation of uncivilized behavior in workplace encountered by nurses needs to be improved. Hospital managers should focus on coping styles, such as setting up simulation scene exercises, team cooperation training, training and counseling, so as to reduce the uncivilized behavior in workplace encountered by nurses.

Objective To systematically evaluate the incidence and influencing factors of axillary web syndrome(AWS)in postoperative breast cancer patients,and to provide evidence for reducing the incidence of axillary web syndrome.Methods A computer search was performed in China National Knowledge Infrastructure(CNKI),VIP,Wanfang,SinoMed,PubMed,Medline,Scopus,The Cochrane Library,Web of Science,Embase,searched for articles on AWS influencing factors of breast cancer published from the establishment of the database to January 6th,2025.The articles were screened according to the inclusion and exclusion criteria.Revman5.4 and Stata17.0 were used for systematic review.Results Fifteen studies involving 3979 breast cancer patients and 1 156 patients with AWS were included.The results of the Meta-analysis showed that there was significant statistical heterogeneity among the included studies(I2=97.0%,P<0.0001).Using the random effects model,the incidence of AWS was 32.2%[95%CI(0.24,0.40),P<0.0001].The influencing factors for AWS after breast cancer surgery are age,body mass index(BMI),total mastectomy,lymph node metastasis,and neoadjuvant chemotherapy.NAC),axillary lymph node dissection(ALND),and the number of harvested axillary lymph nodes.Conclusion The incidence of AWS after breast cancer surgery was high.Clinicians should give early nursing to the influencing factors,reduce the incidence of AWS and improve patients'quality of life after surgery.

Objective To explore the characteristics and diagnostic value of coronary computed tomography angiography(CCTA)and dynamic load computed tomography myocardial perfusion imaging(CT-MPI)in patients with obstructive coronary artery disease(CAD)complicated by type 2 diabetes mellitus(T2DM).Methods A total of 187 patients with obstructive CAD were selected and divided into T2DM group(n=70)and non-T2DM group(n=117).All patients underwent CCTA and dynamic load CT-MPI exami-nations.The characteristics of CCTA and dynamic load CT-MPI were observed,and their diagnostic values were analyzed.Results The degree of stenosis,total plaque volume,lipid plaque volume,calcified plaque volume,myocardial perfusion abnormality,and myocardial blood flow(MBF)were independent influencing factors for obstructive CAD complicated by T2DM(P＜0.05).These parameters demonstrated significant diagnostic efficiency on patients with obstructive CAD complicated by T2DM(P＜0.05).Conclusion Obstruc-tive CAD patients complicated by T2DM exhibit characteristics such as high vascular stenosis,severely reduced blood perfusion,and a high prevalence of high-risk plaques.Both CCTA and dynamic load CT-MPI have substantial diagnostic value on this population.

Objective:To systematically search for literature on the relationship between interoception, anxiety, and depression in patients with chronic diseases, and explore the role of emotion regulation strategies and alexithymia in this relationship.Methods:Using Arksey and O'?Malley's scoping review methodology as the theoretical framework, a systematic search was conducted on CNKI, Wanfang Data, VIP, China Biology Medicine disc, PubMed, Web of Science, Embase, and CINAHL. The search period was from January 1, 2013, to August 31, 2024. The included literature was summarized and analyzed.Results:A total of 14 articles were included, investigating the relationship between three interoception dimensions of 11 chronic diseases and anxiety and depression. The specific impact of different dimensions of interoception on anxiety and depression varied according to the type of disease. The interaction between emotion regulation strategies and alexithymia was a potential factor influencing the relationship between interoception and anxiety and depression in patients with chronic diseases.Conclusions:The relationship between interoception and anxiety and depression is influenced by the type of disease and individual differences. Healthcare professionals should strengthen the multidimensional assessment and intervention of the interoception of patients with chronic diseases, combined with personalized psychological support and cognitive intervention strategies to actively prevent and reduce the risk of anxiety and depression in patients.

Objective To investigate the characteristics of CT myocardial perfusion imaging in chronic total occlusion(CTO)patients and explore its role in assessing coronary collateral circulation and viable myocardium.Methods A cohort of 50 CTO patients were enrolled and underwent both CT myocardial perfusion imaging and coronary angiography.Age,body mass index,gender,chronic comorbidities,coronary artery dominance and CT myocardial perfusion imaging parameters were compared across different patient groups:normal myocardial perfusion,matched myocardial perfusion(reduced resting and stress perfusion),mismatched myocardial perfusion(normal resting but reduced stress perfusion),and Rentrop grade-stratified subgroups(grade 0,1,2 and 3).Results No significant differences in age and body mass index were observed among normal myocardial perfusion group,matched myocardial perfusion group(P>0.05).However,gender distribution,chronic comorbidities and coronary artery dominance differed significantly between groups(P<0.05).Myocardial perfusion reduction on CT was predominantly observed in males,particularly those complicated by chronic diseases and right coronary artery dominance.There was no statistical significance in age and body mass index among patients stratified by Rentrop grade(0,1,2 and 3)(P>0.05),while significant differences emerged in gender distribution,chronic comorbidities and coronary artery dominance(P<0.05).The opening of collateral circulation predominantly occurred in males,particularly those with chronic comorbidities and right coronary artery dominance.Significant differences were found in myocardial blood flow(MBF),myocardial blood volume(MBV),mean transit time(MTT)and time to peak(TTP)among normal myocardial perfusion group,matched myocardial perfusion group and mismatched myocardial perfusion group(P<0.05).The differences in MBF,MBV,TTP and MTT among patients stratified by Rentrop grade(0,1,2,and 3)were significant(P<0.05).Conclusion Significant differences exist in CT myocardial perfusion imaging parameters among CTO patients with varying degrees of coronary collateral circulation and myocardial viability.These parameters may serve as important clinical evaluation indicators.

Objective To observe the value of MRI radiomics combined with ResNet101 deep learning for differentiating lumbar spine brucella spondylitis(BS)and spinal metastases(SM).Methods Seventy-one cases of lumbar spine BS and the same amount of lumbar spine SM patients were retrospectively enrolled in training set,while 33 cases of lumbar spine BS and the same amount of lumbar spine SM patients were enrolled in test set.Clinical features were screened with univariate and multivariate logistic analysis,and a clinical model(Mclinic)was constructed.ROI of lesions were drawn on lumbar sagittal T 2WI,then radiomics features were extracted to construct a radiomics model(Mradiomics).ResNet101 deep learning was integrated with radiomics,then deep learning radiomics features were extracted to construct deep learning radiomics model(MDL+R).Finally a combined model(Mcombined)was constructed through combining clinical features and deep learning radiomics features.The efficacy of the above models for differentiating BS and SM were analyzed.Results Significant differences of patients' age and proportion of fever and accessory involvement were found between BS and SM patients in training and test sets(all P＜0.05),and univariate and multivariate logistic analysis showed the latter two were clinical features(both P＜0.001).The area under the curve(AUC)of Mclinic for differentiating lumbar spine BS and SM was 0.794 and 0.773 in training set and test set,of Mradiomics was 0.895 and 0.791,of MDL+R was 0.926 and 0.882,while of Mcombined was 0.967 and 0.906,respectively.AUC of Mcombined was the highest in training set(all P＜0.05),while in test set,AUC of Mcombined was significantly higher than that of Mclinic and Mradiomics(both P＜0.05).Conclusion MRI radiomics combined with ResNet101 deep learning was helpful for differentiating lumbar spine BS and SM.Combining with clinical data could improve its diagnostic efficacy.

Objective:To explore the clinicopathological and molecular genetic characteristics of anaplastic lymphoma kinase (ALK)-rearranged renal cell carcinoma (RCC), including a rare case with the TPM1-ALK gene subtype.Methods:Three cases of ALK-rearranged RCC diagnosed in the Department of Pathology, the First Affiliated Hospital of Zhengzhou University, Zhengzhou, China from January 2020 to December 2024 were collected. Their clinical pathological and next-generation sequencing (NGS) data were analyzed. Relevant literature was also reviewed, and follow-ups were carried out.Results:Among the three patients, there were 1 female (case 1) and 2 males (cases 2 and 3), with the ages of 29,41 and 44 years, respectively. All of them were presented with space-occupying renal lesions. Case 1 (KIAA1217-ALK RCC) showed mixed cystic and solid components under the microscope, with tubular, papillary, and cribriform arrangements. The tumor cells had clear boundaries, and were cubic or low columnar, arranged in a single layer, pseudostratified or in sheets. The cytoplasm was abundant and eosinophilic, and part of the cytoplasm was vacuolated, as if there was accumulation of mucoid substances. The tumor cell nuclei were oval with prominent nucleoli. A large amount of mucus and inflammatory cell infiltration were noted in the stroma. Case 2 (TPM1-ALK RCC) showed a papillary growth pattern, with small, slender papillae accompanied by branches. The cells were arranged in a single layer, and the cytoplasm was either eosinophilic or clear. Foamy cells were aggregated in the stroma, accompanied by psammoma body-like calcifications. Case 3 (EML4-ALK RCC) was characterized by papillary and tubulocystic structures. The cytoplasm was abundant and eosinophilic. The tumor cell nuclei were large, with prominent nucleoli. There was conspicuous infiltration of lymphocytes and neutrophils in the fibromuscular stroma. The tumor cells all expressed epithelial markers, PAX8, GATA3, P504s and FH. ALK (5A4) staining showed diffuse strong expression in the cytoplasm, while TFE-3 was positive (nuclear stain) only in case 1 and case 3. The fluorescence in situ hybridization showed that ALK gene rearrangement was present in all three cases, while TFE-3 gene rearrangement/mutation was not detectable in case 1 and case 3. NGS showed the KIAA1217::ALK fusion (the fusion site in the exon 11 of KIAA1217 and exon 18 of ALK) in case 1, the TPM1::ALK fusion (the exon 8 of TPM1 and exon 20 of ALK) in case 2, and the EML4::ALK fusion (the exon 2 region of EML4 and the exon 20 region of ALK) in case 3.Conclusions:ALK-rearranged RCC has unique molecular characteristics. Its histological morphology is easily confused with that of papillary RCC and TFE3-rearranged RCC. Both immunohistochemistry and gene rearrangement tests should be used to confirm the diagnosis.

Objective:To analyze the clinical and genetic features of a child with Primary ciliary dyskinesia (PCD) due to compound heterozygous variants of the CCDC39 gene and a 22q11.21 deletion, and to explore the potential role of the two types of variants in the formation of complex phenotypes. Methods:A child presented at the Shanxi Children′s Hospital in March 2025. due to multiple congenital anomalies was selected as the study subject. Peripheral blood samples were taken from the child and her parents and subjected to whole-exome sequencing (WES). Candidate variants were verified by Sanger sequencing. Effect of splicing variant was predicted using SpliceAI, and pathogenicity was assessed based on the ACMG guidelines. Copy number variation (CNV) analysis was also performed. This study has been approved by the Medical Ethics Committee of the Hospital (Ethics No.: IRB-WZ-2025-019).Results:The patient has exhibited multiple features including severe pneumonia, bronchiectasis, localized pulmonary emphysema, scoliosis, tetralogy of Fallot, and atrial septal defect. Genetic testing revealed that she has harbored compound heterozygous variants of the CCDC39 gene, namely c. 1167+ 1G>A and c. 1009A>T, which were inherited from her father and mother, respectively, with the latter being a novel likely pathogenic variant. In addition, a heterozygous deletion of approximately 708 kb at 22q11.21 was detected. Conclusion:The coexistence of CCDC39 gene variants and a 22q11.21 deletion may underlay the development of complex clinical phenotypes in this child.
