Objective: To explore the relationship of family function with sleep and externalizing problem behaviors of preschool children, so as to provide a guidance for externalizing problem prevention and intervention among preschool children. Methods: From October 2023 to January 2024, a convenience sampling method was used to select 5 138 preschool children from kindergartens in 8 districts of Wuhan City, Hubei Province. Parents completed the survey for Family Adaptability and Cohesion Scale, children s sleep habits and Child Behavior Checklist (CBCL). Spearman correlation analysis was used to examine the correlation of family function with scores of sleep quality and externalizing problem behaviors among preschool children. A mediation model analysis and bootstrap test were conducted to further investigate the mediating role of sleep quality between family function and externalizing problem behaviors. Mplus 8.7 software was used for latent profile analysis of family function. Results: The reported rates of poor sleep quality and externalizing problem behaviors among preschool children were 11.8% ( n =607), 20.0% ( n =1 026). The relevant analysis results showed that family function was negatively correlated with sleep quality and externalizing problem behaviors ( r = -0.20, -0.23), and sleep quality was positively correlated with externalizing problem behaviors ( r =0.27) ( P <0.01). The mediation effect test showed that family function negatively predicted externalizing problem behaviors ( β =-0.079) and sleep quality ( β = -0.075), while sleep quality positively predicted externalizing problem behaviors ( β =0.215) ( P <0.01). The latent profile analysis results showed that family function could be classified into 4 categories: high family function group (23.01%), upper middle family function group (44.65%), moderate family function group (26.24%) and low family function group (6.11%). Compared to high family function, the other three categories significantly positively predicted externalizing problem behaviors, and the mediating effects of sleep quality on different categories of family function were statistically significant [upper middle family function: mediation effect value was 0.022 (95% CI =0.004-0.041) and direct effect value was 0.329 (95% CI =0.263-0.396); middle family function: mediation effect value was 0.087 (95% CI =0.063-0.115) and direct effect value was 0.491 (95% CI =0.416-0.565); low family function: mediation effect value was 0.144 (95% CI =0.107-0.185) and direct effect 0.621 (95% CI =0.503-0.740)] ( P < 0.05 ). Conclusion Family function negatively predicts the externalizing problem behaviors of preschool children, and sleep quality plays a partial mediating role.

Objective:To compare the diagnostic efficacy of the added 99Tc m-methoxyisobutylisonitrile (MIBI) SPECT/CT imaging (tomography imaging) after early or delayed planar imaging in different types of hyperparathyroidism, and to seek for the optimal timing of preoperative imaging. Methods:A total of 339 patients (148 males, 191 females, age (52±13) years) with primary or secondary hyperparathyroidism and pathological results from January 2016 to June 2024 in the Second Affiliated Hospital of Soochow University were retrospectively analyzed. The patients were divided into primary early tomography imaging group ( n=63) and delayed tomography imaging group ( n=47), secondary early tomography imaging group ( n=89) and delayed tomography imaging group ( n=140). χ2 test was used to compare the diagnostic efficacies of early and delayed tomography imaging. Results:The difference of accuracy between primary delayed (98.40%(185/188)) and early tomography imaging (94.84%(239/252)) was statistically significant ( χ2=3.90, P=0.048). There were significant differences in sensitivity (77.29%(405/524) and 85.40%(275/322)), accuracy (75.89%(425/560) and 83.99%(299/356)) and negative predictive value (14.39%(20/139) and 33.80%(24/71)) between secondary delayed and early tomography imaging ( χ2 values: 8.33, 8.61, 10.70, all P<0.01). Conclusion:The optimal timing of preoperative 99Tc m-MIBI SPECT/CT imaging for primary and secondary hyperparathyroidism is after delayed planar imaging and after early planar imaging respectively.

Objective:To analyze the advantages of human epididymis protein 4 (HE4) compared with traditional tumor markers in the diagnosis and treatment of lung cancer.Methods:From February 2021 to June 2022, 230 lung cancer patients (138 males, 92 females; age (61.1±12.3) years), 96 benign lung disease patients (62 males, 34 females; age (60.2±14.8) years; including 43 cases of lung benign placeholder and 53 cases of pulmonary infection), and 60 healthy volunteers (40 males, 20 females; age (62.8±11.4) years) from the Second Affiliated Hospital of Soochow University were prospectively collected. Serum HE4, carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), cytokeratin 19 fragment (CYFRA21-1), pro-gastrin-releasing peptide (ProGRP) and carbohydrate antigen (CA)125 were detected by electrochemical analysis. The expression of HE4 in tumor tissues of 55 patients with lung cancer was detected by immunohistochemical method. χ2 test, Mann-Whitney U test, Kruskal-Wallis rank sum test and Bonferroni correction method were used to analyze data. The diagnostic efficiencies of HE4 and other tumor markers were evaluated by ROC curve analysis and the difference of AUCs was analyzed by Delong test. Results:The positive expression rate of HE4 in adenocarcinoma tissue was significantly higher than that in non-adenocarcinoma tissue (93.1%(27/29) vs 23.1% (6/26); χ2=28.01, P<0.001). The level of serum HE4 in the lung cancer group (70.70(51.93, 109.05) pmol/L) was significantly higher than that in the pulmonary benign placeholder group (59.80(48.20, 73.50) pmol/L) and the healthy control group (55.25(44.60, 74.25) pmol/L), and that in the pulmonary infection group (97.90(76.62, 155.00) pmol/L) was higher than that in the lung cancer group ( H=46.19, all P<0.008 (Bonferroni correction method)). The levels of serum HE4 were significantly different in age, sex, smoking, disease stage and pathological types in early stage ( z values: from -5.07 to 9.83, all P<0.05). The ROC curve analysis indicated that the optimal cut-off value of serum HE4 for diagnosing lung cancer was 79.22 pmol/L, with the sensitivity and specificity of 41.30%(95/230) and 83.33%(50/60). Compared with other traditional tumor markers, serum HE4 and CA125 showed the higher diagnostic value (AUC CA125 (0.695)>AUC HE4(0.656)>AUC CEA(0.614)>AUC CYFRA21-1(0.599)>AUC ProGRP (0.501)>AUC NSE (0.470)). The combination of HE4 with other traditional tumor markers significantly improved the diagnostic efficacy (AUC=0.750; z=2.75, P=0.006). Conclusions:HE4 is highly expressed in lung adenocarcinoma by immunohistochemistry. Serum HE4 exhibits a great application value in the differential diagnosis between benign and malignant pulmonary nodules, and plays an important role in assessment of patients′ conditions.

Objective:To design and synthesize 89Zr-deferoxamine(DFO)-G4C2, a novel molecular probe targeting programmed cell death receptor 1(PD-1), and evaluate its in vivo biodistribution and microPET/CT imaging characteristics in tumor-bearing mice. Methods:DFO-G4C2 was prepared by coupling DFO with G4C2, a monoclonal antibody targeting PD-1. The affinity and binding specificity of this amalgamation were subsequently assessed through the implementation of flow cytometry and surface plasmon resonance techniques. The molecular probe 89Zr-DFO-G4C2 was achieved by labeling DFO-G4C2 with the radioisotope 89Zr, and the labeling efficiency and in vitro stability of 89Zr-DFO-G4C2 were determined. Mouse models laden with CT26 colorectal cancer cells expressing PD-1 were established, followed by in vivo biodistribution and microPET/CT imaging studies, to explore the potential clinical value of 89Zr-DFO-G4C2. Additionally, the validity of this molecular probe was verified in 4T1 breast cancer models, affirming its efficacy as an imaging tool across different tumor models. Independent-sample t test was used to analyze the data. Results:DFO-G4C2 exhibited an affinity constant KD of (0.55±0.02) μmol/L, indicating a strong binding affinity. The binding rate to mouse PD-1 protein was determined to be (61.82±8.49)%. The labeling rate of 89Zr-DFO-G4C2 reached a high level of (98.76±0.51)%. Furthermore, the labeling rates in lysate and human serum after 144 h were measured to be (93.07±2.16)% and (83.42±3.21)%, respectively. MicroPET/CT imaging of CT26 tumor-bearing mice injected with 89Zr-DFO-G4C2 showcased pronounced radioactivity uptake in the tumor tissue. At 72 h post-injection, the tumor uptake value reached (10.47±0.34) percentage activity of injection dose per gram of tissue (%ID/g). The tumor uptake observed in the blocked experimental group, wherein an excess of unlabeled antibody was administered, was significantly lower at (6.26±1.03) %ID/g in comparison to the non-blocked group ( t=6.67, P=0.003). The in vivo biodistribution results were consistent with the observed microPET/CT imaging outcomes. MicroPET/CT imaging observations in the 4T1 breast cancer bearing mouse model were analogous to those obtained from the CT26 model. Conclusion:ImmunoPET based on the 89Zr-DFO-G4C2 molecular probe can non-invasively and visually assess the PD-1 expression level of tumors in vivo, and it is expected to be a new molecular imaging technique for immunotherapy monitoring of PD-1 inhibitors.

Objective:To understand the incidence and spatial-temporal distribution characteristics of hepatitis B among residents in a county of western Liaoning province from Jan 2011 to Dec 2021.Methods:Data on hepatitis B incidence were obtained from the Disease Prevention and Control Center of the county,and its crude incidence and standardized incidence were calculated.ArcGIS software was used to analyze the global spatial autocorrelation analysis and local spatial autocorrelation analysis of hepatitis B incidence in the county.A space-time scan analysis was performed using SaTScan software to identify the case distribution and spatiotemporal clustering patterns of hepatitis B incidence.Results:From Jan 2011 to Dec 2021,there were 2 978 cumulative cases of hepatitis B in the county,with a crude incidence of 69.25 per 100 000 and a standardized incidence of 70.13 per 100 000.Among different regions,Toutai Manchu Town had the highest crude incidence of hepatitis B,followed by Gaotaizi Town and Chengguan Street.The global autocorrelation showed an aggregated distribution in 2014,2016,2019,and 2021.The local autocorrelation hotspots were clustered in the central and western parts of the county,the H-H clustering areas included Toutai Manchu Town and Jiudaoling Town from 2014 to 2016,Toudaohe Manchu Town,Yizhou Street and Chengguan Street from 2017 to 2019,and Qianyang Town and Yizhou Street from 2020 to 2021.The L-L clustering areas were mostly concentrated in the southwest of the county,including Dizangsi Manchu Township,Dadingbao Manchu Township and Liulonggou Manchu Township.A total of 4 clustering areas were obtained by temporal-spatial scanning analysis,the first-level area was Zhangjiapu Township in 2017,the second-level area included Qianyang Town and Chengguan Street from 2011 to 2015,the third-level area was Gaotaizi Town from 2013 to 2016,and the fourth-level area was Toutai Manchu Town from 2014 to 2017.Conclusions:From Jan 2011 to Dec 2021,the incidence of hepatitis B among residents in a county in western Liaoning Province is mainly concentrated in the central and northwest regions.The hepatitis B cases are clustered in the central and western areas of the county,and has a trend of gradually spreading to the northern areas over time.It is necessary to pay attention to the townships with high incidence of hepatitis B and carry out effective prevention and surveillance.

Jinlingzi San is a formula frequently used in treating pain syndrome， first recorded in the Collection of Writings on the Mechanism of Disease， Suitability of Qi， and the Safeguarding of Life as Discussed in the 'Basic Questions' written by LIU Wansu in the Jin Dynasty. Jinlingzi San is composed of 2 Chinese medicinals Toosendan Fructus and Corydalis Rhizoma with a concise composition and exact clinical efficacy， having been included in the Catalogue of Ancient Classical Formulas （Second Batch： Han Chinese Medicine）. The formula name， historic evolution， medicine origins， composition， dosage， decocting methods， and ancient and modern clinical application were sorted out and analyzed with the bibliometric method. A total of 209 pieces of information were collected from ancient books and literature. After screening， 49 pieces of effective data involving 45 ancient books were included. Results showed that the name of Jinlingzi San was first recorded in Secret Formulas of the Yang Family written by Yang Tan in the Southern Song Dynasty and developed into 3 other versions of the decoction. The Jinlingzi San included in the Collection of Writings on the Mechanism of Disease， Suitability of Qi， and the Safeguarding of Life as Discussed in the 'Basic Questions' written by LIU Wansu invariably plays a dominant role. As for the 3 other versions， although they have the same name of Jinlingzi San， their composition and indications are different from those of the original formula， which were therefore viewed as prescriptions based on Jinlingzi San and also included in the research. The medicine origins and processing of Jinlingzi San are suggested： Toosendan Fructus is the dry mature fruit of Melia toosendan of Meliaceae， and the crude is used after cleansing without putamen. Corydalis Rhizoma is the dry tuber of Corydalis yanhusuo of Papaveraceae， which is used after impurity removal， cleaning， and drying. Depending on the conversion from the measurement system in the Jin Dynasty to modern measurement， it is suggested that Toosendan Fructus and Corydalis Rhizoma （41.3 g each） are ground into fine powder， and one dose includes 12.39 g of the powder， which should be taken with an appropriate amount of wine. If wine is not suitable for the patient， the decoction can also be taken with warm water. Jinlingzi San has the effects of soothing the liver， discharging heat， and activating blood to stop pain. As recorded in ancient books， Jinlingzi San is specialized in treating heart pain caused by reversal heat， chest and abdominal pain， hypochondriac pain， jaundice， hernia， and other diseases. Modern studies have shown that modified Jinlingzi San can be used in treating diseases involving the digestive system， the integumentary system， the gynecological system， the reproductive system， and other systems and has wide clinical application in treating epigastric pain， herpes zoster， dysmenorrhea， and other diseases. This study has made clear the key information of Jinlingzi San by textual research of ancient books and literature in the hope of providing a theoretical reference for the clinical application， set prescriptions， and new drug development.

Objective    To summarize the surgical strategy of reoperative aortic root replacement after prior aortic valve replacement (AVR), and analyze the early and mid-term outcomes. Methods    From April 2013 to January 2020, 75 patients with prior AVR underwent reoperative aortic root replacement in Fuwai Hospital. There were 54 males and 21 females with a mean age of 56.4±12.7 years. An emergent operation was performed in 14 patients and an elective operation in 61 patients. The indications were aortic root aneurysm in 38 patients, aortic dissection involving aortic root in 30 patients, root false aneurysm in 2 patients, prosthesis valve endocarditis with root abscess in 2 patients, and Behçet's disease with root destruction in 3 patients. The survival and freedom from aortic events during the follow-up were evaluated with the Kaplan-Meier survival curve and the log-rank test. Results    The operative procedures included prosthesis-sparing root replacement in 45 patients, Bentall procedure in 26 patients, and Cabrol procedure in 4 patients. Operative mortality was 1.3% (1/75). A composite of adverse events occurred in 5 patients, including operative death (n=1), stroke (n=1), and acute renal injury necessitating hemodialysis (n=3). The follow-up was available for all 74 survivors, with the mean follow-up time of 0.5-92.0 (30.3±25.0) months. Four late deaths occurred during the follow-up. The survival rate at 1 year, 3 years and 6 years was 97.2%, 91.4% and 84.4%, respectively. Aortic events developed in 2 patients. The rate of freedom from aortic events at 1 year, 3 years, and 6 years was 98.7%, 95.0% and 87.7%, respectively. There was no difference in rate of survival or freedom from aortic events between the elective patients and the emergent patients. Conclusion    Reoperative aortic root replacement after prior AVR can be performed to treat the root pathologies after AVR, with acceptable early and mid-term outcomes.
