Objective: To explore the association between executive function and emotional and behavioral problems in first-grade elementary school students, so as to provide a reference for promoting children s mental health. Methods: From March to May 2024, 423 first-grade elementary school students from 6 primary schools aged 6-7 were selected by using stratified cluster random sampling in Shanxi, Shanghai, Shandong, Guangxi, Xinjiang, and Jiangxi. Data were collected by using the Executive Function Assessment Scale and the Strengths and Difficulties Questionnaire. An independent samples t-test was used to analyze differences in executive function of different genders and differences in emotional and behavioral problems among first-grade school students with varying executive function levels; a linear regression model was employed to analyze the association between children s executive function and emotional and behavioral problems. Results: A total of 42 first-grade elementary school students (9.9%) were identified as having executive function deficits. Students in the executive function deficit group scored higher on internalizing behavior (7.50±0.52), externalizing behavior (11.26±0.52), and total difficulties (18.52± 0.93 ) were significantly higher than those of children without deficits (4.37±0.14, 6.69±0.17, 10.64±0.27) ( t =5.79, 8.50, 9.23, all P <0.05). Results of linear regression analysis showed that, after controlling for relevant covariates such as gender, age, family economic status, being an only child, and body mass index, the factor scores, dimensional scores, and total scores of executive function were all positively correlated with scores for externalizing problems, internalizing problems, and total difficulties ( β =0.07-0.32, all P <0.05). Conclusions Children s executive function is closely associated with emotional and behavioral problems, and those with poorer executive function exhibit more pronounced emotional and behavioral problems. Improving children s executive function may help promote their mental health.

Objective:To explore the relationship between coronary artery measurements combined with C-reactive protein(CRP), erythrocyte sedimentation rate(ESR) and coronary artery lesionsin(CAL) with incomplete Kawasaki disease (IKD) in children.Methods:Sixty-eight cases of pediatric IKD admitted to Huaibei Maternal and Child Health Care Hospital from January 2020 to April 2024 were selected as the IKD group, and 34 healthy children undergoing physical examination during the same period were selected as the control group according to the principle of 2∶1 pairing. Echocardiographic Z values including left coronary artery (LCA)-Z, right coronary artery (RCA)-Z, left anterior descending branch (LAD)-Z, left circumflex branch (LCX)-Z and CRP, ESR were compared between the two groups. General information of children with or without CAL were compared. The multivariate Logistic regression was used to screen the risk factors of IKD combined with CAL, and receiver operating characteristic (ROC) curve was used to analyze the predictive value of each index to IKD combined with CAL.Results:The LCA-Z, RCA-Z, LAD-Z, LCX-Z and the levels of CRP, ESR in the IKD group were higher than those in the control group: 3.26 ± 0.97 vs. 1.35 ± 0.28, 3.46 ± 0.92 vs. 1.01 ± 0.29, 3.18 ± 0.69 vs. 1.18 ± 0.34, 2.97 ± 0.68 vs.1.27 ± 0.34, (39.97 ± 9.03) mg/L vs. (4.21 ± 1.05) mg/L, (59.67 ± 16.34) mm/1 h vs. (12.85 ± 2.43) mm/1 h, there were statistical differences ( P<0.05). The duration of fever, intravenous immunoglobulin (IVIG) treatment response, IVIG start time, creatine kinase (CK), creatine kinase-MB(CK-MB), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) between the children with IKD and CAL, IKD without CAL: (10.02 ± 2.45) d vs. (7.68 ± 1.43) d, 65.22%(15/23) vs. 88.89%(40/45), 60.87%(14/23) vs. 86.67%(39/45), (236.78 ± 59.74) U/L vs. (192.67 ± 35.41) U/L, (45.19 ± 9.85) U/L vs. (33.18 ± 9.87) U/L, (1.78 ± 0.32) μg/L vs. (0.92 ± 0.20) μg/L, there were statistical differences ( P<0.05). Logistic regression analysis showed that the duration of fever, IVIG treatment response, IVIG initiation time, CK, CK-MB, NT-proBNP, echocardiographic Z value, CRP and ESR levels were independent risk factors for IKD combined with CAL ( P<0.05). ROC curve analysis results showed that the area under the curve of IKD combined with CAL predicted by LCA-Z, RCA-Z, LADE-Z, LCX-Z, CRP and ESR was the largest, which was 0.917 (95% CI 0.824 - 0.970), which was higher than that diagnosed by each index alone ( P<0.05). Conclusions:There is a certain relationship between the echocardiographic Z values, CRP and ESR in children with IKD and CAL, which can be used to assist in the evaluation of IKD complicated with CAL.

Objective To analyze the short-term prognosis of two treatment methods for severe Cerebral venous sinus thrombosis (Cerebral Venous Sinus Thrombosis,CVST) and to explore the best treatment for severe CVST patients. Methods From January 2013 to January 2019,28 patients with severe cvst were diagnosed by neurosurgery in the first people’s hospital of Kunming. They were divided into two groups:simple internal anticoagulant therapy,anticoagulation and combined endovascular treatment. Results Anticoagulant combined with intravascular treatment group has a better short-term prognosis than that of medical anticoagulant group alone,the difference is statistically significant(P<0.05). Conclusions For patients with severe CVST,interventional therapy can be tried to improve the short-term prognosis.

Objective To compare the effects of ticagrelor and clopidogrel on platelet aggregation rate, myocardial perfusion and prognosis in patients with acute myocardial infarction. Methods One hundred and sixty-nine patients with acute ST segment elevation myocardial infarction (STEMI) and emergency percutaneous coronary intervention (PCI) were recruited and randomly divided into ticagrelor group (85 cases) and clopidogrel group (84 cases). The TIMI blood flow before and after PCI was recorded, and the ST segment fall rate of 1 h ECG after PCI was calculated. The platelet aggregation rate was measured. After 12 months' follow-up, the incidence of major adverse cardiac events (MACE) was recorded. The Logistic regression analysis was used to discover the factors of MACE. Results One hundred and sixty-nine patients with acute STEMI were recruited including 85 cases treated with ticagrelor and 84 cases in clopidogrel group. The ECG ST segment fall rate after PCI in ticagrelor group was significantly higher than that in clopidogrel group: (61.3 ± 30.7)％ vs. (47.8 ± 26.6)％, P<0.05. The platelet aggregation rate 2 h, 24 h and 7 d after PCI in ticagrelor group was significantly lower than that in clopidogrel group (P<0.05). MACE occurred in 19 cases (22.4％) in ticagrelor group and in 21 cases (25.0％) in clopidogrel group, and there was no significant difference (P > 0.05). Multiple Logistic regression analysis revealed that age and ECG ST segment fall rate were independent risk factors for MACE (P<0.05). Conclusions Compared with clopidogrel, ticagrelor can effectively reduce platelet aggregation rate and accelerate ST segment fall in STEMI patients, but their long-term prognosis is similar.

Objective To explore the change and clinical significance of the serum carcinoembryonic antigen (CEA)and carbohydrate antigen 724(CA724)in patients with rectal cancer before and after neoadjuvant ra-diotherapy and chemotherapy.Methods The serum levels of CEA and CA724 of 30 patients with rectal carci-noma were detected by electrochemiluminescence method and were compared with those in 30 healthy people. Results The serum levels of CEA and CA724 in rectal carcinoma patients before neoadjuvant radiotherapy and chemotherapy were significantly higher than those in the healthy people,the difference was statistically significant(P<0.05).The serum levels in complete remission and partial remission patients after eight-week neoadjuvant radiotherapy and chemotherapy were significantly lower than those before treatment,the differ-ence was statistically significant(P<0.05),and the reduction levels were obviously higher than those in the stable group,the difference was statistically significant(P< 0.05).The CEA and CA724 levels in the stable treatment patients were also lower than those of before neoadjuvant radiotherapy and chemotherapy,the difference was statistically significant(P<0.05).The serum levels in the progression group were higher than those of before treatment(P<0.05).The serum levels of CEA and CA724 before neoadjuvant radiotherapy and chemotherapy existed a positive correlation(r=0.862,P=0.000).Conclusion The serum levels of CEA and CA724 in rectal cancer are highly expressed,suggesting that both of them are closely related to the occur-rence and development of rectal carcinoma,the measurement of the serum level changes of CEA and CA724 in patients with rectal cancer before and after treatment contributes to estimate the efficacy of neoadjuvant radio-therapy and chemotherapy and tumor progression.

Objective To investigate the predictive value of serum adiponectin level on morbidity of acute myocardial infarction, and to evaluate its impact on prognosis in patients with acute myocardial infarction after percutaneous coronary intervention (PCI). Methods We prospectively recruited patients with acute ST segment elevation myocardial infarction (STEMI) who had underwent primary PCI. Their serum adiponectin levels were measured. The TIMI blood flow classification of culprit vessel was recorded after PCI. Echocardiography was performed in 24 h after PCI to evaluate left ventricular ejection fraction (LVEF). Major adverse cardiac events (MACE) were recorded including cardiac death, recurrent nonfatal myocardial infarction, target vessel reascularization, and readmission for heart failure after 18 months′ followed-up. Results 108 consecutive patients with STEMI and 38 control patients without coronary artery stenosis were recruited. The serum adiponectin level in STEMI group was significantly lower than that in control: (1 413.9 ± 218.8) ng/L vs.(1 756.3 ± 205.5) ng/L (P<0.01). STEMI patients with LVEF < 50% had lower serum adiponectin level compared with LVEF ≥50%: (1 334.1 ± 226.3) ng/L vs. (1 453.0 ± 213.8) ng/L , P<0.01. The serum adiponectin level in the TIMI 0-2 group after PCI was significantly lower than that in the TIMI 3 group:(1 350.7 ± 214.9) ng/L vs. (1 430.6 ± 218.5) ng/L, P < 0.01. Multiple logistic regression analysis revealed that lower serum adiponectin level was an independent predictor of STEMI ( OR=0.992, 95% CI 0.987-0.996, P<0.01). MACE occurred in 22 patients (20.4% ). Cox regression analysis revealed that lower serum adiponectin level remained an independent predictor of MACE ( OR=0.996, 95% CI 0.993-0.999, P < 0.01). Conclusions Lower serum adiponectin level is significantly associated with morbidity of STEMI and adverse prognosis in patients with acute myocardial infarction.

Objective To investigate the expression of circulating tumor cells (CTC) in peripheral blood of patients with different stages of colorectal cancer (CRC), and to evaluate its significance in early diagnosis of colorectal cancer metastasis. Methods Sixty patients with CRC (42 inⅡ-Ⅲstage and 18 in IV stage ) and 30 patients with benign rectal disease were recruited from January 2014 to December 2015. The CTC in peripheral blood was purified with Immunomagnetic Separation Technologie, and detected by immunofluorescence in situ hybridization (imFISH). The serum levels of CEA were detected by electrochemiluminescence method meanwhile. The correlation between CTC and CEA was analyzed. Results CTC positive rates in CRC patients were significantly higher than those in benign rectal disease controls. CTC positive rates inⅣstage were significantly higher than those inⅡ-Ⅲ stage. The expression of CTC was significantly correlated with CEA (r = 0.6652, P < 0.01). Conclusions The expression of CTC in CRC patients is significantly higher than that in benign rectal disease control group. It is closely related to clinical stages. Detection of peripheral blood CTC has important clinical significance in the early diagnosis of CRC metastasis.
