Objective:To construct evaluation indicators for the effectiveness of curriculum ideology and politics education in medical colleges and universities based on the Center for the Study of Evaluation (CSE) model.Methods:Based on the CSE-based theoretical framework of "needs evaluation, program evaluation, formative evaluation, and summative evaluation", semi-structured interviews were conducted to select indicators. The Delphi method was used to conduct two rounds of questionnaire-based consultation with 29 experts to establish a set of indicators for evaluating the effects of curriculum ideology and politics teaching of medical colleges and universities. The priority diagram was used to calculate and determine the weight of each index.Results:The authority coefficient of the 29 experts included in this study was 0.85. The Kendall's coefficients of concordance for the two rounds of expert consultation were 0.361 and 0.577 ( P<0.05), respectively. Finally, an evaluation system for the effectiveness of curriculum ideology and politics teaching was formed, including 4 first-level indicators, 9 second-level indicators, and 18 evaluation observation points. The 4 first-level indicators were "implementation objectives", "implementation plans", "implementation process", and "implementation effects". Conclusions:The CSE model is suitable as a theoretical framework for constructing the evaluation system of curriculum ideology and politics teaching in medical schools, which employs scientific indicator construction methods, follows the basic principles of course evaluation, and conforms to the current concept of ideological and political construction of medical curricula, showing certain feasibility and guiding significance.

Purpose To investigate the expression status of GNL3 in gastric cancer,and to explore the role of GNL3 in tumor proliferation,invasion and migration.Methods The ex-pression of GNL3 mRNA in gastric cancer tissues was analyzed by searching database.The expression of GNL3 protein in 51 gastric cancer tissues and 51 adjacent non-tumor tissues was de-tected by immunohistochemistry(IHC)SP method.The correla-tion between GNL3 protein expression and gastric cancer clinical pathological features was analyzed by x2 test.The expression of GNL3 in gastric cancer cells was silenced by transfection of sh-RNA,and the silencing efficiency was verified by Western blot.The effect of silencing GNL3 on the proliferation of gastric cancer cells was examined by CCK-8,colony formation and EdU stai-ning.In addition,wound-healing assay and Transwell assay were performed to detect the effect of GNL3 silencing on cell invasion and migration.Results SangerBox and UALCAN database re-trieval showed that the expression of GNL3 mRNA was signifi-cantly increased in gastric cancer tissues(P＜0.01).IHC stai-ning showed that the positive expression rate of GNL3 protein in gastric cancer tissues was 96.1％,and the high expression rate was 78.4％,which was significantly higher than that in adjacent non-tumor tissues(74.5％,51.0％,P＜0.01).Moreover,the high expression of GNL3 was significantly correlated with lymph node metastasis in gastric cancer patients(x2=4.933,P=0.026).CCK-8,colony formation and EdU staining showed that GNL3 silencing inhibited the proliferation of gastric cancer cell SGC-7901.The wound-healing and Transwell assay showed that GNL3 silencing inhibited the migration and invasion of gastric cancer cell.Conclusion The GNL3 protein is highly expressed in gastric cancer tissues,and closely related to the proliferation,migration and invasion of gastric cancer cells.

Objective:To explore the chain mediating effect of loneliness and fear of missing out between social anxiety and problematic social network usage in college students.Methods:From March to May 2023, the questionnaire survey was conducted on 957 college students using the interaction anxiousness scale, loneliness scale, fear of missing out scale and problematic social network usage scale, and the descriptive statistical, correlation analysis and mediating effect analysis were performed by the SPSS 22.0 software.Results:The scores of social anxiety, loneliness, fear of missing out and problematic social network usage were (47.09±10.00), (44.62±9.20), (12.95±4.75), and (22.63±6.94), respectively. The results of correlation analysis showed that social anxiety was significantly positively correlated with loneliness, fear of missing out and problematic social network usage ( r=0.50, 0.50, 0.51, all P<0.05). Loneliness was significantly positively correlated with fear of missing out and problematic social network usage( r=0.46, 0.45, both P<0.05).There was a significant positive correlation between fear of missing out and problematic social network usage( r=0.54, P<0.05). The mediating effect analysis showed that social anxiety had a significant direct effect on problematic social network usage (effect value=0.23, 95% CI=0.18~0.29), accounting for 48.94%(0.23/0.47) of the total effect. The separate mediating effect of loneliness (effect value=0.09, 95% CI=0.05~0.12) and fear of missing out(effect value=0.11, 95% CI=0.08~0.14) were significant, and accounted for 37.50%(0.09/0.24) and 45.83%(0.11/0.24) of the total indirect effect respectively. The chain mediating effect value of loneliness and fear of missing out was significant (effect value=0.04, 95% CI=0.03~0.06), accounting for 16.67%(0.04/0.24) of the total indirect effect. Conclusion:Social anxiety can directly affect problematic social network usage of college students and indirectly affect problematic social network usage through loneliness and fear of missing out.

Objective:To explore the relationship between social exclusion, rumination, executive function and mobile phone addiction among college students.Methods:From November to December 2023, a total of 516 college students were investigated by social exclusion questionnaire for undergraduate, ruminative responses scale, the Geurten-questionnaire of executive functioning in Chinese college students and mobile phone addiction tendency scale. SPSS 26.0 statistical software was used for common method bias test, descriptive statistics, correlation analysis, and PROCESS 3.5 macro program was used to test the mediation effect.Results:Social exclusion (31.21±12.69), rumination (42.85±12.38), executive function (71.46±9.41), and college students' mobile phone addiction tendency (43.53±11.74) were all significantly and positively correlated with each other ( r=0.299-0.500, all P<0.01). The direct effect of social exclusion on mobile phone addiction was significant (effect size=0.138, 95% CI=0.048-0.228), accounting for 37.91%(0.138/0.364) of the total effect. Rumination had a mediating effect between social exclusion and mobile phone addiction (effect size=0.053, 95% CI=0.001-0.112), accounting for 14.56%(0.053/0.364) of the total effect. Executive function mediates the relationship between social exclusion and mobile phone addiction (effect size=0.137, 95% CI=0.091-0.188), accounting for 37.64%(0.137/0.364) of the total effect.Rumination and executive function has a chain mediating effect between social exclusion and mobile phone addiction (effect size=0.036, 95% CI=0.016-0.061), accounting for 9.89%(0.036/0.364) of the total effect. Conclusion:Social exclusion can directly affect mobile phone addiction in college students and can also influence mobile phone addiction in college students through the independent mediating effects of rumination and executive function, as well as the chain mediating effect of rumination and executive function.

Purpose: Whether a dilated intrahepatic bile duct (IHBD) has any effect on the prognosis of choledochal cyst (CC) remains controversial. We aimed to summarize the clinical characteristics and prognosis of CC with IHBD dilatation. Methods: One hundred ninety-two children diagnosed with CC were identified, including 127 without IHBD dilatation (group A) and 65 with IHBD dilatation (group B). A retrospective analysis was performed to explore the clinical characteristics and prognosis of CC with IHBD dilatation based on clinical indices, symptoms, and complications. Results: Compared with group A, incidences of jaundice and fever were higher in group B (P = 0.010 and P = 0.033). Preoperative total bilirubin, direct bilirubin, and indirect bilirubin were increased in group B compared to group A (P = 0.005, P < 0.001, and P = 0.014), as were preoperative ALT, AST, γ-GT, and total bile acid (P = 0.006, P = 0.025, P < 0.001, and P = 0.024). The risk of liver fibrosis or cirrhosis was significantly increased for group B compared with group A (P = 0.012) and also occurred earlier in group B (P = 0.006). In the dilated IHBDs, 95.4% (62 of 65) recovered to normal, and more than half of dilated IHBDs (37 of 65) recovered to normal in 1 week. Conclusion Most IHBDs can recover to normal postoperatively in a short time, and proactive treatment is recommended for CC patients with IHBD dilatation for significant abnormal liver functions.

Objective:To explore the mediating effect of experiential avoidance and emotional eating between intolerable uncertainty and life satisfaction of college students.Methods:From October to December 2021, a total of 890 college students in the Beijing-Tianjin-Hebei region were tested by the intolerable uncertainty scale (simplified version), the acceptance action scale second edition, the Dutch eating behavior questionnaire and the life satisfaction scale. All data processing and analysis were preformed by SPSS 22.0 software, and the mediating effect was tested by Pearson correlation analysis and Bootstrap analysis.Results:The intolerable uncertainty score was (26.43±7.64), the experiential avoidance score was (22.63±9.67), the emotional eating score was (26.43 ±11.83), and the life satisfaction score was (16.74±6.03). Intolerable uncertainty was significantly and negatively correlated with life satisfaction( r=-0.76, P<0.01), and was significantly and positively correlated with experience avoidance and emotional eating( r=0.66, 0.78, both P<0.01). Experience avoidance was significantly and positively correlated with emotional eating( r=0.70, P<0.01), and was significantly and negatively correlated with life satisfaction( r=-0.62, P<0.01). Emotional eating was significantly and negatively correlated with life satisfaction( r=-0.68, P<0.01). Intolerable uncertainty affects life satisfaction through four paths.The direct effect value of intolerable uncertainty on life satisfaction was -0.53, accounting for 70.23% of the total effect. The separate mediating effect value of experience avoidance was -0.11, accounting for 50.00% of the total indirect effect.The separate mediating effect value of emotional eating was -0.08, accounting for 36.36% of the total indirect effect, and the chain mediating effect value of experience avoidance and emotional eating was -0.03, accounting for 13.64% of the total indirect effect. Conclusion:Intolerable uncertainty can directly affect life satisfaction of college students and indirectly through experiencing avoidance and emotional eating.

Abstract In recent years, the overall incidence of scoliosis in children and adolescents in China is on the rise, and it has become the third largest "killer" affecting the health of children and adolescents in China after obesity and myopia. The dysfunction caused by spinal deformity has no obvious pathological manifestations or clinical symptoms in children and adolescents (except for severe scoliosis). It is easy to be ignored in the early stage, but if it is not intervened in time, this will cause serious damage to the long term prognosis and quality of life of the patients. Therefore, through early scoliosis screening, we can effectively monitor the spinal health status of children and adolescents in China, ensure timely diagnosis of the disease, timely intervention (brace and other conservative treatment), and play the role of early prevention. Avoid further deterioration of scoliosis and surgical intervention. This article will focus on the research progress of screening and conservative treatment of scoliosis.

In recent years, many scholars have explored the clinical application value of a number of peripheral hematology indexes in tumor patients. The significant correlation of neutrophil to lymphocyte ratio and platelet to lymphocyte ratio with the prognosis in various tumors has also been confirmed. At present, more peripheral blood indexes have been gradually applied to the evaluation of the prognosis in patients with malignant tumors. Small cell lung cancer (SCLC) is a type of highly malignant tumor and most patients are in advanced stage at the time of diagnosis. The evaluation value of tumor stage for survival is extremely limited. Therefore, this review intends to explain the relationship between various peripheral hematology indexes and the prognosis of SCLC patients, so as to provide some academic evidence for the clinical assessment of the survival of SCLC patients and formulation of appropriate treatment strategy, which may contribute to the improvement of the prognosis.

Objective:To study the association between preoperative hemoglobin amount and incidence of lower limb deep vein thrombosis (DVT) in patients with lower limb fracture.Methods:A retrospective study was performed of the 2, 482 patients with lower limb fracture who had been treated at Department of Orthopaedics Trauma, Honghui Hospital Affiliated to Xi'an Jiaotong University from July 2014 to August 2019. They were 1, 174 males and 1, 308 females with an age of (60.6±19.3) years. Recorded were the patients' age, gender, injury time, hemoglobin amount, D-dimer measurement, combined medical conditions, time and results of ultrasound vein examination on both lower extremities. According to the ultrasound results, the patients were divided into a thrombosis group and a thrombosis-free group. The 2 groups were compared in hemoglobin amount. Logistic regression was used to analyze the relationship between preoperative hemoglobin amount and incidence of lower limb DVT. The patients were divided into 5 groups according to the quintile of hemoglobin amount; the incidences of thrombosis were compared between the 5 groups.Results:The total incidence of DVT in this cohort was 29.53%(733/2, 482). The hemoglobin amount in the thrombosis group was (116.57±19.24) g/L, significantly lower than that in the thrombosis-free group (124.76±19.79) g/L ( P<0.05). The preoperative hemoglobin amount was a risk factor for incidence of DVT after a lower limb fracture ( OR=0.985, 95% CI: 0.980 to 0.990, P<0.001). As the quintile level of hemoglobin increased, the incidence of DVT showed a downward trend. In comparison of the group with the highest DVT incidence (40.58%) and the group with the lowest DVT incidence (17.27%), the risk increased by 2.386 times (95% CI: 1.718 to 3.315). Conclusions:The preoperative hemoglobin amount can affect the DVT incidence after a lower limb fracture, and a low hemoglobin amount may more likely lead to lower limb DVT.
