Objective: To explore the mediating effect of rumination between life events and learning value doubt among junior high school students, so as to provide reference for the psychological health education of junior high school students. Methods: From March to July 2023, a total of 930 junior high school students from Guangdong, Jiangsu and Hebei were selected by a combination of convenient sampling methods. Participants completed the Scales of Value of Learning (SVL), Ruminative Response scale (RRS) and Adolescent Self rating Life Events Checklist (ASLEC). The t test and ANOVA were used for inter group comparisons and Pearson correlation analysis was used for correlation analysis and bootstrap method was used for mediating effect test. Results: The life events of junior middle school students were positively correlated with learning value doubt ( r =0.18), rumination ( r = 0.65 ) and its three dimensions (brooding, reflective pondering, and symptom focused rumination) ( r =0.60, 0.59, 0.66). Learning value doubt was positively correlated with rumination ( r =0.15) and its three dimensions ( r =0.07, 0.13, 0.19) ( P <0.05).The symptom focused rumination (effect size=0.09, 95% CI =0.06-0.11) and brooding (effect size=-0.07, 95% CI =-0.09--0.04) dimensions partially mediated the relationship between life events and learning value doubt. In the two influential pathways, symptom focused rumination exerts a stronger impact, and the difference was statistically significant (effect size=0.15, 95% CI =0.11- 0.20 , excluding 0) ( P <0.05). Conclusions Life events experienced by junior high school students can positively predict learning value doubt through symptom focused rumination, and negatively predict learning value doubt through brooding. Active attention should be paid to the mental health status of junior high school students, intervene promptly when they experience life events, reduce symptom based rumination, and improve their learning enthusiasm.

Objective To investigate the diagnostic value of the T2WI gray scale ratio for Hashimoto's thyroiditis(HT).Methods The T2WI-iterative decomposition of water and fat with echo asymmetry and least square estimation(IDEAL)quantitation sequence water images of 22 HT cases were analyzed retrospectively.The gray scale ratio of the thyroid,sternocleidomastoid muscle,trachea cavity,and subcutaneous fat at the same layer were measured on the picture archiving and communication systems(PACS).The gray scale ratios of thyroid/sternocleidomastoid muscle(T/M),thyroid/trachea cavity(T/Tr),and thyroid/lipid(T/L)were calculated.The intraclass correlation coefficient(ICC)was used to evaluate the consistency among the measurements,and the optimal threshold for distinguishing HT from non-HT was determined via the receiver operating characteristic(ROC)curve.The Spearman correlation analysis was used to analyze the correlation between T/M,T/Tr,T/L ratios,and titers of thyroid peroxidase antibody(TPO-Ab)and thyroglobulin antibody(Tg-Ab),respectively.Results On the T2WI-IDEAL quantitation sequence water images,the(x)±s of T/M,T/Tr,T/L ratios for HT and non-HT were 2.17±0.47 and 1.62±0.21(t=14.90,P<0.001),9.40±3.24 and 4.87±2.93(t=11.42,P<0.001),1.66±0.32 and 1.21±0.31(t=7.51,P<0.001),respectively.The area under the curve(AUC)of T/M,T/Tr,and T/L ratios for diagnosing HT were 0.89,0.86,and 0.85,respectively;the optimal thresholds were 1.90,3.50,and 1.36,and the sensitivity and specificity were 72.7%and 100%,100%and 40.5%,95.5%and 29.7%,respectively.The T/M ratio had a moderate correlation with TPO-Ab(r=0.513,P<0.05),and T/Tr,T/L ratios had a mild correlation with TPO-Ab,respectively.Conclusion The T/M ratio in the T2WI gray scale ratio can quantitatively and objectively distinguish HT from non-HT to some extent and is correlated with TPO-Ab.It has extremely high specificity and holds promise as a non-invasive imaging method for the diagnosis of incidental HT.

A 70-year-old man had radical surgery for colon cancer one year before the symptoms of memory loss and decreasing cognitive function.Subsequent magnetic resonance imaging revealed a brain mass,which was surgically resected and confirmed to be metastatic intestinal adenocarcinoma.Immunohistochemistry of the primary tumor and brain metastasis showed mismatch repair deficiency.The patient received adjuvant chemotherapy after surgery.However,the brain metastasis relapsed one month after the last chemotherapy.Genetic testing on the resected colon tumor samples confirmed microsatellite instability-high with a high tumor mutation burden by 77.7 muts/Mb.The patient was subsequently treated with programmed death-1(PD-1)monoclonal antibody pembrolizumab(keytruda).The brain metastatic lesions were completely shrunk,and a complete clinical response was achieved.

Objective:To explore the relationship between parental mediation and adolescents'tendency of online game addiction,and the effect of self-control in it.Methods:Totally 553 senior high school students were tested with the Chinese version of Parental Mediation of Online Activities Questionnaire,Internet Gaming Disorder Scale-Short-form(IGDS9-SF)and Dual-mode of Self-control Scale for Adolescents(DMSC-S).Parental active me-diation,restrictive mediation,Internet game addictive tendency,adolescent self-control impulsive system,control system were evaluated respectively.SPSS macro program PROCESS was used to test the mediating role.Results:The scores of restrictive mediation of parents were negatively associated with the scores of adolescents'tendency of online game addiction(β=-0.14,P＜0.001).Self-control scores played an independent mediating role between parental active mediation scores and online game addiction tendency scores(indirect effect=-0.09,95％CI=-0.09--0.01)and a partial mediating role between parental restrictive mediation scores and online game addiction tendency scores(indirect effect=-0.04,95％CI=0.00-0.07).Conclusion:Parental active and restrictive medi-ation are related to adolescents'tendency of online game addiction.Self-control plays a partial mediating role.

Objective:To explore the changes of bone turnover markers and geometric parameters of hip bone in overweight postmenopausal women with metabolic syndrome(MS), as well as the influence of MS components. To analyze the association of these factors with the risk of fracture.Methods:A total of 505 overweight postmenopausal female patients who underwent health check-up in Lianhu Community Service Center, Danyang City, Jiangsu Province from January to December 2017 were selected. According to the MS diagnostic criteria of the International Diabetes Federation(2009), the patients were divided into MS group( n=331)and non-MS group( n=174). Blood samples were collected to determine the level of procollagen type 1 N-terminal propeptide(P1NP)and carboxy-terminal cross-linked telopeptide of type 1 collagen(CTX). Bone mineral density and hip bone geometry parameters were tested with dual-energy X-ray absorptiometry and hip structural analysis software. Results:The incidence of osteoporotic fracture and hip fracture in MS group was significantly higher than that in non-MS group(21.1% vs 13.8%, 4.8% vs 1. 1%, P<0.05). However, the bone mineral density of lumbar vertebra 1-4, femoral neck, and total hip in MS group was significantly higher than that in non-MS group, which remained after adjusting for age( P<0.05), but the difference disappeared after further adjustment for body mass index( P>0.05). The P1NP, CTX, femur strength index(FSI), section modulus(SM), and cross-sectional area(CSA)of MS group were significantly lower than those of non-MS group, the buckling ration(BR)was significantly higher than that in non-MS group, and the differences were still statistically significant after adjusting for age and body mass index( P<0.05). There was no significant difference in bone mineral density of lumbar vertebra 1-4, femoral neck, total hip, P1NP, and CTX between fracture group and non-fracture group in patients with MS. But FSI, SM, cross-sectional moment of inertia(CSMI), and CSA were significantly lower, BR was significantly higher( P<0.05) and femur strength decreased in patients with fracture. Regression analysis showed that high BR was an independent risk factor for fracture risk, while high FSI, SM, CSMI, and CSA were protective factors. Multivariate linear regression analysis showed that wasit circumference, diastolic blood pressure, and fasting plasma glucose were the main MS components affecting bone mineral density, bone turnover indexes, and hip bone geometry parameters. Conclusions:Overweight postmenopausal MS patients had decreased bone turnover rate, femoral strength, and relatively poor bone quality. Hip bone geometry parameters can be used as one of the methods to assess fracture risk in MS patients. Waist circumference, diastolic blood pressure, and fasting blood glucose are the important MS components affecting bone mass and bone quality.

BACKGROUND: Sarcopenia is an age-related progressive skeletal muscle disorder involving the loss of muscle mass or strength and physiological function. Efficient and precise AI algorithms may play a significant role in the diagnosis of sarcopenia. In this study, we aimed to develop a machine learning model for sarcopenia diagnosis using clinical characteristics and laboratory indicators of aging cohorts. METHODS: We developed models of sarcopenia using the baseline data from the West China Health and Aging Trend (WCHAT) study. For external validation, we used the Xiamen Aging Trend (XMAT) cohort. We compared the support vector machine (SVM), random forest (RF), eXtreme Gradient Boosting (XGB), and Wide and Deep (W&D) models. The area under the receiver operating curve (AUC) and accuracy (ACC) were used to evaluate the diagnostic efficiency of the models. RESULTS: The WCHAT cohort, which included a total of 4057 participants for the training and testing datasets, and the XMAT cohort, which consisted of 553 participants for the external validation dataset, were enrolled in this study. Among the four models, W&D had the best performance (AUC = 0.916 ± 0.006, ACC = 0.882 ± 0.006), followed by SVM (AUC =0.907 ± 0.004, ACC = 0.877 ± 0.006), XGB (AUC = 0.877 ± 0.005, ACC = 0.868 ± 0.005), and RF (AUC = 0.843 ± 0.031, ACC = 0.836 ± 0.024) in the training dataset. Meanwhile, in the testing dataset, the diagnostic efficiency of the models from large to small was W&D (AUC = 0.881, ACC = 0.862), XGB (AUC = 0.858, ACC = 0.861), RF (AUC = 0.843, ACC = 0.836), and SVM (AUC = 0.829, ACC = 0.857). In the external validation dataset, the performance of W&D (AUC = 0.970, ACC = 0.911) was the best among the four models, followed by RF (AUC = 0.830, ACC = 0.769), SVM (AUC = 0.766, ACC = 0.738), and XGB (AUC = 0.722, ACC = 0.749). CONCLUSIONS: The W&D model not only had excellent diagnostic performance for sarcopenia but also showed good economic efficiency and timeliness. It could be widely used in primary health care institutions or developing areas with an aging population. TRIAL REGISTRATION Chictr.org, ChiCTR 1800018895.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).

Self-control brings important effects on the process and maintenance of health behavior change in individuals, but its mechanism is unclear.Healthy behavior change could be divided into goal-oriented behavior initiation stage, combating habit rejection stage, and habit acquisition and maintenance stage.Established theories of health behavior change mainly focus on the conflict between the goal-directed behavior initiation phase and habitual behavior.It is also indicated that disgust is the key mechanism to restrain the implementation of goal-oriented behavior, but ignore the mechanisms in the action implementation and new behavior acquisition phases.In fact, goal-directed and habitual behaviors work together to ensure that individuals adapt efficiently to their environment.However, when goal-oriented behavior becomes habitual, old habit and new goal-oriented behavior begin to compete, causing conflicts and aversion.The core phase of self-control functioning is just in the confrontation with habit rejection phase.On the one hand, self-control directly assists individual goal-directed behavior habituation through conflict sense adaptation.On the other hand, intensive management and stimulus control indirectly assist goal-directed behavior habituation through the relief of conflict sense.Further exploration of the theory and clinical practice of self-control affecting healthy behavior change is needed in the future.

Objective:To evaluate the quality of life (QoL) of Chinese chronic pancreatitis (CP) patients based on the Chinese version of the pancreatitis quality of life Instrument (PANQOLI) and explore its impact factors.Methods:404 patients with CP admitted to the Department of Gastroenterology of the First Affiliated Hospital of Naval Medical University between September 2021 and January 2022 were enrolled. The Chinese version of PANQOLI was used for questionnaire survey on QoL of CP patients. Univariate analysis and multiple linear regression analysis were used to explore the impact factors for QoL of CP patients.Results:The total score of QoL of 404 Chinese CP patients was 28-94(72.47±13.61), which declined by 29.64% compared to the highest total score (103) in the Chinese version of PANQOLI. Score of physical function, role function, emotional function, and self-worth domain was 25.63±4.84, 13.86±2.78, 16.98±6.21 and 16.00±4.65, respectively. Compared to the highest scores (30, 25, 24 and 24), the scores of aforementioned four domains declined by 14.57%, 44.56%, 29.25% and 33.33%, respectively. Univariate analysis showed that sex, age, employment status, smoking, alcohol consumption, and frequency of pancreatitis recurrence were significantly associated with QoL of CP patients. Multiple linear regression analysis indicated that older age (coefficient=-0.127), unemployment status (coefficient=-0.106), smoking (coefficient=-0.176), and high frequency of pancreatitis recurrence (coefficient=-0.123) were independent factors for QoL of CP patients (all P value <0.05). Conclusions:The Chinese version of PANQOLI could be effectively applied to Chinese CP patients. Older age, unemployment, smoking, and pancreatitis attacks were risk factors for QoL of CP patients, indicating that the formulation of personalized intervention measures may help to improve QoL of CP patients.

Objective:To study the changes of early (i.e., within post injury day (PID) 14) coagulation function in patients with severe burns.Methods:A retrospective case series study was conducted. From December 2018 to December 2019, 50 severe burn patients who met the inclusion criteria were admitted to Guangzhou Red Cross Hospital of Jinan University. According to the severity of burns, the patients were divided into severe burn group (17 cases, including 12 males and 5 females) and extremely severe burn group (33 cases, including 26 males and 7 females). The platelet count (PLT), and conventional coagulation indexe and thromboelastogram index levels of patients were collected at admission, post injury hour (PIH) 48 and 72, and on PID 7 and 14. The conventional coagulation indexes included prothrombin time (PT), thrombin time (TT), activated partial prothrombin time (APTT), and fibrinogen (FIB) and D-dimer levels. The thromboelastogram indexes included coagulation angle (i.e., α angle), coagulation composite index (CI), MA value, R value, and K value (reflecting maximum amplitude, coagulation reaction time, and blood agglutination time, respectively). Data were statistically analyzed with independent sample t-test, Wilcoxon rank sum test, and chi-square test. Verification of the mixed effect model was performed on each index data of patients in the two groups, while the repeated measures analysis of variance was performed on PLT. Pearson correlation analysis or Spearman correlation analysis were performed to analyze the correlation between the thromboelastogram index data (except CI) and the PLT and conventional coagulation index data, respectively. Results:At admission, PIH 48 and 72, and on PID 7 and 14, PLT of patients in severe burn group were (203±91), (148±70), (123±63), (203±62), (402±140)×10 9/L, respectively, PLT of patients in extremely severe burn group were (235±116), (145±71), (109±52), (235±106), (455±138)×10 9/L, respectively. In overall comparison, only the difference of the main effect of time factor was statistically significant ( F=92.55, P<0.05). In severe burn group, statistically significant differences were only identified in comparison of patients' PLT between PID 7 and the adjacent two time points (at PIH 72 and on PID 14, with both P values <0.05). The differences in PLT of patients between all the adjacent time points in extremely severe burn group were statistically significant ( P<0.05). In the overall comparison of PT, TT, and FIB level of patients in the two groups at each time point, only the difference of main effect of time factor was statistically significant (with F values of 6.04, 8.45, and 32.90, respectively, all P values <0.05), and APTT and FIB level of patients in extremely severe burn group within PID 14 were higher than those in severe burn group. There were statistically significant differences in MA value, α angle, K value, and CI of patients in the two groups at each time point (with F values of 18.82, 11.38, 9.11, and 9.42, respectively, all P values <0.05). MA value was moderately correlated with PLT ( r=0.69, P<0.05), weakly correlated with TT and FIB level (with r values of -0.29 and 0.30 respectively, P<0.05), and very weakly correlated with D-dimer level ( r=-0.15, P<0.05); α angle was moderately correlated with PLT ( r=0.58, P<0.05), and weakly correlated with FIB level and TT (with r values of 0.26 and -0.29, respectively, P<0.05); R value was weakly correlated with APTT and FIB level (with r values of 0.24 and 0.31, respectively, P<0.05), and very weakly correlated with PT and TT (with r values of 0.16 and 0.14, respectively, P<0.05); K value was moderately correlated with PLT ( r=-0.59, P<0.05), and weakly correlated with FIB and TT (with r values of -0.29 and 0.32, respectively, P<0.05), and very weakly correlated with D-dimer level ( r=-0.15, P<0.05). Conclusions:Severe burn patients are already characterized with coagulation function changes in early stage, including insufficiency of coagulation function, enhanced platelet aggregation ability and enhanced FIB function. There is a certain correlation between conventional coagulation indexes and thromboelastogram indexes, but they cannot replace each other.
