BackgroundPatients with depressive disorder often exhibit impaired decision-making functions. However， the relationship between decision-making abilities and depressive and anxiety symptoms in these patients remains unclear. ObjectiveTo explore the characteristics of decision-making behavior in patients with depressive disorder， and to analyze its relationship with clinical symptoms. MethodsA total of 48 patients diagnosed with depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） were recruited from the Department of Psychosomatic Medicine of the Affiliated Hospital of Southwest Medical University from October 2020 to May 2023. Concurrently， 52 healthy individuals matched for age and gender were recruited from Luzhou as the control group. Beck Depression Inventory （BDI） and Beck Anxiety Inventory （BAI） were used for assessment， and decision-making behavior was evaluated using Probabilistic Reversal Learning （PRL） task. Indicators assessed included the number of trials to criterion， perseverative errors， win-stay rate and lose-shift rate. Spearman correlation analysis was used to assess the correlation between BDI and BAI scores and PRL task indicators. ResultsThe depression group showed a significantly higher lose-shift rate compared with the control group （t=3.684， P<0.01）. There were no statistically significant differences between two groups in trials to criterion， perseverative errors and win-stay rate （t=0.329， 0.132， 0.609， P>0.05）. In depression group， BDI and BAI scores were positively correlated with the win-stay rate（r=0.450， 0.398， P<0.01）. ConclusionPatients with depressive disorder are more likely to change their decision-making strategies following negative outcomes. Furthermore， the severity of depressive and anxiety symptoms is associated with a greater propensity to maintain existing decisions after receiving positive feedback. ［Funded by 2019 Joint Project of Luzhou Science and Technology Bureau-Southwest Medical University （number， 2019LZXNYDJ39］

Inducing the degradation of KRAS represents a novel strategy to combat cancers with KRAS mutation. In this study, we identify ubiquitin-specific protease 2 (USP2) as a novel deubiquitinating enzyme of KRAS in multiple myeloma (MM). Specifically, we demonstrate that gambogic acid (GA) forms a covalent bond with the cysteine 284 residue of USP2 through an allosteric pocket, inhibiting its deubiquitinating activity. Inactivation or knockdown of USP2 leads to the degradation of KRAS, resulting in the suppression of MM cell proliferation in vitro and in vivo. Conversely, overexpressing USP2 stabilizes KRAS and partially abrogates GA-induced apoptosis in MM cells. Furthermore, elevated USP2 levels may be associated with poorer prognoses in MM patients. These findings highlight the potential of the USP2/KRAS axis as a therapeutic target in MM, suggesting that strategically inducing KRAS degradation via USP2 inhibition could be a promising approach for treating cancers with KRAS mutations.

Objective: Self-determination theory (SDT) deems that people have three causality orientations: autonomy orientation, control orientation, and impersonal orientation. Previous studies suggested that lower autonomy orientation or higher control and impersonal orientations may be associated with more addictive behaviors. Our study aimed to investigate if these associations exist in Internet gaming disorder (IGD), and if sensation seeking, anxiety, and depression could influence the associations between causality orientations and IGD symptoms. Methods: A total of 1,400 college students completed the Internet Gaming Disorder Scale, General Causality Orientation Scale, Brief Sensation Seeking Scale, Generalized Anxiety Disorder Scale, and Patient Health Questionnaire. Correlation, multiple linear regressions, structural equation model (SEM) analyses, and moderation analyses were conducted to explore the associations. Results: The control and impersonal orientations were positively associated with IGD symptoms, while the autonomy orientation was negatively associated with them. Moreover, SEM analyses showed that the autonomy-IGD relationship was totally mediated by anxiety and depression, the impersonal-IGD relationship was partially mediated by anxiety, and the control-IGD relationship was partially mediated by depression. Finally, the effects of causality orientations on IGD were moderated by sensation seeking. Conclusion Overall, autonomy orientation is linked to fewer gaming problems, whereas control and impersonal orientations are associated with more gaming problems. Moreover, the relationships between causality orientations and IGD symptoms are mediated by anxiety and depression and moderated by sensation seeking. Our findings inform theory on the motivations of gaming behaviors and may shed light on the prevention and intervention of IGD from the perspective of SDT.

Background:Autoimmune gastritis(AIG)is a CD4+T cell-mediated immune disease.In recent years,with increased awareness and understanding of the condition,reports of AIG cases in China have been gradually increasing.Aims:To analyze and summarize the clinical characteristics of AIG for better disease recognition and diagnosis.Methods:Data on AIG patients diagnosed at the First Affiliated Hospital of Zhejiang Chinese Medical University from August 2018 to December 2023 were collected and analyzed for their clinical,laboratory,endoscopic,and pathological features.Results:A total of 161 AIG patients were included,with the mean age of 56.81 years old,63 were males and 98 females.Most of the patients exhibited no characteristic clinical symptoms.The laboratory measurements were as follows:gastrin-17,44.68 pmol/L;pepsinogen(PG)Ⅰ,38.61 μg/L;PG Ⅱ,10.41 μg/L;PGⅠ/Ⅱ ratio,32.1;vitamin B12,344.45 pmol/L;and hemoglobin,125.15 g/L.The positivity rates of thyroglobulin antibody and thyroid peroxidase antibody were 46.0%and 30.0%,respectively.The main comorbid autoimmune diseases were Hashimoto's thyroiditis(8.1%)and rheumatoid arthritis(5.0%).One hundred and seven cases exhibited the"reverse atrophy"phenomenon,while 54 cases showed pan-gastric atrophy,predominantly in the fundus and body.Fifteen cases were diagnosed as gastric neuroendocrine tumors(NET)or gastric carcinoma.Pathological analysis of 90 gastric mucosal specimens showed 24 cases of lymphocyte and plasma cell infiltration without significant atrophy,42 cases of glandular atrophy and lymphocyte infiltration,and 24 cases of enterochromaffin cell hyperplasia and the formation of endocrine micro-nests.Conclusions:AIG is more common in middle-aged and elderly individuals,with a slightly higher prevalence in females and a frequent association with anemia.It should be suspected in patients with low PGⅠ level and hypergastrinemia.Due to the increased risk of gastric adenocarcinoma and NETs,regular endoscopic monitoring is recommended.
