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］

[Objective] To evaluate the clinical application value of intrauterine perfusion with platelet-rich plasma (PRP) combined with in vitro fertilization-frozen-thawed embryo transfer (IVF-FET) in patients with chronic endometritis (CE). [Methods] A randomized controlled trial (RCT) was conducted, enrolling 60 CE patients undergoing artificial cycle frozen embryo transfer at our hospital from January 2022 to January 2024. Participants were randomly divided into three groups: Group A (routine frozen embryo transfer, n=20), Group B (routine frozen embryo transfer + one PRP intrauterine perfusion, n=20), and Group C (routine frozen embryo transfer + two PRP intrauterine perfusions, n=20). Endometrial thickness during the transformation and transplantation phases, uterine artery pulsatility index (PI), resistance index (RI), systolic peak velocity/end-diastolic velocity (S/D) ratio during transplantation, serum levels of IL-2, IL-4, IL-6, IL-10, and TNF-α during transplantation, as well as biochemical pregnancy rate, clinical pregnancy rate, live birth rate, and early miscarriage rate were compared across groups. [Results] No significant differences in endometrial thickness were observed among the three groups during the transformation phase (P>0.05). During the transplantation phase, endometrial thickness in Groups C and B was significantly higher than in Group A[9.54 (8.96-10.22) and 8.90 (8.34-9.72) vs 8.37 (7.89-8.75) mm, P<0.05], with Group C showing greater thickness than Group B (Z=3.733, P<0.05). Endometrial thickness in Groups C and B during transplantation was significantly increased compared to their respective transformation phases (Z=2.191, 2.462; P<0.05). Groups C and B exhibited lower PI, RI, and S/D values than Group A[PI:1.87 (1.77-1.97), 1.94 (1.88-2.15) vs 2.43 (2.35-2.49); RI:0.75 (0.73-0.77), 0.78 (0.75-0.81) vs 0.84 (0.83-0.86); S/D:2.61 (2.33-3.42), 3.01 (2.20-3.93) vs 3.72 (3.06-4.49); P<0.05]. Group C demonstrated lower PI and RI than Group B (P<0.05). IL-2 levels in Groups C and B were higher than in Group A[3.88 (2.71-5.01), 3.59 (2.73-4.38) vs 3.16 (2.11-3.25) ng/L, P<0.05], while IL-4, IL-6, IL-10, and TNF-α levels were significantly lower (IL-4: Z=1.428, 2.421; IL-6: Z=1.754, 2.435; IL-10: Z=1.754, 2.854; TNF-α: Z=1.961, 1.765; P<0.05). Group C had lower IL-6 levels than Group B (Z=3.976, P<0.05). Biochemical pregnancy rate, clinical pregnancy rate, and live birth rate in Group C were significantly higher than in Group A (75% vs 40%, 70% vs 35%, 60% vs 20%, P<0.05). No significant differences in early miscarriage rates were observed among the groups (χ²=3.750, P>0.05). [Conclusion] Intrauterine autologous PRP perfusion in CE patients enhances pregnancy and live birth rates, improves pregnancy outcomes post-FET, and demonstrates superior efficacy in endometrial repair and receptivity with two PRP perfusions compared to a single perfusion. This provides a safe and effective therapeutic option for optimizing outcomes in CE patients with prior implantation failure.

Objective To investigate the expression of serum microRNA(miR)-340-5p,miR-155-5p and their relationship with Th1/Th2 cytokines in patients with chronic hepatitis B.Methods A total of 128 pa-tients with chronic hepatitis B in this hospital from October 2021 to October 2023 were selected as the study group,and 96 healthy subjects from the hospital during the same period were selected as the control group.The expression levels of serum miR-340-5p and miR-155-5p were detected by fluorescence quantitative PCR(qPCR),and the expression levels of serum Th1/Th2 cytokines were detected by enzyme-linked immunosor-bent assay(ELISA).The relationship between miR-340-5p,miR-155-5p and Th1/Th2 cytokines was analyzed by Pearson method,and the influence of serum miR-340-5p and miR-155-5p on the occurrence of chronic HPV infection was analyzed by Logistic regression.Results Compared with the reference group,the serum levels of miR-340-5p,miR-155-5p,IL-4,and IL-13 in the study group decreased(P＜0.05),while the levels of IFN-γand IL-12 increased(P＜0.05).Serum miR-340-5p was negatively correlated with IFN-γ and IL-12(r=-0.315,-0.293,both P＜0.05),and positively correlated with IL-4 and IL-13(r=0.413,0.412,both P＜0.05).Serum miR-155-5p was negatively correlated with IFN-γ and IL-12(r=-0.406,-0.375,both P＜0.05),and positively correlated with IL-4 and IL-13(r=0.343,0.407,both P＜0.05).Serum miR-340-5p(OR=0.735,95％CI:Increased expression levels of 0.590-0.915)and miR-155-5p(OR=0.612,95％CI:0.416-0.900)were protective factors for the occurrence of chronic hepatitis B.IFN-γ(OR=1.652,95％CI:1.170-2.333)and IL-12(OR=1.063,95％CI:1.012-1.116)were risk factors for chronic hepatitis B(P＜0.05).Conclusion Serum miR-340-5p and miR-155-5p are usually low expressed in chronic hepatitis B patients,and they are negatively correlated with Th1 cytokine level and positively correlated with Th2 cytokine level.

Objective:To explore the clinical characteristics and genetic variants in three children with late-onset Multiple acyl-Coenzyme A dehydrogenase deficiency (MADD type Ⅲ).Methods:Clinical data of three children diagnosed with late-onset MADD at the Children′s Hospital Affiliated to Zhengzhou University between March 2020 and March 2022 were retrospectively analyzed. All children were subjected to whole exome sequencing (WES), and candidate variants were verified by Sanger sequencing. All children had received improved metabolic therapy and followed up for 1 ~ 3 years.Results:The children had included 2 males and 1 female, and aged from 2 months to 11 years and 7 months. Child 1 had intermittent vomiting, child 2 had weakness in lower limbs, while child 3 had no symptom except abnormal neonatal screening. Tandem mass spectrometry of the three children showed elevation of multiple acylcarnitines with short, medium and long chains. Children 1 and 2 showed increased glutaric acid and multiple dicarboxylic acids by urine Gas chromatography-mass spectrometry (GC-MS) analysis. All children were found to harbor compound heterozygous variants of the ETFDH gene, including a paternal c. 1211T>C (p.M404T) and a maternal c. 488-22T>G variant in child 1, a paternal c. 1717C>T (p.Q573X) and a maternal c. 250G>A (p.A84T) variant in child 2, and a paternal c. 1285+ 1G>A and maternal c. 629A>G (p.S210N) variant in child 3. As for the treatment, high-dose vitamin B2, levocarnitine and coenzyme Q 10 were given to improve the metabolism, in addition with a low fat, hypoproteinic and high carbohydrate diet. All children showed a stable condition with normal growth and development during the follow-up. Conclusion:The compound heterozygous variants of the ETFDH gene probably underlay the muscle weakness, remittent vomiting, elevated short, medium, and long chain acylcarnitine, as well as elevated glutaric acid and various dicarboxylic acids in the three children with type Ⅲ MADD.

Background Metacognition,the capacity to monitor and control one's cognitive processes,has been identified as a crucial component of effective decision-making and behavioral adaptation.Previous research has revealed cognitive deficits in patients with major depressive disorder(MDD),while findings about metacognitive capacities in patients with MDD have been inconsistent across studies,and the exact relationship between metacognitive capacities and clinical symptoms in MDD patients remains uncertain.Objective To examine the metacognitive capacities of adolescent hospitalized patients with MDD and to explore its relationship with depressive and anxiety symptoms,thus providing an unprecedented insight into the prevention of MDD.Methods A coherent 56 adolescent hospitalized patients with MDD in the Psychiatry Department at the Affiliated Hospital of Southwest Medical University from March 2022 to June 2023 and met the diagnostic criteria for depression as defined by the Diagnostic and Statistical Manual of Mental Disorders,fourth edition(DSM-IV)were enrolled as MDD group.At the same time,62 healthy individuals matched with the age and sex of the MDD group residing in Luzhou were concurrently selected as control group.The metacognitive ability of the two groups was evaluated by perceptual decision-making task and confidence rating task,and the indicators included confidence deviation,reaction time of confidence evaluation and metacognitive efficiency.Additionally,the severity of depressive and anxiety symptoms was measured with Beck Depression Inventory(BDI)and Beck Anxiety Inventory(BAI).Pearson correlation analysis was utilized to examine the relationship between metacognitive capacities and clinical symptoms.Results MDD group scored higher on BDI and BAI when compared with control group(t=-13.722,-9.674,P<0.01).In terms of decision-making performance,no statistically significant difference was noted in accuracy and response time between two groups(t=-0.655,0.975,P>0.05).In terms of metacognitive performance,MDD group reported a reduction in overall confidence,confidence in correct decisions,confidence in incorrect decisions and metacognitive efficiency compared with control group(t=3.044,2.769,2.836,3.667,P<0.01).MDD group demonstrated significantly longer confidence evaluation response time than that of control group(t=-2.561,P<0.05).Correlation analysis revealed that among the MDD patients,overall confidence,confidence in correct decisions and confidence in incorrect decisions were negatively correlated with BDI score(r=-0.310,-0.307,-0.298,P<0.05),and the overall confidence and confidence in correct decisions were negatively correlated with BAI score(r=-0.284,-0.280,P<0.05),while no statistical significance existed in the correlation between confidence in incorrect decisions and BAI score(r=-0.229,P>0.05).Furthermore,metacognitive efficiency in MDD patients exhibited negative correlation with both BDI and BAI scores(r=-0.269,-0.290,P<0.05).Conclusion Hospitalized adolescent patients with MDD have impaired metacognition,and metacognitive capacity is found to be associated with severity of depressive and anxiety symptoms.

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.
