Objective To explore the differences in heartbeat-evoked response (HER) under drug-related cues and neutral cues in individuals with heroin use disorder (HUD), and analyze the correlation between HER potentials and immediate cue-induced craving scores. Methods Fifty HUD participants were recruited from the Chang’an Compulsory Isolation Drug Rehabilitation Center in Shaanxi Province from June to September 2024. Simultaneous acquisition of 64-channel electroencephalography (EEG) and electrocardiogram signals was performed. Twenty alternating segments of drug-related and neutral cue videos were presented, and participants rated their subjective craving after each segment using visual analogue scale (VAS) scores. Scalp EEG data were source analyzed to obtain cortical EEG signals and corresponding HER. Short-time Fourier transform was used to calculate the power spectral density (PSD) of EEG within a time window from 100 ms before the R-peak to 500 ms after it, using the R-peak as the time zero point. Cluster-based permutation testing was used to analyze PSD differences between drug-related and neutral cues in the HUD individuals. Pearson correlation analysis was performed to evaluate the correlation between HER potentials and VAS scores. Results In the 350–420 ms time window, HER potentials in the left posterior parietal, temporal, and posterior cingulate cortices were significantly lower under drug-related cues compared to neutral cues (P＜0.01); in the 140–210 ms time window, HER potentials in the right prefrontal cortex were significantly higher under drug-related cues compared to neutral cues (P＜0.01). Correlation analysis showed that HER potentials in the left temporal and left posterior cingulate cortices were significantly negatively correlated with VAS scores (P＜0.05). Drug-related cues enhanced PSD of γ power (30–100 Hz) in salience network (fronto-insular), parietal and occipital regions (P＜0.05). PSD integrations of low-γ power (40–60 Hz) in parietal region (350–400 ms) and high-γ power (70–100 Hz) in left salience network (fronto-parietal) and occipital regions (300–350 ms) were positively correlated with VAS scores (P＜0.05). Conclusions Drug-related cues may modulate cortical activity related to heartbeat perception in HUD individuals, and such dynamic changes in both time and frequency domains are stably associated with subjective craving.

Objective To summarize the clinical efficacy of modified Morrow surgery in the treatment of hypertrophic obstructive cardiomyopathy. Methods A retrospective analysis was conducted on the clinical data of patients with hypertrophic obstructive cardiomyopathy treated with modified Morrow surgery at Zhongshan Hospital Affiliated to Fudan University from 2020 to 2023. Results A total of 318 patients were enrolled, including 156 males and 162 females, with an average age of (55.6±13.1) years. Preoperative echocardiography showed a mean interventricular septal thickness of (18.1±3.8) mm, peak left ventricular outflow tract pressure difference of (86.4±24.9) mm Hg. The surgery time was (162.3±51.0) min, extracorporeal circulation time was (80.9±31.0) min, and aortic occlusion time was (44.8±20.8) min. After the surgery, transesophageal echocardiography showed that the interventricular septal thickness was (11.0±1.8) mm and left ventricular outflow tract peak pressure difference was (9.4±5.1) mm Hg. The incidence rate of postoperative complete left bundle branch block was 45.3%, Ⅲ° atrioventricular block was 3.8%, and postoperative newly developed atrial fibrillation was 3.1%. The postoperative hospital stay was (6.6±4.9) days, and one perioperative death occurred, with a mortality rate of 0.3%. The follow-up time was (10.3±9.4) months, during which the transthoracic echocardiography revealed a ventricular septal thickness of (12.9±2.9) mm and a peak left ventricular outflow tract pressure difference of (13.9±10.0) mm Hg. Conclusion The modified Morrow procedure for the treatment of hypertrophic obstructive cardiomyopathy is safe and effective, with good results in the short and medium term.

ObjectiveTo explore the clinical application value of CIE 1976 L*a*b*（Lab） color space in the differential diagnosis of early esophageal cancer and non-cancerous lesions. MethodsWe selected the endoscopic images of patients with esophageal lesions confirmed by pathology who underwent white light imaging endoscopy （WLI） and narrow band imaging endoscopy （NBI）. Five regions of interest （ROI） were selected respectively from the mucosa of the lesion area and the mucosa of the surrounding normal area for labeling. The Lab color space parameters were extracted and counted， and the color difference values（ΔE*）were calculated. ResultsA total of 213 eligible patients were included for analysis in the study. In WLI and NBI modes， there were differences in mucosal color between the early esophageal cancer group and the non-cancer group （P<0.05）. Compared with WLI mode， NBI mode could significantly increase the color difference between early esophageal cancer and non-cancerous lesions （P<0.05）. The lightness component value （L* value） of the early esophageal cancer lesion area was lower than that of the non-cancerous lesion area， and this color difference was more significant in the NBI mode （P<0.05）. In WLI mode， there was no significant difference in yellow-blue component value （b* value） between the mucosa of early esophageal cancer and non-cancerous lesions. However， in the NBI mode， the b* value of the mucosa in the non-cancerous lesion area was higher than that in the early esophageal cancer lesion area （P<0.05）. On the red-green axis， the mucosa of the early esophageal cancer and non-cancerous lesions was red in WLI mode and green in NBI mode. There was no significant difference in red-green component value （a* value） between the two groups. ConclusionThere are color differences between early esophageal cancer and non-cancerous lesions under WLI and NBI. The color of early esophageal cancer is darker under WLI， and the color of non-cancerous lesions is yellower under non-magnified NBI mode. Lab color space is helpful to identify early esophageal cancer and non-cancerous lesions.

OBJECTIVE: To elucidate the clinical and genetic characteristics of familial cases with Glucose transporter type 1 deficiency syndrome (Glut1DS). METHODS: A survey of family history was conducted on children (proband) with Glut1DS who had visited Peking University First Hospital between November 2008 and April 2024 by focusing on the clinical manifestations of family members. Peripheral venous blood (2 mL) was collected from the pediatric patients and their parents. Genomic DNA was extracted and sequenced subsequently. Sanger sequencing was performed to validate the identified variant sites of the SLC2A1 gene in the probands and their family members. The pathogenicity of suspected variants was analyzed according to the 2015 American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants. The clinical features, auxiliary examinations, and mutational characteristics of family members with SLC2A1 variants were analyzed. This study has been approved by the Clinical Research Ethics Committee of Peking University First Hospital (Ethics No. 2021 Research 332). RESULTS: Among 87 cases with Glut1DS, 10 families with autosomal dominate inherited cases were identified, accounting for 11.0% of the cases. Of the 11 children, 8 were boys and 3 were girls. The onset of the disease had ranged from 3 months to 120 months (median 6 months), with 4 cases of early-onset classic type, 2 cases of late-onset classic type, and 5 cases of non-classic type. Six children had seizures, and 7 exhibited movement disorders. Seven children underwent developmental assessment, of which 3 had mild developmental delay, 2 were borderline, and 2 were normal. Nine children underwent lumbar puncture. The cerebrospinal fluid glucose levels ranged from 1.45 to 2.25 mmol/L (median 1.86 mmol/L), and the cerebrospinal fluid to blood glucose ratios ranged from 0.29 to 0.44 (median 0.35). Among the 8 fathers with SLC2A1 gene variants, 4 were asymptomatic, 2 developed paroxysmal exercise-induced movement disorders (PED) in childhood and adulthood, respectively. 1 had poor memory since childhood, 1 developed migraines during adolescence, and his sister was an asymptomatic carrier. The father with childhood-onset PED had a cerebrospinal fluid test with CSF glucose of 1.85 mmol/L. Of the 3 mothers with SLC2A1 gene mutations, 1 was an asymptomatic carrier; 2 developed PED in childhood and after the age of 20, respectively. The mother who developed PED in childhood also had psychomotor developmental delay. Genetic testing results revealed that among 10 families, 8 carried missense variants, 1 carried a nonsense variant, and 1 carried a small fragment insertion leading to a frameshift variant. Among the 11 cases, SLC2A1 gene variants in 8 children were inherited from their fathers, while in 3 cases, the variants were inherited from their mothers. The pathogenicity of the genetic variants was evaluated according to the Standards and Guidelines for the Interpretation of Sequence Variants published by the ACMG. Among the 8 variants identified in the 10 families, 4 were classified as pathogenic variants, 1 as likely pathogenic, and 3 as variants of uncertain significance (VUS). Four variant sites, including c.204_205insTCTC (p.V69fs), c.412G>C (p.G138R), c.431T>G (p.V144G), and c.875A>G (p.Y292C), were not previously reported in the literature. Among these, the latter three were categorized as VUS. CONCLUSION Familial Glut1DS account for 11.0% of the cases in China, with the majority of SLC2A1 gene variants inherited from the fathers, predominantly missense mutations, and with an autosomal dominant inheritance pattern. Probands tend to have earlier onset and more severe symptoms than their parents, who often present with mild or no symptoms.

Parental burnout is a set of negative symptoms resulting from parenting roles and chronic paren-ting stress,such as feelings of depletion associated with the parenting role and maintaining emotional distance from children.This paper analyzes a representative body of literature on parental burnout published through 2023 and pro-vides an overview of the literature around parental burnout definition and measurement,antecedent variables,and consequential variables.The results indicate that demographic variables,individual and family factors can influence parental burnout,and that the consequences of parental burnout are primarily reflected in the parents themselves and their children.The prevalence of parental burnout is influenced by sociocultural factors,but the mechanism of action is unclear and there is less research on interventions for parental burnout.Future research should pay full attention to the role and place of sociocultural factors in the study of parental burnout and actively pursue intervention research on parental burnout.

Objective:To revise the Effort-Reward Imbalance in Household and Family Work(ERI-HF)in a sample of middle school parents,and examine its adaptation.Methods:The Parenting Behavior Effort-Reward Im-balance Scale(ERI-PB)was formed by translating and linguistically adjusting ERI-HF,combining with expert eval-uation results.Parents of 1 062 seventh-grade students in a middle school were selected and surveyed twice with an interval of one and a half months on a family basis.The Perceived Partner Responsiveness Scale(PPRS),Parenting Anxiety Questionnaire(PAQ),and Satisfaction with Marital Scale(SMS)were used to test the criterion-related va-lidity.Results:There were 22 items in ERI-PB,which contained 3 factors of effort,reward,and over-commitment,the factor load of each factor was 0.39-0.84,and the cumulative variance explanation rate was 47.27％.The ab-solute values of correlations between the scores of effort,reward,over-commitment and PPRS,PAQ,SMS were 0.14-0.53(Ps＜0.01).The Cronbach α coefficients of the three factors were 0.76-0.91,the McDonaldωcoef-ficients were 0.76-0.91,and the retest reliabilities(ICC)were 0.50-0.70.Conclusion:The ERI-PB shows good validity and reliability in a group of parents of middle school students.

ObjectiveTo evaluate the effects of Wuhua herbal tea on chronic unpredictable mild stress (CUMS)-induced depression and explore its mechanism of action in combating depression.MethodsWe tested the antidepressant effects of Wuhua herbal tea in a rat model of CUMS-induced depression using fluoxetine as a positive control. The rats were divided into four groups: control group, model group, fluoxetine group, and Wuhua herbal tea group. The rats underwent body weight measurements, sucrose preference test, and open-field test. Enzyme-linked immunosorbent assay kits were used to detect the serum levels of serotonin, dopamine, adrenocorticotropic hormone (ACTH), corticosterone, norepinephrine, and interleukin-6. Intergroup comparisons and detection of brain-derived neurotrophic factor (BDNF), cAMP-response element binding protein (CREB), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3 (STAT3) mRNA expression in the hippocampus were performed using RT-PCR. Immunohistochemistry was used to identify the expression of phosphorylated JAK2 (p-JAK2) and phosphorylated STAT3 (p-STAT3) proteins in hippocampal paraffin sections of CUMS rats.ResultsCompared with the control group, the model group rats had depressive tendencies, exhibiting low vitality and interest in various behavioral indicators which were signs of despair. The Wuhua herbal tea group statistically increased the levels of serotonin and dopamine in the serum of CUMS rats to varying degrees (P = .015 and P = .002); reduced serum levels of ACTH, corticosterone, norepinephrine, and interleukin-6 (all P .05); and decreased mRNA expression of BDNF, CREB, JAK2, and STAT3 in the hippocampus (all P .05); and decreased p-STAT3 protein levels (P = .006).ConclusionWuhua herbal tea shows antidepressant potential in CUMS rats by modulating the HPA axis and inhibiting JAK2-STAT3 overactivation, alleviating neuroinflammation. It also restores BDNF-CREB pathway function, reducing depressive symptoms.

AIM:To explore whether microRNA-30a-3p(miR-30a-3p)is involved in the pathogenesis of non-alcoholic fatty liver disease(NAFLD)by regulating autophagy and promoting lipid deposition.METHODS:Eight-week-old C57BL/6 mice were randomly divided into a normal control group and a high-fat diet(HFD)group.Mice in the HFD group were fed with 60％high fat diet for 10 weeks to induce the NAFLD phenotype.Some mice were injected with adeno-virus overexpressing miR-30a-3p via the tail vein and subsequently fed with high-fat diet for 4 weeks.Glucose tolerance and insulin resistance tests were performed at the end of the treatments.In addition,the concentrations of hepatic alanine aminotransferase(ALT),aspartate aminotransferase(AST),triglyceride(TG)and total cholesterol(TC)were mea-sured.Hematoxylin-eosin staining and oil red O staining were conducted to examine morphological changes and lipid depo-sition in the liver tissue.The expression levels of microtubule-associated protein light chain 3(LC3),autophagy-related protein 5(ATG5),beclin-1 and p62 were quantified through Western blot.In addition,NAFLD models were established in AML12 hepatocytes by incubating the cells with palmitic acid and oleic acid(PO).The AML12 cells were transfected with miR-30a-3p shRNA to knock down miR-30a-3p expression.The concentration levels of TG and TC after miR-30a-3p knockdown were measured by the kits.Nile red staining was performed to examine lipid droplet aggregation and dual fluo-rescent recombinant adenovirus Ad-mCherry-GFP-LC3B was transfected into AML12 cells to observe changes in autopha-gic flow.RESULTS:HFD-fed mice exhibited significant insulin resistance and reduced glucose tolerance,significant lip-id deposition in the liver tissue,coupled with increased hepatic ALT,AST,TG and TC levels.The expression levels of au-tophagy-related proteins LC3-Ⅱ,beclin-1,and ATG5 were decreased,while that of p62 was increased(P<0.01).More-over,miR-30a-3p overexpression significantly increased blood glucose and insulin resistance in HFD-fed mice.However,it aggravated lipid droplets deposition in liver tissue and enhanced hepatic TG,TC,AST and ALT levels.Western blot re-vealed that the expression levels of LC3-Ⅱ,beclin-1 and ATG5 were further reduced,while that of p62 was significantly in-creased(P<0.01).In vitro,we observed that the TG and TC levels,as well as lipid accumulation in PO-treated AML12 cells were increased significantly.Similarly,the expression levels of LC3-Ⅱ,beclin-1 and ATG5 were decreased,whereas that of p62 increased in PO-treated AML12 cells(P<0.01).Notably,knockdown of miR-30a-3p resulted in a significant reduction in the TG content in PO-treated AML12 cells and lipid droplet aggregation was significantly suppressed.Further-more,the expression of LC3-Ⅱ,beclin-1 and ATG5 proteins was increased,while that of p62 was decreased significantly and the autophagy flow was improved(P<0.01).CONCLUSION:The miR-30a-3p exacerbates hepatic lipid deposi-tion,inducing severe hepatic steatosis and liver damage,to promote the occurrence and development of NAFLD in mice.Mechanistically,its effects involve inhibition of hepatic autophagy level.
