Gastric cancer is a common tumor in China, and lymph node metastasis (LNM) is an independent prognostic factor for it. Accurately determining the risk of LNM in gastric cancer can help to formulate the treatment plan and estimate its staging and prognosis preoperatively. Existing means for evaluating LNM in gastric cancer have shortcomings such as low accuracy and high subjectivity. In recent years, artificial intelligence (AI) has begun to be used in medical research and clinical fields, which is of great significance in the era of precise individualized medicine. Combined with multimodal data including clinical, imaging, pathomics and molecular information, AI can improve the accuracy of LNM diagnosis and assist clinical decision-making, which has made significant progress recently. The aim of this review is to provide an overview of the history and status of AI for LNM prediction in gastric cancer, and to discuss the challenges and development directions.

Objective:To explore the spatial correlation between gray matter volume (GMV) changes and neurotransmitter receptors/transporters in patients with first-episode schizophrenia (FES) .Methods:Fifty-four FES patients(FES group) and fifty-nine healthy controls (HC group) were selected from June 2014 to May 2020 in the Psychiatry Department of Renmin Hospital of Wuhan University. Structural magnetic resonance imaging (sMRI) was conducted on all subjects. Differences of GMV were compared across 400 cortical regions and 32 subcortical regions. Based on the positron emission tomography(PET) data from Neuromaps, which provides the density of 19 different neurotransmitter receptors and transporters, Spearman correlation analysis was performed to evaluate the spatial correlation between GMV changes and neurotransmitter systems.Results:Compared to the HC group, FES group exhibited significant GMV reductions in widespread cortical (90/400) and subcortical (6/32) regions (all FDR-corrected P<0.05). The effect size of GMV reduction (Cohen’s d) showed significant positive correlations with the density of 5-hydroxytryptamine 1a(5HT1a) ( r=0.400, Pspin=0.002), γ-aminobutyric acid type A receptor(GABA A)( r=0.307, Pspin=0.002), and metabotropic glutamate receptor 5(mGluR5) ( r=0.275, Pspin=0.020) receptors (all FDR-corrected P<0.05). Conclusion:GMV reductions in a wide range of brain regions existed in patients with FES. There are significant correlations between 5HT1a, GABA A and mGluR5 receptors and gray matter reduction in patients with FES. The disorder of these neurotransmitter receptors may be the potential neurobiological mechanism of gray matter structural abnormalities in the early stage of schizophrenia.

Objective:To investigate the clinical application value of a novel filter's retraction hook capture technique of pull-assisted method for the endovascular retrieval of conical inferior vena cava (IVC) filters whose hook attached to the wall.Methods:From January 2020 to December 2024, patients with conical filters whose hook attached to the wall admitted at Beijing Jishuitan Hospital were enrolled consecutively.Results:A total of 46 patients underwent filter retrieval using filter's retraction hook capture technique of pull-assisted method. Among these patients, 39 cases (84.8%) were successful in filter retrieval, with the penetration distance of cranial anchor vertex of 3.3(2.5, 4.4) mm, and 13 (33.3%) filters were deformed. The other 7 cases were unsuccessful, with a penetration distance of cranial anchor vertex of 5.0 (4.3, 5.0) mm, and 6 (85.7%) filters were deformed. There was a statistically significant difference between the two groups ( P<0.05). One case (2.2%) had IVC injury, one case (2.2%) experienced filter fracture, and no symptomatic pulmonary embolism occurred. Logistic regression analysis showed that filter deformation was an independent dangerous factor for filter's retraction. Conclusions:Filter's retraction hook capture technique of pull-assisted method is effective in removing conical filters whose hook attached to the wall, with no symptomatic PE occurring. This method can be considered as a new adjuvant technique for filter retrieval.

Objective:To summarize the clinical characteristics of congenital chylothorax (CC) in neonates, and to analyze the effects of conservative treatment and the prognosis.Methods:A case control study was conducted.Clinical data of neonates with CC treated in the Department of Neonatal Surgical Intensive Care Unit, Guangzhou Women and Children′s Medical Center Guangzhou Medical University, from January 2015 to April 2023 were collected.The patients were divided into a survival group and a death group according to the outcome.SPSS 26.0 software was used for statistical analysis, and binary Logistic regression was used for the analysis of risk factors for death.Results:A total of 55 patients were included in this study, including 35 males and 20 females.The gestational age at birth and birth weight were 37.1 (34.7, 38.7) weeks and 3 250 (2 640, 3 540) g, respectively.Among the patients included, 30 cases had bilateral pleural effusion, 25 cases had unilateral pleural effusion, and 22 cases had hydrops fetalis; 50 cases were prenatally diagnosed with pleural effusion, with the mean gestational age at diagnosis being 31.0(26.0, 34.6) weeks.Additionally, 21 cases had polyhydramnios, and 18 cases had mediastinal displacement.Ten cases received intrauterine treatment and 17 cases were treated with octreotide.The maximum daily amount of pleural effusion was 31.7(12.0, 62.5) mL/kg, and pleural effusion resolved within 14 (6, 22) days.The length of hospital stay was 23 (12, 36) days.Forty-four cases survived, while 11 cases died.The differences in polyhydramnios, gestational age, bilateral pleural effusion, hydrops fetalis and Apgar score were significant between the survival and death groups (all P<0.05).Binary Logistic regression analysis revealed that bilateral pleural effusion and a low 5-minute Apgar score were independent risk factors for early death in neonates with CC (all P<0.05).A total of 38 children were followed up at the age of 2.30 (1.24, 3.46) years.There was 1 case of recurrence, and none of the patients experienced recurrent respiratory infections. Conclusions:CC is most common in full-term infants and has a predominantly bilateral effusion, its long-term prognosis with conservative treatment is promising.However, neonates with CC who present with bilateral pleural effusion or low 5-minute Apgar scores have an increased risk of early mortality.

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 investigate the clinical characteristics of omphalocele, and to assess the risk factors associated with adverse outcomes.Methods:A retrospective cohort study was conducted. Clinical data of 224 patients diagnosed with omphalocele, who were hospitalized at Children′s Hospital, Zhejiang University School of Medicine from January 2013 to December 2022, were collected. Based on their discharge outcomes, the patients were classified into 2 groups: favorable outcomes and unfavorable outcomes. Chi-square test or continuity correction χ2 test or Fisher exact probability method, and Mann-Whitney U test were used for intergroup comparisons. Logistic regression analysis was performed to identify risk factors associated with adverse outcomes in omphalocele. Results:Among the 224 patients with omphalocele, 126 were male. A total of 208 patients (92.9%) had favorable outcomes, while 16 patients (7.1%) had unfavorable outcomes. In the unfavorable outcomes group, 14 patients had giant omphaloceles, while 100 patients had giant omphaloceles in the favorable outcomes group. The rates of herniation of more than two intra-abdominal organs in the hernial sac, congenital heart defects, patent ductus arteriosus, pulmonary hypertension, sepsis and infection of the hernial sac, were all higher in the unfavorable outcomes group compared to the favorable outcomes group (all P<0.05). Patients with unfavorable outcomes had longer mechanical ventilation time, duration of oxygen use, duration of parenteral nutrition, hospital stays, and higher rates of parenteral nutrition-associated cholestasis compared to those with favorable outcomes (all P<0.01). Multivariate Logistic regression analysis indicated that pulmonary hypertension ( OR=9.39, 95% CI 1.20-73.32), sepsis ( OR=8.59, 95% CI 1.32-55.86), and congenital heart defects ( OR=6.55, 95% CI 1.11-38.73) were all independent risk factors for adverse outcomes in omphalocele (all P<0.05). Conclusions:Infants with omphalocele are prone to complications such as cardiovascular malformations, infections, and pulmonary hypertension. Adverse outcomes in omphalocele are associated with pulmonary hypertension, sepsis, and congenital heart defects.

Objective:This study investigated the expression level of phosphatidylserine-specific phospholipase A1(PLA1A)in colorectal can-cer(CRC)and analyzed its correlations with clinicopathological features,prognosis,and immune infiltration.Methods:The expression level of PLA1A in CRC was screened,and the influence of this expression level on patient prognosis was analyzed using bioinformatics methods.A cohort of 192 patients diagnosed with CRC at Shanxi Province Cancer Hospital from January to December 2020 were selected.The PLA1A ex-pression level in those with CRC was determined using immunohistochemistry(IHC)and real-time quantitative reverse transcription PCR(RT-qPCR).The relationship between PLA1A level and the clinicopathological features of the patients with CRC was analyzed using the chi-square test.The expression levels of immune cell markers CD4 and CD8 as well as immunosuppressive checkpoints PD-1,TIM-3,and CTLA-4 in CRC were detected via IHC,and their correlations with PLA1A level were analyzed using the chi-square test.Results:The results of bioinformatics analysis showed that the expression level of PLA1A in CRC tissue was higher than paracancerous tissue,which correlated with overall surviv-al(OS)(P<0.05).The IHC and RT-qPCR results showed that PLA1A expression level was significantly upregulated in CRC tissiue(P<0.05).High PLA1A level was closely associated with the TNM stage,degree of differentiation,and lymph node metastasis(P<0.05).The IHC results demonstrated that PLA1A positively correlated with the infiltrating CD8+T cell level(P<0.05).In addition,the elevated PLA1A levels upregu-lated the expressions of immunosuppressive checkpoints PD-1,TIM-3,and CTLA-4(P<0.05).Conclusions:PLA1A is highly expressed in CRC,which is closely related to immune infiltrating cells and immunosuppressive checkpoints,suggesting that PLA1A plays an important role in immune infiltration in CRC,a finding that provides guidance in the treatment of CRC.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
