Objective: To investigate the current status of benefit finding among young and middle-aged patients with type 2 diabetes mellitus (T2DM) and analyze its influencing factors, so as to provide a reference for improving the level of benefit finding in this population. Methods: From November 2022 to May 2023, young and middle-aged patients with T2DM aged 18-59 years hospitalized in the endocrinology departments of 2 tertiary hospitals in Hengyang City, Hunan Province were selected as survey subjects by a convenience sampling method. Basic demographic information was collected using a general questionnaire survey. Benefit finding, resourcefulness, and stigma were evaluated using the Benefit Finding Scale, the Chinese Version of the Resourcefulness Scale, and the Type 2 Diabetes Stigma Assessment Scale, respectively. A multiple linear regression model was used to analyze the influencing factors of benefit finding among young and middle-aged patients with T2DM. Results: A total of 305 young and middle-aged patients with T2DM were investigated, including 222 males (72.79%) and 83 females (27.21%). There were 231 cases aged 45-59 years, accounting for 75.74%. The scores for benefit finding, resourcefulness, and stigma were (42.86±6.06), (75.12±11.30), and (41.20±10.10), respectively. Multiple linear regression analysis showed that young and middle-aged patients with T2DM who were male (β′=0.088), aged 18-<45 years (β′=0.083), absence of diabetes complications (β′=0.124), and had higher resourcefulness scores (β′=0.679) had higher levels of benefit finding, while patients with higher stigma scores (β′=-0.097) had lower levels of benefit finding. Conclusion The level of benefit finding among young and middle-aged patients with T2DM was moderate, and was related to gender, age, diabetes complications, resourcefulness, and stigma.

Objective To explore the impact of number of positive regional lymph nodes (nPRLN) in N1 stage on the prognosis of non-small cell lung cancer (NSCLC) patients. Methods Patients with TxN1M0 stage NSCLC who underwent lobectomy and mediastinal lymph node dissection from 2010 to 2015 were screened from SEER database (17 Regs, 2022nov sub). The optimal cutoff value of nPRLN was determined using X-tile software, and patients were divided into 2 groups according to the cutoff value: a nPRLN≤optimal cutoff group and a nPRLN>optimal cutoff group. The influence of confounding factors was minimized by propensity score matching (PSM) at a ratio of 1 : 1. Kaplan-Meier curves and Cox proportional hazards models were used to evaluate overall survival (OS) and lung cancer-specific survival (LCSS) of patients. Results A total of 1316 patients with TxN1M0 stage NSCLC were included, including 662 males and 654 females, with a median age of 67 (60, 73) years. The optimal cutoff value of nPRLN was 3, with 1165 patients in the nPRLN≤3 group and 151 patients in the nPRLN>3 group. After PSM, there were 138 patients in each group. Regardless of before or after PSM, OS and LCSS of patients in the nPRLN≤3 group were superior to those in the nPRLN>3 group (P<0.001). N1 stage nPRLN>3 was an independent prognostic risk factor for OS [HR=1.52, 95%CI (1.22, 1.89), P<0.001] and LCSS [HR=1.72, 95%CI (1.36, 2.18), P<0.001]. Conclusion N1 stage nPRLN>3 is an independent prognostic risk factor for NSCLC patients in TxN1M0 stage, which may provide new evidence for future revision of TNM staging N1 stage subclassification.

OBJECTIVE: To analyze the clinical phenotype and pathogenic mechanism of the ARSL gene variant in a fetus with nasal bone aplasia. METHODS: A 34-year-old pregnant woman who attended Quzhou Maternal and Child Health Care Hospital on January 3, 2023 was selected as the study subject. Whole exome sequencing (WES) was performed on the fetus. Bioinformatics analysis was carried out to identify and prioritize candidate gene variants, followed by Sanger sequencing for familial validation. A mutant plasmid expression vector was constructed and subsequently transfected into HEK293T cells to preliminarily investigate the pathogenetic mechanism of the identified variant. Additionally, a comprehensive review of literature was conducted to systematically summarize the associated clinical phenotypes. This study was approved by the Medical Ethics Committee of Quzhou Maternal and Child Health Care Hospital (Ethics No.: KY-2023-11). RESULTS: WES revealed that the fetus harbored a c.827del (p.L276Rfs*48) variant of the ARSL gene, for which its mother was heterozygous. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic(PVS1+PM2_Supporting). In vitro cellular function studies demonstrated that this variant can result in a substantial decrease in the expression of mutant mRNA, thereby preventing the production of normal ARSL protein. Clinical phenotypes resulting from ARSL gene variants exhibited considerable diversity, with nasal hypoplasia being the most common manifestation. CONCLUSION The c.827del (p.L276Rfs*48) variant of the ARSL gene can lead to degradation of mRNA via the nonsense-mediated mRNA decay pathway, resulting in reduced levels of ARSL protein. The pathogenetic mechanism underlying the ARSL gene variant may be associated with its haploinsufficiency effect.

Objective: To analyze the association between fine particulate matter (PM2.5) exposure in the air and dyslipidemia among primary school students, in order to provide the evidencebased support for the prevention and control of chronic diseases in children. Methods: The random sampling method was used to select 625 students from two primary schools in Anhui Province and Tianjin City from May to June 2024. Based on the home address, the annual average exposure levels of PM2.5 were obtained in 3 years before investigation, 2 years before investigation, and the past year before investigation. Fasting blood samples were collected for the detection of total cholesterol, triglycerides (TG), highdensity lipoprotein cholesterol and lowdensity lipoprotein cholesterol. Linear regression modeling was used to analyze the association between PM2.5 exposure and dyslipidemia among primary school students. Results: The rate of dyslipidemia among primary school students was 14.72% in the present study. The results of linear regression analysis showed that the TG increased by 0.019(95%CI=0.012-0.025)，0.023(95%CI=0.016-0.030) and 0.021(95%CI=0.014-0.027) mmol/L for every 1 μg/m3 increase of PM2.5 in the past year before investigation, 2 years before investigation and 3 years before investigation respectively (P<0.05). The results of binary Logisitic analysis showed that the risks of dyslipidemia in primary school students were positively correlated with PM2.5 mass concentration in the past year before investigation, 2 years before investigation, and 3 years before investigation [OR(95%CI)=1.06(1.02-1.11), 1.06(1.01-1.12), 1.06(1.01-1.11), P<0.05]. Conclusions PM2.5 exposure is associated with increased risk of dyslipidemia among primary school students. To protect the health of primary school students, effective measures should be taken to improve air quality.

Objective To establish an individualized nomogram model and evaluate its efficacy to provide a possible evaluation basis for the prognosis of lower third and abdominal part of oesophageal adenocarcinoma (EAC). Methods Lower third and abdominal part of EAC patients from 2010 to 2015 were chosen from the SEER Research Plus Database (17 Regs, 2022nov sub). The patients were randomly allocated to the training cohort and the internal validation cohort with a ratio of 7∶3 using bootstrap resampling. The Cox proportional hazards regression analysis was used to determine significant contributors to overall survival (OS) in EAC patients, which would be elected to construct the nomogram prediction model. C-index, calibration curve and receiver operating characteristic (ROC) curve were performed to evaluate its efficacy. Finally, the efficacy to evaluate the OS of EAC patients was compared between the nomogram prediction model and TNM staging system. Results In total, 3945 patients with lower third and abdominal part of EAC were enrolled, including 3475 males and 470 females with a median age of 65 (57-72) years. The 2761 patients were allocated to the training cohort and the remaining 1184 patients to the internal validation cohort. In the training and the internal validation cohorts, the C-index of the nomogram model was 0.705 and 0.713, respectively. Meanwhile, the calibration curve also suggested that the nomogram model had a strong capability of predicting 1-, 3-, and 5-year OS rates of EAC patients. The nomogram also had a higher efficacy than the TNM staging system in predicting 1-, 3-, and 5-year OS rates of EAC patients. Conclusion This nomogram prediction model has a high efficiency for predicting OS in the patients with lower third and abdominal part of EAC, which is higher than that of the current TNM staging system.

Objective To investigate the effect of mulberry anthocyanin on the morphology and func-tion of vascular endothelial cells(VEC)and its possible mechanism at the level of autophagy.Methods VEC were cultured in vitro and divided into 5.5/0 mmol/L control group,11/0.125,22/0.250,33/0.500,44/1.000,55/2.000 mmol/L high glucose/high fat groups.The cell functional levels and autophage levels in each group were detected.The optimal high glucose/high lipid concentration was selected as the VEC function inju-ry model group.10,25,50 μmol/L mulberry anthocyanins were added into the model group for processing and divided into the low,middle and high concentrations of mulberry anthocyanin groups.The effects of mulberry anthocyanin on the morphology,function and autophagy of VEC in high sugar and high fat stress were ob-served.Then the autophagy regulator(rapamycin)was added to study its action mechanism.HE staining was used to observe the number and morphology of cells,the CCK-8 assay was used to detect the viability of VEC,the flow cytometry was used to detect the level of reactive oxygen species(ROS)in VEC,the Western blot was used to detect the expression level of Beclin-1 and p62 proteins in VEC,and the kit method was used to detect the level of nitric oxide(NO)and endothelin-1(ET-1)in VEC.Results Compared with the control group,the number and morphology of cells in the middle and high concentrations of high glucose/high fat groups were changed,the cell viability,p62,NO levels were significantly decreased(P<0.05),while the ROS,ET-1,and Beclin-1 expression levels were increased significantly(P<0.05).Compared with the model group,the number of cells in the mulberry anthocyanin groups was increased,morphology was improved,the cellular viability,p62 and No levels were significantly increased,and ROS,Beclin-1 and ET-1 levels were significantly decreased(P<0.05).Compared with the high concentration mulberry anthocyanin group,the cells number was decreased af-ter adding rapamycin,the morphology changed to be irregular,the NO level was decreased,and the ET level was increased(P<0.05).Compared with the control group,the p-phosphatidylinositol 3-kinase(PI3K)and p-protein kinase B(Akt)relative expression levels in the model group were significantly decreased(P<0.05);compared with the model group,the p-PI3K and p-Akt relative expression levels in the high concentration mulberry anthocyanin group were significantly increased(P<0.05).Conclusion Mulberry anthocyanin could in-hibit autophagy by activating the PI3K/Akt/mammalian target of rapamycin(mTOR)signaling pathway and improve the morphology and function of VEC under high glucose and lipid stress.

BackgroundCognitive function is closely related to an individual's quality of life and social functioning， with approximately 20%~35% of patients with depressive disorder experiencing some degree of cognitive impairment even after clinical symptom remission. Existing evidence suggests that tACS can improve specific cognitive domains， such as memory function， while its effects on other cognitive dimensions， such as executive functioning， attention， and information processing speed， remain unclear. ObjectiveTo explore the effects of tACS on the multidimensional cognitive functions and emotional problems of patients with depressive disorder， thus to provide references for the treatment of depressive disorder. MethodsForty-nine patients with depressive disorder who were hospitalized in the Fourth People's Hospital of Wuhu from November 2022 to October 2024 and met the diagnostic criteria for depressive disorder outlined in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， were selected as study participants. Subjects were randomly divided into study group （n=23） and control group （n=26） based on Microsoft Excel. Both groups received sertraline treatment. The initial dose was 50 mg/day， which gradually titrated upward based on individual variability， drug tolerance， and therapeutic response， with a maintenance dose ranging from 100 to 200 mg/day. In addition， the study group underwent tACS therapy for 4 weeks， with 5 sessions per week， each lasting 20 minutes. The control group received sham stimulation， in which the stimulus was interrupted after the first 30 seconds. At baseline， the 4^th week， and the 12^th week of treatment， patients were assessed using the Hamilton Depression Scale-17 item （HAMD-17）， Hamilton Anxiety Scale （HAMA）， and MATRICS Consensus Cognitive Battery （MCCB）. ResultsRepeated measures analysis of variance indicated that both the time effect and the time×group interaction effect for HAMD-17 scores were statistically significant between the two groups （F=260.437， 25.309， P<0.01）. At week 12 of treatment， the HAMD-17 score in the study group was lower than that in the control group （t=4.236， P<0.01）. For HAMA scores， the time effect， group effect， and time×group interaction effect were all statistically significant between the two groups （F=248.082， 4.506， 9.500， P<0.05 or 0.01）. At weeks 4 and 12， study group reported lower HAMA scores compared with control group （t=4.580， 2.608， P<0.05 or 0.01）. Regarding the MCCB scores for attention/vigilance， verbal learning， and overall composite， the time effect， group effect， and time×group interaction effect were all statistically significant between the two groups （F=70.331， 27.882， 51.679， 5.560， 10.948， 7.860， 8.490， 3.874， 5.025， P<0.05 or 0.01）. After intervention， the study group showed significantly higher MCCB scores for attention/vigilance， verbal learning， and overall composite at both week 4 （t=-2.149， -3.530， -2.740， P<0.05） and week 12 （t=-3.534， -3.576， -3.838， P<0.01） when compared to the control group. ConclusionThe combined tACS and sertraline therapy may demonstrate superior efficacy to pharmacotherapy alone in the short term for improving attention/vigilance， verbal learning， overall cognitive function， and anxiety symptoms in patients with depressive disorders. Based on the 12-week outcomes， the combined tACS and sertraline therapy not only sustaine its previously observed advantages in improving cognitive domains and anxiety symptoms， but also demonstrate potentially superior efficacy over monotherapy in alleviating depressive symptoms. ［Fund by Clinical Medical Research Transformation Special Project of Anhui Province （number， 202204295107020065）］
