Objective: To explore the relative importance of different food attributes and levels in food decision making of school aged children, and to understand their meal preferences, so as to provide the evidence for formulating precise intervention strategies for dietary behaviours of school aged children. Methods: From May to June 2024, a total of 854 children aged 11 to 15 years old were selected from 2 middle schools (each school in urban and rural areas) in both Hubei Province and Anhui Province by stratified cluster random sampling method to conduct a D-optimal discrete choice experiment. The mixed Logit model was used to analyze children s preference for meal attributes and different levels, and to calculate the relative importance (RI) of attributes and willingness to pay (WTP) in meal choices. Results: The included five food attributes had statistical significance on meal choice of school aged children ( P <0.05). The relative importance of food attributes affecting the meal choices of school aged children in descending order were dining mode ( RI =31.26%), food varieties ( RI =30.56%), cooking method( RI =23.84%), taste( RI =8.06%) and price ( RI =6.27%). Among them, school aged children preferred home cooked meals ( β =0.74) (WTP=86.3 yuan),varied foods(grain/tubers+vegetables+fish, meat, eggs and beans) ( β =0.61) (WTP=71.9 yuan), fried/roasted cooking ( β =0.51) and spicy taste ( β =0.33).Price was negatively correlated with meal choices( β =-0.01) ( P <0.05). Based on residential area and body mass index (BMI), the stratified analysis showed that dining mode was highest in the relative importance for rural children with overweight and obese children ( RI =31.28%,34.17%), both of whom preferred home cooked meals ( β =0.76, 0.91), and meals containing fish, meat, eggs and beans with grain/tubers or grain/tubers and vegetables in terms of food choice (area: β =0.53, 0.53 ; BMI: β =0.55, 0.56) ( P <0.05). Conclusions School aged children have different preferences for different attributes of meals. The quality of school meals should be improved,the cost of buying healthy meals should be reduced,targeted family health education should be carried out,and healthy cooking methods should be advocated.

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）］

Objective:To investigate the expression of miRNA-144 in the peripheral blood of patients with type 2 diabetes foot ulcer (DFU) and its correlation with the pathogenesis of the disease.Methods:A total of 106 patients with DFU admitted to the General Hospital of the Western Theater Command of the Chinese People′s Liberation Army from March 2020 to June 2022 were retrospectively selected as the observation group, and 106 patients with type 2 diabetes mellitus (T2DM) who did not have DFU admitted to our hospital during the same period were selected as the control group. According to the median expression level of miRNA-144 in peripheral blood of DFU patients as the segmentation point, 106 patients in the observation group were divided into low expression group and high expression group. We compared the clinical data of the observation group and the control group, and analyzed the relationship between different levels of miRNA-144 expression and clinical characteristics of DFU patients; A multivariate analysis was conducted on the factors related to the occurrence and development of the disease course in DFU patients, and a column chart model was constructed for model validation.Results:The course of diabetes, fasting blood glucose (FPG), erythrocyte sedimentation rate (ESR), glycosylated hemoglobin (HbA 1c), white blood cell count (WBC), C-reactive protein (CRP), corticotropin releasing hormone (CRH), interleukin-6 (IL-6), adrenaline (E), norepinephrine (NE), cortisol (Cor) and miRNA-144 expression levels in the observation group were significantly higher than those in the control group, while transcutaneous partial pressure of oxygen (TcPO 2), ankle brachial index (ABI), triglyceride (TG) and hemoglobin (Hb) were significantly lower than those in the control group, the difference was statistically significant (all P<0.05). There were statistically significant differences in foot ulcer healing rate, Wagner grading, and ulcer course between the high expression group of miRNA-144 and the low expression group of DFU patients after 8 weeks (all P<0.05). Multivariate regression analysis showed that the duration of diabetes>5 years, HbA 1c>8.5%, TcPO 2<60 mmHg, CRP>10 mg/L, Cor>190 μg/L, and miRNA-144 expression level>35 were independent risk factors for the occurrence of DFU in T2DM patients. The total score of 315 points after constructing the nomogram prediction model for the above factors, and the corresponding probability of occurrence and development of DFU was 72.56%. Conclusions:The expression level of miRNA-144 in the peripheral blood of DFU patients is significantly related to the occurrence and development of the disease course, and the course of diabetes and the changes of HbA 1c, TcPO 2, CRP, Cor levels are independent risk factors for the occurrence and development of DFU, which should be focused on clinically.

The physiological functions of endogenous amyloid-β (Aβ), which plays important role in the pathology of Alzheimer's disease (AD), have not been paid enough attention. Here, we review the multiple physiological effects of Aβ, particularly in regulating synaptic transmission, and the possible mechanisms, in order to decipher the real characters of Aβ under both physiological and pathological conditions. Some worthy studies have shown that the deprivation of endogenous Aβ gives rise to synaptic dysfunction and cognitive deficiency, while the moderate elevation of this peptide enhances long term potentiation and leads to neuronal hyperexcitability. In this review, we provide a new view for understanding the role of Aβ in AD pathophysiology from the perspective of physiological meaning.

Objective:To investigate the distribution and molecular characteristics of Yersinia isolated from diarrhea patients in Jiangsu Province. Methods:From 2017 to 2021, the stool samples of diarrhea patients were collected in Tongshan District of Xuzhou City and Dongtai City of Yancheng City, Jiangsu Province, where the national active monitoring sites of Yersinia enterocolitica, then Yersinia was isolated; meanwhile, suspected Yersinia strains were collected from sentinel hospitals in the province. The DNA of isolated strains was extracted for whole genome resequencing, and the data were uploaded to the EnteroBase database for Yersinia species identification; the original data were cleaned and processed for 16S ribosomal RNA (16S rRNA) gene polymorphism analysis. Five virulence genes (ail, ystA, ystB, yadA, virF) were scanned through the National Center for Biotechnology Information (NCBI) and Pathogen Virulence Factor Database (VFDB), and K-mer Tree was constructed and genomic characteristics were analyzed. Results:From 2017 to 2021, a total of 2 058 stool samples from diarrhea patients were collected, and 57 strains of Yersinia were isolated and identified; meanwhile, two Yersinia strains were collected from the sentinel hospital. Compared with EnteroBase database, 51 strains were identified as Yersinia enterocolitica, 4 strains as Yersinia proxima, 1 strain each as Yersinia aleksiciae, Yersinia massiliensis, Yersinia intermedia and Yersinia canariae. The 16S rRNA gene polymorphism analysis showed that all strains were clustered into 3 groups, which could distinguish Yersinia enterocolitica from other Yersinia. Among the 51 strains of Yersinia enterocolitica, 49 strains were virulence genotype Ⅲ(ail-, ystA-, ystB+, yadA-, virF-), two strains were virulence genotype Ⅱ(ail+, ystA+, ystB-, yadA-, virF-); and 8 other Yersinia strains were virulence genotype Ⅳ (ail-, ystA-, ystB-, yadA-, virF-). K-mer analysis could distinguish Yersinia enterocolitica from other Yersinia, JS-XZ-2020001 strain was far away from other Yersinia enterocolitica isolates, and serotype O8 strains were more concentrated. Conclusions:The clinical isolates of Yersinia enterocolitica from diarrhea patients are mainly Yersinia and other Yersinia co-exist in a small amount in Jiangsu Province, two new Yersinia species ( Yersinia proxima and Yersinia canariae) are discovered. The virulence genotype of Yersinia enterocolitica is mainly type Ⅲ. The 16S rRNA gene polymorphism analysis and K-mer analysis can effectively distinguish Yersinia enterocolitica from other Yersinia.

Objective:To study the effects of Terra Flavausta on diarrhea mice with spleen yang deficiency based on metabonomics. Methods:Totally 30 mice were divided into normal group, model group and Terra Flavausta group according to random number table method. Mice in the model group and Terra Flavausta group were treated by the method of "diet disorder + clearing fire with herbs bitter in flavour and cold in property" to establish the diarrhea model of spleen yang deficiency. After successful modeling, Terra Flavausta group received Zaoxintu Decoction 12.0 g/kg for gavage, while normal group and model group were given equal volume of distilled water for gavage, for consecutive 7 d. The serum metabolites of each mouse were analyzed and identified based on UPLC-Q-Exective-MS. The differential metabolites were characterized by principal component analysis and orthogonal partial least squares discriminant analysis, and the potential biomakers were screened, and the KEGG pathway enrichment analysis was performed. Results:Totally 110 different metabolites were screened under the positive and negative ion mode. Terra Flavausta can effectively reverse the disorder of serum metabolism in diarrhea mice with spleen yang deficiency, and has a significant callback effect on 12 potential biomarkers related to diarrhea with spleen yang deficiency. KEGG pathway enrichment mainly involved HIF-1 signaling pathway, ascorbate and aldarate metabolism, platelet activation, etc. Conclusion:Terra Flavausta may play the effect of warming spleen and relieving diarrhea through down-regulation of L-ascorbic acid affecting HIF-1 signal pathway, ascorbic acid and aldose metabolism pathway, vitamin digestion and absorption pathway, up-regulation of prostaglandins G2 and H2 affecting platelet activation pathway, and down-regulation of jasmonic acid α linolenic acid metabolic pathway.

Objective:To evaluate the safety and feasibility of applying injectable cross-linked sodium hyaluronate isolation gel in radical hypofractionated radiation therapy for prostate cancer.Methods:In this prospective study, patients at Beijing Hospital who were pathologically diagnosed with clinical stage T 1-2N 0M 0 prostatic acinar adenocarcinoma by puncture and underwent radical radiation therapy were included. All patients received ultrasound-guided cross-linked sodium hyaluronate isolation gel injection and image-guided intensity-modulated radiation therapy (IG-IMRT). The prescription dose was moderately hypofractionated, with a prescription dose of 60 Gy in 20 fractions for 5 times a week, once daily, which was delivered to 95% of the planning target volume (PTV) of prostate and seminal vesicle. Analyze the prostate rectal spacing (PRS) at the baseline, on the day of injection, during the radiotherapy, 1 month and 3 months after radiotherapy, changes in rectal volume before and after injection, and incidence of rectum-related side effects. The changes in all indexes before and after injection were analyzed by using t-test. Results:A total of 13 patients were enrolled from March 2022 to February 2023. The isolation gel maintained morphologic stability without significant spatial changes during radiotherapy, and the mid-prostate had the best effect, with PRS up to 1 cm. At 3 months after radiotherapy, the isolation gel was seen to decreased in volume with a certain absorptive capacity. The irradiated volume of rectum was decreased significantly in all patients after gel injection, and the mean volumes of rectal V 60 Gy , V 50 Gy , V 30 Gy , and V 20 Gy before and after injection were 1.923% vs. 0.280%, 10.255% vs. 3.172%, 29.602% vs. 18.800%, and 49.452% vs. 40.259% (all P<0.005). The average values (range) of rectal V 60 Gy , V 50 Gy , V 30 Gy , V 20 Gy decreases were 84.9%( 29% - 100%), 69.6%(27%-100%), 36.3%(0%-75%), and 17.8%(0%-50%), respectively. No grade 3-4 side effects occurred in all patients, and there were no common grade 1-2 rectal side effects such as diarrhea, rectal bleeding, proctitis and anal pain, etc. Only one patient developed grade 1 constipation during radiotherapy. Conclusion:Injection of Chinese made cross-linked sodium hyaluronate isolation gel can significantly reduce the irradiated volume of rectum and the incidence of rectal toxicities in prostate cancer patients undergoing radical radiotherapy.

Objective:To investigate the clinical and genetic characteristics of genetic and metabolic infantile cholestatic hepatopathy (ICH), and to provide evidence for its diagnosis and treatment.Methods:Clinical data and follow-up outcomes of hospitalized children diagnosed with ICH in the Department of Gastroenterology, Children′s Hospital, Capital Institute of Pediatrics from January 2014 to December 2019 were retrospectively analyzed.Among the 80 children, 27 were female and 53 were male, with a mean age of onset of (39±18) days old.Children with confirmed etiology by high-throughput sequencing analysis were included in the genetic metabolic group (44 cases), and those with idiopathic neonatal cholestasis(INC) of unknown etiology after the systematic examination were included in the INC group (36 cases). The t-test or independent sample rank sum test was used to compare the laboratory test results and biochemical indexes.The infection rate of cytomegalovirus was compared by the Chi- square test. Results:(1) A total of 80 cases were included, and 44 cases (55.0%)were confirmed as INC by high-throughput sequencing.Among those with a positive molecular diagnosis, there were 23 cases of citrin deficiency (CD), 10 cases of Alagille syndrome (ALGS), 6 cases of progressive familial intrahepatic cholestasis (PFIC), 2 cases of congenital bile acid synthesis defect, 2 cases of Nieman Pick disease, and 1 case of cystic fibrosis.(2) Serum total bile acid (TBA) and activated partial prothrombin time (APTT) levels in the genetic metabolic group were significantly higher than those in the INC group (all P<0.05). TBA and APTT levels in genetic metabolites were 180.6 (115.5, 271.6) μmol/L and 40.6 (37.1, 45.2) s, respectively, which were 123.3 (98.8, 163.4) μmol/L and 34.8 (31.7, 40.1) s in INC group, respectively.There was no significant difference in the cytomegalovirus infection rate between the 2 groups ( P>0.05). (3)The pathological examination of liver tissue in the genetic metabolic group was worse than that in the INC group, with spot-like and fusion focal-like necrosis, and 5 cases (4 cases of ALGS and 1 case of CD) showed a reduced number of bile ducts in the portal area and lumen stenosis. Conclusions:CD, ALGS and PFIC are the common causes of genetic and metabolic ICH.Fundamental cause of cholestasis should be actively examined in children with cytomegalovirus infection.High-throughput sequencing is of great significance in the accurate diagnosis of ICH.

Copy number variations (CNVs), which can affect the role of long non-coding RNAs (lncRNAs), are important genetic changes seen in some malignant tumors. We analyzed lncRNAs with CNV to explore the relationship between lncRNAs and prognosis in bladder cancer (BLCA). Messenger RNA (mRNA) expression levels, DNA methylation, and DNA copy number data of 408 BLCA patients were subjected to integrative bioinformatics analysis. Cluster analysis was performed to obtain different subtypes and differently expressed lncRNAs and coding genes. Weighted gene co-expression network analysis (WGCNA) was performed to identify the co-expression gene and lncRNA modules. CNV-associated lncRNA data and their influence on cancer prognosis were assessed with Kaplan-Meier survival curve. Multi-omics integration analysis revealed five prognostic lncRNAs with CNV, namely
