Objective: To evaluate the efficacy and prognosis of loop cutaneous ureterostomy (LCU) in the treatment of primary obstructive megaureter (POM) with severe hydroureteronephrosis (HUN) in infants under 1 year of age，so as to provide reference for infants unsuitable for stage-Ⅰ ureteral reimplantation. Methods: A retrospective analysis was conducted on 12 infants with POM and severe HUN treated with LCU in our hospital during Jan.2019 and Dec.2023.The clinical characteristics，surgical techniques，indications，postoperative complications，stage-Ⅱ surgical approaches，and follow-up outcomes were summarized. Results: All operations were successful，with an average operation time of (37.08±7.53) min (6 left-sided LCU and 6 right-sided LCU).During the mean follow-up of (10.12±2.70) months，all infants showed clinical improvement，with complete resolution or significant alleviation of hydronephrosis，reduced ureteral diameter，and increased renal cortical thickness.Complications included asymptomatic bacteriuria in 3 cases (25%) and urinary tract infection (UTI) in 1 case，all resolved with oral antibiotics.Four cases developed peristomal rashes，which improved with topical treatment.Eleven infants underwent stage-Ⅱ Cohen ureterovesical reimplantation at a mean age of (15.20±2.07) months.Notably，27.3%(3/11) required ureteral tailoring or plication during reimplantation，which reduced the risk of ischemic necrosis from excessive trimming.During the follow-up of (22.17±13.93) months，hydronephrosis and renal function improved，and no febrile UTI or bladder dysfunction occurred. Conclusion: LCU is a safe and effective method，which can provide adequate urinary drainage，relieve obstruction，stabilize renal function，and allow time for ureteral maturation and renal parenchymal recovery.LCU also facilitates subsequent stage-Ⅱ surgery by reducing ureteral dilation.

Abstract The application of artificial intelligence (AI) technology in the field of mental health is becoming increasingly extensive and in depth. As digital natives, children and adolescents are experiencing a significant shift in the prevention, identification, and intervention of their mental health issues:transitioning from traditional models to intelligent and digital approaches. At present, the mental health status of children and adolescents in China is not optimistic, with emotional disorders such as depression and anxiety showing a trend toward younger onset. However, the traditional mental health service model faces multiple challenges, including a shortage of professionals, low service accessibility, and difficulties in early identification. The study systematically reviews the current application status of AI technology in the mental health field of children and adolescents, including the latest progress in screening, assessment, intervention, and treatment; deeply analyzes the key challenges currently faced; and proposes suggestions for promoting the deep integration of AI technology and mental health services for children and adolescents, providing theoretical support and practical guidance for the intelligent, precise, and inclusive development of mental health services.

The pathogenesis theory of"spleen deficiency and stasis toxin"in gastric cancer holds that spleen is the source of generation and transformation of qi and blood,that spleen deficiency is the internal basis of disease and throughout the disease.Stasis toxin is based on spleen deficiency,which is the fundamental pathogenesis of gastric cancer.In the pathological process of gastric cancer,a variety of metabolic substances in tumor cells and tumor microenvironment,mainly glucose metabolic reprogramming,undergo metabolic changes to reconstruct the phenotype and function of tumor-related macrophages,which is consistent with the pathogenesis theory of"spleen deficiency and stasis toxin".Therefore,this article focused on the reprogramming of glucose metabolism in tumor microenvironment to drive the phenotypic remodeling of tumor-related macrophages,explored the scientific connotation of the pathogenesis theory of"spleen deficiency and stasis toxin"of gastric cancer,and provided references for the theoretical and clinical research on the treatment of gastric cancer by TCM.

Objective:To explore the diagnostic value of whole blood cell parameters logistic regression model for radiation injury on radiation workers by comparing the differences of whole blood cell parameters between occupational radiation injury population and occupational health examination population.Methods:In February 2023, 184 radiation workers who received occupational health examinations in our hospital and occurrenced chromosome aberration from July 2021 to July 2022 were retrospectively selected as the radiation injury group. And other 184 radiation workers encountered in the same period without chromosome aberration occurrence were selected as the control group. Collected whole blood cell parameters from two groups of research subjects, conducted comparative analysis, constructed a logistic regression model, and evaluated the diagnostic value of the logistic regression model for radiation injury on radiation workers by receiver operating characteristic curve (ROC) and area under curve (AUC) . In addition, with the same standard, 60 radiation workers with chromosome aberration and 60 radiation workers without chromosome aberration from August 2022 to January 2023 were included in the validation queue to validate the logistic regression model.Results:Neu_X, Neu_Y, Neu_Z, Lym_X, Lym_Y, Lym_Z, Mon_X, Mon_Y, Mon_Z, Micro, MCHC in the radiation injury group were significantly higher than those in the control group, and the difference was statistically significant ( P<0.05) . And MCV and Macro in the radiation injury group were lower than those in the control group, and the difference was statistically significant ( P<0.05) . Moreover, logistic regression analysis showed that Lym_X, Lym_Y, Lym_Z, MCHC, Micro were all independent risk factors for diagnosing radiation injury on radiation workers ( OR=1.08、1.02、0.99、1.06、51.32, P<0.05) . ROC curve analysis showed that the AUC, sensitivity, specificity, and accuracy of the logistic regression model based by Lym_X, Lym_Y, Lym_Z, MCHC and Micro in diagnosing radiation injury on radiation workers were 0.80, 85.9%, 65.8% and 75.9% respectively. The validation queue verified the logistic regression model and the AUC, sensitivity, specificity, and accuracy of the logistic regression model were 0.80, 81.7%, 71.7% and 76.7% respectively, the model fitted well. Conclusion:Radiation damage can cause changes in multiple whole blood cell parameters of radiation workers. The logistic regression model based by Lym_X, Lym_Y, Lym_Z, MCHC and Micro showed good diagnosis ability and can be used for the screening of radiation injury on radiation workers.

Objective To analyze the correlation of interferon-induced protein with tetratricopeptide repeats 1(IFIT1)with immune infiltration and prognosis of ovarian cancer(OC).Methods GEO database was employed to select the tumor immune related genes,and Kaplan-Meier and Prognoscan databases were used to identify the genes significantly associated with OC prognosis.The differential expression of IFIT1 between OC tissue and normal tissue were confirmed with GEPIA,Human Protein Atlas,and Timer databases.The expression level of IFIT1 in OC tissues with different grades and stages were analyzed in the UALCAN database.In addition,based on David database,GO enrichment analysis was used to analyze the interacting genes and proteins of IFIT1 in the String and Genemania databases.Timer and Tisidb databases verified the correlation between IFIT1 and immune cells mutually.Finally,after IFIT1 knockdown xenograft model was constructed based on lentiviral vector of IFIT1 shRNA,the tumor growth was observed in the transplanted nude mice,and infiltration of neutrophils was observed with immunohistochemical assay.Results FIT1,a tumor immune gene,selected from the GEO database,Kaplan-Meier and Prognoscan databases,was negatively correlated with the OC prognosis.GEPIA,Human Protein Atlas,Timer database,and UALCAN database indicated that the expression level of IFIT1 was significantly higher in the OC tissues than the normal ovarian tissues,and had no obvious correlation with tumor stage and grade.Analysis in String,Genemania,and David database found the interaction genes and proteins of IFIT1 were enriched in activation of 2'-5'oligonucleotide synthase,virus defense,and innate immunity,and other processes.The Timer database presented that IFIT1 was positively correlated with the infiltration of CD8+T cells,B cells,dendritic cells,neutrophils,and macrophage in OC,with neutrophils having the most significant correlation.Tisidb and GSCA also confirmed the positive correlation between IFIT1 and neutrophil infiltration in OC(P＜0.05).RT-qPCR and Western blotting confirmed that IFIT1 knockdown resulted in suppressed tumor growth in OC cells xenograft nude mice(P＜0.05)and reduced neutrophil infiltration in the xenograft tissues.Conclusion IFIT1 may influence the malignant progression of OC by promoting neutrophil infiltration.

Objective:To investigate the characteristics of obesity in adolescents with major depressive disorder (MDD) and its association with the depressed severity.Methods:A total of 278 adolescents with MDD were recruited according to the inclusion and exclusion criteria. Their demographic data were collected and 24-item Hamilton depression scale (HAMD-24) was used to evaluate their severity of depression. According to the body mass index (BMI) classification standard of adolescents in China, all subjects were classified into four groups(wasting group, normal BMI group, overweight group and obesity group). SPSS 26.0 statistical software was used for data analysis. The Kruskal-Wallis test and the Chi-square test were separately used for the comparison of the four groups.Spearman correlation was used to explore the relationship between BMI and HAMD-24 scores and severity.Results:Among 278 adolescents with MDD, the prevalence of body abnormality was 32.4% (90/278), among which wasting, overweight and obesity were 9.0% (25/278), 14.4% (40/278) and 9.0% (25/278) respectively. There were statistically differences in gender ( χ2=17.018, P<0.001), HAMD-24 scores ( H=9.427, P=0.024) and depressed severity( H=8.508, P=0.037) among the four groups. Multiple comparisons showed that there were only statistically differences between obesity group and normal BMI group, that was the prevalence of obesity in males was higher than that in females ( χ2=13.631, P<0.001), and the level in HAMD-24 scores ( Z=2.956, P=0.003) and depressed severity ( Z=2.832, P=0.005) was lower in obesity group than that in normal BMI group.Spearman correlation analysis showed that BMI was negatively correlated with HAMD-24 scores ( r=-0.162, P=0.007). Conclusion:There is gender difference in obesity rates among the adolescent patients with first-episode untreated MDD. And the obese patients are less depressed than those with normal BMI.

Objective To investigate the effect of rehabilitation training combined with acupuncture ( RTA) on upper limb function of stroke patients by Kinect. Methods Stroke patients with upper limb dysfunction werrandomly divided into control group (rehabilitation training) and treatment group ( RTA), with 15 cases in each group. The modified Barthel Index ( MBI), Fugl Meyer assessment ( FMA), and Wolf motor function test (WMFT) were compared between two groups before and after treatment. The changes in motor time ( MT), motor unit number (MUN), index of curvature (IC), elbow flexion angle (EFA), shoulder flexion angle (SFA),and shoulder adduction angle ( SAA) during three actions, namely, placing forearm on the table, extending elbow and drinking water, were evaluated by Kinect and then compared between two groups before and after treatment. Results After 6 weeks of intervention, the scores of MBI, FMA, WMFT and elbow extension in treatment group were higher than those in control group (P<0. 05). The scores of MBI, FMA, WMFT and three actions after treatment were higher than those before treatment (P<0. 05). For three actions, the improvement of MT, MUN, IC, EFA, SFA, and SAA in treatment group were better than those in control group ( P< 0. 05). Compared with pre-treatment, for the action of forearm placement on the table and elbow extension, both treatment group and control group showed an increase in EFA (P<0. 05), and a decrease in MT, MUN, IC, SFA and SA (P<0. 05). For the action of drinking water, both treatment group and control group showed an increase in EFA and SAA (P< 0. 05), and a decrease in MT, MUN, IC and SAA ( P< 0. 05). Conclusions RTA can improve the upper limb function of stroke patients. Kinect can accurately reflect the changes in upper limb function of stroke patients, and it is suitable for clinical work.

The gut microbiota is mainly composed of a diverse population of commensal bacterial species and plays a pivotal role in the maintenance of intestinal homeostasis, immune modulation and metabolism. The influence of the gut microbiota on solid organ transplantation has recently been recognized. In fact, several studies indicated that acute and chronic allograft rejection in small bowel transplantation (SBT) is closely associated with the alterations in microbial patterns in the gut. In this review, we focused on the recent findings regarding alterations in the microbiota following SBTand the potential roles of these alterations in the development of acute and chronic allograft rejection. We also reviewed important advances with respect to the interplays between the microbiota and host immune systems in SBT. Furthermore, we explored the potential of the gut microbiota as a microbial marker and/or therapeutic target for the predication and intervention of allograft rejection and chronic dysfunction. Given that current research on the gut microbiota has become increasingly sophisticated and comprehensive, large cohort studies employing metagenomic analysis and multivariate linkage should be designed for the characterization of host-microbe interaction and causality between microbiota alterations and clinical outcomes in SBT. The findings are expected to provide valuable insights into the role of gut microbiota in the development of allograft rejection and other transplant-related complications and introduce novel therapeutic targets and treatment approaches in clinical practice.

Objective:To investigate the dynamic changes of the luminal microbiota in the jejunum following administration of proton pump inhibitors (PPIs) in a rat model.Methods:Rats were randomized into six groups (n =6 each group).A group of rats were sacrificed just after anesthesia as normal control (0 d) and,other five groups were continuously administered with omeprazole (10 mg/kg twice daily,intraperitoneally) and were euthanized at 5,9,14,21,28 days following the treatment,respectively.Total DNA in the luminal contents of jejunum was extracted and was used for polymerase chain reaction (PCR) amplification with the primer set targeted the hypervariable V3 region of 16S ribosomal RNA genes.Subsequently,the amplicons were separated by denaturing gradient gel electrophoresis (DGGE).After the gels were stained and photographed,the bands were cut out and sequenced to determine the closest bacterial relatives with the BLAST.The DGGE profiles were analyzed to evaluate the shifts of the microbiota composition and diversity following treatments.Results:Changes of the jejunal microbiotas in rats were observed at 5 and 9 days post PPI administration,as characterized by outgrowth of Streptococcus pneumonia,Clostridium saccharolyticum and Lactococcus garvieae compared to those of the controls (0 d).With time extension of PPI treatment,the mictobiotas significantly shifted toward dysbiotic state,in which the opportunistic pathogens,including Ertterococcus faecalis and Clostridium difficile,were strikingly expanded,especially 21 days later.However,the commensals such as Lactobacillus reuteri and Weissella koreensis were markedly declined in PPI-treated animals compared with the controls.The similarity of the jejunal microbiotas between PPI-treated animals and controls was markedly reduced following PPI treatment,reaching (56.1 ± 16.7) ％ at 28 days.Conclusion:Our data demonstrate that the gastric acid suppression could induce shifts of the jejuna microbiota in a rat model.More importantly,long-term use (＞ 14 d) of PPI could lead to the dysbiosis of the jejunal microbiota,which might be related causally to increased susceptibility to enteric infection.
