Objective: To explore the intervention effects of different exercise modalities on executive function in school aged children, providing references for formulating exercise prescriptions to promote school aged children executive function. Methods: A systematic literature search was conducted using PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang, VIP and CBM to identify studies on the effects of exercises on executive function in school aged children. The search period spanned from the database inception to August 2025. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. Network Meta analysis was performed using Stata 16.0. Results: A total of 51 studies involving 5 710 school aged children and seven modalities of exercises(control group,small ball sports,large ball sports,aerobic exercise,combined exercise,sport game,gymnastic and dance sports) were finally included. Network Meta analysis showed that, in terms of inhibitory control development of school aged children, small ball sports ( SMD =-0.98,95% CI =-1.32 to -0.64 ), large ball sports ( SMD =-0.64,95% CI =-0.91 to -0.36), and mixed sports ( SMD =-0.26,95% CI =-0.50 to -0.02]) were more effective than the control group; in terms of working memory, largeball sports ( SMD =-1.26,95% CI =-1.88 to -0.65) and small ball sports ( SMD =-0.91,95% CI =-1.64 to -0.19) were superior to the control group; in terms of improving cognitive flexibility, large ball sports ( SMD =-1.02,95% CI =-1.28 to -0.76), gymnastics and dance sports ( SMD =-0.80,95% CI =-1.21 to -0.40), and small ball sports ( SMD =-0.75,95% CI =-1.15 to -0.36) were more effective than the control group (all P <0.05). Surface under cumulative ranking curve(SUCRA) showed that small ball sports had the highest value (SUCRA=98.9%) in improving inhibitory control, while large ball sports achieved the highest score(SUCRA=92.6%) in enhancing working memory, and large ball sports also had the highest value(SUCRA=94.7%) in promoting cognitive flexibility. Conclusions For developing inhibitory control in school aged children, small ball sports are recommended as a priority. For enhancing working memory and cognitive flexibility, large ball sports are recommended.

Antibiotic adjuvants offer a promising strategy for restoring antibiotic sensitivity, expanding antibacterial spectra, and reducing required dosages. Previously, compound 15 was identified as a potential adjuvant for Polymyxin B (PB) against multidrug-resistant (MDR) Pseudomonas aeruginosa DK2; however, its clinical utility was hindered by high cytotoxicity, uncertain in vivo efficacy, and an unclear synergetic mechanism. To address these challenges, we synthesized and evaluated a series of novel benzamide derivatives, with A22 emerging as a particularly promising candidate. A22 demonstrated potent synergistic activity to PB, minimal cytotoxicity, improved water solubility, and broad-spectrum synergism of polymyxins against various clinically isolated MDR Gram-negative strains. In vivo studies using Caenorhabditis elegans and mouse models further confirmed the efficacy of A22. Moreover, A22 effectively suppressed the development of PB resistance in Pseudomonas aeruginosa DK2. Mechanistic investigations revealed that A22 enhances polymyxins activity by inducing reactive oxygen species production, reducing ATP levels, increasing NOX activity, and inhibiting biofilm formation, leading to bacterial death. These findings position A22 as a highly promising candidate for the development of polymyxin adjuvants, offering a robust approach to combating MDR Gram-negative bacterial infections.

Objective:To explore the effectiveness of applying the ADDIE (analysis, design, develop, implement, evaluate) Model in clinical teaching for nursing interns in spine surgery department.Methods:Using a convenience sampling method, 44 nursing interns in the Department of Orthopedics at Peking Union Medical College Hospital were selected as the control group from July 2021 to May 2022, and were taught using traditional methods. From July 2022 to May 2023, 45 nursing interns were selected as the observation group, and a teaching team was formed to design a training program based on the five stages of the ADDIE instructional design model. This program was tailored to improve the overall clinical competence of the spinal surgery nursing interns. After training, the teaching effects were evaluated based on knowledge test scores, skills test scores, overall clinical competence, and teaching satisfaction.Results:After the training, the skills test scores in specialized nursing for the observation group were (94.87±1.10) points, higher than the control group's (93.98±1.41) points, with a statistically significant difference ( P<0.01). The observation group also scored higher than the control group in clinical judgment, organizational effectiveness, overall performance, and total score in the Mini-Clinical Evaluation Exercise, with statistically significant differences ( P<0.01). Additionally, the observation group reported higher satisfaction with the teaching plan and methods compared to the control group ( P<0.05) . Conclusions:Clinical teaching for spinal surgery nursing interns based on the ADDIE instructional design model can improve their specialized practical skills and overall clinical competence. The interns also expressed a high level of acceptance for this teaching design model.

Aim To investigate the effect of dipeptidyl peptidase-4 inhibitor(DPP-4i)on serum creatinine(Cr)in patients with type 2 diabetes mellitus(T2DM).Methods A systematic search was performed across data-bases of PubMed,Embase,Cochrane Library and Web of Science,and randomized controlled trials(RCT)of DPP-4i therapy for regulating Cr in T2DM patients was included.A fixed-effect or random-effect model was used for data fitting,heterogeneity was quantitatively evaluated according to the index of I2,and sensitivity analysis and publication bias testing were performed by using the standard methods.Results After searching the database through the system,12 RCTs were included,with a total of 2 276 participants.Due to the potential heterogeneity,a random effect model was used for data fitting.DPP-4i treatment could mildly increase Cr levels in T2DM patients(WMD:0.15 mg/L,95％CI:0.03～0.27,I=1 8％,P=0.02),and the results showed statistical differences.According to sensitivity testing,the results of Meta-analysis were relatively reliable.No publication bias was observed according to Begg's and Egger's tests.Conclusions The use of DPP-4i for hypoglycemic treatment in T2DM patients may result in mild elevation of blood Cr lev-els.Further multicenter studies with larger samples are needed in the future to explore the clinical significance of DPP-4i treatment induced changes in Cr levels.

Objective:To summarize the clinical manifestations, gene variations, diagnosis and treatment of 3 cases with SLC35A2 variations characterized by congenital glycosylation disorder Ⅱm (CDG Ⅱm). Methods:A total of 3 patients admitted to the Department of Pediatrics of Xiangya Hospital of Central South University in China from 2018 to 2020 were examined in detail. The studies till January 2022 were searched with key words of "congenital disorders of glycosylation Ⅱm", " SLC35A2" and "CDG Ⅱm" in both English and Chinese in the databases of China National Knowledge Infrast Ructure (CNKI), Wanfang, Online Mendelian Inheritance in Man and PubMed, and the clinical manifestations, genetic variation, treatments and prognosis of patients with SLC35A2 mutation were summarized. Results:The patients all presented with intractable infantile spasm and global developmental delay, onset in infancy. A variety of antiepileptic treatments had temporary and partial efficacy. Otherwise, proband 2 and 3 presented with abnormal glutamic-pyruvic transaminase and increased platelets. Funduscopy showed dysplasia of the retinal pigment epithelium in both eyes, and they both received D-galactose treatment. A total of 22 relevant case reports, including 99 patients, were collected. The 99 patients all were heterozygous mutations, and a total of 75 different variation sites were reported. The clinical manifestations were characterized by global developmental delay or mental retardation ( n=89), epileptic seizure ( n=75), hypotonia ( n=57), facial deformity ( n=57), skeletal abnormality ( n=50), visual impairment ( n=42), elevated glutamic-pyruvic transaminase ( n=31), gastrointestinal symptoms ( n=28), skin deformity ( n=26), microcephaly ( n=23) and congenital heart disease ( n=12). Craniocerebral magnetic resonance imaging may be normal in the early stage. With age, magnetic resonance imaging may show abnormal white matter signals, brain atrophy, dysplasia of corpus callosum, delayed myelination, enlargement of lateral ventricle, brain stem atrophy and so on. Studies have shown that galactose treatment may be effective. Conclusions:SLC35A2 variants lead to CDG Ⅱm, whose clinical manifestations mainly include epileptic encephalopathy and global developmental delay. Multiple antiepileptic therapies can temporarily or partially control seizures, while oral galactose may improve the clinical symptoms, showing its prospect as a dietary therapy.

To evaluate the clinical effects and pathological characteristics of gastric tumors of fundic gland type treated with endoscopic submucosal dissection (ESD), data of 7 patients who treated by ESD and whose postoperative pathology indicated gastric adenocarcinoma of fundic gland type or gastric oxyntic gland adenoma in Endoscopic Center of Beijing Chao-Yang Hospital of Capital Medical University from August 2018 to June 2022 were collected. The clinical characteristics, surgical complications, preoperative and postoperative pathological data and follow-up data were evaluated. The lesions of the 7 patients were all located at gastric fundus, and were treated by ESD successfully. No bleeding, perforation or other complications occurred during and after the operation. Postoperative pathology showed that tumor cells originated from deep mucosa with an invasive growth pattern. Most of tumor surfaces were covered with normal concave epithelium. Tumors infiltrated into submucosa in 4 patients, and submucosa infiltration depth was more than 500 μm (550 μm) in 1 patient. Immunohistochemistry showed that MUC-6 was diffusely positive, indicating that the tumor originated from the main cell source. The expressions of MUC-2, MUC-5AC, CDX-2, CD10, and CgA were negative in all cases. With the mean follow-up time of 21 months, the ulcer healed well after the operation, with no recurrence. Gastric tumors of fundic gland type have relatively unique biological characteristics, and ESD is the preferred treatment. In addition, the histological characteristics can be used to differentiate from other gastric tumors by immunohistochemistry.

Objective:To investigate the predictive value of serum vascular endothelial growth factor (VEGF), squamous cell carcinoma-associated antigen (SCCAg) and miRNA let-7a in lymph node metastasis and postoperative recurrence in patients with laryngeal cancer.Methods:A total of 82 patients with laryngeal cancer in the Second Central Hospital of Baoding from November 2017 to October 2019 were selected as the research subjects, including 18 cases of lymph node metastasis (metastasis group) and 64 cases of non metastasis (non metastasis group). The blood routine was tested before operation, and the baseline data, serum VEGF, SCCAg and miRNA let-7a levels were compared between the two groups. Logistic regression was used to analyze the related influencing factors of lymph node metastasis in patients with laryngeal cancer. The correlation between serum VEGF, SCCAg, miRNA let-7a levels and clinicopathological characteristics was analyzed. The receiver operating characteristic (ROC)curve was used to analyze the value of each index and the combined diagnosis of lymph node metastasis in patients with laryngeal cancer. After 1 year of follow-up, the serum VEGF, SCCAg and miRNA let-7a levels of patients with or without recurrent laryngeal cancer were compared. ROC curve was used to evaluate the value of VEGF, SCCAg, and miRNA let-7a in predicting the recurrence of laryngeal cancer.Results:There were statistically significant differences in tumor node metastasis (TNM) stage, degree of infiltration, degree of differentiation, serum VEGF, SCCAg, and miRNA let-7a levels between the metastasis group and non metastasis group (all P<0.05). Serum VEGF, SCCAg, miRNA let-7a levels in patients with laryngeal cancer were related to TNM stage, degree of infiltration and degree of differentiation (all P<0.05). The combined diagnosis of serum VEGF, SCCAg and miRNA let-7a levels in the diagnosis of lymph node metastasis in patients with laryngeal cancer showed that the diagnostic sensitivity and specificity were 88.89% and 70.31%, respectively. The serum VEGF and SCCAg levels of patients with recurrence after operation were higher than those without recurrence, and the level of miRNA let-7a was lower than those without recurrence (all P<0.05). The sensitivity and specificity of combined serum VEGF, SCCAg and miRNA LET-7a levels in predicting postoperative recurrence of laryngeal cancer were 72.97% and 91.11%, respectively. Conclusions:VEGF, SCCAg, miRNA let-7a in patients with laryngeal cancer have a certain correlation with clinicopathological characteristics, which can assist in the diagnosis of lymph node metastasis and help clinical prediction of postoperative recurrence in patients with laryngeal cancer, and provide a reference for the formulation of clinical treatment plans.

Objective To compare curative effect between lenvatinib combined with locoregional therapy and locoregional therapy on PD-L1-positive hepatocellular carcinoma patients with type Ⅰ-Ⅲ portal vein tumor thrombus according to Cheng's classification. Methods The patients in lenvatinib combined with locoregional therapy group received orally-administered lenvatinib at a dose of 12 mg qd for patients≥60 kg or 8 mg qd for patients < 60 kg. The locoregional therapy group only received locoregional therapy. We retrospectively analyzed the clinical data and prognosis of two groups. Results The CR+PR were 78.1% and 53.6% in the combination group and locoregional therapy group, respectively (P < 0.05). The response rate, disease control rate and overall survival of the combination group were higher than those in the locoregional therapy group (P < 0.05). Conclusion The curative effect and overall survival of lenvatinib combined with locoregional therapy is better than locoregional therapy on PD-L1-positive hepatocellular carcinoma patients with type Ⅰ-Ⅲ portal vein tumor thrombus according to Cheng's classification.

Objective:Based on the clinical indicators of severe community-acquired pneumonia in emergency department, the early warning indicators of critical condition were constructed.Methods:The general information, vital signs before entering ICU, laboratory indexes and the survival rate in 30 days of 118 patients with community-acquired pneumonia were retrospectively collected in the emergency care unit of Peking Union Medical College Hospital from January to December 2018. The indexes of death patients (24 cases) and alive patients (98 cases) underwent comparative analysis, using ROC curve to predict the clinical outcome and reliable parameters of emergency patients with community-acquired pneumonia. The best cutoff value was determined according to Youden index and then undergoing multiple factors Logistic stepwise regression analysis. Then early warning model of critical degree was finally built.Results:Eleven indicators were used to predict the criticality of patients with acute community-acquired pneumonia, including AVPU (alert, voice, pain, unresponsive) score, Glasgow Coma Scale(GCS), heart rate, pulse oxygen saturation (SpO 2), fraction of inspiration O 2, oxygenation index,potential of hydrogen, blood potassium (K +), bilirubin, urea nitrogen, and C reactive protein, the optimal cutoff values were 2 points, 8 points, 91 times per minute, 0.94, 41%, 81.20%, 7.38, 4.0 mmol/L, 10.90 μmol/L, 2.23 mmol/L, and 41.5 mg/L. Multiple Logistic stepwise regression showed that the independent factors for predicting death were GCS score, SpO 2 and urea nitrogen, and the predictive ability of the early-warning model was 83.7%. Conclusions:GCS score, SpO 2 and urea nitrogen are effective early warning indicators for the severity of severe community-acquired pneumonia in emergency department, which are conducive to the rapid and efficient early identification and treatment of critically ill patients. Therefore, they are worthy of promotion and application in clinical practice.
