Organophosphorus pesticides(OPs)are widely used in global agriculture,and pose a serious threat to ecological environment and human health due to their high environmental persistence and biological toxicity.Colorimetric sensing strategies based on the inhibition of acetylcholinesterase(AChE)have become an important method for detecting OPs because of their simplicity and high specificity.However,the sensitivity is limited by the insufficient catalytic efficiency of traditional nanozymes.In this study,a one-step solvothermal method was used to synthesize polyoxometalate nanoribbons(POM)loaded with gold nanoparticles(Au NPs),named Au-POM.Experimental results showed that Au-POM could catalyze the decomposition of H2O2 in an acidic environment(pH 4.0),demonstrating typical peroxidase-like activity.Based on this,an AChE,choline oxidase(ChOx)and Au-POM nano enzyme cascade catalytic system was constructed.In this system,AChE specifically catalyzed the hydrolysis of acetylcholine(ACh)to choline,and then ChOx mediated the oxidation of choline to produce H2O2.During this process,Au-POM acted as a peroxidase-like enzyme to catalyze the decomposition of H2O2 to generate reactive oxygen species,triggering a specific oxidation reaction of the chromogenic substrate 3,3',5,5'-tetramethylbenzidine(TMB)into oxidized form.When the OP pesticide ethoprophos(EP)was present,it inhibited the activity of AChE and blocked the generation of ACh and H2O2,indirectly inhibiting the oxidation of TMB.The color and absorbance of the solution changed in a concentration-dependent manner.The detection limit of this method for EP was 1.05 μmol/L,and the linear response range was 20-180 μmol/L(R2=0.998).This method was applied to detection of environmental water samples and coriander samples with satisfactory results,providing a reliable technical platform for monitoring of OPs in environment and food.

Objective:
To evaluate the comprehensive intervention effect of lunch for primary and secondary school students in Minhang District, so as to provide a theoretical and practical basis for lunch intervention in school.
Methods:
From October to December 2023, a convenience sampling method was used to select 1 937 students from one primary and secondary school in Minhang District.A comprehensive intervention measure focusing on "reducing oil and salt" for lunch recipe optimization and nutrition education was carried out, and a questionnaire survey was conducted to evaluate the intervention effect three months later. Chi square test and Wilcoxon rank test were used to compare the data before and after the intervention.
Results:
After intervention, the use of cooking oil and salt, the supply of protein and fat in primary and secondary school lunches were reduced, and had no obvious impact on energy and other major nutrients. After intervention, compared to before intervention, the proportion of primary school students who felt that lunch was greasy decreased (8.9%, 6.2%, χ 2=4.35), and the proportion of primary and secondary school students who felt that lunch were delicious decreased significantly (33.2%, 23.2%; 63.9%, 53.5%, χ 2=26.39, 17.52) ( P < 0.05 ). Secondary school students also felt reduced variety of food ingredients (46.9%, 38.3%, χ 2=16.05, P <0.05). In addition, after intervention, the total surplus rate of primary school students meals decreased (7.4%, 4.4%, χ 2=5.73), mainly reflected in the decrease of the surplus rate of staple foods (7.1%, 2.4%, χ 2=17.39), while the surplus rate of vegetable dishes increased ( 16.0 %, 21.2%, χ 2=6.01) ( P <0.05). Although there was no significant change in the total surplus rate of meals for secondary school students, the surplus rate of staple foods decreased (12.9%, 5.4%, χ 2=33.52), while the surplus rates of meat and vegetable dishes increased (11.2%, 26.9%; 17.5%, 33.2%, χ 2=74.26, 61.88) ( P <0.05). After intervention, there was no statistically significant difference in the overweight and obesity rates of primary school students ( χ 2=0.11,0.43) and secondary school students ( χ 2=0.01,0.00) compared to before intervention( P >0.05). After intervention, the lung capacity of primary school students [1 564 (1 269,1 890) mL] and sitting forward flexion [11.3 (7.6, 15.2) cm] increased compared to before intervention [1 522 (1 259, 1 819 ) mL, 10.5 (6.3, 13.5) cm] ( Z =2.20, 4.68, P <0.01), but there was no statistically significant difference in lung capacity and sitting forward flexion of secondary school students before and after intervention ( Z =-0.46, -0.08, P >0.05).
Conclusion
The comprehensive intervention of school lunch has promoted a significant decrease in the use of oil and salt in lunch and improved the quality of recipes, and has a positive impact on the situation of leftover lunch and the health of students to a certain extent.

BACKGROUND:
Neoadjuvant chemoradiotherapy followed by radical surgery has been a common practice for patients with locally advanced rectal cancer, but the response rate varies among patients. This study aimed to develop a ResNet-Vision Transformer based magnetic resonance imaging (MRI)-endoscopy fusion model to precisely predict treatment response and provide personalized treatment.
METHODS:
In this multicenter study, 366 eligible patients who had undergone neoadjuvant chemoradiotherapy followed by radical surgery at eight Chinese tertiary hospitals between January 2017 and June 2024 were recruited, with 2928 pretreatment colonic endoscopic images and 366 pelvic MRI images. An MRI-endoscopy fusion model was constructed based on the ResNet backbone and Transformer network using pretreatment MRI and endoscopic images. Treatment response was defined as good response or non-good response based on the tumor regression grade. The Delong test and the Hanley-McNeil test were utilized to compare prediction performance among different models and different subgroups, respectively. The predictive performance of the MRI-endoscopy fusion model was comprehensively validated in the test sets and was further compared to that of the single-modal MRI model and single-modal endoscopy model.
RESULTS:
The MRI-endoscopy fusion model demonstrated favorable prediction performance. In the internal validation set, the area under the curve (AUC) and accuracy were 0.852 (95% confidence interval [CI]: 0.744-0.940) and 0.737 (95% CI: 0.712-0.844), respectively. Moreover, the AUC and accuracy reached 0.769 (95% CI: 0.678-0.861) and 0.729 (95% CI: 0.628-0.821), respectively, in the external test set. In addition, the MRI-endoscopy fusion model outperformed the single-modal MRI model (AUC: 0.692 [95% CI: 0.609-0.783], accuracy: 0.659 [95% CI: 0.565-0.775]) and the single-modal endoscopy model (AUC: 0.720 [95% CI: 0.617-0.823], accuracy: 0.713 [95% CI: 0.612-0.809]) in the external test set.
CONCLUSION
The MRI-endoscopy fusion model based on ResNet-Vision Transformer achieved favorable performance in predicting treatment response to neoadjuvant chemoradiotherapy and holds tremendous potential for enabling personalized treatment regimens for locally advanced rectal cancer patients.

Aging is an inevitable, physiological process of the human body, leading to deterioration in bodily function and increased susceptibility to various diseases. Effective endogenous therapeutic strategies for anti-aging and related diseases remain limited. Exercise confers multifaceted benefits to physical health by augmenting osteogenic and myogenic processes, enhancing cardiovascular and nervous system function, and attenuating chronic inflammation. Angiogenesis and lymphangiogenesis play pivotal roles in anti-aging, tissue repair, and immune response modulation, underscoring their potential as therapeutic targets for age-related diseases. Modulating angiogenic and lymphangiogenic pathways may provide a promising strategy for mitigating vascular decline and immune system dysfunction associated with aging. Exercise-induced endogenous angiogenesis and lymphangiogenesis can exert beneficial effects on physiological function, thereby representing a potential therapeutic paradigm for combating age-related decline and diseases. This review offers a thorough summary of the present knowledge regarding angiogenesis and lymphangiogenesis induced by exercise, encompassing the underlying mechanisms and the effects in different organs. In addition, it explores the potential of physical activity as a non-pharmacological intervention for anti-aging strategies and disease management, offering novel insights into the intersection of physical activity, aging, and disease progression.

OBJECTIVES:
To compare perioperative and mid-term results of multiple versus single arterial off-pump coronary artery bypass grafting (OPCABG) in patients with impaired left ventricular function.
METHODS:
This study was conducted among 86 patients with a left ventricular ejection fraction (LVEF) <50%, who underwent OPCABG at our hospital between January, 2018 and December, 2021. Of these patients, 22 underwent OPCABG with multiple arterial grafts (multiple graft group) and 64 received a single arterial graft in OPCABG (single graft group). The preoperative, intraoperative, and perioperative data were collected, and the patients were followed up for a mean of 29.28±14.84 months. The perioperative outcomes and follow-up results of the patients were compared, and the factors influencing major adverse cardiovascular events (MACE) were identified using logistic regression. Kaplan-Meier analysis was used to compare the postoperative survival rate without MACE.
RESULTS:
The patients in multiple graft group had a significantly younger age than those in single graft group (P<0.05), but the other baseline data were similar between the two groups (P>0.05). Perioperative mortality, 24-h postoperative drainage volume, length of ICU stay, intubation time, and the incidence of new-onset atrial fibrillation were all similar between the two groups (P>0.05), but the rate of postoperative hypotension was significantly higher in multiple graft group (34.78% vs 11.54%, P=0.009). No significant differences were found in the incidence of MACE or echocardiographic data during the follow-up. Logistic regression identified the female sex (OR: 0.191, 95% CI: 0.049-0.075) and creatinine level (OR: 1.016, 95% CI: 1.000-1.033) as factors affecting postoperative MACE occurrence. Kaplan-Meier analysis showed no significant difference in MACE-free survival rate between the two groups.
CONCLUSIONS
OPCABG with multiple arterial grafts does not increase severe perioperative complications or the risk of mid-term MACE in patients with impaired left ventricular function.

Objective:To investigate the effects of short-term olfactory training and visual stimulation on olfactory recognition function and quality of life in patients following functional endoscopic sinus surgery (FESS).Methods:A total of 80 patients who underwent FESS in the Department of Otorhinolaryngology Head and Neck Surgery at the Affiliated Hospital of Xuzhou Medical University between December 2023 and February 2024 were enrolled in this study. The cohort comprised 67 males and 13 females, aged from 17 to 75 years. Participants were randomly allocated to either a control group ( n=40) or an experimental group ( n=40). The participants in control group received routine postoperative management, including nasal irrigation, oral antibiotics and glucocorticoids, topical budesonide nasal spray, and hypertonic saline solution for 12 weeks. In addition to the standard care, the participants in experimental group underwent olfactory-visual stimulation training starting 24 hours postoperatively, lasting for 2 weeks. The olfactory identification test (OIT), visual analogue scale (VAS) for olfaction and Questionnaire of Olfactory Disorders of Life (QOD-QoL, hereafter referred to as QOD) were administered preoperatively. Follow-up assessments were performed 2 weeks and 3 months postoperatively, with the same tests repeated. Data were analyzed using SPSS 27.0 and GraphPad Prism 7 statistical software. Results:There was no significant difference in preoperative OIT, VAS, and QOD scores between the two groups. The olfactory recognition function of some patients was improved after removing the packing material 24 hours after FESS surgery. The OIT scores of 2 weeks post-surgery were significantly higher than preoperative values in both groups (the experimental group Z=-4.73, P<0.001; the control group Z=-4.73, P<0.001). Participants in both groups showed improvements in olfactory VAS and QOD scores (experimental group Z value was -2.88 and -5.45, P<0.01 and<0.001, respectively; the control group Z value was -4.42 and -5.50, respectively, both P<0.001). However, there was no significant difference in the VAS score between the two groups ( Z=-0.68, P=0.499). The paticipants in experimental group showed greater improvement in OIT and greater reduction in QOD scores compared to the control group ( Z=-2.19, P=0.029; Z=-2.99, P=0.003). There was no significant difference in the decrease of olfactory VAS between the two groups ( Z=-0.02, P=0.988). There were no statistically significant differences of all patients in VAS, OIT and QOD scores at 2 weeks and 3 months after surgery (experimental group Z value was -0.91, -0.90 and -1.43, respectively, all P>0.05; control group Z value was -1.21, -0.84 and -0.91, respectively, all P>0.05). At 3 months post-surgery, the OIT scores in the experimental group were higher, the QOD scores were lower than those in the control group ( Z=-2.89, P=0.004; Z=-2.87, P=0.004). Conclusion:Short-term olfactory-visual stimulation training in the early postoperative period of FESS significantly improves the olfactory recognition function and enhances the quality of life of patients.
