ObjectiveTo explore the potential mechanism of Changji'an Formula (肠激安方) on intestinal permeability for rats with diarrhea-predominant irritable bowel syndrome (IBS-D) of liver depression and spleen deficiency syndrome by the microRNA-29b-3p (miR-29b-3p)/tumor necrosis factor receptor-associated factor 3 (TRAF3)/nuclear factor-κB (NF-κB)/myosin light chain kinase (MLCK) axis. MethodsTwenty-four 1-day-old male Sprague-Dawley (SD) suckling rats were selected, and the IBS-D rat model of liver depression and spleen deficiency syndrome was established via a three-factor method,i.e. maternal separation plus acetic acid stimulation and restraint stress, for 6 consecutive weeks. After successful modeling, the rats were randomly divided into a model group, pinaverium bromide group, low-dose and high-dose Changji'an Formula groups, with 6 rats in each group. Another 6 age-matched non-modeled SD rats were included as the control group. The low-dose and high-dose Changji'an Formula groups were given intragastric administration of Changji'an Formula solution at doses of 16.74 g/(kg·d) and 33.48 g/(kg·d), respectively; the pinaverium bromide group received intragastric administration of pinaverium bromide tablets at 0.018 g/(kg·d); and the control group was given distilled water at 10 ml/(kg·d) via intragastric gavage. The intervention was conducted once daily for 14 consecutive days. After the gavage treatment, the fecal water content of rats in each group was measured. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of intestinal permeability indicators, including D-lactic acid (D-LA), diamine oxidase (DAO), and lipopolysaccharide (LPS). Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to determine the mRNA expression levels of miR-29b-3p, TRAF3, tumor necrosis factor-α (TNF-α), p65, p50, and MLCK in colonic tissues. Western Blot analysis was employed to detect the protein expression levels of TRAF3, TNF-α, p65, phosphorylated p65 (p-p65), MLCK, myosin light chain (MLC), phosphorylated MLC (p-MLC), and tight junction proteins including junctional adhesion molecule-A (JAM-A), Occludin, and Claudin-1 in colonic tissues. ResultsCompared with the control group, the model group exhibited significantly increased fecal water content and serum levels of D-LA, DAO, and LPS, along with decreased protein expression levels of JAM-A, Occludin, and Claudin-1 in colonic tissues (P<0.05 or P<0.01). Additionally, in the model group, the mRNA expression levels of miR-29b-3p, TNF-α, p65, p50, and MLCK in colonic tissues were up-regulated, while the mRNA and protein expression levels of TRAF3 were down-regulated; the protein levels of TNF-α and MLCK, as well as the ratios of p-p65/p65 and p-MLC/MLC, significantly elevated (P<0.01). Compared with the model group, all treatment groups showed reduced fecal water content and serum levels of D-LA, DAO, and LPS, along with down-regulated mRNA expression levels of miR-29b-3p, TNF-α, p65, p50, and MLCK, and up-regulated TRAF3 mRNA expression in colonic tissues. Moreover, the pinaverium bromide group and high-dose Changji'an Formula group presented increased protein levels of Occludin, Claudin-1, and TRAF3, as well as decreased protein levels of TNF-α and MLCK, and reduced ratios of p-p65/p65 and p-MLC/MLC in colonic tissues (P<0.05 or P<0.01). Compared with the low-dose Changji'an Formula group, the high-dose group had lower fecal water content and serum levels of DAO and LPS (P<0.01). In comparison with the pinaverium bromide group, the high-dose Changji'an Formula group showed a significant decrease in serum DAO level (P<0.01). ConclusionsChangji'an Formula can reduce intestinal permeability and restore intestinal barrier function in IBS-D rats of liver depression and spleen deficiency syndrome by regulating the miR-29b-3p/TRAF3/NF-κB/MLCK axis.

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.

The neonatal mammalian heart has a remarkable regenerative capacity, while the adult heart has difficulty to regenerate. A metabolic reprogramming from glycolysis to fatty acid oxidation occurs along with the loss of cardiomyocyte proliferative capacity shortly after birth. In this study, we sought to determine if and how metabolic reprogramming regulates cardiomyocyte proliferation. Reversing metabolic reprogramming by carnitine palmitoyltransferase 1 (CPT1) inhibition, using cardiac-specific Cpt1a and Cpt1b knockout mice promoted cardiomyocyte proliferation and improved cardiac function post-myocardial infarction. The inhibition of CPT1 is of pharmacological significance because those protective effects were replicated by etomoxir, a CPT1 inhibitor. CPT1 inhibition, by decreasing poly(ADP-ribose) polymerase 1 expression, reduced ADP-ribosylation of dual-specificity phosphatase 1 in cardiomyocytes, leading to decreased p38 MAPK phosphorylation, and stimulation of cardiomyocyte proliferation. Our present study indicates that reversing metabolic reprogramming is an effective strategy to stimulate adult cardiomyocyte proliferation. CPT1 is a potential therapeutic target for promoting heart regeneration and myocardial infarction treatment.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Objective:To explore the molecular mechanism of TCM compound Shengxue Tongbian Granules in improving intestinal injury in septic rats through bioinformatics and experimental validation methods.Methods:The GSE131761 gene set was processed by bioinformatics to screen differential genes, then weighted gene co-expression network analysis (WGCNA) was applied to screen modular genes. The intersection of modular genes and differential genes was taken, and finally, the least absolute shrinkage and selection operator (LASSO) technique was applied to further obtain the key targets of sepsis, which was validated by experiments. Totally 72 SD rats were divided into sham-operation group, model group, dexamethasone group (0.15 mg/kg), Shengxue Tongbian Granules low- (0.3 g/kg), medium- (0.6 g/kg), and high-dosage (1.2 g/kg) groups, with 12 rats in each group. Corresponding drug interventions were administered to each treatment group before and 12 hours after modeling. The sham-operation group and the model group were gavaged daily with equal amounts of saline. Samples were collected after 24 hours. HE staining was used to detect the pathological morphology of intestinal tissues in each group of rats; ELISA was used to detect the levels of TNF-α, diamine oxidase (DAO), IL-6, IL-10, and myeloperoxidase (MPO) in rat serum. Immunohistochemistry was used to detect the protein expressions of MPO and neutrophil elastase (NE/LANE) in intestinal tissue, and Western blot was used to detect the protein expression of peptidyl arginine deaminase (PAD4) in intestinal tissue.Results:Seven final key genes related to sepsis were selected, namely ANXA3, CYP1B1, FCAR, LILRA5, PADI4, NOV, and S100A12. Experimental results showed that drug administration alleviated intestinal injury; compared with the model group, the levels of TNF-α, IL-6, MPO, and DAO decreased in the Shengxue Tongbian Granules high-dosage group ( P<0.05), the levels of ELANE and MPO were reduced in Shengxue Tongbian Granules low-, medium-, and high-dosage groups ( P<0.05), and PAD4 expression was reduced in the Shengxue Tongbian Granules high-dosage group ( P<0.05). Conclusion:Shengxue Tongbian Granules can improve the intestinal injury of septic rats, and the mechanism may be related to the inhibition of PAD4-mediated formation of NETs and the improvement of inflammatory response.

ObjectiveTo understand the visual environment sanitation in primary and secondary school classrooms in Minhang District, Shanghai, and to investigate the factors affecting the decline in students’ visual acuity. MethodsIn 2020, among all the primary and secondary schools in Minhang District, according to different types of classroom structures, levels, orientations, unilateral lighting, and bilateral lighting, a total of 20 231 students from 674 classrooms in primary and secondary schools were selected through stratified cluster sampling. Each monitored classroom was regarded as a research unit, and the naked eye vision of students was tested using a standard logarithmic vision chart during the 2020 and 2021 academic years. The change in average visual acuity between the two measurements was taken as the dependent variable, and the visual environment indices were considered as independent variables. The relationship between classroom visual environment indices and the decline in students’ naked eye vision was analyzed. ResultsThe qualification rates for per capita classroom area, window to floor area ratio, average illuminance of the blackboard, uniformity of blackboard illuminance, average illuminance of the desks, uniformity of desk illuminance, lighting coefficient of classroom, blackboard reflection ratio, back wall reflection ratio, and distance between lamps and desks were 79.53%, 88.58%, 46.74%, 70.33%,64.69%, 80.86%, 71.81%, 20.30%, 1.63%, and 97.53%, respectively. The average naked eye vision of primary and secondary school students in the 2020 academic year was 4.75±0.37 (right eye) and 4.76±0.37 (left eye), while in the 2021 academic year, it was 4.70±0.39 (right eye) and 4.71±0.38 (left eye). There was a significant decrease in the naked eye vision of primary and secondary school students in the 2021 academic year compared to that of 2020 (P<0.05). Univariate linear regression analysis showed a significant correlation between grade, average illuminance of the blackboard, average illuminance of the desks, uniformity of desk illuminance, lighting coefficient, and distance between lamps and desks, and the decline of students’ naked eye vision within one academic year (P<0.05). After adjusting for grade, multiple linear regression analysis revealed a significant correlation between the average illuminance of the blackboard, uniformity of desk illuminance, lighting coefficient, and distance between lamps and desks, and the decline of students’ naked eye vision within one academic year (P<0.05). Higher average illuminance of the blackboard, uniformity of desk illuminance, lighting coefficient, and distance between lamps and desks were protective factors for naked eye vision. ConclusionThe visual environment of primary and secondary school classrooms in Minhang District is a matter of concern. Average illuminance of the blackboard, uniformity of desk illuminance, lighting coefficient, and distance between lamps and desks are related to the degree of visual impairment in students over a year.
