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 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.

Objective:To detect the biological markers related to Alzheimer's disease(AD)in the peripheral blood of AD patients,and to explore the activities and levels of the antioxidant function indexes and the expressions of related genes and proteins in the blood of AD patients and the changes after intervention of selenium-rich food.Methods:The Mini-Mental State Examination(MMSE)combined with electroencephalogram or brain CT and clinician diagnosis were used for screening AD.Fifty-six elderly patients with AD aged 75-90 years old were selected.Among them,28 cases were selected as normal diet group for AD(AD group),and 28 cases were selected as dietary selenium intervention group(Se-AD group).The patients in Se-AD group were given daily dietary selenium supplementation(increaseing dietary selenium by 15-20 μg per day)for 3 months.Meanwhile,30 people with the same age were selected as healthy control group.The activities of serum superoxide dismutase(SOD),cholinesterase(CHE),and glutathione peroxidase(GSH-Px)and the levels of serum malondialdehyde(MDA),homocysteine(Hcy),and nitric oxide(NO)as well as reagent kit the levels of serum β-amyloid protein(Aβ),and microtubule-associated protein(Tau)and phosphorylated microtubule-associated protein(p-Tau)of the subjects in various groups were detected by and enzyme-linked immunosorbent assay(ELISA)method;the expression levels of apolipoprotein E4(ApoE4),presenilin 1(PS1),presenilin 2(PS2),cysteinyl aspartate specific proteinase 3(Caspase3),sorting associated protein receptor 1(SORL1),β-site amyloid precursor protein cleaving enzyme 1(BACE1),hypoxia-inducible factor 1(HIF1),nuclear factor-kappa B(NF-κB),β-amyloid precursor protein(APP),protein kinase C(PKC),and Aβ mRNA in peripheral blood of the subjects various groups were detected by real-time fluorescence quantitative PCR(RT-qPCR)method.Results:Compared with healthy control group,the serum SOD activities of the patients in Se-AD group and AD group were significantly decreased(P＜0.05),while serum CHE activity and the levels of MDA and Hcy were significantly increased(P＜0.05);the serum GSH-Px activity of the patients in AD group was significantly decreased(P＜0.05),and the level of NO was significantly increased(P＜0.05).Compared with Se-AD group,serum CHE activity and the level of Hcy of the patients in AD group were significantly increased(P＜0.05).The expression levels of ApoE4,PS1,Caspase3,BACE1,NF-κB and APP mRNA of the patients in Se-AD group and AD group were significantly increased(P＜0.05),and the expression levels of PKC mRNA were significantly decreased(P＜0.05);the expression level of PS2 mRNA of the patients in AD group was significantly increased(P＜0.05),and the expression levels of Aβ mRNA of the patients in Se-AD group and AD group were significantly increased(P＜0.05).Conclusion:The activities of serum SOD,GSH-Px and CHE and the levels of MDA,Hcy and NO,the levels of Aβ,Tau and p-Tau proteins,and the expression levels of ApoE4,PS1,Caspase3,BACE1,NF-κB,PKC,PS2,Aβ and APP mRNA in peripheral blood of the AD patients may vary and can be used for clinical diagnosis of the AD patients.Selenium-rich food can improve AD to some extent,and its mechanism is related to reducing the oxidative damage of brain tissue and decreasing the expression of AD related genes PS2 and Aβ.

Objective:To understand the characteristics of faculty in high-level public health schools in China, and analyze the differences in age, area and school level.Methods:Based on the internet information, the faculty information of 18 high-level public health schools was collected for a descriptive analysis on faculty characteristics.Results:There were 1 642 faculty members in the schools of public health in China, in whom 51.8% were women, 92.8% had doctorate, 32.4% had postdoctoral experience and 56.8% were former students staying to teach.
