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 compare the efficacy and safety of deglycerolized red blood cells (DRBC) and suspended red blood cells (SRBC) based on the propensity score matching (PSM) method, so as to provide evidence for the rational use of DRBC resources in clinical practice. [Methods] A total of 89 patients who received DRBC transfusion and 2 916 patients who received SRBC transfusion in our hospital from January 2023 to September 2024 were included. A 1∶1 nearest neighbor PSM was used to balance covariates such as gender, age, and body mass index (BMI). The changes of hemoglobin (Hb), red blood cell (RBC) count, hematocrit (HCT), and inflammatory markers such as white blood cell (WBC) count, neutrophil (NE) count, C-reactive protein (CRP), and Interleukin-6(IL-6) in the last 72 hours after transfusion were analyzed by SPSS 26.0 and R software to evaluate clinical efficacy and transfusion safety. [Results] The baseline of the two groups was balanced after PSM (P>0.05). There was no significant difference in the total effective rate between the DRBC group (80.9%) and the SRBC group (86.5%) (P>0.05). In the SRBC group, WBC (×10 /L) increased from 9.634±6.742 to 10.147±6.835, CRP (mg/dL) increased from 5.468±4.647 to 6.174±6.114, and IL-6(pg/mL) decreased from 213.733±587.191 to 157.255±552.626. In the DRBC group, WBC (×10 /L) decreased from 11.123±7.880 to 11.011±8.549, CRP (mg/dL) decreased from 5.729±4.761 to 5.326±4.466, and IL-6(pg/mL) decreased from 238.806±639.060 to 152.255±266.558. Compared with the before treatment, the differences between the SRBC group and DRBC group were not statistically significant (P>0.05). Among all patients included in the statistics, the overall incidence of transfusion adverse reactions was 0.205% (6/2 916) in the SRBC group, and no adverse reactions occurred in the DRBC group. The incidence in the SRBC group was higher than that in the DRBC group. [Conclusion] Based on PSM analysis, there was no significant difference in the efficacy and safety of DRBC transfusion compared with SRBC transfusion, which can provide evidence-based support for routine application.

Spleen-stomach damp-heat syndrome is currently the most prevalent TCM pattern in patients with chronic atrophic gastritis (CAG), with internal damp-heat accumulation regarded as a key factor contributing to its prolonged and refractory course. This syndrome represents a critical stage in the progressive pathogenesis of CAG, characterized by a deepening pathological evolution. Modern TCM practitioners generally agree that its core pathogenesis lies in "deficiency in root and excess in superficiality, with internal damp-heat retention", and emphasize a treatment strategy that combines eliminating pathogenic factors and reinforcing the body's healthy qi through dynamic syndrome differentiation. Chinese materia medica used in treating CAG with spleen-stomach damp-heat syndrome can effectively relieve clinical symptoms, improve the internal damp-heat environment, mitigate gastric mucosal atrophy and intestinal metaplasia, and delay the inflammation-to-cancer transformation. Its mechanisms may involve eradication of Helicobacter pylori, repair of gastric mucosal injury, regulation of immune inflammatory response and other aspects, which has the advantages of multi-channel and multi-target.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective: To examine the mediating effect of resilience on AIDS-related stress and patient-reported outcome among elderly cases with HIV/AIDS, so as to provide the basis for promoting mental health and improving health outcomes of this population. Methods: From June to July 2024, elderly cases with HIV/AIDS receiving treatment in the infectious diseases department of a tertiary-level hospital in Sichuan Province and undergoing follow-up management at 12 community health service centers in Wuhou District, Chengdu City, Sichuan Province, were selected as study participants using convenience sampling method. Data on demographic information, duration since confirmed diagnosis and the most recent CD4+T lymphocyte count were collected through questionnaire surveys. The Chinese versions of the HIV/AIDS Stress Scale, the Chinese versions of the 10-item Connor-Davidson Resilience Scale, and the Patient-Reported Outcome Scale for Elderly HIV/AIDS Patients were used to assess AIDS-related stress, resilience, and patient-reported outcome, respectively. Structural equation modeling was performed using Mplus 8.3 software to analyze the mediating effect of resilience on AIDS-related stress and patient-reported outcome. The Bootstrap method was employed to test the significance of the mediating effect. Results: A total of 424 elderly HIV/AIDS cases were included, with a mean age of (62.04±8.73) years. Among them, 315 (74.29%) were males and 109 (25.71%) were females. The median scores were 23.00 (interquartile range, 11.00) points for AIDS-related stress, 30.00 (interquartile range, 7.00) points for resilience, and 363.45 (interquartile range, 53.03) points for the total score of patient-reported outcome. Resultsof the mediation effect analysis revealed that AIDS-related stress had a direct negative effect on patient-reported outcome (β=-0.608, 95%CI: -0.742 to -0.465). It also exerted an indirect negative effect on patient-reported outcome through the mediating role of resilience (β=-0.258, 95%CI: -0.364 to -0.158), with the mediating effect accounting for 29.79% of the total effect. Conclusion AIDS-related stress among elderly cases with HIV/AIDS can directly or indirectly negatively affect patient-reported outcome through resilience.

Objective To evaluate the efficacy of human papillomavirus E6/E7(HPV E6/E7)mRNA combined with colposcopy in screening cervical cancer and precancerous lesions.Methods A total of 480 patients with suspected cervical precancerous lesions in the hospital from July 2022 to De-cember 2024 were retrospectively selected as research objects.All the patients underwent HPV E6/E7 mRNA testing,colposcopy,and pathological examination.Taking the pathological examination results as the diagnostic golden standard,the diagnostic values of HPV E6/E7 mRNA and colposcopy alone as well as their combination were analyzed.Results The pathological examination results of 480 pa-tients showed that there were 192 negative cases,including 1 case of normal cervix and 191 cases of benign lesions;there were 288 positive cases,including 133 cases of low-grade squamous intraepithe-lial lesions(LSIL),110 cases of high-grade squamousintraepithelial lesions(HSIL),and 45 cases of cervical squamous cell carcinoma(SCC).The colposcopy results showed 211 true-positive cases and 138 true-negative cases;the HPV E6/E7 mRNA test results showed 199 true-positive cases and 137 true-negative cases;the combined test results showed 239 true-positive cases and 174 true-negative cases.The sensitivity(95.22％),specificity(75.98％),accuracy(86.04％),positive predic-tive value(81.29％),and negative predictive value(93.55％)of the combined test were signifi-cantly higher than those of each individual test(P＜0.001).Moreover,the consistency between the combined test and pathological results(Kappa=0.718,P＜0.001)was also significantly high-er than that of each individual test.Conclusion Compared with HPV E6/E7 mRNA or colposcopy alone,the combined test has higher clinical application value in screening of cervical precancerous lesions and cervical cancer,shows stronger consistency with pathological results,and is of great sig-nificance for the early differential diagnosis of cervical precancerous lesions and cervical cancer.

Objective: To investigate the role of transcription factor EB (TFEB) -autophagy pathway in rifampicininduced liver injury and its possible mechanism. Methods: Forty 6-8-week-old C57/BL6 mice were randomly divided into five groups : control group , model group , TFEB low-dose agonist group , TFEB high-dose agonist group , and autophagy agonist group , with 8 mice in each group. Except for the control group , the other four groups were given rifampicin 200 mg/(kg ·d) by gavage daily. TFEB agonist was administered intraperitoneally at a low dose of 20 mg/kg and a high dose of 50 mg/kg for 7 days at 1 h after rifampicin administration. Autophagy agonist was administered by gavage at a dose of 10 mg/kg 6 h before rifampicin administration on day 1 . The experiment was completed 7 days after modeling. The degree of liver injury was evaluated by detecting liver function indexes and liver pathological changes. Western blot was used to detect the protein expression total TFEB , chelator 1( p62) , microtubule-associated protein light chain 3(LC3) , benzyl chloride 1(Beclin-1) , sodium taurocholate co-transporting polypeptide(NTCP) and bile salt export pump(BSEP) levels in liver nucleus/liver tissue were quantified. Results: Compared with the control group , the serum levels of alanine aminotransferase ( ALT) , aspartate aminotransferase (AST) , total bilirubin ( TBIL) , direct bilirubin ( DBIL) , and total bile acid ( TBA) in the model group increased (P < 0. 05) , and obvious pathological changes were observed in the liver. Compared with the model group , the high dose and low dose of TFEB agonist and autophagy agonist groups had reductions in the above indicators (P < 0. 05) . Compared with the low-dose TFEB agonist group , the high-dose TFEB agonist group had reductions in the above indicators (P < 0. 05) . The proportion of TFEB in the nucleus was ( 1. 0 ± 0. 10) in the control group , (0. 6 ± 0. 05) in the model group , (0. 8 ± 0. 08) in the low-dose agonist group , and (0. 9 ± 0. 07) in the high-dose agonist group (P < 0. 05) . Autophagy agonist group (0. 7 ± 0. 06) (P < 0. 05) . Compared with the control group , the levels of NTCP and BSEP in the liver of the model group decreased (P < 0. 05) , and the expression of NTCP and BSEP in the TFEB low-dose and high-dose agonist groups were restored , and the expression of NTCP and BSEP in the autophagy agonist group also increased (P < 0. 05) . Compared with the control group , the protein expression levels of TFEB , LC3- Ⅱ/LC3- Ⅰand Beclin-1 in the liver tissue of the model group significantly decreased (P < 0. 05) , while the protein expression level of p62 significantly increased ( P < 0. 05) . Compared with the model group , the protein expression levels of TFEB , LC3- Ⅱ/LC3- Ⅰand Beclin-1 in the liver tissue of the TFEB agonist high-dose group , low-dose group and autophagy agonist group increased (P < 0. 05) , while the protein expression level of p62 decreased (P < 0. 05) . Conclusion TFEB can improve rifampicin-induced liver injury by activating autophagy pathway , and the main mechanism may be related to the up-regulation of NTCP and BSEP expression.

Objective:To investigate clinical efficacy and safety of dupilumab in the treatment of moderate to severe atopic dermatitis (AD) complicated with asthma.Methods:A self-controlled study before and after treatment was conducted to retrospectively analyze 45 patients with moderate to severe atopic dermatitis combined with asthma who received dupilumab in the respiratory allergy clinic of North Theater Command General Hospital from January 2021 to May 2024, which age ≥12 years, including 27 males, 18 females. The treatment period was 4 to 12 months. All patients were treated with dupilumab combined with inhaled glucocorticoids and long-acting beta2-receptor agonists, as well as symptomatic drugs for atopic dermatitis. Analyze the clinical data of the patients before and after treatment, including lung function, asthma and AD-related assessment scales. Generalized estimation equation was used to analyze the simple effect of time on the repeated measurement data following non-normal distribution, and Wilcoxon signed rank test was used to compare the differences of each observation index before and after treatment.Results:Among 45 patients with moderate to severe atopic dermatitis complicated with asthma, after treatment with dupilumab, the FEV 1 increased from 2.39 (1.87, 2.83) L at baseline to 2.50 (1.84, 2.97) L 3 months after treatment ( Z=2.417, P=0.016), 2.60 (1.95, 3.14) L 6 months after treatment ( Z=2.896, P=0.004); the FEV 1pred% increased from 74.10% (67.70%, 78.75%) at baseline to 77.09% (68.40%, 80.24%) at 3 months after treatment ( Z=2.574, P=0.010), and 77.20% (71.10%, 80.72%) at 6 months after treatment ( Z=2.861, P=0.004). Meanwhile, there were statistically significant differences in the ACT and Mini-AQLQ scales at 3, 6, and 12 months after treatment compared with those before treatment (ACT score Z=3.170, 4.216, 5.723; Mini-AQLQ score Z=3.231, 4.133, 5.826; all P<0.05). The EASI scale decreased from baseline 25.90 (18.95, 33.45) to 6.20 (1.15, 8.35) at 4 months after treatment ( Z=5.842, P<0.05) and 4.90 (2.75, 8.35) at 6 months after treatment ( Z=5.841, P<0.05), 4.00 (3.15, 5.05) at 12 months after treatment ( Z=5.841, P<0.05); The scores of each scale of IGA, NRS and DLQI decreased significantly compared with the baseline after 4 months, 6 months and 12 months of treatment, and this trend became more obvious with the extension of treatment time. The differences were statistically significant (IGA score Z=6.247, 6.070, 5.946; NRS score Z=5.960, 5.893, 5.879; DLQI score Z=5.880, 5.850, 5.848; all P<0.05). During treatment, 1 patient had local adverse reactions at the injection site and 1 patient had conjunctivitis. Conclusion:Dupilumab may have a positive effect on improving the clinical efficacy of patients with moderate to severe atopic dermatitis complicated with asthma. During the 12-month observation period, this biological agent generally demonstrated good safety characteristics.
