Objective: To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures. Methods: From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children. Results: The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05). Conclusion Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

As a potential vectored vaccine,Newcastle disease virus(NDV)has been subject to various studies for vaccine development,while relatively little research has outlined the immunomodulatory effect of the virus in antigen presentation.To elucidate the key inhibitory factor in regulating the interaction of infected dendritic cells(DCs)and T cells,DCs were pretreated with the NDV vaccine strain LaSota as an inhibitor and stimulated with lipopolysaccharide(LPS)for further detection by enzyme-linked immunosorbent assay(ELISA),flow cytometry,immunoblotting,and quantitative real-time polymerase chain reaction(qRT-PCR).The results revealed that NDV infection resulted in the inhibition of interleukin(IL)-12p40 in DCs through a p38 mitogen-activated protein kinase(MAPK)-dependent manner,thus inhibiting the synthesis of IL-12p70,leading to the reduction in T cell proliferation and the secretion of interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α),and IL-6 induced by DCs.Consequently,downregulated cytokines accelerated the infection and viral transmission from DCs to T cells.Furthermore,several other strains of NDV also exhibited inhibitory activity.The current study reveals that NDV can modulate the intensity of the innate?adaptive immune cell crosstalk critically toward viral invasion improvement,highlighting a novel mechanism of virus-induced immunosuppression and providing new perspectives on the improvement of NDV-vectored vaccine.

Objective To explore the factors influencing the occurrence of cardiac complications after endoscopic surgery in patients with non-small cell lung cancer(NSCLC)and construct the prediction model.Methods A total of 312 patients with non-small cell lung cancer who were diagnosed and underwent thoracoscopic treatment in our hospital from January 2020 to January 2023 were selected as the objects of this study,and were divided into cardiac complication group and non-cardiac complication group according to whether cardiac complications occurred after surgery.The clinical data of patients in each group were analyzed,and the factors affecting the occurrence of cardiac complications in patients with non-small cell lung cancer after endoscopic surgery were discussed by multivariate Logistic regression analysis.A full-variable risk prediction model for the occurrence of cardiac complications was constructed,and the predictive model was verified by receiver operating characteristic curve(ROC)analysis.Results The incidence of postoperative cardiac complications in 312 patients with non-small cell lung cancer was 24.04％.Univariate analysis showed that Age,smoking history,smoking history,comorbidities,intraoperative blood loss,operative time,systolic blood pressure,FEV1,FEV1％,FPG,HbA1c and urinary microalbumin were correlated with the incidence of cardiac complications in patients with non-small cell lung cancer after endoscopic surgery(P＜0.05).Multivariate Logistic stepwise regression analysis showed:age,comorbidities,operation time and HbA1c were independent risk factors for postoperative cardiac complications in patients with non-small cell lung cancer(P＜0.05).A risk prediction model for cardiac complications was established based on multiple factors,that is,P=1/(1+e-y),y=-3.114+0.881 × age+0.754 × complications+1.285 × operation time+1.185 × HbA1c,and the ROC curve diagnosis showed that the risk prediction model predicted the occurrence of cardiac complications with an AUC of 0.847,95％CI of 0.769-0.925,sensitivity of 82.5％,specificity of 83.2％.Conclusion Age,complications,operation time,and HbA1c are all independent risk factors affecting the occurrence of cardiac complications in patients with non-small cell lung cancer after endoscopic surgery,and the risk prediction model constructed by the above factors has a good predictive value for the occurrence of cardiac complications.

Objective:To evaluate the efficacy and safety of first-line anti-tuberculosis (TB) drugs combined with linezolid in treatment of children with tuberculous meningitis (TBM).Methods:A retrospective cohort study design was performed . Eight-nine Children diagnosed as TBM during January 1 st 2016 and December 31 st 2023 in Department of Infectious Disease, Children′s Hospital of Chongqing Medical University were enrolled in the study. According to different treatment regimens, children were divided into a group of first-line anti-tuberculous drugs (isoniazid, rifampicin, pyrazinamide, ethambutol (HRZE)) and a group of HRZE and linezolid combination (HRZEL). The efficacy and safety of the 2 regimens were compared and the relationship between linezolid drug concentration and adverse reactions were analyzed. Comparisons between groups were performed using χ2 test and Mann-Whitney U test. Results:The 89 children with TBM included 53 males and 36 females with an onset age of 4.6 (1.4, 9.6) years. There were 27 cases in the HZREL group and 62 cases in the HRZE group. Before treatment, positive rate of interferon-gamma release assays (IGRA) in HRZEL group was lower than that in HRZE group (64% (16/25) vs.92% (55/60), χ2=9.82, P<0.05), but protein level of cerebrospinal fluid (CSF) was higher than that in HRZE group (1.2 (1.0, 2.0) vs.0.8 (0.4,1.4) g/L, Z=0.32, P<0.05). By the end of the intensive phase, there were no significant differences of rates of CSF improvement and etiology negativity between HRZEL group and HRZE group (both P>0.05).The 44 TBM children with high CSF protein (>1 g/L) included 25 males and 19 females with an onset age of 6.7 (3.0, 11.8) years. There were 21 cases in the HZREL group and 23 cases in the HRZE group accordingly. Before treatment, there were no significant differences of positive rate of IGRA test and CSF protein level between the 2 groups (62% (13/21) vs. 87% (20/23), 1.7 (1.1, 2.2) vs. 1.5 (1.2, 1.9) g/L, χ2=3.67, Z=0.23, both P>0.05). There were no significant differences in CSF indicators, etiology negativity or imaging remission between the two groups by the end of intensive phase (all P>0.05). Higher frequencies of granulocytopenia, gastrointestinal symptoms as well as withdrawal or change of drugs were found in HRZEL group when compared to those in HRZE group (44% (12/27) vs. 19% (12/62), 7% (2/27) vs. 0, 33% (9/27) vs. 3% (2/62), χ2=6.01, 4.70, 15.74, all P<0.05). Conclusions:The efficacy of HRZEL regimen is similar to conventional HRZE regimen in children with TBM, but with higher adverse effect. Prudentially evaluating the pros and cons of linezolid in the usage of drug-susceptible TB and carefully monitoring of linezolid associated adverse effects is suggested.

Objective:To evaluate the efficacy and safety of standardized dust mite allergen subcutaneous immunotherapy (SCIT) in children with allergic rhinitis (AR) during treatment.Methods:A total of 283 children with AR diagnosed with definite dust mite allergy and completed 2 to 3 years of SCIT who attended the Department of Otorhinolaryngology Head and Neck Surgery, Xiangya Hospital, Central South University, from August 2019 to October 2021 were included, including 205 males and 78 females, with a mean age of 10.8 years. The total nasal symptoms score (TNSS), symptom medication score (SMS), rhinoconjunctivitis quality of life questionnaire (RQLQ) and visual analogue scale (VAS) before and after 2 to 3 years′ treatment were recorded, and the differences before and after treatment were compared. Adverse reactions during SCIT were recorded to evaluate its safety. SPSS 22.0 software was used for statistical analysis.Results:The overall effectiveness rate during SCIT in 283 children with AR was 89.4% (253/283). Compared with baseline, all symptom scores, medication scores and quality of life scores were significantly lower after 2 to 3 years of SCIT (all P<0.05). Further group comparisons showed positive efficacy in patients with different clinical characteristics, including age, gender, smoking status, family history of AR, symptom severity, mono-or poly-allergy, and second immunization, with no statistically significant differences between groups (all P>0.05). A total of 12 735 injections were administered during the SCIT, and a total of 213 (1.67%) injections of local adverse reactions occurred, mainly in the initial treatment phase, and the diameter of the local air mass was mostly 5 to 20 mm; 71 (0.56%) injections of systemic adverse reactions occurred, mainly in the initial treatment phase, and most of them were grade 1 reactions with no serious systemic adverse reaction such as shock. Conclusion:Standardized dust mite SCIT has a good safety profile and definite efficacy in treating AR children with different clinical characteristics. It can significantly improve all symptoms, reduce the use of symptomatic drugs and improve their quality of life.

Objective:To investigate the effect of total saponins of Panax notoginseng (TSPN) on learning and memory of post-stroke depression (PSD) rats and its mechanism.Methods:Four-vessel occlusion method was used to build the rat stroke model and 7 days later these rats were given solitary breeding with chronic unpredictable mild stress (CUMS) to make depression model. Rats were randomly divided into Sham group ( n=10), Model group ( n=10), PSD group ( n=10) and TSPN group ( n=10). The rats in the Model group and PSD group were injected administered with equal volume of 0.9% saline 30 min post-brain ischemia, one injection per day for 30 days. while TSPN group were treated with TSPN. The dose of TSPN (75 mg/kg) was dissolved in 0.9% saline 10 g/L, once per day for 30 days. Then the learning and memory of rats were tested by Morris water maze.The protein levels of DCX and Nestin in the hippocampus were detected by Western blot. Furthermore, the DCX/Ki67 co-labeled cells in the SGZ of hippocampus were observed by the immunofluorescence. Results:The escape latency at the fifth day of PSD group((31.8±3.8)s) was longer than that in the Sham group((10.4±3.2)s) and Model group((19.8±3.7)s) ( t=9.23, 5.15; both P<0.05). The escape latency ((14.2±2.8)s) of TSPN group was shortened significantly than PSD group ( t=8.56, P<0.05). The times across the platform in the Sham group was (10.3±1.7), and the PSD group was (4.1±1.1), difference was statistically significant between two groups( t=11.24, P<0.05). The times across the platform (8.4±1.6) of TSPN group statistically increased compared with PSD group ( t=5.77, P<0.05). The protein levels of DCX and Nestin in the PSD group were (0.60±0.02), (0.58±0.03) respectively, and in the TSPN group were (1.07±0.07), (0.95±0.11) correspondingly, there were significant differences of the DCX, Nestin protein level between the two groups( t=20.22, 7.68, both P<0.01). Moreover, there was significant difference in the number of the DCX/Ki67cells in the hippocampus SGZ between the PSD group((16.2±2.8) /mm 2) and TSPN group ((21.2±3.1) /mm 2)( t=2.42, P<0.05). Conclusion:TSPN could improve the learning and memory of the rats with post-stroke depression through enhancing the hippocampus neurogenesis.

OBJECTIVE： To establish the method for simultaneous determination of clopidogrel （CLP）， its intermediate metabolite （2-O-CLP）， inactive metabolite （CLPCA） and active metabolite （CLPTM） in human plasma. METHODS： Totally 90 patients diagnosed as stroke were selected from the First Affiliated Hospital of Army Medical University. They were given one CLP tablet （75 mg/tablet） orally on an empty stomach in the morning. Blood samples were collected 2 h after taking the tablet. CLPTM- D was formed by derivation of CLPTM with 2-bromo-3’-methoxyacetophenone and extracted by precipitation of acetonitrile protein together with the other three substances to be measured. LC-MS/MS method was adopted. The determination was performed on Agilent poroshell 120 EC-C18 column with mobile phase consisted of acetonitrile （0.1％ formic acid） and water （0.1％ formic acid） （90 ∶ 10， V/V）. The quantitation analysis was performed using multiple reaction monitoring at the specific ion transitions of m/z 308.1→198.1 （CLPCA）， 322.3→212.0 （CLP）， 338.3→155.0 （2-O-CLP）， 504.4→354.1 （CLPTM-D） and 264.0→154.1 （ticlopidine， internal standard）， respectively. RESULTS： The retention time of CLPCA， CLP， 2-O-CLP， CLPTM-D and internal standard were 2.01， 3.32， 2.83， 2.68， 1.87 min， respectively. The linear range of CLPCA， CLP， 2-O-CLP and CLPTM-D were 100-10 000， 0.2-20， 0.3-30， 0.5-50 ng/mL （all r≥0.999 5）. The intra-day and inter-day RSD were all less than 9.5％ （n＝5）. Accuracy ranged from 93.5％-98.9％ （n＝5）， and extraction recovery was from 85.4％ to 95.9％ （n＝5）. The matrix effect ranged from 2.7％-6.2％ （n＝5）. In stability tests （storing at －80 ℃ for 3 months， 3 freeze-thaw cycles， storing at 4 ℃ for 8 h）， RE of CLP， CLPCA and CLPTM-D were all lower than 10.0％ （n＝5）. CONCLUSIONS： Established LC-MS/MS method has the advantages of high specificity， accuracy and reliability， and can be used to detect the concentration of CLP and its three metabolites in human plasma.
