Objective: To investigate the association between dietary quality and overweight / obesity among primary school students, so as to provide a basis for the prevention and control of childhood obesity. Methods: In September 2022, third-grade students from six primary schools in Ningbo City, Zhejiang Province were selected by a random cluster sampling method. Data on gender, age, height, and weight were collected through questionnaire surveys and physical examinations. Body mass index (BMI) was calculated, and overweight and obesity were determined using gender- and age-specific BMI cut-off points. The Chinese dietary quality questionnaires was administered to assess the intake of health-promoting and restricted foods over the past 24 hours, thereby evaluating overall dietary quality. A multivariate logistic regression model was used to analyze the association between dietary quality and overweight / obesity among primary school students. Results: A total of 1 375 primary school students were included, comprising 722 (52.51%) boys and 653 (47.49%) girls, with a mean age of (8.47±0.30) years. Among them, 165 (12.00%) were overweight and 171 (12.44%) were obese. The score for health-promoting foods was (4.29±2.27) points. The median score of restricted foods was 2.00 (interquartile range, 3.00) points. The total dietary quality score was (10.84±2.42) points. Multivariable logistic regression analysis indicated that the restricted food score was positively associated with overweight (OR=1.073, 95%CI: 1.002-1.148), while the total dietary quality score was negatively associated with overweight (OR=0.911, 95%CI: 0.851-0.976). However, no statistically significant associations were observed between the health-promoting food score and overweight or obesity (both P>0.05), nor between the restricted food score or total dietary quality score and obesity (both P>0.05). Conclusion A higher intake of restricted foods was associated with an increased risk of overweight, while a better dietary quality was associated with a decreased risk of overweight among primary school students.

Objective To explore the key active ingredients and action characteristics of Wenxing Jingjintong Gel Patch in the treatment of rheumatoid arthritis(RA)based on the systematic pharmacology and LC-MS/MS technology.Methods The information of active ingredient from Wenxing Jingjintong Gel Patch was established through LC-MS/MS analysis and literature retrieval.The targets of the active ingredients were predicted using Swiss Target Prediction platform and then mapped with the RA-related targets obtained from GeneCards,DrugBank,and OMIM databases to identify the intersecting targets.The"active ingredients-effective targets"network was constructed through the Cytoscape software.The shared targets were imported into STRING database to construct a protein-protein interaction network.GO function and KEGG pathway enrichment analysis were performed using the Metascape database.Molecular docking studies were conducted using AutoDock software to investigate the interactions between key ingredients and target proteins.Results A total of 142 active ingredients were identified in Wenxing Jingjintong Gel Patch by wsing LC-MS/MS,which were further supplemented to 174 through literature retrieval.There were 175 shared targets between the active ingredients and RA.It was anticipated that Wenxing Jingjintong Gel Patch exerted immune regulation and anti-inflammatory and analgesic effects through the interaction between key active ingredients such as berberine,neobavaisoflavone,and palmatine chloride with key targets,including TNF,IL6,and AKT1 to regulate PI3K/Akt1,JAK/STAT,and MAPK signaling pathways.In 1 152 molecular docking validation,94%of them had binding energies less than-5.0 kcal·mol-1,while 51%of them had binding energies less than-7.0 kcal·mol-1.It was indicated that there was a good binding affinity between the potential active ingredients and core targets.Conclusion This study predicted the active ingredients and action characteristics of Wenxing Jingjintong Gel Patch in the treatment of RA,which provided a theoretical basis for further clinical application and quality control.

Objective:To investigate the effects of preoperative administration of parecoxib sodium on stress reaction and postoperative nausea and vomiting score in patients undergoing laparoscopic cholecystectomy.Methods:A total of 112 patients undergoing laparoscopic cholecystectomy in Lishui City People's Hospital from January 2020 to January 2021 were included in this study. They were randomly divided into observation group and control group, with 56 patients per group. The observation group was intravenously administered 40 mg parecoxib sodium 30 minutes before surgery, and the control group was identically administered equal amount of 0.9% sodium chloride injection. At 1, 6, 12 and 24 hours after surgery, Visual Analogue Scale (VAS) score, cortisol and adrenocorticotropic hormone levels and postoperative nausea and vomiting score were compared between the two groups.Results:At 1, 6 and 12 hours after surgery, VAS score in the observation group was (3.23 ± 0.85) points, (2.44 ± 0.76) points, (2.37 ± 0.69) points, respectively, which were significantly lower than (4.06 ± 1.12) points, (3.24 ± 0.95) points, (3.10 ± 1.07) points in the control group ( t = 4.41, 4.92, 4.29, all P < 0.001). At 1, 6, 12 and 24 hours after surgery, cortisol level in the observation group was (287.79 ± 35.46) ng/L, (303.55 ± 34.77) ng/L, (368.58 ± 31.22) ng/L, (397.16 ± 32.60) ng/L, respectively, which were significantly lower than (337.64 ± 39.52) ng/L, (364.18 ± 36.90) ng/L, (405.56 ± 37.29) ng/L, (455.51 ± 37.81) ng/L in the control group ( t = 7.02, 8.94, 5.69, 8.74, all P < 0.05). At 1, 6, 12 and 24 hours after surgery, adrenocorticotropic hormone level in the observation group was (59.25 ± 7.63) ng/L, (65.27 ± 8.23) ng/L, (72.29 ± 7.49) ng/L, (83.63 ± 8.57) ng/L, which were significantly lower than (64.48 ± 8.06) ng/L, (71.44 ± 8.59) ng/L, (79.79 ± 8.15) ng/L, (90.08 ± 8.26) ng/L in the control group ( t = 3.52, 3.88, 5.07, 4.05, all P < 0.05). Within 24 hours after surgery, the incidence of postoperative nausea and vomiting in the observation group was significantly lower than that in the control group [12.50% (7/56) vs. 28.57% (16/56), χ2 = 4.43, P < 0.05). Within 2 hours, 2-6 hours, and > 6-24 hours, postoperative nausea and vomiting score in the observation group was (1.31 ± 0.26) points, (1.43 ± 0.32) points, and (1.46 ± 0.41) points, respectively, which was significantly lower than (1.67 ± 0.41) points, (1.83 ± 0.39) points, (1.88 ± 0.44) points in the control group ( t = 2.12, 2.37, 2.14, all P < 0.05). Conclusion:Preoperative administration of parecoxib sodium exhibits a good postoperative analgesic effect in patients undergoing laparoscopic cholecystectomy. It can effectively reduce postoperative stress reactions, decrease the incidence of postoperative nausea and vomiting, and lower the severity of postoperative nausea and vomiting, and thereby can be widely used in clinical practice.

Background and objectives:Hepatic steatosis and inflammation are key characteristics of non-alcoholic fatty liver disease(NAFLD).However,whether and how hepatic steatosis and liver inflammation are differentially regulated remains to be elucidated.Considering that disruption of 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3(Pfkfb3/iPfk2)dissociates fat deposition and inflammation,the present study examined a role for Pfkfb3/iPfk2 in hematopoietic cells in regulating hepatic steatosis and inflammation in mice. Methods:Pfkfb3-disrupted(Pfkfb3+-)mice and wild-type(WT)littermates were fed a high-fat diet(HFD)and examined for NAFLD phenotype.Also,bone marrow cells isolated from Pfkfb3+/-mice and WT mice were differentiated into macrophages for analysis of macrophage activation status and for bone marrow transplantation(BMT)to generate chimeric(WT/BMT-Pfkfb3+/-)mice in which Pfkfb3 was disrupted only in hematopoietic cells and control chimeric(WT/BMT-WT)mice.The latter were also fed an HFD and examined for NAFLD phenotype.In vitro,hepatocytes were co-cultured with bone marrow-derived macrophages and examined for hepatocyte fat deposition and proinflammatory responses.Results:After the feeding period,HFD-fed Pfkfb3+/-mice displayed increased severity of liver inflam-mation in the absence of hepatic steatosis compared with HFD-fed WT mice.When inflammatory activation was analyzed,Pfkfb3+/-macrophages revealed increased proinflammatory activation and decreased anti-proinflammatory activation.When NAFLD phenotype was analyzed in the chimeric mice,WT/BMT-Pfkfb3+/-mice displayed increases in the severity of HFD-induced hepatic steatosis and inflammation compared with WT/BMT-WT mice.At the cellular level,hepatocytes co-cultured with Pfkfb3+/-macrophages revealed increased fat deposition and proinflammatory responses compared with hepatocytes co-cultured with WT macrophages. Conclusions:Pfkfb3 disruption only in hematopoietic cells exacerbates HFD-induced hepatic steatosis and inflammation whereas the Pfkfb3/iPfk2 in nonhematopoietic cells appeared to be needed for HFD feeding to induce hepatic steatosis.As such,the Pfkfb3/iPfk2 plays a unique role in regulating NAFLD pathophysiology.

3T3-L1 adipocytes were cultured with various concentrations of high-density lipoprotein ( HDL, 0, 10, 50, and 100 μg/ml ) for 16 h and with lipopolysaccharide ( LPS, 100 ng/ml ) for another 6 h. Interleukin-8 in the medium was determined by ELISA, and PPAR-γ mRNA expression by reverse transacription polymerase chain reaction (RT-PCR). Interleukin-8 levels were increased in LPS-treated cells ( P＜0.05 ), but decreased in HDL-treated cells in the dose-dependent manner. PPARγ mRNA expressions were increased in HDL-treated groups than those treated only with LPS. These results suggested HDL may decrease interleukin-8 secretion via up-regulating PPARγ expression in adipocytes.
