Objective: To explore the current status and influencing factors of eating behaviors in adolescents, so as to provide a theoretical foundation for health promotion education among adolescents. Methods: Based on the database from Survey of Chinese Family Health Index (2021), by a random number table method, 1 065 teenagers were selected from the provincial capitals of 22 provinces and 5 autonomous regions in China, as well as 4 municipalities directly under the central government. A general characteristic questionnaire, Patient Health Questionnaire-9 (PHQ-9), Short Form of the Family Health Scale (FHS-SF), 10-item Short Version of the Big Five Personality(BFP-10), Content-based Media Exposure Scale (CM-E) and Sakata Eating Behavior Scale Short Form(EBS-SF) were used to collect information. Multivariate stepwise linear regression analysis was employed to identify and analyze related factors of eating behaviors among adolescents. Receiver operating characteristic was used to validate the predictive ability of the EBS-SF score for overweight and obesity among adolescents. Results: The average scores of BFI-10,C-ME, FHS-SF, PHQ-9 and EBS-SF were (33.08±4.64)(19.20±4.55)(38.48±6.65)(6.09±5.63)(16.75±4.36), respectively. Multivariate linear regression showed that family type (other types), agreeableness, conscientiousness, family health and depression were the main related factors of EBS-SF scores among adolescents( B =2.61,-0.42,0.20,-0.11,0.23, P <0.05).The analysis of receiver operating characteristic curve showed that the EBS-SF scores had a good ability in predicting obesity among male adolescents ( AUC= 0.73, P <0.01). Conclusions Family type, big five personality, family health,depression are the related factors of eating behaviors among adolescents. EBS-SF scores are predictive of obesity in adolescents, which would provide a new perspective for promoting healthy eating habits among adolescents.

OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland （HMG）. METHODS Female SD rats were divided into control group and HMG group according to body weight， with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling， two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid （calculated by crude drug） intragastrically， once a day， for 7 consecutive days. Blood samples were collected before the first administration （0 h）， and at 5， 15， 30 minutes and 1， 2， 4， 8， 12， 24 hours after the last administration， respectively. Using chlorzoxazone as the internal standard， the plasma concentrations of ferulic acid， paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve （AUC0－24 h， AUC0－∞）， mean residence time （MRT0－∞）， half-life （t1/2）， peak time （tmax）， peak concentration （cmax）] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software.

Methods: Forty-eight SPF healthy male ICR mice were randomly divided into control group and low (0.5 g/kg), medium (2.0 g/kg), and high (4.0 g/kg) dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day. The delayed allergy test was performed for 28 consecutive days. Sixty SPF healthy male ICR mice were randomly divided into a control group, polyinosinic acid injection group (model group), and low, medium, and high dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day for 14 consecutive days. On days 13 and 14 of administration, the mice in the model group and each dose group were intraperitoneally injected with sterile polyinosinic acid solution to perform the immunosuppressive experiment induced by polyinosinic acid. The mouse ear pieces were weighed, and the thymus and spleen of the mice were weighed and stained with HE to calculate the pathological scores. Peripheral blood was collected for blood cell detection and T cell classification. Results: Mice in each group had normal feeding, activity, and growth status, and no abnormality was observed. In the delayed allergy test, compared with the control group, the degree and rate of ear swelling in the low, medium and high dose groups were higher, the white blood cell count in the medium dose group was higher, and the absolute values of lymphocytes in the low and medium dose groups were higher (all P<0.05). Compared with the control group, the pathological scores of the thymus and spleen in the model group were higher (both P<0.05). In the immunosuppressive experiments in mice induced by polyinosinic acid, compared with the model group, the pathological score of the thymus in the high dose group was lower (P<0.05), and the boundary between the thymus cortex and medulla was improved. Conclusions Atractylodes macrocephala Koidz. extract can increase the degree of ear swelling and peripheral blood white blood cell count in mice. High dose of Atractylodes macrocephala Koidz. extract can improve the thymus injury induced by polyinosinic acid, and has an immunomodulatory effect.

Objective: To investigate the subclinical eating disorders among college students and to analyze associated factors, so as to provide a basis for the prevention and treatment of eating disorders among adolescents. Methods: From November to December 2023, a total of 5 201 college students were selected by stratified random cluster sampling from one undergraduate college and one specialized college in Yangzhou City, Jiangsu Province. Data on general information, subclinical eating disorders, body image perception, depressive symptoms, anxiety symptoms, and mental health literacy were collected using questionnaires. The Chisquare test was used to compare the detection rates of subclinical eating disorders between groups, and binary Logistic regression was employed to analyze associated factors. Results: The detection rate of subclinical eating disorders among college students was 16.0%. Binary Logistic regression analysis showed that the prevalence of subclinical eating disorders among college students was higher in the following categories:being in a relationship (OR=1.22, 95%CI=1.04-1.44), being overweight and obese (OR=2.75, 3.82, 95%CI=2.24-3.38, 2.89-5.06), overestimation of body shape (OR=2.04, 95%CI=1.68-2.49), being in a depressive state (OR=2.53, 95%CI=1.99-3.21), experiencing anxiety (OR=2.63, 95%CI=2.16-3.20), and having substandard mental health literacy (OR=1.37, 95%CI=1.11-1.70). Conversely, low body weight (OR=0.15, 95%CI=0.10-0.22) and underestimation of body shape (OR=0.37, 95%CI=0.27-0.51) were associated with a lower risk (P<0.05). Conclusions The detection rate of subclinical eating disorders among college students is high, and it is associated with relationship status, body mass index classification, body shape perception, depressive and anxiety symptoms, and mental health literacy. Comprehensive interventions should be implemented to improve the subclinical eating disorders and promote the physical and mental health of college students.

OBJECTIVE To explore the effects of ursolic acid （UA） on the growth， invasion， apoptosis and metastasis of human colorectal cancer cells SW620 and find out the underlying molecular mechanisms. METHODS The effects of different concentrations （0， 5， 10， 15， 20， 25， 30 μmol/L） of UA on the proliferation of SW620 cells for different durations （24， 48， 72 h） were detected by CCK-8 assay； the clone formation was detected by clone formation assay after SW620 cells were treated with different concentrations of UA （0，10，15，20 μmol/L） for 10 days. After SW620 cells were treated with different concentrations of UA （0， 10， 15， 20 μmol/L） for 24 hours， flow cytometry， Transwell invasion assay and Western blot assay were adopted to detect apoptosis and invasion of SW620 cells， and the expressions of B cell lymphoma 2 （Bcl-2）， cleaved-poly （ADP-ribose） polymerase （cleaved-PARP）， phosphorylated p38 mitogen-activated protein kinase （p-p38 MAPK）， p38 MAPK， E-cadherin， N-cadherin and zinc finger transcription factor Snail. The effects of p38 MAPK inhibitor （SB203580） combined with UA on the protein expressions of p-p38 MAPK， Bcl-2 and N-cadherin were investigated. RESULTS Compared with 0 μmol/L UA， the stone5999@163.com survival rates of SW620 cells treated with 5-30 μmol/L UA for 24， 48 and 72 h were significantly decreased （P＜0.05）. The clone formation rate of cells treated with 15 μmol/L and 20 μmol/L UA was significantly decreased （P＜0.05）. After being treated with 15 μmol/L and 20 μmol/L UA， the cell apoptosis rate， the protein expressions of cleaved-PARP and E-cadherin， and the phosphorylation of p38 MAPK protein were increased； but the number of transmembrane cells， and the protein expressions of Bcl-2， Snail and N-cadherin were decreased； there was statistical significance in difference of most indexes （P＜0.05）. Some indexes changed in a concentration-dependent manner （P＜0.05）. SB203580 could significantly inhibit the upregulation of p38 MAPK by UA and reverse the inhibitory effect of UA on the protein expressions of Bcl-2 and N-cadherin （P＜0.05）. CONCLUSIONS UA can inhibit the growth， invasion and metastasis of SW620 cells， and induce cell apoptosis， the mechanism of which may be attributed to the activation of p38 MAPK signaling pathway.

OBJECTIVE To provide reference for basic analysis of the pharmacodynamic substance in Stahlianthus involucratus. METHODS Overall 24 SD male rats were randomly divided into blank group （purified water）， and administration group （ethanol extract of S. involucratus， 15.75 g/kg， calculated by crude drug）， with 12 rats in each group. They were given drug liquid/purified water intragastrically， twice a day， every 6-8 h， for consecutive 3 days. After medication， the blood， urine and fecal samples were collected from two groups of rats. UPLC-Q-Exactive-MS technology was used to identify the chemical constituents in the ethanol extract of S. involucratus， and metabolites in the blood， urine and fecal of rats after intragastrical administration of the ethanol extract of S. involucratus. Multivariate statistical analysis was employed to screen various serum metabolites. Metabolic pathways were analyzed by MetaboAnalyst 5.0 platform. RESULTS A total of 38 chemical constituents were identified from the ethanol extract of S. involucratus， including fourteen prototype components and three metabolites identified from 5 urine samples， nine prototype components identified from fecal samples， and ten prototype components and one metabolite identified from serum samples. A total of 71 differential metabolites were screened from two groups of rat serum samples， of which 44 differential metabolites， such as ferulic acid， glycyrrhizin， were up-regulated and 27 differential metabolites， such as arachidonic acid， phenylacetylglutamine， were down-regulated. The 71 differential metabolites were mainly enriched in 11 metabolic pathways， including phenylalanine metabolism， linoleic acid metabolism， arachidonic acid metabolism， and tryptophan metabolism. CONCLUSIONS Ferulic acid， liquiritigenin， isofraxidin and formononetin may be the material basis that directly exert pharmacological effects of S. involucratus. S. involucratus may exert anti-inflammatory effects by affecting metabolic pathways， including arachidonic acid metabolism and tryptophan metabolism.

Objective: To investigate the effects and mechanisms of Xuebijing injection (XBJ) on Chimeric antigen receptor-T (CAR-T) cell function and its therapeutic potential against CAR-T therapy-associated cytokine storms (CRS). Methods: Anti-CD19 CAR-T cells were established based on FMC63 antibodies. Different doses of XBJ (1 and 10 mg/mL) were added to the culture system. Untreated anti-CD19 CAR-T cells served as negative controls. After 48-h co-culture, the effects of XBJ on CAR-T cell function were assessed. Carboxyfluorescein diacetate succinimidyl ester staining was used to assess the effect of XBJ on CAR-T cell proliferation. Flow cytometry, luciferase reporter gene assays, and real time cellular analysis were employed to evaluate the effects of XBJ on CAR-T cell cytotoxicity in vitro. RNA-sequencing was performed to analyze the effects of XBJ on CAR-T cell gene expression. Network pharmacology predicted potential XBJ therapeutic targets for CRS, which were verified in a THP-1 macrophage inflammation model. Results: XBJ enhanced both the proliferation and tumor killing capacities of CAR-T cells. Transcriptome analysis showed that XBJ treatment affects multiple genes and pathways in CAR-T cells, with differential gene enrichment in multiple cell proliferation and growth factor pathways. Potential targets for CRS control by XBJ were predicted using network pharmacology, and the inhibitory effect of XBJ on the expression of relevant genes was verified using a macrophage model. Conclusion The results of this study indicate that XBJ can enhance the killing effect of CAR-T cells on tumor cells and that the mechanism is related to the regulation of T cell proliferation and activation. Moreover, XBJ inhibited excessive inflammation associated with CAR-T therapy. However, the current findings remain to be further validated through in vivo experiments.

Objective To explore the efficacy and safety of antiplatelet therapy in patients with acute ischemic stroke(AIS)complicated with gastric cancer.Methods Clinical data of 89 patients with AIS complicated with gastric cancer who were hospitalized in the First People's Hospital of Huzhou from January 2018 to October 2022 were retrospectively analyzed.The patients were divided into treatment group(59 cases)and untreated group(30 cases)according to whether they received antiplatelet therapy or not,and the clinical characteristics and prognosis of the two groups were compared.To analyze the clinical features and influencing factors of gastrointestinal bleeding complicated by antiplatelet therapy in AIS patients with gastric cancer.Results The patients in treatment group were younger than those in untreated group,and had more history of antiplatelet therapy,hypertension and cardiovascular disease,the difference was statistically significant(P<0.05).The National Institute of Health stroke scale(NHISS)and modified Rankin scale(mRs)of patients in treatment group were lower than those in untreated group after antiplatelet therapy,the difference was statistically significant(P<0.05).The incidence of bleeding in treated group was significantly higher than that in untreated group(P<0.05),most of the patients had mild hemoglobin decline.Multivariate Logistic analysis suggested that chronic renal insufficiency,gastric cancer lesion diameter≥2cm and T1-T2 stage are risk factors for gastrointestinal bleeding in AIS patients with gastric cancer after taking aspirin for antiplatelet therapy.Conclusion In AIS patients with gastric cancer,aspirin antiplatelet therapy can effectively improve cerebrovascular function and reduce the degree of brain nerve damage.However,when these patients are combined with T1-T2 stage,chronic renal insufficiency and gastric cancer lesion diameter≥2cm,gastrointestinal bleeding is easy to occur.

Objective To investigate the effects of kuwanon G(KG)on proliferation,apoptosis,migration and invasion of gastric cancer cells and the molecular mechanisms.Methods The effects of KG on proliferation and growth of gastric cancer cells were assessed with CCK-8 assay and cell clone formation assay,by observing tumor formation on the back of nude mice and using immunohistochemical analysis of Ki-67.The effect of KG on cell apoptosis was analyzed using Annexin V-FITC/PI apoptosis detection kit,Western blotting and TUNEL staining.The effects of KG on cell migration and invasion were detected using Transwell migration and invasion assay and Western blotting for matrix metalloproteinase(MMP).The role of phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)/mammalian target of rapamycin(mTOR)pathway in KG-mediated regulation of gastric cancer cell proliferation,migration,and invasion was verified by Western blotting and rescue assay.Results KG significantly inhibited proliferation and reduced clone formation ability of gastric cancer cells in a concentration-dependent manner(P<0.05).KG treatment also increased apoptosis,enhanced the expressions of cleaved caspase-3 and Bax,down-regulated Bcl-2,lowered migration and invasion capacities and inhibited the expression of MMP2 and MMP9 in gastric cancer cells(P<0.05).Mechanistic validation showed that KG inhibited the activation of the PI3K/AKT/mTOR pathway,and IGF-1,an activator of the PI3K/AKT/mTOR pathway,reversed the effects of KG on proliferation,migration and invasion of gastric cancer cells(P<0.05).Conclusion KG inhibits proliferation,migration and invasion and promotes apoptosis of gastric cancer cells at least in part by inhibiting the activation of the PI3K/AKT/mTOR pathway.
