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 investigate the effect of early postoperative abnormal blood glucose on the short-term prognosis of non-small cell lung cancer(NSCLC),and to analyze the clinical characteristics and risk factors related to poor early prognosis.Methods A total of 897 patients with NSCLC who underwent thoracoscopic surgery in Huadong Hospital,Fudan University from Jan 2020 to Aug 2021 were divided into hyperglycemia(HG)group(>7.8 mmol/L)and normal blood glucose(NG)group(≤7.8 mmol/L and≥3.9 mmol/L)according to the early postoperative blood glucose values.Additionally,the patients were divided into higher blood glucose fluctuation group(≥4 mmol/L)and the group with lower blood glucose fluctuation(<4 mmol/L)basing on the fasting blood glucose.Using Logistic regression models,column line charts,ROC curves and other methods,we aimed to clarify the impact of early postoperative blood glucose abnormalities on short-term prognosis,explore clinical characteristics associated with poor short-term outcomes,identify other high-risk factors,and establish relevant risk prediction models.Results Compared with the NG group,the incidence of postoperative pneumonia,thromboembolism,ICU admission rate,total length of hospital stay and hospital cost were significantly higher in the HG group(P<0.05).Higher blood glucose fluctuation group had a greater risk of ICU admission(P=0.003).Logistic regression analysis showed that age,preoperative fasting glucose,white blood cell count and cytokeratin 19 fragment antigen 21-1(CYFRA21-1)were risk factors for postoperative hyperglycemia(P<0.05).Contrary to the effect of BMI,diabetes,male patients,higher blood glucose fluctuation,white blood cell count and age were the risk factors for postoperative adverse events(P<0.05).The AUC of the column line chart model was 0.661(95%CI:0.624-0.698),indicating good discriminative ability for predicting poor short-term prognosis postoperatively.Calibration curves also demonstrated good consistency between predicted and actual probabilities.Conclusion Early postoperative blood glucose fluctuations independently impact the short-term prognosis of thoracoscopic NSCLC patients.Blood glucose combined with gender,BMI,white blood cell count,age and diabetes history can serve as predictive factors for poor short-term prognosis postoperatively.Additionally,a column line chart constructed based on these factors may aid clinicians in early intervention for NSCLC patients with indications.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the effects of tumor burden score (TBS) and post-radiotherapy alpha-fetoprotein (AFP) stabilization time on the prognosis of hepatocellular carcinoma (HCC) patients complicated with portal vein tumor thrombus (PVTT).Methods:Clinical data of 40 eligible HCC patients complicated with PVTT admitted to the Affiliated Tumor Hospital of Xinjiang Medical University from July 2018 to March 2022 were retrospectively analyzed. The objective response rate (ORR), overall survival (OS), progression-free survival (PFS), AFP response, and post-radiotherapy AFP stabilization time in the entire group were observed. Diagnostic thresholds were determined by the receiver operating characteristic (ROC) curve. Survival analysis was conducted by Kaplan-Meier method, and the differences of survival rate were assessed by log-rank test. Multivariate analysis was performed by Cox proportional risk model.Results:The optimal cut-off value for TBS was 4.27 [area under the ROC curve (AUC)=0.752, P=0.018]. The ORR in the entire group was 35.7%, with a median OS and PFS of 8 and 5 months, respectively. The median AFP stabilization time was 6 months. Univariate analysis showed that a total of 9 factors were associated with OS, including gender, maximum tumor diameter, TBS, China liver cancer staging, aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio, gamma-glutamyl transferase (GGT), radiation dose, AFP stabilization time, and tumor response. Multivariate analysis showed that TBS>4.27 ( HR=0.195, 95% CI=0.060-0.638, P=0.007), China liver cancer stage Ⅲb staging ( HR=0.328, 95% CI=0.144-0.745, P=0.008), and AFP stabilization time ≤6 months ( HR=10.282, 95% CI=2.304-45.883, P=0.002) were the independent risk factors for OS in HCC patients complicated with PVTT. Conclusion:HCC patients complicated with PVTT who have low TBS and AFP stabilization time after radiotherapy may obtain longer OS, and the combination of TBS and AFP is expected to become a new risk assessment model.

This paper aimed to study the effect of Erjing Pills on the improvement of neuroinflammation of rats with Alzheimer's di-sease(AD) induced by the combination of D-galactose and Aβ_(25-35) and its mechanism. SD rats were randomly divided into a sham group, a model control group, a positive drug group(donepezil, 1 mg·kg~(-1)), an Erjing Pills high-dose group(9.0 g·kg~(-1)), and an Erjing Pills low-dose group(4.5 g·kg~(-1)), with 14 rats each group. To establish the rat model of AD, Erjing Pills were intragastrically administrated to rats for 5 weeks after 2 weeks of D-galactose injection. D-galactose was intraperitoneally injected into rats for 3 weeks, and then Aβ_(25-35) was injected into the bilateral hippocampus. The new object recognition test was used to evaluate the learning and memory ability of rats after 4 weeks of intragastric administration. Tissues were acquired 24 h after the last administration. The immunofluorescence method was used to detect the activation of microglia in the brain tissue of rats. The positive expressions of Aβ_(1-42) and phosphory protein Tau~(404)(p-Tau~(404)) in the CA1 area of the hippocampus were detected by immunohistochemistry. The levels of inflammatory factors interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), and interleukin-6(IL-6) in the brain tissue were determined by enzyme-linked immunosorbent assay(ELISA). Toll-like receptor 4(TLR4)/nuclear factor kappa B(NF-κB)/nucleotide-binding oligomerization domain-like receptors 3(NLRP3) pathway-associated proteins in the brain tissue were determined by Western blot. The results showed that as compared with the sham group, the new object recognition index of rats in the model control group decreased significantly, the deposition of Aβ_(1-42) and p-Tau~(404) positive protein in the hippocampus increased significantly, and the levels of microglia activation increased significantly in the dentate gyrus. The levels of IL-1β, TNF-α, and IL-6 in the hippocampus of the model control group increased significantly, and the expression levels of TLR4, p-NF-κB p65/NF-κB p65, p-IκBα/IκBα, and NLRP3 proteins in the hippocampus increased significantly. Compared with the model control group, the Erjing Pill groups enhanced the new object recognition index of rats, decreased the deposition of Aβ_(1-42) and the expression of p-Tau~(404) positive protein in the hippocampus, inhibited the activation of microglia in the dentate gyrus, reduced the levels of inflammatory factors IL-1β, TNF-α, and IL-6 in the hippocampus, and down-regulated the expression levels of TLR4, p-NF-κB P65/NF-κB P65, p-IκBα/IκBα, and NLRP3 proteins in the hippocampus. In conclusion, Erjing Pills can improve the learning and memory ability of the rat model of AD presumably by improving the activation of microglia, reducing the expression levels of neuroinflammatory factors IL-1β, TNF-α, and IL-6, inhibiting the TLR4/NF-κB/NLRP3 neuroinflammation pathway, and decreasing hippocampal deposition of Aβ and expression of p-Tau, thereby restoring the hippocampal morphological structure.

Aim To investigate the effects of long non-coding RNA(lncRNA)UNC5B-AS1 on the proliferation and epithelial mesenchymal transformation(EMT)of cervical cancer. Methods GEO and TCGA databases were used to download data sets and differential expression analysis was performed. qRT-PCR was used to verify the differential expression of lncRNA UNC5B-AS1 in normal and cancerous cervical tissues.The interference and overexpression of lncRNA UNC5B-AS1 were transfected into cervical cancer cell lines, and plate cloning, CCK-8 and EdU experiments were used to detect the effect of lncRNA UNC5B-AS1 on the pro-liferation of cervical cancer cells.Transwell assay was used to detect its effect on migration and invasion of cervical cancer cells.The expression levels of EMT-related genes E-Cadherin, N-Cadherin and Vimentin were detected by Western blot. Transcriptome sequencing was used to obtain the signal pathway regulated by lncRNA UNC5B-AS1, and to verify the expression level of related genes. Results RNA microarray and bioinformatics analysis showed that the expression level of lncRNA UNC5B-AS1 in cervical cancer was significantly higher than that in normal cervical tissue, and correlated with the overall survival time of patients.Compared with the negative control group, knockdown lncRNA UNC5B-AS1 could reduce the proliferation, migration and invasion of cervical cancer cells, while overexpression could promote the proliferation, migration and invasion of cervical cancer cells. Western blot showed that lncRNA UNC5B-AS1 could regulate EMT of cervical cancer cells. Transcriptome sequencing showed that lncRNA UNC5B-AS1 could regulate Toll like receptor(TLR)signaling pathway. qRT-PCR and Western blot results showed that the expression levels of TLR-related genes IL-6 and TICAM2 in the knockdown and overexpression lncRNA UNC5B-AS1 group were significantly changed(P<0.05). Conclusions LncRNA UNC5B-AS1 is highly expressed in cervical cancer. Overexpression of lncRNA UNC5B-AS1 may enhance TLR signaling pathway activity, thereby promoting proliferation and EMT of cervical cancer cells.

BACKGROUND: Patients with atrial fibrillation (AF) and prior stroke history have a high risk of cardiovascular events despite anticoagulation therapy. It is unclear whether catheter ablation (CA) has further benefits in these patients. METHODS: AF patients with a previous history of stroke or systemic embolism (SE) from the prospective Chinese Atrial Fibrillation Registry study between August 2011 and December 2020 were included in the analysis. Patients were matched in a 1:1 ratio to CA or medical treatment (MT) based on propensity score. The primary outcome was a composite of all-cause death or ischemic stroke (IS)/SE. RESULTS: During a total of 4.1 ± 2.3 years of follow-up, the primary outcome occurred in 111 patients in the CA group (3.3 per 100 person-years) and in 229 patients in the MT group (5.7 per 100 person-years). The CA group had a lower risk of the primary outcome compared to the MT group [hazard ratio (HR) = 0.59, 95% CI: 0.47-0.74, P < 0.001]. There was a significant decreasing risk of all-cause mortality (HR = 0.43, 95% CI: 0.31-0.61, P < 0.001), IS/SE (HR = 0.73, 95% CI: 0.54-0.97, P = 0.033), cardiovascular mortality (HR = 0.32, 95% CI: 0.19-0.54, P < 0.001) and AF recurrence (HR = 0.33, 95% CI: 0.30-0.37, P < 0.001) in the CA group compared to that in the MT group. Sensitivity analysis generated consistent results when adjusting for time-dependent usage of anticoagulants. CONCLUSIONS In AF patients with a prior stroke history, CA was associated with a lower combined risk of all-cause death or IS/SE. Further clinical trials are warranted to confirm the benefits of CA in these patients.

Objective: To analyze the epidemiological characteristics and spatiotemporal clustering of hepatitis A in Zhejiang Province from 2010 to 2019. Methods: The data of hepatitis A incidence in Zhejiang Province from 2010 to 2019 were collected from the infectious disease surveillance system of China Information System for Disease Control and Prevention. ArcGIS 10.7 software was used for spatial autocorrelation analysis. SaTScan 9.6 software was used for spatiotemporal scanning analysis. SPSS 25.0 software was used for additional analysis. Results: Zhejiang Province has reported 5 465 cases of hepatitis A in 2010-2019 years, with an average annual incidence rate of 1.00/100 000, and periodicity and seasonality are not obvious. The incidence of male was higher than that of female (P=0.023), and the highest incidence rate was 50-59 years old. Spatial autocorrelation analysis showed that there was a positive spatial correlation between the incidence of hepatitis A in Zhejiang Province from 2010 to 2017, with the weakest correlation in 2010 (Moran's I =0.103, Z=1.769, P=0.049), and the strongest correlation in 2016 (Moran's I=0.328, Z=4.979, P=0.001). Spatiotemporal scanning analysis showed that there was spatial aggregation of hepatitis A in Zhejiang Province from 2010 to 2019, with a total of three aggregation areas identified. Among them, the mostly aggregation area was concentrated in Xiangshan county of Ningbo city, which covered 10 counties (cities and districts), including Ninghai county and Yinzhou district, and appeared from January 1 to June 30, 2012. Conclusion: The incidence level of hepatitis A in Zhejiang Province shows a stable fluctuation trend from 2010 to 2019, and the seasonal regularity is not obvious. The population group aged 50-59 years old is the key population. There is spatial aggregation in the epidemic situation of hepatitis A. Targeted prevention and control measures of hepatitis A should be done based on the law of spatiotemporal aggregation and local incidence.

Objective: To establish a three-dimensional model of middle ear-eustachian tube based on Chinese digital visual human dataset, and the deformation and pressure changes of the middle ear-eustachian tube system after eustachian tube opening are simulated by computer numerical simulation. Methods: The first female Chinese Digital Visual Human data was adopted. The images were imported by Amira image processing software, and the images were segmented by Geomagic software to form a three-dimensional model of middle ear-eustachian tube system, including eustachian tube, tympanum, tympanic membrane, auditory ossicles, and mastoid air cells system. The 3D model was imported into Hypermesh software for meshing and analysis. The structural mechanics calculation was carried out by Abaqus, and gas flow was simulated by Xflow. The tissue deformation and middle ear pressure changes during eustachian tube opening were numerically simulated by fluid-solid coupling algorithm. Several pressure monitoring points including tympanum, mastoid, tympanic isthmus, and external auditory canal were set up in the model, and the pressure changes of each monitoring point were recorded and compared. Results: In this study, a three-dimensional model of middle ear-eustachian tube and a numerical simulation model of middle ear ventilation were established, including eustachian tube, tympanum, mastoid air cells, tympanic membrane, and auditory ossicles. The dynamic changes of the model after ventilation could be divided into five stages according to the pressure. In addition, the pressure changes of tympanum and tympanic isthmus were basically synchronous, and the pressure changes of mastoid air cells system were later than that of tympanum and tympanic isthmus, which verified the pressure buffering effect of mastoid. The extracted pressure curve of the external auditory canal was basically consistent with that of tympanometry in terms of value and trend, which verified the effectiveness of the model. Conclusions: The numerical simulation model of middle ear-eustachian tube ventilation established in this paper can simulate the tissue deformation and middle ear pressure changes after eustachian tube opening, and its accuracy and effectiveness are also verified. This not only lays a foundation for further research, but also provides a new research method for the study of middle ear ventilation.

ObjectiveTo explore the value of plasma free metanephrines， including metanephrine（MN） and normetanephrine（NMN）， collectively referred to as MNs in the diagnosis of pheochromocytoma and paraganglioma （PPGL）. MethodsThe study included 1 631 patients suspected of PPGL from December 2014 to December 2020 in SunYat-sen Memorial Hospital. In these subjects， Plasma free MNs were measured by liquid chromatography-tandem mass spectrometry（LC-MS/MS） before surgery. Receiver operating characteristic （ROC） curves were used to determine the sensitivity and specificity of plasma NMN and MN in the diagnosis of PPGL. ResultsOf the screened patients， 108 patients had pathologically confirmed PPGL and 1 523 patients had definitive diagnoses other than PPGL as a control group. The median value of plasma MN ［0.54（0.17~4.48） nmol/L vs. 0.15（0.11~0.21） nmol/L， P<0.001］ and NMN ［7.48（2.12~15.01） nmol/L vs. 0.32（0.22~0.46） nmol/L， P<0.001］ were significant higher in the PPGL group than in the control group. Using an upper cut-off of 0.395 nmol/L for MN， the sensitivity was 60.2% and the specificity was 97.8%； when using a cut-off of 1.105 nmol/L for NMN， the diagnostic sensitivity was 87.0%， and the specificity was 98.7%. The area under the ROC curve and 95% confidence interval of plasma MN and NMN combined were 0.800（0.743， 0.858）， 0.959（0.932， 0.98） and 0.970（0.944， 0.996）， respectively. Analyzing the false-positive results， it was found that in the control group， 3% of the false-positive cases appeared. The estimated glomerular filtration rate（eGFR） were significantly lower in the false-positive group than in the true-negative group ［74.42（51.04~96.96） mL/min vs. 88.51（72.80~101.83） mL/min， P=0.001］. In 212 patients with eGFR lower than 60 mL/min， the false positive rate was increased to 8%. If the upper limit of the reference interval was increased by 25%， the specificity was increased to 96.7%； when the upper limit of the reference interval was increased by 50%， the specificity was 98.6 %. ConclusionsPlasma free MNs has a great reliability in the diagnosis of PPGL. The negative predictive value is extremely high and close to 100%. Combination analysis of plasma MN and NMN can further improve diagnostic performance. However， a few false positive cases may appear and might be influenced by impaired renal function. In patients with eGFR lower than 60 mL/min， the false positive rate is significantly increasing， which need a 25%-50% increase in the expected upper limit of a reference range to guarantee high specificity.
