Objective: To investigate the relationship between daily outdoor activity time both on and off campus and respiratory symptoms of junior middle school students, then to provide evidence for the prevention of respiratory diseases in adolescents. Methods: In 2016, two middle schools were selected in Wuhan，in which a total of 860 eighth grade students were surveyed, generalized linear analysis was conducted by SAS 9.4 software. Results: Average outdoor activity time out of campus during weekdays in boys and was (1.84±2.30) hours, which was higher than in girls (1.51±1.99) hours (t=2.19, P<0.05). Average outdoor activity time in campus in boys was (1.74±1.50) hours, which was significantly higher than that of girls (1.49±1.20) hours (t=2.68, P<0.05). According to the results of generalized linear analysis, after controlled for gender, age and self-perceived physical condition, the longer the time adolescents spent outside the classroom during weekday, the less likely they were to have symptoms of throat and nasal cavity(estimated value=-0.06,-0.07, P<0.05). Conclusion Adolescents who spend more time outside the classroom during weekday can effectively prevent the occurrence of respiratory related diseases.

Objective:To construct a combined radiomics model based on preoperative enhanced computed tomography (CT) examination for predicting microvascular invasion (MVI) in hepatocellular carcinoma (HCC), and provide biological explanations for the radiomics model.Methods:The retrospective cohort study was conducted. The messenger RNA (mRNA) of 424 HCC patients, the clinicopathological data of 39 HCC patients entered into the Cancer Genome Atlas database from its establishment until January 2023, and the clinicopathological data of 53 HCC patients who were admitted to the Gansu Provincial People′s Hospital from January 2020 to January 2023 were collected. The 92 HCC patients were randomly divided into a training dataset of 64 cases and a test dataset of 28 cases with a ratio of 7∶3 based on a random number table method. The CT images of patients in the arterial phase and portal venous phase as well as the corresponding clinical data were analyzed. The 3Dslicer software (version 5.0.3) was used to register the CT images in the arterial phase and portal venous phase and delineate the three-dimensional regions of interest. The original images were preprocessed and the corresponding features were extracted by the open-source software FAE (version 0.5.5). After selecting features using the Least Absolute Shrinkage and Selection Operator, the radiomics model was constructed and the radiomics score (R-score) was calculated. The nomogram was constructed by integrating clinical parameters, imaging features and R-score based on Logistic regression. The gene modules related to radiomics model were obtained and subjected to enrichment analysis by conducting weighted gene co-expression network analysis and correlation analysis. Observation indicators: (1) comparison of clinical characteristics of patients with different MVI properties; (2) establishment of MVI risk model; (3) evaluation of MVI risk model; (4) clustering of gene modules; (5) functional enrichment of feature-correlated gene modules. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Comparison of count data was conducted using the chi-square test. The intra-/inter-class correlation coefficient (ICC) was used to assess the inter-observer consistency of radiomics feature extracted by different observers. ICC >0.75 indicated a good consistency in feature extraction. The Logistic regression model was used for univariate and multivariate analyses. The receiver operating characteristic curve was drawn, and the area under curve (AUC), the decision curve and the calibration curve were used to evaluate the diagnostic efficacy and clinical practicality of the model. Results:(1) Comparison of clinical characteristics of patients with different MVI properties. Of 92 HCC patients, there were 47 cases with MVI-positive and 45 cases with MVI-negative, and there were significant differences in hepatitis, tumor diameter, peritumoral enhancement, intratumoral arteries, pseudocapsule and smoothness of tumor margin between them ( χ2=5.308, 9.977, 47.370, 32.368, 21.105, 31.711, P<0.05). (2) Establishment of MVI risk model. A total of 1 781 features were extrac-ted from arterial and portal venous phases of the intratumoral and peritumoral regions. After feature dimension reduction, 8 radiomics features were selected from arterial and portal venous phases to construct the combined model. Results of multivariate analysis showed that peritumoral enhancement, intratumoral arteries, pseudocapsule, smoothness of tumor margins, and R-score were independent risk factors for MVI in patients with HCC [ hazard ratio=0.049, 0.017, 0.017, 0.021, 2.539, 95% confidence interval ( CI) as 0.005-0.446, 0.001-0.435, 0.001-0.518, 0.001-0.473, 1.220-5.283, P<0.05]. A nomogram model was constructed incorporating peritumoral enhancement, intratumoral arteries, pseudocapsule, smoothness of tumor margins, and R-score. (3) Evaluation of the MVI risk model. The AUC of radiomics model was 0.923 (95% CI as 0.887-0.944) and 0.918 (95% CI as 0.894-0.945) in the training dataset and test dataset, respectively. The AUC of nomogram model, incorpora-ting both the R-score and radiomics features, was 0.973 (95% CI as 0.954-0.988) and 0.962 (95% CI as 0.942-0.987) in the training dataset and test dataset, respectively. Results of decision curve showed that the nomogram had better clinical utility compared to the R-score. Results of calibration curve showed good consistency between the actual observed outcomes and the nomogram or the R-score. (4) Clustering of gene module. Results of weighted gene co-expression network analysis showed that 8 gene modules were obtained. (5) Functional enrichment of feature-related gene modules. Results of correlation analysis showed 4 gene modules were significantly associated with radiomics features. The radiomics features predicting of MVI may be related to pathways such as the cell cycle, neutrophil extracellular trap formation, and PPAR signaling pathway. Conclusions:The combined radiomics model based on preoperative enhanced CT imaging can predict the MVI status of HCC. By obtaining mRNA gene expression profiles associated with radiomics features, a biological interpretation of the radiomics model is provided.

Objective: To investigate the relationship among depression, anxiety, stress and addictive substance use behavior in secondary vocational students. Methods: Cluster sampling method and the Adolescent Health-related Behaviors Questionnaire were used to collect demographic characteristics, psychological symptoms, and addictive substance usage among 5 935 students in nine vocational schools in Chongqing, Zhaoqing, Ningbo, and Taiyuan. Multivariate logistic regression analysis was used to analyze the relationship between the addictive substance use behavior and psychological factors. Results: The detection rates of depression, anxiety and stress were 46.5% (n=2 762), 58.7% (n=3 483), and 29.8% (n= 1 770), respectively. The prevalence of addictive substances was 74.8% (n=4 440), traditional drugs was 0.8% (n=50), new drugs was 2.8% (n=166), other addictive drugs was 4.1% (n=241). Multivariate logistic regression analysis showed that compared with the normal psychological states of secondary vocational students, the OR value of mild depression tendency alcohol and tobacco use behavior of secondary vocational students was 1.45; the OR values of mild anxiety, moderate anxiety, severe anxiety and very serious anxiety were 1.46, 1.46, 1.71, and 1.83, respectively; the traditional drugs use behaviors were 5.51, and 2.61, respectively, for the severe anxiety and very serious anxiety. Compared with the normal psychological state of secondary vocational students, the OR values of the severe anxiety and very severe anxiety were 2.56, and 2.66, respectively, for severe anxiety and very serious anxiety. Compared with normal psychological status of secondary vocational students, the OR values of mild, moderate, severe, and very severe anxiety were 2.14, 2.47, 2.39, and 3.45, respectively; all P values <0.05. Conclusion Anxiety and mild depression were risk factors of tobacco and alcohol use in secondary vocational students; severe and above anxiety were the risk factors of drug use in secondary vocational students; anxiety was the risk factor for other addictive drug use in secondary vocational students.

Objective: To investigate the indications and long-term outcomes of endoscopy-assisted removal of parotid gland calculi via a transoral approach. Methods: From August 2005 to December 2016, 158 consecutive patients with parotid gland calculi underwent endoscopy-assisted lithectomy transorally. They included 71 males and 87 females, with an age of 5-84 years. The immediate safety and effectiveness were evaluated. After surgery, the patients were followed up, and gland function was analyzed on the basis of clinical manifestations, sialography, scintigraphy and sialometry. Postoperative sialograms were categorized into 2 types: ①type Ⅰ, the main duct was normal or had ectasia and stenosis, but no persistent contrast was seen on the functional film; ②type Ⅱ, the main duct had ectasia or stenosis, with persistent contrast media on the functional film. Results: Under one endoscopic procedure, the stones (or foreign bodies) were completely removed in 134 cases and almost completely removed in 10 cases, with a success rate of 91.1% (144/158). Of the 144 successful cases, the treatment options included direct basket retrieval or forceps grasping in 77 cases, basket entrapment with direct ostium incision in 36, basket capture with perio-ostium incision in 23 and perio-ostium incision in 8 cases with impacted stones. In two of the initial 14 failure cases, the stones were discharged spontaneously 3 months after operation. During 3-120 months′ follow-up (mean 36 months) of the 146 patients, one had recurrent stone, two developed ductal obturation, 16 had mild symptoms, and the remaining 127 cases were asymptomatic. Of the postoperative sialograms in 34 stone-free patients 25 were type Ⅰ, 9 were type Ⅱ. Both scintigraphy and saliva flow rate indicated an improvement of the affected gland function in some degree (P<0.05). Conclusions Transoral endoscopy-assisted removal of parotid gland calculi is a safe and effective technique. It is mainly indicated for mobile stones in the main duct or impacted stones in the anterior third of the Stensen′s duct. Sialography, scintigraphy and sialometry show postoperative improvement of gland function in most of the cases.

Objective To investigate the epidemiological characteristics of major kidney disease deaths and the potential years of life lost among residents in Wuhan from 2014 to 2019, and to provide a scientific basis for the prevention and treatment of kidney diseases. Methods The major kidney diseases deaths among residents in Wuhan during 2014-2019 were collected from the population-based Mortality Surveillance System. The standardized mortality rate and potential years of life lost rate (PYLLR) of major kidney diseases among residents in different ages and genders were calculated, and the epidemiological characteristics and trends were analyzed. Results There were 4 100 deaths (2 380 in male and 1 720 in female) from major kidney diseases among residents in Wuhan between 2014 to 2019, with an age-standardized mortality rate of 6.22/100 000. The mortality rate of major kidney diseases showed an upward trend with the increasing age groups. The age-standardized mortality rate and the age-standardized potential years of life lost rate (SPYLLR) in glomerular disease and tubulo-interstitial diseases were significantly decreased (P＜0.05). The age-standardized mortality rate of the kidney failure was significantly increased (P＜0.05), especially in the male (APC=25.10% , P＜0.05). Conclusion From 2014 to 2019, there was no significant change in the overall mortality rate of major kidney diseases among residents in Wuhan. The death burden and disease burden of glomerular diseases and tubulo-interstitial diseases were significantly decreased, while the mortality rate of male kidney failure was significantly increased, indicating the need for targeted prevention and treatment of kidney diseases.
