Objective: To investigate the prevalence of overweight and obesity among children and adolescents in Yangzhou City, and its association with screen behaviors, so as to provide scientific evidence for weight management among students. Methods: In May 2025, an electronic questionnaire survey was conducted among children and adolescents in Yangzhou City. A total of 3 722 participants were selected from grades 4 to 12 in 18 primary and secondary schools (108 classes) by using stratified cluster random sampling. The Chi square test was used to compare the differences in the detection rates of overweight and obesity among children and adolescents with 5 types of screen behaviors (watching TV, playing electronic games, scrolling short videos, screen based learning, electronic socializing) in different time groups each day (never, >0~<2 h, ≥2 h). Multivariate Logistic regression analysis was performed to examine the associations of five types of screen behaviors, presence of electronic devices in the bedroom, and screen use during meals on the weight status of children and adolescents. Results: The prevalence of overweight and obesity among children and adolescents was 37.3%. For all five types of screen behaviors, the differences in the distribution of overweight and obesity detection rates among children and adolescents across the three time spent categories were statistically significant ( χ 2=30.76- 70.78 , all P <0.01). After adjusting for confounding factors, multivariate Logistic regression analysis revealed that frequent or always using screens during meals( OR =1.63, 95％ CI =1.14~2.31), playing video games ( OR =1.28, 95% CI =1.11-1.48), browsing short videos ( OR =1.29, 95％ CI=1.09-1.54), and screen based learning ( OR =1.26, 95％ CI =1.10-1.44) were significantly associated with overweight and obesity among children and adolescents (all P <0.05). Conclusions Excessive screen use is positively correlated with the incidence of overweight and obesity in children and adolescents. Targeted interventions on screen behaviors among children and adolescents are therefore warranted.

This paper aims to discuss the construction and promotion strategy of medical care capacity framework based on the core literacy of palliative care， combining domestic and foreign research and clinical status. The research results show that it is particularly important to construct a framework of medical care competence based on palliative care. The core competencies required for palliative care include the ability to comprehensively evaluate and formulate personalized programs， effective communication skills， interdisciplinary teamwork skills， and the ability to continuously learn and improve themselves. The quality of care can be further improved if the above abilities are incorporated into the framework of medical care ability based on palliative care. However， there are a series of problems in the process of constructing the framework of palliative medical care capacity， such as difficult implementation of policy support， poor professionalism of talent team， single and irregular service model， low social acceptance， and difficult interdisciplinary cooperation and resource integration. After a detailed analysis of the problems， this paper puts forward the countermeasures to construct the framework of caring ability literacy based on palliative care. Effective countermeasures such as increasing policy support， cultivating comprehensive talents， developing diversified palliative care models， improving social recognition， and strengthening interdisciplinary cooperation and resource integration can effectively improve the core literacy and professional ability of medical care personnel， and then promote the development and improvement of palliative care services. In-depth discussion of the above contents can provide scientific reference for building a care model and literacy framework with palliative care as the core.

【Objective】 To investigate the matrix effect on the determination of potency in Recombinant Human Coagulation Factor Ⅷ for Injection (rFⅧ). 【Methods】 Two different detection matrices were used to establish two methods for detecting the potency in Recombinant Human Coagulation Factor Ⅷ for Injection. And the matrix effect on the determination of potency was determined, including specificity, linearity, repeatability, accuracy and intermediate precision. 【Results】 As to the specificity, the recoveries of the two substrates at high vs low concentration level were 112% and 110% vs 104% and 109%, respectively. As to the linearity, in the range of (0.125-1.000) IU/mL, the correlation coefficient between concentration and coagulation time of standard/ sample was higher than 0.99. As to the accuracy/repeatability, the recoveries of two matrices was 104% and 102%, and RSD was 2.4% and 1.9%. As to the intermediate precision, personnel factor of two matrices was 0.72 and 0.23, date factor was 0.79 and 0.85, and RSD(for 12 times) was 4.2% and 3.0%. Comparison of two matrices was as follows: Deviation in test results of 6 batches of rFⅧ was all lower than 5%. There was no significant difference between two matrices. 【Conclusion】 The two matrices for potency detection show good performance including specificity, linearity, repeatability, accuracy, and intermediate precision. They are suitable for the determination of potency in rFⅧ products.

Objective: To explore the diagnostic value of serum glutamyltransferase (GGT) and osteopontin (OPN) for asymptomatic secondary common bile duct stones. Methods: A total of 150 gallbladder stones patients were divided into asymptomatic secondary common bile duct stones patients (common bile duct stones group) 34 cases and gallbladder stone group 116 cases. The difference of serum liver function indexes and OPN concentration between 2 groups were compared. Meanwhile, the diagnostic value of serum GGT combined with OPN was assessed by receiver operating characteristic curve. Results: There were no statistical difference in alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) and direct bilirubin (DBil) between 2 groups (P>0.05). The GGT, alkaline phosphatase (ALP) and OPN in common bile duct stones were significantly higher than those in gallbladder stone group: (141.57 ± 47.11) U/L vs. (77.26 ± 21.76) U/L, (150.10 ± 17.55) U/L vs. (137.65 ± 24.36) U/L and (16.21 ± 3.26) mg/L vs. (11.50 ± 3.99) mg/L, there were statistical differences (P<0.05). Logistic multivariate analysis showed that GGT, ALP and OPN were the independent risk factors of asymptomatic secondary common bile duct stones (P<0.05). The areas under curve of GGT and OPN in diagnosis of asymptomatic secondary common bile duct stones were significantly higher than ALP (P<0.05). Conclusions Serum GGT and OPN can be served as early predictors for the gallbladder stone combine with asymptomatic secondary common bile duct stones.

OBJECTIVE:To investigate protective effects of different doses of atorvastatin pretreatment on non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients underwent percutaneous coronary intervention (PCI). METHODS:A total of 81 NSTE-ACS patients in a hospital during Jan. 2014-Apr. 2016 were divided into high-dose group(40 cases)and low dose group(41 cases)according to random number table. High-dose group was given Atorvastatin calcium tablet 80 mg 12-24 h before PCI,and then 40 mg 2 h before PCI. Low-dose group was given Atorvastatin calcium tablet 10 mg 12-24 h before PCI. Fractional flow reserve(FFR),coronary flow reserve(CFR)and index of microcirculation resistance(IMR)after surgery were all observed in 2 groups. The levels of creatine kinase(CK),creatine kinase myocardial band(CK-MB)and high sensitive C-re-active protein (hs-CRP) were compared between 2 groups before and after surgery. RESULTS:There was no statistical signifi-cance in FFR and CFR after surgery between 2 groups (P>0.05);IMR of high-dose group was significantly lower than low-dose group,with statistical significance(P<0.05). There was no statistical significance in CK,CK-MB or CRP between 2 groups before surgery(P>0.05). After surgery,the levels of CK-MB and CRP in low-dose group were significantly higher than high-dose group,with statistical significance(P<0.05). There was no statistical significance in CK level between 2 groups after surgery (P>0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:During PCI,pre-treatment with high-dose of atorvastatin(80→40 mg)could effectively improve microcirculatory disturbance and inhibit inflammatory reaction of NSTE-ACS patients.

Objective To measure the chromatic differences of the tongue tip and tongue side and provide quantitative evidence for tongue color diagnosis. Methods Totally 683 healthy people were recruited, and their tongue photos were taken. Then ICC specific documents were used for the correction of all tongue photos, and chromatic values (L*, a*, b*, C*and h°) of tongue tip and tongue side were obtained for further statistical analysis. CIEDE2000 was used for calculating the color differences. Results The average color difference of tongue tip and tongue side in normal pink tongue was 5.4. When pink tongue has abnormal red tongue tip, the average color difference of tongue tip and tongue side was 10.85. Compared with normal tongue tip, the average color difference of tongue tip and tongue side in abnormal color tongue with abnormal red tongue tip increased from 5.4-7.0 to 11.23. Conclusion Red tongue tip is a sensitive sign indicating abnormal heat in the body. Tongue tip quantitative diagnosis is valuable in the determination of heat sign in TCM preventive treatment of disease, and reveal the diagnosis meaning and scientific connotation of red tongue tip.
