ObjectiveTo explore the target of Erzhiwan in reducing myocardial injury in ovariectomized mice through non-targeted myocardial metabolomics combined with experimental verification. MethodsOvariectomized mouse model was selected, 40 female C57BL/6 mice were randomly divided into sham operation group, model group, estrogen group(estradiol valerate, 1.3×10-4 g·kg-1), Erzhiwan low and high dose groups(3.12, 9.36 g·kg-1), with 8 mice in each group. Each administration group was given the corresponding dose of Erzhiwan by gavage, and the sham operation group and model group were given equal volume of distilled water by gavage for 12 weeks. Echocardiography was used to detect cardiac function, hematoxylin-eosin(HE) staining was used to observe myocardial morphological changes, and enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of estrogen, N-terminal pro-brain natriuretic peptide(NT-proBNP), hypersensitive troponin T(hs-TnT), total cholesterol(TC), triglyceride(TG), low density lipoprotein cholesterol(LDL-C), high density lipoprotein cholesterol(HDL-C), interleukin(IL)-1β, IL-18 and tumor necrosis factor-α(TNF-α). The non-targeted metabolomics of mouse myocardium were analyzed by ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS), and the differential metabolites and corresponding metabolic pathways were obtained. The mRNA expression levels of phosphatidylinositol 3-kinase(PI3K) and protein kinase B(Akt) in mouse myocardial tissues were detected by real-time fluorescence quantitative polymerase chain reaction(Real-time PCR), and the protein expression levels of PI3K, Akt, phosphorylated(p)-Akt were detected by Western blot. ResultsCompared with the sham operation group, the model group showed abnormal cardiac function, increased myocardial fiber space, cardiomyocyte atrophy, sarcoplasmic aggregation, and occasional dissolution or rupture of muscle fiber, the level of estrogen in the serum was decreased, the levels of NT-proBNP, hs-TnT, IL-1β, IL-18, TNF-α, TG, TC and LDL-C were increased, and the level of HDL-C was decreased(P<0.01). Compared with the model group, Erzhiwan could increase the level of estrogen, improve the abnormal cardiac function, reduce the pathological injury of myocardial tissue, decrease the levels of myocardial injury markers(NT-proBNP, hs-TnT) and inflammatory factors(IL-1β, IL-18, TNF-α), decrease the levels of TG, TC, LDL-C, and increased the level of HDL-C(P<0.01). The results of non-targeted myocardial metabolomics showed that 31 of the 162 differential metabolites between the model group and sham operation group were significantly adjusted after administration of Erzhiwan, which were mainly glycerol phospholipid metabolites. Pathway enrichment results showed that Erzhiwan mainly affected glycerophospholipid metabolic pathway, PI3K-Akt pathway, cyclic guanosine monophosphate(cGMP)-protein kinase G(PKG) pathway and other metabolic pathways. Compared with the sham operation group, the levels of phosphatidylcholine(PC, 11 types) and phosphatidylethanolamine(PE, 5 types) in mouse myocardial tissue of the model group were increased(P<0.05, P<0.01), and the mRNA and protein expressions of PI3K and p-Akt were decreased(P<0.05, P<0.01). Compared with the model group, the levels of PC(11 types) and PE(5 types) were decreased(P<0.05, P<0.01) in myocardial tissue of Erzhiwan group, the mRNA and protein expressions of PI3K and p-Akt were elevated(P<0.01). ConclusionErzhiwan can alleviate the pathological injury of myocardium in ovariectomized mice, improve the abnormal cardiac function, improve lipid metabolism disorder, and reduce the levels of myocardial injury markers and inflammatory factors, which involves a number of signaling and metabolic pathways in the heart, among which glycerophospholipid metabolism pathway and PI3K/Akt pathway may have key roles.

Objective:
To evaluate the intervention efficacy of integrated group social skills training on social ability in school age patients with high functioning ASD, so as to provide a reference for improving social skills in children with high functioning ASD.
Methods:
From January 2021 to December 2023, 62 children aged 7-12 with high functioning ASD who visited the Children s Psychiatry Outpatient Department of the Affiliated Kangning Hospital of Ningbo University were recruited, and were randomly divided into a training ( n =31) and a control group ( n =31) by a random number table method. The training group received a 20 week structured group social training program (mental interpretation courses and social courses), while the control group received only conventional treatment. Chinese version of Griffith Empathy Measure Parent Ratings (GEM-PR) and Social Response Scale (SRS) were used to assess the symptoms of social deficits before and after treatment. Emotional face recognition tasks and eye movement trajectories were used to test the characteristics of social visual attention in children with ASD. Group comparison was conducted using t-test and Mann-Whitney U test.
Results:
At baseline, there were no significant differences in GEM-PR score ( t = -1.20 to -0.81), SRS score ( t =-0.36-1.75), emotional face recognition accuracy and reaction time ( t =-0.58-1.85), and eye movement trajectory ( U/t =-1.63-0.29) between the two group ( P >0.05). After intervention, the total GEM-PR score and empathic cognitive factor score of training group [18.00(10.00,24.00),9.00(8.00,13.00)] were significantly higher than those of the control group [12.00(-1.00,18.00),2.00(-2.00,7.00)], and the total SRS score and social cognition, social perception, social communication, social motivation (73.23±14.20, 16.16±2.72, 6.58±2.50, 24.29±5.61, 9.52±3.73) were significantly lower than those of the control group (95.26±15.29, 19.90±2.84, 12.58±2.49,31.94±6.38, 13.74±4.81) ( U/t =-2.38, -4.59; -5.88, -5.29, -9.47, -5.01, -3.87, P <0.05). The overall correct rate of emotional face recognition and the correct rate of angry, fearful and neutral faces recognition in the training group [(81.55±6.62)%,(76.86±12.06)%,(79.61±12.42)%,(94.27±6.26)%] were significantly higher than the control group [(70.55±13.82)%,(62.82±18.77)%,(67.18±18.85)%,(79.60±20.05)%], and the average reaction time [(2 226.70±274.43)ms] was lower than the control group [(2 417.27±324.10)ms] (t=4.00, 3.50, 3.07, 3.89, -2.42, P<0.05). The time to first eye gaze [764.74 (748.64, 793.73) ms] in the training group was significantly lower than that in the control group [810.92 (782.86, 877.42) ms], and the proportion of moderatetohigh intensity attention area in the face [(37.37±1.27)%] was significantly higher than that in the control group [(30.34±1.23)%] (U/t=3.44, 8.89, P<0.05).
Conclusion
Integrated group social training can significantly improve the social communication and empathy ability of high functioning ASD children, increase active attention and recognition ability of faces, and improve mental development of children with ASD.

ObjectiveTo investigate the effect of blue light on emmetropization in guinea pigs, explore the potential mechanisms and assess its application in myopia prevention and control. MethodsThree-week-old male guinea pigs (n=20) were randomly assigned to the white light group and the blue light group. Refraction and ocular biological parameters were measured every 2 weeks until the experiment ended at week 8. And the 4D-data-independent acquisition (4D-DIA) proteomics technology was used to analyze retina from both the blue light and white light groups, exploring protein composition, expression differences, and biological functions. ResultsAfter 2 weeks, Guinea pigs exposed to white light gradually tended towards emmetropia, showing a statistically significant difference in refractive error compared to the blue light group (P<0.001). From week 4, the axial length of the blue light group was significantly shorter than that of the white light group (P<0.05). Meanwhile, the vitreous chamber length in the blue light group was significantly smaller than that of the white light group from week 2 (P<0.05). A total of 161 differentially expressed proteins were identified by proteomics technology in the retina, with 98 proteins upregulated and 63 proteins downregulated. These proteins were primarily enriched in biosynthetic pathways such as vesicle transport, redox reaction, niacin and nicotinamide metabolism and NAD+ metabolism. ConclusionsGuinea pigs raised under blue light exhibit hyperopic drift and slowed axial elongation, which slows the procession of emmetropization. Based on the 4D-DIA technology, the differentially expressed proteins between the blue light and white light groups are primarily involved in NAD+ metabolism, niacin and nicotinamide metabolism. Especially in NAD+ salvage synthesis, nicotinamide phosphoribosyl transferase (NAMPT) is upregulated, while sirtuin 2 (SIRT2) is downregulated. It provides new insights into the mechanism of blue light in emmetropization and a theoretical basis for myopia prevention and control.

In the context of global climate change, the impact of ambient temperature change on cardiovascular health has become increasingly significant. Epidemiological studies have shown that both high and low temperature can lead to the occurrence of adverse cardiovascular outcomes. For example, exposure to low temperature and high temperature, and diurnal temperature difference can increase the risk of cardiovascular diseases (CVD) mortality. Exposure to cold and heat, heatwaves and cold spells may induce myocardial infarction. Low temperature, high temperature and variations in temperature can increase the risk of heart failure. There are complex interactions among the effects of temperature and humidity, wind speed, radiation, precipitation and air pollution on adverse cardiovascular outcomes. Valnerable groups such as the elderly, patients with chronic diseases, and outdoor workers are particularly susceptible to temperature-related CVD risks. The mechanisms by which temperature affects adverse cardiovascular outcomes involves hemodynamic changes, autonomic nervous system dysregulation, blood rheology alterations, as well as inflammation and metabolic abnormalities, but many research gaps remain. Future studies should conduct in-depth research on mechanisms, individual differences, climate change impacts, and public health interventions to provide more effective policies and interventions to reduce the burden of CVD.

Objective:
To develop and validate a health literacy assessment scale for junior high school students, providing an effective tool for evaluating and monitoring health literacy among Chinese adolescents.
Methods:
Based on school health education policy documents, a health literacy assessment framework was constructed, comprising five horizontal and four vertical dimensions. From May to June and August to September in 2024, the framework was refined through Delphi expert consultations and focus group discussions, leading to the development of the Health Literacy Assessment Scale for Junior High School Students. In September 2024, a convenience sample of 625 students from three junior high schools in Beijing and Tianjin completed the questionnaire. Item analysis, reliability, and validity tests were conducted to evaluate the scale.
Results:
The recovery rate for two rounds of expert consultation questionnaires was 100%. The expert authority coefficients ( Cr ) were 0.86 and 0.87 respectively (both >0.70), with Kendall W values of 0.34 and 0.27 ( P <0.05). The focus group discussions followed a rigorous structure, and after multiple rounds of item screening and revision, the version 3.0 of the junior high school students health literacy assessment scale was developed, comprising 57 items. Three items that failed to meet the comprehensive screening criteria were preliminarily removed, and the final scale contained 54 items. The scale demonstrated excellent reliability, with an overall Cronbach s α coefficient of 0.92 and split half reliability of 0.93. Confirmatory factor analysis [ χ 2/df =2.094, root mean square error of approximation ( RMSEA )=0.042, comparative fit index ( CFI )=0.911, Tucker Lewis index ( TLI )=0.907] indicated good model fit indices.
Conclusions
The preliminary development of the health literacy assessment scale for junior high school students follows a rigorous item screening process with well designed dimensions, demonstrating good reliability and validity, thus serving as an appropriate evaluation tool for adolescent health literacy.

Objective:
To analyze the prevalence and determinants of comorbid overweight/obesity and elevated blood pressure among primary and secondary school students in Yangzhou City, and to explore the association between sleep patterns, eating behavior and the comorbidity of overweight/obesity and elevated blood pressure, so as to provide reference for developing prevention strategies targeting common comorbidities in students.
Methods:
By using stratified cluster random sampling, a total of 8 735 primary and secondary school students were selected from 36 schools in six counties of Yangzhou from October to November 2023. Students underwent physical examinations and a questionnaire survey was conducted using the questionnaire on students health status and influencing factors. The Chi square test was used to compare the detection rate of comorbid overweight/obesity and elevated blood pressure in different groups of primary and secondary school students. The Logistic regression model was used to explore the association between sleep and dietary behaviors and their combined effects and coexistence.
Results:
The detection rate of comorbid overweight/obesity and elevated blood pressure among primary and secondary school students in Yangzhou was 9.85%, which was higher among boys (12.14%) than girls (7.59%)( χ 2=50.86, P <0.01). After controlling for gender, residence, educational stage, parental education, smoking, drinking, and moderate to vigorous exercise, multivariate Logistic regression analysis showed that irregular breakfast consumption and inadequate daily sleep were associated with a higher risk of comorbidities compared with regular breakfast consumption and adequate daily sleep among overall and primary school students (overall: OR =1.52, 95% CI =1.18- 1.96 , primary school students: OR =2.79, 95% CI =1.61-4.82)(both P <0.05). From the perspective of primary school students of different genders, the risk of comorbidities in girls who consumed breakfast irregularly and had inadequate daily sleep was 3.59 times higher than that in girls who consumed breakfast irregularly and had inadequate daily sleep (95% CI =1.65-7.82, P <0.01).
Conclusion
The sleep patterns and breakfast behaviors of primary and secondary school students are found to be associated with comorbid overweight/obesity and elevated blood pressure, especially in primary school girls.

Objective: To investigate the distribution of IgM anti-A/B titers among group O whole blood donors in Jiangsu, establish a low-titer threshold, and analyze the demographic characteristics of low-titer donors, so as to provide data for recruiting low-titer group O whole blood (LTOWB) donors. Methods: Plasma samples from 1 009 group O whole blood donors were tested for IgM anti-A and anti-B titers using the microplate technique. The distribution of antibody titers was analyzed to establish a low-titer threshold. The distribution trends of titers across different demographic groups were also analyzed. Results: The peak titer for anti-A, anti-B were 64 (31.5%), 4 (23.8%), respectively, The proportion of donors with both anti-A and anti-B titers below 64 was 97.3% (982/1 009). The mean anti-A titer was higher than anti-B titer. Anti-A titers were higher in female donors than in male donors (P<0.05). The anti-A titers differed significantly among different age groups (P<0.05). However, no significant difference in titers was observed based on the number of donations (P>0.05). Conclusion: A titer of 64 can be used as the reference threshold of LTOWB in Jiangsu. Male donors of appropriate age are more suitable than female donors for establishing an emergency panel of LTOWB mobile donors.
