Objective: To investigate the annual trend and influencing factors of screening myopia prevalence among children and adolescents in Tianhe District, Guangzhou from 2021 to 2024, so as to provide a scientific basis for optimizing targeted and precise regional myopia prevention and control strategies. Methods: From 2021 to 2024, a stratified cluster random sampling method was adopted to recruit 10 132 students ranging from senior kindergarten to senior high school from fixed monitoring sites for myopia screening. Additionally, a questionnaire survey on myopia related factors was administered to 7 115 students in grade 4 and above. Generalized estimating equation (GEE) models were used to analyze the annual changing trends and interaction effects, and mixed effects models were performed for sensitivity analysis. Results: The screening myopia prevalence among children and adolescents in Tianhe District from 2021 to 2024 was 58.9%, 57.3%, 56.8%, and 54.7%, respectively, and showed a statistically significant difference ( χ 2=9.06, P <0.05). The prevalence rates among senior kindergarten, primary school, junior high school, regular senior high school, and vocational high school students were 8.7%, 40.7%, 74.3%, 86.7%, and 75.6%, respectively （χ 2= 2 493.11， P <0.05). The prevalence was significantly higher in female students (60.9%) than in male students (53.3%) ( χ 2= 59.22 , P <0.05). GEE analysis showed that male students ( OR =0.59), primary school students ( OR =0.45), those who spent less than 6 hours per day sitting indoors ( OR =0.78), and those who used electronic devices for no more than 2 hours per day ( OR = 0.25 ) all had lower risks of screening myopia (all P <0.05). Students in regular high schools ( OR =2.01), those who engaged in activities inside the classroom during breaks ( OR =1.55), those who engaged in activities outside the classroom but within the school building during breaks ( OR = 1.46), those who never or only occasionally maintained proper reading and writing postures ( OR =1.32), those with less than 2 hours of daily outdoor activity ( OR =1.86), those with both parents being myopic ( OR =2.48), those with only the father being myopic ( OR =1.50), and those with only the mother being myopic ( OR =1.63) all had higher risks of screening detected myopia (all P ＜0.05). Interaction effect analysis revealed annual heterogeneity in the effects of daily outdoor activity time ≥2 h and daily electronic device use time >2 h on screening myopia prevalence (all P ＜0.05). Conclusions The screening myopia prevalence among children and adolescents in Tianhe District, Guangzhou, demonstrates a continuous downward trend. The impacts of daily outdoor activity duration and electronic device usage time on screening myopia exhibit annual heterogeneity. Dynamic and targeted myopia prevention and control strategies should be formulated in accordance with regional demographic features and environmental changes.

Objective To investigate the impact of anesthesia and surgery on hippocampal expression of Alzheimer’s disease (AD)-associated proteins in 5×FAD transgenic mice and explore potential sex differences. Methods 5×FAD mice were crossbred with C57BL/6J wild-type (WT) mice to generate offspring for genotypic confirmation. Four-month-old 5×FAD mice and littermate (LM) WT controls were allocated into 8 experimental groups (n＝8/group): female/male 5×FAD control group, female/male 5×FAD anesthesia/surgery group, female/male LM control group, and female/male LM anesthesia/surgery group. Anesthesia/surgery groups underwent laparotomy under 1.4% isoflurane anesthesia, while control groups received no intervention. Hippocampal tissues were collected 24 hours post-procedure for Western blotting analysis of β-catenin, glycogen synthase kinase 3 beta (GSK3β), and phosphorylated GSK3β (p-GSK3β) levels. Results Female 5×FAD mice demonstrated significant reductions in β-catenin levels and p-GSK3β expression compared to both sex-matched LM controls and male 5×FAD counterparts (P＜0.05). No significant differences in these proteins were observed in male 5×FAD mice following anesthesia/surgery. Conclusions These findings reveal sex-specific responses to perioperative stress in AD, suggesting that anesthesia and surgery may affect female AD patients through hippocampal β-catenin/GSK3β pathway modulation.

Objective:To observe the clinical efficacy of acupuncture combined with Chinese medicine in the treatment of pediatric cough variant asthma(CVA)and the effects on clinical symptoms and inflammatory factor levels.Methods:A total of 136 children with CVA were randomly divided into a treatment group and a control group using the random number table method,with 68 cases in each group.Patients in the control group were treated with Chinese medicine,while patients in the treatment group were treated with Jiang Qi Ping Chuan(Qi-descending and asthma-relieving)acupuncture therapy in addition to the intervention of the control group.The clinical efficacy,cough severity,secondary symptom score,levels of inflammatory factors in induced sputum,and adverse reactions were observed after 4 weeks of treatment.Results:The total effective rate of the treatment group was higher than that of the control group,and the difference was statistically significant(P<0.05).The daytime cough score,nighttime cough score,and total cough score decreased significantly after treatment in both groups(P<0.05),and were notably lower in the treatment group than in the control group(P<0.05);the secondary symptom score and induced sputum inflammatory factor levels[interleukin(IL)-5,nerve growth factor(NGF),and substance P(SP)]decreased significantly after treatment in both groups(P<0.05),and were notably lower in the treatment group than in the control group(P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusion:The efficacy of acupuncture combined with Chinese medicine in the treatment of pediatric CVA is better than that of Chinese medicine alone;this combined method can rapidly relieve clinical symptoms and effectively inhibit inflammatory responses,with high safety.

BACKGROUND:Research has shown that endoplasmic reticulum stress-induced autophagy of neurons in the ischemic penumbra is a key link in cerebral ischemia-reperfusion injury.Autophagy mediated by the dissociation and activation of endoplasmic reticulum transmembrane proteins PERK,IRE1 α,ATF6,and GRP78/BIP plays an important role in neuronal outcomes.Traditional Chinese medicine can regulate endoplasmic reticulum stress-autophagy,reduce neuronal damage or death,and exert neuroprotective effects.OBJECTIVE:To explore the role of endoplasmic reticulum stress-autophagy in cerebral ischemia-reperfusion injury and the research progress in the regulatory mechanisms of traditional Chinese medicine.METHODS:A literature retrieval was conducted in CNKI and PubMed for relevant literature related to endoplasmic reticulum stress,autophagy,cerebral ischemia-reperfusion injury,and regulation by traditional Chinese Medicine published from January 2015 to May 2024.The search terms were"cerebral ischemia-reperfusion injury,ischemic stroke,brain injury,endoplasmic reticulum stress,autophagy,traditional Chinese medicine,compounds,signaling pathways,saponins,polyphenols,alkaloids"in Chinese and English,respectively.Any literature that is inconsistent with the research content,outdated,or duplicated was excluded.A total of 1197 relevant literature were retrieved,and 71 articles were ultimately included.RESULTS AND CONCLUSION:(1)Numerous studies have suggested that endoplasmic reticulum stress-autophagy is closely related with cerebral ischemia-reperfusion injury.(2)The active ingredients and compound formulas of traditional Chinese medicine monomers can regulate the expression of endoplasmic reticulum stress-autophagy related proteins,alleviate neuronal damage,and exert neuroprotective effects by regulating signal pathways such as PERK-eIF2α-ATF4,IRE1α-ASK1-JNK,and IRE1α-XBP.

Migraine is a common neurological disorder with a complex pathogenesis that is currently not fully understood;however,the role of mitochondrial function in migraine pathogenesis has recently attracted widespread attention.This review considers the latest research progress on the relationship between mitochondrial dysfunction and migraine,including mitochondrial energy metabolism,oxidative stress,calcium homeostasis,and neuroinflammation.We introduce the epidemiological and clinical characteristics of migraine,and provide a detailed exploration of the key role of mitochondria in these processes.Mitochondrial dysfunction may lead to increased neuronal excitability,abnormal vasoconstriction,and inflammatory responses,thereby inducing migraine.Based on the evidence of mitochondrial involvement in the pathogenesis of migraine,we propose future research directions and potential treatment strategies,with the aim of providing new ideas for the prevention and treatment of migraine.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).
