Myopia prevention and control holds significant importance for the cultivation of strategic talents at the national level. In recent years, myopia among Chinese students has shown a trend of increasing prevalence and earlier onset. Once myopia develops, it is difficult to reverse. Schools, as the primary setting for student learning and activities, play a crucial role in mitigating the high incidence of myopia among students. This article provides a review of the progress in school-based myopia prevention and control interventions both domestically and internationally, with a focus on visual tracking exercises, outdoor light exposure, and improvements to classroom lighting environments. The study finds that methods such as visual tracking exercises, outdoor light exposure, and classroom lighting improvement can effectively prevent students from developing myopia and control the progression of myopia. The findings may offer scientific evidence for further improving policy formulation in China.

Objective:To investigate the factors for adverse pregnancy outcomes and the value of throm-boelastography(TEG)in patients with prethrombotic state(PTS)during pregnancy.Methods:A total of 183 preg-nant women with PTS treated at the Department of Obstetrics,Xiangya Third Hospital,Central South University,from January 2020 to September 2023 were retrospectively analyzed.These women were divided into two groups based on pregnancy outcomes:the favorable pregnancy outcome group(97 cases)and the adverse pregnancy outcome group(86 cases).The risk factors for adverse pregnancy outcomes were evaluated by univariate and multivariate analyses,and the diagnostic value of TEG was assessed using the receiver operating characteristic(ROC)curve and Kaplan-Meier method.Results:The results of univariate analysis indicated that,compared to-the favorable pregnancy outcome group,the positive rates of antinuclear antibody(ANA),anticardiolipin antibody(ACA),and anti-beta2 glycoprotein antibody 1(β2-GP1)were higher in the adverse pregnancy outcome group(P<0.05),and lower utilization rates of hydroxychloroquine and low-molecular heparin(P<0.05),and shorter clotting reaction time in the thromboelastography(TEG-R)(P<0.05).Multivariate Logistic regression analyses revealed that TEG-R,ANA,β2-GP1 and gestational age at treatment initiation were all independent risk factors for adverse pregnancy outcome in pregnant women with PTS during pregnancy(P<0.05).ROC curve analysis showed the area under the curve for TEG-R was 0.632(95%Cl 0.551-0.741).At a TEG-R value of 4.65 min,the specificity was 0.948 and the sensitivity was 0.302.Kaplan-Meier survival curve analysis revealed that the gesta-tional weeks of pregnant women with an TEG-R>4.65 min were significantly longer than those with an TEG-R≤4.65 min.These results were statistically significant(P<0.01).Conclusions:ANA,ACA,β2-GP1,and TEG are valuable for predicting and evaluating adverse pregnancy outcomes in PTS patients.The TEG-R value≤4.65 min may serve as a critical threshold to guid anticoagulant therapy during pregnancy.

It is proposed that the brain Xuanfu and the glymphatic system(GS)have commonality in physiological structure and similarity in functions such as transporting brain substances,transmitting brain information and clearing metabolites.It is believed that GS may be the substantial manifestation of the brain Xuanfu,and GS dysfunction is the key pathological link of depression.Xuanfu stagnation and Shenji dysfunction are the core pathogenesis of depression.Taking"Brain Xuanfu-GS"as the starting point,the patho-logical mechanism of depression is deeply explored,providing a theoretical basis for the clinical diagnosis and treatment of depression in traditional Chinese medicine.

Objective To investigate the predictive value of matrix γ-carboxyglutamic acid protein(matrix GLA protein)expression in patients with acute myocardial infarction(AMI)for major adverse cardiovascular events(MACE)after percutaneous coronary intervention(PCI).Methods A total of 157 AMI patients undergoing PCI in our department from November 2021 to Septem-ber 2023 were recruited,and divided into a MACE group(43 cases)and a non-MACE group(114 cases)based on the occurrence of MACE over a 12-month follow-up period post-surgery.Multiva-riate logistic regression analysis was used to screen the predictors of MACE and to verify their predictive value.Results The MACE group had significantly older age,larger proportion of diabe-tes,and higher low-density lipoprotein cholesterol(LDL-C)level,but lower matrix GLA protein level than the non-MACE group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that age(OR=1.168,95％CI:1.004-1.358,P=0.044),diabetes(OR=3.085,95％CI:1.024-9.301,P=0.045)and LDL-C(OR=2.473,95％CI:1.185-5.163,P=0.016)were risk factors,and matrix GLA protein(OR=0.527,95％CI:0.426-0.653,P=0.001)was a protective factor for MACE in AMI patients after PCI.ROC curve analysis indicated that matrix GLA pro-tein had the highest predictive value of MACE in AMI patients after PCI,with an AUC value of 0.838(95％CI:0.770-0.892).After adjusting for age,diabetes,and LDL C,the restricted cubic spline revealed that matrix GLA protein level was in a nonlinear negative correlation with MACE risk(x2=30.260,P＜0.05).Conclusion Matrix GLA protein can predict the occurrence of MACE in AMI patients after PCI.

Objective To analyzing the correlation between serum microRNA(miRNA,miR)-128-3p,miRNA(miR)-126 expression and Gensini score in patients with coronary artery disease.Methods A retrospective study was conducted on 60 patients with coronary artery disease who were treated in the Department of Cardiology,Harrison International Peace Hospital from June 2020 to 2022.They were selected as the observation group,and another 60 patients with non-coronary artery disease who were treated in the hospital during the same period were selected as the control group.Serum miR-128-3p,miR-126 and Gensini scores were measured and compared between the two groups,and compared the serum miR-128-3p,miR-126 and Gensini scores of patients with single,double,and multiple vessel lesions in the observation group.According to the stenosis rate of coronary arteries,they were divided into I degree,II degree,III degree and IV degree groups.The serum miR-128-3p,miR-126 and Gensini scores were compared among different stenosis grading groups.According to the Gensini score,patients were divided into mild and severe lesion groups.According to the Gensini score,patients were divided into mild and severe lesion groups.The serum miR-128-3p and miR-126 levels were compared between the mild and severe lesion groups.Pearson analysis determined the correlation between serum miR-128-3p and miR-126 levels and Gensini score.Receiver operating characteristic curve(ROC)was plotted,and the area under curve(AUC)was calculated to analyze the predictive efficacy of the combined detection of serum miR-128-3p and miR-126 levels for coronary artery disease.Logistic regression analysis of influencing factors of coronary artery disease.Results Compared with the control group,the observation group showed an increase in serum miR-128-3p(4.28±0.52 vs 2.61±0.36)and Gensini score(31.29±5.62 score vs 6.16±1.04 score),observation group showed a decrease in serum miR-126,with statistically significant differences(t=21.678,34.058,11.002,all P<0.05).Compared with the double vessel disease and single vessel disease groups,the serum miR-128-3p and Gensini score in the multi vessel disease group increased(t=4.945,7.171;6.795,11.686),the serum miR-126 decreased(t=3.104,5.033),and the differences were statistically significant(all P<0.05).Compared with the I～II group,the serum miR-128-3p and Gensini score in the III～IV group increased significantly(t=5.590,12.961),the serum miR-126 decreased significantly(t=6.021),with statistical significance differences(all P<0.05).Compared with the mild lesion group,the serum miR-128-3p level increased in the severe lesion group(t=4.056),the serum miR-126 level decreased(t=4.806),and the differences were statistically significant differences(all P<0.05).There was a positive correlation between serum miR-128-3p and Gensini score(r=0.404,P<0.05),and a negative correlation between serum miR-126 and Gensini score(r=-0.393,P<0.05).The AUC of combined detection of serum miR-128-3p and miR-126 was higher than that of single detection,and the differences were statistically significant(Z=2.768,2.152,all P<0.05).The differences in smoking,triglycerides(TG),uric acid(UA),fibrinogen(FIB)between the observation group and the control group were statistically significant(t/χ2=4.231～28.732,all P<0.05).Conclusion Patients with coronary artery disease have high expression of serum miR-128-3p and low expression of serum miR-126,which is correlated with Gensini score.The combined detection of serum miR-128-3p and miR-126 can improve the predictive efficiency of coronary artery disease,and the occurrence of coronary artery disease is related to multiple factors,which should be given clinical attention.

Objective:To evaluate the clinical features of dystonia in patients with different types of atypical Parkinson syndrome (APS).Methods:A total of 104 patients with APS admitted in the Department of Neurology, Beijing Hospital from January 2015 to June 2023 were enrolled in the study, including 57 cases of multiple system atrophy (MSA), 38 cases of progressive supranuclear palsy (PSP) and 9 cases of corticobasal degeneration (CBD). Among 104 cases there were 63 males (60.6%), the mean age of patients was (62.3±8.9) years (54 to 73 years). The sex, age at onset, disease duration, first symptom, clinical features of dystonia and other neurological signs, response to levodopa therapy, numbers of Hoehn & Yahr scale≥3 after 3 years of disease, and MRI findings were documented in patients with different type APS.Results:The overall frequency of dystonia in this series was 45.2%(47/104), and 33.3% (19/57) for MSA group, 50.0% (19/38) for PSP group, 9/9 for CBD group. The types of dystonia were anterocollis, retrocollis, blepharospasm, oromandibular, foot/limb dystonia, Pisa syndrome and myoclonus. In all 47 cases presenting dydtonia, dystonia was not the first complaint and it did not respond to levodopa therapy.Conclusion:In this series of atypical Parkinson syndrome, dystonia is a common feature of the disease, while it is not the first symptom at disease onset, and usually does not respond to levodopa therapy.

This article reports the clinical and genetic characteristics of a female patient with X-linked sideroblastic anemia with ataxia (XLSA/A). The 36-year-old patient had an insidious onset with progressive worsening, primarily presenting with ataxia, dysarthria, and cognitive decline. Magnetic resonance imaging of the head revealed mild atrophy of the brainstem and cerebellum. Whole-genome sequencing identified a heterozygous c.871G>A (p.G291S) variant in the ABCB7 gene, inherited from the patient′s mother. X-chromosome inactivation analysis showed a skewed ratio of 82% (with predominant inactivation of the paternal X chromosome). This study is the first to report a case of XLSA/A in a female caused by a heterozygous ABCB7 gene c.871G>A variant, indicating that skewed X-chromosome inactivation can lead to clinical manifestations in female carriers, expanding the understanding of the pathogenesis of XLSA/A.

In recent years,the intensification of dairy farming has significantly improved production efficiency but has also led to a rise in the incidence of metabolic diseases.Conditions such as keto-sis,fatty liver,and hypocalcemia pose serious threats to dairy cattle health and productivity.These diseases not only profoundly affect individual physiological function but also impose considerable economic pressures and challenges on farm management.As research advances,exosomes have e-merged as a novel intercellular signaling molecule,showing unique potential in regulating dairy cattle's nutritional metabolism.Studies suggest that exosomes hold promise as biomarkers for dis-ease and can even serve as carriers for disease detection and prevention.Acting as a crucial mediator of intercellular communication,exosomes play an important role in modulating the metabolic processes of dairy cattle.This review aims to systematically explore the role of exosomes in bovine nutritional metabolism and to provide new perspectives and theoretical support for their potential as tools for diagnosing,treating,and preventing metabolic diseases in dairy cattle,thus advancing research and practice in this field.
