General anesthesia, pivotal for surgical procedures, requires precise depth monitoring to mitigate risks ranging from intraoperative awareness to postoperative cognitive impairments. Traditional assessment methods, relying on physiological indicators or behavioral responses, fall short of accurately capturing the nuanced states of unconsciousness. This study introduces a machine learning-based approach to decode anesthesia depth, leveraging EEG data across different anesthesia states induced by propofol and esketamine in rats. Our findings demonstrate the model's robust predictive accuracy, underscored by a novel intra-subject dataset partitioning and a 5-fold cross-validation method. The research diverges from conventional monitoring by utilizing anesthetic infusion rates as objective indicators of anesthesia states, highlighting distinct EEG patterns and enhancing prediction accuracy. Moreover, the model's ability to generalize across individuals suggests its potential for broad clinical application, distinguishing between anesthetic agents and their depths. Despite relying on rat EEG data, which poses questions about real-world applicability, our approach marks a significant advance in anesthesia monitoring.

Objective:To investigate the effect of riboflavin on cerebral infarction volume and the possible mecha-nism of apoptotic factors with cerebral ischemic injury in mice.Methods:Eighteen C57BL/6J male mice were divided into the sham group,middle cerebral artery occlusion(MCAO)group and riboflavin intervention group(MCAO+RF)randomly.TTC staining was used to observe the infarction of the cerebral tissues;Quantitative real-time PCR(RT-qPCR)was used to detect the mRNA expression of tumor protein p53(p53),cytochrome C(CytC),B-cell lymphoma-2(Bcl-2),Bcl-2-associated X(Bax),cysteinyl aspartate specific proteinase-3(caspase-3),poly ADP-ribose poly-merase(PARP),cysteinyl aspartate specific proteinase-6(caspase-6)and apoptosis inducing factor(AIF)in different groups,to study the possible mechanism of riboflavin inhibiting neuronal apoptosis.The proteins expression of acetyl-p53(AC-p53),caspase-3 and PARP were analyzed by Western blot.Results:Compared with the MCAO group,the cerebral infarct volume of the MCAO+RF group was obviously reduced(P＜0.01);The relative expression of p53,CytC,caspase-3,PARP,caspase-6 and AIF were significantly lower in the MCAO+RF group(P＜0.05).Addition-ally,significant differences were observed in the proteins expression of AC-p53,caspase-3 and PARP between the MCAO group and MCAO+RF group.Conclusion:Riboflavin has a protective effect against cerebral ischemic injury,which is possibly realized by inhibiting neuronal apoptosis through multiple pathways.

Objective To examine the molecular mechanisms of action of miR-92a-3p in ischemic stroke(IS).Methods Database analysis was performed to evaluate miR-92a-3p expression in patients with IS.Oxygen-glucose deprivation/reoxygenation(OGD/R)of HT22 hippocampal neurons was used as an in vitro IS model.PCR was performed to analyze miR-92a-3p expression in HT22 cells fol-lowing 2,4,6,and 8 h of OGD/R.Western blotting was used to analyze the protein expression levels of silent information regulator 1(SIRT1),an miR-92a-3p target gene,and the apoptosis-related protein caspase-3 in HT22 cells after 4 h of OGD/R.Middle cerebral artery occlusion(MCAO)was used as an animal model of IS.Western blotting and PCR were used to analyze the mRNA and protein expression levels of SIRT1 and caspase-3 in the brain tissues of mice following MCAO.Results Database analysis showed increased miR-92a-3p expression in fetal rat cortical neurons after 12 h of OGD and in the brain tissues of mice 3 days post-MCAO.Following 2,4,6,and 8 h of OGD/R in HT22 cells,the expression of miR-92a-3p increased,accompanied by decreased expression of SIRT1 and increased expres-sion of caspase-3.In the brain tissues of mice model of IS,SIRT1 expression decreased and caspase-3 expression increased.Conclusion miR-92a-3p is involved in IS by promoting neuronal apoptosis via SIRT1 inhibition.

Objective To analyze the clinical efficacy of"Siming Acupoint"massage technique in the treatment of true myopia in children and adolescents,and explore the related factors influencing the therapeutic effect.Methods From January 2021 to January 2024,257 cases of children and adolescents with true myopia and 475 eyes treated and followed up at the Pediatric Massage Center of Shandong Hospital of Traditional Chinese Medicine were included in this study.And they were divided into the low myopia group(374 eyes),the moderate myopia group(76 eyes)and the high myopia group(25 eyes).The clinical efficacy was analyzed by comparing the observation indicators changes before and after the intervention.The occurrence of ineffective treatment was observed,and the related factors of ineffective treatment were explored by using univariate comparison and multivariate Logistic regression analysis.Results Clinical results showed that the effective rate of 257 children and 475 eyes was 93.05%;the effective rate of 374 eyes in the low myopia group was 98.13%;the effective rate of 76 eyes in the moderate myopia group was 81.58%;the effective rate of 25 eyes in the high myopia group was 52.00%.The score of visual fatigue symptoms after the intervention was significantly lower than that before the intervention(P<0.001);The naked eye vision after the intervention was significantly higher than that before the intervention(P<0.001);After the intervention,NRA and PRA were significantly enhanced compared with those before the intervention(P all<0.001).Risk factor analysis of ineffectiveness showed that there were 33 eyes in the ineffective group and 442 eyes in the effective group.The proportion of patients with a history of sweet tooth in the ineffective group was significantly higher than that in the effective group(P=0.020);The course of disease in the ineffective group was significantly longer than that in the effective group(P=0.001);And there were also significant differences in the degree of myopia between the two groups,the proportion of high myopia in the ineffective group was significantly higher than that in the effective group(P<0.001);The spherical diopter,equivalent spherical diopter and cylindrical diopter in the ineffective group were all significantly higher than those in the effective group(P all<0.001);The axial length of the eye in the ineffective group was significantly longer than that in the effective group(P=0.005);The naked eye vision before treatment and the corrected naked eye vision at the first treatment in the ineffective group were both worse than those in the effective group(both P<0.001);The proportion of patients with outdoor activities<2 hours/day and the proportion of patients with night sleep time<7 hours/day in the ineffective group were significantly higher than those in the effective group(P=0.022,P=0.012).Binary multivariate Logistic regression analysis showed that combined outdoor activities<2 hours/day(OR=8.270,P<0.001),equivalent spherical diopter(OR=2.724,P=0.005),and night sleep time<7 hours/day(OR=2.507,P=0.014)were the risk factors for ineffective treatment of true myopia in children and adolescents with"Siming Acupoints"massage technique.The ROC curve showed that the area under the curve for outdoor activities<2 hours/day was 0.603;The area under the curve for equivalent spherical diopter was 0.678;the area under the curve for night sleep time<7 hours/day was 0.667.Conclusion The"Siming Acupoints"massage technique may be able to improve the naked eye vision of patients,improve NRA,PRA and visual fatigue symptoms,and control the growth of axial length and equivalent spherical diopter.Outdoor activities<2 hours/day,equivalent spherical diopter,and night sleep time<7 hours/day are the risk factors for ineffective treatment of true myopia in children and adolescents with"Siming Point"massage technique.

Background/Aims: Alcohol represents a leading burden of disease worldwide, including alcohol use disorder (AUD) and alcohol-related liver disease (ALD). We aim to assess the global burden of AUD, ALD, and alcohol-attributable primary liver cancer between 2000–2021. Methods: We registered the global and regional trends of AUD, ALD, and alcohol-related liver cancer using data from the Global Burden of Disease 2021 Study, the largest and most up-to-date global epidemiology database. We estimated the annual percent change (APC) and its 95% confidence interval (CI) to assess changes in age-standardized rates over time. Results: In 2021, there were 111.12 million cases of AUD, 3.02 million cases of ALD, and 132,030 cases of alcohol-attributable primary liver cancer. Between 2000 and 2021, there was a 14.66% increase in AUD, a 38.68% increase in ALD, and a 94.12% increase in alcohol-attributable primary liver cancer prevalence. While the age-standardized prevalence rate for liver cancer from alcohol increased (APC 0.59%; 95% confidence interval [CI] 0.52 to 0.67%) over these years, it decreased for ALD (APC –0.71%; 95% CI –0.75 to –0.67%) and AUD (APC –0.90%; 95% CI –0.94 to –0.86%). There was significant variation by region, socioeconomic development level, and sex. During the last years (2019–2021), the prevalence, incidence, and death of ALD increased to a greater extent in females. Conclusions Given the high burden of AUD, ALD, and alcohol-attributable primary liver cancer, urgent measures are needed to prevent them at both global and national levels.
