Objective:To investigate the clinical characteristics and genetic etiology of fetal Dandy-Walker spectrum (DWS) anomalies.Methods:This retrospective cohort study analyzed 28 fetuses with ultrasonographically confirmed DWS (ten classic Dandy-Walker malformations and 18 Dandy-Walker variants) at the First Affiliated Hospital, Zhengzhou University from January 2019 to June 2024. All cases underwent systematic ultrasonographic evaluation. Genetic analyses included chromosomal karyotyping alone ( n=4) or combined with copy number variation sequencing (CNV-seq) ( n=10). Descriptive statistics and Chi-square tests (or Fisher's exact test) with Bonferroni correction were applied. Results:(1) Among 28 fetuses, seven (25.0%) had isolated DWS and 21 (75.0%) non-isolated DWS. Central nervous system anomalies were most common (53.6%, 15/28). (2) Karyotyping identified abnormalities in four cases (4/14), including two triploidies, one case of mosaicism for a derivative chromosome der(1;10), and one 17p deletion. CNV-seq detected anomalies in six cases (25.0%, 6/24), four of which were missed by karyotyping: 3q23 deletion (encompassing ZIC1/ ZIC4), 13q11 duplication, and other critical variants. (3) Combined testing yielded a higher detection rate (28.6%, 8/28) than karyotyping alone (4/14, χ2=4.62, P=0.032) or CNV-seq alone (25.0%, 6/24, χ2=4.83, P=0.028) ( P=0.048 and 0.044 after Bonferroni correction). Conclusions:DWS demonstrates significant genetic heterogeneity, primarily involving chromosomal numerical anomalies (e.g., triploidy) and copy number variations (e.g., 3q23 deletion). Combined karyotyping and CNV-seq improves detection rates of genetic abnormalities.

Objective To evaluate the feasibility of emergency percutaneous coronary intervention(PCI)with extracorporeal membrane oxygenation(ECMO)support in critically ill patients with acute myocardial infarction(AMI)and cardiogenic shock(CS).Methods Retrospective analysis of clinical data of AMI combined with CS patients admitted to the department of emergency of the Second Hospital of Hebei Medical University from December 2018 to December 2021,including gender,age,body mass index(BMI),past history(smoking,coronary heart disease,arrhythmia,diabetes,hypertension,hyperlipidemia,cerebrovascular disease);acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score,highest vasoactive-inotropic score(VIS)within 24 hours of admission,the worst auxiliary examination values within 24 hours after admission:blood lactic acid(Lac),arterial partial pressure of oxygen(PaO2),cardiac troponin I(cTnI),alanine aminotransferase(ALT),total bilirubin(TBil),creatinine(Cr),serum potassium,left ventricular end-diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF)],presence of malignant arrhythmia or cardiac arrest during emergency PCI,completion of PCI,and the 30-day prognosis,etc.Patients were divided into an ECMO group and a non-ECMO group based on whether ECMO was applied,to analyze differences in the above indicators between the two groups.Results There were no statistically significant differences between the ECMO group and the non-ECMO group in terms of gender,age,BMI,past history,APACHEⅡ,VIS and the worst auxiliary examination value within 24 hours after admission.The incidence of malignant arrhythmia or cardiac arrest events and 30-day mortality rate during emergency PCI in the ECMO group were significantly lower than those in the non-ECMO group[the incidence of malignant arrhythmia or cardiac arrest during emergency PCI was 17.9％(7/39)vs.45.0％(9/20),and the 30-day mortality was 46.2％(18/39)vs.75.0％(15/20),both P<0.05].The completion rate of PCI in the ECMO group was significantly higher than that in the non-ECMO group[100.0％(39/39)vs.80.0％(16/20),P<0.05].Conclusions For critically ill patients with AMI combined with CS,ECMO support can reduce the risk of malignant arrhythmia or cardiac arrest during emergency PCI,increase the completion rate of PCI,and reduce the 30-day mortality.With the support of the ECMO team,ECMO support emergency PCI is feasible.

Compared with simple stress urinary incontinence (SUI), complicated female SUI is more diverse in etiology and more difficult to treat.Based on domestic and foreign literature and our diagnosis and treatment experience, this paper makes a detailed introduction to the definition, diagnosis, evaluation and clinical treatment of complicated female SUI, so as to provide guidance and reference for the treatment of this disease.

Objective The amplitude of low-frequency fluctuation(ALFF)resting state functional magnetic resonance imaging(rs-fMRI)was used to investigate the signals image in the brain functional areas of overactive bladder(OAB)patients.Methods OAB patients treated in 3 participating hospitals during Mar.2021 and Mar.2023 were selected as the OAB group(n=14).Healthy subjects matching the gender,age and years of education of the patients in the OAB group were collected as the control group(NC group,n=14).Changes in the over active bladder symptom score(OABSS),quality of life scale(QoL),self-rating depression scale(SDS),self-rating anxiety scale(SAS)were analyzed.All subjects underwent rs-fMRI to collect blood oxygen level dependent magnetic resonance signals,which were then processed with ALFF.Two-sample t-test was conducted on the results to obtain the different brain regions.Results The OABSS[(8.07±0.37)vs.(1.21±0.18)],QoL[(4.85±0.21)vs.(0.64±0.13)],SAS[(60.14±1.40)vs.(37.64±1.57)]and SDS[(52.50±1.29)vs.(36.14±0.34)]scores of the OAB group were higher than those of the NC group,with significant differences(P＜0.05).The brain regions with significant differences in ALFF were located in the left supplementary motor area,left medial superior frontal gyrus and right anterior central gyrus(P＜0.000 1).Conclusion The abnormal spontaneous activity and coordination ability of the brain in resting state may lead to OAB symptoms,which are displayed in the abnormal functions of the left supplementary motor area,left medial superior frontal gyrus and right anterior central gyrus.

Diabetic cardiomyopathy refers to dysfunction of cardiac muscle in patients with diabetes that cannot be directly ascribed to hypertension， coronary heart disease or other defined cardiac abnormalities. Imbalance in metabolic flexibility is the underlying cause of diabetic cardiomyopathy， which is manifested as distorted nutrient sensing， slow substrate switching， and impaired energy homeostasis. In the case of diabetes/insulin resistance， cardiac fatty acid oxidation increases while glucose oxidation decreases， resulting in the imbalance in cardiac metabolic flexibility. Thus， the heart fails to switch substrates depending on the changes （taking food/fasting， rest/exercise） and the energy production in cardiomyocytes reduced， causing cardiac dysfunction. Moreover， the excessive cardiac fatty acid fails to be degraded by the mitochondrial β oxidation， triggering cardiac lipid accumulation and reduction in glucose oxidation. Therefore， the glucose in the pentose phosphate （PPP） and the hexosamine biosynthetic pathway （HBP） increases and the production of advanced glycation end products rises， inducing glycolipotoxicity. The intermediates of abnormal substrate metabolism cause oxidative stress， inflammation， mitochondrial dysfunction and further result in impaired myocardial function. Qi and blood are the main functional substances for the normal functioning of the body. Qi and blood harmonize and work together to defend against external pathogen， while disharmony of blood and Qi will induce the production of various pathological products that lead to the occurrence of diseases. The function and regulation of Qi-Blood movement are similar to those of metabolism. Qi deficiency and blood stasis， Qi stagnation and blood stasis， and other "blood-Qi disharmony" types run through the whole process of diabetic cardiomyopathy， and "blood-Qi disharmony" will affect systemic substrate metabolism and lead to impaired energy metabolism. By systematically explaining the relationship between "blood-Qi disharmony" and "metabolic flexibility" in diabetic cardiomyopathy， we provide scientific research and clinical formulation ideas for targeting "metabolic flexibility" in the prevention of diabetic cardiomyopathy with Qi-replenishing and Blood-activating medicinals.

Objective To analyze the prognosis and influencing factors of patients with acute myocardial infarction(AMI)complicated with cardiogenic shock(CS)under extracorporeal membrane oxygenation(ECMO)support.Methods Retrospective analysis of the clinical data of ECMO supported coronary angiography and percutaneous coronary intervention(PCI)treatment for AMI complicated with CS patients who visited the department of emergency medicine of the Second Hospital of Hebei Medical University from December 2018 to December 2021,including gender,age,body mass index(BMI),past history(smoking history,coronary heart disease,diabetes,hypertension,hyperlipidemia,cerebrovascular disease),acute physiological and chronic health evaluationⅡ(APACHEⅡ),vasoactive-inotropic score(VIS),the worst auxiliary examination indicators within 24 hours before ECMO[arterial lactate acid,white blood cell count(WBC),cardiac troponin I(cTnI),alanine transferase(ALT),total bilirubin(TBil),creatinine(Cr),serum potassium(K+),left ventricular ejection fraction(LVEF)],time from onset to PCI,coronary angiography results(involved anterior descending branch,circumflex branch,right coronary artery,three-vessel lesions,left main artery lesions),whether to use intra aortic-balloon counterpulsation(IABP)and continuous renal replacement therapy(CRRT).Patients were divided into survival and death groups based on the prognosis after 30 days of onset.Univariate analysis was used to compare the differences in the above indicators between the two groups with different prognoses,Logistic regression analysis was used to analyze the independent risk factors affecting the prognosis of AMI patients with CS under ECMO support coronary angiography and PCI treatment,and the receiver operator characteristic curve(ROC curve)was drawn to evaluate the predictive value of risk factors on patient prognosis.Results Out of 39 patients,21 cases(53.8%)survived and 18 cases(46.2%)died.Compared with the survival group,the VIS score,lactate acid,time from onset to PCI,involvement of the circumflex artery,three-vessel disease,and left main artery lesions significantly increased in the death group(all P＜0.05).Logistic regression analysis showed that lactate acid and three-vessel lesions were independent risk factors affecting the 30-day prognosis of AMI patients with CS[odds ratio(OR)and 95%confidence interval(95%CI)were 1.845(1.018-3.342)and 107.171(1.307-8 785.901),all P＜0.05].ROC curve analysis showed that lactate acid and three-vessel lesions has predictive value for the prognosis of AMI combined with CS patients undergoing ECMO supported coronary angiography and PCI treatment,the area under the ROC curve(AUC)were 0.756 and 0.752,95%CI were 0.601-0.911 and 0.588-0.916,P value were 0.007 and 0.008.When the cut-off value of lactic acid was 5 mmol/L,the sensitivity and specificity of predicting the prognosis of AMI combined with CS patients undergoing coronary angiography and PCI treatment were 94.1%and 57.1%,respectively.Conclusions The indications for using ECMO in critically ill patients with AMI combined with CS need to be further refined.VIS score,lactate acid,time from onset to PCI,three-vessel lesions,and left main artery lesions are risk factors for patient death.When using ECMO support for high lactate,high VIS score,and three-vessel lesions,caution should be exercised.Early ECMO support can improve the prognosis of appropriate patients by reducing lactate,reducing the use of vasoactive drugs,and shortening the time from onset to PCI.

ObjectiveTo investigate the distribution of vascular cognitive impairment （VCI） with kidney Yang deficiency syndrome and explore the biological nature of VCI with kidney Yang deficiency syndrome from the perspective of DNA methylation under the combination of disease and syndrome， so as to provide an epigenetic target for traditional Chinese medicine （TCM） treatment of this disease with this syndrome in the future. MethodCommunity residents in Beijing were screened out for cognitive impairment from September 2020 to November 2022 through the scale， and VCI patients were analyzed for the syndrome. VCI patients with kidney Yang deficiency syndrome and healthy people were enrolled in this study. Peripheral venous blood was collected and subjected to genome-wide DNA methylation detection by Illumina Human Methylation 850K BeadChip. Then， differentially methylated genes （DMGs） were screened out for bioinformatics analysis. ResultA total of 1 902 people were investigated in this study， and 201 of them had VCI， accounting for 10.57%， including 72.14% with kidney Yang deficiency syndrome. The methylation results showed that compared with the normal group， the VCI group had 386 differential methylation sites， and 136 DMGs were annotated. The Kyoto Encyclopedia of Gene and Genomes（KEGG） signaling pathway enrichment analysis showed that the DMGs between the two groups were mainly involved in mammalian target of rapamycin（mTOR） signaling pathway， Estrogen signaling pathway， cyclic adenosine monophosphate（cAMP） signaling pathway， etc. Protein-protein interaction （PPI） analysis showed that DMGs， such as epidermal growth factor receptor（EGFR）， epidermal growth factor （EGF）， and signal transducer and activator of transcription 3（STAT3）， played important roles in the network. ConclusionKidney Yang deficiency is the main syndrome in VCI patients. DMGs including EGFR， EGF， and STAT3 and the related pathways such as mTOR signaling pathway， Estrogen signaling pathway， and cAMP signaling pathway may play a vital role in the occurrence and development of VCI with kidney Yang deficiency syndrome.

Objective: To explore the consumption of sugar sweetened beverages (SSBs) and its association with behavioral problems in Chinese preschool children, and to provide a scientific basis for the prevention of behavioral problems of children. Methods: A total of 7 634 children aged 3-6 years were chosen from kindergartens in 3 cities (Yangzhou, Xuzhou, Zhenjiang) in the lower reaches of Yangtze River using method of cluster sampling during October to November in 2017. Parental or guardian questionnaires were used to obtain information regarding child consumption of SSBs. The Strengths and Difficulties Questionnaire (SDQ) was used to assess children s emotional and behavioral problems. Multivariate Logistic regression model was used to explore the association between different SSBs intake frequency and children s behavioral problems. Results: A total of 5 509(72.2%) consumed SSBs less than once a day, 830(10.9%) reported SSBs consumption once a day, and 1 295(16.9%) had 2 times or more intake of sugar sweetened beverages per day. After adjusting for confounding factors including age, sex, BMI, family financial status, parental education, screen time, sleep duration, and physical activities duration, multiple Logistic regression model revealed that intake of SSBs once a day was associated with an increased risk of hyperactivity disorder ( OR =1.26, 95% CI =1.01-1.57) and SDQ total difficulties ( OR =1.44, 95% CI =1.14-1.82) in boys and with an increased risk of emotional symptoms ( OR=1.34, 95%CI =1.02-1.76), conduct problems ( OR=1.53, 95%CI =1.18-2.00), hyperactivity disorder ( OR=1.79, 95%CI =1.42-2.27) and prosocial behavior ( OR=1.48, 95%CI =1.14-1.91) in girls. Intake of SSBs≥2 times per day was associated with an increased risk of emotional symptoms ( OR=1.28, 95%CI =1.02-1.59) and SDQ difficulties ( OR=1.30, 95%CI =1.07-1.58) in boys and not with behavioral problems in girls. Conclusion Sex differences are observed with respect to the association between SSBs intake and behavioral problems in preschoolers, but no significant dose response relationship was observed. More longitudinal studies are needed to further explore the association between SSBs intake and behavioral problems in preschool children as well as the underlying physiological mechanisms in future.

Objective: Based on observational, longitudinal and intervention study of common diseases among students in Jiangsu Province, this paper presents the current progress of two year follow up of myopia cohort regarding the association between growth parameters with progression of myopia among children and adolescents in areas with rapid economic growth. Methods: This survey adopted the stratified cluster sampling method for school selection. The full automatic computer optometry (TOPCON RM800) was used to track myopia related parameters for all participants from 2019 to 2020 under the condition of mydriasis (compound topicamide eye drops). Relationship between growth parameters of children and adolescents and the incidence and progression of myopia was analyzed by using Cox regression multiple statistical model. Results: The myopia rates of students from grade 1 to grade 3 in 2019 were 5.4%, 21.5% and 37.3% respectively. After one year, the myopia rates of all school stages increased to 25.3%, 43.3% and 58.1% respectively( χ 2=53.59, 49.63, 32.52, P <0.01). The mean diopter of right eye and left eye after mydriasis were ( 0.30± 1.24/0.39±1.26)D in 2019 and (-0.33±1.54/-0.19±1.55)D in 2020, respectively based on Cox multiple regression results, age ( HR =1.21, 95% CI =1.09-1.34), naked eye vision ( HR =0.08, 95% CI =0.07-0.11), height ( HR =0.98, 95% CI =0.97-0.99) showed a strong correlation with the incidence and progression of myopia( P <0.05). Conclusion Myopia is growing rapidly in the central region of Jiangsu Province. It is suggested that diopter, axial length, naked eye vision, age, height and other indicators should be included in the refractive archives of children and adolescents in the region.
