Journal of Apoplexy and Nervous Diseases 2026;43(3):259-264
Objective To investigate the differences in emotional processing characteristics and electroencephalography (EEG) power values in patients with Parkinson disease (PD). Methods A total of 24 PD patients were enrolled as subjects, and 30 healthy individuals were enrolled as control group. With the use of the EPIE experimental paradigm, SAM questionnaire was used to determine the scores of emotional valence and arousal, and EEG was used for real-time monitoring of cortical EEG signals. The two groups were compared in terms of the differences in valence/arousal and EEG power values under different emotions and their correlation. Results The PD group had significantly higher BAI and BDI scores than the control group[BAI(16.92±3.83)vs(11.62±3.65),t=4.521,P<0.05;BDI(22.69±2.30)vs(14.17±4.06),t=7.981,P<0.05]. In the negative mood, there were significant differences in valence/arousal between the two groups (t=4.505,-7.705,bothP<0.05). There were significant differences between the two groups in power values at Fp1,Fp2,F7,F3,F4,T3,T4, and T5(t=-4.12,-12.43,5.76,-2.90,-4.72,-5.34,-5.81,-2.65,all P<0.05). In the negative mood, for the control group, valence score was correlated with Fp1 (r=-0.837, P<0.01), Fp2 (r=-0.920, P<0.01),F4(r=-0.604,P=0.008),P3(r=-0.658,P=0.003),and P4(r=-0.546,P=0.019), and arousal score was correlated with Fp1(r=0.887, P<0.01), Fp2 (r=0.958, P=0.003),F4(r=0.683,P=0.003),P3 (r=0.721, P=0.003),and P4 (r=0.610,P=0.007); for the PD group, valence score was correlated with Fp2(r=-0.490,P=0.015) and F7(r=-0.564,P=0.004), and arousal score was correlated with Fp2 (r=0.440, P=0.031) and F7(r=0.853,P<0.01). Conclusion Patients with PD have negative emotional processing abnormalities associated with right PFC and left lateral FL.

This study investigated the potential pathogenicity and genetic characteristics of ST314 Salmonella Kentucky(S.Ken-tucky)isolates from a broiler slaughterhouse.Antimicrobial susceptibility testing and whole-genome sequencing(WGS)were used to determine antimicrobial resistance,virulence factors,and the presence of antimicrobial resistance genes(ARGs)and mobile genetic elements(MGEs)among the isolates.The three multidrug resistant(MDR)isolates exhibited high resistance to multiple antimicrobial agents.The F4-2S strain exhibited resistance to 14 drugs across seven categories,whereas the F4T strain showed resistance to 13 drugs in the same number of categories.In contrast,the Y23 strain was resistant to nine drugs in six categories.Notably,F4-2S dem-onstrated high homology with F4T:both possessed 13 ARGs distributed across nine categories,in addition to a wide range of virulence factors,including secretion systems and effector proteins.The presence of IncR and IncX1 plasmids significantly enhanced both the antimicrobial resistance and pathogenicity of the isolates.The genome map of Y23 revealed a chromosome alongside two plasmids.The chromosome containedonly one resistance gene but several virulence factors,including the type III secretion system(T3SS),which is crucial for bacterial invasion.The plasmid pY23-1 contained eight types of 19 ARGs.Comparative analysis indicated that pY23-1 ex-hibited high homology with pZ1323SSL0055 and pSAL-045,all of which contained multiple ARGs,thus suggesting critical roles of these genes in the evolution of bacterial resistance.In conclusion,ST314 S.Kentucky demonstrated a complex mechanism of resis-tance coupled with significant pathogenic potential.The ARGs and MGEs in the plasmid contributed to the emergence and dissemina-tion of antimicrobial resistance.The multiple virulence factors present in the chromosome may be key factors driving the increasing virulence of ST314 S.Kentucky.

Objective To explore the differences in the radiological features,clinical,and laboratory indicators of frequent versus infrequent gout flares in the feet and ankles using dual-energy computed tomography(DECT).Methods A retrospective selection was made on 385 gout patients,who were divided into the frequent flare group(≥2 gout attacks per year,219 cases)and the infre-quent flare group(<2 gout attacks per year,166 cases).Clinical data,laboratory indicators,and DECT imaging findings were col-lected for statistical analysis.Binary logistic regression was used to analyze the independent risk factors for frequent gout flares and receiver operating characteristic(ROC)curve was plotted.Results Statistically significant differences were found between the fre-quent flare group and the infrequent flare group in terms of disease duration,body mass index(BMI),blood pressure,triglyceride(TG),serum uric acid(SUA),monosodium urate(MSU)crystal deposition,total volume of MSU crystals,maximum diameter of individ-ual tophi,number of affected joints,bone erosion,maximum depth of bone erosion,soft tissue swelling,bone proliferation and sclero-sis,and joint space narrowing(P<0.05).SUA levels,MSU crystal deposition,total volume of MSU crystals,and maximum depth of bone erosion were identified as independent risk factors for frequent gout(P<0.05).Both the combination of four factors model and the maximum depth of bone erosion model had better diagnostic efficacy.Conclusion Gout patients with high SUA levels,MSU crystal deposition,larger total volume of MSU crystals,and greater maximum depth of bone erosion are more likely to experience frequent gout attacks.Patients with bone erosion depth>3.200 mm are more likely identified early as having frequent gout.

Objective:To investigate the mode and timing of delivery in pregnant women with complex fetal congenital heart disease (CHD) detected by prenatal ultrasound.Methods:The clinical data of 123 fetuses with complex CHD detected by prenatal ultrasound in Peking University People′s Hospital from January 2016 to December 2023 were retrospectively analyzed. Pregnant women with indications for prenatal diagnosis underwent G-banding karyotype analysis, single nucleotide polymorphism array (SNP arrry) or whole exome sequencing after informed consent. Integrated managements were provided for pregnant women with complex CHD during pregnancy and perinatal period, and to determine the mode and timing of delivery. Infants with complex CHD received timely treatment or referral after birth.Results:The gestational age at ultrasound diagnosis of the 123 fetuses with complex CHD was (23.7±3.4) weeks. There were 11 cases (8.9%) of total anomalous pulmonary venous connection (TAPVC), 14 cases (11.4%) of anomalous pulmonary valve (PVA), 7 cases (5.7%) of right ventricle double outlet (RVDO), 13 cases (10.6%) of anomalous aortic arch, 69 cases (56.1%) of transposition of the great arteries (TGA), 9 cases (7.3%) of other types. All cases were treated with fetal preservation after prenatal consultation. Among the 72 cases undergoing prenatal diagnosis, 9 cases (12.5%) had chromosomal variations. Fifty-five cases (44.7%, 55/123) underwent trial of labor, of which 46 cases (37.4%, 46/123) had successful vaginal delivery, including 6 cases of forceps delivery, and other 9 cases of failed trial of labor transferred to cesarean section. A total of 77 cases of pregnant women underwent cesarean section. Except for the 21 cases of pregnant women who asked for cesarean section, the cesarean section rate of pregnant women with complex CHD was 45.5% (56/123), which was not significantly different from the average cesarean section rate of the same period in our hospital (40.2%; χ2=7.34, P=0.270). The gestational age at delivery of the 123 fetuses with complex CHD was (37.9±1.4) weeks, the birth weight of the neonates was (3 099±480) g, and the umbilical artery blood pH value was 7.31±0.05. The oxygen saturation of 86 cases before and after alprostadil infusion were (72.8±6.0)% and (80.5±5.0)%, respectively, and the difference was statistically significant ( t=4.38, P<0.001). One hundred and fourteen children underwent surgical treatment, 112 of them (98.2%) had good postoperative reexamination. Only 2 cases (1.8%) died after surgery, and 14.0% (16/114) had the possibility of secondary surgery. Conclusions:Fetal complex CHD is not an indication for cesarean section, and the delivery mode could be selected according to the obstetric situation. If the mother and child are in stable condition, the delivery is planned after 39 weeks of gestation. For children with low oxygen saturation after birth, alprostadil could be pumped to maintain the open ductus arteriosus, and timely referral to the pediatric cardiac surgery for subsequent surgical treatment, which could achieve a good prognosis.

Aim To investigate the effects of m6A demethylase ALKBH5 on cardiomyocytes pyroptosis in mice with myocardial infarction(MI).Methods The MI model of left anterior descending coronary artery ligation surgery was established by knocking down ALKBH5 using adeno-associated virus,and the hypox-ia model of mouse cardiomyocytes(HL-1)was estab-lished by knocking down small interfering RNA.The effects of ALKBH5 on the pyroptosis of MI mice and hypoxic HL-1 cells were observed.Subsequently,mechanism studies were conducted at the cellular lev-el,and the binding of ALKBH5 and IGF2BP2 to NL-RP3 mRNA was detected through RNA pull down and RNA immunoprecipitation(RIP)experiments.The MeRIP-qPCR method was used to determine the effects of ALKBH5 on the mRNA m6A level of NLRP3.Acti-nomycin D for RNA stability experiments were conduc-ted to detect the effects of ALKBH5 and IGF2BP2 on the stability of NLRP3 mRNA.Results Knocking down ALKBH5 in vivo and in vitro both inhibited NL-RP3 inflammasome activation and alleviated pyroptosis in MI mice and hypoxic HL-1 cells.Mechanistically,the results showed that NLRP3 mRNA could bind to ALKBH5 protein in HL-1 cells;knocking down ALK-BH5 could increase the m6A level of NLRP3 and re-duce the stability of NLRP3 mRNA;subsequently,it was confirmed that NLRP3 mRNA and IGF2BP2 pro-tein bound to each other;knocking down IGF2BP2 in-creased the mRNA stability of NLRP3.The Rescue ex-periment showed that knocking down IGF2BP2 re-versed the decrease in NLRP3 mRNA expression caused by knocking down ALKBH5.Conclusions ALKBH5 mediated m6A modification of NLRP3 pro-motes cardiomyocytes pyroptosis in mice with myocardi-al infarction.

On the basis of that the fluorescence wavelength of copper nanoclusters(CuNCs)could cover the entire visible region,multicolor fluorescent CuNCs/starch composites were prepared and applied in fingermark development.With L-glutathione as the reducing agent and protective ligand,blue emissive and orange emissive CuNCs solutions were obtained in alkaline solutions at 90℃and 25℃,respectively.With the aggregation-induced emission effect induced by ethanol as a poor solvent,the fluorescence of orange emissive CuNCs with a higher intensity was achieved in an ethanol-water solution.With ascorbic acid as the reducing agent and 3-mercaptopropionic acid as the protective agent,green emissive CuNCs solution was prepared in an acid solution.Particle morphologies,chemical compositions and optical properties of these three CuNCs above were investigated using physical characterization and spectroscopic analysis,indicating that well-dispersed CuNCs had excellent photoluminescent properties.These CuNCs solutions were combined with starch to form composite powders by simply drying.The influences of the type of CuNCs and the ratio of CuNCs to starch on the emission wavelength and fluorescence intensity of the products were studied.The obtained CuNCs/starch composites could emit blue,green and orange fluorescence under 365 nm ultraviolet light,respectively,which were suitable for fingermark development.Minutiae and partial level-3 features of latent fingermarks could be effectively developed.High-quality fluorescence fingermark images would be captured using appropriate optical filters to eliminate background interference of various substrates.

Objective To retrospectively analyze the association between metabolic factors and high-risk colorectal adenoma(CRA).Methods The medical records of patients aged 18-75 years who underwent their initial colonoscopy at Karamay Central Hospital of Xinjiang Uygur Autonomous Region from Jul 2000 to Mar 2017 were collected.The comparison between normal colonoscopy(NC)and high-risk CRA patients was conducted using an unpaired t-test,while chi-square test was used for categorical variables.Least absolute shrinkage and selection operator(LASSO)regression and Logistic regression were utilized to analyze the association between metabolic factors and high-risk CRA.Results A total of 1 798 patients meeting the inclusion and exclusion criteria were enrolled and divided into normal colonoscopy(NC)findings group(n=972)and high-risk CRA group(n=826).The high-risk CRA group exhibited significantly lower levels of high-density lipoprotein cholesterol(HDL-C)in comparison to the NC group,while uric acid and fibrosis 4(FIB-4)index levels were significantly higher than those observed in the NC group(all P<0.05).Based on LASSO regression analysis,we identified 12 variables that potentially influence the occurrence of high-risk CRA,including age,gender,smoking history,alcohol consumption history,non-alcoholic fatty liver disease(NAFLD),hypertension,coronary artery disease,hyperglycemia,hypercholesterolemia,low levels of HDL-C,elevated alanine aminotransferase,and elevated gamma-glutamyl transferase.Multivariate analysis revealed that individuals aged over 50 years,male gender,cigarette and alcohol consumption,low HDL-C levels,history of NAFLD and hypertension were identified as independent risk factors associated with high-risk CRA(P<0.05).In addition,without or with adjusting for age,sex,smoking,and drinking history,patients with a high TG/HDL-C ratio(the ratio≥2.68)had a significantly higher risk of high-risk CRA than those with a low TG/HDL-C ratio(the ratio<2.68)[odds ratios(ORs)were1.430 and 1.235 respectively,all P<0.05)].Without or with adjusting variables,the ORs for NAFLD patients with FIB-4 index>2.67 were 1.849(P=0.466)and 1.435(P=0.707),respectively.Conclusion A significant association exists between metabolic factors and high-risk CRA.Independent risk factors for high-risk CRA include older age(≥50 years),male,smoking history,alcohol consumption history,low levels of HDL-C,and a history of NAFLD and hypertension.Individuals exhibiting a TG/HDL-C ratio exceeding 2.68 manifest a significantly heightened susceptibility to the development of high-risk CRA.Therefore,elderly males with one or more aforementioned metabolic abnormalities should be considered a priority population for colorectal screening.
