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.
Electroencephalography

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 investigate the effects of galectin-3(Gal3)on autophagy in high glucose-induced human telomerase reverse transcriptase-immortalized retinal pigment epithelial(hTERT-RPE)cells.Methods The hTERT-RPE cells cultured in vitro were randomly divided into a normal group(group C),a high glucose group(group HG),a high glu-cose+si-NC group(group HG+si-NC)and a high glucose+si-Gal3 group(group HG+si-Gal3).Reverse transcrip-tion polymerase chain reaction(RT-PCR)was used to detect the relative mRNA expression levels of Gal3,intercellular ad-hesion molecule(ICAM)-1,interleukin(IL)-6 and tumor necrosis factor(TNF)-α in hTERT-RPE cells of each group.The expression levels of IL-1 and IL-6 in the supernatant of hTERT-RPE cells were measured by enzyme-linked immunosorbent assay(ELISA).The expression level of reactive oxygen species(ROS),the activity of superoxide dismutase(SOD)and the content of malondialdehyde(MDA)in hTERT-RPE cells were analyzed by dichlorofluorescin diacetate(DCFH-DA)staining,the colorimetric method and the microplate method,respectively.The protein expression levels of Gal3,the ratio of microtubule associated protein 1 light chain 3(LC3)type Ⅱ to type Ⅰ(LC3 Ⅱ/LC3 Ⅰ),Beclin 1,and autophagy-associat-ed 5(ATG5)and 7(ATG7)in hTERT-RPE cells from each group were detected by Western blot analysis.After the hTERT-RPE cells in each group were transfected with double fluorescent mRFP-GFP-LC3 plasmids alone and with RFP-LAMP1 and GFP-LC3 plasmids jointly,the changes of autophagy flow in hTERT-RPE cells were detected by laser confocal microscopy.Results Compared with the group C,the group HG showed an increase in the expression of Gal3,IL-1,IL-6,TNF-α,ICAM-1,P62,ROS and MDA content(all P＜0.05).However,the expression of LC3 Ⅱ/LC3 Ⅰ,Beclin1,ATG7,ATG5,the SOD activity,and the number of red(autolysosomes)and yellow fluorescence spots(autophagosomes)of the double fluo-rescent mRFP-GFP-LC3 plasmid were all lower in the group HG than those in the group C(all P＜0.05).There was no sig-nificant difference in the number of yellow fluorescent spots(autolysosomes)co-located by RFP-LAMP1 and GFP-LC3 plas-mids between groups C and HG(P＞0.05).There were no significant differences in the expression levels of the above-mentioned indexes in hTERT-RPE cells between groups HG and HG+si-NC(all P＞0.05).The expression levels of Gal3,IL-1,IL-6,TNF-α,ICAM-1,P62,ROS and MDA content in hTERT-RPE cells of the group HG+si-Gal3 were lower than those of the group HG+si-NC(all P＜0.05).Compared with those in the group HG+si-NC,the expression levels of LC3 Ⅱ/LC3 Ⅰ,Beclin1,ATG7,ATG5,SOD activity,and the number of red and yellow fluorescent spots of the double fluo-rescent mRFP-GFP-LC3 plasmid were increased in the group HG+si-Gal3(all P＜0.05).There was no significant differ-ence in the number of yellow fluorescent spots co-located by RFP-LAMP1 and GFP-LC3 plasmids between groups HG+si-GaL3 and HG+si-NC(P＞0.05).Conclusion Gal3 is significantly elevated in hTERT-RPE cells induced by high glu-cose,resulting in impaired autophagy flow.It produces a direct regulatory effect on the formation of autophagosomes,and plays a highly active role in oxidative damage and expression of inflammatory factors in hTERT-RPE cells induced by high glucose.

Objective To compare the value of ultrashort echo time(UTE)and T1W sequences for detecting bone erosions of gouty arthritis.Methods Forty-four gouty patients were prospectively enrolled,including 32 cases with affected feet and 12 cases with affected knee.MR UTE and T1W sequence scanning of the affected area were performed,and subjectively scoring of imaging quality of 2 kinds of MRI were evaluated,respectively.Then total number and total score of bone erosions of each case were calculated according to all affected bones.Taken DECT as reference standard,the efficacy of UTE and T1WI for detecting bone erosions was assessed through comparing with DECT using Kappa coefficient.Results The imaging quality score of T1WI was lower than that of DECT(all P＜0.05),while no significant difference was found between UTE and DECT(all P＞0.05).There was high agreement between UTE and DECT for detecting bone erosions(κ=0.949),while the agreement between T1WI and DECT ranged from good to high(κ=0.718 to 0.805).The total number and total score of bone erosions based on T1WI were significantly lower than those based on DECT(all P＜0.05),while no significant difference was found between UTE and DECT(all P＞0.05).Conclusion UTE was better than T1WI for detecting bone erosions of gouty arthritis.

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.

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.

Objective:To compare the efficacy of linaclotide and procalcitide in the treatment of adult constipation IBS-C.Methods:A retrospective study was conducted on 80 IBS-C patients admitted from May 2021 to May 2024.All patients were treated with novel secretagogues,and were divided into four groups according to the different treatment methods:linarotinib group and Pucanapide group,with 40 patients in each group.The clinical efficacy of oral administration of 290 μg of Nallotide capsules and 3 mg of Pucanapeptide in the Linalotide group and Pucanapeptide group was compared after one month of continuous treatment.The scores of IBS-C symptoms related to stool frequency,stool characteristics,upper abdominal pain,early satiety,and bloating were evaluated before and Post-treatment.Enzyme linked immunosorbent assay(ELISA)was used to detect the levels of vasoactive intestinal peptide(VIP),substance P(SP),5-hydroxytryptamine(5-HT),motilin,and gastrin IBS-C related serum markers in feces.The 16s rDNA fluorescence quantitative polymerase chain reaction method was used to detect Escherichia coli and lactate in feces.Compare the incidence of adverse reactions between the two groups based on the levels of Bacillus and Bifidobacterium.Results:There was no difference in the total effective rate between linagliptin group and Pucanotide group(P＞0.05);Post-treatment,the fecal frequency scores of the linaclotide group and the procalcitonin group were higher than pretherapy,while the fecal characteristics,upper abdominal pain,early satiety,and fullness scores were lower than pretherapy(P＜0.05).There was no difference in the fecal frequency,fecal characteristics,early satiety,and fullness scores between the linaclotide group and the procalcitonin group(P＞0.05),and the upper abdominal pain score of the linaclotide group was lower than that of the procalcitonin group(P＜0.05);Post-treatment,VIP,SP,5-HT,motilin and gastrin levels in linagliptin group and Pucanotide group were all lower than that pretherapy(P＜0.05),and there was no significant difference between linagliptin group and Pucanotide group(P＞0.05);Post-treatment,the levels of Escherichia coli in the linaclotide group and the procaine group were lower than pretherapy,while the numbers of Lactobacilli and Bifidobacteria were higher than pretherapy(P＜0.05).There was no difference between the linaclotide group and the procaine group(P＞0.05);There was no difference in the incidence of headache,bloating/abdominal pain between the linaclotide group and the procaine group(P＞0.05),and the incidence of diarrhea in the procaine group was lower than that in the linaclotide group(P＜0.05).Conclusion:Linalotide and Pucanatide have similar therapeutic effects in treating adult IBS-C,both of which can improve patients' clinical symptoms,serum biomarker levels,and intestinal microbiota structure.However,Linalotide has a better effect on improving abdominal pain,while Pucanatide can reduce the risk of diarrhea.Therefore,the clinical application of different new secretagogue drugs can be determined based on individualized symptoms and diarrhea risk of patients.

Aim To investigate the promotive effects and mechanisms of the combined use of brucine(Bru)and lumbrokinase(LK),active ingredient derived from Longma formula,in promoting chondrocyte proliferation via the Wnt/β-catenin signaling pathway.Methods The extracted primary rat chondrocytes were divided in-to the following groups:Control group,Bru,LK alone group,and Bro+LK combination group.The optimal drug concentration and intervention time were deter-mined using CCK-8 assay,followed by cell proliferation validation through EdU and phalloidin staining.The expression levels of collagen Ⅱ,aggrecan and SRY-re-lated high-mobility group box gene 9(SOX9)in chon-drocytes following intervention with the combination of Bru and LK were detected by Western blotting.Addi-tionally,the regulatory effects of these proteins on the Wnt/β-catenin signaling pathway were also investiga-ted.Results The optimal combination concentration of Longma formula active ingredients(Bru 0.025 mg·L-1+LK 5 mg·L-1)significantly enhanced chondro-cyte viability compared to control,Bru,or LK alone at 48 h.This combination increased the S-phase ratio,promoted the aggregation of intracellular actin fila-ments,and upregulated the expression of collagen Ⅱ and aggrecan.Furthermore,it activated the Wnt/β-catenin pathway,leading to increased SOX9 expres-sion.Conclusions The optimal combination of Bru and LK(Bru 0.025 mg·L-1+LK 5 mg·L-1)de-rived from Longma formula significantly maintains chondrocyte phenotype and promotes cellular prolifera-tion through the activation of the Wnt/β-catenin signa-ling pathway,which subsequently upregulates the downstream target SOX9.
