To investigate the distribution and biological characteristics of Trueperella pyogenes in caprine mastitis,67 milk samples from were collected from goats with mastitis in 9 dairy goat farms in the Guanzhong area of Shaanxi Province.A total of 21 strains of T.pyogenes were isolated through bacterial separation and culture.PCR amplification was conducted for 8 virulence genes of the 21 isolated strains,and the susceptibility of the strains to 10 antimicrobial drugs was tested u-sing the micro broth dilution method.Nine selected strains were subjected to genomic sequencing using Illumina Nova Seq 6000 next-generation sequencing technology,and their pathogenicity was verified by inoculating mice through the teat canal.The results of virulence gene detection showed that the positive rates of plo,cbpA,nanH,nanP,fimA,fimC-,and fimE genes among the 21 iso-lated strains were 100.0％,38.1％,52.6％,31.6％,61.9％,57.1％,and 52.4％,respectively.In con-trast,the fimG gene was not detected,which was consistent with the results of genomic compari-son by next-generation sequencing.The drug susceptibility test results showed that the susceptibil-ity rates of the isolated strains to clindamycin(CLI),ceftiofur(CEF),and vancomycin(VAN)were 100.0％,while the resistance rates to penicillin(PEN),erythromycin(ERY),sulfamethox-azole-trimethoprim(SXT),florfenicol(FFC),tetracycline(TE),gentamicin(GEN),and enroflox-acin(ENR)were 76.2％,52.1％,52.4％,52.4％,47.6％,42.9％,and 33.3％,respectively.The pro-portion of strains resistant to at least three antimicrobial drugs was 71.4％(15/21).ResFinder a-nalysis of the resistant genes identified 8 types of resistance genes in the genomes of the 9 strains,including ant(2")-Ia and ant(3")-Ia mediating aminoglycoside resistance,cmlA1 and cmx media-ting chloramphenicol resistance,erm(X)and lnu(A)mediating macrolide resistance,sul1 media-ting sulfonamide resistance,and tet(W)mediating tetracycline resistance.Except for tet(W),cm-lA,and erm(X),the other resistance genes were detected for the first time in T.pyogenes in Chi-na.In animal pathogenicity tests,mice inoculated with the isolated strains showed signs of mastitis such as redness,congestion,and inflammatory cell infiltration in the glandular tissue within 24 h,indicating that the isolated strains have pathogenicity to mouse mammary tissue.This study pro-vides preliminary insights into the biological characteristics and pathogenicity of T.pyogenes from caprine mastitis,enriching the data on its drug resistance and genomics,and offering reference and guidance for the prevention and treatment of T.pyogenes infections in large-scale dairy goat farm-ing.

BackgroundThe adolescent mood disorders become more prevalent， imposing progressively greater perceived and actual caregiving burdens on caregivers， while the current health education resources， delivery formats and training programs remain insufficient in addressing their needs. ObjectiveTo evaluate the effect of structured health education on the caregiver burden associated with adolescent mood disorders， thereby informing evidence-based strategies for alleviating the burden. MethodsA total of 195 caregivers of adolescent inpatients with mood disorders admitted to a tertiary general hospital in Mianyang from June 1， 2020 to July 31， 2022 were consecutively enrolled and randomly assigned to either the research group （n=99） or the control group （n=96） using random number table method. Both groups received routine health education. In addition， the research group participated in a structured health education program comprising three modules covering disease knowledge， medication management， coping with family stress， and guidance for daily living. Upon admission， baseline information regarding both caregivers and adolescent inpatients was collected though a self-administered questionnaire. Caregiver Strain Index （CSI） was administered to assess caregiver burden at admission， discharge， and 1， 3 and 6 months post-discharge. A self-designed health education feedback questionnaire was administered on the day of discharge to evaluate caregivers' feedback on the health education. At 6 months post-discharge， data on any hospital readmission were collected. ResultsUltimately， 85 caregivers （85.86%） in the research group and 84 caregivers （87.50%） in the control group completed the study. Generalized estimating equation analysis revealed significant time effects and group-by-time interaction effects on CSI scores between the two groups （Wald χ²=790.347， 10.047， P<0.05 or 0.01）. There was no statistically significant difference between the two groups in terms of access to disease information， trust preference and core information needs （P>0.05）. Additionally， caregivers in the research group reported significantly better understanding of the disease-related knowledge and higher ratings on the effectiveness of health education when compared to the control group， with statistically significant differences （P<0.01）. ConclusionIn contrast to routine health education， structured health education may help alleviate caregiving burden among caregivers of adolescents with mood disorders.［Funded by Sichuan Medical Association Project （number， Q190004）］

Objective To predict the potential distribution area of Halenia elliptica under current and future climate conditions;To provide a foundation for the sustainable utilization and cultivation of H.elliptica resources.Methods Based on 116 occurrence records and 36 environmental variables,this study employed correlation analysis and contribution rates to identify 10 key environmental factors of H.elliptica.The MaxEnt model,combined with Geographic Information Systems(GIS),was used to predict the potential suitable areas for H.elliptica under current and different future climate scenarios,and centroid shift analysis was performed using SDM_toolbox.Results The MaxEnt model predicted accurately,with an area under the receiver operating characteristic(ROC)curve of 0.968.Altitude,annual precipitation and mean temperature of the coldest season were identified as the primary influencing factors.The current suitable area for H.elliptica was approximately 176.04×104 km2.In the future climate conditions,the suitable habitat of H.elliptica will be moderately adjusted,especially in Sichuan and Xizang.Conclusion In the future,the suitable potential distribution areas for H.elliptica in China will increase,and there will be slight differences in the increment of different suitable potential distribution areas.This study can provide a basis for resource conservation and sustainable utilization,and highlight the importance of dynamic ecological monitoring in the context of global warming.

Objective:To explore the anger emotional state,traits and expression characteristics in patients with schizophrenia with violent behavior in community.Methods:Twenty-five patients with schizopnrenia with a history of violent behavior among the community rehabilitation institutions were selected as the violent behavior group,and 74 patients with schizopnrenia without a history of violent behavior were selected as the nonviolent behavior group.The Brief Psychiatric Rating Scale(BPRS)was used to assess psychiatric symptoms,and the State-Trait An-ger Expression Inventory(STAXI)was used to assess anger characteristics.Results:Compared with the nonviolent behavior group,the violent behavior group had significantly higher scores in the trait of anger(patient dimension score,rational dimension score)and expression of anger(total score,restraint dimension score)[(28.0±23.8)vs.(19.6±13.3),(55.0±30.6)vs.(40.0±21.5),(34.2±11.6)vs.(27.3±10.7),(56.0±26.1)vs.(33.7±21.1),Ps＜0.05].Higher scores of rationality dimension of anger trait(OR=3.69,95％CI:1.43-7.98)and re-straint dimension of anger expression(OR=3.25,95％CI:1.39-7.47)were risk factors for violent behaviors.Conclusion:Compared with patients with schizopnrenia without violent behavior,patients with violent behavior history may show more lack of rationality,and poorer anger restraint.

Objective To investigate correlation between serum bilirubin levels of different subtypes and diabetic nephropathy(DN)in patients with type 2 diabetes mellitus(T2DM).Methods Clinical data of 494 patients with T2DM admitted to Suizhou Central Hospital Affiliated to Hubei Medical University from January 2019 to May 2023 were retrospectively analyzed,and they were divided into DN group(175 cases)and non-DN group(319 cases)according to whether they had DN.Correlation between levels of total bilirubin(TBil),direct bilirubin(DBil),indirect bilirubin(IBil)in serum and the occurrence of DN were analyzed.Results There were statistically significant differences on age,course of diabetes,hypertension,coronary heart disease,smoking,drinking,TBil,DBil,IBil,alanine aminotransferase(ALT),blood urea nitrogen(BUN),serum creatinine(SCr),uric acid(UA),total cholesterol(TC),triglyceride(TG),low density lipoprotein(LDL),high density lipoprotein(HDL),glycosylated hemoglobin(HbA1c),body mass index(BMI),systolic blood pressure,fasting plasma glucose(FPG)and estimated glomerular filtration rate between two groups.Age,course of diabetes,hypertension,coronary heart disease,TBil,DBil,IBil,ALT,BUN,SCr,UA,TC,TG,HDL,LDL,HbA1c,BMI and FPG were influencing factors of DN in female T2DM patients(P<0.05).Age,course of diabetes,hypertension,coronary heart disease,smoking,alcohol consumption,TBil,DBil,IBil,ALT,BUN,SCr,UA,TC,TG,HDL,LDL,HbA1c,BMI and FPG were influencing factors of DN in male T2DM patients(P<0.05).TBil,DBil and IBil were significantly correlated with development of DN in patients with T2DM(P<0.001).Risk of developing DN gradually decreased with increasied TBil(1-15 μmol/L),IBil(1-10 μmol/L)and DBil(1-4 μmol/L),but after TBil>15 μmol/L,IBil>10 μmol/L and DBil>4 μmol/L,increased in TBil,DBil and IBil levels no longer reduced risk of developing DN.Conclusion There is a non-linear correlation between levels of TBil,DBil,IBil and risk of DN in patients with T2DM.Within a certain range,TBil,DBil and IBil are independent protective factors for occurrence of DN,and reaching a certain level will no longer reduce risk of DN.There is no significant difference between serum bilirubin and risk of DN in different genders.
