Objective To explore the correlation between thyroid antibody levels and early renal injury in patients with type 2 diabetes mellitus(T2DM)combined with Hashimoto's thyroiditis(HT).Methods A total of 375 T2DM patients hospitalized in The Affiliated Hospital of Xuzhou Medical University from January 2018 to December 2022 were selectedas the study subjects,and 197 healthy people were selected as the control subjects.The patients with T2DM were divided into simple T2DM group(n=191)and T2DM combined with HT group(HT,n=184).According to the urinary albumin/creatinine ratio(UACR)level,T2DM patients with HT were divided into microalbuminuria subgroup(MUAlb,30≤UACR≤300 mg/g,n=70)and normal albuminuria subgroup(NUAlb,UACR<30 mg/g,n=114).According to whether the thyroid antibody was positive,they were divided into thyroid peroxides antibody[TPOAb(+)]subgroup(n=56),thyroglobulin antibody[TGAb(+)]subgroup(n=40)and TGAb and TPOAb double antibody positive subgroup(n=88).Results Compared with the NC group,the smoking,drinking,urinary creatinine,alpha 1-microglobulin,UACR,FPG,HbA1c,LDL-C,TC,and TG in the HT and T2DM groups increased(P<0.05),while HDL-C decreased(P<0.05).Compared with the NUAlb subgroup,the MUAlb subgroup showed age,DM duration,FPG,HbA1c,TGAb,TPOAb,thyroid stimulating hormone(TSH)increased(P<0.05),while FT3 and eGFR decreased(P<0.05).Spearman correlation analysis showed that UACR was positively correlated with age,HbA1c,TPOAb,TGAb,TSH(P<0.01),and negatively correlated with FT3(P<0.01).The UACR of the TGAb(+)+TPOAb(+)subgroup was higher than that of the TGAb(+)and TPOAb(+)subgroups(P<0.05).Logistic regression analysis showed that TSH,TGAb,TPOAb,and HbA1c were risk factors for MUAlb,while FT3 was a protective factor for MUAlb.Conclusions In T2DM with HT patients with normal thyroid function,TPOAb and TGAb are closely related to the occurrence of early renal injury.

Trihelix transcription factors play important roles in plant light responses, growth and development, and stress responses. However, Trihelix has not yet been reported in Eucommia ulmoides. In this study, bioinformatics methods were used to comprehensively identify and analyze the expression patterns of the Trihelix gene family in E. ulmoides, aiming to provide a basis for further functional studies of EuGTs genes. A total of 9 Trihelix gene family members were identified in E. ulmoides, encoding proteins with 339 to 883 amino acids, with isoelectric points ranging from 5.13 to 9.39 and relative molecular weights between 36 992.06 and 97 871.61. Subcellular localization results showed that only EuGT-2 was localized in chloroplasts, while the others were located in the nucleus. The Trihelix gene family was categorized into six subfamilies: GT-1, GT-2, SH4, SIP1, GTγ, and GTδ. EuGTs were distributed among three subfamilies: SH4, GT-1, and GT-2, containing 1, 6, and 2 Trihelix proteins, respectively, with 2 to 17 exons. The promoters of EuGTs contained various cis-acting elements related to hormones, stress, photoperiod, and growth and development. Collinearity analysis revealed 5 collinear gene pairs between E. ulmoides and Arabidopsis thaliana, and 14 collinear gene pairs between E. ulmoides and Populus. Expression pattern analysis showed that EuGTs exhibited tissue-specific expression: EuGT-1, EuGT-2 had the highest expression levels in leaves, EuGT-4, EuGT-6, EuGT-9 had the highest transcriptional levels in marginal peel, and EuGT-5、EuGT-8 were predominantly expressed in the xylem. As leaves developed, EuGTs showed a trend of asynchronous changes. No significant differences in EuGTs expression were observed between male and female flowers, with high expression levels mainly during the induction stage of flowering. The qRT-PCR analysis indicated that most EuGTs genes were most highly expressed in the leaves of E. ulmoides, while EuGT-5 was highly expressed in the stems. Under 200 mmol·L~(-1) NaCl treatment, most EuGTs genes exhibited an initial increase followed by a decrease in expression, significantly responding to salt stress. This study provides important genetic resources for further exploration of EuGTs gene functions and germplasm innovation in E. ulmoides.

Objective:To investigate the related risk factors related to patellar dislocation combined with osteochondral fracture (OCF).Methods:A case control study was conducted to analyze the clinical data of 278 patients with patellar dislocation admitted to Second Hospital of Lanzhou University from January 2016 to June 2020, including 98 males and 180 females; aged 12-41 years [(21.1±4.6)years]. The patients were divided into OCF group ( n=112) and non-OCF group ( n=166) according to the surgical records and occurrence of OCF or not under intraoperative arthroscopy. The data of the two groups were recorded, including basic characteristics (ie, sex, age, sides of injury, whether or not the epiphysis is closed), patella height, patellar inclination angle, tibial tubercle-trochlear groove (TT-TG), femoral trochlear shape, tibial lateral rotation angle and femoral anteversion angle. Univariate analysis was adopted to evaluate the correlation of the data with patellar dislocation combined with OCF. Multivariate Logistic regression analysis was used to determine the independent risk factors of patellar dislocation combined with OCF. Results:Univariate analysis showed that patellar dislocation combined with OCF was related to male, patellar inclination angle and femoral anteversion angle ( P<0.05 or 0.01), while not to age, epiphysis is closed or not, sides of injury, patella height, TT-TG, femoral trochlear shape and tibial lateral rotation angle (all P>0.05). Multivariate Logistic regression analysis showed that male ( OR=1.75, 95% CI 1.07-2.90, P<0.05) and increased femoral anteversion angle ( OR=3.12, 95% CI 1.89-5.17, P<0.05) were significantly correlated with patellar dislocation combined with OCF. Conclusion:Male and increased femoral anteversion angle are independent risk factors for patellar dislocation combined with OCF.
