ObjectiveTo investigate the fluctuations in serum uteroglobin-related protein 1（UGRP1） levels in Hashimoto’s thyroiditis （HT） patients before and after pregnancy， and to analyze the influencing factors. MethodsTen healthy individuals and ten HT patients were enrolled. Thyroid fine needle aspiration cytology combined with immunohistochemistry was used to detect the expression of UGRP1 protein in thyroid cells between the two groups. A total of 30 healthy women were enrolled as the control group， and 149 HT patients were recruited， including 36 non-pregnant HT patients， 77 pregnant HT patients and 36 post-partum HT patients. According to levothyroxine sodium （L-T4） administration status， the pregnant HT group was further subdivided into the non-L-T4 subgroup （n=36） and the L-T4 subgroup （n=41）. Kruskal-Wallis H test was used to compare the general clinical data， thyroid-related indicators and serum UGRP1 levels among groups. Spearman correlation analysis and univariate linear regression analysis were performed to explore the influencing factors of serum UGRP1 levels in HT patients. ResultsUGRP1 expression was negative in thyroid cells of all healthy individuals， while 80% of HT patients exhibited positive expression. The serum UGRP1 levels in the control group， non-pregnant HT group， pregnant HT group， and post-partum HT group were 359.52 （297.84， 440.60）， 695.77 （518.55， 865.04）， 207.96 （173.82， 264.91）， and 582.08 （280.83， 735.87） pg/mL， respectively， with statistically significant differences among groups （P<0.001）. Correlation analysis showed no significant correlation between serum UGRP1 levels and thyroid-related indicators or gestational age in pregnant HT patients. Univariate linear regression analysis revealed that pregnancy status was negatively correlated with serum UGRP1 levels in HT patients （β= -424.457， P<0.001）， while L-T4 administration had no statistically significant effect on serum UGRP1 levels in pregnant HT patients （P=0.890）. ConclusionSerum UGRP1 levels are significantly higher in HT patients than in healthy individuals. Pregnancy is an important factor affecting serum UGRP1 levels in HT patients， which can lead to a decrease in UGRP1 levels， while L-T4 administration has no significant effect on serum UGRP1 levels.

Objective : To explore the correlation between uteroglobulin-related protein 1(UGRP1) and primary hypothyroidism. Methods : Ninety-six patients with primary hypothyroidism were selected, including 66 patients with positive thyroid peroxidase antibodies(TPOAb) or anti-thyroglobulin antibodies(ATG) as the antibody-positive group, 30 patients with negative thyroid autoantibodies as the antibody-negative group, and 96 healthy people as the control group. The general clinical data, thyroid-related indicators and serum UGRP1 levels were compared among these three groups. Human thyroid normal cells(NTHY-ORI 3-1) were transfected with plasmids in vitro, thus establishing the control group as well as the UGRP1 group. Enzyme linked immunosorbent assay(ELISA) was used to detect and compare the T4 level in the cell culture supernatant. Results : The differences in thyroid stimulating hormone(TSH), TPOAb and ATG among the three groups were statistically significant(P<0.05). The serum UGRP1 levels in the antibody-positive(303.97±156.00) pg/ml and antibody-negative groups(352.13±188. 37) pg/ml were higher than those in the control group( 237. 54 ± 137. 20) pg/ml,and the differences between the groups were statistically significant( P = 0. 005). Meanwhile,there was no statistically significant difference between the antibody-positive and antibody-negative groups. Multi-factor Logistic regression analysis showed that UGRP1 was the risk factor for the occurrence of primary hypothyroidism( OR = 1. 004,95% CI: 1. 001-1. 007,P =0. 007). The difference between the control group and UGRP1 group in T4 concentration secreted by human thyroid normal cells was not statistically significant. Conclusion Serum UGRP1 levels increase in patients with primary hypothyroidism,and the high expression of UGRP1 may have no direct relation to the function of thyroid cells secreting T4.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

This article reports a case of membranous nephropathy in an adolescent accompanied by monoclonal IgG1-κ deposition. The 16-year-old female patient was hospitalized for experiencing proteinuria and hematuria for more than 20 days. The patient had a history of mycoplasma infection and acute kidney injury, and renal pathology revealed glomerular membrane lesions accompanied by crescent formation. Electron microscopy showed electron dense deposits in the subepithelial and mesangial regions, and immunofluorescence demonstrated monotypic IgG1-κ deposits in the glomerulus. Bone marrow examination did not find any abnormal plasma cells, nor were there significant abnormalities in serum or urine free light chain κ/λ ratio. The diagnosis was proliferative glomerulonephritis characterized by membranous lesions with monoclonal IgG1-κ deposits. This disease is rare in children and adolescents, and currently there is limited understanding of its mechanism, with limited clinical treatment experience. This article aims to provide clinical insights through case analysis and literature review.

BACKGROUND:Cervical neutral position magnetic resonance imaging is widely used for the diagnosis and treatment of cervical spondylotic myelopathy.However,it is not possible for patients to maintain the exact same position of the head and neck during repeated cervical magnetic resonance imaging examinations.The cervical spine undergoes minor flexion and extension movements in the sagittal plane,and the head may have a certain degree of variation in flexion and extension.Whether these changes in the neutral position of the cervical spine affect the volume of cervical discs herniation and cervical curvature is unclear. OBJECTIVE:Using artificial intelligence-assisted measurement,this study aimed to analyze the accuracy and reliability of magnetic resonance imaging examinations for measuring the volume of cervical discs herniation and cervical curvature in patients with cervical spondylotic myelopathy undergoing two consecutive cervical neutral positions in the short term. METHODS:A retrospective study was conducted on patients with cervical spondylotic myelopathy who underwent conservative treatment and underwent two consecutive cervical magnetic resonance imaging examinations within three months between June 2012 and June 2023.We proposed the use of occipital-thoracic distance and occipital-thoracic angle to evaluate the variation in flexion and extension of the head in the neutral position of the cervical spine.Based on the changes in occipital-thoracic angle,patients were divided into occipital-thoracic angle increase group and occipital-thoracic angle decrease group.Cervical discs herniation volume,C2-6 Cobb angle,and cervical(C3-C7)curvature were measured using artificial intelligence-assisted measurement software.Normal distribution data were represented by mean±SD,while non-normal distribution data were represented by the median(interquartile range).Spearman's rank correlation coefficient was used to analyze the correlation between changes in Cobb angle,cervical(C3-C7)curvature,and cervical discs herniation volume. RESULTS AND CONCLUSION:(1)A total of 104 patients and 326 cervical discs herniation were included in the study.There were 47 patients in the occipital-thoracic angle increase group and 57 patients in the occipital-thoracic angle decrease group.(2)Extension and flexion index of the head:There were no significant differences in occipital-thoracic distance and occipital-thoracic angle during the initial diagnosis and follow-up examination.The variation of occipital-thoracic distance was 0.035(3.23)mm,and the variation of occipital-thoracic angle was-0.31(3.28)°.The deviation range of occipital-thoracic distance and occipital-thoracic angle was small,and there was no significant correlation.(3)Cervical curvature index:There were no significant differences in C2-6 Cobb angle and C3-C7 curvature during the initial diagnosis and follow-up examination.There were no significant differences in C2-6 Cobb angle and C3-C7 curvature between the occipital-thoracic angle increase group and occipital-thoracic angle decrease group.(4)There was no significant difference in volume of cervical discs herniation during the initial diagnosis and follow-up examination.There was no significant difference in volume of cervical discs herniation between the occipital-thoracic angle increase group and occipital-thoracic angle decrease group.There was no significant correlation between the change of cervical discs herniation volume and the change of C2-6 Cobb angle and the cervical(C3-C7)curvature.(5)These results indicate that in the neutral position of the cervical spine,there were negligible minor flexion and extension movements in the sagittal plane,and the head was limited to a specific position.Although the head has a certain range of flexion and extension variation,it does not affect the accuracy and reliability of parameters including cervical discs herniation volume,C2-6 Cobb angle,and cervical(C3-C7)curvature.
