Autoimmune thyroid diseases and type 1 diabetes mellitus commonly co-occur, and their co-occurrence can impair glycemic control and increase the risk of cardiovascular disease. Therefore, early identification and management of both conditions are important. This article aims to review the prevalence, incidence, and clinical evidence of co-occurrence of autoimmune thyroid diseases and type 1 diabetes mellitus, their shared pathogenic mechanisms, and considerations for screening and therapy.

BACKGROUND: Studies have classified muscle-invasive bladder cancer (MIBC) into primary (initially muscle-invasive, PMIBC) and secondary subtypes (initially non-muscle-invasive but progresses, SMIBC), for which controversial survival outcomes were demonstrated. This study aimed to compare the survival outcomes between PMIBC and SMIBC patients in China. METHODS: Patients diagnosed with PMIBC or SMIBC at West China Hospital from January 2009 to June 2019 were retrospectively included. Kruskal-Wallis and Fisher tests were employed to compare clinicopathological characteristics. Kaplan-Meier curves and Cox competing proportional risk model were used to compare survival outcomes. Propensity score matching (PSM) was employed to reduce the bias and subgroup analysis was used to confirm the outcomes. RESULTS: A total of 405 MIBC patients were enrolled, including 286 PMIBC and 119 SMIBC, with a mean follow-up of 27.54 and 53.30 months, respectively. The SMIBC group had a higher proportion of older patients (17.65% [21/119] vs. 9.09% [26/286]), chronic disease (32.77% [39/119] vs . 22.38% [64/286]), and neoadjuvant chemotherapy (19.33% [23/119] vs . 8.04% [23/286]). Before matching, SMIBC had a lower risk of overall mortality (OM) (hazard ratios [HR] 0.60, 95% confidence interval [CI] 0.41-0.85, P  = 0.005) and cancer-specific mortality (CSM) (HR 0.64, 95% CI 0.44-0.94, P  = 0.022) after the initial diagnosis. However, higher risks of OM (HR 1.47, 95% CI 1.02-2.10, P  = 0.038) and CSM (HR 1.58, 95% CI 1.09-2.29, P  = 0.016) were observed for SMIBC once it became muscle-invasive. After PSM, the baseline characteristics of 146 patients (73 for each group) were well matched, and SMIBC was confirmed to have an increased CSM risk (HR 1.83, 95% CI 1.09-3.06, P  = 0.021) than PMIBC after muscle invasion. CONCLUSIONS Compared with PMIBC, SMIBC had worse survival outcomes once it became muscle-invasive. Specific attention should be paid to non-muscle-invasive bladder cancer with a high progression risk.

Objective:To demonstrate the clinical significance of group A streptococcal infection (GAS) in patients with enthesitis related arthritis (ERA).Methods:A retrospective study was conducted on ERA (136) and PolyRF-/Oligo juvenile idiopathic arthritis (JIA) (272) patients in Beijing Children's Hospital from 2016 to 2018. Anti-streptococcal hemolysin "O" (ASO) was tested and documented in all patients. The infection rate of GAS was compared between patients with ERA and PolyRF-/Oligo JIA. Patients with ERA were divided to two groups according to the result of ASO (ASO positive and ASO negative). All the clinical data were documented and compared within the two groups. The statistical methods used mainly include t test, rank sum test, chi-square test, and Spearman correlation analysis.Results:The GAS infection rate of patients with ERA was higher than patients with PolyRF-/Oligo JIA (17.6% vs 9.5%, χ2=5.52, P=0.019). In ERA patients, clinical data were analyzed, and a statistical significant difference was observed in the presence of human leukocyte antigen (HLA)-B27 between ASO positive and ASO negative group [75.0%(18/24) vs 49.1%(55/112), χ2=5.329, P=0.021]. Statistical differences were found in Patrick's sign positive rate between the two groups [100%(24/24) vs 67.0%(75/112), χ2=10.61, P=0.001]. There was statistically significant difference between the two groups regarding the radiogr-aphic grading at the sacroiliac joint. More patients with positive ASO had grade Ⅲ damage at the sacroiliac joint compare to patients with negative ASO [68.2%(15/22) vs 28.4%(29/102), χ2=12.49, P<0.001]. The logarithmic of the ASO was slightly correlated with the radiographic grade of sacroiliac joint ( r=0.26, P=0.005). Conclusion:Patients with ERA are prone to be infected by GAS. It's probably related to HLA-B27 postivity for antigen presentation. Patients who were infected by GAS fre-quently have sacroiliac joint involvement, and tend to be more sever. This indicates that GAS may play an important role in the pathogenesis of sacroiliac joint destruction.

Despite being a common therapy for hepatocellular carcinoma (HCC), insufficient thermal ablation can leave behind tumor residues that can cause recurrence. This is believed to augment M2 inflammatory macrophages that usually play a pro-tumorigenic role. To address this problem, we designed d-mannose-chelated iron oxide nanoparticles (man-IONPs) to polarize M2-like macrophages into the antitumor M1 phenotype. In vitro and in vivo experiments demonstrated that man-IONPs specifically targeted M2-like macrophages and accumulated in peri-ablation zones after macrophage infiltration was augmented under insufficient microwave ablation (MWA). The nanoparticles simultaneously induced polarization of pro-tumorigenic M2 macrophages into antitumor M1 phenotypes, enabling the transformation of the immunosuppressive microenvironment into an immunoactivating one. Post-MWA macrophage polarization exerted robust inhibitory effects on HCC progression in a well-established orthotopic liver cancer mouse model. Thus, combining thermal ablation with man-IONPs can salvage residual tumors after insufficient MWA. These results have strong potential for clinical translation.

Objective To assess the usefulness of the MSCTA with 3D reconstruction to epigastric tumors in interventional treatment.Methods MSCTA were performed in 27 cases of epigastric tumors before and after interventional treatment.3D reconstruction were taken for blood vessels with technique of MIP(maximum intensity projection)and VRT(volume rendering technique).Results 42 times MSCTA and 3D reconstruction were performed in 27 cases of epigastric tumors.We discovered 5 feeding arteries with mutation in abdominal cavity,7 collateral branches formed after embolization and 2 abnormal courser of celiac artery.The display of vasculative with MSCTA was better than that of DSA.Conclusion 3D-MSCTA for epigastric tumors not only can show directly and clearly the stereo-anotomic images of the tumor feeding vessels but also provide guidance for planning the treatment.
