However, the precise contribution of CD146⁺ endothelial cells to RIF remains unclear. This study aimed to observe and detect the relationship between CD146 expression and endothelial cells and to explore the role and possible mechanism of CD146 promoting endothelial-mesenchymal transition in RIF. MATERIAL AND METHODS In this study, we investigated the association between CD146⁺ endothelial cells and RIF. Double-label immunofluorescence was used in patients with chronic kidney disease, whereas multiplex immunofluorescence staining was used for the analysis in unilateral ureteral obstruction (UUO) mice. Hematoxylin and eosin and Masson trichrome staining were performed to evaluate RIF. RESULTS Our results revealed an elevation of CD146⁺ endothelial cells, which positively correlated with the degree of RIF in chronic kidney disease patients and UUO mice. Notably, CD146⁺ endothelial cells undergoing endothelial-mesenchymal transition (CD146⁺ EndMT) were significantly higher in subjects with severe renal interstitial fibrosis, as observed in chronic kidney disease patients and UUO mice. Additionally, with the progression of renal interstitial fibrosis, the expression of PDGFRb, the receptor of PDGF-B signaling pathway, increased and co-localized with CD146⁺ CD31⁺ a-SMA⁺ cells. The proportion of CD146⁺ CD31⁺ alpha-SMA⁺ PDGFRß⁺ cells in CD31⁺ cells increased. CONCLUSIONS In the process of renal interstitial fibrosis, CD146 is mainly expressed in renal interstitial vascular endothelial cells and participates in endothelial-to-mesenchymal transition, which may be related to the PDGF-B/PDGFR-ß signaling pathway.</p>","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"29 ","pages":"e945917"},"PeriodicalIF":1.1,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11645843/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142799141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with HPS (HPS group) and patients without HPS (non-HPS group) were included in our study. HPS is defined as a defect in arterial oxygenation caused by the presence of intrapulmonary vascular dilatations, which is found by transthoracic echocardiography with pre-existing liver cirrhosis. HPS severity was graded according to the value of partial pressure of arterial oxygen. The demographic characteristics and clinical outcomes between the HPS and non-HPS groups were compared.

Identifying the psychological factors associated with post-transplant PTSD would help to understand the symptoms of PTSD and take preventive measures. The aim of this study was to investigate factors influencing stress disorders in Intensive Care Unit (ICU) patients 1 year after LT. MATERIAL AND METHODS We assessed data from 184 LT patients at our hospital between January 2020 and December 2022. According to the PCL-C score, the patients were divided into the PTSD group (score ≤37) and the non-PTSD group (score >37). The demographic data, clinical data, the pain visual analogue scale (VAS), the anxiety and depression scale (HADS), and the psychological resilience scale (CD-RISC score) were compared between the 2 groups. Pearson correlation analysis was used to analyze the correlation between PCL-C and VAS, HADS, and CD-RISC, and logistic regression was used to analyze the factors influencing PTSD. SPSS 23.0 software was used for statistical analysis. RESULTS The average age of the 184 participants was 53.17 years (±3.47) and 66.85% of the subjects were male. The prevalence rate of post-transplant PTSD was 22.83% and the total score on the PCL-C scale was 32.47±7.81. Pearson correlation analysis showed that PCL-C score was positively correlated with VAS (r=0.312, P=0.012) and HADS (r=0.412, P<0.001), and negatively correlated with CD-RISC (r=-0.468, P<0.001).

This study's aim was to compile a 10-year summary of continuous renal replacement therapy (CRRT) experience at a single burn center, including patient outcomes, effectiveness, and potential complications in the context of severe burns. MATERIAL AND METHODS This retrospective analysis included the clinical data from 723 burned patients. The data analysis of 300 patients with CRRT therapy included clinical data, laboratory tests, and CRRT parameters. The study group was split into 2 subgroups regarding onset of CRRT: early (up to 7 days after the trauma) and late. RESULTS Age, burn extent, length of stay, and inhalation injury all had an impact on survival. Early CRRT was linked to a greater probability of death (P<0.005). Upon admission to the burn center, patients with early CRRT exhibited a bigger burn area, higher Baux and SOFA scores, and were younger (P<0.05).

The interview was semi-structured, featuring open-ended questions related to 5 domains: preference, emotions and temperament, memory, self-identity, and social identity. Qualitative data were analyzed by triangulation and deductive content analysis. Quantitative data were collected using the Big Five Inventory-19 (BFI-19) questionnaire, to complement the domain of emotions and temperament.

Here, we examined the GI-protective effects of apraglutide, a long-acting peptide GLP-2 analog, in murine models of chemotherapy, and total body irradiation followed by allogeneic transplantation. MATERIAL AND METHODS The impact of apraglutide on cytarabine or melphalan chemotherapy-induced intestinal damage was assessed in BALB/c mice, and the effect on allogeneic transplantation in BALB/cJ and C57BL/6J mice. Outcomes included survival, and changes in body weight, intestinal function and morphology, including colon length and bacterial composition of the intestinal microbiota. RESULTS Adding apraglutide to chemotherapy significantly improved survival rates and reduced weight loss, with no impact on leukocyte counts (and, therefore, no effect on chemotherapy-induced immunosuppression), compared with chemotherapy alone in mice. These benefits were associated with preservation of the morphological integrity of the GI mucosa, attenuation of the negative impact of cytarabine on the intestinal microbiota, and significant improvement in plasma levels of citrulline. In addition, in a model of irradiation followed by allogeneic transplantation, mice in groups receiving apraglutide had improved survival, reduced weight loss, and increased colon length compared with those that did not.
