Study of clinical practical model of urinary system injury.

Background: In order to improve the clinical treatment level of urinary system injury, it is necessary to build up an animal model of urinary system wound, which is not only analogous to real clinical practice, but also simple and practical.

Methods: We have developed the third generation of firearm fragment wound generator based on the first and the second producer. The best explosive charge of the blank cartridge was selected by gradient powder loading experiments.

Dynamic expression changes between non-muscle-invasive bladder cancer and muscle-invasive bladder cancer.

Aims And Background: Despite elaborate characterization of the risk factors, bladder cancer is still a major epidemiological problem whose incidence continues to rise each year. We aim to investigate the dynamic expression changes between non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC).

Methods: The gene expression profile GSE13507 was obtained from the Gene Expression Omnibus, and the R package was used to identify gene expression signatures (GESs) between NMIBC and MIBC.

The association between fish consumption and risk of renal cancer: a meta-analysis of observational studies.

Background: Several case-control studies and cohort studies have investigated the association between fish intake and renal cancer risk, however, they yielded conflicting results. To our knowledge, a comprehensive assessment of the association between fish consumption and risk of renal cancer has not been reported. Hence, we conducted a systematic literature search and meta-analysis to quantify the association between fish consumption and renal cancer.

Clinical efficacy of rituximab for acute rejection in kidney transplantation: a meta-analysis.

Objectives: This meta-analysis was undertaken to compare the efficacy and safety of pretransplant treatment with rituximab in sensitized patients receiving kidney transplantation.

Methods: PubMed, EMBASE, and Cochrane databases were searched to identify studies that used pretransplantation rituximab in eligible patients. The major outcomes included antibody-mediated rejections (AMR) after kidney transplantation and one-year graft survival rate.

Association of vitamin D receptor FokI and ApaI polymorphisms with human cytomegalovirus disease in the first three months following kidney transplantation.

Background: Untreated human cytomegalovirus (CMV) disease (CMVD) is an identified risk factor for reduced rates of patient (and graft) survival, death or retransplantation in kidney transplant recipients due to increased immunological tolerance after transplant. Vitamin D receptor (VDR) gene polymorphisms have an obvious relationship with autoimmune diseases but the relationship between VDR gene polymorphisms and CMVD are not well understood. This study investigated the relationship between VDR FokI and ApaI gene polymorphisms and CMVD, and their value for predicting risk of CMVD.

[Applications of monitoring human leukocyte antigen G and its inhibitory receptors in post-renal transplantation].

Objective: to study the feasibility of human leucocyte antigen-G (HLA-G) as a post-transplantation prognostic biomarker and discuss the correlation of its receptor expression and the mechanisms.

Methods: a total of 215 recipients in our centre from February 2006 to June 2008 were divided into stable kidney function group (n = 173) and acute rejection group (n = 42). The soluble human leucocyte antigen-G5 (sHLA-G5) level in peripheral plasma was detected by ELISA.

Uptake of donor lymphocytes treated with 8-methoxypsoralen and ultraviolet A light by recipient dendritic cells induces CD4+CD25+Foxp3+ regulatory T cells and down-regulates cardiac allograft rejection.

Extracorporeal photopheresis (ECP) is an effective immunomodulatory therapy and has been demonstrated to be beneficial for graft-vs-host disease and solid-organ allograft rejection. ECP involves reinfusion of a patient's autologous peripheral blood leukocytes treated ex vivo with 8-methoxypsoralen and UVA light radiation (PUVA). Previous studies focused only on ECP treatment of recipient immune cells.

Rapamycin inhibits cholangiocyte regeneration by blocking interleukin-6-induced activation of signal transducer and activator of transcription 3 after liver transplantation.

Cholangiocyte proliferation is necessary for biliary recovery from cold ischemia and reperfusion injury (CIRI), but there are few studies on its intracellular mechanism. In this process, the role of rapamycin, a new immunosuppressant used in liver transplantation, is still unknown. In order to determine whether rapamycin can depress cholangiocyte regeneration by inhibiting signal transducer and activator of transcription 3 (STAT3) activation, rapamycin (0.

[Impact of novel negative immunoregulatory dendritic cells on regulatory T cells in cardiac allograft recipient rats].

Aim: To investigate the effect of recipient dendritic cells (DC) loaded with PUVA-treated donor splenic lymphocytes (PUVA-SP) on CD4(+) CD25(+) regulatory T cells (Treg) and the survival time of cardiac allograft in rats.

Methods: Cardiac allografts from DA donor rats were transplanted into LEW recipient rats. Donor splenic lymphocytes were treated with 8-methoxypsoralen plus UVA irradiation (PUVA).

[Role of the activation of interleukin-6/STAT3 in cholangiocyte proliferation induced by cold ischemia reperfusion and injury].

Objective: To investigate the role of IL-6/STAT3 pathway in the proliferation of cholangiocyte induced by cold ischemia and reperfusion injury.

Methods: Rats were randomized into CP 1 h and CP 12 h groups (supplied livers were preserved for 1 or 12 h), anti-IL-6R (rats in CP 12 h group were administrated with anti-rat soluble IL-6 receptor antibody), and control group. At 1, 3, 7, 14 d postoperative, IL-6 concentration in liver homogenate and cholangiocyte proliferation were detected by enzyme linked immunosorbent assay and histochemistry respectively.

[Pathogenesis of post-transplantation diabetes mellitus in 40 renal transplantation recipients].

Objective: To explore pathogenesis of post-transplantation diabetes mellitus (PTDM) in renal transplantation recipients.

Methods: A total of 40 renal transplantation recipients were divided into three groups based on oral glucose tolerance test results: normal glucose tolerance (NGT) group (n = 10), impaired fasting glycaemia + impaired glucose tolerance (IFG + IGT) group (n = 16), and PTDM group (n = 14). Insulin resistance (IR) and beta cell function were assessed by homeostasis model.

[Risk factors of long-term cardiovascular diseases and cerebrovascular diseases in kidney allograft recipients].

Objective: To identify the risk factors of cardiovascular diseases and cerebrovascular diseases (CVD) events in kidney allograft recipients.

Methods: We followed up 361 renal transplant recipients who had undergone renal transplantation in our center from January 2000 to December 2003 and evaluated the cumulative incidences and mortalities of CVD complications at baseline and post-transplantation 1, 3, 6, 12, 24, 36, 48, and 60 months. Kaplan-Meier plot was used to assess the incidence and Cox's proportional hazards model to determine the risk factors for cardiovascular complications.

Objective: To investigate whether lipopolysaccharide (LPS) stimulates cholangiocyte proliferation via the IL-6/STAT3 pathway in vivo.

Methods: Rats were randomized into three groups: LPS group (injected intravenously with LPS 2.5 mg/kg), anti-IL-6 group (injected intravenously with anti-IL-6 0.

Activation of interleukin-6/STAT3 in rat cholangiocyte proliferation induced by lipopolysaccharide.

Background: Cholangiocytes are exposed to endotoxins (lipopolysaccharide, LPS) in a variety of biliary inflammations. It is known that LPS enhances the release of interleukin (IL)-6, a potent cholangiocyte mitogen. However, the role of LPS in cholangiocyte proliferation in vivo is unknown.

Short-term anti-CD25 monoclonal antibody treatment and neogenetic CD4(+)CD25(high) regulatory T cells in kidney transplantation.

CD4(+)CD25(high) T cells named regulatory T (Treg) cells are generated and play a key role in the induction and maintenance of transplant tolerance in organ recipients. Interleukin-2 (IL-2) enhance the development of effector cells and is essential for generation of Treg cells. The effect of the anti-CD25 monoclonal antibody (anti-CD25mAb) induction therapy on the neogenetic CD4(+)CD25(high)Treg cells is important for therapeutic strategies in kidney transplant.

Endothelial cell chimerism by fluorescence in situ hybridization in gender mismatched renal allograft biopsies.

Background: The blood vessels of a transplanted organ are the interface between donor and recipient. The endothelium in the blood vessels is thought to be the major target for graft rejection. Endothelial cells of a transplanted organ can be of recipient origin after transplantation.
