Short-term postoperative bacteriobilia or fungibilia in liver transplantation patients with donation after circulatory death allografts associated with a longer hospital stay: A single-center retrospective observational study in China.

Background: Normal bile is sterile. Studies have shown that cholangitis after liver transplantation (LT) was associated with a relatively poor prognosis. It remains unclear whether the bacteriobilia or fungibilia impact the patient outcomes in LT recipients, especially with donation after circulatory death (DCD) allografts, which was correlated with a higher risk of allograft failure.

Prospective population pharmacokinetic study of tacrolimus in adult recipients early after liver transplantation: A comparison of Michaelis-Menten and theory-based pharmacokinetic models.

Tacrolimus, a calcineurin inhibitor widely used as a potent immunosuppressant to prevent graft rejection, exhibits nonlinear kinetics in patients with kidney transplantation and nephrotic syndrome. However, whether nonlinear drug metabolism occurs in adult patients undergoing liver transplantation remains unclear, as do the main underlying mechanisms. Therefore, here we aimed to further confirm the characteristics of nonlinearity through a large sample size, and determine the potential influence of nonlinearity and its possible mechanisms.

[Effects of gravel content on runoff and sediment yield on Lou soil engineering accumulation slopes under simulated rainfall conditions.].

To investigate the effects of gravel content on runoff and sediment yield on Lou soil accumulation slopes, we conducted indoor simulation rainfall experiments and examined the characteristics of runoff and sediment yield on accumulation slopes with five gravel contents (10%, 20%, 30%, 40%, 50%) under four rainfall intensities (1.0, 1.5, 2.

Integrated multi-omics analysis identifies as a predictor of recurrence and a regulator of telomere maintenance in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and has a high recurrence rate. Accurate prediction of recurrence risk is urgently required for tailoring personalized treatment programs for individual HCC patients in advance. In this study, we analyzed a gene expression dataset from an HCC cohort with 247 samples and identified five genes including , , , , and as the variables for the prediction of HCC recurrence, especially the early recurrence.

Erratum to: Biphasic effects of TGFβ1 on BMP9-induced osteogenic differentiation of mesenchymal stem cells.

[Erratum to: BMB Reports 2012; 45(9): 509-514, PMID: 23010171] The BMB Reports would like to correct in the Figure 2 of BMB Rep. 2012; 45(9): 509-514 titled "Biphasic effects of TGFβ1 on BMP9-induced osteogenic differentiation of mesenchymal stem cells." The original version of this article unfortunately contained image assembling error in the Figure 2.

Expert consensus on management of metabolic disease in Chinese liver transplant recipients.

Metabolic disease, including diabetes mellitus, hypertension, dyslipidemia, obesity, and hyperuricemia, is a common complication after liver transplantation and a risk factor for cardiovascular disease and death. The development of metabolic disease is closely related to the side effects of immunosuppressants. Therefore, optimization of the immunosuppressive regimen is very important for the prevention and treatment of metabolic disease.

Infection within 2 weeks before liver transplantation closely related to prognosis of posttransplant infection: A single-center retrospective observational study in China.

Background: Infections still represent the main factors influencing morbidity and mortality following liver transplantation. This study aimed to evaluate the incidence and risk factors for infection and survival after liver transplantation.

Methods: We retrospectively examined medical records in 210 liver recipients who underwent liver transplantation between April 2015 and October 2017 in our hospital.

Copper-Catalyzed Asymmetric Annulation Reactions of Carbenes with 2-Iminyl- or 2-Acyl-Substituted Phenols: Convenient Access to Enantioenriched 2,3-Dihydrobenzofurans.

We have developed a method for the highly diastereo- and enantioselective construction of 2,3-dihydrobenzofurans bearing tetrasubstituted carbon stereocenters by means of annulation reactions between carbenes and 2-iminyl- or 2-acyl-substituted phenols through catalysis by readily accessible copper(I)/bisoxazoline catalysts under mild conditions. These reactions feature a unique mechanism in which the copper catalyst serves a dual function: first it reacts with the diazo compound to generate a metal carbene, and second, upon formation of an oxonium ylide, it acts as a Lewis acid to activate the imine or ketone for diastereo- and enantioselective cyclization.

The SMYD3 VNTR 3/3 polymorphism confers an increased risk and poor prognosis of hepatocellular carcinoma in a Chinese population.

Objective: Hepatocellular carcinoma (HCC) is one of the most lethal human malignancies in China, and the genetic link of hepatocarcinogenesis remains to be defined. Thus, we explored the role of SET and myeloid translocation protein 8, Nervy, and DEAF1 (MYND) domain containing protein 3 (SMYD3) gene polymorphism on risk and prognosis of HCC.

Methods: A total of 236 patients with HCC who received treatment in Affiliated Hospital of Jining Medical University for the first time and 230 healthy individuals were enrolled in the study.

MicroRNA-144 suppresses the expression of cytokines through targeting RANKL in the matured immune cells.

To investigate whether the microRNA-144 (miR-144) had immune regulation effect on matured immune cells, we firstly used quantitative RT-PCR (qRT-PCR) to detect the expression changes of miR-144 between the matured and immature dendritic cells (DCs), macrophages, and the peripheral blood mononuclear cells (PBMCs). Then we went on inspecting the expression changes of TNF-α, IL-1β, IL-6 and IL-23 in the matured DCs treated with miR-144 mimics or inhibitors using qRT-PCR, and also performed western blot to test phosphorylation state of ERK, JNK, p38 and p65 in these cells. Next, TargetScan was conducted to forecast the target gene of miR-144, receptor activator for nuclear factor-κB ligand (RANKL), and double luciferase reporter system was applied to research their banding sites.

A quantitative assessment model of T-cell immune function for predicting risks of infection and rejection during the early stage after liver transplantation.

Although more and more clinical studies indicated that ImmuKnow assay could efficiently assess the immune status of recipients, it still has the challenge to predict the occurrence of clinical adverse events. This study aimed to establish a quantitative assessment model, which could more efficiently predict immune function of T lymphocytes after liver transplantation based on three indexes: CD4+ T lymphocyte count (C), CD4+/CD8+ ratio (R), and ImmuKnow adenosine triphosphate (ATP) value (A). We selected 194 recipients and measured the A, C, and R index every week, then obtained the Fisher linear discriminant functions by SPSS 16.

The effect of adenovirus-mediated siRNA targeting BMPR-II on UHMWPE-induced osteoclast formation.

Aseptic loosening (AL) is the single most common complication of total joint arthroplasty. The critical factor may contribute to loosening is the adverse tissue response to wear debris. A growing body of literature suggests that BMPs influence the formation and activity of osteoclasts, and BMP signaling plays an important role in the osteoclast formation.

Biphasic effects of TGFβ1 on BMP9-induced osteogenic differentiation of mesenchymal stem cells.

We have found that the previously uncharacterized bone morphogenetic protein-9 (BMP9) is one of the most osteogenic factors. However, it is unclear if BMP9 cross-talks with TGFβ1 during osteogenic differentiation. Using the recombinant BMP9 adenovirus, we find that low concentration of rhTGFβ1 synergistically induces alkaline phosphatase activity in BMP9-transduced C3H10T1/2 cells and produces more pronounced matrix mineralization.

Inhibitory effect of adenovirus-mediated siRNA-targeting BMPR-IB on UHMWPE-induced bone destruction in the murine air pouch model.

Objective: Adenovirus expressing small interfering RNA (siRNA)-targeting BMPR-IB was locally administered into the air pouch of mice to improve bone resorption induced by ultra-high molecular weight polyethylene (UHMWPE) particles.

Method: Air pouches were established on the back of BALB/c mice, followed by the surgical introduction of a section of calvaria from a syngeneic mouse donor. The bone-implanted pouches were stimulated with the UHMWPE suspension.

[Interleukin-4 and osteoprotegerin suppress polyethylene wear debris-induced osteolysis in a murine air pouch model].

Objective: To test the effect of recombinant interleukin-4 (IL-4) and recombinant osteoprotegerin (OPG) in suppressing bone resorption induced by polyethylene wear particles..

Methods: A cranial bone allograft was introduced into the air pouches induced on the back of BALB/c mice, followed by injection of 1 ml suspension of polyethylene particles into the pouches.

Suppression of allograft rejection by Tim-1-Fc through cross-linking with a novel Tim-1 binding partner on T cells.

Engagement of T-cell immunoglobulin mucin (Tim)-1 on T cells with its ligand, Tim-4, on antigen presenting cells delivers positive costimulatory signals to T cells. However, the molecular mechanisms for Tim-1-mediated regulation of T-cell activation and differentiation are relatively poorly understood. Here we investigated the role of Tim-1 in T-cell responses and allograft rejection using recombinant human Tim-1 extracellular domain and IgG1-Fc fusion proteins (Tim-1-Fc).

Background: There have been increasing interests in the relationship between CD4(+) T lymphocytes and acute rejection (AR) in transplantation. In this study, we explore the role of CD4(+) T lymphocytes after liver transplantation.

Methods:   From February to October 2009, 87 patients underwent liver transplantation.

Liver transplantation for primary hepatic leiomyosarcoma: a case report and review of the literatures.

Primary hepatic leiomyosarcoma (PHL), a malignant mesenchymal tumor of myogenic origin, is exceedingly rare. Patients may be afflicted with a wide spectrum of nonspecific symptoms, and most of the laboratory data are unhelpful to diagnosis. Here, we report a 44-year-old woman with anorexia and right upper quadrant pain who was diagnosed as having malignant hepatic tumor within the Milan criteria and treated by orthotopic liver transplantation (OLT), the pathologic diagnosis of PHL was made by postoperative immunohistochemical study.
