Pulmonary embolism and hemorrhage after displacement of angiographic catheter tip to pulmonary artery: A case report and literature review.

Pulmonary embolism and massive hemoptysis caused by intravascular foreign bodies have rarely been reported. We report a case of an end-stage renal disease patient in which the tip of the angiographic catheter fell off into the pulmonary artery during endovascular interventional opening when the patient underwent vascular access occlusion for dialysis. During the operation, the foreign body was displaced repeatedly and finally anchored to the posterior basal segment branch of the right lower pulmonary artery.

Imaging misdiagnosis and clinical analysis of significant hepatic atrophy after bilioenteric anastomosis: A case report.

Background: The occurrence of long-term bilioenteric anastomotic stenosis can readily induce liver atrophy and hyperplasia, thereby causing significant alterations in the anatomical and morphological aspects of the liver. This condition significantly hampers the accuracy of preoperative imaging diagnosis, while also exacerbating the complexity of surgical procedures and the likelihood of complications.

Case Summary: A 60-year-old female patient was admitted to the hospital presenting with recurring epigastric pain accompanied by a high fever.

Wernicke's encephalopathy after acute pancreatitis with upper gastrointestinal obstruction: A case report and literature review.

A 42-year-old female was admitted with upper abdominal pain. Imaging studies and laboratory tests were performed to consider acute lipogenic pancreatitis. After symptomatic treatment, her abdominal pain was significantly relieved.

Control system of neoclassical tearing modes in real time on HL-2A tokamak.

The stability and performance of tokamak plasmas are routinely limited by various magneto-hydrodynamic instabilities, such as neoclassical tearing modes (NTMs). This paper presents a rather simple method to control the NTMs in real time (RT) on a tokamak, including the control principle of a feedback approach for RT suppression and stabilization for the NTMs. The control system combines Mirnov, electron cyclotron emission, and soft X-ray diagnostics used for determining the NTM positions.

Augmenter of liver regeneration attenuates acute rejection after rat liver transplantation.

Background: The role of augmenter of liver regeneration (ALR) on liver transplantation immune regulation remains unknown.

Methods: Male Lewis and Brown-Norway (BN) rats were assigned to allograft group (Lewis-to-BN liver transplantation), isograft group (BN-to-BN), and ALR group (Lewis-to-BN, ALR, 100 μg/kg/d, intramuscular injection postoperatively). Rats were sacrificed at indicated times for assessment of cytokines production, T-cell (TC) activation and apoptosis.

Development of a low-drift integrator system on the HL-2A tokamak.

In this work, we developed a new integrator system with low-drift and small integration time constant less than 1 ms, which applies to the weak signals from magnetic measurements. This integrator system is designed on the basis of the analog drift compensation and the real-time digital correction of residual drift. The analog drift compensation is achieved by the subtraction between two integrators and the digital correction method is available due to the stability of integral drift in short time scale.

Traumatic diaphragmatic rupture with combined thoracoabdominal injuries: Difference between penetrating and blunt injuries.

Purpose: Traumatic diaphragmatic rupture (TDR) needs early diagnosis and operation. However, the early diagnosis is usually difficult, especially in the patients without diaphragmatic hernia. The objective of this study was to explore the early diagnosis and treatment of TDR.

Knockdown of microRNA-155 in Kupffer cells results in immunosuppressive effects and prolongs survival of mouse liver allografts.

Background: Our previous studies have shown that Kupffer cells (KCs) play a crucial role in postoperative pathologic changes. Recent reports have demonstrated that microRNA-155 (miR-155) is associated with inflammation and upregulation of proinflammatory mediators in the peripheral blood and allografts of transplant patients. However, the precise mechanism for this remains unknown.

Correlation between augmenter of liver regeneration and IFN-γ expression in graft after rat orthotopic liver transplantation.

Background: Previous data suggested that augmenter of liver regeneration (ALR) has immunomodulation function by suppressing liver-resident NK cell activity and reducing IFN-γ expression in human liver diseases. The correlation between ALR and IFN-γ expression in graft after rat orthotopic liver transplantation remains uncertain.

Methods: A Lewis-to-BN (allograft group) and BN-to-BN (isograft group) rat liver transplantation model was used to investigate the ALR and IFN-γ expression in liver graft.

Effect of taurine on IRAK4 and NF-kappa B in Kupffer cells from rat liver grafts after ischemia-reperfusion injury.

Background: The aim of this study was to explore the protective mechanisms of taurine pretreatment against hepatic ischemia/reperfusion injury after liver transplantation.

Methods: A Sprague-Dawley-to-Sprague-Dawley rat liver transplantation model was used in this study. At 0, 60, and 180 minutes after reperfusion, expression of interleukin-1 receptor-associated kinase-4 (IRAK-4) messenger ribonucleic acid and protein in Kupffer cells was determined by real-time polymerase chain reaction and Western blotting.

Protective effect of glutamine-enriched early enteral nutrition on intestinal mucosal barrier injury after liver transplantation in rats.

Background: The effect of glutamine-enriched early enteral nutrition (Gln-EEN) on intestinal mucosal barrier injury after liver transplantation (LT) remains uncertain.

Methods: The Wistar-to-Wistar rat LT model was used to explore the protective effect of Gln-EEN. Morphologic changes of intestinal mucosa, levels of intestinal malondialdehyde and secretory immunoglobulin (sIgA), plasma endotoxin, D-lactic acid, serum tumor necrosis factor-alpha (TNF-alpha), rates of bacterial translocation, and expression of intestinal nuclear factor-kappaB, TNF-alpha, and intercellular adhesion molecule-1 were determined.

Blockade of inducible costimulator pathway to prevent acute rejection in rat liver transplantation.

Background: The role of inducible costimulator (ICOS) in transplantation immunity remains unclear.

Methods: A Lewis-to-Brown-Norway (BN) rat liver transplant model was used to explore the effect of ICOS blockade by small interference RNA. Recipient survival rate, number of CD25/ICOS-positive cells, ICOS mRNA and protein levels, and interferon-gamma and tumor-necrosis factor-alpha levels were determined.

Knockdown of interleukin-2 by shRNA-mediated RNA interference prolongs liver allograft survival.

Interleukin-2 (IL-2) plays a central role in T-cell activation, expansion, and homeostasis. The failure of IL-2 biosynthesis may play a critical role in tolerance induction. We tested the effect of IL-2 blockade by short hairpin RNA (shRNA) on regulating acute rejection in rat liver transplantation.

Role of Kupffer cells in the induction of tolerance of orthotopic liver transplantation in rats.

Because the role of Kupffer cells (KCs) in liver transplantation (LT) tolerance is not well understood, we investigated their role in liver allograft acceptance in rats. Male Sprague-Dawley rats were randomly assigned to either an LT group or a transplantation group pretreated with GdCl(3) (Gd group). The rats were postoperatively sacrificed at indicated times for histology and assessment of KC function, nuclear factor kappa B (NF-kappaB) activity, and cytokine production.
