Abstract
Primary graft dysfunction (PGD) is one of the most common complications in the early postoperative period and is the most common cause of death in the first postoperative month. The underlying pathophysiology is thought to be the ischaemia–reperfusion injury that occurs during the storage and reperfusion of the lung engraftment; this triggers a cascade of pathological changes, which result in pulmonary vascular dysfunction and loss of the normal alveolar architecture. There are a number of surgical and anaesthetic factors which may be related to the development of PGD. To date, although treatment options for PGD are limited, there are several promising experimental therapeutic targets. In this review, we will discuss the pathophysiology, clinical management and potential therapeutic targets of PGD.

Che D, Adams S, Zhao B, Qin G, Jiang H. Effects of Dietary L-arginine Supplementation from Conception to Post- Weaning in Piglets. Curr Protein Pept Sci 2019; 20:736-749. [PMID: 30678624 DOI: 10.2174/1389203720666190125104959] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Revised: 12/30/2018] [Accepted: 01/10/2019] [Indexed: 12/13/2022]
Abstract
Weaned piglets experience sudden changes in their dietary patterns such as withdrawal from the easily digestible watery milk to a coarse cereal diet with both systemic and intestinal disruptions coupling with the expression of pro-inflammatory proteins which affects the immune system and the concentrations of haptoglobin including both positive and negative acute-phase proteins in the plasma. L-arginine is an important protein amino acid for piglets, but its inadequate synthesis is a nutritional problem for both sows and piglets. Recent studies indicated that dietary supplementation of L-arginine increased feed intake, uterine growth, placental growth and nutrient transport, maternal growth and health, embryonic survival, piglets birth weight, piglet's growth, and productivity, and decreased stillbirths. L-arginine is essential in several important pathways involved in the growth and development of piglets such as nitric oxide synthesis, energy metabolism, polyamine synthesis, cellular protein production and muscle accretion, and the synthesis of other functional amino acids. However, the underlying molecular mechanism in these key pathways remains largely unresolved. This review was conducted on the general hypothesis that L-arginine increased the growth and survival of post-weaning piglets. We discussed the effects of dietary L-arginine supplementation during gestation, parturition, lactation, weaning, and post-weaning in pigs as each of these stages influences the health and survival of sows and their progenies. Therefore, the aim of this review was to discuss through a logical approach the effects of L-arginine supplementation on piglet's growth and survival from conception to postweaning.

Abstract
Bioactive components of dietary phytochemicals have been reported to possess antitumor activities. Evidences suggested key role of stress responsive p38MAPK in the induction of nutraceuticals mediated apoptosis in hepatocellular carcinoma (HCC). Current study demonstrated detailed molecular bagatelle associated with p38 MAPK mediated effective suppression of cell growth both in HepG2 and chemically induced liver carcinoma after S-allyl cysteine (SAC) treatment. SAC promoted p38MAPK activity responsible for p53 phosphorylation, its stabilization followed by nuclear translocation leading to induction in expression and oligomerization of Fas protein. Distinctive p38MAPK-p53 axis dependent Fas-FasL-FADD mediated caspase activities along with perturbed cell cycling became normalized with continuation of SAC treatment for another month to diethylnitrosamine induced liver carcinoma. Co-treatment with SB203580, the p38MAPK inhibitor, prevented pro-apoptotic effect of SAC by altering p53 phosphorylation and death inducing signaling complex conformation in HepG2 and induced HCC. Collectively study suggested significant contribution of p38MAPK-p53-DISC-Caspase pathway in the regulation of anti-neoplastic activity of SAC against HCC.

Abstract
A surge in cortisol levels is seen after surgery with cardiopulmonary bypass (CPB). Based on evidence of attenuation of the cortisol response to repeated stress in other settings, we hypothesized that the magnitude of cortisol increase in children after a second exposure to CPB would be reduced. Serial cortisol levels were measured at three time points after each CPB: immediately (day 0), on the first morning (day 1), and second morning (day 2). Forty-six children underwent two surgeries with CPB during the study period. The mean age (standard deviation) at first and second surgery was 3.5 (6.3) months and 10.4 (9.9) months, respectively. Cortisol levels at the first surgery were 109 (105) µg/dl, 29 (62) µg/dl, and 17 (12) µg/dl on day 0, 1, and 2, respectively; similarly at second surgery, it was 61 (57) µg/dl on day 0 to 20 (16) µg/dl and 11 (10) µg/dl on day 1 and 2, respectively. After log-transformation and adjusting for time interval between surgeries, cortisol levels at the second surgery were lower by 42% on day 0 (p = 0.02), and 46% lower on day 2 (p = 0.02). A second exposure to CPB in children with congenital heart disease is associated with an attenuated cortisol release.

Abstract
Ischemic preconditioning (IP) is one of the most important endogenous mechanisms that protect the cells against ischemia-reperfusion (I/R) injury. However, the exact molecular mechanisms remain unclear. In this study, we showed that changes in the level of agmatine were correlated with ischemic tolerance. Changes in brain edema, infarct volume, level of agmatine, and expression of arginine decarboxylase (ADC) and nitric oxide synthases (NOS; inducible NOS [iNOS] and neural NOS [nNOS]) were analyzed during I/R injury with or without IP in the rat brain. After cerebral ischemia, brain edema and infarct volume were significantly reduced in the IP group. The level of agmatine was increased before and during ischemic injury and remained elevated in the early reperfusion phase in the IP group compared to the experimental control (EC) group. During IP, the level of plasma agmatine was increased in the early phase of IP, but that of liver agmatine was abruptly decreased. However, the level of agmatine was definitely increased in the ipsilateral and contralateral hemisphere of brain during the IP. IP also increased the expression of ADC—the enzyme responsible for the synthesis of endogenous agmatine—before, during, and after ischemic injury. In addition, ischemic injury increased endogenous ADC expression in the EC group. The expression of nNOS was reduced in the I/R injured brain in the IP group. These results suggest that endogenous increased agmatine may be a component of the ischemic tolerance response that is induced by IP. Agmatine may have a pivotal role in endogenous ischemic tolerance.

Abstract
BACKGROUND Although commonly performed in adult swine, unilateral pneumonectomy in piglets requires significant modifications in the surgical approach and perioperative care because of their smaller size and limited physiological reserve. METHODS Nineteen neonatal piglets underwent a left pneumonectomy. They were allowed 5-7 d of preoperative acclimation and nutritional optimization. Preoperative weight gain and laboratory values were obtained before the time of surgery. A "ventro-cranial" approach is adopted where components of the pulmonary hilum were sequentially identified and ligated, starting from the most ventral and cranial structure, the superior pulmonary vein. The principle of gentle ventilation was followed throughout the entire operation. RESULTS The median age of the piglets at the time of surgery was 12 (10-12) d. The median preoperative weight gain and albumin level were 20% (16-26%) and 2.3 (2.1-2.4) g/dL, respectively. The median operative time was 59 (50-70) min. Five of the first nine piglets died from complications, two from poor preoperative nutritional optimization (both with <10% weight gain and 2 g/dL for albumin), one from an intubation complication, one from intra-operative bleeding, and one in the postoperative period from a ruptured bulla. No mortality occurred for the next 10 cases. CONCLUSIONS Successful outcomes for unilateral pneumonectomy in piglets require special attention to preoperative nutritional optimization, gentle ventilation, and meticulous surgical dissection. Preoperative weight gain and albumin levels should be used to identify appropriate surgical candidates. The "ventro-cranial" approach allows for a technically straightforward completion of the procedure.

Abstract
OBJECTIVES Our study aimed to determine whether antithrombin plays a synergistic role in accentuating the effects of intestinal ischemic preconditioning. MATERIALS AND METHODS Fifty rats were randomly allocated to 5 groups (10 rats/group) as follows: sham treatment (group 1); ischemia-reperfusion (group 2); ischemic preconditioning followed by ischemia-reperfusion (group 3); antithrombin + ischemia-reperfusion, similar to group 2 but including antithrombin administration (group 4); and antithrombin + ischemic preconditioning, similar to group 3 but including antithrombin administration (group 5). Blood samples and liver specimens were obtained for measurement of cytokines, myeloperoxidase, and malondialdehyde. Liver biopsies were examined by electron microscopy. RESULTS Intestinal ischemia-reperfusion induced a remote hepatic inflammatory response as evidenced by the striking increase of proinflammatory cytokines, myeloperoxidase, and malondialdehyde. Tumor necrosis factor-α levels in group 5 (12.48 ± 0.7 pg/mL) were significantly lower than in group 3 (13.64 ± 0.78 pg/mL; P = .014). Mean interleukin 1β was lower in group 5 (9.52 ± 0.67pg/mL) than in group 3 (11.05 ± 1.9 pg/mL; P > .99). Mean interleukin 6 was also significantly lower in group 5 (17.13 ± 0.54 pg/mL) than in group 3 (23.82 ± 1 pg/mL; P ≤ .001). Myeloperoxidase levels were significantly higher in group 3 (20.52 ± 2.26 U/g) than in group 5 (18.59 ± 1.03 U/g; P = .025). However, malondialdehyde levels did not significantly improve in group 5 (4.55 ± 0.46 μmol) versus group 3 (5.17 ± 0.61 μmol; P = .286). Tumor necrosis factor-α, interleukin 6, and myeloperoxidase findings show that antithrombin administration further attenuated the inflammatory response caused by ischemia-reperfusion, suggesting a synergistic effect with ischemic preconditioning. These findings were confirmed by electron microscopy. CONCLUSIONS The addition of antithrombin to ischemic preconditioning may act to attenuate or prevent damage from ischemia-reperfusion injury by inhibiting the release of cytokines and neutrophil infiltration.

Abstract
BACKGROUND Blood reperfusion after ischemia is the main measure to restore cell function. This study was aimed to explore the effect of propofol on rat and cell models of liver ischemia-reperfusion (I/R) injury, and to investigate its possible mechanism. METHODS Wistar rats were divided into four groups: control group, sham group, I/R group, and propofol group. Human hepatocyte HL7702 was divided into six groups: control group, I/R group and propofol (5, 10, 20 and 40 µmol/L) groups. After the animal and cell models were established, the alanine aminotransferase (ALT), aspartate aminotransferase (AST), malondialdehyde (MDA) and adenosine triphosphate (ATP) levels in liver tissues and hepatocytes were measured. Cell viability and apoptosis of hepatocytes were respectively determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and flow cytometry. Furthermore, the expressions of apoptosis-related proteins in hepatocytes were determined by Western blot analysis. RESULTS ALT, AST and MDA levels were all decreased significantly, and the ATP level was increased significantly in propofol group compared with that in I/R group in both liver tissues and hepatocytes. Additionally, cell viability of hepatocytes in propofol group was higher than that in I/R group, while the percentage of apoptotic cells in propofol group was less than that in I/R group. Moreover, the expression of caspase-3 decreased and the expression of Bcl-2 increased significantly after propofol preconditioning. CONCLUSIONS Our findings suggested that propofol preconditioning might be an effective strategy for protecting the liver from I/R injury, which might provide a scientific basis for clinical application.

Abstract
Reducing oxidative stress is crucial to prevent hypoxia-reoxygenation (H/R)-induced lung injury. Resveratrol has excellent antioxidant and anti-inflammatory effects, and this study investigated its role in H/R-induced type II pneumocyte dysfunction. H/R conditions increased expression of inflammatory cytokines including interleukin (IL)-1β (142.3 ± 21.2%, P < 0.05) and IL-6 (301.9 ± 35.1%, P < 0.01) in a type II alveolar epithelial cell line (A549), while the anti-inflammatory cytokine IL-10 (64.6 ± 9.8%, P < 0.05) and surfactant proteins (SPs) decreased. However, resveratrol treatment effectively inhibited these effects. H/R significantly activated an inflammatory transcription factor, nuclear factor (NF)-κB, while resveratrol significantly inhibited H/R-induced NF-κB transcription activities. To the best of our knowledge, this is the first study showing resveratrol-mediated reversal of H/R-induced inflammatory responses and dysfunction of type II pneumocyte cells in vitro. The effects of resveratrol were partially mediated by promoting SP expression and inhibiting inflammation with NF-κB pathway involvement. Therefore, our study provides new insights into mechanisms underlying the action of resveratrol in type II pneumocyte dysfunction.

Abstract
This study is aimed to investigate the efficacy and underlying the mechanism of propofol in treatment of ischemia reperfusion (IR)-induced lung injury in rats, providing a novel insight of therapeutic strategy for IR-induced lung injury. 120 healthy SD rats were selected and randomly divided into sham operation group, IR group, and propofol group (40 rats per group). Bronchoalveolar lavage fluid (BALF) protein content, serum protein content, lung permeability index, lung water content rate, methane dicarboxylic aldehyde (MDA) in lung tissue, superoxide dismutase (SOD), nitric oxide (NO), endothelin (ET-1), toll-like receptor 4 (TLR4), nuclear factor (NF-κB), and tumor necrosis factor-α (TNF-α) were examined and compared among different groups to evaluate the therapeutical effects of propofol on IR-induced lung injury and analyze the mechanism. In sham operation group, neither change in lung tissue nor pulmonary interstitial edema or alveolar wall damage was found under microscope; in IR group, marked pulmonary interstitial edema and alveolar wall damage complicated with inflammatory cell infiltration and hemorrhage were found; in propofol group, alveolar wall widening was observed, however, hemorrhage in alveolar cavity, inflammatory infiltration and tissue damage were less significant than in IR group. At 3 h after reperfusion, BALF protein content, lung permeability index, and lung water content rate were all significantly increased in IR group and propofol group, while the serum protein content was significantly lower than sham operation group (p < 0.05). Moreover, we found that the change of above parameters in propofol group was less significant than in IR group (p < 0.05). No statistically significant difference was found in ET-1 levels in different groups (p > 0.05). In contrast, MDA and NO in IR group and propofol group were significantly increased, while SOD activity was significantly decreased (p < 0.05). Furthermore, the change of above parameters in propofol group was less significant than in IR group (p < 0.05). In addition, mRNAs of TLR4, NF-κB, and TNF-α were significantly increased in IR group and propofol group (p < 0.05) with more significant change in IR group compared with propofol group (p < 0.05). Propofol has protective effects against IR-induced lung injury by improving activity of oxygen radical and restoring NO/ET-1 dynamic balance. Besides, regulation of TLR4, NF-κB, and TNF-α by propofol also play important role in alleviating IR-induced lung injury.

[PMID: 25034934 DOI: 10.1016/j.yexmp.2014.07.008] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2014] [Accepted: 07/12/2014] [Indexed: 12/29/2022]
Abstract
FTY720, sphingosine 1 phosphate (S1P) receptor agonist, is a potent immunosuppressive agent. Numerous studies have documented a relationship between S1P and cardioprotection. We therefore hypothesized that a S1P analogue FTY720 would attenuate hypoxia/reoxygenation (H/R) induced cadiomyocyte apoptosis. H9C2 cardiomyocytes were employed to establish an in vitro model of H/R. Cells were treated or not with different doses of FTY720. Cell viability was measured by flow cytometry and TUNEL staining. Western blot was used to analyze downstream signaling pathway. We observed that FTY720 inhibits the expression of cleaved caspase-3 and activates both AKT and ERK1/2 pathways. AKT pathway can be blocked by MEK kinase inhibitor PD98059. ERK1/2 pathway can be blocked by the phosphoinositide-3 kinase inhibitor wortmannin. AKT and ERK1/2 activation can also be inhibited by S1P1/3 receptor antagonist VPC23019, Gi antagonist PTX. The protein levels of TNF-α and IL1ß were upregulated during hypoxia/reoxygenation and were attenuated by FTY720. We conclude that FTY720, via its cargo of S1P, can protect cardiomyocytes against hypoxia/reoxygenation injury. This effect is achieved by inhibiting caspase-3 expression, inflammatory cytokine levels and activating AKT and ERK1/2 signaling pathways. The prosurvival signal activation is dependent on S1P1, 3 subtype receptors and Gi protein.
