RESUMO

We investigated whether mild hypothermia combined with sodium hydrosulfide treatment during resuscitation improves neuron survival following cerebral ischemia-reperfusion injury beyond that observed for the individual treatments. Male Sprague-Dawley rats were divided into seven groups (n = 20 for each group). All rats underwent Pulsinelli 4-vessel occlusion. Ischemia was induced for 15 min using ligatures around the common carotid arteries, except for the sham group. Immediately after initiating reperfusion, the mild hypothermia (MH), sodium hydrosulfide (NaHS), hydroxylamine (HA), MH + NaHS, MH + HA, and ischemia-reperfusion (I/R) control groups received an intraperitoneal injection of saline, sodium hydrosulfide, hydroxylamine, sodium hydrosulfide, hydroxylamine, and saline, respectively, and mild hypothermia (32 to 33 °C) was induced in the MH, MH + NaHS, and MH + HA groups for 6 h. The levels of NR2A, NR2B, p-Akt, and p-Gsk-3ß in the hippocampus of the MH, NaHS, and MH + NaHS groups were higher than those in the I/R control group, with the highest levels observed in the MH + NaHS group (P < 0.05). Treatment with hydroxylamine reduced the levels of these proteins in the HA and MH + HA groups, compared with the I/R control and MH groups, respectively. The apoptotic index of the CA1 region of the hippocampus was 45.2, 66.5, 63.5, and 84.8 % in the MH + NaHS, MH, NaHS, and I/R control groups, respectively (P < 0.05), indicating that the combination treatment shifted the NR2A/NR2B balance in favor of synaptic neuron stimulation and phosphatidylinositol 3'-kinase (PI3K)/Akt signaling. The combination of mild hypothermia and sodium hydrosulfide treatment for resuscitation following ischemia-reperfusion injury was more beneficial for reducing hippocampal apoptosis and pathology than that of mild hypothermia or hydrogen sulfide treatment alone.

RESUMO

Seawater drowning-induced acute lung injury (ALI) is a serious clinical condition characterized by increased alveolar-capillary permeability, excessive inflammatory responses, and refractory hypoxemia. However, current therapeutic options are largely supportive; thus, it is of great interest to search for alternative agents to treat seawater aspiration-induced ALI. Erythropoietin (EPO) is a multifunctional agent with antiinflammatory, antioxidative, and antiapoptotic properties. However, the effects of EPO on seawater aspiration-induced ALI remain unclear. In the present study, male rats were randomly assigned to the naive group, normal saline group, seawater group, or seawater + EPO group. EPO was administered intraperitoneally at 48 and 24 h before seawater aspiration. Arterial blood gas analysis was performed with a gas analyzer at baseline, 30 min, 1 h, 4 h, and 24 h after seawater aspiration, respectively. Histological scores, computed tomography scan, nuclear factor kappa B p65, inducible nitric oxide synthase, caspase-3, tumor necrosis factor-alpha, interleukin (IL)-1ß, IL-6, IL-10, wet-to-dry weight ratio, myeloperoxidase activity, malondialdehyde, and superoxide dismutase in the lung were determined 30 min after seawater aspiration. Our results showed that EPO pretreatment alleviated seawater aspiration-induced ALI, as indicated by increased arterial partial oxygen tension and decreased lung histological scores. Furthermore, EPO pretreatment attenuated seawater aspiration-induced increase in the expressions of pulmonary nuclear factor kappa B p65, inducible nitric oxide synthase, caspase-3, tumor necrosis factor-alpha, IL-1ß, myeloperoxidase activity, and malondialdehyde when compared with the seawater group. Collectively, our study suggested that EPO pretreatment attenuates seawater aspiration-induced ALI by down-regulation of pulmonary pro-inflammatory cytokines, oxidative stress, and apoptosis.

RESUMO

BACKGROUND: Both hydrogen sulphide (H2S) and mild hypothermia have been reported to prevent brain damage caused by reperfusion assault through regulating the N-methyl-D-aspartate receptor (NMDAR). However, the relationship between the two treatments and how they exert neuro-protective effects through NMDARs remain to be elucidated. METHODS: Transient cerebral ischemia was induced using the Pulsinelli four-vessel occlusion method. We used sodium hydrosulphide (NaHS) as the H2S donor. We randomly divided 100 Sprague-Dawley rats into five groups of 20: Sham operation group (Sh), normothermic (36-37 °C) ischemia group (NT), mild hypothermic (32-33 °C) ischemia group (mHT), normothermic ischemia combined with NaHS treatment group (NT + NaHS), and mild hypothermic ischemia combined with NaHS treatment group (mHT + NaHS). After 6 hrs of reperfusion, rats were decapitated and hippocampus samples were immediately collected. We measured NR2A (GluN1), NR2B (GluN2) and p-CREB protein levels using western blotting. We further analyzed BDNF mRNA expression by real-time PCR. Hematoxylin and eosin (HE) staining was used to examine pyramidal cell histology at the CA1 region. All statistical analyses were carried out by ANOVA and LSD t-test as implemented by the SPSS 13.0 software. RESULTS: In the four test groups with ischemia-reperfusion, hippocampal H2S concentration increased following treatment, and administration of NaHS further increased H2S levels. Moreover, administration of both NaHS and mild hypothermia resulted in up-regulation of NR2A and NR2B protein expressions, as well as p-CREB protein and BDNF mRNA levels. At the cellular level, NaHS and mild hypothermia groups exhibited lower damage caused by ischemia-reperfusion in the CA1 region of the hippocampus. The strongest protective effect was observed in rats treated with combined NaHS and mild hypothermia, suggesting their effects were additive. CONCLUSION: Our results support previous findings that hydrogen sulphide and mild hypothermia can prevent ischemia-reperfusion injury. Both treatments caused an up-regulation of NMDA receptors, as well as an elevation in p-CREB protein and BDNF mRNA levels. Thus, hydrogen sulphide and mild hypothermia may provide neuro-protective effect through activating the pro-survival CREB signaling pathway.

RESUMO

Sepsis-associated encephalopathy (SAE) is a frequent complication in critically ill patients and is associated with long-term cognitive impairments. However, the pathophysiology underlying SAE is poorly understood and the pharmacologic treatment is lacking. The purpose of the present study was to investigate the effects of erythropoietin (EPO) on cognitive impairments in an animal model of SAE induced by peripheral administration of lipopolysaccharide (LPS). Mice were randomly divided into the sham + vehicle, sham + EPO, LPS + vehicle, and LPS + EPO groups. EPO was administrated 30 min after the LPS administration and daily afterward for 2 days. Behavioral tests were performed on days 6 and 7 with open field and fear conditioning tests, respectively. The survival rate was estimated by the Kaplan-Meier method. The levels of proinflammatory responses, oxidative stress, and apoptosis-related markers were measured in the hippocampus at the indicated time points. The synaptic morphometry changes in the CA1 region were observed with transmission electron microscopy. Our results showed that LPS administration resulted in high mortality rate and cognitive impairments, which were accompanied by increased expressions of interleukin-1ß, malondialdehyde, cleaved caspase-3, and abnormal synaptic morphometry changes in the hippocampus. Notably, EPO treatment reversed the cognitive impairments and rescued the brain pathology induced by LPS administration. In conclusion, our data suggested that treatment with EPO reduced the mortality rate and ameliorated cognitive impairments in an animal model of SAE.

RESUMO

Sevoflurane, a commonly used inhaled anesthetic, can induce neuronal apoptosis in the developing rodent brain and correlate with functional neurological impairment later in life. However, the mechanisms underlying these deleterious effects of sevoflurane remain unclear and no effective treatment is currently available. Herein, the authors investigated whether curcumin can prevent the sevoflurane anesthesia-induced cognitive impairment in mice. Six-day-old C57BL/6 mice were exposed to 3% sevoflurane 2h daily for 3 consecutive days and were treated with curcumin at the dose of 20 mg/kg or vehicle 30 min before the sevoflurane anesthesia from postnatal days 6 (P6) to P8. Cognitive functions were evaluated by open field, Morris water maze, and fear conditioning tests on P61, P63-69, and P77-78, respectively. In another separate experiment, mice were killed on day P8 or P78, and the brain tissues were harvested and then subjected to biochemistry studies. Our results showed that repeated neonatal sevoflurane exposure led to significant cognitive impairment later in life, which was associated with increased neuronal apoptosis, neuroinflammation, oxidative nitrosative stress, and decreased memory related proteins. By contrast, pre-administration of curcumin ameliorated early neuronal apoptosis, neuroinflammation, oxidative nitrosative stress, memory related proteins, and later cognitive dysfunction. In conclusion, our data suggested that curcumin pre-administration can prevent the sevoflurane exposure-induced cognitive impairment later in life, which may be partly attributed to its ability to attenuate the neural apoptosis, inflammation, and oxidative nitrosative stress in mouse brain.

RESUMO

Few studies have examined the association between perioperative blood transfusion and postoperative delirium (POD) in aged patients undergoing total hip replacement surgery. In this prospective study, 186 patients older than 65 years undergoing elective unilateral total hip replacement surgery were enrolled. Of those, 94 patients were randomly assigned to the restrictive strategy transfusion strategy group, in which red blood cells were transfused in order to maintain 10.0 g/dL>hemoglobin≧8.0 g/dL. Ninety-two patients were randomly assigned to the liberal transfusion strategy group, in which red blood cells were transfused in order to maintain hemoglobin≧10.0 g/dL. POD was diagnosed by confusion assessment method. The baseline characteristics of patients, the length of hospital stay, the incidence of POD, myocardial infarction, stroke, wound infection, pulmonary embolism, and the transfusion volume were recorded. No difference was observed in the baseline characteristics, the length of hospital stay, and the incidence of POD, myocardial infarction, stroke, wound infection, and pulmonary embolism between the two groups (P>0.05). The proportion of patients transfused with red blood cell and frozen plasma was decreased in the restrictive transfusion group compared with the liberal transfusion group (P<0.05). In conclusion, restrictive transfusion does not influence the incidence of POD but reduces blood transfusion. Thus, restrictive transfusion may serve as an effective and safe strategy for aged patients following total hip replacement.

RESUMO

INTRODUCTION: Accumulating evidence suggests that enhanced inflammatory responses contribute to the pathogenesis of postoperative cognitive dysfunction (POCD). Blood transfusion can trigger an enhancement of acute inflammatory responses. Therefore, we hypothesized that perioperative blood transfusion is associated with a higher risk of POCD in aged patients following total hip replacement surgery. MATERIAL AND METHODS: Patients older than 65 years undergoing elective total hip replacement surgery were enrolled from October 2011 to December 2012. Neurocognitive tests were evaluated at baseline and at 7 d after surgery by a Mini-Mental State Test. Multivariate logistic regression analysis was used to determine risk factors associated with POCD. RESULTS: Fifty-six patients (27.3%) developed POCD 7 d postoperatively. Patients who developed POCD were older, had a lower education level and preoperative hemoglobin concentration, had more blood loss, and had a lower body weight (p < 0.05). Patients with POCD were more likely to receive red blood cells (RBCs) transfusion (51.8% versus 31.5%; p < 0.05). A multivariable logistic regression model identified older age, lower education level, and perioperative blood transfusion of more than 3 units as independent risk factors for POCD 7 d postoperatively. CONCLUSION: Our data suggested that perioperative blood transfusion of more than 3 units of RBCs is an independent risk factor for POCD in aged patients following total hip replacement surgery.

RESUMO

The present study aimed to find whether PROX1 is expressed in small cell lung cancer (SCLC) cell lines, and whether PROX1 knockdown with shRNA via lentivirus resulted in decreased cell proliferation. SCLC cell lines H69, H82, H187 and H889 were selected for the study. PROX1 mRNA and protein levels were determined with real-time reverse-transcription polymerase chain reaction(RT-PCR) and western blot, respectively. The localization and distribution of PROX1 was mapped by immunocytochemistry with a specific antibody. Three pairs of shRNA were selected from a pool of shRNA pairs, and packaged into lentivirus particles to infect the above cell lines. The non-target sequence (NT) and a house-keeping gene, glyceraldehyde 3 phosphate dehydrogenase (GAPDH), were employed as controls. SCLC cell proliferation rates were measured with bromine deoxyuridine (BrdU) incorporation method. The results indicated levels of that PROX1 mRNA were detected in SCLC cell lines in the following rank order H69>H889>H187>H82. A similar profile for PROX1 protein expression was captured. The majority of PROX1 was concentrated at the cell nucleus. H69 was selected to represent the above SCLC cell lines. The PROX1 level in H69 cells was successfully reduced with shRNA lentivirus, and the cell proliferation rate of infected H69 cells was dramatically reduced by 20-50%. Hence, it is concluded that PROX1 expression in SCLC cell line is high, and can be reduced with shRNA lentivirus, thereby reducing the cell proliferation rate.

RESUMO

Valproic acid (VPA) has been shown to exert anti-inflammatory and antioxidant effects in a range of diseases including septic shock. However, the effects of VPA on lipopolysaccharide (LPS)-induced acute lung injury (ALI) remains not well understood. We found that VPA pretreatment attenuated the LPS-induced ALI, as evidenced by the reduced histological scores, myeloperoxidase activity, and wet-to-dry weight ratio in the lung tissues. This was accompanied by the downregulated nuclear factor kappa B (NF-κB) p65, nitric oxide, and inducible nitric oxide synthase in the lung tissues and the decreased levels of tumor necrosis factor alpha and interleukin-1ß in the bronchoalveolar lavage fluid. Furthermore, VPA reduced the nuclear histone deacetylase (HDAC)3 expression whereas increased the cytoplasmic HDAC3 expression. Our results suggested that VPA attenuates the LPS-induced ALI via inhibiting the NF-κB activation probably through a mechanism depending on HDAC3 redistribution.

RESUMO

BACKGROUND: The potential immunosuppressant effects of opioids might have clinical implications. The effects of endomorphins (EMs) and ohmefentanyl (OMF) on cultured rat peritoneal macrophages remain unclear. OBJECTIVE: The aim of this study was to investigate the immunosuppressant effects of EMs and OMF on cultured rat peritoneal macrophages in vitro. METHODS: Purified rat peritoneal macrophages, from healthy adult male Sprague-Dawley rats, were cultured with EM-1 (EM-1 group), EM-2 (EM-2 group), OMF (OMF group), and saline (saline group). We measured the concentrations of tumor necrosis factor (TNF)-α and interleukin (IL)-ß in supernatant when macrophages were cultured with 10(-6) mol/L of EM-1, EM-2, OMF, or saline for 0, 6, 12, and 24 hours (time-effect relationship) or with 10(-10), 10(-9), 10(-8), 10(-7), and 10(-6) mol/L of these substances for 24 hours (concentration-effect relationship). We also determined the phagocytic and bactericidal activities of macrophages using isotope markers when macrophages were cultured with 10(-6) mol/L of EM-1, EM-2, OMF, or saline for 24 hours. RESULTS: Compared with the saline group, TNF-α concentration decreased significantly in the OMF, EM-2, and EM-1 groups at 12 hours (P < 0.05, P < 0.05, and P < 0.01, respectively) and at 24 hours (P < 0.05, P < 0.01, and P < 0.01, respectively). Compared with the saline group, IL-1ß concentration decreased signifcantly in the OMF, EM-2, and EM-1 groups at 12 hours (P < 0.05, P < 0.05, and P < 0.01, respectively) and at 24 hours (P < 0.05, P < 0.01, and P < 0.01, respectively). Decreased TNF-α and IL-1ß concentrations were observed in the supernatant at 24 hours when cultured with 10(-8), 10(-7), and 10(-6) mol/L in the OMF and EM-2 groups (all, P < 0.05) and in the EM-1 group (all, P < 0.01). Compared with the saline group, macrophage phagocytic activity (all, P < 0.05) and macrophage bactericidal activity (all, P < 0.01) were significantly lower in the 3 experimental groups compared with the saline group. CONCLUSION: In this in vitro experiment, EM-1, EM-2, and OMF inhibited the immunosuppressant function of cultured rat peritoneal macrophages, including decreasing TNF-α and IL-1ß concentrations and phagocytic and bactericidal activities.

RESUMO

OBJECTIVE: To investigate the safety and efficacy of fast track surgery (FTS) management in gastric cancer undergoing D2 gastrectomy. METHODS: Eighty gastric cancer patients undergoing D2 gastrectomy were recruited prospectively. Patients were assigned to receive FTS management (n = 40) or conventional perioperative care (n = 40). The FTS care included shorten preoperative fasting time, no nasogastric decompressing tubes and abdominal drainage placed, early postoperative oral feeding, multimodal analgesia, and early mobilisation. The length of postoperative hospital stay, medical cost, nutritional status, gut function, and postoperative complications in the two groups were recorded and compared. RESULTS: FTS group was associated with a significantly shorter postoperative hospital stay compared with conventional care group [(5.6 +/- 1.3) d vs. (9.4 +/- 1.9) d, P < 0.05]. Medical cost was less [(18 620 +/- 2360) Yuan vs. (20 370 +/- 2440) Yuan, P < 0.05] and duration of intravenous infusion [(3.5 +/- 1.4) d vs. (5.8 +/- 1.9) d, P < 0.05] was also shorter. First passage of flatus was earlier in FTS group than in conventional care group [(4.3 +/- 0.4) d vs. (5.5 +/- 0.9) d, P < 0.05]. Loss of body weight in the postoperative period was less in FTS group [(3.2 +/- 0.8) kg vs. (4.3 +/- 1.6) kg, P < 0.05]. There was no difference in morbidity or mortality between the two groups. CONCLUSION: FTS in D2 gastrectomy is safe and efficient, and it can shorten postoperative hospital stay and hasten return of gut function.
