Abstract
BACKGROUND This study aimed to establish and validate a novel predictive model named integrative inflammatory and nutritional score (IINS) for prognostic prediction in esophageal squamous cell carcinoma (ESCC). MATERIALS AND METHODS We retrospectively recruited 494 pathologically confirmed ESCC patients with surgery and randomized them into training (n = 346) or validation group (n = 148). The least absolute shrinkage and selection operator (LASSO) Cox proportional hazards (PH) regression analysis was initially used to construct a novel predictive model of IINS. The clinical features and prognostic factors with hazard ratio (HRs) and 95% confidence intervals (CIs) grouped by IINS were analyzed. Nomogram was also established to verify the prognostic value of IINS. RESULTS According to the LASSO Cox PH regression analysis, a novel score of IINS was initially constructed based on 10 inflammatory and nutritional indicators with the optimal cut-off level of 2.35. The areas under the curve (AUCs) of IINS regarding prognostic ability in 1-year, 3-years, and 5-years prediction were 0.814 (95% CI: 0.769-0.854), 0.748 (95% CI: 0.698-0.793), and 0.792 (95% CI: 0.745-0.833) in the training cohort and 0.802 (95% CI: 0.733-0.866), 0.702 (95% CI: 0.621-0.774), and 0.748 (95% CI: 0.670-0.816) in the validation cohort, respectively. IINS had the largest AUCs in the two cohorts compared with other prognostic indicators, indicating a higher predictive ability. A better 5-years cancer-specific survival (CSS) was found in patients with IINS ≤ 2.35 compared with those with IINS > 2.35 in both training cohort (54.3% vs. 11.1%, P < 0.001) and validation cohort (53.7% vs. 18.2%, P < 0.001). The IINS was then confirmed as a useful independent factor (training cohort: HR: 3.000, 95% CI: 2.254-3.992, P < 0.001; validation cohort: HR: 2.609, 95% CI: 1.693-4.020, P < 0.001). Finally, an IINS-based predictive nomogram model was established and validated the CSS prediction (training set: C-index = 0.71 and validation set: C-index = 0.69, respectively). CONCLUSION Preoperative IINS is an independent predictor of CSS in ESCC. The nomogram based on IINS may be used as a potential risk stratification to predict individual CSS and guide treatment in ESCC with radical resection.

Abstract
As a direct thin band gap n-type semiconductor, bismuth sulfide (Bi2S3) nanomaterials possess great near-infrared (NIR)-triggered photothermal effects, photoacoustic (PA) and computed tomography (CT) imaging properties. Hence, Bi2S3 nanomaterials have become a research focal point in multiple domains, such as the construction of NIR-triggered nanosystems for cancer therapy. In this study, through a simple one-pot synthesis with the assistance of EDTA-2Na, we first obtained monodispersed spherical Bi2S3 of uniform particle sizes with fascinating photothermal and PA/CT imaging properties. Based on this, we introduced the photosensitizer Ce6 with photodynamic property and CeO2 with the O2-evolving characteristic, and thus designed a core-shell structure of the Bi2S3@Ce6-CeO2 nanocomposites (Bi2S3@Ce6-CeO2 NCs). The as-received Bi2S3@Ce6-CeO2 NCs exhibited a remarkable synergetic photothermal and photodynamic therapeutic effect both in vitro and in vivo, demonstrating its promising potential for cancer treatments. In the long term, the multifunctional PA/CT properties of both Bi2S3 NPs and Bi2S3@Ce6-CeO2 NCs in this study also supply a novel Bi2S3-based platform for constructing integrated diagnosis and treatment platforms.

Abstract
Cancer is a major disease burden worldwide. In recent years, in addition to surgical resection, radiotherapy and chemotherapy are recognized as the most effective methods for treating solid tumors. These methods have been introduced to treat tumors of different origins and stages clinically. However, due to insufficient blood flow and oxygen (O2) supply in solid tumors, hypoxia is caused, leading to decreased sensitivity of tumor cells and poor therapeutic effects. In addition, hypoxia will also lead to resistance to most anticancer drugs, accelerate malignant progress, and increase metastasis. In solid tumors, adequate O2 supply and adequate delivery of anticancer drugs are essential to improve radiotherapy and chemotherapy sensitivity. In recent decades, the researches on relieving tumor hypoxia have attracted researchers' extensive attention and achieved good results. However, as far as we know, there is no detailed review of the researches on alleviating tumor hypoxia. Therefore, in this contribution, we hope to give an overview of the researches on methods to improve tumor hypoxia environment and summarize their effect and application in tumor therapy, to provide a methodological reference for the research and development of new antitumor agents.

Abstract
Cisplatin is a promising therapeutic for the treatment of non-small cell lung cancer (NSCLC). Unfortunately, a significant portion of NSCLC patients relapse due to cisplatin chemoresistance. This chemoresistance is thought to be primarily associated with hypoxia in the tumor microenvironment. Administration of hemoglobin (Hb)-based oxygen (O2) carriers (HBOCs) is a promising strategy to alleviate hypoxia in the tumor, which may make cisplatin more effective. In this study, we administered a high O2 affinity, relaxed state (R-state) polymerized hemoglobin (PolyHb) to three different NSCLC cell lines cultured in vitro and implanted in vivo into healthy mice. The R-state PolyHb administered in this study is unable to deliver O2 unless under severe hypoxia which significantly limits its oxygenation potential. In vitro sensitivity studies indicate that the administration of PolyHb increases the effectiveness of cisplatin under hypoxic conditions. Additional animal studies revealed that co-administration of PolyHb with cisplatin attenuated tumor growth without alleviating hypoxia. Analysis of reactive O2 species production in the presence of hypoxic culture indicates that exogenous ROS production by oxidized PolyHb may the mechanism of chemosensitization. This ROS mechanism, coupled with oxygenation, may be a potential chemosensitizing strategy for use in NSCLC treatment.

Abstract
Biomineralization of biomaterials has shown extraordinary potential in cancer treatment, but the exploration of their in vivo applications is still insufficient. Here, we report a biohybrid microalgae system using a biomineralization approach to improve their biocompatibility, while keeping their living activities for radiation and photodynamic synergistic therapy in breast cancer. The biohybrid algae (Algae@SiO2) synthesized by a one-step biomimetic silicification method could significantly enhance their cytotoxicity and tolerance, improving the living activity in the tumor area. The innate chlorophyll and unique optical property make Algae@SiO2 possess dual imaging ability, namely, photoacoustic imaging and fluorescence imaging. Algae@SiO2 accumulated in tumor sites could generate oxygen in situ by external light-mediated photosynthesis, relieve tumor hypoxia, and then enhance the efficiency of radiation therapy. As a natural photosensitizer, the released chlorophyll from Algae@SiO2 could provide reactive oxygen species to kill the cancer cells for the cascaded photodynamic therapy. The significant suppression of tumor growth in the mice bearing 4T1 tumor successfully demonstrates the promising anti-tumor effect of the Algae@SiO2-mediated synergistic therapy. Our results show that biohybrid algae, integrated with PAI/FI dual imaging, radiosensitization, and cascaded photothermal therapy, is a promising multifunctional efficient biosystem for cancer treatment.

Polymerized human hemoglobin facilitated modulation of tumor oxygenation is dependent on tumor oxygenation status and oxygen affinity of the hemoglobin-based oxygen carrier. Sci Rep 2020; 10:11372. [PMID: 32647211 PMCID: PMC7347553 DOI: 10.1038/s41598-020-68190-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Accepted: 06/17/2020] [Indexed: 12/18/2022] Open
Abstract
Administration of hemoglobin-based oxygen carriers (HBOCs) into the systemic circulation is a potential strategy to relieve solid tumor hypoxia in order to increase the effectiveness of chemotherapeutics. Previous computational analysis indicated that the oxygen (O2) status of the tumor and HBOC O2 affinity may play a role in increased O2 delivery to the tumor. However, no study has experimentally investigated how low- and high-affinity HBOCs would perform in normoxic and hypoxic tumors. In this study, we examined how the HBOC, polymerized human hemoglobin (PolyhHb), in the relaxed (R) or tense (T) quaternary state modulates O2 delivery to hypoxic (FME) and normoxic (LOX) human melanoma xenografts in a murine window chamber model. We examined microcirculatory fluid flow via video shearing optical microscopy, and O2 distributions via phosphorescence quenching microscopy. Additionally, we examined how weekly infusion of a 20% top-load dose of PolyhHb influences growth rate, vascularization, and regional blood flow in the FME and LOX tumor xenografts. Infusion of low-affinity T-state PolyhHb led to increased tissue oxygenation, decreased blood flow, decreased tumor growth, and decreased vascularization in hypoxic tumors. However, infusion of both T-state and R-state PolyhHbs led to worse outcomes in normoxic tumors. Of particular concern was the high-affinity R-state PolyhHb, which led to no improvement in hypoxic tumors and significantly worsened outcomes in normoxic tumors. Taken together, the results of this study indicate that the tumor O2 status is a primary determinant of the potency and outcomes of infused PolyhHb.

Abstract
Oxygen-saturated perfluorohexane-cored, cisplatin (Pt)-decorated hollow gold nanospheres (Pt-HAuNS-PFH@O2) have been synthesized for ultrasound (US) imaging-guided tumor treatment depending on chemo/photothermal therapy, relief of hypoxia, and photothermal induced US contrast signal. Both NIR laser-induced hyperthermia generation by gold nanospheres and acidity triggered release of Pt resulted in high toxicity after internalization by breast cancer cells. According to ex vivo immunofluorescence investigation and in vivo pharmacodynamic studies on MDA-MB-231 tumor bearing mice, the susceptibility of tumors to Pt-HAuNS-PFH@O2 was improved by the relief of hypoxia. In addition, US imaging under different conditions verified the amplified US contrast property of Pt-HAuNS-PFH@O2 by the heat-dependent liquid-gas conversion of PFH. Overall, Pt-HAuNS-PFH@O2 can be promisingly used as an oxygen self-enriched nanoplatform for US imaging-guided chemo/photothermal therapy.

Abstract
Manganese dioxide nanomaterial is a new type of inorganic nanomaterial offering numerous advantages: simple preparation, low cost, and environmental friendliness. This review summarizes the traditional and novel synthetic methods for manganese dioxide nanomaterials and mainly discusses their potential in biomedical applications. Manganese dioxide nanomaterials are mainly used as drug carriers in tumor therapy. In recent years, the construction of multifunctional nano-platforms using manganese dioxide has gradually improved. The main mechanism is that manganese dioxide nanomaterials can combine with reactive oxygen species in the tumor microenvironment to alleviate tumor hypoxia. Manganese dioxide has also been used to quench fluorescent carbon dots in fluorescent probes. Based on the oxidation ability and catalytic activity of MnO2, MnO2 nanosheets are widely used to build biosensors. New research shows that manganese dioxide nanomaterials also have great potential in gene therapy and nuclear magnetic imaging.

Abstract
The therapeutic outcome of chemotherapy is limited, although it is still the preferent strategy for cancer therapy. By regulation of tumor microenvironment and introduction of another therapeutic manner for combination therapy can enhance the anticancer activity of chemotherapeutics. Herein, we have constructed a hybrid nanostructure which composed of manganese dioxide (MnO2) and doxorubicin (DOX) as well as IR780 by stabilizing with BSA (BMDI) in one-pot procedure to alleviate tumor hypoxia and enhance tumor growth inhibition. The MnO2 can react with H2O2 to generate oxygen, and additionally react with GSH to realize tumor microenvironment responsive drug controlled release. And the release Mn ions further enhanced the magnetic resonance signal which made the BMDI a promising contrast agent for MRI. Moreover, the introduction of MnO2 has enhanced the anticancer activity of DOX in vitro and in vivo, and efficiently suppressed the tumor growth. By further introducing with photothermal therapy (PTT), the tumor growth was almost inhibited. It demonstrated that the BMDI hybrid nanostructure has great potential in tumor growth inhibition as therapeutics carrier.

Abstract
Smart drug delivery systems (SDDSs) for cancer treatment are of considerable interest in the field of theranostics. However, developing SDDSs with early diagnostic capability, enhanced drug delivery and efficient biodegradability still remains a scientific challenge. Herein, we report near-infrared light and tumor microenvironment (TME), dual responsive as well as size-switchable nanocapsules. These nanocapsules are made of a PLGA-polymer matrix coated with Fe/FeO core-shell nanocrystals and co-loaded with chemotherapy drug and photothermal agent. Smartly engineered nanocapsules can not only shrink and decompose into small-sized nanodrugs upon drug release but also can regulate the TME to overproduce reactive oxygen species for enhanced synergistic therapy in tumors. In vivo experiments demonstrate that these nanocapsules can target to tumor sites through fluorescence/magnetic resonance imaging and offer remarkable therapeutic results. Our synthetic strategy provides a platform for next generation smart nanocapsules with enhanced permeability and retention effect, multimodal anticancer theranostics, and biodegradability.

Abstract
Developing new strategies to alleviate tumor hypoxia and enhance the therapeutic efficacy towards solid tumors is of great significance to tumor therapy. Herein, to overcome tumor hypoxia, specifically designed aza-BODIPY photosensitizer is co-loaded with anti-cancer drug (doxorubicin, DOX) onto the hydrangea-structured MnO2 nanoparticles, and a tumor microenvironment (TME) responsive degradable nanoplatform (MDSP NP) is established. MDSP NPs (∼54 nm), with near infrared absorption (∼853 nm), can be rapidly dissociated to generate oxygen in response to TME, whereby improving tumor hypoxia, in favor of effective drugs release and enhanced chemo/photodynamic therapy. Revealed by in vivo fluorescence and photoaccoustic imaging, MDSP NPs are preferential accumulated at tumor site. Confirmed by photothermal imaging, MDSP NPs can induce hyperthermia to relieve hypoxia, promote the uptake of therapeutic nanoparticles, and further reduce the resistance and improve the therapeutic efficiency. As a result, a remarkable synergistic tumor chemo/photodynamic/photothermal therapy with hydrangea-structured TME responsive oxygen-self-generation nanoplatform is confirmed by both in vitro and in vivo studies, testifying its great potential for hypoxic tumor treatment in clinical application.

Abstract
Phototherapy is a promising treatment method for cancer therapy. However, the various factors have greatly restricted phototherapy development, including the poor accumulation of photosensitizer in tumor, hypoxia in solid tumor tissue and systemic phototoxicity. Herein, a mitochondrial-targeted multifunctional dye-anchored manganese oxide nanoparticle (IR808@MnO NP) is developed for enhancing phototherapy of cancer. In this nanoplatform, IR808 as a small molecule dye acts as a tumor targeting ligand to make IR808@MnO NPs with capacity to actively target tumor cells and relocate finally in the mitochondria. Meanwhile, continuous production of oxygen (O2 ) and regulation of pH induced by the high reactivity and specificity of MnO NPs toward mitochondrial endogenous hydrogen peroxide (H2 O2 ) could effectively modulate tumor hypoxia and lessen the tumor subacid environment. Large amounts of reactive oxide species (ROS) are generated during the reaction process between H2 O2 and MnO NPs. Furthermore, under laser irradiation, IR808 in IR808@MnO NPs turns O2 into a highly toxic singlet oxygen (1 O2 ) and generates hyperthermia. The results indicate that IR808@MnO NPs have the high efficiency of specific targeting of tumors, relieving tumor subacid environment, improving the tumor hypoxia environment, and generating large amounts of ROS to kill tumor cells. It is expected to have a wide application in treating cancer.

Abstract
The accurate evaluation of the therapeutic effects of advanced laryngeal and hypopharyngeal squamous cell carcinoma (LHSCC) remains challenging. In this study, we determined the value of quantitative parameters derived from dual-energy computed tomography (DECT) for predicting the therapeutic effects of advanced LHSCC and to provide valuable evidence for early judgement of the tumour's response to therapy in clinical practice. We prospectively analysed 41 patients with pathologically confirmed LHSCC. All patients received a DECT scan before therapy. Nineteen of 41 patients showed complete remission (CR), and 22 showed non-complete remission (NCR). The mean of the slope of spectral Hounsfield unit curve (λHU), standardized iodine concentration and effective atomic number in the CR group were significantly lower than the NCR group (P < 0.05). There were no significant differences for T stage, treatment modality and standardized water concentration between two groups (P > 0.05). The best predictor of CR effect was λHU. The 2-year cumulative recurrence rate of patients with higher λHU values was significantly higher than that of patients with lower λHU values (P < 0.05), while the 2-year survival rate of those patients was not significantly different (P > 0.05). DECT could easily identify CR patients and potentially help to choose the appropriate treatment regimen for advanced LHSCC.

Abstract
Ultrasound (US)-triggered sonodynamic therapy (SDT) can solve the critical issue of low tissue-penetrating depth of traditional phototriggered therapies, but the SDT efficacy is still not satisfactorily high in combating cancer at the current stage. Here we report on augmenting the SDT efficacy based on catalytic nanomedicine, which takes the efficient catalytic features of nanoenzymes to modulate the tumor microenvironment (TME). The multifunctional nanosonosensitizers have been successfully constructed by the integration of a MnO x component with biocompatible/biodegradable hollow mesoporous organosilica nanoparticles, followed by conjugation with protoporphyrin (as the sonosensitizer) and cyclic arginine-glycine-aspartic pentapeptide (as the targeting peptide). The MnO x component in the composite nanosonosensitizer acts as an inorganic nanoenzyme for converting the tumor-overexpressed hydrogen peroxide (H2O2) molecules into oxygen and enhancing the tumor oxygen level subsequently, which has been demonstrated to facilitate SDT-induced reactive oxygen species production and enhance SDT efficacy subsequently. The targeted accumulation of these composite nanosonosensitizers efficiently suppressed the growth of U87 tumor xenograft on nude mice after US-triggered SDT treatment. The high in vivo biocompatibility and easy excretion of these multifunctional nanosonosensitizers from the body have also been evaluated and demonstrated to guarantee their future clinical translation, and their TME-responsive T1-weighted magnetic resonance imaging capability provides the potential for therapeutic guidance and monitoring during SDT.

Abstract
Hypoxia in the tumor microenvironment (TME) mediates resistance to radiotherapy and contributes to poor prognosis in patients receiving radiotherapy. Here we report the design of clinically suitable formulations of hybrid manganese dioxide (MnO2) nanoparticles (MDNP) using biocompatible materials to reoxygenate the TME by reacting with endogenous H2O2 MDNP containing hydrophilic terpolymer-protein-MnO2 or hydrophobic polymer-lipid-MnO2 provided different oxygen generation rates in the TME relevant to different clinical settings. In highly hypoxic murine or human xenograft breast tumor models, we found that administering either MDNP formulation before radiotherapy modulated tumor hypoxia and increased radiotherapy efficacy, acting to reduce tumor growth, VEGF expression, and vascular density. MDNP treatment also increased apoptosis and DNA double strand breaks, increasing median host survival 3- to 5-fold. Notably, in the murine model, approximately 40% of tumor-bearing mice were tumor-free after a single treatment with MDNPs plus radiotherapy at a 2.5-fold lower dose than required to achieve the same curative treatment without MDNPs. Overall, our findings offer a preclinical proof of concept for the use of MDNP formulations as effective radiotherapy adjuvants. Cancer Res; 76(22); 6643-56. ©2016 AACR.

Abstract
Hypoxia promotes not only the invasiveness of tumor cells, but also chemoresistance in cancer. Tumor associated macrophages (TAMs) residing at the site of hypoxic region of tumors have been known to cooperate with tumor cells, and promote proliferation and chemoresistance. Therefore, there is an urgent need for new strategies to alleviate tumor hypoxia and enhance chemotherapy response in solid tumors. Herein, we have taken advantage of high accumulation of TAMs in hypoxic regions of tumor and high reactivity of manganese dioxide nanoparticles (MnO2 NPs) toward hydrogen peroxide (H2O2) for the simultaneous production of O2 and regulation of pH to effectively alleviate tumor hypoxia by targeted delivery of MnO2 NPs to the hypoxic area. Furthermore, we also utilized the ability of hyaluronic acid (HA) modification in reprogramming anti-inflammatory, pro-tumoral M2 TAMs to pro-inflammatory, antitumor M1 macrophages to further enhance the ability of MnO2 NPs to lessen tumor hypoxia and modulate chemoresistance. The HA-coated, mannan-conjugated MnO2 particle (Man-HA-MnO2) treatment significantly increased tumor oxygenation and down-regulated hypoxia-inducible factor-1 α (HIF-1α) and vascular endothelial growth factor (VEGF) in the tumor. Combination treatment of the tumors with Man-HA-MnO2 NPs and doxorubicin significantly increased apparent diffusion coefficient (ADC) values of breast tumor, inhibited tumor growth and tumor cell proliferation as compared with chemotherapy alone. In addition, the reaction of Man-HA-MnO2 NPs toward endogenous H2O2 highly enhanced T1- and T2-MRI performance for tumor imaging and detection.

Abstract
Glutaraldehyde-polymerized porcine hemoglobin (pPolyHb) is a hemoglobin-based oxygen carrier currently being developed as a potential red blood cell substitute. We assessed the protective effect of pPolyHb on transient focal cerebral ischemia/reperfusion (I/R) injury. Several outcomes were tested, including infarct size, neurological score, production of inflammatory factors, and markers of oxidative status. Our results show that pPolyHb can not only significantly reduce infarct volume and improve neurological score, but can also inhibit the expression of TNF-α and IL-1β. Furthermore, the generation of MDA and MPO was reduced by pPolyHb. We conclude that pPolyHb has a positive effect on transient focal cerebral I/R injury.

Abstract
Insufficient oxygenation (hypoxia), acidic pH (acidosis), and elevated levels of reactive oxygen species (ROS), such as H2O2, are characteristic abnormalities of the tumor microenvironment (TME). These abnormalities promote tumor aggressiveness, metastasis, and resistance to therapies. To date, there is no treatment available for comprehensive modulation of the TME. Approaches so far have been limited to regulating hypoxia, acidosis, or ROS individually, without accounting for their interdependent effects on tumor progression and response to treatments. Hence we have engineered multifunctional and colloidally stable bioinorganic nanoparticles composed of polyelectrolyte-albumin complex and MnO2 nanoparticles (A-MnO2 NPs) and utilized the reactivity of MnO2 toward peroxides for regulation of the TME with simultaneous oxygen generation and pH increase. In vitro studies showed that these NPs can generate oxygen by reacting with H2O2 produced by cancer cells under hypoxic conditions. A-MnO2 NPs simultaneously increased tumor oxygenation by 45% while increasing tumor pH from pH 6.7 to pH 7.2 by reacting with endogenous H2O2 produced within the tumor in a murine breast tumor model. Intratumoral treatment with NPs also led to the downregulation of two major regulators in tumor progression and aggressiveness, that is, hypoxia-inducible factor-1 alpha and vascular endothelial growth factor in the tumor. Combination treatment of the tumors with NPs and ionizing radiation significantly inhibited breast tumor growth, increased DNA double strand breaks and cancer cell death as compared to radiation therapy alone. These results suggest great potential of A-MnO2 NPs for modulation of the TME and enhancement of radiation response in the treatment of cancer.

Abstract
This study was to investigate whether glutaraldehyde-polymerized human placenta hemoglobin (PolyPHb) could attenuate ischemia/reperfusion (I/R)-induced liver injury. Isovolemic hemodilution of SD rats was performed by exchanging 15% total blood volume with PolyPHb. I/R was induced by left liver lobes pedicle cross-clamping for 60 min and reperfusion for 2 h. Blood pressure moderately elevated after PolyPHb infusion and returned to basal level within 10 min. The hepatic histopathological damage and the activities of liver injury markers were reduced by PolyPHb. The TUNEL staining and caspase assay indicated hepatic apoptosis was also inhibited. Therefore, our findings suggest PolyPHb can reduce liver I/R injury.

Abstract
The goal of this study was to investigate whether hemoglobin-based oxygen carrier (HBOC) attenuated ischemia/reperfusion (I/R)-induced kidney injury. Male SD rats were randomly divided into a sham group, I/R group, and HBOC group (injection of 0.1 gHb/kg PolyPHb). The ischemia was induced by bilateral renal pedicle cross-clamping for 45min. Then the clamp was released to allow 24h reperfusion. Without increasing blood pressure, PolyPHb reduced the blood urea nitrogen and creatinine in plasma and attenuated the tumor necrosis factor-α and interleukin-8 in kidney tissue. Therefore, our findings suggest that PolyPHb could reduce kidney injury after I/R injury, and this effect was probably associated with the depressed inflammatory response.

Abstract
This study was designed to investigate whether polymerized human placenta hemoglobin (PolyPHb) attenuated hemorrhagic shock-induced lung injury. A mean arterial pressure (MAP) of 30mmHg was maintained for 60 min. Then, all the rats were randomly resuscitated with hetastarch, whole blood, or PolyPHb. The result indicated that PolyPHb greatly improved the MAP and pulmonary function, and significantly reduced the release of inflammatory cytokines, histopathological changes, and pulmonary edema. Therefore, our findings suggest that PolyPHb could reduce pulmonary injury after hemorrhagic shock, and this effect was probably associated with the depressed inflammatory response.

Abstract
This study was to investigate whether polymerized human placenta hemoglobin (PolyPHb) given before ischemia protects in vivo rat heart function against ischemia/reperfusion (I/R) injury. Forty-five male Sprague-Dawley rats were randomly divided (n = 15 per group) into a sham group, control group (pretreatment with Lactated Ringer's solution), or PolyPHb group (pretreatment with 0.1 gHb/kg PolyPHb). Rat hearts were subjected to 30-min ischemia by occlusion of left anterior descending, followed by 2-hr reperfusion. As compared to the control group, PolyPHb preserved cardiac function and reduced cardiac troponin-I release and histopathological changes. Therefore, PolyPHb pretreatment provided a profound cardioprotective effect on the in vivo rat heart.

Abstract
OBJECTIVES The etiology of myocardial ischemia/reperfusion (I/R) injury is multifactorial, but activation of the innate immune system and the resulting inflammatory response are important components of I/R injury. The aim of this study was to investigate the protective effect of a hemoglobin-based oxygen carrier (HBOC) on cold I/R heart and to explore the underlying mechanisms. METHODS Isolated Sprague-Dawley rat hearts were perfused in the Langendorff mode. After 30 min of basal perfusion, rat hearts were arrested with histidine-tryptophan-ketoglutarate solution (HTKs) with or without an HBOC and hypothermically stored (4°C) for 9 or 14 h, followed by 2 h of reperfusion. RESULTS Compared with HTKs alone, the HBOC in HTKs greatly improved heart contraction and decreased infarct size, necrosis and apoptosis, which was related to the reduced expression of Toll-like receptor 2 (TLR 2), TLR 4, TNF-α, IL-1β and nuclear factor-κB (NF-κB) activation. CONCLUSIONS Our results demonstrated that the HBOC protected isolated rat heart from cold I/R injury and this protection was associated with attenuation of the expression of the TLR 2 and TLR 4/NF-κB signaling pathway, which may down-regulate the inflammatory response.

Abstract
Ischaemia/reperfusion (I/R) injury is harmful to the cardiovascular system and is responsible for the inflammatory response, which, in turn, aggravates cardiac dysfunction. This study was designed to investigate the protective effect and potential mechanism of a haemoglobin-based oxygen carrier on cold I/R-injured hearts. Isolated Sprague-Dawley rat hearts were perfused in Langendorff mode. After a 30-min basal perfusion, rat hearts were arrested and hypothermically stored at 4°C for 12h followed by a 2-h reperfusion. Compared with histidine-tryptophan-ketoglutarate solution (HTKs), polymerised placenta haemoglobin (PolyPHb) in HTKs greatly improved heart contraction and decreased infarction size, necrosis, and apoptosis, which was related to reduced expression of TLR2, TLR4, TNF-α, and IL-1β, and NF-κB activation. Our results demonstrate the cardioprotective effect of PolyPHb on cold I/R-injured hearts and revealed that this protection was mediated in large part by attenuation of TLR2 and -4/NF-κB signalling pathway and could possibly down-regulate the inflammatory response.

Abstract
This study was designed to investigate whether polymerized human placenta hemoglobin (PolyPHb) pretreatment provided protection to the heart after ischemia/reperfusion (I/R) injury. After 10-min basal perfusion, isolated Sprague-Dawley rat hearts were pretreated with 0.1 gHb/dL PolyPHb and subjected to I/R injury. PolyPHb pretreatment greatly reduced the decreases in left ventricular developed pressure (LVDP), maximum LVDP increase and decrease rate (+/-dp/dt), and the increase in left ventricular end-diastolic pressure (LVEDP) as compared to the control group. Moreover, the myocardial infarction and troponin-I release were significantly reduced in the pre-HBOCs group. Therefore, PolyPHb pretreatment was protective to the isolated I/R heart.

Abstract
This study was designed to investigate the influence of polymerized human placenta hemoglobin (PolyPHb) pretreatment on ischemia/reperfusion (I/R) injury-induced myocardial apoptosis. Isolated Sprague-Dawley rat hearts were perfused by Langendorff model. After basal perfusion, hearts were arrested by St.Thomas' solution (STS) with (Pre-HBOC group) or without PolyPHb (STS group), then subjected to I/R injury. Our results showed that PolyPHb pretreatment greatly reduced the TUNEL-positive myocardial cells and decreased the caspase-3 activity and cleavage, which was further confirmed by the linear regression analysis. Therefore, PolyPHb pretreatment was beneficial to attenuation of myocardial apoptosis and provided protection to the heart against I/R injury.
