Abstract
Background: The first-line treatment for lung cancer is surgical resection, and one-lung ventilation (OLV) is the most basic anesthetic management method in lung surgery. During OLV, inflammatory cytokines are released in response to the lung tissue damage and promote local and contralateral lung damage through the systemic circulation. We designed a randomized, prospective study to evaluate the effect of the urinary trypsin inhibitor (UTI) ulinastatin on the inflammatory response after video-assisted thoracic lobectomy in patients with lung cancer. Methods: Adult patients aged 19 to 70 years, who were scheduled for video-assisted thoracic lobectomy surgery to treat lung cancer between May 2020 and August 2020, were enrolled in this randomized, prospective study. UTI (300,000 units) mixed with 100 mL of normal saline in the ulinastatin group and 100 mL of normal saline in the control group was administered over 1 h after inducing anesthesia. Results: The baseline (T0) interferon-γ (IFN-γ)/interleukin-4 (IL-4) ratio was not different between the groups (6941.3 ± 2778.7 vs. 6954.3 ± 2752.4 pg/mL, respectively; P > 0.05). The IFN-γ/IL-4 ratio was significantly higher in ulinastatin group at 30 min after entering the recovery room than control group (20,148.2 ± 5054.3 vs. 6674.0 ± 2963.6, respectively; adjusted P < 0.017). Conclusion: Administering UTI attenuated the anti-inflammatory response, in terms of INF-γ expression and the IFN-γ/IL-4 ratio, after video-assisted thoracic surgery in lung cancer patients.

Abstract
Protamine causes cardiac depression, which may be mediated by tumor necrosis factor alpha (TNF-α). Ulinastatin, a human urinary protease inhibitor, inhibits TNF-α. Here, we aimed to investigate whether ulinastatin prevented protamine-induced myocardial depression by inhibiting TNF-α. Rat hearts were perfused using a Langendorff system, and three protocols were followed. Protocol 1: The hearts were divided into saline, ulinastatin-low, and ulinastatin-high groups. Protamine was administered to each group, and myocardial contractility was the primary outcome. Protocol 2: The hearts were allotted to saline or ulinastatin group. Protamine was administered to each group. TNF-α expression in the coronary effluent and myocardial tissue was measured. Protocol 3: The hearts were allotted to saline and ulinastatin groups. Recombinant rat-TNF-α was administered to each group. Protamine alone reduced the maximum left ventricular pressure derivative (LV dP/dt max) by 45 ± 4%. In contrast, the reduction in LV dP/dt max was 4 ± 3% in the ulinastatin-high group. Compared with that in the saline group, the increase in TNF-α in the coronary effluent was attenuated in the ulinastatin group. Recombinant TNF-α alone reduced LV dP/dt max (- 21 ± 14%). In contrast, when TNF-α was added in the presence of ulinastatin, the decrease in LV dP/dt max was prevented significantly (- 3 ± 8%). We showed, for the first time, that ulinastatin protected against protamine-induced myocardial damage, both by inhibiting TNF-α synthesis and by directly preventing the cardiodepressant action of TNF-α.

Abstract
BACKGROUND Administration of ulinastatin was proved to protect many organs from ischemia/reperfusion (I/R) induced injury, yet its protective effects on renal I/R injury under cold condition and mechanism still remain unclear. AIMS In the present study, the protective effects of ulinastatin on renal cold I/R injury as well as its mechanism were investigated. METHODS AND RESULTS Renal cold I/R model was constructed via cross-clamping of left renal artery and vein at 4 °C. The ulinastatin was administrated and multi-methods were performed to evaluate the protective effects. The results showed that ulinastatin could mitigate the renal cold I/R injury. In addition, the attenuated kidney cold I/R injury by ulinastatin was also accompanied with its regulating capability of the microenvironment, such as decreased acute inflammatory response, oxidative stress damage and apoptosis, as well as attenuation of vasculature levels decrease, as evidence by reduced TNF-α, IL-6 mRNA expression, MDA levels and apoptosis, higher levels of SOD activity and CD31/α-SMA expression. CONCLUSION The present study suggested that ulinastatin might be clinically useful in reducing preservation injury induced by cold I/R during renal transplantation surgery.

Abstract
The aim of this study was to investigate whether ulinastatin (UTL) has protective effects on perioperative proinflammatory cytokines and lung injury in cardiopulmonary bypass (CPB) patients. The study included 60 patients undergoing CPB who were randomly divided into a UTL group and a control group. Blood routine examination and inflammatory cytokines concentrations were detected after anesthetic induction (T1), immediately after aortic valve opening (T2), and 4 (T3) and 24 (T4) hours after weaning from CPB. Flow cytometry was used to detect TLR4 and HSP70 expressions. Arterial blood gas and respiratory function were analyzed at the same time points. Compared with the control group, the levels of IL-2, IL-8, TNF-α, NE, TLR4, PA - aDO2, and RI at T2 were significantly lower, whereas HSP70, PaO2, OI, Cd, and Cs were higher in the UTL group (all P < 0.05). Relative to the control group at T3, white blood cell count, TLR4, IL-2, IL-6, IL-8, TNF-α, NE, and RI decreased significantly, whereas IL-10, HSP70, PaO2, OI, and Cs increased in the UTL group (all P < 0.05). At T4, IL-2, IL-6, IL-8, TNF-α, TLR4, and PaCO2 in the UTL group were significantly lower, and PaO2, IL-10, HSP70, and Cs were higher than in the control group (all P < 0.05). Our data show strong evidence that UTL suppresses proinflammatory cytokine elevation and upregulates release of anti-inflammatory mediators, reducing pulmonary injury and improving pulmonary function after CPB.

Abstract
Aim Continuous regional arterial infusion (CRAI) of protease inhibitors may be effective in the treatment of severe acute pancreatitis (SAP), but it is more invasive than i.v. infusion. The purpose of this study was to examine the effectiveness of continuous i.v. infusion (CIVI) for SAP compared with CRAI by unifying the dose and the administration period of nafamostat mesylate. Methods This study comprised 32 patients with SAP who were divided into two groups: the CRAI group and the CIVI group. The protease inhibitor, nafamostat mesylate, was continuously infused at a rate of 200 mg/day for 5 days in both groups. Clinical outcomes including in-hospital mortality were examined. Results There were no significant between-group differences in in-hospital mortality and 90-day mortality. The duration from admission to treatment was significantly shorter in the CIVI group (median, 7 h vs. 2 h, P = 0.0001; CRAI group vs. CIVI group). The rate of mechanical ventilation was significantly less in the CIVI group than in the CRAI group (93% vs. 47%, P = 0.007). The CIVI group showed a tendency toward decreased length of intensive care unit stay (median, 13 days vs. 4 days, P = 0.085) and hospital stay (median, 19 days vs. 11 days, P = 0.072). Total costs during hospitalization were significantly lower in the CIVI group (median, $18,320 vs. $11,641, P = 0.049). Conclusion The effectiveness of CIVI with early nafamostat mesylate treatment after the development of SAP could be equivalent to, or better than, that of CRAI.

Neuroprotective Effect of Ulinastatin on Spinal Cord Ischemia-Reperfusion Injury in Rabbits. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:624819.

Abstract
Ulinastatin (UTI), a trypsin inhibitor, is isolated and purified from human urine and has been shown to exert protective effect on myocardial ischemia reperfusion injury in patients. The present study was aimed at investigating the effect of ulinastatin on neurologic functions after spinal cord ischemia reperfusion injury and the underlying mechanism. The spinal cord IR model was achieved by occluding the aorta just caudal to the left renal artery with a bulldog clamp. The drugs were administered immediately after the clamp was removed. The animals were terminated 48 hours after reperfusion. Neuronal function was evaluated with the Tarlov Scoring System. Spinal cord segments between L2 and L5 were harvested for pathological and biochemical analysis. Ulinastatin administration significantly improved postischemic neurologic function with concomitant reduction of apoptotic cell death. In addition, ulinastatin treatment increased SOD activity and decreased MDA content in the spinal cord tissue. Also, ulinastatin treatment suppressed the protein expressions of Bax and caspase-3 but enhanced Bcl-2 protein expression. These results suggest that ulinastatin significantly attenuates spinal cord ischemia-reperfusion injury and improves postischemic neuronal function and that this protection might be attributable to its antioxidant and antiapoptotic properties.

Abstract
The aim of the present study was to determine the effects of ulinastatin (UTI) on brain injury in rats subjected to cardiopulmonary resuscitation (CPR) following asphyxial cardiac arrest (CA) and identify the underlying mechanisms. In total, 100 healthy male Wistar rats were randomly divided into control and treatment groups (n=50). After 4 min of asphyxial CA, all the rats were immediately subjected to CPR. The treatment group animals were administered 15 mg/kg UTI at the onset of resuscitation. The mortality rate in the two groups was recorded at 24 h post-resuscitation. In addition, neurological function was evaluated at 24, 48 and 72 h post-resuscitation using a neurological deficit scale (NDS). Furthermore, the effects of UTI on the Toll-like receptor 4 (TLR4) signaling pathway in brain tissues were determined by assessing TLR4 mRNA expression, nuclear factor (NF)-κB activity and tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels at 1, 3, 6, 12, 24, 48 and 72 h post-resuscitation. After 24 h, the mortality rate significantly decreased in the treatment group when compared with the control animals (10 vs. 30%; P<0.05). Additionally, an overt improvement was observed in the NDS score following UTI treatment when compared with the control (P<0.01). Finally, statistically significant decreases in the levels of TLR4 mRNA expression, NF-κB activity and TNF-α and IL-6 were observed in the treatment group at each time point (P<0.01). Therefore, UTI treatment at the onset of CPR significantly inhibits the TLR4 signaling pathway, thereby alleviating the inflammatory responses following resuscitation and improving neurological function.

Abstract
Multiple sclerosis (MS) is a common inflammatory and demyelinating neurological disease. Experimental autoimmune encephalomyelitis (EAE), an animal model of MS, has been widely used to test MS treatment methods. Ulinastatin (UTI), a drug used to treat acute inflammatory disorders, has been tested in animal models of autoimmune inflammatory diseases, such as ulcerative colitis and crescentic glomerulonephritis. We recently found that UTI has a neuroprotective effect on EAE by reducing oligodendrocyte apoptosis and demyelination. The anti-inflammatory effects of UTI on EAE/MS, however, have never been investigated. We have therefore evaluated the anti-inflammatory effects of UTI in EAE and explored the mechanisms underlying this effect. EAE was induced in mice with and without UTI treatment. Inflammation and demyelination of spinal cords were evaluated by staining with hematoxylin and eosin and with Luxol fast blue, respectively. Inflammatory markers in serum were analyzed by the Luminex method, and spinal cords were evaluated by immunofluorescence and Western blotting. UTI significantly lowered the clinical and pathological scores and the serum concentrations of the inflammatory cytokines interleukin (IL)-1β, IL-6, and matrix metal protease-9 (MMP-9). UTI also reduced the expression of tumor necrosis factor-alpha (TNF-α)/nuclear factor kappaB (NF-κB)/inducible nitric oxide synthase (iNOS) proteins and decreased CD11b(+) cells in spinal cord lesions. UTI may protect against EAE in mice by suppressing inflammatory responses. We think that UTI might be a potential therapeutic agent for MS.

Abstract
We evaluate the efficacy of urinary trypsin inhibitor (UTI) on inflammation, oxidative stress, hypoxemia, and diseased lesion in a rat model of acute lung injury induced by blunt trauma. Rats were allocated to 4 groups. One group served as normal control. The other 3 groups had a moderate pulmonary contusion. Except for 1 sham group administrated saline, 1 group was administrated low-dose UTI (20,000 U/kg), and another group was administrated high-dose UTI (50,000 U/kg). Twelve hours after contusion, neutrophil counting in bronchoalveolar lavage fluid (BALF) was performed and tumor necrosis factor α level and albumin level in BALF was tested. Lung tissue malondialdehyde levels, superoxide dismutase, and catalase activity was investigated, and blood gas analysis and contusion volume quantification using 3-dimensional computed tomography were performed. High-dose UTI significantly decreased neutrophil count and tumor necrosis factor α level in BALF (P<0.05) and decreased albumin level in BALF but without significance. Lung tissue malondialdehyde levels was significantly reduced, whereas superoxide dismutase and catalase activity were elevated by UTI with significance (P<0.05) especially high-dose UTI. No statistical significance was seen in the change in arterial oxygen partial pressure (PaO2) and contusion volume by UTI (P>0.05). UTI has a dose-dependent trend to ameliorate inflammatory and oxygen stress in pulmonary contusion-induced acute lung injury. However, the effect on hypoxemia and contusion lesion and the best administration regime should be investigated in future study.

Abstract
BACKGROUND The aim of this study was to examine whether administration of ulinastatin inhibits pro-inflammatory mediators and ameliorate visceral vasopermeability both in a rat model of major burn, and also in rat cultured endothelial cells stimulated with permeability-evoking mediators. METHODS Plasma levels of tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), myeloperoxidase (MPO), microvascular permeability, and water content of organ tissues were evaluated in a rodent model of a 55% TBSA full-thickness scald injury. Microvascular permeability was also evaluated with a cultured pulmonary microvascular endothelial cells (PMECs) monolayer after stimulation with trypsin, bradykinin, histamine, prostaglandin E2 and burn serum. RESULTS We found that the plasma levels of TNF-α, CRP, MPO, vascular permeability and water content of heart, lung, kidney, and small intestine tissues were significantly increased in animals after scald injury, and administration of ulinastatin lowered the levels TNF-α, CRP, MPO, vascular permeability and water content of those organ tissues. In vitro, ulinastatin lowered the levels of TNF-α, interleukin-6 (IL-6) and attenuated permeability in PMEC monolayers after being stimulated with burn serum or trypsin, but not by bradykinin, histamine or prostaglandin E2. CONCLUSIONS These results indicate that ulinastatin attenuates the systemic inflammatory response and visceral vasopermeability both in vivo and vitro, and may serve as a therapeutic agent for prevention of systemic inflammatory response and leakage of fluid into tissue after major burn.

Abstract
BACKGROUND Urinary trypsin inhibitors (UTI) have been widely used for the treatment of diseases including disseminated intravascular coagulation, shock, and pancreatitis. Since UTI synthesis is likely to be reduced in patients who have undergone liver resection, the incidence of inflammatory reactions may be increasing accordingly. For such patients, the liver enzyme increases after the operation can reflect liver damage. The purpose of this study was to examine if ulinastatin can inhibit liver enzyme increases after liver resection. METHODS After receiving Institutional Review Board approval, a retrospective chart review was performed on 201 patients who underwent hepatic resection from 2006 to 2010. We divided the records into the control (n = 69) and ulinastatin (n = 132) groups according to the use of intraoperative ulinastatin and compared the preoperative and postoperative laboratory test results. The number of patients who had > 400 U/L elevation of aspartate transaminase (AST) level after surgery was compared between the 2 groups. RESULTS The mean AST, alanine transaminase (ALT), and total bilirubin levels after liver resection were significantly lower in the ulinastatin group than in the control group. The number of patients who showed an AST > 400 U/L after liver resection was significantly higher in the control group (odds ratio = 3.02). CONCLUSIONS Ulinastatin attenuates the elevation of hepatic enzymes and bilirubin after liver resection.

Abstract
BACKGROUND Ischemia-reperfusion (I/R) injury may influence graft function after transplantation. Erythropoietin (EPO) attenuates I/R injury in various animal organs such as intestine, brain, and kidney. OBJECTIVE To evaluate the effects of pretreatment with recombinant human EPO (rhEPO) on I/R-induced heart injury. MATERIALS AND METHODS A rat model of I/R injury was established by ligating the left descending coronary artery for 30 minutes, followed by reperfusion for 4 hours. Fifty Sprague-Dawley rats were divided into 5 groups: sham operation; I/R; I/R+rhEPO, 100 U/kg; I/R+rhEPO, 1000 U/kg; and I/R+rhEPO, 5000 U/kg. Electrocardiograms were assessed continuously to note arrhythmia caused by reperfusion. Serum concentrations of interleukin (IL)-6 and IL-8, and tumor necrosis factor-alpha were measured at 2 and 4 hours after reperfusion. RESULTS The rhEPO-treated animals exhibited dosage-dependent significant reduction in the incidence of ventricular arrhythmia caused by reperfusion, and markedly decreased serum concentrations of IL-6, IL-8, and tumor necrosis factor-alpha (P < .05) compared with the I/R group (P < .05). CONCLUSION The rhEPO attenuates myocardial I/R injury in rats, at least in part related to inhibition of the system inflammatory response.
