Abstract
The management of severe burns remains a complex challenge. Adenosine, lidocaine, and magnesium (ALM) resuscitation therapy has been shown to protect against hemorrhagic shock and traumatic injury. The aim of the present study was to investigate the early protective effects of small-volume ALM fluid resuscitation in a rat model of 30% total body surface area (TBSA) thermal injury. Male Sprague-Dawley rats (320-340 g; n = 25) were randomly assigned to: 1) Sham (surgical instrumentation and saline infusion, without burn, n = 5), 2) Saline resuscitation group (n = 10), or 3) ALM resuscitation group (n = 10). Treatments were initiated 15-min after burn trauma, including 0.7 mL/kg 3% NaCl ± ALM bolus and 0.25-0.5 mL/kg/h 0.9% NaCl ± ALM drip, with animals monitored to 8.25-hr post-burn. Hemodynamics, cardiac function, blood chemistry, hematology, endothelial injury markers and histopathology were assessed. Survival was 100% for Shams and 90% for both ALM and Saline groups. Shams underwent significant physiological, immune and hematological changes over time as a result of surgical traums. ALM significantly reduced malondialdehyde levels in the lungs compared to Saline (P = .023), and showed minimal alveolar destruction and inflammatory cell infiltration (P < .001). ALM also improved cardiac function and oxygen delivery (21%, P = .418 vs Saline), reduced gut injury (P < .001 vs Saline), and increased plasma adiponectin (P < .001 vs baseline). Circulating levels of the acute phase protein alpha 1-acid glycoprotein (AGP) increased 1.6-times (P < .001), which may have impacted ALM's therapeutic efficacy. We conclude that small-volume ALM therapy significantly reduced lung oxidative stress and preserved alveolar integrity following severe burn trauma. Further studies are required to assess higher ALM doses with longer monitoring periods.

ANNALS OF BURNS AND FIRE DISASTERS 2023; 36:320-330. [PMID: 38680233 PMCID: PMC11041994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 07/22/2022] [Indexed: 05/01/2024]
Abstract
The combination of platelet-rich plasma (PRP) and stromal vascular fraction cells (SVFs) was beneficial in accelerating wound healing. This study aims to assess the effect of this combination in balancing the inflammatory process to accelerate burn healing. Thirty eligible Wistar rats were used in this study to establish a deep dermal degree burn wound model. They were randomly divided into four groups: locally injected with the combination of SVFs and PRP (n=9), vaseline (n=9), placebo (n=9), and healthy Wistar rats group (n=3), as treatment group, positive control group, negative control group and healthy control group, respectively. The burn wound tissue was excised from three separated sacrificed rats (8, 24 and 48 hours) to examine polymorphonuclear (PMN) and lymphocyte counts through the standard hematoxylin-eosin procedure and for cyclooxygenase2 (COX-2) expression through the immunohistochemical procedure. The highest PMN, lymphocyte cell count, and COX 2 expression were found at 8 hours in the local injection with the PRP combination SVF group (28,555±11,237, 8,111±3,218, and 4,666±2,309, respectively, p <0.05 except for COX 2). The regression analysis results showed that local injection of a combination of PRP and SVF could reduce PMN cells by 1.068 times, lymphocytes by 1.786 times, and COX 2 by 1.853 times greater than topical application with vaseline. The combined injection of PRP and SVF effectively heals deep burns by acutely increasing the PMN cell and lymphocyte count, and COX 2 expression. Conversely, the treatment decreased the PMN cell and lymphocyte count but not the COX 2 expression in the sub-acute phase of wound healing.

Significance of Pulmonary Endothelial Injury and the Role of Cyclooxygenase-2 and Prostanoid Signaling. BIOENGINEERING (BASEL, SWITZERLAND) 2023; 10:bioengineering10010117. [PMID: 36671689 PMCID: PMC9855370 DOI: 10.3390/bioengineering10010117] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 01/11/2023] [Accepted: 01/13/2023] [Indexed: 01/19/2023]
Abstract
The endothelium plays a key role in the dynamic balance of hemodynamic, humoral and inflammatory processes in the human body. Its central importance and the resulting therapeutic concepts are the subject of ongoing research efforts and form the basis for the treatment of numerous diseases. The pulmonary endothelium is an essential component for the gas exchange in humans. Pulmonary endothelial dysfunction has serious consequences for the oxygenation and the gas exchange in humans with the potential of consecutive multiple organ failure. Therefore, in this review, the dysfunction of the pulmonary endothel due to viral, bacterial, and fungal infections, ventilator-related injury, and aspiration is presented in a medical context. Selected aspects of the interaction of endothelial cells with primarily alveolar macrophages are reviewed in more detail. Elucidation of underlying causes and mechanisms of damage and repair may lead to new therapeutic approaches. Specific emphasis is placed on the processes leading to the induction of cyclooxygenase-2 and downstream prostanoid-based signaling pathways associated with this enzyme.

Abstract
Objectives To study the effect of parecoxib sodium (PS) application, combined with enhanced recovery after surgery (ERAS) nursing, on inflammation and knee joint function in elderly patients after total knee arthroplasty (TKA). Methods In this prospective cross-sectional study, we recruited 120 elderly patients treated with TKA who were randomly divided into two groups, the combine group and the control group, with 60 patients in each group. Patients in the control group received ERAS nursing and normal saline, and the patients in the combine group received ERAS nursing and PS. At different times after surgery, we compared the hemoglobin (Hb), complete white blood cell count (WBC), erythrocyte sedimentation rate (ESR), and serum IL-1β, TNF-α, and IL-6, and recovery time for different ranges of joint motion and the knee joint function HSS (hospital for special surgery scale) score between the two groups. Results On the third and seventh postoperative days, the levels of Hb in the patients of the combine group were significantly lower than those in the control group (p < 0.05), while the levels of WBC, ESR, serum IL-1β, TNF-α, and IL-6 in the patients of the combine group were all significantly lower than those in the control group (p < 0.05). Compared with the patients in the control group, the recovery time for 30, 60, 90, and 120 angles of joint motion in patients of the combine group was significantly decreased (p < 0.05), and the HSS score of patients in the combine group was significantly higher than that in the control group on the first, third, and sixth postoperative months (p < 0.05). Conclusion Elderly TKA patients who received PS application, combined with ERAS nursing, had lower inflammation in peripheral blood 2 weeks after operation and faster postoperative recovery of knee joint function.

Abstract
Parecoxib is a selective COX-2-specific inhibitor, which has been demonstrated to inhibit sepsis-induced systemic inflammation, but its role in sepsis-induced acute kidney injury has not been studied. This study was designed to investigate the effects of Parecoxib on sepsis-induced acute kidney injury. In this study, the mice sepsis model was established using an internationally recognized cecal ligation and puncture (CLP). Hematoxylin-eosin staining was performed to examine kidney injury. Biochemical kit was used to detect the expression of BUN and Cre in serum, and ELISA was used to detect the expression of inflammatory factors in renal tissue. Tunel staining was used to detect tissue apoptosis. Furthermore, CCK-8 assay was used to detect the cell viability of HK-2 cells and RT-qPCR was used to detect the expression of LPS-induced inflammatory factors in HK-2 cells.TUNEL staining was used to detect the level of cell apoptosis. Finally, the expressions of COX-2, p-NF-kB P65, p-IKKβ, NF-kB P65, IKKβ, Kim1, NGAL, iNOS, VEGF, VEGFR2, CD31 and apoptosis-related proteins in renal tissues and HK-2 cells were detected by Western blot. We discovered that parecoxib could alleviate renal pathological changes, reduce renal function injury, and inhibit renal pathology to inhibit the release of inflammatory factors in renal tissue. Parecoxib inhibited sepsis induced microvascular damage and apoptosis in renal tissue. Parecoxib reduced the inflammation and apoptosis of renal tubular epithelial cells induced by LPS. Our data suggest that Parecoxib ameliorates sepsis-induced kidney injury, and may have potential as a novel therapeutic method for treating sepsis-induced kidney injury.

Abstract
OBJECTIVE The association of non-steroidal anti-inflammatory drugs with postoperative acute kidney injury (AKI) is controversial. However, there are few studies focusing on the association between parecoxib and postoperative AKI. Our study aimed at the possible correlation between the intraoperative administration of cyclooxygenase-2 inhibitors parecoxib and perioperative AKI. DESIGN A retrospective cohort study. SETTING Third Xiangya Hospital of Central South University in Hunan Province, China. PARTICIPANTS The electronic medical records and laboratory results were obtained from 9246 adult patients (18-60 years) undergoing non-cardiac surgery performed between 1 January 2012 and 31 August 2017. Study groups were treated with or without parecoxib. INTERVENTIONS Univariable analysis identified demographic, preoperative laboratory and intraoperative factors associated with AKI. Logistic stepwise regression was used to calculate the adjusted OR of parecoxib and AKI association. RESULTS The incidence of AKI was lower in the parecoxib-administered group (4%) than that in the group without parecoxib (6.3%, p=0.005). In the multivariable regression analysis, postoperative AKI risk reduced by 39% (OR 0.61; 95% CI 0.43 to 0.87) in the parecoxib-administered group after adjusting for interference factors. Sensitivity analysis showed that postoperative AKI risk reduced in four subgroups: eGRF <90 mL/min·1.73/m2 (OR 0.49; 95% CI 0.29 to 0.82), non-smoker (OR 0.55; 95% CI 0.37 to 0.83), blood loss <1000 mL (OR 0.55; 95% CI 0.37 to 0.83) and non-hypotension (OR 0.57; 95% CI 0.38 to 0.84). CONCLUSIONS Thus, parecoxib is associated with a modest reduction of postoperative AKI risk among adult patients undergoing non-cardiac surgery.

Abstract
Background Platelet-rich plasma (PRP) is widely used to treat tendon injuries. Its therapeutic effect varies depending on the different cell components, and white blood cells (WBCs) may play an important role in this phenomenon. The purpose of this study was to evaluate how PRP with different concentrations of WBCs affect normal rabbit tendon and assess whether non-steroidal anti-inflammatory drugs (NSAIDs) can suppress the catabolic effects of WBCs. Methods Sixteen adult New Zealand White rabbits were used. Blood samples were collected from each rabbit, and PRP was extracted following two different protocols to obtain leukocyte-poor PRP (LP-PRP) and leukocyte-rich PRP (LR-PRP). LP-PRP or LR-PRP was injected into the patellar tendon of each rabbit, while normal saline (NS) was injected as control. In LR-PRP + NSAID group, Parecoxib was administered after LR-PRP injection. For each group, 2 rabbits were euthanatized at day 5 and 14. The patellar tendons were collected and stained with hematoxylin and eosin. A semi-quantitative approach was used to assess the inflammatory response and tendon destruction based on the evaluation of the WBCs, vascularization, fiber structure, and fibrosis. Results The LR-PRP group exhibited a higher total tendon score than the LP-PRP group at day 5 after PRP injection, but there was no significant difference between the two groups at day 14. For the NSAID group, the tendon score was lower than that of the LR-PRP group both at day 5 and 14. Conclusion LR-PRP can promote a higher inflammatory response than LP-PRP in the normal rabbit patellar tendon, and this effect can be suppressed by NSAIDs.

Abstract
Burns are caused by several mechanisms including flame, scald, chemical, electrical, and ionizing and non-ionizing radiation. Approximately half a million burn cases are registered annually, of which 40 thousand patients are hospitalized and receive definitive treatment. Burn care is very resource intensive as the treatment regimens and length of hospitalization are substantial. Burn wounds are classified based on depth as superficial (first degree), partial-thickness (second degree), or full-thickness (third degree), which determines the treatment necessary for successful healing. The goal of burn wound care is to fully restore the barrier function of the tissue as quickly as possible while minimizing infection, scarring, and contracture. The aim of this review is to highlight how tissue engineering and regenerative medicine strategies are being used to address the unique challenges of burn wound healing and define the current gaps in care for both partial- and full-thickness burn injuries. This review will present the current standard of care (SOC) and provide information on various treatment options that have been tested pre-clinically or are currently in clinical trials. Due to the complexity of burn wound healing compared to other skin injuries, burn specific treatment regimens must be developed. Recently, tissue engineering and regenerative medicine strategies have been developed to improve skin regeneration that can restore normal skin physiology and limit adverse outcomes, such as infection, delayed re-epithelialization, and scarring. Our emphasis will be centered on how current clinical and pre-clinical research of pharmacological agents, biomaterials, and cellular-based therapies can be applied throughout the continuum of burn care by targeting the stages of wound healing: hemostasis, inflammation, cell proliferation, and matrix remodeling.

Abstract
Objective To evaluate the effect of parecoxib on preventing postoperative shivering. Methods Main outcomes were the relative risk (odds ratio, OR) and 95% confidence interval (CI) relative to the incidence of shivering. Results Fourteen trials with 1,175 patients were analyzed. The pooled evidence suggested that parecoxib sodium, given before anesthesia or postoperatively (only 4 cases), had the potential to prevent postoperative shivering (OR = 0.21, 95% CI, 0.16, 0.29). Compared with the placebo, parecoxib sodium significantly lowered the incidence of postoperative shivering as follows: mild shivering [OR = 0.51, 95% CI (0.35, 0.74)]; moderate shivering [OR = 0.28, 95% CI (0.18, 0.45)]; severe shivering [OR = 0.18, 95% CI (0.10, 0.33)]. Compared with placebo, there was no significant association of parecoxib sodium with restlessness [OR = 0.95, 95% CI (0.59, 1.52)] or nausea/vomiting [OR = 0.24, 95% CI (0.09, 0.66)]. In addition, pethidine rescue was used significantly more often in the control group than in the parecoxib sodium group [OR = 0.22, 95% CI (0.09, 0.53)]. Conclusions Parecoxib sodium may be an effective strategy for preventing postoperative shivering.

Abstract
Background Cyclooxygenase-2 (COX-2) contributes to ventilation induced lung injury (VILI) and acute respiratory distress syndrome (ARDS). The objective of present study was to observe the therapeutic effect of parecoxib on VILI in ARDS. Methods In this parallel controlled study performed at Harbin Medical University, China between January 2016 and March 2016, 24 rats were randomly allocated into sham group (S), volume ventilation group/ARDS (VA), parecoxib/volume ventilation group/ARDS (PVA). Rats in the S group only received anesthesia; rats in the VA and PVA group received intravenous injection of endotoxin to induce ARDS, and then received ventilation. Rats in the VA and PVA groups were treated with intravenous injection of saline or parecoxib. The ratio of arterial oxygen pressure to fractional inspired oxygen (PaO2/FiO2), the wet to dry weight ratio of lung tissue, inflammatory factors in serum and bronchoalveolar lavage fluid (BALF), and histopathologic analyses of lung tissue were examined. In addition, survival was calculated at 24 h after VILI. Results Compared to the VA group, in the PVA group, PaO2/FiO2 was significantly increased; lung tissue wet to dry weight ratio; macrophage and neutrophil counts, total protein and neutrophil elastase levels in BALF; tumor necrosis factor-α, interleukin-1β, and prostaglandin E2 levels in BALF and serum; and myeloperoxidase (MPO) activity, malondialdehyde levels, and Bax and COX-2 protein levels in lung tissue were significantly decreased, while Bcl-2 protein levels were significantly increased. Lung histopathogical changes and apoptosis were reduced by parecpxib in the PVA group. Survival was increased in the PVA group. Conclusions Parecoxib improves gas exchange and epithelial permeability, decreases edema, reduces local and systemic inflammation, ameliorates lung injury and apoptosis, and increases survival in a rat model of VILI.

Significance: While the survival rate of the severely burned patient has improved significantly, relatively little progress has been made in treatment or prevention of burn-induced long-term sequelae, such as contraction and fibrosis. Recent Advances: Our knowledge of the molecular pathways involved in burn wounds has increased dramatically, and technological advances now allow large-scale genomic studies, providing a global view of wound healing processes. Critical Issues: Translating findings from a large number of in vitro and preclinical animal studies into clinical practice represents a gap in our understanding, and the failures of a number of clinical trials suggest that targeting single pathways or cytokines may not be the best approach. Significant opportunities for improvement exist. Future Directions: Study of the underlying molecular influences of burn wound healing progression will undoubtedly continue as an active research focus. Increasing our knowledge of these processes will identify additional therapeutic targets, supporting informed clinical studies that translate into clinical relevance and practice.

Abstract
The mechanism underlying pulmonary inflammation in thermal inhalation injury remains elusive. Cystic fibrosis, also hallmarked with pulmonary inflammation, is caused by mutations in CFTR, the expression of which is temperature-sensitive. We investigated whether CFTR is involved in heat-induced pulmonary inflammation. We applied heat-treatment in 16HBE14o- cells with CFTR knockdown or overexpression and heat-inhalation in rats in vivo. Heat-treatment caused significant reduction in CFTR and, reciprocally, increase in COX-2 at early stages both in vitro and in vivo. Activation of ERK/JNK, NF-κB and COX-2/PGE2 were detected in heat-treated cells, which were mimicked by knockdown, and reversed by overexpression of CFTR or VX-809, a reported CFTR mutation corrector. JNK/ERK inhibition reversed heat-/CFTR-knockdown-induced NF-κB activation, whereas NF-κB inhibitor showed no effect on JNK/ERK. IL-8 was augmented by heat-treatment or CFTR-knockdown, which was abolished by inhibition of NF-κB, JNK/ERK or COX-2. Moreover, in vitro or in vivo treatment with curcumin, a natural phenolic compound, significantly enhanced CFTR expression and reversed the heat-induced increases in COX-2/PGE2/IL-8, neutrophil infiltration and tissue damage in the airway. These results have revealed a CFTR-regulated MAPK/NF-κB pathway leading to COX-2/PGE2/IL-8 activation in thermal inhalation injury, and demonstrated therapeutic potential of curcumin for alleviating heat-induced pulmonary inflammation.
