ABSTRACT: Acute liver injury (ALI) is an important medical problem that requires effective therapy. Astaxanthin (AST) is a carotenoid, and the beneficial effects of astaxanthin, including anti-oxidative, anti-inflammatory and anti-tumour activities, have been identified. The present study was designed to elucidate the protective effects of astaxanthin against ALI and their underlying mechanisms. RAW264.7 macrophages were treated with dimethyl sulfoxide combined with different doses of astaxanthin for 12 h. Mice were fed with or without astaxanthin for up to 7 days. LPS was administered to induce inflammation. We assessed histopathology, oxidative stress, inflammation and apoptosis .The results indicated that astaxanthin attenuated LPS-induced oxidative stress, inflammation and cell apoptosis both in vivo and in vitro. In vivo and in vitro experiments showed that astaxanthin down regulated the nuclear factor-kappa beta (NF-κB), nuclear factor erythroid 2-related factor 2 (Nrf2) and NLR family pyrin domain containing 3 (NLRP3) signalling pathways, inhibiting the LPS-induced inflammatory response, oxidative stress and cell apoptosis, and alleviating LPS-induced ALI in mice.

RESUMO: A lesão hepática aguda (ALI) é um problema médico importante que requer terapia eficaz. A astaxantina (AST) é um carotenóide, e os efeitos benéficos da astaxantina, incluindo atividades antioxidantes, anti-inflamatórias e antitumorais, foram identificados. O presente estudo foi desenhado para elucidar os efeitos protetores da astaxantina contra ALI e seus mecanismos subjacentes. Macrófagos RAW264.7 foram tratados com dimetil sulfóxido combinado com diferentes doses de astaxantina por 12 h. Os camundongos foram alimentados com ou sem astaxantina por até sete dias. O LPS foi administrado para induzir a inflamação. Histopatologia, estresse oxidativo, inflamação e apoptose foram avaliados. Os resultados indicaram que a astaxantina atenuou o estresse oxidativo induzido por LPS, inflamação e apoptose celular in vivo e in vitro. Experimentos in vivo e in vitro mostraram que a astaxantina regulou negativamente as vias de sinalização do fator nuclear-kappa beta (NF-κB), fator nuclear 2 relacionado ao eritróide 2 (Nrf2) e domínio de pirina da família NLR contendo 3 (NLRP3), inibindo o LPS- resposta inflamatória induzida, estresse oxidativo e apoptose celular e alívio da ALI induzida por LPS em camundongos.

Abstract Background Glomus Tumor (GT) are benign neoplasms that originate from mesenchymal cells. It presents as tenderness and cold allodynia in the digits, especially in the subungual region. There are a few studies that investigated the mechanism of pain. Objectives To analyze the clinical-pathologic characteristics of GT and to identify the expression of IL-1β, IL-6, and CGRP in it, further, to explore the possible mechanism of pain. Methods The clinical and pathological data of 60 GT patients were retrospectively analyzed. Tissue microarrays and immunohistochemistry were used to measure the expression of IL-1β, IL-6 and CGRP. Results GT is more common in females and the ratio of male to was near to 1:2, mostly in middle-aged people. It often occurs in fingertips, especially the thumbs. Patients often present with spontaneous pain, tenderness, and cold hypersensitivity. Both the two pain mediators IL-1β and IL-6 were highly expressed in GT cells of patients with and without cold hypersensitivity. While CGRP was not expressed in GT. Study limitations Low sample size and further research is needed to explore the specific mechanism. Conclusions IL-1β and IL-6 were highly expressed in GT cells, suggesting that IL-1β and IL-6 have certain nociceptive roles in GT. In the 4 patients with cold intolerance, the intensity of IL-1β and IL-6 staining was also strong, suggesting that they may not play a role in the cold hypersensitivity. However, since there are only 4 patients with cold intolerance, it’s necessary to conduct further in-depth research using a larger sample size. The specific role of CGRP in GT has not been found yet.

Abstract Background In contemporary society, with the accelerated pace of work and life, more and more people feel different degrees of stress. Long-term stress may not only lead to insomnia, but also to mental health problems (e.g., anxiety and depression), which has a significant impact on people's quality of life and mental health. Objective This study primarily investigates the mechanism through which stress affects sleep quality among college students. Methods We conducted research on 1653 Chinese college students using four scales with high reliability and validity: stress, the Pittsburgh Sleep Quality Index, social anxiety, and rumination. Results The study found: (1) Stress can significantly and positively predict sleep quality and rumination; (2) Rumination can positively predict social anxiety; (3) Social anxiety can positively predict sleep quality; (4) Stress can affect sleep quality through social anxiety and rumination separately, and stress can also affect sleep quality through the chained mediation of rumination and social anxiety. Conclusion This study reveals the relationship and mechanisms between stress and sleep quality. It not only deepens the research on the impact of stress on sleep quality but also provides theoretical support and new methods for mental health professionals to help clients improve their sleep quality. In practice, in addition to using some common psychological intervention methods to help individuals reduce stress, we should pay more attention to how to help clients reduce rumination and social anxiety, This is significant in improving the quality of an individual's sleep. society Longterm Long term insomnia e.g., eg e g (e.g. depression, depression , depression) peoples s 165 validity Index found 1 (1 2 (2 3 (3 4 (4 separately practice individual e.g. (e.g 16 ( e.g

In this study, Al-Si-Cu-Mg composites reinforced with Silicon carbide (SiC) particles and/or Carbon nanotubes (CNTs) were fabricated using semi-solid stirring casting technology (SSC). The aim of the study was to investigate the influence of SiC and/or CNTs on the mechanical properties, microstructural evolution, and deformation mechanisms of the Al-Si-Cu-Mg alloy. The findings indicated that the presence of SiC/CNTs in the composite had a significant effect on refining the α-Al phase and altering its grain orientation. Additionally, the results obtained from EBSD and TEM revealed that the microstructure of the Al-Si-Cu-Mg-SiC/CNTs hybrid composite (HAMC) underwent dynamic recrystallization (DRX) and static recrystallization (SRX), resulting in a fine equiaxed recrystallized structure. This process also led to the formation of high-angle grain boundaries (HAGBs) through dislocation rearrangement. The SiC particles were evenly distributed within the matrix, ensuring good interface bonding between SiC and α-Al phases. Moreover, the CNTs reacted with the matrix, resulting in the in-situ formation of the Al4C3 phase at the interface. The addition of SiC/CNTs significantly increased the tensile strength of HAMC at 25°C and 250°C, from 319MPa and 178MPa to 438MPa and 331MPa. Examination of the fracture surface of the hybrid composite unveiled that void formation occurred primarily at the regions surrounding the matrix-particle interface.

Abstract Background: The anthracycline chemotherapeutic antibiotic doxorubicin (DOX) can induce cumulative cardiotoxicity and lead to cardiac dysfunction. Long non-coding RNAs (lncRNAs) can function as important regulators in DOX-induced myocardial injury. Objective: This study aims to investigate the functional role and molecular mechanism of lncRNA OXCT1 antisense RNA 1 (OXCT1-AS1) in DOX-induced myocardial cell injury in vitro. Methods: Human cardiomyocytes (AC16) were stimulated with DOX to induce a myocardial cell injury model. OXCT1-AS1, miR-874-3p, and BDH1 expression in AC16 cells were determined by RT-qPCR. AC16 cell viability was measured by XTT assay. Flow cytometry was employed to assess the apoptosis of AC16 cells. Western blotting was used to evaluate protein levels of apoptosis-related markers. Dual-luciferase reporter assay was conducted to verify the binding ability between miR-874-3p and OXCT1-AS1 and between miR-874-3p and BDH1. The value of p<0.05 indicated statistical significance. Results: OXCT1-AS1 expression was decreased in DOX-treated AC16 cells. Overexpression of OXCT1-AS1 reversed the reduction of cell viability and promotion of cell apoptosis caused by DOX. OXCT1-AS1 is competitively bound to miR-874-3p to upregulate BDH1. BDH1 overexpression restored AC16 cell viability and suppressed cell apoptosis under DOX stimulation. Knocking down BDH1 reversed OXCT1-AS1-mediated attenuation of AC16 cell apoptosis under DOX treatment. Conclusion: LncRNA OXCT1-AS1 protects human myocardial cells AC16 from DOX-induced apoptosis via the miR-874-3p/BDH1 axis.

Abstract Fast calculations are widely required in the traditional applications and the emerging digital twin fields. For those considerations, a novel physics-based fast algorithm, namely generalized rotation-superposition method, is proposed for fast calculating linear elastic responses of generalized rotationally axisymmetric structures under arbitrary mechanical loads. This improved method breaks through the limitations of the previous basic rotation-superposition method in rotational similarity of load and structural axisymmetry, and greatly expands its application scope. In this paper, firstly, the basic theory of the rotation-superposition algorithm is introduced; secondly, the theoretical model of the generalized rotation-superposition method is established; thirdly, the effectiveness and accuracy are verified by using finite element simulations; finally, through a complex case study, the applicability of the generalized rotation-superposition method for complex engineering problems and its advantages in efficiently obtaining massive amounts of data are further illustrated. fields considerations physicsbased physics based rotationsuperposition rotation superposition loads axisymmetry scope paper firstly introduced secondly established thirdly simulations finally study illustrated

The overexpression of P-glycoprotein (P-gp/ABCB1) is a leading cause of multidrug resistance (MDR). Hence, it is crucial to discover effective pharmaceuticals that counteract ABCB1-mediated multidrug resistance. FRAX486 is a p21-activated kinase (PAK) inhibitor. The objective of this study was to investigate whether FRAX486 can reverse ABCB1-mediated multidrug resistance, while also exploring its mechanism of action. The CCK8 assay demonstrated that FRAX486 significantly reversed ABCB1-mediated multidrug resistance. Furthermore, western blotting and immunofluorescence experiments revealed that FRAX486 had no impact on expression level and intracellular localization of ABCB1. Notably, FRAX486 was found to enhance intracellular drug accumulation and reduce efflux, resulting in the reversal of multidrug resistance. Docking analysis also indicated a strong affinity between FRAX486 and ABCB1. This study highlights the ability of FRAX486 to reverse ABCB1-mediated multidrug resistance and provides valuable insights for its clinical application.

Abstract Objective: Aortic Dissection (AD) is one of the most fatal acute diseases in cardiovascular diseases, with rapid onset and progression and a high fatality rate. This study aims to investigate the clinical values of non-enhancement peripheral pulse-gating rapid magnetic resonance imaging in deterministic diagnosis of AD. Methods: Aorta magnetic resonance imaging was performed in 21 healthy volunteers at a 1.5t MR scanner sequences including cardiac-gated and peripheral pulse-gated True-FISP and HASTE were carried out separately. Acquisition Time (TA), Signal to Noise Ratio (SNR), Contrast Noise Ratio (CNR), and entirety of vessel wall blood flow artifacts were measured and compared. A total of 56 AD cases were displayed by non-enhancement peripheral pulse-gating fast MR imaging, and the results were compared with pathological findings or CTA of the aorta. The dissection rupture, tear film, true and false lumen, thrombosis, hydropericardium, and the main branches of AD were evaluated respectively. Results: There were no significant differences in SNR, CNR, entirety of the vessel wall, and blood flow artifact between cardiac-gated and peripheral pulse-gated fast MR imaging. Non-enhancement pulse-gated fast scanning takes less TA time. By the pulse-gated non-enhancement fast MR imaging, the dissection rupture, tear film, true and false cavity, thrombosis, hydropericardium, and the main branches of aortic dissection were shown clearly. Multi-planar and multi-angle scans helped to show the extent of entrapment rupture, whereas partial complex tears or bi-directional tears were slightly less well visualized. Conclusion: Non-enhancement peripheral pulse-gated rapid magnetic resonance imaging can be used for deterministic diagnosis of AD.

Jun N-terminal kinase pathway-associated phosphatase (JKAP) regulates CD4+ T-cell differentiation and immunity, which are linked to mental disorders. This study aimed to explore the relationships between JKAP and T helper 17 (Th17)/regulatory T (Treg) ratio, as well as their associations with anxiety and depression in postpartum women. Serum JKAP were measured by enzyme-linked immunosorbent assay and blood Th17 and Treg cells were measured by flow cytometry in 250 postpartum women. Anxiety and depression were evaluated by the 6-item State-Trait Anxiety Inventory (STAI6) and Edinburgh Postnatal Depression Scale (EPDS). Anxiety and depression rates were 22.0 and 28.4%, respectively, among postpartum women. Notably, JKAP was negatively associated with the STAI6 (P=0.002) and EPDS scores (P<0.001) in postpartum women and was lower in postpartum women with anxiety (P=0.023) or depression (P=0.002) than in those without. Moreover, JKAP was inversely related to Th17 cells and Th17/Treg ratio but positively correlated with Treg cells in postpartum women (all P<0.001). Interestingly, Th17 cells and Th17/Treg ratio were both positively associated with STAI6 and EPDS scores in postpartum women (all P<0.001). Furthermore, Th17 cells and Th17/Treg ratio were lower in postpartum women with anxiety or depression than in those without (all P<0.01). Nevertheless, Treg cells were not linked to anxiety or depression in postpartum women. JKAP was negatively associated with Th17 cells and Th17/Treg ratio; moreover, they all related to anxiety and depression in postpartum women, indicating that JKAP may be involved in postpartum anxiety and depression via interactions with Th17 cells.

Emerging evidence demonstrates that curcumin has an inhibitory effect on non-small cell lung cancer (NSCLC), and its targets and mechanism of action need further exploration. The goal of this study was to explore the potential targets and mechanism of curcumin against NSCLC by network pharmacology, bioinformatics, and experimental validation, thereby providing more insight into combination treatment with curcumin for NSCLC in preclinical and clinical research. Curcumin targets against NSCLC were predicted based on HIT2.0, STD, CTD, and DisGeNET, and the core targets were analyzed via protein-protein interaction network construction (PPI), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and molecular docking. The gene expression levels of samples in A549 cells, NCI-H460, and curcumin treated groups were detected by real-time quantitative PCR. A total of 67 common targets between curcumin and NSCLC were collected by screening public databases. GO and KEGG analysis suggested that curcumin treatment of NSCLC mainly involves cancer-related pathways, such as PI3K-AKT signaling pathway, Foxo signaling pathway, microRNAs, MAPK signaling pathway, HIF-1 signaling pathway, etc. The targets with the highest degree were identified through the PPI network, namely CASP3, CTNNB1, JUN, IL6, MAPK3, HIF1A, STAT3, AKT1, TP53, CCND1, VEGFA, and EGFR. The results of the in vitro experiments showed that curcumin treatment of NSCLC down-regulated the gene expressions of CCND1, CASP3, HIF1A, IL-6, MAPK3, STAT3, AKT1, and TP53. Our findings revealed that curcumin functions as a potential therapeutic candidate for NSCLC by suppressing multiple signaling pathways and interacting with multiple gene targets. nonsmall non small NSCLC, , (NSCLC) exploration pharmacology bioinformatics validation research HIT20 HIT HIT2 0 HIT2.0 STD CTD DisGeNET proteinprotein protein PPI, (PPI) GO, (GO) KEGG, (KEGG) docking A54 cells NCIH460, NCIH460 NCIH NCI H460, H460 H NCI-H460 realtime real time PCR 6 databases cancerrelated related PI3KAKT PIKAKT PI3K AKT PI K pathway microRNAs HIF1 HIF 1 HIF- etc CASP3 CASP CTNNB1 CTNNB JUN IL6 IL MAPK3 HIF1A HIFA STAT3 STAT AKT1 TP53 TP CCND1 CCND VEGFA EGFR downregulated down regulated 6, IL-6 (NSCLC HIT2.

ABSTRACT Through a long-term micro-area positioning experiment (2006-2017), the precise fertilization locations of spring maize (Zea mays L.) in Jilin, China, were investigated using an embedded cement bucket pot. The effects of different fertilization placements and additional application of organic manure on maize yield, biomass, grain nutrient uptake, and soil fertility were examined. Six treatments were designed: base fertilizer + topdressing shallow application (BF1TD1); base fertilizer deep + topdressing shallow application (BF2TD1); base fertilizer + topdressing deep application (BF1TD2); base fertilizer deep + topdressing deep application (BF2TD2); base fertilizer + topdressing + organic manure shallow application (BF1TD1 + OS); and base fertilizer + topdressing shallow application + organic manure deep application (BF1TD1 + OD). After 12 years of continuous experimentation, the findings revealed that BF2TD2, BF1TD1 + OS, and BF1TD1 + OD exhibited 10.59 %, 25.17 %, and 29.34 % higher average yields than BF1TD1, respectively. Deep topdressing was more beneficial in increasing maize yield and nutrient accumulation, and additionally, increasing the use of organic fertilizer enhanced plant biomass and nutrient uptake. Over the 12 years considered, the soil organic matter in the 0-20 cm and 20-40 cm layers increased by 45.96 % and 80.61 %, respectively, and the soil pH increased from 0.38 to 0.48. In general, the deep application of organic manure was more beneficial for soil retention as it can increase soil fertility in the 0-40 cm layer. Considering the high yield and nutrient absorption and utilization of maize, technical advancement for soil fertilizer in whole-field tillage layers was crucial. longterm long term microarea micro area 20062017, 20062017 2006 2017 , (2006-2017) Zea L.

Resumo Fundamento A hipertrofia cardíaca patológica (HC) sustentada é um fator de risco independente para aumento da incidência e mortalidade de eventos cardiovasculares. Objetivos Esta pesquisa foi projetada para desvendar o papel do RNA não codificante longo (LncRNA) CCAT2 na progressão da HC. Métodos Procedimentos de constrição aórtica transversal (TAC) foram conduzidos para construir um modelo de HC in vivo induzido por sobrecarga de pressão. O tratamento com angiotensina II (Ang II) foi utilizado para induzir células hipertróficas de cardiomiócitos de rato H9c2. Resultados Os resultados in vivo mostraram que o silenciamento de CCAT2 reduziu a área de superfície dos cardiomiócitos, aliviou a fibrose cardíaca e diminuiu os níveis de β-MHC, ANP e BNP em modelos de camundongos HC. Os resultados in vitro revelaram que o knockdown de CCAT2 reduziu a área de superfície celular e atenuou os níveis de β-MHC, ANP e BNP em células hipertróficas H9c2. Além disso, o silenciamento de CCAT2 diminuiu os níveis de β-catenina ativa, GSK-3β fosforilada e genes alvo Wnt (c-Myc, ciclinaD1 e c-Jun) em camundongos HC e células H9c2 hipertróficas. É importante ressaltar que o tratamento com o ativador da via Wnt / β-catenina LiCl reverteu a supressão do knockdown de CCAT2 na área de superfície celular H9c2 e nos níveis de MHC, ANP e BNP. Conclusões Coletivamente, o silenciamento do CCAT2 desempenha um papel protetor contra a HC através da inativação da sinalização Wnt/β-catenina, o que sugere que o CCAT2 pode se tornar um alvo terapêutico promissor para o HC.

Abstract Background Sustained pathological cardiac hypertrophy (CH) is an independent risk factor for increased incidence and mortality of cardiovascular events. Objectives This research was designed to unravel the role of long non-coding RNA (LncRNA) CCAT2 in CH progression. Methods Transverse aortic constriction (TAC) procedures were conducted to construct a pressure overload-induced in vivo CH model. Angiotensin II (Ang II) treatment was utilized to induce hypertrophic rat cardiomyocyte H9c2 cells. Results In vivo results showed that silencing of CCAT2 reduced cardiomyocyte surface area, alleviated cardiac fibrosis, and decreased β-MHC, ANP, and BNP levels in CH mouse models. In vitro results revealed that CCAT2 knockdown reduced cell surface area and attenuated β-MHC, ANP, and BNP levels in hypertrophic H9c2 cells. Besides, CCAT2 silencing decreased the levels of active β-catenin, phosphorylated-GSK-3β, and Wnt target genes (c-Myc, cyclinD1, and c-Jun) in CH mice and hypertrophic H9c2 cells. Importantly, treatment with the Wnt/β-catenin pathway activator LiCl reversed the suppression of CCAT2 knockdown on H9c2 cell surface area and MHC, ANP, and BNP levels. Conclusions Collectively, CCAT2 silencing plays a protective role against CH through inactivating the Wnt/β-catenin signaling, which suggests that CCAT2 might become a promising therapeutic target for CH.

Abstract Introduction: Propofol is a widely used anesthetic and its dose is closely related to aging. Telomere length (TL) is a unique heritable trait, and emerging as a biomarker of aging, health and disease. Telomerase RNA component (TERC) plays an important role in maintaining TL. We proposed a hypothesis that propofol dose in general anesthesia can be predicted by measuring TL before operation, which greatly reduced the risk of anesthesia, especially the elderly. Methods: The association between the propofol dose in anesthesia induction and: TL in the DNA of peripheral blood leukocytes; body weight; sex; difference of the Bispectral Index (BIS) before and after anesthesia induction in patients was evaluated by multivariable linear regression analyses. The mutation at the 5’end or 3’end of TERC was detected. We recruited 100 patients of elective surgery. Results: We found that propofol dose in anesthesia induction was clearly correlated significantly with TL (r = 0.78, p < 0.001), body weight (r = 0.84, p = 0.004), sex (r = 0.83, p= 0.84, p = 0.004), sex (r = 0.83, p = 0.004), and difference of BIS before and after anesthesia induction (r = 0.85, p = 0.029). By comparing the absolute values of standardized regression coefficients (0.58, 0.21, 0.19, and 0.12) of the four variables, it can be seen that TL contributes the most to the propofol dose in anesthesia induction. However, the mutation at the 5’ end or 3’ end of TERC was not found. Conclusions: These findings provide preliminary evidence that the propofol dose in anesthesia induction was clearly correlated with genetically determined TL. TL may be a promising predictor of the propofol dose, which is beneficial to improve the safety of anesthesia and reduce perioperative complications.

Abstract Objective: To investigate the optimal timing of initial intravenous immunoglobulin (IVIG) treatment in Kawasaki disease (KD) patients. Methods: KD patients were classified as the early group (day 1-4), conventional group (day 5-7), conventional group (day 8-10), and late group (after day 10). Differences among the groups were analyzed by ANOVA and Chi-square analysis. Predictors of IVIG resistance and the optimal cut-off value were determined by multiple logistic regression analyses and receiver operating characteristic (ROC) curve analysis. Results: There were no significant differences in IVIG resistance among the 4 groups (p = 0.335). The sensitivity analysis also confirmed no difference in the IVIG resistance between those who started the initial IVIG ≤ day 7 of illness and those who received IVIG >day 7 of illness (p = 0.761). In addition, patients who received IVIG administration more than 7 days from the onset had a higher proportion of coronary artery abnormalities (p = 0.034) and longer length of hospitalization (p = 0.033) than those who started IVIG administration less than 7 days. The optimal cut-off value of initial IVIG administration time for predicting IVIG resistance was >7 days, with a sensitivity of 75.25% and specificity of 82.41%. Conclusions: IVIG therapy within 7 days of illness is found to be more effective for reducing the risk of coronary artery abnormalities than those who received IVIG >day 7 of illness. IVIG treatment within the 7 days of illness seems to be the optimal therapeutic window of IVIG. However, further prospective studies with long-term follow-up are required.

Abstract Background Neuropathic pain typically refers to the pain caused by somatosensory system injury or diseases, which is usually characterized by ambulatory pain, allodynia, and hyperalgesia. Nitric oxide produced by neuronal nitric oxide synthase (nNOS) in the spinal dorsal cord might serve a predominant role in regulating the algesia of neuropathic pain. The high efficacy and safety, as well as the plausible ability in providing comfort, entitle dexmedetomidine (DEX) to an effective anesthetic adjuvant. The aim of this study was to investigate the effect of DEX on the expression of nNOS in spinal dorsal cord in a rat model with chronic neuropathic pain. Methods Male Sprague Dawley (SD) rats were randomly assigned into three groups: sham operation group (sham), (of the sciatic nerve) operation (CCI) group, and dexmedetomidine (DEX) group. Chronic neuropathic pain models in the CCI and DEX groups were established by sciatic nerve ligation. The thermal withdrawal latency (TWL) was measured on day 1 before operation and on day 1, 3, 7 and 14 after operation. Six animals were sacrificed after TWL measurement on day 7, and 14 days after operation, in each group, the L4–6 segment of the spinal cords was extracted for determination of nNOS expression by immunohistochemistry. Results Compared with the sham group, the TWL threshold was significantly decreased and the expression of nNOS was up-regulated after operation in the CCI and DEX groups. Compared with the CCI grou[, the TWL threshold was significantly increased and the expression of nNOS was significantly down-regulated on day 7 and 14 days after operation in the DEX group. Conclusion Down-regulated nNOS in the spinal dorsal cord is involved in the attenuation of neuropathic pain by DEX. diseases allodynia hyperalgesia (nNOS safety comfort (DEX adjuvant SD (SD sham, , (sham) (CCI ligation (TWL 3 L46 L L4 6 L4– immunohistochemistry upregulated up regulated grou, grou grou[ downregulated down Downregulated Down (sham

Resumo Antecedentes A dor neuropática refere-se tipicamente à dor causada por lesões ou doenças do sistema somatossensorial. De modo geral, é caracterizada por dor à ambulação, alodinia e hiperalgesia. O óxido nítrico produzido pela enzima óxido nítrico sintase neuronal (nNOS) na medula espinhal dorsal pode ter um papel predominante na regulação da dor neuropática. A alta eficácia e segurança, bem como a plausível capacidade de proporcionar conforto, faz com que a dexmedetomidina (DEX) seja um adjuvante anestésico eficaz. O objetivo deste estudo foi investigar o efeito da DEX na expressão de nNOS na medula espinhal dorsal em um modelo de ratos com dor neuropática crônica. Métodos Ratos Sprague Dawley (SD) machos foram distribuídos aleatoriamente em três grupos: grupo de cirurgia simulada (sham), grupo de cirurgia (do nervo ciático; CCI) e grupo dexmedetomidina (DEX). Os modelos de dor neuropática crônica nos grupos CCI e DEX foram estabelecidos por ligadura do nervo ciático. A latência de retirada térmica (TWL) foi medida no dia 1 antes da cirurgia e nos dias 1, 3, 7 e 14 após o procedimento. Seis animais de cada grupo foram eutanasiados após a medida de TWL nos dias 7 e 14 após a cirurgia e o segmento L4-6 da medula espinhal foi extraído para determinação da expressão de nNOS por imuno-histoquímica. Resultados Em comparação ao grupo sham, o limiar de TWL diminuiu significativamente e a expressão de nNOS foi regulada de maneira positiva após a cirurgia nos grupos CCI e DEX. Comparado ao grupo CCI, o limiar de TWL aumentou de forma significativa e a expressão de nNOS caiu significativamente diminuída nos dia 7 e 14 após a cirurgia no grupo DEX. Conclusão A regulação negativa de nNOS na medula espinhal dorsal está envolvida na atenuação da dor neuropática pela DEX. referese refere se somatossensorial geral ambulação hiperalgesia (nNOS segurança conforto (DEX eficaz SD (SD sham , (sham) ciático .
