The aim of the present study was to investigate the role of plasmacytoma variant translocation gene 1 (PVT1) in the occurrence and development of sepsis-induced inflammation and cardiac dysfunction and its underlying mechanism. A sepsis rat model was first established by cecal ligation and puncture. The mRNA levels of PVT1 and microRNA-143 in the myocardial tissues of rats were detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis. Cardiac function, levels of myocardial injury markers and inflammatory indicators were detected following PVT1 knockdown. The regulatory effect of microRNA-143 on PVT1 was assessed using a luciferase reporter gene assay and RT-qPCR analysis. The specific role of PVT1 in regulating the mitogen-activated protein kinase (MAPK)/nuclear factor (NF)-κB pathway was detected using western blot analysis. PVT1 was downregulated and microRNA-143 was upregulated in the myocardial tissues of sepsis rats. The left ventricular peak pressure was markedly decreased in the sepsis rats. By contrast, the left ventricular end diastolic pressure, levels of inflammatory indicators, myocardial injury markers and complement proteins of C5 and C5a were increased in the sepsis rats. The above changes were reversed by PVT1 knockdown or the upregulation of microRNA-143. MicroRNA-143 was confirmed as being bound to PVT1 using the luciferase reporter gene assay and RT-qPCR analysis. Upregulated PVT1 was capable of activating the MAPK/NF-κB pathway. Taken together, PVT1 was upregulated in the myocardial tissues of sepsis rats, which inhibited cardiac function and promoted the secretion of inflammatory factors; and the mechanism was associated with the MAPK/NF-κB pathway.

Source of materialToanethanol solution (5 ml) of 2 ¢ -hydroxyacetophenone (274.50 mg, 2.01 mmol) wasadded ane thanol solution (3 ml) of 1,4-bis-(aminooxy)butane (124.30 mg, 1.03 mmol). After the solution hadbeen stirred at55°Cfor 2h,the mixture wasfiltered. The residue wasw ashed successively with ethanol and ethanol/hexane (1:4),r espectively. The isolated compound wasd ried under reduced pressure and purified by recrystallization from ethanol to yield 119.10 mg of colorless crystallinesolid (yield 34 %, m.p. 132-133°C). The single crystals were obtained atRT by slow evaporationf rom amixture of tetrahydrofuran/methanol( 1:1, v / v ) and 2,2¢ -[(1,4-butylene)dioxybis(nitriloethylidyne)]-diphenol. DiscussionParticularattention hasr ecently been paid to the synthesis and study of salen and its derivatives. This is due to avarietyofreasons, not the least of which is theircrucialrole in inorganic and organometallic chemistry, e.g., they caneasily form metallosalen complexes with metalions asversatile chelating ligands. Some of them or their metalcomplexes are used in various organic reaction processes asc atalysts [1], models of reaction centers of metalloenzymes [2], have fascinating magnetic properties [3] and are nonlinearopticalmaterials [4]. They canalso be used asbiologicalm odels in understanding the structure of biomolecules and biologicalprocesses [5,6]. Most of their important features of these compounds are their preparative accessibility, diversityand structuralv ariability, which make them more attractive. Although the important properties of salen and its derivatives have been well-documented, it still seems there could be new and specific applications for such aunique group of compounds. The salen ligandsinmost of their metalcomplexes are stable insolution or solid state, however, the C = Nbonds often suffer exchange reaction asw ell ash ydrolysis. Because the oxime-type ligandsare more stable to resist the metathesis of C = Nbonds

The title chelating bis‐oxime compound, C17H18N2O4, has been synthesized by the reaction of 1,3‐bis(aminooxy)propane with salicylaldehyde in ethanol. An O—H...N intramolecular hydrogen bond is observed between a hydroxyl group and an oxime N atom.

Acute kidney injury (AKI) is a complex syndrome with a variety of possible etiologies and symptoms. It is characterized by high mortality and poor recovery of renal function. The incidence and mortality rates of patients with AKI in intensive care units are extremely high. It is generally accepted that early identification and prompt treatment of AKI are essential to improve outcomes. This study aimed to develop a model based on risk stratification to identify and diagnose early stage AKI for improved prognosis in critically ill patients.This was a single-center, retrospective, observational study. Based on relevant literature, we selected 13 risk factors (age, sex, hypertension, diabetes, coronary heart disease, chronic kidney disease, total bilirubin, emergency surgery, mechanical ventilation, sepsis, heart failure, cancer, and hypoalbuminemia) for AKI assessment using the Kidney Disease Improving Global Outcomes (KDIGO) diagnostic criteria. Univariate and multivariate analyses were used to determine risk factors for eventual entry into the predictive model. The AKI predictive model was established using binary logistic regression, and the area under the receiver operating characteristic curve (AUROC or AUC) was used to evaluate the predictive ability of the model and to determine critical values.The AKI predictive model was established using binary logistic regression. The AUROC of the predictive model was 0.81, with a sensitivity of 69.8%, specificity of 83.4%, and positive likelihood ratio of 4.2.A predictive model for AKI in critically ill patients was established using 5 related risk factors: heart failure, chronic kidney disease, emergency surgery, sepsis, and total bilirubin; however, the predictive ability requires validation.

Background: To explore the potential role of the platelet/lymphocyte ratio (PLR) as a prognostic marker in septic patients with acute kidney injury (AKI) and to provide theoretical evidence for the epidemiological study of the prognosis of patients with septic AKI in its early stage. Methods: A pilot study was conducted. A logistic regression analysis was conducted to screen the risk factors, and the selected factors were performed using multiple logistic regression analysis; a Receiver Operating Characteristic curve was used to determine the optimal cutoff value of the PLR and then to calculate the sensitivity and specificity of the PLR ratio. Results: Mechanical ventilation, platelet count, PLR, and arterial blood lactate concentration have a correlation with sepsis ( p < 0.05). An elevated PLR is significantly associated with a worse prognosis of sepsis-induced AKI (higher mortality). Conclusion: The PLR might be an effective factor in predicting a worse prognosis of septic AKI patients.
