RESUMO Antecedentes O tabagismo tem sido considerado fator de risco para doenças cardiovasculares, câncer, depressão e outras doenças em relatos anteriores, e o tabagismo ativo é considerado fator de risco para acidente vascular cerebral hemorrágico. Além disso, um estudo retrospectivo mostrou que os fumantes do sexo masculino apresentavam risco aumentado de sangramento por malformação arteriovenosa (MAV), em comparação com os não fumantes. No entanto, o efeito do tabagismo passivo na ruptura da MAV cerebral em mulheres não fumantes não foi abordado. Objetivo: Este estudo teve como objetivo avaliar o impacto da exposição ao tabaco no risco de sangramento de MAV em mulheres não fumantes. Métodos Foram incluídas 393 mulheres não fumantes diagnosticadas com MAV. Elas foram divididas em um grupo com sangramento (205 mulheres) e um grupo sem sangramento (188 mulheres). Realizamos análise univariada e multivariada nesses dois grupos. Na análise univariada, foram analisados os fatores de risco que podem estar relacionados ao sangramento de MAV. Na análise multivariada, a relação entre tabagismo passivo e ruptura de MAV foi analisada por meio da correção de fatores de confusão. Resultados A análise multivariada mostrou que a proporção de tabagismo passivo foi estatisticamente diferente entre o grupo com sangramento e o grupo sem sangramento (OR = 1,609; IC = 1,031-2,509; p = 0,036). Conclusão O tabagismo passivo pode aumentar o risco de sangramento de MAV em mulheres não fumantes. Esse risco aumentado pode estar relacionado à resposta inflamatória, danos na parede vascular, distúrbios hemodinâmicos, alterações na aterosclerose e alterações na expressão gênica causadas pelo tabagismo passivo.

ABSTRACT Background Smoking has been considered to be a risk factor for cardiovascular disease, cancer, depression and other diseases in previous reports, and active smoking is considered to be a risk factor for hemorrhagic stroke. In addition, a retrospective study showed that male smokers were at increased risk of bleeding from arteriovenous malformation (AVM), compared with non-smokers. However, the effect of passive smoking on rupturing of cerebral AVM in non-smoking women has not been addressed. Objective This study aimed to assess the impact of tobacco exposure on AVM bleeding risk in non-smoking women. Methods A total of 393 non-smoking women diagnosed with AVM were included. They were divided into a bleeding group (205 women) and a non-bleeding group (188 women). We conducted univariate and multivariate analysis on these two groups. In univariate analysis, risk factors that might be related to AVM bleeding were analyzed. In multivariate analysis, the relationship between passive smoking and AVM rupture was analyzed by correcting confounding factors. Results Multivariate analysis showed that the proportion of passive smoking was statistically different between the bleeding group and the non-bleeding group (OR = 1.609; CI = 1.031-2.509; p = 0.036). Conclusion Passive smoking may increase the risk of AVM bleeding in non-smoking women. This increased risk may be related to the inflammatory response, vascular wall damage, hemodynamic disorders, changes in atherosclerosis and changes in gene expression caused by passive smoking.

Abstract Vitamin D (VD) was reported to play protective roles in skeletal muscle. This study aimed to explore whether endoplasmic reticulum (ER) stress inhibition is associated with the protective effects of VD/VD receptor (VDR) signaling on skeletal muscle functions. C2C12 skeletal muscle cells were treated with palmitic acid (PA) and then incubated with different concentrations of 1,25-(OH)2-vitamin D3 (VD3), and we found that VD3 improved the impaired cell viability induced by PA and increased VDR expression in a dose-dependent manner. Then 100 nM VD3 treatment and VDR overexpression both ameliorated PA-induced ER stress, apoptosis, inflammation and glucose uptake inhibition in C2C12 myocytes. Furthermore, VDR knockdown reversed the protective effects of VD3 on C2C12 cell functions. Additionally, PA-treated C2C12 cells were treated with VD3 alone or together with AMPK signaling inhibitor Compound C. VD3 promoted phosphorylation of AMPK and SIRT1 expression, while Compound C reversed these effects and abolished the protective effects of VD3 in C2C12 cells. High-fat diet (HFD)-fed mice were treated with VD3, and VD3 alleviated skeletal muscle loss and insulin resistance in mice. In conclusion, VD inhibited AMPK/SIRT1-mediated ER stress by increasing VDR expression, and further ameliorated skeletal muscle loss and insulin resistance in mice.

Abstract Cytoplasmic male sterility (CMS) is a maternally inherited trait that derives from the inability to produce functional pollen in higher plants. CMS results from recombination of the mitochondrial genome. However, understanding of the molecular mechanism of CMS in pepper is limited. In this study, comparative transcriptomic analyses were performed using a near-isogenic CMS line 14A (CMS-14A) and a maintainer line 14B (ML-14B) as experimental materials. A total of 17,349 differentially expressed genes were detected between CMS-14A and ML-14B at the PMC meiosis stage. Among them, six unigenes associated with CMS and 108 unigenes involved in energy metabolism were identified. The gene orf165 was found in CMS-14A. When orf165 was introduced into ML-14B, almost 30% of transgenic plants were CMS. In addition, orf165 expression in transgenic CMS plants resulted in abnormal function of some genes involved in energy metabolism. When orf165 in transgenic CMS plant was silenced, the resulted orf165-silenced plant was male fertile and the expression patterns of some genes associated with energy metabolism were similar to ML-14B. Thus, we confirmed that orf165 influenced CMS in pepper.

Summary Objective: The aim of this study was to evaluate the effect of rhubarb on extravascular lung water (EVLW) in patients with acute respiratory distress syndrome (ARDS). Method: A total of 80 patients with ARDS were randomly divided into a treatment group (40 cases) and control group (40 cases). Patients in the treatment group received rhubarb (30.0 g/d) and patients in the control group received conventional therapy for seven consecutive days. Extravascular lung water index (EVLWI) and pulmonary vascular permeability index (PVPI) were determined using pulse contour cardiac output (PiCCO) technology, and the oxygenation index was measured by blood gas analysis at baseline and on days 3, 5 and 7 after treatment. Results: The oxygenation index was higher and the levels of EVLWI and PVPI were lower after treatment in the two groups; however, these indexes showed significant differences on the 5th and 7th days after rhubarb treatment compared with the results in the control group (p<0.05). Conclusion: Rhubarb can decrease EVLWI and PVPI, and improve oxygenation in patients with ARDS.

Abstract: Poly(aspartic acid-citric acid) copolymer (PAC) is a new product of poly(carboxylic acid) scale inhibitor. The study aims to develop a "green" water treatment agent for calcium phosphate scale. The article compares the efficiency of three polymeric antiscalants, poly(aspartic acid-citric acid) copolymer (PAC), polymaleic acid (HPMA) and a compound inhibitor (PAC-HPMA), for calcium phosphate scale prevention under varying experimental conditions. Inhibitor concentration, calcium concentration, system pH, temperature and experimental time were varied to determine their influences on inhibitor performance by the static scale inhibition method. The copolymer (PAC) was characterized by FTIR, 1H NMR and 13C NMR. The compound inhibitor was applied in the actual circulating cooling water system. An atomic force microscope (AFM), X-ray powder diffraction (XRD) and a scale formation process analysis were used to explore the scale inhibition mechanism. The results showed that scale inhibition rates of PAC, HPMA and PAC-HPMA against Ca3(PO4)2 were, respectively, about 23%, 41.5% and 63% when the dosage was 8 mg/L in the experiment. The compound inhibitor showed the better inhibition performance than the above two kinds of monomers. Under the actual working conditions, the inhibition rate of compound inhibitor was close to 100% and completely met the actual application requirements of scale inhibitor in circulating cooling water systems. The main inhibition mechanism was the decomposition-chelation dispersion effect. The compound inhibitor can be used as an efficient "green" scale inhibitor for calcium phosphate.
