Micellization Transformations of Sodium Oleate Induced by Gas Nucleation.

The interfacial properties of surfactant solutions are closely related to the micellization of surfactants. Temperature, salt type and concentration, pH, and other parameters affecting the micellization of surfactants have all been extensively investigated previously. However, the effect of dissolved gas on surfactant micellization and associated interfacial properties' transformations is not completely understood yet. In this study, sodium oleate (NaOl) was chosen as the research object, and the role of gas/gas nucleation in NaOl micellization was systematically investigated. The results indicated that the solution changed to be more turbid and the dissolved oxygen content increased after NaOl solutions were subjected to compression-decompression treatments. Meanwhile, the surface tension of the NaOl solution was altered, which was more pronounced when the concentration of NaOl was close to the critical micelle concentration. Given that the surface tension was a good indicator of the assembly and distribution state of the soluble monomers and insoluble micelles of NaOl, interactions between nucleated bubbles originating from the gas nucleation and NaOl molecules were unveiled through the analysis of the size distribution and zeta potential of sub-micro- and nanoscale particles in bulk solutions. Finally, possible micellization models of NaOl molecules, fully considering the role of gas/gas nucleation, were proposed under varying NaOl concentration conditions.

Triglyceride glucose index for predicting cardiovascular outcomes after percutaneous coronary intervention in patients with type 2 diabetes mellitus and acute coronary syndrome.

BACKGROUND: The triglyceride glucose (TyG) index, a simple surrogate estimate of insulin resistance, has been demonstrated to predict cardiovascular (CV) disease morbidity and mortality in the general population and many patient cohorts. However, to our knowledge, the prognostic usefulness of the TyG index after percutaneous coronary intervention (PCI) in patients with type 2 diabetes mellitus (T2DM) and acute coronary syndrome (ACS) has not been determined. This study aimed to evaluate the association of the TyG index with adverse CV outcomes in patients with T2DM and ACS who underwent PCI. METHODS: The TyG index was calculated using the formula ln[fasting triglycerides (mg/dL) × fasting glucose (mg/dL)/2]. The primary endpoint was the composite of all-cause mortality, non-fatal stroke, non-fatal myocardial infarction, or unplanned repeat revascularization. The association between the TyG index and adverse CV outcomes was assessed by Cox proportional hazards regression analysis. RESULTS: In total, 776 patients with T2DM and ACS who underwent PCI (mean age, 61 ± 10 years; men, 72.2%) were included in the final analysis. Over a median follow-up of 30 months, 188 patients (24.2%) had at least 1 primary endpoint event. The follow-up incidence of the primary endpoint rose with increasing TyG index tertiles. The multivariate Cox proportional hazards regression analysis adjusted for multiple confounders revealed a hazard ratio for the primary endpoint of 2.17 (95% CI 1.45-3.24; P for trend = 0.001) when the highest and lowest TyG index tertiles were compared. CONCLUSIONS: The TyG index was significantly and positively associated with adverse CV outcomes, suggesting that the TyG index may be a valuable predictor of adverse CV outcomes after PCI in patients with T2DM and ACS.

[Study on scavenging activity to DPPH free radical of different polarity components in Guizhou Miao medicine "bod zangd dak"].

The paper is aimed to search more natural plant antioxidants and further research and develop new medicinal plant resources in Guizhou. The Guizhou special miao medicine "bod zangd dak" was extracted with 60% ethanol. The antioxidant activity of the different polarity components separated from the extract was tested by DPPH method with ascorbic acid as positive control. The results showed that the IC50 of the different polarity components was as following: ascorbic acid (0.033 4 g x L(-1)) < ethyl acetate components (0.052 3 g x L(-1)) < total tannins components (0.054 9 g x L(-1)) < 60% ethanol extraction components (0.076 7 g x L(-1)) < butanol extraction components (0.110 g x L(-1)) < water-soluble polysaccharides components (0.168 g x L(-1)) < water extraction components (0.174 g x L(-1)) < water components after extraction (0.226 g x L(-1)) < total polysaccharides components (0.645 g x L(-1)). It is concluded that the different polarity components have different free radical scavenging activity and that provides a scientific basis for further search of the active ingredients and the activive mechanism.

[UPLC and HPLC analysis on contents of astilbin and engeletin in dong medicine "sunl gaems" of Guizhou origin by QAMS].

This study aimed to simultaneously determine the contents of astilbin and engeletin in dong medicine "sunl gaems" of Guizhou origin by quantitative analysis of multi-components by single marker (QAMS), with astilbin as the internal standard substance. On UPLC and HPLC chromatograms, different models of instruments were used to investigate relative correction factors (RCF), in order to discuss the interoperability of RCFs established in different chromatographic systems. The engeletin content was calculated based on the established RCFs and compared by the one point external standard method and the external standard working curve method, in order to verify the accuracy of QAMS. According to the result, in different chromatograms, the ratios between RCF and retention time of engeletin and astilbin had a good reproducibility, with RSD between 2.0% and 1.8%, both were less than 3%. The relative differences among results of QAMS, the external standard working curve method of dong medicine "sunl gaems" ranged between 1.6% and 3.9%, with RSD between 2.02%-0.80% in line with relevant requirements and Pearson correlation coefficient at 0.9998 (P <0.01). The findings showed that QAMS was an accurate, reliable and highly reproducible method to determine the contents of astilbin and engeletin in dong medicine "sunl gaems" of Guizhou origin and so could be used to control the inherent quality of the herb.

Transcranial Magnetic Stimulation Combined with Auricular Point Pressure Bean on Emotional Disorders in Elderly Patients after Intracerebral Hemorrhage Surgery: A Retrospective Cohort Study.

Objective: To investigate whether the combination of repetitive transcranial magnetic stimulation (rTMS) and auricular point pressure bean could effectively ameliorate postoperative affective disorder in elderly patients suffering from cerebral hemorrhage. Methods: From June 2020 to September 2023, 116 elderly patients with depression after cerebral hemorrhage, who underwent surgical procedures were divided into the exposure group and the control group. The division was determined based on whether received rTMS and traditional Chinese medicine auricular point pressure bean therapy. Hamilton anxiety scale (HAMA), Hamilton Depression scale (HAMD), National Institutes of Health Stroke scale (NIHSS), Montreal Cognitive Assessment scale (MoCA) and Mini Mental State examination scale (MMSE) were collected and compared between before intervention and after intervention. Results: In accordance with a 1 : 1 matching ratio, the patients in the study were paired using propensity score matching (PSM), with 53 patients in both the exposure group and the control group. There were no notable differences in baseline characteristics between the 2 groups (P > .05). Following the intervention, the HAMA score and the NIHSS score of the exposure group were markedly lower than those of the control group (P < .001). Additionally, theMoCA scores (P = .001) and MMSE scores (P < .001) in the exposure group were significantlyhigher. The difference score have a significant difference in HAMA score (P = .001), NIHSS score (P < .001), MoCA (P < .001) and MMSE scores (P < .001). Conclusion: The combination of rTMS therapy and auricular point pressure bean therapy in traditional Chinese medicine demonstrates can effectively relieve the anxiety level, postoperative emotional and cognitive disorders of elderly patients after intracerebral hemorrhage, and provide certain ideas and support for clinical treatment.

A Pharmacogenetic Panel-Based Prediction of the Clinical Outcomes in Elderly Patients with Coronary Artery Disease.

Clinical annotations for the actionable pharmacogenetic variants affecting the efficacy of cardiovascular drugs have been collected, yet their impacts on elderly patients with coronary artery disease (CAD) undergoing polypharmacy remain uncertain. We consecutively enrolled 892 elderly patients (mean age 80.7 ± 5.2) with CAD and polypharmacy. All the included patients underwent genotyping for 13 variants in 10 pharmacogenes (CYP2C19, CYP2C9, CYP4F2, CYP2D6, VKORC1, SLCO1B1, APOE, ACE, ADRB1, and MTHFR), which have the clinical annotations for 12 drugs that are commonly prescribed for patients with CAD. We found that 80.3% of the elderly CAD patients had at least one drug-gene pair associated with a therapeutical drug change. After adjusting for covariates, the number of drug-gene pairs was independently associated with a decreased risk of both major cardiovascular events (MACEs) (adjusted hazard ratio [HR]: 0.803, 95% confidence interval [CI]: 0.683-0.945, p = 0.008) and all-cause mortality (adjusted HR: 0.848, 95% CI: 0.722-0.996, p = 0.045), but also with an increased risk of adverse drug reactions (ADRs) (adjusted HR: 1.170, 95% CI: 1.030-1.329, p = 0.016). The Kaplan-Meier survival curves showed that compared to patients without a drug-gene pair, a significantly lower risk of MACEs could be observed in patients with a drug-gene pair during a 4-year follow-up (HR: 0.556, 95% CI: 0.325-0.951, p = 0.013). In conclusion, the carrier status of the actionable drug-gene pair is predictive for the clinical outcomes in elderly patients with CAD and polypharmacy. Implementing early or preemptive pharmacogenetic panel-guided polypharmacy holds the potential to enhance clinical outcomes for these patients.

Influences of plasma treatment parameters on the hydrophobicity of cathode and anode materials from spent lithium-ion batteries.

The recycling of spent lithium-ion batteries (LIBs) can not only reduce the potential harm caused by solid waste piles to the local environment but also provide raw materials for manufacturing new batteries. Flotation is an alternative approach to achieve the selective separation of cathode and anode active materials from spent LIBs. However, the presence of organic binder on the surface of hydrophilic lithium transition-metal oxides results in losses of cathode materials in the froth phase. In this study, plasma treatment was utilized to remove organic layers from cathode and anode active materials. Firstly, the correlations between plasma treatment parameters (e.g., input power, air flowrate, and treatment time) were explored and the contact angles of cathode and anode active materials were investigated by the response surface methodology. Secondly, differences in the flotation recoveries of cathode and anode active materials were enhanced with plasma modification prior to flotation, which is consistent with the contact angle measurement. Finally, the plasma-modification mechanisms of hydrophobicity of cathode and anode active materials were discussed according to Fourier Transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analyses. The proposed method could be a promising tool to enhance the flotation separation efficiency of cathode and anode active materials for the recycling of spent LIBs.

Investigation of the migration of natural organic matter-iron-antimony nano-colloids in acid mine drainage.

Colloids can potentially affect the efficacy of traditional acid mine drainage (AMD) treatment methods such as precipitation and filtration. However, it is unclear how colloids affect antimony (Sb) migration in AMD, especially when natural organic matter (NOM) is present. To conduct an in-depth investigation on the formation and migration behavior of NOM, iron (Fe), Sb and NOM-Fe-Sb colloids in AMD, experiments were performed under simulated AMD conditions. The results demonstrate significant variations in the formation of NOM-Fe-Sb colloids (1-3-450 nm) as the molar ratio of carbon to iron (C/Fe) increases within acidic conditions (pH = 3). Increasing the C/Fe molar ratio from 0.1 to 1.2 resulted in a decrease in colloid formation but an increase in particulate fraction. The distribution of colloidal Sb, Sb(III), and Fe(III) within the NOM-Fe-Sb colloids decreased from 68 % to 55 %, 72 % to 57 %, and 68 % to 55 %, respectively. Their distribution in the particulate fraction increased from 28 % to 42 %, 21 % to 34 %, and 8 % to 27 %. XRD, FTIR, and SEM-EDS analyses demonstrated that NOM facilitates the formation and crystallization of Fe3O4 and FeSbO4 crystalline phases. The formation of the colloids depended on pH. Our results indicate that NOM-Fe-Sb colloids can form when the pH ≤ 4, and the proportion of colloidal Sb fraction within the NOM-Fe-Sb colloids increased from 9 % to a maximum of 73 %. Column experiments show that the concentration of NOM-Fe-Sb colloids reaches its peak and remains stable at approximately 3.5 pore volumes (PVs), facilitating the migration of Sb in the porous media. At pH ≥ 5, stable NOM-Fe-Sb colloids do not form, and the proportion of colloidal Sb fraction decreases from 7 % to 0 %. This implies that as pH increases, the electrostatic repulsion between colloidal particles weakens, resulting in a reduction in the colloidal fraction and an increase in the particulate fraction. At higher pH values (pH ≥ 5), the repulsive forces between colloidal particles nearly disappear, promoting particle aggregation. The findings of this study provide important scientific evidence for understanding the migration behavior of NOM-Fe-Sb colloids in AMD. As the pH gradually shifts from acidic to near-neutral pH during the remediation process of AMD, these results could be applied to develop new strategies for this purpose.

Platinum-Tellurium Heterojunction Nanosheet Assemblies for Efficient Direct Formic Acid Electrooxidation Catalysis.

Two-dimensional (2D) heterojunction nanomaterials offer exceptional physicochemical and catalytic properties, thanks to their special spatial electronic structure. However, synthesizing morphologically uniform 2D platinum (Pt)-based metallic nanomaterials with diverse crystalline phases remains a formidable challenge. In this study, we have achieved the successful synthesis of advanced 2D platinum-tellurium heterojunction nanosheet assemblies (Ptx-PtTe2 HJNSAs, x = 0, 1, 2), seamlessly integrating both trigonal PtTe2 (t-PtTe2) and cubic Pt (c-Pt) phases. By enabling efficient electron transport and leveraging the specific electron density present at the heterojunction, the Pt2-PtTe2 HJNSAs/C demonstrated exceptional formic acid oxidation reaction (FAOR) activity and stability. Specifically, the specific and mass activities reached 8.4 mA cm-2 and 6.1 A mgPt-1, which are 46.7 and 50.8 times higher than those of commercial Pt/C, respectively. Impressively, aberration-corrected high-angle annular dark field scanning transmission electron microscopy (AC-HAADF-STEM) revealed a closely packed arrangement of atomic layers and a coherent intergrowth heterogeneous structure. Density functional theory (DFT) calculations further indicated that rearrangement of electronic structure occurred on the surface of Pt2-PtTe2 HJNSAs resulting in a more favorable dehydrogenation pathway and excellent CO tolerance, beneficial for performance improvement. This work inspires the targeted exploration of Pt-based nanomaterials through 2D heterostructure design, leading to an important impact on fuel cell catalysis and beyond.

[Content detemination of total tannin in Smilax glabra with reddish brown and off-white colored cross section].

There are two types of decoction of Smilax glabra due to its reddish brown or off-white colored cross section. These two kinds of decoction were found that they have large difference in anti-inflammatory effects and chemical constituents in the preliminary experiments. Comparing and analyzing the content of total tannin in these two kinds of decoction of S. glabra from 28 areas by UV-Vis spectrophotometry were first used to provide some experimental and theoretical development and utilization of this medicinal resource and quality control. Also, the sample recovery test required in Chinese Pharmacopoeia was improved by adding tannic acid instead of gallic acid to samples.

A comparative study on the influence of single and combined ultrasounds assisted flake graphite flotation.

Ultrasound has emerged as a promising technique for improving the mineral flotation performance. However, limited research exists regarding the influence of different ultrasound types on the flotation process. Specifically, the impact of combined ultrasound and the comparison of horn- and bath-type ultrasounds on flotation have not been fully investigated. To address this knowledge gap, a comprehensive study to explore the effects of different ultrasonic pretreatments on the flotation of flake graphite was conducted. A Box-Behnken design is employed to analyze the effects of combined ultrasound on graphite flotation. By characterizing the properties of graphite samples before and after the ultrasonic treatment, the aim is to elucidate the mechanism underlying the impact of ultrasound on graphite flotation. The experimental results indicated that the ultrasonic cavitation intensity exerted a significant influence on the graphite flotation recovery. Both horn- and bath- type ultrasounds contributed to flotation, but horn-type ultrasound demonstrated a more pronounced effect, leading to a 7% increase in flotation recovery, whereas bath-type ultrasound resulted in only a 2% increase. Furthermore, the cavitation intensity of combined ultrasound was found to be higher than that of single-frequency ultrasound in the same duration. However, the performance of graphite flotation was better with short duration combined ultrasound pretreatment, while the opposite trend was observed for a long duration ultrasound pretreatment. These findings may inform the development of more efficient and effective ultrasonic pretreatments for flotation separation processes.

ß1-blockers in the reduction of bleeding risk in patients prescribed with potent dual antiplatelet therapy after acute coronary syndrome or percutaneous coronary intervention.

BACKGROUND: ß1-blockers could improve clinical outcomes in patients with coronary artery disease by lowering the heart rate, blood pressure, and myocardial contractility. Moreover, recent studies have suggested that ß1-blockers may also have the potential to reduce bleeding risk. OBJECTIVES: This study aimed to evaluate the association between ß1-blockers and bleeding risk in the patients prescribed with potent dual antiplatelet therapy (DAPT) after acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI). METHODS: Patients with ACS or undergoing PCI treated by DAPT of ticagrelor and aspirin were consecutively recruited. Follow-up for all eligible patients was conducted for 1 year. Major bleeding outcomes were defined as events that were type ≥2 based on the Bleeding Academic Research Consortium (BARC) criteria. RESULTS: A total of 1,113 eligible ticagrelor-treated patients were recruited. During the 1-year follow-up interval, 142 (12.6%) patients experienced BARC ≥2 bleedings including 23 patients (2.1%) suffering BARC ≥3 bleedings, with the most common site of bleeding located in the gastrointestinal tract. ß1-blockers treatment was associated with a lower risk of BARC ≥2 bleedings (11.2% vs. 23.3%, adjusted HR: 0.42, 95% CI: 0.28-0.62, P < 0.01). Moreover, metoprolol (11.1% vs. 23.3%, adjusted HR: 0.56, 95% CI: 0.37-0.83, P < 0.01) and bisoprolol (11.3% vs. 23.3%, adjusted HR: 0.56, 95% CI: 0.33-0.96, P = 0.04) had similar effects on the reduction of bleeding risk. CONCLUSION: ß1-blockers might be beneficial for the reduction of bleeding risk in potent dual antiplatelet therapy patients with ACS or undergoing PCI.

[Comparison of anti-inflammatory effect and analysis of astilbin red and white transverse section Smilax glabra in 28 collection sites].

OBJECTIVE: Astilbin in 28 Smilax glabra (red and white cross-section) from different sources was determined by HPLC. Pharmacodynamics and component of S. glabra was investigated through inflammation experiment (penetration type). METHOD: The analysis was performed on a Hypersil ODS2 column (4.6 mm x 250 mm, 5 microm) with the mobile phase of acetonitrile and 0. 1% acetic acid aqueous (21: 79) at a flow rate of 1.0 mL x min(-1). The detection wavelength was 291 nm, and the column temperature was 25 degrees C. Anti-inflammatory effect was compared from two type cross-section of Smilax glabra in capillary permeability experiment. RESULT: Linear correlation was good in the range of 0.003 379-4.004 microg, and the average recoveries were 100.1%, 101.9%, 99.3%, respectively. The content of astilbin in white and red transverse section were 0.19%-2.46% and 2.10%-5.92%, respectively. Anti-inflammatory efficiency of sectioned red and white were were 21% and 32%, respectively. CONCLUSION: Astilbin content and anti-inflammatory effect is significantly different between red and white transverse section of S. glabra, the content of astilbin is not positively related with anti-inflammatory effect.

Manganese oxide-modified biochar derived from discarded mushroom-stick for the removal of Sb(III) from aqueous solution.

In this study, discarded mushroom-stick, which is widely available, was selected as a precursor to prepare MnO2-modified biochar (MBC) for Sb(III) removal. Several characterisation methods (SEM, BET, XPS, FT-IR, and XRD) were used to explore the mechanisms of antimony adsorption onto MBC. The results showed that MBC is a mesoporous material with a fluffy structure and a higher specific surface area (23.56 and 32.09 m2·g-1) than PBC600 (13.62 m2·g-1), exhibiting superior and stable adsorption capacities for Sb(III) (50.30 mg·g-1 for 1/30MBC600 and 64·12 mg·g-1 for 1/20MBC600) across a wide pH range (pH 4-8). X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FT-IR) spectroscopy analyses indicated that the main oxides and functional groups involved in the adsorption were manganese oxides and hydroxyl groups. Forty-four per cent of the adsorbed Sb(III) was oxidised to Sb(V) by manganese oxides or hydroxyl groups both on the surface of biochar and in solution. According to adsorption kinetics and isotherms, the adsorption process of Sb(III) is chemisorption, which includes monolayer and multilayer heterogeneous chemisorption processes. To sum up, MBC is an excellent adsorbent for the capture of Sb(III) from contaminated water with strong potential for future application.

Assessment of the CHA2DS2-VASc Score for the Prediction of Death in Elderly Patients With Coronary Artery Disease and Atrial Fibrillation.

Purpose: Coronary artery disease (CAD) and atrial fibrillation (AF) often coexist and lead to a much higher risk of mortality in the elderly population. The aim of this study was to investigate whether the CHA2DS2-VASc score could predict the risk of death in elderly patients with CAD and AF. Methods: Hospitalized patients aged ≥65 years with a diagnosis of CAD and AF were recruited consecutively. Patients were divided into 5 groups according to the CHA2DS2-VASc score (≤2, =3, =4, =5, and ≥6). At least a 1-year follow-up was carried out for the assessment of all-cause death. Results: A total of 1,579 eligible patients were recruited, with 582 all-cause deaths (6.86 per 100 patient-years) occurring during a follow-up of at least 1 year. With the increase in the CHA2DS2-VASc score, the 1-year and 5-year survival rate decreased (96.4% vs. 95.7% vs. 94.0% vs. 86.5% vs. 85.7%, respectively, P < 0.001; 78.4% vs. 68.9% vs. 64.6% vs. 55.5% vs. 50.0%, respectively, P < 0.001). Compared with the patients with CHA2DS2-VASc score <5, for patients with CHA2DS2-VASc score ≥5, the adjusted hazard ratio for death was 1.78 (95% CI: 1.45-2.18, P < 0.001). The predictive values of the CHA2DS2-VASc score ≥5 for in-hospital (C-index = 0.66, 95% CI: 0.62-0.69, P < 0.001), 1-year (C-index = 0.65, 95% CI: 0.63-0.67, P < 0.001) and 5-year (C-index = 0.60, 95% CI: 0.59-0.61, P < 0.001) death were in comparable. Conclusion: In elderly patients with concomitant CAD and AF, the CHA2DS2-VASc score can be used to predict death with moderate accuracy.

Prognostic value of CHADS2 and CHA2DS2-VASc scores for post-discharge outcomes in patients with acute coronary syndrome undergoing percutaneous coronary intervention.

The CHADS2 and CHA2DS2-VASc scores were initially developed to assess the risk of stroke or systemic embolism in patients with atrial fibrillation (AF). Recently, these two scoring systems have been demonstrated to predict long- and short-term cardiovascular (CV) outcomes in many patient cohorts. However, to the best of our knowledge, their prognostic value has not been fully elucidated in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). This study aimed to investigate the association of CHADS2 and CHA2DS2-VASc scores with CV outcomes in such patients.We included a total of 915 ACS patients undergoing PCI in this study. CHADS2 and CHA2DS2-VASc scores were calculated from data collected before discharge. The primary endpoint was defined as a composite of major adverse CV events (MACE) including overall death, nonfatal stroke, nonfatal myocardial infarction (MI) and unplanned repeat revascularization. We assessed MACE's relationship to CHADS2 and CHA2DS2-VASc scores using Cox proportional-hazard regression analyses.Mean follow-up duration was 918 days. MACE occurred in 167 (18.3%) patients. A higher CHADS2 score was associated with reduced event-free survival (EFS) from MACE (logrank test, P = .007) with differences potentiated if stratified by CHA2DS2-VASc score (logrank test, P < .001). Univariate analysis showed that both CHADS2 and CHA2DS2-VASc scores were good predictors of MACE. In the multivariate Cox proportional-hazard regression analysis, CHA2DS2-VASc score (hazard ratio [HR], 1.15; 95% confidence interval [CI] 1.04-1.27; P = .007) remained a useful predictor of MACE; however, CHADS2 score was no longer associated with increased risk of MACE. C-statistics for CHA2DS2-VASc score, GRACE (Global Registry of Acute Coronary Events) hospital discharge risk score (GRACE Score) and SYNTAX (Synergy between PCI with TAXUS and Cardiac Surgery) Score II (SS II) in predicting MACE were 0.614, 0.598, and 0.609, respectively.CHA2DS2-VASc score was an independent and significant predictor of MACE in ACS patients undergoing PCI, and its discriminatory performance was not inferior to those of GRACE Score and SS II.

In Vivo Effects of Salbutamol Residues on Blood Lipid, Lung Structure, Gene Expression, and Gut Microorganism Composition.

Salbutamol (SAL), one of the prohibited veterinary drugs, has been proven to be harmful to animals, but very few studies reported the underlying mechanism of actions and the effects after SAL intake. In this study, Ba-Ma minipigs were used as the animal model to demonstrate the impacts of SAL residues on blood lipid and the lung bronchial structures and the regulation of gene expression and gut microorganism population. The results showed that (1) SAL decreased the indexes of serum lipid and organ, (2) SAL widely retained in various tissues and organs, (3) the lung bronchial expanded under the influence of SAL, (4) the gene expression of growth-related ghrelin has increased, and (5) the residues of SAL affected the composition of gut microorganism population, which could be associated with the mechanism of action of SAL on pig. The findings suggest that SAL could be harmful to minipigs by altering the blood lipid, bronchial morphology, gastric mucosal gene expression, and the gut microorganism population.

Predictive performance of aortic arch calcification for clinical outcomes in patients with acute coronary syndrome that undergo percutaneous coronary intervention: A prospective clinical study.

Currently, little is known regarding the predictive utility of aortic arch calcification (AAC) for clinical outcomes in patients with acute coronary syndrome (ACS) who undergo percutaneous coronary intervention (PCI). The present study was designed to investigate the predictive performance of AAC as detected by chest x-ray for clinical outcomes among ACS patients undergoing PCI.A total of 912 patients who were diagnosed as ACS and treated with PCI were included in this prospective, cohort study. All study participants received chest x-rays on admission, and a semiquantitative 4-point scale was used to assess the extent of AAC. The primary end point was defined as a composite of major adverse cardiovascular events (MACE) comprising death, nonfatal stroke, nonfatal myocardial infarction, and unplanned repeat revascularization. The key secondary end point was the composite of cardiovascular death, nonfatal stroke, and nonfatal myocardial infarction. The prognostic values of AAC were assessed in multivariate Cox-proportional hazards regression analyses adjusted for major confounders.The mean follow-up duration was 917 days and, during the follow-up period, MACE occurred in 168 (18.4%) patients. Kaplan-Meier analyses revealed significantly higher incidences of the primary and key secondary end points in patients with higher AAC grades (log-rank test; all P < .001). Multivariate Cox-proportional hazards regression analyses showed that, in comparison to AAC grade 0, the hazard ratios of AAC grades 1, 2, and 3 for predicting MACE were 1.63 (95% confidence interval [CI] 0.99-2.67), 2.15 (95% CI 1.27-3.62), and 2.88 (95% CI 1.41-5.86), respectively. The C-index of the variables, including peripheral arterial disease and serum levels of triglyceride for predicting MACE, was 0.644 (95% CI 0.600-0.687) versus 0.677 (95% CI 0.635-0.719) when AAC grades were also included; the continuous net reclassification improvement was 16.5% (8.7%-23.4%; P < .001).The extent of AAC as detected by chest x-ray is an independent predictor of MACE among ACS patients undergoing PCI. Further research is warranted to evaluate whether specific treatment strategies that are established based on AAC extent are needed for optimal risk reduction in relevant patient populations.

Dietary Apostichopus japonicus Alleviates Diabetes Symptoms and Modulates Genes Expression in Kidney Tissues of db/db Mice.

The effects of Apostichopus japonicus enzymatic hydrolysate on the regulation of dyslipidemia, pathoglycemia, and transcription changes in kidney tissues of db/db mice were evaluated. In this study, the symptoms of diabetes in db/db mice were alleviated after 10 weeks of treatments with low (db/db + LD group) and high dose (db/db + HD group) of Apostichopus japonicus enzymatic hydrolysate, and the high dose treatment showed a better antidiabetic effect. Compared with the db/db group, the fasting blood glucose levels (36.84 ± 7.82 vs 25.18 ± 6.84 mmol/L, P < 0.01), the urine glucose levels (45.44 ± 3.93 vs 22.66 ± 5.58 mmol/L, P < 0.01), and the serum insulin sensitivity index (-4.65 ± 0.43 vs -4.74 ± 0.75, P > 0.05) in the db/db + HD group were decreased, whereas the fasting plasma insulin (3.12 ± 1.08 vs 5.54 ± 1.82 µg/L, P < 0.01) and the serum insulin resistance index (5.01 ± 2.02 vs 5.96 ± 2.49, P < 0.05) were increased. Subsequently, the kidney transcription profiles were measured in the db/db group and db/db + HD group via microarray, and the results show that Apostichopus japonicus hydrolysate induced differential expression of 77 genes. Among these genes, the down-regulation of genes ntrK1 and ptpN5 played vital roles, as this effect induced the further down-regulation of neurotrophin tyrosine kinase, protein tyrosine phosphatase, and other transcription factors, which are involved in the classical mitogen-activated protein kinases (MAPK) and p38MAPK signaling pathways. The inhibited MAPK and p38MAPK signaling pathways are involved in glycometabolism and the control of lipid metabolism, and they regulate the occurrence and development of diabetic nephropathy.
