摘要： Excessive alcohol consumption(≥15 drinks per week)causes chronic diseases and multiple other health conditions.Nevertheless,alcohol beverages have been used as a vital medicine ingredient in various cultures since ancient times.A wealth of epidemiological and experimental research has shown that light-moderate alcohol consumption,regardless of beverage type,is associated with reducing cardiovascular incidence and mortality rate.Due to the disparities in raw materials,fermentation techniques,production environment,etc.,alcoholic beverages tend to possess different non-ethanol component profiles,thus resulting in varying degrees of health effects.Furthermore,bioactive compounds in alcohol are continuously discovered as well as the mechanisms underlying their cardioprotective contributions at a molecular level.This article elucidates the epidemiology of moderate alcohol consumption and various cardiovascular conditions,along with the limitations and controversies of current studies.In addition,protective effects and putative mechanisms of both ethanol and non-ethanol components of wine,beer,and Chinese Baijiu,the three most representative alcoholic beverages worldwide,are to be evaluated within the context of a rational drinking pattern.

摘要： Iran experienced one of the largest methanol poisoning outbreaks shortly after the coronavirus pandemic due to misinformation about the beneficial effects of alcohol in preventing and treating this viral infection.^([1])According to the Iran Legal Medicine Organization(LMO),over 3,100 methanol toxicity cases and 728 deaths were reported across the country,resulting in a syndemic of methanol poisoning.^([2])There is very little literature on the electrographic predictors of cardiovascular mortality in methanol poisoned patients.^([3])

摘要： Background & Objective: Chronic excessive alcohol consumption causes white matter degeneration with myelin loss and impaired neuronal conductivity. Subsequent rarefaction of myelin accounts for the sustained deficits in cognition, learning, and memory. Correspondingly, chronic heavy or repeated binge alcohol exposures in humans and experimental models alter myelin lipid composition leading to build-up of ceramides which can be neurotoxic and broadly inhibitory to brain functions. Methods: This study examined the effects of chronic + binge alcohol exposures (8 weeks) and intervention with myriocin, a ceramide inhibitor, on neurobehavioral functions (Open Field, Novel Object Recognition, and Morris Water Maze tests) and frontal lobe white matter myelin lipid biochemical pathology in an adult Long-Evans rat model. Results: The ethanol-exposed group had significant deficits in executive functions with increased indices of anxiety and impairments in spatial learning acquisition. Myriocin partially remediated these effects of ethanol while not impacting behavior in the control group. Ethanol-fed rats had significantly smaller brains with broadly reduced expression of sulfatides and reduced expression of two of the three sphingomyelins detected in frontal white matter. Myriocin partially resolved these effects corresponding with improvements in neurobehavioral function. Conclusion: Therapeutic strategies that support cerebral white matter myelin expression of sulfatide and sphingomyelin may help remediate cognitive-behavioral dysfunction following chronic heavy alcohol consumption in humans.

摘要： BACKGROUND Primary liver cancer(PLC)is a major contributor to cancer-related deaths.Data on global and country-specific levels and trends of PLC are essential for understanding the effects of this disease and helping policymakers to allocate resources.AIM To investigate the association between the burden of PLC and socioeconomic development status.METHODS Cancer mortality and incidence rates were obtained from the Global Burden of Disease(GBD)2019,and the data were stratified by country and territory,sex,and the Socio-demographic Index(SDI)level.The association between the attributable etiology of PLC and socioeconomic development status,represented using the SDI,was described.The attributable etiology of PLC included hepatitis B,hepatitis C,alcohol use,and nonalcoholic steatohepatitis.The association between the attributable etiology of PLC and SDI was further stratified by sex and geographical location.A confidence analysis was also performed based on bootstrap draw.RESULTS The age-standardized incidence rate of PLC was 6.5[95%confidence intervals(CI):5.9-7.2]per 100000 person-years,which decreased by-27.5%(-37.0 to-16.6)from 1990 to 2019.Several countries located in East Asia,South Asia,West Africa,and North Africa shouldered the heaviest burden of PLC in 2019.In terms of incidence rates,the first leading underlying cause of PLC identified was hepatitis B,followed by hepatitis C,alcohol use,and nonalcoholic steatohepatitis.Regarding stratification using the SDI,the incidence rate of PLC was the highest for high and middle SDI locations.Further,the leading attributable etiologies of PLC were hepatitis B for the middle and high middle SDI locations while hepatitis C and nonalcoholic steatohepatitis for the high SDI locations.CONCLUSION The pronounced association between socioeconomic development status and PLC burden indicates socioeconomic development status affects attributable etiologies for PLC.GBD 2019 data are valuable for policymakers implementing PLC cost-effective interventions.

摘要： BACKGROUND Alcohol consumption is a known modifiable risk factor for atrial fibrillation.The association,however,might differ according to gender.We investigated gender-specific associations between alcohol consumption and incident atrial fibrillation in an elderly Chinese population.METHODS Our study participants were elderly residents(≥65 years)recruited from five community health centers in the urban area of Shanghai(n=6,618).Alcohol intake was classified as never drinkers and current light-to-moderate(<40 g/day)and heavy drinkers(≥40 g/day).Atrial fibrillation was detected by a 30-s single-lead electrocardiography(ECG,AliveCor®Heart Monitor)and further evaluated with a regular 12-lead ECG.RESULTS During a median of 2.1 years(interquartile range:2.0−2.2)follow-up,the incidence rate of atrial fibrillation was 1.10%in all study participants.It was slightly but non-significantly higher in men(n=2849)than women(n=3769,1.30%vs.0.96%,P=0.19)and in current drinkers(n=793)than never drinkers(n=5825,1.64%vs.1.03%,P=0.12).In both unadjusted and adjusted analyses,there was interaction between sex and current alcohol intake in relation to the incidence of atrial fibrillation(P<0.0001).After adjustment for confounding factors,current drinkers had a significantly higher incidence rate of atrial fibrillation than never drinkers in women(12.96%[7/54]vs.0.78%[29/3715],adjusted odds ratio[OR]=10.25,95%confidence interval[CI]:3.54−29.67,P<0.0001),but not in men(0.81%[6/739]vs.1.47%[31/2110],OR=0.62,95%CI:0.25−1.51,P=0.29).CONCLUSIONS Our study showed a significant association between alcohol intake and the incidence of atrial fibrillation in elderly Chinese women,but not men.

摘要： The prevalence of alcoholic liver disease and non-alcoholic liver disease patients has nearly doubled over the past decades worldwide. Alcoholic liver disease among patients with chronic liver disease has increased with arisen due to alcohol consumption and obesity. The diagnosis plays a crucial role in treating such conditions based on the stages of liver functioning. The elevated liver enzymes are the key characterizing of identifying the alcoholic liver disease (ALD) and NAFLD. Later on, there is a progression of the disease conditions by developing fibrosis and cirrhosis, leading to liver carcinoma. The other state, steatohepatitis, is associated with an increase in liver-related and can lead to mortality. Risk factors for both diseases are growing, leading to various complications in health. There is no specific treatment up to date for these conditions, but statins play a crucial role in managing several liver disease conditions. The commonly used drug is hydroxymethylglutaryl coenzyme A (HMG Co-A) reductase inhibitors. It is also known as statins, which help normalize liver enzymes in patients with elevated plasma aminotransferases. As a result, external liver damage is considered safe for the liver as the Statin medication at low to moderate dose usage. OBJECTIVES: The main scope of this review is to study the various factors like pharmacological actions, adverse events, and biochemical and liver cell imaging results in patients with ALD and NAFLD. The different types of statins used in alcoholic and non-alcoholic patients’ clinical data for the safety of the statin therapy were concluded in this review. Fatty liver changes of both liver disease conditions were studied using different drugs. The other liver enzymes like Alanine transaminase (ALT), Aspartate transaminase (AST), Gamma-glutamyl Transferase (GGT), and the effectiveness of Statin therapy are considered vital concepts in this review.

摘要： Background and Objective: Chronic heavy alcohol consumption and daily cigarette smoking are the most prevalent substance use problems in the U.S., including Veterans. Excessive alcohol use causes neurocognitive and behavioral deficits that can be linked to neurodegeneration. Similarly, preclinical and clinical data suggest that smoking also leads to brain atrophy. This study examines the differential and additive effects of alcohol and cigarette smoke (CS) exposures on cognitive-behavioral function. Methods: A 4-way experimental model of chronic alcohol and CS exposures was generated using 4-week-old male and female Long Evans rats that were pair-fed with Lieber-deCarli isocaloric liquid diets containing 0% or 24% ethanol for 9 weeks. Half of the rats in the control and ethanol groups were exposed to CS for 4 hours/day and 4 days/week for 9 weeks. All rats were subjected to Morris Water Maze, Open Field, and Novel Object Recognition testing in the last experimental week. Results: Chronic alcohol exposure impaired spatial learning as shown by significantly increased latency to locate the platform, and it caused anxiety-like behavior marked by the significantly reduced percentage of entries to the center of the arena. Chronic CS exposure impaired recognition memory as suggested by significantly less time spent at the novel object. Combined exposures to alcohol and CS did not show any significant additive or interactive effect on cognitive-behavioral function. Conclusion: Chronic alcohol exposure was the main driver of spatial learning, while the effect of secondhand CS exposure was not robust. Future studies need to mimic direct CS exposure effects in humans.

摘要： A magnetically recoverable Ru Co bimetallic catalyst was reported for the catalytic hydrogenation of furfural to furfuryl alcohol under ambient H_(2) pressure.The magnetic catalyst was prepared by H_(2) treatment of the Ru Co composite precursor from a facile one-pot hydrolysis of Co and Ru salts by NaBH_(4) solution.This catalyst can totally convert furfural to 98–100% furfuryl alcohol at 120°C under 1 bar H_(2) in isopropanol or water using only molecular H_(2) as hydrogen source.Moreover,the catalyst showed excellent stability during recycling test and can be easily and completely recovered by magnet from reaction solution.The influence of Ru/Co ratio and H_(2)-treatment temperature was studied,which were shown to be important for the structural evolution and the metal interaction in Ru Co active sites,based on the comprehensive characterizations including XRD,TGA,TEM,XPS,H_(2)-TPR,CO adsorbed DRIFT-IR.It was demonstrated that the cooperative Ru~0–Co~0 bimetallic active sites in strong interaction can significantly promote activity and selectivity of the catalyst due to an enhanced adsorption and activation of furfural and H_(2),and simultaneously created a strong magnetism in the Ru Co catalyst for simple physical separation.

摘要： Sulfonic acid functionalized titanate nanotubes were prepared by the sulphonation reaction of hydrothermally synthesized TiO_(2) nanotubes(TNTs) using chlorosulfonic acid as the sulfating agent.The as-prepared catalysts were characterized by fourier transform infrared(FT-IR)spectroscopy,transmission electron microscopy(TEM),scanning electron microscopy-energy dispersive X-ray spectroscopy(SEM-EDX),Xray diffraction(XRD) analysis,thermogravimetry-differential thermal gravimetry(TG-DTG) and X-ray photoelectron spectroscopy(XPS)techniques.The characterization results revealed that the catalysts retained the tubular structure of the TNTs and possessed a large number of active sulfonic acid sites.The catalytic performance of the catalysts for the synthesis of n-butyl levulinate was investigated via the alcoholysis of biomass-derived furfuryl alcohol under atmospheric pressure.The effects of the reaction factors such as the catalyst dosage,reaction time,and temperature on the alcoholysis of the furfuryl alcohol were systematically studied.Under mild conditions,about 79.9% yield of n-butyl levulinate was achieved.In addition,the catalysts showed a stable catalytic performance after four consecutive cycles.Furthermore,no leaching of the active species was observed during the hot filtration testing,which can be attributed to the covalently linked –SO_(3)H groups on the TNTs surface.In addition,the opened tubular nanostructure of the catalyst and the introduced strong Br?nsted acid sites exhibited synergistic effects,which facilitated the selective conversion of the furfuryl alcohol to butyl levulinate.
