The rule for the crystallization of the above three families of microporous aluminophosphates was summarized and the effects of organic amine, P/Al ratio, sources of aluminum and phosphorous and temperature on the resulted structures were investigated.

Protective mechanism of Coprinus comatus polysaccharide on acute alcoholic liver injury in mice,the metabolomics and gut microbiota investigation

Coprinus comatus polysaccharide(CCP)has significant hepatoprotective effect.To explore hepatoprotective mechanism of CCP,the study analyzed preventive effect of CCP on acute alcoholic liver injury in mice by histopathological examination and biochemical analysis.Simultaneously,hepatoprotective mechanism was also analyzed in conjunction with metabolomics and proliferation of gut microbiota.The results showed that CCP significantly decreased alanine aminotransferase(ALT),aspartate aminotransferase(AST)and triglyceride(TG)levels in serum of alcoholic liver disease(ALD)mice.Histopathological examination showed that CCP can significantly improve liver damage.Metabolomics results showed that there were significant differences in the level of metabolites in liver tissue of control group,ALD group and CCP group,including taurine,xanthosine,fumaric acid and arachidonic acid,among others.Metabolites pathways analysis showed that hepatoprotective effect of CCP was related to energy metabolism,biosynthesis of unsaturated fatty acids,amino acids metabolism and lipid metabolism.Additionally,CCP inhibited an increase in the number of Clostridium perfringens,Enterobacteriaceae and Enterococcus,and a decrease in the number of Lactobacillus and Bifidobacterium in the gut of ALD mice.All these findings suggested that CCP treatment reversed the phenotype of ethanol-induced liver injury and the associated metabolites pathways.

Curcumin delivery nanoparticles based on Maillard reaction of Haematococcus pluvialis protein/galactose for alleviating acute alcoholic liver damage

The aim of this study is to investigate the feasibility of Maillard reaction products of Haematococcus pluvialis protein and galactose(HPP-GAL)for improving the bioactivities of curcumin(CUR)for alleviating alcoholic liver damage.CUR was embedded into HPP-GAL nanoparticles by the self-assembly of hydrogen bonding and hydrophobic interaction with the particle size around 200 nm.HPP-GAL enhanced the encapsulation efficiency and loading amount of CUR with the value of(89.21±0.33)%and(0.500±0.004)%,respectively.The stabilities of CUR under strong acid,salt ion stability and ultraviolet irradiation conditions were improved by the encapsulation.HPP-GAL-CUR nanoparticles exhibited excellent concentration-dependent in vitro antioxidant activities including DPPH and ABTS scavenging rates,and better protective effect on CUR against gastric acid environment as well as longer release of CUR in simulated intestinal fluid.In addition,the HPPGAL-CUR delivery system possessed liver targeting property due to the existence of GAL,which could effectively alleviate the alcohol-induced liver damage and the inflammation indexes by inhibiting the oxidative stress.Therefore,HPP-GAL-CUR nanoparticles might be a potential candidate system for the prevention of alcoholic liver damage in the future.

Peroxisome proliferator-activated receptor agonists:A new hope towards the management of alcoholic liver disease

In this editorial,we examine a paper by Koizumi et al,on the role of peroxisome proliferator-activated receptor(PPAR)agonists in alcoholic liver disease(ALD).The study determined whether elafibranor protected the intestinal barrier and reduced liver fibrosis in a mouse model of ALD.The study also underlines the role of PPARs in intestinal barrier function and lipid homeostasis,which are both affected by ALD.Effective therapies are necessary for ALD because it is a critical health issue that affects people worldwide.This editorial analyzes the possibility of PPAR agonists as treatments for ALD.As key factors of inflammation and metabolism,PPARs offer multiple methods for managing the complex etiology of ALD.We assess the abilities of PPARα,PPARγ,and PPARβ/δagonists to prevent steatosis,inflammation,and fibrosis due to liver diseases.Recent research carried out in preclinical and clinical settings has shown that PPAR agonists can reduce the severity of liver disease.This editorial discusses the data analyzed and the obstacles,advantages,and mechanisms of action of PPAR agonists for ALD.Further research is needed to understand the efficacy,safety,and mechanisms of PPAR agonists for treating ALD.

Elafibranor:A promising treatment for alcoholic liver disease,metabolic-associated fatty liver disease,and cholestatic liver disease

Clinical review and literature analysis of hepatic epithelioid angiomyolipoma in alcoholic cirrhosis: A case report

BACKGROUND Hepatic epithelioid angiomyolipoma(HEA)has a low incidence and both clinical manifestations and imaging lack specificity.Thus,it is easy to misdiagnose HEA as other tumors of the liver,especially in the presence of liver diseases such as hepatitis cirrhosis.This article reviewed the diagnosis and treatment of a patient with HEA and alcoholic cirrhosis,and analyzed the literature,in order to improve the understanding of this disease.CASE SUMMARY A 67-year-old male patient with a history of alcoholic cirrhosis was admitted due to the discovery of a space-occupying lesion in the liver.Based on the patient’s history,laboratory examinations,and imaging examinations,a malignant liver tumor was considered and laparoscopic partial hepatectomy was performed.Postoperative pathology showed HEA.During outpatient follow-up,the patient showed no sign of recurrence.CONCLUSION HEA is difficult to make a definite diagnosis before surgery.HEA has the poten-tial for malignant degeneration.If conditions permit,surgical treatment is recom-mended.

Protective effect of Solanum Nigrum Linn green fruit ethanolic extract on alcoholic liver injury in mice

Alcoholic liver injury is a liver disease caused by excessive alcohol consumption,which can lead to chronic liver disease death.Solanum Nigrum Linn taste bitter,cold,has the effect of clearing heat and detoxification,promoting blood and detumescence.Solanum Nigrum Linn fruit contains a variety of antioxidant enzymes,can remove the body produced by aerobic metabolism harmful substances.In this paper,a model of alcohol-induced liver injury in C57BL/6 mice was established to evaluate the protective effect of Solanum Nigrum Linn green fruit(SNGF)ethanolic extract on alcohol-induced liver injury.H&E staining and oil red O(ORO)staining showed that hepatic lobules were clearly demarcated,vacuoles were significantly reduced and lipid droplets were reduced in SNGF ethanolic extract treatment group.Serum levels of TC,TG,LDH,TBA,AKP,ALT and AST were decreased in the SNGF ethanolic extract treatment group,and SNGF ethanolic extract could clear reactive oxygen species(ROS)in time.MDA content was signifi cantly decreased after SNGF ethanolic extract treatment,while superoxide dismutase(SOD)and GSH-Px contents were increased after SNGF ethanolic extract treatment.These results suggest that SNGF ethanolic extract has a protective effect on alcohol-induced liver injury.

Non-alcoholic fatty liver disease and thyroid dysfunction:A systematic review

Thyroid hormones are totally involved in the regulation of body weight, lipid metabolism, and insulin resistance. Therefore it is anticipated that thyroid hormones may have a role in the pathogenesis of non alcoholic fatty liver disease(NAFLD) and non alcoholic steatohepatitis(NASH). In this study, we reviewed the current literature on the association between thyroid dysfunction and NAFLD/NASH. A search for English language medical literature reporting an association between thyroid dysfunction and NAFLD/NASH in humans was conducted across PubMed, ISI Web of Science, and Scopus in August, 2013. Out of 140 studies initially identified through the search, 11 relevant articles were included in the final review. Thyroid dysfunctions in the form of overt or subclinical hypothyroidism are prevalent among patients with NAFLD/NASH. Hypothyroidism appears to be an independent risk factor for NAFLD/NASH in some studies; however, other newly published studies failed to find such anassociation. The results of the studies on the role of thyroid abnormalities in NAFLD/NASH are inconsistent, and further research is recommended to determine the relationship between hypothyroidism and NAFLD/NASH and the underlying mechanisms.

Nonalcoholic fatty liver disease and the renin-angiotensin system:Implications for treatment

Nonalcoholic fatty liver disease(NAFLD) is the commonest liver disease in Western countries.Treatment of NAFLD is currently based on lifestyle measures and no effective pharmacologic treatment is available so far.Emerging evidence,mainly from animal studies,suggests that the renin-angiotensin-aldosterone system may be of major importance in the pathogenesis of NAFLD and indicates that angiotensin-converting enzyme inhibitors(ACE-I) and angiotensin receptor blockers(ARBs) as a potentially useful therapeutic approach.However,data from human studies are limited and contradictory.In addition,there are few randomized controlled trials(RCTs) on the effects of ACE-I or ARB in patients with NAFLD and most data are from retrospective studies,pilot prospective studies and post hoc analyses of clinical trials.Accordingly,more and larger RCTs are needed to directly assess the effectiveness of ACE-I and ARBs in NAFLD.

Assessment of scoring systems for acute-on-chronic liver failure at predicting short-term mortality in patients with alcoholic hepatitis

AIM To assess the performance of proposed scores specific for acute-on-chronic liver failure in predicting shortterm mortality among patients with alcoholic hepatitis.METHODS We retrospectively collected data from 264 patients with clinically diagnosed alcoholic hepatitis from January to December 2013 at 21 academic hospitals in Korea. The performance for predicting short-term mortality was calculated for Chronic Liver FailureSequential Organ Failure Assessment(CLIF-SOFA), CLIF Consortium Organ Failure score(CLIF-C OFs), Maddrey'sdiscriminant function(DF), age, bilirubin, international normalized ratio and creatinine score(ABIC), Glasgow Alcoholic Hepatitis Score(GAHS), model for end-stage liver disease(MELD), and MELD-Na.RESULTS Of 264 patients, 32(12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86(0.81-0.90), 0.89(0.84-0.92), 0.79(0.74-0.84), 0.78(0.72-0.83), 0.81(0.76-0.86), 0.83(0.78-0.88), and 0.83(0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d mortality.CONCLUSION CLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis.

System to Control Upright Posture with Alcoholic Intake

Equilibrium function in the cerebellum （vestibulo-cerebellar system） can deteriorate under the influence of alcohol. In the Romberg posture, the center of gravity, which was measured every 50 ms by stabilometry, appeared to shift with alcohol ingestion. In the previous study, a locus in the center of gravity （stabilogram） was converted to values of statistical indices such as area of sway, total locus length, sparse density, and locus length per unit area, although these indices could not always distinguish between the stabilograms sampled from seven healthy young males in sober and intoxicated states. This measurement was made with an AMTI force plate. In this study, ＂translation error＂ was estimated in a d-dimensional embedding space in order to compare stabilograms recorded before and after the ingestion of doubly diluted brandy in 30 s （1 ≤ d ≤ 10）. The authors succeeded in validating stochastic differential equations as a mathematical model of the body sway. Although the postural control system shows different patterns in the lateral and anterior-posterior directions, the randomness in the model was preserved after alcohol intake and significantly increased in the medial/lateral direction. Visual information referred by the postural conlrol system when standing might be interfered by the effects of intoxication, which was regarded as disturbance. The possibility of detecting alcohol-ingestion-induced reduction of the equilibrium function and its recovery process are also suggested in this paper. This method is considered to be useful to diagnose the disorders of the vestibulo-cerebellar system.

Comparison between metabolic-associated fatty liver disease and nonalcoholic fatty liver disease:From nomenclature to clinical outcomes

As a result of the obesity epidemic,Nonalcoholic fatty liver disease(NAFLD)and its complications have increased among millions of people.Consequently,a group of experts recommended changing the term NAFLD to an inclusive terminology more reflective of the underlying pathogenesis;metabolic-associated fatty liver disease(MAFLD).This new term of MAFLD has its own disease epidemiology and clinical outcomes prompting efforts in studying its differences from NAFLD.This article discusses the rationale behind the nomenclature change,the main differences,and its clinical implications.

Ginsenoside Rk2, a dehydroprotopanaxadiol saponin, alleviates alcoholic liver disease via regulating NLRP3 and NLRP6 inflammasome signaling pathways in mice

Heavy alcohol consumption results in alcoholic liver disease(ALD)with inadequate therapeutic options.Here,we first report the potential beneficial effects of ginsenoside Rk2(Rk2),a rare dehydroprotopanaxadiol saponin isolated from streamed ginseng,against alcoholic liver injury in mice.Chronic-plus-single-binge ethanol feeding caused severe liver injury,as manifested by significantly elevated serum aminotransferase levels,hepatic histological changes,increased lipid accumulation,oxidative stress,and inflammation in the liver.These deleterious effects were alleviated by the treatment with Rk2(5 and 30 mg/kg).Acting as an nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3(NLRP3)inhibitor,Rk2 ameliorates alcohol-induced liver inflammation by inhibiting NLRP3 inflammasome signaling in the liver.Meanwhile,the treatment with Rk2 alleviated the alcohol-induced intestinal barrier dysfunction via enhancing NLRP6 inflammasome in the intestine.Our findings indicate that Rk2 is a promising agent for the prevention and treatment of ALD and other NLPR3-driven diseases.

Molecular mechanism of Solanum Nigrum Linn in alcoholic liver damage based on network pharmacology and molecular docking

Solanum Nigrum Linn,the purpose of this study was to characterize the chemical components of the extract of Solanum Nigrum Linn by LC-MS/MS,and to identify 29 compounds by positive and negative total ion flow maps.The potential mechanism of action of Solanum Nigrum Linn in treating alcoholic liver injury was investigated by means of network pharmacology and molecular docking.A total of 288 component target genes and 1010 disease target genes were obtained,and 98 intersection targets and 7 core targets were obtained after the intersection of the two genes.GO analysis and KEGG analysis respectively obtained 20 signaling pathways such as anti-inflammation and anti-apoptosis.The results of molecular docking showed that the blood components could successfully dock with the target proteins of the disease such as GAPDH,IL6,SRC,EGFR and ESR1.This study provided a scientific basis for the development and application of Solanum Nigrum Linn.

Construction and evaluation of an alcohol vapor chamber system

An increasing number of studies demonstrated that alcohol vapor chamber is an effective way to model physical signs of alcohol use disorders. Although researchers are developing different vapor chambers to study chronic alcohol exposure model worldwide, few studies build and modify their own vapor chambers in China.Here, we designed and established an alcohol vapor chamber system for small animals. We described a paradigm showing how to control and monitor alcohol concentration in whole system. The vapor chamber system with several advantages including accommodating up to ten standard mouse cages. Furthermore, the system was tested by evaluating the blood alcohol concentration and neuron injury in mice. Importantly, the alcohol withdrawal after vapor exposure caused motor coordination impairment, anxiolytic-and depression-like behavior. Finally, the Nmethyl-D-aspartate receptor(NMDAR)-mediated glutamatergic transmissions in the medial prefrontal cortex was changed after alcohol vapor exposure-induced behaviors. The frequency and amplitude of spontaneous excitatory postsynaptic currents between control and alcohol groups were not different, suggesting that alcohol exposureinduced behaviors are associated with the change in NMDAR response. Taken together, the new alcohol vapor chamber system was constructed, which would help to research the relationship between the stable alcohol exposure and withdrawal behaviors and to study chronic alcohol exposure-induced disorders in China.

Hospitalizations for alcoholic liver disease during the COVID-19 pandemic increased more for women,especially young women,compared to men

BACKGROUND Alcoholic liver disease(ALD)remains one of the major indications for liver transplantation in the United States and continues to place a burden on the national healthcare system.There is evidence of increased alcohol consumption during the coronavirus disease 2019(COVID-19)pandemic,and the effect of this on the already burdened health systems remains unknown.AIM To assess the trends for ALD admissions during the COVID-19 pandemic,and compare it to a similar pre-pandemic period.METHODS This retrospective study analyzed all admissions at a tertiary health care system,which includes four regional hospitals.ALD admissions were identified by querying a multi-hospital health system’s electronic database using ICD-10 codes.ALD admissions were compared for two one-year periods;pre-COVID-19 from April 2019 to March 2020,and during-COVID-19 from April 2020 to March 2021.Data were analyzed using a Poisson regression model and admission rates were compared using the annual quarterly average for the two time periods,with stratification by age and gender.Percent increase or decrease in admissions from the Poisson regression model were reported as incident rate ratios.RESULTS One thousand three hundred and seventy-eight admissions for ALD were included.80.7%were Caucasian,and 34.3%were female.An increase in the number of admissions for ALD during the COVID-19 pandemic was detected.Among women,a sharp rise(33%)was noted in those below the age of 50 years,and an increase of 22%in those above 50 years.Among men,an increase of 24%was seen for those below 50 years,and a 24%decrease in those above 50 years.CONCLUSION The COVID-19 pandemic has had widespread implications,and an increase in ALD admissions is just one of them.However,given that women are often prone to rapid progression of ALD,this finding has important preventive health implications.

Physico-chemical parameters for the assembly of moxifloxacin hydrochloride and cetyltrimethylammonium chloride mixture in aqueous and alcoholic media

The aggregation behavior of the mixture of cetyltrimethylammonium chloride(CTAC), a cationic surfactant, and moxifloxacin hydrochloride(MFH), a fourth-generation fluoroquinolone antibiotic drug, has been studied using the conductivity technique in aqueous and alcoholic(EtOH, 1-PrOH, and 2-BuOH)media. The study was performed at several temperatures between 298.15 and 323.15 K at 5 K intervals.The assembly has been characterized by evaluating the micellar parameters, such as the critical micelle concentration(CMC) and the counter ion binding(β), of the CTAC + MFH mixture. The values of the CMC for the assembly of the CTAC + MFH mixture were reliant on the composition of alcohols in the mixed solvents and the temperature. The CMC values of the CTAC + MFH mixture increased with increasing temperature;that is, assembly was delayed by increased temperature. The micellization of the CTAC + MFH mixed system was delayed in alcoholic media. The observed-ΔG0mvalues for the association of the CTAC + MFH mixed system demonstrated a spontaneous aggregation process under all study conditions.Based on the-ΔH^(0)_(m) and +ΔS^(0)_(m) values, the association of the CTAC + MFH mixture is exothermic and the interaction forces acting between the CTAC and MFH species are hydrophobic, ion–dipole, and electrostatic interactions. The transfer properties and enthalpy–entropy compensation were also assessed and described comprehensively.

Optimization of Extraction Conditions of Pomegranate Peel Polyphenols and Its Protective Effect on Acute Alcoholic Liver Injury in Mice

[Objectives]This study was conducted to explore the optimization of ultrasonic-assisted organic solvent extraction of pomegranate peel polyphenols(PPPs),and to study the protective effect of PPPs on acute alcoholic liver injury in mice.[Methods]The optimal extraction conditions of PPPs were determined by single factor and orthogonal experiments,and an acute alcoholic liver injury model in mice was established.Bifendate was used as the positive control group to investigate the protective effect of low,medium and high doses of PPPs on acute alcoholic liver injury.[Results]The optimum extraction process parameters were followed as 60%ethanol concentration,solid-liquid ratio of 1:40(w/v),extraction temperature of 50℃,and extraction time of 1.5 h,and the yield was 1.42%.The results of animal experiments showed that PPPs could effectively reduce the degree of alcoholic liver injury in mice,reduce the levels of serum alanine aminotransferase(ALT)and aspartate aminotransferase(AST),and reduce the inflammation and necrosis of liver tissue in mice.Meanwhile,the total polyphenols from pomegranate peel also significantly reduced the expression levels of malondialdehyde(MDA),tumor necrosis factor(TNF-α)and interleukin-6(IL-6)in mice,and increased the levels of superoxide dismutase(SOD)and reduced glutathione(GSH)in liver tissue of mice,indicating its antioxidant and anti-inflammatory effects,further illustrating its protective effect on alcoholic liver injury.[Conclusions]PPPs could reduce the expression levels of TNF-α,IL-6 and MDA in mice,and increase the expression levels of SOD and GSH to achieve the protective effect on acute alcoholic liver injury in mice.This study will provide new ideas for the development of new anti-alcoholic liver injury drug resources.
