Elafibranor alleviates alcohol-related liver fibrosis by restoring intestinal barrier function

We discuss the article by Koizumi et al published in the World Journal of Gastroenterology.Our focus is on the therapeutic targets for fibrosis associated with alcohol-related liver disease(ALD)and the mechanism of action of elafibranor(EFN),a dual agonist of peroxisome proliferator-activated receptorα(PPARα)and peroxisome PPARδ(PPARδ).EFN is currently in phase III clinical trials for the treatment of metabolic dysfunction-associated fatty liver disease and primary biliary cholangitis.ALD progresses from alcoholic fatty liver to alcoholic steatohepatitis(ASH),with chronic ASH eventually leading to fibrosis,cirrhosis,and,in some cases,hepatocellular carcinoma.The pathogenesis of ALD is driven by hepatic steatosis,oxidative stress,and acetaldehyde toxicity.Alcohol consumption disrupts lipid metabolism by inactivating PPARα,exacerbating the progression of ALD.EFN primarily activates PPARα,promoting lipolysis andβ-oxidation in ethanol-stimulated HepG2 cells,which significantly reduces hepatic steatosis,apoptosis,and fibrosis in an ALD mouse model.Additionally,alcohol disrupts the gut-liver axis at several interconnected levels,contributing to a proinflammatory environment in the liver.EFN helps alleviate intestinal hyperpermeability by restoring tight junction protein expression and autophagy,inhibiting apoptosis and inflammatory responses,and enhancing intestinal barrier function through PPARδactivation.

Effects of elafibranor on liver fibrosis and gut barrier function in a mouse model of alcohol-associated liver disease

BACKGROUND Alcohol-associated liver disease(ALD)is a leading cause of liver-related morbidity and mortality,but there are no therapeutic targets and modalities to prevent ALD-related liver fibrosis.Peroxisome proliferator activated receptor(PPAR)α and δ play a key role in lipid metabolism and intestinal barrier homeostasis,which are major contributors to the pathological progression of ALD.Meanwhile,elafibranor(EFN),which is a dual PPARαand PPARδagonist,has reached a phase III clinical trial for the treatment of metabolic dysfunctionassociated steatotic liver disease and primary biliary cholangitis.However,the benefits of EFN for ALD treatment is unknown.AIM To evaluate the inhibitory effects of EFN on liver fibrosis and gut-intestinal barrier dysfunction in an ALD mouse model.METHODS ALD-related liver fibrosis was induced in female C57BL/6J mice by feeding a 2.5% ethanol(EtOH)-containing Lieber-DeCarli liquid diet and intraperitoneally injecting carbon tetrachloride thrice weekly(1 mL/kg)for 8 weeks.EFN(3 and 10 mg/kg/day)was orally administered during the experimental period.Histological and molecular analyses were performed to assess the effect of EFN on steatohepatitis,fibrosis,and intestinal barrier integrity.The EFN effects on HepG2 lipotoxicity and Caco-2 barrier function were evaluated by cell-based assays.RESULTS The hepatic steatosis,apoptosis,and fibrosis in the ALD mice model were significantly attenuated by EFN treatment.EFN promoted lipolysis and β-oxidation and enhanced autophagic and antioxidant capacities in EtOH-stimulated HepG2 cells,primarily through PPARαactivation.Moreover,EFN inhibited the Kupffer cell-mediated inflammatory response,with blunted hepatic exposure to lipopolysaccharide(LPS)and toll like receptor 4(TLR4)/nuclear factor kappa B(NF-κB)signaling.EFN improved intestinal hyperpermeability by restoring tight junction proteins and autophagy and by inhibiting apoptosis and proinflammatory responses.The protective effect on intestinal barrier function in the EtOH-stimulated Caco-2 cells was predominantly mediated by PPARδ activation.CONCLUSION EFN reduced ALD-related fibrosis by inhibiting lipid accumulation and apoptosis,enhancing hepatocyte autophagic and antioxidant capacities,and suppressing LPS/TLR4/NF-κB-mediated inflammatory responses by restoring intestinal barrier function.

Abnormal liver function tests associated with severe rhabdomyolysis

Rhabdomyolysis is a syndrome of skeletal muscle injury with release of cellular constituents such as potassium,phosphate,urate and intracellular proteins such as myoglobin into the circulation,which may cause complications including acute kidney injury,electrolyte disturbance and cardiac instability.Abnormal liver function tests are frequently observed in cases of severe rhabdomyolysis.Typically,there is an increase in serum aminotransferases,namely aspartate aminotransferase and alanine aminotransferase.This raises the question of liver injury and often triggers a pathway of investigation which may lead to a liver biopsy.However,muscle can also be a source of the increased aminotransferase activity.This review discusses the dilemma of finding abnormal liver function tests in the setting of muscle injury and the potential implications of such an association.It delves into some of the clinical and experimental evidence for correlating muscle injury to raised aminotransferases,and discusses pathophysiological mechanisms such as oxidative stress which may cause actual liver injury.Serum aminotransferases lack tissue specificity to allow clinicians to distinguish primary liver injury from muscle injury.This review also explores potential approaches to improve the accuracy of our diagnostic tools,so that excessive or unnecessary liver investigations can be avoided.

Could quantitative liver function tests gain wide acceptance among hepatologists?

It has been emphasized that the assessment of residual liver function is of paramount importance to determine the following： severity of acute or chronic liver diseases independent of etiology; long-term prognosis; step-bystep disease progression; surgical risk; and efficacy of antiviral treatment. The most frequently used tools are the galactose elimination capacity to asses hepatocyte cytosol activity, plasma clearance of indocyanine green to assess excretory function, and antipyrine clearance to estimate microsomal activity. However, a widely accepted liver test （not necessarily a laboratory one） to assess quantitative functional hepatic reserve still needs to be established, although there have been various proposals. Furthermore, who are the operators that should order these tests？ Advances in analytic methods are expected to allow quantitative liver function tests to be used in clinical practice.

Measurement of hepatic functional mass by means of ^(13)C-methacetin and ^(13)C-phenylalanine breath tests in chronic liver disease: Comparison with Child-Pugh score and serum bile acid levels

AIM: To evaluate and compare the clinical usefulness of 13C-phenylalanine and 13C-methacetin breath tests in quantitating functional hepatic mass in patients with chronic liver disease and to further compare these results with those of conventional tests, Child-Pugh score and serum bile acid levels.METHODS: One hundred and forty patients (50 HCV-related chronic hepatitis, 90 liver cirrhosis patients) and 40 matched healthy controls were studied. Both breath test and routine liver test, serum levels of cholic and chenodeoxycholic acid conjugates were evaluated.RESULTS: Methacetin breath test, expressed as 60 min cumulative percent of oxidation, discriminated the hepatic functional capacity not only between controls and liver disease patients, but also between different categories of chronic liver disease patients. Methacetin breath test was correlated with liver function tests and serum bile acids.Furthermore, methacetin breath test, as well as serum bile acids, were highly predictive of Child-Pugh scores. The diagnostic power of phenylalanine breath test was always less than that of methacetin breath test.CONCLUSION: Methacetin breath test represents a safe and accurate diagnostic tool in the evaluation of hepatic functional mass in chronic liver disease patients.

Influence of diet intake on liver function test

AIM To study the influence of diet intake on the result of liver function test. METHODS Blood samples from liver diseases ( n =100) and non liver diseases ( n =100) were taken at 07:00 in the morning (fasting state) and two hours after meal. Using Hitach 7150 automatic biochemistry analyser, ten liver function indexes (SB, TTT, ALT, AST, ALP, LDH, γ-GT, SP, A and G) were examined. RESULTS According to the SAS software system the differences were not significant between fasting state and after meal ( P =0 476-0 978). CONCLUSION Liver function test can be performed after meal.

Protective effect of probiotics on intestinal barrier function in malnourished rats after liver transplantation

BACKGROUND: Most patients waiting for liver transplantation have end-stage liver diseases with malnutrition, which is prone to induce intestinal barrier dysfunction after liver transplantation. We aimed to study the effect of probiotics on intestinal barrier function in malnourished rats following liver transplantation with long-term antibiotics. METHODS: Twelve Lewis rats were selected as donors. Twelve BN rats, which served as recipients, were subjected to malnutrition by semi-starvation for 4-5 weeks. They were randomly divided into two groups: a control group which received phosphate-buffered saline and a probiotics group which received Bifidobacterium and Lactobacillus. All recipients were injected with intramuscular imipenem and subcutaneous cyclosporine A. Furthermore, six normal BN rats without any drugs or operations served as a normal group. Eight days after operation, all rats were sacrificed for examination of the following parameters: serum levels of endotoxin and TNF-α, bacterial translocation, intestinal microflora, ileocecal sIgA, lymphocyte numbers, and phenotypes (CD4, CD8, αβTCR, γδTCR)ofPeyer’spatches. RESULTS: In recipients subjected to malnutrition, weight decreased by 20% and they survived until 8 days after operation. Compared with the normal group, all recipients on postoperative day 8 showed increased levels of serum endotoxin and TNF-α as well as increased counts oftranslocated bacteria. Meanwhile, there were decreases in counts of Bifidobacterium and Lactobacillus in the ileocecum, sIgA concentration, and lymphocytes of Peyer’s patches. Moreover, partial alteration in lymphocyte phenotypes was evidenced by elevated ratios of CD8 + and γδTCR + lymphocytes. In contrast, compared to the control group, supplementation with probiotics reduced the levels of serum endotoxin, TNF-α and bacterial translocation, increased the counts of Bifidobacterium and Lactobacillus, the concentration of sIgA and lymphocytes of Peyer’s patches, and also slightly restored the alteration of lymphocyte phenotypes. CONCLUSION: Supplementation with probiotics including Bifidobac-terium and Lactobacillus promoted partial restoration of intestinal microflora and improved intestinal barrier function in malnourished rats after liver transplantation with long-term use of antibiotics.

Enteral supplementation with glycyl-glutamine improves intestinal barrier function after liver transplantation in rats

BACKGROUND:Most patients after liver transplantation (LT) suffer from intestinal barrier dysfunction.Glycyl-glutamine (Gly-Gln) by parenteral supplementation is hydrolyzed to release glutamine,which improves intestinal barrier function in intestinal injury.This study aimed to investigate the effect of GlyGln by enteral supplementation on intestinal barrier function in rats after allogenetic LT under immunosuppressive therapy.METHODS:Twelve inbred Lewis rats were selected randomly as donors,and 24 inbred Brown Norway (BN) rats as recipients of allogenetic LT.The recipients were divided into a control group (Ala,n=12) and an experimental group (Gly-Gln,n=12).In each group,6 normal BN rats were sampled for normal parameters on preoperative day 3.The 6 recipients in the control group received alanine (Ala) daily by gastric perfusion for 3 preoperative days and 7 postoperative days,and the 6 recipients in the experimental group were given Gly-Gln in the same manner.The 12 BN recipients underwent orthotopic LT under sterile conditions after a 3-day fast and were given immunosuppressive therapy for 7 days.They were harvested for sampling on postoperative day 8.The following parameters were assessed:intestinal mucosal protein content,mucosal ultrastructure,ileocecal sIgA content,portal plasma levels of endotoxin and TNF-α,and bacterial translocation.RESULTS:All recipients were alive after LT.On preoperative day 3,all parameters were similar in the two groups.On postoperative day 8,all parameters in the two groups were remarkably changed from those on preoperative day 3.However,compared to the Ala group,supplementation withGly-Gln increased the levels of intestinal mucosal protein and ileocecal sIgA,improved mucosal microvilli,and decreased portal plasma levels of endotoxin and TNF-α as well as bacterial translocation.CONCLUSION:Enteral supplementation with Gly-Gln improved intestinal barrier function after allogenetic LT in rats.

Six Minute Walk Test to assess functional capacity in chronic liver disease patients

AIM: To examine the utility of Six Minute Walk Test (6MWT) in patients with chronic liver disease (CLD). METHODS: Two hundred and fifty subjects between the ages of 18 and 80 (mean 47) years performed 6MWT and the Six Minute Walk Distance (6MWD) was measured. RESULTS: The subjects were categorized into four groups. Group A (n = 45) healthy subjects (control); group B (n = 49) chronic hepatitis B patients; group C (n = 54) chronic hepatitis C patients; group D (n = 98) liver cirrhosis patients. The four groups differed in terms of 6MWDs (P < 0.001). The longest distance walked was 421 ± 47 m by group A, then group B (390 ± 53 m), group C (357 ± 72 m) and group D (306 ± 111 m). The 6MWD correlated with age (r = -0.482, P < 0.01), hemoglobin (r = +0.373, P < 0.001) and albumin (r = +0.311, P < 0.001) levels. The Child-Pugh classification was negatively correlated with the 6MWD in cirrhosis (group D) patients (r = -0.328, P < 0.01). At the end of a 12 mo follow-up period, 15 of the 98 cirrhosis patients had died from disease complications. The 6MWD for the surviving cirrhotic patients was longer than for non-survivors (317 ± 101 vs 245 ± 145 m, P = 0.021; 95% CI 11-132). The 6MWD was found to be an independent predictor of survival (P = 0.024). CONCLUSION: 6MWT is a useful tool for assessing physical function in CLD patients. We suggest that 6MWD may serve as a prognostic indicator in patients with liver cirrhosis.

Liver function tests: Association with cardiovascular outcomes

An association between nonalcoholic fatty liver disease and cardiovascular disease has been repeatedly rep orted. Several studies have focused on levels of gammaglutamyltransferase (GGT) and alanine aminotransferase (ALT) in relation to cardiovascular outcomes. Evidence indicates that GGT may have a potential role for cardiovascular risk stratifi cation while the role of ALT for cardiac prognosis remains controversial. A conceptual framework that includes not only GGT and ALT but also markers of hepatocyte apoptosis such as cytokeratin-18 fragments should be developed.

Liver function tests and metabolic-associated fatty liver disease:Changes in upper normal limits,does it really matter?

BACKGROUND Metabolic-associated fatty liver disease(MAFLD)is the commonest cause of abnormal liver function tests(LFTs).Current upper normal of limit(UNL)of LFTs was derived from a“healthy”population,where undiagnosed MAFLD and viral hepatitis might be suspected.AIM To evaluated potential implications of changes in UNL of alanine aminotransferase(ALT)in MAFLD.METHODS We retrospectively assessed consecutive first referrals with a diagnosis of MAFLD from 2010 to 2017.The conventional UNL of ALT was 45 IU/L for men and 34 IU/L for women,while a low UNL of ALT was 30 IU/L for men and 19 IU/L for women.The UNL of aspartate aminotransferase(AST)was 40 IU/L.RESULTS Total 436 patients were enrolled;of these,288 underwent liver biopsy.Setting a lower UNL reduced the percentage of those with significant disease despite normal ALT;specifically,patients with advanced fibrosis(F≥F3)or definite“metabolic-associated steato-hepatitis(MASH)”(NAS≥5)within normal ALT decreased from 10%to 1%and from 28%to 4%respectively.However,the proportion of those with elevated ALT and no evidence of advanced fibrosis or“definite MASH”increased from 39%to 47%and from 3%to 19%.Overall,LFTs performed poorly in distinguishing“definite MASH”from simple steatosis(receiver operating characteristic areas under the curves 0.59 for ALT and 0.55 for AST).CONCLUSION Liver function tests might both under-and overestimate MASH-related liver disease.Reducing the UNL might not be beneficial and imply an increase in healthcare burden.Risk stratification in MAFLD should rely on a combination of risk factors,not on LFTs alone.

Short-term efficacy of microwave ablation in the treatment of liver cancer and its effect on immune function

BACKGROUND Hepatectomy is the first choice for treating liver cancer.However,inflammatory factors,released in response to pain stimulation,may suppress perioperative immune function and affect the prognosis of patients undergoing hepatectomies.AIM To determine the short-term efficacy of microwave ablation in the treatment of liver cancer and its effect on immune function.METHODS Clinical data from patients with liver cancer admitted to Suzhou Ninth People’s Hospital from January 2020 to December 2023 were retrospectively analyzed.Thirty-five patients underwent laparoscopic hepatectomy for liver cancer(liver cancer resection group)and 35 patients underwent medical image-guided microwave ablation(liver cancer ablation group).The short-term efficacy,complications,liver function,and immune function indices before and after treatment were compared between the two groups.RESULTS One month after treatment,19 patients experienced complete remission(CR),8 patients experienced partial remission(PR),6 patients experienced stable disease(SD),and 2 patients experienced disease progression(PD)in the liver cancer resection group.In the liver cancer ablation group,21 patients experienced CR,9 patients experienced PR,3 patients experienced SD,and 2 patients experienced PD.No significant differences in efficacy and complications were detected between the liver cancer ablation and liver cancer resection groups(P>0.05).After treatment,total bilirubin(41.24±7.35 vs 49.18±8.64μmol/L,P<0.001),alanine aminotransferase(30.85±6.23 vs 42.32±7.56 U/L,P<0.001),CD4+(43.95±5.72 vs 35.27±5.56,P<0.001),CD8+(20.38±3.91 vs 22.75±4.62,P<0.001),and CD4+/CD8+(2.16±0.39 vs 1.55±0.32,P<0.001)were significantly different between the liver cancer ablation and liver cancer resection groups.CONCLUSION The short-term efficacy and safety of microwave ablation and laparoscopic surgery for the treatment of liver cancer are similar,but liver function recovers quickly after microwave ablation,and microwave ablation may enhance immune function.

Recent developments in non-invasive methods for assessing metabolic dysfunction-associated fatty liver disease

The prevalence of metabolic dysfunction-associated fatty liver disease(MAFLD)is increasing,affecting over one-third of the global population and contributing to significant morbidity and mortality.Diagnosing MAFLD,especially with advan-ced fibrosis,remains challenging due to the limitations of liver biopsy,the current gold standard.Non-invasive tests are crucial for early detection and management.Among these,the fibrosis-4 index(Fib-4)is widely recommended as a first-line test for screening for liver fibrosis.Advanced imaging techniques,including ultrasound-based elastography and magnetic resonance elastography,offer high accuracy but are limited by cost and availability.Combining biomarkers,such as in the enhanced liver fibrosis score and FibroScan-AST score,enhances diagnostic precision and is recommended to further stratify patients who are considered to be intermediate or high risk from the Fib-4 score.We believe that the future lies in the combined use of biomarkers to improve diagnostic accuracy.

Endoscopic retrograde cholangiopancreatography and liver biopsy in the evaluation of elevated liver function tests after liver transplantation

BACKGROUND Abnormal liver function tests(LFTs)in post-liver transplant(LT)patients pose a challenge in the timing and selection of diagnostic modalities.There are little data regarding the accuracy of endoscopic retrograde cholangiopancreatography(ERCP)and liver biopsy(LB)in diagnosing post-transplant complications.AIM To evaluate the diagnostic performance of ERCP and LB in patients with nonvascular post-LT complications.METHODS This single-center retrospective study evaluated patients undergoing both ERCP and LB for evaluation of elevated LFTs within 6 mo of LT from 2000 to 2017.Diagnostic operating characteristics including accuracy,sensitivity and specificity for various diagnoses were calculated for ERCP and LB.The R factor(ratio of alkaline phosphatase to alanine aminotransferase)was also calculated for each patient.RESULTS Of the 1284 patients who underwent LT,91 patients(74.7%males,mean age of 51)were analyzed.Anastomotic strictures(AS,24.2%),acute cellular rejection(ACR,11%)and concurrent AS/ACR(14.3%)were the most common diagnoses.ERCP carried an accuracy of 79.1%(95%CI:69.3-86.9),LB had an accuracy of 93.4%(95%CI:86.2-97.5),and the combination of the two had an accuracy of 100%(95%CI:96-100).There was no difference between patients with AS and ACR in mean R factor(AS:1.9 vs ACR:1.1,P=0.24).Adverse events did not differ between the two tests(ERCP:3.1%vs LB:1.1%,P=0.31).CONCLUSION In patients with abnormal LFTs after LT without vascular complications,the combination of LB and ERCP carries low risk and improves diagnostic accuracy over either test alone.

Functional Liver Imaging Score Derived from Gadoxetic Acid-enhanced MRI Predicts Cachexia and Prognosis in Hepatocellular Carcinoma Patients

Objective Cachexia occurs in approximately half of hepatocellular carcinoma(HCC)patients as the disease progresses and is correlated with a poor prognosis.Therefore,early identification of HCC patients at risk of developing cachexia and their prognosis is crucial.This study investigated the functional liver imaging score(FLIS)derived from gadoxetic acid-enhanced magnetic resonance imaging(MRI)to identify cachexia in HCC patients and their prognosis.Methods Pretreatment clinical and MRI data from 339 HCC patients who underwent gadoxetic acid-enhanced MRI scans were retrospectively collected.Patient weights were recorded for 6 months following the MRI scan to diagnose cachexia.The FLIS was calculated as the sum of the enhancement quality score,the excretion quality score,and the portal vein sign quality score.A Cox proportional hazards model was used to determine the significant factors affecting overall survival(OS).Multivariable logistic regression was then conducted to identify variables predicting cachexia in HCC patients,which were subsequently used to predict OS.Results Cox regression analysis revealed a significant association between cachexia and worse OS.Both FLIS(0–4 vs.5–6 points)(OR,9.20;95%CI:4.68–18.10;P<0.001)andα-fetoprotein>100 ng/mL(OR,4.08;95%CI:2.13–7.83;P<0.001)emerged as significant predictors of cachexia in patients with HCC.Furthermore,FLIS(0–4 vs.5–6 points)(HR,1.73;95%CI:1.19–2.51;P=0.004)was significantly associated with OS.Patients in the FLIS 0–4 points group had shorter OS than those in the FLIS 5–6 points group[20 months(95%CI,14.7–25.3)vs.43 months(95%CI,27.7–58.3);P=0.001].Conclusion Cachexia was associated with worse OS.The functional liver imaging score emerged as a significant predictor of cachexia in HCC patients and their prognosis.

Prevalence and risk factors for impaired renal function among Asian patients with nonalcoholic fatty liver disease

Background:Nonalcoholic fatty liver disease(NAFLD)is associated with impaired renal function,and both diseases often occur alongside other metabolic disorders.However,the prevalence and risk factors for impaired renal function in patients with NAFLD remain unclear.The objective of this study was to identify the prevalence and risk factors for renal impairment in NAFLD patients.Methods:All adults aged 18-70 years with ultrasound-diagnosed NAFLD and transient elastography examination from eight Asian centers were enrolled in this prospective study.Liver fibrosis and cirrhosis were assessed by FibroScan-aspartate aminotransferase(FAST),Agile 3+and Agile 4 scores.Impaired renal function and chronic kidney disease(CKD)were defined by an estimated glomerular filtration rate(eGFR)with value of<90 mL/min/1.73 m^(2) and<60 mL/min/1.73 m^(2),respectively,as estimated by the CKD-Epidemiology Collaboration(CKD-EPI)equation.Results:Among 529 included NAFLD patients,the prevalence rates of impaired renal function and CKD were 37.4%and 4.9%,respectively.In multivariate analysis,a moderate-high risk of advanced liver fibrosis and cirrhosis according to Agile 3+and Agile 4 scores were independent risk factors for CKD(P<0.05).Furthermore,increased fasting plasma glucose(FPG)and blood pressure were significantly associated with impaired renal function after controlling for the other components of metabolic syndrome(P<0.05).Compared with patients with normoglycemia,those with prediabetes[FPG≥5.6 mmol/L or hemoglobin A1c(HbA1c)≥5.7%]were more likely to have impaired renal function(P<0.05).Conclusions:Agile 3+and Agile 4 are reliable for identifying NAFLD patients with high risk of CKD.Early glycemic control in the prediabetic stage might have a potential renoprotective role in these patients.

Interplay between metabolic dysfunction-associated fatty liver disease and renal function: An intriguing pediatric perspective

Over recent years,the nomenclature of non-alcoholic fatty liver disease has undergone significant changes.Indeed,in 2020,an expert consensus panel proposed the term“Metabolic(dysfunction)associated fatty liver disease”(MAFLD)to underscore the close association of fatty liver with metabolic abnormalities,thereby highlighting the cardiometabolic risks(such as metabolic syndrome,type 2 diabetes,insulin resistance,and cardiovascular disease)faced by these patients since childhood.More recently,this term has been further replaced with metabolic associated steatotic liver disease.It is worth noting that emerging evidence not only supports a close and independent association of MAFLD with chronic kidney disease in adults but also indicates its interplay with metabolic impairments.However,comparable pediatric data remain limited.Given the progressive and chronic nature of both diseases and their prognostic cardiometabolic implications,this editorial aims to provide a pediatric perspective on the intriguing relationship between MAFLD and renal function in childhood.

Clinical effect of spleen aminopeptide on improving liver function damage and immune function in children with infant hepatitis syndrome

BACKGROUND Infant hepatitis syndrome(IHS)is a clinical syndrome in infants less than one year of age with generalized skin jaundice,abnormal liver function,and hepato-megaly due to various etiologies such as infection.AIM To investigate the effect of IHS patients,after treatment with arsphenamine-based peptides,on patients'liver function damage and immune function.METHODS Of 110 patients with IHS treated in our hospital from January 2019 to January 2021 were grouped according to the randomized residual grouping method,with 5 cases in each group shed due to transfer,etc.Ultimately,50 cases remained in each group.The control group was treated with reduced glutathione,and the treat-ment group was treated with sesquiterpene peptide based on the control group.Observe and compare the differences in indicators after treatment.RESULTS The comparison of serum total bilirubin,direct bilirubin,and serum alanine transferase after treatment was significantly different and lower in the treatment group than in the control group(P<0.05).The comparison of CD4+,CD3+,CD4+/CD8+after treatment was significantly different and higher in the treatment group than in the control group,and the comparison was statist-ically significant(P<0.05).The complication of the two groups showed that the rash,cough and sputum,elevated platelets,and gastrointestinal reactions in the treatment group were significantly lower than those in the control group,and the differences were statistically significant by test(P<0.05).CONCLUSION The comparative study of IHS treated with arsphenamine combined with reduced glutathione is more effective.

Effects of Lactobacillus paracasei N1115 on gut microbial imbalance and liver function in patients with hepatitis B-related cirrhosis

BACKGROUND Hepatitis B cirrhosis(HBC)is a chronic disease characterized by irreversible diffuse liver damage and aggravated by intestinal microbial imbalance and metabolic dysfunction.Although the relationship between certain single probiotics and HBC has been explored,the impact of the complex ready-to-eat Lactobacillus paracasei N1115(LP N1115)supplement on patients with HBC has not been determined.AIM To compare the changes in the microbiota,inflammatory factor levels,and liver function before and after probiotic treatment in HBC patients.METHODS This study included 160 HBC patients diagnosed at the General Hospital of Ningxia Medical University between October 2018 and December 2020.Patients were randomly divided into an intervention group that received LP N1115 supplementation and routine treatment and a control group that received routine treatment only.Fecal samples were collected at the onset and conclusion of the 12-wk intervention period.The structure of the intestinal microbiota and the levels of serological indicators,such as liver function and inflammatory factors,were assessed.RESULTS Following LP N1115 intervention,the intestinal microbial diversity significantly increased in the intervention group(P<0.05),and the structure of the intestinal microbiota was characterized by an increase in the proportions of probiotic microbes and a reduction in harmful bacteria.Additionally,the intervention group demonstrated notable improvements in liver function indices and significantly lower levels of inflammatory factors(P<0.05).CONCLUSION LP N1115 is a promising treatment for ameliorating intestinal microbial imbalance in HBC patients by modulating the structure of the intestinal microbiota,improving liver function,and reducing inflammatory factor levels.

Cortical activity in patients with high-functioning ischemic stroke during the Purdue Pegboard Test:insights into bimanual coordinated fine motor skills with functional near-infrared spectroscopy

After stroke,even high-functioning individuals may experience compromised bimanual coordination and fine motor dexterity,leading to reduced functional independence.Bilateral arm training has been proposed as a promising intervention to address these deficits.However,the neural basis of the impairment of functional fine motor skills and their relationship to bimanual coordination performance in stroke patients remains unclear,limiting the development of more targeted interventions.To address this gap,our study employed functional near-infrared spectroscopy to investigate cortical responses in patients after stroke as they perform functional tasks that engage fine motor control and coordination.Twenty-four high-functioning patients with ischemic stroke(7 women,17 men;mean age 64.75±10.84 years)participated in this cross-sectional observational study and completed four subtasks from the Purdue Pegboard Test,which measures unimanual and bimanual finger and hand dexterity.We found significant bilateral activation of the sensorimotor cortices during all Purdue Pegboard Test subtasks,with bimanual tasks inducing higher cortical activation than the assembly subtask.Importantly,patients with better bimanual coordination exhibited lower cortical activation during the other three Purdue Pegboard Test subtasks.Notably,the observed neural response patterns varied depending on the specific subtask.In the unaffected hand task,the differences were primarily observed in the ipsilesional hemisphere.In contrast,the bilateral sensorimotor cortices and the contralesional hemisphere played a more prominent role in the bimanual task and assembly task,respectively.While significant correlations were found between cortical activation and unimanual tasks,no significant correlations were observed with bimanual tasks.This study provides insights into the neural basis of bimanual coordination and fine motor skills in high-functioning patients after stroke,highlighting task-dependent neural responses.The findings also suggest that patients who exhibit better bimanual performance demonstrate more efficient cortical activation.Therefore,incorporating bilateral arm training in post-stroke rehabilitation is important for better outcomes.The combination of functional near-infrared spectroscopy with functional motor paradigms is valuable for assessing skills and developing targeted interventions in stroke rehabilitation.
