Objective The incidence rate of nonalcoholic fatty liver disease (NAFLD) is increasing. It might progress to the end-stage liver disease. However, there is still no specific treatment for this entity. Therefore, the establishment of representative animal models reflecting disease characteristics has become especially important. Although there are many different disease models, there is still a lack of NAFLD model which could cover the whole spectrum of this entity in human. In this paper, we reviewed the current progress on NAFLD model, focusing on animal model, 2D cell model, 3D liver model and their advantages and disadvantages.

Objective Liver is an important organ for the metabolism of sex hormones, lipids and other substances. Male patients with chronic liver disease often suffer from a variety of dysfunctions, such as sex hormone metabolism, glucose and lipid metabolism and mental and psychological disorder. Erectile dysfunction is easy to occur, which affects the physical and mental health and the family life of patients.Existing studies have shown that the prevalence of male erectile dysfunction in patients with chronic liver disease was 24.6% to 85%, the prevalence in chronic hepatitis patients was 8.6% to 78%, and in patients with cirrhosis was 41.2% to 92%.In this paper, we reviewed the incidence, impacting factors, possible pathogenesis, and treatment of erectile dysfunctions in male patients with chronic liver disease.

Objective The aim of this study was to summarize manifestations of hepatic hemangioma (HH) by using grayscale ultrasound, color Doppler flow imaging (CDFI) and contrast-enhanced ultrasound (CEUS), in order to help clinicians making diagnosis. Methods 62 patients with HH were encountered in Jingmen People's Hospital, affiliated to Jingchu Institute of Technology between January 2022 and August 2024, all patients underwent grayscale ultrasound, CDFI and CEUS examination, and underwent surgical resection. Results Tumor resection completed successfully in all the 62 patients with HH in our series, and histopathological examination diagnosed cavernous hemangioma in 44 cases, sclerosing hemangioma in 7 cases, vascular endothelial cell tumor in 6 cases and capillary hemangioma in 5 cases; ultrasonography showed that the size of HH lesions in this group ranged from 1.5 to 84 cm, with an average of (4.6 ± 1.3) cm, and the lesions presented irregular edges and non-spherical shapes; the lesion presented as enhanced echo or uneven echo distribution; CDFI examination demonstrated the lesions presented as spotted short columnar blood flow signals, with blood flow phenomena found within and around the vascular tumor; CEUS examination showed a slightly hyperechoic nodule in the liver, which appeared as a nodular ring-shaped high-intensity enhancement at arterial phase, subsequently, the contrast agent cleared or manifested as a slightly hyperechoic nodule in the liver; at portal and delayed phases, the contrast agent gradually filled the center, showing high-intensity enhancement. Conclusions The HH is relatively easy to diagnose by gray scale and color Doppler ultrasonography, and for some lesions that are difficult to determine, CEUS examination might be used to help further clarify the diagnosis.

Objective Dietary copper restriction has long been considered an important treatment for patients with hepatolenticular degeneration (HLD). However, evidence supporting this approach is limited. There are no published randomised controlled trials for the recommendation due to rarity of the disease and variable presentation. This review summarized current knowledge on the absorption and regulation of copper in humans and its relevance to patients with HLD. Studies have demonstrated that as the level of dietary copper increases, the proportion absorbed decreases. This observation implies that ‘high copper' foods that HLD patients are generally advised to avoid would need to be consumed in large amounts to impact markedly on the quantity absorbed. Dietary copper restriction is unlikely to reduce the amount absorbed significantly and is not only difficult to manage but restricts food supply unnecessarily, detracting from the provision of substrates essential for improving nutritional status in a nutritionally compromised group. Medical management for HLD is effective in compliant patients, allowing stabilization of the liver disease. Based on current evidence, dietary copper restrictions in stable HLD patients who are adherent to medical therapy are unnecessary with two food exceptions (shellfish and liver organ).

Objective Liver fibrosis is caused by excessive deposition of extracellular matrix in liver tissues due to repeated liver injuries and hypoxia injury is a part of liver injury. Hypoxia inducible factor-1 α (HIF-1α) is a key transcription factor in response to hypoxia stress, and its expression in liver fibrotic tissues and activated HSCs is significantly increased. At present, a number of HIF-1α dependent genes and related signaling pathways have been studied to confirm that the changes of these genes and pathways are related to the development of liver fibrosis, suggesting that HIF-1α may play a key role in liver fibrosis. In this review, the mechanism of HIF-1α-related signaling pathway in the development of liver fibrosis and the synthesis and degradation of HIF-1α from the upstream are described.

The accuracy of bile CT value is relatively higher in the diagnosis of gallbladder muddy stones.

Objective Bile acid(BA) is synthesized in the liver and is the major component of bile. BAs accumulates in serum and liver when BAs secretion is impaired, which is followed by liver injury. The molecular mechanism of cholestasis has been extensively studied, however, it remains controversial. Recent studies showed that BAs might induce hepatocyte injury under pathological conditions, and the mechanism involved inflammatory response induced by stressed hepatocytes. In this article, we reviewed recent advances in the pathogenesis of liver injury induced by BAs and we focused on how BAs induce the activation of inflammatory cytokines that further induce the aggregation of immune cells. Based on these pathogenesis, we tentatively point out a number of novel treatments for cholestatic liver damage.

The nonalcoholic fatty liver disease (NAFLD) is considered to be the metabolic disorders in liver and is closely related to obesity, insulin resistance (IR), type 2 diabetes mellitus (T2DM) and hyperlipemia, etc. The prevalence of NAFLD among adults worldwide is about 25% and it is to believe increasing year by year. The NAFLD is an important causes of liver cirrhosis, liver cancer and liver transplantation. A large number of studies have shown that thyroid hormone (THs) plays an important role in hepatic lipid metabolism and IR, and the thyroid hormone receptor agonists are expected to become new medicines for the treatment of patients with NAFLD. In this review, we mainly discuss the progress of THs in patients with NAFLD.

Objective To estimate the effectiveness and safety of magnesium isoglycyrrhizinate injection （MIG） for the treatment of patients with cirrhosis. Methods All the randomized controlled trials（RCT） about the effectiveness and safety of MIG for the treatment of patients with cirrhosis were collected by searching databases including Pubmed，Embse，Cochrane library，CBM，Wanfang，CNKI and VIP. The screening of literatures，extraction of information and evaluation of the risk of bias were accomplished by two independent reviewers. Statistical analyses were performed with RevMan 5.2 software. Results A total of 9 RCTs involving 576 patients were included，while the methodology of the included studies was of low quality. The meta-analysis showed that the clinical effective rate of MIG used alone or in combination with other liver-protecting agents was significantly higher than in other hepatoprotective drugs （RR: 1.23，95%CI: 1.07 to 1.42，P<0.01） and （RR:1.31，95%CI: 1.13 to 1.51，P<0.01） with remarkably improved liver function and no severe side effects. Conclusion MIG injection is superior to other hepatoprotective drugs for liver cirrhosis with fewer side effects. However，more controlled trials of high quality are required to further assess the effectiveness and safety of MIG for patients with cirrhosis.

Objective To compare the value of contrast-enhanced CT and contrast-enhanced ultrasonography in the diagnosis of patients with focal liver lesions. Methods 81 patients with focal liver lesions were recruited in our hospital between March 2012 and May 2015. All the patients underwent contrast-enhanced CT check-up and contrast-enhanced ultrasonography. The imaging characteristics and the imaging parameters of ultrasonic contrast of benign and malignant liver lesions were recorded. Then，a comparison of the diagnostic efficacy of the two Methods was conducted. Results This study included 41 patients with hepatocellular carcinoma（HCC） and 40 with benign liver lesions. The quantitative analysis of the Results of contrast-enhanced ultrasonography revealed that time to peak，rise time and mean transit time in patients with malignant liver lesions were significantly shorter than those in patients with benign lesions [（33.2±5.8） s vs. （48.6±13.2） s，（24.1±4.9） s vs. （38.7±11.5） s，（108.5±21.3） s vs. （156.7±35.6） s，respectively，P<0.05 for all]，while the perfusion index in patients with malignant liver lesions was significantly higher than that in patients with benign lesions[（145.3±39.2） vs.（83.6±17.9），P<0.05]；The sensitivity，specificity，and accuracy of the contrast-enhanced ultrasonography were 97.1%， 92.3% and 96.3%，while those of contrast-enhanced CT were 80.3%（P<0.05），91.2%（P>0.05）and 85.2%（P<0.05）. Conclusion Contrast-enhanced ultrasonography could provide abundant imaging information of hepatic lesions in terms of morphology and data measurement，with high sensitivity and diagnostic accuracy in diagnosis of patients with liver lesions.

Objective To summarize the diagnostic value of two diagnostic criteria in diagnosis of patients with drug-induced liver injury（DILI） in Chinese population. Methods We searched publications about Chinese patients in journal full-text database,Wanfang database and pubmed database with keywords of drug-induced liver injury,diagnostic criteria,diagnostic scoring system,RUCAM and Maria scale. Literature review,case reports,and duplication data were excluded. Age,gender and diagnostic criteria were summarized. Results A total of 7 papers including 1352 patients with DILI were included in this analysis. The age range of the patients in this series was 2 to 91 years old. Six papers having 997 cases （97.1%） were diagnosed as DILI,and 30 cases （2.9%） were not diagnosed as DILI by RUCAM scale. Four papers having 736 cases（58.8%） were diagnosed as DILI,and 303 cases（41.2%） were not diagnosed as DILI by Maria scale. Conclusion The diagnostic results of DILI by RUCAM scale and Maria scale were not the same sometimes,which warrants further study.

Primary biliary cholangitis (PBC), also known as primary biliary cirrhosis, is a chronic intrahepatic autoimmune cholestatic disease. Ursodeoxycholic acid (UDCA) is first line of treatment for PBC, which can improve biochemical indicators and slow down disease progress, while 30% to 40% of patients with PBC still have poor response to UDCA therapy, which is called refractory PBC. These patients have a higher incidence of cirrhosis and related complications, and early warning, institution treatment and prognosis evaluation for these patients remain a major challenge. The aim of this review is to present the latest research on the clinical features, influencing factors, therapeutic medicines and prognosis of patients with refractory PBC.
