Autoimmune hepatitis is a chronic liver disease putatively caused by loss of tolerance to hepatocyte-specific autoantigens. It is characterized by female predilection, elevated aminotransferase levels, autoantibodies, increased γ-globulin or IgG levels and biopsy evidence of interface hepatitis. It is currently divided into types 1 and 2, based on expression of autoantibodies. Autoantigenic epitopes have been identified only for the less frequent type 2. Although autoimmune hepatitis occurs in childhood, this review focuses on disease in adults. In the absence of pathognomonic biomarkers, diagnosis requires consideration of clinical, biochemical, serological and histological features, which have been codified into validated diagnostic scoring systems. Since many features also occur in other chronic liver diseases, these scoring systems aid evaluation of the differential diagnosis. New practice guidelines have redefined criteria for remission to include complete biochemical and histological normalization on immunosuppressive therapy. Immunosuppression is most often successful using prednisone or prednisolone and azathioprine; however, the combination of budesonide and azathioprine for non-cirrhotic patients offers distinct advantages. Patients failing standard immunosuppression are candidates for alternative immunosuppressive regimens, yet none of the options has been studied in a randomized, controlled trial. Overlap syndromes with either primary sclerosing cholangitis or primary biliary cirrhosis occur in a minority. Liver transplantation represents a life-saving option for patients presenting with acute liver failure, severely decompensated cirrhosis or hepatocellular carcinoma. Transplant recipients are at risk for recurrent autoimmune hepatitis in the allograft, and de novo disease may occur in patients transplanted for other indications. Patients transplanted for AIH are also at risk for recurrent or de novo inflammatory bowel disease. Progress in our understanding of the immunopathogenesis should lead to identification of specific diagnostic and prognostic biomarkers and new therapeutic strategies.

Herbal medicines have recently been recognized as the second most common cause of drug-induced liver injury (DILI) in the United States. However, reliable methods to identify the DILI causality of some herbs, such as Heshouwu (dried root of Polygonum multiflorum), remain lacking. In this study, a total of 12 307 inpatients with liver dysfunction and 147 literature-reported cases of Heshouwu DILI were screened. A general algorithm indicated that only 22.5% (9/40) and 30.6% (45/147) of all hospitalization and literature case reports, respectively, demonstrate the high probability of DILI causality of Heshouwu. By contrast, 95% (19/20) of all cases prospectively investigated by pharmacognosy, phytochemistry, and metabolomic tests exhibited highly probable causality, including a patient who was previously incorrectly attributed and a case that was excluded from Heshouwu causality by pharmacognostic evidence. Toxin (heavy metals, pesticides, and mycotoxins) contamination was also excluded from Heshouwu DILI causality. The objectivity of these screening methods for Heshouwu DILI diagnosis addresses safety concerns regarding stilbene-containing herbal medicines and dietary supplements.

The present study was designed to investigate the protective effects of leonurine, a compound purified from that is active on ischemic rat behavior and cortical neurons, and explore the underlying mechanism. The general rat activity, cortical neuron morphology, superoxide dismutase (SOD), malondialdehyde (MDA), -aminobutyric acid (GABA) and glutamate decarboxylase 67 (GAD67) levels were measured. We found leonurine significantly improve the general activity of rats in an open-field test, which was associated with attenuated neuronal damage induced by ischemia. Moreover, serum SOD activity was significantly greater, MDA level lower in the leonurine group as compared with ischemia group. In addition, GABA content in the cerebral cortex was significantly greater in high-dose leonurine group. Correspondingly, GAD67 protein level coincided with the GABA level. Taken together, our results demonstrated that leonurine attenuated brain injury during ischemia via antioxidative and anti-excitotoxicity effects by targeting GABA and leonurine might become a useful adjuvant neuroprotective agent.

Glucagon-like peptide-2 (GLP-2) has potent anti-inflammatory effects and protects against experimental ischemia/reperfusion (I/R) injury in pulmonary, intestinal, and myocardial tissue. However, its protective abilities against I/R injury in the liver are unknown. We investigated the potential role of GLP-2 pretreatment on hepatic I/R injury in rats. A total of 24 rats were randomly divided into three groups (n = 8). The first group was the control group; the second group was the vehicle-treated hepatic ischemia/reperfusion (HIR, vehicle saline-treated) group; and the third group was the GLP-2 pretreated I/R (GLP2-IR) group. Each rat in the third group was intraperitoneally administered 5 μg GLP-2 for 5 d before the procedure. A portal triad was created to induce ischemia with a vascular atraumatic clamp. After 40 min, the clamp was released to initiate hepatic reperfusion for 6 h. Blood samples and tissue specimens from the liver were obtained. Alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels significantly increased in the saline-treated HIR group (P<0.001), whereas GLP-2 pretreatment significantly decreased their levels (P<0.01). Our data suggested that GLP-2 pretreatment may have a protective effect on liver I/R injury. However, dose-response studies are necessary to determine the most effective dose.

准确评估和追踪特异性肝损伤及其进程仍然是当前生物标志物研究中的一大挑战。本研究建立了一种回顾追溯验证方法,用以表征α-萘异硫氰酸酯(ANIT)诱导的特异性肝脏胆管损伤后血清标志物与组织标志物之间的互动关系。研究发现羧酸酯酶1(CES1)作为肝内标志物和二肽基肽酶4(DPP-IV)作为肝外标志物可反映肝脏损伤的不同病理生理状态。CES1 和DPP-IV 水平可甄别肝损伤本身和炎症损伤之间的差异。相比之下,常规血清学标志物碱性磷酸酶(ALP)、丙氨酸转氨酶(ALT)和天冬氨酸转氨酶(AST)在ANIT诱导损伤后血清和组织水平同时升高,胆汁中胆汁酸水平下降,血清中胆汁酸水平升高,肝内组织中胆汁酸水平升高。尽管血清与组织中γ-谷氨酰基转肽酶(γ-GT)升降水平的变化方向相反,但其持续时间远短于CES1,并迅速恢复到正常水平。在上述生物标志物中,只有CES1 能够明确排除炎症干扰下的肝细胞损伤。CES1 还能准确评估熊去氧胆酸(UDCA;单成分药物)和清肺排毒汤(QFPDD;多组分药物)的抗胆汁淤积作用。研究发现QFPDD和UDCA均能减轻ANIT 诱导的肝损伤。UDCA在促进胆汁排泄方面的效果更强,但其抗损伤和抗炎作用相对较弱,而QFPDD在阻断肝脏炎症和修复肝损伤方面更有效。本文数据强调了联合使用CES1(作为肝内肝损伤标志物)和DPP-IV(作为肝外炎症作用标志物)可准确评估和追踪特异性肝损伤,并可区分肝损伤和炎症性肝损伤的差异。

Bile duct injury is a common complication of cholecystectomy. The timing of bile duct injury repair remains controversial. A recent review conducted in France reported 39% complications and 64% failure after immediate repair in 194 patients compared with 14% complications and 8% failure after late repair in 133 patients. A national review of 139 consecutive early repairs conducted at five hepatopancreaticobiliary centers in Denmark reported 4% mortality, 36% morbidity, and 42 restrictures (30%) at a median follow-up of 102 months, and only 64 patients (46%) demonstrated uneventful short-term and long-term outcomes. Most patients with bile duct injury present with bile leak and sepsis; thus, early repair is not recommended. Percutaneous drainage of bile and endoscopic stenting are the mainstays of treatment of bile leak because they convert acute bile duct injury into a controlled external biliary fistula. The ensuing benign biliary stricture should be repaired by a biliary surgeon after a delay of 4–6 weeks once the external biliary fistula has closed.

Partial liver transplantation, including reduced-size liver transplantation, split liver transplantation, and living donor liver transplantation, has been developed with several innovative techniques because of donor shortage. Reduced-size liver transplantation is based on Couinaud’s anatomical classification, benefiting children and small adult recipients but failing to relieve the overall donor shortage. Split liver transplantation provides chances to two or even more recipients when only one liver graft is available. The splitting technique must follow stricter anatomical and physiological criteria either ex situ or in situto ensure long-term quality. The first and most important issue involving living donor liver transplantation is donor safety. Before surgery, a series of donor evaluations—including anatomical, liver volume, and liver function evaluations—is indispensable, followed by ethnic agreement. At different recipient conditions, auxiliary liver transplantation and auxiliary partial orthotopic liver transplantation, which employ piggyback techniques, are good alternatives. Partial liver transplantation enriches the practice and knowledge of the transplant society.
