Spontaneous regression of hepatocellular carcinoma is extremely rare, and the exact pathogenesis leading to this remarkable phenomenon remains unclear. We describe a case of spontaneous regression of an incidentally discovered hepatocellular carcinoma in a 63-year-old man with hepatitis C cirrhosis. The regression followed a series of events, in particular, an upper gastrointestinal haemorrhage. Ischaemic insult may be a major pathway leading to tumour regression. As limited data is available in the literature, knowledge and recognition of this rare event will have implications for patient management and may alter treatment. Further, data may be useful to assess if these patients have an altered prognosis with improved survival.

To raise traditional medicine to a higher level of scientific research, a mathematical model has been proposed using symbolic notations and operators to describe several disease symptoms generally recognized in traditional medicine. Even though this model to a certain degree offers a mathematical approach to identify the relationships between yin-yang and the five viscera, it is not an efficient means of explaining the pathology in traditional medicine due to its use of superfluous notations and definitions. In this paper, we introduce two concise operators, a self-development operator and an action operator: the former describes the effect of a viscus in the unbalanced state on other viscera: the latter explains the engendering and restraining relationships between the two viscera. These tools are useful to elucidate the interactions among the states of the five viscera based on yin-yang and the five elements theory. Our mathematical model with these two operators facilitates description for the scheme of deficiency-excess of yin-yang in the five viscera. Accordingly, we have mathematically refined the existing results and shown clinical applications as well.

OBJECTIVESTo study the effectiveness of the lidocaine test in evaluating the liver reserve of rats with experimental liver injury in different phases.
METHODS40 healthy male Wistar rats were divided randomly into experimental and control groups. Rats of the experimental group received subcutaneous CCl4 in oil injection, and rats of the control group received saline injections. Monoethylglycinexylidide (MEGX) test, common hepatic function tests and histological examination of the livers were performed on all the rats.
RESULTSWith the development of the severity in liver injury, the concentrations of the serum MEGX in lidocaine test decreased gradually, which were consistent with liver histological changes. However, the results from the common liver function tests were all abnormal in the experimental group and were not consistent with the liver histological changes.
CONCLUSIONThe results obtained from the MEGX test are more agreeable to liver histological changes than those from common liver function tests. The results from the MEGX test can represent liver histological changes concisely.

8."Small-for-size Graft" and "Small-for-size Syndrome" in Living Donor Liver Transplantation.

Yonsei Medical Journal 2004;45(6):1089-1094
The indications for living donor liver transplantation (LDLT) were successfully expanded from pediatric to adult cases last 15 years. During this process, graft type has been shifted from left side liver to right side liver. Although the introduction of right lobe graft can successfully increase the actual graft size in LDLT, problem related to "small-for-size grafts" have gradually come to light. "Small-for-size syndrome", such as poor bile production, delayed synthetic function, prolonged cholestasis, and intractable ascites, leading to septic complications and higher mortality, are neither specific nor inevitable in low-weight liver grafts. Many factors other than actual graft weight contribute to the occurrence of "small-for-size syndrome". In the clinical setting, surgical modification targeting portal hemodynamics and tissue congestion is a key to overcome "small-for-size syndrome". Until now, several therapeutic options were reported, but further elucidation of the pathogenesis in "small-for-size syndrome" will be a solution for improving the outcomes in adult-to-adult LDLT.

9.The lymphatic vascular system in liver diseases: its role in ascites formation.
Clinical and Molecular Hepatology 2013;19(2):99-104
The lymphatic system is part of the circulatory system and plays a key role in normal vascular function. Its failure plays a crucial role in the development and maintenance of various diseases including liver diseases. Lymphangiogenesis (the growth of lymphatic vessels) and changes in the properties of lymphatic vessels are associated with pathogenesis of tumor metastases, ascites formation, liver fibrosis/cirrhosis and portal hypertension. Despite its significant role in liver diseases and its importance as a potential therapeutic target for those diseases, the lymphatic vascular system of the liver is poorly understood. Therefore, how the lymphatic vascular system in general and lymphangiogenesis in particular are mechanistically related to the pathogenesis and maintenance of liver diseases are largely unknown. This article summarizes: 1) the lymphatic vascular system; 2) its role in liver tumors, liver fibrosis/cirrhosis and portal hypertension; and 3) its role in ascites formation.

BACKGROUNDAcute-on-chronic hepatitis B liver failure (ACLF-HBV) is a clinically severe disease associated with major life-threatening complications including hepatic encephalopathy and hepatorenal syndrome. The aim of this study was to evaluate the short-term prognostic predictability of the model for end-stage liver disease (MELD), MELD-based indices, and their dynamic changes in patients with ACLF-HBV, and to establish a new model for predicting the prognosis of ACLF-HBV.
METHODSA total of 172 patients with ACLF-HBV who stayed in the hospital for more than 2 weeks were retrospectively recruited. The predictive accuracy of MELD, MELD-based indices, and their dynamic change (D) were compared using the area under the receiver operating characteristic curve method. The associations between mortality and patient characteristics were studied by univariate and multivariate analyses.
RESULTSThe 3-month mortality was 43.6%. The largest concordance (c) statistic predicting 3-month mortality was the MELD score at the end of 2 weeks of admission (0.8), followed by the MELD: sodium ratio (MESO) (0.796) and integrated MELD (iMELD) (0.758) scores, DMELD (0.752), DMESO (0.729), and MELD plus sodium (MELD-Na) (0.728) scores. In multivariate Logistic regression analysis, the independent factors predicting prognosis were hepatic encephalopathy (OR = 3.466), serum creatinine, international normalized ratio (INR), and total bilirubin at the end of 2 weeks of admission (OR = 10.302, 6.063, 5.208, respectively), and cholinesterase on admission (OR = 0.255). This regression model had a greater prognostic value (c = 0.85, 95%CI 0.791 - 0.909) compared to the MELD score at the end of 2 weeks of admission (Z = 4.9851, P = 0.0256).
CONCLUSIONSMELD score at the end of 2 weeks of admission is a useful predictor for 3-month mortality in ACLF-HBV patients. Hepatic encephalopathy, serum creatinine, international normalized ratio, and total bilirubin at the end of 2 weeks of admission and cholinesterase on admission are independent predictors of 3-month mortality.
