Protein-calorie malnutrition is frequently observed in patients with advanced liver cirrhosis. There have been continued interests in potential benefits of long-term oral branched-chain amino acid supplement in improving severity of liver disease. However, there are limited evidences in literature. The aim of this study is to evaluate the efficacy of oral branched-chain amino acid in patients with advanced liver cirrhosis.

Primary biliary cirrhosis (PBC) is a slowly progressive disease that causes substantial loss of intrahepatic bile ducts, ultimately resulting in cholestasis, advanced fibrosis, cirrhosis, liver failure and even hepatocellular carcinoma. Histologically, the disease is characterized by chronic portal inflammation with infiltration, destruction and loss of the epithelial cells in the small-sized and medium-sized bile ducts. Currently, Ursodeoxycholic acid (UDCA) in a dose of 13-15mg/kg/day is recommended as therapeutic drugs for PBC by AASLD and is approved for this indication by the U.S. Food and Drug Administration (FDA). Treatment with UDCA may delay disease progression and prolong survival free of liver transplantation. However, one out of three patients does not adequately respond to UDCA therapy and many need additional medical therapy or liver transplantation, or both. UC-MSC has been application for the treatment of several severe autoimmune diseases, such as immune thrombocytopenia, systemic lupus erythematosus, and therapy-resistant rheumatoid arthritis. In this study, the safety and efficacy of UC-MSC transplantation for PBC patients will be evaluated.

HBV related Liver disease is a common medical problem in China. An estimated 7.18% of the Chinese (about 93 million) is infected with hepatitis B, and most of the HBV- related hepatitis can developed into liver cirrhosis. Liver transplantation is the only available life saving treatment for patients with end stage liver disease. However, lack of donors, surgical complications, rejection, and high cost are serious problems. Mesenchymal stem cells (MSCs) possess plasticity and have the potential to differentiate into hepatocyte; Thus, MSCs hold great hope for therapeutic applications. Human umbilical cord-derived MSCs (hUC-MSCs) exhibit a more beneficial immunogenic profile and greater overall immunosuppressive potential than aged bone marrow-derived MSCs. Like MSCs derived from bone marrow, hUC-MSCs can also be used to treat rat liver fibrosis and improve glucose homeostasis in rats with liver cirrhosis. In this study, the patients with HBV-related liver cirrhosis will undergo administration of hUC-MSCs via hepatic artery to evaluate the safety and efficacy of hUC-MSC treatment for these patients.

Cystic fibrosis (CF) is the most common inherited disease among the Caucasian population with considerable morbidity and reduced life expectancy. Excessive oxidants released by activated inflammatory cells and persisting infections are considered the main mechanism of damage of respiratory epithelium in CF.Glutathione (GSH) represents the first-line defence of the lung against oxidative stress-induced cell injury; however, a depletion of its levels has been observed in the airways of patients affected by CF. In vitro studies have showed that CFTR protein plays a pivotal role in transmembrane glutathione transport. Therapeutic approaches with inhaled GSH could improve the reduced lung antioxidant capacity in order to counterbalance the oxidant stress linked to the chronic airway inflammation and bacterial infection. Primary objective of the study is to investigate whether a 12 months treatment with inhaled GSH can improve airway obstruction in CF patients. Secondary objectives include the effects of GSH therapy on exercise capacity, body mass index (BMI), respiratory symptoms, quality of life, frequency of pulmonary exacerbations, hospital admissions, and antibiotic administration. Moreover the study will evaluate the effect of GSH therapy on markers of oxidative stress in exhaled breath condensate (EBC) and in serum, and on inflammatory markers on brushed nasal epithelial cells.

Orthotopic liver transplantation (OLT) is currently the most effective method for end-stage liver diseases. However, the critical shortage of donor organs, high cost, and the problem of immune rejection limit its clinical application, and even some patients on the waiting list will never survive to receive a matched liver. Stem cell transplantation instead of conventional medical therapy or orthotopic liver transplantation will be a promising alternate approach to regenerate damaged hepatic mass. Adult mesenchymal stem cells (MSCs) are generally thought of as an autologous source of regenerative cells in previous studies.In this study, the safety and efficacy of menstrual blood-derived stem cells transplantation for patients with liver cirrhosis will be evaluated.

Background & Aim: Bone marrow derived mesenchymal stem cells (BM-MSCs) have capacity to differentiate into hepatocytes and anti-fibrotic effect in the experimental model. No study was done in humans with alcoholic liver cirrhosis. The researchers investigated the anti-fibrotic effect of BM-MSCs in alcoholic cirrhosis as Phase II clinical study. Methods: Eleven alcoholic cirrhosis patients (M:F = 10:1) with Child-Pugh's class B and maintenance of alcohol abstinence at least 2 months were enrolled. At baseline, all patients received liver biopsy, hepatic venous pressure gradient (HVPG) measurement and serologic tests. BM-MSCs were isolated from each patient's BM and amplified for one month and injected two times at 4, 8week through Rt. hepatic artery. 5x106cells/mL of BM-MSCs were injected in each session. Follow up biopsy, HVPG and relative expression of tissue transforming growth factor-1 (TGF-β1), α smooth muscle actin (α-SMA) and collagen-1 by real time RT PCR were measured after 12weeks from 2nd BM-MSC injection. The primary outcome was improvement in patients' histology Aim : The researchers aimed to evaluate safety and effectiveness of new therapy with bone marrow derived autologous mesenchymal stem cell for hepatic failure caused by alcoholic liver cirrhosis.

Adult bone marrow is the most common source of SCs for clinical applications.Previous study showed that bone marrow derived stem cells (BMSCs) replace hepatocytes in injured liver, and effectively rescue experimental liver failure and contribute to liver regeneration. In this study, the patients with HBV-related liver cirrhosis will undergo administration of human autologous BMSCs via hepatic artery to evaluate the safty and efficacy of human autologous BMSCs treatment for these patients.

This study is to evaluate the safety and efficacy of umbilical cord blood mononuclear cells transplantation in liver cirrhosis patients.
