BACKGROUND: Patients with decompensated hepatitis B vires (HBV)-related cirrhosis tend to have low or undetectable HBV replication. However, some patients continue to have high levels of HBV replication and effective suppression of HBV replication with antiviral agents may potentially decrease hepatic necroinflammation and improve or stabilize liver function. This review was to under stand the efficacy and safety of lamivudine in the treatment of decompensated HBV cirrhosis. DATA SOURCES: An English-language literature search (MEDLINE January 1988-July 2005) was performed, and a total of 52 articles/abstracts relevant to the issue were selected. After review of the selected papers, the meaningful results and conclusions were extracted using scientific crite ria. The papers reviewed pertained mainly to the efficacy and safety profiles of lamivudine treatment for decompensated HBV cirrhosis. RESULTS: The ultimate treatment of decompensated HBV cirrhosis is liver transplantation, but lamivudine treatment may lead to rapid suppression of viral replication and improvement of biochemical and clinical parameters, reduced morbidity and hospitalization for complications of liver disease, increased pre-transplant survival as well as reduced need for transplantation. However, viral resistance can develop after prolonged treatment with lamivudine, and breakthrough hepatitis may be fatal in few patients. Adefovir is effective for lamivudine-resistant HBV mutants. CONCLUSIONS: Antiviral therapy with lamivudine for decompensated HBV cirrhosis can be effective. However, some patients may experience a hepatitis flare with the emergence of YMDD mutants resulting in progressive worsening of liver disease, and should be referred for 'rescue' therapy with other nucleoside/nucleotide analogues such as adefovir dipivoxil.

AIM： To analyze the clinical and endoscopic features of Chinese patients with reflux esophagitis （RE）. METHODS： A total of 1405 RE patients were analyzed retrospectively. Data on gender, age, presence/absence of H pylori infection and associated esophageal hiatal hernia were collected. Esophagitis was divided into different grades according to Los Angeles Classification. RESULTS： Of 18823 patients, 1405 were diagnosed as RE. The ratio of male to female patients was 1.75：1 （P 〈 0.01）. The mean age of male and female patients was significantly different （P = 0.01）. The peak age at onset of the disease was 40-60 years. According to Los Angeles Classification, there were significant differences in the age of patients with grades A and B compared to patients with grades C and D （P 〈 0.01）. Two hundred and seventy-seven patients were infected with H pyiorl, the infection rate was low （P 〈 0.01）. Complication of esophageal hiatal hernia was found to be significantly associated with the severity of esophagitis and age in 195 patients （P 〈 0.01）. Esophageal mucosa damages were mainly located at the right esophageal wall. CONCLUSION： The peak age of onset of RE is 40-60 years and higher in males than in females. The mean age of onset of RE is lower in males than in females. The infection rate of Hpylori is significantly decreased in patients with esophagitis. Old age and esophageal hiatal hernia are associated with more severe esophagitis. Right esophageal mucosal damage can occur more often in RE patients.

BACKGROUND: Primary biliary cirrhosis (PBC) is cha- racterized by frequent presence of antimitochondrial anti- bodies (AMAs). The sensitivity and specificity of AMA for PBC are both greater than 90%-95%, so the presence of AMA in serum is the major hallmark in PBC. However, it has long been recognized that in 5%-10% of patients the clinical, biochemical and histological features are diagnos- tic for PBC, but their sera are consistently tested negative for AMA/AMA-M2. This study aimed to evaluate whether the presence of AMA alters the clinical, serological and his- tological features of the disease. METHODS: Clinical data of 70 patients clinically and/or histologically diagnosed with PBC were reviewed. AMA- negative and AMA-positive patients were compared in terms of clinical, biochemical, immunological and histo- logical features. RESULTS: At presentation, 11 patients were serum AMA/ AMA-M2 negative. At the initial visit, AMA-negative and AMA-positive patients were similar in terms of age, sex, clinical manifestations, liver biochemistries and histological findings. The mean level of serum immunoglobulin M (IgM) was significantly lower in AMA-negative PBC pa- tients than in AMA-positive PBC patients (2851±1418 mg/L vs 6361 ±4928 mg/L, P =0.033). Serum antinuclear anti- bodies ( ANA) and/or smooth muscle antibodies ( SMA) were more frequently positive in the AMA-negative PBC patients than in the AMA-positive patients (81.8% vs 40.7%, P =0.031). CONCLUSION: AMA-negative PBC patients are characte- rized by relatively lower levels of serum IgM and a higher prevalence of serum ANA/SMA and are not associated with substantial differences in the clinical, biochemical and histo- logical spectrum of the disease.

X-ray phase-contrast imaging (PCI) is a new emerging imaging technique that generates a high spatial resolution and high contrast of biological soft tissues compared to conventional radiography. Herein a biomedical application of diffraction enhanced imaging (DEI) is presented. As one of the PCI methods, DEI derives contrast from many different kinds of sample information, such as the sample’s X-ray absorption, refraction gradient and ultra-small-angle X-ray scattering (USAXS) properties, and the sample information is expressed by three parametric images. Combinedwith computed tomography (CT), DEI-CT can produce 3D volumetric images of the sample and can be used for investigating micro-structures of biomedical samples. Our DEI experiments for liver samples were implemented at the topography station of beijing Synchrotron Radiation Facility (BSRF). The results show that by using our provided information extraction method and DEI-CT reconstruction approach, the obtained parametric images clearly display the inner structures of liver tissues and the morphology of blood vessels. furthermore, the reconstructed 3D view of the liver blood vessels exhibits the micro blood vessels whose minimum diameter is on the order of about tens of microns, much better than its conventional CT reconstruction at a millimeter resolution. In conclusion, both the information extraction method and DEI-CT have the potential for use in biomedical micro-structures analysis.

Ischemic preconditioning (IPC) protects liver graft function following ischemia in liver transplantation and liver resection. The aim of this study was to assess the advantages and any potential disadvantages of liver IPC prior to isolation for rat hepatocytes during isolation and cryopreservation. After isolating and thawing the cryopreserved hepatocytes after 14 and 28 d,cell viability,efficiency,and lactate dehydrogenase (LDH) levels in preserve solution were examined for every group. Groups treated with IPC had better cell viability determination,assessment of plating efficiency and lactate dehydrogenase (LDH) assay than Group without IPC,suggesting that IPC prior to isolation may have a significant protective effect on hepatocytes subjected to isolation and short period cryopreservation.
