Objectives To evaluate the efficacy and safety of h um an hepatocyte transplantation in the treatment of severe hepatitis induced by dr ugs. Methods The primary human hepatocytes were isolated from t he liver of a healthy donor, and they were then cryopreserved. The thawed hepato cytes were transplanted into the patient's spleen via a femoral artery catheter. 2?10~10 hepatocytes were harvested, and 70% of thawed hepatocytes were vi able, and 2?10~9 vital hepatocytes were transplanted. Results One month after the transplantation, clinical symptoms of the recipient were a meliorated obviously, and the levels of BIL, NH3, ALT and AST lowered, while PA elevated. 50 days after discharge from the hospital it was found that biochemica l parameters returned to normal values, and the hepatocyte signal could be detec ted in the spleen with MRI. Conclusion Hepatocyte transplantati on is safe and efficacious.

Objective To identify the LongSAGE tags from yeast LongSAGE library and hyphal LongSAGE library of Candida albicans. Methods The technique called the generation of longer cDNA fragments from serial analysis of gene expression (SAGE) tags was used for gene identification (GLGI). The SAGE tags of 17 bases were converted into their corresponding 3′ cDNA fragments covering hundred bases, and the sequence was analyzed. Results Fifteen out of twenty tags were stably and efficiently extended with the base size between 200-1 000 bp. The sequence was considered to represent a known gene since it matched a full-length transcript sequence with over 95% similarity in the same orientation, including the same 17-bp SAGE tag sequence. Conclusion By using novel SAGE tags as primer, we can identify efficiently many novel transcripts. A combined application of SAGE-GLGI can be used to define the boundary of expressed genes in the genomic sequences in Candida albicans and in other eukaryotic genomes.

Objective To investigate the effects and safety of human hepatocytes transplantation in vivo for the treatment of liver failure. Methods The primary human hepatocytes were collected from normal liver tissue donated by healthy volunteers and preserved by cryopreservation technique. After thawing, the hepatocytes were transplanted into the spleen of patients with severe hepatitis through catheterization of the femoral artery. Then the changes in clinical symptoms, serum biochemical indexes and MRI signals of the spleen were observed in the patients. Results A total of 2?10 10 hepatocytes were isolated from normal liver tissue of healthy volunteers and 75% of the hepatocytes were alive after cryopreservation and thawing. The number of transplanted hepatocytes was 2?109. In the recipients, the clinical symptoms were markedly improved, serum levels of bilirubin, NH_3, ALT and AST were significantly reduced, but that of PTA remarkably increased, after hepatocyte transplantation. The follow-up examination was performed 80d and 270d after discharge from the hospital, and it was showed that all the serum biochemical indexes returned to normal and signals of the hepatocytes were found in the spleen. Conclusions Hepatocyte transplantation is a safe and effective therapy for severe hepatitis. The transplanted hepatocytes can proliferate and differentiate in the spleen to replace or partially compensate the liver function of synthesis, detoxication and metabolism. Contrast enhanced MRI can be a new method for follow-up study of transplanted hepatocytes.

Kidney deficiency is the core of the currence of multiple sclerosis.Invigorating the kidney is the core in treatment of multiple sclerosis,though there are some other commonly used methods,such as dissipating phlegm,promoting blood flow,clearing heat,dispelling dampness and diuresis in aspects of eliminating pathogen,and invigorating spleen for benefiting qi,dispersing stagnated liver-qi,calming mind for tranquillizing in aspects of regulating the function of organs.Either invigorating the kidney is used through the whole course of disease or used at the later stage,it plays an important role in treatment of multiple sclerosis.
