Serum anti-uveal autoantigen with coiled coil domains and ankyrin repeats (UACA) antibody titer was measured using ELISA in 32 patients with thyroid-associated ophthalmopathy ( TAO ) and 20 patients with Graves' disease (GD) without ophthalmopathy.The level of anti-UACA antibody in TAO group was higher than that in GD group [ (225.91 ± 144.21 vs 187.42 ± 46.77 ) pg/ml,P＜0.05 ],and especially higher in patients with ocular myopathy [ (254.35 ± 168.29 ) pg/ml ].It seems that anti-UACA antibody is the sensitive clinical marker of ocular myopathy in TAO patients.

The platelet membrance glycoprotein plays a key role in the adhesion,aggregation and release of platelet.It is the specific molecular marker for platelet activation.Many studies have confirmed that platelet membrane glycoprotein CD62P may be more sensitive and specific to reflect the occurrence of coronary artery development,CD62P level is positively correlated with the severity.A variety of traditional Chinese medicine can lower the CD62P level,inhibit platelet activation and the treatment play an important role in the treatment.

Objectives: To study safety method of control of blood glucose in perioperation patients with malignant gastrointestinal tumor and diabetes. Methods: The twenty eight cases with malignant gastrointestinal tumor and diabetes were analyzed retrospectively. Results: The patients with diabetes were safely controled in blood and urine glucose during perioperetion.There were no significant changes in serum lipids.The excretions of urea nitrogen in urine increased 24 hours after operation.The body weights declined and plasma proteins decreased after operation. Conclusions: The nutritional support is necessary and of feasibility in patients with malignant tumor and diabetes during perioperation.It is a key step to control blood glucose by using insuline.The nutritional support can protect function and structure of oragans.

To try to find out the possible use of histochemistry in the prenatal diagnosis in first trimester of pregnancy, 20 kinds of enzymes in chorionic villi from 6th to 9th week of gestation which are related to inborn errors of metabolism were investigated and graded according to their histochemical reactive intensity; the enzymes listed below: (1). ?-glucuronidase, (2). ?-galactosidase, (3). arylsulfatase, (4). ?-N-acetylglucosaminidase, (5). 3?-hydroxysteroid dehydrogenase, (6). NADH dehydrogenase, (7). adenosine triphosphatase, (8). alkaline phosphatase,(9). acid phosphatase, (10). creatine phosphokinase, (11). glutamic dehydrogenase, (12). aldolase, (13). xylitol dehydrogenase, (14). alcohol dehydrogenase, (15). xanthine oxidase, (16). catalase, (17). ornithine carbamoyl transferase, (18). lipase, (19). cholinesterase, (20). ?-glutamyl transpeptidase. The experimental results show that the last 6 kinds of enzymes present negative reactions. Since the his- tochemical reactions of the first 14 kinds of enzymes are positive, it is possible that they can be used for the prenatal diagnosis of inborn errors of metabolism caused by dificiency of corresponding enzymes. The results also show that compared with biochemical method, histochemical method has the advantages of requiring smaller amount of chorionic villi, being without contamination by maternal cells, simplicity and rapidity.

Objective:To produce a fusion protein(ICOS-Ig)between extracellular portion of human ICOS and Fc portion of mouse IgG 2a and study on its biological activity.Methods:cDNA encoding the extracellular domain of human ICOS was prepared by RT-PCR from the RNA of the stimulated human peripherial blood mononuclear cells. The Fc portion of mouse IgG2a was cloned by PCR from the vector that contains the sequence-encoding Fc portion of mouse IgG2a.Two resulting amplified PCR products were ligated into a secrection mammalian expression vector, pSecTag2/Hygro A. The recombined vector was transfected into CHO cells by lipofectamine2000.Results:RT-PCR demonstrated the integration and mRNA synthesis of fusion gene. ELISA and Western blot analysis showed the expression of ICOS-Ig and its molecular weight was between 43-66 kD, its concentration was 5-25 ?g/ml. FACS analysis assured that ICOS-Ig had ligand specific binding activity. Addition of ICOS-Ig to MLR resulted in inhibition of T-cell proliferation and IL-2,IFN-? secretion.Conclusion:The fused gene ICOS-Ig was constructed and expressed successfully. It had the bioactivity of inhibition of T cell proliferation and cytokine secretion.

Protein-protein binding is the basis of virus and host cell interactions. With the application of technology of studying protein interactions, more knowledge of replication and pathogenesis of hepatitis C virus (HCV) was acquired. Non-structure protein 5B(NS5B) of HCV is a kind of viral protein, which plays an important role in replication of HCV. However, the effect of NS5B is not clear. To investigate the biological function of NS5B, we performed yeast two hybrid to look for proteins in hepatocytes interacting with NS5B. We constructed NS5B bait plasmid by cloning the gene of NS5B into pGBKT7, then transformed it into yeast AH109(a type). The transformed yeast was mated with yeast Y187(? type)containing liver cDNA library plasmid in 2?YPDA medium. Diploid yeast was plated on synthetic dropout nutrient medium (SD/-Trp-Leu-His-Ade) containing x-?-gal for screening. Thirty-three colonies were selected and sequenced. Among them, two colonies were new genes with unknown function. The preliminary successful cloning of gene of protein interacting with NS5B paved the way for the study of the physiological function of NS5B and its associated protein.
