Objective　To evaluate the efficiency of low molecular weight heparin(LMWH, fraxiparine) given as a single predialysis bolus injection with reused dialyzers in comparison with standard heparin(SH) administered with a continuous infusion. Methods　30 hemodialysis patients were studied in a radomized crossover fashion. Dialyzers fibrer bundle volumes(FBV), predialysis hemocrit and 2 h clearance of urea, creatinine were observed in the first, the fourth dialysis. The plasma heparin activities(anti-Fxa levels) were measured by the chromogenic substrate assay in 0 h, 2 h, 4 h of dialysis. Results　Significant increase (P<0.05) was seen in the number of dialyzer reuse in LMWH group compared with SH group; there was not significant decrease in dialysis FBV as well as 2 h clearance of urea, creatinine (P>0.05); in addition, the plasma heparin activity(anti-Fxa levels) were comparable in both groups after 2 h of dialysis, however, they were significantly higher after 4 h in the LMWH than those in the SH group (P<0.05). Conclusion　LMWH as a single bolus dose can prevent decrease in dialyzer clearance. It is clinically worthy of further popularity.

Objective To investigate the relationship between human epidermal growth factor receptor 2 (HER-2) gene amplification and protein expression in gastric carcinoma and its clinicopathological features. Methods Gene expression and protein expression of 98 gastric cancer patients were detected by fluorescence in situ hybridization (FISH), and immunohistochemistry (IHC) staining respectively. The relationship between gene amplification, protein expression of HER-2 and the clinicopathological characteristics were analyzed. Results In 98 cases of gastric cancer, there were 16.3 % (16/98) with gene amplification of HER-2, 83.7 % (82/98) without gene amplification of HER-2; 31.6 % (31/98) with negative expression of HER-2 protein, 59.2 % (58/98) with uncertain expression of HER-2 protein, 9.2 % (9/98) with positive expression of HER-2 protein. The coincidence rates of HER-2 protein expression and gene amplification were 96.7 % (30/31), 12.0 % (7/58), 88.9 % (8/9). The expression of HER-2 protein and gene amplification in gastric cancer was significantly correlated (P< 0.001). HER-2 gene amplification was not significantly correlated with gender, age, differentiation degree and depth of invasion (all P> 0.05), but with lymph node metastasis (P= 0.022). Conclusions The negative and positive expression of HER-2 protein have a high coincidence rate with gene amplification in gastric carcinoma. However, the results of IHC and FISH are different when the expression of HER-2 protein is uncertain. The amplification of HER-2 gene is associated with lymph node metastasis in patients with gastric cancer, which may provide an important reference index for determining the biological behavior of gastric cancer.

BACKGROUND: Hepatocyte growth factor (HGF) promotes neurite outgrowth from neocortical explants, and supports neuronal survival under serum-free condition. Thus, HGF can mediate neurotrophic function as a novel neurotrophic factor.OBJECTIVE: To establish an in vitro injury model with a semi-solid culture system for the purpose of improving the evaluation of neurite regeneration of transected spinal cord neurons from rat embryo, and investigate the effect of HGF on neurite regeneration.DESIGN: Randomized controlled study.SETTING: Hematology Laboratory of Radian Medical Institute of Academy of Military Medical Sciences of PLA.MATERIALS: The experiment was carried out at the Hematology Laboratory of Radian Medical Institute of Academy of Military Medical Sciences of PLA from August 2004 to May 2005. Wistar fetal rats of 14-16 days old were provided by Animal Center of Academy of Military Medical Sciences of PLA. Tail collagen was extracted from adult male Wistar rats with body mass of (250±50) g.METHODS: ① Rat tail type Ⅰ collagen substrate was prepared and spread on a culture dish, cut into about 0.5-1.0 mm3 slices, then spinal cord slices of 15-day-old fetal Wistar rat were explanted on the primary culture. Five days later, the outgrowing processes were severed, then a block of collagen, with the surface area of 2 mm2 and 200 μm away from the slice, was removed and the vacancy was replaced with a fresh collagen block of 2 μL after aspirating the medium. The fresh collagen block could be solidified and then fresh liquid medium was added as the secondary culture. The regeneration of neurite was observed by microscopy at 0, 1, 6,12 and 24 hours after severing. ② The medium was changed with 0.5% N3-conditioned medium. 10 μg/L HGF was added in the experimental group, and 0.5% N3-conditioned medium was added in the control group.The status of regeneration was evaluated by the average value of 3 longest regenerative neurites for each slice. There were 12 slices in each group.The status of neurite regeneration was calculated and was evaluated 24 hours later.MAIN OUTCOME MEASURES: ① neurite regeneration in situ; ②comparisons of neurite regeneration between control group and experimental group.RESULTS: ① Neurite regeneration in situ: The neurites disintegrated near the severing line immediately following the transection injury. This process persisted about 1-2 hours and the distance away from the severing line was about 20 μm. Then the proximal end of neurites would swell and thicken. At this time neurites stopped collapsing and neurite regeneration began. Their regenerating rate would quicken at 12 hours after severing. Regenerating neurites were more branching and curlier as compared with original neurites. ② Comparisons of neurite regeneration between control group and experimental group: The average length of regenerative neurites was more in the experimental group than that in the control group [(375±96) μm, (200±75) μm, P ＜ 0.05].CONCLUSION: ① We establish a simple, economic model to evaluate neurite regeneration. ② By this model, we prove that HGF can promote neurite regeneration.

The modern large-scale pyrosequencing technology is a revolution of DNA sequencing.One of the key points in this technology is to get an ATP sulfurylase immobilized on the surface of magnetic beads and with a high activity.Biotinylated ATP sulfurylase can be immobilized on magnetic beads coated with streptavidin through the specific conjunction between biotin and streptavidin, but using chemical modification method to biotinylate ATPS will affect the activity of the enzyme.ATP sulfurylase fused with the carboxyl terminal 87 residues of Escherichia coli biotin carboxyl carrier protein(BCCP87) was expressed in E.coli using fusion expression strategy.Results from Western blot analysis and SDS-PAGE analysis showed that the fusion protein could be biotinylated in vivo, and the molecular mass of the fusion protein was about 64 ku.The biotinylated ATP sulfurylase could be immobilized on the surface of magnetic beads coated with strepavidin, and the immobilized ATPS could be used for quantification of PPi and pyrosequencing.An effective enzyme for the large-scale chip-based pyrosequencing system was supplied.
