Objective To establish a flow cytometric method for assay of platelet aggregation induced by shear stress(SIPA) and investigate its clinical value. Methods After the whole blood was subjected to a certain shear stress by a rotational viscometer, the platelets were activated and aggregated. Then the fluorescence antibody CD61 PerCP was added to stain the platelets. The free platelets and aggregates were counted respectively by flow cytometry, thereby the ratio of platelet aggregation was calculated. Results Shear stress-induced whole blood platelet aggregation varied with the increase of shear stress and time of stress. Only a small amount of platelet aggregation was detected at relatively low shear stress of 100S -1, and it was increased at 500S -1. However, a significant increase occurred with 2 000S -1. It approached to the maximum value (58.4%?5.3%) at 3 000S -1 with exposure of 3min, which was higher than the values at 100S -1(9.4%?1.3%)and 500S -1(26.4%?3.2%). At the same time, the aggregates increased in size and became more compact with increase in the shear stress and prolongation of time. High shear stress induced platelet aggregation(H-SIPA) was significantly enhanced in patients with AMI, cerebral infarction, TIA or diabetes, all of them were susceptible to coagulopathy, compared with normal control. Conclusion The results indicated that shear stress could induce platelet aggregation directly, and the degree of SIPA had positive correlation with the stress stength and exposure time.The measurement of H-SIPA was of some clinical value in the diagnosis of arterial thrombosis.

The Infectious hypodermal and hematopoietic necrosis virus (IHHNV) and Taura syndrome virus (TSV) are two important shrimp viruses in cultured shrimp in America. These two viruses were transmitted to China at the beginning of the 21st century. In this study, 214 shrimp samples of Penaeus vannamei were collected from seven different areas of China and tested by PCR for IHHNV and TSV infection. The results showed that there were a high prevalence of IHHNV (65.42%) and low prevalence of TSV (3.27%) in the tested samples. Several samples were found to be co-infected with these two viruses. A 3 kb fragment of 7 positive IHHNV samples and a structure protein region (ORF2) of three TSV positive samples were amplified and sequenced. The sequence comparison indicated that both IHHNV and TSV sequenced in China have a low genetic variations compared with the prototype IHHNV and TSV from Hawaii. Phylogenetic analysis showed that TSV isolates were clustered into two groups, Asia and America group, which was genetically correlated to geographic distribution.

Objective To explore the relationship between plasma mannose-binding lectin (MBL), lipopolysaccharide (LPS) and body mass index in pregnant women with gestational diabetes mellitus (GDM). Methods 45 newly diagnosed GDM pregnant women and 45 healthy women (control group) were selected in this study. Plasma concentration of MBL and LPS were measured. All the groups were sub-divided into obesity (BMI ≥ 25 kg/m2) and non-obesity (BMI < 25 kg/m2) subgroup. The relationships of levels of plasma LPS, MBL with BMI were analyzed. Results The level of plasma MBL in GDM group was significantly lower than that in control group(P < 0.05), while the concentration of LPS in serum was much higher than that in healthy pregnant women (P < 0.05). Pearson analysis showed the level of MBL in GDM group was negatively correlated with BMI(r=-0.28, P<0.05), serum LPS concentration was positively correlated with BMI(r = 0.62, P < 0.05) and LPS was negatively correlated With MBL(r = -0.43, P < 0.05) . The above correlations were not found in control group. Conclusion Serum MBL and LPS maybe two important risk factors for those pregnant women being overweight, and could offer great significance for the prevention and treatment of GDM.
