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.

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.

Objective To evaluate the difference between nodal and extra-nodal diffuse large B-cell lymphoma (DLBCL) in clinical-pathological feature and prognosis.Methods The clinical data of 134 cases of DLBCL patients were reviewed and analyzed.Results The DLBCL patients accounted for 52.14 ％ (134/257) of non-Hodgkin lymphoma of the same period and the extra-nodal DLBCL patients accounted for 69.4 ％.The proportion of stage Ⅲ/Ⅳ disease in extra-nodal DLBCL and nodal DLBCL were 55.9 ％ (52/93) and 75.6 ％(31/41),respectively.Elevated LDH was reported in 33.3 ％ (31/93) of extra-nodal DLBCL and 58.5 ％ (24/41)of nodal DLBCL Other clinical characteristics such as B symptoms,bulky disease,elevated ESR,ECOG scores and IPI scores were not significantly different between these two groups (all P ＞ 0.05).No difference in the frequency of GCB and non-GCB subtypes was observed between extra-nodal and nodal DLBCL (P =0.623).The 3-year overall survival rates and 3-year progression free survival rates for extra-nodal and nodal DLBCL were 73.2 ％,55.2 ％ (P =0.065) and 46.3 ％,44.1％ (P =0.748).Conclusions The morbidity of extranodal DLBCL is high.Primary extra-nodal DLBCL patients present early-stage disease and normal LDH more frequently than the nodal DLBCL,while no significant difference in the frequency of pathological subtypes and 3-year OS and PFS is observed between these two groups.

Objective:To investigate the effect of thermal conductivity on the apical sealing ability of different dental gutta-percha cones during the warm vertical condensation obturation.Methods:Four kinds of dental gutta-percha cones were used in this study:Bio-GP points (BP,B&L,Korea),large-tapered gutta-percha (DP,DENTSPLY,America),PROTAPER Universal gutta-percha points (DPP,DENTSPLY,America) and mtwo gutta-percha points (VP,VDW,Germany).Volume differences method was used to determine the main components and the thermal conductivity determinator was used to measure the thermal conductivity of these dental gutta-percha cones.Furthermore,20 cones randomly selected from each kind of dental gutta-percha cones.And 10 cones of each dental gutta-percha cones,which were cut out the part of 4 mm in length from the apical end,were heated (200 ℃) from the upper end without compression,and the temperature of the gutta perchacones surface was monitored in time by the infrared thermal imager during the whole heating process.In addition,the rest of the 10 cones of each dental gutta-percha cones were used to obturate the root canal in the transparent root canal resin model using warm vertical condensation technique.The cross-sectional surface was observed by stereomicroscope (× 40) at 1 mm and 3 mm from the working length and the gutta-percha obturation area proportion was measured and analyzed.The data were analyzed by one-way ANOVA.Results:The proportion of inorganic fillers (80.90％ ± 1.14 ％) (P ＜ 0.05) and the thermal conductivity (2.247 ± 0.002)of DP was siguificantly higher than BP (79.28％ ± 3.88％,1.179 ± 0.003),DPP (68.46％ 5.09％,0.604 ±0.001),VP (78.86％ ± 1.87％,1.150 ±0.001) (P ＜0.05).During the thermal obturation without compression at the setting temperature (200 ℃),DP could achieve 65 ℃ beyond 1 mm from the heating point,and BP,DPP and VP only reached 65 ℃ within 1 mm.After warm vertical condensation obturation,all the groups showed increased gutta-percha obturation area proportion.At the position of WL-3,DP (96.89％ ±0.03％) showed significantly higher proportion of gutta-percha obturation area than BP (95.47％ ±0.06％),DPP (95.21％ ±0.03％) and VP (95.15％ ±0.03％) (P ＜ 0.05).Conclusion:DP contains more inorganic fillers,possesses higher thermal conductivity,and leads a better apical sealing ability than BP,DPP and VP at the position of WL-3 during warm vertical condensation obturation.
