Objective To find out the clinical predictive factors of preecfampsia.Methods A retrospective analysis was made on clinical data of 60 preec]ampsia (preeclampsia group) and 1 974 normal pregnant women (normal pregnant group).Multiple factor Logistic regression analysis was used to determine independent risk factors of preeclampsia.Results There were no significant differences in age,body mass index,pregnant history,occupation,pregnant condition,newborn gender,education background between normal pregnant group and preeclampsia group (P ＞ 0.05).There were significant differences in infertility history,preeclampsia history,antenatal care,combined with hypertention [4.3％ (84/1 974) vs.48.3％ (29/60),2.1％(42/1 974) vs.70.0％(42/60),98.2％(1 938/1 974) vs.80.0％(48/60),5.0％(98/1 974) vs.45.0％ (27/60),P ＜ 0.01 or ＜ 0.05].Multiple factor Logistic regression analysis showed that preeclampsia history,combined with hypertention,infertility history were the independent risk factors of preeclampsia.Conclusion The preeclampsia history,combined with hypertension and infertility history are the independent risk factors of preeclampsia which are available to identify patients with preeclampsia among high risk patients.

Hydrolysate of Meretrix meretrix soft tissue (HMST ) (20, 10g/kg ,po.for 14d ) could markedly inhibit the increase of serum total cholesterol(TC)and triglyceride(TG),enhance the content of high density lipoprotein cholesterol(HLD-C) ;reduced cholesterol(Ch)of the liver(for 28d)in hyperlipimic quail ;and it could also reduce whole blood viscosity in normal and hyperlipemic quail (for 21d).In addition.it could suppress the platelet aggregation induced by ADP in rabbits in vitro. The results show that HMST obviously decreased blood lipid and whole blood viscosity .inhibited platelet aggregation.

Objective To investigate the inhibitory effect of ginkgolide B (BN52021) on severe acute pancreatitis (SAP) via detecting the antagonistic effect of BN52021 on platelet-activating factor (PAF). Methods One hundred and eighty Wistar rats were randomly divided into control group (n = 60), SAP group (n = 60) and BN52021 group (n =60) according to the random number table. The 3 groups were divided into 6 subgroups at different time points after operation (1 h, 2 h, 3 h, 6 h, 12 h, and 24 h). The changes of serum amylase in each group were monitored. The expression of platelet-activating factor receptor (PAFR) mRNA and protein was detected by RT-PCR and Western blot, and the pathological changes of pancreatic tissues were observed. All the data were analyzed by one-way ANOVA. Results Serum amylase level and pathological results showed that it was successful in preparing SAP model. The serum amylase levels at postoperative hour 3, 6 and 24 were (4185 ±148) U/L, (3785 ± 124) U/L and (1360 ± 161) U/L in BN52021 group, which were significantly lower than those in SAP group [(4799 ± 107) U/L, (4920 ± 140) U/L, (2283 ± 127) U/L)]. The pathological scores at postoperative hour 3, 6, 12 were 5.95±0. 19, 5.55±0.36, 6.72±0. 30 in BN52021 group, which were significantly lower than those in SAP group (8.85 ± 0.39, 9.15 ± 0.55, 10.10 ±0. 65). The mRNA and protein expression of PAFR were gradually increased at the early stage (0.49 ± 0.09-0.71 ± 0.14 vs 0. 43 ～ O. 06-1.69 ± 0.06), and reached peak at postoperative hour 3. The expression levels of PAFR mRNA and protein in BN52021 group and SAP group at postoperative hour 3 had statistical difference among the 3 groups (F = 4.58, 6.24, P < 0.05). Conclusions The expression of PAFR mRNA and protein in the pancreatic tissue of SAP rats is dynamically changing. PAFR plays an important role in the occurrence and progression of SAP. BN52021 can reduce the expression of serum amylase and improve the pancreatic pathological changes, but it has no effect on the expression of PAFR in pancreatic tissue.

Objective To discuss the feasibility of using serum complement C5a and C5b-9 as predictive indicators of liver injury severity in traumatic rats with hemorrhagic shock.Method Fifry healthy male Wistar rats were randomly(random number)divided into normal group,model 1 hour group,model 3 hours group,model 6 hours group,and model 24 hours group.Plasma CH50,C5a and C5b-9 were detected by using enzyme-linked immunosorbent assay,and rate method was used for determination of plasma aspartate aminotransferase.Paraffin sections of hepatic tissues were used to observe the damage of liver.Results In the model l h group,the CH50 increased significantly and reached the highest value,it began to decline in 3 hours group,and it reached the lowest point in 24 hours group.Compared with the model 3 hours group,6 hours group,and 24 hours group,the level of CH50 in model 1 hour group increased more significantly(respectively P<0.05).A small amount of C5b-9 in the normal group was detected.In the model 1 h group,C5b-9 increased significantly and reach the peak compared with 3hours group,6hours group and 24 hours group,respectively(P<0.05),but in the model 3hours,it began to decline,and in 24 hours group,it reduced to minimum.C5a increased insignificantly in the model 3 hours group,6 hours group and 24 hours group,and peaked in 24 hours group compared with normal group(P<0.05).Aspartate aminotransferase in the model 1 hour group increased significantly and peaked in 24 hours group compared with other groups(P<0.05).Conclusions A large number of complements are activated in the seRing of hemorrhagie shock.C5b-9 and CH50 increase significantly in the early stage,and C5a.increases significantly in the later stage.C5b-9 can be considered as,an initiative factor of liver injury.The low levels of C5a in the early stage may be a mechanism of self-protection of the body.The high levels of CSa in the later stage may be a kind of decompensation,and C5a can be used as a late predictor of disease severity.

Objective To explore the role of cytokines on the pathogenesis of hypoxic-ischemic en-cephalopathy (HIE). Method The levels of peripheral blood interleukin (IL)-6, IL-8, tumor necrosis factor-alpha (TNF-α) in 40 HIE and 40 healthy neonates were detected at the 1st, 3rd and 7th day after birth by using radioimmunoassay. Results Compared with healthy neonates, at the 1 st, 3rd after birth, the level of peripheral blood IL-6 was decreased [(52.3±24.5)ng/L vs (80.1±28.6)ng/L and (56.9±28.5) ng/L vs (78.6±28.9)ng/L, respoctively], but IL-15 and TNF-α were increased [IL-8:(0.68±0.23)ng/L vs (0.47±0.13)ng/L and (0.63±0.22)ng/L vs (0.40±0.16)ng/L, TNF-α: (1.17±0.30)ng/L vs (0.91± 0.30) ng/L and (1.14±0.29)ng/L vs (0.96±0.34)ng/L]in HIE infants. Conclusion The changes of plas-ma levels of IL-6, IL-8 and TNF-α in neonatal HIE possibly play an important role in the pathophysiologic mechanisms of HIE.

To construct the eukaryotic expression plasmid of human PRX3 and measure its expression in the HEK-293FT cells, the full-length coding region of human PRX3 was cloned by PCR and inserted into the eukaryotic expression vector pcDNA4-Xpress (A). HEK-293FT cells were transiently transfected with the recombinant plasmid. Western blot and immuofluorescence were used to detect the expression of the fusion protein. In the experiment, restriction analysis identified the construction of the recombinant plasmid and the inserted sequence was identical with that published on GenBank. Western blot and immunofluorescence confirmed the expression of the recombinant protein in transfected HEK-293FT cells. It was concluded that the eukaryotic expression plasmid of human PRX3 was constructed successfully and the recombinant could be expressed efficiently in HEK-293FT cells, which provides a sound basis for the further study on human PRX3.

Endothelial progenitor cells (EPCs) are immature endothelial cells which have the capacity to proliferate, migrate and differentiate into mature endothelial cells from bone marrow to the peripheral circulation. EPCs have been shown to participate in postnatal endothelial repair and neovascularization of ischemic organs, and have been used as a new source of seeded cells in vascular tissue engineering. In this review, we focus on the origin, identification, property and function of EPCs as well as their application in vascular tissue engineering.
