ObjectiveTo investigate the relationship between platelet-derived growth factor (PDGF)-B and pre-eclampsia or eclampsia by comparing the expression of PDGF-B mRNA and PDGF-BB protein in the placentas from pregnant women with normal pregnancy,pre-eclampsia or eclampsia.Methods The expression of PDGF-B mRNA and PDGF-BB protein were respectively determined with RT-PCR and immunohistochemistry combined with the analysis of computer microphotography in the placentas from 20 mild pre-eclampsia (mild pre-eclampsia group),20 severe pre-eclampsia (severe pre-eclampsia group),3 eclampsia (eclampsia group) and 20 normal pregnancy (control group).ResultsThe expression of PDGF-B mRNA and PDGF-BB protein in the placentas of mild pre-eclampsia group,severe pre-eclampsia group and eclampsia group ( 1.56 ± 0.30 and 1.32 ± 0.34,1.91 ± 0.28 and 2.00 ± 0.41,2.57 ± 0.06 and 2.73 ± 0.15)were higher than those of control group ( 1.38 ± 0.25 and 1.01 ± 0.26) with significant differences (P< 0.01 ).The expression of PDGF-B mRNA and PDGF-BB protein in the placentas of severe pre-eclampsia group and eclampsia group were higher than those of mild pre-eclampsia group (P < 0.01 ).The expression of PDGF-B mRNA and PDGF-BB protein were positively correlated with the degree of the disease (r =0.691,0.797,P <0.01 ).ConclusionsPregnant women with pre-eclampsia and eclampsia have higher expression of pDGF-B in the placentas.PDGF-B may play an important role in the development and progression of pre-eclampsia and eclampsia by promoting atherogenesis in the placental vessels.

OBJECTIVE: To study the effects of Anxin Granules on dyslipidemia in rabbits caused by high fat plus high cholesterol diet. METHODS: Thirty-two healthy New Zealand male white rabbits were randomly divided into 4 groups: normal control group, untreated group, Zhibituo Tablet-treated group and Anxin Granule-treated group. Rabbits in the normal control group were fed with regular chow, while rabbits in the other three groups were fed with high fat plus high cholesterol diet. Zhibituo Tablets and Anxin Granules were administered to the rabbits in Zhibituo Tablet-treated group and Anxin Granule-treated group at a daily oral dose respectively. At the end of the 10th week, the levels of serum total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein A(1) (ApoA1) and apolipoprotein B (ApoB) were tested in each group, and the ultrastructures of the aorta were also observed by an electron microscope. RESULTS: Anxin Granules could reduce the levels of TC, TG, LDL-C and ApoB. The results observed by electron microscope showed that, as compared with the untreated group and the Zhibituo Tablet-treated group, the atherosclerosis of aorta in the Anxin Granule-treated group was lighter. And it was found that there were few lipid droplet vacuoles in cytoplasm of the endothelial cells, and various cell organs and elastic membrane were existed, but no lipid droplet vacuoles in cytoplasm of the medial smooth muscle cells. CONCLUSION: Anxin Granules can regulate the metabolism of blood lipid and inhibit the formation of atherosclerosis caused by hyperlipidemia in rabbits.

Objective: To investigate the effect of Shenmai Injection (Radix Ginseng Rubra, Radix Ophiopogonis) on angiogenesis and the expression of proliferating cell nuclear antigen (PCNA) in tumor tissue, and the mechanism of it in the treatment of tumor. Methods: The mouse tumor model was used to investigate the effect of Shenmai Injection on tumor growth on the whole. The expression of von Willebrand factor (vWF) and PCNA in tumor tissue was studied by means of immunohistochemistry. Results: Shenmai inhibited the tumor growth and reduced microvessel density and the expression of PCNA in tumor tissue. Conclusion:Antiangiogenesis is one of the mechanisms of Shenmai Injection in treatment of tumor.

Objective To observe the effect of Puerarin on the level of tau phosphorylation in the olfactory bulb of Alzheimer's disease rat brain, and explore the underlying molecular mechanism.Methods ① Twenty-two male SD rats were randomly divided into the normal control group, model control group and Puerain-treated group.The levels of tau-1, PS396 and tau-5 in the olfactory bulb were detected by Western blotting.② Twenty male SD rats were randomly divided into model control group, low-dose Puerarin (40 mg·kg-1·d-1), medium-dose puerarin (80 mg·kg-1·d-1) and high-dose puerarin (160 mg·kg-1·d-1) groups.The levels of tau-1 and PS396 phosphorylation in the olfactory bulb were detected by Western blotting.③ The level of GSK-3β phosphorylation in the olfactory bulb of the normal control group, model control group A and puerain-treated group was detected by Western blotting.Results ① It was shown by Western blotting that the relative expression of tau-1 was significantly decreased in the olfactory bulb of the model group A(0.49±0.07)rat brain compared with the normal control group(0.85±0.03)(P<0.01), and the level of tau-1 was obviously higher in the puerarin-treated group(0.58±0.03)compared with that of the model group A(P<0.05).The differences of the levels of tau-5 and PS396 in the olfactory bulb were insignificant among the 3 groups.②Compared with the model group B, the expression of tau-1 in the olfactory bulb was significantly enhanced in the low-, medium-and high-dose of puerarin group: (0.39±0.09)vs(0.69±0.11),(0.55±0.11),(0.70±0.04);and the level of PS396 was significantly decreased in the olfactory bulb of low-dose puerarin group(0.36±0.07) compared with the model group B(0.55±0.05)(P<0.01).③Compared with the normal control group(0.96±0.07), the ratio of pS9-GSK-3β/tGSK-3β was obviously decreased in the olfactory bulb of the model group A(0.51±0.12),while that was significantly increased in the puerarin group(0.62±0.03) compared with the model group A(P<0.01).Conclusion Puerarin can attenuate AD-like tau hyperphosphorylation in the olfactory bulb of Alzheimer's disease rat brains, and decreased activity of GSK-3β might be involved in the effects of puerarin on tau hyperphosphorylation.

Objective To explore the association of galactose-deifcient IgA1 levels with clinical features, and further to provide guidance for individualized treatment of HSP. Methods According to the clinical symptoms and curative effect, 57 children with HSP were divided into four groups:non-HSPN group (n=26), HSPN group (n=7), refractory HSP group (n=7) and remission group (n=17). In non-HSPN group, 12 cases received glucorticoid therapy and 14 cases did not. Serum galactose-de-ifcient IgA1 (Gd-IgA1) concentrations were detected using a Helix aspersa-lectin-based enzyme-linked immunosorbent assay (ELISA), and the total IgA1 levels were measured by ELISA. Results The serum Gd-IgA1 level was signiifcantly higher in 40 HSP children who were not cured than that in remission group and control group (P<0.05). However, there was no difference in Gd-IgA1 level between remission group and control group (P>0.05). Compared with the control group, the serum Gd-IgA1 level was signiifcantly higher in HSPN group, non-HSPN group and refractory HSP, and children with refractory HSP had signiifcantly higher Gd-IgA1 level than children in non-HSPN group (P<0.05). No signiifcant difference in Gd-IgA1 level was found either between HSPN group and refractory HSP group or between HSPN group and non-HSPN group (P>0.05). Furthermore, in non-HSPN group, the serum Gd-IgA1 level in HSP children who were not treated with glucorticoid was signiifcantly higher than that in HSP children treated with glucorticoid (P<0.05). Conclusions The serum Gd-IgA1 level is associated with the disease activ-ity and curative effect of HSP, especially in children with refractory HSP, and it is thus likely to be a new non-invasive disease activity marker for guiding the proper usage of glucocorticoid and immunosuppressants in HSP children.
