    Objective To investigate the effects of phytoestrogen α-zearalanol (α-ZAL) on vascular function in ovariectomized hyperhomocysteinemic rats. Methods Hyperhomocysteinemia was induced by fed with high-methionine diet. 40 adult female Wistar rats were assigned randomly into 5 groups: (1) Control (Con); (2) 2.5%Methionine (Met); (3) Ovariectomy+2.5%Methionine (OVX+Met); (4) Ovariectomy+2.5%Methionine+α-ZAL (OVX+Met+α-ZAL); (5) Ovariectomy+2.5% Methionine + 17β- estradiol (OVX+Met+17β-E2). 12 weeks later, blood was collected to analyze plasma estradiol and Hcy levels. Thoracic aortas were isolated to detect the response to phenylephrine (PE), acetylcholine (ACh) and sodium nitroprusside (SNP). Results The plasma Hcy levels were elevated in all rats fed with 2.5% methionine diets, especially in the OVX+Met group. In a dose-dependent manner, PE elicited significantly greater contraction in thoracic aorta rings taken from rats of OVX+Met than that taken from other groups and ACh elicited significantly less percentage relaxation in thoracic aorta rings. There was no significant difference in response to SNP between groups. Conclusion α-ZAL could remarkably improve vascular function in ovariectomized HHcy rats via attenuating elevation of plasma Hcy and endothelial cells damage, which is similar to 17β-E2.

    Objective To examine the effect of VEGF165 on expressions of JAGGED-1and NOTCH1 and the relationship between these expressions and epithelial- mesenchymal transition (EMT) induced by TGF-β1. Methods Cultured HK2 cells were incubated with TGF-β1(5μg/L) in the absence (group T) or presence (group T+V) of VEGF165 (100μg/L),respectively. Expressions of α-SMA and JAGGED-1mRNA were assessed with RT-PCR and the protein expressions were assessed with Western Blot at different time points,respectively. In the other experiment, HK2 cells were divided into four groups: negative control, incubated with TGF-β1(5μg/L) along, with VEGF165 (100μg/L) along, or with TGF-β1(5μg/L) and VEGF165 at different concentrations (0.1, 1, 10, 100μg/L) for 24 hours. Confocal microscope was used to detect expressions of α-SMA and E-cadherin. Protein and mRNA expressions of α-SMA, JAGGED-1and NOTCH1 were assessed with RT-PCR and Western Blot, respectively. Results Protein expression of both α-SMA and JAGGED-1decreased significantly in group T+V at 24h and 48h when compared to group T (P<0.05). VEGF165 reversed TGF β1-induced inhibition of E-cadherin and promotion of α-SMA, JAGGED-1and NOTCH1 significantly (P<0.05). Conclusions The results of the present study indicated that VEGF165 may partially inhibits TGFβ1-induced EMT of HK2 cells in vitro, which is probably contributed to the repression of JAGGED-1and NOTCH1 expressions. Further study is still needed.

    Objective To identify the pathogenic mutation in a large Chinese family with Charcot-Marie-Tooth disease (CMT). Methods Medical history of the proband and a detailed family history were collected. Necessary physical examination and nerve conduction velocity/EMG testing were performed to establish the diagnosis of CMT and a primary classification. Genomic DNA was extracted from peripheral blood samples of 16 family members. Five genetic loci for six CMT1 subtypes were screened by linkage analysis using microsatellite markers. Quantitative PCR was used to detect the genomic duplication encompassing the peripheral myelin protein 22 gene (PMP22). Results The CMT phenotype was transmitted in this family in an autosomal dominant pattern. Slow nerve conduction velocity (10-30m/s) was observed in all of the four patients who participated in the electrophysiologic testing. By linkage analysis, all CMT1 subtypes were excluded except the CMT1A and CMT1E locus, both of them involving the PMP22 gene on chromosome 17p11.2 region. Heterogeneous duplication of the PMP22 gene was detected in patients, but not in unaffected family members. Conclusion The disease in the family was ascertained to be CMT1A, and was caused by the PMP22 duplication.

    Objective: To evaluate the related factors for adverse maternal and fetal outcome among women with HELLP syndrome (hemolysis,H, elevated liver enzyme, EL, low platelet count, LP).Methods: We retrospectively analyze maternal and fetal medical records of pregnancy complicated HELLP syndrome from January 1, 2005 to December 31, 2009. Related factors included maternal age, parity, gestational age at diagnosis, adverse maternal and fetal outcomes. Statistical analysis was performed with the χ2 test analysis.Results: A total of 32 pregnant women with HELLP syndrome were reviewed. The incidence of HELLP or ELLP was 2.16% among the women with severe pre-eclampsia (32/1484). Gestational age at diagnosis was about 32 weeks and 4 days, with a peak frequency between the 27th and 37th gestational weeks. In about 84.4% of the cases, the HELLP syndrome develops before delivery. The rests develops within 48 h after delivery. The incidence of maternal complication, such as eclampsia, abruption placenta, postpartum bleeding, acute renal deficiency was higher among women with HELLP syndrome as compared with ELLP. The incidence of HELLP was significantly associated with a platelet nadir below 50x109/L (p<0.05). High incidence of fetal and neonatal death was present before 30 weeks of gestational age and with intrauterine growth restriction. High incidence of HELLP syndrome was also present in women without regular care during pregnancy. Conclusions The maternal adverse outcome of HELLP was higher than ELLP. There was a significant association between a platelet nadir below 50x109/L and the severity of HELLP. The perinatal mortality and morbidity was high before 30 weeks. Regular care during pregnancy may play an important role in prevention maternal and fetal adverse outcomes.
