Objective To investigate the expression of growth arrest-specific protein 6 (Gas6) in the placenta and decidua tissues and its relationship with the pathogenesis of preeclampsia. Methods All the patients were recruited in Qilu Hospital of Shangdong University from October 2013 to June 2014. Among them, thirty-two women with early-onset severe preeclampsia who received cesarean section were assigned to the preeclampsia group, and thirty healthy pregnant women who received cesarean section were defined as the control group. Blood glucose, blood lipids, platelet count, D-dimer levels and other clinical indicators of the two groups were detected. Immunohistochemistry of SP was conducted to identify the localization of Gas6 protein in the placenta and decidua tissues. And reverse transcription (RT)-PCR was performed for quantitative analysis of Gas6 RNA expression in placentas. The correlations between placental Gas6 mRNA levels with clinical indicators were analyzed. Results (1) The gestational age at delivery, blood pressure, serum albumin, platelet count and birth weight of fetuses showed statistically significant differences between the two groups(P<0.05). (2) The Gas6 protein expressed in the cytoplasm and nucleus of the syncytiotrophoblasts and decidual cells in the placenta and decidual tissues of the two groups. (3) The Gas6 mRNA expression elevated significantly in the placenta of preeclampsia group (0.60 ± 0.38) when compared to that of the control group (0.34±0.22;P<0.05). (4) The expression of Gas6 mRNA was positively related with body mass index, diastolic blood pressure, systolic blood pressure, free fatty acids and creatinine (P<0.05), while it was negatively associated with serum albumin(P<0.05).

A strain of Prototheca species isolated from a case of meningitis was identified by routine morphologic and biochemical methods as well as amplification of the related genes, in which the 28S large-subunit (LSU) region of ribosomal RNA (rRNA) gene and intergenic space (ITS) were amplified with universal fungal primers. The small-subunit (SSU) rRNA gene was amplified with eukaryote-specific primers and Prototheca genus-specific primers. Then, compared the sequences with the ones posted on BLAST (www. ncbi. nlm. nih. gov/BLAST). The organism choice giving the closest match, up to 99%, was considered the most likely correct identification. It was found that this strain of fungus grew well at 25 ℃ or 37 ℃. Smooth,moist colonies with white color were observed on Sabouraud Dextrose Agar (SDA) and Potato Dextrose Agar (PDA). Microscopically, globular or ovoid cells, a number of round, ovoid shaped endospores could be observed. No hypha, ascus or blastic conidia was found upon cultivation on SDA. Based on the morphological characteristics, this isolate could be identified as Prototheca species. The identity with Prototheca wickerhamii was 2.9 % as demonstrated by the API 20C AUX system. Sequence analysis showed that the ITS gene was proved to be a complex structural region which was not suitable for the identification of Prototheca species, but the LSU and SSU rDNA regions showed 94% and 99.9% sequence identities with Prototheca zopfii var. hydrocarbonea (P. zopfii var. hydrocarbonea) respectively, indicating that the SSU rRNA gene sequence might be more reliable on than the LSU rRNA gene sequence for identification of Prototheca species.

Objective To investigate the expression of interleukin-37 (IL-37) in placenta tissue and its relationship with the pathogenesis of severe preeclampsia. Methods All the patients were recruited in Qilu Hospital of Shangdong University from November 2012 to November 2013. Among them, thirty patients with severe preeclampsia were assigned to the preeclampsia group, and thirty-one healthy pregnant women were assigned to the control group. Immunohistochemistry of SP was used to detect the IL-37 protein expression in placenta tissue of the two groups. The expression level of IL-37 in placenta tissue of the two groups was detected by western blot. Besides, reverse transcription(RT)-PCR was used to detect the expression of IL-37 mRNA. The correlation between the expression of IL-37 mRNA and the delivery gestational age, body mass index(BMI)was analyzed. Results (1) IL-37 were detected in the placenta of both the preeclampsia group and the control group, and the expression site mainly located in the syncytiotrophoblast, with a small amount in cytotrophoblast.(2)The expression levels of IL-37 protein in the preeclampsia group and the control group were 0.59 ± 0.39 and 0.88 ± 0.22, respectively. The IL-37 mRNA levels in the preeclampsia group and the control group were 0.55 ± 0.17 and 1.11 ± 0.21, respectively. Both decreased significantly when compared to the control group (P<0.05). (3) Significant correlation between the expression of IL-37 mRNA and the delivery gestational weeks(r=0.209, P>0.05) was seen neither in the preeclampsia group nor in the control group(r=-0.053, P>0.05). In the severe preeclampsia group, the pregnant women′s BMI had no significant correlation with IL-37 mRNA expression of placenta tissue(r=0.102, P>0.05), neither did the control group(r=-0.115, P>0.05). Conclusion IL-37 expression is significantly lower in severe preeclampsia placenta tissue than that in the normal pregnant women, which may play a protective role in the course of severe preeclampsia.
