Background Epilepsy in children seriously affects the quality of life and learning ability of children.And it is very important for repairing the brain function of children after seizure.In this study ,we will investigates the neuroprotective effects of NGF and FPS-ZM1 by measuring HMGB1of hippocampus and serum after intervening the rats with NGF and FPS-ZM1. It would provide theoretical basis for the treatment of brain injury caused by epilepsy. Methods 130 Wistar male young rats were randomly divided into three groups: Group A (normal control group including 31 rats), group B (epilepsy group including 33 rats), group C (NGF group including 33 rats), group D (FPS-ZM1 group including 33 rats).9 living rats were randomly selected at 3hours,24hours and 72hours after the intervention from each group, blood samples and the hippocampus were taken .The expression of HMGB1 in hippocampus was measured by Western-blot, and the content of HMGB1 in serum was measured by enzyme-linked immunosorbent assay (ELISA). Results The expression of HMGB1 in hippocampus and serum at each time point of group B was significantly higher than that of group A (P 0.05). Conclusion HMGB1 was significantly increased in hippocampus and serum of epileptic rats, it was suggested that HMGB1 was involved in the inflammatory process of epilepsy and HMGB1 could be used as a marker of brain injury degree after seizure. NGF and FPS-ZM1 had the effect of repairing the brain after seizure. FPS-ZM1 is superior to NGF in the protection of nervous system.

Background Recent evidence suggests early screening of preeclampsia and small-for-gestational-age (SGA) would benefit pregnancies followed by subsequent prophylactic use of aspirin. Multi-marker models have shown capability of predicting preeclampsia and SGA in first trimester. Yet the clinical feasibility of combined screening model for Chinese pregnancies has not been fully assessed. The aim of this study is to evaluate the applicability of a multi-marker screening model to the prediction of preeclampsia and SGA in first trimester particularly among Chinese population. Methods Three thousand two hundred seventy pregnancies meeting the inclusion criteria took first-trimester screening of preeclampsia and SGA. A prior risk based on maternal characteristics was evaluated, and a posterior risk was assessed by combining prior risk with multiple of median (MoM) values of mean arterial pressure (MAP), serum placental growth factor (PLGF) and pregnancy associated plasma protein A (PAPP-A). Both risks were calculated by Preeclampsia PREDICTOR™ software, Perkin Elmer. Screening performance of prior and posterior risks for early and late preeclampsia by using PREDICTOR software was shown by Receiver Operating Characteristics (ROC) curves. The estimation of detection rates and false positive rates of delivery with both preeclampsia and SGA was made. Results Eight cases developed early preeclampsia (0.24%) and 35 were diagnosed as late preeclampsia (1.07%). Five with early preeclampsia and ten with late preeclampsia later delivered SGA newborns (0.46%); 84 without preeclampsia gave birth to the SGAs (2.57%). According to ROC curves, posterior risks performed better than prior risks in terms of preeclampsia, especially in early preeclampsia. At 10% false positive rate, detection rates of early and late preeclampsia were 87.50 and 48.57%, detection rates of early and late SGA were 41.67 and 28.00%, respectively. For SGA, detection rates in cases with preeclampsia were much higher than those in absence of it. Conclusions This study demonstrates that combined screening model could be useful for predicting early preeclampsia in Chinese pregnancies. Furthermore, the performance of SGA screening by same protocol is strongly associated with preeclampsia.

Background Thyroid-stimulating hormone (TSH) and free thyroxine (FT4) reference intervals are essential for screening and diagnosing thyroid dysfunction during pregnancy. The aim of this study was to establish method- and trimester-specific TSH and FT4 reference intervals in pregnant Chinese women using the Beckman Coulter UniCel™ DxI 600. Methods A cross-sectional dataset analysis was performed. A total of 3507 participants were recruited, and 2743 were eligible for analysis to set reference intervals. TSH, FT4, and thyroid peroxidase antibody (TPOAb) levels were analyzed with the Beckman Coulter UniCel™ DxI 600 Access® immunoassay system. Ranges between the 2.5th and 97.5th percentiles were defined as reference intervals for TSH and FT4. Results The calculated reference intervals for the first, second, and third trimesters were TSH: 0.06-3.13, 0.07-4.13 and 0.15-5.02 mIU/L, respectively, and FT4: 8.72-15.22, 7.10-13.55 and 6.16-12.03 pmol/L, respectively. Conclusions Our reference intervals for TSH and FT4 are distinct from the ranges reported in the DxI 600 instruction manual and previously reported data, confirming the importance of method-specific reference intervals.
