Objective:To analyze the levels of immune cytokine in peripheral blood(PB) and the expressions of immune related transcription factors in placenta cytotrophoblast,which in patients with pregnancy-induced hypertension(PIH).And to explore the effect of fetal-maternal immune tolerance on pregnancy-induced hypertension.Methods:50 cases patients with PIH were selected as the observation group,and 40 healthy people were chosen as the control group.Enzyme-linked immunoassay(ELISA) was performed to detect the levels of IFN-γ,IL-4,IL-17 and TGF-β in peripheral blood.Quantitative Real-time PCR(RT-qPCR) and Western blot were used to analyze the mRNA expressions and protein levels of T-bet,GATA-3,RORC and Foxp3 in placenta cytotrophoblast,respectively.Results:①Compared with the control group,the IFN-γ and IL-17 levels in peripheral blood in the observation group were obviously higher and the TGF-β level was greatly lower(P<0.05).There was no significant difference of IL-4 level between the two groups(P>0.05),but the ratios of IFN-γ/ IL-4 and IL-17/TGF-β in the observation group were larger than that in the control group(P<0.05).②Compared with the control group,the mRNA expressios and protein levels of T-bet and RORC in the observation group were increased significantly(P<0.05),but that of GATA-3 and Foxp3 were decreased greatly(P<0.05).Thus,the ratios of T-bet/GATA-3 and RORC/Foxp3 in the observation group were significantly larger than that in the control group(P<0.05).Conclusion:PIH is occurred with the imbalance of Th1/Th2 and Th17/Treg,and it might be associated with the mechanism of fetal-maternal immune tolerance disorder that induced by Th cells.

Objective To explore the mechanism of the interaction between sulfur dioxide(SO2) and bovine serum albumin (BSA). Methods The spectrum characteristic of the interaction between SO2 and BSA was studied by fluorescence quenching spectrum and three dimensional fluorescence spectrum. Results The binding constants and thermodynamic parameters of SO2 with BSA were calculated at different temperatures. The quenching mechanism of BSA by SO2 was determined,the result showed that it did not belong to dynamic quenching but belonged to static quenching,which produced the complex. The hydrophobic interaction and electrostatic force played a main role in the binding of SO2 with BSA and only about one binding site occurred in the reaction. There was a certain influence to the conformation of BSA after adding SO2. Conclusion The quenching reaction of BSA by SO2 was weak. SO2 dissolved in body fluid easily and then SO32-and HSO3-are generated in vivo.

Result The PVFP was significantly different between MS and ASD, including S、D、Ar、S-T (P

objective To evaluate the therapeutic efficacy of surgical and nonsurgical treatment and the clinical factors affecting the efficacy in traumatic optic neuropathy. Methods To analyse retrospectively the efficacy of recovery of visual acuity in 40 cases of traumatic optic neuropathy after treatment with transnasal endoscopic sphenoethmoidal optic canal decompression (28 cases) and drug therapy (12 cases). Results No significant difference existed between the therapeutic efficacy of surgery and that of drug therapy in patients with the visual acuity of LP～0.02. In surgery group,the therapeutic efficacy of the patients with visual acuity of LP～0.02 was better than that of the patients with no LP.The therapeutic efficacy of patients with duration shorter than seven days before sutgery is better than that of patients with duration longer than seven days. Conclusions The patients with serious traumatic comperssive optic neuropathy should not be treated with decompressive surgery and should not delay to at most seven days after injury.With or without the visual acuity of light perception of the affected eye surgery is usually an important factor affecting the therapeutic efficacy.
