This study examined in vitro effect of lipoxin A(4) (LXA(4)) on interleukin-1β (IL-1β) production of monocytes and its possible mechanism in severe preeclampsia (PE). Peripheral venous blood was drawn from 15 patients with severe preeclampsia (PE group) and 20 normal pregnant women (control group) to prepare monocytes which were then treated with LXA(4) at different concentrations of 0, 10, 100 nmol/L respectively. IL-1β level in the supernatant of monocytes was detected by enzyme linked immunoassay. The [Ca(2+)](i) of monocytes was measured by laser scanning confocal microscopy. The results showed that the IL-1β level and the [Ca(2+)](i) of monocytes in the PE group were significantly higher than those in the control group. LXA(4) significantly decreased the generation of IL-1β in a dose-dependent manner in the PE group. After treatment with 100-nmol/L LXA(4), in the PE group, the [Ca(2+)](i) concentration of monocytes was significantly reduced. It was concluded that LXA(4) may inhibit the IL-1β production of monocytes from severe preeclampsia women by inhibiting extracellular calcium influx.

Objective To study the role of P38 mitogen-activated protein kinase(P38 MAPK) activation in high level glucose-induced microvascular hyperpermeability.Methods Rats were induced to diabetis by intraperitoneal injection of streptozotocin(STZ).The rats were divided into 5 groups,including normal,diabetes,control,MKK6b(A) and MKK6b(E) groups.The permeability coefficient to albumin(Pa) was measured in venules of in vivo mesenterium using a fluorescence ratio technique;Morphological changes of microvascular endothelial cell were monitored by observing fluorescence of F-actin stained with rhodamine-phalloidin.Results The permeability of diabetic rats was obviously increased.The activation of P38 MAPK by MKK6b(E) could increase microvascular permeability in normal rats,and the inhibition of P38 MAPK by MKK6b(A) could inhibit hyperpermeability of diabetic rats.Conclusion The activation of P38 MAPK induced by hyperglycemia may play a role in diabetic microvascular hyperpermeability.

BACKGROUND:Bone marrow mesenchymal stem cel s (BMSCs) are the focus of research on the proliferation and metastasis of hepatocel ular carcinoma cel s. By genetic engineering techniques, the hepatocel ular carcinoma cel s can be induced to reduce the expression of bioactive factors, thereby seeking suitable intervention targets for improving the interventional effect of BMSCs. OBJECTIVE:To silence the expression of transforming growth factor beta1 (TGFβ1) and osteopontin (OPN) in high metastatic potential hepatocel ular carcinoma cel s (MHCC97-H) fol owed by co-culture with BMSCs and then to observe the change of MHCC97-H cel invasion ability as wel as the interventional effect of BMSCs on the animal model of hepatocel ular carcinoma tissue MHCC97-H by fluorescence imaging in vivo. METHODS:MHCC97-H cel s were divided into four groups:MHCC97-H group was set as a blank control group, and MHCC97-H NC siRNA as negative control group, and MHCC97-H siRNA TGFβ1 and siRNA OPN were experimental groups. Transwel s assay was carried out for co-culture experiments. After 48 hours of co-culture, crystal violet staining was performed for cel counting in three randomly selected fields of vision. Combined with the red fluorescence protein gene, MHCC97-H cel lines in each group were inoculated via the right subaxil ary subcutaneous transplantation to make a tumor model in nude mice. When the tumor volume was up to about 50 mm3, BMSCs were injected into the tumor in the nude mice, and 4 weeks later, fluorescence images were analyzed using software for fluorescence intensity. Frozen hepatocel ular carcinoma tissue sections were taken for 4’,6-diamidino-2-phenylindole staining and fluorescence microscope observation. RESULTS AND CONCLUSION:Cel counting results showed that BMSCs significantly decreased MHCC97-H cel s after gene silencing, and crystal violet staining showed that the migration ability of MHCC97-H cel s was significantly decreased. Tumor volume shown by the fluorescence imaging was significantly reduced after the OPN gene transfection, the fluorescence intensity was lower than that in the other groups, and quantitative results showed that the absorbance value of OPN shRNA cel s decreased significantly compared with other groups, indicating the BMSCs exhibit best interventional effectiveness in OPN-silenced MHCC97-H cel s. Pathological sections showed that BMSCs were mainly distributed in the tumor necrosis area, and the fluorescence expression in the OPN siRNA group was more than that in the TGFβ1 siRNA group and the blank control group, indicating that after OPN gene silencing of MHCC97-H cel s, the distribution of BMSCs in the tumor was increased. To conclude, it is able to reduce the invasive ability of hepatocel ular carcinoma cel s by inhibiting the expression of OPN and TGFβ1 factors, and OPN silencing may be more conductive to BMSCs biotherapy.

Objective To explore the immunomodulatory mechanism of 2-(-2-benzofuranyl )-2-imidazoline(2-BFI) in rat model of experimental autoimmune encephalomyelitis (EAE).Methods Fifty fe-male Sprague-Dawley(SD) rats were randomly divided into five groups by random digit table , including con-trol group(n=10), EAE model group(n=10), low dose 2-BFI group(1.5 mg/kg, n=10), median dose 2-BFI group (3 mg/kg, n=10) and high dose 2-BFI group (6 mg/kg, n=10).The SD rat model of EAE was induced by immunizing with a guinea pigs′spinal cord homogenate ( GPSCH ) .The severity of EAE was scored according to the signs and symptoms .Pathological changes were observed through Hematoxylin-eosin staining, and then the degrees of inflammatory infiltration were evaluated .The number of activated neuroglia that expressed GFAP and iba 1 in lumbar cords was counted by immunohistochemistry .The expressions of IL-1β, IFN-γ, IL-4 and IL-10 in cervical cords were measured by ELISA .Results Compared with EAE group, rats in the low, median and high dose 2-BFI treatment group had lower incidence of EAE , prolonged latency and decreased CNS inflammation , but only the median dose group showed significant alleviation in clinical symptoms and decrease in CNS inflammatory cell infiltration (P<0.05).Immunohistochemical re-sults showed that the numbers of activated microglia were significantly inhibited ,but the numbers of activated astroglia were increased in the rats treated with median dose of 2-BFI in comparison with the EAE group ( P<0.05).Results of ELISA demonstrated that expressions of IL-1βand IFN-γin 3 mg/kg 2-BFI treated group were significantly decreased compared with that in the EAE group (P<0.05), but expressions of IL-4 and IL-10 were remarkably increased(P<0.05).Conclusion 2-BFI at median dose of 3 mg/kg has a benefi-cial neuroprotective effect on rats with EAE , and its mechanism might be related to immunodulation .
