Objective To investigate the relationship of S100B protein expression and the pathogenesis of early-onset and late-onset preeclampsia.Methods Sixty patients with preeclampsia who received caesarean section at Qingdao Municipal Hospital from October 2010 to September 2011 were enrolled in this study.Thirty cases were early-onset preeclampsia( referred as early-onset preeclampsia group,＜ 34 weeks),and the other 30 cases were late-onset preeclampsia (referred as late-onset preeclampsia group,≥34 weeks).Thirty women who received caesarean section because of pelvic structural deformities,breech presentation,macrosomia and social factors were included as the control group.The expression of S100B mRNA in the placenta was detected by reverse transcription ( RT)-PCR.The expression of S100B protein in the placenta was detected by immunohistochemistry.Results ( 1 ) S100B mRNA was expressed in the trophoblasts of preeclampsia and control groups.The expression of S100B mRNA in early-onset preeclampsia group (0.73 ±0.11 ) was significantly higher than the control group (0.58 ±0.08) and lateonset preeclampsia group (0.64 ±0.10,P ＜0.05 ).There was no significant difference between late-onset preeclampsia group and the control group ( P ＞ 0.05 ).(2) S100B protein was expressed in the plasma membrane and cytoplasm of the trophoblasts,correlated positively with the brownish yellow and brown particles inside the cells.It was expressed in all the three groups.Immunohistochemistry revealed that the expression of S100B protein in the placenta of early-onset preeclampsia group was 100％ (30/30),significantly higher than those of late-onset preeclampsia group and the control group,in which the positive rate were 70％ (21/30) and 63％ (19/30) respectively (P ＜0.05).There was no difference between late onset preeclampsia group and the control group (P ＞0.05).Conclusion Early-onset and late-onset preeclampsia may have different etiology and pathogenesis.S100B may be a factor in the pathogenesis of early-onset preeclampsia.

The binding of pefloxacin mesylate (PFLX) to bovine lactoferrin (BLf) and human serum albumin (HSA) in dilute aqueous solution was studied using fluorescence spectra and absorbance spectra. The binding constant K and the binding sites n were obtained by fluorescence quenching method. The binding distance r and energy-transfer efficiency E between pefloxacin mesylate and bovine lactoferrin as well as human serum albumin were also obtained according to the mechanism of Förster-type dipole-dipole nonradiative energy-transfer. The effects of pefloxacin mesylate on the conformations of bovine lactoferrin and human serum albumin were also analyzed using synchronous fluorescence spectroscopy.

Purpose To clarify the morphologic changes and significance of interstitial cells of Cajal-like cells in the bladder of diabetic guinea pig.Methods The experimental guinea pigs were induced by a single intraperitoneal injection of streptozotocin(STZ).The diabetic guinea pig model, who were made succesful for 4 weeks, were detected through the urodynamic evaluation.The distribution of ICCs-like cells in the detrusor, which were taken from these guinea pigs,were quantitatively analyzed after frozen section and indirect immunofluorescence methods and observed by electron microscopy.Results In the diabetic group, the maximum detrusor pressure was signifently lower than controls (P＜0.01), maximum bladder capacity, compliance, residual volume and leak point pressures was significently higer than controls (P＜0.05 or P＜0.01);In detrusor, compared with control, the ICCs-like cells of diabetes group showed significently decreased in quantity. In diabetic bladder, the quantity of gap junctions between ICCs-like cells and cells around,such as smoth muscle cells,terminal nerves and other ICCs-like cells,decreased significently.And more cavities and less organoids occurred in cytoplasm of diabetic ICCs-like cells. Mitochondria became swollen or even disapeared, accompanied with swollen endocytoplasmic reticulum.Conclusion The decrease and injures of ICCs-like cells in bladder may be one of the mechanisms resulting in urodynamic changes of diabetic cystopathy.

BACKGROUNDTo evaluate the inhibitive effect of combination of 3TC with Ara-AMP against HBV in vitro.

METHODSUsed 2.2.15 cell as target cell. With radioimmunological technique and blot slot, the inhibitive effect of 3TC, Ara-AMP and the combination of both against the HBsAg, HBeAg and intracellular HBV DNA were investigated.

RESULTSThe inhibitive ratio of Ara-AMP against HBsAg, HBeAg was 45.48% and 41.46% respectively when its concentration was 400.0 microgram/ml. Although 3TC also has inhibitive effect in its experimental concentration, its effect is weaker. When Ara-AMP 50.0 microgram/ml was combined with 3TC 1.25 and 5.00 microgram/ml respectively, the inhibitive ratio against HBsAg were 19.92% and 17.32% respectively. Compared with using same concentration 3TC alone, the difference of results was significant (P<0.05). But when compared with using the same concentration Ara-AMP alone, the difference of results had no statistical significance (P <0.05). Remarkable inhibitive effects of combination of 3TC with Ara-AMP against HBeAg were n ot found. When 3TC 5.00 microgram/ml was combined with Ara-AMP 12.5 and 50.0 microgram/ml respectively, the inhibitive ratio against HBV DNA was 45.90% and 50.36% respectively. Comparing the content of HBV DNA in these groups with that of control group and the groups using the same concentration 3TC and Ara-AMP alone, the differences were significant (P <0.05).

CONCLUSIONSCombination of 3TC with Ara-AMP could enhance the inhibitive effects against HBV DNA.
