Objective:To compare the effect of misoprostol respectively with sublingual administration and rectal administration in the treatment of postpartum hemorrhage. Methods:Totally 72 pregnant women were randomly divided into two groups with 36 cases in each. The sublingual group was given misoprostol 600 μg under the tongue immediately after the front shoulder of baby was delivered, while the rectal group was given misoprostol 600μg into rectum deeply. The amount of blood loss in 2 hours and 24 hours after the de-livery and the adverse reactions were compared between the two groups. Results: The postpartum hemorrhageon in 2 hours and 24 hours of the sublingual group was significantly less than that of the rectal group, and the incidence of postpartum hemorrhage in the sub-lingual group was significantly lower than that of the rectal group, and the difference was statistically significant (P<0. 05). After the treatment, the incidence of adverse reactions between the two groups had no significant difference (P>0. 05). However, the incidence of shiver in the sublingual group was significantly higher than that in the rectal group, and the difference was statistically significant ( P<0. 05). Conclusion:The preventive effect of misoprostol with sublingual administration on postpartum hemorrhage after natural vagi-nal delivery is better than that with rectal administration, which is safe and convenient, and worthy of promoted application in clinics.

BACKGROUND:The previous researches indicate that, shock waves can enhance the proliferation of T-cells and the expression of interleukin (IL)-2 through a mechanism that involves p38 mitogen activated protein kinase (MAPK)activation.OBJECTIVE: To investigate if adenosine triphosphate (ATP) release is an underlying mechanism through which low-density shock waves (LDSWs) augment T-cell function.DESIGN: Controlled repetitive measurement by groups, taking cells as subject.SETTING: Department of Orthopedics, the First Hospital of Jilin University.MATERIALS: KDE-2001 Extracorporeal Shockwave Lithotripter (Beijing Zhongke Jian An Meditechs Co., Beijing, China).p38 MAPK inhibitor SB203580 1 mg (BioSource Inc., Camarillo, CA); p38 MAPK kit for detecting phosphorylation (Cell Signaling Technology, Inc. U.S.A.); P2 receptor inhibitor suramin 50 mg (BIOMOL Research Laboratories Inc., PA) was prepared into 0.02 mol/L solution by 1.749 2 mL IMDM. ATP enzyme: apyrase 200 U (Sigma, U.S.A.); P2X7 receptor antagonist KN-62 (BioSource Inc., Camarillo, CA); ATP Bioluminescence Assay Kit CLS Ⅱ (Roche Diagnostics GmbH,Mannheim, Germany).METHODS: The experiment was carried out in the Orthopedic Laboratory of the First Clinical Hospital in Jilin University from January 2005 to December 2006. ①An Extracorporeal Shockwave Lithotripter (at 7 kV generator voltage, 0.3 μF capacitance, 23 MPa positive pressure, 0.18 mJ/mm2 energy flux density) was applied for LDSWs treatment ranging from 50 to 400 impulses. ②ATP release into the culture supernatant from Jurkat T-cells or human peripheral blood mononuclear cells (PBMCs) was determined with a specific ATP Bioluminescence Assay Kit. ③Negative control group excluded antagonist or inhibitor. Human PBMCs were used to determine the effect of LDSWs on activated T-lymphocyte proliferation. Human Jurkat cells were used to study the effects of LDSWs on IL-2 expression. Expression and phosphorylation of p38 MAPK in Jurkat T-cell were measured by Western Immunoblotting with anti-p38 MAPK antibodies and anti-p38 MAPK phospho-specific antibodies that recognized the phosphorylation (on Thr180/Tyr182).MAIN OUTCOME MEASURES: extra-cellular ATP release, IL-2 expression in cell suspension, cellular proliferation and the phosphorylation of p38 MAPK.RESULTS: ①ATP release under the condition without LDSWs was obviously lower than that with LDSWs of 100, 150,200, 250, 300, 360 and 400 impulses (P < 0.01), and ATP release increased with the LDSWs impulse.②Compared with negative control group, the additions of apyrase, KN-62 or suramin attenuated the 3H-TdR incorporation of the phytohemagglutinin-stimulated PBMCs or CD3/CD28-stimulated Jurkat T-cells, which were effected with LDSWs of 100,150, 200, 250, 300, 330 impulses at 0.18 mJ/mm2 (P< 0.01). IL-2 expression in the cellular supernatant was also significant increased (P < 0.01). ATPase, KN-62 or suramin all decreased the effect of LDSWs on p38 MAPK of Jurkat T-cells.CONCLUSION: ①LDSWs deform cellular membranes but have no effect on organelle, which results in ATP release from Jurkat cells. Exogenous ATP release activates P2X7 receptor and p38 MAPK, and increases IL-2 expression. LDSWs enhance T-cell proliferation and IL-2 expression through a mechanism that involves ATP release, P2X7 receptor and phosphorylized p38 MAPK activation. ②The release of ATP plays a key role in the mechanism through which LDSWs regulate the function of T cells.

Objective To explore the dynamic changes of endothelial barrier antigen (EBA) and vascular endothelial growth factor (VEGF) expressions in cerebral cortex under the condition of blood-brain barrier damage in rats following radi?ation-induced brain injury, which provided clinical references. Methods Forty-eight clean grade male SD rats were divid?ed into the control group and 7 d, 14 d, 28 d after brain irradiation group (n=12 for each group) by using stochastic indicator method. The radiation-induced brain injury model was established by using electronic computer X-ray tomography tech?nique. The 3%Evans blue (EB) was injected into rats according to the dose of 3 mL/kg via the tail vein, then the blood ves?sels of cerebral cortex were exposed after having a craniotomy. EB extravasation was detected by microcirculation micro?scope. The permeability of blood-brain barrier was evaluated by using microscope vascular camera device. The expressions of EBA and VEGF in the cerebral cortex were measured by immunohistochemistry staining in each group. Results Both of EB extravasation and VEGF expression in rat cerebral cortex were significantly increased in injury group at day 7, 14 and 28 after brain irradiation compared with those of control group (P<0.05), and which were gradually decreased from day 7 to day 28 after brain irradiation. There were significant differences in EB extravasation and VEGF expression between the injury subgroups (P<0.05). There was a positive correlation between EB extravasation and VEGF expression (r=0.898, P<0.001). The expression levels of EBA were decreased at different time points in injury groups compared with those of control group (P<0.05), and gradually increased from day 7 to 28 after injury. There were significant differences in expression levels of EBA between injury subgroups (P<0.05). The expression of EBA was negatively correlated with EB extravasation (r=-0.866, P<0.001). Conclusion The increases of blood-brain barrier permeability have important relation to the decreases of EBA expression and the increases of VEGF expression after radiation-induced brain injury.
