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 feasibility of the double venipuncture instead of central venous catheter as a temporary vascular access in hemodialysis.Methods The upper arm below the 1/3 was tied a tourniquet,and fistula needle directly punctured the vein in the middle of the elbow.After the success of the puncture,elastic bandage was replaced by a tourniquet,and the ball movement was done by imitating the blood donation member for blood donation at hand gripping a ball or elements as the artery blood lead.Another elbow vein or lower limb saphenous vein was punctured.Thirty patients using double venipuncture dialysis or central venous catheter dialysis 2 weeks or more were randomly selected into each group,and biochemical and renal function was measured before dialysis.Results All of 1 282 patients who were newly into the blood dialysis,mature arteriovenous fistula was in 8 patients (0.6％,8/1 282),deep venipuncture to insert the central venous catheter was in 542 patients(42.3％,542/1 282),using the double venipuncture was in 732 patients (57.1％,732/1 282).The flow of blood was 180-200 ml/min,the avalible time was 1-2 months.The serum creatinine,blood urea nitrogen,calcium,phosphorus and carbon dioxide combining power had no significant difference between two groups (P ＞ 0.05).Conclusions The majority of patients with double venipuncture blood flow can satisfy the need of dialysis.Because the operation is simple,no recycling and may reduce the deep venipuncture,it is an ideal temporary vascular access.

Objective To examine the effects of different doses of midazelam on ED50 of emulsified isoflurane and to determine the type of interaction between them for hypnosis by isobelographic analysis in rats. Methods One hundred and twenty-five adult male SD rats weighing 240-300 g were randomized into 5 groups (n=25 each): group Ⅰmidazolam (M); group Ⅱ emulsified isnflurane (Ⅰ); group Ⅲ ,Ⅳ ,Ⅴ, 1/4, 1/2 and 3/4 ED50 of midazelam for hypnosis + emulsified isoflurane (MI1 , MI2, MI3). Up-and-down sequential experiment was used to determine ED50of midazolam and emulsified isoflurane for loss of righting reflex in group Ⅰ -Ⅴ . The intial dose of midazolm was 17.3 mg/kg in group M. The initial doses of emulsified isoflurane (120 mg/ml) were 0.55 (in group Ⅰ, 0.22 (MI1), 0.19 (MI2) and 0.12 ml/kg (MI3) respectively. In group MI1-3 midazolam was injected over 15 seconds and after an interval of 2.5 min emulsified isoflurane was injected over 10 s. ED50 was calculated using Dixon-Mood method. Isebolographic and algebraic analyses were used to determine the type of interaction between midazolam and emulsified isoflurane. Results The five groups were comparable with respect to M/F sex ratio and body weight. The Edso of midazolam was 26.0 mg/kg in group M. Midazolam 6.5, 13.0 and 19.5 mg/kg were given in group MI1 , MI2 and MI3 respectively. The ED50 of emulsified isoflurane was 0.67 (ingroup Ⅰ), 0.30 (MI1), 0.22 (MI2) and 0.18 ml/kg (MI3) respectively. The isobolographic analysis indicated that with increasing doses of midazolam, the Edw of emulsified isoflurane decreased progressively in a non-linear fashion. The isobolographic and algebraic analyses demonstrated that the interaction between midazolam and emulsified isoflurane was synergistic for hypnosis. Conclusion The hypnosis is synergistic when midazolam 6.5,13 mg/kg are combined with emulsified isoflurane and additive when midazolam 19.5 mg/kg is combined with emulsified isoflurane.
