Objective To investigate the significance of detection of blood coagulation and fibrinolytic indexes before and after delivery.Methods 212 cases in the postpartum hemorrhage group(bleeding amount ≥500 mL)and 235 cases in the normal deliver-y group were retrospectively analyzed.The prothrombin time(PT),international normalized ratio(PT-INR),activated partial throm-boplastin time(APTT),thrombin time(TT),fibrinogen(FIB),D-dimer(DD),blood platelets(PLT)and hemoglobin(HB)were de-tected before delivery and at 72 h after delivery.85 women with the physical examination were selected as the healthy group.Results Before delivery,PT/PT-INR,APTT,TT,PLT and HB in the normal delivery group were lower than those in the healthy group, while FIB and DD were higher than those in the healthy group;PT/PT-INR,APTT,TT and DD in the postpartum hemorrhage group were higher than those in the normal delivery group,while FIB and PLT were lower than those in the normal delivery group. At 72 h after delivery,there was no statistically significant differences in PT/PT-INR,APTT,TT and DD between the normal de-livery group and the healthy group(P >0.05),but FIB was higher than that in the healthy group;PT/PT-INR,APTT,TT and DD in the postpartum hemorrhage group were higher than those in the normal delivery group,while FIB,PLT and HB were lower than those in the normal delivery group.Conclusion Dynamically monitoring the change of the blood coagulation and fibrinolysis indexes before and after delivery has important significance in preventing postpartum hemorrhage and thrombosis.

OBJECTIVETo investigate the apoptosis of bladder cancer cell 5637 induced by pseudolaric acid B in vitro and its mechanism.

METHODThe cell proliferation was detected by MTT assay;the cell cycle was measured by flow cytometry; the cell apoptosis was observed by flow cytometry with Annexin V-FITC/PI double staining; the expressions of survivin protein and caspase-3 protein were detected by Western blot assay.

RESULTIt showed that pseudolaric acid B remarkably induced apoptosis of 5637 cell line. Moreover, pseudolaric acid B suppressed survivin and up-regulated caspase-3 expression.

CONCLUSIONPseudolaric acid B inhibits the proliferation and induces the apoptosis of 5637 cells. The molecular mechanism of pseudolaric acid B inducing the apoptosis of 5637 cells may be associated with its action of down-regulating the expression of survivin, and up-regulating the expression of caspase-3.

BACKGROUND/AIMS: Nausea, an unpleasant symptom of diabetic gastroparesis (DMGP), has been reported to be alleviated by needleless transcutaneous electrical acupuncture (TEA). Our study was designed to utilize electroencephalography (EEG) and electrogastrography (EGG) recordings to investigate the central and peripheral responses of TEA in the treatment of nausea in DMGP patients. METHODS: Eleven DMGP subjects underwent simultaneous EEG and EGG testing while grading the severity of nausea following 30-minute intervals of: (1) baseline, (2) visual stimulation (VS) to provoke more nausea, (3) active VS together with TEA, and (4) TEA alone, and a final 15-minute recording without any intervention. RESULTS: The nausea score was increased to 5.9 ± 1.5 with VS (P < 0.05, vs 3.5 ± 1.0 at baseline), then reduced to 3.5 ± 1.2 with VS plus TEA, and to 2.5 ± 1.3 with TEA alone, while it continued at a score of 2.9 ± 1.0 post TEA (all significant, P < 0.05, vs VS without TEA). The mean percentage of normal gastric slow waves was decreased to 60.0 ± 5.7% with VS (P < 0.05, vs 66.6 ± 4.5% at baseline), then improved to 69.2 ± 4.8% with VS plus TEA, and maintained at 70 ± 3.6% with TEA alone. During initial VS, EEG signals showed right inferior frontal activity as the prominent finding, but during VS with TEA, left inferior frontal activity predominated. CONCLUSIONS: In DMGP, TEA improves gastric dysrhythmia and ameliorates nausea. TEA treatment of nausea provoked by VS resulted in a change of dominance from right to left inferior frontal lobe activity. These data provide new understandings of peripheral and central mechanisms for nausea, and potential future directions for DMGP treatment approaches.
