Objective To investigate the level of knowledge,attitude and practice(KAP)of pelvic floor dysfunction(PFD)and its influencing factors in pregnant women and provide reference for further health education for pregnant women. Methods Totally 637 pregnant women were investigated by Knowledge-Attitude-Practice (KAP)scale for PFD. Results The average scores of KAP in pregnant women were(31.68 ± 7.73),(16.41 ± 4.01) and (10.57 ± 3.00) respectively. About 85.6% of the pregnant women had interest in knowledge of PFD. Educational background,willing to understand knowledge of PFD,and gestational age were dominant factors affecting KAP of women with PFD. Conclusions The awareness rate of PFD and compliance rate of pelvic floor muscle function exercise in pregnant women are low. Effective measures should be taken to prevent PFD for pregnant women.

OBJECTIVETo observe the vasodilating effect of adrenomedullin 2 (ADM2) by antagonizing angiotensin 1 (Ang II), and to explore its mechanism.

METHODSEighteen male, 180-200 g SD rats were randomly divided into 3 groups (n = 6): control group, Ang II (150 ng/(kg x min)) group and Ang II (150 ng/(kg x min)) + ADM2(500 ng/(kg x h)) group. Mini-osmotic pumps filled with peptide were implanted in the back of rats subcutaneously. After two weeks, the blood pressure was measured by the way of carotid intubation. The plasma was collected for the detection of nitric oxide (NO) content and the activity of endothelial nitric oxide synthase (eNOS). The in situ oxidation of fluorescent dye dihydroethidium (DHE) was used for detecting superoxide in rat arteries. The rat isolated arterial rings were made for studying the vasodilating effect of ADM2. Human umbilical vein endothelial cell line EA. hy 926 cells were cultured and their intracellular reactive oxygen species (ROS) were evaluated by probe DCFH-DA.

RESULTSADM2 dramatically decreased the blood pressure in angiotensin II-induced hypertension rat model, enhanced plasma NO content and the activity of eNOS and reduced superoxide formation in vessel walls. ADM2 also induced relaxation of the vascular rings preconstricted by Ang II in a concentration-dependent and endothelium-dependent manner. In cultured vascular endothelium, ADM2 ameliorated the ROS generation induced by Ang II.

CONCLUSIONAdrenomedullin 2 relaxed blood vessels by antagonizing angiotensin II-induced oxidative stress and improving the vascular endothelial function.

OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).

METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.

RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).

CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.
