Objective To investigate the route of minimal invasive sling procedures and evaluate their safety. Methods Tension-free vaginal tape (TVT),TVT-obturator (TVT-O) and posterior intravaginal sling (P-IVS) procedure were performed on five fresh pelvis.4% formaldehyde was used to preserve the cadavers and colored latex was injected into the vessels.An anatomic study and measurements between the trocars and related vessels or organs were carried out.Results There was no complication during all injections.The distance between TVT trocar and pubic vessels,the bladder,external lilac vessels and obturator vessels were 0.6,0.6,4.2 and 4.3 cm,respectively.Out of control of TVT trocar,the axial rotation or lateral diversion of TVT handle could injure these structures.We found during TVT-O operation,the retropubic space was not violated.The right placement of introducer was very important. When the beginning point was too deep into the anterior vaginal wall,2.2 cm proximal to urethral meatus or on a horizontal plane with a 35° angle relative to the urethral sagittal plane,the introducer would enter the retropubic space or perforate the upper posterior zone of the obturator membrane,where the obturator vessels and nerves exit the obturator canal.Based on our study,the diversion of P-IVS trocar would damage the rectum,and the pudendal vessels and nerves were relatively safe.Conclusions The TVT trocar passes the retropubic space and may injure the important vessels or organs.The route of TVT-O inside-out operation is stable and the retropubic space is not violated.The blunt design in the P-IVS trocar tips is helpful to reduce injury.

Objective To investigate the effects of lovastatin on MAPK activity in MCF 7 breast cancer cells. Methods After MCF 7 cells were treated with 4, 8 and 16 ?mol/L lovastatin for 48～72 h, the expressions of ERK1 and p38 MAPK proteins were detected by Western blotting. Their phosphorylation levels were observed by kinase activity assay. Results MCF 7 cells treated with different doses of lovastatin for 48～72 h had no significant effect on the protein level of ERK1, but the activities of ERK1 and the P38 MAPK proteins were down regulated at 72 h after treatment. Conclusion Lovastatin may down regulate the activity of MAPK in MCF 7 cells by means of inhibiting the mevalonate metabolism pathway and/or affecting phosphorylation levels.

Objective To evaluate continuous improvement of portable domestic pelvic floor neuromuscular electrical stimulation on the pelvic floor function of patients with stress urinary incontinence after short-term pelvic floor electrophysiological treatment in hospital.Methods Totally 60 women with stress urinary incontinence were recruited for this randomized controlled trial.The control group including a total of 30 patients,only received 4 weeks pelvic floor electrophysiological treatment in the hospital.Family consolidation treatment group (experimental group) including 30 patients,after 4-week treatment in hospital,received 12-week of pelvic floor neuromnuscular electrical stimulation using portable electrical stimulator at home under the guidance of doctors.In post-treatment 6 months and 9 months,1-hour pad test was measured for urine leakage,pelvic floor electrical physiological parameters were assessed,and subjective improvement of symptoms of urinary incontinence were evaluated.All these data were analysed to compare the effect of the two groups.Results In 9 months after treatment,average change of urine leakage,the control group and experiment group were (75±24)％ versus (99±3)％,the difference was statistically significant (P＜0.01).In the experiment group,strength of type Ⅰ muscle (4.4±0.7),strength of type Ⅱ muscle (4.8±0.4) and pelvic floor dynamic pressure [(96± 12) cmH2O,1 cmH2O=0.098 kPa] were better than those of control group [3.2± 1.0,4.3 ± 0.9,(86 ± 10) cmH2O,respectively],the differences were statistically significant (P＜0.01).Subjective outcome,the control group and experiment group were (6.5 ±2.9) versus (1.8 ± 1.7),subjective outcome between the two groups had significant difference (P＜0.01).Conclusion After short-term pelvic floor electrophysiological treatment in hospital,the portable domestic pelvic floor neuromuscular electrical stimulation in patients with stress urinary incontinence is helpful to continuous improvement of pelvic floor function.
