ABSTRACT
One hundred and twenty nine patients with pelvic organ prolapse (stage Ⅲ to Ⅳ according to POP-Q staging) diagnosed in our hospital from January 2010 to December 2016 were enrolled,among whom 66 cases underwent vaginal hysterectomy plus vaginal anterior and posterior wall repair (TO group),63 cases underwent vaginal hysterectomy plus pelvic floor reconstruction with autologous tissue (AT group).Clinical parameters,perioperative and postoperative complications were analyzed.There was no statistically significant difference in intraoperative blood loss,indwelling urethral catheter time,length of hospital stay,and anal exhaust time between group AT and group TO (P＞O.05).The average operation time of group AT was significantly longer than that of group TO (P＜0.05).The postoperative rotation angle of urethra (UR),posterior vesicourethral angle (RVA),and bladder neck descent (BND) of group AT were significantly reduced (P＜0.05).The BND of group AT was significantly smaller than that of group TO 3 months and 12 months after the surgery (P＜0.05).There was no statistically significant difference in UR before and 12 months after surgery in group TO (P＞0.05),while the BND at 12 months after operation in group TO was increased compared to 3 months after operation (P＜0.05).There were significant differences in scores of PFIQ-7 and PISQ-12 before surgery and 12 month after surgery in both groups (P＜0.05).There was no statistically significant difference between the two groups in the incidence of postoperative recurrence and pressure incontinence (P＜0.05).It is suggested that the stability of pelvic floor anatomical structure after pelvic floor reconstruction with autologous tissue is better than that of the traditional surgery,especially for patients with severe pelvic organ prolapse.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the anti-metastasis effect of emodin on the pancreatic cancer in vitro and in vivo.</p><p><b>METHOD</b>Human pancreatic cancer cell line SW1990 was treated with different concentrations of emodin (10, 20, 40 micromol x L(-1)) for 2 h, the effects of emodin on the migration and invasion of SW1990 cells were examined by using wound assay and matrigel counting. Western blot was used to detect the protein expression of NF-kappaB and MMP-9 in SW1990 cells after various concentrations of emodin (10, 20, 40 micromol x L(-1)) treatment for 48 h. Metastatic model simulating human pancreatic cancer was established by orthotropic implantation of histologically intact human tumor tissue into pancreatic wall of nude mice, and then divided into three groups: control group, low-dose emodin group (L-EMO) and high-dose emodin group (H-EMO). Eight weeks after implantation, the presences of metastasis were evaluated respectively after the mice were sacrificed. Immunohistochemistry was used to detect the positive expression of CD34, NF-kappaB and MMP-9 in the tumors.</p><p><b>RESULT</b>Emodin suppressed the migration and invasion of SW1990 cells in a dose-dependent manner. Western bolt assay indicated that emodin down-regulated the expression of NF-kappaB and MMP-9 proteins in SW1990 cells. The incidences of metastasis were decreased significantly in L-EMO group and H-EMO group as compared with that in control group. The percentage of CD34, NF-kappaB and MMP-9-positive cells in the tumors were significantly reduced by the administration of emodin.</p><p><b>CONCLUSION</b>Emodin exerts anti-metastatic activity in pancreatic cancer both in vitro and in vivo, which may be related to down-regulation of NF-kappaB and MMP-9.</p>
