ABSTRACT
Objective To explore the perfect operation method for patients with vaginal vault prolapse.Methods Twenty six patients with vaginal vault prolapse who underwent transvaginal mesh repair by Prolift from January 2008 to June 2010 were analyzed retrospectively.Results The interval time between the first operation and this morbidity of ten patients who had underwent total hysterectomy for none FPFD ( ie:hysteromyoma et al) was ( 115.2 ±51.67) months,but the interval of sixteen patients who had underwent traditional repair operation (ie:transvaginal hysteromyoma and/or colporrhaphia anterior-posterior) for FPFD was (24.38 ± 13.43) months,which was markedly shorter ( t =6.75,P ＜0.01).The interval time between the first operation and the 2nd operation of the ten patients was ( 142.8 ±59.04) months,but that of the sixteen patients was (62.13 ± 44.51 ) months,which was significantly shorter ( t =3.97,P ＜0.01 ).Their age and POP-Q staging had no difference ( P ＞0.05).All operations were successfully performed by one gynecologist.The average operation time was ( 60.96 ± 7.88 ) minutes,the average blood loss was ( 119.23 ±27.53) ml,and there was no concomitant injury.All patients were followed up of 3 ～24 months.No vaginal erosion and prolapse recurrence happened,and the cure rate was 100％.Conclusions The Prolift system appeared to be a relatively safe and effective alternative to conventional surgeries for the treatment of vaginal vault prolapse.However,long-term follow-up still need to be performed.
ABSTRACT
Objective To study the effect of lentivirus-mediated CCL5-RNAi on the biological behaviors of human breast cancer cells. Methods CCL5-specific siRNA gene was synthesized and cloned into the recombinant lentiviral vector, pGCSIL-GFP. Human high-metastatic breast cancer cells, MDA-MB-231, were infected by CCL5-siRNA recombinant lentivirus, which was set as KD group. Cells infected with CCL5-NC was as NC group, and cells cultured was as CON group. The expression of CCL5 mRNA and protein in MDA-MB-231 cells was detected by RT-PCR and western blot, respectively. Cell growth suppression and cell cycle was observed by MTT assay and fluorescence activated cell sorting (FACS). Colony formation and migration ability were determined by colony-rorming assay and Boyden chamber method. Results After infection of CCL5-siRNA recombinant lentivirus, the expression level of CCL5 mRNA and protein in MDA-MB-231 cells as well as the colony formation and migration ability decreased significantly, but cell's proliferation was not affected obviously. Compared with MDA-MB-231 (0.88± 0.15) and MDA-MB-231/CCL5-NC (1.00±0.07) cells, the expression of CCL5 mRNA in MDA-MB-231/ CCL5-siRNA decreased to 0.18±0.03, P<0.01. Compared with MDA-MB-231/CCL5-NC (1.82±0.18) cells, the expression of CCL5 protein in MDA-MB-231/CCL5-siRNA decreased to 0.33±0.13, P <0.01. Colony-forming assay and Boyden chamber method showed that the colony formation and migration ability of MDA-MB-231/CCL5-siRNA decreased markedly (P<0.05). The clone count in KD group was (0.33± 0.10), which was a significant decrease from (0.97±0.09) (NC group) and (1.04±0.07) (CON group), P<0.05. The number of cells that migrated through the chamber membrane of KD group (38± 15) was less than that of NC group (77±11, P <0.05) and CON group (69±9, P <0.05). However, MTT assay and FACS revealed that the proliferation of MDA-MB-231/CCL5-siRNA was not different from MDA-MB-231/CCL5-NC and MDA-MB-231 (P>0.05), the proliferation index (PI) of group KD, NC and CON were (0.48±0.02), (0.44±0.05) and (0.47±0.02) respectively. The difference was not statistically significant by multiple comparison (P>0.05). Conclusion CCL5-specific siRNA can specifically suppress the colony formation and migration of human high-matastatic breast cancer cells.
ABSTRACT
Objective To observe the relationship between psychological factor(anxiety and depression) and postpartum hemorrhage?mode and duration of labor. Methods Ninety two healthy nulliparas who had no gist of cesarean section were involved in our study. Their psychosis were evaluated with Self-rating Anxiety Scale(SAS) and Self-rating Depression Scale(SDS),according to which they were divided into two groups:high-score group and low-score group.All women were not interfered during the courses of delivery. Mode, duration of labor and postpartum hemorrhage were observed. Results Among the 92 nulliparas observed, the spontaneous delivery rate was 86.96% (80 cases) and the postpartum hemorrhage rate was 10% (8 cases). The scores of SAS and SDS of the low educational level group, the spontaneous group or the non-hemorrhage group were significantly lower than those of the high educational level group, the dystocia group or the hemorrhage group respectively. Moreover, the duration of first and the second stage of the high SAS score group or the high SDS score group was significantly longer than that of the low SAS score group or the low SDS score group,P
