Manometric comparison of anorectal function after posterior vaginal compartment repair with and without mesh

Quality-of-life improvements in patients after various surgical treatments for pelvic organ prolapse

OBJECTIVE

To compare the improvements in quality of life of patients with pelvic organ prolapse (POP) treated using various surgical methods.

MATERIALS AND METHODS

The PUBMED, MEDLINE and Cochrane Library online databases were searched using the keywords "pelvic organ prolapse", "surgery", "PFDI-20" and "PFIQ-7" for articles published from January 2010 to December 2022 that included quality-of-life scores before and after surgery.

RESULTS

Forty-nine articles were include. The mean postoperative PFDI-20 and PFIQ-7 scores decreased by 67.50% and 76.98%, respectively, compared with those before surgery. In 76.9% of patients, this change did not decrease with increased postoperative time. The improvement rate in PFDI-20 scores after colpocleisis did not differ statistically from that after sacrocolpopexy and was significantly higher than that after other procedures. The improvement rate in PFIQ-7 scores after colpocleisis did not statistically differ from that after high uterosacral ligament suspension and was significantly higher than that after other procedures. The improvement rate in PFDI-20 scores after transvaginal mesh-based repair (TVM) did not significantly differ from that after sacrospinous ligament fixation and was significantly lower than that after other procedures except traditional vaginal wall repair. The improvement rate in PFIQ-7 scores after TVM did not significantly differ from that after new procedures and was significantly lower than that after other procedures.

CONCLUSIONS

Surgical treatment can significantly improve the quality of life of patients with POP. Colpocleisis may offer more advantages than those of other surgical procedures, and improvement was lower after TVM than after other procedures.

Correlations between Mitofusin 2 Expression in Fibroblasts and Pelvic Organ Prolapse: An In vitro Study

BACKGROUND

Both Mitofusin 2 (Mfn2) and pelvic organ prolapse (POP) are related to aging. The aim of the present study was to investigate the variations of Mfn2 expression in the uterosacral ligaments of patients with and/or without POP and their correlations with the expression of procollagen.

METHODS

Fibroblasts were cultured using tissue specimens that were harvested from the uterosacral ligaments of POP and non-POP (NPOP) patients (n = 10 for each group) from September 2016 to December 2016. The Cell Counting Kit-8 (CCK-8) assay was used to compare the differences in cell proliferation between the two groups. Relative quantitative reverse transcription-polymerase chain reaction and Western blotting assays were employed to assess the differences in the mRNA and protein expression levels of Mfn2 and procollagen 1A1/1A2/3A1 between the two groups. The changes in procollagen expression were assessed following the downregulation of Mfn2 in the POP group using RNAi. The data were assessed with independent sample t- test or general linear model univariate analysis using the SPSS 13.0 software.

RESULTS

The results from CCK-8 assay indicated that cell viability in the POP group was significantly lower compared with that of the NPOP group (td5, 7, 9, 11= -5.925, -6.851, -9.129, and -9.661, respectively, all P < 0.001, from D5 to D11). The mRNA and protein expression levels of Mfn2 in the cultured fibroblasts of the POP group were significantly higher compared with those of the NPOP group (mRNA: t = 2.425, P = 0.032; protein: t = 2.392, P = 0.037, respectively), whereas only the expression levels of procollagen 1A1/1A2/3A1 were significantly higher in the NPOP group (mRNA: t = -2.165, P1A1 = 0.041; t = -2.741, P1A2 = 0.026; t = -2.147, P3A1 = 0.045, respectively; protein: t = -2.418, P1A1 = 0.029; t = -2.405, P1A2 = 0.033; t = -2.470, P3A1 = 0.012, respectively). The expression levels of procollagen in the POP group increased following the downregulation of Mfn2.

CONCLUSIONS

The proliferation rate and cell viability of the fibroblasts in the POP group were significantly lower compared with those in the NPOP group. In the POP fibroblasts, Mfn2 expression was increased, while procollagen expression was decreased.

Individual and combined use of ginsenoside F2 and cyanidin-3-O-glucoside attenuates H2O2-induced apoptosis in HEK-293 cells via the NF-κB pathway

Ginsenoside F2 and cyanidin-3-O-glucoside synergistically inhibited H₂O₂-induced apoptosis in HEK-293 cells through mitochondria-mediated apoptotic and NF-κB pathways.
