Objective To investigate the prompt value of abnormal vaginal morphology on diagnosing pelvic organ prolapse . Methods Forty eight pelvic organ prolapse female patients diagnosed by pelvic organ prolapse quantification were enrolled in the pelvic organ prolapse group and 51 normal female volunteers were enrolled in the control group in this study. Pelvic MRI T2WI were performed in all cases. The vaginal shape were evaluated according to Delancey Ⅱ level on the transverse images, which were divided into two categories:normal morphology (H-shaped) and abnormal morphology(non H-shaped). The vaginal shape distribution of different prolapse degree(0,Ⅰ,Ⅱ,Ⅲ,Ⅳstage) and types(anterior,middle, posterior pelvic prolapse) were recorded. Chi-square test was used to analyse distribution difference of vaginal shape between the two groups. The ROC curve was used to analyse the diagnostic efficiency of abnormal vaginal morphology for diagnosing pelvic organ prolapse. Results In the control group, there were 40 cases with normal vaginal morphology and 11 cases with abnormal morphology mainly including W-shaped and U-shaped abnormal morphology. In the prolapse group, there were 5 cases with normal vaginal morphology and 43 cases with abnormal morphologymainly including U-shaped (13 cases), W-shaped (26 cases) and O-shaped(4 cases) abnormal morphology. There was significant difference between the two groups(c2=46.137,P<0.01). The area under the curve (AUC) was 0.800. The sensitivity and specificity of abnormal vaginal shape for diagnosing pelvic organ prolapse were 89.6% and 78.4%respectively.The distribution of vaginal morphology in different degrees and types of prolapse were different:vaginal morphology of 0 stage prolapse showed H-typed mainly (40/51, 78.4%), Ⅰ stage prolapse showed W-shaped (16/28 57.1%), Ⅱ,Ⅲ stage prolapse all showed non H-shaped (20/20, 100%), Ⅱstage mainly showed W-shaped (9/14), Ⅲ stage mainly showed O-shaped (3/6). Anterior pelvic organ prolapse were manifested mainly with W-shaped vaginal morphology (4/9) and middle pelvic organ prolapse mainly showed O-shaped vaginal morphology (4/7). Conclusions The abnormal vaginal morphology has the prompt value on diagnosing pelvic organ prolapse.Moreover, the different shape probably indicates the different degrees and types of pelvic organ prolapse.

OBJECTIVE To investigate the intervention effect and potential mechanism of breviscapine on hepatic fibrosis (HF) in rats based on the transforming growth factor-β(1 TGF-β1)/Smad2/extracellular signal-regulated protein kinase 1(ERK1) and Kelch-like epichlorohydrin-associated protein 1(Keap1)/nuclear factor-erythroid 2-related factor 2(Nrf2)/heme oxygenase-1(HO-1) pathways. METHODS Totally 60 rats were randomly divided into normal control group, model group, breviscapine low-dose, medium-dose and high-dose groups (5.4, 10.8, 21.6 mg/kg), and colchicine group (positive control, 0.45 mg/kg), with 10 rats in each group, half male and half female. Except for the normal control group, HF model of the other groups was induced by carbon tetrachloride. Subsequently, each drug group was given corresponding medicine by gavage once a day for 28 days. The liver appearance of rats in each group was observed and their liver coefficients were calculated. The levels of alanineaminotransferase (ALT) and aspartate aminotransferase (AST)in serum, those of ALT, AST, superoxide dismutase (SOD),malondialdehyde (MDA) and glutathione peroxidase (GSH- Px) in liver tissue were detected. The liver tissue inflammatory and fibrotic changes were observed. The protein and mRNA expressions of TGF-β1, Smad2, ERK1, Nrf2, Keap1 and HO-in liver tissue were detected. RESULTS Compared with the normal control group, the model group showed large areas of white nodular lesions in the liver, obvious inflammatory cell infiltration and collagen fiber deposition. The body weight, the levels of SOD and GSH-Px in liver tissue, the protein and mRNA expressions of Nrf2 and HO-1 were significantly lowered in the model group (P<0.05); the liver coefficient, the percentage of Masson staining positive area, ALT and AST levels of serum and liver tissue, MDA level of liver tissue, the protein and mRNA expressions of TGF-β1, Smad2, ERK1 and Keap1 were significantly increased (P<0.05). Compared with the model group, the liver lesions of rats in each drug group were improved, and the above quantitative indexes were generally reversed (P<0.05). CONCLUSIONS Breviscapine has a good intervention effect on HF rats, which may be related to inhibiting TGF-β1/Smad2/ERK1 pathway for anti-fibrosis and regulating Keap1/Nrf2/HO-1 pathway to inhibit oxidative stress.
