<b><i>Aims:</i></b> Early evaluation of pelvic floor muscle (PFM) in postpartum women is important for the treatment of stress urinary incontinence (SUI). Digital vaginal palpation and electromyography (EMG) evaluation based on Glazer protocol are widely used for the assessment of PFM. However, the correlation among digital palpation, EMG, and morbidity of postpartum SUI is still unclear. This study aims to investigate the relationship between postpartum SUI and PFM examinations. <b><i>Methods:</i></b> This hospital-based cross-sectional study included 1,380 parturients during September 2016 to January 2018. We collected the clinical characteristics, PFM strength, and EMG variables of parturients 6–8 weeks after birth. Then the correlation among the results of EMG, digital palpation, and the occurrence of SUI was analyzed. <b><i>Results:</i></b> There is no significant difference in digital palpation scores of PFM strength between SUI and non-SUI parturients. The EMG values were closely related to SUI: the multivariate logistic regression revealed that the most reliable evaluation indicators of postpartum SUI were pelvic floor contractile amplitude of endurance contraction (B = 0.021, <i>p</i> = 0.019) and pretest resting baseline (B = 0.056, <i>p</i> = 0.019). Correlation analysis demonstrated that the contraction variables of EMG had a significant correlation with the digital palpation PFM strength in postpartum women (<i>r</i> = 0.467–0.545, <i>p</i> &#x3c; 0.001). <b><i>Conclusion:</i></b> The EMG proved to be reliable in assessing the PFM function in postpartum women. The decreased PFM activity, according to EMG, was correlated with postpartum SUI. Although digital palpation scores were positively correlated with EMG results, no correlation was observed with SUI incidence.

Objectives. Postpartum pelvic floor muscle (PFM) injuries are the result of pregnancy and delivery, which lead to a series of symptoms requiring long-term follow-up. Mobile health platforms are progressively used for monitoring clinical conditions in medical subjects. This survey was a cross-sectional design based on collecting data from an application (Penyikang). We retrospectively analyzed the risk factors for weak postpartum PFM and further analyzed the factors influencing women’s participation in the treatment which may help to improve the app’s application in the future. Methods. We enrolled postpartum women who gave birth at the Women’s Hospital, Zhejiang University School of Medicine from August to November 2017; trained them to use the app; and collected the demographic and clinical information. This app requires users to fill questionnaires to assess their knowledge of pelvic floor dysfunction (PFD) and pelvic floor muscle training (PFMT) and experience with PFMT, and each therapy evaluation was restored. The relationship between the knowledge of PFMT/PFD, UI symptoms, and PFM strength was analyzed. Cluster analysis was used to define the degree of participation and identify the factors influencing the patients’ participation in intensive therapy and evaluation. Results. 1982 postpartum women who enrolled in the app program were defined as weak PFM. Younger maternal age, cesarean section, and without delivery injury were found as the prognostic factors to PFM strength (both type I and type II muscle fibers) (P<0.05), and higher educational level was also in favor of type II muscle fibers (P<0.05). Patient-reported UI symptoms were associated with weak PFM strength (P<0.05); there were no significant differences between knowledge of PFMT or PDF and PFM strength. Finally, patients with a higher degree of participation were more likely to accept the treatment (P<0.05). Conclusions. The mobile app provides a new applicative way to investigate postpartum PFD. The factors influencing women’s participation can help us focus on strategies to increase the patients’ compliance, and then we will apply the app into more areas to improve the prevention and treatment of postpartum PFD.

ObjectiveTo investigate the relationship between endoplasmic reticulum stress (ERS) and the pathogenesis of stress urinary incontinence (SUI) in postmenopausal women.MethodsAnterior vaginal wall tissue was collected from postmenopausal women with SUI and control subjects. Western blotting was performed for glucose-regulated protein (GRP78), inositol-requiring enzyme 1(IRE1), protein kinase-like endoplasmic reticulum kinase (PERK), activating transcription factor 6 (ATF6), C/EBP-homologous protein (CHOP), and B-cell lymphoma 2 (Bcl-2). Additionally, mRNA expression levels of PERK, activating transcription factor 4 (ATF4), and CHOP were examined by real-time polymerase chain reaction.ResultsGRP78 protein and mRNA expression levels were significantly lower in women with SUI, compared with control subjects. PERK and p-PERK expression levels were higher in women with SUI than in control subjects. However, no differences in IRE1 or ATF6 expression levels were observed in either group. Notably, higher CHOP and lower Bcl-2 protein expression levels were detected in women with SUI, compared with control subjects. Furthermore, PERK, ATF4, and CHOP mRNA expression levels were significantly higher in women with SUI than in control subjects.ConclusionsAlterations of ERS markers in SUI suggest that ERS may be involved in the development of SUI in postmenopausal women.

Objective: To introduce the minimally invasive Vecchietti procedure based on single-port laparoscopy with self-made surgical instruments for the surgical management of Mayer-Rokitansky-K€ uster-Hauser syndrome (MRKH). Design: Surgical video article. The approval of the Institutional Review Board and written consent from the patient were obtained. Setting: University hospital. Patient(s): A 22-year-old woman presented with primary amenorrhea and inability to participate in penetrative sexual intercourse. A gynecological examination revealed a phenotypically normal vulva and absence of the vagina. A normal 46,XX karyotype was expressed. Magnetic resonance imaging and ultrasonic imaging of the abdomen and pelvis indicated that the ovaries were normal in size and there was vaginal agenesis with rudimentary uterus. No other congenital malformations were present. Intervention(s): The modified Vecchietti procedure involved a transvaginal operation and laparoscopic surgery. The epidural catheter was stretched and made into two wires that were tucked into the core of the Veress needle and then folded into four strings for perineal puncture. A transverse incision of about 3 cm was made in the center of the navel, layer by layer into the abdomen, and placed in a selfmade single port (made of a small wound protector and an 8-inch glove), introducing the laparoscope. Under laparoscopic surveillance, the Veress needle was inserted through the vesicorectal space guided by the index finger, which was placed in the rectum. The epidural catheter was pumped from the core into the abdominal cavity under laparoscopy. Subsequently, cystoscopy was performed to ensure that no bladder perforation occurred during the needle insertion. The ball-shaped acrylic device and the two rubber stoppers were attached to the epidural catheter of the vulva. An epidural puncture needle with wire perforated the peritoneum through McBurney's point and the opposite McBurney's point, pulling the epidural catheter out of the abdominal cavity. The epidural catheter was curled around the gauze rolls until the ball-shaped device could be accommodated into the newly created cavity at a sufficient depth. After the surgery, the top of neovagina was lifted about 1 cm every day by tightening gauze rolls to increase the traction, until a neovagina 9 cm long was achieved. Main Outcome Measure(s): The clinical and anatomical data such as the operative time, intraoperative bleeding, duration of hospitalization, and measurement of the final length of the newly created canal 30 days after surgery and 3 months after surgery. Result(s): The operative time was 30 minutes, and the intraoperative blood loss was 10 mL. The duration of hospitalization was 10 days. Before discharge, the vaginal depth was 9 cm at 5 days after the surgery, and the self-made traction system was removed. A plastic mold was then inserted using povidone-iodine. The vaginal dilator had to be worn day and night. The patient was advised to sit at the corner of a hard bed or chair from time to time to enh...

Background: Exosomes are small Extracellular Vesicles (EVs) (40-100 nm) secreted by living cells and mediate the transmission of information between cells. The number and contents of exosomes are associated with diseases such as inflammatory diseases, cancer, metabolic diseases and what we are focusing in this passage-female infertility. Objective: This review focused on the role of exosomes in oocyte development, declined ovarian function, PCOS, uterine diseases, endometrial receptivity and fallopian tube dysfunction in the female. Methods: We conducted an extensive search for research articles involving relationships between exosomes and female infertility on the bibliographic database. Results: It has been reported that exosomes can act as a potential therapeutic device to carry cargoes to treat female infertility. However, the pathophysiological mechanisms of exosomes in female infertility have not been entirely elucidated. Further researches are needed to explore the etiology and provide evidence for potential clinical treatment. Conclusions: This review systematically summarized the role exosomes play in female infertility and its potential as drug delivery.
