A New Process of Preparing Rice Straw-Reinforced LLDPE Composite.

To reduce the pollution resulting from discarding waste plastic film and burning straw, a new method of preparing straw-reinforced LLDPE composites was developed to utilize these wastes. The straws were first laid parallel on an LLDPE film and then rolled up. The rolls containing long straws were laid into a mat and then hot-pressed into a long straw composite board (the mass of straw accounted for 60%).

The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011.

Methods: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers.

Performance of Straw/Linear Low Density Polyethylene Composite Prepared with Film-Roll Hot Pressing.

Thermoplastic composites are usually prepared with the extrusion method, and straw reinforcement material must be processed to fiber or powder. In this study, film-roll hot pressing was developed to reinforce linear low density polyethylene (LLDPE) with long continuous straw stems. The long straw stems were wrapped with LLDPE film and then hot pressed and cooled to prepare straw/LLDPE composite.

Comprehensive genomic variation profiling of cervical intraepithelial neoplasia and cervical cancer identifies potential targets for cervical cancer early warning.

Methods: We performed whole-genome sequencing or whole-exome sequencing of 102 tumour-normal pairs and human papillomavirus probe capture sequencing of 45 CCs, 44 CIN samples and 25 normal cervical samples, and constructed strict integrated workflow of genomic analysis.

Results: Mutational analysis identified eight significantly mutated genes in CC including four genes (, , and ), which have not previously been reported in CC.

Evaluation of the bioactivity about anti-sca-1/basic fibroblast growth factor-urinary bladder matrix scaffold for pelvic reconstruction.

Unlabelled: Introduction and hypothesis: Pelvic support structure injury is the major cause of pelvic organ prolapse. At present, polypropylene-based filler material has been suggested as a common method to treat pelvic organ prolapse. However, it cannot functionally rehabilitate the pelvic support structure.

Androgen/androgen receptor axis maintains and promotes cancer cell stemness through direct activation of Nanog transcription in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common and malignant cancers. The HCC incidence gets a strong sexual dimorphism as men are the major sufferers in this disaster. Although several studies have uncovered the presentative correlation between the axis of androgen/androgen receptor (AR) and HCC incidence, the mechanism is still largely unknown.

High levels of circulating CD34+/VEGFR3+ lymphatic/vascular endothelial progenitor cells is correlated with lymph node metastasis in patients with epithelial ovarian cancer.

Aim: Lymph node metastasis is one of the predictive factors associated with poor prognosis of epithelial ovarian cancer. To clarify the role of CD34 and vascular endothelial growth factor receptor-3-positive (CD34+/VEGFR3+) lymphatic/vascular endothelial progenitor cells (LVEPC) in patients with lymph node metastasis and epithelial ovarian cancer progression, the levels of circulating CD34+/VEGFR3+ LVEPC in epithelial ovarian cancer patients were detected. We also tested the plasma protein levels of VEGF and stromal cell-derived factor to find out their possible relationships with lymph node metastasis in our epithelial ovarian cancer cohort.

Histological response to and immunogenicity of different material patches implanted in rabbit abdominal walls.

The high failure rate of traditional procedures of repairing pelvic organ prolapse by using sutures pushes multiple transvaginal mesh delivery systems into the marketplace; however, these are currently without optimal clinical results. We observed the short-term histological changes and the effects of Th1/Th2 cytokines after the implantation in rabbit abdominal walls of five materials, i.e.

The data of operating time, blood loss, numbers of lymph node, the length of resected vaginal and paracervix tissue were collected and compared.

Laparoscopic resection of presacral teratomas.

Presacral and retrorectal space tumors are relatively rare lesions, the location of which can result in the onset of symptoms that are not well-defined. Retrorectal teratomas are resected to alleviate these symptoms and to rule out malignancy. Complete resection by one of the open abdominal or sacral approaches was traditionally advocated as the best treatment for either a benign or malignant presacral and retrorectal tumor.
