Testis cell pyroptosis mediated by CASP1 and CASP4: possible sertoli cell-only syndrome pathogenesis.

Background: Sertoli cell-only syndrome (SCOS) is the most serious pathological type of non-obstructive azoospermia. Recently, several genes related to SCOS have been identified, including FANCM, TEX14, NR5A1, NANOS2, PLK4, WNK3, and FANCA, but they cannot fully explain the pathogenesis of SCOS. This study attempted to explain spermatogenesis dysfunction in SCOS through testicular tissue RNA sequencing and to provide new targets for SCOS diagnosis and therapy.

Obstructive sleep apnea is related to alterations in fecal microbiome and impaired intestinal barrier function.

Obstructive Sleep Apnea (OSA) is related to repeated upper airway collapse, intermittent hypoxia, and intestinal barrier dysfunction. The resulting damage to the intestinal barrier may affect or be affected by the intestinal microbiota. A prospective case-control was used, including 48 subjects from Sleep Medicine Center of Nanfang Hospital.

Prognostic Significance and Diagnostic Value of Overexpressed lncRNA PVT1 in Colorectal Cancer.

Background: The aim of this study is to investigate the expression of lncRNA PVT1 in CRC tissue compared to adjacent normal tissues, and reveal the association between lncRNA PVT1 expression level and the clinicopathological characteristics of patients with CRC.

Methods: We detected the lncRNA PVT1 relative expression of cancerous tissues in 130 patients with CRC by using real-time quantitative polymerase chain reaction. At the same time, we collected the clinicopathological and prognostic information.

Increased Expression of PCNA-AS1 in Colorectal Cancer and its Clinical Association.

Background: The aim is to study the expression of PCNA-AS1 in colorectal cancer (CRC) tissue and paired-adjacent normal tissue and the relationship between its expression level and clinical pathological features.

Methods: Using real-time qPCR, PCNA-AS1 expression levels were detected in 114 cases to establish the relationship between its expression and clinicopathologic features. Moreover, the expressions of PCNA-AS1 were investigated in CRC and normal colonic epithelial cell lines.

Long Noncoding RNA PVT1 as a Potent Predictor of Prognosis in Cancers: a Meta-Analysis.

Background: Plasmacytoma variant translocation 1 (PVT1), an oncogenic long noncoding RNA located in a recognized cancer-risk gene region-8q24, is significantly overexpressed in various cancers. Many studies have found that high expression of PVT1 was correlated with poor prognosis.

Methods: This meta-analysis was performed by searching electronic databases Pubmed, Web of Science, Chinese National Knowledge Infrastructure, WanFang, and ChongQing VIP for eligible papers on the prognostic impact and clinicopathological characteristics of PVT1 expression in cancer from inception to January 31, 2017.

A prospective comparison of short term results and functional recovery after laparoscopic subtotal colectomy and antiperistaltic cecorectal anastomosis with short colonic reservoir vs. long colonic reservoir.

Background: To observe and compare the short term results and functional recovery of laparoscopic subtotal colectomy with antiperistaltic cecorectal anastomosis (LSCACRA) in the treatment of Adult slow transit constipation (STC) with two different reservoir length: short colonic reservoir and long colonic reservoir.

Methods: All STC patients treated with LSCACRA between April 2007 and December 2011 at our institution were followed up. Patients with 2 cm to 3 cm ascending colon preserved above the ileocecal junction were designated as observation group, whereas those preserved by 10 cm to 15 cm were classified as control group.
