Robotic-assisted Laparoscopic Nephrectomy with Vein Thrombectomy: Initial Experience and Outcomes from a Single Surgeon.

This study was designed to explore the safety and feasibility of robotic-assisted laparoscopic nephrectomy with vein thrombectomy (RAL-NVT) for the treatment of renal cell carcinoma (RCC) with venous tumor thrombus (VTT). Clinical data of 6 patients treated with RAL-NVT between July 2016 and November 2017 in our hospital were retrospectively collected and analyzed. There were 5 males and 1 female with their age ranging from 48 years to 68 years.

[Impacts of Chk1 and Chk2 gene expressions on sperm concentration and motility].

Objective: To study the correlation of the gene expressions of Chk1 and Chk2 with sperm concentration and motility.

Methods: According to sperm concentration and motility (percentage of progressively motile sperm), we divided 80 semen samples into four groups of equal number: normal control, oligozoospermia (OS), asthenospermia (AS), and oligoasthenozoospermia (OAS). We detected the sperm DNA fragmentation index (DFI) and viability and determined the expressions of Chk1 and Chk2 in the sperm by RT-PCR and Western blot.

[Tea polyphenols reduces the apoptosis of spermatogenic cells in rats with experimental varicocele].

Objective: To study the effect of tea polyphenols (TP) on the apoptosis of germ cells in rats with experimental varicocele.

Methods: Thirty-two adolescent male Wistar rats were randomly and equally divided into groups A (sham-operation), B (high-dose TP), C (low-dose TP), and D (experimental left varicocele). Experimental varicocele was induced by partial ligation of the left renal vein in the latter three groups of rats.
