KIF4A Promotes Clear Cell Renal Cell Carcinoma (ccRCC) Proliferation in vitro and in vivo.

Purpose: To evaluate the expression in human clear cell renal cell carcinoma (ccRCC) tissues and explore the effects of kinesin family member 4A (KIF4A) on ccRCC progression.

Methods: GEPIA was used to evaluate the mRNA levels of KIF4A in human ccRCC tissues from TCGA database, and Immunohistochemistry (IHC) assays were performed to assess its expression in human ccRCC tissues collected in our hospital. The clinical-pathological analysis was performed to explore the correlation with KIF4A expression.

Efficacy and safety of dapoxetine for premature ejaculation: an updated systematic review and meta-analysis.

We conducted a systematic review and meta-analysis of published randomised controlled trials of dapoxetine for premature ejaculation. We systematically searched Embase, PubMed, Cochrane, Web of Knowledge, FDA.gov and Clinical Trials.

[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.

[Safety and effect of transurethral holmium laser enucleation of the prostate versus bipolar transurethral plasmakinetic prostatectomy for benign prostatic hyperplasia: A meta-analysis].

Objective: To evaluate the safety and effect of transurethral holmium laser enucleation of the prostate (HoLEP) in comparison with bipolar transurethral plasmakinetic prostatectomy (TUPKP) in the treatment of benign prostatic hyperplasia (BPH).

Methods: We searched the databases of PubMed, SCI, Ovid, The Cochrane Library, CNKI, CBM, VIP, and Wangfang Data for controlled clinical trials about HoLEP versus TUPKP in the treatment of BPH published up to April 2016. The studies were screened according to the inclusion and exclusion criteria, the data extracted, and their quality evaluated by 2 reviewers independently, followed by a meta-analysis using the RevMan 5.

[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.

A potential skin substitute constructed with hEGF gene modified HaCaT cells for treatment of burn wounds in a rat model.

This study aimed to investigate the feasibility of using an immortal keratinocyte cell line, HaCaT cells, to effectively deliver epidermal growth factor (EGF) in a skin substitute to treat burn wounds. The skin equivalent was constructed with human EGF (hEGF) gene modified HaCaT cells obtained through stable gene transfection; these were applied to full thickness burn wounds in a rat model. The results showed that the hEGF gene modified HaCaT cells produced more than 390ng/l of bioactive hEGF in the culture supernatant.

[Biological effects of paracrine from insulin stimulated adipose-derived stem cells (ADSC) on human vascular endothelial cells].

Objective: To study the biological effects of the paracrine from ADSC after being stimulated by insulin on vascular endothelial cells.

Methods: (1) ADSC was isolated from human adipose tissue and cultured in vitro. The third generation cells were collected and divided into insulin group (I, cultured with serum-free DMEM containing 1 x 10(-7) mol/L insulin) and control group (C, cultured with serum-free DMEM) according to the random number table, with 6 slots in each group.

Smad interacting protein 1 as a regulator of skin fibrosis in pathological scars.

Keloids and hypertrophic scars are significant symptomatic clinical problems characterized by the excessive and abnormal deposition of collagen-based extracellular matrix (ECM) components. However, the molecular basis of keloid and hypertrophic scar formation has not been fully elucidated. Here, we demonstrated that down-regulation of the transcription factor Smad interacting protein 1 (SIP1) could be relevant to keloid and hypertrophic scar formation.

[Tea polyphenols protects the testis following testicular torsion/detorsion in rats].

Objective: To investigate the protective effect of tea polyphenols against testis injury induced by unilateral testicular torsion/detorsion.

Methods: Twenty-four healthy male Wistar rats were equally randomized into Group I, sham operation, and Groups II and III, subjected to left lateral 720 degrees testicular torsion, followed by detorsion at 6 hours. Intraperitoneal injection of isotonic saline and polyphenols was initiated 30 minutes prior to detorsion and maintained at a low dose for 3 days postoperatively.
