CDK13 promotes lipid deposition and prostate cancer progression by stimulating NSUN5-mediated m5C modification of ACC1 mRNA.

Cyclin-dependent kinases (CDKs) regulate cell cycle progression and the transcription of a number of genes, including lipid metabolism-related genes, and aberrant lipid metabolism is involved in prostate carcinogenesis. Previous studies have shown that CDK13 expression is upregulated and fatty acid synthesis is increased in prostate cancer (PCa). However, the molecular mechanisms linking CDK13 upregulation and aberrant lipid metabolism in PCa cells remain largely unknown.

Retroperitoneal laparoscopic adrenalectomy versus transperitoneal laparoscopic adrenalectomy for pheochromocytoma: a systematic review and meta-analysis.

Introduction: To compare the efficacy and safety of retroperitoneal laparoscopic adrenalectomy (RLA) vs. transperitoneal laparoscopic adrenalectomy (TLA) for pheochromocytoma (PHEO).

Aim: To perform a systematic review and meta-analysis to evaluate the efficacy and safety of RLA versus TLA for PHEO.

[Feasibility low cryptorchidism surgery following modified day surgical procedures].

Objective: To explore the feasibility and safety of cryptorchidism surgery in the day surgery center.

Methods: This retrospective study included 122 cases of unilateral low cryptorchidism (ULC) and 27 cases of bilateral low cryptorchidism (BLC) treated by orchidopexy from July 2018 to July 2022 in the Second Hospital of Hebei Medical University. We divided the patients with ULC into an Ad (day surgery following modified day surgical procedures) and an Ac (conventional surgery) group, and those with BLC into a Bd and a Bc group.

Effect of tadalafil combined with atorvastatin on hemodynamics and sexual function in middle-aged and elderly patients with hyperlipidemia complicated with erectile dysfunction.

Objective: To evaluate the effect and clinical significance of tadalafil combined with atorvastatin on hemodynamics and sexual function in middle-aged and elderly patients with hyperlipidemia complicated with Erectile dysfunction (ED).

Methods: Eighty patients with hyperlipidemia complicated with ED who were treated at The Second Hospital of Hebei Medical University from January 2019 to June 2020 were selected. Using a completely randomized design experimental method, these 80 patients were randomly divided into two groups: the experimental group and the control group, with 40 cases in each group.

Identification of a potentially functional circRNA-miRNA-mRNA ceRNA regulatory network in bladder cancer by analysis of microarray data.

Background: Circular RNAs (circRNAs) have received increasing attention in cancer development. However, a substantial number of circRNAs still require characterization. The purpose of this study is to uncover novel circRNAs and their molecular mechanism in bladder cancer (BCa).

miR-20b-5p, TGFBR2, and E2F1 Form a Regulatory Loop to Participate in Epithelial to Mesenchymal Transition in Prostate Cancer.

The transcription factor E2F1 regulates the expression of the miR-20b-5p precursor and is involved in epithelial-to-mesenchymal transition (EMT). Transforming growth factor-β1 (TGF-β1) induces EMT in prostate cancer (PCa) by binding to TGF-beta receptor 2 (TGFBR2) to activate TGF-β signaling. However, the relationship between TGFBR2, E2F1, and miR-20b-5p in the modulation of EMT in PCa cells remains unknown.

Cholinergic α5 nicotinic receptor is involved in the proliferation and invasion of human prostate cancer cells.

Nicotinic acetylcholine receptor (nAChR) subunit α5 (α5‑nAChR) is involved in tumor cell proliferation, inhibition of apoptosis, progression of metastasis, and induction of angiogenesis in certain solid tumors. However, the role of α5‑nAChR in prostate cancer cell growth and metastasis is unclear. In the present study, the role of α5‑nAChR in cell proliferation, migration, invasion and apoptosis was investigated by silencing the expression levels of α5‑nAChR in the prostate cancer cell lines DU145 and PC3.

[Transumbilical single-port laparoscopy combined with improved double hernia needles for pediatric hydrocele].

Objective: To compare the clinical effect of transumbilical single-port laparoscopy combined with improved double hernia needles with that of traditional open surgery in the treatment of hydrocele in children.

Methods: We retrospectively analyzed 35 cases (54 sides) of pediatric hydrocele treated by transumbilical single-port laparoscopy combined with improved double hernia needles (laparoscopy group). We recorded the operation time, intraoperative blood loss, hospital stay, scrotal edema, and postoperative complications and compared them with those of another 46 cases (58 sides) treated by traditional open surgery (open surgery group) during the same period.

Intervention effect and mechanism of curcumin in chronic urinary tract infection in rats.

Objective: To analyze the invention effect of curcumin on chronic urinary tract infection in rats and explore its possible mechanism of action.

Methods: The experimental animals were randomly divided into three groups, normal, model and curcumin group. Chronic urinary tract infection models were built for model group and curcumin group by injecting coliform fluid into the cavity of bladder.
