Association of leptin, visfatin, apelin, resistin and adiponectin with clear cell renal cell carcinoma.

Although an association between obesity and the occurrence of renal cell carcinoma (RCC) has been identified, the mechanism by which obesity functions to increase this risk of cancer remains unclear. Leptin, visfatin, apelin, resistin and adiponectin are peptide hormones secreted by adipocytes; it is considered that these may affect RCC development by exerting effects on proliferation, cell growth and inflammation. The aim of the present study was to investigate the association between the aforementioned adipokine genes and clear cell RCC (CC-RCC).

High-resolution Melting PCR Analysis for Genotyping Lys109Arg and Gln223Arg in Patients with Renal Cell Carcinoma.

Although several studies have documented the role of leptin receptor gene polymorphisms in cancers, the association between leptin receptor gene polymorphisms and renal cell carcinoma (RCC) remains unknown. The aim of this study was to develop a high-resolution melting (HRM) approach for genotyping single nucleotide polymorphisms of leptin receptor gene on the LightCycler 480, and to explore the relation between polymorphisms of the leptin receptor gene and RCC. The study population consisted of 83 patients with renal cell carcinoma and 161 healthy control subjects.

[Efficacy and safety of Saw Palmetto Extract Capsules in the treatment of benign prostatic hyperplasia].

Objective: To assess the efficacy and safety of Saw Palmetto Extract Capsules in the treatment of benign prostatic hyperplasia (BPH).

Methods: We conducted a multi-centered open clinical study on 165 BPH patients treated with Saw Palmetto Extract Capsules at a dose of 160 mg qd for 12 weeks. At the baseline and after 6 and 12 weeks of medication, we compared the International Prostate Symptom Scores (IPSS), prostate volume, postvoid residual urine volume, urinary flow rate, quality of life scores (QOL), and adverse events between the two groups of patients.

Association of leptin receptor Lys109Arg and Gln223Arg polymorphisms with increased risk of clear cell renal cell carcinoma.

Background: Although roles of genetic polymorphisms of leptin receptor (LEPR) gene in several cancers have been documented, the association between polymorphisms of LEPR and clear cell renal cell carcinoma (CC-RCC) remains unknown. The aim of this study was to explore any relation.

Materials And Methods: The study population consisted of 77 patients with CC-RCC and 161 healthy control subjects.

[EPCA-2 in the early diagnosis of prostate cancer].

More and more clinical evidence has confirmed the limitations of the use of serum PSA in the screening, detection and treatment of prostate cancer, and scientists are continuously seeking for new biomarkers of the disease. The discovery of early prostate cancer antigen 2 (EPCA-2) has provided a new base for the screening, detection, treatment and follow-up of prostate cancer.

The expression and clinical significance of TGF-beta1 and MMP2 in human renal clear cell carcinoma.

The expression and clinical significance of transforming growth factor beta1 (TGF-beta1) and matrix metalloproteinase-2 (MMP2) in human renal clear cell carcinoma (RCCC) were investigated. The intensity of TGF-beta1 and MMP2 expression in RCCC kidneys was significantly higher than that in normal kidneys. Expression of TGF-beta1 and MMP2 in RCCC tissues was positively correlated with pathological grade and clinical stage.

[Effects of selective cyclooxygenase-2 inhibitor on proliferation and apoptosis of human bladder cancer cell line T24].

Background & Objective: Cyclooxygenase-2 (COX-2) is related closely to the tumorigenesis of bladder cancer, and COX-2 inhibitor has potential antitumor effect. This study was to investigate the effects of selective COX-2 inhibitors on the proliferation and apoptosis of human bladder cancer cell line T24.

Methods: The effects of selective COX-2 inhibitors SC-58125 and celecoxib, and nonselective COX inhibitor indomethacin on the proliferation of T24 cells were evaluated by MTT assay.
