[Efficacy of combination therapy of tamsulosin and solifenacin for mild and moderate benign prostatic hyperplasia with overactive bladder].

Objective: To evaluate the efficacy and safety of the combination therapy of tamsulosin and solifenacin for mild and moderate benign prostatic hyperplasia (BPH) with overactive bladder (OAB).

Methods: We randomly divided 166 patients with BPH and concomitant OAB into a mild obstruction symptom group (n = 88) and a moderate obstruction symptom group (n =78), 48 of the former group treated with 0. 2 mg tamsulosin + 5 mg solifenacin and the other 40 with 0.

Multiple renal arteries with renal cell carcinoma: preoperative evaluation using computed tomography angiography prior to laparoscopic nephrectomy.

Objective: To investigate anatomical variations in the renal arteries of patients with renal cell carcinoma (RCC) using computed tomography angiography (CTA).

Methods: Patients diagnosed with RCC were evaluated using CTA prior to undergoing laparoscopic nephrectomy. Any anatomical variations of the renal arteries on the side affected by the RCC were recorded.

Cucurbit[5]uril-metal complex-induced room-temperature phosphorescence of α-naphthol and β-naphthol.

Similar to the larger members of the cucurbituril family, such as cucurbit[8]uril (Q[8]), the smallest member, cucurbit[5]uril (Q[5]), can also induce room-temperature phosphorescence (RTP) of α-naphthol (1) and β-naphthol (2). The relationship between the RTP intensity of 1 and 2 and the concentration of Q[5] or Q[8] suggests that the mechanism underlying the Q[5] complex-induced RTP is different from that of the Q[8]-induced RTP for these luminophores. The crystal structures of 1-Q[5]-KI, 2-Q[5]-KI, 1-Q[5]-TlNO(3), and 2-Q[5]-TlNO(3) systems show that in each case Q[5] and the respective metal ions, K(+) or Tl(+), form infinite ···Q[5]-M(+)-Q[5]-M(+)··· chains that surround the luminophores.

Relationship between PTEN and Livin expression and malignancy of renal cell carcinomas.

Objectives: This study focused on PTEN and Livin expression and associations with malignancy in human renal clear cell carcinomas (RCCC).

Methods: PTEN and Livin expression was assessed in 100 RCCC tissue samples, 50 paracarcinoma cases, and 20 normal renal tissue samples using the immunohistochemical Streptavidin proxidase (SP) method. The relationships between binding and corresponding biological characteristics, such as histological grade, lymph node metastases, and clinical stages were analyzed.

[Cucurbit[8]urils-induced room temperature phosphorescence of phenanthrene and fluorene].

In this paper, a new room temperature phosphorescence for phenanthrene and fluorene were first reported with cucurbit[8]uril as the revulsant, KI as the heavy atomperturber, and Na2SO3 as deoxygenation. The RTP maximum wavelengths were lambda(ex)/lambda(em) = 282/509 nm and lambda(ex)/lambda(em) = 276/518 nm and the RTP lifetimes of the two systems were 1.82 and 3.

[Sexual function of men with symptomatic benign prostatic hyperplasia and effect of Tamsulosin].

Objective: To study the sexual function of men with benign prostatic hyperplasia (BPH) with the lower urinary tract symptoms (LUTS) and the effect of Tamsulosin.

Methods: One hundred and ninety-two cases of BPH accompanied with typical LUTS were investigated using the International Prostate Symptom Score (IPSS), Quality of Life (QOL), International Index of Erectile Function 5 (IIEF-5) and measuring the flow rate of urine before treatment. The patients were randomly divided into two groups, the treatment group (n = 103) given Tamsulosin 0.

[Changes of serum total PSA and free PSA in patients with prostate carcinoma and benign prostate hyperplasia].

Background & Objective: Total prostate-specific antigen (TPSA) is considered the best marker in diagnosis of carcinoma of prostate (Pca), and FPSA (free prostate specific antigen)/TPSA can improve its specificity in diagnosis of PCa. This study was designed to compare the level of serum TPSA and FPSA/TPSA between PCa and benign prostate hyperplasia (BPH) patients, providing reference for diagnosis of PCa.

Methods: Values of serum TPSA and FPSA of 66 BPH cases, 29 BPH with acute urinary retention (AUR) cases, 22 PCa cases were determined by enzyme linked immunosorbent assay (ELISA).

[Age-specific reference ranges for serum prostate-specific antigen in Chinese men].

Objective: To evaluate the age-specific reference ranges for serum prostate-specific antigen in Chinese men.

Methods: Serum tPSA and fPSA were measured by enzyme-linked immunosorbent assay (ELISA) and fPSA/tPSA ratio was calculated in 1,096 health Chinese men of 23 - 85 years old. The relationship between age and PSA indexes was analyzed with simple linear regression.
