Objective To study reliability and validity of incontinence impact questionnaire short form (IIQ-7) in the Chinese population. Methods IIQ-7 form was translated into Chinese; 74 patients with urinary incontinence completed the IIQ-7 simplified Chinese version and short-form 12-item health survey (SF-12) questionnaires. The urinary incontinence patient also ran a 1 hour pad test. Then, reliability and validity of those forms were analyzed. Results The Cronbach's alpha of IIQ-7 simplified Chinese version was 0. 824 (P <0. 01). The intra-class correlation coefficient of IIQ-7 simplified Chinese version was 0. 749 (P < 0.01) . IIQ-7 simplified Chinese version scores were negatively correlated with SF-12 scores (Spearman correlation coefficient: - 0. 570, P < 0. 01) , IIQ-7 simplified Chinese version scores were positively correlated with 1 hour pad test (Spearman correlation coefficient: 0.461, P < 0. 01) , IIQ-7 simplified Chinese version scores were also positively correlated with the course of disease (Spearman correlation coefficient: 0. 235 , P < 0. 05) . Factor analysis of IIQ-7 simplified Chinese version showed good construct validity. Conclusions The simplified Chinese version of IIQ-7 has higher reliability and validity in the Chinese population. They are highly recommended for clinical treatment and research.

Objective To study the arterial stiffness in non-diabetic pre-dialysis chronic kidney disease (CKD) patients and to explore the associated factors. Methods Automatic pulse wave velocity (PWV) measuring system was used to examine carotid-femoral pulse wave velocity (CFPWV) as the parameters reflecting central elastic large arterial elasticity. Vascular calcification was quantitatively evaluated by plain radiographic film of abdomen, pelvis and hands. Blood pressure, biochemical parameters and intact parathyroid hormone (iPTH) were routinely detected. Stepwise multiple linear regression analysis was used to assess the associated factors of arterial stiffness. Results Ninety-six non-diabetic pre-dialysis CKD patients and 30 healthy people were enrolled in this trial. CFPWV in stage 3, 4 and 5 CKD patients was significantly higher than that in healthy controls [(11.63±2.39) m/s, (11.70±2.80) m/s, (12.88±2.49) m/s vs (9.70±1.66)m/s , all P<0.05]. Stepwise multiple regression analysis demonstrated that age, mean arterial pressure, vascular calcification and iPTH were independent impact factors of CFPWV. Conclusions Arterial stiffness of large artery increases in non-diabetic pre-dialysis CKD patients. Age, mean arterial pressure, vascular calcification and iPTH are independent impact factors of CFPWV.

Objective To explore the clinical effect of color Doppler ultrasound guided small incision in repairing penile fracture.Methods Sixteen cases of penile fracture single cavernosum rupture adopted the preoperative positioning by color Doppler ultrasound,hematoma removal and albuginea repair.The clinical effect was evaluated after operation.Results The albuginea rupture was smoothly found in 15 cases,1 case was converted to coronary sulcus annular degloving incision.The operation time was 20-60 min with a mean of 35 min;the postoperative hospital stay was 3.0-6.0 d with a mean of 4.8 d;the catheter removal was on postoperative 3-5 d,urination was unobstructed.Follow up lasted for 6-12 months,1 case appeared transient erectile dysfunction,the harden was touched during erection in 1 case,and other cases had no obvious complication occurrence.Conclusion The color Doppler ultrasound can locate the rupture of corpora cavernosa penis and albuginea.Selecting color Doppler ultrasound guided small incision in repairing penile fracture has small trauma and less complications,and can get satisfactory effect.

OBJECTIVETo explore the effect and molecular mechanism of the unconventional prefoldin RPB5 interactor (URI) in hepatocellular carcinoma HepG2 cells.

METHODSThe cDNA sequence and shRNA of URI were obtained and sub-cloned into eukaryotic expression vectors. Then those vectors were transfected into HepG2 cells to obtain stable transfection cell line. The cell proliferation and anchor-independent growth in URI-overexpressing and knockdown HepG2 cells were determined by CCK-8 and soft agar colony assay. Flow cytometry was applied to detect the cell cycle and apoptosis of γ-ray irradiated cells. Apoptosis related genes were detected by Western blot.

RESULTSThe pCDNA3.1-URI and pGPU6-URIi eukaryotic expression vectors were constructed successfully and corresponding stable transfection cell lines were obtained. Cell proliferation rates of the HepG2, pCDNA3.1-URI-HepG2 and pGPU6-URIi-HepG2 cells were (588.78 ± 32.12)%, (959.33 ± 58.8)% and (393.93 ± 39.7)%, respectively (P < 0.05). The number of cell clones of HepG2, pCDNA3.1-URI-HepG2 and pGPU6-URIi-HepG2 cells were 43 ± 7, 85 ± 5 and 20 ± 4 (P < 0.05), respectively. After γ-ray irradiation, the URI-overexpressing cell line showed a significantly lower apoptosis rate and G(2)/M phase arrest than those in the URI-depleted cell line (P < 0.05). In the HepG2 cells, the relative protein expression levels of URI, Bax and Bcl-2 were 0.92 ± 0.03, 1.11 ± 0.13 and 0.82 ± 0.01 (P < 0.05). In the pCDNA3.1-URI-HepG2 cells, the relative protein expression levels of URI, Bax and Bcl-2 were 1.79 ± 0.12, 0.48 ± 0.01 and 2.20 ± 0.30 (P < 0.05), respectively. In the pGPU6-URIi-HepG2 cells, the relative protein expression levels of URI, Bax and Bcl-2 were 0.50 ± 0.04, 1.52 ± 0.20 and 0.38 ± 0.01 (P < 0.05), respectively. The expression of Bax was down-regulated and Bcl-2 was up-regulated in the URI-overexpressing cell line. However, on the contrary, expression of Bax was up-regulated and Bcl-2 was down-regulated in the URI-depleted cell line.

CONCLUSIONSURI may promote the growth of hepatocellular carcinoma cells via inhibition of cell proliferation and reducing the apoptosis in hepatocellular carcinoma cells in vitro. After the impairment of URI expression, the proliferation ability of hepatocellular carcinoma cells is suppressed and the ability to resist γ-ray irradiation is reduced. URI may become a potential new target for cancer therapy of hepatocellular carcinoma.
