Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue. Early penile rehabilitation after surgery can improve or restore the erectile function of the patients. This article focuses on penile rehabilitation after radical pelvic surgery.

Aim To investigate the protective effects of polysaccharides from the rhizomorph of Armillaria mella(AMP-1) on alloxan injured INS-1 cells.Methods Graded concentrations of AMP-1(2,10,50,100,500,1 000 mg?L-1) were added into the culture medium of alloxan injured INS-1 cells.The survival rate was measured by MTT assay.The amount of glucose-stimulated insulin secretion in different concentrations of AMP-1 was determined by radioimmunoassay(RIA).SOD and NOS activity,NO,MDA and GSH production were assayed colorimetrically.Results AMP-1 could reduce oxidative injuries induced by alloxan in INS-1 cells.The survival rate of cells treated with AMP-1 increased significantly.In the presence of 5.6 mmol?L-1 or 16.7 mmol?L-1 glucose,AMP-1(50,100,500,1 000 mg?L-1)increased glucose-induced insulin secretion in INS-1 cells in a dose-dependent manner.NOS levels and the production of NO and MDA decreased significantly by AMP-1,while SOD levels and the production of GSH increased.Conclusions AMP-1 promoted glucose-induced insulin secretion in INS-1 cells by increasing the abilities of scavenging the free radicals induced by alloxan.

Purpose:To clarify the different expression patterns of the cyclins and P21 between the normal breast epithelium cells and breast cancer cells of different degrees of malignancy.Methods:Using Western Blot, we detected the protein expression of cyclin D1, E, and p21 in the normal breast epithelium cells AG11132A, ER positive MCF 7 breast cancer cells and ER negative MDA MB 231 breast cancer cells.Results:(1) P21 protein was highly expressed and cyclin E lowly expressed in the normal breast epithelium cells. Compared with the normal breast epithelium cells, Cyclin E were highly expressed in breast cancer cells of MCF 7 and MDA MB 231 cells. Abnormal low molecular weight cyclin E was co expressed with normal cyclin E in both MCF 7 and MDA MB 231 breast cancer cells, but not in normal breast epithelium cells AG11132A. (2) In breast cancer cells, compared with the ER positive MCF 7 cells the ER negative MDA MB 231 cells expressed a high level of cyclin E protein but low p21.Conclusions:(1) There are many forms of differences both quantitive and qualitative between normal cells and cancer cells, as well as between relatively low degree and high degree invasive malignant cancer cells. (2) Cyclin E and P21 may be potential indicators that reflect the malignancy of breast cancer cells, but they should be analyzed as a whole in order to get more accurate prognostic information. [

Objective To investigate levels of IL-17 and IL-22 mRNA in the blood of type 2 diabetes(T2DM)patients with the different stages of kidney injury and explore the relationship between the gene expression levels of IL-17,IL-22 and renal lesions in patients with diabetic nephropathy(DM).Methods Subjects included 60 T2DM patients with or without kidney injury and 20 normal controls(NC,n=20).Diabetes patients were divided into 3 groups by level of urinary albumin to creati-nine ratio (ACR):no proteinuria group (NA,ACR<30 mg/g,n=22),microalb uminuria group (MA,30 mg/g>ACR>300 mg/g,n=18)and diabetic nephropathy group (DN,ACR>300 mg/g,n=20).Quantitative Real-Time RT-PCR was used to detect IL-17 and IL-22 mRNA levels.Analysis differences of IL-17 and IL-22 mRNA levels among NA,MA,DN and NC groups.Results The levels of IL-17 and IL-22 mRNA were significantly higher in DN group than that in MA,NA and NC group (P <0.01,respectively),However,there were not significant difference among MA,NA and NC group (P >0.05,re-spectively).Conclusion Levels IL-17 and IL-22 mRNA were increased in blood of T2DM patients with nephropathy.IL-17 and IL-22 may play role in the pathogenicity of diabetic nephropathy.

Conclusion: MR is measured in human embryo tissue, the se results provide experimental data for elucidating the mechanism of the effect of Mel.

Objective To explore the value of Gadofluorine M,a novel M RI enhancement agent,in the diagnosis the early radiation brain injury.Methods Seventy-two Wistar rats were randomly divided into 5 equal groups.To establish the radiation injury model,the rat's posterior brain was irradiated with 0(blank controls),25,35,45,55,and 65 Gy,respectively.After irradiation MR plain scanning and Gadofluorine M enhancement scanning (after the T1WI and T2WI scanning Gf at the dosage of 0.1 mmol/kg was injected intravenously and scanning was performed again 12 h later) were performed once a week for 8 weeks.Another 12 rats were randomly divided into 2 equal groups to exposure to 55 and 65Gy,respectively,and MR scanning was performed once a week for 8 weeks since the third week after MR.After T1WI and T2WI scanning Gd-DTPA was injected intravenously,MR was conducted again 30 min later,and Gf was injected intravenously (Gd-DTPAenhancement and Gf enhancement contrast).The MR image and the pixel count were compared.Since the third week 2 rats from the Gf enhancement scanning group and 1 rat from the Gd-DTPA enhancement and Gf enhancement contrast were killed after MR with their brains taken out to undergo pathological examination.Results No abnormal signal changes were found in MRI in 25 and 35 Gy groups within 2 months after irradiation.A high signal in the Gf enhancement T1 WI image was found in 45,55,and 65 Gy groups within the period of 4-6 weeks after radiation.The signal intensity was significantly higher than that of the control,25,and 35 Gy groups(F =2.15,P <0.05).The emerge time of this signal was negatively correlated with the dose of radiation(r =-0.62,P < 0.05).When there was no obvious change was found by Gd-DTPA enhancement,a high signal representing change of injury could be found in Gf enhancement in the same rat.The signal intensity was significantly enhanced in Gf enhancement compared to the Gd-DTPA enhancement (F = 2.74,P <0.01).Histopathology examination of the 65 Gy group showed frosted degeneration in part of the region,however,no obvious necrotic damage was found in other groups.Conclusions The Gf enhancement change appears before histopathological changes,it helps discover early radiation injury in brain.Compared to the regular MRI and Gd-DTPA enhancement,Gadofluorine M enhancement has obvious advantage and is worth further research and application.

Objective To evaluate CT findings, diagnosis and management of intrahepatic biliary injuries after transcatheter arterial chemoembolization (TACE) for liver malignancies. Methods A total of 1302 patients with hepatic malignant tumors received TACE between Sep 2007 and Mar 2009. None of these patients were found to have any radiographic evidence of biliary abnormalities before TACE. A retrospective review of imaging studies and clinical outcomes was carried out to evaluate the changes of intrahepatic biliary injuries after TACE. Results Six patients developed intrahepatic biliary injuries during 1 and 3-month follow-up. Two cases with jaundice and high fever, underwent percutaneous transhepatic cholangiography and drainage and eventually recovered. The other 4 patients were asymptomatic with only radiographic changes and were managed observationally. Conclusions Intrahepatic biliary injury is a rare complicating TACE procedures. It will be identified by clinical outcomes and radiographic imaging findings. Percutaneous transhepatic cholangiography and drainage (PTCD) is the therapy of choice for intrahepatic biliary injuries with jaundice or high fever.
