Objective To discuss the clinical correlation between chronic prostatitis (CP) and erectile dysfunction (ED).Methods A retrospective analysis was made on the clinical data from patients who were diagnosed as CP in urology department of the First People's Hospital of Yunnan Province and the First Affiliated Hospital of Sun Yat-sen University.Patients' data were collected from July 2005 to July 2012.All the patients were diagnosed as CP based on their clinical manifestation,the NIH Chronic Prostatitis Symptom Index,prostatic fluid examination,routine urine examination and ultrasonography.The condition of erectile function was inquired on every patient and recorded.Results There were 4 315 patients diagnosed as CP in present study,while their age ranged from 17 to 64 years (average,31 years).Sixty-one (1.41％) patients were identified as moderate and severe types of ED (International Index of Erectile Function 5 ≤ 11),while 42 (0.97％) patients were confirmed as ED after they got CP.435/4 315 patients (10.08％)felt obviously sexuality descent after they got CP,and the sexuality was reported improved in 426/435 pa-tients after prostatitis symptomatic relief.Conclusions The incidence rate of ED in CP patients is not ob-viously higher than that in common community.And sexuality descent in patients might be caused by localindisposition and anxiety after CP.

Objecive:To estimate the predictable value of histopathologic parameters in chronic rhinosinusitis with nasal polyps(CRSwNP)after endoscopic sinus surgery(ESS). Method:Symptomatology was rated in 53 patients 12 to 24 months after ESS.Specimens taken during the surgical procedure were examined and scored for eosinophils.goblet cells,lymphocytes,subepithelial thickening,subepithelial edema and submucous gland formation. The correlation between histopathologic parameters and postoperative symptoms was then evaluated. Result:The most common symptome after ESS were nasal obsruction,nasal secretion,discharge and sneezing. The correlation between goblet cells and sneezing,discharge,submueous gland formation and headache,subepithelial edema and postnasal secretion was significant(P＜0.05). Conclusion:Certain histopathologic parameters in CRSwNP are predictive of favorable response to ESS.

Objective: To provide an important tool for the study of diagnose and treatment of prostate cancer (PCa) osseous metastasis and change of bone stress force on prostate cancer (PCa) osseous metastasis and a platform, which is more congruous to clinical process, for prevention and cure of neoplastic bone metastases, and to carry out the construction and improvement of animal models of PCa with different positional osseous metastasis in vivo.Methods: Different gradient concentrations of RM-1 cells were inoculated into the cavity of left femoral bone or lumbar vertebra of mice (C57BL/6) respectively.The change of mouse activity, tumor formation, tumor size and survival time were observed respectively.And the femur tissue and spinal tissue were obtained from the mice after death.The gray value of iconography were measured by imageological examination of femur tissue, and the final histopathological examination were taken to determine the tumor type in both femur and spinal tissue.Results: The tumor growth could be touched at the puncture site in all the mice after inoculated for 7 days.There were no obvious differences in the time of tumorigenesis, the rate of tumor growth and tumor size among the mice in the same group (P>0.05).As the result, the construction femoral bone and lumbar vertebra metastatic models of PCa had been confirmed by iconography and pathology detection.At the same time, the survival time of the mice inoculated with low concentrations of PCa cells was obviously longer than that of high concentrations of PCa cells (at least 2 weeks longer).Conclusion: The animal models with different positional osseous metastasis (limbs and axial skeleton) of PCa using the same PCa cells (RM-1) had been first constructed successfully in our study.At the same time, a high success rate of construction of PCa animal model with bone metastasis was obtained by femoral bone marrow cavity injection of PCa cells.The rate of tumor growth was rapid, animal survival time was appropriate, and the PCa animal model with bone metastasis can be stably reproduced by our method.These animal models can be used to explore the pathogenesis of different positional PCa bone metastasis and provide a new platform, which were more congruous to clinical process, for prevention and cure of neoplastic bone metastases.

Objective To screen and identify the novel markers for renal cell carcinoma. Methods The renal cancer A498 cell line was used as the antigen and human normal renal cell line HK-2 was used as control for subtraction biopanning from a phage display peptide library at 37 ℃ The positive and specific binding clones were identified by cell-based ELISA and immunocytochemical staining, and the identified clones were sequenced. Thus the amino acid sequence was deduced and the peptide was synthesized. The peptide was identified by immunofluorescence. Results Through a cell-based ELISA, immunocytochemical staining, and immunofluorescence, the Phage ZT-2 and synthetic peptide ZT-2 were shown to specially bind to the A498. The affinity binding to A498 was the highest (A_(ZT-2)/A_(control) = 3. 15) among the peptides assayed. The optical density of ZT-2 in renal cancer tissue (0. 453±0. 123) was significantly higher than that in normal and inflammatory renal tissue (0. 148±0. 075)(P<0. 01). Conclusions A peptide ZT-2 which is specific binding to renal cancer cell line A498 had been selected from phage display peptide libraries. Therefore, it provides a potential tool for early diagnosis of renal cancer or targeted drug delivery in chemotherapy.

ObjectiveTo explore the expression of novel protein kinase C ε (PKCε) in normal prostate (NP) tissue, benign prostate hyperplasia(BPH), peficancerous (PC) tissue and prostate cancer (Pca), and study its correlation with the grade and stage of Pca.MethodsTen NP slides, ten BPH slides, ten PC slides and 43 Pca slides were collected from our hospital. These slides were routinely proceased and analyzed according to the requirement of immunohistochemical staining. Tumors were classified according to the 2002 TNM staging system. The grading system used in the study was based on the Gleason grade.ResultsWe was found that the expression of PKCεs in Pca (27/43) were significantly higher than those in NP(1/10), BPH (0/10) and PC (2/10) tissue, and the difference was statistically significant ( P ＜0.05 ). With regard to grade of prostate cancer, the expression of PKCε in Pca with Gleason score ≥8 group (12/13) was higher than the Gleason score 2 -4 group (4/10) and the Gleason score 5 -7 group (11/20). The difference was statistically significant (P ＜ 0.05 ). Moreover, the T3 and T4 stages had a more positive rate (10/12 & 9/10) than the T1 and T2 stages( 1/6 &7/15). There is statistically significant difference between early and advanced stage of prostate cancer ( P ＜ 0. 05 ). Furthermore, the positive expression of PKCε in prostatic carcinoma samples increased significantly in the metastasis group (9/10)compared to the non-metastasis group ( 18/33 ) ( P ＜ 0. 05 ), but the difference was not statistically significant between the concentration of prostate-specific antigen in blood serum ( P ＞ 0. 05 ).Conclusions PKCε is expressed in prostate cancer, and it correlates with the grade and stage of prostate cancer. PKCε may be related to the origin and the development of Pca, and it may be used as a prognostic factor for Pca.

METHOD: Symptomatology was rated in 53 patients 12 to 24 months after ESS. Specimens taken during the surgical procedure were examined and scored for eosinophils, goblet cells, lymphocytes, subepithelial thickening, subepithelial edema and submucous gland formation. The correlation between histopathologic parameters and postoperative symptoms was then evaluated. RESULT: The most common symptome after ESS were nasal obsruction, nasal secretion, discharge and sneezing. The correlation between goblet cells and sneezing, discharge, submucous gland formation and headache, subepithelial edema and postnasal secretion was significant (P < 0.05). CONCLUSION Certain histopathologic parameters in CRSwNP are predictive of favorable response to ESS.
