BACKGROUND: Our aims in the present study were to estimate the influences of pain and urinary symptoms on quality of life, and to determine which of these two variables has the most predictive power with respect to quality of life in young men with chronic prostatitis-like symptoms. METHODS: Chronic prostatitis-like symptoms were measured by the National Institutes of Health-Chronic Prostatitis Symptom Index. Of the 28,841 men aged 20 years who lived in the study community, 18,495 men (a response rate 64.1%) agreed to participate in the study. A total of 1057 men who complained of symptoms indicative of chronic prostatitis were included in the study. The influences of pain and urinary symptoms on quality of life were determined using logistic regression analysis. The receiver operating characteristic (ROC) curve was used to estimate the predictive ability of each of these variables with respect to quality of life. RESULTS: Results from multivariate analysis showed that both pain and urinary symptoms were associated with an increased likelihood of impaired quality of life, although pain contributed more to a reduced quality of life than urinary symptoms. Relative to men who experienced mild pain, men who experienced moderate pain had a 3.9-fold risk of poor quality of life (odds ratio [OR], 3.87; 95% confidence interval [CI], 2.86-5.23; P < 0.001) and those who experienced severe pain had a 15.7-fold risk of reduced quality of life (OR, 15.68; 95% CI, 6.59-37.35; P < 0.001). Moderate urinary symptoms were associated with a 1.4-fold risk of bother (OR, 1.41; 95% CI, 1.01-1.99; P < 0.001) and severe urinary symptoms were associated with 2.4-fold risk (OR, 2.39; 95% CI, 1.37-4.12; P < 0.001), relative to mild urinary symptoms. Comparison of the effects of pain and urinary symptoms showed that pain severity had the most predictive power for bother, quality of life, and quality-of-life impact. The areas under the ROC curves for bother, quality of life, and quality-of-life impact were 71.3%, 69.3% and 72.5%, respectively. CONCLUSION: Urinary symptoms and pain might be associated with an increased likelihood of impaired quality of life in young men with chronic prostatitis-like symptoms. In addition, our findings suggest that pain severity is the most influential variable for determining quality of life in this population. 相似文献

BACKGROUND: Insulin-like growth factor binding protein-2 (IGFBP-2) is expressed by all human prostate cancer cell lines and dramatically increases in the serum of prostate cancer patients. However, the role of IGFBP-2 in prostatic tumorigenesis is not known. The aim of the present study was to investigate the effects of IGFBP-2 on the proliferation of DU145 human prostate cancer cells in culture. METHODS: Using cell proliferation assays, we examined the effects of exogenously administered and endogenously modulated levels of IGFBP-2 on the proliferation of DU145 cells. RESULT: Cell growth was stimulated by exogenously administered IGFBP-2, but significantly retarded (P < 0.05) by its neutralizing antibody. Overexpression of IGFBP-2 by transfection also stimulated cell growth, which was significantly (P < 0.05) inhibited in transfectants expressing antisense mRNA to IGFBP-2. Furthermore, the proliferation of IGFBP-2 overexpressing cells was significantly dampened by exogenously administered IGFBP-2 antibody. CONCLUSIONS: IGFBP-2 is an autocrine growth factor for DU145 human prostate cancer cells and cell proliferation can be significantly retarded by neutralizing or inhibiting its synthesis. These findings provide a strong rationale for targeting IGFBP-2 in the testing of novel strategies to treat prostate cancer. 相似文献

WHAN KOOK CHUNG KYU YONG CHOI CHANG DON LEE JIN WU CHUNG HEE SIK SUN KYU WON CHUNG BOO SUNG KIM CHUNG SIK CHUN KYOO HONG CHO SEUNG JO KIM 《Journal of gastroenterology and hepatology》1987,2(1):13-17
Different doses of hepatitis B virus vaccine—prepared by Korea Green Cross Corporation, were given to healthy infants born to HBsAg-negative mothers at birth, 1 and 6 months of age. A dose of 2 μg was administered intradermally in Group A and, in the three other groups, the vaccine was given intramuscularly (i.m.). An adequate follow-up observation was possible for 9 months after birth in 22, 25, 23 and 21 infants in Groups A, B, C and D, respecvely.
Group C (5 μg, i.m.) produced seroconversion most rapidly, showing the highest rate (96%) at 9 months of age. The lowest seroconversion rate (5%) was found at the age of 1 month in Group A subjects, but the rate increased to 91% after a booster dose was given at 6 months of age.
While it can be concluded that a 5 μg i.m. dose of vaccine at 0, 1 and 6 months of age is optimum for the immunization of infants in efficacy and economy, a 2 μg intradermal dose can also be considered as an immunogenic and economical regimen, though the immune response is slower and a special technique is required for immunization. 相似文献

Signal transduction pathway in human middle ear cholesteatoma 总被引:5,自引:0,他引:5
KEEHYUN PARK MD YOUNG-MYOUNG CHUN MD DONG-HOON LEE MD SUNG CHUL HWANG MD 《Otolaryngology--head and neck surgery》1999,120(6):899-904
Phospholipase C-gamma1 plays a central role in signal transduction, and it is important in cellular growth, differentiation, and proliferation. Human cholesteatoma in the middle ear is characterized by the presence of a keratinizing epithelium that is believed to have hyperproliferative properties. The purpose of this study is to elucidate the distribution of phospholipase C-gamma1 in cholesteatoma matrix and deep meatal skin with Western blot analysis and immunohistochemistry. In conclusion, overexpression of phospholipase C-gamma1 in cholesteatoma matrix suggests a possible derangement of enhanced growth signal transduction in keratinocytes. 相似文献

Laparoscopic radical cystectomy with extracorporeal urinary diversion: Preliminary experience 总被引:2,自引:0,他引:2
SUNG-HOO HONG SEONG-IL SEO JOON CHUL KIM TAE-KON HWANG 《International journal of urology》2005,12(10):869-874
AIM: We present our experience with the fi rst eight patients who underwent laparoscopic radical cystectomy with bilateral pelvic lymphadenectomy and extracorporeal urinary diversion. Patients, operative data and the surgical techniques are presented. METHODS: Between June 2003 and April 2004, seven men and one woman with organ-con fi ned muscle-invasive transitional cell carcinoma of the bladder underwent laparoscopic radical cystectomy with urinary diversion. The age range was 41-73 years. Laparoscopic radical cystectomy and bilateral pelvic lymphadenectomy were performed using fi ve ports by a transperitoneal approach. An ileal conduit diversion or ileal W-neobladder was constructed through the site of specimen retrieval. RESULTS: We performed eight radical cystectomies with ileal conduits (six cases) or orthotopic ileal W-neobladders (two cases). Conversion to open surgery was necessary in one due to technical dif fi culty in urethroneobladder anastomosis. Mean operating time was 560 min (range 455-680). Mean estimated blood loss was 675 mL (range 400-1050). Two of the eight patients needed blood transfusion (800 mL each). Mean days to oral intake and ambulation was 4.4 (range 2-6) and 4.1 (range 3-5), respectively. Mean hospital stay was 12.8 days (range 7-28). Mean follow up was 6.1 months (range 4-14). Histopathological examination of the specimens revealed stage T2N0M0 in fi ve cases, T3aN0M0 in one, T3aN1M0 in one and T3bN1M0 in one. No metastases have been detected and all are alive and free of disease. CONCLUSION: Laparoscopic radical cystectomy is feasible, although dif fi cult and technically demanding, and our results are promising. With more experience and improvement of the surgical technique, laparoscopic radical cystectomy with urinary diversion may become an alternative surgical method for treating the selected patients with localized muscle invasive bladder cancer. 相似文献
