Objective To study the role of interleukin-6(IL-6)in the pathogenesis of prostate cancer and its clinical significance. Methods Immunohistochemistry and RT-PCR were used to detect the expression of IL-6 protein and mRNA in frozen prostatic adenocarcinoma,adjacent benign prostatic tissue,and prostate cancer cell lines PC-3 and LNCaP. The serum levels of IL-6 in patients with prostate cancer and healthy controls,and the supernatants of prostate cancer cell cultures were measured by using ELISA. Results The IL-6 protein levels in prostate cancer tissue and PC-3 cells were significantly higher than those in adjacent benign prostatic tissue and LNCaP cells. The serum IL-6 levels in the patients with prostate cancer were markedly higher than those in the healthy controls. The IL-6 levels in supernatants in PC-3 cells were notably higher than those in the LNCaP cells. Conclusion The IL-6 gene may act as an important regulator in prostate cancer progression and may be one of the causes of prostate cancer conversion from an initially androgen-dependent state into an androgen-independent state.

This study examined the differences in tumor formation of three bladder tumor cell lines (BIU-87, T24 and EJ) after subcutaneously transplanted into nude mice, in order to find the best technique for establishing in vivo bladder tumor model. BIU-87, T24 and EJ cells at logarithmic phase were re-suspended in serum-free medium. The cells suspensions of the identical concentration were subcutaneously transplanted into nude mice and then the success rate and tumor growth were compared among the three cell groups. The results of tumor formation were pathologically evaluated. Lung, liver and kidney tissues were also pathologically examined for distant metastasis. The proliferation of the three cells were determined by immunohistochemically detecting the PCNA expression in the tumors. The results showed that the success rates of EJ and T24 cells were significantly higher than that of BIU-87 cells and no distant metastasis was noted among the three groups. The proliferation levels of EJ and T24 cells was significantly higher than that of BIU-87. But at the later stage of tumor formation, as compared with T24 cells, EJ grew more vigorously, soon resulting in the central necrosis of tumor, which affected the measurement of the actual size of the tumors. Moreover, PCNA staining exhibited that the proliferation of EJ and T24 was significantly higher than that of BIU-87 cells. It is concluded that as compared with BIU-87 cells, EJ and T24 cells had higher success rates, with not significant differences in death rate and distant metastasis found among them. There existed no significant difference in tumor formation between EJ and T24 cells and T24 cells do not rupture easily, which makes it a better cell line for the establishment of in vivo bladder tumor model.

Objective To summarize the experience of management of upper urinary tract calculi by Extracorporeal Shock Wave Lithotripsy (ESWL) in our department in order to improve the gravel success rate and decrease the incidence of complications.Methods 15 019 patients with upper urinary calculi from October 1988 to September 2011 treated by ESWL with X-ray localization were analyzed retrospectively.The maximum diameter of the stones ranged from 0.8 cm to 3.2 cm,with 1 3 794 cases with maximum stone diameter less than 2 cm (guoup A),and with 1225 cases with maximum stone diameter more than 2 cm (guoup B).All patients had normal or nearly normal renal function,and 56.0％ patients (8 410/15 019)had varying degrees of hydronephrosis.Results The effective rate of first ESWL was 84.5％ ( 12 691/15 019) and the effective rate of second ESWL was 12.0％ (1 802/15 019),and 313 cases need a third ESWL.The clearance rate in group A was 90.2％ ( 12 443/13 794 ),in group B was 50.9％ (623/1225),and the overall stone clearance rate within three months was 87.0％ ( 13 066/15 019).The majority of patients ( about 93％ ) had postoperative gross hematuria,which disappeared after drinking lots of water.46cases (0.3％) of patients had postoperative fever,which returned to normal after usage of antibiotics.There were no serious complications such as kidney hematoma,continuous high fever,continuous hematuria,ureteral stones jams.Conclusions ESWL.with X-ray localization had the advantage of low energy,minor injury,easy localization,uniform stone fragment,because of which it could reduce the complications such as continuity fever,ureter stone james,continuious hematuria.ESWL with X-ray localization could be preferred treatment for upper urinary calculi with diameters between 10 to 20 mm.

The association between the single nucleotide polymorphisms (SNPs) in -174G/C and -634C/G of interleukin-6 (IL-6) promoter region and prostate cancer was examined in the population of Han people in Hubei region. TaqMan PCR was employed for the gene-typing of -174G/C and -634C/G in promoter region of IL-6 gene to compare the prostate cancer patients and normal controls in terms of genotype frequency, allele frequency and risk of prostate cancer. Enzyme-linked immunosorbent assay (ELISA) was used for the detection of IL-6 concentration in peripheral blood of the patients with prostate cancer and the relationship between the IL-6 level and the genotype was studied. Our results showed that in all the subjects, the genotype of genetic locus -174G/C was found to be GG and no CG and CC were observed. There was a significant difference in gene frequency of GG, CG and CC of -634C/G and allele frequency of G and C between prostate cancer patients and normal controls (P<0.05) and the gene frequency of GG+CG increased with the clinical stages and pathological grades of prostate cancer. The IL-6 level in GG+CG group was significantly higher than that in CC group. It was concluded that no SNP in -174G/C IL-6 promoter region was found in the population of Han people in Hubei region. The SNP in -634C/G was, to some extent, associated with the development and progression of prostate cancer. The population with GG+CG genetype has higher risk for prostate cancer.

This study examined the effect of silencing LRIG3 expression on the proliferation and apoptosis of bladder cancer T24 cells and explored the role of LRIG3 in the tumorigenesis of bladder cancer. Bladder cancer T24 cells were routinely cultured and pSilencer plasmids were employed to construct LRIG3 eukaryotic expression vector of LRIG3-siRNA, i.e., pSilencer-LRIG3-siRNA. After confirmation, the vector was transfected into HEK293 cells to make a replication-deficient adenovirus, pAd-LRIG3-siRNA, which was then introduced into bladder cancer T24 cells. RT-PCR, Western-blotting were performed to detect the levels of LRIG3 mRNA and proteins. Cells number was determined by using MTT test. Hoechst33258 staining, transmission microscopy, flow cytometery were conducted to examine the cell apoptosis. Three groups included a blank control group, a negative control group (containing non-interfering plasmids) and a pAd-LRIG3-siRNA group. Our results showed that the recombinant pAd-LRIG3-siRNA was successfully transfected into the bladder cancer T24 cells. The siRNA formed by the transcription of the recombinant plasmids resulted in significantly reduced expressions of LRIG3 gene and protein and significantly decreased cell proliferation and growth in the pAd-LRIG3-siRNA group as compared with the control group (P<0.01). The siRNA also caused apoptotic changes of some cells, with the apoptosis rate being (17.69±0.75)%, which was significantly different from that of the control group (P<0.01). It was concluded that recombinant pAd-LRIG3-siRNA plasmids could effectively decrease the expression of LRIG3 mRNA and proteins and, to some extent, inhibit the proliferation and promote the apoptosis of bladder cancer T24 cells. Silencing LRIG3 gene might be a novel alternative for the treatment of bladder cancer.

In order to study the pathogenesis, clinical and pathological characteristics of proliferative lesions of the bladder, 50 cases of proliferative lesions of the bladder from 150 patients with complaints of frequency, urgency, hematuria and dysuria were subjected to cystoscopic biopsy of the suspicious foci in the bladder. In combination with the symptoms, urine and urodynamics, the relationship of proliferative lesions of the bladder to the inflammation and obstruction of the lower urinary tract was analyzed. Of the 50 cases of proliferative bladder lesions, 44 cases (88%) had lower urinary tract infection and 29 (58%) lower urinary tract obstruction. The patients with lower urinary tract obstruction were all complicated with infection. Three cases were associated with transitional cell carcinoma. Malignant cells were detected in 1 case by urinary cytologic examination. Proliferative lesions of the bladder, especially those without other obvious mucosa changes under cystoscopy, are common histological variants of urothelium in the patients with chronic inflammation and obstruction of the lower urinary tract. Chronic inflammation and obstruction of the lower urinary tract might be the causes for proliferative lesions of the bladder. It is suggested that different treatments should be applied according to the scope and histological type of the proliferative lesions.

Objective To investigate the clinical and pathological features of sacral nerve root lesions and the diagnosis and treatment for these clinical entities.Methods The clinical data of the patients with urine retention or refractory lower urinary tract symptoms (LUTS) caused by sacral nerve root lesions were retrospectively analyzed.Totally 27 patients were included in this study,including 4 cases of acute retention,6 chronic retention and 17 refractory LUTS.All patients had urodynamic disorders and sacral nerve root space-occupying lesions demonstrated by magnetic resonance imaging.All the patients received surgical treatment and were followed up one year or more.Results The pathological findings included simple cyst in 3 cases,ganglioneuroma in 5,cyst wall inflammation in 15,cyst wall hyaline degeneration in 15,and neurodegeneration in 15.Postoperatively,9 of the 10 patients with retention could voluntarily void and 1 remained suprapubic catheter drainage.All 17 patients with refractory LUTS improved significantly in terms of international prostate symptom score,visual analogue scale pain score,quality of life,maximal urinary flow rate and post void residual (P＜0.01).Conclusions Sacral nerve root lesions can be the causes of urinary retention or refractory LUTS.Surgical treatment can improve patient's voiding function and quality of life.

BACKGROUND: Interleukin-1 (IL-1β) and intercellular adhesion molecule-1 (ICAM-1 ) can mediate neutrophilic infiltration, which is closely relevant to cerebral ischemia-reperfusion injury.OBJECTIVE: To investigate the effect of physcion on cerebral inflammatory reaction after ischemia-reperfusion injury.DESIGN: A completely randomized study based on animals.SETTING: Neurological department in a university hospital.MATERIALS: From September to December 2003, the study was conducted in the Animal Laboratory, Hebei Staff and Workers Medical College. Totally 91 healthy male SD rats, supplied by Laboratory Animal Center of Hebei Medical University, were used in the experiments. They were divided into sham operation (SO) group, ischemia-reperfusion group, normal control group, 20 mg/kg physcion group and 40 mg/kg physcion group.Each of the former two groups would be divided into 4 subgroups named as the 6th-hour-after-reperfusion group, the 12th-hour-after-reperfusion group, the 24th-hour-after-reperfusion group and the 48th-hour-after-reperfusion group. Each of the latter two groups were divided into 2 subgroups named as the 12thhour-after-reperfusion group and the 24th-hour-after-reperfusion group. Each subgroup contained 7 rats.INTERVENTIONS: Middle cerebral artery occlusion model (MCAO model) was applied, and IL-1β was measured by radioimmunoassay and ICAM-1 was detected by immunohistochemical staining.MAIN OUTCOME MEASUREMENTS: The IL-1 β level and the positive expression of ICAM-1 in the rats' cerebella were observed.RESULTS: Cerebral ischemia-reperfusion injury in the rats reached its peak 6 hours after reperfusion, and then it decreased gradually. In the 12-hour-after-reperfusion subgroup amd the 24-hour-after-reperfusion subgroup of the 40 mg/kg physcion group, and the 12-hour-after-reperfusion subgroup of the 20 mg/kg physcion group, IL-1β in the injured parts of the cerebella decreased dramatically, compared with MCAO model controls ( P＜ 0.01 ). In the normal control group and SO group, a small quantity of ICAM-1 was detected in rat' s cerebral cortex, and some fulvous staining substance was observed in the plasma and membrane of cerebral vascular endothelium cells. In the cerebral ischemia-reperfusion injury group, positive staining substance could be observed 24 hours after the reperfusion, then darkened gradually (integral absorbency value: 31.89 ± 4.38, area density value: 0. 018 5 ± 0. 003 1). In the 12-hour-after-reperfusion subgroup of the 40 mg/kg physcion group (integral absorbency value: 13.33 ±6. 12, area density value: 0. 007 6 ± 0. 002 2) and the 24-hour-after-reperfusion subgroup of the 40 mg/kg physcion group (integral absorbency value: 20.04 ±4.65,area density value: 0. 012 9 ±0. 003 6), and in the 24-hour-after-reperfusion subgroup of the 20 mg/kg physcion group (integral absorbency value:23.73 ±4.51 area density value: 0. 014 1 ±0. 003 8), expressions of ICAM-1 around the infarctions significantly decreased as compared with those in the MCAO model controls respectively ( P ＜ 0.01 or P ＜ 0.05).CONCLUSION: Physcion tends to decrease the expressing of IL-1β and ICAM-1 in a cerebellum after ischemia-reperfusion injury, thus, it may help alleviate the ischemia-reperfusion injury.

AIM: To explore the effect of physcion (P) on the level of IL-1? and expression of ICAM-1 and caspase-3 during cerebral ischemia-reperfusion injury. METHODS: The 91 healthy adult SD rats were selected, and were randomly divided into normal group, sham-operated group, cerebral ischemia-reperfusion group (model), low-dose physcion (PLD) and high-dose physcion (PHD) treatment group. The level of IL-1? was detected by radioimmunoassay. The expression of ICAM-1 and caspase-3 was detected by immunohistochemistry. The changes of tissue pathology were also investigated. RESULTS: The level of IL-1? reached the peak at 6 h after ischemia-reperfusion (IR). The protein expression of ICAM-1 and caspase-3 reached the peak at 24 h after IR. The level of IL-1? and the protein expression of ICAM-1 and caspase-3 in PHD group decreased obviously compared with those in model group (P
