OBJECTIVEThe research tended to approach applying of adjustable appliance in the treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS).
METHODS30 OSAHS patients (24 males and 6 females) participated in the adjustable group, with a mean age of (49.9 +/- 9.9) years old. AHI was (33.1 +/- 22.7) per hour. The control group consisted of 30 OSAHS patients wearing ordinary mandibular advancing appliance in the corresponding period, with age, weight and AHI at the same level. Monoblind way was designed to obtain and analyze the therapy differences. Differences in changes of upper airway, mandible and hyoid bone were also analyzed among the doctor-experience position, final adjusted position and original position.
RESULTSAHI decreased by 85.5% in the adjustable appliance group. The change in AHI was greater significantly (P = 0.025) in the adjustable group than in the control group. In the final adjusted position, the amount of mandibular advancement was (5.8 +/- 1.4) mm [(71 +/- 26)% of the maximum range of protrusion] and that of bite opening (the distance between upper and lower incisor edges) was (4.6 +/- 1.1) mm.
CONCLUSIONSThe adjustable appliance had shown better therapy effect in OSAHS patients. The final adjusted position provided useful information on determining mandibular position using other appliances.

OBJECTIVETo evaluate the toxic effects of the CD-TK fusion gene systems against prostate carcinoma cell line RM-1 for assessing the value of suicidal gene therapy for prostate carcinoma.
METHODSCD-TK fusion gene and green fluorescent protein (GFP) gene were transfected into RM-1 cells through adenovirus vectors. RT-PCR was used to demonstrate successful transfection and transcription of the suicidal genes. The toxic effects of 5-FC and GCV used alone or in combination on the transfected cells were observed by MTT assay, with the non-transfected RM-1 cells serving as control.
RESULTSCytotoxic activity of CD/5-FC and TK/GCV systems against RM-1 cells was observed, and combined treatment with the two drugs resulted in significantly lowered survival of CD-TK-expressing cells (P<0.05). After exposure to 5-FC and GCV for 72 h, the survival rate of the transfected cells decreased to 71.56% and 47.27%, respectively, and their combined use resulted in a survival rate as low as 18.46%.
CONCLUSIONCD-TK fusion double suicidal gene system can produce significantly stronger toxic effect against RM-1 cells in vitro than either of suicidal genes.

OBJECTIVETo investigate the cell-killing effect of adenovirus-mediated TK-ganciclovir (GCV) gene therapy in combination with tumor necrosis factor-alpha (TNF-alpha) against murine bladder carcinoma cells in vitro.
METHODSMurine bladder carcinoma MB49 cells were transfected with the adenoviral vector containing TK gene and green fluorescent protein (GFP) gene. The transfection efficiency was observed and the TK gene expression in the transfected cells was detected by RT-PCR. The survival rate of MB49 cells in response to TNF-alpha treatment and that of the TK gene-transfected cells after treatment with GCV and GCV+TNF-alpha were determined by MTT assay. The apoptosis of the cells after the treatments was analyzed by flow cytometry.
RESULTSIn cells transfected with TK gene, the cell inhibition rate increased gradually with the increment of GCV and TNF-alpha concentration. GCV in combination with TNF-alpha resulted in significantly increased killing efficiency of the cells as compared with GCV or TNF-alpha treatment alone, and the effect of the combined treatment was enhanced as the TNF-alpha concentration increased. GCV treatment (50 microg/ml) alone produced a cell killing rate of (24.39-/+1.10)%, and when combined with 5 microg/ml TNF-alpha, the rate was increased to (40.05-/+0.97) %, and further to (65.47-/+0.67) % when TNF-alpha concentration increased to 20 microg/ml. Flow cytometry revealed obvious apoptosis of the cells 8 h after treatments with TK/GCV, TNF-alpha, or TK/GCV+TNF-alpha, and the combined treatment resulted in the highest cell apoptotic rate.
CONCLUSIONTK/GCV in combination with TNF-alpha can enhance the effect of suicide gene therapy against murine bladder carcinoma cells and effectively induce apoptosis of the cells.

OBJECTIVETo investigate a novel immunotherapy through immobilization of streptavidin-tagged hTNF-alpha on the biotinylated mucosal surface of the bladder wall for bladder cancer treatment in mice.
METHODSA total of 120 female C57BL/6j mice were randomized into 5 equal groups, namely blank control, PBS, soluble hTNF-alpha, SA-GFP, and SA-hTNF-alpha treatment groups. Twenty-four hours after establishment of a mouse model of orthotopic superficial bladder cancer, SA-hTNF-alpha fusion protein was immobilized on the biotinylated mucosal surface of the bladder wall, which was repeated every 4 days for a total of 6 sessions. Immunohistochemistry was performed to detect the retention time of SA-hTNF-alpha fusion protein in the biotinylated mouse bladder mucosa and the distribution of CD4(+) and CD8(+) lymphocytes in the mucosa and tumor tissues, with the tumor growth and mouse survival also observed. The cytotoxiciy of the tumor-specific lymphocytes was evaluated. The mice responding well to the treatment were re-challenged by MB49 and monitored for survival.
RESULTSSA-hTNF-alpha could be efficiently and stably immobilized on the bladder mucosal surface for as long as 7 days. On day 60 after MB49 implantation, 18 out of 22 SA- hTNF-alpha-treated mice survived, with 9 appearing tumor-free, but all the mice in PBS control group died. Five out of 9 tumor-free mice in SA-hTNF-alpha group showed resistance to a re-challenge with intravesical MB49. The numbers of CD4(+) and CD8(+) lymphocytes were significantly greater in SA-hTNF-alpha group than in the other groups (P<0.05). The cytotoxicity of the tumor-specific lymphocytes was significantly stronger in SA-hTNF-alpha group than in the other groups (P<0.05).
CONCLUSIONSA-hTNF-alpha immobilized on the biotinylated mucosal surface of the bladder wall can significantly inhibit the tumor growth and promote the survival of the mice bearing orthotopic superficial bladder cancer.

OBJECTIVETo investigate the effects of transurethral catheterization on the uroflow rate in the pressure-flow study of patients with benign prostatic hyperplasia (BPH).
METHODSThirty-nine men with BPH underwent free uroflowmetry and pressure-flow analysis respectively. With an 8 F urethral catheter, the standard pressure-flow variables such as the maximum flow rate, detrusor pressure at the maximum flow rate and so on were recorded. The free maximum flow rate and the maximum flow rate with transurethral catheterization were statistically analyzed.
RESULTSThe maximum voided volumes of the free uroflowmetry group and the pressure-flow study group were (209.23 +/- 56. 56) ml and (210.33 +/- 62.02) ml respectively (P > 0.05). The free maximum flow rate was (8.61 +/- 2.80) ml/s, and the maximum flow rate with transurethral catheterization-was (7.39 +/- 3.01) ml/s (P < 0.05). When the patients were divided into seven grades of bladder outlet obstruction (BOO) according to the Schäfer nomogram, the free maximum flow rate and the maximum flow rate with transurethral catheterization with Grade 0-I of BOO were (12.56 +/- 1.57) ml/s and (10.95 +/- 2.51) ml/s, and those of Grade II were (9.35 +/- 0.76) ml/s and (8.41 +/- 1.23) ml/s respectively. For Grades III, IV and V-VI , the two maximum flow rates were (7.88 +/- 1.21) ml/s and (6.37 +/- 0.59) ml/s, (6.54 +/- 1.93) ml/s and (5.55 +/- 2.48) ml/s, and (6.01 +/- 2.10) ml/s and (4.84 +/- 2.89) ml/s, respectively, all with significant difference in between (P < 0.05).
CONCLUSIONThe 8 F urethral catheter has a significant effect on the maximum uroflow rate in the pressure-flow study and this effect is correlated with the grade of BOO.

OBJECTIVETo establish a simple and efficient method for establishing a mouse model of orthotopic superficial bladder cancer.
METHODSC57BL/6 mice were anesthetized with sodium pentobarbital and catheterized with modified IV catheter (24 G). The mice were intravesically pretreated with HCl and then with NaOH, and after washing the bladders with phosphate-buffered saline (PBS), 100 microl (1 x 10(7)) MB49 cells were infused and allowed to incubate in the bladder for 2 h followed intravesical mitomycin C (MMC) administration. The tumor formation rate, survival, gross hematuria, and bladder weight were determined as the outcome variables, and the pathology of the bladders was observed.
RESULTSInstillation of MB49 tumor cells resulted in a tumor formation rates of 100% in all the pretreated groups while 0% in the control group without pretreatment. MMC significantly reduced the bladder weight as compared to PBS.
CONCLUSIONWe have successfully established a stable, reproducible, and reliable orthotopic bladder cancer model in mice.

OBJECTIVETo compare efficacy between the modified tension band technique and the parallel titanium cannulated lag screw technique for the transverse patella fracture.
METHODSSeventy-two patients were retrospectively analyzed aged 22 to 79 years (mean, 55.6 years) with transverse patella fractures, among whom 37 patients underwent the modified tension band and 35 patients received the titanium cannulated lag screw. Patients were followed up for 1-3 years. We analyzed the difference of operation time, complications, fracture reduction, fracture healing time, and the Iowa score for knee function between both groups.
RESULTSIn modified tension band group, five patients had skin irritation and seven suffered wire migration, two of whom required a second operation. In comparison, there were no complications in the titanium cannulated lag screw group, which also had a higher fracture reduction rate and less operation time.
CONCLUSIONThe parallel titanium cannulated lag screw technique has superior results and should be considered as an alternative method to treat transverse patella fracture.

OBJECTIVETo report our data of patients with clinical stage T(1-3)N(1-2)M(0) renal cell carcinoma (RCC) and explore the biological behavior of this malignancy.
METHODSA total of 531 patients with no distant metastatic RCC underwent open radical nephrectomy at our institution between 1988 and 2008, among whom 42 patients with histological nodal metastases had successful surgical tumor resection. The clinical data and outcomes of the 42 patients were analyzed.
RESULTSOf those 42 patients, 19.0% had T1, 21.4% had T2, and 59.5% had T3 stage tumors; 42.9% had N1 and 57.1% had N2 stage tumors. Tumor recurred in 30 (71.4%) patients after the surgery, and death occurred in 26 (61.9%) cases at the last follow-up; among the recurrent cases, 83.3% (25/30) had multiple metastases at the initial recurrence. The median cancer-specific survival (CSS) and disease-free survival (DFS) was 23 and 11 months in these cases, respectively. Multivariate analysis demonstrated that Fuhrman grade (P=0.005), N stage (P=0.014) and T stage (P=0.037) were the independent predictors of CSS; Eastern Cooperative Oncology Group (ECOG) performance status (PS) (P=0.002), tumor size (P=0.007), Fuhrman grade (P=0.009) and N stage (P=0.019) were the independent predictors of DFS.
CONCLUSIONPatients with T(1-3)N(1-2)M(0) RCC have poor prognosis. N stage is an independent predictor of both CSS and DFS, suggesting that extended lymph node dissection should be performed when suspicious enlarged nodal disease is found during surgery.
