RÉSUMÉ

OBJECTIVE: To investigate the preventive effect of rock salt aerosol on the development of silicosis in rats. METHODS: The specific pathogen free adult male SD rats were randomly divided into normal control group, rock salt control group, silicosis model group and rock salt intervention group, 18 rats in each group. Rats in the silicosis model group and the salt rock intervention group were treated with silica dust at the concentration of 2 000.0 mg/m~3 by dynamic dusting method for 3 hours daily. Rats in the rock salt control group and the rock salt intervention group inhaled the rock salt aerosols with the mass concentration of 20.0 mg/m~3 for 30 minutes daily. The normal control group was not treated with the dust or rock salt aerosol. At the time points of 14, 28 and 56 days after exposure to dust or rock salt aerosol, 6 rats were randomly selected from each group and samples were collected. The pathological change of lung was observed, the total cell count in the bronchoalveolar lavage fluid(BALF) was performed, the enzyme-linked immunosorbent assay was used to detect the change of transforming growth factor-β(TGF-β) in BALF, surfactant D(SP-D) and superoxide dismutase(SOD) in lung tissue. RESULTS: The results of hematoxylin-eosin and Masson staining showed that the inflammatory changes of lung tissue and the pulmonary interstitial fibrosis in the rock salt intervention group were less severer than that in the silicosis model group. At 14, 28, and 56 days after dust exposure, the total cell counts in BALF and SP-D levels in lung tissue of rats in silicosis model group and rock salt intervention group were higher(P<0.05), the SOD activities in lung tissue were lower(P<0.05), as well as the TGF-β levels in BALF in silicosis model group were higher(P<0.05),compared with the normal control group and rock salt control group. The total cell counts and TGF-β levels in BALF, and SP-D levels in lung tissue of rock salt intervention group were lower(P<0.05), the SOD activities in lung tissue were higher(P<0.05), compared with the silicosis model group. CONCLUSION: Rock salt aerosol intervention may delay the pathogenesis of silicosis by improving the inflammatory response, regulating oxidative stress and reducing interstitial fibrosis of lungs.

RÉSUMÉ

OBJECTIVE@#To investigate the effect of osthole on epidermal growth factor receptor tyrosine kinase (EGFR-TPK), matrix-metalloproteinase-2 (MMP-2), aminopeptidase N (APN) in bladder cancer cell and the underlying mechanism.
@*METHODS@#The T24 cell lines were cultured. The inhibitory effects of osthole on EGFR-TPK, APN and MMP-2 were evaluated by spectrophotometric and MTT assay. The caspase-3 activity and the expression COX-2 and VEGF in T24 were examined. The activity of NF-κB was determined by electrophoretic mobility shift assay.
@*RESULTS@#The half inhibition concentrations (IC50) of osthole on EGFR-TPK, APN and MMP-2 were (45.33±3.98), (28.21±3.23) and (8.11±0.54) µmol/L, respectively. The growth inhibitory rates for T24 cells were increased in a dose-dependent manner (P<0.05). The caspase-3 activities were significantly increased in T24 cells in the osthole group compared with control group, while the expression of angiogenesis related-protein COX-2, VEGF, and NF-κB in T24 cells were decreased.
@*CONCLUSION@#Through the inhibitory effect on EGFR-TPK, APN and MMP-2, osthole can decrease COX-2, VEGF and NF-κB expression while increase the activity of caspase-3, eventually blocking the growth and invasion of bladder cancer cell.

RÉSUMÉ

<p><b>BACKGROUND</b>Currently, cystoscopy and urine cytology are standard modalities in therapy monitoring and follow-up of bladder carcinoma (BC). Cystoscopy is an invasive and uncomfortable procedure while cytology has a limited value because it is operator-dependent and has low sensitivity. This study was to assess the accuracy of ImmunoCyt in detecting BC by comparing it with cytology using systemic analyses of studies published in both English and Chinese.</p><p><b>METHODS</b>Cochrane systematic evaluation was used to search through MEDLINE, EMBASE, Cochrane Library, CMCC, and CNKI for studies regarding ImmunoCyt and cytology for detection of BC. Data were extracted and analyzed by the software MetaDiSc 1.4.</p><p><b>RESULTS</b>In total 42 relevant studies were searched, of which 15 were enrolled and 12 491 patients were included. Heterogeneity, except for threshold effects, was found within these studies. A meta-analysis was performed using the random effect model. Pooled accuracy indicators like sensitivity, specificity, and diagnostic odds ratio of ImmunoCyt™ and cytology were 0.75 (0.73-0.77) vs. 0.45 (0.43-0.48), 0.73 (0.72-0.74) vs. 0.97 (0.96-0.97), and 10.97 (7.53-15.99) vs. 16.40 (10.57-25.46), respectively. The sensitivity of both was increased with the increase of tumor grade and stage. The area under summary receiver operating characteristics curve was 0.834 4 and 0.853 4 and the Q index 0.766 7 and 0.785 3 for ImmunoCyt and cytology, respectively. Combination of both can obviously improve the accuracy of diagnosis.</p><p><b>CONCLUSIONS</b>ImmunoCyt has a high sensitivity in detecting BC, but its specificity is low. As an important adjunct, ImmunoCyt™ can not replace cytology, but combined with cytology it could improve sensitivity with high specificity in the detection and postoperative monitoring of BC.</p>

RÉSUMÉ

<p><b>BACKGROUND</b>Overactive bladder (OAB) is a series of symptoms with high prevalence in elderly people. This study was conducted using the overactive bladder symptom score (OABSS) to evaluate the efficacy of solifenacin succinate for the treatment of OAB.</p><p><b>METHODS</b>This was a prospective, multicenter, single-arm, 12-week study that enrolled 241 OAB patients. The patients received 5-10 mg/day solifenacin. Changes in OABSS, symptoms from voiding diary, perception of bladder condition (PPBC) score, international prostate symptom score (IPSS) and quality of life (QOL) were evaluated at weeks 0, 4, and 12. The relationship between OABSS and PPBC score or parameters of voiding diary was also evaluated.</p><p><b>RESULTS</b>At baseline, the mean OABSS for all patients was 9.41 ± 2.40, and was reduced significantly at week 12 (-3.76 points; 61.21%, P < 0.0001). The OABSS subscore, PPBC score, IPSS, and QOL were also significantly reduced during the study (P < 0.0001). The overall incidence of adverse events was 19.91% (44 cases). The gastrointestinal system was the most commonly affected (11.31%). Around 5.88% of the cases had adverse events related to the genitourinary system. There was a strong correlation between OABSS and urinary symptoms that was recorded in the 3-day voiding dairy.</p><p><b>CONCLUSIONS</b>We showed that solifenacin was clinically effective for relieving OAB symptoms, considering the balance between efficacy, patients' well-being, and tolerability. OABSS integrates four OAB symptoms into a single score and can be a useful tool for research and clinical practice.</p>

RÉSUMÉ

OBJECTIVE@#To study the effect and outcome of Boari bladder flap plasty surgery for the treatment of kidney-sparing strategy for patients with middle and lower ureteral carcinoma.@*METHODS@#Database at the department of urology in the Second Xiangya Hospital from 2002-2007 was screened and all cases of primary solitary lower ureteral carcinoma treated with Boari bladder flap plasty surgery or radical nephroureterectomy were collected. We performed a retrospective review of the clinical data including sex, age, smoking history, tumor site, size, stage, grade, bladder recurrence, renal function et al and evaluated survival rate. The Cox proportional hazards regression model was build to analyze the correlation between each variable and survival time.@*RESULTS@#Thirty nine patients in total were enrolled, including 16 cases underwent Boari bladder flap plasty surgery and 23 cases underwent radical nephroureterectomy. The median follow-up time was 53 months (range 10-84 months). During the follow-up time, 18 patients died, including 6 patients treated with Boari bladder flap plasty surgery and 12 patients treated with radical nephroureterectomy. The estimated bladder recurrence-free survival rate and cancer-specific survival rate at 5 years were 63% vs 59% and 73.8% vs 73.5%, respectively (P>0.05). The survival rate at 5 years and the overall survival rate were 61% vs 57 % and 64.8% vs 58.1% respectively in the 2 groups (P>0.05). There was no significant difference in renal function before surgery between the two groups [creatinine clearance 57 (32-104 ) mL/ min vs 55 (30-102) mL/ min, P>0.05]. Patients underwent Boari bladder flap plasty showed better renal function than patients underwent radical nephroureterectomy [creatinine clearance 55 (35-102) mL/ min vs 43 (30-89) mL/min, P<0.05]. In multivariate Cox regression analysis, the tumor size, pT stage, tumor cell grade and the estimated glomerular filtration rate level were independent factors that affected the overall survival rate of the patients (P<0.05). The tumor size, pT stage and tumor cell grade were positively correlated to the survival time, and the estimated glomerular filtration rate was negatively correlated to the survival time.@*CONCLUSION@#Boari bladder flap plasty surgery could be used to treat lower ureteral carcinoma. Compared with radical nephroureterectomy, Boari bladder flap plasty surgery has equal survival rate and shows superior postoperative renal function.

RÉSUMÉ

OBJECTIVE@#To better understand the pre-operation evaluation of donor kidneys from extended criteria donation after cardiac death and to improve the management during and after renal transplantation.@*METHODS@#Both of the donor kidneys were from the donor who underwent liver transplantation 5 years ago in the Center of Organ Transplantation of Central South University. The donor was admitted because of liver function deterioration which led to hepatic coma, brain death, hepatorenal syndrome and cardiac death sequentially. Deceased donor score (DDS) and "zero point" kidney biopsy were applied to evaluate the donor kidney. After thorough examination of the donor and the renal function, renal transplantation was performed on 2 recipients.@*RESULTS@#The recipients were followed up by 6 months, both of whom developed pulmonary infection and relieved after treatments. The kidney grafts functioned well and no surgical complication and no acute rejection occurred during the follow-up.@*CONCLUSION@#Proper evaluation of the donor organs ensures the safety of renal transplantation with kidneys from cardiac death donors who underwent liver transplantation, which is an important way to increase the number of organs for transplantation, yet the long-term effects need further observation.

OBJECTIVE@#To analyze efficacy and safety of percutaneous nephrolithotomy (PCNL) in the management of staghorn calculi with solitary kidney.@*METHODS@#Between April 2009 and December 2011, 13 patients with renal staghorn calculi in solitary kidney were treated by PCNL in our hospital. The therapeutic effects and complications were the main points of the analysis.@*RESULTS@#Of the 13 patients, surgery time was 92-164 (117.2±21.5) min; 9 cases underwent PCNL through a single access tract, 4 cases through multi-access tracts. The stone removal rate in one session of PCNL was 76.9%, and the total clearance rate was 92.3%. Hemoglobin dropped 11-32 (16.4±4.6) g/L; one case required blood transfusion; no patient had embolism. Hospital stay was 5-10 (6.9±1.5) days postoperatively. Serum creatinine before PCNL in these patients was 83-237 (146.24±38.73) μmol/L compared to 81-242 (134.56±21.52) μmol/L by the end of the 1-month follow-up period (not statistically different). Similar findings were observed in glomerular filtration rates: before PCNL it was 42-114 (71.32±20.82) mL/min and by the end of the 1-month follow-up it was 55-117 (79.40±22.14) mL/min (not statistically different).@*CONCLUSION@#PCNL is effective and safe for the treatment of staghorn stones in solitary kidney, and has advantages such as short surgical duration, fewer complications, rapid recovery, short hospital stay, effective stone removal rate, and so on.

RÉSUMÉ

To improve the diagnosis and treatment of renal oncocytoma and avoid unnecessary radical nephrectomy. The clinical data of 6 cases of renal oncocytoma diagnosed at the Second Xiangya Hospital Central South University from March 2005 to November 2010, including symptoms, laboratory tests, imaging, style of operation, pathological examination, and follow-up were retrospectively analyzed.There were no special symptoms and obvious abnormal laboratory tests in the patients. Two patients had relatively special imaging. Partial nephrectomy was performed in 2 cases of renal oncocytoma with typical imaging, while radical nephrectomy was performed on other patients because of misdiagnosis. No relapse and metastasis were found in the following 1 to 5 years.Renal oncocytoma is an uncommon benign tumor. Partial nephrectomy or tumor excision can be performed on patients diagnosed with renal oncocytoma according to typical imaging and intraoperative frozen section biopsy. The final diagnosis depends on pathological examination and regular follow-up is imperative for patients with renal oncocytoma.

ObjectiveTo explore the effect of metabolic syndrome (MS) on the occurrence and development of benign prostate hyperplasia (BPH).Methods 101 elderly BPH patients were divided into two groups:BPH (n = 45) and BPH with MS (n= 56)group.The effects of metabolic indexes,including body mass index (BMI),waist,high density lipoprotein cholesterol (HDL-C),fasting blood glucose (FBS) and insuline resistance index (H()MA-IR),on prostate volume(PV),prostate-specific antigen (PSA),international prostate symptom score (IPSS) and lower urinary tract symptoms (LUTS) were surveyed in BPH patients.Results BPH with MS group showed significantly higher values of PV (t = 3.22,P= 0.003)and longer course of LUTS (t= 2.02,P =0.046) than BPH group.The BPH patients with overweight and obesity had significantly higher levels of PV(49.44±26.83 ml and 51.7±22.2 ml,P=0.021 and 0.043) than BPH patients with normal weight (38.10 ± 10.64 ml).Additionally,BPH patients with abdominal obesity had significantly higher levels of PV than BPH patients without abdominal obesity(50.26±26.51 ml vs.38.99± 11.25ml,P=0.005).BPH patients with low HDL-C had significantly higher PV than BPH patients with normal HDL-C[(54.23±28.92)ml vs.(40.40± 14.87) ml,P=0.009].The values of PV,PSA in the BPH patients with elevated FBS were significantly higher than in BPH patients with normal FBS (t=3.17 and 2.4I,P= 0.035 and 0.013).BPH patients with insuline resistance (IR) had higher values of PV and longer courses of LUTS than BPH patients without IR (t= 3.43 and 3.58,P-0.001).The PV was positively correlated with BMI(r= 0.459.P= O.OOO),FINS (r= 0.42,P=O.OOI),HOMA-IR (r= 0.49,P= 0.003) and gatively correlated with HDL-C (r= 0.38,P-0.000)- Multiple linear stepwise regression analysis showed that PV was closely correlated with HOMA-IR.ConclusionsMS has evident effects on the occurrence and development of BPH.

RÉSUMÉ

OBJECTIVE@#To review the technical details of retroperitoneoscopic ureterolithotomy and evaluate the clinical effect.@*METHODS@#Between June 2004 and December 2008, 69 patients (55 males and 14 females) with upper ureteral calculus received retroperitoneal laparoseopic ureterolithotomy (40 left sides and 29 right sides). The stone size ranged from 1.5 to 3.1 cm [(2.2±0.6) cm].@*RESULTS@#All the patients underwent retroperitoneoscopic ureterolithotomy. The operation time was 40-295 (63.1±19.8) min,and the blood loss was 30-150 (57.2±23.0) mL.The hospital stay was 5-8 (6.7±1.3) d. During the followup, there was neither ureteral stricture nor recurrent calculus.@*CONCLUSION@#Retroperitoneoscopic ureterolithotomy is safe, effective and minimally invasive, which may replace the conventional open surgery.

RÉSUMÉ

To discuss the pathology, clinical manifestation, diagnosis, therapy and prognosis of mature teratoma in adrenal gland. We reported 2 cases of mature adrenal teratoma and summarized their characters. No local recurrence or metastasis was found in the close follow-up of the 2 patients after the radical resection. Teratomas are rare germ tumors with potential malignant character which usually occur in the testes and ovaries. Adrenal teratomas are extremely rare and the diagnosis relies on radiological examinations. Early diagnosis and early surgical resection are the key in the treatment. Whether the postoperative chemotherapy is needed depends on the pathological result. Close lifelong follow-up is recommended and the prognosis is unclear at present.
