Objective To evaluate the efficacy and safety of ureteral stenting after transurethral resection ( TUR) of bladder tumors involving the ureteral orifice.Methods From March 2009 to November 2015,34 cases of non-muscle invasive bladder tumor including 28 male and 6 female aged from 26 to 79 years( mean 51 years) were treated by TUR.14 cases had single tumor and 20 had multiple tumors,and 29 were primary and 5 were recurrent.All the patients had tumors involving the ureteral orifice without preoperative hydronephrosis revealed by IVU or CTU examination.The tumors were resected into the deep muscle layer and the involved ureteral orifices were resected during the procedure,and after that a double-J ureteral stent was placed in 18 cases.All patients received one immediate intravesical instillation of 50mg epirubicin after TUR, and further scheme of adjuvant intravesical chemotherapy instillations were made according to the pathological diagnosis.Ureteral stents were removed 10-12 weeks after TUR,and cystoscopy and urinary tract ultrasound examinations were performed every 3 months for 1-2 years postoperatively. Results The operations were successful without complications.No serious adverse reaction occurred in immediate and further adjuvant intravesical chemotherapy.During the follow-up period of 3-71 months, no ureteral stricture, hydronephrosis or tumor recurrence in the upper urinary tract occurred in all the 18 patients with ureteral stent, and the resected ureteral orifices recovered well with normal appearance and ejecting urine.Hydronephrosis was observed in 3 of 16 patients without ureteral stent including 2 cases of nontumoral stenosis at the ureterovesical junction requiring ureteral reimplantation and 1 case of lower ureteral tumor on the involved side requiring nephroureterectomy and bladder cuff excision.No patient complained of symptoms secondary to vesicoureteral reflux or continuous unrelievable lower urinary tract symptoms.2 cases of bladder tumor recurred out of the resected area.Conclusions Ureteral stenting after TUR of bladder tumors involving the ureteral orifice can prevent stricture at the ureterovesical junction without increasing the risk of tumor cell seeding along the upper urinary tract.The existence of a double-J ureteral stent does not increase complications of adjuvant intravesical chemotherapy, and also won't cause intolerable lower urinary tract symptoms.

Objective:To investigate the methods and complications of ultrasound-guided percutaneous nephrostomy (PCN) for treat-ing cancer-related hydronephrosis. Methods:From June 2003 to December 2015, 289 patients (342 kidneys) with cancer-related hy-dronephrosis were treated by ultrasound-guided PCN in Fujian Provincial Hospital. Among the 97 cases of renal insufficiency, 4 pa-tients were treated with hemodialysis before PCN. Except for the anterior mid calyx of nine kidneys in nine patients, the posterior mid or lower pole calyx of all other kidneys was punctured with ultrasound guidance. With the one-step PCN technique, 8F pigtail nephros-tomy tubes were placed into six kidneys in six patients;with the Seldinger PCN technique, 14F balloon and Malecot catheters were placed into 25 kidneys in 25 patients and 311 kidneys in 258 patients, respectively. Results:No severe bleeding and injury in the intes-tine, liver, spleen, pleura, or lung occurred. Two pigtail tubes were blocked one week after PCN. Seven balloon catheters failed to drain well because of the tip and balloon of the catheters located in the proximal part of the dilated ureters. Four balloons slipped out of the collection system of the kidney because of the auto-deflation of three balloons and one case of meager renal parenchyma failing to hold the balloon after a severe hydronephrosis was emptied. All, except 1, Malecot catheter drained well, and 8/9 PCNs through anteri-or mid calyx were successful. Serum creatinine levels were significantly decreased in all the 97 patients with renal insufficiency, of which 81 cases returned to normal, and no one needed persistent hemodialysis. Conclusion:Ultrasound-guided PCN is safe and effec-tive for treating cancer-related hydronephrosis. For appropriately selected patients, puncturing the anterior mid calyx may be an op-tion without additional complications. One-step pigtail nephrostomy tubes are recommended for patients with poor systemic condi-tions. For patients with long life expectancy or suspected complicated urinary infection, large sized Malecot catheters should be consid-ered.

OBJECTIVETo investigate the association between L296Q polymorphism in the cholesterol ester transfer protein(CETP)gene and type 2 diabetes mellitus(T2DM)and blood lipids.
METHODSPlasma glucose and lipid levels were measured in a total of 303 subjects recruited from the West China Hospital of Sichuan University. The subjects were divided into 4 groups according to the levels of plasma glucose and triglyceride, namely T2DM with hypertriglyceridemia group, group of T2DM with normal triglyceride, group of hypertriglyceridemia without DM and group of normal controls, respectively. Genotypes of L296Q polymorphism in the CETP gene of all subjects were analyzed by real-time fluorescent quantitative PCR(FQ-PCR).
RESULTSNo significant differences were observed in the frequencies of genotypes LL and LQ and the 296Q allele among the four groups (chi-square=3.459, P>0.05; chi-square=3.155, P>0.05, respectively), nor the frequencies of genotypes LL and LQ between the T2DM and non-T2DM, or plasma lipid levels between the 296Q allele carriers and those of genotype LL.
CONCLUSIONNo association was found between the L296Q polymorphism in the CETP gene and T2DM as well as plasma lipid levels in various groups of Chinese in this study.

Objective:
To improve the diagnosis and treatment of primary adrenal cortical carcinoma.
Methods:
The clinical and pathological data of 11 patients who diagnosed as primary adrenal cortical carcinoma by pathology were retrospectively analyzed.The median age was 43 years, including 6 males, 5 females.7 cases(63.6%) got the tumor on the left.9 cases(81.8%) presented the maximum diameter of tumor more than 6 cm, and the average maximum diameter was 12.9 cm.All cases had CT or MRI imaging examination.Among most of them, CT showed mixed density lesions, or MRI showed mixed signal.Only 3 cases(27.3%) were considered adrenal cortical cancer through preoperative examinations.
Results:
11 patients were treated with surgical treatment.Of them, 9 cases(81.8%) had complete resection of tumor.3 cases were lost to follow-up, while other 8 cases were followed up for 5-58 months.3 cases presented tumor-specific death at 5-15 months after surgery, with each 1 case in AJCC stage Ⅱ, Ⅲ and Ⅳ, respectively.Survive were in 5cases, and 3cases of them were tumor-free survival, while the other 2 cases of them had local recurrence.
Conclusion
Adrenal cortical carcinoma is very difficult to diagnose preoperatively.Adrenal cortical cancer should be considered when tumor size more than 4cm and tumor presenting inhomogeneous enhancement.Then, the surgical treatment should be performed as soon as possible, and as appropriate, chemotherapy and other comprehensive treatment should be given subsequently.Clinical and basic research such as genes test may provide more treatment options for advanced tumors in future.
