Abstract

ABSTRACT Background: The technique of laser en bloc resection of bladder tumor (ERBT) has been a valuable alternative technique to transurethral resection of bladder tumor (TURBT). However, the combination of laser ERBT and endoscopic submucosal dissection (ESD) technique has not been well studied. Here, a novel technique integrating a high-power green-light laser with ESD was presented. This study aimed to evaluate the safety and efficacy of high-power green-light laser endoscopic submucosal dissection (HPL-ESD) for the treatment of primary non-muscle-invasive bladder cancer (NMIBC). Materials and Methods: From January 2015 to December 2018, a total of 56 patients with NMIBC underwent HPL-ESD. All tumors were transurethral en bloc resected in the ESD technique. Perioperative clinical data were retrospectively collected and analyzed. Results: All operations were safely performed by the technique of HPL-ESD without blood transfusion. The mean tumor diameter was 2.04 ± 0.65 cm, ranging from 0.5 to 3.5 cm. The mean operative time was 28.39 ± 16.04 min. The average serum hemoglobin decrease was 0.88 ± 0.54 g/dL. The mean postoperative catheterization time was 2.88 ± 0.94 days. The pathologic stages included pTa (32 cases), and pT1 (24 cases). Double-J stent indwelling was not performed for four patients whose tumors were adjacent to the ureteral orifice and no postoperative hydronephrosis was observed. Only one case of ectopic bladder tumor recurred due to irregular bladder irrigation during the 36-month follow-up. Conclusion: HPL-ESD is a safe and effective alternative for the treatment of primary NMIBCs, especially for tumors adjacent to the ureteral orifice.

Features and antitumor activity of the system were investigated.Results: Under the effect of external magnets, the mMWCNTs-EPI system showed sustained release and prolonged retention behavior and better antitumor activity than free EPI. The mMWCNTs-EPI system had higher efficiency in enhancing cytotoxicity and inhibiting proliferation in vitro and in vivo than free EPI. Our studies also revealed the atoxic nature of mMWCNTs.Conclusion: These findings suggested that mMWCNTs are effective intravesical instillation agents with great potential for clinical application.

Abstract

Abstract: A series of solid base catalysts based on potassium salts (K2CO3, K2SiO3 and KAc) supported on mesoporous silicas (SBA-15 and AlSBA-15) were prepared by impregnation method and used to catalyze the transesterification of Jatropha oil with methanol. The prepared catalysts were characterized by several techniques such as X-ray diffraction (XRD), Brunauer–Emmet–Teller method (BET), transmission electron microscopy (TEM) and temperature-programmed desorption of CO2 (CO2-TPD). In addition, various parameters affecting catalytic activity and biodiesel yield were investigated. The results showed that Al element dopant in SBA-15 could protect the pore structure of supported catalyst. The basicity and catalytic activity of AlSBA-15 silica were improved significantly after loading potassium compounds. The activity of K2SiO3 impregnated catalyst was superior to those of K2CO3 and KAc impregnated catalysts. A biodiesel yield of 95% was obtained (using the K2SiO3/AlSBA-15 catalyst) with 30wt.% of K2SiO3 loading on AlSBA-15 support, methanol/Jatropha oil molar ratio 9, reaction temperature 60°C, reaction time 150min and catalyst/oil mass ratio 3%. Reuse of the catalyst indicated that the K2SiO3/AlSBA-15 had steady catalytic activity compared with traditional KOH and K2CO3 catalysts. After being reused for 5cycles, a modest decrease of its activity led to a reduction of about 6% in the biodiesel yield. This decrease of catalytic activity was mainly caused by the potassium leaching and the adsorption of organic deposits on the catalyst surface. [Copyright &y& Elsevier]
