Objective To investigate the efficacy and complications of therapeutic ERCP for patients over 80 years. Methods Data of 80 patients aging over 80 years, who tnderwent therapeutic ERCP from August 2007 to August 2009 were retrospectively studied. The etiology, complications and therapeutic effects were evaluated. Results A total of 51 patients (63. 8% ) were accompanied by cardiovascular diseases, and 43 patients were diagnosed as having malignant bile duct stricture (53. 8% ). The overail therapeutic efficacy was 96. 3%. The incidence of post-operative complications was 12. 5% (10/80). Occurrence of complications in patients with malignant tumors ( 18. 6% ) was significantly higher than that in patients with bile duct stones (5.6% ,P <0. 05). Incidence of complications in those with cardiopulmonary diseases was similar with that in patients without (11.8% vs. 13.8%,P>0.05). Conclusion Age more than 80should not be considered as contraindication of ERCP. Therapeutic ERCP is effective in senior patients. Patients with advanced ages shows a relatively high incidence of complication after ERCP, which may not be related to other accompanying diseases.

In proteomic research, to improve protein solubility of membrane proteins and nuclear proteins, buffers containing high concentration of detergent, such as 4% SDS, were widely used. However, high concentration of detergent might severely interfere with the downstream proteomic analysis, including protein quantitation and trypsin digestion. To improve the proteomic compatibility of buffers with high concentration of detergent, we used short gel method to pretreat buffers containing detergent. Protein samples were first separated by a short (2-2.5 mm) SDS-PAGE electrophoresis, and proteins were quantitated by comparing with bovine serum albumin standards via optical density analysis. The gel was then cut and peptides were recovered using in-gel digestion. The quantitative linearity range of this method was 1 to 8 μg. The quantitation was accurate and reproducible. After short gel analysis, recovered peptides generated high mass spectrometry signals. In conclusion, short gel method eliminated the interference of high concentration detergent in the proteomics analysis, and it was suitable for protein samples' pretreatment, and was worth to apply in proteomic research.

Objective To compare the differences between endoscopic resection and laparoscopy?assisted surgery or transanal endoscopic resection for rectal neuroendocrinal tumor. Methods Clinical data of patients who underwent endoscopic or surgical resection of neuroendocrinal tumor of less than 2 cm which were confirmed by pathology from December 2010 to November 2013 were retrospectively analyzed. Results Twenty cases of endoscopic treatment, including 17 cases of ESD, 3 cases of EMR,were included in endoscopy group;while 18 cases treated with surgery were included in surgery group, among which 12 ca?ses underwent transanal endoscopic microsurgery and 6 cases laparoscopic resection. The mean lesion sizes were 7 mm(4?18 mm)and 8 mm(3?15 mm),respectively. Pathology showed there were 16 cases of grade G1 neurocrinal tumor and 2 G2 cases in surgical group. There was no lymphvascular invasion with clear margin in the endoscopy group,but three cases of lymphvascular invasion in surgical group. No treatment?related se?vere adverse event occurred in either group. The time for oral food intake was 2?0 d(1?4 d) in endoscopy group, while that in surgery group was 2?4 d(1?7 d)(P=0?295). The hospital stay was(6?80±2?12) d in endoscopy group and(8?59±2?85)d in surgery group, respectively(P=0?034). And the total hospitalization cost was 10 488(4 128?15 296) yuan and 15 590(3 024?40 503) yuan(P=0?031) in the two groups, re?spectively. The follow?up was 25 months(2?48 months)and no recurrence was found. Conclusion Endo?scopic resection, especially ESD, is a new approach to treat colorectal neuroendocrinal tumor,advantageous over surgery in shorter hospitalization time, minimal invasiveness, faster postoperative recovery, less compli? cation, and reduced hospitalization cost.

Objective To determine the significance of the quantitative parameters obtained from intravoxel incoherent motion ( IVIM) diffusion weighted imaging ( DWI) in differentiating renal tumors from normal renal tissues.Methods Twenty-four patients with surgical pathology-proven renal tumors and 13 volunteers with healthy kidneys were included.DWI was performed with 9 b-values (0, 20, 50, 100, 200, 400, 600, 800 and 1 000 s/mm2).The slow component of diffusion (Dslow), fast component of diffusion ( Dfast ) and fraction of fast ADC ( f) of the biexponential DWI were calculated for the clear cell renal cell carcinoma (CCRCC), the normal renal parenchyma and the non CCRCC ( NCCRCC) .The ADC was calculated for all b-values using linear regression yielding standard ADC ( ADCtot ) .The parameters were compared among the groups, and the receiver operating characteristic ( ROC ) analysis was performed. Results CCRCC showed higher ADCtot (1.73 ±0.43) ×10 -3 mm2/s, Dfast (14.75 ±14.73) ×10 -3 mm2/s, Dslow(1.34 ±0.38) ×10 -3 mm2/s than NCCRCC (ADCtot(1.23 ±0.26) ×10 -3 mm2/s, Dfast(9.47 ± 5.27) ×10 -3 mm2/s, Dslow(0.58 ±0.15) ×10 -3 mm2/s), and the differences of ADCtot(P=0.037) and Dslow(P=0.001) were significant.The normal renal parenchyma showed higher ADCtot (2.25 ±0.11) × 10 -3 mm2/s, Dslow ( 1.74 ±0.17 ) ×10 -3 mm2/s, f ( 35.00% ±9.37%) than CCRCC ( f, 31.13% ± 10.75%) and NCCRCC(f, 33.76%±24.02%), and the differences between the normal renal parenchyma and CCRCC of ADCtot ( P =0.000 ) and Dslow ( P =0.001 ) were significant.There were no differences between the normal renal parenchyma and the tumor ipsilateral renal parenchyma of all parameters.Dslow had higher accuracy ( sensitivity 95%, specificity 100%) in distinguishing CCRCC and NCCRCC, with area under the curve of 0.988.Conclusions Multi-b-value DWI derived quantitative parameters including ADCtot and Dslow may differ significantly between the renal tumor and normal renal parenchyma.Dslow is the best parameter in distinguishing CCRCC and NCCRCC.
