Objective To compare differential diagnostic value of narrow-band imaging (NBI) magnifying endoscopy and magnifying chromoendoscopy.Methods A total of 92 lesions from 75 patients were examined with conventional colonoscopy,NBI magnifying endoscopy and magnifying chromoendoscopy to evaluate pit patterns and vascular morphology patterns.Endoscopic findings were compared with the pathological results.Results The detection rate of conventional endoscopy,NBI magnifying endoscopy and magnifying chromoendoscopy were 94.6% (87/92),97.8% (90/92) and 100.0% (92/92),respectively.NBI magnifying endoscopy was superior to the magnifying chromoendoscopy (P =0.000) in the the lesion contour and microvessels pattern detection,but there was no difference in the pit patterns detected with the two techniques (P =0.394).Consistency,sensitivity,and specificity of NBI magnifying endoscopy in diagnosis of colorectal neoplastic lesions were 91.3% (84/92),83.9% (26/31),95.1% (58/61),respectively,while these variables of magnifying chromoendoscopy were 89.1% (82/92),80.6% (25/31),93.4%(57/61),which were not statistically significant (P > 0.05).Conclusion Differential diagnostic value of NBI magnifying endoscopy and magnifying chromoendoscopy for colorectal neoplastic and non-neoplastic lesions was similar,but NBI magnifying endoscopy displays the lesion contours and microvessels clearlier,and is easy to manipulate.

Objective To investigate the relationship between truncating mutations of APC gene and sporadic colorectal cancer,and analyze the feasibility of non-radioactive protein truncation test (PTT) in the detection of mutations of APC gene.Methods Ninety-six samples of sporadic colorectal cancer tissues ( including 44 patients with colonic cancer and 52 patients with rectal cancer) were obtained from the General Hospital of Ningxia Medical University from September 2008 to September 2010.The mutation cluster region of the APC gene was screened using digital PTT labeled with fluorescent Lys-t-RNA,with a polymerase chain reaction fragment amplified from genomic DNA serving as a tenplate for in vitro translation.The occurrence of gene mutation was determined according to the emergence of truncated peptides.The mutation cluster region of the APC gene in 46 samples of colorectal cancer tissues was analyzed by direct sequencing.The detection rates of the 2 methods were compared by chi-square test.Results Thirteen (26%) truncated peptides were detected in the 50 samples of colorectal cancer tissues.The mutation type of 4 samples is nonsense mutation,which resulted in emergence of truncated gene products.Eleven (24%) truncated peptides were detected in the 46 samples of colorectal cancer tissues.There was no significant difference in the detection rates between PTT and direct sequencing ( x2 =0.033,P > 0.05 ).Conclusions Truncating mutations of APC gene are common alterations in sporadic colorectal cancer in the Chinese.Digital PTT labeled with fluorescent Lys-t-RNA is rapid and high-sensitive in screening gene mutations.

Objective To determine the effect of omental flap wrapping of pancreaticoduodenectomy on postoperative pancreatic fistula and intra-abdominal bleeding in patients undergoing pancreaticiduodenectomy through meta-analysis of published studies.Methods Articles about whether omental flap wrapping could prevent postoperative pancreatic fistula and intra-abdominal bleeding were searched in databases of MEDLINE,PUBMED and EMBASE.14 English article were found and according to including and excluding criteria,4 eligible articles with a total of 2971 patients were selected.Random effects model was used to analyze odds ratios and 95% confidence intervals (CIs).Results 1129 patients were in omental wrapping group,and 1842 patients in nonomental wrapping group.Omental roll-up during pancreaticoduodenectomy could not prevent postoperative pancreatic fistula (OR =0.81,95 % CI 0.40~1.63,P>0.05) or postoperative abdominal bleeding (OR=0.67,95% CI 0.28~1.59,P>0.05).The sensitivity analysis showed the pancreatic fistula rate was lower in the nonomental roll-up group than that in the omental roll-up group (OR=1.24,95% CI 1.03~1.50,P<0.05).Conclusions Omental wrapping can not decrease the risk of pancreatic fistula and abdominal bleeding after pancreaticoduodenectomy.Further randomized controlled trials are needed to identify the effect of omental wrapping technique for pancreaticoduodenectomy.

OBJECTIVETo Understand the characteristics of the common complications in the gastric malignant tumor inpatients in our country, the related traditional Chinese and western medicine combined usage.
METHODBy using the method of frequency analysis and correlation, analysis the diagnostic and Prescribing information in HIS database of 20 national first-class ternary general hospital inpatients.
RESULTThe most common coexistent disease are malignant tumor in other parts, benign tumor. The most common complications are serous cavity effusion, lung infection, abnormal liver function. In other parts malignant tumor, more than 50% with advanced gastric malignancy; in other parts benign tumor, 86.00% located in the digestive and Urinary system, in the complications, digestive system diseases accounted for 23.80%; further according to the association rules of data mining, and calculate the combination scheme of the most commonly used for acid suppression drugs in combination with the centralizer and eliminate pathogenic traditional Chinese medicine (TCM).
CONCLUSIONIn the real world, most of the gastric malignant tumor disorder crowd is in the advanced stage, with lymph nodes and other parts of the transfer; and at the same time to incorporate the spleen and kidney disease in TCM zang-fu organs dialectical, should notice the reach mark early intervention, achieve the purpose of cure not ill; acid suppression hemostatic drugs combined the centralizer and eliminate pathogenic the three medicine combined treatment of Chinese traditional medicine is relevant.
