Objective To investigate the relevant factors for fungal infection following pancreatoduodenectomy and offer the theoretical foundation for preventing the emergence of complications after operation. Methods Medical records from 562 consecutive patients who underwent pancreatoduodenectomy in this hospital from 1995 to 2005 were retrospectively reviewed by using single factor and non-condition Logistic regression analyse. Results ①Seventy-eight patients (13.9%) developed invasive fungal infection. The most frequently isolated fungal were Candida albicans accounted for 67.0%, and followed by Candida glabrata, Candida papasilosis and Candida tropicalis and gastrointestinal tract was the most common infection site, followed by respiratory tract, abdominal cavity. ②Fungal infection occurred significantly more often in patients with the length of time in parenteral nutrition, antibiotic use or abdominal cavity complications. Conclusion The most common infection site and isolated fungal associated with pancreatoduodenectomy were gastrointestinal tract and Candida albicans. Abdominal cavity complications such as pancreatic fistula, biliary fistula and abdominal infection and extended use parenteral nutrition and antibiotic are the most important factors leading to invasive fungal infection after pancreatoduodenctomy. Eliminating the various risk factors will decrease the incidence of fungal infection.

0.05). Conclusion CD105 overexpression may play a crucial role in early recurrence of HCC in patients after operation. The expression of CD105 mRNA in the tumor peripheral tissue was much higher than in the tumor center and normal liver tissue, which indicated CD105 was related to early recurrence.

Objective To study on the results of magnifying endoscopy in gastric atrophy, intestinal metaplasia (IM) and dysplasia, and evaluate their feasibility and accuracy for the diagnosis of these lesions. Methods One hundred patients were examined by magnifying endoscopy, Fujinon EG485 ZH modal, and stained with 0. 5% methylene blue. After defining magnifying endoscopic patterns of gastric pits as types A, B, C, D, and E, the diagnostic classification and endoscopic criteria were developed for the diagnosis of atrophy, IM and dysplasia. The results of 417 histopathological biopsy specimens taken from the corresponding areas of gastric mucosa under magnifying endoscopy were regarded as gold standard. Results Sparse and thick gastric pits mainly appeared in gastric atrophy, IM mainly appeared in gastric mucosa of type C, type D, and type E with positive stain, dysplasia appeared as depressed, slightly raised, or flat mucosa accompanied by loss of clear pattern, fine pits or coarse and irregular microstructure. The sensitivity and specificity of magnifying endoscopies in the diagnosis of atrophy, IM and dysphasia were 95. 85% , 95. 09% ; 88. 30% , 90.83% ; and 91.52% , 94. 41% respectively, all were higher than those of routine endoscopy. Conclusion The diagnostic accuracy significantly increased as depending upon the morphological features of gastric atrophy , IM, or dysplasia under magnifying endoscopy.
