Objective To analyze the postoperative complications in aged patients receiving pancreaticoduodenectomy. Methods Pancreaticoduodenectomy was employed for the treatment of 52 aged patients. Of the 52 patients with a mean age of 70.5(65-76), 32 were male and 20 female. Postoperative pathological examination confirmed that 24 patients suffered from Vater,s ampullary and duodenal cancers, 16 from pancreatic carcinoma and 12 from cholangiocarcinoma. Results The mortality was 7.7%. Severe complications included bleeding (upper gastrointestinal tract or abdominal cavity),MOF, ARDS, postsurgical gastroparasis syndrome(PGS), mental disorder, pancreaticogastrostomy leak and biliary-enteric anastomotic leak et al. Conclusion MOF is the main lethal complication. Incidence of PGS and mental disorder is high.

Objective To investigate the expression and significance of survivin in hepatocellular carcinoma(HCC).Methods All reports published in the past 13 years on survivin and hepatocellular carcinoma (HCC) were reviewed.A Meta-analysis was conducted on these studies and it was used to determine the prognostic significance of the expression of survivin on patients with HCC.Results 18 studies were included into this Meta-analysis.There were 1 021 HCC patients and 208 normal controls.There was a significant difference between the positive rate of survivin in hepatocellular carcinoma and in normal tissues (0R =30.61; 95％ CI:16.67-56.23).The expression of survivin correlated with clinical staging,pathological differentiation,tumor metastasis,portal vein tumor thmmbus,and survival (P ＜ 0.05).There was no correlation with gender,age,AFP,HBsAg,tumor diameter,and tumor capsule (P ＞ 0.05).Conclusiom Survivin can be used as a molecular marker for the definitive prognosis of HCC.It is also a reliable marker in the choice of standardized and individualized therapy.

Neutrophil gelatinase associated lipocalin(NGAL),also known as lipocalin 2,has close relationship with human neoplasias,which is up-regulated in a number of malignancy and involves in the process of tumor development.But it appears to exist paradoxical effects attributed to NGAL in human neoplasias.For instance,through protecting MMP9 from autodegradation,NGAL has a clear pro-tumoral and pro-metastatic effect,as has already been observed in breast cancer and esophageal cancer.However,on the contrary,for pancreatic cancer and ovarian cancer,NGAL can inhibit FAK phosphorylation and vascular epidermal growth factor synthesis,having an anti-tumoral and anti-metastatic effect.This review summarizes the current knowledge about the dual effects of NGAL in the process of tumor development,and attempts to explore the possible underlyins mechanism.
