Objective To explore the prognostic risk factors of low level malignant obstructive jaundice treated with transhapetic biliary drainage.Methods The clinical data of 142 patients with low level malignant obstructive jaundice received percutaneous transhapetic biliary drainage management from January 2010 to June 2013 were retrospectively analyzed.The study parameters included gender,age,tumor type,preoperative obstructive time,preoperative infection,drainage method,Child-Pugh grade,serum total bilirubin (TBIL),albumin (ALB),serum creatinine (SCr),the postoperative declining degree of bilirubin and postoperative antineoplastic therapy.The prognostic risk factors were evaluated.Results Single variable analysis showed that preoperative infection (P =0.006),Child-Pugh grade (P =0.004),SCr (P =0.043),the postoperative declining degree of TBIL (P =0.001) and postoperative antineoplastic therapy (P =0.015) were the related factors for survival time.The further Logistic regression analysis showed that preoperative infection (OR =3.729,95％ CI 1.332-6.363,P =0.040),Child-Pugh grade ≥ 10 scores (OR =0.513,95％ CI 0.375-1.276,P =0.018) and postoperative antineoplastic therapy (OR =0.668,95％ CI 0.210-2.026,P =0.038) were the related factors for survival time.Conclusion In treating of low level malignant obstructive jaundice with transhapetic biliary drainage,the preoperative infection,Child-Pugh grade and postoperative antineoplastic therapy may be the important related factors that affect the patient's survival time,to evaluate the prognosis of these patients has important reference meaning.

Objective To study the expression of Survivin and COX-2 in ampullary carcinoma and their clinical significance.MethodsThe expression of Survivin and COX-2 proteins were tested by EnVision immunohistochemistry in 40 cases of ampullary carcinomas,and 8 cases of normal ampulla of vater as the controls.ResultsThe positive rate of Survivin in ampullary carcinonas was significantly higher than that of the controls(82.5％ vs 0,P ＜ 0.01 ). The expression of Survivin in ampullary carcinoma was correlated with duodenal invasion,pancreatic invasion and lymph node metastasis ( P ＜ 0.05 ).Significant difference was also observed in the expression rate of COX-2 between the patients with ampullary carcinoma and the normal controls (67.5％ vs 0,P ＜ 0.01 ).The expression of COX-2 in ampullary carcinoma was correlated with duodenal invasion,pancreatic invasion and lymph node metastasis (P ＜ 0.05). Significantly positive correlation was found between the expression of Survivin and COX-2 by using spearman correlation analysis ( r =0.383,P =0.015).ConclusionThe specific up-regulation of COX-2 gene and Survivin gene may play an important role in the genesis and development of ampullary carcinoma.COX-2 and Survivin may be used as early diagnosis markers and potential therapeutic targets in ampullary carcinoma.

Objective To study the expressions of survivin and PTEN in ampullary carcinoma and their clinical significance.Methods The expressions of Survivin and PTEN proteins were tested by EnVision immunohistochemistry in 40 cases of ampullary carcinomas and 8 cases of normal ampulla of vater as control.Results The positive rate of Survivin in ampullary carcinomas was significantly higher than normal human controls (82.5％ vs 0％,P ＜ 0.01 ).The differences of the expression of Survivin in ampullaty carcinoma of duodenal invasion,pancreatic invasion,and lymph node metastasis were significant ( P ＜0.05 ).Significant differences were also observed in the expression rate of PTEN hetween the patients with ampullary carcinoma and the normal controls (50％ vs 100％,P ＜ 0.01 ).The differences of the expression of PTEN in ampullary carcinoma of duodenal invasion,pancreatic invasion,and lymph node metastasis were significant ( P ＜ 0.05 ).Significantly negative correlation was found between the expression of Survivin and PTEN by using spearman correlation analysis ( r =-0.57,P ＜ 0.01 ).Conclusions The abnormal expression of Survivin and PTEN gene may promote tumor genesis and progression of ampullary carcinomas and it may be used as the marker for prognosis.

Objective To establish a method of quantiying trace α-galactosidase from Bacteroides fragilis in enzymatic conversion of blood group B to O red blood cells ( B-ECO RBCs) .Methods BALB/c mice were immunized with purified recombinant B.fragilisα-galactosidase ( the purity>90%) to prepare monoclonal antibodies.The ascites were prepared using hybridoma cell lines stably secreting antibody and purified by HiTrap rProtein A column.The antibody titer and spe-cificity were detected by ELISA and Western blotting, respectively.Purified monoclonal antibody and rabbit polyclonal an-tibody were applied to detect residual enzyme in B-ECO RBCs and the washing solution was analyzed by indirect ELISA. Results A high titer and purity antibody was obtained.Western blotting showed that the antibody specifically reacted with B.fragilisα-galactosidase.Moreover, indirect ELISA was sensitive enough to detect the minimal amount of residualα-gal-actosidase at the concentration of 1 ng/ml.After four repeat washing cycles with 1∶4 ( v/v) phosphate-buffered saline, the amount of residual enzyme in B-ECO RBCs was less than 10 ng/ml.Conclusion An effective method of detecting the min-imal amount of residual α-galactosidase in blood conversion is established for safety evaluation of universal RBCs prepara-tion by enzymatic treatment.

Objective To investigate the expressions of cancerous inhibitor of protein phosphatase2A (CIP2A),phosphatidylinositol 3-kinase(PI3K),and survivin in pancreatic carcinomas and their clinical significance.Methods The expressions of CIP2A,PI3K,and survivin proteins were tested by immunohistochemistry in 64 cases of pancreatic carcinomas and adjacent paracancerous tissues.Results The positive rate of CIP2A in pancreatic carcinomas was significantly higher than adjacent paracancerous tissues (70.3％ vs 5.6％,P ＜0.05).Significant difference was observed in the expression rate of PI3K between the patients with pancreatic carcinomas and paracancerous tissues (73.4％ vs 8.3％,P ＜0.05).Significant difference was also observed in the expression rate of survivin between the patients with pancreatic carcinomas and paracancerous tissues (75.0％ vs 2.8％,P ＜0.05).CIP2A,PI3K,and survivin were significantly differentially expressed in pancreatic carcinoma among different tumor differentiation,tumor node metastasis (TNM) stage,and neural invasion and lymph node metastasis (all P ＜ 0.05).Spearman correlation analysis showed significantly positive correlation between the expressions of CIP2A and the others (PI3K and survivin) (both P ＜0.05),and between the expressions of PI3K and surviving (P ＜0.05).Conclusions CIP2A was involved in the development of pancreatic carcinomas and might activate the PI3K/Akt/survivin pathway.Our data identified CIP2A as a critical oncoprotein involved in cell proliferation,invasion,and metastasis.It could serve as a therapeutic target for pancreatic carcinomas.

OBJECTIVE Toexploretheantidepressanteffectsofalbiflorinandtheinvolvementof hypothalamic-pituitary-adrenocortical (HPA) axis function in its antidepressant potency.METHODS Two weeks after the olfactory bulbectomized (OB)surgery,albiflorin (2.5 ,5.0 ,10.0 mg·kg -1 ,ig) and imipramine 5.0 mg·kg -1 (ig)were given to rats twice a day for 14 d.The open-field test was con-ducted to evaluate the move ment distance,move ment ti me and velocity of olfactory bulbecto mized rats and sham-operated rats.The serum levels of corticosterone(CORT)and adrenocorticotropic hormone (ACTH)in rats were measured by the enzyme linked immunosorbent assay.The expression levels of glucocorticoids receptor (GR)in the hippocampus of the rats were analyzed using Western blot proce-dures.RESULTS Comparedwithsham-operatedrats,movementdistance,movementtimeandveloci-ty of the OB rats were significantly increased (P<0.01 ).Albiflorin 1 0.0 mg·kg -1 significantly reduced the movement distance,movement time and velocity of OB rats (P<0.05)after being given for 7 d. The movement properties were significantly reduced by albiflorin 5.0 and 10.0 mg·kg -1 when given for 14 d (P<0.05).The OB rats demonstrated significantly increased levels of serum CORT and ACTH (P<0.01 )and decreased GR expression in the hippocampus (P<0.01 ).Albiflorin 2.5,5.0 and 10.0 mg·kg -1 significantly reduced the serum CORT and ACTH levels (P<0.05),while albiflorin 5.0 and10.0mg·kg-1increasedtheexpressionofhippocampalGR(P<0.05).CONCLUSION Albiflorin may have re markable behavioral antidepressant effects on olfactory rats and one of the related mecha-nis ms may be its regulation of the hyperactivity of HPA axis function.
