Objectives:To investigate the morphologic changes of the colon in the rats after a total small bowel resection. Methods:Ten male Sprague Dawley(350～370 g) rats in the experimental group were undergone resection of total small bowel,and ten normal rats were randomly chosen as the control group.After supported by enteral nutrition for 3 months,rats were sacrificed and the colon harvested for morphologic parameters study. Results:The length,diameter,wet weight,crypt depth,mucosal thickness and kerckring height of the colon in the experimental group were significantly higher than those in the control group( P

Objective To investigate the application of neuronavigator in the resection of neurospongioma and management of brain shift.Methods Operation protocol was made according to three dimensional structure of neumspongioma under neuronavigation.The focus was sought by using viewing wand for the resection.Results All focus were removed under neuronavigator.The size and operation time was associated with brain shift along the operation pathway.Operative approach and depth of lesion was related to brain shift.Loss of large volume of cerebrospinal fluid exerted influences on the shift of codex along the operative pathway and plane side.Conclusion Neuronavigator can effectively protect nerve function when used in the resection of neurospongioma.As for brain shift,strict navigation and operative procedure would be useful for reducing loss of cerebrospinal fluid,removed volume of brain tissue and avoiding early release of tumor hydatid flui.

Purpose To eva1uate the effects of Annexin A3 on pro1iferation and apoptosis of gastric cancer ce11s. Methods The re-combinant p1asmid pYr-ads-4-Annexin A3 was constructed and ana1yzed by restriction ana1ysis and sequencing and was transfected into MGC803 ce11s. The stab1e transfectants were obtained after screening with G418. Western b1ot ana1ysis was used to examine the expres-sion of Annexin A3 before and after transfection. CCK8 assay,c1one assay and f1ow cytometry were used to study the effects of Annexin A3 on pro1iferation and apoptosis of MGC803 ce11s. Results The recombinant p1asmid pYr-ads-4-Annexin A3 was successfu11y con-structed. Western b1otting resu1ts indicated that the Annexin A3 expression was significant1y higher in ce11s transfected with pYr-ads-4-Annexin A3 compared with ce11s transfected with empty vectors and un-transfected ce11s( P<0. 05 ). CCK8 assay resu1ts showed the number of ce11s transfected with pYr-ads-4-Annexin A3 was significant1y higher than those transfected with empty vectors and un-trans-fected ce11s(P<0. 05). Moreover,the number of c1one in ce11s transfected with pYr-ads-4-Annexin A3 was significant1y higher than the other two groups(P<0. 05). Important1y,high Annexin A3 expression inhibited to apoptosis of MGC803 ce11s(P<0. 05). Con-clusion Annexin A3 expression p1ay important ro1es in tumorigenesis of gastric cancer. Annexin A3 cou1d promote the pro1iferation and inhibited apoptosis of gastric cancer ce11s and it might be a potentia1 target for gastric cancer treatment.

Objective To compare the imaging of 99 Tcm‐MNLS and 99 Tcm‐HL91 for the hypoxic assessment in the tumor af‐ter radiotherapy .Methods Twenty four Kunming mice models bearing H22 liver cancer xenografts which tumor were treated ra‐diotherapy for 25 Gy were divided into 99 Tcm‐MNLS instant group ,99 Tcm‐MNLS 48 h group ,99 Tcm‐HL91 instant group ,99 Tcm‐HL91 48 h group and injected the matching 99 Tcm‐MNLS or 99 Tcm‐HL91 to image .The technique of ROI was adopted to calculated the T/NT on the image .Immunohistochemical stain methods were used to evaluate the level of HIF‐1αabout tumors after imaging . Two sample t test was performed .Results The T/NT and the HIF‐1α level about instant (3 .36 ± 0 .20 ,88 .55% ± 0 .83% )were higher than and 48 h (2 .25 ± 0 .43 ,22 .75% ± 3 .35% )in 99 Tcm‐MNLS group(P<0 .05) ,then in 99 Tcm‐HL91 group the T/NT and the HIF‐1αlevel about instant (3 .23 ± 0 .90 ,90 .55% ± 2 .61% )were higher than 48 h (2 .79 ± 0 .85 ,25 .88% ± 3 .76% )(P<0 .05) .The difference of T/NT ,HIF‐1αlevel about instant in 99 Tcm‐MNLS group and 99 Tcm‐HL91 group were no significant(P>0 .05)and the same to the T/NT ,HIF‐1αlevel about 48h in 99 Tcm‐MNLS group and 99 Tcm‐HL91 group(P>0 .05) .Conclusion 99 Tcm‐MNLS hypoxia imaging could provide the change of hypoxia comparable to 99 Tcm‐HL91 ,and the two radiopharmaceutical could both show high accuracy rate in evaluating the hypoxia in the tumor .

Objective To compare the effects between Milrinone and Lrh-BNP for treating the peripartum cardiomyopathy heart failure.Methods After treated by routine measure,39 serious PPCM patients were randomized into two groups,with 20 to Milrinone group for the advanced therapy between 5 to 7 days,and 19 to Lrh-BNP group therapy 24 hours. Results The total efficient rate in Lrh-BNP group(95%) was more higher than that in Milrinone group(73.6%).The index of heart function such as LVEF,FS,E/A,SV,CO,CI,24 hours urine quantity,dyspnea could improve in both groups after the therapy(P

The NF-kappaB pathway regulates the expression of over 150 target genes, e.g., cytokines, chemokines, leukocyte adhesion molecules and inducible effector enzymes. Consequently, it plays a crucial role in innate and adaptive immune responses, inflammatory response, stress responses, apoptosis and so on. IkappaB kinase (IKK) is the key of this pathway, and it owns a special structure which consists of catalytic subunit and regulatory subunit. Naturally, the activation of IKK needs the interaction of the two subunits and phosphorylation by its upstream kinases. Actually, there are two methods of activation of the NF-kappaB pathway, and both of the methods need the IKK complex. Given to the crucial role of IKK, researchers have isolated and synthesized amounts of IKK inhibitors, and these provide a great convenience to develop novel anti-inflammatory and anti-tumor drugs.
