RESUMO
Some locally advanced tumors involving multiple abdominal organs without distal metastasis may cause digestive tract obstruction.Some of these patients can achieve long-term survival after Ro resection,others can obtain digestive tract obstruction relief,pain anesis and survival prolongation after R1 resection combined with postoperative comprehensive treatment.In this review,the efficacy of complex pancreaticoduodenectomy combined with organs resection was introduced based on reviewing the literatures.After the surgery,some patients achieved R0 resection and long-term survival,and the quality of life was significantly improved in some patients.
RESUMO
Objective To study the changes of insulin-like growth factor-1(IGF-1) in serum of patients with obstructive jaundice.Methods The clinical data of 20 patients with obstructive jaundice were collected and the measurement of serum TNF-?,ALT, ALP, endotoxin and IGF-1 were performed. Results The serum IGF-1 in obstructive jaundice was significantly lower than that in gallbladder stone(P
RESUMO
Objective To study the changes of lipopolysaccharide binding protein (LBP) in the serum of Wistar rats with obstructive jaundice and to investigate its potential mechanism.Methods Eighty male Wistar rats were randomly divided into obstructive jaundice group (OJ group, n =40) and sham operation group (SO group, n =40). Before operation and the 5th, 10th, 15th, 20th day after common bile duct ligation, the levels of LBP, endotoxin, tumor necrosis factor alpha (TNF ?) and interleukin 6 (IL 6) in plasma were detected in all the rats. Results LBP levels in serum increased significantly in OJ group on the 10th day after operation compared with those of SO group. Moreover, LBP levels gradually increased in OJ group with the prolongation of obstructive time. A positive correlation existed between serum LBP and plasma endotoxin, TNF ? and IL 6.Conclusion The study demonstrates that LBP in serum is high and plays an important role in the pathogenesis of multiple organ injury secondary to obstructive jaundice. It may be an appropriate way to treat patients with obstructive jaundice by decreasing LBP levels in serum.
RESUMO
Objective To analyse the significance and relation between soluble P-selectin (sP-selectin),D-dimer (D-d) and endotoxin (ET) in the patient with obstructive jaundice (OJ). Methods Blood plasma sP-selectin and D-d in OJ group,acute cholecystitis group and healthy group were detected by ELISA and ET was detected by the colorimetric method, Results In healthy group,the concentration of blood plasma sP-selectin was ( 93.43 ? 17.65 ) ng/ml,ET(0.0030?0.0004)EU/ml,and D-d(0.39?0.21)mg/L; in acute cholecystitis group,sP-selectin was (233.32?82.12) ng/ml, ET(0.4012?0.1506) EU/ml,and D-d(0.76?0.27)mg/L; in OJ group,sP-selectin was (351.90?93.83) ng/ml ,ET (0.3814?0.1430)EU/ml,and D-d(2.14?0.37)mg/L.The sP-selectin, D-d and ET in the acute cholecystitis group and the OJ group were higher than those in healthy group (P 0.05). sP-selectin and D-d in the OJ group were significantly higher than that in the acute cholecystitis group (P
RESUMO
ObjectiveTo study the relationship between the expression of carbohydrate antigen 72-4(CA72-4) in pathology negative lymph nodes from patients with gastric carcinoma and micrometastases. MethodsA total of 385 perigastric negative lymph nodes from 65 patients were immunohistochemically stained with tumor-associated glycoprotein by S-P. ResultsThe lymphatic micrometastases of gastric carcinoma were identified in 14 of 65 patients (21.5%) and in 26 of 385 negative-nodes (6.8%). The incidence of micrometastases was significantly higher in patients with diffuse type than intestinal type(35.5% vs. 8.8%,P
RESUMO
Objective To explore the expression of insulin-like growth factors and their receptor (IGF- I R) in a human colorectal cancer cell line HT-29, and the effect of two IGF- I R monoclonal antibodies on the biological behavior of HT-29 cell lines. Methods Immunohistochemistry was used to test the expression of IGF- I R in HT-29 cell lines. MTT assay was used to determine the anti-proliferation effects of IGF- I R monoclonal antibody (McAb). Apoptosis percentage was estimated by flow cytometry ( FCM). Results IGF- I R was expressed in the membranes of HT-29 cell lines. McAb of IGH- I R can inhibit the proliferation of HT-29 cell lines in a dose-dependent manner. The apoptosis rate of HT-29 cells treated by IGF- I R McAb was higher than that of control group (P
