Results:All the feeding tubes were inserted to jejunum successfully.The time was 10-40 minutes,averagely 20 minutes.Conclusion:The placement of the nasojejunal feeding tube under X-ray is simple and safe and offer an effective route of early enteral nutrition for critical illness.

A 300 cm-long ileus tube was inserted from nasal cavity to the jejunum under the radiophotography guidance in 16 patients with recurrent adhesive small-bowel obstruction. Along with entire intestinal decompression, the ileus tube was moved forward to the terminal ileum and remained for 13 to 25 days for internal intubation plication. All the participants improved during the follow-up (range, 8 months to 2 years), and no intestinal adhesion or obstruction occurred. Non-surgical intestinal intubation plication might be a simple, safe and effective treatment for adhesive intestinal obstruction.

Objective To study the relationship of expression of nuclear factor kappab gene and MMP-2mRNA and with lymph node metastasis of pancreatic cancer.Methods The expression of NF-?B was investigated by Western blot in normal pancreatic(NP) samples of 9 cases and pancreatic cancer(PC) samples of 45 cases(lymph node metastasis 30 cases,non-lymph node metastasis 15 cases).The expression of MMP-2mRNA was detected through semiquantitative reverse transcriptase polymerase chain reaction(RT-PCR).Results Of 45 PC cases,the positive expression rate of p65 and MMP-2mRNA was 66.7%(30/45) and(57.7%)(26/45),respectively.Of 30 cases of lymph node metastasis,the positive expression rate of p65 and MMP-2mRNA was 83.3%(25/30)and 73.3 %(22/30),respectively.Of 15 cases of non-lymph node metastasis,the positive expression rate of p65 and MMP-2mRNA is 33.3%(5/15) and 26.7%(4/15),respectively,and the expression of p65 gene was positively correlated with MMP-2mRNA(expression)(r=0.743,P

Objective To summarize the experience in diagnosis,prention and management of right accessory hepatic duct(AHD)injury during laparoscopic cholecystectomy(LC).Method The clini-cal data of 8 patients with AHD injury during LC diagnosed and managed retrospectively analyzed. Results Of the 8 patients, 5 patients were found during LC,3 patients were found after LC.Management were ad follow:5 patients with the diameter of the AHD smaller than 3.0 mm were ligated,1 patient with the diameter of 5.0 mm were reconstructed,1 patient with the diameter of 3.0 mm,but the AHD connected with other bile duct in vicinal epaticlobes,were ligated.These 7 patients,with the injured AHD ligated or re-constructed,were followed up for 6 months to 5 years and showed good results.The another who did not be found during LC and not be managed appropriately,arose serious bile leakage and infection for a long time,underwent drainage operations for 3 times,cured after haft year.No death in all patients.Conclusions Correct operative rules should be obeyed strictly in LC,and keep the exist of AHD under close guard,if AHD injury occurred,LC should turn to open surgery immediately,early finding of the injury and managing appropriately is the key to achieve successful result.

Objective To study the expression of reversion-inducing-cysteine-rich protein with Kazal motifs (RECK) in human pancreatic carcinoma tissues and pancreatic carcinoma cell lines; the effects of recombinant lentiviruses carrying RECK gene(LV-RECK) therapy on human pancreatic carcinoma xenograft in nude mice; and to find out the relationship between the expression of RECK and the prognosis of pancreatic carcinoma.Methods Immunohistochemical method was used to detect the expression of RECK in the resected specimens of pancreatic carcinoma and their corresponding normal pancreatic tissues in 42 patients.Western blotting was used to examine the expression of RECK in human pancreatic carcinoma cell lines (PANC-1,MIAPaCa-2,AsPC-1).Statistical analyses were performed to determine the relationship between RECK expression and the clinicopathological characteristics and prognosis in pancreatic carcinoma.Subcutaneous xenograft tumor models of human pancreatic carcinoma were established in nude mice.These nude mice were then divided into the experimental group,the negative control group and the blank control group randomly.The three groups of nude mice were intratumorally injected with LV-RECK,LV-EGFP and normal saline (NS) respectively.The antitumor effect was studied.Immunohistochemical method was used to detect the expression of RECK and microvessel density (MVD).Terminal deoxynucleotidyl transferase mediated dUTP-DIG nick end labeling (TUNEL) was used to detect the apoptosis of tumor cells.Survival analysis was performed.Results All three pancreatic carcinoma cell lines did not express RECK.The overall positive rate of RECK expression was 45.2 ％ (19/42) in pancreatic carcinoma,and 88.1 ％ (37/42) in normal pancreatic tissue.The expression level of RECK was significantly lower in the tumor tissues than in the normal tissues (P＜0.01).The expression of RECK was significantly associated with TNM stage,lymph node metastasis and local infiltration of pancreatic carcinoma (P＜0.05).Kaplan-Meier survival analysis revealed that the survival time was significantly longer in the RECK positive patient group than in the RECK negative patient group.Univariate Cox regression analysis revealed that RECK expression,TNM stage,lymph node metastasis and local infiltration were significantly related with prognosis for pancreatic carcinoma (P＜0.05).Multivariate Cox regression analysis revealed that only RECK expression remained as an independent significant factor in predicting the prognosis of pancreatic carcinoma (P ＜ 0.001).When compared with the negative control and the blank control groups,the volume of subcutaneous xenograft tumor in the experimental group was significantly decreased (P＜0.05).RECK protein in the experimental group was re-expressed.MVD of the experimental group was significantly less than those of the control groups (P＜0.05).Apoptotic index (AI)of the experimental group was significantly higher than those of the control groups (P＜0.05).The survival time of nude mice in the experimental group was significantly longer than those in the control groups (P＜0.05).Conclusions RECK expression was closely related to invasion,metastasis and prognosis of pancreatic carcinoma and it was an independent prognostic marker.RECK gene over-expression inhibited neovascularization of pancreatic carcinoma,induced apoptosis of tumor cells,inhibited the growth of tumor xenograft and improved the prognosis of tumor-bearing mice.These results suggest a possible new treatment for pancreatic carcinoma.

Objective:To investigate whether PUMA gene transfection can increase sensitivity of pancreatic cancer cells (PC) to 5-FU-induced apoptosis. Methods: PUMA-pCEP4 containing full length PUMA cDNA or pCEP4 was transfected into human pancreatic cancer cell line AsPC-1 by lipofectamine transfection, G418 selection was used to select positive cells. AsPC-1, AsPC-1/PUMA and AsPC-1/pCEP4 cells were separately treated with serial concentrations of 5-FU(0.01-100 ?mol/L). MTT assay was used to determine the cell survival rate in each group and IC50 of 5-FU was calculated. TUNEL,FCM and DNA ladder observation were employed to study cell apoptosis. Western blotting was performed to detect the expression of PUMA protein. Results: The 5-FU IC50 values of AsPC-1, AsPC-1/PUMA and AsPC-1/pCEP4 cells were (12?1.9)?mol/L,(1.6?0.4)?mol/L and (10.4?1.6) ?mol/L, respectively, with the sensitivity of AsPC-1/PUMA cells increased by 7.5 folds. 5-FU induced cell apoptosis of AsPC-1 cells in a dose-dependent manner, with the apoptosis of AsPC-1/PUMA cells more prominent than those of AsPC-1 and AsPC-1/pCEP4 cells. Low concentration of 5-FU (0.1 ?mol/L) induced few apoptosis of AsPC-1/pCEP4 cells([1.14?0.28]%) and AsPC-1 cells ([0.9?0.23]%), and induced apoptosis in AsPC-1/PUMA cells([6.47?1.42]%). High concentration of 5-FU (1.0 ?mol/L) induced apoptosis in all groups, with that in AsPC-1/PUMA cells([34.54?9.36]%) significantly higher than those in AsPC-1/pCEP4 cells([15.8?5.15]%) and AsPC-1 cells ([12.8?3.74]%, both P

Costimulatory molecule CD_(40) is extensively expressed by immune, hematopoietic, epithelial, and a wide range of tumor cells. As a potential target for novel cancer therapy, CD_(40)/CD_(40L) may mediate tumor regression through both an indirect effect of immune activation and a direct cytotoxic effect on the tumor. Several drug formulations that target the CD_(40)/CD_(40L) pathway have undergone phase I clinical evaluation in advanced-stage cancer patients, and initial findings show objective clinical responses immune modulation function and have not serious toxicity.
