ObjectiveTo explore the values of CA19-9, CA242, CEA, and CA125 single or combined detection on clinical diagnosis and prognosis for patients with pancreatic cancer. MethodsSerum tumor markers CA199, CA242, CEA, and CA125 of 63 patients with pancreatic cancer, 33 patients with cancer of bile duct, and 27 patients with benign pancreatic disease were detected, and those patients were followed up after operation. ResultsThe levels of CA19-9, CA242, CEA, and CA125 in patients with pancreatic cancer were significantly higher than those in patients with benign pancreatic disease and cancer of bile duct (Plt;0.05). The sensitivity of CA19-9 alone was the highest in the four tumor markers for the patients with pancreatic cancer 〔79.4% (50/63)〕, but the specificity (61.9%) was lower than that of CA242 (83.3%) and CEA (80.0%). The specificity of combined detection of CA199+CA242+CEA was the highest 〔93.3% (56/60)〕. The level of CA19-9 in carcinoma of body/tail of pancreas was significantly higher than that of carcinoma of pancreas head or whole pancreas (Plt;0.05). The serum levels of CA19-9 and CA242 in patients with stage Ⅳ were significantly higher than those in stage Ⅰ or Ⅱ/Ⅲ (Plt;0.05). Fifteen patients were lost to follow up, 48 patients were followed up 2－12 months with an average 6 months. The levels of CA242 and CA199 in patients with pancreatic cancer on 0.5 month and 3 months after operation were lower than those before operation (Plt;0.05). ConclusionsSingle detection of CA19-9 can improve the diagnostic sensitivity, and combined detection of tumor markers CA199+CA242+CEA can improve the diagnostic specificity. CA19-9 or CA242 is a valuable marker for evaluating treatment effects and estimating prognosis.

ObjectiveTo study the clinical manifestations, pathologic characteristics, imaging features, diagnosis and treatment of adenomas of extrahepatic bile duct.MethodsTwo cases of adenomas of extrahepatic bile duct in our hospital and 14 cases reported in the literatures were analyzed retrospectively.ResultsThe patients’(male 5, female 11) mean age was 58.4 years (range 21-85). The main manifestations included jaundice (n=11), abdominal pain (n=8),fever (n=6),dyspepsia (n=4),body weight loss (n=3) and claycolored stool (n=1). The locations of tumors were in the left hepatic duct (n=1), right hepatic duct (n=3), hepatic common bile duct(n=3）,the junction of cystic duct and common bile duct (n=1），distal common bile duct (n=8). The pathologic types were tubular adenomas (n=5), papillary (villous) adenomas (n=10),and mucous adenoma (n=1). All the patients underwent surgical therapy. The tumors were identified by postoperative histopathologic examination.ConclusionIt is difficult to correctly diagnose adenomas of extrahepatic bile duct before operation, because the clinical manifestations are usually atypical. The definite diagnosis should depend on histopathologic examination. It is the key to completely resect the tumors. Postoperative followup should be done on regular basis.
ObjectiveTo evaluate the therapeutic effect of liver transplantation (LT) combined with adenovirus-mediated delivery of herpes simplex virus thymidine kinase / ganciclovir (ADV-TK/GCV) in treatment of patients with hepatocellular carcinoma (HCC), so as to benefit more patients with HCC beyond the Milan criteria. MethodsThe clinicopathologic data of patients with HCC underwent LT by the author team since 2007 were collected and analyzed. The patients were assigned into simple LT group and LT+ADV-TK/GCV group. The 5-year cumulative overall survival rate and relapse free survival rate of all LT patients and the patients with LT beyond the Milan criteria by simple LT and LT+ADV-TK/GCV therapy were compared. Meanwhile, Cox regression was used to analyze the risk factors affecting long-term overall survival rate and relapse free survival rate of all patients with HCC after LT. ResultsA total of 216 patients eligible for inclusion were collected in this study, including 134 patients in the simple LT group and 82 patients in the LT+ADV-TK/GCV group, 162 of whom beyond the Milan criteria, including 101 patients underwent the simple LT and 61 patients underwent the LT+ADV-TK/GCV. There were no statistical differences in the baseline data between the simple LT and LT+ADV-TK/GCV in all patients and patients beyond the Milan criteria (P>0.05). There were no statistical differences in 5-year overall survival rate and relapse free survival rate of all patients with HCC (P>0.05). The 5-year cumulative overall survival rate of the LT+ADV-TK/GCV group was better than that of the simple LT group in the patients beyond the Milan criteria (χ2=4.11, P=0.047), but it was not found that the 5-year cumulative relapse free survival rate had statistical difference (27-month survival time as the critical value, P=0.46, P=0.06). Cox regression multivariate analysis results showed that the larger cumulative tumor diameter, the preoperative elevated serum alpha fetoprotein (>400 μg/L), later TNM stage, and without combination of ADV-TK/GCV therapy increased the probability of shorter overall survival of patients after LT; and the patient’s older age, the larger cumulative tumor diameter, and later TNM stage increased the probability of shorter relapse free survival after LT, and it was not found that the combination of ADV-TK/GCV therapy had an impact on the relapse free survival. ConclusionLT combined with ADV-TK/GCV therapy can obviously improve overall survival among patients beyond the Milan criteria, more patients with advanced HCC will be candidates for LT combined with ADV-TK/GCV therapy.
Objective To review recent studies in molecular biology of gastric cancer. Methods Relevant references were reviewed.

ObjectiveTo study the protective effect of hepatocyte growth factor(HGF) on grafted mucous membrane of transplanted small bowel.MethodsTotal small bowel transplantation was made in inbred Wistar (RT1k) rats heterotopically,either total parenteral nutrition (control group,n=10) or hepatocyte growth factor supplemented TPN (HGF group,n=10) was given to the recipients from the 2nd day to the 10th day postoperatively. Morphological parameters of the transplanted intestinal mucosa, such as mucosal villous height, villous width, crypt depth, mucosal thickness and villous surface area were observed. Variation of ultrastructure of transplanted epithelial cells was observed. Composition of mucosal protein and DNA content were tested. ResultsComparison between HGF group and the control group were as follows. Mucosal villous height (298.79±22.31） μm vs （176.45±14.62） μm, P=0.001, villous width (107.46±12.34） μm vs （74.20±16.85） μm, P=0.004, crypt depth (104.56±11.17） μm vs （74.45±8.34） μm, P=0.000 5, mucosal thickness (409.53±35.83） μm vs （259.38±24.65） μm, P=0.003, and villous surface area (0.101±0.011) mm2 vs (0.041±0.005) mm2, P=0.001 were found significantly increased in HGF group compared with control group, there were no obvious difference decrease as compared to pretransplant parameters.Mucosal protein composition was higher in HGF group than that in control group （89.65±9.28) mg/g wet wt vs (53.73±11.45) mg/g wet wt, P=0.012, baseline (92.64±10.52) mg/g wet wt, nearly equal to baseline; DNA composition was also high in HGF group （0.89±0.09) mg/g wet wt vs (0.51±0.06) mg/g wet wt, P=0.008, baseline (0.91±0.09) mg/g wet wt. Nearly normal ultrastructure of the graft was maintained in HGF group, atrophied microvilli and broken mitochondrial crista were observed in control group.ConclusionHepatocyte growth factor can improve mucosal structure, preserve enterocyte ultrastructure of isograft after small bowel transplantation in rat.

Methods The clinical data of 50 patients with pancreatolithiasis from January 2000 to January 2009 were retrospectively analyzed. Among them, there were 37 males and 13 females aged between 36 and 70 averaging at 49.3. The course of the diseases ranged from 7 days to 10 years with an average time period of 6.8 years. Forty-six patients had intermittent pain in the median abdomen and left upper quadrant combined by ectopic pain in the back. Various image examinations including abdomen ultrasonography, CT scan, and magnetic resonance cholangiopancreatography (MRCP) were performed in 50, 50, and 27 patients, respectively. Pancreatic duct stones were found in 45 of 50 cases (90％) with ultrasonograhy, 48 of 50 cases (96%) with CT scan, and 25 of 27 cases (92.5%) with MRCP. All patients received surgeries including 8 cases of pancreatodudenectomy, 42 cases of pancreatolithotomy plus side to side pancreatojejunostomy. At the same time, there were 12 cases of cholecystectomy, 6 cases of sphincterotomy and T-duct drainage, and 2 cases of Roux-Y anastomosis. Results Pancreatic duct stones were successfully removed in all cases, and the size of the stones ranged from 0.2 to 2.0 cm in diameter. The number of stones removed from each patient ranged from 1 to 50. Symptoms of all patients ameliorated obviously. One patient had incision infection after surgery, and recovered through active antibiotic treatment. Forty-six patients were cured and discharged from the hospital; 2 patients had their conditions improved and were discharged from the hospital; and the other 2 patients died of postoperative complications. Forty patients were followed up for 1 to 48 months with an average time of 24 months. During the follow-up, 2 patients with pancreatolithiasis and carcinoma of head of pancreas died of the recurrence of the cancer. Eight patients had recurrence of pancreatic stones and were cured after a second operation. Among the 8 cured patients, 2 still had abdominal pain, but their conditions were greatly improved after surgery. Conclusion Imaging techniques are important methods in diagnosing pancreatolithiasis with a high precision. Once the diagnosis of pancreatolithiasis is made, surgical procedures should be selected according to the combined diseases and the level of pancreatic duct dilation.
