Conclusion HIFU is effective and safe for the treatment of mid-late stage liver cancer.
Objective To investigate the early diagnosis and treatment methods of primary duodenal papilla carcinoma. Methods The medical records of 54 patients with primary duodenal papilla adenocarcinoma underwent operation between January 2002 and December 2008 were reviewed. Results Thirty seven cases received fiberduodenoscopy and 35 cases received ERCP, and the accuracy of them were both 100%. Forty four patients received duodenopancreatectomy and 10 patients received jaundice-reducing operation. The 1-, 3-, and 5-year cumulation survival rate was 68%, 50%, and 29%, respectively. Conclusions Fiberduodenoscopy and ERCP are the effective diagnostic methods for duodenal papilla carcinoma. Early diagnosis and early rational radical operation are essential for successful treatment of duodenal papilla carcinoma.
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 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.
Objective To evaluate the efficacy and safety of tetramethylpyrazine (TMP) for diabetic peripheral neuropathy (DPN). Methods Randomized controlled trials were identified from CBM (1978-2003.3), TCMLRS (1980-2003.3), Medline (1970-2003.3), EMbase (1970-2003.3) and Cochrane Library (issue 3, 2003). We handsearched Journal of Traditional Chinese Medicine (1990-2002), New Chinese Medicine (1990-2002), Chinese Journal of Integrated Traditional and Western Medicine (1990-2002) and Research of Traditional Chinese Medicine (1990-2002). Papers of the controlled trials of clinical therapeutic studies on DPN treatment by Chinese medicine herb TMP were included and analyzed according to the criteria of the Cochrane Handbook in 1997. Results Six RCTs involving 669 patients were included, with all trials of low methodological quality. Meta-analysis indicated TMP was more effective than western medicine on pain or numbness of extremities of DPN [The pooled OR = 10.12, 95%CI (6.70 to15.28), P=0.000] and motor nerve conduction velocity change of common peroneal nerves and median nerves . Only one trial reported the side effects of TMP, such as dizziness and headache. Conclusions Based on the review, TMP infusion may have positive effect on DPN. However, the evidence is not b enough due to the general low methodological quality, so we can’t draw a reliable conclusion about the effects of TMP for DPN at the moment. Further large randomized, double blind, placebo-controlled trial are needed.
Objective To evaluate the therapeutic efficacy and safety of trazodone versus alprazolam for generalized anxiety disorder (GAD). Methods After the third day of a three-day screening period, 60 patients with generalized anxiety disorder were randomly assigned to the trazodone group (30 patients, 50-150 mg/d), and alprazolam group (30 patients 1.2-4 mg/d) for 4 weeks. Patients and their doctors were blind. Data were analyzed by SPSS 10.0 and intention-to-treat analysis. Results The total effective rate of trazodone was 77% (23/30), while alprazolam was 70% (21/30) (Pgt;0.05) .No difference was seen for adverse events. None was lost to follow in the two groups. Conclusions Trazodone appears to be as effective as alprazolam in treating generalized anxiety disorder. Adverse events may include confusion and loss of appetite, but patients are able to tolerate these.

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.
