Methods Between January 2007 and January 2009, 178 chronic hepatitis B patients with positive HBeAg were randomly divided into two groups: the treatment group (91 cases) and the control group (87 cases). All patients in two groups received 10 mg of ADV once a day for 104 weeks, while the patients in the treatment group received 1 mg of thymopentin for subcutaneous injection every other day for 52 weeks. The rates of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) normalization, serum hepatitis B virus (HBV) DNA clearance and HBeAg loss and anti- HBeAg seroconversion were evaluated at pretreatment, and 52, 104 and 156 weeks after treatment, respectively. Results After 52-week treatment, The rates of ALT and AST normalization, serum HBV DNA clearance and HBeAg loss and anti- HBeAg seroconversion in the treatment group were higher than those in the control group. In 52-week follow-up after 104 weeks treatment, the rates of ALT and AST normalization , serum HBV DNA clearance and HBeAg loss and anti- HBeAg seroconversion of two groups were 74.73% versus 51.72%, 75.82% versus 54.02%, 25.27% versus 8.05%, 26.37% versus 10.34%, 18.68% versus 8.05%, respectively (χ2 = 10.652, 9.313, 9.421, 7.574, 4.313; P<0.05). Conclusions It is more effective for adefovir dipivoxil combined with thymopentin on HBeAg-positive patients with chronic hepatitis B than using adefovir alone. Combination treatment could improve the rates of HBeAg seroconversion and reduce the breakthrough of HBV after drug withdrawal. And it is safe.

  • Study on Relationship Between RasTG and Pancreatic Carcinoma

    ObjectiveTo study the expressions of Ras trapping to Golgi (RasTG) genes in pancreatic carcinoma tissues and to observe the growth, proliferation and the impact of tumors formation of human pancreatic cancer cells (PANC-1), and to explore its mechanism. MethodsMade PANC1 as a target to research, transfected RasTG genes into PANC-1, used RNAi technology and observed the growth, proliferation and the impact of tumors formation of the cells. Meantime, contrasted the RasTG expressions between pancreatic ductal cancer and adjacent tissue by tissue microarray technology. Results①The expression of RasTG gene in tissues was not very differential, which was higher in the brain, liver, and adrenal gland. ②The expression of RasTG protein in pancreatic ductal carcinoma was significantly higher than that in adjacent tissues (Plt;0.05). ③After RasTG RNAi in PANC-1 cells, the ability of growth and proliferation were decreased. ④The ability of tumors formation in PANC-1 cells after RNAi was decreased, carcinoma’s volume of transfected group was significantly smaller than that in the nontransfected group (Plt;0.05). ConclusionsRasTG gene is widely distributed in animals. RasTG protein in pancreatic carcinoma tissues is higher than that in adjacent tissues. The ability of proliferation, transformation and tumors formation in PANC-1 cells after RNAi of RasTG gene are restrained, RasTG gene is a positive regulatory factor.

  • Analysis on Clinical Efficacy of Frey Procedure for Chronic Pancreatitis

    ObjectiveTo explore clinical efficacy of Frey procedures for chronic pancreatitis. MethodsThirty two patients with chronic pancreatitis who underwent Frey procedures in our hospital from June 2000 to October 2009 were analyzed retrospectively. The rate of perioperative complications, pain relief, and especially endocrine and exocrine function of pancreas in longterm followup (mean 43 months) were analyzed. ResultsNo death occurred in all patients. Fat liquefaction of wound was found in two patients and pancreatic fistula was found in one patient, who was cured by conventional treatment. So the rate of perioperative complications was 9.4%(3/32). After Frey procedures, pain disappeared completely in sixteen patients (50.0%), pain relieved in fourteen patients (43.8%) and two cases were ineffective. Therefore, the rate of pain relief in longterm follow-up was 93.8%. The hospitalization was (11±2) d. After surgical treatment the illness of five patients with diabetes mellitus did not aggravate while new onset of diabetes mellitus was observed in three cases. For three cases who suffered from indigestion and steatorrhea, symptomatic relief was found in one patient treated by oral administration of pancreatin and inefficacy was observed in two cases. But four patients with new steatorrhea were found after operation. ConclusionUnder the strict surgical indications, Frey procedure is a safe and effective surgical method for the treatment of chronic pancreatitis.

  • Clinical Application of Beger Procedure and Frey Procedure for Benign Disease or Low-Grade Malignant Potential Lesion of Pancreas

    ObjectiveTo review the current clinical application of Beger procedure and Frey procedure for benign disease or low-grade malignant potential lesion of pancreas. MethodsRelevant literatures about current advance of clinical application of Beger procedure and Frey procedure published recently of domestic and abroad were collected and reviewed. ResultsWith the concept of organ-preserving operations was adopted in recent years, Beger procedure and Frey procedure were applied generally. Beger procedure and Frey procedure were associated with tolerable perioperative risk, postoperative complications, and good outcomes in the aspects of preservation of function and curability in these lesions compared to conventional pancreatectomy, with preservation of the physiological food passage, thus patients gained weight faster, had less pain, and demonstrated better exocrine and endocrine pancreatic function postoperatively and an improvement in the quality of life. Both procedures had reached an international position as a standard operation for the treatment of benign disease or low-grade malignant potential lesion of pancreas. But after long-term following-up early advantages were no longer present. ConclusionsBeger procedure and Frey procedure are safe and effective in providing good outcomes in the aspects of preservation of function and curability in benign disease or low-grade malignant potential lesion of pancreas. Organ-preserving pancreatectomy could become a new organ-preserving standard operation.
