Aberrant promoter methylation in special genes such as tumor suppressor genes is early eventin carcinogenesis of lung cancer. Aberrant methylation, resulting in corresponding mRNA silence or overexpression , closely relates to carcinogenesis, development, treatment response and prognosis of lung cancer and it may become a potential biomarker. Methylation of special genes may provide evidences for individual treatment of lung cancers.

Objective To explore the application of plastic pancreatic stents and/or nasal biliary drainage for choledocholithiasis patients having DSBC during Endoscopic Retrograde Cholangiopancreatography (ERCP).Methods Retrospective analysis on clinical data of 57 ERCP cases aiming at choledocholithiasis patients having DSBC from January 2010 to December 2015 has been carried out. According to the guide wire cannulation in an operation, patients are divided into three groups, i.e. plastic pancreatic stents group, nasal biliary drainage group, and plastic pancreatic stents + nasal biliary drainage group, so as to observe the success rate of operation and the occurrence rate of postoperative complications, such as pancreatitis or hyperamylasemia, as well as to compare the differences between the three groups.Results Out of the 57 patients receiving ERCP, 13 patients are in the plastic pancreatic stents group, with two successful operations (15.4%), one case of hyperamylasemia (7.7%), two cases of postoperative pancreatitis (15.4%), one case of fever (7.7%) and one case of hemorrhage (7.7%); 20 patients are in the nasal biliary drainage group, with 20 successful operations (100.0%), no occurrence of hyperamylasemia or postoperative pancreatitis or other complications including hemorrhage and fever; 24 patients are in the plastic pancreatic stents + nasal biliary drainage group, with 19 ERCP operations succeeded at the first attempt (79.2%) and 5 ERCP operations succeeded at the second try (20.8%), as well as 4 cases of hyperamylasemia (16.7%), 2 cases of hemorrhage (8.3%) , no occurrence of fever cases and postoperative pancreatitis. In comparison between the three groups, the occurrence of postoperative pancreatitis and successful rate of operation show a significant difference.Conclusion By adopting plastic pancreatic stents and/or nasal biliary drainage for patients having a dififcult selective biliary cannulation during ERCP, the success rate of operation can be improved, and the occurrence of pancreatitis can also be reduced.

Radiofrequency ablation (RFA) is one of the most important methods for the treatment of liver cancer and has the advantages of small trauma,simple operation,and repeatability.However,for tumors in high-risk locations within 5 mm of the first and second branches of the hepatic portal vein,near the hepatic vein,the inferior vena cava,or the gallbladder,within 5 mm of the intestinal tract,under the Glisson's capsule,and in the diaphragm,RFA has the issues of a low complete ablation rate,a high local recurrence rate,and serious complications.This article introduces the complications of RFA for liver cancer in high-risk locations and their prevention and points out that with the promotion of individualized and standardized RFA,liver cancer in these high-risk locations is no longer a contradiction for RFA.

Objective To solve the problem of hospital Bureau class cost accounting system to manage the Branch class cost. Methods The system was optimized by extracting the raw data of localization, collecting income and expenditure account of flexible specialization, and setting subclass accounting ratio ways of rationalization. Results The optimization subsystem has been a fundamental change in cost accounting management and creates more effective. Conclusion According to the special requirement of sanatorium financial process, information system and cost accounting ways, the new system can be optimized in design and implementation method and achieve better effects during the implementation and operation.

OBJECTIVE:To evaluate and compare the efficacy and safety between the chronomodulated chemotherapy of oxaliplatin combined with calcium folinate and tegafur and the normal chemotherapy in the treatment of advanced gastrointestinal cancer.METHODS:A total of 63 patients with advanced gastrointestinal cancer were randomly divided into two grou_ ps:31 in chronomodulated chemotherapy regimen group were assigned to receive oxaliplatin in combination with calcium folinate and tegafur,and another 32 in normal chemotherapy regimen group to receive oxaliplatin combined with calcium folinate and fluorouracil.2 courses of treatment later(21 days/course of treatment)the short-term effects and the adverse drug reactions(ADRs)of the 2 groups were evaluated.RESULTS:The effective rates of the chronomodulated chemotherapy group and the normal group were 77.4%and 43.8%(P

OBJECTIVETo discuss the mechanism of gambogenic acid (GNA) in inducing the apoptosis of melanoma B16 cells.
METHODThe inhibitory effect of GNA on the proliferation of B16 cells was measured by the methyl thiazolyl tetrazolium (MTT) assay. The effect of GNA on B16 cells was detected by the Hoechst 33258 staining. The transmission electron microscopy was used to observe the ultra-structure changes of B16 cells. The changes in PI3K, p-PI3K, Akt, p-Akt, p-mTOR, PTEN proteins were detected by the Western blotting to discuss the molecular mechanism of GNA in inducing the apoptosis of B16 cells.
RESULTGNA showed a significant inhibitory effect in the growth and proliferation of melanoma B16 cells. The cell viability remarkably decreased with the increase of GNA concentration and the extension of the action time. The results of the Hoechst 33258 staining showed that cells processed with GNA demonstrated apparent apoptotic characteristics. Under the transmission electron microscope, B16 cells, after being treated with GNA, showed obvious morphological changes of apoptosis. The Western blot showed a time-dependent reduction in the p-PI3K and p-Akt protein expressions, with no change in p-PI3K and p-Akt protein expression quantities. The p-mTOR protein expression decreased with the extension of time, where as the PTEN protein expression showed a time-dependent increase.
CONCLUSIONGNA could inhibit the proliferation of melanoma B16 cells and induce their apoptosis within certain time and concentration ranges. Its mechanism in inducing the cell apoptosis may be related to PI3K/Akt/mTOR signaling pathways.
