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 sum up the measures for nursing the patients with laparoscopic gastrectomy-induced anastomotic leakage treated by open center vacuum aspiration. Method We retrospectively reviewed the histories of 22 patients with laparoscopic gastrectomy-induced anastomotic leakage to look into the nursing measures to look into the management of open vacuum aspiration , observation of the drainage, leakage care, mental care. Results The time for open center vacuum aspiration was between 10 to 17 days, averaged (15.63 ± 3.22)d. The hospital stay was between 13 to 23 days, averaged (17.21 ± 5.47)d. No complications were observed. Conclusions The nursing measures for managing the anastomotic leakage can be effective in improving the effect of peritoneal irrigation. The mental care can be effective for the reduction of patients′pains so as to promote the heal of the leakages.

Objective To investigate the effects of reactive oxygen species (ROS) inhibition on the down-regulation of adiponectin (ADPN) in mouse 3T3-L1 adipocytes by advanced glycation end-products (AGEs).Methods AGEs were prepared for incubating with cell.3T3-L1 preadipocytes were cultured in vitro and differentiated into mature adipocytes.Cell differentiation and lipid accumulation were determined by oil red O staining.After being intervened with AGEs,2',7'-dichlorofluorescein diacetate (DCFH-DA) was used as a reactive oxygen species (ROS) capture agent and the fluorescent intensity of 2',7 '-dichlorofluorescein (DCF) was detected by flow cytometry.Adiponectin expression under AGEs in 3T3-L1 adipocytes pretreated with N-acetyl-L-cysteine(NAC) or not was detected by real-time fluorescent PCR and ELISA.Results The level of ROS in 3T3-L1 adipocytes treated with AGEs was increased.mRNA and protein of ADPN were down-regulated.After inhibition with ROS,mRNA and protein expressions of ADPN injured by AGEs were ameliorated.Conclusion Exposure of 3T3-L1 adipocytes to AGEs induces oxidative stress in vitro,which decreases the expression of ADPN,and causes functional impairment of adipose cells and insulin resistance.

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

Objective To understand the present situation of safety organizing and quality of nurse work life in pediatric intensive care unit(PICU),and to discuss the relationship between safety organizing and quality of nurse work life.Methods A total of 279 PICU nurses in eight hospitals in Zhejiang were selected by the safety organizing scale (SOS)and quality of nursing work life(QNWL).Results The score of SOS was (45.23 ±10.88)points,and the score of QNWL was (159.46 ±33.60)points.There was a positive correlation between safety organizing and quality of nurse work life(r =0.256,P <0.05).Conclusion The nurse managers should improve the level of quality of nurse work life by safety organizing.
