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.

BACKGROUND:Health has been paid more and more attention in modern society, the health of those special groups, such as the elderly and the disabled, should also be brought to the forefront. As fitness equipment is more and more popular in contemporary, our focus should be transferred to the use of fitness equipment for these special groups.
OBJECTIVE:To put forward the design strategy of fitness equipment control interface, for the special groups to use common fitness equipment comfortably and conveniently.
METHODS:Based on the research of existing fitness equipment control interface, according to the usage habits and cognitive awareness of special groups on control interface, a new design strategy has been put forward using the general design method and ergonomics.
RESULTS AND CONCLUSION:Based on the existing 45 kinds of exercise bikes, 84 kinds of running machines and 129 kinds of treadmil fitness equipments, we found that these equipments are designed for common users in the aspects of design and production process and control interface. Universal design is a design concept beyond the lack of capacity to meet the different needs of different populations, and designed products can reduce or even eliminate the difference in the ability of special populations and the general population in use. The new strategy makes design of fitness equipment control interface generalized and good man-machine interactive, which can meet the demand of the special groups and help them do fitness exercise to improve their health and body function.

Objective To investigate the emotional problem of attention deficit and hyperactivity disorder(ADHD).Methods(Seventy) ADHD children and 45 controls were evaluated with the screen for child anxiety related emotional disorders(SCARED) and depression self rating scale for children(DSRSC).Results Children with ADHD showed significantly higher somatization/panic,general(anxiety),separated anxiety,scholasstic phobia and anxiety total score,depression total score(all P

The abdominal visceral fat content in obese SD rats induced by high fat diet for 10 weeks was significantly higher than that in control group [(26±6 vs 13±3)g,P<0.01] ,along with increased CRP mRNA expression in abdominal visceral fat (0.901±0.085 vs O. 402±0.036, P<0.01). As compared with normal control group, in the high fat group the concentrations of CRP in portal vein [(743.8±95.8 vs 558.3 ±118.3) mg/L, P<0.01] and peripheral vein[(596.3±38.9 vs 485.8±30.2) mg/L,P<0. 05] were higher. The concentration of CRP in portal vein was significantly higher than that in peripheral vein in high fat diet group(P<0.01) ,but this was not evident in control group. These results suggest that the increased CRP expression in visceral adipose tissue may partially account for the elevation of serum CRP in obesity.

Objective To explore the impact of advanced glycation end-products ( AGEs) on matrix metalloproteinase 2 ( MMP-2) expression in cultivated INS-1 cells. Method INS-1 cells were cultivated and MMP-2 expression was analyzed. Glycated serum was prepared for incubating with INS-1 cell. Reactive oxygen species (ROS) was detected by flow cytometry. The intracelluar MMP-2 expression was analyzed by RT-PCR, realtime PCR and Western blot. The MMP-2 cDNA was expressed in cultivated INS-1 cells. Result The level of ROS treated with AGEs was significantly higher than that in the control( P<0.05 ) , and the levels of MMP-2 and its protein expressions turned out as well( P<0. 05). Conclusion The results suggest that MMP-2 was expressed in INS-1 cells. Increased MMP-2 expression in ?cells may be induced by AGEs, suggesting that MMP-2 might play an important role in oxidative stress-mediated islet injury.
