Objective To investigate the effects of tirofiban combined with nitroprusside injection through the rapid exchange balloon catheter with self-made side holes on no-reflow (NR)phenomenon during elective percutaneous coronary intervention (PCI).Methods A total of 49 patients with NR phenomenon were randomly divided into the balloon catheter group (n=25)and the guiding catheter group (n=24).Tirofiban combined with nitroprusside were used in both groups.Thrombolysis in myocardial infarction (TIMI)grade and corrected TIMI frame count (CTFC)of target coronary artery at 10 minutes after administration were assessed.Results At 10 minutes after drugs injection,there were 21 (84.0%)patients with target of coronary TIMI 3 grade in the balloon catheter group,and 13 (54.2%)patients in the guiding catheter group.The CTFC was (33.5±12.5)frame in the balloon catheter group,and (41.9±1 5.3)frame in the guiding catheter group.The difference in TIMI and CTFC between the two groups was significantly (P <0.05).Conclusion Injection tirofiban combined with nitroprusside through the rapid exchange balloon cathe-ter with self-made side holes in NR patients during elective PCI might be feasible and effective.

Aimed at tackling the compatibility issues arising from the drug reaction in intravenous infusion tube, we developed a simple, suitable and multi-function intravenous infusion tube for the special use for rescuing critical patients, the elderly, children etc. Each drug in a transfusion process can be filtered to realize quantitative packet and packet delivery. Thus, the drugs in the infusion tube are prevented from meeting with each other. No overlap, no particle pollution occurred. Stable performance and accurate dosage are maintained. As a result safety is ensured during drug delivery.

Objective To investigate the correlation between single nucleotide polymorphisms (SNP) of gene interleukin-23 receptor (IL-23R) rs1004819, rs1495965, rs1884444, rs2201841,rs6677188, rs7517847, rs7530511, rs10489629, rs10889677 and rs11209026 with susceptibility of inflammatory bowel disease (IBD) in Han population of Jiangsu province in China. Methods The gene polymorphism in 134 healthy volunteers, 135 cases of ulcerative colitis(UC) and 43 cases of Crohn's disease(CD) were detected with SNaPshot. Experimental data were analyzed with SPSS 17.0 software. Results In UC, genotype frequency of CC and CT on rs7530511 was 99.26％ (134/135)and 0.74％(1/135), allele frequency of C and T was 99.63％(269/270)and 0. 37％(1/270). While in normal controls, which were 94.03％(126/134), 5.97％(8/134), 97.01 ％(260/268)and 2.99％(8/268)respectively. Compared genotype frequency of these two group, P value was 0. 040 (OR＝0.118、95％CI:0.014～0.953). Compared allele frequency of these two group, P value was 0. 043 (OR＝0.121、95％CI:0.015～0.973). In wild type and mutation type UC patients, the age distribution was different, more young patients in mutation type while more middle-aged patients in wild type, P value was 0.032 and 0.001 respectively. Most UC patients of rs6677188 AT type were in remission under endoscope (P＝0.032). Conclusion The mutation of IL-23R rs7530511 may be a protective factor of UC. The polymorphism of rs6677188 was associated with the age of patients and the remission under endoscope.

Objective To compare the short- and long- term effects and safety of endoscopic balloon dilatation vs. placement of specially designed reclaimable self-expanding anti-reflux esophageal stents for achalasia. Methods A total of 129 patients with achalasia were divided into 2 groups to receive either endoscopic scopic balloon dilatation(,l=63)or endoscopic placement of specially designed reclaimable self-expandinganti-reflux esophageal stents (n = 66). The dysphagia symptom scores were recorded before and 1-month,6-month and 12-month after the procedure, respectively. The change in width of esophagus, procedure related complications, length and costs of hospitalization were also analyzed. Results Dysphagia symptom score was significantly decreased after the treatment in both groups (P < 0.05). The effective rates evaluated at 1-month, 6-month and 12-month after the procedure in balloon dilatation group were 100. 0% , 96. 7% and 91.5% , respectively, which in stenting group were 100.0% , 98. 0% and 97.1% , respectively. There was no significant difference in changes of symptom score at 1-month and 6-month after treatment between the 2 groups (P > 0.05) , while at 12-month after treatment, the decrease of symptom score in stenting group was significantly higher than that in balloon dilatation group (P<0. 05). After the treatment, the significant widening of the stricture and narrowing of the dilated esophagus were achieve in both groups (P < 0.05),while no significant difference between these 2 groups was observed in changes of width (P > 0. 05). Procedure related complications in balloon dilatation group included esophageal perforation (n =1) and upper gastrointestinal bleeding (n=4) , which was not occurred in stenting group, but complications included hyperplasia of granulation tissue (n = 1), stent dislocation (n =2) and defulvium (n = 1) was observed inthe latter group. The length of hospitalization was similar in 2 groups (P > 0. 05) , and the cost of hospitalization in stenting group was significantly higher than that of balloon dilatation group (P < 0. 05). Conclusion Compared with endoscopic balloon dilatation, the specially designed reclaimable self-expanding antireflux stents is a more ideal method for achalasia, with similar short-term effect, but better long-term effect and safety.

OBJECTIVETo compare the expression patterns of cytokeratin 7 (CK7) and CK20 in the Barrett's esophagus and gastric cardia intestinal metaplasia.

METHODSEndoscopic biopsy specimens from 19 patients with long segment Barrett's esophagus, 36 with short segment Barrett's esophagus, and 20 with histological evidence of gastric cardia intestinal metaplasia were immunostained for CK7 and CK20. The immunohistochemical data were analyzed in relation with the clinicopathological data of the patients including age, hiatal hernia, and Helicobacter pylori status.

RESULTSThe Barrett's pattern of CK7/20 expressions was found in all the 19 patients with long segment Barrett's esophagus, in 31 of the 36 (82%) patients with short segment Barrett's esophagus, and in 2 of the 20 (10%) patients with gastric cardia intestinal metaplasia. Patients with short segment Barrett's esophagus who had a Barrett's CK7/20 pattern showed similar clinicopathological findings to those with long segment Barrett's esophagus, while in cases of short segment Barrett's esophagus where no Barrett's CK7/20 pattern was found, the clinicopathological features were similar to those of gastric cardia intestinal metaplasia cases.

CONCLUSIONA Barrett's CK7/20 expression pattern is an objective marker of Barrett's mucosa. CK7 and CK20 reactivity patterns in routine endoscopic biopsy samples can reliably identify the location of intestinal metaplasia in the esophagus and stomach.
