Endoscopic retrograde cholangiopancreatonraphy (ERCP) is the main treatment modality for common bile duct stone.Biliary hemorrhage easily occurred in patients suffering from cirrhosis during and after ERCP.From May 2012 to May 2016,8 cases diagnosed with cirrhosis and common bile duct stones who developed post-ERCP refractory biliary hemorrhage were treated with full-covered self-expanding removable metal stents (FCSERMS),including 5 cases with perioperative hemorrhage of ERCP and 3 cases with delayed onset of biliary hemorrhage post ERCP.All the patients were successfully implanted with FCSERMS.Seven patients had successful hemostasis,and the other one case with ineffective hemostasis was treated with interventional arterial embolization later.Four stents were removed within 4 weeks and one in 8 months after ERCP.No evidence of biliary hemorrhage,intestinal fistula and other complications was observed during removal procedures.Spontaneous stent dislodgment occurred in one patient in postoperative 4 weeks,one patient died of liver failure in postoperative 6 months and one patient carried FCSERMS for 23 months.

The clinical data of 7 patients who underwent the treatment of gradual and persistent balloon dilatation (GPBD) by percutaneous transhepatic cholangiography (PTC)for traumatic biliary stricture in Zhongshan Hospital Affiliated to Dalian University were analyzed retrospectively.Balloon catheters were successfully implanted in 5 cases by PTC,and with the help of ERCP in 2 PTC failed cases.There was no bleeding,acute pancreatitis and other complications.Two balloon catheters were damaged and displaced,respectively.All the biliary strictures were relieved.No biliary sludge was attached on the surface of the balloon and in the bile duct.Bile duct mucosa had congestion edema and cellulose attachment.There was no biliary stricture recurrence in the follow-up of 5 to 27 months.This study showed GPBD by PTC was a simple,safe and effective method for treating traumatic biliary strictures.

Objective To evaluate endoscopic pancreaticobiliary separation (EPBS) in patients with gallstone and occult pancreaticobiliary reflux (OPBR).Methods The clinical data of 47 cases with gallstone and OPBR from Oct 2013 to Oct 2016 was analyzed retrospectively.Results The mean gallbladder bile amylase (GBA) was (864 ± 575) U/L.40 cases have undergone the treatment of endoscopic retrograde cholangiopancreatography.26 cases were diagnosed as duodenal papillitis,16 cases as periampullary diverticula,14 cases as long nipple,5 cases as atrophic papilla,3 cases as ampulla stone and 2 cases as papillary tumor.9 were diagnosed as pancreaticobiliary maljunction in the 14 patients with long nipple.33 cases were performed with EPBS.GBA was tested in 16 cases,and the GBA of 15 cases returned to normal level.The difference of GBA was statistically significant [(1 161 ±764) U/L vs.(47 ± 17) U/L,(t =5.641,P ＜ 0.05)].Patients were followed up for 1 to 4 years,among 36 cases without cholecystectomy,there was no recurrence of cholecystolithiasis after EPBS in 27 cases,but 2 cases had recurrent gallstones in 9 cases without EPBS,and the difference of gallstone recurrence rate was statistically significant (x2 =21.340,P ＜ 0.05).Conclusions Pancreaticobiliary junction diseases is an important cause for gallstone formation and OPBR.EPBS can avoid pancreaticobiliary reflux and reduce the recurrence rate of gallstone after choledochoscopic lithotomy.

Objective To evaluate the commonly used consciousness scales according to longitudinal study on small-sample patients with minimally conscious state. Method Eleven patients with minimally consciousness, who were scanned using fMRI, were selected and scored by the commonly used consciousness scales in Wujing Hangzbeu Hospital. The 11 patients were classified into 2 groups according to the scores of CRS-R scale couple with the results of the fMRI study. The One-Way ANOVA method was used to analyze the inter-group difference of the commonly used consciousness scales and their subscales. Results Despite the communicative subscale of the CRS-R scales, other iterms lack of statistic significance in classification of the conscious state. Among the commonly used consciousness scales, the Wessex Head Injury Matrix (WHIM) scale presented the highest diagnostic value in consciousness state, whereas the Chinese Vegetative State Scale (CVSS) presented the lowest diagnostic value. Conclusions It indicated that the total scores of the consciousness scales and the scores of subscales of them presented poor diagnostic value in general, and big discrepancy of diagnostic value existed between the iterms of the scales by using objective tools.

Objective To explore the therapeutic effect of drinking water test combined with swallowing training on cerebral infarction patients with dysphagia.Methods A total of 68 cerebral infarction patients with dysphagia in our department were randomly divided into observation group and control group.The control group was given routine nursing,while the observation group was given drinking water test to guide diet,and systemic swallowing function training on the basis of the control group.The therapeutic effects,feeding conditions and VSD scale scores were compared after 1 month of intervention between the two groups.Results The drinking water test score in the observation group was lower than that in the control group,and the total effective rate of the swallowing function improvement was higher than that in the control group,the differences were statistically significant (P ＜ 0.05).The FOIS score in the observation group was higher,and the score of VSD scale was lower than that in the control group,the differences were statistically significant (P ＜ 0.05).Conclusion Drinking water test combined with swallowing training can effectively improve the swallowing function of patients with dysphagia after cerebral infarction,and is beneficial to the normal diet of the patients.

Methods A total of 892 patients,receiving endoscopic nasal biliary drainage in Affiliated Zhongshan Hospital of Dalian University from January 2014 to December 2015, were randomly divided into experiment group and control group. X-ray assisted nasal catheter extractor was used in the experiment group,and guide wire was used in the control group. The mean extracting number and operation time, the total success rate, one-time success rate, response to stimulation and the incidence of complications were compared between the two groups. Results There were 457 cases in the experiment group. The mean extracting number was 1.08±0.32,the mean operation time was 1.07±0.29 min,the total success rate was 100.00%(457/457)and one-time success rate was 93.65%(428/457). The stimulation degree score was 1.27±0.50 with 348 cases of mild response,96 cases of moderate response and 13 cases of severe response. The rate of adverse reaction was 15.54%(71/457)with 50 cases of nausea, 18 cases of vomiting and 3 cases of mucosal bleeding. There were 435 cases in control group. The mean extracting number was 1.68±0.61,the mean operation time was 1.75±0.53 min, the total success rate was 75.63%(329/435)and one-time success rate was 38.16%(166/435). The stimulation degree score was 1.59 ±0.62 with 210 cases of mild response,194 cases of moderate response and 31 cases of severe response. The rate of adverse reaction was 35.86%(156/435)with 87 cases of nausea,36 cases of vomiting,27 cases of mucosal bleeding,and 6 cases of nasal duct prolapsed for vomiting. There were significant differences in the mean extracting number, mean operation time, stimulation degree score and the adverse reaction rate between the two groups(all P<0.001). The total success rate and one-time success rate in the experiment group were higher than those in the control group(all P<0.001).Conclusion X-ray assisted nasal catheter extractor can improve the success rate of operation,shorten the operation time,reduce the stimulation degree and the rate of adverse reactions in nose biliary oronasal conversion.

Objective To investigate the clinical value,safety and efficacy of pancreatic stent in prevention of postoperative acute pancreatitis in patients with benign biliary stricture (BBS) treated by fullcovered self-expanding removable metal stents (FCSERMSs).Methods From Jan 2011 to Dec 2017,92 BBS patients who met the inclusion criteria were admitted and divided into pancreatic stent (PS) group and control group.The acute pancreatitis (AP) and hyperamylase (HP) after FCSERMS implantation and removal was observed.Results 55 cases in PS group and 37 cases in control group underwent successful FCSERMS implantation.The incidences of postoperative elevated amylase and HP had no significant differences between the two groups (23.6％ vs.32.4％,3.6％ vs.10.8％,all P ＞0.05).The incidences of postoperative AP and moderately elevated amylase had significant differences (0 vs.13.5％,20.0％ vs.8.1％,all P ＜ 0.05).The average placement time of FCSERMSs was 7.84 ± 1.22 months.The incidence of elevated amylase,AP,HP and moderately elevated amylase after the FCSERMS and PS removed had no statistical differences (3.6％ vs.14.3％,0vs.2.9％,0 vs.2.9％,3.6％vs.8.6％,all P＞0.05).Conclusion The placement of pancreatic stents in the treatment of BBS with FCSERMS is a simple,safe and effective method for the prevention of post-ERCP pancreatitis.

Objective To explore the influence of psychological nursing on anxiety and depression of patients with coronary heart disease (CHD).Methods 100 CHD patients treated in Ward of veteran cadres in the First Affiliated Hospital of Harbin Medical University from November 2015 to January. 2016 were selected and divided randomly into observation group and control group,each with 50 cases. Patients in the control group received routine CHD nursing,on the basis of which,corresponding psychological nursing was conducted to patients in the observation group. Before and after the intervention,evaluated by self-rating anxiety scale (SAS) and self-rating depression scale (SDS),anxiety and depression of patients in the two groups were compared.
