Objective To explore the effect of self efficacy combined with mobile health information service applied in pulmonary rehabilitation in residence in elderly patients with chronic obstructive pulmonary disease. Methods Sixty-eight elderly patients in stable situation were divided into the control group and the intervention group with 34 cases in each group accoridng to the random digit table. In the control group, the nursing intervention included health education and telephone follow-up. The intervention group adopted self efficacy theory combined with mobile health information service. The items such as persistence in pulmonary rehabilitation, Exercise Self-Regulatory Efficacy Scale (Ex-SRES) and health condition were assessed. Results After intervention for 12 weeks, the scores of persistence in pulmonary rehabilitation in residence in the intervention group scored 5.35 ±1.42, which was higher than that in the control group (2.03±1.40), the difference was significant (t=160.43, P<0.01). Ex-SRES of the intervention group scored 62.06±13.10,91.21±11.12, which were higher than those of the control group, 50.38±18.03,42.56±18.23, the difference was significant (t=9.32,176.88, P<0.01) . The interaction between treatment effects and time effect was significant in COPD Assessment of Tool (CAT) and Ex-SRES respectively(F=489.95,P=0.00;F=134.80, P=0.00). Comparing value of CAT in baseline (24.97±4.74,24.62±5.39) and at the end of the twelfth week(24.94±4.74,24.65±5.35), the difference was not significant in two groups respectively(P>0.05). The improvement of CAT was significant at the end of the twenty-forth week (21.90±4.67) in the intervention group (t=-12.09, P<0.01). Conclusions Self efficacy theory and the application of mobile health information services can help patients persist in long-term rehabilitation exercise training.

Objective To explore the diagnosis,treatment,risk factors and prognosis factors of postpancreaticoduodenectomy hemorrhage (PPH).Methods The retrospective case-control study was adopted.The clinical data of 703 patients who underwent pancreatoduodenectomy at Hospital 401 of the People's Liberation Army from January 2008 to July 2013 were collected.Standard pancreatoduodenectomy was carried out for the malignant tumors of the head of pancreas or ampulla,pylorus-preserving pancreatoduodenectomy was operated for the benign tumor or the duodenal papilla tumor.The corresponding treatment was adopted for PPH.The observation indicators included:(1) the surgical situation (surgical method,operation time and the volume of intraoperative blood loss),(2) diagnosis of PPH,(3) treatment of PPH,(4) univariate and multivariate analyses for the risk factors affecting the occurrence of PPH,(5) univariate and multivariate analyses for the risk factors affecting prognosis of PPH patients.The measurement data with normal distribution were represented as x ± s.The measurement data with skewed distribution were represented as M (range).The chi-square test or Fisher exact probability was used for univariate analysis.Logistic regression model was used for multivariate analysis.Results (1) The surgical situation:among 703 patients,409 patients underwent standard pancreatoduodenectomy and 294 underwent pylorus-preserving pancreatoduodenectomy,including 1 combined with right hemihepatectomy,27 with portal vein reconstruction and 2 with hepatic artery reconstruction.Pancreaticojejunostomy was applied to 658 patients using mucosa anastomosis of the pancreatic duct to jejunum and 45 patients using invagination anastomosis.Supporting tube was routinely deposed in the pancreatic duct,598 patients had internal drainage and 105 patients had external drainage.The end-to-side anastomosis between common bile duct and jejunum was used for choledochojejunostomy.The 409 patients received the gastrojejunostomy using side-to-side anastomosis of gastric part and jejunum and 294 patients using end-to-side anastomosis of duodenum and jejunum.Operation time and volume of intraoperative blood loss were (324 ± 54) minutes and (428 ± 118) mL.(2) The diagnosis of PPH:among 703 patients after pancreatoduodenectomy,62 patients had PPH,the hemorrhage reasons of 38 patients had been identified,and the hemorrhage reasons of 24 patients had not been identified (A level in 5 patients,B level in 17 patients,C level in 2 patients).① The site of hemorrhage:the hemorrhage outside the cavity were detect in 27 patients,the hemorrhage inside the cavity in 28 patients,and the hemorrhage from both outside and inside part of the cavity in 7 patients.② The time of hemorrhage:early-stage hemorrhage were detected in 5 patients and the delayed hemorrhage in 57 patients.③The volume of postoperative blood loss was (885 ± 253)mL,30 patients had mild hemorrhage and 32 patients had severe hemorrhage.④ The clinical classification of PPH:5,32 and 25 patients were detected in level A,B,C,and 19 patients combined with sentinel hemorrhage.(3) The treatment of PPH:①5 patients with PPH in A level were given clinical observation,blood volume supplement and other treatment,then the symptoms gradually turned better.② Among 32 patients with PPH in B level,15 patients became better after symptomatic and supportive treatments,6 patients received successful hemostasis after guglielmi detachable colis embolization,4 patients received successful hemostasis under gastroscopic hemostasis,7 patients received emergency exploratory laparotomy.Thirty-two patients were improved and then out of hospital after treatment,without occurrence of death.③ Among 25 patients with PPH in C level,4 patients received successful hemostasis after guglielmi detachable colis embolization,17 patients received hemostasis by emergency exploratory laparotomy,4 patients with undiscovered bleeding points received the treatment of fluid infusion,blood volume supplement and antacid.Among 25 patients after corresponding treatment,10 patients were improved and 15 patients were dead.(4) The result of univariate analysis showed that the combined hypertension,vascular resection and reconstruction,postoperative pancreatic leakage and postoperative intraabdominal infection were risk factors affecting the occurrence of PPH (x2 =4.950,5.300,7.568,5.505,P ＜ 0.05).The results of multivariate analysis showed that the combined pancreatic leakage and postoperative intraabdominal infection were independent risk factors affecting the occurrence of PPH [OR =2.761,2.216,95％ confidence interval (CI):1.389-5.489,1.198-4.101,P ＜ 0.05].(5) The risk factors affecting the prognosis of PPH patients:the results of univariate analysis showed that postoperative sentinel hemorrhage,postoperative pancreatic leakage,site,degree and level of hemorrhage were risk factors affecting the prognosis of PPH patients (x2 =8.022,4.448,11.853,18.551,28.285,P ＜ 0.05).The results of multivariate analysis showed that postoperative sentinel hemorrhage and site of hemorrhage (outside and inside part of the cavity) were independent risk factors affecting the prognosis of PPH patients (OR =5.550,0.233,95％ CI:1.595-19.314,0.086-0.635,P ＜ 0.05).Conclusions Pancreatic leakage and intraabdominal infection are independent risk factors after pancreatoduodenectomy.The treatment effect of the early-stage hemorrhage is better than that of the delayed hemorrhage,and angiographic embolization is the first choice of diagnosis and treatment for the delayed hemorrhage.Sentinel hemorrhage could result from aneurysm or continuous arterial hemorrhage of vascular erosion,it is the independent risk factor affecting the death of hemorrhage after pancreatoduodenectomy.

Objective To apply short message service (SMS) for pulmonary rehabilitation in residence. Methods A total of 102 old pa-tients with chronic obstructive pulmonary disease (COPD) in stable situation were equally divided into three groups randomly. They all ac-cepted a two-week lesson of exercise project, and then took in the project for 22 weeks. Meanwhile, group A phoned to their experts once a week, group B was phoned by their experts once a week, and group C accepted SMS once a day and sent back to the experts. They were in-vestigated with Exercise Self Regulatory Efficacy Scale (Ex-SERS), modified British Medical Research Council Scale (mMRC) and COPD Assessment Test (CAT) before and after intervention. Results The score of Ex-SERS was the most in group C (F=179.53, P<0.001), with the interaction of time (F=387.09, P<0.001). While the scores of mMRC (F=8.754, P<0.001) and CAT (F=11.32, P<0.001) were the least in group C. Conclusion Application of SMS in the integrated management for pulmonary rehabilitation in residence may improve the self regu-latory efficacy of exercise, release the dyspnea and the influence on living in patients with COPD.

Objective To compare the short‐term clinical effects of single segment and two segments of Dynesys dynamic in‐ternal fixation system for treating lumbar degenerative disease .Methods 40 cases of degenerative lumbar disease treated by the Dynesys dynamic fixation system combined with posterior approach decompression from 2009 July to March 2012 were selected and performed the evaluation on the clinical effects by the waist and leg pain visual analogue scale (VAS) ,the Oswestry disability index (ODI) and the orthopaedic spinal association of North America (NASS) index .The imaging method was used to observe the mobili‐ty of operative segment and proximal adjacent segment and the degenerative change of intervertebral height .Results All of the 40 cases were followed up .The VAS score and ODI score at postoperative 3 months and last follow‐up were significantly decreased when compared with the pre‐operative scores (P<0 .05);there was no statistically significant differences in the VAS score and ODI score at 3 months and last follow‐up between the single segment group and the 2‐segment group (P> 0 .05) .The NASS index showed no statistically significant difference in the postoperative effect satisfaction between the two groups (P>0 .05);there was no statistically significant difference in the variation of the intervertebral height between before operation and at the last follow‐up (P>0 .05) .There was statistically significant difference in the motility of proximal adjacent segment at the last follow‐up between the two groups (P<0 .05);but comparing the motility of proximal adjacent segment between the last follow‐up and pre‐operation , only the single segment group showed statistically significant difference (P< 0 .05) .Conclusion The Dynesys dynamic fixation system combined with posterior approach decompression operation has good clinical effect in the treatment of lumbar degenerative disease .Meanwhile ,the single segment method has more significant effect on the motility of proximal adjacent segment than the double segments method .

Objective To investigate the alterations in killer cell immunoglobulin-like receptors (KIRs)2D and their specific HLA-Cw ligands in patients with ankylosing spondylitis(AS)and determine whether the changes were correlate to the pathogenesis of AS.Methods Polymerase chain reaction of sequence specific primerB(PCR-SSP)was employed for genotyping the presence or absence of five KIR2D genes(KIR2DL1,2DS1,KIR2DL2,2DL3,2DS2)as well as HLA-Cw01-08 alleles from genomic DNA in 105 individuals with AS,together with 51 individuals with osteoarthritis(OA)and 120 healthy controls.Then HLA-C10-08 was divided into two groups.HLA-Cwasn and HLA-Cwlys to calculate the frequency of KIRID genotype.HLA-Gu alleles and KIR/HLA-Cw genotypes.Results The frequencies of HLA-Cwlys genes were significandy higher in patients with AS(0.269 7)compared with those in OA controls(0.148 2)and healthy controls(0.138 8,P=0.024,P=0.001,respectively).The frequency of KIR2DS1/HLA-Cwlys combination Was also markedly higher in AS group(26.67%)than that in OA controls(11.76%)and healthy controls(13.33%,P=0.039,P=0.018,respectively).Condusion The data suggest that the HLA-Cwlys allele may be associated with genetic susceptibility to AS and moreover.in the existence of HLA-Cwlys.the individuals with KIR2DS1 gene are likely to be at increased risk of AS.

Objective To explore the risk and treatment of laparoscopic cholecystectomy(LC) in patients with liver cirrhosis and cholelithiasis.Methods To summarize the clinical data of 28 patients with liver cirrhosis and cholelithiasis.The patients were repeated right upper quadrant pain,including 4 cases of gallbladder neck stones incarcerated,gallbladder effusion.Among them,there were 20 cases of hepatitis B cirrhosis,5 cases of schistosomiasis cirrhosis,3 cases of alcohol.Results There were 6 patients with hemorrhage during operation.Among them,5 patients were treated with gelatin sponge,hemostatic gauze and bio-glue spray to stop bleeding,1 case was transferred to open surgery because of bleeding.The remaining 27 cases of LC were successful.Complications occurred in 8 patients,3 cases of increased liver function abnormalities,1 case of upper gastrointestinal bleeding,1 case of mild hepatic encephalopathy,2 cases of significant ascites formation,1 patient underwent subtotal resection of the gallbladder with Hartmanns bag,and bile was found in the ascites after surgery,but the bile disappeared after five days.All patients with complications after symptomatic treatment were cured,no death,no major bleeding and liver failure,bile duct injury,severe biliary fistula and other serious complications.Conclusion Although the risk of LC in patients with liver cirrhosis is higher than that in the general population,with the help of current high-tech surgical instruments,we can safely accomplish this with an improved surgical procedure.As these patients require high technical requirements of surgery,surgeons must have a wealth of experience and familiar laparoscopic liver and gallbladder anatomy.

In this paper, a new method was presented which can generate dental panoramic radiographs from the 3D CT sectional data. The dental panoramic radiograph was generated by casting ray into the 3D sectional data from a curved surface close to the dental arch. With this method, the relationship between the 3D CT sectional data and the dental panoramic radiographs was built, which helped to overcome the defects in the real X-ray panoramic radiographs, such as structure overlap and unselectable content for displaying. The technology is of certain significance in computer aided technique and surgical planning related to dentistry.
