Risk assessment of cirrhosis patients with esophageal and gastric variceal bleeding by three scoring systems / 中华消化内镜杂志

Objective:To compare the risk assessment capability of model for end-stage liver disease (MELD), glasgow-blatchford score (GBS), and the AIMS65 scoring system for liver cirrhosis patients with esophageal and gastric variceal bleeding (EGVB).Methods:A retrospective analysis was made on data of 182 cirrhosis patients with EGVB admitted to the Department of Gastroenterology, General Hospital of Tianjin Medical University from January 1, 2015 to March 1, 2018. According to the MELD, GBS and AIMS65 scoring system, the corresponding scores of each patient were calculated to evaluate the ability of the three scoring systems to correctly classify EGVB as a " high-risk patient" . The receiver operating characteristic curve was drawn to compare the predictive value of three scoring systems for different clinical outcomes (blood transfusion, rebleeding, and death). The area under curve (AUC)>0.7 was believed to have higher accuracy.Results:The clinical outcomes of 182 patients included blood transfusion in 113 (62.1%) cases, rebleeding in 31 (17.0%) cases, and death of 11 (6.0%) cases. The MELD score was 7-25, GBS was 3-16, and AIMS65 score was 0-3. There were 4 (2.2%) patients with MELD score < 9, 139 (76.4%) patients with AIMS65 score 0-1, including 68 patients with AIMS65 score of 0 and 71 patients with AIMS65 score of 1. The AUC of MELD, GBS and AIMS65 for predicting blood transfusion was 0.514 (95% CI: 0.439-0.589), 0.681 (95% CI: 0.608-0.748), and 0.669 (95% CI: 0.596-0.737), respectively. When predicting rebleeding, the AUC of MELD, GBS and AIMS65 was 0.525 (95% CI: 0.449-0.599), 0.528 (95% CI: 0.453-0.602) and 0.580 (95% CI: 0.505-0.652), respectively. When predicting in-hospital mortality, the AUC of MELD, GBS and AIMS65 was 0.642 (95% CI: 0.567-0.711), 0.581 (95% CI: 0.505-0.653) and 0.786 (95% CI: 0.719-0.843), respectively. AIMS65 was superior to MELD ( P=0.083 6) and GBS ( P=0.047 0). Conclusion:GBS can correctly classify cirrhosis patients with EGVB as " high-risk group" , and is better than AIMS65 and MELD scoring system. MELD, GBS and AIMS65 all have poor accuracy in predicting blood transfusion and rebleeding, AIMS65 has a higher predictive value for death.

Application of four scoring systems on evaluation of the prognosis of acute nonvariceal upper gastrointestinal bleeding / 中华消化内镜杂志

Objective To evaluate the predictive value of Admission-Rockall Score (aRS), Full-Rockall Score ( fRS ), Glasgow-Blatchford Score ( GBS ) and AIMS65 scoring systems for rebleeding, mortality, transfusion and clinical intervention of patients with acute nonvariceal upper gastrointestinal bleeding ( ANVUGIB). Methods A retrospective study was performed on the data of 294 ANVUGIB inpatients in the Department of Gastroenterology of Tianjin Medical University General Hospital from January 2015 to September 2016. Each patient was graded using the four scoring systems. The area under the receiver-operating characteristic curve ( AUC) about rebleeding, mortality, blood transfusion and clinical intervention was calculated using each system. Results For predicting rebleeding, fRS (AUC＝0. 696) and GBS (AUC＝0. 697) were both superior to aRS (AUC＝0. 609, P＜0. 05) and AIMS65 (AUC＝0. 571, P＜0. 05), and there was no significant difference on AUC between fRS and GBS (P＞0. 05). For predicting mortality, the AUC of aRS, fRS, GBS and AIMS65 were 0. 755, 0. 791, 0. 818, and 0. 780, respectively, and there were no significant differences (P＞0. 05). There were no significant differences in the predicting transfusion among four scoring systems, and the AUC was 0. 625, 0. 626, 0. 697 and 0. 658, respectively. Regarding clinical intervention treatment, fRS (AUC＝0. 661) was superior than that of aRS (AUC＝0. 520, P＜0. 05) and AIMS65 (AUC＝0. 545, P＜0. 05), and the AUC of GBS and three other scoring systems had no significant differences (P＞0. 05). Conclusion The four scoring systems are all with good predicting value on mortality of patients with ANVUGIB, while not on other aspects including rebleeding, transfusion and clinical intervention. fRS has a slightly better value on prediction of rebleeding and clinical intervention, and GBS is slightly better on prediction of rebleeding.

Limitations of endoscopic ultrasonography in the diagnosis of esophageal submucosal tumor / 中华消化内镜杂志

Objective To investigate the diagnostic value of endoscopic ultrasonography(EUS)for esophageal submucosal tumor(SMT). Methods Clinical data of 388 patients with esophageal SMT, who underwent EUS and endoscopic treatment in Tianjin Medical University General Hospital were collected from May 2010 to September 2016. The golden standard for the origin of esophageal SMT was the diagnosis during endoscopic treatment, and the golden standard of pathological type was the combination of postoperative pathological and immunohistochemical findings. The diagnostic accuracy of EUS for esophageal SMT was evaluated. Results The conventional endoscopy revealed that 31.70%(123/388)and 43.81%(170/388)esophageal SMTs were located in the middle and lower segments of esophagus,respectively. The diagnostic consistency of EUS for the origin of lesion was 71.51%(251/351), while the diagnostic consistency of EUS for lesion originated from the muscularis mucosae, submucosa and muscularis propria layer was 92.90%(170/183), 34.38%(11/32), and 51.47%(70/136), respectively. The diagnostic consistency of EUS for the type of lesion was 81.00%(260/321), while the diagnostic consistency of leiomyoma, esophageal cyst, and lipoma were 88.42%(252/285), 14.81%(4/27), and 80.00%(4/5), respectively. Conclusion EUS can preliminarily diagnose the origin and pathological type of esophageal SMT,but there are limitations on the diagnosis of uncommon lesions,which need combination of pathological and immunohistochemical findings.

Objective To explore the necessity of colonoscopy in young patients with chronic constipation.Methods Data of patients aged 18-50 underwent colonoscopy at Tianjin Medical University General Hospital with chronic constipation as the sole indication between April 2003 and May 2014 were analyzed.Endoscopic and pathologic reports were analyzed.Results During the study period,a total of 563 patients were included,who were aged 18-50 with chronic constipation as the sole indication,of which 260 patients were aged 18-35,and 303 patients were aged 36-50.No lesion was found during colonoscopy in 167 (29.7％) patients,whereas in other 396 (70.3 ％) patients positive findings were reported,including polyps in 45 patients (of which 13 were with multiple polyps),adenomas in 20(17 in distal colon,3 in proximal colon).In patients aged 18-35,3 cases of adenomas(3/260,1.2％) were found,of which 1 patient (1/260,0.4％)had advanced adenoma.In patients aged 36-50,17 cases of adenomas(17/303,5.6％) were found,of which 4 (4/303,1.3％) were advanced ones.Colorectal cancers were found in 2 patients (0.7％,2/303),both in patients aged 36-50.The detection rate for colorectal neoplasms (including adenoma and cancer) in patients with chronic constipation aged 18-35 was significantly lower than that in patients aged 36-50[1.2％(3/260) VS 6.3％(19/303),P=0.002,95％CI:0.05-0.60].Conclusion The detection rate for colorectal neoplasms in patients aged 18-35 years with chronic constipation is relatively low,and colonoscopy is not recommended for them.

Method of detection of negative terminology in Chinese electronic medical record / 生物医学工程学杂志

The method for detecting the negative terms in Chinese electronic medical record (EMR) is useful in providing evidence for constructing concept index. In this respect, we adopted an improved method which combined maximum matching with mutual information in order to extract terms in EMRs. This method can overcome the influence of overlay ambiguity. In addition, for the determination of negative semantic, we also adopted an improved method which combined rule-based method with word co-occurrence. This new method can reduce the probability of appearance of false positive terms caused by punctuation input errors. The result showed that the negative predictive value is 7.85% higher than the rule-based method.
