Background: Endoscopic procedures are frequently performed to rule out any disease process which eventuates with either a positive or negative outcome. Association of patient demographics, clinical features with endoscopic outcomes are of paramount importance for better understanding and practice of endoscopy. Objectives: This study aimed to determine the frequency of positive endoscopic findings in patients with gastrointestinal symptoms compared to those with negative findings. As a secondary objective, the association between relevant demographics, symptoms, laboratory investigations and procedural outcomes of the participants and positive endoscopic findings were also assessed. Methods: A retrospective analysis of all the patients who underwent esophagogastroduodenoscopy from January 2017 to December 2017 was conducted. A total of 1066 endoscopy records were retrieved and using a convenience sampling technique, relevant data were manually entered to the questionnaires. Records with incomplete or inconsistent data were disregarded as per the exclusion criteria, resulting in 1011 patient records ultimately utilized for the study. All data were entered and analyzed using IBM SPSS 23.0. Results: The study comprised a total of 1011 patients where 52.2% were females and 47.8% males while the mean age of patients was 42.16 ± 15.45. Positive endoscopic findings were observed in 88.1%, where the most common finding was gastritis (49.1%). Approximately 14.5% had positive investigation findings for HBsAg and 23.1% were seropositive for anti-HCV antibody. P-values statistically significant were for age (p = 0.044), hematemesis (p = 0.002), betel quid addiction (p = 0.044), anti-HCV antibody (p = 0.043), HCV-RNA (p = 0.041) and “H. pylori” antigen (p = 0.032). Conclusion: Both genders were almost equally included where most patients presented between the 3rd and 5th decades of life. A high incidence of gastritis was noted. Positive endoscopic findings were associated with be

为了促进燃料电池的广泛应用,必须研发一种高效、经济的氧还原(ORR)催化剂材料替代目前使用的昂贵的Pt基催化剂.本文合成了NiO@rGO、Pd-NiO@rGO和Ag-NiO@rGO三种催化剂材料,并对其ORR催化性能进行了比较研究.结果表明,三种材料均具有催化ORR的能力,但与NiO@rGO相比,Pd-NiO@rGO和Ag-NiO@rGO展示了更加优异的性能,主要表现在其4电子转移ORR过程、起始电位增加,中间产物的产率降低和稳定性提高.其中,Pd-NiO@rGO作为ORR催化剂的性能最好.

We evaluated the clinical feasibility of using drugcoated balloon(DCB) angioplasty in patients undergoingprimary percutaneous coronary intervention(PPCI). Between January 2010 to September 2014,89 STelevation myocardial infarction patients(83% male,mean age 59 ± 14 years) with a total of 89 coronary lesions were treated with DCB during PPCI. Clinical outcomes are reported at 30 d follow-up. Left anterior descending artery was the most common target vessel for PCI(37%). Twenty-eight percent of the patients had underlying diabetes mellitus. Mean left ventricular ejection fraction was 44% ± 11%. DCB-only PCI was the predominant approach(96%) with the remaining 4% of patients receiving bail-out stenting. Thrombolysis in Myocardial Infarction(TIMI) 3 flow was successfully restored in 98% of patients. An average of 1.2 ± 0.5 DCB were used per patient,with mean DCB diameter of 2.6 ± 0.5 mm and average length of 23.2 ± 10.2 mm. At 30-d follow-up,there were 4 deaths(4.5%). No patients experienced abrupt closure of the infarctrelated artery and there was no reported target-lesion failure. Our preliminary experience showed that DCB angioplasty in PPCI was feasible and associated with a high rate of TIMI 3 flow and low 30-d ischaemic event.
