| 1 | Ultrasound guided percutaneous cholecystostomy in high-risk patients for surgical intervention显示文摘AIM: To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia. METHODS: The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases. RESULTS: Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 × 103 ± 1.3 × 103 μg/L vs 13 × 103 ± 1 × 103 μg/L, P < 0.05 for 24 h after PC; 13.7 × 103 ± 1.3 × 103 μg/L vs 8.3 × 103 ± 1.2 × 103 μg/L, P < 0.0001 for 72 h after PC), C -reactive protein (51.2 ± 18.5 mg/L vs 27.3 ± 10.4 mg/L, P < 0.05 for 24 h after PC; 51.2 ± 18.5 mg/L vs 5.4 ± 1.5 mg/L, P < 0.0001 for 72 h after PC), and fever (38 ± 0.35℃ vs 37.3 ± 0.32℃, P < 0.05 for 24 h after PC; 38 ± 0.35℃ vs 36.9 ± 0.15℃, P < 0.0001 for 72 h after PC). Sphincterotomy and stone extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recoveredwith medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter. CONCLUSION: As an alternative to surgery, percutan- eous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low mortality and morbidity. Delayed cholecystectomy and ERCP, if needed, can be performed after the acute period has been resolved by percutaneous cholecystostomy. | Huseyin Bakkaloglu Hakan Yanar Recep Guloglu Korhan Taviloglu Fatih Tunca Murat Aksoy Cemalettin Ertekin Arzu Poyanli | 2006 | World Journal of Gastroenterology2006，12，44： | 15 |
| 2 | Planned second-look laparoscopy in the management of acute mesenteric ischemia显示文摘AIM: To investigate the role of second-look laparoscopy in patients with acute mesenteric ischemia (AMI).METHODS: Between January 2000 and November 2005, 71 patients were operated for the treatment of AMI. The indications for a second-look were low flow state, bowel resection and anastomosis or mesenteric thromboembolectomy performed during the first operation. Regardless of the clinical course of patients, the second-look laparoscopic examination was performed 72 h post-operatively at the bed side in the ICU or operating room.RESULTS: The average time of admission to the hospital after the initiation of symptoms was 3 d (range, 5 h-9 d). In 14 patients, laparotomy was performed. In 11 patients, small and/or large bowel necrosis was detected and initial resection and anastomosis were conducted. A low flow state was observed in two patients and superior mesenteric artery thromboembolectomy with small bowel resection was performed in one patient. In 13 patients, a second-look laparoscopic examination revealed normal bowel viability, but in one patient, intestinal necrosis was detected. In two of the patients, a third operation was necessary to correct anastomotic leakage. The overall complication rate was 42.8%, and in-hospital mortality rate was 57.1% (n = 6).CONCLUSION: Second-look laparoscopy is a minimally invasive, technically simple procedure that is performed for diagnostic as well as therapeutic purposes. The simplicity and ease of this method may encourage wider application to benefit more patients. However, the timing of a second-look procedure is unclear particularly in a patient with anastomosis. | Hakan Yanar Korhan Taviloglu Cemalettin Ertekin Beyza Ozcinar Fatih Yanar Recep Guloglu Mehmet Kurtoglu | 2007 | World Journal of Gastroenterology2007，13，24： | 11 |
| 3 | Salinization Increase due to Climate Change Will Have Substantial Negative Effects on Inland Waters: A Call for Multifaceted Research at the Local and Global Scale显示文摘Globally,temperature and precipitation patterns are predicted to change markedly as a result of climate change.Particularly,the regions with a cold or hot semi-arid climate and the Mediterranean climate zone are expected to be strongly affected.1,2 A 25%–30%decrease in precipitation and increased evaporation are expected by the end of the 21st century in the Mediterranean region,to be accompanied by an even stronger reduction in runoff of up to 30%–40%,1,2 and this will lead to increasing salinization of lakes in these areas. | Erik Jeppesen Meryem Beklioglu Korhan Ozkan Zuhal Akyurek | 2020 | The Innovation2020，1，2： | 6 |
| 4 | Feature Selection for Malware Detection on the Android Platform Based on Differences of IDF Values显示文摘Android is the mobile operating system most frequently targeted by malware in the smartphone ecosystem,with a market share significantly higher than its competitors and a much larger total number of applications.Detection of malware before being published on official or unofficial application markets is critically important due to the typical end users'widespread security inadequacy.In this paper,a novel feature selection method is proposed along with an Android malware detection approach.The feature selection method proposed in this study makes use of permissions,API calls,and strings as features,which are statically extractable from the Android executables(APK files)and it can be used in a machine learning process with different algorithms to detect malware on the Android platform.A novel document frequency-based approach,namely Delta IDF,was designed and implemented for feature selection.Delta IDF was tested upon three universal benchmark datasets that contain Android malware samples and highly promising results were obtained by using several binary classification algorithms. | Gokcer Peynirci Mete Eminagaoglu Korhan Karabulut | 2020 | Journal of Computer Science & Technology2020，35，4： | 4 |
