AIM:To investigate the efficacy and adverse effects of antioxidant therapy in acute pancreatitis(AP),chronic pancreatitis(CP) and post-endoscopic retrograde cholangiopancreatography pancreatitis(PEP).METHODS:Pub Med,Scopus,Google Scholar,Cochrane library database,and Evidence-based medicine/clinical trials published before August 2014 were searched. Clinical and laboratory outcomes of randomized trials of antioxidant therapy in patients with AP,CP and PEP were included. The methodological quality of the trials was assessed by the Jadad score based on the description of randomization,blinding,and dropouts(withdrawals). The results of the studies were pooled and meta-analyzed to provide estimates of the efficacy of antioxidant ***:Thirty four trials out of 1069 potentially relevant studies with data for 4898 patients wereeligible for inclusion. Antioxidant therapy significantly reduced the length of hospital stay in AP patients {mean difference-2.59 d(95%CI:-4.25-(-0.93)],P = 0.002}. Although,antioxidant therapy had no significant effect on serum C reactive protein(CRP) after 5-7 d in AP patients [mean difference-9.57(95%CI:-40.61-21.48,P = 0.55],it significantly reduced serum CRP after 10 d {mean difference-45.16 [95%CI:-89.99-(-0.33)],P = 0.048}. In addition,antioxidant therapy had no significant effect on CP-induced pain [mean difference-2.13(95%CI:-5.87-1.6),P = 0.26]. Antioxidant therapy had no significant effects on the incidence of all types of PEP [mean difference 1.05(95%CI:0.74-1.5),P = 0.78],severe PEP [mean difference 0.92(95%CI:0.43-1.97),P = 0.83],moderate PEP [mean difference 0.82(95%CI:0.54-1.23),P = 0.33],and mild PEP [mean difference 1.33(95%CI:0.99-1.78),P = 0.06]. Furthermore,while antioxidant therapy had no significant effect on serum amylase after less than 8 h sampling [mean difference-20.61(95%CI:-143.61-102.39),P = 0.74],it significantly reduced serum amylase close to 24-h sampling {mean difference-16.13 [95%CI:-22.98-(-9.28)],P <

Colorectal cancer usually present with known symptoms while there are less common manifestation including abscess formation which can be intra or extra peritoneal. A 60-year-old Caucasian male with a history of RLQ abdominal pain, nausea, vomiting and anorexia from 15 days ago referred to surgery ward. Ultrasound showed a hypoachoic lesion with diameters 50 mm x 70 mm in RLQ of abdomen and a round echogenic area in right lobe of liver with diameter 15 mm. The findings were revealed an abscess located in right lilac fossa then local drainage of abscess was performed. Four days later the patient was re-admitted because of severe abdominal distention and lack of bowel movement. Laparoscopy was performed before proceeding with further examinations, due to the poor general condition of the patient. The sigmoid was adherent into the abdominal wall and mild intestinal loop distention and apple-core view was observed during operation. Can- cer of sigmoid complicated by a right lilac fossa abscess was diagnosed and Hartman colestomy was undertaken. At the last follow-up examination 3 months after operation, the patient was in good health with no clinical evidence of recurrence.

Purpose: The use of port catheters is well accepted in the management of patients with malignancy. In this study, we compare the technical success and the complication rates of ultrasound guided Port-A-Cath implantation with doing this procedure by using the anatomical landmark method. Methods: In a retrospective study, from 2006 to 2009, medical files of 104 patients who had undergone Port-A-Cath implantation were reviewed. The indication for port catheter implantation was malignancy in all cases. Among our patients, Port-A-Cath implantation was done in 63 patients by using landmark method and in 41 patients by guidance of ultrasound. All patients had been observed for complications including pain, port infection, and port thrombus, thrombus of central veins, skin necrosis, and success in using of Port-A-Cath for at least one month following the procedure, in the vascular clinic. Results: in landmark method group, 2 catheters were non-functional just after placement (3.2%) while all Port-A-Caths in ultrasound-guided group were functional. Ten patients (15.9%) in land mark group and 1 patient (2.4%) in ultrasound-guided group were complicated. The difference between complication rate in anatomic landmarks method and ultrasound-guided method was statistically significant (p There was no significant difference in two groups in duration of port placement (p < 0.345), age (p < 0.444), site of port placement (p < 0.244) or type of malignancy (p < 0.18). Conclusion: Considering high rate of success and low complications in placement of Port-A-Cath with ultrasound guidance, this method is superior to the land mark method in patients with malignancy.

Review on application of nanoparticles for EOR purposes: A critical review of the opportunities and challenges

引用

Chinese Journal of Chemical Engineering 2019年第2期27卷 237-246页

作者： Yousef Kazemzadeh Sanaz Shojaei Masoud Riazi mohammad Sharifi Department of Petroleum Engineering Amirkabir University of Technology Tehran Polytechnic Enhanced Oil Recovery (EOR) Research Centre IOR/EOR Research Institute Shiraz University Petroleum Engineering Department School of Chemical and Petroleum Eng. Shiraz University

Nanoparticles have already gained attentions for their countless potential applications in enhanced oil ***-sized particles would help to recover trapped oil by several mechanisms including interfacial tension reduction, impulsive emulsion formation and wettability alteration of porous media. The presence of dispersed nanoparticles in injected fluids would enhance the recovery process through their movement towards oil–water interface. This would cause the interfacial tension to be reduced. In this research, the effects of different types of nanoparticles and different nanoparticle concentrations on EOR processes were investigated. Different flooding experiments were investigated to reveal enhancing oil recovery mechanisms. The results showed that nanoparticles have the ability to reduce the IFT as well as contact angle, making the solid surface to more water wet. As nanoparticle concentration increases more trapped oil was produced mainly due to wettability alteration to water wet and IFT reduction. However, pore blockage was also observed due to adsorption of nanoparticles, a phenomenon which caused the injection pressure to increase. Nonetheless, such higher injection pressure could displace some trapped oil in the small pore channels out of the model. The investigated results gave a clear indication that the EOR potential of nanoparticle fluid is significant.

作者： Mehrdad Mahdian Mojtaba Sehat mohammad Reza Fazel hossein Akbari Habibollah Rahimi Mahdi mohammadzadeh Trauma Research Center. Kashan University of Medical Sciences Kashan Iran Department of Biostatistics and Epidemiology School of Health Kashan University of Medical Sciences Kashan Iran

Purpose： The aim of this study was to analyze the trend of road traffic fatalities in Kashan Region, lran, in a period of eight years. Methods： Through a cross-sectional study, all road traffic deaths classified under the VO1-V99 codes according to ICD-10 in Kashan region, central Iran, from March 2006 to March 2013 and population data were collected from the registration system of Kashan University of Medical Sciences. Years of lost life （YLL） and mortality rates were calculated regarding age, gender and year of the accident. Generalized linear model （GLM） with Poisson log-linear link was used to evaluate the effects of the mentioned variables on mortality rate. Results： During the period of the study （8 years）, 928 people （767 men） died due to road traffic injuries （RTIs）. The total YLL was 20,818. The mortality rate due to RTIs has been declined constantly from 43.1 in March 2006 to 21.1 per 100,000 in March 2013. The highest mortality rate was found in the age group of over 60 years old and the lowest in the age group of 0-14 years old. Both mortality rate and YLL was greater in men than in women. Poisson regression showed that age, gender and year of the accidents had a significant effect on mortality rate （p 〈 0.001 ）. Conclusion： Although there has been a constant decline of mortality rate in Kashan area within the study period, the value remains higher than the mean level of Eastern Mediterranean region and the global average, which is a notable fact for policymakers and authorities.
