Under the goal of carbon peak, carbon neutrality, the oil and gas production industry needs to strengthen negative carbon, zero carbon and low-carbon technological innovation to promote industrial transformation and upgrading under the premise of continuously increasing and stabilizing production and ensuring energy security. The research and development of new technologies, new processes and new materials have given new eonnotation to green and carbon enhanced oil recovery technology. Theoretical research and field practice show that CO2 flooding, CO2 fracturing, air (deoxygenated air or N2) flooding, biomass-based flooding, microbial based flooding technologies have obvious carbon emission reduction effects, providing a new path for low-carbon neutrality in enhanced oil recovery field. In the future, we will continue to optimize the green enhanced oil recovery technology path, build a new generation of green and low-carbon enhanced oil recovery engineering technology system, carry out research on the carbon emission reduction potential of the whole process and the whole life cycle, and explore quantitative characterization method of green and low-carbon enhanced oil recovery technology.

OBJECTIVE: To investigate the clinical characteristics of anticoagulant-related nephropathy (ARN) induced by direct oral anticoagulants, so as to provide reference for clinical safe drug use. METHODS: Relevant literature databases at home and abroad (up to Sept. 30th, 2023) were retrieved, case report literature related to ARN induced by direct oral anticoagulants were collected. Patients’ gender, age, medication, comorbidities, occurrence of renal injury were recorded and statistically analyzed. RESULTS: A total of 36 patients were enrolled (3 domestic cases and 33 foreign cases), including 26 cases of dabigatran etexilate, 7 cases of rivaroxaban, and 3 cases of apixaban. There were 23 males and 13 females, the age ranged from 59 to 89 years, with an average age of 75. 75 years. Totally 22 cases had normal renal function and 14 cases had a history of chronic renal disease. Thirty-six patients had comorbidities/ past medical history; 22 cases had drug combination and 14 cases were not mentioned. The time from the use of anticoagulants to occurrence of renal injury was 2 d to 3 years, of which 30 cases had renal injury within 1 year. Renal biopsy was performed in 24 patients. Serum creatinine levels increased in 36 patients, mainly manifested as hematuria (16 cases of gross hematuria, 7 cases of microscopic hematuria), and a few patients showed oliguria (7 cases), anuria (1 case) or proteinuria (10 cases). After the diagnosis of renal injury, 36 patients stopped using direct oral anticoagulants and received different treatments. Among them, 6 patients received idarucizumab ( dabigatran etexilate reversal agent ), 14 patients underwent hemodialysis, 15 patients received glucocorticoid treatment, and 6 patients received intravenous fluid. After drug withdrawal and symptomatic treatment, the renal function of 24 patients was improved or returned to normal, but there were still 6 patients showed no improvement, 3 patients deteriorated, and 3 patients died ( died from other complications). CONCLUSIONS: Clinically, it is necessary to be alert to the occurrence of ARN induced by direct oral anticoagulants, pay close attention to patients’ renal function and clinical manifestations such as hematuria during medication, identify and diagnose as soon as possible, and perform renal biopsy if necessary. Once ARN occurs, symptomatic supportive treatment should be given according to the patients’ condition. [ABSTRACT FROM AUTHOR]

Taking the characteristic Fu Brick tea and goat milk of Shaanxi Province as raw materials, and taking the antioxidant stability, physical stability and digestive stability as the main indicators, the stability of the complex milk system of Fu Brick tea and goat milk was studied. The results showed that the antioxidant activity of the complex system of Fu Brick tea and goat milk decreased after being placed at 25 ℃ for 7 days. Among them, the antioxidant activity of the compound milk system containing activated eurotium cristatum was the best（sample 1), the second was the compound milk system containing inactive eurotium cristatum（sample 2), the last one is the compound milk system without eurotium cristatum（sample 3). The results of the physical stability test showed that the physical stability of Fu Brick tea and goat milk complex milk system decreased with the extension of time, the physical stability of sample 3 is stronger than that of sample 1 and sample 2, scanning electron microscope microscopic characterization showed that eurotium cristatum in tea soup could form a complex with casein from sheep milk, which reduced the physical stability of the complex system. Digestive stability test results show that the longer duration of digestion, casein in vitro digestibility are growing, but compared with the control group, Fu Brick tea with goat milk composite emulsion system inhibits milk protein digestion, and stomach digestion phase inhibition effect is stronger than the intestinal digestion phase, the strongest inhibitory effect of sample 2, second sample1, sample 3 is the worst. The research results provide important theoretical basis and technical support for further development of new products of Fu Brick tea and goat milk tea. [ABSTRACT FROM AUTHOR]

The concept and connotation of microbial/chemical/gas flooding synergistic EOR technology are expounded from three aspects: material synergy, mechanism synergy and space-time synergy.The mechanism, characteristics and development status of microbial/chemical flooding synergistic oil displacement technology (microbial activated water flooding, microbial/chemical profile control, microbial/chemical flooding combined oil displacement） and microbial/gas flooding synergistic oil displacement technology (air assisted microbial oil displacement, microbial/CO2 synergistic oil displacement） are summarized, in the future, we will continue to explore the micro synergy mechanism, green and low-carbon technology, and expand the scope of application of the reservoir.

Volume holographic storage has be paid much attention as the increasing requirement of data storage. To overcome the disadvantage of storage medium properties and low popularity of holographic storage, the demonstration instrument of volume holographic storage with polymeric holographic disc is investigated. The preparation of polymeric disc is thermal initiation of radical polymerization. In the materials, poly methyl methacrylate is matrix, and phenanthrenequinone is photosensitizer. The holographic disc with high thickness and transparency has the ability of write once and read permanent, and its thermal and optical stability is excellent. The disc is suitable to enhance the storage capacity and reduce the cost of device because its sensitive wavelength covers the wavelength of DPSS laser.There are high diffraction efficiency and image quality by measuring the device properties. The multiplexing method will be able to achieve high storage density on one spot. The new demonstration instrument can demonstrate all of the process including data collection, process, storage and read. The preparation of medium, molding technics, and photochemical mechanism of the photopolymer can present to the student for understanding next information storage technology. [ABSTRACT FROM AUTHOR]
