Authors: Lin Wendong
Published: December 2023

Chronic renal failure (CRF) is a clinical syndrome characterized by chronic progressive renal parenchymal damage caused by various reasons, resulting in obvious atrophy of the kidney and inability to maintain basic functions. Metabolite retention, imbalance of water, electrolyte and acid-base balance, and systemic involvement of various systems are the main manifestations in clinic. Due to its complicated metabolic disorder, once it develops to the stage of renal failure or even the end stage of uremia, it is often more difficult to treat other renal diseases. Therefore, early detection, early diagnosis and early treatment of chronic renal failure are of great significance to improve the therapeutic effect of patients. In this project, 150 subjects were divided into chronic renal failure group (75 cases) and healthy group (75 cases). By analyzing the data of renal function indexes (blood creatinine, urea nitrogen, uric acid) of patients with chronic renal failure and healthy control group, the clinical significance of blood creatinine, urea nitrogen and uric acid level detection for chronic renal failure was discussed, and the importance of blood creatinine, urea nitrogen and uric acid monitoring for chronic renal failure was explained, providing scientific basis for timely prevention or delay of chronic renal failure. Biochemical tests were carried out on 150 serum samples from the combined healthy group of chronic renal failure. the values of uric acid, urea nitrogen and serum creatinine detected by the two groups were counted and treated with statistical methods. the results showed that the values of urea nitrogen, uric acid and serum creatinine in the chronic renal failure group were significantly higher than those in the healthy group, and the same indexes in the two groups were compared, P<0.05. statistics showed that the difference of the same data between the two groups was significant. Serum uric acid, urea nitrogen and creatinine are easy to detect and the test results are relatively accurate. The results can be used for auxiliary diagnosis of patients with chronic renal failure and have clinical significance for diagnosis of patients with chronic renal failure.

Published: December 2023

"ATP-induced cell death" is a novel form of cellular demise identified since 1991, typically characterized by a substantial accumulation of adenosine triphosphate (ATP) and the activation of ATP membrane receptors during the cell death process. The perturbation of ATP homeostasis is intricately linked to mitochondrial function. In recent years, ATP-induced cell death (AICD) has emerged as a discernible pattern of cell demise attributed to heightened levels of extracellular ATP (eATP). This phenomenon is intimately associated with the pathophysiological mechanisms underpinning a plethora of maladies, including malignancies, neurodegenerative disorders, ischemia-reperfusion injury, renal impairment, and hematological conditions. The strategic modulation of ATP-induced cell death to mitigate the onset and progression of these related diseases has garnered significant attention and stands as a focal point in etiological research and therapeutic interventions. Nevertheless, the functional alterations and precise molecular mechanisms governing ATP-induced cell death demand further comprehensive exploration. This paper comprehensively synthesizes the most recent advancements in the understanding of ATP-induced cell death mechanisms, with the overarching objective of serving as a reference for a deeper comprehension of its pathogenesis and the proposition of novel therapeutic targets for the management of associated diseases.
Using dsRNA Targeting unc-22 to Demonstrate Gene Knockdown Phenotypes in C.elegans in the Undergraduate Biology Lab Setting
Authors: Wang Ruoyi
Published: December 2023

The discovery of RNA interference (RNAi) and its role in gene silencing has revolutionized the study of genetics. In this study, we utilized Caenorhabditis elegans (C. elegans) to demonstrate the effects of RNAi in an undergraduate laboratory setting. Specifically, we targeted the unc-22 gene, responsible for coding the 'twitchin' protein which affects muscle coordination in C. elegans. By employing the L4440 vector, we inserted the unc22 gene into E.coli cells and then induced the production of double-stranded RNA (dsRNA) targeting unc-22 using IPTG. Feeding the C. elegans with these dsRNA-expressed E.coli resulted in a 'twitcher' phenotype, indicative of the unc-22 gene knockdown. This streamlined project offered students not only hands-on molecular experimentation but also experience in data analysis of worm movement. Moreover, through gel electrophoresis and bacterial transformation, students observed the nuances of RNAi machinery in action. The study reaffirms the importance of using C. elegans as a model organism for genetics and evolution studies and offers an experiential learning platform for students to understand the fundamental mechanisms of gene silencing.

Authors: Jin Long , Su Rong , Gao Feng
Published: December 2023

Severe CO2 corrosion and O2 corrosion occurred during the extraction of a certain gas well. Six commonly used corrosion inhibitors for a certain gas well were evaluated through indoor weight loss tests. It was found that the corrosion inhibition effect of No. 1 corrosion inhibitor in CO2 and O2 environments was the best compared to the other five corrosion inhibitors. The corrosion inhibition efficiency can be divided into 96% and 93%, and the dosage is small, which meets the requirements of the target gas well corrosion inhibitor. The corrosion inhibition mechanisms of the six corrosion inhibitors all conform to the adsorption mechanism, and their action mechanisms are all "negative catalytic" effects. Through adsorption, the activation energy of the cathodic and anodic reactions is increased, which hinders the occurrence of corrosion reactions. Among them, corrosion inhibitors 1, 2, 3, and 5 are mixed corrosion inhibitors that mainly inhibit anodic reactions, while corrosion inhibitors 4 and 6 are mixed corrosion inhibitors that mainly inhibit cathodic reactions.

This study integrates the downscaling model of electricity production consumption, the balance equation of electricity inflow and outflow, and the actual connectivity between provincial power grids into a research framework, and develops a downscaling method for inter-regional power transmission data, thereby obtaining a complete inter provincial power transmission dataset. It was found that from 2005 to 2020, the source of power supply gradually shifted from the Central China Power Grid to the Southwest Power Grid. Sichuan, Yunnan, and some provinces in the southwest region have become important sources of electricity supply. The scale of power transfer from the source point and the scale of power transfer from the sink point are both showing an increasing trend, and the scale of inter provincial and inter regional power transmission is constantly expanding, resulting in a strengthening trend of the close density of network connections.

The loading-unloading physical and mechanical characteristics of fractured coal-bearing strata are greatly affected by fracture occurrence. In order to study the physical and mechanical response characteristics of fractured rock under cyclic compression, this paper takes prefabricated fractured sandstone samples with different dip angles as the object, and uses uniaxial cyclic loading and unloading test to study the influence of crack dip angle on sample strength, failure mode and crack propagation law. The results show that with the increase of crack inclination angle, the cyclic loading and unloading peak strength and elastic modulus of the sample increase significantly, and the peak strain decreases first and then increases. During the cyclic loading process, the area of the hysteresis loop gradually decreases, the slope gradually increases, the energy con-sumed by the hysteresis loop gradually decreases, the cumulative plastic deformation increases, and the curve shape presents a “concave” type; when it is 15 ° and 30 °, the cracks at the crack tip are wing cracks. When it is 45 °, the cracks at the crack tip are secondary inclined cracks and wing cracks. When it is 60 °, 75 ° and 90 °, the cracks at the crack tip are secondary coplanar cracks and wing cracks. With the increase of fracture dip angle, the number of cycles and peak strength at failure are increasing.

At lane 20207 and lane 50207 of the 80207 working face of Sitai Mine, many small faults are exposed, and their extension is unknown, which causes great interference to safe and efficient mining and even normal production of the working face. In order to guide the rational transformation and safe and efficient production of the working face with science, Sitai Coal Mine commissioned Henan Polytechnic University to find out the extension of the exposed fault on the face and other geological anomalies by using geophysical exploration methods. According to the purpose of geophysical exploration in Sitai coal mine, combined with the geological conditions of the working face, the SUMMIT II EX type seismic channel wave exploration produced by DMT company of Germany is selected to explore the 80207 working face with the combined detection method of transmission and reflection. According to the detection results, combined with the existing hydrogeological data of Sitai mine, the relative channel wave anomaly area is delineated. The results show that the seismic channel wave exploration can provide a basis for the prevention and control of mine water disaster conveniently and effectively.

In recent years, photocatalytic technology has become a research hotspot for the treatment of organic wastewater, uranium containing wastewater, and Cr (VI) containing wastewater due to its advantages of environmental friendliness, simple reaction process, and high degradation efficiency. Uranium, as the main component of nuclear fuel, is an important strategic resource. The separation and enrichment technology of uranium is of great significance for the sustainable development of nuclear energy. Previously, a series of solid adsorption materials for uranium extraction have been developed, such as inorganic minerals, mesoporous silica, magnetic nanomaterials, carbon based materials, and advanced porous materials. However, due to the comprehensive performance of stability, removal kinetics, adsorption capacity, selectivity, and reusability, the practical application of these materials is still inevitably limited. And photocatalytic technology can reduce easily soluble and easily flowing U (VI) to more difficult to dissolve and relatively non flowing U (IV), thus overcoming the above problems and achieving the reduction and fixation of uranium. Moreover, this technology only relies on inexhaustible solar energy as energy source, and has the advantage of green and clean. Therefore, the use of photocatalytic technology to separate and enrich uranium is of great significance for the sustainable development of nuclear energy. However, most semiconductor photocatalysts have shortcomings in terms of light absorption capacity and charge separation ability, which limits their practical application in wastewater treatment. In addition, there are many difficulties in photocatalytic treatment of wastewater, such as the fast recombination speed of photo generated electron hole pairs generated by the catalyst, the weak visible light response of most single semiconductor materials, the need to introduce additional sacrificial agents to capture holes in the reaction, and the introduction of inert gases to eliminate the interference of oxygen. This article provides a certain scientific basis for expanding the application of various photocatalytic technologies in wastewater treatment.
