一、工作任务的进展情况
1. After the opening report, Mr. Zhang gave us a meeting about the midterm preparations and briefly guided us on the next tasks; 2. Preparation of metallographic specimen
Coarse grinding: hand for soft materials can be filed flat, general materials are used in the grinder. Operation should utilize the side of the grinding wheel to ensure that the specimen grinding. Pay attention to the contact pressure should not be too large at the same time to constantly use water cooling to prevent the temperature rise caused by the internal organization changes. When chamfering at the end, prevent the sandpaper from being scratched during fine grinding. However, the specimens that need to observe the surface layers such as decarburization and carburization should not be chamfered, and sometimes electroplated covers are used to prevent chamfering of the edges of these specimens. Rough grinding is completed, where the surface layer of metallurgical inspection of the edges should be chamfered into a small arc, so as not to
In the subsequent process will be the sandpaper or polished material will be cracked. It may even be hooked by the polishing material and be thrown out, resulting in accidents.
Fine grinding: The purpose of manual fine grinding is to eliminate the deep and coarse abrasive marks left by rough grinding in preparation for polishing. Fine grinding itself consists of a number of operations, that is, in each number of sandpaper from coarse to fine sequence. The grinding tool for manual fine grinding is sandpaper. According to the size of the abrasive particles sandpaper is divided into various sizes, which are numbered separately. The manual grinding method is to put the use of flat glass plate or flat iron plate padded metallographic sandpaper on the push grinding. In order to ensure that the specimen test surface flat and does not produce arcs, the force applied on the grinding surface should strive to equalize the grinding surface and sandpaper in full contact. At the same time, grinding should be carried out in a single direction, when pushing forward to grind, and lift the specimen away from the sandpaper on the return trip. Fine grinding is generally in order from the 0 (w40) to start, one by one for a fine one of the sandpaper to push grinding, general steel specimens grinding to 04 sandpaper, soft materials such as aluminum, magnesium and other alloys can be ground to 05 sandpaper. Every time you change the next fine sandpaper, you should rinse the specimen and hands, and will be cleaned below the pad of glass plate, beware of coarse particles of sand into the fine sandpaper, while the direction of the grinding surface should be rotated 90 °, in order to observe the last grinding marks whether to grind off. In the fine grinding of softer metallographic specimens, such as aluminum, magnesium, copper and other non-ferrous metals should be coated with a layer of lubricant on the sandpaper, which can prevent the sand particles embedded in the soft metal materials, while reducing the phenomenon of surface tearing. Commonly used lubricants are motor oil, paraffin, gasoline solution, gasoline, saponified aqueous solution, glycerin aqueous solution. Preparation of specimens:

Specimen polishing manual polishing is to remove the grinding surface of the metallographic specimen grinding surface from the grinding of fine grinding left by the grinding marks, to become a flat and flawless mirror surface.
Although polishing is the last step in the preparation of a metallographic specimen and results in a smooth mirror surface, it is the experience of metallographers that more effort is required in the polishing of a metallographic specimen because the effect of polishing only removes a very thin layer of metal from the surface, and the result of the polishing process depends largely on the quality of the previous steps. Sometimes before polishing on the grinding surface left a small number of deep grinding marks, even if the increase in polishing time is difficult to remove, generally must be re-grinding. Therefore, the grinding surface should be carefully inspected before polishing, whether there is a single direction of uniform fine abrasive marks or should be resurfaced, so as not to waste time. This is an important part of improving the efficiency of metallographic specimen preparation.

Dissertation Interim Inspection Report Sample 4(1) Arrangement of research progress
Kawasaki disease is an acute, self-limiting systemic vasculitis that occurs in infants and young children under the age of 5. The disease was first discovered in Japan in 1962, first reported by the Japanese scholar Tomisaku Kawasaki in 1967, and has been reported in Europe, Asia, the United States, Australia, and South Africa since then. Since the etiology of this disease is unknown, the clinical manifestations are complex, and multiple systems of the body can be involved, especially the coronary arteries, in Japan and the United States has replaced rheumatic fever as the most common disease of acquired heart disease in children, and it has become one of the most common acquired heart diseases in children, and it may be one of the risk factors for ischemic heart disease in adults. In recent years, many advances have been made in the epidemiology, etiology and pathogenesis of KD, as well as in clinical management. This thesis has been analyzed and summarized according to the content and progress of the scheduled opening report, and has laid a theoretical foundation for the research of this paper by analyzing and summarizing the relevant literature review and the current status of domestic and international research.
(2) Currently completed research work and results
This paper has made a predetermined selection of relevant cases. In this paper, 20 cases of children with Kawasaki disease were selected from October 2013 to July 2014 who attended the Renhe Hospital of Three Gorges University, Yichang City Central Hospital and Yichang City No.2 Hospital, with age fluctuating from 6 months to 8 years old, mean age (2.10±1.83) years old, male:female=2:1.The subjects were numbered according to the order of enrollment, e.g., the first enrolled subject was numbered as 1. Diagnostic criteria were chosen from the diagnostic criteria set by the American College of Cardiology. The diagnostic criteria for Kawasaki disease were chosen from those established by the American Heart Association:
1) Fever lasting more than 5 days, not responding to antibiotic treatment, and not explained by other known illnesses;
2) Conjunctival congestion in both eyes (non-exudative);
3) Bright red, chapped lips and lips, with diffuse congestion of the puncta membranes of the lips and lips and a poplar tongue;
4) Erythema multiforme and dermal creeping;
5) In the acute phase there are hard swelling of the hands and feet, palmar erythema; in the recovery phase there is membranous desquamation of the skin migrating from the nail beds at the ends of the fingers (toes);
6) Acute non-suppurative cervical lymph nodes are large, often unilateral, and have a diameter of >1.5 cm or greater.
The diagnosis of Kawasaki disease is confirmed when at least 5 of the above criteria are met, with 1) being a requirement. The diagnosis was also confirmed if the child had unexplained fever for more than 5 days, with 3 of the other diagnostic criteria, and the presence of coronary artery dilatation or coronary artery aneurysm confirmed by two-dimensional echocardiography or coronary angiography, in addition to other diseases. The general data of all the patients were fully counted, and the patients were randomly grouped on this basis, from

and laying the foundation for the subsequent research.
(3) Research work to be accomplished in the later stage and schedule
In the later stage, this paper will firstly on the detection of specific cells expressing CCL5 and CCR5 in children with KD. 3-4 ml of peripheral blood was collected from children with KD and normal controls, PBMCs were isolated: 3-4 ml of sterile sodium heparin anticoagulated blood was separated and extracted from peripheral blood single nucleated cells (PBMCs) by Ficoll
density gradient centrifugation. Meanwhile, on the basis of analysis as well as detection
, the results were analyzed including:
1) to clarify the specific expression cells of CCL5 and CCR5 in peripheral blood PBMCs respectively;
2) for the T cells before and after the activation, what are the changes in the expression levels of CCL5 and CCR5;
3) to find out the relationship between CCL5 and CCR5 in the children with Kawasaki disease;
4) to find out the relationship between CCL5 and CCR5 in the children with Kawasaki disease. expression in children with Kawasaki disease.
After the above comparisons, the changes in the expression of CCL5 and CCR5 in the peripheral blood of children with Kawasaki disease were investigated, thus providing new ideas for the pathogenesis and treatment of Kawasaki disease. The results of the study are shown in the following table:

By examining the effects of chemokine CCL5/ CCR5 on T-cell chemotaxis, our experimental conclusions are as follows:
1. Chemokine receptors CCL5/ CCR5 were highly expressed in the peripheral blood of children with Kawasaki disease, suggesting that they may be closely related to the occurrence and development of Kawasaki disease in the peripheral blood of children with Kawasaki disease, in addition, the receptor CCRS may be one of the markers of Kawasaki disease.
2. The chemokine receptor CCL5 is clearly expressed in the peripheral cells of children with Kawasaki disease and is a functional receptor.

4. Binding of the chemokine CCLS to its receptor CCRS promoted motility, invasiveness, chemotaxis, and proliferative effects in peripheral cells of children with Kawasaki disease, the mechanism of which may be that the CCL5/ CCR5 bioaxis initiates calcium-ion-related signaling within the cancer cells by causing alterations in intracellular calcium ion concentrations.
(4) Difficulties and problems
Chemokines, a member of the cytokine superfamily, are a class of small-molecule proteins with a directed chemoattractive effect on cells, which can directionally attract immune cells to participate in the immune response and immunopathological processes [12]. To date, at least 50 chemokines have been identified, which are composed of 70-125 amino acids with molecular weights ranging from 8-11 KD. Most chemokines contain two characteristic disulfide bonds formed by four conserved cysteines, so they have a very similar high-level structure with an α-helix at the C-terminus and an irregular N-terminus, and have a relatively high biological activity to bind to receptors.
Chemokines were first discovered as chemotactic mediators, but with the in-depth study of chemokines, it is now recognized that chemokines not only have chemotactic effects on leukocytes, but also play a wide range of physiological and pathological roles in the development of immune cells and organs, the process of immune response, inflammatory responses, pathogen infections, trauma repair, as well as tumor formation and metastasis, etc. [14-16]. With the in-depth study of chemokines and their receptors in recent years, many scholars at home and abroad have found that the combination of the two in autoimmune diseases on the recruitment of T cells and chemotaxis, and will be the corresponding T cell aggregation to the target organ to occur tissue and organ damage.Wenzel et al. in the study of systemic lupus erythematosus (SLE), found that the combination of CXCL10 and its receptor CXCR3 can be directed to the recruitment of cytotoxic T cells into the target organ. cytotoxic T cells into the target organ ultimately causing skin damage; Barone et al. showed that the expression of CXCL9, CXCL10, CXCL11 and the receptor CXCR3 was elevated in the lacrimal corneal epithelial cells of patients with desiccation syndrome (SS); Goulvestre et al. concluded that CCL21, CXCL12, CXCL11, and CXCL3 were the most effective cytokines in the thyroid gland, and CCL21, CXCL12, CXCL12, CXCL11, CXCL11, and CXCL11 were the most important cytokines in the thyroid gland, Goulvestre et al. studied the cytokines and corresponding chemokines expressed in thyroid tissues, and concluded that CCL21, CXCL12, CXCL13, and CCL22 were increased in the thyroid tissues of patients with autoimmune thyroid disease (AITD), and the expression of CXCL12,
Interim report of master's thesis of the Three Gorges University
The expression of CXCL13, and CCL22 was increased in the thyroid tissues of patients with AITD. increased. The current research on chemokines and their receptors focuses on the role of chemokines in autoimmune diseases in recruiting and chemotaxis of T-cells to the target organs, but there are not many studies on their specific roles in Kawasaki disease, and the current research on the expression and significance of chemokine CCL5 and its receptor CCR5 in Kawasaki disease is relatively small, and there is a lack of support from the relevant literature and the guarantee of the data. At the same time, the content and extraction method of this paper are relatively complex. Therefore, it is necessary to spend more energy and time to ensure the reasonableness and accuracy of the research results, and also need to further collect and organize the literature, especially for the collection and investigation of foreign literature, so as to lay the foundation for the research of this paper.
(5) The possibility of completing all the thesis work as scheduled.
At present, some of the data of the research subjects have been collected, and the corresponding grouping and blood collection. Meanwhile, domestic scholars have already conducted research on the expression of CCL5 and CCR5 in other diseases, which can provide corresponding research methods and routes for reference. And the author's preliminary pre-test has isolated PBMC and successfully carried out the activation and proliferation of T cells. Therefore, I will be able to complete the thesis according to the initial progress, and ensure the quality of the research and the accuracy of the conclusions.
