Medical opening report sample (Selected 5)
University life and is about to come to an end, we have received the task to do the graduation design, before doing the graduation design instructor will ask to write the opening report first, then the excellent opening report is what kind of? The following is my collection of medical opening report sample for you, just for reference, we take a look at it.
Medical opening report Part 1
(a) the background of the topic
With the rapid changes in science and technology and the rapid improvement of living standards, people's requirements for physical health protection are increasingly high. When the patient highlights heart disease, cerebral hemorrhage, hypoglycemia, epilepsy and other sudden illnesses, the patient's life will largely determine whether the patient can be effectively rescued in the shortest possible time. This naturally promotes the development of first aid business and popularization of common first aid knowledge. However, in China, the whole first-aid system is still in its infancy, and there are many hidden dangers that may affect the efficiency of first-aid after a patient suffers from a sudden illness. For example, if a heart patient suddenly falls down while walking along the roadside, what should he or she do? Make a phone call? What if there is no public **** phone nearby? Get help? Once handled incorrectly by non-professionals, resulting in delayed treatment is likely to be botched. Take a taxi to the hospital? Data show that brain cells begin to die 5-10min after the patient's heart stops beating. In other words: in this case, it is necessary to have emergency medical professionals arrive as soon as possible to ensure the patient's safety. Thinking from this perspective, I came up with this idea: can we design a device to make the process of a patient's fall due to a sudden attack to the doctor's arrival as soon as possible to simplify the process?
After reviewing the information at the patent office, I realized that there is no such product design in China. A similarly creative design is: two metal contacts are set inside a bottle, and the inside of the bottle is filled with some mercury. When a person stands, the mercury is concentrated in a contact, the circuit is broken. When the person falls to the ground, the bottle tilts so that the mercury touches both contacts, the circuit is triggered, and the siren built into the bottle sounds an alarm, signaling for help. This design is obviously very crude.
(1) It only determines whether to alarm or not by the angle of the body tilt, not according to the real physiological condition, which is bound to have a high false alarm rate.
(2) It does nothing more than get someone's attention in the shortest possible time without simplifying the whole process, so it won't have a substantial impact on improving the efficiency of ambulance service.
Combining my own vision and the shortcomings of existing facilities, I hope to make a "post-fall first aid system": when the patient falls to the ground, a monitoring device to sense the patient's physiological status, such as blood pressure, pulse, and other numerical analysis. Once the patient is determined to have developed a disease, a radio signal is sent to the nearest first aid station, which locates the patient's position via gps and dispatches first aiders as quickly as possible.
However, after more than two months of exploration, there was almost no progress, and I almost came to the point of giving up. However, in the teacher's continuous encouragement and inspiration, one day, inspiration fortunately patronized my brain - sound and light help, wired, wireless phone alarm are mature technology, the key lies in the absence of an intelligent switching device that can determine the patient falls due to other reasons with a sudden onset of falls.
Once this design can be realized, it will have significant practical and social value. First of all, it makes the patient in the first aid the most critical link to get the greatest protection, greatly reducing the risk of sudden illness; Secondly, it will make the first aid industry appear new concepts, new operation mode, but also will promote the popularization and promotion of related products (such as gps); In addition, it can make a lot of sudden illnesses of middle-aged and old people to face the life with a relaxed, optimistic mood, participate in more In addition, it will enable many middle-aged and elderly people suffering from sudden illnesses to face life with a relaxed and optimistic mood and participate in more social activities.
(2) Research Program
1. Looking at the whole design idea, it can be roughly divided into three major parts
The first stage: go to the hospital to collect further information about the specific physiological reactions of the patients (especially the elderly) during the onset of the fall, such as the posture of the fall, the changes in blood pressure and pulse, etc. The key task of this stage is to collect information from the patients through the hospitals, so that the patients can have a better understanding of their physiological reactions to the fall. The key task in this stage is to analyze the data to capture the difference between a fall in ordinary conditions and a fall due to illness. And the data estimation will focus on the collection of ECG and blood pressure values.
Phase 2: Selection of the appropriate way to receive the required physiological signals. The key to this phase is the selection of appropriate sensors to receive the relatively weak physiological signals. It is estimated that the issues to be considered in this phase are what performance sensors to choose and how to distribute the sensors to optimize the experiment.
Phase 3: Design and analyze the circuit. The task of this stage is to analyze the electrical signals received by the sensor through the logic circuit to determine whether the user's physical condition is normal. The main difficulty lies in how to find an appropriate mathematical model to match the experimental data and how to implement the model through the circuit. Currently, there are two main implementation schemes: one is signal arithmetic and recognition through logic circuits; the other is recognition using microcontroller programming. The first option has the advantage of dealing with the problem directly, but when the signals to be processed are quite complex, relying on microcontroller programming becomes more appropriate. Which program to choose also depends on the specific circumstances.
Phase 4: Integrate the results of the above phases to complete the finished product.
The whole project will be completed mainly under the guidance of Mr. Zhou Qinglin and Mr. Zhou Wei. The general schedule is as follows: January 15, 20XX - June 1, 20XX model completion June 1, 20XX - August the whole system testing, perfect
2. Expected research results
(1) to get a specific mathematical model is used to determine the user's physical condition according to the blood pressure, pulse and other physiological parameters.
(2) To obtain a specific mathematical model to determine the user's physical condition based on physiological parameters such as blood pressure and pulse.
(2) To complete the specific design of the patient condition monitoring/alarm system and the other two parts (gps and first aid station schematic design) of the "first aid system after collapse", and to realize the coordination of the three systems in the demonstration.
It is expected that the main difficulty will be the blindness and lack of clarity at the beginning of the work due to the lack of experience. In addition, since the whole design involves many highly specialized aspects, I must have a lot of patience and determination to step by step to build up the required knowledge solidly.
(3) Feasibility of the study
(1) The preparation of knowledge and ability required for the study of this topic should be achievable through my efforts.
(2) The pathway to the mentor and relevant expert counseling needed for the study of this topic is already available.
(3) The material and environmental conditions needed for the research of this topic are not high and are relatively easy to solve.
Medical Thesis Report Part 2
Over the past few decades, China's clinical medicine has made steady and rapid development, along with the development of evidence-based medicine has also played a wide range of applications in clinical medicine. The clinical laboratory discipline has developed from "medical testing" to "laboratory medicine", the laboratory is no longer the previous auxiliary departments, and its gradual clinical correlation, has become an independent discipline. Medical testing is a scientific and modern physical and chemical knowledge and means to carry out medical diagnosis of the discipline, its main research on how to use scientific experimental techniques and advanced equipment to provide the basis for clinical diagnosis and treatment. Medical testing involves basic medicine, biochemistry, clinical medicine, management and many other subjects, the use of these disciplines can quickly and accurately provide a diagnosis of the disease is indeed the basis of modern medical work is indispensable to a link.
First, the development of China's laboratory medicine
In recent years, China's clinical medical testing education has been rapid development, the early 1950s, China will be in the junior college health school opened a medical testing specialty, which is used to cultivate the primary, intermediate medical testing-related personnel. 1983, there have been a succession of medical testing in the higher medical schools set up undergraduate medical testing. In 1983, there were successively set up in the higher medical school undergraduate medical testing program, and for China to train a large number of medical testing-related higher education personnel. Until now, China's medical testing personnel training system has been completed, forming a set of professional training channels. Now has formed a clear goal, with a general test specialist, master's degree and doctoral degree (medical science degree), seven-year master's degree (medical degree), adult test specialist, senior test specialist and other levels of complete and varied forms of education system. This perfect talent training system for China's clinical testing medical careers to train a large number of outstanding talent, and make the basic quality of clinical testing personnel to get a piece of the general improvement.
China's quality control management system started late, but some disciplines as well as the formation of a more reasonable quality control system. At present, pre-analytical quality control, analysis of quality control and post-analytical quality control have achieved a certain degree of good development, which has been able to basically ensure the accuracy and comparability of the results. At the same time, with the deepening of reform and opening up and economic growth, China is also vigorously using international information technology exchanges, learning and the introduction of advanced professional technology and testing equipment from developed countries.
Second, the main problems in China's clinical medical testing
2.1, unreasonable resource management: At present, many hospitals do not do a good job of resource management, which is embodied in the following specific: the staffing is not reasonable (there are some positions in the configuration of the staff is too much or too little) and medical equipment is not reasonable. Irrational allocation of personnel has led to the loosening of the test team, each other can not form a strong cooperation, the test process there are misuse and unreasonable, resulting in errors in the test results. And this unreasonable allocation of human resources will also bring some problems, such as duplication of staff equipment in the same hospital will cause a waste of resources; due to the dispersion of staffing, but also makes the whole system is not unified management, so that the hospital staff can not improve the quality of business.
2.2 Theoretical system of laboratory medicine is incomplete: Although in recent years China's clinical medicine has made great progress, but the development of China's medical testing field in the development of the main focus on the construction of hardware, more inclined to the replacement of the equipment, but ignored the theory of the degree of importance for the laboratory medicine. At present, China's medical testing can only be regarded as "experimental medical testing" which has not yet formed a set of perfect, new theoretical system. For medical testing issues on the low capacity of scientific research, the innovation of the relevant personnel (scientific research) awareness is weak, this phenomenon has hindered the good development trend of laboratory medicine.
2.3 Quality control is not in place: there is no good quality control will not only affect the accuracy of the test results, but also may mislead the clinical diagnosis and treatment, to the patient's health, serious and even endanger the patient's life. Quality control work in any case must pay attention to, but part of the test personnel because of the development and application of modern equipment, began to gradually dilute the importance of quality control work.
Three, the future development trend of clinical medical testing
3.1 Improve the quality of personnel: China's test medicine is moving towards informationization, automation. So we should be based on the needs of society and the development of laboratory medicine to train high-quality testing personnel to adapt to the new era. First of all, clinical medical testing inspectors must have a solid professional foundation, including basic knowledge of clinical medicine, physical chemistry and other related knowledge. Secondly, clinical laboratory personnel must have professional equipment operation skills, equipment operation standards can affect the accuracy of the test results. Finally, in education should also be guided by efforts to broaden the knowledge of clinical laboratory personnel. Can not be limited to the knowledge of the specialty, but also other related knowledge should be understood.
3.2 Strengthen the construction of information technology: the new era is the era of information technology, information technology is the development trend of the new century, many industries are using information technology, and has achieved good development. In the field of clinical medical testing to establish the collection and processing of information to achieve the purpose of information *** enjoyment of the information system has been an inevitable trend. Its main performance in the laboratory will use more automated ways to transmit test results, and through the computer Internet will be transmitted to the laboratory and clinical results, and even the realization of hospitals and hospitals, the city and the city and the international exchange of information. Resources **** enjoy, promote communication and cooperation between the industry and so on.
3.3 to the development of automation: at this stage, most of the domestic test departments of various types of automated analytical instruments are single-machine automation, while the trend of the development of testing instruments in developed countries is to connect the connected machines in series to form a kind of assembly line operation, that is, automation. Therefore, in order to improve the efficiency of the test work and test results, we must also be on par with the developed countries to realize the automation of the test. With the development of computer technology and the improvement of modern laboratory science, many of the previous manual test subjects are now gradually replaced by automated instruments, the speed of the test and the number of test items are much higher than in the past. This is China's future medical testing work in the development trend of equipment.
Background and significance of the topic
Background
Background of the topic
Over the past few decades, in the planned economic system, China's health care services are the scope of the welfare; the marketization of health care services is in the macro-market-oriented reforms to promote. With the deepening of the reform of the health care system, it is an indisputable fact that medical services have the nature of the market. After joining the WTO, the medical market is gradually opening up, the rapid rise of private hospitals, the establishment of Sino-foreign joint venture hospitals, the medical market competition is becoming increasingly fierce.
As the capital city of the province, Zhengzhou, in addition to the provincial and municipal levels of medical institutions, there are many different kinds of . Specialized hospitals and specialist clinics, in recent years, Zhengzhou City, the health care industry is entering a rapid development stage, the current total number of hospitals has reached more than 300.
During her junior year of study, the author undertook a study of service marketing management in hospitals of traditional Chinese medicine in Henan Province, and this paper analyzes the problems and coping strategies of service marketing in hospitals from the perspective of the service quality gap model.
Significance of the topic
Reality
Through the survey of 200 patients' satisfaction with the services of the hospital of traditional Chinese medicine in Henan Province, analyzing the six aspects of the medical environment, technical level, service attitude, service efficiency, service charges, medical ethics and morals, and so on, we objectively and fairly Collecting patients and their families on all aspects of the hospital's opinions and suggestions, so as to provide a feasible basis for departmental assessment, hospital management and development.
Theoretical significance
Henan Provincial Hospital of Traditional Chinese Medicine, as a modern, comprehensive, third-class hospital integrating medical treatment, teaching, and scientific research, is in the upstream of Zhengzhou's healthcare industry, and through the analysis of its Service Quality Gap Model, it is possible to explore the reasons for the gap in quality of service and to seek countermeasures to make every medical worker establish a strong sense of market value. By analyzing its service quality gap model, exploring the causes of the service quality gap, and seeking measures to cope with it, every medical worker can establish a strong sense of market, service, competition and marketing, and establish a medical service marketing model in the whole hospital, which will not only be an improvement to himself, but also make due contribution to the development of other hospitals in Henan Province.
Summary of relevant domestic and foreign research
At present, the following three models are more popular in the international arena, of course, in the field of service marketing, these three theoretical models are not exhaustive, other scholars have also put forward a lot of other theoretical models, but these three are the most influential and representative of the significance of the three models, because these models without exception will focus on the research of the face-to-face service experience. They are the most influential and representative because they all focus on the face-to-face service experience.
Service experience and its components
Any service experience consists of four elements: 1) service employees; 2) service facilities; 3) service customers; 4) service process. Although all kinds of service experiences include these four elements, the extent to which the four elements contribute to the service experience varies from service to service. For example, in some service experiences, employees play a less important role, such as movie theater staff have little impact on the audience's enjoyment of the film relative to dentists.
Employees include both those who are in direct contact with the customer (e.g., waiters, cashiers, etc.) and those members of the organization who are out of the customer's line of sight but also contribute to the delivery of the service (e.g., cooks, bank accountants, etc.). Service facilities include both those that are accessible to the customer, (e.g., restaurants, bank lobbies, etc.) and those that are generally rarely approached by the customer (e.g., restaurant kitchens, bank safes, etc.). Customers are the recipients of the service (e.g., diners, depositors, etc.) and those with whom they *** enjoy the service facilities. Finally, the service process is the sequence of activities (i.e., the various actions taken by the customer and the service organization while dining or depositing) engaged in to provide the service.
All four components of the service experience play an important role in shaping the service experience. However, not all components of the service experience are equally important in shaping the service experience for different service interactions. To accommodate these special cases, any framework for analyzing service experiences should allow for differences in the importance of the components.
Service Marketing Mix Theory
The marketing mix refers to an organization's ability to identify controllable marketing factors and determine the optimal mix of marketing factors based on customer needs. Early marketing theories were almost exclusively driven by the marketing mix concept. Of the many ideas about the marketing mix, the most influential is the 4P's marketing mix, in which the 4P's are product, price, promotion, and place. Booms and Bitner (1981) suggest that for service organizations, the 4P's should be supplemented by three additional marketing factors, namely, participant (p) and place (p). Booms and Bitner (1981) suggested that for service organizations, three additional marketing factors should be added on the basis of the 4P's, i.e., participants, physical evidence, and process of service assembly, so the service marketing mix is based on the traditional 4P's and the 3 P's mentioned above. The 3P's newly added to the service marketing mix capture the essence of service marketing and point out that the service marketing mix is the most important part of service marketing. The new 3P's in the service marketing mix captures the essence of service marketing, points out the difference between service products and tangible products, and provides us with a theoretical model to analyze the service experience and its components.
Participants are all the people involved in the process of producing a service, including not only customers but also employees. Tangible evidence refers to the service environment and other tangible aspects of the service. The service assembly process is the set of activities and the sequence in which they occur in order to provide the service. For any service, each newly added marketing factor affects the customer's overall perception of the service. Therefore, organizations intending to expand their service business for specific market segments can adapt one or more of these marketing factors to the characteristics of their target customers in order to highlight the service characteristics. Service distinctiveness can be derived from tangible evidence. Similarly, a service organization can differentiate its services by adapting its service players. As with the traditional 4Ps, there are multiple linkages between the newer 3Ps. Reinforcing one of these marketing factors to influence customer perceptions may require or trigger changes in other marketing factors.
In summary, the service-marketing mix model recognizes the incorporation of three new marketing factors that are important when marketing a service. One of the strengths of the service marketing mix model is that it builds on the more established marketing concept of the marketing mix, highlighting the orthodoxy of the theoretical model and emphasizing the differences between marketing services and marketing tangible products.
The Service Theater Model
Comparing a service to a play, the Service Theater Model (Grove and Fisk, 1983, 1992) has the same constituent elements as a stage product: actors, audience, facilities, front of house, back of house, and performance.
Research Content, Focus and Difficulties

Research significance:
Neonatal necrotizing enterocolitis (NEC) is a serious life-threatening gastrointestinal emergency in the neonatal period, which is more common in preterm infants and infants younger than the gestational age, and the incidence rate is as high as 10% in children in the NICU, and it is one of the most important causes of preterm infant mortality. Clinical bloating, diarrhea, mucous blood stools and bile-like vomiting as the main manifestations, abdominal X-ray film is characterized by cystic pneumatosis of the intestinal wall, the scope of intestinal lesions can be confined or extensive, the ileum is the most involved, the mucosa is coagulative necrosis, the submucosal layer of the diffuse hemorrhage or necrosis, and in severe cases, the entire intestinal wall is necrotic or even perforated.
Currently there are many methods used to diagnose NEC, in addition to the diagnosis can be based on clinical manifestations, abdominal X-ray is the most commonly used auxiliary examination methods, although its specificity for the diagnosis of NEC is high, but for the early diagnosis of NEC is not very helpful, there are also many studies on the use of biochemical indicators, such as IL-8, IL-10, IL-1 receptor antagonist, etc., to diagnose NEC, but the lack of better for the early diagnosis of NEC. there is a lack of better blood biochemical indicators for early diagnosis of NEC.
TLR is a protein similar to the Drosophila Toll protein found in mammals by Nomuria et al. The expression of TLR in different cells and the recognition of different cytokines play an important role in the pathogenesis of many diseases, and current research has found that TLR is involved in the pathogenesis of many diseases such as tumors, intestinal immune diseases, and so on. There are 10 members of the TLR family*** found in humans, of which TLR4 is one of the more studied ones in recent years, and TLR4 is mainly expressed on endothelial cells, macrophages, neutrophils and DCs.
I-FABP is a small molecule protein secreted by monolayer columnar epithelial cells of the small intestine, accounting for 2% of mature cellular matrix proteins. Early intestinal ischemia with only mucosal involvement can result in the release of IFABP into the bloodstream due to elevated cell permeability, which has good organ specificity.
The aim of this study was to detect TLR4 and intestinal fatty acid binding protein in the serum of children with NEC and monitor their dynamic changes in NEC as a biochemical indicator of the severity of NEC, which can provide the basis for the adjunctive diagnosis of NEC and achieve the purpose of early intervention.
Analysis of the current status of domestic and overseas research:
Mechanism study of TLR4 upregulation leading to NEC occurrence
After binding to LPS, activated TLR4 can mediate the release of inflammatory factors through both Myeloid Differentiation Factor 88 (MyD88)-dependent and non-dependent pathways. Among them, the MyD88-dependent pathway mainly mediates NF-kB activation and cytokine production, whereas the non-dependent pathway of MyD88 mainly induces the expression of interferon (IFN), as well as interferon-inducible protein 10 (IP10) gene, glucocorticoid attenuated response gene 16 (GARG-16), and interferon-regulated gene 1 (IRG-1) of LPS, and the maturation of DCs that Activation of downstream NF-kB, c-Jun amino-terminal kinase (JNK), and mitogen-activated protein kinase (MAPK) p38 signaling pathways induced the expression of pro-inflammatory factors, such as interleukin-1 (IL-1) 6, 12, and tumor necrosis factor-alpha (TNF-α).
Chan et al. found that TLR4 activation affects the repair capacity of intestinal mucosa, which is related to the reduction of intestinal cell proliferation, the reduction of basal adhesion of endothelial cells, and the reduction of the number of endothelial cells to move to the damaged site.
Sodhi et al. demonstrated that TLR4 inhibits the wnt-β-5 signaling system by inhibiting cell proliferation and differentiation, which impairs the repair capacity of intestinal mucosa and aggravates the disease of NEC. capacity is impaired, exacerbating the pathologic changes of NEC.
Recent studies have shown that TLR4 not only binds to LPS to induce an inflammatory response and damage the intestinal mucosa leading to the development of NEC, but also that many molecular proteins such as fiber-binding protein, hyaluronic acid, and heparan sulfate can activate TLR4. Heparan sulfate, etc. can activate TLR4, and TLR4 expression may increase in the absence of foreign pathogens, releasing a large number of inflammatory factors thus the inflammatory waterfall chain reaction of NEC occurs. This finding may explain some NEC caused by no obvious infectious factors.
How bacteria and their products cause damage to intestinal epithelial cells is explored
Platelet-activating factor (PAF) plays an important role in the development of NEC. Some studies applied hypoxia, low temperature, artificial feeding, bacterial infection and other methods to make an animal model of NEC, the results found that the intestinal epithelium of PAF and its receptor expression increased, blocking the receptor expression of PAF after the incidence of NEC decreased significantly.Increased expression of PAF can make the intestinal wall vascular permeability increased, leukocytes, leukocytes, cell adhesion molecules synthesis and reactive oxygen species production increased, thus damage to the intestinal wall. PAF can increase the vascular permeability of the intestinal wall. Some studies have shown that PAF can activate the STAT of intestinal epithelial cells, increase the synthesis of phosphodiesterase A2 and endothelin I1, and induce apoptosis of intestinal epithelial cells through the expression of bax, thus damaging the intestinal epithelial cells and destroying the connection of cells, and causing bacterial translocation. In addition, PAF induces the production of TLR4 in IE cells, which can activate IKK, thereby activating NFxB and causing an inflammatory cascade. If TLR4 was knocked down, the incidence of NEC was significantly reduced, suggesting that TLR4 also has an important role in the development of NEC.
Shen Duihua et al. showed that I FABP can be used as a better biological indicator of early intestinal ischemia, and foreign scholars have found that the serum I-FABP level of children with NEC is significantly elevated and correlated with the severity of NCE.
Thuijls et al. found that serum I-FABP levels were significantly elevated in children with severe NEC at an early stage. When mild abdominal distension and positive fecal occult blood were clinically suspected in NEC,
blood and urine I FABP levels were significantly higher in children who developed severe NEC
than in those diagnosed with other diseases and those whose condition was stable at NEC stage I or II.
Medical Opening Paper Part 5Analytical chemistry is a very practical specialty, so the experiment occupies an important significance in it.
Teaching cannot be carried out without experimental teaching, in the experimental teaching to learn more practical knowledge, hands-on ability and practical ability will also be enhanced. With the development of science and technology, a large number of new instruments and testing techniques have emerged, the medical testing profession on the hands of students will be more and more demanding, students only at the same time both high experimental skills, high theoretical level, the ability to independently design medical experiments as well as strong analytical skills in order to become the era of the need for medical testing personnel. Therefore, in the daily teaching activities of medical testing, we need to pay attention to experimental teaching, the use of experimental teaching to improve the overall quality of teaching, so that medical testing students in the mastery of solid theoretical knowledge and at the same time access to practical opportunities to enhance practical skills. In addition, it should be noted that in the teaching process, teachers also need to correct the students only pay attention to the medical part of the content of the chemical part of the content of the incorrect thinking, comprehensive consolidation of basic knowledge, so as to avoid the knowledge of the loopholes and affect the effect of experimental teaching.
Measures to strengthen the teaching effect of analytical chemistry in medical testing:
1, in terms of teaching content, seize the key, actively summarize and generalize.
Medical testing students in the study of analytical chemistry before they have studied the relevant medical basic chemistry courses, teachers only need to comb the teaching content once students will be clear about their weak and need to master the place. Then the teacher can focus on the key content to explain, saving teaching time. Analytical chemistry involves content including mathematical statistics and chemistry, are more complex content, and there will be more formulas. Therefore, teachers in the teaching process need to be good at generalization, will be similar to the content summarized together, so that students can remember the key content faster. For example, in the calculation of the distribution coefficient of the weak acidic system, the formula involved is more complex, the teacher can find out a convenient way for students to memorize through the discovery of the law: the denominator of the formula is in accordance with the order of the concentration of hydrogen ions in the order of the power of the molecule depends on the number of hydrogen contained in the type of body. By capturing this pattern, students can memorize the formula more quickly and y.
2. In the teaching mode, a combination of teaching modes to enrich the classroom.
In the teaching mode, teachers can ensure the quality of teaching on the basis of strengthening the interaction with students. Lecture-based, combined with talk, questions, essays and exercises and other auxiliary means to make students' thinking the center of teaching, stimulate students' creative thinking, so that students feel the joy of learning and gradually make progress. First of all, the teacher can start from the solution transfer, balance weighing operation method, etc. to teach, in combination with the experimental class based on the cultivation of students on the accuracy of the test results of the importance of. Secondly, after a part of the knowledge is finished, teachers can use the way of questioning to strengthen the students' memory of the knowledge points, and let the students get a sense of achievement in the process of quizzing, and stimulate their enthusiasm for learning analytical chemistry. Again, the teacher can determine a topic according to the students' knowledge mastery, and let the students talk about the topic and communicate with each other. Students in the exchange process can not only see the gap between themselves and their classmates can clearly recognize their own shortcomings, and then targeted for intensive training. Discussion of the development of teaching can also improve the participation of students in the teaching process, so that students become the main body of teaching, in the process of activities to play a subjective initiative, more active, active learning.
