ABSTRACT: The inspection, testing and certification (TIC) industry is a basic system to strengthen quality management and improve market efficiency under the condition of market economy, and is a "trust hub" for both sides of the trade. With the liberalization of the CCC system, capital forces gradually entered, private enterprises malicious competition, industry leaders began to enter the acquisition and merger mode, and the domestic TIC industry gradually entered the "integration period". This paper aims to discuss the development strategy of TIC plate under the new situation. Firstly, starting from the development trend of TIC industry, the development status of TIC industry at home and abroad is comprehensively analyzed from many aspects such as market size, policy support and industry competition pattern. Secondly, it discusses the problems faced by TIC enterprises in the aspects of technology research, market selection, cultural adaptation and management standards under the background of globalization. Finally, combined with the above-mentioned problems, it deeply thinks about the future development planning and strategy of the whole TIC industry, and draws the conclusion that the future development of TIC plate needs to adhere to the industrialization of technical services. With the support of professional technology and platform operation, give full play to the role of talents, and build a two-way "hard and soft" strength with laboratory and public credibility.

Objective To study the method of laboratory Brucella detection and evaluate its clinical efficacy. Methods The clinical case of Brucella infection in sheep diagnosed by medical staff in our hospital in March 2019 was taken as the research object. The advantages and disadvantages of serum agglutination test, routine blood culture and bacterial identification, and mass spectrometry identification methods in diagnosing Brucella were analyzed and discussed, providing some reference for the detection of Brucella in grassroots hospital laboratories. Results The medical staff's serum brucellosis tiger red plate agglutination antigen test was positive. The blood culture BD PhoenixTM whole bacterial identification/drug sensitivity system instrument in the United States indicates that the aerobic bottle reports positive, but cannot identify the species of Brucella. The mass spectrometer identified it as Brucella lamblia. Conclusion The above methods have their own advantages and disadvantages in application, grassroots hospital laboratories should choose suitable methods for detecting Brucella based on actual conditions.

Material surface performance testing technology plays an important role in the research and application of chemistry, especially in university chemistry experimental teaching. These technologies provide students with opportunities to deeply understand the surface characteristics, structure, and chemical behavior of materials. This article focuses on the commonly used surface performance testing techniques for materials, such as scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), contact angle measurement, surface plasmon resonance (SPR), and Raman spectroscopy. It analyzes their practical applications in university chemistry experiments and their impact on improving students' experimental abilities and scientific research literacy. By introducing these advanced detection techniques in experimental teaching, not only can students enhance their understanding of the microstructure and chemical reaction mechanism of material surfaces, but they can also help them master the commonly used technical means in modern scientific research, laying a solid foundation for future scientific research work.

Objective To investigate the interference of calcium dobesilate on the urine total protein determination test kits (turbidimetric method) and the anti-interference method. Methods (1) According to the national standard WS/ T 416-2013 Interference Test Guide, low, medium, and high concentrations of urine matrix were used to prepare calcium dobesilate interference samples of different concentration gradients, and the urine total protein concentration was detected using the urine total protein determination test kits (turbidimetric method) of Dirui and Roche two factories. The relative deviation between the interference sample and the reference control sample was calculated.(2) The urine matrix was prepared at low, medium, and high concentrations, and the$0\mathrm{{mmol}}/\mathrm{L}$and$1\mathrm{{mmol}}/\mathrm{L}$calcium dobesilate interference samples were prepared using different wavelengths. The urine total protein concentration was determined using the urine total protein determination test kits (turbidimetric method) of Dirui and Roche two factories, and the relative deviation with respect to the${505}\mathrm{\;{nm}}$measurement wavelength was calculated. Results (1) When the calcium dobesilate concentration was${0.4}\mathrm{{mmol}}/\mathrm{L}$, the deviation of the urine total protein detection results in the low and medium concentration urine matrix began to deviate significantly from the acceptable interference range, and the degree of interference on urine total protein detection increased as the calcium dobesilate concentration increased. At the same drug concentration, the greater the urine total protein concentration was, the more obvious the interference was.(2) When the test wavelength was${800}\mathrm{\;{nm}}$, the interference of calcium dobesilate on the Dirui and Roche turbidimetric method urine total protein test kits could be significantly reduced, and the deviation of interference was within the acceptable interference range. Conclusion Calcium dobesilate can produce varying degrees of negative interference on the total protein determination assay (turbidimetry method), which should be taken seriously.

Objective To study the correlation between acute upper respiratory tract infection pathogenetic testing and traditional Chinese medicine (TCM) diagnosis and treatment, and to provide an objective basis for TCM diagnosis and treatment. Methods 316 patients with acute upper respiratory tract infection (AURI) admitted to our hospital between January 2023 and January 2024 were randomly selected as the study subjects, and the patients were subjected to blood routine examination and pathogen antibody examination to explore the relationship between patients' TCM diagnostic typing and patients' pathogen antibody examination. Results The percentage of viral infection in 316 AURI patients was 52.53%, mycoplasma infection was 6.01%, and bacterial infection was 5.06%. Acute upper respiratory tract infection (AURI) caused by adenovirus, parainfluenza virus, and syncytial virus infection was mainly characterized by wind-cold bundling of the surface syndrome in traditional Chinese medicine (TCM); Epstein-Barr virus (EBV) and coxsackievirus infection was mainly characterized by cold-heat intermingling syndrome in TCM; influenza virus infection was mainly characterized by wind-heat violation of the surface syndrome in TCM; bacterial, pneumonia, and mycoplasma infection were mainly characterized by wind-heat violation of the surface syndrome in TCM; and bacterial, pneumonia, and mycoplasma infection were mainly characterized by wind-heat violation of the surface syndrome. AURI caused by Mycoplasma infections was mainly characterized by wind-heat syndrome; AURI caused by viral and bacterial infections was mainly characterized by cold-heat syndrome. Conclusion There is a significant correlation between the TCM diagnostic typing of AURI caused by different pathogens, and the TCM diagnostic typing can effectively predict the type of infection of the patients and provide reasonable guidance for the clinical treatment of the patients.
