College pharmacy teaching laboratory is an important place to train pharmaceutical technology practical talents, involving many disciplines, equipment and chemicals, which will bring a large number of unsafe factors, and a little carelessness will cause personal, property and environmental safety accidents. Therefore, safety management should be strengthened. Based on the practice of laboratory safety management, this paper analyzes the current situation and problems of safety management, and believes that it can be improved from the aspects of safety system, safety education, hardware construction and targeted management of each laboratory, so as to effectively improve the safe operation of the laboratory.

The gas chromatograph uses gas as the mobile phase, and the sample to be measured is brought into the column by the carrier gas after gasification in the gasification chamber, and the components are separated in the column and detected by the detector. The baseline is the comprehensive performance of the performance of the gas chromatograph in operation, and the failure of each part of the instrument, the change of operating conditions and external conditions and other factors will be reflected on the baseline, so the cause and location of the fault can be judged according to the baseline.

Objective To investigate the content of pesticide residues and exogenous heavy metal pollutants in 10 commonly used Chinese crude drugs (Morindae officinalis radix; Citri grandis exocarpium; Polygoni multiflori radix; Amomi Fructus; Pogostemonis Herba; Baphicacanthis Cusiae Rhizoma et Radix; Radix Kadsurae Coccineae; Bruceae Fructus; Arecae Semen; Alpiniae Oxyphyllae Fructus) from 200 batches from different regions in Lingnan, in order to provide a basis for quality control of southern medicine. Methods The content of the exogenous pollutants such as heavy metals, harmful elements, pesticides in 10 commonly used Chinese crude drugs was measured according to Pharmacopoeia of The People's Republic of China (2020 edition)(hereinafter referred to as Chinese Pharmacopoeia), in order to determine and analyze the measurement results. Result The pesticide residues and limits of lead, arsenic, cadmium, mercury, and copper in Polygoni multiflori radix, Baphicacanthis Cusiae Rhizoma et Radix, Radix Kadsurae Coccineae, Arecae Semen and Alpiniae Oxyphyllae Fructus all meet the requirement of the Chinese Pharmacopoeia. Morindae officinalis radix, Citri grandis exocarpium, and Amomi Fructus all have heavy metal non-compliance, while Pogostemonis Herba has pesticide residue non-compliance. Conclusion For the studied varieties, pesticide residue control is good, and it is necessary to focus on monitoring lead and mercury elements.

College electrical and electronic laboratories play a crucial role in conducting fundamental and advanced education and teaching activities. In order to improve the overall safety of electrical and electronic laboratories in colleges and universities, eliminate safety hazards and prevent safety accidents. This paper analyzes and summarizes the common unsafe factors in electrical and electronic laboratories in colleges and universities. These unsafe factors include physical unsafe factors and human unsafe factors. Physical related unsafe factors involve experimental equipment and experimental environment, while human related unsafe factors involve laboratory managers, experimental instructors and students. Based on an analysis of these unsafe factors, this paper puts forward specific measures for electrical and electronic laboratory safety management, including strengthening the safety management of experimental equipment and experimental environment, improving the safety management level of laboratory staff, enhancing the awareness of safety responsibility of experimental instructors, and eliminating unsafe behavior of students. These measures provide a certain security guarantee for the construction and development of electrical and electronic laboratories.

This article summarizes the non-destructive testing techniques for concrete structures and their importance in evaluating the durability of concrete. With the aging of infrastructure, the demand for rapid and accurate evaluation and maintenance of concrete structures is increasing. Non destructive testing technology is highly valued for its ability to provide accurate evaluations without damaging the structure. The article introduces the main non-destructive testing methods, including ultrasonic testing, electromagnetic wave testing, and radiometric testing, and discusses in detail the application effects of these technologies in practical engineering. The advantages and disadvantages of each technology were also compared and analyzed. In the future, with the development of intelligence, integration, and portability, non-destructive testing technology will further improve detection efficiency and accuracy, and be widely used in long-term monitoring of infrastructure, providing technical support for extending the service life of structures and reducing maintenance costs.

Objective To evaluate the performance of HORIBA ABX Yumizen H550 automatic blood cell analyzer. Methods According to the national health industry standard Quality Requirements for Analysis of Routine Items in Clinical Hematology Examination (WS/T 406-2012), the automatic blood cell analyzer was evaluated for background counting, carrying contamination, in-batch precision, linearity, accuracy, comparability of results in different suction modes, and comparability of results in the laboratory (the reference instrument was Sysmex XS800i automatic blood cell analyzer). Results The detection values of background count of all items of the automatic blood cell analyzer were met the requirements of industry standards and manufacturer’s instrument manuals, and the carryovers of white blood cell (WBC) count, red blood cell (RBC) count, hemoglobin (HGB) and blood platelet (PLT) count of that were all passed. The results of within-run precision and inter-day precision were less than the requirements of the specifications of instrument and were far less than the requirements of standard WS/T 406-2012. Within the linearity range, the slopes of the linear regression equation were within the range of$1 \pm {0.05}$. The correlations coefficient(r)of these equations were larger than 0.975 . The pass rate that the results compared with that of Sysmex XS800i were larger than 80%. The compared results of intra clinical laboratory indicated the trueness of instrument, the outcome bias between different suction patterns. Conclusion Yumizen H550 automatic blood cell analyzer has favorable performance, accurate and reliable results. It’s an ideal automatic blood cell analyzer.
