Objective To explore the application effect of C-reactive protein combined with blood routine and blood culture in the diagnosis of bacteremia. Methods In this study, 69 patients with suspected bacteremia examined from May 2023 to May 2024 were selected as the observation group. In order to more intuitively understand the application value of the three combined detection methods, 69 healthy patients in the same period were selected as the experimental group. Analysis of blood routine indexes, strain distribution in blood culture and C-reactive protein detection data in both participating groups. Results In the blood cultures. Results A total of 8 strains were detected in the blood culture of 69 suspected bacteremia patients in the observation group. Among the two strains with high detection rate, except gram-negative bacteria and gram-positive bacteria, the two strains with the highest detection rate were staphylococcus 25 strains. Escherichia coli 16 granules, and 16 E. coli with detection rate of${23.19}\%$. WBC$\left({{15.45}\pm {2.18}}\right)\times {10}^{9}/\mathrm{L}$, NEU$\left({{81.24}\pm {2.84}}\right)\%$, LYM$\left({{53.24}\pm {2.68}}\right)\%$, C-reactive protein levels (53.24±2.68) mg/L, WBC (6.45±1.28)×10${}^{9}$/L, NEU (62.41±2.34)%, LYM (26.45±2.18)%, and C-reactive protein levels$\left({{6.28}\pm {1.25}}\right)\mathrm{{mg}}/\mathrm{L}$. WBC, NEU, LYM and C-reactive protein levels in patients with suspected bacteremia in the observation group were significantly higher than those of healthy patients in the experimental group$\left({P <{0.05}}\right)$. Of the 69 suspected bacteremia, 66 were positive and 3 were negative. Among them, 63 cases were positive in blood culture, 58 cases were positive in blood routine test, 56 cases were positive in C-reactive protein test, and 66 cases were positive in C-reactive protein combined with blood routine and blood culture test. Among the four detection methods, C-reactive protein combined with blood routine and blood culture test were no different with the confirmed results. Conclusion In clinical diagnosis and detection of suspected bacteremia patients, C-reactive protein combined with blood routine and blood culture can maximize the accuracy of detection data, and the combined diagnosis of the three is of higher clinical value.

Objective To improve the determination of free silica content in dust by pyrophosphoric acid heated by silicon carbide in order to ensure the accuracy of detection. Methods Analyze the influencing factors and controls during the experimental process, including the determination of dust sample composition, sample processing, preparation of pyrophosphate, control of heating temperature, hot filtration, ashing and weighing. Results By controlling and improving the influencing factors during the experimental process, measurement errors can be effectively avoided. Conclusion The importance of determining the characteristics of dust samples during the measurement process lies not only in the preparation of pyrophosphate and strict temperature control, but also in the accuracy of data analysis for quality control sample analysis.

The safety of university laboratories is a fundamental guarantee for promoting the continuous development of education and scientific research, and for teachers and students to carry out work and study smoothly. In China's vigorous promotion of the construction of "Double First Class” universities, the existing management methods and personnel configuration are unable to meet the current national requirements for laboratory safety management in universities. Building a scientific, comprehensive, practical, and easy-to-use laboratory safety management platform is an important issue that universities urgently need to study and solve. This article analyzes the necessity of building a laboratory safety management platform in universities under the current information technology background. Based on the actual work of Xinjiang University, a laboratory safety management system construction plan is proposed, and the system operation effect is analyzed to achieve systematic and intelligent management of the laboratory. It has played a positive role in supporting the cultivation of innovative talents and standardizing laboratory management, and has achieved certain results.

Based on the current status of university laboratory culture construction, this paper deeply analyzes the existing problems. Drawing on the concept of the management model of EHS (environment, health, safety) in management science, a generalized EHS model applicable to the management of university laboratories is proposed. Furthermore, an evaluation index system model (seven-force diagram) for laboratory safety culture construction is constructed based on the AHP (analytic hierarchy process) method, which can effectively enhance experimental safety and ensure standardized management of university laboratories.

Methods The zero calibration method based on Prolink industrial control software was used to measure and zero the CMF mass flowmeter, and data on indication error and repeatability were obtained. Results Before zeroing, the reading error of the Coriolis mass flowmeter was measured to be -0.85%, and it was calculated that there was zero drift. After zero calibration, the indication error of the flowmeter is -0.12%, and the measurement performance meets the requirements of the accuracy level. Conclusion After using Prolink industrial control software to adjust the zero value of the flowmeter, the influence of zero drift on the phase difference offset of the flowmeter can be eliminated, thereby improving the measurement accuracy of the flowmeter.
