It is helpful to improve the standardization and effectiveness of biological laboratory safety management.

Objective To improve the detection method of bulk densityof powder materials, in order to improve the accuracy and efficiency ofthe detection results of cement. Methods Through the improvement ofauxiliary metal rod rotation technology at the pipe to loosen thematerial and make it fall naturally, the detection data before and afterthe improvement of cement volume density detection technology werecompared to find a more environmentally friendly, faster and accuratetest method. Results The improved test data did not fluctuate due to theequipment displacement, and the cement bulk density remained at ${1.03}\mathrm{\;g}/{\mathrm{{cm}}}^{3}$ inthe loose state, the whole test process took a short time ( ${1.5}\mathrm{\;{min}}$ ), there was no dustin the test process, and the test results did not exceed the errorrange, all of which were better than the measured data before theimprovement. Conclusion The improved test method can improve theaccuracy and precision of cement performance test more scientifically,and can make the test results closer to the real value, which isfeasible, has certain social and economic value, and is worthpopularizing.

Objective To analyze and discuss the influence of qualitycontrol on clinical laboratory results under the management of clinicallaboratory control, and to clarify the effective value of qualitycontrol in clinical laboratory. Methods A total of 80 patients who werecompletely registered in our hospital from January to August, 2023 andreceived medical examination were selected for a controlled study. Thepatients in the control group were treated with routine qualitymanagement methods, while the patients in the research group weretreated with quality control methods. Compare the qualified rate,satisfaction and examination results of nursing staff in the two groups,and collect the reasons for the unqualified examination results andevaluate them. Results Compared with the qualified rate of patients, theoverall qualified rate of the study group was ${97.5}\%$ , which was significantly higherthan that of the control group (85%), with statistical significance $\left({P <{0.05}}\right)$ .Compared with the patients’ satisfaction degree, the overallsatisfaction degree of the study group was 97.5%, which wassignificantly higher than that of the control group (72.5%), withsignificant difference (P<0.05). Compared with the examinationresults of nurses in departments, the patient education ability, samplecollection ability and sample processing ability of nurses in the studygroup were $\left({{89.91}\pm {4.56}}\right)$ points, $\left({{89.52}\pm {5.11}}\right)$ pointsand $\left({{88.88}\pm {4.44}}\right)$ points,which were significantly higher than those in the control group, withsignificant differences $\left({P<{0.05}}\right)$ . Conclusion Doing a good job in qualitycontrol and optimizing clinical medical examination can significantlyimprove the quality of hospital clinical examination, improve patients’satisfaction, improve clinical nurses’ cognition of clinical medicalexamination and enhance their clinical practice ability, which has highclinical application value and can be widely popularized.

Objective To investigate the disintegration and dissolutionproperties of alprogesterone as a feed additive under differentenvironmental conditions, and to develop a suitable tablet for pig farmfeeding. Methods The prescription was screened by 3-factor and 3-levelorthogonal test, and the disintegration time, dissolution and appearancequality of the tablets were tested. Results The disintegration time ofthe optimized allyl gestrel was $7\sim {15}\mathrm{\;{min}}$ , which was better than $2 \sim 5\mathrm{\;{min}}$ of conventionaltablets. Conclusion The optimized dissolution and content of allylgestrel meet the standard, which is convenient for sows to consume andcan meet the feeding needs of pig farms.

Objective To determine the content of inorganic arsenic inshellfish and aquatic products by high performance liquidchromatography-inductively coupled plasma mass spectrometry, and toevaluate the food safety according to the content level of inorganicarsenic. Methods Four kinds of shellfish products were randomlypurchased from local markets and extracted by soaking in acid solution.After separation and filtration, the content of inorganic arsenic in theextracted solution was determined. Results The average inorganic arseniccontent of the 4 kinds of shellfish products were 0.067 ~0.140 mg/kg forPaphia undulata, 0.120 ~0.470 mg/kg for clam Philippines, 0.061 ~0.140mg/kg for clam white, and ${0.056}\sim {0.190}\mathrm{{mg}}/\mathrm{{kg}}$ for Sinonovacula constricta, respectively. The highest content ofinorganic arsenic was found in Philippinarum clam. Conclusion Thecontent of inorganic arsenic in shellfish products sold in Foshan Cityin 2023 does not exceed the limit value of ${0.5}\mathrm{{mg}}/\mathrm{{kg}}$ ofChina’s national food safety standard. Common shellfish aquatic productsare generally safe to eat. However, it is still necessary to be cautiousabout eating high-risk shellfish products and pay attention to thoroughcooking and processing. At the same time, it is necessary to strengthenthe awareness of food safety, strengthen the supervision and managementof such aquatic products, and carry out food safety knowledge publicityand health education.

Objective To optimize the conditions for the determinationof total $\alpha$ and total $\beta$ radioactivity in drinking water andimprove the accuracy of the experiment. Methods On the basis ofmeasuring the residue content in drinking water, the total $\alpha$ and $\beta$ radioactivity values in drinkingwater were determined by improving evaporation and concentration processand optimizing reagent conditions. Results In this study, the amount ofresidue, $\alpha$ and $\beta$ radioactivity increased, and thetest time was reduced compared with the traditional method. Conclusion The method significantly improves the accuracy of results and testingefficiency and can be further optimized. It provides certain researchsignificance in the quality control of laboratory measurements.

With the continuous increase in the number and scale of university laboratories, traditional management models face many drawbacks such as low efficiency, resource waste, and safety hazards. In order to address these drawbacks, artificial intelligence technology has gradually been introduced into the intelligent management of university laboratories. This article aims to explore the application of artificial intelligence in the management of university laboratories, analyze its role in resource optimization, security management, equipment maintenance, and data analysis, and promote the better application of artificial intelligence in the intelligent management of university laboratories.

The large-scale instrument sharing platform in universities is the core resource for sharing scientific and technological resources. It not only provides strong support for teaching and research in various universities, but also offers technical support to relevant enterprises and other social units. After analyzing the current large-scale instrument sharing platforms in universities, it was found that there are problems in the service process. Based on the development of service plans, the construction of experimental teams, cross institutional cooperation mechanisms, and service quality evaluation and monitoring mechanisms, a “one-stop" service system guided by "demand" was proposed to optimize the entire service process, promote the improvement of sharing benefits, and form a closed-loop management.
