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.

The development of intelligent sensor technology has brought revolutionary changes to all walks of life, especially in the field of industrial production and textile testing to show great potential. Smart sensors are not only capable of sensing physical or chemical quantities in the environment, but also have data processing and intelligent analysis capabilities, making them a significant advantage in textile defect detection. This paper analyzes the basic principle, characteristics and application status of intelligent sensor in industrial production and textile testing. The applications and advantages of different types of intelligent sensors, such as vision, infrared and ultrasonic systems, in textile production are analyzed.

Objective To analyze the effectiveness of enzyme-linkedimmunosorbent assay (ELISA) and colloidal gold test in the detection ofhuman immunodeficiency virus (HIV) antibodies. Methods From January 2022to January 2024,50 cases of sentinel surveillance and contact populationof confirmed AIDS patients in our unit were selected as the observationtarget, and they were detected by ELISA and colloidal gold testrespectively, and the difference of patients’ detection results wasanalyzed. Results Among the 50 key populations, 36 were ultimatelydiagnosed and 14 were negative, which is the gold standard for thisstudy. The diagnostic effect of enzyme-linked immunosorbent assay issignificantly better than that of colloidal gold assay, and thedifference is statistically significant $\left({P <{0.05}}\right)$ . Conclusion The enzyme-linked immunosorbent assay (ELISA) is significantly moreeffective in HIV antibody detection than colloidal gold assay, and isworthy of being the preferred detection method.
