Infectious disease is a major public health problem threatening human health and social development, and infectious disease teaching is an important part of public health education. However, traditional infectious disease teaching faces challenges such as overly theoretical and fragmented content, overly traditional and monotonous methods, and a narrow and isolated vision, which makes it difficult to adapt to the current complex and changing situation of infectious disease prevention and control. The “One Health” concept emphasizes interdisciplinary, cross-sectoral, and cross-regional communication and cooperation to achieve the harmonious unity of health for humans, animals, and the environment, which is significant in preventing and controlling infectious diseases. This paper proposes some ideas for reforming infectious disease teaching based on the One Health concept, which aims to improve the quality and effectiveness of infectious disease teaching by recognizing the close connection between human health, animal health, and environmental health. Specifically, it is suggested to reform the teaching in four aspects: introducing the basic concepts, principles, and practices of One Health, increasing the content of infectious diseases related to One Health, adopting diversified and interactive teaching methods, and establishing cross-disciplinary teaching cooperation. Concrete recommendations are provided for each aspect. This paper argues that reforming infectious disease teaching based on the One Health concept is conducive to cultivating public health talents with global vision, systems thinking, and cross-disciplinary collaboration capabilities, providing robust talent support for coping with emerging, re-emerging, and endemic infectious disease threats.

Dynamic tracking analysis of monoclonal antibodies (mAbs) biotransformation in vivo is crucial, as certain modifications could inactivate the protein and reduce drug efficacy. However, a particular challenge (i.e. immune recognition deficiencies) in biotransformation studies may arise when modifications occur at the paratope recognized by the antigen. To address this limitation, a multi-epitope affinity technology utilizing the metal organic framework (MOF)@Au@peptide@aptamer composite material was proposed and developed by simultaneously immobilizing complementarity determining region (CDR) mimotope peptide (HH24) and non-CDR mimotope aptamer (CH1S-6T) onto the surface of MOF@Au nanocomposite. Comparative studies demonstrated that MOF@Au@peptide@aptamer exhibited significantly enhanced enrichment capabilities for trastuzumab variants in comparison to mono-epitope affinity technology. Moreover, the higher deamidation ratio for LC-Asn-30 and isomerization ratio for HC-Asn-55 can only be monitored by the novel bioanalytical platform based on MOF@Au@peptide@aptamer and liquid chromatography-quadrupole time of flight-mass spectrometry (LC-QTOF-MS). Therefore, multi-epitope affinity technology could effectively overcome the biases of traditional affinity materials for key sites modification analysis of mAb. Particularly, the novel bioanalytical platform can be successfully used for the tracking analysis of trastuzumab modifications in different biological fluids. Compared to the spiked phosphate buffer (PB) model, faster modification trends were monitored in the spiked serum and patients' sera due to the catalytic effect of plasma proteins and relevant proteases. Differences in peptide modification levels of trastuzumab in patients' sera were also monitored. In summary, the novel bioanalytical platform based on the multi-epitope affinity technology holds great potentials for in vivo biotransformation analysis of mAb, contributing to improved understanding and paving the way for future research and clinical applications.

Ultraviolet radiation affects human health. On the one hand, moderate amounts of UV radiation can promote human health and have the effect of promoting vitamin D production; but on the other hand, excessive UV radiation can also cause adverse effects on human skin and eyes, such as causing skin photoaging, skin cancer, electrophthalmia and cataracts to occur. Therefore, the measurement of ultraviolet radiation is extremely important. This paper mainly reviews the health effects of ultraviolet radiation and the progress of measurement standards in the workplace, and puts forward suggestions on the revision of the existing standards from five aspects including use new measuring instruments and methods, improve the existing measuring instruments, specify the number of measurements, expand the scope of application of the standards and consider the influence of the sun on the measurement of artificial ultraviolet radiation, so as to provide reference for the revision of new standards.

0.05). The MIP image should be used to select the optimal projection angle and measure the aneurysm, while the SSD image was for reference only. Conclusion SCTA can not only diagnose cerebral aneurysms accurately but also has high directive value in making therapy plan, surgical preparation and endovascular embolization.

Objective To evaluate the effects of percutaneous computed tomography-guided ethanol injection (PEI-CT) in adrenal benign functioning tumors. Methods Twenty cases of adrenal benign functioning tumors were treated by the therapy of PEI-CT. Among them, 5 cases were pheochromocytomas, and 15 cases were aldosteronomas. After the treatment, the change of blood pressure, aldosterone plasma levels, potassium plasma levels, and catecholamines urine levels was investigated. Both plain and enhanced CT scans were performed before and after the treatment to evaluate the changes of the size and necrosis in the tumors. Results Normalization of blood pressure and catecholamines urine levels was observed in 5 cases of pheochromocytoma during 6-19 months′ follow up after the treatment. In the 15 cases of aldosteronoma, aldosterone plasma levels reduced with potassium plasma levels increasing to the normal range within 5-7 days after the treatment. Aldosterone plasma levels increased with potassium plasma levels reduced again in 7 months after the treatment in one case, aldosterone plasma levels and potassium plasma levels returned to the normal range after the second treatment. Hypertension returned to normal in 13 cases of aldosteronoma, and one case maintained normal blood pressure (BP) only under the condition of taking lower dosage of spironolactone within 7-15 days after the treatment, and one month later, the blood pressure of the case become normal without taking any antihypertensive drugs. The other case maintained normal blood pressure in the need of taking lower dosage of antihypertensives after the treatment. CT scan showed total necrosis of tumors in 15 cases and majority necrosis in 5 case within 7-15 days after the treatment. Conclusion The therapy of percutaneous computed tomography-guided ethanol injection in adrenal benign functioning tumors shows satisfactory effects with the advantages of easy manipulation, safety, less injury and cost.
