The accurate and timely detection of biochemical coagulation indicators is pivotal in pulmonary and critical care medicine. Despite their reliability, traditional laboratories often lag in terms of rapid diagnosis. Point-of-care testing (POCT) has emerged as a promising alternative, which is awaiting rigorous validation. We assessed 226 samples from patients at the First Affiliated Hospital of Guangzhou Medical University using a Beckman Coulter AU5821 and a PUSHKANG POCT Biochemistry Analyzer MS100. Furthermore, 350 samples were evaluated with a Stago coagulation analyzer STAR MAX and a PUSHKANG POCT Coagulation Analyzer MC100. Metrics included thirteen biochemical indexes, such as albumin, and five coagulation indices, such as prothrombin time. Comparisons were drawn against the PUSHKANG POCT analyzer. Bland-Altman plots (MS100: 0.8206‒0.9995; MC100: 0.8318‒0.9911) evinced significant consistency between methodologies. Spearman correlation pinpointed a potent linear association between conventional devices and the PUSHKANG POCT analyzer, further underscored by a robust correlation coefficient (MS100: 0.713‒0.949; MC100: 0.593‒0.950). The PUSHKANG POCT was validated as a dependable tool for serum and whole blood biochemical and coagulation diagnostics. This emphasizes its prospective clinical efficacy, offering clinicians a swift diagnostic tool and heralding a new era of enhanced patient care outcomes.

Objective This study focused on the preparation of air plasma-activated water and its application in the field of disinfection.By developing single-layer and double-layer dielectric barrier discharge(DBD)devices,we aimed to prepare plasma-activated liquid with high-efficiency disinfection ability.Methods We constructed single-layer and double-layer DBD devices using air as the working gas to generate activated water.The plasma temperature variation,discharge process and emission spectrum were captured and analyzed by a thermal imager,a time-resolved enhanced camera and a high-resolution spectrometer to evaluate the efficient energy conversion and particle excitation capabilities of the device.In addition,disinfection experiments were conducted on typical microorganisms such as Bacillus subtilis,Escherichia coli and Staphylococcus aureus to verify the disinfection effect of the activation solution.Results We adjusted the plasma treatment time for accurate disinfection of typical microorganisms such as Bacillus subtilis,Escherichia coli,and Staphylococcus aureus.Compared with a single-layer DBD device,the double-layer DBD device could produce higher concentrations of reactive species,significantly improving the disinfection effect of the activated liquid.Conclusion By using the air plasma activated water technology,an activated solution with highly efficient disinfection capability was successfully prepared.This study not only improves the disinfection efficiency,but also has potential environmental friendliness and economy,which provides a scientific basis and technical support for the application of plasma technology in the field of disinfection.

Breast milk is the optimal natural food for newborns. However， some newborns cannot receive maternal breast milk due to reasons such as mother-infant separation or insufficient lactation. The establishment of human milk banks （HMB） can effectively address these issues， thereby increasing the breastfeeding rate among hospitalized newborns and improving their quality of survival. However， HMB in China is still in the development and improvement stage. Its implementation involves a series of ethical issues， such as informed consent， privacy protection， economic incentives， quality and safety， and fair resource distribution， which hinder HMB’s widespread promotion. Therefore， discussing the ethical dilemmas faced by the widespread establishment of HMB in China’s hospitals and analyzing coping strategies are crucial for improving the breastfeeding rate of newborns. This paper deeply analyzed and sorted out the ethical issues and challenges currently faced by HMB in China， and proposed corresponding strategies， including “ensuring informed consent and voluntary participation of both donors and recipients，” “protecting the privacy of donors and recipients，” “establishing an ethics-based moral incentive and social support system，” “strictly controlling quality and safety issues”， and “developing fair and rational policies，” aiming to provide a reference solution for addressing ethical concerns in the establishment and operation of HMB.

The red doctors spirit is a special cultural form formed by the Chinese Communist Party in the long-term revolutionary struggle practice, and it has important practical significance and value of the times in the new era. Medicine is a subject integrating natural science and humanities. The element of "emotion" is the embodiment of traditional Chinese medical culture. It plays a role in cultivating doctors’ spirit and solving practical problems in current medical activities. By digging the four aspects of the "emotion" element in red doctors spirit of political loyalty to the party, the moral sentiment of saving the dying and healing the wounded, the rational decision-making under the transformation of medical situation, the response and processing ability of bad public opinion, and integrating it into the humanistic education of medical students. This paper explored the effective ways and promotion models of the element of "emotion" education in the growth of medical talents, so as to promote the cultivation of medical talents’ moral cultivation and ethical decision-making ability, enhance the professionalism and humanistic cultivation of medical students, and cultivate a group of medical talents with political firmness and reasonable consideration for the country.

Coronavirus disease 2019 (COVID-19) has continued to spread globally since late 2019, representing a formidable challenge to the world's healthcare systems, wreaking havoc, and spreading rapidly through human contact. With fever, fatigue, and a persistent dry cough being the hallmark symptoms, this disease threatened to destabilize the delicate balance of our global community. Rapid and accurate diagnosis of COVID-19 is a prerequisite for understanding the number of confirmed cases in the world or a region, and an important factor in epidemic assessment and the development of control measures. It also plays a crucial role in ensuring that patients receive the appropriate medical treatment, leading to optimal patient care. Reverse transcription-polymerase chain reaction (RT-PCR) technology is currently the most mature method for detecting viral nucleic acids, but it has many drawbacks. Meanwhile, a variety of COVID-19 detection methods, including molecular biological diagnostic, immunodiagnostic, imaging, and artificial intelligence methods have been developed and applied in clinical practice to meet diverse scenarios and needs. These methods can help clinicians diagnose and treat COVID-19 patients. This review describes the variety of such methods used in China, providing an important reference in the field of the clinical diagnosis of COVID-19.

In the emergency response to public health emergencies, a series of ethical issues will be faced. One of the core issues is that the ethical conflict between personal freedom of medical staff and common good has not been effectively resolved, and the moral responsibility boundaries of medical staff have not been clearly defined. The personal freedom rights of medical staff are constrained in the emergency response to public health emergencies due to the prior moral requirements and regulations for them that emphasizes the priority of safeguarding public interests. Therefore, it is important to consider elements such as voluntariness, proportionality, priority, and fairness when balancing the tension between personal freedom of medical staff and common good. It is recommended to establish a rating system that endangers the life safety of medical staff, list the ethical list of "legitimate reasons" by the health administrative department, and improve the reward system of "moral and welfare consistency" to solve the ethical conflict between personal freedom of medical staff and common good, so as to better achieve common good.

In order to explore the ethical review experience of organ donation and transplantation after the death of citizens, and provide reference value for medical institutions to carry out corresponding ethical review. By using descriptive research, purpose sampling method and the principle of data saturation, 10 members and secretaries of ethics committee on clinical application of organ transplantation technology were finally selected as respondents for semi-structured interviews. The Colaizzi 7-step analysis method was adopted to analyze, summarize and refine the theme. The results showed that the ethical review experience of organ donation and transplantation after the death of citizens included four themes: the responsibilities of ethics committee, the key points of ethics review, the form of ethics review conference and its advantages and disadvantages, and the construction of the ethics committee of organ transplantation. Therefore, there are defects in the ethical review of organ donation and transplantation in medical institutions at present. These can be remedied by enriching elements of the ethical review following the four principles of medical ethics, refining the laws related to organ donation after citizens’ death, constructing a reasonable and efficient pattern of ethical review conference, and establishing a robust and appropriate operation mode of organ transplantation ethics committee.
