ABSTRACT
Internet hospitals played a huge role in meeting patients’ medical needs during the COVID-19 pandemic. As a new service model, it also brings new challenges to medical ethics. This paper analyzed the three key elements of behavior: actors, behavior process and action result, and found that apart from ethical challenges such as medical security, data security and privacy protection, different types of Internet hospitals show diversity due to different actors involved. The first type of Internet hospital represented the conflict of interest of doctors brought by the integration of offline and online working modes. The second type showed the challenge of fairness in medical treatment brought by the demand of personalized service provided by medical staff in public medical institutions. The third type manifested the medical security challenges brought by doctors with varying technical levels in an open platform environment. Combined with the current ethical governance of science and technology and the digital transformation of society, this paper put forward some countermeasures and suggestion, such as further clarifying the boundaries of rights and responsibilities of relevant subjects of Internet platform, formulating the code of conduct requirements for medical staff in Internet hospitals, and supervising doctors’ medical practice in Internet hospitals.
ABSTRACT
Objective:To assess impact of radiation from nuclear power on the surrounding environment, a dose assessment model was constructed and relevant dose coefficients were determined through refined animal models.Methods:Zebrafish is one of the most important aquatic model animals in the radiation hazard assessment of nuclear power liquid effluent. A geometric model of zebrafish containing internal bones and visceral organ was established for dose estimation. The internal and external dose coefficients (DC) of the zebrafish model were calculated by Monte Carlo method with seven nuclides as the source term, 3H, 40K, 58Co, 60Co, 110Ag, 134Cs, 137Cs, which are common in nuclear liquid effluents and environmental monitoring. Results:The level of nuclide gamma energy determines dose coefficients for external radiation. The dose coefficients of most nuclides in internal organs was higher than that in whole body, and the internal organ dose of 58Co was 165% higher than that in whole body. The internal radiation dose coefficients of the model established in this study was relatively high, and the internal radiation dose coefficients caused by 60Co was 2.6 times of existing ellipsoid model, which suggested that the different internal materials and the choice of different particle types would affect the energy deposition. Conclusions:Refining of model animals is important. Accurate assessment of the organs dose coefficients of model animals is helpful to assess the radiation effects on non-human species.
ABSTRACT
Objective To summarize the author' s clinical experiences in the diagnosis and treatment of urachal carcinoma.Methods Thirteen cases with urachal carcinoma from 1990-2011 at Beijing Friendship Hospital affiliated to Capital Medical University were retrospectively reviewed and analyzed.Results The most common complaint was hematuria;B ultrasonic or CT scan demonstrated a parenchyma or vesica between the bladder dome and abdominal wall.Nine patients underwent extensive pattical excision of the bladder,3 paitents underwent radical resection,and 4 patients received comprihensive chemotherapy.The five-year survival rate was 30.7％.Conclusion Extensive partial excision of the bladder is recommended for urachal carcinoma.
ABSTRACT
@#Objective To observe the effect of Acupoint Thread Embedding on the motor function of children with cerebral palsy. Methods90 children with cerebral palsy were divided into 2 groups by the visiting time and gender: the observation group accepted AcupointThread Embedding and comprehensive rehabilitation while the control group accepted comprehensive rehabilitation only. They were assessedwith Gross Motor Function Measure before and 3 months after treatment. Results The incidence of efficiency was 95% in the observationgroup and 80% in the control group (<i>P</i><0.01). The score of Gross Motor Function Measure was higher in the observation group thanin the control group (<i>P</i><0.01). Conclusion Acupoint Thread Embedding can promote the motor functional recovery of children with cerebralpalsy.
