The informed consent is the principle of medical ethics with which all the doctors in hospital should consistently comply in their medical therapy. Particularly in operation therapy, it is so important for doctors to insist on this medical ethics principle which embodies the specific principle for patients' dectisions for themselves. This accords with the general norm of medical ethics that patients are respected by the hospital. This principle is the morality requirement for operation therapy, and also one of the important measures for effectively reducing and avoiding medical disputes.

Spontaneous retinal venous pulsations(SVPs) appears in 90％ of normal persons.It is seen as a rhythmic subtle narrow and expansion of one or more retinal veins on the optic disc.Many researches have demonstrated that SVPs could be applied to the intracranial pressure(ICP) monitoring as well as diagnoses and fellow up of glaucoma.But there is no corresponding domestic research in this field up to now.Although the physiological mechanism of the venous pulsations has been the point of much debate,its potential clinical value attract our attention.The present paper reviewed the progress in current understanding of the mechanism behind the SVPs,the examination method and application of SVPs in clinical study.

Objective To assess the role of various factors in the sterilization effect of ozone in water and provide the basic data for the correct use of ozone generator. Methods E.coli 8099 was employed as the indicative bacteria. The effect of killing E.coli 8099 by ozone in water was detected under various conditions,such as temperature,pH value,flux. Results The inactivated rates of indicative bacteria were 99.99%～100% by ozone in five minutes under the basic condition of 20 ℃,pH=7.0 and ozone flow of 1 L/min. The bactericidal effect was relatively better at low temperature and low pH value,the high flow of ozone led low sterilization effect of ozone. Conclusion High temperature,higher pH value,higher flow is not conducive for ozone to be dissolved in water,thereby will affect the bactericidal effects of ozone.
