Method and apparatus for monitoring drug effects on cardiac electrical signals using an implantable cardiac stimulation device

An implantable cardiac stimulation device, such as a pacemaker or Implantable Cardioverter Defibrillator, is configured to automatically monitor the effects of antiarrhythmic drugs on cardiac electrical signals within a patient to verify the efficacy of the drugs taken. In one example, an analysis of patient cardiac electrical signals is performed by comparing the cardiac electrical signals with values representative of the effects of different classes of antiarrhythmic drugs. If the implantable device determines that the prescribed antiarrhythmic drugs have not been effective, a warning signal is generated. The warning signal is conveyed directly to the patient via a bedside monitor and to the patient's physician via remote connection to an external programmer device so that both are notified of the drug efficacy problems. Additionally, the implantable device may be configured to automatically adjust pacing and defibrillation control parameters in an attempt to compensate for any lack of efficacy in the drugs. For example, the aggressiveness of overdrive pacing may be increased. Alternatively, a drug pump is controlled to adjust the dosage of antiarrhythmic drugs if an initial dosage is found to be ineffective.

Sterilizing application of cross-linking agent

A method for treating an eye includes applying, to an outer protective layer of an area of an eye, one or more initial doses of a cross-linking agent that acts as a photosensitizer. The method also includes delivering, from a light source, one or more initial doses of ultraviolet light to the area of the eye. The cross-linking agent increases absorption of the ultraviolet light by the area of the eye, and the absorption of the ultraviolet light sterilizes the area of the eye before the outer protective layer is penetrated. Additionally, the method includes penetrating the outer protective layer of the eye to provide access to an area below the outer protective layer. Moreover, the method includes applying a treatment to the eye via the access provided by cutting the outer protective layer. In some embodiments, the cross-linking agent is Riboflavin, and the treatment is LASIK surgery.

Synergy effect of cobra neurotoxin polypeptide on hyperalgesia and tolerance and alleviating pain of opioids

An opioid receptor agonist is a powerful effect analgesic medicine which is clinically and widely used, morphine is representative, and the medicine can effectively relieve pain of patients, particularly for pain of people after an operation and in the terminal cancer. However, opioids are easy to cause tolerance and hyperalgesia of patients, and the tolerance and the hyperalgesia can be easily formed within one week. Once the tolerance and the hyperalgesia are formed, dosage is continuously increased to continue to maintain the effect of alleviating pain, namely that organisms need a massivedose of medicines to achieve the effect of alleviating pain as the initial dose, but the higher dose can cause serious hyperalgesia, tolerance, constipation, addiction and respiratory depression. Cobra neurotoxin polypeptide can restrain the hyperalgesia and the tolerance of the opioids, and can also improve the treatment effects of opioids, and when the cobra neurotoxin polypeptide and the opioids are combined together for use, the opioids can alleviate pain at the lower dose and does not generate tolerance and hyperalgesia, so that the clinical technical problem that the opiods cannot be used for a long term can be solved.
