AIEA adopts novel selection operation according to the stimulation level of each antibody. A memory base for good antibodies is devised simultaneously to raise the convergent rapidity of the algorithm and adaptive adjusting strategy of antibody population is used for preventing the loss of the population adversity. The experiments show AIEA has better convergence performance than standard genetic algorithm and is capable of maintaining the adversity of the population and solving function optimization problems in an efficient and reliable way.展开更多

Although there are many hypothyroid patients who use levothyroxine as a treatment, high level of thyroid stimulating hormone is found in a limited number of levothyroxine overdose cases worldwide.Patient concern: A 34-year-old male patient taking 4.5 mg levothyroxine for suicide. Diagnosis: Overdose of levothyroxine. Interventions: The patient was admitted to the intensive care unit for follow-up treatment. Cardiac rithym and vital parameters of patient were closely monitored. Outcomes: The patient discharged without any life-threatening complications. Lessons: Patient with initial high thyroid stimulating hormone levels may not be in hyperthyroidism crisis by levothyroxine poisoning.展开更多
