To overcome the present limitations of passive biochip, based on the basic principle of antigen-antibody reaction, we develop an antigen-antibody reaction model of solid-phase surface and design a novel active biochip system according to this model, which introduces the negative pressure and controlling devices to control the immunoreactions on the nitrocellulose (NC) membrane. From the computer simulation results, this is a rapid, stable, robust and practicable system, which can be used to increase the efficiency of immunoreactions and improve the reproducibility and accuracy of biochip analysis.

To characterize the clinical and molecular features of a patient with maturity-onset diabetes of the young 11(MODY11) and literature review. The patient was a 30-year-old female with hyperglycemia for 2 years. Failure to thrivea, primary amenorrhea, intellectual impairment, and severe hyperlipidemia were present at the same time. A novel mutations of the B lymphocyte kinase gene(BLK) c. 1025C>T(p.A342V) was found in the patient. Literature review revealed that there were more than ten mutation sites in BLK-MODY11. Some of them had hyperglycemia, over weight or systemic lupus erythematosus. To date, the clinical characteristics of the patient, such as growth retardation, primary amenorrhea, and intellectual impairment have not been reported in MODY11. Our clinical report further expands the clinical presentations and variabilities of MODY11.
