Enterovirus 71 (EV71) commonly occurs in children, causing hand, foot and mouth disease (HFMD) in about 29% of patients. Studies have suggested that patients develop meningitis and encephalopathy with a mortality rate of 4-26%. EV71 subgenotypes including B4, B5, C2, C4 and C5 have caused HFMD epidemics in Taiwan. In terms of therapeutical strategy,(More)
Intravenous immunoglobulin (IVIG) manufactured from human plasma contains IgG as the primary ingredient, and is used for indications such as immunodeficiency syndrome. Available IVIGs in Taiwan are either manufactured from Taiwanese or North American plasma. The effectiveness of the national immunization program of Taiwan can be evaluated by analyzing and(More)
The widely used Achyranthis Bidentatae Radix (Niu Xi) in Chinese medicine preparation is easily misused and confused with Cyathulae Radix (Chuan Niu Xi). Taiwan authority has ruled that Achyranthis Bidentatae Radix and Cyathulae Radix should be individually entered in the given preparations.

Hepatitis B virus (HBV) infection is a critical health issue. In hospitals, in vitro diagnostic devices (IVDs) are used to detect HBV infections. The Taiwan Food and Drug Administration has prepared a candidate hepatitis B surface antigen (HBsAg) proficiency panel as an analytical standard to evaluate the sensitivity of the postmarketing surveillance of HBV(More)
Owing to the rapid and mature development of emerging biotechnology in the fields of cell culture, cell preservation, and recombinant DNA technology, more and more cell or gene medicinal therapy products have been approved for marketing, to treat serious diseases which have been challenging to treat with current medical practice or medicine.
