Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

Abstract: The present invention relates to a series of dicarboxylic acid ester derivatives of ginsenosides such as succinate and glutarate derivatives of 20-O-?-D-glucopyranosyl-protopanaxadiol (compound K, abbreviated as CK), preparation thereof and pharmaceutical uses thereof. The dicarboxylic acid ester derivatives of ginsenosides of the present invention can be used to form pharmaceutical acceptable salts thereof having a high water solubility or can be directly dissolved in an aqueous solution of metal salt, and retain the pharmaceutical activities of ginsenosides such as tumor growth inhibition and cancer preventive cytotoxicity. The dicarboxylic acid ester derivatives of ginsenosides of the present invention are thus suitable for use in the manufactures of various pharmaceutically and cosmetically acceptable dosage forms of preparations, such as peripheral, oral, and topical dosage forms.

Abstract: An adjustable rod bending device includes a support table, a pivot base mounted on the support table, a pivot bracket pivotally mounted on the pivot base, and multiple juxtaposed rollers mounted in the pivot bracket to pivot therewith and each having an upper end adjustably mounted in the pivot bracket and a lower end formed with an arcuate pressing surface. The arcuate pressing surface of each of the rollers can be moved to press a corrective spinal rod supported by two support posts, thereby accurately bending the corrective spinal rod.
