Abstract: A use of bio-transformed bear bile powder in preparation of anti-inflammatory drugs is disclosed. The present invention carries out a comparative research on the anti-inflammatory drug activity of bio-transformed bear bile powder and natural bear bile powder. A research is made on the effect of the bio-transformed bear bile powder and natural bear bile powder on carrageenan-induced rat inflammation models, and a research is made on the effect of the bio-transformed bear bile powder on LPS-induced lung inflammation in mice. Experimental results show that the bio-transformed bear bile powder administration group obviously reduces plantar swelling of carrageenan-induced inflammation model in rats, and the effect thereof is not lower than that of the natural bear bile powder. Both the bio-transformed bear bile powder and the natural bear bile powder can significantly reduce levels of the inflammatory factors IL-6 and TNF-? in the lung and the serum.

Abstract: Disclosed a MEMS assembly and a manufacturing method thereof. The manufacturing method comprises: forming a groove on a sensor chip; forming a bonding pad on a circuit chip; bonding the sensor chip and the circuit chip together to form a bonding assembly; performing a first dicing process at a first position of the sensor chip to penetrate through the sensor chip to the groove; performing a second dicing process at a second position of the sensor chip to penetrate through the sensor chip and the circuit chip, for obtaining an individual MEMS assembly by singulating the bonding assembly, wherein location of the groove corresponds to a position of the bonding pad, and an opening is formed in the sensor chip to expose the bonding pad when the second dicing process is performed. The method uses two dicing process respectively achieving different depths to expose the bonding pad of the sensor chip and singulate the MEMS assembly, respectively, to improve yield and reliability.

Abstract: The presently disclosed devices, methods, and systems involve direct and intuitive visualization using gaze-control in robotic laparoscopy. For example, when the system detects a new visual interest, the robot may guide the scope to approach or move toward the target view. In order to achieve the disclosed control, a system coordinate transformation is developed. The disclosed devices, methods, and systems may translates gaze positions on image (in pixels) to relative rotation angles and/or translation distances of the laparoscope. In most cases, this relationship, which may be built, in part, on the parameters of the laparoscope and the inserted laparoscope length in the patient's body, may allow the robot to directly follow the surgeon's gaze position on the monitor. The disclosed devices, methods, and systems may help to reduce cognitive and physical burdens on a laparoscopic surgeon.
