Publication number: 20130172283Abstract: The invention belongs to the pharmaceutical field, and particularly relates to a lyophilized formulation of pectin-adriamycin conjugate and a preparation method thereof. In order to solve insolubility problem of the pectin-adriamycin conjugate (hereinafter referred to as PAC), improve bioavailability and facilitate preparation, the inventor prepared the PAC into a nanosuspension. However, as long-term stability of the nanosuspension is poor, the inventor proposed to prepare the nanosuspension into a lyophilized formulation, that is, an insoluble pectin-adriamycin conjugate is prepared into a suspension or nanosuspension, and a lyophilized support agent is added to the suspension for lyophilization treatment to prepare the lyophilized formulation. Lyophilized products prepared from the nanosuspension are characterized by enhanced stability of nano-particle size and enhanced stability of drug loading rate, which provides a new solution for clinical application of the PAC.Type: ApplicationFiled: April 22, 2011Publication date: July 4, 2013Applicant: CHONGQING LUMMY PHARMACEUTICAL CO., LTD.Inventors: Xiaohai Tang, Yu Qiu

Patent number: 8410774Abstract: An electromagnetic motion sensor includes a base, an electromagnetic induction layer, a block, and an emitting coil. The electromagnetic induction layer with a plurality of induction coils is arranged on the bottom of the base. The block is movably connected to the base by a plurality of elastic members. The emitting coil is fixed to a center of the bottom of the block facing the induction layer. A circuit inside the block provides current to the emitting coil. The block moves with the jerk of the motion sensor when the motion sensor is jerked, causing the elastic members to be distorted. The relative movement between the block and the magnetic induction layer causes more than one of the induction coils generate and output voltage signals according to the change of magnetic flux through the plurality of induction coils caused by the moving of the emitting coil.Type: GrantFiled: September 1, 2010Date of Patent: April 2, 2013Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Yu-Qiu Yang, Song-Ling Yang

Publication number: 20120244193Abstract: The invention relates to a passive solid tumor-targeted anticancer prodrug and a preparation method thereof, belonging to the field of antitumor drugs. The preparation method includes the following steps: reacting low molecular weight pectin with Mw of 5,000-45,000 with doxorubicin to obtain a pectin-doxorubicin conjugate with Mw of 100,000-1,000,000, preparing the conjugate into a suspension, and treating the suspension in an ultra-high pressure nano homogenizer to obtain the passive solid tumor-targeted anticancer prodrug with particle size of 100 nm-200 nm and melting point of 220-245°, wherein the pectin and doxorubicin are linked by an amide bond, and the pectin is linked by an ester bond formed by condensing carboxyl groups and hydroxyl groups of pectin molecules. Cell inhibition rate of the anticancer prodrug for humanized lung cancer cells NCI-H446 and A549 is equivalent to that of doxorubicin hydrochloride.Type: ApplicationFiled: May 19, 2010Publication date: September 27, 2012Applicant: CHONGQING LUMMY PHARMACEUTICAL CO., LTD.Inventors: Xiaohai Tang, Yu Qiu, Xin Song

Patent number: 7267808Abstract: The present invention is to produce an aluminum nitride powder which is turned into a sintered body at a temperature of not more than 1600° C., thereby obtaining a sintered aluminum nitride in which the density and thermal conductivity are high and which can be properly used as a substrate material. Using a vapor phase reaction apparatus shown in FIG. 1, ammonia gas was fed from a reactor 2 heated at from 300 to 500° C. and maintained at that temperature by a heating section 1 via a feeding tube 4 while being regulated by a flow regulator 3. At the same time, while being regulated by the flow regulator 5, nitrogen gas containing an organic aluminum compound is fed via a feeding tube 6 to obtain an aluminum nitride powder. The aluminum nitride powder is subjected to a heat treatment at from 1100 to 1500° C. in a reducing gas atmosphere and/or an inert gas atmosphere to obtain an aggregate aluminum nitride powder.Type: GrantFiled: July 6, 2005Date of Patent: September 11, 2007Assignees: Mitsui Chemicals, Inc., Advanced Industrial Science and TechnologyInventors: Masato Yamazaki, Kenshi Mitsuishi, Isao Harada, Masao Tanaka, Kohichi Haruta, Koji Watari, Jin-yu Qiu, Yuji Hotta, Kimiyasu Sato
