20150162978 | Method and Apparatus for Increasing Capacity of Air Interface - The disclosure provides a method and an apparatus for increasing the capacity of an air interface. The method comprises the following steps that: after a traffic channel is established on a base station side, a base station transmitting a ⅛ rate frame to the air interface in a continuous transmission mode if not capturing a traffic channel frame prefix from a terminal, so as to ensure that the terminal can receive a forward frame of the base station; the base station only reducing the transmission of the ⅛ rate frame after capturing the prefix from the terminal; and the terminal keeping calling and does not release the call if continuous good frames are received during the demodulation of forward traffic frame from the base station. Through the disclosure, the interference between forward channels is reduced, and the capacity of the air interface is increased. | 06-11-2015 |

20130237596 | Uses of 15-benzylidene-14-deoxy-11,12-didehydroandrographolide Derivatives in the Preparation of Antineoplastic Drugs - The present invention relates to the preparation of anti-tumor drugs with andrographolide derivatives, which belongs to the field of pharmaceutical technology, and involves 15-benzylidene substituted derivatives of 14-deoxy-11,12-didehydro-andrographolide and their 3,19-ester derivatives. Proved by the experiments, these compounds significantly inhibited the colony formation and migration ability of various cancer cells, and also inhibited the migration ability of vascular endothelial cells in vitro. The compounds of this invention significantly inhibited the tumor growth, invasion, metastasis and angiogenesis on mouse xenograft models, and inhibited the experimental lung metastasis of B16-F10 malignant melanoma cells. Therefore, this class of compounds could be used as the active ingredients for the preparation of antineoplastic drugs, which are of efficiency and low-toxicity. Thereby it has potential to expand the selectable range of clinical drug and is of high significance to make full use of the plant resources of | 09-12-2013 |

20140187627 | USES OF C15-SUBSTITUTED ANDROGRAPHOLIDE DERIVATIVES IN THE PREPARATION OF ANTI-HEPATITIS B VIRUS MEDICAMENT - Disclosed is a use of C15-substituted andrographolide derivatives in preparation of anti-hepatitis B virus medicaments. In the present invention, the HepG2.2.15 cells are used to measure the amount of the hepatitis B virus surface antigen (HBsAg) secretion in the supernatant of the culture; the duck hepatitis B virus (DHBV) is used to infect the model and the DHBV-DNA level in serum is measured, and the pathological change in hepatic tissue is observed. A number of andrographolide derivative compounds are screened, compounds having a good anti-HBV effect are preferred, which has a structure represented by general formula 1 set forth herein. Due to high anti-HBV activity and low toxicity, as well as good protection against hepatic injury, the compounds can be used as the active ingredient for preparing anti-HBV medicaments, thereby providing a new pharmaceutical way for treatment of hepatitis, and broadening the range of clinical medicines. | 07-03-2014 |
