The Fourier transform infrared spectra of the key organs derived from Kidney (Shen)-yang deficiency syndrome mice.

Objective: To explore an approach to rapidly and accurately identify the compounds as biomarkers of Chinese medicine (CM) syndromes.

Method: The Fourier transform infrared (FT-IR) spectrometry was applied to investigate the characteristic components of a mice model of Kidney (Shen)-yang deficiency syndrome (KDS), and the remedial effect of a typical CM formula Shenqi Pill (). Thirty-six females and 18 males of Balb/c mice were randomly divided into KDS, Shenqi or control group.

Stabilizing the bactericidal activity of hydrogen peroxide: a brand new function of certain Chinese herbs.

Objective: To explore natural herbs to maintain the bactericidal activity of hydrogen peroxide (H).

Methods: Eighteen extracts of Chinese herbs were prepared complying with the standard protocol. Each of the solutions was then mixed with 1% H2O2.

[Detecting Down syndrome with a novel dual-color competitive quantitative fluorescent polymerase chain reaction method].

Objective: To develop a rapid method for the detection of Down syndrome (DS) using dual-color competitive quantitative fluorescent polymerase chain reaction (DCC-QF-PCR), and to assess its feasibility for the prenatal diagnosis of Down syndrome.

Methods: DNA was extracted from peripheral blood of 30 DS patients and 60 normal men, common primers for DSCR and USC2 genes and respective TaqMan probes were designed and synthesized. The results of DCC-QF-PCR were compared with those of QF-PCR which measured the ratio between DSCR and GAPDH.

[Effect of dihydroartemisinin on the expression of BCR/ABL fusion gene in leukemia K562 cells].

Objective: To investigate the effect of dihydroartemisinin (DHA) on the BCR/ABL fusion gene in leukemia K562 cell.

Methods: K562 cells were cultured in vitro. The rate of proliferation inhibition of cells treated with various concentrations of DHA were determined by using [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] (MTT) method.

[The application of CY7C09449 in interface between DSP and the PCI bus].

Objective. To introduce the usage of CY7C09449 in the interface between DSP and the PCI bus. Method.
