Abstract:
Objective To find out the impact of SHI-1 cells on VOCs in the headspace, and to assess the feasibili-ty of VOCs analysis in leukemia patients or with other tumors in the differential diagnosis by determing VOCs in the headspace of acute mononuclear leukemia cells(SHI-1). Methods The air samples from the headspace of SHI-1, Human macrophages cells and medium control were collected by syringes, and then determined by means of solid phase microextraction-gas chromatography/mass spectrometry ( SPME-GC/MS ) in order to have a better under-standing of the concentration distributions and changes of VOCs in SHI-1 cells' headspace. Results Using Mann-Whitney U test, we found that eight kinds of VOCs were different among them. They were 2,4-dimethyl heptanes, 4-methyl octane, chloroform, benzene, 3,7-dimethyl dodecanese, hexanol, cyclohexanol, cetane. And alkane, benzene were significantly higher than the control group ( P<0.05 ) , alcohol decreased significantly ( P<0.05 ) . Conclusion SHI-1 cells have an impact on the concentration distributions of VOCs in their headspace. The most outstanding VOCs are alkanes, alcohol and benzene compared with the blank control group. They may be potential markers characteristic of leukemia cells.
