The fabrication and experimental test results were presented for a micro-electro-mechanical systems (MEMS)-based gas chromatography column. Compared with conventional column, this micro-gas chromatography column is suitable for on-line analysis and monitoring because of the small size, rapid analysis and other characteristics. These 0.5, 1 and 3 m GC columns were fabricated using a deep reactive-ion etching (DRIE) and were coated the stationary phase via a dynamic coating procedure. These GC columns perfectly separated the mixture of benzene, toluene and o-xylene in less than 200 s, where, the 3.0 m of the GC column achieved) a high resolution of 14.3 between toluene and o-xylene and yielded approximately 6160 plates. Moreover, the effect of separation performance for different column length were examined and compared. These GC columns are suitable for the application of a variety of disciplines, including environmental analysis, methane gas probes and homeland security.

Objective: To observe the effect of hypoxia on changes of proliferation ability of cultured human periodontal ligament fibroblasts (HPLFS) in vitro. Methods: HPLFS were randomly divided into two groups (experimental group and control group) by different oxygen concentrations. The oxygen concentration of control group was 21%. The oxygen concentrations of experiment group were 10%, 5% and 2%. The proliferation ability of HPLFS was detected by MTT colorimetric assay. The cell ultrastructure was observed by transmission electron microscope (TEM). Results: MTT assay results showed that compared with the control group, at the 12 h and 24 h, cell proliferation was enhanced with the hypoxia degree. At 24 h, cell proliferation showed significant differences. At 48 h and 72 h, proliferation of the cultured HPLFS in severe hypoxia group reduced significantly. Observed by TEM, at 24 h, not only the number of mitochondria, rough endoplasmic reticulum but also cell process increased in the cultured HPLFS in severe hypoxia group. At 72 h, the number of lysosome increased and the cell structure degenerated. Conclusion: Long-time severe hypoxia may lower the repair and remodeling abilities of periodontium, which might be one of the important etiological factors of periodontal disease under condition of high altitude.
