When high-intensity ultrasound acts on a liquid medi um, the cavitation can produce a high temperature above 5 000 K and a high press ure about 50 MPa at local sites, accompanied by a forceful impact wave and a jet with 400 km/h. The mechanical action can generate mechanical movement with high frequency whose acceleration can be 1 500 times of gravitational acceleration.

功率超声作用于液态媒质时，空化作用会在局部点产生 5 0 0 0K以上的高温和 50MPa左右的高压，并伴有强烈的冲击波和时速达 40 0km的射流，机械作用会产生高频变化的机械运动，加速度可达重力加速度的 1 50 0倍，这些独特的效应令其在化工领域中的应用越来越广泛。

Results:Whith the time and doses of ART incubation extended, ART significantly inhibited the proliferation of SGC-7901 cells and the inhibited effect shows dose-and -time-dependent. Obvious changes of apoptotic morphology were observed by invert microscope, fluorescence microscope, scanning electron microscope and transmission electron microscope, they showed that cells had marked nuclear condensation or the fragmentation of chromation as well as apoptotic , mitochondrial edema and vesicle , with the time of incubation extended , the proliferation rate become slow and the volume became small and transformed. FCM assay indicated that most of the cells were arrested in Go/Gi and the apoptotic peak appeared. During the prolong of incubation time, the apoptosis rate was increased. At the same time, the number of S and G2/M phase cells were decreased. The result of TUNEL indicant that there are apoptosis and necrosis.

Cell proliferation and viability were assayed 48h after transfection, and MDA-7 demonstrated selective inhibition of tumor cell growth, inhibitory rates of A549, Hela and HepG2 cell lines were 25%, 20% and 19%, respectively, but had no significant effect on human fetal kidney derived 293 cell line. Hela cell was screened by G418 for 2 weeks after pcDNA3-MDA-7 and monolayer colony was counted, its monolayer colony formation was 30% of cells transfected with pcDNA3. 0 vector. CMV-driven MDA-7 adenovirus vector was constructed. 293 showed no significant apoptosis during adenovirus packaging and the unpurified adenovirus titer was about 1×10〓pfu/ml. Cos 7, A549, Hela, HepG2 and Hep3B cell was infected with Ad-GFP at different MOI.
