Objective To study the effect of aspirin on cell proliferation of human gastric cancer cell line SGC-7901 and the probab le mechanism involved. Methods Using MTT method, flow cytometr y (FCM),~~~3 H-TdR incorporation a nd electron microscopy, the effect of aspirin on the SGC-7901 of proliferation and related mechanism were studied. Results Results showed that th e growth of SGC -7901 was inhibited by aspirin. The inhibitory rates for growth of SGC-7901 we re positively correlated with the concentration and duration of aspirin in the m edia. ASA could inhibit DNA syntheses. Sub-G_1 pe ak was detected by FCM, and the rate of apoptosis was between 7.8% and (34.4)% . The cell ratios o f S and G_2/M increased, whereas the cell ratio of G_0/G_1 phase decreased (after) treatment and was in a dose-dependent manner. The SGC-7901 cell line exhibited some mor p hologic features of apoptosis, including cell shrinkage, nuclear condensation, D NA fragmentation, and formation of apoptotic bodies under electron microscopy. Conclusions Aspirin inhibited the growth of human gastric cancer ce ll line SGC-7901. The effects of aspirin on the phase of cell cycle and inducing apoptosis may be partially explained as the cytotoxic effects of aspirin.

Objective To explore the clinical efficacy of small-incision Dewar's operation for acute acromioclavicular dislocation.Methods Without exposing the a-c joint,the coracoid tip with tendon were transferred to the clavicle to reconstruct the coracoclavicular ligaments.And then the a-c joint was statically fixed and dynamically replaced.Results A 1-to 9-year follow-up(mean,4.9 years)was available in 52 patients.According to the Lazzcano Criteria,44 cases had excellent and 7 cases had good results,only one was failed because of bolt prematurity at 2 month after the operation.Roentgenogram,CT,and MRI showed that the surface of the acromioclavicular joint was smooth,no arthritic sign of cirrhosis,hyperplasia,or theca.The signal of the a-c joint was uniform.The Roentgenograms showed that,at the neutrality position,the distal end of the clavicle of the injured side was higher than that of the healthy side.The D/W of the healthy side was 0.432?0.101,which was significantly higher than that in the injured side(0.523?0.083,t=2.188,P=0.042).The difference between the neutrality and hold of the healthy side was 0.116?0.025,while that of the injured side was 0.087?0.016(t=1.114,P=0.280).The Roentgenograms of the raise position showed no impact in the a-c joint.Conclusions Small incision Dewar's operation is an effective,safe,and minimally invasive method for the treatment of acute acromioclavicular dislocation.

Objective Stem cell therapy has been extensively used in clinical practice. However ,the methods available are unable to non‐invasively detect the distribution of cells in vivo. This study was aimed to establish a novel molecular imaging probe for stem cell labeling ,which would monitor cells via fluorescence imaging. Methods 1‐iodododecane was used to modify polyethyleneimine (PEI) to form amphiphilic macromolecules. These macromolecules encapsulated the hydrophobic quantum dots by self‐assembly to form imaging probes. Results Strong fluorescence signals of the probe occurred at 630 nm ,and the probe could be effectively endocyted by mesenchyme stem cells. In vivo imaging showed that significant optic signals occurred in probe‐labeled mesenchyme stem cells compared with the control cells (blank group:1.47e8 [p/s/cm2/sr]/[μW/cm2 ];test group:2.78e8 [p/s/cm2/sr]/[μW/cm2 ]). Conclusion The nanoprobes have good optic imaging effects ,and can be used to la‐bel cells.

TFL1 homologs play important roles in maintaining vegetative growth and inflorescence meristem identity. The plants without the function of this gene usually are flowering earlier. Their normal inflorescence development is inhibited, the inflorescence meristem eventually acquired floral identity, which producing a terminal flower. Up to now, the TFL1 homologs have been isolated from 28 species of plants, including Arabidopsis, Snapdrogen and Tomato. The phylogenic tree of TFL1 proteins is almost accordance with the relative of those plants. The inflorescence identity gene TFL1 interacted with floral meristem identity genes LFY and AP1, so as to retard the transformation from inflorescence identity into floral identity. These meristem identity genes such as TFL1 and LFY can be applied in breeding of earl-flowering cultivars, there also have plenty of potentials in breeding fruit-free plantanus, popular or willows.
