Objective To investigate the effects of turmeric volatile oil extracted from curcuma on human lung adenocarcinoma A549 cell line. Methods The morphological changes of human lung adenocarcinoma A549 cells treated by different concentrations of turmeric volatile oil were observed by inverted microscopy, Giemsa staining, and Acridine orange staining. Results ① The inverted microscopy revealed that after treatment of A549 cells with different concentrations of turmeric volatile oil for 24-72 h or specified concentration of turmeric volatile oil for 1-7 d, the lung carcinoma cells were distributed sporadically, cells were scarce, and the majority of cells were in round or oval shapes, indicating that the cell proliferation was inhibited. These changes were associated with the concentration of turmeric volatile oil. ② Giemsa staining indicated that the apoptotic rates of A549 cells were 34% and 42% respectively after turmeric volatile oil treatment at the concentrations of 0.8 ?l/ml and 1.0 ?l/ml. There was significant difference in apoptotic rate between the treatment groups and the negative control group (13.5%, P

Objective To reconstruct tissue-engineered uterine patch similar to native endometrium and myotrium. Methods The purified rabbit uterine smooth muscle cells and stromal cells were mixed with liquid type Ⅰ collagen, and laid on mold respectively. Then the collagen-embedded cells were combined to create a cell complex, epithelial cells were inoculated on top of the complex, histological and immunohistochemical staining, and scanning electron microscopy were used to analyze the engineered uterine tissue. Results The engineered uterine tissues (EUTs) were reconstructed with isolated and cultured uterine smooth muscle cells, stromal cells and epithelial cells. After cultured for 14 days, histological and immunohistochemical analyses showed that the smooth muscle cells and stromal cells in the EUTs distributed evenly in the two layers and the majority of the cells, with elongated nuclei, stretched along the stretching direction. The morphology of EUTs resembled that of the native uterine tissue. In scanning electron microscopy, some epithelial cells protruded pinopodes. The surface of epithelial cells was covered abundantly with microvilli and some cells were ciliated. Conclusion Uterine smooth muscle cells and stromal cells were mixed with Liquid type Ⅰcollagen respectively, and epithelial cells were inoculated on top of the complex for generation of EUTs similar to the native uterine tissue.

Objective To evaluate the radiofrequency catheter ablation for type I atrial flutter through application of Holo catheter labelling with anatomic imaging localization to ablate the isthmus of IVC TA during complete double way block.Methods Eleven cases with type I atrial flutter undergone Holo catheter labelling technique and consecution with conduction time change of coronary venous sinus orifice withright atrial lower lateral wall pace excitation ,were performed with radiofrequency catheter ablation for the isthmus outcoming with complete double way conduction block. Results All together 11 cases with 4 of atrial flutter and 7 of sinus rhythm were undergone radiofrequency catheter ablation resulting with double way conduction block of the isthmus accompanied by prolongation of right atrial conduction time 56.0?2.3ms and 53.0?4.6ms respectively.The right atrial excitation consecution during coronary venous sinus orifice and right atrial lower lateral wall pace excitation appeared to be in clockwise and counter clockwise of single direction. No recurrence occurred during 3-34 months follow up with only one showing atrial fibrollation.Conclusions The application of Holo catheter labelling technique with anatomic imaging localization to achrieve the double way conduction block by radiofrequency catheter ablation of TVC TA isthmus, is a reliable method for treating atrial flutter.

In order to investigate the effects of verapamil on the proliferation of meningiomas cells in vitro and in vivo, the cultured meningiomas cells were cultured with verapamil at different concentrations for 24 h and the inhibitory effects of verapamil on cell proliferation were observed by MTT method. The meningiomas model was established by implanting the newly removed tumor fragments into the nude mice subcutaneously. The nude mice with tumors were divided into two groups: verapamil-treated group and control group. Tumor volumes were measured and after 12 weeks the tumors were taken out and examined histologically. The expression of proliferating cell nuclear antigen (PCNA) in the tumors was detected by using immunohistochemistry. It was found that verapamil could inhibit the growth of cultured meningiomas cells in a concentration-dependant manner. The inhibitory effect could be observed in the concentration of 1 micromol/L verapamil and the most obvious effects appeared in the concentration of 100 micromol/L. Tumor volume in the verapamiltreated group was obviously smaller than that in the control group (211.40+/-5.50 vs 163.94+/-3.62, P<0.01) and the expression of PCNA was also lower (1.52+/-0.24 vs 2.86+/-0.53, P<0.05). Tumor inhibition rate was about 22.45%. It was suggested that verapamil could inhibit the proliferation and growth of meningiomas cells in vitro and in vivo.

Objective To construct an eukaryotic expression vector encoding an shRNA targeting CA916798. Methods According to the CA916798 cDNA sequence in GenBank, 2 pairs of oligo nucleotides were designed and synthesized. After primer annealing, they were inserted into plasmid pGenSil-l to construct the shRNA eukaryotic expression vector. The recombinant plasmid were transformed into DH5?, and the positive strain were identified by enzyme digestion and sequence analysis. The recombinant vector were transfected into A549/CDDP cells with Lipofectamine 2000. Drug sensitivity and proliferation of the transfected cells were measured by MTT test.
