Objective To know the efficacy of oral nursing by visible electric toothbrushes among patients with peroral endotracheal intuabtion. Methods Divided 108 trauma patients with peroral endo-tracheal intubation and clear consciousness into the research group and the control group randomly, there were 54 cases in each group. Routine oral nursing cares were used in the control group, while the visible electric toothbrushes was used in the research group. Compared the efficacy of oral nursing between the two groups. Results The incidence rate of mouth odor, plaque index and oral infection in the research group were better than those of in the control group. Conclusions Using visible electric toothbrushes for trau-ma patients with oral endotracheal tube is a kind of effective and feasibility method, which should be devel-oped in the clinical field.

To develop optimal shift systems for an improvement of work schedule satisfaction, health and work productivity, the effects of the direction of the rotational work shifting on the circadian rhythm and adaptation of physiological components and work mistakes were investigated in nursing students. Two groups of seven volunteers participated as experimental subjects, apd seven to twenty nursing students participated as a control group. The directions of rotation work shift were as follows CW(clockwise)-shift system rotation in the direction of day shift(3 days), evening shift(3 days), off duty(l day) and night shift(5 days), and CCW (counterclockwise) -shift system rotation in the reverse direction. Urinary Na, K, and Cl levels were measured with ion-selective electrodes. The levels of performance were measured by a questionnaire to determine the number of mistakes in 12 specific items during duty. The disturbance of Na the circadian rhythm was seen on day and night shifts, especially in the CCW-rotation shift system, and the magnitude of the daily variation was greatest in the CCW-rotation system. The daily rhythms of K and Cl shifted to the right on the evening shift, and the rhythms were reversed on the night shift, which suggests that they adapted to the altered shift work. However, the levels of Cl were higher in day and night shift workers, especially in CCW-shift system. In the ease of urine salts, it seems that the students in CW-shift system more easily adapted to the altered shift. The incidence of mistakes during work were more frequent on the CCW shift than in the CW shift. These data indicate that the direction of rotation effects the worker's health and work performance. These results indicate that the CCW rotation of shift work makes it more difficult for the workers to adapt to the shift on a physiological level, and has many more negative effects on the shift workers' health when compared with the CW rotation. Thus, a clockwise rotating shift system seems to be more desirable for the optimal health and performance of nurses.

Object To investigate the reason of the low germination and sprout rates by studying on inhibitory activities of the crude extracts of the seed of the dried root of Saposhnikovia divaricata (Turcz.) Schischk (DRSD) on Brassica, wheat and the seed of DRSD. Methods The ether extract and residue of the crude extract were prepared and treated by paper chromatography. The inhibitory activities of different fractions with different Rf value were determined. Effect of steeping the seed in warm water at 41 ℃ and 45 ℃ for different periods of time was also studied, respectively. Results There are intrinsic inhibitor in the seed of DRSD with strong activity. The portion of its ether extract with Rf 0.6 showed the strongest inhibitory activity for the germination of Brassica seed. The crude extract of the seed of DRSD also has the stronger inhibitory activity to the germination and growth of tender root of S. divaricata and has the same effect on aerial part of wheat sprouts. Steeping with warm water and solvent can remove most of the intrinsic inhibitor. Conclusion Intrinsic inhibitor in the seed of DRSD is the main factor that results in the low germination and sprouting slowly after seeding.

Objective:To culture neural stem cell (NSC) in vitro,observe its biological property and provide basis for further study on differentiation.Methods:NSC of rat fetus were isolated and cultured.Single-cell clone culture was used to confirm the character of self-renewing.Ability of multi-directional differentiation and specific antigen, nestin,were detected by immunocytochemistry (ICC).BrdU was used to show cell stage in division.Effect of combination of EGF,bFGF on proliferation of rat NSC were evaluated.Results:The cultured NSC showed multipotential of differentiation into neurons and glial cells,as well as the ability of self-renewing.Cells expressed nestin.The population of the NSC expanded quickly and the total number of the cell increased 2.45?10~4 folds after 15 times' passage.The property of NSC was stable after long culture and preservation.Combination of EGF and bFGF stimulated cell proliferation than used singly.Conclusion:The cultured NSC express nestin, have the ability of self-renewing and multi-directional differentiation.Combination of EGF and bFGF could promote the proliferation of rat NSC.

Objective:To study the effects of nimesulide on proliferation and apoptosis of human gastric carcinoma cells SGC-7901 in vitro,and provide an experimental basis for clinical application.Methods:Proliferation of human gastric carcinoma cells SGC-7901 was assessed by MTT,and apoptosis was detected by transmission electron microscope and flow cytometry.Results:Proliferation of SGC-7901 was inhibited significantly by nimesulide(range from 12.5 to 800?mol/L) in a dosage-dependant manner ( P

Objective:To investigate the effects of all-trans retinoic acid (ATRA) on prolifetation and differentiation in ovarian cancer cell line COC1 in vitro.Methods:Human ovarian cancer cell line COC1 was cultured in medium containing ATRA in different concentrations in vitro.Cell proliferation inhibition was tested by MTT assay.The cell cycle was analyzed by flow cytometry(FCM).Morphological changes of cell differentiation were observed by light and transmission electron microscopy,and the expression of Ki-67 in cancer cells were measured with SP immunohistochemistry.In addition,CA 125 expression in the culture medium was measured by ELISA.Results:ATRA of 10 -7 ～10 -5 mol/L inhibited COC1 cell proliferation significantly in a dose-dependent and time-dependent manner.With the increase of ATRA concentrations,the number of cells in G 0/G 1 phase were elevated,the number of cells in S phase were obviously decreased.COC1 cells after treated by ATRA showed striking morphological characteristics of differentiation.The expression of Ki-67 was decreased in COC1 after ATRA treatment.ATRA could also suppress the expression of CA125 tumor marker in COC1 cells.Conclusion:ATRA can both inhibit proliferation and induce differentiation of human ovarian cancer cell line COC1.These results may provide an effective and novel approach for clinical treatment of human ovarian cancer.

Objective To observe whether laminin(LN) is expressed in the developing kidney of mouse and the changes of the expression associated with maturation and polarity. Methods Eight fetal and fourteen postnatal kidneys were examined by immunohistochemistry(Strepavidin Peroxidase conjugated method,SP),using polyclonal rabbit anti-mouse antibody. Results The expression of laminin in the kidneys increased with the gestational weeks of fetus and maturity of the kidney.The expression of laminin was positive in monocell,multicell without space and multicell with space.In the developing kidney,the laminin is expressed in the ureteric bud,glomerular basement membrane(GBM),tubular basement membrane(TBM),renal capsular basement membrane and interstitium.The expression of TBM was prior to the expression of GBM.Conclusion The expression of laminin in the developing kidney of mouse has chronological and spatial sequence.The laminin determines the polarity of cell.Laminin might play a key role during nephrogenesis.
