The result suggests that teachers should build the students' positive self-efficacy to improve their nurse-patient communication, ability.

The effect of tea saponins (TS) on rumen fermentation and methane emission was examined using an in vitro gas production technique named Reading Pressure Technique. Three levels of TS addition (0, 0.2, 0.4 mg/ml) were evaluated in the faunated and defaunated rumen fluid. Compared to the control, TS addition decreased the 24 h gas production in the faunated rumen fluid, but had a minor effect on gas yield in the defaunated rumen fluid. The TS significantly reduced methane production in vitro. In the faunated rumen fluid, 0.2 or 0.4 mg/ml TS decreased the 24 h methane emission by 12.7% or 14.0%, respectively. Rumen fluid pH value was affected neither by TS addition nor by defaunation. The TS addition had only minor effects on volatile fatty acids, but the yield and pattern of volatile fatty acids were greatly affected by defaunation. While the molar proportion of acetate was not affected by defaunation, the propionate was significantly increased and the butyrate significantly decreased. Ammonia-N concentration and microbial protein yield were influenced by TS inclusion and defaunation. Inclusion of 0.4 mg/ml TS increased the microbial protein mass by 18.4% and 13.8% and decreased the ammonia-N concentration by 8.3% and 19.6% in the faunated and defaunated rumen fluid, respectively. Protozoa counts were significantly reduced by TS inclusion. The current study demonstrated the beneficial effect of TS on methane production and rumen fermentation, and indicated that this may be due to the effect of the associated depression on protozoa counts.

OBJECTIVETo study the effect and mechanism of action of norcantharidin on proliferation and invasion of GBC-SD cells.

METHODSGBC-SD cells of human gallbladder carcinoma were cultured by cell culture technique. The tetrazolium-based colorimetric assay was used to evaluate cell growth. The Matrigel experiment and the crossing-river test were used to examine the invasiveness of GBC-SD cells. Expression of MMP(2), TIMP(2), PCNA and Ki-67 proteins of GBC-SD cells was determined by streptavidin-biotin complex method.

RESULTSNorcantharidin inhibited the growth and proliferation of GBC-SD cells in a dose and time dependent manner, with an IC(50) value of 56.18 micro g/ml at 48 h. The Matrigel experiment showed that norcantharidin began to inhibit the in vitro invasion of GBC-SD cells at the concentration of 5 micro g/ml. At 40 micro g/ml, the invasive action of GBC-SD cells was inhibited completely and their crossing-river time was prolonged significantly. After treatment with norcantharidin, the expression of PCNA, Ki-67, MMP(2) was significantly decreased. With the increase in TIMP(2) expression, the MMP(2) to TIMP(2) ratio was decreased significantly (P < 0.05).

CONCLUSIONNorcantharidin inhibits the in vitro proliferation and growth of human gallbladder carcinoma cells at relatively low concentrations by inhibiting PCNA and Ki-67 expression. Its anti-invasive activity may be the results of decrease in MMP(2) to TIMP(2) ratio and reduced cell motility.

There was significant difference except for the incidence of cGVHD.Conclusion Allogeneic hematopoietic cell transplantation may be appropriate for older patients with malignant hematological diseases.

Abstract?AlM:To investigate the influence of lOL refractive index ( Rl ) on measurement of straylight following cataract surgery.?METHODS:ln this case-control study, 77 eyes of 77 age-related cataract patients who underwent cataract phacoemulsification with posterior chamber aspherical arylic lOL implantation surgery in the Eye Hospital of China Medical University from Aug 2013 to Mar 2014, with a best corrected visual acuity ( BCVA) of 0. 5 or better, were classified into 3 groups randomly using 3 types of lOL: Tecnis ZCB00 Group ( Rl = 1. 47, 22 eyes of 22 subjects); Hoya PY60AD Group ( Rl=1. 52, 24 eyes of 24 subjects);Alcon SN60WF or lQ Group ( Rl=1. 55, 31 eyes of 31 subjects ) . BCVA, pupil size, astigmatism, axial length, intraocular straylight were measured respectively.? RESULTS: Age, axial length, BCVA, pupil size, astigmatism of the three groups were not significant difference (P>0. 05). The straylight of Tecnis, Hoya, lQ group were 1.04±0. 15, 1. 19±0. 14, 1. 14±0. 18. Straylight levels had significant differences among three groups ( F=5. 352, P = 0. 007 < 0. 05 ). There was no significant correlation between BCVA and straylight value (r=-0. 133,P=0. 124>0. 05).?CONCLUSlON:Patients chosen the higher Rl lOL may have a higher straylight level after the surgery.

Objective To analyze the clinical value of minimal residual disease(MRD) of acute myeloblastic leukemia(AML) with AML 1-ETO by using the real-time quantitative reverse transcriptase polymerase chain reaction(RQ-RT-PCR).Methods From Jan.2001 to Jan.2007,the MRD of 32 AML1-ETO-positive AML patients were analyzed by using PQ-RT-PCR.The detection of the AML1-ETO was taken after the induced chemotherapy every 1.5-2.0 months during the consolidation therapy.The survival of different stages in children with AML was analyzed by SPSS 10.0 software and calculated by using Kaplan-Meier analysis.Results Thirty-two patients received the induced chemotherapy and 29 patients with complete remission morphologically,3 patients had no complete remission morphologically and then gave up.Patients with molecular remission were associated with a high probability of survival(P=0.001 8).Patients with high transcript levels at diagnosis had no difference in event free survival with patients with low transcript levels.The quality of molecular response after induction,6 months in the chemotherapy as well as consolidation period,has significant impact on the event free survival(P=0.023,0.000 1,0.004 9).Conclusion The current study demonstrate that quantitative evaluation of AML1-ETO transcript levels is important and may be helpful for therapeutic decisions in future.

The purpose of this study was to explore the significance of abnormal karyotype in diagnosis and prognosis estimation of myelodysplastic syndrome (MDS). Chromosome analysis were performed in 306 cases of MDS using the short-term culture of bone marrow cell and G-banding technique, and in partial cases FISH technique was used for this analysis. 93 out of 306 cases were followed up. The results showed that 144 cases (47.1%) had clonal chromosome aberrations. The most common chromosomal aberrations included +8, translocation, complex or high complex karyotype, -7/7q-, 20q-/-20, trisomy 1 or partial trisomy 1, +11/+11q-, -9/9q-, +9/9q+, -Y, dup(1q), +21. The rate of abnormal karyotype in refractory anemia with erythroblasts (RAEB) and refractory anemia with erythroblasts-transformation (RAEBT) were much higher than in refractory anemia (RA) and refractory anemia with sideroblasts (RAS) (P < 0.05). The rate of abnormal karyotype among those cases with mutagen contact history were higher than those in cases without mutagen contact history. The patients with abnormal karyotype had a mean survival time much shorter than patients with normal karyotype (P < 0.005) and had a higher risk transforming into acute leukemia (P < 0.05). The worst outcome was observed in those patients with a complex or high complex karyotype, -7/7q- and trisomy 11. In conclusion, MDS is highly heterogeneous disorders and karyotype analysis is helpful for its diagnosis, treatment selection and prognosis estimation.
