OBJECTIVETo explore the inhibitory effect of cinnamaldehyde on invasion capacities of human breast cancer cell line MDA-MB-435S and its relation with regulating the expression of miR-27a.

METHODSThe effect of cinnamaldehyde on invasive capacities of MDA-MB-435S was measured by Transwell matrigel invasion assay. The effect of miR-27a expression on invasive capabilities of MDA-MB-435S, the intervention of cinnamaldehyde in the miR-27a expression, and its relation with its effect on invasive capabilities were defected with liposome 2000 transinfection miRNA27a mimics/inhibitors, real time-polymerase chain reaction (Real-time PCR), and Transwell chamber model.

RESULTSCompared with the control group, the number of cells passing through the transwell chamber was more significantly reduced after treated by cinnamaldehyde for 12 h (P < 0.05). The miR-27a expression was 962.07 times and 40% of that of the control group after transinfected by miR-27a mimics and miR-27a inhibitors. After transinfected by miR-27a inhibitors, the number of cells passing through the transwell chamber was more significantly reduced (P < 0.05). The miR-27a expression of MDA-MB-435S was down-regulated by 12-h treatment of cinnamaldehyde (2(-deltaCt) = 0.56, 0.18, 0.18, respectively). The number of miR-27a mimics transinfection pretreated MDA-MB-435S cells passing through the transwell chamber increased more obviously than the number of un-pretreated MDA-MB-435S cells in the control group (P < 0.05).

CONCLUSIONSCinnamaldehyde could inhibit invasive capabilities of human breast cancer cell line MDA-MB-435S. The over-expression of miR-27a played an important role in the invasive capability of MDA-MB-435S. The inhibition of cinnamaldehyde on invasive capabilities of MDA-MB-435S cells was correlated with down-regulating the expression of miR-27a.

Enzyme - linked immunosorbent assay was performed for detecting the concentration of IL- 1? and IL-8.Results The percentage of mCD14 positive AM in experimental group [(54.772 ?17 .341)%] was higher than that in control group [(14.023? 10. 713)% ](t= -7.739 P

Objective To study the attitude and knowledge of pulmonary tuberculosis among clinical nurses,so as to provide reference evidence for launching targeted tuberculosis special training.Methods Convenience sampling was adopted to investigate 375 nurses in Grade A hospital with tuberculosis questionnaire.Results The average score of related knowledge of pulmonary tuberculosis among clinical nurses was ( 18.71 ±3.45) with a medium level,and the dimensions score of protection measure,medicine control was lower and respectively was (3.88 ± 1.25 ) and (4.15 ± 1.11 ).The average score of attitude among nurses was (40.08 ±6.01) with a medium level.The tuberculosis nursing experience,attitude and titles were the important influencing factors of knowledge score ( P＜ 0.05 ),and the attitude of pulmonary tuberculosis was positively correlated with knowledge and training(r =0.187,0.122,respectively ;P ＜0.05 ).Conclusions The knowledge of pulmonary tuberculosis among nurses is incomprehensive,ss it is important to strengthen the training on the knowledge of tuberculosis and improve nurses' attitude for the tuberculosis patients,and fully play their role in the prevention and treatment of the pulmonary tuberculosis.

To assay the influence of dendritic cells(DCs)on the function of anti-infective immunity to Penicillium marneffei.DCs were generated from peripheral blood mononuclear cells(PBMC)and pulsed with Penicillium marneffei yeasts.DCs morphology was observed by the inverted microscope and cell surface markers of DCs were analyzed by flow cytometry.The concentrations of IL-12p70 were detected by ELISA. Mixed lymphocyte reaction was performed to assay the proliferation of T cells.The mRNA of CCR7 and CXCR4 were detected by the Real-time PCR quantifications.The acquired DCs exhibited irregular appearance and numerous long dendrites under light microscope.DCs and Penicillium marneffei yeasts were co-cultured for 24 h,numerous yeasts were observed inside the cells;an enhanced expression of the cell sur-face markers CD86、CD83、HLA-DR and CD40 were demonstrated;the expression of CCR7 and CXCR4 mRNA were also increased;the improved proliferation of T cells were observed in the mixed lymphocyte reaction.Yeasts-pulsed DCs secreted more IL-12p70 than that of non-pulsed,but less than that of LPS-pulsed DCs.DCs can engulf the Penicillium marneffei yeasts.When pulsed with Penicillium marneffei yeasts,DCs improved their expression of the co-stimulatory molecules and chemokine receptor CCR7、CXCR4,enhanced their capacity to process antigen.DCs play an important role in host defense against Penicillium marneffei infection.But the low level of the IL-12p70 production may lead to deficiency in the cell-mediated immunity against Penicillium marneffei.

OBJECTIVETo explore the effects and mechanisms of multi-glycoside of Tripterygium wilfordii (GTW) on improving glomerular inflammatory lesion in rats with diabetic nephropathy (DN).

METHODDN model was induced by unilateral nephrectomy and intraperitoneal injection of STZ (35 mg x kg(-1)) twice. The rats were randomly divided into 3 groups, the sham-operated group (Sham group, n = 5), the vehicle-given group (Vehicle group, n = 5 ) and GTW-treated group (GTW group, n = 5). After the model was successfully established, the rats in GTW group were daily oral administrated with GTW suspension (50 mg x kg(-1) x d(-1)), meanwhile, the rats in Vehicle group were daily oral administrated with distilled water (2 mL) for 8 weeks. From the beginning of the administration, all rats were killed 8 weeks later. Blood and renal tissues were collected,and then UAlb, renal function, glomerular morphology characteristics and glomerular macrophages (ED1 + cells) infiltration, as well as the protein expressions of inflammatory cytokines including tumor necrosis factor(TNF)-α and interleukin(IL)-lβ, and the key molecules in p38MAPK signaling pathway including p38 mitogenactivated protein kinase (MAPK), phosphorylated p38 (p-p38MAPK) and transforming growth factor(TGF)-β1 were investigated respectively.

RESULTGTW not only ameliorated the general state of health and body weight,but also attenuated UAlb, glomerulosclerosis, the infiltration of glomerular ED1 + cells and the protein expressions of TNF-α, IL-1β, p-p38MAPK and TGF-β1 in the kidney in DN model rats.

CONCLUSIONBy means of DN model rats, we demonstrated that GTW has the protective effect on renal inflammatory damage in vivo via inhibiting inflammatory cells infiltration and inflammatory cytokines expression. Furthermore, GTW could improve renal inflammatory lesion through down-regulating the expressions of the key signaling molecules in p38MAPK pathway such as p-p38MAPK and TGF-β1 ,and inhibiting the activation of p38MAPK signaling in the kidney.

OBJECTIVETo explore the clinical effects of anterior decompression and fusion with a nano-hydroxyapatite/ polyamide 66 (n-HA/PA66) cage in treating lower cervical fracture and dislocation.

METHODSFrom January 2008 to December 2010, the clinical data of 42 patients with lower cervical fracture and dislocation were retrospectively analyzed. There were 29 males and 13 females aged from 20 to 65 years old. The mean age was 46.8 years. Five cases got injuried in C3, 14 cases in C4, 12 cases in C5, 7 cases in C6 and 4 cases in C7. According to Frankel grade, 4 cases were classified in grade A, 11 cases in grade B, 13 cases in grade C, 9 cases in grade D and 5 cases in grade F. Twenty-eight cases were treated with anterior corpectomy and fusion and 14 cases with anterior discectomy and fusion. Frankel grade was used to do neurologic assessment and visual analogue scale (VAS) was used to evaluate the improvement of clinical symptoms. Segmental height and sagittal lordosis were measured by radiographs and cage location. Cage appearance and fusion status were assessed by 3D-CT images.

RESULTSAll patients were followed up for 3 to 5.2 years with an average of 4.1 years. Frankel grade had obviously improved than preoperative (Z = -4.845, P < 0.001). There were 2, 3, 11, 8, 11 cases classified in grade A, grade B, grade C, grade D and grade E respectively. At the third day after operation and latest follow-up,VAS was (2.6 +/- 1.8),(1.3 +/- 1.0) scores respectively. Both had improved than preoperative (P < 0.05). Up to the latest follow-up, there was only one patient (2.4%) with slight cage translocation (less than 2 mm), however, no cage prolapsed, or collapse, or breakage were found. Both segmental height and lordosis improved significantly after surgery (P < 0.001). And there was not significant difference in both parameters between each postoperative time points (P > 0.05). The mean distance of cage subsidence was 1.5 mm and the rate of cage subsidence (> 3 mm) was 4.8%.

CONCLUSIONThe n-HA/PA66 cage can not only restore and maintain the fusion segmental height and radian, but also promote the osseous fusion and profit the radiographic assessment after operation. Thus, it was an ideal material for prop graft.
