Objective To determine the roles and underlying molecular mechanism of MicroRNA-203 on the migration of human hypo-pharyngeal carcinoma cells. Methods The potential MicroRNA-203 target genes were searched by bioinformatic miRNA target prediction tools and KEGG database,and a large number of candidates was identified. The MEKK1 was selected for further investigation. This gene is known to play a role in tumor metastasis. The MicroRNA-203’s binding sites in MEKK1’s mRNA 3’UTR were analyzed by luciferase report-er assays. Nextly,the protein expression of MEKK1 in Fadu-Lv-MicroRNA-203 cells was determined by Western blot assay. The regulation of MEKK1’s mRNA expression by MicroRNA-203 was analyzed by qRT-PCR. Transwell cell migration assays were performed to confirm the im-pact of MicroRNA-203 on hypopharyngeal carcinoma metastasis. Results The expression level of endogenous MicroRNA-203 was negatively correlated with the mRNA and protein expression levels of MEKK1 in hypopharyngeal carcinoma cells. Transwell migration assay results showed that MicroRNA-203 overexpression inhibited hypopharyngeal carcinoma cell migration ability. Furtherly,MEKK1 can promote hypo-pharyngeal carcinoma cell migration ability. Conclusion MEKK1 is a direct target of MicroRNA-203. MicroRNA-203 plays a role in hypo-pharyngeal carcinoma cell migration ability through MEKK1.

Stroke is one of the major diseases that threaten human health, early diagnosis and treatment are very important for stroke. Carotid intima-media thickness (CIMT) is measured noninvasively to diagnosis stroke, and it is a independent predictor for stroke because its thickening can timely predict the incidence and development of stroke. As an important predictor of cardiovascular disease, more and more attention is played on CIMT. In this review, we will make a summary on the important role of CIMT in stroke and the mechanisms of carotid intima-media thickening in stroke as well as the potential use of traditional Chinese medicine in treating carotid intima-media thickening.

Rabbit blood samples were exposed to constant magnetic field within a range of intensity from 0.05 T to 0.35 T for 10 to 50 minutes, the propersities of hemorheology were measured by ektacytometry. The following results were obtained: The blood viscosity was lowed;The RBCs deformability was not changed obviously except for 10 minutes of exposure when the RBC＇s deformability was strongly decreased; The orientation index was increased; The results indicate that the magnetic field increases the RBC surface charge and results in the decrease of blood viscosity.

Objective To explore the effect of situational clinical probation fourth-step method in Nursing Managementteaching in clinic.Methods We introduced innovative teaching method in clinicsituational clinical probation fourth-step method in Nursing Management.Firstly,it took students to learn the construction of the management structure in clinic (observation),then interview management persons (interview),and playing roles in management activities (role-play),at last interactive discussion (seminar).Results Through the SCP fourth-step learning,the nursing students' learning ability was strengthened,the students' ability to innovate and the learning interest in nursing management were inspired.Conclusions Application of situational clinical probation fourth-step method in Nursing Managementteaching in clinic shows better effect,which should be widely applied in clinic practice.

Objective To investigate the relationship between cancer-related fatigue (CRF) and quality of life (QOL) of the colorectal cancer patients.Methods In this study,patients diagnosed definitely as colorectal cancer were enrolled from November 2010 to January 2011 in this hospital.Piper Fatigue Scale was used to assess the CRF and QLQ-C30 was used to assess the QOL.Results 74 patients were enrolled in this study,and among them 28 patients had CRF(37.84％).Patients with CRF was significantly worse in QOL than patients without CRF.Physical function,role function,emotional function,social function and the general health subscale had a negative correlation with CRF,while pain,fatigue and loss of appetite had a positive correlation with it.Conclusions CRF had an impact on QOL,and this study will provide some reference information when the nurses take measures to intervene CRF and improve QOL of the colorectal cancer patients.

Objective To evaluate the efficacy of entecavir treatment on hepatitis B patients with acute-on-chronic liver failure. Methods Eighty-four hepatitis B patients with acute-on-chronic liver failure were treated with entecavir 0.5 mg daily and Other routine drugs. Another 99 hepatitis B patients with acute-on-chronic liver failure were treated with only routine drugs as control. The survival, liver functions, hepatitis B virus (HBV) DNA level, prothrombin time (PT) were observed. The survival rates of patients with early, middle or late stage of liver failure were analyzed. The comparison of rates were done using chi-square test. The numeration data were compared by t test. The survival rates were compared using Kaplan-Meier method. Results Among patients with early stage of acute-on-chronic liver failure, the survival rate in treatment group was 63.3% (31/49), which was significantly higher than that in control group (39.7%, 23/58) (χ2=5.923, P=0.015). Among patients with middle stage of acute-on-chronic liver failure, the surviral rate in treatment group was 63.0% (17/27), which was significantly higher than that in control group (35.1%, 13/37) (χ2=4.854, P=0.028). Among patients with late stage of acute-on-chronic liver failure, four out of eight cases survived in treatment group, while one out of four cases survived in control group. In patients with serum total hilirubin (TBil) level > 342 μmol/L, the survival rate was 56.0% in treatment group, which was significantly higher than that in control group (26.8%) (χ2=9.351,P=0.002). At week 4 of the treatment, the HBV DNA reduction in treatment group was 3. 95 lg copy/mL, which was higher than that in control group (1.78 lg copy/mL) (t=5.847, P=0.001). Conclusions Entecavir treatment could improve the survival rate of hepatitis B patients with early or middle stage of acute-on-chronic liver failure. And the further study with larger population is needed in patients with late stage of liver failure. In addition, entecavir therapy could also improve the survival rate of patients with TBil >342 μmol/L.

Objective To investigate the impact of nutritional risk of preoperative patients with different parts of colorectal cancer. Methods 385 cases of surgical patients diagnosed with colorectal cancer were selected in the retrospective study in April 2008 to March 2009, Gastrointestinal Surgery Center of West China Hospital in Sichuan University. Patients were divided into the right colon cancer group, the left colon cancer group, the rectal cancer group, using internationally recognized NRS- 2002 Scale and serum nutrition indicators to assess their preoperative nutrition. Results NRS-2002 score in the right colon cancer group showed higher than the left colon and rectal cancer group, but no statistical difference between the latter two rates; serum concentrations of HGB, TP, ALB, A/G were lower in the right colon cancer group than the other two groups, but the concentrations of ALT, AST, Ca2+, PO43-showed no statistical difference among three groups. Conclusions The proximal colon (right colon cancer) were more susceptible to the risk of preoperative malnutrition, the patients with different parts of colorectal cancer should be given to the corresponding preoperative nutritional assessment and nutritional support.

Objective:To identify the HLA-A0201 restricted CTL epitopes derived from hepatitis B virus X protein predicted by computer program and general principles in vitro.Methods:HBx gene sequences of Hepatitis B virus genotypes B/C and serotypes adw/adr,with the highest frequencies in Chinese,were computed and analyzed by screening service offered by Internet combined with peptide supermotif,extended motif and quantitative motif prediction.Four most ideal nine-peptides(HBx1,HBx2,HBx3,and HBx4)were selected as candidate peptides.Using flow cytometry,the fluorescence index of both control and experimental groups were detected and the 4 nine-peptides were evaluated with T2 binding assay and DC50 assay.Results:The nine-peptides VLCLRPVGA(HBx1),CLFKDWEEL(HBx2),VLHKRTLGL(HBx3)and HLSLRGLPV(HBx4)were selected as candidate targets.Among the 4 candidate peptides,HBx2 showed higher HLA-A0201 affinity and HBx2,HBx4 showed better stability.Conclusion:Our study indicates that CLFKDWEEL might be a potential HLA-A0201 restricted CTL epitope from hepatitis B virus X protein;further study is needed for verification of its immunity in vivo.
