1.Research on functions and mechanisms of MicroRNA-203 on migration of human hypopharyngeal carcinoma cells
Journal of Regional Anatomy and Operative Surgery 2015;(3):241-244
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 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 explore the application of central venous catheter(CVT) in hemodialysis.Methods The clinical data of 2 206 cases of CVT patients were analyzed retrospectively,and the catheter puncture site,the catheter indwelling time,4 weeks of blood flow rate and the incidence of catheter related infections,and so on were observed.Results Internal jugular vein in 2 033 cases,the femoral vein in 173 cases.Internal jugular vein indwelling catheter time was (40.6 ±32.7) d,the femoral vein catheter indwelling time was (22.4 ± 16.3) d,and the difference was statistically significant (P< 0.05).Blood flow patency rate in four weeks was of 96.4% (1 959/2 033) indwelling catheter in internal jugular vein,which was significantly higher than that of the femoral vein in 83.2% (144/173),and the difference was statistically significant (P < 0.05).Femoral vein catheter related infection rate was 11.0% (19/173),significantly higher than that of internal jugular vein in 3.6% (73/2 033),the difference was statistically significant (P < 0.05).Conclusion Application of CVT for hemodialysis is convenient and reliable,with low infection rate,fewer complications,operation technology level is the key to success.

Objective To study the prognostic factors of gastrointestinal stromal tumors (GIST).Methods A total of 144 GIST patients treated at the First Affiliated Hospital of Guangxi Medical University between January 1996 and December 2011 were analyzed restrospectively.Kaplan-Meier,log-rank test and Cox regression model were used.Results The overall 5-year survival was 59.6%.Log-rank univariate survival analysis showed that the primary location,tumor size,metastasis,operational method,type of tumor cells,invasion of the surrounding organs and tissues,invasion of the smooth muscle,cellularity of the tumor,mitotic counts of the tumor cells,Ki-67 labeling index,P53 expression and targeting therapy were significant prognostic factors (P < 0.05).Cox regression model showed that tumor size,metastasis,operational method,surrounding organs and tissues invasion,cellularity of the tumor,mitotic counts of the tumor cells,P53 and targeting therapy were essential to improve the survival.Conclusions The study suggests that early diagnosis and comprehensive treatment consisting of operation and targeting therapy can significantly improve the survival of GIST.

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.
