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 evaluate the inflammatory response and the expressions of peroxisome proliferator-activated receptor(PPAR)isoforms(PPARα,PPARβ/δ,and PPARγ)in the brain(cortex,striatum,cerebellum)of spontaneously hypertensive rats(SHR).Methods Brain tissues(cortex,striatum,and cerebellum)were dissected from SHR and age-matched control Wistar-Kyoto rats.Myeloperoxidase(MPO)activity was measured in brain tissues as an index of neutrophil accumulation and the carbonyl protein content was analyzed by spectrophotometry to evaluate the protein oxidation.RT-PCR and Western blotting were performed to examine the expressions of inflammatory mediators(IL-1β,TNFα,ICAM-1,and iNOS)and nuclear factor PPARs(PPARα,PPARβ/δ,and PPARγ),respectively.Results(1)Systolic blood pressure of SHR was significantly higher than that of Wistar-Kyoto rats,(205.4±9.4)mm Hg versus(130.4±7.9)mm Hg(t=14.96,P<0.01).(2)MPO activity of cortex,striatum,and cerebellum were markedly higher in SHR than in Wistar-Kyoto rats.Carbonyl protein levels of cortex,striatum,and cerebellum in Wistar-Kyoto rats and SHR were(3.27±0.43)nmol/mg versus(11.87±1.11)nmol/mg,(4.02±1.04)nmol/mg versus(14.06±1.36)nmol/mg,(5.94±0.71)nmol/mg versus(14.95±1.82)nmol/mg,indicating significantly higher levels of protein oxidation in SHR than Wistar-Kyoto rats(t=17.70,14.36,11.30,P<0.05).Consistently,the expression of pro-inflammatory mediators(IL-1β,TNFα,ICAM-1,and iNOS)was upregulated when compared with Wistar-Kyoto rats.The difference between SHR and control Wistar-Kyoto rats was statistically significant except the mRNA expression of IL-1β in striatum,cerebellum and TNFα in cerebellum of SHR.All the above experimental data indicated the occurrence of inflammatory status in the brain tissue of hypertension.(3)mRNA and protein levels of brain PPAR isoforms(PPARα,PPARβ/δ,and PPARγ)of SHR increased significantly when compared with Wistar-Kyoto rats.Specifically.protein levels of PPARα in cortex.striatum,and cerebellum of SHR increased by 644.78%,791.95%,and 42.85%;PPARβ/δ increased by 106.72%,94.12%,and 161.44%;PPARγ was up-regulated by 2700.16%,790.81%,and 875.00%compared with that of Wistar-Kyoto rats,respectively.Conclusions The brain(cortex,striatum,and cerebellum)from SHR shows marked inflammatory status and increased expression of all PPAR isoforms.Increases in PPARs expression may play a compensatory role in the inflammatory response of the brain in SHR.

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.
