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.

Objective　To investigate the expression of glial fibrillary acidic protein (GFAP) gene and its significance in the process of glioma cell differentiation induced by nordihydroguaiaretic acid (NDGA). Methods　Immunohistochemistry (IHC) and in situ hybridization were used to detect the expression changes of GFAP protein and GFAP mRNA qualitatively and quantitatively. Results　The expression levels of GFAP protein and GFAP mRNA in NDGA treatment group were significantly increased compared with the control group (P<0.01). Conclusion　NDGA could induce GFAP gene in malignant glioma cells and the up-regulation of this gene expression might be one of the mechanisms by which NDGA induces glioma differentiation.

Objective: This study aims to analyze the outpatient prescriptions in primary rural health institutions in western China to reveal the feature and disadvantages of utilization of Chinese patent medicines in rural areas.Methods: A total of 14336 prescriptions were selected from 132 health institutions in rural areas of 7 provinces in western China in 2011.The utilization of Chinese patent medicines is described and compared to the health institutions in different levels and different provinces/autonomous regions.Results: The prescriptions of Chinese patent medicines accounted for 62.47% of the total prescriptions in rural health facilities.The proportion of county, township and village medical institutions was 49.76%, 56.96% and 71.51% respectively.86.84% of the Chinese patent medicines prescriptions were prescribed by physicians without traditional Chinese medicine background, while only 13.16% of them were traditional Chinese medicine physicians.The number of varieties of Chinese patent medicines in a single prescription in county, township and village health institutions were 1.38, 1.91 and 2.54, respectively and the average drug costs of every prescription in these health institutions were 52.20 yuan, 21.89 yuan and 19.37 yuan, respectively.Conclusions: There are differences in the utilization of Chinese patent medicines in outpatient prescriptions of rural health institutions in western China.The hospitals in higher medical level use more Chinese patent medicines.The drug cost of the prescription of county health institutions is higher than that of township and village hospitals.This study suggests that health policy should be adjusted based on the specific needs and characteristics of rural health institutions at a different level and should be implemented in the management of prescription in quality control.

Objective The objective of this paper is to statistically analyze what influence can the utilization of Traditional Chinese Medicine (TCM) have on healthcare expenses of inpatients, and to investigate whether TCM has an advantage of reducing healthcare expenses among certain diseases.Method: Inpatient medical records from 13 public general hospitals in Ningxia Hui autonomous region were collected to set up a database.A multiple linear regression models was established and used to analyze the impact of using TCM on hospitalization expenses.Results: The findings have shown that inpatients who apply TCM have significantly higher hospitalization expenses, with an estimated average of ?8 276.24, while those who do not apply TCM in their treatment spend ?7 254.59 on average (P=0.000).When the proportion of TCM expense higher than 10% of total drug expense, inpatients who apply the TCM have lower hospitalization expenses.In addition, hospitalization expenses decrease with the increase of TCM proportion.Among the diseases of the ear and mastoid disease, diseases of the circulatory system, and certain conditions originating in the perinatal period, inpatients who apply TCM have significant lower hospitalization expense (P=0.000).Hospitalization expense of inpatients who do not apply TCM is twice as much as that of those who apply TCM in the treatment of among diseases of the circulatory system, which has the largest TCM proportion.Conclusion: Only when applying TCM as main therapy can provide price advantage of TCM in the circulatory system caused by chronic diseases, and other advantages of treatment.

Objective To analyse the pregnancy rate after treatment of tubal pregnancy with the systemic methotrexate (MTX) injection Methods From March 1985 to August 1999, 129 women with confirmed unruptured tubal pregnancy,and desiring to conceive were selected Among them 60 women were successfully treated with systemic MTX, and 69 with unilateral salpingectomy All cases were followed up for 1～15 years Results The rates of subsequent intrauterine pregnancies (IUP) in the MTX group was 73% (44 cases) and of recurrent extrauterine pregnancies (EP) was 8% (5 cases) Among 69 patients treated by salpingectomy, the rates of IUP and EP was 70% (48 cases) and 4% (3 cases) respectively The differences between the two groups were not statistically significant Conclusions The effect of conservative management with MTX was similar to those of salpingectomy The rate of subsequent pregnancy did not increased

Objective To investigate whether damaged human amniotic epithelial cells(HAEC)could be repaired on the matrix of formulated fibrin clot in vitro and the effects of epidermal growth factor(EGF),basic fibroblast growth factor(bFGF)and transforming growth factor ?_1(TGF-?_1)on the proliferation of HAEC. Methods Ring drill was used to drill the HAEC layer on culture sheets to make quantified models of damaged HAEC, on which the lacks were then covered with fibrin clot. Subsequently, EGF (EGF group), bFGF(bFGF group) and TGF-?_1 (TGF-?_1 group) of different concentration were added into the sheets respectively. After the predesigned culturing time, the growing and transiting conditions of HAEC were observed under inverted microscope after Giemsa stain. Also, the proliferating conditions of HAEC were detected by using 5-bromodeoxyuridine(BrdU). Results In all groups, HAEC could transit toward damaged area on fibrin clot and grow there. Higher transiting speed and larger cell numbers were observed in the EGF and bFGF groups followed by the control group, while the TGF-?_1 group showed the relatively poorer results. Proliferating rates of HAEC were 17.8%, 28.0%, 35.3%, 51.6%, 34.1%, 34.2% and 26.0% respectively by EGF of different cultured concentration (1.0ng/ml, 5.0ng/ml, 10.0ng/ml, 20.0ng/ml, 40.0ng/ml, 80.0ng/ml and 160.0ng/ml). Proliferating rates of HAEC were 18.0%, 35.7%, 43.0%, 52.7%, 67.4%, 43.6% and 30.5% respectively by bFGF of different cultured concentration (1.0ng/ml, 5.0ng/ml, 10.0ng/ml, 20.0 ng/ml, 40.0 ng/ml, 80.0 ng/ml and 160.0ng/ml). Compared with the control group, EGF groups (EGF concentration ranging from 10ng/ml to 80ng/ml) and bFGF groups (bFGF concentration ranging from 5ng/ml to 80ng/ml ) showed better proliferating effects of HAEC(P
