Objective:To understand the status and identify the determinants of self-treatment of rural floating population in Beijing. Methods: The data were derived from the Fourth National Health Service Investigation of China, part of which was about rural floating population in Beijing. According to Andersen health services utilization model, Binary Logistic Regression model was used to analyze the influencing fac-tors. Results:In the study, 51. 7% of the research objects were inclined to self-treatment when they ever felt uncomfortable or sick in Beijing. The Binary Logistic Regression model suggested that, some factors from predisposing, enabling and need, were statistically significant determinants of utilization of self-treat-ment. Conclusion:There exists a certain percentage of self-treatment behavior for rural floating population in Beijing, and we should take some measures to promote the efficacy and safety of self-treatment.

The hepatic portal system is a unique circulatory system that connects two systems of capillary beds ; one in the wall of the small intestine and spleen and the second in the sinusoidal area of the liver.Therefore,alterations in vasoreactivity (vasodilation and vasoconstriction) play a critical role in the pathophysiology of portal hypertension (PHT).The RhoA/ ROCK pathway exerts an important role in the Ca2+-independent mechanism in vascular smooth muscle (VSM).This mechanism not only modulates the constriction of intrahepatic small vessels and hepatic stellate cells (HSCs) but also effects the hyperdynamic circulation due to vascular hyporesponsiveness.Understanding the detailed mechanism and role of the RhoA/ROCK signal pathway in portal hypertension could be of great utility in providing a new target for portal hypertension therapy.

Objective To investigate the levels of hypersensitive C-reactive protein(hs-CRP)and serum lipid in patients with acute cerebral infarction.Methods A total of 300 patients with acute cerebral infarction and 300 healthy subjects (normal controls)were included in this study.The levels of hypersensitive C -reactive protein and serum lipid were measured and analyzed via statistics soft.Results The levels of hs-CRP,total cholesterol, triglyceride,low density lipoprotein and high density lipoprotein in the research group were (25.9 ±5.2)mmol/L, (7.5 ±2.3)mmol/L,(2.8 ±0.21)mmol/L,(0.8 ±0.1)mmol/L and (3.3 ±0.2)mmol/L respectively;The levels of hs-CRP,total cholesterol,triglyceride,low density lipoprotein and high density lipoprotein in the control group were (6.3 ±1.2)mmol/L,(4.2 ±0.2)mmol/L,(1.5 ±0.2)mmol/L,(2.2 ±1.5)mmol/L and(2.5 ±0.5)mmol/Lrespectively.There was a significant statistically difference between the two groups(t =5.9,5.1,4.8,4.6 and 4.5,all P <0.05).Multivariate Logistic regression analysis showed that total cholesterol,triglyceride,low density lipoprotein and high density lipoprotein hs-CRP were independent risk factors for the acute cerebral infarction (beta respectively 0.53,0.68,0.69,1.20,0.69;S.E were 0.23,0.16,0.28,0.24,0.25,OR values were 5.6,4.8,6.2,7.8,9.2;95%CI were 0.69 -36.8,0.57 -35.7,0.58 -38.5,0.68 -44.2,0.21 -48.2,all P <0.01).Conclusion The abnormal metabolism of serum lipid and C -reactive protein were independent risk factors in patients with acute cere-bral infarction,which should be positively treated about this.

Objective To prepare RGD conjugated paclitaxel and curcumin loaded liposome and evaluate their properties and effect on the treatment of ovarian carcinoma in vitro and in vivo . Method The liposomes were prepared by thin film hydration method. The particle size,Zeta potential and entrapment efficiency were evaluated. The efficiency of cellular uptake on A 2780 cells in vitrowas evaluated. Flowcytometry were used to observe the apoptosis morphous.A 2780 cells werexenografted in athymic mice to establish the animal model, which were used to evaluate the effect of anti-cancer. Results The particle diameter of the RGDLP-PTX/Cu was (94.8±11.2) nm with the Zeta potential of (-3±2.45) mV. The entrapment efficiency of PTX and Gen were 81.8%and 84.6%respectively. The result demonstrated that RGDLP uptaken by A 2780 were 3.6 times higher than that of LP. The apoptosis assay、the inhibition of the inhibition of tumor in vivoconfirmed strong inhibitory effect ofRGDLP-PTX/Cu. Conclusion RGDLP-PTX/Cu were easy to prepare and it is a potential delivery system for the treatment of ovarian carcinoma.

Objective: To study the clinical effect of nursing after laparoscopic myomectomy after nursing intervention. Methods: Retrospective analysis of our hospital from 2009 May to 2012 October in our department, laparoscopic myomectomy in the treatment of 148 cases of uterine fibroids patients clinical data, were randomly divided into 2 groups, 74 cases in each group, the control group routine nursing care to patients, nursing intervention on the patients with study group, The quality of life of patients with depression and anxiety scores were compared between the two groups before and after the rate and nursing of exhaust and ambulation time, hospitalization time, complications. Results: Research group of exhaust, ambulation, time of hospitalization, the incidence of complications compared with the control group, showed significant difference; the study group before operation and nursing of patients with anxiety and depression and quality of life scores compared with the control group, there was no significant difference, nursing intervention, there were significant differences. Conclusion: Laparoscopic myomectomy nursing intervention, can promote the rehabilitation, and improve the living condition, patients with significant effect, should be popularized.

MicroRNAs ( miRNAs) are a kinds of small non-coding RNA that regulate the expression of gene at the posttran-scriptional level and play important roles in a variety of physiological and pathological processes such as proliferation , differentiation and apoptosis.Recently, it has been reported that miRNAs expression abnormalities are closely associated with the initiation and devel -opment of glioma .Moreover , the expression levels of some miRNA are specifically involved in the molecular pathogenesis of glioma , revealing their great potential as a class of novel biomarkers for cancers and therapeutic targets .In this review , we summarizes the lat-est researches on miRNA and glioma .
