Objective:To investigate whether the increased plasma fibrinogen level is an independent predictor of cardiogenic embolism in patients with nonvalvular atrial fibrillation (NVAF).Methods:Ninety-eight patients with NVAF hospitalized for cardiac causes were evaluated,and 24 of them had a history of ischemic stroke.The relationship between fasting plasma fibrinogen level and ischemic stroke were analyzed.Results:After adjusting traditional cardiovascular risk factors.the patients with NVAF who had the history of ischemic stroke were significantly older than those without(mean [SD] age 73.6 [8.4]vs.69.1[10.3] years,P=0.017).1he prevalence of hypertension was significantly higher(83.3%va.66.2%,P=0.011).The proportion of patients with left ventricular systolic dysfunction was significantly higher(63.1% vs.45.9%,P=0.006),and plasma fibrinogen level increased significantly (mean [SD] 365 [108]vs.312[82] mg/dL,P=0.008).Conclusions:Plasma fibrinogen level is independently associated with a history of ischemic stroke in older patients with NVAF hospitalized for cardiac causes.

Objective To establish a mouse model of lymph node metastasis of breast cancer cells by luciferase imaging assay,to monitor early process of lymph node metastasis,and to evaluate the effect of X-ray radiation therapy on tumor.Methods The mouse mammary cancer cell line 4T1-Luc expressing luciferase was inoculated subcutaneously into the paw pad of nude mice to establish a model of subcutaneous lymph node metastasis.The lymph node metastasis in nude mice was continuously observed by in vivo fluorescence imaging system,and the nude mice with early lymph node metastasis of breast cancer cells were divided into control group and treatment group randomly.The radiotherapy effect was observed by in vivo fluorescence imaging system and evaluated by the pathological changes of HE staining of tumor tissue.Results A mouse lymph node metastasis model of breast cancer cells was successfully established,and the volume of primary tumor in paw correlated with the fluorescence photon number positively (r =0.958,P < 0.001).On the twenty-fourth day after inoculation,the fluorescence photon number in pad tumor and popliteal fossa tumor of treatment group were significantly decreased in comparison with the control group (t =32.58,P < 0.05),and the inhibition ratio of radiotherapy on tumor growth approached to 85 %.HE staining showed that the apoptosis and necrosis in irradiated tumor was obviously higher than that in control group.Conclusions Bioluminescence imaging technique can be used to evaluate the effect of X-ray on breast cancer suppression and lymph node metastasis in mice.

ObjectiveTo investigate the expression of miR-155 in whole blood of patients with breast cancer and explore the possibility of miR-155 in whole blood as a marker of beast cancer. Methods65 cases (breast cancer:47 cases, non-breast cancer:18 cases) in Thyroid and Breast Surgery Department of No.1 People's Hospital of Huai'an from Dec 2010 to Apr 2011 were enrolled according to the selected criteria.Two milliliters anticoagulant blood were sampled to isolate total RNA.The expression level of miR-155 in whole blood was measured by real-time quantitative polymerase chain reaction (real-time qPCR)analysis.The relationship between the expression level of miR-155 in whole blood and the clinical pathological fearutres was analyzed.ResultsThe expression level of miR-155 in breast cancer patients was up-regulated compared with that in non-breast cancer patients(P < 0.05).The expression level of miR-155 in patients with positive lymph nodes was up-regulated compared with that in patients with negative lymph nodes( P < 0.05).The expression level of miR-155 in stage Ⅲ breast cancer was up-regulated compared with that in stage Ⅰ & Ⅱ breast cancer( P < 0.05 ).The expression level of miR-155 in patients with positive ER and PR was down-regulated compared with that in patients with negative ER and PR breast cancer.Conclusion The study demonstrates that the expression of miR-155 in whole blood is related to clinical pathological features of patients with breast cancer and can be used as a potential marker of breast cancer.

This study aimed at evaluating the quality of the precise powder decoction pieces (PPDP) of L.japonicae Flos (LJF) compared with the traditional commercial slices with chemical fingerprint methods and DNA molecular identification technology.Different specifications of PPDP were prepared,their dry extract contents were in contrast with that of commercial slices.The three batches of commercial slices were collected,and the content uniformity,fingerprint and similarity evaluation before and after the mixing and pulverization were studied by HPLC-DAD and DNA sequence alignment.As a result,the paste rate of PPDP was slightly higher than that of the traditional commercial slices.The dissolution of chlorogenic acid of PPDP was higher than that of the traditional commercial slices.RSD of inter-assay dissolutions of chlorogenic acid of commercial slices was 11.93%,which was reduced to 8.29% after mixing and preparing into PPDP.The fingerprint showed that the slimilarity of the fringerprint of the mixed and powdered LJF was elevated with 7 common peaks.All the common peaks were increased at different levels.In conclusion,compared with traditional commercial slices of LJF,PPDP apparently improved the dissolution rate and the quality uniformity,indicating that the boiled powder of CRP obviously presented vantages in clinic.
