ObjectiveTo explore the effect of risk factors for coronary heart disease on the occurrence of heart failure in women with coronary heart disease. MethodsThree hundred and twenty-eight cases with coronary heart disease including 196 male patients (male group) and 132 female patients(female group) were selected. The risk factors of coronary heart disease including age, high blood pressure,diabetes, blood fat, plasma fibrinogen and blood uric acid were compared, all the patients were followed up for 1-3 years, the occurrence of heart failure was observed between the two groups, the level of blood uric acid was compared between patients with or without heart failure in female group. ResultsThe level of triacylglycerol, plasma fibrinogen and blood uric acid in female group was higher than that in male group (P ＜ 0.05 ). Followed up for 1-3 years, the occurrence of heart failure in female group was higher than that in male group[27.27％ (36/132) vs. 16.84％ (33/196)]. The level of blood uric acid in female group with or without heart failure was(368.85 ± 78.60) μ mol/L and(336.63 + 69.65 )μ mol/L, there was significant difference between the both (P ＜ 0.05 ). ConclusionsThe risk factors for coronary heart disease are the important dement in female coronary heart disease with heart failure, and blood uric acid is the alone risk factor. Through early monitoring the blood uric acid etc and intervention, the progress of the disease will slow.

OBJECTIVE: To determine the association between activity of BRAF and mitogen-activated protein/ extracellular signal-regulated kinase kinase (MEK) / extracellular signal-regulated kinase (ERK) signal pathway in papillary thyroid cancer and its mechanism. METHODS: We collected the clinical data and blood samples from 73 cases of papillary thyroid cancer and another 16 cases of benign thyroid gland tumor, and detected the expression of rat sarcoma (RAS), BRAF, MEK1/2, and ERK1/2 in all tumor specimens and benign thyroid tissues with immunohistochemistry and Western blot. RESULTS: The expression of RAS, BRAF, pMEK1/2, and pERK1/2 protein in papillary thyroid cancer tissues was higher than those in the benign thyroid tissues(P<0.05 or P<0.01). The expression of RAS, BRAF, MEK1/2, and ERK1/2 was associated with the tumor size, the lymph node metastasis, and the clinical stage of papillary thyroid cancer(P<0.05 or P<0.01). CONCLUSION The expression of RAS, BRAF, pMEK1/2, and pERK1/2 is associated with the pathogenesis, the lymph node metastasis, and the clinical stage of papillary thyroid cancer. The MEK/ERK signaling pathway may be activated by BRAF in papillary thyroid cancer.

OBJECTIVE: To determine the influence of v-raf murine sarcoma viral oncogene homolog B1 (BRAF) interference on SW579 cell lines in thyroid cancer. METHODS: We designed 2 pairs of siRNA interference sequences, transfected them into SW579 cell line with liposome, and detected the interference with RT-PCR method. For successfully interfered cell lines, the changes in cell proliferation, cell cycle, and the expression of related proteins in mitogen-activated protein signal-regulated kinase /extracellular signal-regulated kinase (MEK/ ERK) signal pathway were detected. RESULTS: After 2 pairs of siRNA transfection, the expressions of BRAF mRNA and protein of SW579 cell lines were significantly inhibited (P<0.01). The proliferation was inhibited, the cell cycle was changed, G1/S phase increased, and MEK/ERK signal pathway was inhibited. CONCLUSION Inhibition of growth and proliferation of SW579 cell lines by BRAF may be functioned by de-activating MEK/ERK signal pathway.
