OBJECTIVETo investigate the antithrombotic effects and its molecular mechanisms of prazosin combined with anisodamine (Ani).
METHODSIsolated rat tail artery rings model was employed to evaluate the vasodilative effects of drugs, mice tail thrombosis model induced by carrageenan was used to study the antithrombotic effects and its molecular mechanisms of the drug composition.
RESULTSAmong alpha1-adrenoreceptor antagonists, prazosin(Pra) had the greatest relaxation rate, which was (82.6 +/- 8.9)%, and the EC50 value was 0.44 micromol/L. The drug composition of anisodamine and prazosin of different doses could decrease the length of the tail thrombosis from (24.6 +/- 4.6)mm to (6.9 +/- 2.7)mm, and the rate of thrombosis was decreased from 86.6% to 50.0%. The drug composition could prolong the prothrombin time (PT) distinctively, but it had no effect on the activated partial thromboplastin time (APTT). It also could restrain the decrease of serum levels of tissue plasminogen activator (t-PA) and 6- Keto -PGF1alpha as well as the increase of type-1 plasminogen activator inhibitor (PAI-1) and thromboxane B2 (TXB2) in the mice.
CONCLUSIONThe drug composition formed by anisodamine and prazosin has good effects of relaxing extremities tiny blood vessels and it can fight against thrombosis, its antithrombotic mechanisms may be related to the influence of the extrinsic coagulation pathway, inhibition of platelet activation functions and the promotion of fibrinolysis function.

Objective RNPC1 may act as an oncogene or suppressor gene in human tumors and its role in human renal cell carcinoma (RCC) remains unclear.The objective of this study was to investigate the role of RNPC1 in the development of RCC.Methods Over-expression of RNPC1 gene group (RNPC1 group) and short hairpin RNA interfering RNPC1 gene expression (shRNPC1 group) were respectively built in RCC CAKI-1 and CAKI-2.The blank control group (NC group) and negative control group (SCR group) were built as well.The qRT-PCR and western blot (WB) were used to detect the expression levels of RNPC1 mRNA and RNPC1 protein in RCC cells.Lentivirus infection was applied to establish stable expressed RCC cell lines of RNPC1 over-expression and interference.Detection was made on mRNA and protein expression levels in RNPC1 stable RCC cell lines.The effects of RNPC1 on cell proliferation, colony formation assay, migration, and invasion were detected by CCK-8 cell differentiation test, clone test, scratch test, and migration and invasion test.WB was applied to detect the change of protein expression in the EMT path of RNPC1 stable RCC cell lines and explore the molecular mechanism of RNPC1 effect on the biological function of RCC cells.Results The expression levels of RNPC1 mRNA and protein were found lower in shRNPC1 group than those in SCR group, while the expression levels of RNPC1 mRNA and protein in SCR group were higher than those NC group (P<0.05).The capability of proliferation in shRNPC1 group was stronger than that in SCR group, while the capability of proliferation in shRNPC1 group was weaker than that in NC group (P<0.05).The capabilities of cell migration and invasion were stronger in shRNPC1 group than those in SCR group, while the capabilities of cell migration and invasion in RNPC1 group were weaker than those in NC group (P<0.05).RNPC1 could inhibit the proliferation capability of RCC cells and might up-regulate the protein expression of E-cadherin and down-regulate the protein expression of β-catenin and vimentin, thus inhibiting EMT path and the capabilities of migration and invasion off RCC cells (P<0.05).Conclusion RNPC1 acts as a tumor suppressor in RCC and has the potential for the prediction of RCC prognosis.

Purpose To investigate the expression of EZH2 and p53 protein in breast cancer and to analyze their relationship with the clinical pathologic characteristics and prognosis. Methods The expression of EZH2 and p53 protein were detected by immunohisto-chemical method in 50 cases of breast adenosis tissues, 92 cases of breast invasive lobular carcinoma ( ILC) and 200 cases of breast in-vasive ductal carcinoma ( IDC) , and their correlation was also analyzed. Results There was no statistical significance of EZH2 be-tween ILC and IDC (P>0. 016 7), while its expression in breast adenosis tissues was lower than that in ILC and IDC (P<0. 016 7). In breast cancer the expression of EZH2 protein were not correlated with patient age, menopausal status, histological types, and pTNM stage. In contrast, its expression correlated with the tumor size, lymph node metastasis, molecular subtype, survival status and p53 (P<0. 05). There was no statistical significance of p53 between ILC and breast adenosis tissues (P>0. 016 7), while its expression in IDC was higher than that in ILC and breast adenosis tissues (P<0. 016 7). Its expression had no related to patient age, menopausal status, tumor size, lymph node metastasis in breast cancer, but related to histological types, pTNM stage, molecular subtype and sur-vival status (P<0. 05). The Kaplan-Meier survival analysis showed the expression of EZH2 and p53 had correlated with disease-free and overall survival rates of breast cancer (P<0. 05). Multivariate COX regression analysis showed that the expression of EZH2 and p53 were independent affecting factors to breast cancer patients. Conclusion The expression of EZH2 and p53 protein increase in the breast adenosis, ILC and IDC gradually, and they have positive correlation. The expression levels of EZH2 and p53 protein have im-portant value to evaluate the prognosis of breast cancer patients.

Purpose To investigate the clinicopathological characteristics and the survival outcomes of invasive lobular carcinoma. Methods A retrospective analysis of 98 patients with invasive lobular carcinoma and 530 invasive carcinoma of no special type was performed in order to observe the histological features and the clinical outcomes of invasive lobular carcinoma. Results Median follow-up was 68. 5 months for invasive lobular carcinoma and 67 months for invasive carcinoma of no special type. Invasive lobular carcinoma presented with a larger tumor size, more histopathological grade 2 tumors, increased rate of hormonal receptor positivity, human epider-mal growth factor 2 (HER-2) negativity, and had a lower proliferative index as compared to invasive carcinoma of no special type, more frequently presented with the luminal A subtype (P<0. 001). The classical invasive lobular carcinoma presented with a smaller tumor size, to have a lower histological grade and proliferative index compared to the non-classic type, and more frequently presented with the luminal A subtype, whereas the non-classic invasive lobular carcinoma patients more frequently presented with the luminal B, HER-2 overexpression, or triple negative subtype (P=0. 035). A statistically significant difference in the outcome was observed at un-ivariate analysis for patients with non-classic for disease-free survival (P=0. 043) and for overall survival (P=0. 048), as compared with patients with classical invasive lobular carcinoma. The disease-free survival difference between the invasive lobular carcinoma and the invasive carcinoma of no special type was not significant (P=0. 537), and the overall survival rates were not statistically different between the two groups (P=0. 397). A statistically significant difference of overall survival was observed at multivariate analysis for patients with HER-2 positive and triple negative subtypes versus patients with luminal A invasive lobular carcinoma (P=0. 015, P=0. 016) . Conclusions The outcome of invasive lobular carcinoma is significantly correlated with histological and immunohistochemi-cally defined molecular subtypes. New tailored strategies should be explored in these subgroups of patients with poor outcome.
