Objective To explore the role of endogenous and exogenous β-glucuronidase( β-G) in the development of primary common duct stones.Method Using modified Fishman method to test the activities of the endogenous and exogenous β -G in 35 patients with primary common duct stones(experimental group) and 11 patients with cystic polypus (control group) respectively.Results The activities of endogenous β -G in the bile of experimental group and control group were (7859.1 ± 738.5 ),(2174.9 ± 348.4 ) U/L(P ＜0.01).While the activities of exogenous β-G in experimental group and control group were (6786.1 ±544.3),(1504.7 ±655.7) U/L (P ＜0.01).In experimental group,there were significant statistical differences in the activities of the exogenous β -G in the sample obtained on the day of operation and 7 days after operation from 13 cases with the acute inflammation [(8935.7 ± 845.9),(2176.1 ± 956.7) U/L]and from 22 cases with the chronic inflammation [(5137.2 ±540.7),(1838.8 ±733.3) U/L],and there were significant higher in the activities of the exogenous β -G in the sample obtained on the day of operation from the acute inflammation compared to those from the chronic inflammation (P ＜ 0.05 ).Conclusions There is obvious correlation between either endogenous or exogenous β -G with primary common duct stones.And the endogenous β -G might be one of the fundamental cause in the development of primary common duct stones.

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.

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.

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.

Objective To apply the optical coherence tomography(OCT) to detect the characteristics of coronary artery plaque and to investigate its correlation with levels of serum matrix metalloproteinase 7(MMP 7),MMP9 and MMP12.Methods The patients undergoing coronary arterial angiography for diagnosing coronary arterial lesions in the cardiology department of our hospital from October 2014 to March 2016 were collected and included into the research subjects.The subjects were divided into the stable plaque group and unstable plaque group based on the results of OCT scanning.The neovascularization characteristics such as the fibrous cap thickness of plaque,angle of lipid pool,macrophage infiltration and plaque cracks were detected by using OCT.ELISA was used to measure serum MMP7,MMP9 and MMP12 levels.Results (1) The fibrous cap thickness in the stable plaque group was more than that in the unstable plaque group(P＜0.01);the lipid pool angle,microphage infiltration,intima erosion and plaque cracks in the unstable plaque group were more than those in the stable plaque group(P＜0.05).(2) The MMP7 and MMP9 levels in the unstable plaque group were higher than those in the stable plaque group and control group(P＜0.05).(3) The fibrous cap thickness had significantly negative correlation with serum MMP9 level(r=-0.336,P=0.034);the MMP7 and MMP9 levels in the microphage infiltration group were higher than those in the non-microphage infiltration group(P＜0.05);the MMP9 level in the intima erosion group was higher than that in the non-intima erosion group(P＜0.01).Conclusion OCT can detect and find unstable plaque and the serum levels of MMP7 and MMP9 are significantly elevated in the patients with unstable plaque,which can be used as an important basis for predicting unstable plaque and guiding the treatment decisions.
