Objective: To investigate the antihypertensive time-effect and dose-effect features of Sancao jiangya decoction(SCD).Methods: The blood pressure of spontaneously hypertensive rats at different time points were measured after treatment with Sancao jiangya decoction of low,middle,high concentration by tailartery blood pressure measurement for conscious rats.Results: The blood pressure was decreased at 2 hours after drug taken,there were significant dose-effect relationship between the antihypertensive effect and the low,middle,high dose.At 4h after drug taken,the high,middle dose had dose-effect correlation,but the low-dose had no antihypertensive effect.Further research on the middledose shows that the blood pressure reduced at 1h after drug taken,and the stable antihypertensive effect was keeping during 1-4h,the blood pressure began to rise at 6h,and got back to the level before drug taken at 8h.Conclusion: To choose the Middle-dose(10.4g crude drug/kg body weight) and 2h after drug taken is appropriate for SCD's use.This result laid a substantial foundation for further research on effects evaluation and mechanism of antihypertensive medicine.

ObjectiveTo observe the effects of D-limonene on lymphangiogenesis and lymph node metastasis in breast cancer. Methods Human breast cancer cell lines MDA-MB-435 were implanted into the mammary fat pad of 24 female nude mice to establish breast cancer model. The tumor volume and the incidences of lymph node metastasis were detected. Immunohistochemical staining was used to detect the lymphatic microvessel density and VEGF-C expression of the breast cancer tissues. Results In D-limonene group, tumor volume(0.824?0.31) and incidences of lymph node metastasis(25.0%) were significantly inhibited compared with control group (2.178?0.35,87.5%)(all P

Objective:To investigate the imaging manifestations and diagnosis of hepatic hereditary hemorrhagic telangiectasia (HHHT). Methods:The imaging features and clinical data of three HHHT patients were analysed and the related data were reviewed. B-type ultra-sonography, contrast enhanced CT and DSA were utilized to show the changes of the involved liver and the vessels. Results:B-type ultra-sonic graph showed abnormal blood vessels in hepatic hila. CT or DSA demonstrated intra-and extra-hepatic abnormal ectatic arteries, intrahepatic telangiectasia, cirrhosis and hepatic enlargement. Conclusion:CT might be used as one of the key measures for the diagnosis of HHHT.

Objective To investigate the therapeutic effect of the Hubei Wingnut ( Malus hapehensis ) leaf decoction (MHD) against conjunctivitis infected with human simplex virus type I (HSV-1). Methods Malus hupehcnsis decoction was used as the active treatment and ribavirin ( RBV) eye drop was used as the positive control. Both of the Vero cells and rabbit eye conjunctiva were infected with HSV-1. The effect and mechanism of the MHD on viral replication was determined by observing the cytopathic effect ( CPE) . The efficacy of MHD at different doses on the rabbit viral conjunctivitis was examined by pathological changes of eye conjunctiva tissues. Results MHD did not inhibit the proliferation of HSV-1 in vitro. The inflammatory reactions of rabbit viral conjunctivitis caused by HSV-1 were obviously attenuated or disappeared after treatment with MHD at 6 kg·L-1 and 3 kg·L-1 for 7 consecutive days,compared with the negative control of 0. 9% NaCl. The curative rate of MHD at the middle and high doses was 83. 3% and 100. 0%, respectively. Conclusion MHD has the potential for treating eye conjunctivitis caused by HSV-1 by relieving inflammation.

Background & Objective: The calcitonin gene-related peptide (CGRP) has a central role in the
pathogenesis of migraine, but variations in CGRP-related genes, including the calcitonin gene-related
polypeptide-alpha (CALCA) gene and the receptor activity modifying 1 (RAMP1) gene, have not been
found to link with migraine in Australian population. The goals of this study were to determine whether
variants in the two genes are related to migraine in Chinese population. Methods: Using a case-control
approach, rs3781719 and rs145837941 in the CALCA gene and rs3754701 and rs7590387 at the RAMP1
locus was analyzed in a cohort of 504 migraine cases and 529 ethnically matched controls. Genotyping
was performed using Sequenom MALDI-TOF mass spectrometry iPLEX platform. Results: The CALCA
gene rs145837941 variant was not found in migraine or control group. No significant difference in
genotypic and allelic distribution was observed in the other three polymorphisms between migraine
cases and controls. All the three SNPs were also not selected as significant factors that independently
contributed to susceptibility to migraine in multivariate analysis. In the subgroup analysis, the CALCA
rs3781719 seemed to be a significant risk for migraine with aura, but was not statistically significant
after FDR correction. Moreover, there was no synergistic relationship between the three SNPs in the
multifactor dimensionality reduction analysis for explore locus–locus interactions.
Conclusion: Our data suggested that variants in CALCA gene and RAMP1 gene were not associated
with migraine in the Han-Chinese population.

The relationship between tyrosine phosphorylation (TP) and protein expression of insulin receptor (InsR) and insulin resistance (IR) in patients with gestational diabetes mellitus (GDM) was investigated. The InsR expression and TP in skeleton muscle tissue were determined by Western blotting and immunoprecipitation in women with GDM (GDM group, n=22), normal pregnant women (normal pregnancy group, n=22) and normal non-pregnant women (normal non-pregnant group, n=13). Fasting plasma glucose (FPG) and fasting insulin (FINS) were measured by oxidase assay and immunoradioassay. The results showed that the levels of FPG (5.61±0.78 mmol/L), FINS (15.42±5.13 mU/L) and Homeostasis model assessment-IR (HOMA-IR) (1.21±0.52) in GDM group were significantly higher than those in normal pregnancy group (4.43±0.46 mmol/L, 10.56±3.07 mU/L and 0.80±0.31 respectively) (P<0.01). The levels of FINS and HOMA-IR in normal pregnancy group were significantly higher than those in normal non-pregnant group (7.56±2.31 mU/L and 0.47±0.26 respectively) (P<0.01). There was no significant difference in the InsR expression level among the three groups (P>0.05). TP of InsR with insulin stimulation was significantly decreased in GDM group (0.20±0.05) as compared with normal pregnancy group (0.26±0.06) (P<0.01). TP of InsR with insulin stimulation in normal pregnancy group was lower than that in normal non-pregnant group (0.31±0.06) (P<0.01). TP of InsR with insulin stimulation was negatively related with HOMA-IR in GDM group (r=-0.525, P<0.01). There was no correlation between the protein expression of InsR and HOMA-IR in GDM group (r=-0.236, P>0.05). It was suggested that there is no significant correlation between the protein expression of InsR in skeletal muscle and IR in GDM, but changes in TP of InsR are associated with IR in GDM.
