Objective To assay the level of neutrophil extracellular traps (NETs) in systemic lupus erythematosus (SLE) patients and healthy controls and compare the difference between SLE group and control group, and to analyze between the level of NETs and related laboratory parameters. Methods Forty-four females patients with SLE were recruited as research subjects, with 24 cases in the active stage and 20 in stable stage. Forty-two healthy female volunteers matched in age were enrolled as control subjects. The fluorescence intensity of NETs in neutrophils was detected by fluorospectrophotometry. The concentration of neutrophil elastase in plasma was quantitatively detected. Statistical analysis of the difference of level of NETs between the SLE group and control group was conducted. Then the correlation between the fluorescence intensity of NETs and erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), and anti-double-stranded DNA (dsDNA), and anti-histone, and anti-nucleosome, and systemic lupus erythematosus disease activity index (SLEDAI) was analyzed respectively. The same tests were conducted for the level of NE. The results of the two groups were compared using analysis of variance and the relevance was analyzed using Spearman correlation analysis. NETs morphosis was observated by immunoflurescence method, and the difference of NETs between SLE group and control group was analyzed. Results ① The fluorescence intensity of NETs was significantly increased in SLE group(241±139) than that in the control group (173±135), (t=2.31, P<0.05).②The concentration of NE in the SLE group (102±47) was significantly higher than that in the control group (62±22), t= 4.38, P<0.01. No difference of NETs [(274±168) vs (211±102), t=1.52, P>0.05] and NE concentration [(104±43) vs (96±48), t=0.50, P>0.05] between SLE active stage and stable stage was detected. ③ The fluorescence intensity of NETs in SLE patients was positively correlated with SLEDAI, but had no obvious correlation with anti-dsDNA, anti-histone, anti-nucleosome, CRP or ESR, respectively. ④Images under confocal microscope showed that more NETs generated by PMN from SLE patients than that from controls. Conclusion The generation of NETs is enhanced in female patients with SLE. And NETs may relate to disease activity. However, NETs may not induce the production of autoantibodies.

Evidence body is defined as an evidence complex incorporating the evidence obtained from various research methods and various resources. As one of common parenterally administered Chinese medicines, Shuxuetong's safety drew high concern from doctors. However, we only have grasped several but less systematic evidence on the safety of Shuxuetong. To build a safety evidence body of Shuxuetong injection. Review and evaluate the evidence related to the safety of Shuxuetong injection after accumulating, searching and classfying related literature. Accoeding to levels of evidence from high to low, the evidence related to the safety of Shuxuetong injection was classified as following: the evidence from a long-term, prospective, large-sample-size and intensive hospital monitoring study was the strongest; the evidence of hospital information system (HIS) data analysis; the evidence of spontaneous reporting system (SRS) data analysis; the evidence of adverse drugreactions (ADRs)/adverse drug events (ADEs) reported in systematic evaluation, ADRs case report, toxicological tests, pharmacological tests were weakest. Based on the evidence body, Shuxuetong Injection was proved to be safe, and its ADRs were mainly allergic reactions, and more often happened among the old patients.

The definition of critical quality attributes of Chinese materia medica ( CMM) was put forward based on the top-level design concept. Nowadays, coupled with the development of rapid analytical science, rapid assessment of critical quality attributes of CMM was firstly carried out, which was the secondary discipline branch of CMM. Taking near infrared (NIR) spectroscopy as an example, which is a rapid analytical technology in pharmaceutical process over the past decade, systematic review is the chemometric parameters in NIR model evaluation. According to the characteristics of complexity of CMM and trace components analysis, a multi-source information fusion strategy of NIR model was developed for assessment of critical quality attributes of CMM. The strategy has provided guideline for NIR reliable analysis in critical quality attributes of CMM.

Objective To explore the effect of chemokine CXCL12 and its receptor CXCR4 on proliferation,migration and invasion of epithelial ovarian cancer cells.Methods CXCR4 and CXCL12 mRNA and protein expression of human ovarian cancer cell line CAOV3 was detected by RT-PCR and immunocytochemistry.Integrin ?1 and vascular endothelial growth factor-C(VEGF-C)mRNA expression were detected in CAOV3 cells stimulated by CXCL12.The CAOV3 cells were divided into 6 groups:control group(un-stimulated),experimental group 1(stimulated by 100 ng/ml CXCL12),experimental group 2 (stimulated by 10 ng/ml CXCL12),experimental group 3(100 ng/ml CXCL12 and 10 ?g/ml neutralizing CXCR4 antibody),experimental group 4(100 ng/ml CXCL12 and 1 ?g/ml CXCR4 antagonist AMD3100),experimental group 5(10 ?g/ml neutralizing CXCR4 antibody or ascites).Methyl thiazolyl tetrazolium(MTT)was used to analyze the effects of different concentrations of CXCL12 on CAOV3 cell proliferation.Transwell invasion chamber and reconstructed basement membrane(Matrigel)were used to evaluate effect of various concentrations of CXCL12 and ascites on CAOV3 cell migration and invasion. Results CAOV3 cells expressed CXCR4 mRNA(0.70?0.10)and protein,but did not express CXCL12 mRNA or protein.Immunostaining of CXCR4 was mainly located in cytoplasm.CXCR4 mRNA was up- regulated after 100 ng/ml CXCL12 stimulation(1.24?0.14;t=-7.1088,P=0.0021).Integrin ?1 mRNA was greatly increased at 3 hours by stimulation of 100 ng/ml CXCL12(before and after stimulation 0.53?0.10,1.53?0.16;P0.05).Experimental group 1 stimulated the migration and invasion of CAOV3 cells in chemotaxis assay compared with control group and experimental group 2(number of cell migration respectively 523.3?25.2,108.0?7.2,211.7 ?24.7,number of cell invasion respectively 39.3?4.0,4.0?1.0,15.7?3.1;P

The five-flavor theory of traditional Chinese medicines (TCM) and the flavor efficacy generation mechanism has long been focuses and difficulties in studies on traditional Chinese medicinal properties. In this paper, by using the pharmacophore-based virtual screening technique, the authors discussed the relations between the pungent property and transient receptor potential vanilloid 1 (TRPV1) by studying the TCM components' role in regulating TRPV1 ion channel. The results showed that the matching relationship between TRPV1 agonist pharmacophore model and TCM chemical components could identify the active ingredients from pungent herbs. Therefore, the authors proposed that TRPV1 is one of the potential targets for efficient pungent herbs. The pungent property of TCMs is decided by its chemical components, and consistent with the inherited and additive characteristics.
