Object To set up the quantitative method of baicalin in Gegen Qinlian Decoction (GQD) by RP HPLC and to determine the change of baicalin contents in decoctions prepared from various combinations of GQD. Methods By L 8(2 7) orthogonal design and statistics analysis (SPSS10 0), eight decoctions with Radix Scutellariae either alone or incombination with one or more of the other three components were prepared or analyzed. Contents of baicalin in them were determined by RP HPLC. Results It was significant (P0 05) and interactions between two of three were insignificant either. In this experiment, the sedimentation was found in the decoctions contained Radix Scutellariae and Rhizoma Coptidis. Conclusion The content of baicalin is reduced by Radix Puerariae and Rhizoma Coptidis, The resolution of baicalin is not increased by Radix Glycyrrhizae Preparata. Maybe the change of pH leads to the sedimentation in decoctions contained Radix Scutellariae and Rhizoma Coptidis.

Objective: To investigate the expression of PDCD5 in tissues of normal cervix, CIN Ⅰ-Ⅲ,cervical cancer and explore the relationship between PDCD5 and cervical cancer.Methods: After we defined the most fitful condition, tissues from 18 cases of normal cervix, 19 of CIN Ⅰ, 18 of CIN Ⅱ, 20 of CIN Ⅲ and 18 of cervical cancer were defined by indirect immunohistochemical technique. Positive expression rates and intensity of PDCD5 protein were investigated by observing under microscope and analyzing with computer imaging technique. The results were analyzed with one way anova. Results: The results of immunohistochemical staining showed that the percentage of strong positive cells in normal cervical tissue and CIN Ⅰ were significant higher than those of CIN Ⅱ, CIN Ⅲ and cervical cancer. On the whole of the condition of immunohistochemical staining, the expressions of PDCD5 were downregulated along the progression of cervical atypical epithelia, but that in CIN Ⅰ was upregulated.The ODs of normal cervix,CIN Ⅰ-Ⅲ,cervical cancer were 0.322,0.366,0.287,0.252,and 0.206 respectively.The intensity of each group showed obvious differences.Conclusion: We found that the expression of PDCD5 was upregulated in CIN Ⅰ and downregulated in CIN Ⅱ, CIN Ⅲ and cervical cancer. It suggests that PDCD5 is an important apoptosis regulating factor in the occurrence of cervical cancer.

Objective To observe the effectiveness and safety of oral anticoagulants and antithrombotic therapy in elderly patients with atrial fibrillation. Methods Patients were divided into anticoagulant group (warfarin) and antithrombotie group (aspirin or clopidogrel) based on the initial treatment. The prothrombin time (PT), activated clotting time (ACT), international normalized ratio (INR), activated partial thromboplastin time (APTT), fihrinogen (FIB), thrombin time (TT), coagulation factor Ⅱ,Ⅴ,Ⅶ,Ⅷ,Ⅸ, and Ⅹ,fibrin degradation product (FDP) and D-dimer were tested at baseline and after therapy in both groups. Results The average treatment period was 44.2±37.5 months in antithrombotic group and 39.0±61.5 months in anticoagulant group. There were six cases of isehemic stroke, one acute artery embolism in right lower limb and three gastrointestinal bleeding in antithrombotic group, while two gastrointestinal bleeding and two fatal hemorrhagic stroke in anticoagulant group. The results of PT, ACT, INR, APTT, FIB, TT, coagulation factor Ⅱ,Ⅴ ,Ⅶ, Ⅷ,Ⅸ,Ⅹ,FDP and D-dimer had no significant differences compared with the baseline in antithrombotic group. However, there were significant increase in PT and INR [(8.4±7.5)s and (0. 93±0. 83)s, both P<0. 05)], and significant decrease in ACT, coagulation factor Ⅱ,Ⅶ, Ⅸ and Ⅹ (all P<0. 05) in anticoagulant group. Conclusions Anticoagulant therapy may he effective in prevention of ischemic stroke in elderly patients with atrial fibrillation. However, it may slightly increase the hemorrhage incidence. The overall adverse events were not significantly reduced.

Background and purpose:Inlfammatory bowel diseases (IBD) are a group of chronic intestinal diseases, including ulcerative colitis (UC) and Crohn’s disease (CD). This study identified differentially expressed miRNAs in UC, CD and colitis-associated colorectal cancers (CAC) to explore their potential as novel molecular biomarkers. Methods:Tissue samples were taken from 13 UC patients, 3 CD patients, 12 CAC patients, and 8 age-and gender-matched healthy controls. The miRNA expressions were detected by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) assay. Known targets of deregulated miRNAs were utilized using miRWalk 2.0 database, and subsequent bioinformatics analysis of these target genes was performed by DAVID software (GO-analysis, KEGG-analysis and BIOCARTA-analysis). Results:The data showed that miR-146a, miR-27a, miR-29a, miR-20a and miR-21 were upregulated in UC, CD and CAC tissues compared with normal control. Moreover, the target genes of these miRNAs were enriched in several key signal transduction pathways including cancer-related pathway and immu-nity-associated pathway. Conclusion:miR-146a, miR-27a, miR-29a, miR-20a and miR-21 may play important roles in the switching from IBD to CAC.

Objective To investigate the markers in early diagnosis of acute kidney injury (AKI) in patients undergoing heart surgery.Methods Markers included serum cystatin C (CyC),and urinary neutrophil gelatinase-associated lipocalin(NGAL),interleukin 18(IL-18),retinol binding protein(RBP)and N-acetyl-β-D-glucosaminidase(NAG).Twenty-nine cardiac surgical patients hospitalized were enrolled in the study.Serial blood and urine samples were collected immediately before incision and at various time intervals after surgery.The primary outcome measure was AKI.defined as a 50%increase in Scr from baseline. Results The cohort consisted of 29 patients aged(62.9±13.7)years,and baseline Scr was(73.2±11.9)μmol/L.There were no significant differences in demographics between cases and controls,while the aortic clamp time was predictably longer in AKI cases as compared to controls[(60.63±13.92)vs(43.00±9.20)rain,P<0.05].Each biomarker difiered significantly between cases and controls at least one timepoint.Optimal AUCs were for CyC at 10 houm with sensitivity (ST)0.71,specificity(SP)0.92,AUC=0.83(0.67-1.00),cut-off(CO)1.31 mg/L;NGAL at 0 hour with ST 0.84,SP 0.80,Auc=0.85(0.70-1.00),CO 49.15 μg/g Ucr;IL-18 at 2 hours with ST 0.85,SP 0.73,AUC=0.81(0.64-0.97),CO 285.65 ng/g Ucr;RBP at 0 hour with ST 0.75,SP 0.67,AUC=0.77(0.60-0.95),CO 2934.65μg/g Ucr and NAG at 4 hours with ST 0.86,SP 0.67,AUC=0.72(0.53-O.92),CO 37.05 U/mg Ucr.Using a combination of all the 5 biomarkers analyzed at the optimal time-point as above,an AUC of 0.98(0.93-1.02)(P<0.01)in this limited sample was able to obtain. Conclusions Application of serum and urinary biomarkers for the prediction of AKI in patients undergoing cardiac surgery is highly dependent on the sampling time.Of the evaluated markers,uNGAL has the best predictive profile.uRBP also shows similar predictive power.Combining all the five above biomarkers is able to predict significantly more cases,suggesting that the use of more than one marker may be beneficial clinically.

Objective To investigate the role of recombinant human interleukin 6 (rhlL-6) in calcification and osteogenic transition of cultured human umbilical artery smooth muscle cells (HUASMC), and the possible cell signal transduction way. Methods HUASMCs were isolated by the explant method. HUASMCs were treated with (treatment groups) or without (control group) rhIL-6. Alizarin Red S stain was applied for calcium deposition in extracellular matrix of control ceils and the cells treated with rhIL-6 50 μg/L at day 12. Calcium concentration in cell layer of control group and treatment group (treated with rhIL-6 10 μg/L and 50 μg/L, respectively) was determined calorimetrically by the o-cresolphthalein complexone method at day 3, 6, 9 and 12, and corrected by total cell proteins. The mRNA expressions of bone-specific alkaline phosphatase (BAP), osteopontin (OPN), bone morphogenetic protein-2 (BMP2) and osteoprotegerin (OPG) were estimated by real-time PCR in 12, 24 and 72 hours. OPN, BMP2 and OPG expressions were assessed by Western blotting and the BAP concentration at the same time was checked by fluorometry method . Electrophoretie mobility shift assays (EMSA) was used to detect the binding activity of transcription factor Cbfα1 with or without inhibitors of p38-MAPK (SB203580) and PKC (DHC) after 6 hours stimulation by rhIL-6 10 μg/L. Results rhIL-6 induced a positive Alizarin Red S stain and a time-dose-dependent increasing of cell layer calcium deposition.Compared with control group, rhIL-6 10 μg/L enhanced gene expression and protein levels of BAP and BMP2 at the early time (12 and 24 hours), and of OPN and OPG at later hours (24 and 72 hours). RhIL-6 still induced an increasing of binding activity of Cbfα1, which could be partially blocked by DHC but not SB203580. Conclusions rhIL-6 induces HUASMCs calcification and osteogenie transition in vitro, which may be one of the mechanism involved in IL-6 associated vascular calcification as observed in clinical studies. The role of IL-6 in HUASMCs may partially achieved through the PKC cell signal transduction way.
