Objective To observe the effect of ligustrazine hydrochioridc(LHC) injection on TGF-β1 -induced proliferation and type IV collagen secretion in the human mesangial cells(HMCs). Methods The interstitial fibrosis in kidney disease was mimicked by inducing proliferation and type IV collagen secretion in HMCs with TGF- β1. The experiment was divided into 5 groups: blank, control, low, medium, and high(10, 30, and 100 μg/ml)ligustrazinc hydrochloride groups. MTT method was adopted to examine the proliferation and inhibition rate of HMCs. Enzyme-linked immunosorbent assay was used to determine the production of type IV collagen in cultured HMCs. Results LHC at high concentration (100 μg/ml) significantly inhibited the proliferation of HMCs (P<0. 01). LHC also inhibited the production of type IV collagen, with the significant inhibition found when at the concentration of 100 μg/ml (P

Objective: To establish an HPLC method for simultaneous determination of syringin, schizandrin, deoxyschizandrin and schisandrin B in Shuangwu capsules. Methods: The HPLC method was employed using a Diamonsil C18 column (200 mm X 4.6 mm, 5μm) with a mobile phase of methanol-acetonitrile (1 : 1, A) and water (B). The gradient elution program was as follows, 0-5 min, 35%-60%A; 5-10 min, 60%-70%A; 10-50 min, 70%-90%A; 50-90 min, 90%A. The flow rate was 1 ml/min. The detection wavelength was set at 220 nm and the temperature was at 35°C. Results: The linearity was obtained within the range of 1.28-20.40 μg/ml for syringin (r=0.999 7), 6.30-100.80μg/ml for schisantherin (r=0.999 6), 1.20-19.20μg/ml for deoxyschizandrin (r=0.999 8), and 3.75-60. 00 μg/ml for schisandrin B (r=0. 999 6). The RSD values of precision were less than 1% for all the four components. The results showed that the samples were stable in the room temperature for at least 24 h. The average recovery rates of syringin, schizandrin, deoxyschizandrin and schisandrin B were 99.47%, 102.50%, 99.21% and 101.86%, respectively. Conclusion: Our method is rapid, easy to perform and accurate; it can be used to control the quality of Shuangwu capsules.

A hallmark of small cell lung cancer (SCLC) is frequent relapse characterized by newfound resistance to formerly efficacious chemotherapies. The prognosis for SCLC patients is particularly unfavorable. Aurora kinase A (AURKA), a member of the serine/threonine kinase family, is overexpressed across many types of human tumors. Recent studies have identified AURKA as an important factor in tumorigenesis, but little is known regarding its specific roles in SCLC. The aim of the present study was to establish the roles of AURKA in the molecular pathogenesis of human SCLC. In the present study, we constructed a lentiviral vector to express siRNA against AURKA (LV-AURKA siRNA). As we expected, the viral construct effectively suppressed the expression of the AURKA gene and protein in H446 and H1688 cell lines. Additionally, RNA interference of AURKA inhibited the colony formation and subsequent growth of H446 and H1688 cell lines by increasing the incidence of cell cycle arrest in the G2/M phase. Furthermore, suppression of AURKA by LV-AURKA siRNA also increased apoptosis of SCLC cells. A potential mechanism for the increase of apoptosis is the downregulation of Bcl-2 and upregulation of Bax. AURKA gene suppression may provide a novel, effective therapy for SCLC patients by inhibiting cell division and increasing the rate of apoptosis of SCLC cells.

Objective: To evaluate the changes of plasma B-type natriuretic peptide(BNP) levels after high-pressure post-dilation following coronary stent deployment. Methods: A total of 173 patients undergoing percutaneous coronary intervention for the left anterior descending artery were enrolled into the study. All patients were divided into two groups: the conventional group and the post-dilation group. The plasma BNP, troponin I(TnI), myocardial band isoenzyme of creatine kinase(CK-MB) levels and the serum high sensitive C-reactive protein(hs-CRP) levels immediately before and 24 hours after the interventional procedures were compared between the two groups. Results: There were no significant differences between the two groups in terms of clinical features, clinical and biochemical parameters, stent parameters, pre-procedural plasma BNP and TnI levels, pre-procedural serum hs-CRP levels, as well as preand post-procedural CK-MB levels (all P>05). In the conventional group, post-procedural plasma BNP levels were significantly reduced when compared with the pre-procedural levels, median(25th,75th) were 32.5 ng/L(15.0,52.4) vs. 37.7 ng/L(18.2,67.3), P = 0.001. In the post-dilation group, post-procedural plasma BNP levels were significantly increased when compared with the pre-procedural levels, median(25th,75th) were 53.5 ng/L(29.6,82.8) vs. 44.2 ng/L(17.15,70.7), P,<.0001. Post-procedural plasma TnI levels were also significantly increased when compared with the pre-procedural levels in both groups, median(25th,75th) were 0.02 ng/L(0.01,0.08) vs. 0.01 ng/L(0.01,0.01), 0.05 ng/L(0.01,0.35) vs. 0.01 ng/ L(0.01,0.01), respectively, P,<.0001, so were the serum hs-CRP levels, median(25th,75th) were 3.3 mg/L(2.4,4.7) vs. 2.2 mg/ L(1.4,3.3), 4.2 mg/L(3.175,5.825) vs. 2.3 mg/L(1.45,3.6), respectively, P,<.0001. Post-procedural plasma BNP, TnI and serum hs-CRP levels in the post-dilation group were significantly higher than those in the conventional group(all P,<.0001). Conclusion: High-pressure post-dilation following coronary stent deployment resulted in a significant increase of plasma BNP levels, as well as plasma TnI levels and serum hs-CRP levels, which may be related to myocardial perfusion, more myocardial injury and more inflammation.

The adhesion mediated drug resistance in cancer cells resulted from adhesion of the extracellular matrix is a major cause for multidrug resistance (MDR) and leads chemotherapeutic failure for colon cancer. In this study, we explored the role of 67-kDa laminin receptor (67LR) in chemotherapeutic drug resistance in colon cancer cells. SiRNA-mediated knockdown of 67LR decreased the cell adhesion when laminins were applied. Moreover, 67LR knockdown increased the expression of pro-apoptotic gene Bax but inhibited the expression of anti-apoptotic gene Bcl-2. Enhanced apoptosis was observed in 67LR siRNA-transfected SW480 cell when the cell was treated with doxorubicin for apoptosis induction. Furthermore, MTT assay revealed that the IC50 of chemotherapeutic toward SW480 cell adhesion to laminins was reduced after 67LR knockdown, indicating there was a significant increase of drug sensitivity in SW480 cell. In conclusion, our study demonstrated that 67LR plays a considerable role in the development of colon cancer MDR. © 2015 International Society of Oncology and BioMarkers (ISOBM)
