OBJECTIVE:To investigate the inhibitory effect of ligustrazine on the formation of macrophage-derived foam cells and its possible mechanism. METHODS:Human acute mononuclear cells (THP-1) were incubated with 160 nmol/L phorbol ester (PMA) for 24 h to differentiate into macrophages;and the macrophages were incubated with oxidized low-density lipoprotein (ox-LDL)culture solution containing 80 mg/L for 24 h to differentiate into macrophage-derived foam cells. And then the cells were randomly divided into blank control group(ox-LDL),model(AngⅡ)group,positive control(valsartan)group,and ligustrazine low,medium and high concentration groups(the mass concentration were 0.025,0.05 and 0.1 g/L). After all cells were respective-ly incubated with 80 mg/L ox-LDL culture solution for 48 h,oil red O staining was adopted to observe the transformation rate of foam cells,enzyme chemical method was used to determine the content of cholesterol,and real-time quantitative polymerase chain (RT-PCR)and Western blot were conducted to detect expression levels of Acyl-coenzyme A cholesterol acyltransferase-1(ACAT-1) mRNA and its protein. RESULTS:Compared with blank control group,the transformation rate of foam cells and content of choles-terol in model group were increased,and the expression levels of ACAT-1 mRNA and its protein were obviously strengthened,with significant differences(P<0.01 or P<0.05). Compared with model group,the transformation rate of foam cells and content of cho-lesterol in positive control group(valsartan)and ligustrazine low,medium and high concentration groups were decreased,and the expression levels of ACAT-1 mRNA and its protein were obviously weakened,with significant differences (P<0.01 or P<0.05). CONCLUSIONS:Ligustrazine can inhibit the macrophages differentiating into foam cells,by a mechanism that may be related to inhibiting expression of ACAT-1,and reducing content of cholesterol to reduce formation of foam cells.

OBJECTIVE:To prepare rapid-disintegrating oral tablets of indometacin and establish a method for its quality control.METHODS:The formula of the oral tablets was optimized by orthogonal test with the formula quality of CMS-Na(A),L-HPC(B),MCC(C),manniton(D) as factors,and the disintegrating time as index.The content of indometacin was determined by ultraviolet spectrophotometry.RESULTS:The optimal formula of the tablets was the following,A∶B∶C∶D=5∶5∶50∶5.The preparation was white in color and its quality was up to the related standard specified in Chinese Pharmacopeia (2005 edition) in identification.The linear range of indometacin was 2.08～41.6 ?g?mL-1 (r=0.999 9).The average recovery was 99.3%.The intra-day RSD=0.53% and inter-day RSD=0.74%.CONCLUSION:The preparation is simple and feasible in preparation process,and controllable in quality.

Objective To investigate the clinical value of blood recovery in the heart valve replacement surgery of adults. Methods Selected 556 patients accepted cardiac valve replacement surgery from May 2008 to April 2012 in our hospital,and divid-ed into control group(278 cases)and observation group(278 cases)according to the way of intraoperative blood transfusion patients in observation group underwent autologous blood recovery and patients in control group underwent without autologous blood recov-ery,the clinical parameters were observed and statistically analyzed.Results The differences of blood routine after 24 h(such as he-moglobin,hematocrit,platelets,etc.)and blood gas analysis(such as pH,potassium ions,lactic acid,etc.)between two groups were not significantly different,which is statistically insignificant(P >0.05);the postoperative chest drainage of patients in observation group was not significantly different from that of patients in control group,which was statistically insignificant(P >0.05);the a-mount of banked blood in observation group(263.83 ± 19.23)mL was significantly lower than that in control group(615.24 ± 20.34)mL,the difference between two groups was statistically significant(P <0.05).Conclusion In heart valve replacement sur-gery of adults,blood recovery can effectively add blood volume,reduce autologous blood loss,and significantly reduce the amount of banked blood input,which is worthy of promotion.

Objective To investigate the effect of different doses of propofol on cytokines-tumor necosis factor-? (TNF-?), interleukin-6 ( IL-6 ), interlenkin-8 ( IL-8 ), during systemic inflammatory response syndrome (SIRS) .Methods Fifty-six male Wistar rats weighing 190-220g were anesthetized with intraperitoneal 2.5% pentobarbital 30mg.kg-1 . The animals were randomly divided into 4 groups of 14 animals each: group A received intraperitoneal saline 10ml.kg-1 followed by intravenous infusion of saline (2ml.h-1 ); group B received intraperitoneal LPS 1mg.kg followed by intravenous infusion of saline(2ml.h-1 ) ; in group C propofol was infused iv at 75?g.kg-1.min for 4h after intraperitoneal LPS injection; in group D propofol was infusion iv at 150?g.kg-1 .min-1 for 4h after intraperitoneal LPS injection. Blood samples were taken before experiment and 1, 2, 3, 4h after saline or propofol infusion for determination of serum TNF-? (cytotoxin stain method) and IL-6, IL-8 (ELISA) concentration.Results Serum concentrations of TNF-?, IL-6 and IL-8 induced by LPS increased significantly in group B as compared with those in group A. Propofol decreased the level of cytokines and delayed the peak values of TNF-? and IL-8. Conclusion Propofol used in the early stage of SIRS has some protective efficacy.

Objective To investigate The effect of TAM(2.5 uM)in the chemotherapy of HCC and its mechanism. Methods An adriamycin-resistant human HCC cell subline(Hep-3B/ADM)was established,through exposure to gradually increased concentration of ADM.Drug sensitivity was measured by MTT.Modulation of ADM-induced apop- tosis of Hep-3B/ADM cells was assessed by Flow cytometry(FCM).PKC activity was determined by applying compet- itive protein binding method.Results TAM(2.5uM )decreased the IC50 of ADM from 1.64?g/mL to 0.23?g/mL in the Hep-3B/ADM cells.TAM exhibited a 2-fold potentiation on apoptosis caused by ADM in Hep-3B/ADM cells.With TAM,PKC activity was lower than that in control groups from 30 seconds to 24 hours.But this effect of TAM could be reversed by the co-treatment of the cells with TPA.Conclusion TAM(2.5 uM)significantly en- hanced ADM-induced cytotoxicity.The mechanism is that TAM potentiates the apoptosis induced by ADM through pro- tein kinase C inhibition.

Objective:To analyze the genetic sequence characteristics of amomum viosum and establish a rapid identification meth-od for amomum viosum by fluorescent quantitative PCR based on DNA analysis. Methods:Amomum viosum and the other samples be-longing to the same genera were collected and identified by experts in the domain. DNA was isolated using commercial kits. The prim-ers and probe were designed according to the conserved region of ITS in amomum viosum. The reaction conditions were optimized to es-tablish the fluorescent quantitative PCR method for the rapid detection of amomum viosum. Results:The fluorescent quantitative PCR method for the rapid detection of amomum viosum was set up. The method could identify amomum viosum successfully, while those samples in the same genera were without amplification curves. Conclusion: Amomum viosum can be identified rapidly by fluorescent quantitative PCR besides the traditional identification by experts.
