Using proliferating inhibition test, the effects of three cultivars of black mushroom on the growth of gastric carcinoma cell in vitro were observed. We have found that the extracts of all three cultivars of black mushroom had inhibiting effects on the growth of tumor cells in medium at some levels, especially Cr-02 was the most evident one.The results suggest that black mushroom has some anti-tumor effects, and it is worthwhile to study farther for verification.

Objective To establish a method for detection of RhD(+) red blood cells mixed in D-negative blood by flow cytometry(FCM).Method RhD(+) and RhD(-) RBCs were mixed according to predefined ratios.Cells were indirectly labeled,with IgG anti-D labeled as the first antibody,and FITC-anti-IgG F(ab')2 as the second antibody.The percentage of RhD(+) RBCs was determined by FCM,and the best dosage of IgG anti-D was also defined.The ratio of red cells in the two groups,measured by FCM,was compared with the actual ratio.The consistency of method was also evaluated.Results The effective dosage of IgG anti-D was 1∶4,and 50?l/1?106 cells.When the actual percentages of RhD(+) cell among RhD(-) cells were 2.5%-0.312%,the correlation coefficient between the percentages measured by FCM and the actual percentages was 0.987.The same tubes,containing 10% and 2.5% RhD(+) RBCs,were each tested for 10 times,and their coefficient of variation were 3.4%,and 4.9%,respectively.Conclusion The method of quantifying the RhD(+) RBCs in D-negative blood by FCM is feasible and repeatable,which deserves a further clinical application.

OBJECTIVETo really realize quality control of Chinese herb purifying process, near-infrared spectroscopy (NIRS) was used not only for fast monitoring quality-control index of the process, but also for fast judgment of absorption endpoint.

METHODThe purification process of Carthamus tinctorius extracts with nonionic macroreticular resin was selected as an example. HPLC was used as the reference method to determine the content of HSYA. Quantitative and qualitative detection modes of purification were developed by NIRS combined with partial least squares (PLS) and moving block of standard deviation (MBSD).

RESULTThe correlation coefficient of the calibration model was 0.999, and the RPD for calibration and validation were above 5, of 5.54 and 5.22, respectively. Based on acquisition spectra, absorption endpoint calculated by MBSD was close to that by HPLC, Only 1 min deviation.

CONCLUSIONThe method mentioned above is proved to be convenient, rapid and nondestructive, and is applicable for fast monitoring the content of HSYA and fast judgment of absorption endpoint in purifying process of C. tinctorius extracts.

To investigate the effects of traditional Chinese compound recipe Yiqi Zengmin (YQZM) formula on expression of glucose transporter 4 (GLUT4) in skeletal muscle of rats with type 2 diabetes induced by high-fat diet combined with low-dose-streptozotocin injection.

Objective: To observe the protective effect of Silybin Capsules (SC) on mice hepatic toxic injury induced by isonicotinic acid hydrazide (INH) and rifampin (RFP) when used in combination Methods: The serum level of ALT, liver index, contents of glutathion (GSH) and malondialdehyde (MDA), activity of microsomal cytochrome P450 and its isoform P4502E1 in liver were measured. Results: SC obviously inhibited the rising of liver index, serum ALT, liver MDA and the activity of microsomal cytochrom P450 and its isoform P4502E1, and increased the liver GSH. Histopathological examination showed that Silibinin Capsules evidently alleviated the condition of the degeneration of hepatic cells and that of necrosis. Conclusion: The protective effect of SC on mice hepatic injury induced by both IIVit and RFP may be related to stabilizing the liver membrane, inhibiting the the lipid peroxidation, scavenging the free radical and decreasing the activity drug metabolizing enzyme.

Objective To examine the effects of IL-10 on cardiac fibroblasts ( CFBs) proliferation and phenotype transformation to myofibroblasts (MyoFbs) induced by transforming growth factor-β1 (TGF-β1);and to investigate the regulating pathways .Methods Cardiac fibroblasts were isolated from cardiac ventricles of neonatal SD rats . The passage 2~4 were used and divided into the following groups for treatment:1) control group, 2) IL-10 reac-tion group, 3) TGF-β1 reaction group, and 4) IL-10 plus TGF-β1 reaction group (TGF-β1 treatment followed with IL-10 pretreatment ) .Cells proliferation was assessed by MTT assay and immunocytochemistry staining for prolifera-ting cell nuclear antigen (PCNA);the phenotype transformation into MyoFbs was assessed by immunocytochemistry of α-smooth muscle actin (α-SMA);extracellular signal related kinase ( ERK1/2) and P38 kinase pathways were assessed by western-blot.Results TGF-β1 (10 μg/L) treatment boosted the proliferation and the expression ofα-SMA significantly (P<0.01), while IL-10 (10, 50 or 100 μg/L) plus TGF-β1 co-treatment induced lower cell proliferation and expression of α-SMA than treating with TGF-β1 alone ( P<0.05 ) , with the inhibitory effect of IL-10 being concentration dependent .TGF-β1 could significantly stimulate the ERK 1/2 and P38 kinase phospho-rylation ( P<0.01 ) , however IL-10 (100 μg/L) plus TGF-β1 co-treatment failed to down-regulated the phospho-rylation of ERK1/2 and P38 kinase compared with TGF-β1 alone ( ERK1/2:P<0.05;P38:P<0.01 ) .Conclu-sions IL-10 can attenuate TGF-β1-induced CFBs proliferation and phenotype transformation to MyoFbs .The in-hibitory effects may explained by a mechanism of inhibiting the activation of ERK 1/2 and P38 kinase .

Based on target cycling amplification and 3 ,4 ,9 ,10-perylenetetracarboxylic dianhydride derivative functionalized singal probe, an ultrasensitive electrochemiluminescence ( ECL) sensor was designed for the detection of lead ions. The hairpin substrate DNA was immobilized on the electrode through molecular self-assembly. In the presence of Pb2+and DNAzyme, the substrate was cleaved with single strand DNA fragments left on the electrode surface. Meanwhile, the target and DNAzyme was released for another cleaving circularly. As a result, the single strand DNA fragments hybridized with the assist hairpin probe H1, which leaded to the fabrication of H2 labeled with the 3 , 4 , 9 , 10-perylenetetracarboxylic dianhydride derivative functionalized hollow gold nanoparticles. With the increasing concentration of Pb2+, much more signal probe was been captured and the ECL signal of the biosensor in peroxydisulfate ( S2 O2-8 ) solution would increase. An ECL assay demonstrates that the sensor has a good linear response to Pb2+ concentration in the range of 1í10-12 mol/L-1í10-6 mol/L, with a detection limit of 1í10-12 mol/L. The fabricated sensor shows good selectivity toward Pb2+against other common metal ions.
