AIM　To find new anticancer drug based on the structure of podophyllotoxin. METHODS AND RESULTS　4-Deoxy-4β-arylmethylenesulfonylamido-4′-demethylpodophyllotoxins were (1-15) synthesized and their antitumour activities against KB cells and L1210 leukemia cells were tested. CONCLUSION　These compounds are new compounds. Among them, compounds 2, 3, 8, 9, 11 and 12 showed antitumour activities. When halides exist on the aryl ring of substituted sulfonyl group, the corresponding compound has relatively higher activities. The stereo factor is important for the activities.

With the surge of high-throughput sequencing technology, it is becoming popular to perform the phylogenetic study based on genomic data. A bundle of new terms is emerging, such as phylogenomics, pharmacophylogenomics and phylotranscriptomics, which are somewhat overlapping with pharmaphylogeny. Phylogenomics is the crossing of evolutionary biology and genomics, in which genome data are utilized for evolutionary reconstructions. Pharmaphylogeny, advocated by Prof. Pei-gen Xiao since 1980s, focuses on the phylogenetic relationship of medicinal plants and is thus nurtured by molecular phylogeny, chemotaxonomy and bioactivity studies. Phylogenomics can be integrated into the flow chart of drug discovery and development, and extend the field of pharmaphylogeny at the omic level, thus the concept of pharmacophylogenomics could be redefined. This review gives a brief analysis of the association and the distinguished feature of the pharmaphylogeny related terms, in the context of plant-based drug discovery and sustainable utilization of pharmaceutical resource.

For promoting the quality evaluation of Gardenia resource,a UPLC method for the determination of 4 compounds (geniposidic acid,geniposide,crocin-1 and crocin-2) in Gardeniae Fructus was established.The UPLC separation was performed on an Waters Acquity UPLC BEH-C18 (2.1 mm× 100 mm,1.7 μm) column eluted with the mobile phases of acetonitrile-0.1％ formic acid solution in a gradient mode at a flow rate of 0.3 mL· min-1.The detection wavelengths were 240 nm and 440 nm,respectively.Under the optimum conditions,the calibration curves of four analysis were linear in the range of 0.0065-0.0096 μg· mL-1,with correlation coefficients more than 0.9995.The limits of detection (LODs) of four analysis were in the range of 0.0386-0.1875 μg· mL-1.As the results of determination of 4 compounds of 12 batches of Gardeniae Fructus showed,there was great differences between the contents of the 4 compounds,the contents of geniposide were 2.44％-6.96％,while the contents of crocin-1 were 1.26％-3.04％.In addition,fingerprints of 12 batches of Gardenia resources were built using ChemPattern software,and analysis and exploration over the detection results of several samples were carried out using multivariate statistical method (similarity analysis,principal component analysis and cluster analysis).The present study provided a reference to value the importance of this method in the quality evaluation and quality control of Gardeniae resources and slices.

ObjectiveTo study the effect of exercise on expression of p38 after cerebral infarction in rats.MethodsThe right middle cerebral artery was occluded(MCAO) with electric coagulation in Wistar rats,and then were divided into three groups at random 48 hours later: training group which were given wheel-running exercise everyday(n=20);control group(n=20) and sham group(n=10).The expression of p38 in cortex of the three groups were detected on 7th,14th,21th and 28th day after the MCAO.ResultsIn the cortex around the infarcted focus,the expressions of p38 elevated much significantly after cerebral infarction(P<0.05).The expression of p38 in training group were higher than those in control group(P<0.05) on the 21th and 28th day.ConclusionThe cerebral infarction could induce the expression of p38.The exercise could enhance its expression.

This article was aimed to compare the antioxidant activities of Green tea and four tree-type non-Camellia teas. The antioxidant activities of the water extract of Green tea, Eagle tea, Large-leaved Kuding tea, Shiya tea and Qingqianliu tea were evaluated with four different in vitro assays including 1,1-diphenyl-2-picryl-hydrazyl (DPPH), ferric-reducing antioxidant power (FRAP), ferrous ion-chelating (FIC) and β-carotene-linoleate bleaching assay. In addition, the polyphenol contents of different teas were estimated by the Folin-Ciocalteu assay. The results showed that Shiya tea had strong antioxidant activity; its FIC and FRAP abilities are better compared with Green tea. The Eagle tea and Large-leaved Kuding tea have better antioxidant activity. The FRAP activity of Large-leaved Kuding tea was better than green tea. The DPPH of Eagle tea and Large-leaved Kuding tea were slightly lower than Green tea, but higher than the butylated hydroxytoluene (BHT). The antioxidant ability of Qingqianliu tea was the lowest. It was concluded that Shiya tea, Eagle tea, Large-leaved Kuding tea had relatively high development value which re-quires in-depth research and promotion.

Objective To investigate the relationship between the expression of inhibition of apoptosis proteins like p53,survivin,bcl-2 and chemosensitivities in gastrointestinal tract carcinomas.Methods The expression of p53,survivin and bcl-2 were determined immunohjstochemically,and the chemosenisitivities to 9 drugs was measured by MTT assay in 84 tissue specimens of gastrointestinal carcinomas.Resuits Positive immunostainning for p53,survivin and bcl-2 were found in 64%,89%and 61%of cases.respectively.Correlation existed between the expression of Sllrvivin and bcl-2(r=0.3027,P＜0.05).In terms of relationship between expression of p53,survivin or bcl-2 and inhibition rates of tumor cells.the inhibition rates to PTX and DDP in p53 strong expression group were lower than those in weak group(t=2.1282,P:0.0363;t=3.8850,P=0.0002).When survivin expressed strongly,the inhibition rates for VCR and DDP decreased significantly(t=2.1693,P=0.0329;t=2.0247,P=0.0046),while that for OXA increased(t=-2.9070,P:0.0047).here were lower tumor inhibition rates for 5-FU.VCR,eADM and OXA in bcl-2 strong expression group than those in weak group(t=2.1483～3.2330,P=0.0347～0.0018,respectively).Conclusions The extent of the expression of P53.survivin or bcl-2 in gastrointestinal carcinomas was associated with the chemosensitivities of some drugs.In assessing the influence of p53,survivin or bcl-2 on durg resistance,many factors and mechanisms should be considered.

Purpose To explore the practical significance of TERC gene amplification by fluorescence in situ hybridization ( FISH) on the differential diagnosis of cervical intraepithelial neoplasias 1 and 2 by tissue microarray. Methods A total of 42 cases of cervical tissue samples were selected, including 20 cases of normal cervix, 22 cases of cervical intraepithelial neoplasia (CIN) 1/2 (8 cases of CIN1 and 14 CIN2). Homemade tissue microarray was prepared. TERC gene amplification was detected with FISH method. Results TERC gene showed no amplification in the normal cervical squamous epithelium. TERC gene amplification was detected in 22. 7%(5/22)CIN1 and 77. 3%(17/22) in CIN2. 1/8 cases of TERC gene amplification in CIN1, 4/14 cases of TERC gene amplification in CIN2. There were significant differences in TERC gene amplification between those groups (P<0. 05). Conclusion The method is feasible and reliable in the detection of TERC gene amplification in CIN1/2 on paraffin sections. It has practical values in differential diagnosis between CIN1 and CIN2.
