Using MS as basic medium, supplemented with 1.0 mg · L(-1) IBA, the adventitious roots of Tripterygium wilfordii were induced, and the good adventitious root culture system was established by leaves or callus induced by leaves as explants. The adventitious roots were also induced with 2.0-4.0 mg · L(-1) NAA and the good adventitious root culture system established by using suspension cells from callus as materials to induce adventitious root. The content of triptolide of three adventitious roots culture system were exceeded in the natural root bark. The content of triptolide of AR3 adventitious roots was the highest about 5.3 times as that in the natural root bark. By using 5 L stirred fermentor during pilot enlarge cultivation, compared with 250 mL flask cultivation, the adventitious roots increment and secondary metabolites content per liter medium showed no significant difference. The accomplishment of this analysis laid a foundation by tissue culture production of the secondary metabolites of T. wilfordii.

Objective To identify genes associated with hepatocellular carcinoma (HCC) as candidate diagnostic markers in a genome-wide scale. Methods The gene expression profiles of 40 pairs of HCC tumor tissue and peripheral non-tumorous liver tissue were analyzed by using gene chip technology.The gene chips were fabricated at the National Cancer Institute (NCI). Each gene chip contained 9 180 genes. The fluorescent targets were prepared by a direct labeling approach using two kinds of fluorescences as following: 100 ?g of total RNA from non-cancerous liver tissue was labeled with Cy3-dUTP and 200 ?g of total RNA from HCC was labeled with Cy5-dUTP. The targets were mixed together and hybridized with genes on the gene chips. Unsupervised hierarchical clustering analysis was done by CLUSTER and TREEVIEW software using median centered correlation and complete linkage. Results A total of 10 genes were found up-regulated in over 80% of primary tumors comparing with that of their corresponding non-tumorous liver tissues at a two-fold filter with an unsupervised hierarchical clustering algorithm, including protocadherin-alpha 9, ESTs, Homo sapiens cDNA FLJ, KPNA2, RPS20, SNRPE, CDKN2A, UBD, MDK and ANXA2. Conclusion These genes are supposed to be candidates for the diagnosis of HCC. Further investigation of these genes in a large scale of patients with HCC and patients with non-malignant hepatic diseases will be needed to disclose whether they could be used clinically as novel diagnostic tumor markers for HCC.

ObjectiveTo compare the therapeutic efficacies between acupoint thread embedding plus Western medication and dry Western medication in treating metabolic syndrome.MethodTotally 320 patients with metabolic syndrome were randomized into a treatment group and a control group, 160 cases in each group. The control group was intervened by ordinary Western medication, while the treatment group was by acupoint thread embedding in addition to the Western medication given to the control group, and Yishu (Extra), Geshu (BL17), Ganshu (BL18), Pishu (BL20), Shenshu (BL23), Tianshu (ST25), Daimai (GB26), and Guanyuan (CV4) were selected as the major points. The therapeutic efficacies, metabolism-related parameters, liver function, and kidney function were compared between the two groups, and the therapeutic efficacies of different syndromes were also compared.ResultThe markedly effective rate and total effectiverate of the treatment group were significantly higher than that of the control group (P<0.01). After treatment, there was no significant difference in comparing the HDL-C between the two groups (P>0.05), but there were significant inter-group differences in comparing the rest parameters including liver and kidney functions (P<0.05), and the treatment group was superior to the control group. Acupoint thread embedding produced a more significant efficacy in treating metabolic syndrome due to heat in liver-stomach and phlegm-dampness stagnancy compared to the control group (P<0.05), and the efficacy of acupoint thread embedding in treating metabolic syndrome due to phlegm-dampness stagnancy was significantly different from that of the control group (P<0.01).ConclusionAcupoint thread embedding plus Western medication can produce a more significant therapeutic efficacy in treating metabolic syndrome compared to Western medication alone, and it’s safe; of all the patterns, phlegm-dampness stagnancy responds thebest to acupoint thread embedding.
