Objective To develop a systematic chromatography separation method for flavonoids from Glycyrrhiza uralensis Fisch. (GU). Methods A new method for the separation of effective parts and monomers of flavonoids from GU by two-dimensional reversed-phase liquid chromatography was developed using the self-developed preparation chromatography plant system with independent intellectual property rights. Flavonoids compounds were enriched with specific adsorption materials. The separation conditions of the chromatography were optimized by the chromatographic separation expert system software, and the loading weight of samples and the enrichment times of a separation were investigated. Results The process of chromatography separation of flavonoids from GU had good precision and reproducibility with C18 as separation and enrichment solid phase and the methanol/water and acetonitrile/water as mobile phase of one-dimensional and two-dimensional chromatography system. The dilution solution which used for one-dimensional and two-dimensional enrichment chromatography was water. The flow rate of gradient elution and dilution enrichment solution was 21 mL/min. The sample loading amount of chromatography separation was 300 mg each time. A total of 16 flavonoids parts contained stable chemical composition were obtained by the repeatable separation method after three times of enrichment. Nine pure compounds were obtained and identified by NMR and MS, which were liquiritin, liquiritigenin, formononetin, echinatin, 7,4'-dihydroxyflavone, 4'-O-[β-D-apio-D-furanosyl-(1→2)-β-D-glucopyranosyl] liquiritigenin, isoliquiritigenin, glycyrol, and glycycoumarin. Conclusion The study can provide a certain reference value for the systematic separation and cognition for flavonoids from GU.

The Her-2 proto-oncogene encodes a 185kDa transmenbrane glycoprotein p185 which has intrinsic tyrosine kinase activity. It is overexpressed in several malignant human tumors like breast cancer. A chimeric antibody by assembling a single-chain Fv antibody and a human IgG1 Fc fragment was constructed. This chimeric antibody reacts with tumor surface antigen p185c-erbB-2 specifically. In order to put the antibody into clinical application, two steps purification method was used to attain the antibody’s purity more than 95%. Both the lyophilized pharmaceutical formulations of the antibody were found. The formulations can keep the stability and activity of the antibody for at least one year. These results were the foundation of the chimeric antibody for cancer therapy.

Objective To study the clinicopathological features of primary and metastatic hepatic neuroendocrine carcinoma.Methods The records of 35 patients with primary hepatic neuroendocrine carcinoma and 35 patients with metastatic hepatic neuroendocrine carcinoma were retrospectively reviewed.These patients served as the primary group(priNET,n=35)and the metastasis group (metNET,n=35),respectively.Results There were significant differences between the two groups of patients in gender,site,size and number of tumor(P＜0.05).Although there was no significant difference between the two groups in the distribution of the tumors in the two lobes of liver (P＞0.05),priNET had more tumors localized to one lobe of liver while metNET had more tumors involving both lobes of liver(P＜0.05).Conclusions Gender,size,site and number of tumor may play an important role in the differentiation of primary or metastatic hepatic neuroendocrine tumor.
