A lot of research achievements have been obtained in the field of Chinese materia medica (CMM) in recent years,which have been paid close attention to by the international community.It also promotes the internationalization of traditional Chinese medicine (TCM).However,the genetic background of CMM bioactive compounds and the effect on human genes of CMM composition after ingestion are not clear.As a frontier technology,herbgenomics provides a new method for the study of biosynthesis,breeding of new varieties and the identification of CMM.It will also promote more achievements in this field.This paper reviewed the research progress of study on the frontier omics technology of CMM in order to provide references for CMM research.

Objective To investigate the laparoscopic treatment for giant intraabdominal cysts with postoperative lower body edema. Methods Five cases of giant intraabdominal cysts were given an aspiration of 1 500 ~ 2 000 ml (mean, 1 800 ml) of fluid. The aspiration was performed percutaneously in 2 cases of hepatic cyst, and under direct vision through a 1.5~2.5 cm incision around the umbilics in 3 cases of lower intraabdominal cyst. After aspiration the cysts were excised (3 cases) or fenestrated (2 cases) laparoscopically. Postoperative lower body edema was treated with diuretics either orally (2 cases) or intravenously (3 cases). Results Symptoms completely disappeared after operation in 4 cases and were significantly improved in 1 case of polycystic liver. Follow-up for 3~12 months found no recurrence. The lower body edema subsided in 5~7 days after operation. Conclusions Aspiration of cystic fluid before laparoscopic operation and postoperative administration of diuretics could get good results for patients with giant intraabdominal cysts.

The paper reports the establishment of a method for simultaneous determination of peimisine and sipeimine contents in Fritillaria walujewii Regel and Fritillaria pallidiflora Schrenk. The analyses were performed on an ultra-performance liquid chromatography with evaporative light scattering detection (UPLC-ELSD), equipped with a binary solvent manager, a sampler manager and a column compartment, and connected to Waters Empower 2 software. An Acquity UPLC BEH C18 column (100 mm x 2.1 mm, 1.7 microm) was used for all analysis. The investigated compounds were separated with gradient mobile phase consisting of acetonitrile-0.02% triethylamine-water. The temperature of sample manager was set at 25 degrees C. Drift tube temperature was 40 degrees C, and spray parameter was 40% with injection volume of 1 microL. The investigated compounds including peimisine and sipeimine had good linearity (r > or = 0.9991) over the tested ranges. The average recovery was 94.5% and 98.1% with RSD < or = 2.36%. The UPLC-ELSD method is simple, sensitive and accurate with good repeatability, which is available for quality control of F. walujewii Regel and F. pallidiflora Schrenk.

The paper is to report the establishment of a method of characteristic figure analysis for the quality control of Panacis Quinquefolii Radix. Application of HPLC-UV-ELSD techniques was connected in series and applied. The separation was carried out on the Agilent Extend-C18 (250 mm x 4.6 mm, 5 microm) column. The mobile phase consisted of water and acetonitrile with gradient elution. The flow rate was 1.0 mL x min(-1) and the wavelength of measurement was 203 nm. The temperature of drift tube was maintained at 106.5 degrees C and the flow rate of air was set at 2.9 L x min(-1). Twenty batches of the Panacis Quinquefolii Radix were determined. Hierarchical cluster analysis (HCA) and principal component analysis (PCA) were applied to study on the HPLC characteristic figure and chemical pattern recognition. The HPLC-UV and HPLC-ELSD characteristic figure of Panacis Quinquefolii Radix was developed, the ginsenosides Rg1, Re, Rb1, Rc, Rb2, Rb3, Rd and the pseudoginsenoside F11 were identified. This method is accurate and reliable, and it can be used to control the quality of the Panacis Quinquefolii Radix.

Objective To explore the effects of psoralen (PSO) and long wave ultraviolet A (PUVA) on apoptosis and expression of Fas in HL-60,K562 and NB4 leukemia cells.Methods The cells were incubated with PSO in different concentrations irradiated with or without UVA.The changes of ultrastructure of cells were observed under the electron microscope.The expression of Fas gene was detected by fluorescent quantitation PCR.The apoptosis ratio and the expression of Fas protein were detected through the flow cytometry.The factorial design and analysis of variance were used to analyze the interaction among the factors.Results There were obvious ultrastructure changes about apoptosis in leukemia cells after treated with PUVA.PSO,UVA and PUVA all increased the apoptosis ratio and expression of Fas gene and protein,and the effects of PUVA were stronger than the other two (P

Tumor necrosis factor ?(TNF ?) is a potent proinflammatory cytokine. In human, TNF ? gene is located within the highly polymorphic major histocompatibility complex(MHC) region on chromosome 6p21.3. TNF gene cluster contains many polymorphisms including microsatellites and single nucleotide polymorphisms(SNPs).Many of these polymorphisms were found to be in linkage disequilibrium with HLA class Ⅰand Ⅱ alleles. Some of the TNF ? gene polymorphisms were found to influence TNF ? production in vitro , for example the 308SNP. Many studies have shown that this SNP and others within the TNF ? gene associate with different inflammatory conditions. Whether this phenomenon is due to the direct influence if the SNP in question and/or due to linkage disequilibrium with other polymorphisms within the TNF ? gene or the HLA system is still controversial.

Objective To evaluate the value of vascular intervention in the diagnosis and management of hemobilia. Methods With Seldinger's technique ,digital subtraction angiography of superior mesenteric artery and hepatic arteriography were performed on 3 patients with hemobilia, two of whom manifested hemobilia after the operation of liver trauma and one of whom did after the operation of command bile duct stones . Arteriography showed the bleeding vascular branch, the false aneurysm and the arteriovenous fistula. And then a small catheter was put into the bleeding focus. The bleeding branch arteries were selectively embolized with embolus of n-butyl cyanoacrylate (NBCA),PVA granule,spring wire loop and gelatin sponge. Results Two cases showed diffuse bleeding focus and another showed a local bleeding focus. Two cases had expression of false aneurysm and one showed expression of ateriovenous fistula. The artery branches of the bleeding focus were successfully embolizated and the hemobilia stopped immediately. Conclusions Vascular intervention is an effective method for the diagnosis and management of hemobilia.

Objective To investigate the value of intraoperative choledochofiberscopy and B-ultrasonography for intrahepatic bile duct calculus. Methods After bile duct stone removal by routine instruments, choledochofiberscopy and B-ultrasonography were conducted for detecting and removing the residual cholelith in intrahepatic bile ducts. Results The incidence of residual cholelith was 29.8% (14 of 47) after stone removal by routine instruments, and it declined to 10.6% (5 of 47) ( ? 2=5.267, P
