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.

To study the mechanism of therapeutie effect of compound "Huang Dai" tablet in acute promyelocytic leukemia, twenty one patients with acute promyelocytic leukemia were treated with compound "Huang Dai" tablet. Bone marrow cells of the patients were collected before treatment and after treatment, and membrane differentiating antigen (CD33 and CD11b), cell cycle and the apoptosis correlative protein(Fas and Apo 2.7 )were detected with flow cytometry. Results showed that the expression of CD33 was decreased and that of CD11b increased, G 2 /M phase of cell cycle was blocked, and the expressions of Fas and Apo 2.7 protein were increased significantly in all patents after treatment with compound "Huang Dai" tablet. These results suggested that the mechanism of therapeutic effect of compound "Huang Dai" tablet in acute promyelocytic leukemia was induction of both differentiation and apoptosis of leukemic cells, and cell apoptosis might be related to Fas and Apo2.7 protein.

Objective To explore difficulties and countermeasures of laparoscopic cholecystectomy (LC) for treating huge gallstones. Methods Fifty-six cases of huge gallstones with a diameter of 2.0~5.3 cm (3.4?0.6 cm) were reviewed in respect of their clinical features and operative difficulties and countermeasures during laparoscopic cholecystectomy. Results The laparoscopic cholecystectomy was completed smoothly in 54 cases, with an operation time of 30~130 min (94.3?40.7 min). Conversions to open surgery were required in 2 cases because of acute suppurative cholecystitis. Moderate-to-severe adhesion was found in 41 cases (73%). White bile or absence of bile secretion was found in 23 cases (41%). There were 2 cases (4%) of small bile duct injuries in the gallbladder bed, 15 cases (27%) of liver tissue injures in the gallbladder bed, and 19 cases (34%) of intraoperative gallbladder leakage. No major bile duct injury or massive hemorrhage occurred. The postoperative hospitalization time was 3.6?1.5 days. Follow-up observations for 6~12 months (mean, 11 months) found that the symptoms disappeared and no complications were noted. Conclusions The difficulties during LC for huge gallstones lie in the thickening of the gallbladder wall that causes injuries of the liver tissue and small bile ducts in the gallbladder bed. Careful dissection and reservation of part of the gallbladder wall are effective methods to lower the incidence of complications.

Objective To investigate the diagnosis and treatment of latent perforation of peptic ulcer (LPPU) during laparoscopic cholecystectomy (LC). Methods A retrospective analysis was made on clinical data of 13 cases of LPPU diagnosed during LC from January 1994 to November 2005. Results All the 13 cases were misdiagnosed before the LC and clarified as having LPPU during the LC. Three cases of anterior duodenal bulbar perforation (0.4~0.5 cm in size) were laparoscopically repaired, whereas conversions to open repair were performed in 5 cases of duodenal perforation (0.5~1 cm in size) and 5 cases of gastric perforation (0.6~1 cm in size) because of severe adhesion or difficult performance. No surgical complications occurred. Twelve cases were followed for 6~36 months (mean, 27 months). The symptoms disappeared and gastroscopy showed healed ulcer. No recurrence of perforation was found. Conclusions Underestimation of LPPU leads to misdiagnosis, and preoperative gastrosopy can prevent it. For small perforation, laparoscopic repair and abdominal drainage can be employed. But in most cases, a conversion to open surgery is required. It is necessary to give regular internal medicine for peptic ulcer after operation.

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.
