World Science and Technology-Modernization of Traditional Chinese Medicine 2017;19(3):424-431
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.

Chinese Journal of Minimally Invasive Surgery 2005;0(08):-
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 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 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

Objective To investigate the treatment of common bile duct or common hepatic duct transverse injures(CBDTI) in cholecystectomy.Methods From January 1993 to March 2008,3362 patients received cholecystectomy in our hospital,among them 5 developed CBDTI.We reviewed the clinic feature,management,and outcomes of these patients. Results Of the 5 patients,2 had common hepatic duct transverse injuries and 3 showed common bile transverse injuries.One of the five received postenterobiliary drainage and the other four underwent choledoch end-to-end anastomosis.No biliary leakage was found after the operation.One patient developed biliary stenosis and cholangitis after the end-to-end anastomosis and thus received postenterobiliary drainage.This case was followed up for 15 years,during which no abdominal pain,fever or jaundice occurred.The patient who underwent postenterobiliary drainage showed symptoms of cholangitis for 3 times whithin 2 months after the treatment;therefore,conservative therapy was carried out.Afterwards,the patient was cured and showed no abdominal pain,fever or jaundice during a 5-year follow-up.The other 3 patients who received end-to-end anastomosis were followed up for 1,2,or 4 years,no complications were noticed during the period.Conclusions Based on personal experience and the type of injury,surgeons may chose choledoch end-to-end anastomosis or postenterobiliary drainage to treat CBDTI.
