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.

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 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 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.

Objective To explore the leaves water extract on the liver human hepatocellular carcinoma xenografts and protein expression of Bcl-2 and HSP70 .Methods From cell morphology and DNA agarose gel electrophoresis the observation leaves water extract the characteristics of the material role in human hepatoma cells ,further use of immunocytochemistry agent Western blotting analysis method oncogene Bcl-2 and tumor suppressor genes HSP70expression .Results After the processing of the the 60 mg/mL leaves water extract of liver cancer cells after 12 h ,liver cells showed severe shrinkage ,pyknosis ,highlight the cell plasma mem-brane ,immunohistochemistry and Western blotting analysis showed that during the experiment along with the oncogene Bcl-2 ex-pression weakened(P<0 .05) ,while the expression of tumor suppressor genes HSP70 had no obvious change(P<0 .05) .Conclusion Water extract of the leaves can be induced in vitro human liver cancer cell apoptosis ,and the apoptotic process may be followed by the oncogene Bcl-2 ,tumor suppressor gene expression of HSP70 relationship .

Objective To discuss the prevention and treatment of bile duct injures io the gallbladder bed during laparoscopic cholecystectomy(LC).Methods A retrospective analysis was made on clinical features,treatment,and curative effects of 15 cases of bile duct injures in the gallbladder bed out of 2 032 cases of LC from January 1997 to December 2004.Results There were 5 cases of acute attack of chronic calculous cholecystitis and 10 cases of chronic atrophic calculous cholecystitis.The location of injury was at the branches of the right hepatic ducts in 8 cases and at aberrant bile ducts in 7 cases.The injury was treated with titanium clipping in 8 cases,primary suture in 5 cases,and open surgery of bile duct repair in 2 cases because the injury was relativly large and the site of injury was near the trunk of the right hepatic duct.Postoperatively,bile leakage happened in 1 case and was cured by drainage for 5 days.Follow-up surveys for 6~36 months (mean,23 months) showed free of symptoms and no jaundice or cholangitis.Conclusions Surgical dissection closely near the gallbladder wall when mobilizing the gallbladder is the key to preventing bile duct injuries in the gallbladder bed during laparoscopic cholecystectomy.Prompt detection and proper management of the injury have satisfactory curative effects.
