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 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 develop a kind of mobile Bluetooth temperature sensor with removable measurement and wireless transmission.Methods The device was designed with technology of high precision sensor and newly developed Bluetooth base on MCU MSP430 as control unit which could apply in real time measurement,data storage,transmission and emergency alarm.Results The problem that at the scene of many cables in clinical care of the devise was resolved.Any devices with Bluetooth sensor can receive temperature data.Conclusion The traditional work mode is changed by the Bluetooth device and reduces the workload of nursing staff,which provides a new solution for integration of Bluetooth and clinic care technology.

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 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.

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.
