Lymph node dissection was the key procedure of pancreatic surgery.The majority of guidelines indicated that extended lymph node dissection was helpless for improving survival rate.However,there were still quite a few researches which demonstrated that the extended dissection was a valuable procedure.It was still a controversial topic considering lymph node dissection.To review the shortcomings of previous randomized controlled trials (RCT),this article combined the experience of new techniques in pancreatic surgery,which are developing rapidly in recent years,and our theory and practice of radical resection of retroperitoneal lipo-lymphatic layer (RRRLLL).Therefore,the controversy and update of extended lymph node dissection for pancreatic head carcinoma were discussed,which could provide references for standardizing the treatment of extended lymph node dissection in clinical practice.

Xiao Zhi Ling Injection is a Chinese herbal aqueous solution of praeparatum which is mainly made of gallnut and alum, it can make a " strengthening body resistance " treatment in polytype tumors, mainly through promoting apoptosis of tumor cells, destructing tumor cells, inhibiting tumor growth, enhan-cing immunity of organism and so on, the clinical effect is certain, with the development of theory and tech-nology in tumor molecular biology, it has become the core of future research that how to further explore Xiao-Zhi-Ling injection to promote tumor cell apoptosis by impacting on related genes, and its lucubrate inevitably provide new hope in gene therapy of cancer.

Objective To investigate the antimicrobial resistance of Gram-positive cocci isolated from 17 hospitals located at different areas in China. Methods All the Gram-positive cocci isolated from 17 hospitals from October 1 st, 2004 to September 30th, 2005 were collected for susceptibility test using standard agar dilution method issued by The Clinical and Laboratory Standards Institute (CLSI,2004). The minimal inhibitory concentration (MIC)50 and MIC90 were detected for antibacterial activity in vitro of 35 antimicrobial agents. The rates of resistance, intermediate and susceptiblity of bacteria to the agents were calculated. Results Totally, 925 Gram-positive cocci strains were collected during the period, which included Staphylococcus 536, Enterococcus 249, Streptococcus 137 and other Gram-positive cocci 3; the rates of oxacillin resistant Staphylococcus aureus (ORSA) and oxacillin resistant Staphylococcus epidermidis (ORSE) were 62.9% and 82.9%, respectively. The penicillinnonsusceptible Streptococcus pneumoniae (PNSP) was 40.7 % including 10.5 % resistant and 30.2intermediate. All strains of Enterococcus were susceptible to teicoplanin. No Enterococcus was resistant to vancomycin. Five strains of Enterococcus were found intermediate to vancomycin, which were 1 E.faecalis, 2 E. faecium, 1 E. gallinarum and 1 E. avium. No glycopeptides resistant Gram-positive coccus was detected. Conclusions The antimicrobial resistance of Gram-positive cocci is increasing with higher isolate rate of penicillin-resistant Streptococcus pneurnoniae (PRSP) and methicillinresistant Staphylococcus aureus (MRSA). All the investigated Gram-positive cocci are highly resistant to macrolides. No glycopeptide resistant strains are detected during the surveillance.

Objective In order to find the polymorphism site applicable to efficient genetic diagnosis on Haemophilia A in Han Chinese Population in Wenzhou.Methods With the method of polymerase chain reaction(PCR) and polyacrylamide gel electrophoresis(PAGE),288 of X chromosomes from 96 men and 96 women were detected on the polymorphism of BCL I in the intron 18 of FV Ⅲ gene.Results The gene frequency of the polymorphic site BCL I was 34.38% in Han Chinese population in Wenzhou.43.75% women were heterozygous and the polymorphism information content(PIC) was 0.4512.Conclusion For Han Chinese population in Wenzhou,the BCL I genetic site has enough information,being one of the genetic markers with high polymorphism,applicable to the screening for carrier and prenatal diagnosis of Haemophilia A in Wenzhou.

OBJECTIVE: To determine ginsenoside Rg1 and ginsenoside Re in Jiangshen Capsules by HPLC simultaneously. METHODS: The separation was performed on Kromasil-C18 column, the mobile phase consisted of acetonitrile-0. 05% H3PO4 solution ( 21∶ 79) with flow rate of 1. 0mL? min-1 and detection wavelength of 203nm. RESULTS: The linear ranges of ginsenoside Rg1 and ginsenoside Re were 0. 502～ 4. 016? g( r=0. 999 7) and 1. 090～ 8. 720? g( r=0. 999 8) , respectively, with average recovery at 98. 8% ( RSD=1. 24% ) and 99. 4% ( RSD=1. 68% ) , respectively. CONCLUSION: This method is simple, rapid, accurate and reliable, and suitable for the quality control of Jiangshen Capsules.
