Objective To explore the application value of layered suture technique in laparoscopic common bile duct exploration with primary suture. Methods A total of 216 patients received laparoscopic common bile duct exploration with primary suture in our hospital from March 2007 to March 2013.Of these cases, layered suture technique was utilized in 89 patients and single-layer suture was used in 127 patients.The operation time, postoperative hospital stay, and postoperative complications were compared between the two groups. Results Two groups of patients were operated smoothly, with no conversions to laparotomy.Postoperative recovery was smooth.The operative time was not significantly different between the two groups of patients (t=-0.931, P=0.353). The postoperative hospital stay and incidence of postoperative bile leakage were significantly lower in layered suture group than those in single-layer suture group [(5.9 ±1.7) d vs.(7.7 ±1.8) d,t =7.400, P=0.000;3.4%(3/89) vs.20.5%(26/127), χ2 =13.167, P=0.000].In the single-layer suture group, the incidence of postoperative bile leakage was significantly higher in patients complicated with acute cholangitis [45.4%(10/22) vs.15.2%(16/105),χ2 =8.429, P=0.004], whereas in the layered suture group, the incidence of postoperative bile leakage was insignificantly different among patients with and without acute cholangitis [7.1%(1/14) vs.2.7%(2/75),χ2 =0.002, P=0.964]. Conclusion Application of layered suture technique in laparoscopic common bile duct exploration with primary suture is feasible and safe, with advantages of less bile leakage and shorter hospital stay.

Objective:Our aim is to investigate the relationship of VEGF-C,VEGF-D and lymph node metastasis in pancreatic cancer,and to elucidate the role and significance of the cancerous peripheral lymphatic tissue.Methods: The expression of VEGF-C and VEGF-D was assayed by means of immunohistochemistry in 30 pancreatic carcinomas.Results:The positive rates of VEGF-C、VEGF-D were 73% (22/30)、57% (17/30) respectively in pancreatic cancer.The expression of VEGF-C、 VEGF-D in cancerous invasive edge was significantly higher than that in the center of cancerous tissues.There was no correlation between the expression of VEGF-C、VEGF-Dand the site,differentiation,histology types.Ⅲ~Ⅳ stages of pancreatic cancer showed strong expressions of VEGF-C、VEGF-D than that Ⅰ~Ⅱ stages of pancreatic cancer.The positive lymph node in positive VEGF-C and VEGF-D group were higher than that in the negative group.Conclusion:VEGF-C and VEGF-D induced lymphangiogenisis in pancreatic cancer,promoted the tumor cell lymph metastasis.

Objective To investigate the clinical distribution and the drug resistance of carbapenemresistant Proteus mirabilis strains isolated from 2009 to 2012 ; and to study carbapenemase genotypes of the isolates.Methods A total of 15 non-repetitive carbapenem-resistant Proteus mirabilis strains were selected from 422 Proteus mirabilis strains isolated from Ningbo First Hospital during January 2009 to December 2012.The minimal inhibitory concentrations (MIC) of 6 antibacterial agents,including imipenem (IPM),meropenem (MEM),ertapenem (ETP),ciprofloxacin (CIP),amikacin (AK) and minocycline (MIN),against 15 isolates were determined by E-test.The modified Hodge test (MHT) was used to detect the carbapenemase production in isolates.The PCR assay was performed to detect drug resistance genes of blaKPC,blaNDM-1,blaGES,blaSME,blaIMI-1/NmcA and blaSHV-38.Plasmids were extracted from the blaKPC-positive strains and then transformed into Escherichia coli J53 strains by electroporation.The transformed and untransformed Escherichia coli J53 strains were tested for MIC values and blaKPC gene by E-test and PCR respectively.Results The resistance rates of the 15 carbapenem-resistant Proteus mirabilis strains to IPM,MEM,ETP,CIP,AK and MIN were 100％,100％,100％,86.7％ (13/15),33.3％ (5/15) and 80％ (12/15),respectively.7 out of 15 strains were Hodge test positive,and 11 strains were blaKPC-2 positive.Results of PCR amplification showed that the transformed Escherichia coli J53 strains,whose MIC values to IPM,MEM,and ETP were increased by 2 to 64 times,were blaKPC-2 gene positive.Conclusion The carbapenem-resistant Proteus mirabilis strains in this study were resistant to many commonly used antibiotics,however,the resistance rates to AK were relatively low.The dominant carbapenemase genotype was blaKPC-2 carried by the plasmid.Attention should be paid to its easily transmissible feature among the strains in clinic.

A simple, rapid and sensitive method was developed for the quantification of tenofovir in plasma of Beagle dogs using HPLC-MS/MS analysis. The analytes tenofovir and internal standard (IS) adefovir were separated on a Zorbax SB-C18 column (3.5 microm, 100 mm x 2.1 mm, Agilent, USA) with mobile phase of methanol/water containing 0.3% formic acid using a gradient elution mode at a flow rate of 0.2 mL x min(-1). The plasma sample preparation was a simple deproteinization by the addition of 20% trichloroacetic acid followed by centrifugation. The detection was performed in positive selected reaction monitoring (SRM) mode with an electrospray ionization (ESI) source. The reactions monitored were m/z 288.1-176.2 for tenofovir and m/z 274.1-162.2 for adefovir (IS). Linear detection responses were obtained for tenofovir ranging from 10 to 5 000 ng x mL(-1). The intra- and inter-day precisions (RSD%) was no more than 6.3% with high recovery and good stability for the quantification, indicating the present method was specific, fast, accurate and reliable. The method was successfully applied to the pharmacokinetic study of two tenofovir agents. Tenofovir dipivoxil fumarate (BP0018, test agent) and tenofovir disoproxil fumarate (reference agent) were orally administrated to 8 Beagle dogs according to the 2 x 2 crossover design. Comparing with the reference agent, the longer MRT and t1/2 were obtained in the group of BP0018, while no significant difference was observed in AUC(0-t), AUC(0-infinity), C(max) and t(max) between them, suggesting that tenofovir dipivoxil fumarate was bioequivalent to the tenofovir disoproxil fumarate in Beagle dogs.

It is valuable to establish a chemical-pharmacokinetic (PK)-pharmacodynamics (PD) fingerprint of traditional Chinese medicine (TCM) for comprehensively understanding the TCM integrated conception and revealing the material foundation. The chemical, metabolic in vitro, and PK/PD in vivo fingerprints of Schisandra chinensis (SC) alcoholic extract were established and comparatively analyzed using HPLC-UV-MS method, rat liver microsomes in vitro and CCl4 intoxicated rats in vivo. Four known effective lignans, schisandrin, schisantherin A, deoxyschizandrin and gamma-schisandrin, were detected as the standard references in SC alcoholic extract with high concentration. SC alcoholic extract and four lignans when incubated with rat liver microsomes produced several metabolites in NAPDH-dependent manner. Chemical fingerprint of some components with bioactivities were also identified in PK and PD fingerprints in normal and ALI rats that explained the material foundation of SC alcoholic extract for multiple pharmacological effects. Schisandrin, schisantherin A, deoxyschizandrin and gamma-schisandrin could be considered as the "PK marker" of SC alcoholic extract or its relevant preparations, while two metabolites of the four lignans, 7, 8-dihydroxy-schizandrin and another one (M(W) 432), could be recognized as drug-metabolism (DM) Marker. This work provides experimental data for the further studies of metabolism or material foundation of SC components.
