This study aimed to explore the value of animal energy metabolism monitoring system (AEMMS) to evaluate the energy metabolism of acute alcohol liver injury in rat with the treatment of acupuncture.Tirty rats were randomly divided into the control group,the model group and the EA group.The model group and the EA group were gavaged with 50％ ethanol for the establishment of the animal model of acute alcoholic liver injury.EA was given by needling Zusanli (ST-36) 30 min after intragastic administration every day in the EA group.The treatment of acupuncture continued 3 days.In addition,the RER,heat,feeding and drinking were continuously recorded for 96 h in each group at the same time by AEMMS.As a result,the RER,feeding and drinking indices significantly decreased in rats with ALI with an increase in the heat index.There was an up-going tendency of the RER,feeding and drinking indices,and a declined tendency of the heat index in the model rats after EA treatment.It was concluded that AEMMS presented a practical value in the study of the energy metabolism of rats with ALI with the treatment of acupuncture.

Objective Through constructing prokaryotic expression vector pET-30a-GPI-B7-1, to gain purified GPI-B7-1 fusion protein so as to confirm the tumor immune effect. Methods The DNA fragment encoding the signal for GPI-anchor attachment of hPLAP-1 and the cDNA encoding the human costimulatory molecule CD80 ( BT-1 ) were cloned from fresh placenta and human peripheral blood monocytes (PBMC) respectively. The two fragment were annealed to form a fusion gene (GPI-BT-1) by PCR. Then the fusion gene was inserted into the prokaryotic expression vector pET-30a, resulting in pET-30a-GPI-BT-1. Transfer to E. coli BL21, purified fusion protein were analysed by SDS-PAGE and Western blot. Results Agarose gel electrophoresis map of GPI and BT-1 PCR products show that GPI goal gene strap was seen at 133bp region and BT-1 goal gene strap at 792 region. Identification of recombinant pET-30a-GPI-B7-1 by restriction enzyme and PCR illustrate two goal fragment for 5000 bp and 900 bp, to realize the expression of fusion gene ( GPI-B7-1 ) at the E. coli BL21. The fusion protein was successfully produced in the pET expression system induced by IPTG and purified by Ni2 + -NTA agarose column. By SDS-PAGE and Western blot analysis, the observed molecular weight of the fusion protein was 38 kDa. Conclusion The purified GPI-B7-1 fusion protein can be obtained from E. coli BL21 transfered by prokaryotic expression vector pET-30a-GPI-B7-1, which will prove useful tool for the study of tumor immune therapy.

Objective To investigate SCCmec genotypes and drug-resistance profiles of the methieillin-resistant Staphylococcus epidermidis (MRSE) strains isolated from the patients suffered from diabetic foot infections (DFI) in the Tianjin Metabohc Diseases Hospital. Methods After dabridement, specimens of 390 infectious diabetic foot ulcers in the hospital from Jan 2008 to Jun 2010 were collected from the wound basal parts by cotton swab for culture. The disk-diffusion method was performed to examine antimicrobial susceptibility. DNAs of the MRSE strains were extracted, and their SCCmec genotypes were identified by PCR. Results Twenty of the seventy(28.6% ,20/70)Staphylococcus epidermidis strains were mecA posifive. Among the MRSE isolates, 2 ( 10.0% )were SCCmec Ⅱ ,9 (45.0%)were SCCmecⅢ and 9 (45.0%)were SCCmec Ⅳ. None of the isolates were genotyped as SCCmec Ⅰ or Ⅴ. No mater which genotypes they were, all the MRSE isolates were multi-drug resistant. They were resistant not only to β-lactams (including penicillins, cefoxitin and cephems), but also to non-β-lactams (including macrolides, fiuoroquinolones and sulfonamides ) . Resistance to voncomycin and rifampicin were not found in these strains . Conclusion SCCmec Ⅲ and SCCmecⅣ are major genotypes of the MRSE isolates from the infectious diabetic foot ulcers.The SCCmec Ⅳ genotype strains with multi-drug resistant profiles are prevalent in the diabetic foot infections.

Objective To evaluate the concept of artery first and total mesopancreatic excision in radical resection of pancreatic head carcinoma through both anterior and posterior approaches.Method The anterior approach was to identify the superior mesenteric artery (SMA) and the posterior approach to confirm the possibility of negative margin at the origin of SMA,on the posterio-lateral vascular wall of superior mesenteric vein (SMV) and the supposed posterior of the mesopancreas.The resection scope were with the celiac trunk and common hepatic artery as the upper boarder,the SMA as the left boarder,the inferior mesenteric vein (IMA) level as the lower boarder,to achieve a complete mesopancreatic excision,namely the en bloc resection of all the involved nerve,the lymph tissue and vascular tissue along the right side of the axial composed by SMA and celiac trunk.Results Of the 15 patients,11 had radical Whipple procedure,among which 2 had a combining SMV resection and reconstruction.1 case suffered from delayed gastric emptying and 2 cases from bile leakage.There was no mortality.The postoperative pathology reported carcinoma in all 11 cases,with duodenum and low bile duct involved in 4 cases,with the duodenum involved in 6 cases,no surrounding tissue involvement was identified in 1 case.Nerve involvement was found in 7 (7/11),vascular involvement in 10 (10/11),and lymphnode metastasis was (2.5 ± 3.8/12.9 ± 4.9).Conclusions The radical resection of pancreatic head carcinoma using the concept of artery first and the total mesopancreatic excision is helpful for an early evaluation of the possibility of radical resection and guarantees negative margins.
