OBJECTIVE To investigate the distribution and resistance of non-fermenting bacteria isolated from(patients) in 2005 and offer a basis for the treatment of bacterial infection.METHODS The isolated bacteria were(identified) with API identified test(API Inc,France) and Kirby-Bauer(K-B) test used for the antibiotics(susceptivity) test.The data were analyzed by using WHONET-5 software.RESULTS Totally 604 strains of non-fermenting bacteria were isolated from the 2908 pathogenic strains.The most common bacteria were Pseudomonas aeruginosa(52.32%),followed by Stenotrophomonas maltophilia(14.07%) and Acinetobacter baumannii((13.74%)).76.32% of non-fermenting bacteria were isolated from the sputum.These bacteria had various(resistances) to all detected antibiotics.CONCLUSIONS Non-fermenting bacteria have high isolation rate and(multi-drug) resistance,so antibiotics should be used correctly under the guidance of antibiotic susceptibility testing.

According to the principle of immunomagnetic separation, a novel high-efficient immunomagnetic isolator termed as CMSI 100 for the purification of human CD34 + hematopoietic cells was designed and successfully developed. To do this , neodymium iron boron having magnetic properties superior to any other permanent magnet materials was selected as the key parts of CMSI 100 isolator. The core of the magnet assembly was constructed by sandwiching mild steel bars between 4 pieces of magnet bars of neodymium iron boron. Each piece of magnet bars must be limited to the specifications of 3.5cm?2.0cm?0.3cm so that 2 700 gauss magnetic attractive force could be exerted at the magnet surface. Otherwise magnetic field above the surface of the magnet assembly is either very stronger or weaker, both of which are not beneficial to the enrichment of CD34 + hematopoietic cells. With CMSI 100 immunomagnetic isolator, more than 90% purity and over 95% viability of CD34 + hematopoietic cells could be obtained. These data indicate that CMSI 100 immunomagnetic isolator is as good as the internationally used Isolex TM 50 made by Baxter Company in USA.

Objective To clone the human target gene HBVDNAPTP1 transactivated by hepatitis B virus DNA polymerase obtained by screening with suppression subtractive hybridization (SSH) and bioinformatics techniques. To construct prokaryotic expressive vector of HBVDNAPTP1 gene, induce the expression of recombinant protein in E. coli, and analyze the expression level of HBVDNAPTP1 gene in human tissues. Methods The DNA fragment of HBVDNAPTP1 was amplified by reverse transcription polymerase chain reaction (RT-PCR) taking mRNA from HepG2 cells as the template, and the correct DNA fragment was then inserted into inducible prokaryotic expressive vector pET-32a (+). The competent BL21 (DE3) E. coli was transformed, and then cultured and induced with IPTG. The expressed HBVDNAPTP1 was confirmed with Western blot. UniGene database was used to analyze the chromosome mapping and tissue expression profile of HBVDNAPTP1 gene. Results The DNA fragment of HBVDNAPTP1 was amplified by RT-PCR. HBVDNAPTP1 expressive vector was constructed. After transformation with pET-32a(+)-HBVDNAPTP1 and induction with IPTG, recombinant HBVDNAPTP1 was expressed and confirmed by Western blot. The expression of genomic location of HBVDNAPTP1 gene was low in multiple-tissues with the exception of pituitary gland, tonsil, tongue, thymus, trachea and umbilical cord. Conclusion The recombinant HBVDNAPTP1 gene could be expressed in prokaryotic expression system of E. coli. The chromosome mapping and tissue expression level of HBVDNAPTP1 gene is tentatively conceived.

Objective To clone and sequence variant-specific surface antigen gene from Giardia lamblia isolate SUCH/89/BTMRI/2(C2) derived from human in China. Methods Total genomic DNA of G.lamblia was extracted and a full-length variant-specific surface antigen gene fragment was amplified by pelymerase chain reaction (PCR). The PCR product was cloned into pMD19-T simple-vector, transformed into an Escherichia coli JM109 strain and then sequenced. The sequence analysis for cloned fragment was finished by Vector NTI 9.0 software for the homology of Giardia variantspecific surface antigen gene to that of sequences publishend in GenBank. Results The full-length variant-specific surface antigen gone fragment from G. lamblia was found to be 2 142 bp, encoding a 713 amino acid polypeptide and contained a single open reading frame (ORF). The deduced polypeptide sequence was rich in cysteine (11.8 mol%), most of which occurred with in 29 copies of the 4-amino acid CXXC motif, one GGCY-tetrapeptide motifs and three NXS consensus N-linked glycosylation sites. This polypeptide was also rich in threonine (10.2 mol%), glycine (12.1 mol%) and alanine (10.1 mol%). Like other previously identified VSPs, it contained a highly conserved hydropbebic Cterminal region. The homology of G. lamblia SUCH/89/BTMRI/2(C2) variant-specific surface antigen gene to that of sequence (TSA417) published in GenBank was 99% both at the nueleotide and the amino acid levels. Conclusion The full length variant-specific surface antigen gene from the isolate of G. lamblia has the common characteristics with other previously identified VSPs.

Trehalose, a compatible solute, is widely used in food, cosmetics, pharmaceutical products and organ transplantation. Nowadays, trehalose is mostly produced by enzymatic synthesis with many secondary products and lowpurity. In this study, high amount of trehalose was produced by recombinant E. ccli fermentation. First, a bifunctional trehalose gene TPSP was amplified from genome of C. hutchinscoii. Second, an expression vector pTac-HisA containing TPSP was constructed and transformed into the host E. coli. Expression of this bifunctional enzyme-TPSP converted glucose to trehalose. The result suggested that TPSP from C. hutchinsonji has been successfully expressed in E. ccoi. High amount of extracellular trehalose generated from glucose by whole-cell catalysis and After optimization, the production of trehalose in shake flasks was improved to 1.2 g/L and the relative conversion rate reached 21%. The production in bioreactor reached 13.3 g/L and the relative conversion rate reached 48.6%. It is the first time to realize the functional expression of the bifunctional enzyme-TPSP of C. hutchinsonii in E. coli and achieved the conversion form glucose to trehalose. This study laid a foundation for industrial large-scale production of trehalose.

Articular cartilage defects are common, which is one of the important factors leading to joint degeneration. Due to lack of vascular supply, the ability to regenerate itself is limited. SO the surgeons try a variety of ways to repair these defects. What specific methods are adopted should be based on the pathological types of cartilage defect in order to develop optimal strategies.

OBJECTIVE To analyze the major reasons of wound infection after external fixator application and then introduce management measures to prevent following wound infections. METHODS Totally 542 patients adopting external fixators between May 2005 and May 2007 were retrospectively reviewed. All the external fixator-related infections were inspected and the excretions from these infected wounds were collected to perform bacterial culturing. RESULTS The total infection rate of these 542 patients after external fixator application was 2.77%. Among them, six were infected with the bacteria in distraction osteogenesis group and the infection rate was 8.82%; three were infected in bone un-union and bone defect group and the infection rate was 5.36%; whilest the common fracture-fixing group got the lowest infection rate of 0.39%. CONCLUSIONS Wire-crossing positions are the most frequently infected sites after external fixation and the drug-resisted bacteria are the most commonly detected pathogens. Thus, increasing the stability of fixators, enhancing the infection supervision of operation environment, draining the wound thoroughly and using antibiotics rationally are the most effective managing measures to prevent external fixator-related infections in orthopedics.
