Objective To research the applicable ways on training and examination of defibrillator utilization in grassroots units. Methods The use of the "three-step training and two-part examination" mode, that is, three-step training(theoretical instruction, grouped practice and animal experiment), a total of 83 medical officers from inferior troops of PLA were trained for the use of defibrillators, and through passing two-part test(written test and skill test), the trainees were subsequently examined so that the efficacy of the training could be evaluated. Results The trainees can be acquired satisfying achievement in the two-part test after having passed the three-step training. The respectively average scores were 86.7 ?15.9 (written test) and 90.1?14.8 (skill test). Conclusion The "three-step training and two-part test" mode is a successful defib- rillators' training mode for inferior troops.

The systemic anaphylaxis murine model was induced by the injection of oval albumin (OVA)in aluminum hydroxide gel adjuvant. The death rate varied with the mouse species: 40-90% in Swiss and 69% in average,no death in C57BL/6 and 615 but some symptoms. developed. Swiss mice was adopted in this experiment.90% of mice pretreated with Lx remained living after allergen challenge,but only 20% in normal control. For elucidation the possible mechanism of Lx action,the study was carried out on detection of anti-OVA IgE specific antibody and histamin concentration in lung tissues. Passive cutaneous anaphylaxis(PCA)titers for anti-OVA IgE antibody in serum ranged from undilution to 160 in control group and not detectable in group pretreated with Lx. In addition, after absorption of PCA positive sera with anti-IgG antibody.the PCA activity was not affected. Histamin content was 1.54?0.24?g/ml in Lx treated mice caopared to 2.69?0.67?g/ml in control group(p

Objective Establish rabbit VX2 soft tissue tumor model,and treat it with percutaneous ethanol injection(PEI)under the guidance of magnetic resonance imaging.Make ready for the therapeutic evaluation with functional magnetic resonance imaging. Methods Fifteen healthy New Zealand white rabbits were included in this study.0.2 mL tumor tissue suspensions were injected into the rabbits’posterior limb.14 days later,all rabbits were underwent conventional MRI examination.PET were performed to all the tumors under the guidance of MRI in the next day of the examination.T2 WI was used as guidance and monitoring means.MR com-patible puncture needle with lateral hole was stabed into the lesion center,and inj ected anhydrous ethanol according to the volume of tumors’diameter (1 mL/cm )slowly.the tumors signal characteristics,morphological feature and pathological feature were ob-served pre and post-operation.Results All of the 1 5 rabbits were established soft tissue tumor model successfully;the success rate is 100%.The tumors were oval or round,3-4 cm in diam.MRI scanning showed low signal on T1 WI and high signal on T2 WI be-fore PEI.PEI was performed to all the tumors under the guidance of MR successfully with 3.5 mL ethanol injected into the tumors in average.T2 WI could monitor the ethanol in dispersion and distribution within the tumors clearly.Histologically,tumors were composed of large,uniform,oval/round cells arranged in solid nests which was intensive in the periphery of tumors.Necrosis tissue was apparent in the center of the tumors.10 days after operation,most tissue in the periphery of tumors was coagulative necrosis , only a few tumor cells left.Ranges of necrosis in the tumors center were obviously increased compared with pre-operation.Conclusion Rabbit VX2 tumor of soft tissue model is suitable for the therapeutic evaluation of tumor .It is an animal model which has the characteristic of simple to operate and high rate of suc-cessful.MR T2 WI can monitor the ethanol in dispersion and distribution within the tumors clearly.It is a good guidance and monitoring imaging method of tumor ablation.

The compatibility of traditional Chinese medicines (TCMs) formulae containing enormous information, is a complex component system. Applications of mathematical statistics methods on the compatibility researches of traditional Chinese medicines formulae have great significance for promoting the modernization of traditional Chinese medicines and improving clinical efficacies and optimizations of formulae. As a tool for quantitative analysis, data inference and exploring inherent rules of substances, the mathematical statistics method can be used to reveal the working mechanisms of the compatibility of traditional Chinese medicines formulae in qualitatively and quantitatively. By reviewing studies based on the applications of mathematical statistics methods, this paper were summarized from perspective of dosages optimization, efficacies and changes of chemical components as well as the rules of incompatibility and contraindication of formulae, will provide the references for further studying and revealing the working mechanisms and the connotations of traditional Chinese medicines.

Objective To construct an eukaryotic expression vector with human adipose most abundant gene transcript 1 (APM1) gene,and to investigate the transfection and expression of pCDEF-APM1 eukaryotic expression plasmid in HEK293 cells.Methods pCDEF-APM1 eukaryotic expression plasmid was constructed by DNA recombinant method.Expression vector pCDEF-APM1 was transfected into HEK293 cells with Effectene reagent.The level of human adiponectin protein in the supernatant of cell culture media was detected with double antibody sandwich ELISA.Results The sequence of DNA fragment from constructed pCDEF-APM1 plasmid was identical to that published in GenBank.There was raised human adiponectin protein level in culture supernatant of HEK293 cells tnmsfected with pCDEF-APM1.Conclusion The pCDEF-APM1,an eukaryotic expression plasmid for APM1 gene is successfully constructed.High protein expression of adiponectin can be obtained in HEK293 cells transfected with pCDEF-APM1 eukaryotic expression plasmid.

Objective To measure the effect of one-stage transplantation of reverse-flow vascular pedicle fibular grafts in treatment of infected nonunion of the distal tibia.Methods From January 2001 to December 2012,23 patients sustaining the infected nonunion of the distal tibia were transplanted with reverse-flow vascular pedicled fibular grafts in one-stage.There were 13 males and 10 females,aged 26 to 59 years (mean,38.7 years).Tibial nounion based on the Jain-Sinha classification was rated as Type A in 6 patients and Type B in 17 patients.After the operation,the patients received 2-3 weeks of intravenous antibiotic treatment and then 4-week oral antibiotic therapy.Wound healing,limb and ankle joint fucntion and outcomes in fibular transplantation were observed.Results Duration of follow-up was 16-46 months (mean,28.6 months).There were no exudates and ulcerations of the skins.Smooth healing was achieved in all the patients except that fibular fracture was noted in one patient healed after cast immobilization.Healing time ranged from 12 to 28 weeks (mean,15.6 weeks).Limb function evaluated with Ennecking system had (87 ± 11) ％ restoration.According the Olerud-Molander scoring system,ankle function was excellent in 16 patients and good in 7 patients,with the excellent-good rate of 100％.Conclusion One-stage reverse-flow vascular pedicle fibular grafting is an optional procedure for treatment of infected nonunion of the distal tibia,due to the technique is easy and effective.

objective To observe the distribution of vitamin D receptor(VDR)gene polymorphisms in children of Han nationality and investigate the relationship between VDR gene polymorphisms and the susceptibility to children's dental fluorosis of Han nationality.Methods From October of 2008 to March of 2009,a case-control study was conducted among children between 8 and 12 years old with(n=101)and without(n=102)dental fluorosis using Dean method in Guandian countyside of Fengtai county in Anhui province.DNA was extracted from blood samples ofthese children.The Apa I,Bsm I,Fok I and raq I polymorphisms in the VDR gene were genotyped using polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).The distribution of the genotypes in patients and the control group were analyzed.
