Cardiological nuclear medicine was divided into two parts: diagnosis in vivo and diagnosis in vitro. Diagnosis in vivo need to put radioactive agents into patients, through dynamic and metabolic processes of radioactive agents and by using outside-body devices to gain parameters and images which reflect the physical and functional condition of heart, heart valves and blood supply of coronary arteries. Diagnosis in vitro does not put radioactive agents into patients. It used radioimmunoassays and immunoradiometricassays. Using patients’ blood samples, they quantify some agents with low concentration in blood. These are uninvasive tests with high accuracy that useful in diagnosis, treatment and prognosis of various diseases.

Objective:To test the ventilator system calibration error, and analyze the effects of mechanical ventilation parameters and the related safety.Methods: Based on the system calibration principle of ventilator, the mechanical ventilation performance of the ventilator with calibration error was tested by the gas analyzer and the correlation of mechanical ventilation parameters and the system calibration error was analyzed.Results:The pressure drop value and a lower compliance can affect the tidal volume, the mean airway pressure and the peep values. Conclusion: The system calibration is important before operating mechanical ventilation. It can make safe, accurate and efficient in mechanical ventilation with controlling the system calibration error in a limited range.

Based on introducing the conception and developing status of the telemedicine and current administrative guidance documents of telemedicine,the paper sorts out legal relations among all parties by combining the developing status of all parties,and defines the involved civil liabilities,in order to lay a foundation for China to improve the telemedicine system standard,and vigorously promote the application of telemedicine.

For over twenty years, the Insitute of Immunopathology of Xi'an Medical University, the antecedent Institute of Cancer Research, has long been engaged in the study on tumor immunity. Beginning with the exploration of the mechanisims for the activation of tumor-infiltrating lymphocytes(TIL) and tumor evasion till translating the relevant achievements into tumor immunotherapy and immunoprevention. From one facet, all the facts reflect the arduous course of the struggle of human beings for conquering cancer.

Objective: To investigate the inhibitory effects of Curcumin on A? generation in vitro and explore its potential mechanisms involing BACE1 and PPAR?.Methods: Plasmids APPswe and BACE1-mychis were transiently co-transfected into SHSY5Y cells by LipofectaminTM2000,then treated with Curcumin at 0(control Group),1.25,5.0,20.0 ?mol/L for 24 hr,or with Curcumin at 5 ?mol/L for 0,12,24 and 48 hrs for the time course assay.RT-PCR was performed to measure the endogenous levels of BACE1 mRNA and PPAR?.Western blot were used to detect the protein expression of BACE1 and PPAR?.The major cleavage product——A?40 and A?42 was detected by ?-amyloid 1-40 or 42 Colorimetric ELISA assay.Results: The mRNA level and protein level of BACE1 were decreased obviously in a dose-and time-dependent manner after treated with Curcumin in the cell line(P

We have immunophenotyped the tumor-infiltrating mononuclear cells, especially the I_2 (HLA-DR) antigen and OKT_9 antigen expression on lymphocyte infiltrates to determine the activity of infiltrating T cells in 63 cases of advanced stomach and colon cancer. In addition, 18 specimens for biopsies from patients with chronic gastritis and colitis were used as controls. In most cancer specimens, the infiltrating T cells were defficient of I_2 antigen, only 10 out of 63 cases had about 10--30% I_2 positive infiltrating T cells, and nearly no OKT_9 positive infiltrating T lymphocytes. This finding is quite different from that in nomal mucosa and chronic inflammatory mucosa, with more I_2 positive lymphocytes in their infiltrates, indicating that the infiltrating T lymphocytes in tumor tissue inhibited by ome inhibitors present in their environment and contrabuting to the explanation why the tumor mmunity can not control the growth and spread of the tumor and lead to the elimination of the tumor.

Many studies demonstrate the existence of regulatory T(Treg)cell at tumot sites,implying that these Treg cells may induce local immune tolerance.Deep studies on the role of Treg cells in cancer patients will offer new approaches for tumor immunotherapy.

BACKGROUND: Traditionally, tendon was repaired by autoallergic tendon transplantation and transfusion; however, both methods were limited by supply region and additional trauma, and the development was slowed down.OBJECTIVE: To summarize biomechanical characteristics of seed cells, stent, and bioreactor during repairing tendon tissue defect, and provide prevention and cure of tendon injury induced by training and competition.METHODS: A computer-based online search was conducted in VIP database with the keywords of "movement training, tendon tissue, repair" from January 2004 to October 2009.Articles which were related to tendon tissue injury induced by movement training were included, but articles related to duplicated research or Meta analysis were excluded.RESULTS AND CONCLUSION: Tissue-engineered tendon has achieved therapeutic effects to a certain degree; however, it is still not used for clinical application.Source of seed cells was restrict to autoallergic tendon cells; on the other hand, comparison between fibroblast and tendon cells, gene chip was used to modify gene in order to solve source of seed cells of tissue-engineered tendon.During regeneration of tendon, normal mechanical stimulation played an important role in moulding of newborn tendon.Because the stimulation might induce orientation arrangement of newborn collagen fiber, enhance mechanical strength of newborn tendon, make sure the functional training as eady as possibly, effectively reduce tendon adhesion, and provide an ideal stent for great circulation of tendon repairing.Scientific training is necessary for coaches and athletes to avoid from tendon tissue injury during movement training and competition.Although tendon tissue engineering has developed well, it still brings adverse effect on body and mind.
