Comparative StudyDistribution of ventilation and hemodynamic effects of different ventilatory patterns.
To compare the influence of cardiac-pulmonary function on clinical acute respiratory failure patients using Proportional assist ventilation (PAV), Pressure support ventilation (PSV) and intermittent positive pressure ventilation (IPPV). Here, we also describe some our experience with the clinical use of PAV. ⋯ For clinical acute respiratory failure patients, compared with PSV and IPPV, PAV has lower airway pressure, less WOBp and less influence on hemodynamics.

Comparative StudyProportional assist ventilation: methodology and therapeutics on COPD patients compared with pressure support ventilation.
To investigate the impact of proportional assist ventilation (PAV) on tolerance and breathlessness in ventilated chronic obstructive pulmonary disease (COPD), and to describe the patient-ventilator interaction, hemodynamic state, breathing pattern and work of breath during PAV and pressure support ventilation (PSV). ⋯ PAV is a feasible method for supporting ventilator-dependent patients and was well tolerated. It can improve the breathing pattern and reduce inspiratory effort. At the same degree of respiratory muscle unloading, PAV can be implemented at much lower peak inspiratory pressure than PSV. It can also apply proportional pressure support according to the patients' ventilatory demand.

Comparative StudyA retrospective study of continuous renal replacement therapy versus intermittent hemodialysis in severe acute renal failure.
To investigate the efficacy of continuous renal replacement therapy (CRRT) versus intermittent hemodialysis (IHD) in patients with severe acute renal failure (ARF). ⋯ CRRT perhaps may be the best choice in the treatment of severe ARF patients, for it can offer several distinct advantages compared to IHD. These may contribute to improving the survival rate of ARF patients, particularly those that are critically ill patients.

Genotyping and preparation of the recombinant nucleocapsid protein antigen of hantavirus.
To identify new recombinant antigens with potential for diagnosis of hemorrhagic fever with renal syndrome (HFRS) and establish reverse transcription-polymerase chain reaction-restriction fragments length polymorphism (RT-PCR-RFLP) for genotyping of hantavirus. ⋯ The good working titrer of expressed recombinant antigen showed that it has the potential to replace the natural antigen for detecting hantavirus antibodies. On comparison with cELISA, the detection rates for these two methods were 100% and 84.6%, and the coincidence rate was 84.6%. The former had a 15.4% higher sensitivity than the latter. The typing efficiency of RT-PCR-RFLP and sero-typing method was 85% (17/20) and 55% (11/20), respectively, showing that the former was 30% higher than the latter, while their results were highly consistent.

Immune privilege induced by cotransplantation of islet and allogeneic testicular cells.
To induce islet allograft long-term survival through cotransplantation of islet cells with sertoli cells. ⋯ Cotransplantation of islets with FasL+ sertoli cells induces local immune privilege and allows long-term graft survival without systemic immunosuppression.
