Objective To evaluate the effects of dead space fraction （VD/VT） on prone position ventilation （PPV） in patients with severe acute respiratory distress syndrome （ARDS） . Methods A total of 30 patients with severe ARDS （PaO2/FiO2< 100 mmHg） were enrolled in this study and were divided into pulmonary insult ARDS group （ARDSp） and extrapulmonary insult ARDS group （ARDSexp） according to different etiological factors. PaO2/FiO2 and VD/VT were recorded in supine position and prone position at 2 h，4 h，6 h，8 h and 10 h after ventilation . Results VD/VT decreased and PaO2/FiO2 increased with PPV. PaO2/FiO2 and VD/VT showed significant difference at different time points （P < 0.001），with the biggest change of VD/VT at PPV 4 h and the best transformation of PaO2/FiO2 （increase of PaO2/FiO2 >20 mmHg） after PPV 6 h. There was a positive correlation between VD/VT and PaO2/FiO2 by Pearson correlation analysis （t＝0.67，P < 0.001） . In ARDSp group，there was no significant change of PaO2/FiO2 and VD/VT between supine position and PPV 2 h. At PPV 4 h， PaO2/FiO2 significantly increased （t＝2.37，P＝0.03） and VD/VT significantly decreased （t＝5.26， P＝0.001） . No significant difference was found in PaO2/FiO2 and VD/VT at PPV 4 h to PPV 6 h. In ARDSexp group，PaO2/FiO2 significantly increased （t＝4.65，P＝0.04） and VD/VT significantly decreased （t＝3.56，P＝0.009） at PPV 2 h. There was no significant change from PPV 2 h to PPV 4 h. PaO2/FiO2 and VD/VT remained at the same level at PPV 6 h. Conclusion VD/VT can be used as an effective index to evaluate the efficacy of PPV in patients with ARDS and is more sensitive than PaO2/FiO2， so it can be used to guide the treatment of patients with pulmonary and extrapulmonary ARDS.

Currently, tenofovir is the first-line drug for the treatment of chronic hepatitis B. This article reviews the research advances in its therapeutic effects in patients who are resistant to lamivudine and adefovir dipivoxil, respond poorly to entecavir, or have multidrug resistance and introduces the results of the comparative study on the therapeutic effects of tenofovir monotherapy and combined treatment. It is pointed out that tenofovir has good safety and a good therapeutic effect in patients with drug resistance, including pregnant women; however, there are no significant differences in study results between tenofovir monotherapy and combined treatment.
