[Clinical and neurophysiological features of 700 patients with diabetic peripheral neuropathy].
To study the clinical and electrophysiological features of diabetic peripheral neuropathy in 700 patients to elucidate the relationships between them and evaluate the value of electromyography in the diagnosis of diabetic peripheral neuropathy. ⋯ The most common clinical and electrophysiological manifestation of diabetic neuropathy is sensory disturbance, which is more severe in lower limbs. The electrophysiological changes are not always accordant with clinical manifestations. Subclinical diabetic peripheral neuropathy can be detected by electrophysiological tests, which are useful to verify the range and extent of the nerve lesion involved in the early stage of diabetic peripheral neuropathy. Needle EMG is not recommended for screening diabetic neuropathy.

[How to choose the duration of prone-position ventilation in patients with acute respiratory distress syndrome caused by pulmonary or extrapulmonary diseases?].
To determine the different effect of prone-position ventilation (PPV) in patients with acute respiratory distress syndrome (ARDS) resulting from a pulmonary cause (ARDSp) and that from an extrapulmonary cause (ARDSexp) on oxygenation, respiratory mechanics and hemodynamics. To determine an appropriate duration of ventilation in the prone position in the two groups. ⋯ PPV could be used to improve severe hypoxemia of ARDS. It improved the PaO(2)/FiO(2) ratio rapidly in ARDSexp, but in ARDSp the improvement took a longer time.

[The changes in effective local blood perfusion and compensatory ventilation in different lung areas of acute respiratory distress syndrome rabbits model].
To discuss the mechanism of severe hypoxemia that induced with acute respiratory distress syndrome (ARDS) by way of observing the effective local blood perfusion in different lung areas of ARDS rabbits. ⋯ We indicated that the one of the main mechanisms of severe hypoxemia in ARDS might be caught by the shunt between pulmonary artery and pulmonary vein just like physiological right to left shunt, which caused severe ventilation/perfusion disturbance. Both low tidal volume ventilation + PEEP and prone position + low tidal volume ventilation + PEEP had good effects on ameliorating local blood perfusion, and the effects of ventilation mode of prone position + low tidal volume ventilation +PEEP might be better.

[Continuous veno-venous hemofiltration in treatment of acute severe hyponatremia: a report of 6 cases].
To investigate the effect of continuous veno-venous hemofiltration (CVVH) in the treatment of acute severe hyponatremia. ⋯ CVVH is effective in the treatment of acute severe hyponatremia, and could be considered as a treatment option because of its slow and continuous nature. A low-sodium replacement solution should be prepared to minimize its sodium concentration difference from the serum concentration. We recommend that the serum sodium concentration be corrected at an average rate of (2.50 +/- 0.14) mmol.L(-1).h(-1) at 6 h, (1.2 +/- 0.1) mmol.L(-1).h(-1) at 24 h and (0.82 +/- 0.10) mmol.L(-1).h(-1) at 48 h.
