Comparative Study Controlled Clinical Trial
Intravenous alfacalcidol once versus twice or thrice weekly in hemodialysis patients.
Secondary hyperparathyroidism remains a serious problem in hemodialysis patients. The use of vitamin D analogs still constitutes a basis for its treatment. This study was carried out to evaluate the efficacy of intravenous administration of alfacalcidol once versus twice or thrice weekly in hemodialysis patients with secondary hyperparathyroidism. ⋯ Although the phosphorus level increased from 1.56 ± 0.36 mmol/L (mean ± SD) in stage 1 to 1.70 ± 0.46 mmol/ L in stage 2 (P = 0.003), and calcium-phosphorus product increased from 3.48 ± 0.82 mmol(2)/L(2) (mean ± SD) in stage 1 to 3.76 ± 1.00 mmol(2) /L(2) in stage 2 (P = 0.017), they remained in the target levels recommended by the Kidney Disease Outcomes Quality Initiative guidelines. No serious effects were observed during stage 1 and stage 2, respectively. Intravenous alfacalcidol once weekly is effective, safe and less costly in suppressing intact parathyroid hormone compared to twice or thrice weekly administration in chronic hemodialysis patients.

Randomized Controlled Trial Comparative Study
Clinical effects of pulse high-volume hemofiltration on severe acute pancreatitis complicated with multiple organ dysfunction syndrome.
To evaluate the effects of pulse high-volume hemofiltration (PHVHF) on severe acute pancreatitis (SAP) with multiple organ dysfunction syndrome (MODS). Thirty patients were divided into two groups: PHVHF group and continuous venovenous hemofiltration (CVVH) group. They were evaluated in terms of clinical symptoms, acute physiology and chronic health evaluation (APACHE) II score, sequential organ failure assessment (SOFA) score, simplified acute physiology (SAPS) II score and biochemical changes. ⋯ The doses of dopamine for shock patients were also decreased in the two groups (P < 0.05), with more reduction in the PHVHF group than the CVVH group (P < 0.05). The levels of IL-6, IL-10 and TNF-α decreased (P < 0.05) in the PHVHF group more significantly than the CVVH group (P < 0.01). PHVHF appears to be superior to CVVH in the treatment of SAP with MODS.

Comparative Study
Role of different replacement fluids during extracorporeal treatment in a pig model of sepsis.
In an extracorporeal combination therapy, the impact of different replacement fluids on survival was tested in a bacterial sepsis model in pigs. In an animal study 19 pigs, weighing 7.5-11.1 kg, were included. All groups received an intravenous lethal dose of live Staphylococcus aureus over 1 h. ⋯ All animals of the group P100 survived, while all animals of group P0 and five out of seven animals of the P30 group died during the observation time. Extracorporeal therapy consisting of online centrifugation and plasma filtration with 100% pig plasma as replacement fluid significantly improved survival in a pig model of sepsis. Further studies with this approach are encouraged.
