Effects of different doses in continuous veno-venous hemofiltration on plasma lactate in critically ill patients.
Many studies have shown that continuous renal replacement therapy (CRRT) could clean lactate and treat the hyper-lactatemia. On the contrary, some other studies found that filter lactate clearance only accounted for a very small part of total lactate clearance and the hemofilter's contribution to the overall lactate clearance was negligible. The objective of this study was to evaluate the effects of various doses of continuous veno-venous hemofiltration (CVVH) on plasma lactate elimination in critically ill patients. ⋯ Plasma lactate can be eliminated by CVVH and different doses of CVVH affect the rate of lactate clearance in critically ill patients.

Case ReportsComparisons in finite element analysis of minimally invasive, locking, and non-locking plates systems used in treating calcaneal fractures of Sanders type II and type III.
Calcaneal fractures are relatively common but complex, while the treatment of these fractures is still controversial. The objective of this study was to compare the biomechanical stability of minimally invasive, locking, and non-locking plating systems used for fixing Sanders type II and type III calcaneal fractures. Finite element analysis was used for comparing the three types of plating systems. This study helped in guiding the clinical management of calcaneal fractures. ⋯ The minimally invasive plating method could be a better alternative method in treating Sanders type II and type III calcaneal fractures. The observed stiffness of locking plate was not obviously stronger than unlocked plate.

Feasibility and value of quantitative dynamic contrast enhancement MR imaging in the evaluation of sinonasal tumors.
Quantitative dynamic contrast enhancement MR imaging (DCE-MRI), used to measure properties of tissue microvasculature and tumor angiogenesis, is a promising method for distinguishing benign and malignant tumors and characterizing tumor response to antiangiogenic treatment. The aim of this study was to assess the feasibility of quantitative parameters derived from clinically used DCE-MRI for distinguishing benign from malignant tumors in the sinonasal area, which may be potentially useful for prediction and monitoring of treatment response to chemoradiotherapy of sinonasal tumors. ⋯ It is feasible that quantitative parameters of tumors can be derived from clinically used DCE-MRI in the sinonasal region. Preliminary findings suggest an increased value for quantitative DCE-MRI in the evaluation of sinonasal tumors in clinical practice.

Decompression alone versus decompression with instrumented fusion for young patients with single-level lumbar disc herniation: a short-term prospective comparative study.
For young patients, the surgical method for lumbar disc herniation remains controversial. The aim of this study was to prospectively determine the short-term clinical outcome after surgery for young patients with lumbar disc herniation. ⋯ The short-term results of our study showed that both methods of surgery obtained effective clinical outcomes, but decompression alone had some advantages (shorter surgery time, less blood loss, shorter hospital stay, and lower cost) compared with decompression with instrumented fusion. Young patients with decompression alone could achieve great physical function earlier.

The brain death confirmation tests occupy a different position in each country's diagnostic criteria (or guideline); the choices of tests are also different. China brain death criteria include clinical judgment and confirmation tests. This study aimed to confirm the preferred confirmatory test and complementary confirmatory tests. ⋯ The completion rate of respiratory arrest provocation test remains a problem in the clinical diagnosis of brain death. If the test cannot be completed, whether to increase a confirmatory test is debatable. SEP had an ideal sensitivity, and the specificity will reach 100% after combining with TCD or EEG. When a confirmed test was uncertain, we suggest increasing another confirmatory test.
