Decoy receptor 3 (DcR3), a member of the tumor necrosis factor receptor superfamily, is amplified and over-expressed in various cancers. The objective of the present study was to investigate the concentration of DcR3 in sera of hepatocellular carcinoma (HCC) patients and its clinical significance. ⋯ The high serum concentration of DcR3 might play a certain role in pathogenesis, progress, and metastasis of HCC. Moreover, DcR3 might serve as a valuable molecular indicator in early diagnosis and contribute to predicting the clinical outcome in HCC patients.

Traumatic brain injury makes the brain vulnerable to secondary insults. Post-traumatic alterations in intracranial dynamics, such as reduced intracranial compliance (IC), are thought to further potentiate the effects of secondary insults. Reduced IC combined with intracranial volume insults leads to metabolic disturbances in a rat model. The aim of the present study was to discern whether a post-traumatic hypotensive insult in combination with reduced IC caused more pronounced secondary metabolic disturbances in the injured rat brain. ⋯ In conclusion, reduced IC did not increase the metabolic disturbances caused by the post-traumatic hypotensive insult. The results suggest that a mild to moderate hypotensive insult after initial post-traumatic resuscitation may be tolerated better than an early insult before resuscitation.

The aim of this research was to create a laboratory instrument for the estimation of post-transplant lymphocele origin. It is based on the enzymatic activity of creatine kinase (CK) in the lymphocele content. ⋯ Significantly different CK enzyme activity was observed in different regions of the retroperitoneum. The presented graph is a simple instrument for the estimation of the lymphocele content origin. The method requires percutaneous aspiration of the lymphocele and evaluation of the CK and GGT activity in the sample. From the graph the estimated proportion of renal lymph in the lymphocele can be read directly. This instrument can provide better understanding of post-transplant lymphocele fluid source.

Approximately 90% of colorectal cancer (CRC) deaths arise from the metastatic dissemination of primary tumors. It is difficult to predict metastasis of colorectal cancer, especially for patients with the same pathological subtype and differentiation. AIMS. To identify biomarkers for predicting CRC metastasis. ⋯ Our data suggest that PTCH1 might be a potential biomarker that could discriminate CRC with high from that with low metastatic risk.

Randomized Controlled Trial
Effects of different priming doses of propofol on fentanyl-induced cough during anesthesia induction: a preliminary randomized controlled study.
Fentanyl-induced cough is not an uncommon condition during the induction of general anesthesia. A preliminary randomized controlled study was designed to observe the effects of different priming doses of propofol on fentanyl-induced cough during anesthesia induction. A total of 120 patients were randomized into 4 groups (n = 30) to receive the intravenous injection of intralipid (group I), propofol 1 mg.kg(-1) (group II), propofol 1.5 mg.kg(-1) (group III), or propofol 2 mg.kg(-1) (group IV) 1 minute before a bolus of fentanyl 2.5 microg.kg(-1). ⋯ Groups III and IV had a lower incidence and less severity of cough than group II (P < 0.05). In summary, a priming dose of more than 1 mg.kg(-1) of propofol is effective to suppress fentanyl-induced cough in a dose-dependent manner. We suggest using a priming dose of propofol 1.5 mg.kg(-1) to suppress cough during the anesthesia induction with propofol and fentanyl in clinical practice.
