Randomized Controlled Trial
Safety of recombinant human granulocyte-macrophage colony-stimulating factor in healing pediatric severe burns.
We explored the safety of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) for healing burns in children. Subjects were randomly assigned to two groups: the experimental group received external rhGM-CSF gel, and the control group received rhGM-CSF gel matrix components, applied to the burn surface. Neither group was given any other drugs that promote wound healing. ⋯ There were no obvious adverse reactions. There was no significant difference between the blood routine, urine routine, and liver and kidney function in the two groups before the treatment and after 3 days (P > 0.05). Compared with saline treatment of severe burns, rhGM-CSF can effectively shorten the healing time without significant adverse reactions, and is an effective and safe treatment for burns in children.

Central venous blood oxygen saturation (ScvO2) is an important monitoring index of fluid resuscitation. However, monitoring of ScvO2 is not continuous and invasive. Near infrared spectroscopy (NIRS) is an optical technology for the noninvasive detection of hemodynamic changes, with advantages of being real-time, continuous, low-cost, and portable. ⋯ Results were as follows: 100% of monitored points fell within the range of the mean ± 1.96 SD of the difference between the StO2 and ScvO2; range of the mean ± 1.96 SD of the difference between the StO2 and ScvO2 was 3 ± 10.2; confidence interval of the difference between the StO2 and ScvO2 was -7.2 to 13.2%. The StO2 monitored with NIRS correlated highly with the ScvO2 measured in the internal jugular vein. Therefore, the StO2 can be used for directing clinical treatment with further research.

The aim of this study was to determine the effect of etomidate and propofol pretreatment on the expression of glucocorticoid receptor and the prognosis of sepsis. The sepsis rat was used as a model. During glucocorticoid treatment, etomidate and propofol were applied alone or together at different time points. ⋯ Etomidate was best used immediately after modeling, whereas propofol was most suitable for use during the peak inflammatory reaction. These results demonstrated that anesthetics had the ability to enhance the effect of glucocorticoids in the treatment of sepsis. Etomidate was indicated for use in the early stage of inflammation to enhance expression of the glucocorticoid receptor, while propofol application was indicated at the peak of the inflammatory reaction owing to its strong anti-inflammation effect.

To study the role of boswellic acid in reducing asthma phenotype severity and the relationship between the expression of pSTAT6 and GATA3, thirty-six mice were randomly divided into normal control group, asthma group, and boswellic acid group (treatment group). The asthma model was established through an intraperitoneal injection of sensitization liquid (0.15 mL aluminum hydroxide gel at 88.67 mg/mL and 0.05 mg ovalbumin). pSTAT6 and GATA3 expression levels in peripheral blood were detected by reverse transcription-polymerase chain reaction and Western blot analysis. pSTAT6 and GATA3 gene expressions in the asthmatic group were significantly higher than in the normal control group; they were markedly lower in the treatment group than the asthma group, and there was no significant difference when compared with the normal control group. ⋯ GATA3 expression had a positive correlation with pSTAT6 expression. Boswellic acid may improve asthma symptoms by inhibiting pSTAT6 expression, which consequently reduces GATA3 expression.

Trigeminal neuralgia is a sudden, severe condition characterized by stabbing and recurrent pain. Radiofrequency thermocoagulation (RFT) and pulsed radiofrequency (PRF) are common surgical interventions used to treat trigeminal neuralgia. This study aimed to investigate the therapeutic effects and associated complications of a combination of RFT and PRF in the treatment of trigeminal neuralgia. ⋯ Data showed that facial numbness and postoperative masticatory muscle weakness recovered more rapidly in patients receiving combined RFT and PRF treatment. Decreased corneal reflex was relieved to a significantly greater extent in groups receiving PRF than those without. Thus, compared to the use of RFT at 75°C alone, the combination of PRF and RFT helped eliminate postoperative complications, such as facial numbness, masticatory muscle weakness, and decreased corneal reflex, indicating that it could be useful for surgically treating trigeminal neuralgia.
