Cerebral edema and elevated intracranial pressure (ICP) are common complications observed following ischemic stroke. Osmotherapy has been used as a foundation to manage ICP induced by cerebral edema, and albumin is one of the most commonly used osmotic agents. The present study aimed to explore whether albumin lowered ICP by reducing cerebral edema when albumin elevated the colloid osmotic pressure (COP) of plasma.

The purpose of this paper is to explore the correlation between DND1 expression levels and clinical characteristics in prostate cancer (PCa) patients.
Materials And Methods: To assess the expression of DND1 in tumor specimens compared with paired paracancerous tissues, the sample from 83 patients was analyzed by immunohistochemistry.
Background/aims: miR-146a has recently been shown to promote cell proliferation, migration, and invasion in many cancers, but the role of miR-146a in clear cell renal cell carcinoma (ccRCC) remains unclear.
Methods: Reverse transcription quantitative PCR (RT-qPCR) was performed to investigate the mRNA expression of miR-146a and CADM2 in ccRCC tissues. The luciferase reporter assay, Western blotting, and ChIP assay were carried out to explore the promoter and the transcription factor of miR-146a.
Zwitterionic poly(sulfobetaine acrylamide) (pSBAA)-based nanocomposite hydrogels impregnated with germicidal silver nanoparticles (AgNPs) were synthesized and implemented for the treatment of infected chronic wounds. The zwitterionic hydrogels exhibited excellent non-sticky properties and had reinforced mechanical properties by the addition of hectorite nanoclay and poly(ethylene glycol)dimethacrylate as physical and chemical crosslinkers, respectively. In addition, AgNPs were grown within the intercalated clay/polymer structure by in situ free radical reduction, as confirmed by UV-vis spectroscopy and transmission electron microscopy (TEM).

Lyophilization, packing, and terminal sterilization with gamma-ray can facilitate the application of cadaveric split-thickness skin grafts, but may alter the adhesion properties of the grafts. In a pilot study, we found that 500 Gy γ-irradiation seemed not to reduce the adherence between the grafts and wound beds.

Biosynthetic artificial skin is an alternative for critical wound coverage. We designed a new artificial skin bilayer to close difficult wounds permanently.

The hydrogels exhibited reinforced mechanical properties from added hectorite nanoclay as a physical crosslinker in the polymer chains. Due to the strong interaction with water molecules via ionic solvation, the hydration of the zwitterionic nanocomposite hydrogels was superior to the non-ionic 2-hydroxyethyl methacrylate (pHEMA) hydrogels, which interacts with water molecules via hydrogen bonding.

We have a modified method to create a safe finger tourniquet for short duration finger surgeries, which can avoid such tragedy.

Objective: This study was designed to assess the long-term efficacy of microscopic excision of subungual glomus tumors.
Purpose: Surgical reconstruction of trochanteric sores remains a formidable task for plastic surgeons. Diverse types of flaps have been proposed for use in this situation, each with particular advantages and limitations. This study aimed to compare the surgical outcomes between the hatchet-shaped tensor fascia lata (TFL) flap and the pedicle anterior lateral thigh (ALT) flap in treatment of trochanteric sores.

Materials include liquid silicone, paraffin, polyacrylamide hydrogels, and unknown gels. They usually cause granulomatous reactions, erythema, pain, and even skin necrosis.

The aim of this study was to analyze the surgical approaches to the treatment of gynecomastia and their outcomes over a 10-year period.

We presented a special case of primary anterior mediastinal tumor with both prominent cystic change and extreme high carbohydrate antigen 19-9 level of cystic fluid here. From the finding of this case report, we suggested that the diagnosis of cystic anterior mediastinal tumors should include both cystic seminoma and mature cystic teratoma.

Objective: To evaluate the feasibility of using the dual stylet method as a bedside measure after unsuccessful of the spiral distal end nasal-enteral feeding tubes into the duodenum in critically ill patients.
Methods: Spiral distal end nasal-enteral feeding tubes were introduced into the stomach of 50 critically ill patients but unable to pass through the pylorus from July 2005 to March 2007. Under electrocardiographic monitoring, the dual stylet method was used as a bedside measure to facilitate the passage.
