Sepsis is an infection induced systemic inflammatory response syndrome and is a major cause of morbidity as well as mortality in intensive care units. A growing body of evidence suggests that the activation of a proinflammatory cascade is responsible for the development of immune dysfunction, susceptibility to severe sepsis and septic shock. The present theories of sepsis as a dysregulated inflammatory response and immune function, as manifested by excessive release of inflammatory mediators such as high mobility group box 1 protein (HMGB1), are supported by increasing studies employing animal models and clinical observations of sepsis. ⋯ Here we review emerging evidence that support extracellular HMGB1 as a late mediator of septic complications, and discuss the therapeutic potential of several HMGB1-targeting agents in experimental sepsis. In addition, with the development of traditional Chinese medicine in recent years, it has been proven that traditional Chinese herbal materials and their extracts have remarkable effective in treating severe sepsis. In this review, we therefore provide some new concepts of HMGB1-targeted Chinese herbal therapies in sepsis.

Recent studies have shown that α2-adrenergic agonists can reduce postresuscitation myocardial injury. This study was undertaken to observe changes of hemodynamics, myocardial injury markers cTnT and cardiac morphology by establishing a cardiopulmonary resuscitation model with rabbits, and to detect whether α-methyl norepinephrine (α-MNE) can reduce the myocardial injury after CPR and improve cardiac function. ⋯ Methylnorepinephrine can lessen myocardial dysfunction after CPR.

The role of Inter-facility transport (IFT) of patients is an emerging specialty requiring service reorganization, diversion of major trauma to trauma center. This study aimed to determine the patients who are more prone to en route adverse event during the period of 22:00 to 07:00, based on critical in-patient needs provided by the Emergency Department (ED) nursing staff at Alice Ho Miu Ling Nethersole Hospital (AHNH). ⋯ A specialized transport team from the ED can assist other clinical departments by providing expert care during IFT. In spite of the high quality of care, adverse events do commonly occur.

With the development of internal fixation materials, simple operation with internal fixation has become a tendency. Ni-Ti shape memory alloy embracing fixator has such advantages as slight injury, easy operation, security, reliable fixation, and better histocompatibility. The present study was to explore curative effect and postoperative results of Ti-Ni shape memory alloy embracing fixator in patients with multiple fractured ribs and flail chest. ⋯ It is practical to perform an operation for fracture of multiple ribs using a Ti-Ni shape memory alloy embracing fixator. The fixator, which is less traumatic, simple, safe, and reliable, has a good-histocompatibility and fewer postoperative complications.

Uncontrolled hemorrhage is responsible for over 50% of all trauma-related deaths within the first 48 hours after admission. Clinical observations together with recent research resulted in an appreciation of the central role of coagulopathy in acute trauma care. A synopsis is presented of different retrospective analyses based upon datasets from severe multiply injured patients derived from the TR-DGU database (Trauma Registry of the Deutsche Gesellschaft fur Unfallchirurgie (DGU)/ German Society of Trauma Surgery) with respect to frequency, risk stratification and therapeutic options of acute traumatic coagulopathy (ATC). ⋯ An early aggressive management of ATC including a more balanced administration of blood products to improve outcome is advocated.
