Iron plays vital roles in many life activities and it is strictly controlled via elaborate metabolic system. Growing evidence has suggested that the dysfunctional iron homeostasis is implicated to many refractory diseases including cancers and neurodegenerations. Systemic and cellular iron are regulated through different pathways but are meanwhile interconnecting with each other via a few key regulators, whose abnormal expressions are often found to be the root causes of many iron disorders. Nano-sensing techniques have enabled the detection and monitoring of such central players, which provide rich information for the iron homeostasis profile through multiplexing and flexible designs. In addition to general sensing, nanoprobes are capable of target imaging and precise local access, which are particularly beneficial for revealing the conditions of intra-/extracellular environments. Nanomaterials have also been applied in some therapies, targeting the aberrant iron metabolism. Various iron uptake pathways have been utilized for target drug delivery and iron level manipulation, while abnormal iron content is notably useful in tumor killing. With brief introduction to the significance of iron homeostasis, this review includes recent works regarding the nanotechnology that has been applied in iron-related diagnostic and therapeutic applications.

We developed a cell-free, resorbable graft intended to remodel in situ into a living vessel. The graft consisted of a soft electrospun poly(glycerol sebacate) (PGS) core, a PGS prepolymer (pPGS) coating, and a reinforcing electrospun poly(ε-caprolactone) (PCL) sheath. The core contained 4.37 ± 1.95 μm fibers and had a porosity of 66.4 ± 3.2%, giving it large pores to encourage cellular infiltration and pro-healing macrophages. The sheath contained 6.63 ± 0.89 μm fibers and had a porosity of 80.5 ± 2.1%. in vitro testing suggested that the stress achieved at arterial pressure would be 13-fold lower than the yield stress of the graft. Grafts were implanted as 7 cm carotid interpositions in two sheep. Sheep were maintained on dual antiplatelet therapy and followed with duplex ultrasound. One graft ruptured at 13 days. The second animal was euthanized with a dilated graft at 15 days. Histology showed near-total degradation of the core and a robust inflammatory response within the sheath. Little neotissue had formed within the graft wall or lumen, but the graft had become surrounded by fibroblast-rich and vascularized connective tissue. Because PCL is commonly used in resorbable grafts, this mechanical destabilization was unexpected. We speculate that the inflammatory response instigated by the rapidly degrading PGS intensified degradation of the PCL and that the large pores enabled a prolonged acute host-graft reaction which attacked the entire bulk of the material, speeding weakening. Future work will focus on how to moderate inflammation and improve remodeling of grafts in large animals.
This study was performed to observe the effect of internal Balser plate fixation for treating unstable sternoclavicular joints (SCJ) and displaced medial clavicle fractures.

From April 2009 to September 2016, 17 consecutive patients who underwent open reduction and internal Balser plate fixation for SCJ dislocations or medial clavicle fractures were retrospectively reviewed. There were 11 male and six female patients, with a mean age of 45.6 ± 15.5 years. Standardized treatment procedures consisted of reduction, creating a space posterior dorsal osteal face of the sternal manubrium, an inverted Balser plating, and postoperative immobilization. At follow-up, plain radiographs were assessed for fracture union, implant loosening, degenerative changes, and joint congruity. Clinical evaluation included completion of the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire; determination of the Constant and Murley score and visual analog scale (VAS) score; and assessment of intraoperative and postoper medial clavicle fractures can be treated successfully with Balser plate fixation. This technique permits early functional exercise while preserving the SCJ.Immune checkpoint inhibitors (ICIs) activate host antitumor immunity to kill tumor cells. However, ICI therapy may be accompanied by a series of immunotherapy-related adverse effects (irAEs) caused by activated autoreactive T cells. Glucocorticoids are the mainstream therapy for irAEs. Olaparib However, the usage, dosage and course of treatment of irAEs with glucocorticoids differs from those used in classic autoimmune diseases. Furthermore, the long-term use of large doses of glucocorticoids may cause serious adverse effects. In this article, the mechanism, dosage forms, adverse effects and management of glucocorticoids are described in detail, providing references and suggestions for oncologists to use glucocorticoids in the treatment of irAEs.
To evaluate the efficacy of the electromagnetic distal targeting system in the treatment of humeral shaft fractures.

From January 2012 to December 2018, we retrospectively reviewed 60 patients with humeral shaft fractures treated by intramedullary nailing. Among 60 cases, 41 were men and 19 were women. The average age at surgery was 48.5 years (range, 21-81 years). We performed the same surgical procedure for all patients. According to the different distal locking technique used, all patients were divided into two groups. The standard fluoroscopic freehand technique was used for Group FH, while the electromagnetic real-time targeting technique was used for Group EM. All procedures were performed by two senior surgeons. Overall surgical time, cases of complications, failure of distal locking, union time, and shoulder function assessment were recorded intraoperatively and during follow-up.

Twenty-seven patients in Group FH and 33 patients in Group EM met the inclusion criteria. No significant difference was found in the demographic data of the two groups.
