PURPOSE Bovine milk exosomes, which are enriched with microRNAs (miRNAs) and proteins, regulate immune response and growth. In the present study, we aimed to assess the protective effects of bovine milk exosomes against oxidative stress of intestinal crypt epithelial cells (IEC-6). METHODS Bovine milk exosomes were isolated and characterized. To assess the protective effects of exosomes, IEC-6 cells were pretreated with exosomes, followed by H2O2. Cell viability and levels of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GPX), reactive oxidative species (ROS), and lactate dehydrogenase (LDH) were measured. The expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (Ho1) genes, and miR-146a, miR-155, and the HO-1 protein were also determined. RESULTS The isolated bovine milk exosome were positive for CD63 and CD9 expression. The exosomes were approximately circular and had a diameter of about 67.23 nm. Pretreatment of IEC-6 cells with bovine milk exosomes enhanced cell viability; increased SOD and GPX activities; and reduced LDH, ROS, and MDA levels after H2O2 challenge. Further analysis showed that exosome pretreatment increased intracellular miR-146a and miR-155 levels. Exosome pretreatment inhibited the elevation of Nrf2 and Ho1 gene expression induced by H2O2, but promoted HO-1 protein expression. CONCLUSION The results indicated that bovine milk exosomes exerted protective effects against oxidative stress in IEC-6 cells.BACKGROUND As evidence-based medicine has taken hold across medical specialties, the level of evidence within the facial plastic surgery literature has risen, but remains weak in comparison. There has not yet been a systematic, critical appraisal of the relative strength of evidence among subsets of the practice of facial plastic surgery. METHODS The current study is a systematic review, designed to evaluate the level of evidence observed in the facial plastic surgery literature. Five journals were queried using facial plastic surgery terms for four selected years over a 10-year period. Following screening, articles were assigned to a category regarding subject matter, assessed for the presence of various methodological traits, and evaluated for overall level of evidence. Comparisons were made in regard to level of evidence across the breadth of facial plastic surgery subject matter. RESULTS A total of 826 articles were included for final review. Studies on operative facial rejuvenation and rhinoplasty had significantly fewer authors on average than studies on cancer reconstruction or craniofacial topics. Craniofacial studies demonstrated higher levels of evidence relative to all other categories, with the exception of facial paralysis and facial trauma studies, from which there was no significant difference. In general, reconstructive studies had significantly more authors and higher levels of evidence than did articles with an aesthetic focus. CONCLUSION Level of evidence in facial plastic surgery remains relatively weak overall. Reconstructive and particularly craniofacial studies demonstrate higher mean level of evidence, relative to other subsets of facial plastic surgery.

This study aimed to (1) define key components of the nasal airway, (2) identify frequent causes of nasal obstruction, and (3) review existing treatment methods. METHODS A systematic review of the literature was performed, and 135 studies were included via the following criteria English, human subjects, and a primary endpoint of nasal airway improvement. Exclusion criteria were abstract only, no airway data, pediatric patients, cleft rhinoplasty, sleep apnea, isolated traumatic nasal reconstruction, and cadaveric-only or animal studies. RESULTS The relevant obstructive sites include the ENV, septum, inferior turbinates, INV, and nasal bones. Addressing the alar rim alone may be insufficient, and inspection of the lateral wall and crura may be indicated. Correction of septal deviation involves attention to the bony base. Mucosal sparing treatment of inferior turbinates improves outcomes. INVs are a major source of nasal obstruction, and treatment includes spreader grafts. The bony nasal vault can contribute to nasal obstruction, including due to surgical osteotomies. CONCLUSIONS Anatomic causes of airway obstruction include the alar rims and lateral nasal walls, deviated nasal septum, inferior turbinate hypertrophy, decreased INV angle, and narrowed nasal bones. Treatments include graft placement; septoplasty; mucosal sparing turbinectomy; and lateral wall support. Pitfalls include failing to address the bony septum, over-resection of inferior turbinates, and narrowing of the nasal vault. Appreciation of airway management during rhinoplasty will improve functional outcomes. LEVEL OF EVIDENCE V This journal requires that authors assign a level of evidence to each article.

MATERIALS AND METHODS A total of 219 patients with 225 type IIIB open fractures of the tibia were studied prospectively between July 2016 and June 2017. The decision of salvage or amputation was taken by a combined consensus of senior orthopaedic and plastic surgeons, blinded to the scores. All four open injury scores were calculated by an independent reviewer following initial debridement. The follow-up period was one to two years. RESULTS After final follow-up, there were 193 (85.7%) successfully salvaged limbs, 19 primary amputations without attempt of debridement (8.4%), three primary delayed amputations within 72 hours (1.
