Abstract
Adverse skin reactions caused by ionizing radiation are collectively called radiation dermatitis (RD), and the use of nanomedicine is an attractive approach to this condition. Therefore, we designed and large-scale synthesized fullerenols that showed free radical scavenging ability in vitro. Next, we pretreated X-ray-exposed cells with fullerenols. The results showed that pretreatment with fullerenols significantly scavenged intracellular reactive oxygen species (ROS) produced and enhanced the antioxidant capacity, protecting skin cells from X-ray-induced DNA damage and apoptosis. Moreover, we induced RD in mice by applying 30 Gy of X-ray irradiation, followed by treatment with fullerenols. We found that after treatment, the RD scores dropped, and the histological results systematically demonstrated that topically applied fullerenols could reduce radiation-induced skin epidermal thickening, collagen deposition and skin appendage damage and promote hair regeneration after 35 days. Compared with Trolamine cream, a typical RD drug, fullerenols showed superior radiation protection. Overall, the in vitro and in vivo experiments proved that fullerenols agents against RD.

Abstract
Phage therapy refers to the use of bacteriophages (phages - bacterial viruses) as therapeutic agents against infectious bacterial diseases. This therapeutic approach emerged in the beginning of the 20th century but was progressively replaced by the use of antibiotics in most parts of the world after the second world war. More recently however, the alarming rise of multidrug-resistant bacteria and the consequent need for antibiotic alternatives has renewed interest in phages as antimicrobial agents. Several scientific, technological and regulatory advances have supported the credibility of a second revolution in phage therapy. Nevertheless, phage therapy still faces many challenges that include: i) the need to increase phage collections from reference phage banks; ii) the development of efficient phage screening methods for the fast identification of the therapeutic phage(s); iii) the establishment of efficient phage therapy strategies to tackle infectious biofilms; iv) the validation of feasible phage production protocols that assure quality and safety of phage preparations; and (v) the guarantee of stability of phage preparations during manufacturing, storage and transport. Moreover, current maladapted regulatory structures represent a significant hurdle for potential commercialization of phage therapeutics. This article describes the past and current status of phage therapy and presents the most recent advances in this domain.

Abstract
Radiodermatitis is a common side effect of radiotherapy, but currently there is no standard treatment for its prevention. This study aimed to observe the effect of topical application of a paste based on traditional Chinese medicine, Jiawei Simiao Yongan Gao, on radiodermatitis caused by radiotherapy for patients with head and neck cancer.This was a retrospective cohort study of 40 patients with head and neck cancer evaluated during their radiotherapy. Of these, 20 patients were treated with Jiawei Simiao Yongan Gao on the irradiated skin from the beginning of radiotherapy (JSY group). The other 20 patients were given standard nursing (standard group). Acute skin reactions were classified according to the radiation-induced skin reaction assessment scale (RISRAS) and American radiation therapy oncology group (RTOG) acute toxicity grading criteria every 2 weeks, and adverse effects were recorded until the end of the radiotherapy.The two groups showed differences in severity of radiodermatitis. At 0 to 30 Gy, the skin reactions were similar in the two groups, while above 40 Gy the skin reactions were significantly lower grade in the JSY group (P < .05). At 0 to 20 Gy, there was no statistical significance (P > .05); but above 30 Gy they were lower in the JSY group (P < .05).Jiawei Simiao Yongan Gao effectively alleviated acute radiodermatitis caused by radiotherapy of head and neck cancer patients compared with standard nursing.

Abstract
Radiotherapy (RT) is a major treatment for malignant tumors. The latest data show that >70% of patients with malignant tumors need RT at different periods. Skin changes can be experienced by up to 95% of patients who underwent RT. Inflammation and oxidative stress (OS) have been shown to be generally associated with radiation-induced skin reactions (RISRs). Inflammatory response and OS interact and promote each other during RISRs. Severe skin reactions often have a great impact on the progress of RT. The treatment of RISRs is particularly critical because advanced RT technology can also lead to skin reactions. RISRs are classified into acute and chronic reactions. The treatment methods for acute RISRs include steroid treatment, creams, ointments, and hydrocolloid dressings, depending on the reaction grading. Chronic RISRs includes chronic ulcerations, telangiectasias, and fibrosis of the skin, and advanced treatments such as mesenchymal stem cells, hyperbaric oxygen therapy, superoxide dismutase, and low-intensity laser therapy can be considered. Here, we review and summarize the important mechanisms that cause RISRs as well as the standard and advanced treatments for RISRs.

Abstract
Infection is a leading cause of morbidity and mortality in burn patients. Current therapies include silver-based creams and dressings, which display limited antimicrobial effectiveness and impair healing. The need exists for a topical, point-of-injury antibiotic treatment that provides sustained antimicrobial activity without impeding wound repair. Fitting this description are keratin-based hydrogels, which are fully biocompatible and support the slow-release of antibiotics. Here we develop a porcine model of an infected partial-thickness burn to test the effects of ciprofloxacin-loaded keratin hydrogels on infection and wound healing. Partial-thickness burns were inoculated with either Pseudomonas aeruginosa or Methicillin-resistant Staphylococcus aureus, resulting in infections that persisted for >2 weeks that exceeded 10(5) and 10(6) cfu per gram of tissue, respectively. Compared to silver sulfadiazine, ciprofloxacin-loaded keratin hydrogel treatment significantly reduced the amount of P. aeruginosa and S. aureus in the burn by >99% on days 4, 7, 11, and 15 postinjury. Further, burns treated with ciprofloxacin-loaded keratin hydrogels exhibited similar healing patterns as uninfected burns with regards to reepithelialization, macrophage recruitment, and collagen deposition and remodeling. The ability of keratin hydrogels to deliver antibiotics to fight infection and support healing of partial-thickness burns make them a strong candidate as a first-line burn therapy.

Silver sulfadiazine for the treatment of partial-thickness burns and venous stasis ulcers. J Am Acad Dermatol 2010; 66:e159-65.

Abstract
BACKGROUND For decades silver-containing antibiotics such as silver sulfadiazine (SSD) have been applied as standard topical therapy for patients with partial-thickness burns and venous stasis ulcers. This evidence-based review intends to answer the following research question: in ambulatory patients with partial-thickness burns or stasis dermatitis ulcers, does the use of topical SSD compared with nonantibiotic dressings improve mortality, wound healing, re-epithelialization, or infection rates? METHODS MEDLINE, EMBASE, Cochrane Library, and other databases were searched. We considered trials that enrolled patients of any age with partial-thickness burns or venous stasis ulcers and randomized them to either topical SSD or placebo, saline-soaked gauze, paraffin gauze, sterile dry dressing, or nonantibiotic moist dressing. Outcomes included mortality, wound healing, speed of re-epithelialization, and infection rates. RESULTS For burns, our search revealed 400 potential articles. No human studies met the inclusion criteria. Only 7 animal studies (1 mouse, 4 rat, and 2 pig) were relevant to the proposed question. These animal studies provided conflicting results. Whereas some support the use of SSD for treatment of partial-thickness burns, others question its effectiveness. For stasis dermatitis ulcer, the search identified 50 articles for review, of which 20 abstracts were reviewed, and one article met the inclusion criteria. This study did not show any significant improvement in the rate of complete healing in SSD group compared with placebo either at 4 weeks (relative risk 6.2, 95% confidence interval 0.8-48) or at 1 year (relative risk 5.2, 95% confidence interval 0.6-41.6) of follow-up. CONCLUSION There is insufficient evidence to either support or refute the routine use of SSD for ambulatory patients with either partial-thickness burns or stasis dermatitis ulcers to decrease mortality, prevent infection, or augment wound healing in human beings.

Abstract
This retrospective review examines healing in different sites on a porcine burn model; 24 pairs of burns on 18 pigs from other animal trials were selected for analysis. Each pair of burns was located on the either the cranial or the caudal part of the thoracic ribs region, on the same side of the animal. The burns were 40-50 cm(2) in size and of uniform deep-dermal partial thickness. Caudal burns healed significantly better than cranial burns, demonstrated by earlier closure of wounds, less scar formation and better cosmesis. To our knowledge, this is the first detailed study reporting that burn healing is affected by location on a porcine burn model. We recommend that similar symmetrical burns should be used for future comparative assessments of burn healing.
