Marine and Agro-Industrial By-Products Valorization Intended for Topical Formulations in Wound Healing Applications

Over the past years, research attention has been focusing more on waste-derived, naturally derived, and renewable materials, in the view of a more sustainable economy. In this work, different topical formulations were obtained from the valorization of marine and agro-industrial by-products and the use of Carbopol 940 as gelling agent. In particular, the combination of extracts obtained from the marine snail, Rapanosa venosa, with Cladophora vagabunda and grape pomace extracts, was investigated for wound healing purposes. Rapana venosa has demonstrated wound healing properties and antioxidant activity. Similarly, grape pomace extracts have been shown to accelerate the healing process. However, their synergic use has not been explored yet. To this aim, four different formulations were produced. Three formulations differed for the presence of a different extract of Rapana venosa: marine collagen, marine gelatin, and collagen hydrolysate, while another formulation used mammalian gelatin as further control. Physico-chemical properties of the extracts as well as of the formulations were analyzed. Furthermore, thermal stability was evaluated by thermogravimetric analysis. Antioxidant capacity and biological behavior, in terms of cytocompatibility, wound healing, and antimicrobial potential, were assessed. The results highlighted for all the formulations (i) a good conservation and thermal stability in time, (ii) a neutralizing activity against free radicals, (iii) and high degree of cytocompatibility and tissue regeneration potential. In particular, collagen, gelatin, and collagen hydrolysate obtained from the Rapana venosa marine snail represent an important, valuable alternative to mammalian products.     

Management of the wound care clinic during the novel coronavirus pneumonia pandemic period: Sharing of management experience in a general hospital of China

With the surge in the confirmed cases of the novel coronavirus pneumonia, medical resources in many countries have been put on red alert levels. The operation management systems of hospitals, including wound care clinics, must be innovated to ensure the normal operation of the hospital and meet the medical care needs of the people. At the same time, scientific control measures are also required to prevent the spread of the novel coronavirus pneumonia in the hospital. Actually, during the novel coronavirus pneumonia pandemic, emergency management methods for wound care clinics such as online appointments and remote online diagnosis and treatment, the rational arrangement of human resources, the scientific implementation of epidemic prevention and control measures, and the strict implementation of the management of the clinic environment and item disinfection measures to strengthen the management of protective materials, wound care materials, and dressing equipment by partition have been introduced and innovated, thus helping reduce the gathering of people in wound care clinics, create a safe medical environment, and avoid the spread of the novel coronavirus pneumonia caused by diagnosis and treatment.     

强力霉素凝胶治疗大鼠口腔溃疡的实验研究

目的研究强力霉素对口腔溃疡的治疗作用,为临床用药提供指导。方法采用60%水醋酸酸蚀SD大鼠口腔颊黏膜建立大鼠溃疡模型。取36只造模成功大鼠随机分为3组,每组12只,分别给予高低剂量强力霉素及空白凝胶作局部治疗,分别于用药第2天、第4天、第6天每组处死4只大鼠,经过切取标本,石蜡包埋,制片,HE染色、麦氏染色和免疫组化染色后,于光镜下进行观察。结果用药后,强力霉素高低剂量组较对照组炎性渗出明显减少,充血情况明显减轻,胶原纤维降解、MMP-9的表达明显减少,溃疡愈合更快。结论强力霉素可能是通过抑制MMP-9的表达,减少胶原纤维的降解,促进口腔溃疡愈合。     

采用化学烧灼法复制豚鼠口腔溃疡模型的效果评价及体会

目的本文就在实验过程中遇到的问题,造模效果及一些经验体会做一报道,为其他工作者提供参考。方法采用化学烧灼法复制豚鼠口腔溃疡模型。结果造模24h后,豚鼠口腔颊粘膜被烧灼区形成溃疡,周围组织明显红肿隆起,粘膜表面粗糙不平,有黄色假膜。结论该法简便易行,可操作性强,但如不严格控制实验条件,所形成的粘膜损伤不稳定,会给实验结果带来很大的误差。     

Safety of mTOR inhibitor continuation in pediatric heart transplant recipients undergoing surgical procedures

mTOR inhibitors have been associated with SWC when used in the perioperative period. Limited literature is available to guide providers in managing chronic mTOR inhibitor use in the perioperative period, especially in the pediatric setting. The primary aim of this study was to describe the prevalence of SWC with mTOR inhibitor continuation during the perioperative period for major surgeries. Heart transplant recipients ≤25 years old at the time of primary heart transplant receiving sirolimus maintenance therapy during a surgical procedure and within the study period were included. Surgeries identified within the study period included otolaryngology procedures (46.2%), such as tonsillectomies with or without adenoidectomies, cardiac surgeries (30.8%) including a sternal revision, pulmonary vein repair, and pacemaker placement in two patients, orthopedic surgeries (15.4%) including a posterior spinal fusion and an Achilles tendon lengthening with ankle and subtalar joint release, and a neurosurgery (7.7%), which was a ventriculoperitoneal shunt revision. Thirteen surgical encounters were examined. One SWC was observed, an infected pacemaker requiring systemic antibiotics and removal of the device. The results of this study suggest that sirolimus may be continued in the perioperative period based on the low rate of SWC observed.
