Recently, electrical stimulation as a physical stimulus draws lots of attention. It shows great potential in disease treatment, wound healing, and mechanism study because of significant experimental performance. Electrical stimulation can activate many intracellular signaling pathways, and influence intracellular microenvironment, as a result, affect cell migration, cell proliferation, and cell differentiation. Electrical stimulation is using in tissue engineering as a novel type of tool in regeneration medicine. Besides, with the advantages of biocompatible conductive materials coming into view, the combination of electrical stimulation with suitable tissue engineered scaffolds can well combine the benefits of both and is ideal for the field of regenerative medicine. In this review, we summarize the various materials and latest technologies to deliver electrical stimulation. The influences of electrical stimulation on cell alignment, migration and its underlying mechanisms are discussed. Then the effect of electrical stimulation on cell proliferation and differentiation are also discussed.
However, increasing evidence suggest that silibinin is not solely limited in the treatment of these diseases. Further research suggests that silymarin may function diversely and may serve as a novel therapy for cancer therapy, such as lung cancer, prostatic cancer, colon cancer, breast cancer, bladder cancer and hepatocellular carcinoma by regulating cancer cells growth, proliferation, apoptosis, angiogenesis and many other mechanism. Expert commentary: In this review, in order to provide potential new treatment for these cancer, we summarize the recent anti-cancer findings of silibinin in these cancer and clarify the mechanisms of this effect.
NK/T cell lymphoma (NKTCL) is a common disease which is a threat to human health. Nasal NKTCL is a rare but serious type of systemic lymphoma because of its high mortality rate and serious complications. In this case report, we describe a male who presented with nasal blockage in the right side, a fever of one month duration and a soy-like, painless and gradually increasing mass in the right submandibular region due to nasal NKTCL. The patient had no significant medical history and the initial clinical symptoms were nasal blockage. Contrast computed tomography showed that the nasopharyngeal mucosa was thickened and that the celiac and retroperitoneal lymphaden was intumescent. Finally a biopsy, guided by nasal endoscopy and examined using flow cytometry confirmed a diagnosis of NKTCL. Nasal NKTCL is rare and has no unique characteristics at first presentation, such as epidemiology and obvious clinical manifestation. As no effective therapy is currently available for this disease, early diagnosis and therapy of nasal NKTCL remains challenging.
Background:Cholesterol pericarditis (CP) is a special type of pericarditis. It is characterized by chronic pericardial effusion with high cholesterol concentration and with or without the formation of crystals in pericardial effusion.Methods:In this case report, we described a 74-year-old male with massive pericardial effusion. He presented with no symptoms. However, he had 8-year history of rheumatoid arthritis medicated with methotrexate, celecoxib, and prednisone, and 5-year history of hypertension medicated with amlodipine besylate. On admission, transthoracic echocardiography revealed a large pericardial effusion.Results:We performed pericardiocentesis for this patient and a lot of cholesterol crystals were found in pericardial effusion under the microscope. A successful operation of thoracoscopic pericardiectomy was proceeded, and the diagnosis was confirmed by surgical pathology. The patient was well recovered and discharged on the tenth day after surgery. It could be predicted that pericardiectomy under video-assisted thoracoscope could be a promising therapy for CP.Conclusion:Rheumatoid arthritis may cause CP with no symptoms. Pericardiectomy could be a promising therapy for CP.
Introduction:Atrial-esophageal fistula (AEF) is a rare severe disease, which may be associated with radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) or intraoperative radiofrequency ablation of atrial fibrillation (IRAAF).Clinical Findings:We reported a case of a 67-year-old man with AEF following RFCA of AF, who treated with esophageal stenting and surgical repair.Outcomes:He was attacked by out-of-control sepsis and infectious shock after surgery and died.Literature review:We analyzed 57 relevant articles about AEF from 2003 to 2015 by searching PubMed database. According literatures, the most common symptoms were fever, rigor, sepsis, and neurologic symptoms. Chest computer tomography (CT) and contrast enhanced CT may be the reliable noninvasive diagnosis methods because of high sensitive for AEF.Conclusion:Make a definition diagnosis in time with early primary surgical repair may save their lives. Conservative treatment or esophageal stenting alone may not be a better choice for AEF patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
