As one of the hallmarks of cancer, metabolic reprogramming leads to cancer progression, and targeting glycolytic enzymes could be useful strategies for cancer therapy. By screening a small molecule library consisting of 1320 FDA-approved drugs, we found that penfluridol, an antipsychotic drug used to treat schizophrenia, could inhibit glycolysis and induce apoptosis in esophageal squamous cell carcinoma (ESCC). Gene profiling and Ingenuity Pathway Analysis suggested the important role of AMPK in action mechanism of penfluridol. By using drug affinity responsive target stability (DARTS) technology and proteomics, we identified phosphofructokinase, liver type (PFKL), a key enzyme in glycolysis, as a direct target of penfluridol. Penfluridol could not exhibit its anticancer property in PFKL-deficient cancer cells, illustrating that PFKL is essential for the bioactivity of penfluridol. High PFKL expression is correlated with advanced stages and poor survival of ESCC patients, and silencing of PFKL significantly suppressed tumor growth. Mechanistically, direct binding of penfluridol and PFKL inhibits glucose consumption, lactate and ATP production, leads to nuclear translocation of FOXO3a and subsequent transcriptional activation of BIM in an AMPK-dependent manner. Taken together, PFKL is a potential prognostic biomarker and therapeutic target in ESCC, and penfluridol may be a new therapeutic option for management of this lethal disease.

At present, there are some problems in doctor-patient communication in standardized residency training in department of burns, such as insufficient understanding, lack of communication skills and short of teachers' guidance. Therefore, during the rotation of burns department, we should strengthen the cultivation of communication ability by improving humanistic care, professional level and communication training. At the same time, clinical teachers should strengthen their own quality and the assessment system should be improved. Through comprehensive efforts in many aspects, we will improve doctor-patient communication ability and build a harmonious doctor-patient relationship.

Metabolic disorder is one of the most obvious pathophysiological characteristics of patients with severe burn or trauma, which leads to high mortality of patients with severe burn or trauma. Metabonomics is a newly developed subject which provides new research concepts and ideas for studying the changes of metabolism in a disease condition. Based on the analysis of group indicators, metabonomic technique not only can systematically study the change rules of metabolites, which helps to further clarify the pathophysiological mechanism of burn or trauma, but also is helpful to find some significant biomarkers with important clinical value so as to provide new insight for the therapy of burn or trauma. This paper reviews the research progress of application of metabonomics in the treatment of severe burn or trauma in recent years.
