Enlightenment on the Construction of Medical Professionalism from the Perspective of Moral Injury / 中国医学伦理学

The purpose of medicine is to preserve and develop the treatment in the process of saving lives and helping injuries. Medical professionalism is a comprehensive expression of physician’s clinical abilities, relationships and values between different subjects. In practice, white robed doctors utilize high standards of professionalism to practice the medical purpose and goals of "always centering on the interests of the patient" in specific diagnosis and treatment behaviors. At the same time, fulfilling the promises and expectations of medicine to the public. For these reasons, selfless dedication, self-sacrifice, and one-way pure altruism are all internalized into the basic requirements of medical professionalism: doctors should not only have the skill to revive the dead, but also have the benevolence of evangelists; they not only need to achieve maximum efficiency in technology, but also achieve the highest truth, goodness, and beauty in virtue. When these qualities are exaggerated or unattainable due to uncontrollable reasons, there will be a rift between the entrenched value systems and practical needs. In recent years, the global epidemic has had a huge impact on the medical system and medical staff, and the moral beliefs, role expectations, and value systems of doctors have also been impacted unprecedentedly, resulting in moral injury. The international research on moral injury in medical field has also received attention. China is currently in the adjustment period of epidemic related policies, with medical personnel bearing the brunt. Therefore, referring to relevant international research on moral injury to re-examine the relationship between the medical professionalism, which emphasizes one-way pure altruism, dedication and weakening or even neglecting personal well-being, and current medical practices. And constructing a moral injury early warning-repair system that focuses on doctors, patients, medical teams, medical institutions, medical environments, health systems, and other stakeholders, and ensuring its healthy operation. Not only in extreme periods, but also in ordinary daily diagnosis and treatment, it can support doctors to actively, safely, and healthily fulfill their mission of saving lives and helping injuries.

The Role of Tumor Microenvironment in Mycosis Fungoides and Sézary Syndrome

Mycosis fungoides (MF) and Sézary syndrome (SS) are the most common subtypes of cutaneous T-cell lymphomas (CTCLs). Most cases of MF display an indolent course during its early stage. However, in some patients, it can progress to the tumor stage with potential systematic involvement and a poor prognosis. SS is defined as an erythrodermic CTCL with leukemic involvements. The pathogenesis of MF and SS is still not fully understood, but recent data have found that the development of MF and SS is related to genetic alterations and possibly to environmental influences. In CTCL, many components interacting with tumor cells, such as tumor-associated macrophages, fibroblasts, dendritic cells, mast cells, and myeloid‐derived suppressor cells, as well as with chemokines, cytokines and other key players, establish the tumor microenvironment (TME). In turn, the TME regulates tumor cell migration and proliferation directly and indirectly and may play a critical role in the progression of MF and SS. The TME of MF and SS appear to show features of a Th2 phenotype, thus dampening tumorrelated immune responses. Recently, several studies have been published on the immunological characteristics of MF and SS, but a full understanding of the CTCL-related TME remains to be determined. This review focuses on the role of the TME in MF and SS, aiming to further demonstrate the pathogenesis of the disease and to provide new ideas for potential treatments targeted at the microenvironment components of the tumor.

Objective:This work aimed to compare the three-year results, prognostic analysis, and adverse reactions of intensi-ty-modulated radiation therapy (IMRT) positioned by PET-CT and conventional radiotherapy in locally advanced non-small cell lung cancer (NSCLC) patients who underwent concurrent chemotherapy. Methods:A clinical trial was carried out in Qingdao Cancer Hospi-tal. The patients who joined our study were divided into IMRT and conventional radiotherapy (CRT) groups. A total of 48 patients were in the IMRT group and another 40 were in the CRT group. The total dose was 60 Gy throughout the 6-week treatment. The plati-num-based concurrent chemotherapy, combined with regimens such as docetaxel, navelbine, and pemetrexed, was conducted for two cy-cles followed by two to four cycles of consolidation chemotherapy. Results:Significant differences were observed between the curative ratio of the IMRT (77.1%) and CRT (52.5%) groups (P=0.015). No significant difference existed between the short-term survival rates of the two groups. The 1-, 2-and 3-year survival rates were 77.1%, 54.2%, and 22.9%in the IMRT group, as well as 65.0%, 47.5%, and 17.5%in the CRT group, respectively. Significant differences existed in some adverse reactions between the two groups, such as radia-tion gastrointestinal reactions, esophagitis, and pneumonia. More patients died of local recurrence and radiation pneumonia in the CRT group than in the IMRT group. The local recurrence rate was also lower in the IMRT group than in the CRT group. Conclusion:IMRT has obvious advantages in improving the short-term curative effect and reducing adverse reactions. Regarding the survival rate, a long-term follow-up of the two groups is required in the future.
