Ferroptosis is regarded as a novel and regulatable form of cell death, with its main characteristics being abnormal iron metabolism and the accumulation of lipid peroxides. Although there have been breakthroughs in the research of ferroptosis in tumors and degenerative diseases, its research in skin diseases is relatively scarce. Starting from the development of the concept of ferroptosis, this article expounds the basic characteristics and regulatory mechanisms of ferroptosis. In the field of skin diseases, we emphasize the importance of ferroptosis and discuss in detail the research and application of ferroptosis in various skin diseases, aiming to provide effective guidance for the treatment and clinical practice of various skin diseases, and offer new ideas for the future research direction of skin diseases.

To analyze the clinical characteristics and follow-up data of Chinese patients with calcium-sensing receptor (CaSR) signaling pathway related hypercalcemia. A retrospective analysis was conducted on six children with hypercalcemia admitted to Department of Endocrinology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from July 2017 to November 2022. Summarized the clinical and pathogenic variants, as well as follow-up data. The results showed that 3 were female and 3 were male of the 6 cases, aged from 2 months to 8 years at the consultation. The clinical symptoms varied from asymptomatic hypercalcemia to vomiting, dehydration, and growth retardation,as well as epilepsy and intellectual disability. Except for 1 case, which showed a significant increase in blood calcium (4.63 mmol/L), the blood calcium of other cases ranged from 2.98 to 3.17 mmol/L. Among the 6 patients, 5 had elevated parathyroid hormone, and 1 was normal. Three cases showed a significant decrease in 24-hour urinary calcium to creatinine ratio. Whole exome sequencing revealed that one patient had compound heterozygous variants and four had a heterozygous variants of CaSR gene, one patient had a heterozygous variant of AP2S1 gene. 1 case underwent total parathyroidectomy, followed by calcium supplementation, 3 cases received salmon calcitonin treatment, and 2 cases accepted low calcium diet, blood calcium levels were all controlled well. In conclusion, CaSR signaling pathway related hypercalcemia is rare. Gene detection is essential for children with hypercalcemia. Familial hypocalcemia hypercalcemia (FHH) can be effectively treated with salmon calcitonin.

Subcutaneous panniculitis-like T-cell lymphoma (SPTL) is an extremely rare, indolent skin malignancy that can be difficult to distinguish from autoimmune disease-associated panniculitides. Here, we describe a 12-year-old boy who was diagnosed at age 7 years with dermatomyositis with classical manifestations, including poikiloderma, Gottron’s sign, and symmetric muscle weakness. Recently, the boy presented multiple subcutaneous nodules and fever. Histopathological examination and immunohistochemical staining revealed coexistence of SPTL. To our knowledge, this is the first case of dermatomyositis accompanied with SPTL. This case alert clinical physicians of the possibility of SPTL should be considered when a patient with dermatomyositis has new lesions presenting as nodules and unknown fever.

Objective:To evaluate the clinical status, and analyz obstacles and facilitators for perioperative deep vein thrombosis prevention of brain neoplasms based on the Ottawa model of research use (OMRU).Methods:A total of 93 patients with brain tumors who were admitted to the Department of Neurosurgery, the First Affiliated Hospital of Nanjing Medical University from April to May 2021 and 33 nurses in the neurosurgery ward and operating room neurosurgery special group were selected as the baseline review subjects by convenience sampling. Based on the framework of evidence-based continued quality improvement of Fudan University, we searched BMJ Best Practice, UpToDate, The Joanna Briggs Institute Library, International Guideline Library, American Guideline Network, Scottish Intercollegiate Guideline Network, National Institutes for Health and Clinical Technology Optimization, Medline, Medlive, China National Knowledge Infrastructure, VIP, Wanfang and SinoMed according to the '6S' evidence pyramid from inception to January 1, 2021 for all clinical decisions, recommended practices, best practice information, evidence summary, guidelines and expert consensus on venous thrombosis assessment, prevention, screening, nursing and health education. The best evidence was summarized, and the final review indicators were formulated through two rounds of expert correspondence. According to the results of baseline review, barriers and facilitators were analyzed, and countermeasures were developed guided by OMRU.Results:A total of 19 best evidences were included, and 34 review indicators were developed in this study. Among them, only 4 indicators had a compliance rate of 100%, 18 ones had a compliance rate of 0, and the other 12 ones had a compliance rate of 6.5%-97.8%. A multi-factor analysis of the review results showed that the main obstacles of evidence implementation were the feasibility and comprehensibility at evidence level, the lack of knowledge and heavy workloads at the potential practitioner level, insufficient education materials, trainings and preventive equipment at system level. Furthermore, the reliable sources of evidence at evidence level, supports from practitioners at the potential practitioner level and system resources (such as training, national and hospital policies, etc.) at system level may contribute to the clinical application of evidence.Conclusions:There was still a huge gap between the best evidence and clinical practice. The obstacles and facilitating factors in evidence transformation should be evaluated scientifically and comprehensively, and corresponding countermeasures should be given to promote the application of evidence in clinical practice.

Objective:To develop an inquiry learning community centered on learning experience in the course of Nursing Clinical Comprehensive Experiment to verify the influence of this teaching mode on the learning gains and practical ability of nursing students. Methods:A total of 132 undergraduate nursing students form grade 3 in Chongqing Medical University were enrolled. The participants were randomly assigned to a learning community group ( n = 69) and a control group ( n = 63) using Minitab 14.0 software. The students in the learning community group adopted the inquiry learning community mode in accordance with the curriculum map for online self-learning, group discussion and skills practice, while the control group received the teacher-led teaching mode for offline theory teaching, operation teaching and skills practice. After the teaching intervention, both groups of students received the assessment questionnaire of learning gains and the comprehensive experimental ability evaluation. Chi-square test or paired t-test was performed using SPSS 23.0. Results:Compared with the control group, students in the learning community group reported that their sense of learning gain was enhanced ( P<0.001, Cohen d=0.97); sub-items showed that the effect size for the understanding of learning content ( P<0.001, Cohen d=1.22), the overall course situation ( P<0.001, Cohen d=0.90), the course activities ( P=0.000, Cohen d=0.83), and the information obtained ( P<0.001, Cohen d=1.16) was significantly different. The total score of practical ability of comprehensive experiment was significantly improved ( P = 0.005, Cohen d=0.51), in which the experimental situation displays ( P=0.002, Cohen d=0.55) and experimental effect ( P=0.006, Cohen d=0.49) were better than the control group. There was no significant difference in the performance of experimental preparation and case analysis between the two groups. Conclusion:Developing an inquiry learning community in nursing clinical comprehensive experiment can effectively enhance student' sense of learning gains and promote the improvement of clinical practical ability.

Objective:To explore the relationship between stigma, psychological resilience and quality of life in patients with stable schizophrenia.Methods:This study is a cross-sectional study. From January to December 2021, 305 patients with stable schizophrenia who were treated in the Outpatient Department of the Affiliated Brain Hospital of Nanjing Medical University were selected by convenient sampling. The survey was carried out by using the General Information Questionnaire, the World Health Organization Quality of Life-Brief Form (WHOQOL-BREF) , the Connor-Davison Resilience Scale (CD-RISC) , and the Perceived Devaluation Discrimination (PDD) . Pearson correlation analysis was used to analyze the relationship between quality of life, stigma and psychological resilience of schizophrenia patients. The structural equation model was established using AMOS 25.0 and the intermediary effect was verified. A total of 305 questionnaires were distributed and 286 valid questionnaires were recovered, with an effective recovery rate of 93.8% (286/305) .Results:Among 286 patients with stable schizophrenia, the scores of psychological resilience, stigma and quality of life were (56.49±14.28) , (29.62±5.70) and (63.15±11.67) respectively. There was a positive correlation between the psychological resilience and the quality of life ( r=0.461, P<0.01) , a negative correlation between the stigma and the quality of life ( r=-0.328, P<0.01) , and a negative correlation between the stigma and the psychological resilience ( r=-0.309, P<0.01) . The results of intermediary effect analysis showed that psychological resilience played a part of intermediary role between the stigma and the quality of life, and the indirect effect was statistically significant (β=- 0.167, P<0.001) , the intermediary effect accounted for 32.2% of the total effect. Conclusions:Psychological resilience is an intermediary variable between the stigma and the quality of life in patients with stable schizophrenia. Nurses should carry out intervention strategies based on the impact of psychological resilience path to reduce the patients' stigma and improve their quality of life.
