Objective To examine the precise function of influenza A virus target genes(IATGs)in malignancy. Methods Using multi-omics data from the TCGA and TCPA datasets,33 tumor types were evaluated for IATGs.IATG expression in cancer cells was analyzed using transcriptome analysis.Copy number variation(CNV)was assessed using GISTICS 2.0.Spearman's analysis was used to correlate mRNA expression with methylation levels.GSEA was used for the enrichment analysis.Pearson's correlation analysis was used to examine the association between IATG mRNA expression and IC50.The ImmuCellAI algorithm was used to calculate the infiltration scores of 24 immune cell types. Results In 13 solid tumors,IATG mRNA levels were atypically expressed.Except for UCS,UVM,KICH,PCPG,THCA,CHOL,LAMI,and MESO,most cancers contained somatic IATG mutations.The main types of CNVs in IATGs are heterozygous amplifications and deletions.In most tumors,IATG mRNA expression is adversely associated with methylation.RT-PCR demonstrated that EGFR,ANXA5,CACNA1C,CD209,UVRAG were upregulated and CLEC4M was downregulated in KIRC cell lines,consistent with the TCGA and GTEx data. Conclusion Genomic changes and clinical characteristics of IATGs were identified,which may offer fresh perspectives linking the influenza A virus to cancer.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Objective:To explore the mechanism of 14-3-3σgene in regulating inflammatory response of human pulmonary epithelial cells induced by endotoxin/lipopolysaccharide (LPS).Methods:(1) Cells of human normal pulmonary epithelial cell line BEAS-2B cultured in logarithmic growth period were collected and divided into control group and PCMV6-14-3-3σgroup using the random number table, with 3 wells in each group. Cells in control group were transfected with empty plasmid, and cells in PCMV6-14-3-3σgroup were transfected with PCMV6-14-3-3σplasmid. The protein expression of 14-3-3σin cell was detected by Western blotting at 48 hours after transfection. (2) Cells of human normal pulmonary epithelial cell line BEAS-2B cultured in logarithmic growth period were collected and divided into control group, PCMV6-14-3-3σgroup, PCMV6-14-3-3σ+ LPS group, and LPS group using the random number table, with 3 wells in each group. Cells in control group were transfected with empty plasmid for 42 hours. Cells in PCMV6-14-3-3σgroup were transfected with PCMV6-14-3-3σplasmid for 42 hours. Cells in PCMV6-14-3-3σ+ LPS group were stimulated with 1 μg/mL LPS (the same final mass concentration below) for 6 hours after being transfected with PCMV6-14-3-3σplasmid for 42 hours. Cells in LPS group were stimulated by LPS for 6 hours. The protein expressions of Bax and B-cell lymphoma-2 (Bcl-2) were detected by Western blotting, and the ratio of Bax to Bcl-2 was calculated. Apoptotic rate was detected by flow cytometry. The mRNA expressions of tumor necrosis factor alpha (TNF-α) and interleukin 1beta (IL-1β) in cells were detected by real-time fluorescent quantitative reverse transcription polymerase chain reaction technique. Content of TNF-α and IL-1β in cell culture supernatant was detected by enzyme-linked immunosorbent assay. Data were statistically analyzed with t test, one-way analysis of variance, and least significant difference test. Results:(1) At 48 hours after transfection, the protein expression of 14-3-3σin cells of PCMV6-14-3-3σgroup (1.05±0.03) was significantly higher than that in control group (0.78±0.04, t=5.41, P<0.01). (2) Compared with those in control group, the ratio of Bax to Bcl-2, apoptotic rate, mRNA expressions of TNF-α and IL-1β, and content of TNF-α and IL-1β in cell supernatant in PCMV6-14-3-3σgroup showed no significant difference ( P>0.05); the above-mentioned indexes of cells in LPS group were significantly higher or increased ( P<0.01). Compared with those in LPS group, the above-mentioned indexes of cells in PCMV6-14-3-3σ+ LPS group were significantly lower or decreased ( P<0.01). Conclusions:14-3-3σis a key factor in regulating apoptosis. It can alleviate the LPS-induced inflammatory responses by regulating the ratio of apoptotic regulators Bax to Bcl-2 and inhibiting apoptosis of human pulmonary epithelial cells.

Objective To explore the methods and effects of parents chaperone for premature infants with bronchopulmonary dysplasia(BPD)in neonatal intensive care unit(NICU).Methods Convenience sampling method was used to recruit premature infants diagnosed with BPD admitted from January 2014 to October 2016 in NICU in a tertiary hospital,and 41 premature infants were recruited and divided into the control group (n=19) and the experimental group(n=22) according to the time sequence of admission.Infants in the experimental group was accompanied by parents when diagnosed as BPD,and under the guidance of specialty nurses,parents performed daily care,observation of condition,treatment assistance,and early intervention;infants in the control group were provided traditional nursing mode,nurses performed nursing care,and parents were allowed to visit through the window for one hour each time,three times every week.Parental anxiety was compared between two groups at 1 day before discharge,and follow-up compliance and weight gain of infants were compared at 3 days,7 days,2 weeks,4 weeks after discharge.Results Parental anxiety at 1 day before discharge,and follow-up compliance and weight gain of infants in the experimental group were all better than those in the control group,and the differences were statistically significant(P＜0.05).Conclusion Parents chaperone can improve parents' ability of caring,reduce parents' anxiety and improve follow-up compliance after discharge,so as to improve quality of life of premature infants with BPD.

Cerebral stroke has a high incidence, mortality and disability rate, which lead to many se-quelae especially hemiplegia. Patients who got hemiplegia always had limb dysfunction and cannot live on their own, so the burden of taking care of patients are on the shoulder of caregivers. This paper reviewed the needs of caregivers from the following four parts: the classification of caregivers' needs, the influencing factors of the de-mand, the evaluation methods of the demand and the interventions that the caregivers need. From this article we know the needs of caregivers would change with the change of the state of patients, but their needs generally in-clude the disease knowledge, exercise guidance, emotion management, and community resource utilization, etc.
