Objective To analyze the clinical characteristics of high energy metabolism in lung cancer patients and its correlation with body composition,nutritional status,and quality of life,and to develop a corresponding risk prediction model.Methods Retrospectively analyzed 132 primary lung cancer patients admitted to the First Hospital of Shanxi Medical University from January 2022 to May 2023,and categorized into high(n=94)and low energy metabolism group(n=38)based on their metabolic status.Differences in clinical data,body composition,Patient Generated Subjective Global Assessment(PG-SGA)scores,and European Organization for Research and treatment of Cancer(EORTC)Quality of Life Questionnaire-Core 30(QLQ-C30)scores were compared between the two groups.Logistic regression was used to identify the risk factors for high energy metabolism in lung cancer patients,and a risk prediction model was established accordingly;the Hosmer-Lemeshow test was used to assess the model fit,and the ROC curve was used to test the predictive efficacy of the model.Results Of the 132 patients with primary lung cancer,94(71.2%)exhibited high energy metabolism.Compared with low energy metabolism group,patients in high-energy metabolism group had a smoking index of 400 or higher,advanced disease staging of stage Ⅲ or Ⅳ,and higher levels of IL-6 level,low adiposity index,low skeletal muscle index,and malnutrition(P<0.05),and lower levels of total protein,albumin,hemoglobin level,and prognostic nutritional index(PNI)(P<0.05).There was no significant difference in age,gender,height,weight,BMI and disease type between the two groups(P>0.05).Logistic regression analysis showed that smoking index≥400,advanced disease stage,IL-6≥3.775 ng/L,and PNI<46.43 were independent risk factors for high energy metabolism in lung cancer patients.The AUC of the ROC curve for the established prediction model of high energy metabolism in lung cancer patients was 0.834(95%CI 0.763-0.904).Conclusion The high energy metabolic risk prediction model of lung cancer patients established in this study has good fit and prediction efficiency.

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.

Objective To detect the expression levels of tumor necrosis factor alpha induced protein 3(TN-FAIP3)and LINC00887 in clear cell renal cell carcinoma(ccRCC)tissue,and to study their relationship with clinical pathological parameters and prognosis.Methods A total of 101 ccRCC patients admitted to the hospi-tal from January 2013 to October 2018 were selected.The expression levels of TNFAIP3 and LINC00887 were detected in ccRCC cancer tissue and paired adjacent tissues,respectively.The relationship between TNFAIP3 and LINC00887 expression and clinical pathological parameters and prognosis of ccRCC patients was analyzed,and the influencing factors of poor prognosis in ccRCC patients were also analyzed.Spearman correlation coef-ficient was used to analyze the correlation between TNFAIP3 and LINC00887 expression.Results The posi-tive rate of TNFAIP3 expression in ccRCC(37.62％)was significantly lower than that in adjacent tissues(52.48％),and the difference was statistically significant(X2=4.500,P=0.034).The expression level of LINC00887 in ccRCC(1.38±0.61)was significantly higher than that in adjacent tissues(1.03±0.43),and the difference was statistically significant(t=5.396,P＜0.001).The positive rates of TNFAIP3 protein in pa-tients with maximum tumor diameter ≥4.5 cm and TNM stage Ⅲ-Ⅳ were lower than those in patients with maximum tumor diameter＜4.5 cm and TNM stage Ⅰ-Ⅱ,and the differences were statistically significant(P＜0.05).The positive rates of LINC00887 in patients with maximum tumor diameter ≥ 4.5 cm,pathologi-cal grading Ⅲ-Ⅳ,and TNM stage Ⅲ-Ⅳ were higher than those in patients with maximum tumor diameter＜4.5 cm,pathological grading Ⅰ-Ⅱ,and TNM stage Ⅰ-Ⅱ,and the differences were statistically signifi-cant(P＜0.05).Compared with the TNFAIP3 high expression group,the TNFAIP3 low expression group had a poorer prognosis,and the difference was statistically significant(x2=5.118,P=0.024).Compared with the LINC00887 low expression group of,the LINC00887 high expression group had a poorer prognosis,and the difference was statistically significant(x2=4.638,P=0.031).Low expression of TNFAIP3,high expres-sion of LINC00887,pathological grade Ⅲ-Ⅳ,and TNM stage Ⅲ-Ⅳ were risk factors for poor prognosis in ccRCC patients(P＜0.05).Spearman rank correlation analysis showed that there was a negative correlation between TNFAIP3 and LINC00887 expression in ccRCC tissue(r=-0.638,P=0.012).Conclusion TN-FAIP3 expression is down-regulated and L1NC00887 expression is up-regulated in ccRCC tissue,and there is a negative correlation.They may jointly regulate the occurrence and development of ccRCC,and have the poten-tial to become tumor markers for evaluating the prognosis of ccRCC patients.

Duodenal neuroendocrine tumors (NETs) are subepithelial tumors that are difficult to remove endoscopically, particularly when located just beyond the pylorus. This paper reports a case of a successful endoscopic submucosal dissection (ESD) using open gastric peroral endoscopic myotomy (POEM) for a remnant duodenal NET detected after endoscopic mucosal resection (EMR). A 67-year-old male presented with a 5 mm remnant duodenal NET close to the pylorus after EMR for a duodenal polypoid lesion performed four months earlier. Duodenal ESD was performed under conscious sedation using I-type and IT II knives. The tumor adhered to the fibrotic tissue, and the submucosal cushion was insufficient. Open gastric POEM was performed concurrently during ESD, resulting in the complete resection of the NET. This case suggests that while challenging, open gastric POEM can serve as a valuable technique for endoscopic resection in cases of early gastric cancer or duodenal masses located around the pylorus.

Interleukin-1 receptor associated kinase 4 (IRAK-4), acting as a serine threonine kinase, is considered as a key signal node for the transduction of IL-1R family and TLRs signal pathway. Studies have found that IRAK-4 has a hand in many signal pathways, involving the inflammatory response of human joints, intestines, liver and nervous system, as well as other autoimmune diseases. It is also one of the causes of drug resistance of some cancer cells. Therefore, IRAK-4 tends to be an effective therapeutic target for inflammatory diseases and cancer. The prospects for the development of drugs in this pathway is to develop novel IRAK-4 small molecule inhibitors and investigate their safety and effectiveness, enrich the clinical treatment of inflammatory and cancer diseases finally. This paper classified and summarized the latest research progress on small molecule inhibitors of IRAK-4 signaling pathway according to structures of the compounds, in order to provide assistances and references for the research and development of related drugs.

Objective:To explore the relationship between workplace procrastination and illegitimate tasks in-kindergarten teachersand the role of work disengagement and coworker support in their relationship.Methods:A to-tal of 245 kindergarten teachers were selected from 3 cities in Zhejiang Province.They were assessed with the Workplace Procrastination Scale(WPS),Bern Illegitimate Tasks Scale(BITS),Work Disengagement Scale(WDS),Colleague Support Scale(CSS).The models were tested by using Process macro for SPSS,and non-para-metric percentile bootstrap method was used to analyze the mediating effect and moderating effect.Results:There were significant differences in the total scores of workplace procrastination among kindergarten teachers in different marital status,age,teaching age,education level,teaching gradeand kindergarten level(Ps＜0.05).Work disengage-ment played a significant mediating role between workplace procrastination and illegitimate tasks(indirect effect=0.26,95％CI:0.16-0.37).Coworker support played a significant moderating role in the impact of illegitimate tasks on work disengagement(simple slope=0.72,0.39;P＜0.001).Conclusion:It suggests that workplace pro-crastination is related to illegitimate tasksin kindergarten teachers.Work disengagement plays a mediating role in their relationship,and coworker support plays a moderating role in the first half of this mediating role.

Objective: To analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ²=4.16, P=0.041) and group C2 (χ²=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ²=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

OBJECTIVE: To explore the relationship between drug treatment and outcomes in patients with late-onset severe pneumonia (LOSP) after allogeneic stem cell transplantation (allo-SCT). METHODS: We retrospectively analyzed the effects of the initiation time of treatment drugs, especially antiviral drugs and glucocorticoids on the clinical outcomes in 82 patients between January 2016 and August 2021 who developed LOSP after allo-SCT in Peking University People's Hospital. Univariate analysis was performed by Mann-Whitney U test and χ² test, and multivariate analysis was performed by Logistic regression. When multiple groups (n>2) were involved in the χ² test, Bonferroni correction was used for the level of significance test. RESULTS: Of all 82 patients in this study, the median onset time of LOSP was 220 d (93-813 d) after transplantation, and the 60-day survival rate was 58.5% (48/82). The median improvement time of the survival patients was 18 d (7-44 d), while the median death time of the died patients was 22 d (2-53 d). Multivariate analysis showed that the initiation time of antiviral drugs from the onset of LOSP (< 10 d vs. ≥10 d, P=0.012), and the initiation time of glucocorticoids from antiviral drugs (< 10 d vs. ≥10 d, P=0.027) were the factors affecting the final outcome of the patients with LOSP at the end of 60 d. According to the above results, LOSP patients were divided into four subgroups: group A (antiviral drugs < 10 d, glucocorticoids ≥10 d), group B (antiviral drugs < 10 d, glucocorticoids < 10 d), group C (antiviral drugs ≥10 d, glucocorticoids ≥10 d) and group D (antiviral drugs ≥10 d, glucocorticoids < 10 d), the 60-day survival rates were 91.7%, 56.8%, 50.0% and 21.4%, respectively. CONCLUSION Our study demonstrated that in patients who developed LOSP after allo-SCT, the initiation time of antiviral drugs and glucocorticoids were associated with the prognosis of LOSP, and the survival rate was highest in patients who received antiviral drugs early and glucocorticoids later. It suggested that for patients with LOSP of unknown etiology should be highly suspicious of the possibility of a secondary hyperimmune response to viral infection.

Hepatic stellate cells (HSCs) play a key role in liver fibrosis. Succinate and succinate receptor (GPR91) signaling pathway are involved in the activation, proliferation, and migration of HSCs. We investigated whether succinate may induce hepatic fibrosis. The mice were randomly divided into 2 groups —the control group (chow diet-fed mice, n = 26) and sodium succinate group (2% sodium succinate + chow diet, n = 38). Each diet was provided for 16 weeks. Mice administered an oral diet of 2% sodium succinate for sixteen weeks lost body weight and had increased serum alanine transaminase and hepatic triglyceride contents compared to those in the control mice. Moreover, mice fed with sodium succinate showed increased expression of the alpha smooth muscle actin protein and gene in the liver at 8 weeks of feeding and increased fibrosis in their histology at 16 weeks of feeding. However, the expression of the GPR91 protein and mRNA increased at 4 weeks of feeding, but decreased at 8 and 16 weeks of feeding. These results suggest that an oral succinate diet could induce liver damage and liver fibrosis in mice and that GPR91 signaling might be an early marker or sensor of hepatic fibrosis development.
