Objective To analyze the application effect of ultra early stepped collaborative nutrition management on improving feeding in patients with severe acute pancreatitis．Methods Eighty patients with severe acute pancreatitis admitted to our hospital from January 2020 to January 2022 were selected as research subjects and randomly divided into observation group and reference group,with 40 cases in each group．Patients in both groups were given conventional nutritional intervention measures,among which patients in the observation group were given super-early stepped collaborative nutritional management on the basis of the above．Clinical symptom resolution time,nutritional status,feeding related complications and feeding intolerance rate were compared between the two groups．Results Compared with the reference group,the time of clinical symptoms resolution in the observation group was shorter（P<0.05）,and the body mass index,upper arm muscle circumference,triceps skin fold thickness and serum albumin level in the observation group were higher（P<0.05）．The feeding-related complications of the two groups mainly included nausea and vomiting,aspiration,diarrhea and infection．The incidence of feeding-related complications in the observation group was 7.50%,and that in the reference group was 25.00%．The incidence of feeding-related complications in the observation group was lower（P<0.05）．There were 2 cases of feeding intolerance in the observation group,the feeding intolerance rate was 5.00%,and 9 cases of feeding intolerance in the reference group,the feeding intolerance rate was 22.50%,the feeding intolerance rate in the observation group was lower（P<0.05）．Conclusions Implementing ultra early stepped collaborative nutritional management in patients with severe acute pancreatitis can reduce the incidence of feeding intolerance and feeding related complications,and improve nutritional levels．

CCAAT增强子结合蛋白A（CEBPA）是调节血液发育过程中髓系分化和造血干祖细胞活性的关键转录因子之一。CEBPA基因突变常见于急性髓系白血病（AML）中,最近研究表明CEBPA bZIP框内单位点和经典双等位基因突变AML患者均具有类似的临床特征,已被单独划分为AML亚群。CEBPA bZIP框内突变而非传统的双等位CEBPA基因突变成为AML良好预后的分子指标,表明其在AML疾病进展和治疗预后中的重要性和特殊性。本文将从CEBPA蛋白在血液系统中的功能、CEBPA bZIP框内突变AML的临床特征与分子作用机制、以及伴CEBPA突变AML的治疗现状等方面进行综述,为进一步研究CEBPA bZIP框内突变在AML中的致病性和精准治疗新药物开发提供参考。

CCAAT enhancer-binding protein A（CEBPA）is one of the key transcription factors regulating myeloid differentiation and hematopoietic stem/progenitor cell maintenance during hematopoiesis．CEBPA gene mutations are commonly found in acute myeloid leukemia（AML）．Recent studies have demonstrated that AML patients haboring single CEBPA bZIP in-frame mutations or classical bi-allelic CEBPA mutations show similar clinical features and it has been individually classified as AML subgroup．Additionally,it is CEBPA bZIP in-frame mutations rather than the traditional biallelic CEBPA mutations that have emerged as a molecular indicator of favorable prognosis for clinical AML management,suggesting its importance and specificity in AML disease progression and therapeutic prognosis．Here,we reviewed serval aspects including the hematopoietic function of CEBPA protein,the clinical features and molecular mechanisms of AML with CEBPA bZIP in-frame mutations,and the current status of the treatment of AML with CEBPA mutations,which will provide a reference for further study of the pathogenicity of CEBPA bZIP in-frame mutations in AML and the development of new drugs for precision therapy．

Objective To compare the efficacy of modified and conventional trabeculectomy in the treatment of acute angle-closure glaucoma（AACG）based on best-corrected visual acuity（BCVA）and degree of corneal edema．Methods A total of 112 patients with AACG admitted to the hospital during December 2021 to June 2023 were retrospectively selected as study objects． According to the 1∶1 matching principle,56 patients receiving conventional trabeculectomy were selected as control group,and 56 patients receiving modified trabeculectomy were selected as observation group．Perioperative BCVA,intraocular pressure,postoperative shallow anterior chamber formation,degree of corneal edema and complications were analyzed．Results At three months postoperatively,visual acuity in the observation group was（0.63±0.04）logMAR,which was higher than that in the control group（0.50±0.03）logMAR,and intraocular pressure was（16.22±2.28）mmHg,which was lower than that in the control group（19.95±2.31）mmHg（t=19.457,8.600,P<0.05）;the incidence of shallow anterior chamber in the observation group was 8.93%,which was lower than that of the control group（26.79%）（χ²=6.087,P=0.014）;the corneal edema status in the observation group was better than that of the control group（Z=2.737,P=0.006）;the rates of choroidal detachment,filtering channel obstruction,hyphema,and iris inflammation in the observation group were 1.79%,5.36%,16.07%,and 10.71%,respectively,which were lower than those of the control group（17.86%,23.21%,32.14%,and 35.71%）（χ²=8.166,7.292,3.953,and 9.818,P<0.05）．Conclusions Compared with conventional trabeculectomy,modified trabeculectomy can improve visual acuity,reduce intraocular pressure,relieve corneal edema,and reduce the occurrence of shallow anterior chamber in patients with AACG,with higher safety．

Objective To explore the occurrence and influencing factors of acute adverse reactions of iodine contrast agents in enhanced computed tomography（CT）. Methods A retrospective analysis was conducted on 100 patients admitted to our hospital from October 2020 to October 2023 who experienced acute adverse reactions to iodine contrast agents during CT enhancement．They were divided into an observation group and another 100 patients who underwent CT enhancement examination in our hospital during the same period without any adverse reactions were selected as the control group．The acute adverse reactions of iodine contrast agent in the observation group of patients were analyzed,the clinical data and injection of iodine contrast agent between the two groups of patients were compared,and include acute adverse reactions as the dependent variable（occurrence of acute adverse reactions=1,absence of acute adverse reactions=0）was used in the Logistic regression model to analyze the independent influencing factors of acute adverse reactions of CT enhanced iodine contrast agent．Results Among the 100 patients who experienced acute adverse reactions to iodine contrast agents,65 were mild reactions,accounting for 65.00%,34 cases had were moderate reactions,accounting for 34.00%,and one cases had severe reactions,accounting for 1.00%．There was no significant difference between the observation group and the control group in gender,age,body mass index（BMI）,history of hypertension,diabetes,heart dysfunction,hyperthyroidism,coronary heart disease,use of iodine contrast agent,and food allergy（P>0.05）．The history of asthma（9.00% vs 2.00%）,renal insufficiency（13.00% vs 3.00%）,adverse reactions of iodine contrast（21.00 % vs 2.00%）,pollen allergy（12.00% vs 4.00%）,drug allergy（26.00% vs 7.00%）and other allergies（10.00 % vs 2.00%）were significantly different（χ²=4.710,P=0.030;χ²=6.790,P=0.009;χ²=17.740,P<0.001;χ²=4.350,P=0.037;χ²=13.100,P<0.001;χ²=5.670,P=0.017）．There was no significant difference in the dosage of iodine contrast agent between the observation group and the control group（P>0.05）．The injection rate of iodine contrast agent between the observation group and the control group（< 3 mL/min was 55.00% vs 69.00%;≥3 mL/min was 45.00% vs 31.00%）,and the types of iodoxanol （iodoxanol[34.00% vs 34.00%],iodoxanol[47.00% vs 30.00%],iodohexanol[19.00% vs 36.00%]） were significantly different（χ²=4.160,P=0.041;χ²=9.010,P=0.011）．History of renal insufficiency,adverse reactions to iodine contrast agents,drug allergies,other allergies,and injection speed of iodine contrast agents were independent risk factors for the occurrence of acute adverse reactions to iodine contrast agents（P<0.05）．Conclusions Acute adverse reactions to iodinated contrast agents in CT enhancement are mostly mild．Previous history of renal insufficiency,history of adverse reactions to iodinated contrast agents,history of drug allergies,other allergic histories,and high injection speed of iodinated contrast agents may be influencing factors for the occurrence of adverse reactions to iodinated contrast agents．
