Esophageal cancer is a prevalent malignant tumor of the digestive tract in China, and radical surgery remains the cornerstone of its comprehensive treatment. However, multifactorial challenges such as postoperative gastrointestinal tract reconstruction, traumatic stress, and tumor-related metabolic disturbances render esophageal cancer patients highly susceptible to malnutrition. Perioperative nutritional support therapy plays a crucial role in enhancing surgical safety, improving clinical outcomes, and elevating patients' quality of life by regulating metabolic homeostasis, preserving organ function, and optimizing the immune microenvironment. This article reviews the mechanisms underlying malnutrition in esophageal cancer, methods for nutritional status assessment, and precision intervention pathways based on multi-omics evaluations. The aim is to strengthen clinicians' awareness of standardized perioperative nutritional management for esophageal cancer patients and promote its clinical implementation, thereby facilitating postoperative recovery and improving long-term quality of life.

[摘 要] 目的：探讨嗜酸性粒细胞（Eos）和其他循环血细胞和炎症指标在预测小细胞肺癌（SCLC）免疫治疗疗效和免疫相关不良反应（irAE）中的价值。方法:回顾分析2013年8月至2023年7月期间海军军医大学第一附属医院呼吸科收治的410例SCLC患者临床信息；在化疗或免疫治疗前，以及治疗后的3个周期，分别检测患者全血细胞计数和细胞因子等指标；记录irAE的发生时间、类型、分级，以及随访情况。结果: 接受化疗联合免疫检查点抑制剂（ICI）治疗（简称联合治疗）的患者116例，其中一线联合治疗患者91例、后线联合治疗25例。联合组患者的总有效率（ORR）为44.8%，疾病控制率（DCR）为90.5%，单用化疗（单化）组患者的ORR为38.4%，DCR为85.0%。联合组中位PFS为8.9（7.2～10.5）个月，中位OS为17.7（13.9～21.5）个月。将联合组与单化组行倾向得分匹配（PSM）法配对，对比二组治疗后3周期的绝对嗜酸性粒细胞计数（AEC）水平、相对嗜酸性粒细胞计数（REC）水平；计算历次复查Eos水平与基线Eos水平的比值（AECT1/0、AECT2/0、AECT3/0、RECT1/0、RECT2/0、RECT3/0），联合组的AECT3/0和RECT3/0显著高于单化组。单因素分析表明，基线AEC和REC的升高与较好的治疗至失败时间（TTF）和OS显著相关（P < 0.05）；治疗后Eos水平与基线水平的比例（AECT3/0、RECT3/0）与较好的PFS和TTF显著相关（P < 0.05）；RECT3/0升高同样与OS改善显著相关（P < 0.05）。多因素分析提示，AECT3/0 > 0.41与较好的PFS和TTF显著相关（P < 0.05）；当RECT3/0 > 0.32时，与较好的PFS、TTF、OS均显著相关（P < 0.05）；RECT3/0 > 0.27仅与较好的TTF、OS显著相关（P < 0.05）。亚组分析发现，缓解组的RECT3/0显著高于非缓解组（P < 0.05）。一线应用ICI与二线/后线应用ICI患者的PFS、TTF、OS无统计学差异，但一线应用ICI时ORR（50% vs 25%，P < 0.05）和DCR（93.48% vs 79.17%，P < 0.05）显著优于二线/后线。116例联合治疗患者发生43例irAE（35.34%）, 最常见的为免疫相关性皮炎8.62%；Ⅲ级以上的irAE共17例（14.66%）；因irAE停药10例（8.62%），死亡2例;发生irAE的患者PFS较未发生irAE的患者显著延长（P < 0.05），而TTF和OS无统计学差异。发生irAE患者的RECT3较未发生irAE患者显著升高（P < 0.05），AECT3/0 > 0.29的患者irAE发生率显著增高（P < 0.05）。结论: Eos是SCLC接受ICI治疗的保护性因素，通过监测AECT3/0、RECT3/0，并结合患者的临床病理生理特征、细胞因子和炎症标志物水平进行综合评估，可有效预测SCLC患者的免疫治疗疗效和irAE的发生。

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Objective To analyze the infection status and epidemic trends of soil-borne nematode infections in Yubei, Chongqing City, in 2010,2021, and 2022. Methods The local populations from four survey sites of four towns in 2010 and five sites of five towns in 2021 and 2022 were surveyed regarding their basic information using a unified form. Fecal samples of the participants were collected and tested for soil-borne nematode infections using the modified Kato-Katz thick smear method. Results In 2010, 2 049 participants were surveyed, followed by 1 000 participants in 2021 and 2022. The overall prevalence of parasitic infections declined significantly from 3.86% to 0.20%. In 2010, soil-transmitted nematode included hookworms(3.81%) and roundworms(0.29%). In 2021, the infection rates of roundworms and hookworms were 1.70% and 0.10% respectively. Notably, only Ascaris was identified in 2022(0.20%). The≥60 age group consistently exhibited the highest infection rates across all surveys, followed by the 40-59 age group. The infection rates of males in the three surveys were 3.31%,1.92%, and 0.20% respectively, and those of females were 4.37%, 1.46%, and 0.20% respectively. There was no statistically significant difference in the infection rates between males and females. Educational attainment was inversely associated with infection; in 2010, the highest prevalence was observed among those with primary education or below, whereas in 2021, illiterate or semi-literate individuals showed the highest susceptibility. The occupational distribution of infections in 2010 indicated that retirees (8.33%), farmers(4.86%), and homemakers or unemployed individuals(3.45%)were the most affected. However, in 2021 and 2022, farmers emerged as the predominant occupational group with soil-transmitted nematode infections. Conclusions The infection rate of soil-borne nematodes showed a decreasing trend in Yubei, and the infection species changed from hookworms in 2010 to Ascaris in 2022. Farmers, the elderly, and people with low education levels should continue to be the focus of preventive and control efforts.

Background Silicosis is a fatal form of pulmonary fibrosis caused by the inhalation of silica dust. Although the underlying pathogenesis remains unclear, and the macrophage-mediated immune response plays a central role in its development. Objective To investigate the expression, functional role, and upstream regulatory mechanism of C-C motif chemokine ligand 22 (CCL22) in silica-induced pulmonary fibrosis. Methods Through bioinformatics analysis, we identified CCL22 as a potential key factor in pulmonary fibrosis. We established in vitro models by stimulating human monocytic leukemia cells (THP-1) and peripheral blood mononuclear cell-derived macrophages (PBMC-m) with crystalline silica (CS). The regulation of CCL22 expression by CS was validated using quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Subsequently, a conditioned co-culture system comprising macrophages and lung epithelial cells (BEAS-2B) was developed to evaluate the effects of CCL22 on lung epithelial cell function. Furthermore, the molecular mechanisms underlying CS-induced CCL22 secretion by macrophages were investigated using bioinformatics analysis, Western blot, specific inhibitors, qRT-PCR, and ELISA. Results Bioinformatics analysis identified CCL22 as a key upregulated molecule in pulmonary fibrosis. In vitro experiments confirmed that CS treatment significantly enhanced CCL22 mRNA transcription and protein secretion in THP-1 and PBMC-m cells (P<0. 0001). In the co-culture system, supernatant from CS-stimulated macrophages with stable CCL22 knockdown significantly inhibited the scratch-healing ability and fibrotic process of BEAS-2B cells, and reversed the epithelial-mesenchymal transition (EMT) phenotype compared to the control group. Mechanism studies found that, compared to other transcription factors such as signal transducer and activator of transcription 3 (STAT3) and nuclear factor-κB (NF-κB), the inhibition of of specific protein 1 (SP1) most significantly attenuated the CS-induced upregulation of CCL22. Furthermore, pathway inhibition experiments demonstrated that inhibiting extracellular signal-regulated kinase (ERK) reduced both CCL22 expression and p-SP1. Conversely, SP1 intervention did not affect ERK activation. Conclusion CS promotes CCL22 secretion by macrophages through the Raf/ERK-Sp1 signaling pathway, thereby driving fibrotic changes in pulmonary epithelial cells.

Objective:To investigate the predictive value of pre-infarction angina(PIA)combined with serum lipo-protein-associated phospholipase A2(Lp-PLA2)for no-reflow during primary percutaneous coronary interven-tion(PCI)in elderly patients with new-onset acute ST-segment elevation myocardial infarction(STEMI).Meth-ods:A total of 189 patients who hospitalized because of acute STEMI and underwent primary PCI within 12h in De-partment of Cardiology,Cangzhou People's Hospital between January 2018 and December 2022 were enrolled.Ac-cording to their TIMI blood flow during PCI,the patients were divided into no reflow group(n=42)and normal re-flow group(n=147).The baseline data were compared between two groups.Multivariate Logistic regression analy-sis was used to analyze the risk factors of no-reflow during PCI.The receiver operating characteristic(ROC)curve was plotted to evaluate the predictive value of PIA and Lp-PLA2 for no-reflow.Results:PI A occurred in 73 cases(38.6％),and no reflow occurred in 42 cases(22.2％)during primary PCI.Compared with patients in normal re-flow group,those in no reflow group had significant higher Lp-PLA2[(341.33±98.32)ng/ml vs.(261.95±75.21)ng/ml]and onset to reperfusion time[(7.02±1.28)h vs.(5.14±1.48)h],and significant lower incidence of PIA(23.8％ vs.42.9％)(P＜0.05 or＜0.01).Multivariate Logistic regression analysis showed that Lp-PLA2(OR=1.528,95％CI 1.028～2.030,P＜0.001),onset to reperfusion time(OR=2.602,95％CI 1.848～3.665,P＜0.001)were independent risk factors for no reflow during PCI in elderly STEMI patients,while PIA was an inde-pendent protective factor(OR=0.261,95％CI 0.101～0.671,P=0.005).The area under ROC curve of Lp-PLA2 combined PIA was 0.863(95％CI 0.806～0.909),which was significantly higher than those of Lp-PLA2[0.733(95％CI 0.664～0.794),Z=2.690,P=0.007]and PIA alone[0.609(95％CI 0.535～0.679),Z=5.657,P＜0.001].Conclusion:Pre-infarction angina has an important protective effect on no-reflow in STEMI patients.High Lp-PLA2 and absence of pre-infarction angina at admission may be good predictors of no-reflow during primary PCI in elderly patients with newly-onset acute STEMI,and it contributes to risk stratification of high risk patients.

Objective To evaluate the effectiveness,safety and economy of generic venlafaxine sustained-release capsules and the original drug in clinical practice based on real world clinical data.Methods This is a multicenter,retrospective real-world study.The information of outpatients who used venlafaxine sustained-release capsules in 7 hospitals from October 2021 to October 2022 was collected,including prescription data and laboratory data.They were divided into generic drug group and original drug group.After the baseline level was corrected by propensity score match method,the prescription daily dose,plasma concentration,medication possession ratio,the continuous medication rate for 3,6 and 9 months,dressing change rate,the incidence of adverse reactions,the frequency of drug use,the average daily cost,the annual cost per capita and the proportion of the average annual cost of drugs were compared between the two groups.Results After the baseline level was corrected by propensity score matching method,the prescription daily dose and medication possession ratio(MPR≥0.8)in the generic drug group were higher than that of the original drug group(P＜0.05).There was no statistically difference in plasma concentration between the two groups(P=0.294).The continuous medication rate for 3,6 and 9 months in the generic drug group were statistically higher than those in the original drug group(P＜0.01).The single dressing change rate of the generic drug group was lower than that of the original drug group(P=0.032).There was no significant difference in the rate of secondary dressing change between the two groups(P=1.000).There were no significant differences in the incidence of abnormal ALT,AST,TC,Na,APTT,and PLC between two groups(P＞0.05).The average daily cost of the generic drug group was lower than that of the original drug group.The per capita annual cost of drugs and the proportion of average annual cost of drugs in the generic drug group were significantly lower than those in the original drug group(P＜0.01).Conclusion In the actual clinical diagnosis and treatment,no clinically significant differences in effectiveness and safety were found between the generic venlafaxine sustained-release capsule and the original-patented,while the economic advantages of the generic drug were better than that of the original-patented drug.

Objective:To observe and analyze the ocular clinical features and pathogenic genes of horizontal gaze palsy with progressive scoliosis (HGPPS).Methods:A pedigree study was conducted.Two families with HGPPS diagnosed by ophthalmology examination at Henan Children's Hospital from November 2023 to April 2024 were included, with 3 people from two generations in each family.Medical history and family history of the subjects were inquired.Vision acuity, diopter, anterior segment, intraocular pressure, wide-angle laser scanning ophthalmoscopy, optical coherence tomography, visual evoked potential (VEP), electroretinogram (ERG), ocular B-ultrasound, full spine AP+ lateral view, orbit+ skull+ cervical spine+ thoracic spine+ lumbosacral spine MRI plain scan were performed on the subjects.Whole genomic DNA was extracted from 2 ml of peripheral venous blood collected from the subjects, and gene sequencing was performed using whole exome sequencing (WES) technology.Suspicious pathogenic variant loci were verified by Sanger sequencing, and the pathogenicity of gene variant loci was analyzed according to the ACMG standards and guidelines for the interpretation of sequence variants.This study followed the Declaration of Helsinki.The study protocol was reviewed and approved by the Ethics Committee of Henan Children's Hospital (No.2024-KY-0024).All subjects and guardians signed informed consent forms and were informed of relevant matters before genetic testing.Results:The proband from family 1 was male, 3 years and 2 months old.At the age of 6 months, he was found to have head tilted to the left with a right scoliosis of the spine centered on T11-12 and no obvious abnormalities on VEP and ERG examinations.The proband from family 2 was male, 3 years and 4 months old, with a left scoliosis of the spine centered on T12.Both probands developed horizontal fixation paralysis, unable to rotate eye outward, slightly limited inward rotation, left eye hypertropia, mild horizontal nystagmus, normal vertical eye movement, backward development of major movements, and normal vision, anterior segment and fundus.MRI examination showed that the medulla oblongata was butterfly shaped, and a brainstem fissure could be seen in the center of the medulla oblongata.The genetic testing showed that the proband from family 1 had compound heterozygous variations c. 1054delC/p.Gln352Serfs *90 (M1) in exon 7 and c. 1219G>T/p.Gly407Cys (M2) in exon 8 of ROBO3 gene.The father of the proband carried M1 and the mother of the proband carried M2.The proband from family 2 had compound heterozygous variations c. 1888C>T/p.R630X (M3) in exon 12 and c. 2684C>A/p.A895E (M4) in exon 17 of ROBO3 gene.M1 and M3 were possible pathogenic, and M2 and M4 were of unknown clinical significance, and prediction software predicted M2 and M4 were harmful variations. Conclusions:The main clinical features of two HGPPS pedigree are horizontal fixation paralysis and progressive scoliosis, accompanied by nystagmus and strabismus.MRI shows brainstem fissure in the central medullary area.Four variants are novel variants, which increases the variation spectrum of ROBO3 gene.

Objective To evaluate the application of carbapenem antibiotics in conjunction with hemofil-tration for patients with septic shock and to analyze the impact on serum levels of lncRNA XIST and miRNA-130a.Methods A prospective study was conducted on 80 patients with septic shock treated at our hospital from August 2022 to January 2024.These patients were randomly divided into a control group and an experimental group,each comprising 40 cases.The control group received carbapenem antibiotics,while the experimental group received carbapenem antibiotics in combination with hemofiltration.The clinical outcomes of both groups were evaluated,and comparisons were made regarding their hemodynamic indices[including cardiac output(CO),central venous pressure(CVP),and mean arterial pressure(MAP)],immune function indices[including interleukin-6(IL-6),C-reactive protein(CRP),and tumor necrosis factor-alpha(TNF-α)],oxygen metabolism indices[including blood oxygen saturation(SaO2),blood lactate(LAC),and oxygenation index(PaO2/FiO2)],as well as serum levels of lncRNA XIST and miRNA-130a expression.Results Following treatment,the levels of CO,CVP,MAP,SaO2,PaO2/FiO2,and miRNA-130a were significantly increased,whereas the levels of IL-6,CRP,TNF-α,LAC,and lncRNA XIST were significantly decreased compared to pre-treatment levels(all P<0.05).In comparison with the control group,the experimental group exhibited significantly higher levels of CO,CVP,MAP,and miRNA-130a,as well as significantly lower levels of IL-6,CRP,TNF-α,and lncRNA XIST(all P<0.05).The overall effective rate in the experimental group was significantly higher than that in the control group(χ2=4.501,P<0.05),while no significant difference was observed in the incidence of adverse reactions between the two groups(χ2=0.180,P>0.05).Conclusion Carbapenem antibiotics and hemofiltration therapy can alleviate the symptoms of septic shock patients by downregulating lncRNA XIST expression,upregulating miRNA-130a expression,modulating inflammatory factors,enhancing oxygen metabolism indices,and maintaining hemodynamic stability.

Objective To conduct a visual analysis of the research hotspots and trends of glucocorticoids in the treatment of systemic lupus erythematosus(SLE)both domestically and internationally.Methods The relevant literature from 2004 to 2024 on glucocorticoids use in SLE were retrieved in Web of Science,CNKI,WanFang Data and VIP databases.CiteSpace 6.3.R6 software was used to conduct bibliometric analysis of the number of publications,authors,research institutions,and keywords,and to draw knowledge maps.Results A total of 4,124 literature were retrieved,and 1,491 English literature and 593 Chinese literature were screened and included.The overall trend of English publications was increasing,while the number of Chinese publications declined in recent years.China is the most active country in this research field,but the research among authors and institutions was more dispersed.The results of keyword analysis showed that how to reduce the adverse reactions of glucocorticoids and special populations was the hotspots of research,with keywords such as"rheumatoid arthritis""damage""belimumab""children""pregnancy".Future research trends would be likely to focus on the assessment of treatment efficacy,prolonged remission,and reduction of disease-related injuries,with emergent keywords such as"validation""prolonged remission""treatment efficacy""renal function"Conclusion The use of glucocorticoids in the treatment of SLE continues to be the focus of the research,but with the increasing concern about adverse reactions,the research focus is gradually moving towards optimizing treatment regimens and exploring novel therapies.Future research needs to focus more on individualized treatment,long-term efficacy assessment and clinical application of emerging therapies.
