目的   探讨肺癌伴癌性疼痛患者心理僵化现状及其影响因素，为临床制定改善患者心理僵化的针对性干预措施以及提升患者生活质量提供参考依据。方法   采用便利抽样法，选取2023年10月—12月期间焦作市某三级甲等医院收治的肺癌伴癌性疼痛患者为研究对象，采用一般资料调查问卷、疼痛心理僵化量表（PIPS）、简易疾病感知问卷（BIPQ）、家庭功能问卷（APGAR）进行调查，采用Pearson相关性分析肺癌伴癌性疼痛患者心理僵化与疾病感知、家庭功能的关系。采用多元线性回归分析肺癌伴癌性疼痛患者心理僵化的影响因素。结果   本次研究共发放问卷152份，回收有效问卷150份，有效回收率为98.68%。150例肺癌伴癌性疼痛患者心理僵化量表总分为（61.66±2.85）分，回避型经验维度得分为（45.52±1.97）分，认知融合维度得分为（19.74±1.59）分。不同文化程度、家庭人均月收入、疼痛程度的肺癌伴癌性疼痛患者心理僵化得分比较，差异有统计学意义（P＜0.05）。Pearson相关性分析结果显示：肺癌伴癌性疼痛患者心理僵化总分、经验性回避维度得分、认知融合维度得分与疾病感知得分均呈正相关关系（P＜0.001），与家庭功能得分均呈负相关关系（P＜0.001）。多元线性回归结果显示：文化程度、家庭人均月收入、疾病感知、家庭功能是肺癌伴癌性疼痛患者心理僵化的影响因素（P＜0.05），可解释肺癌伴癌性疼痛患者心理僵化43.9%的变异度。结论   肺癌伴癌性疼痛患者心理僵化处于较高水平，且受到文化程度、家庭人均月收入、疾病感知和家庭功能的影响，临床医护人员可从疾病感知、家庭支持等角度出发，采用认知干预、同伴支持等方法，加强对患者的健康教育，以缓解其对疾病的负性认知，从而缓解心理僵化，促进身心健康恢复。

       目的   探讨营养评估及炎症因子水平对非霍奇金淋巴瘤（NHL）患者化学治疗（化疗）后感染及平均住院日的影响。方法   回顾性分析接受R-CHOP治疗的NHL患者95例。通过受试者工作特征（ROC）曲线确定患者主观整体营养评估（PG-SGA）预测患者化疗后感染的界值。将患者分为PG-SGA＜4组与PG-SGA≥4组，比较两组间营养及炎症相关指标的差异。采用单因素与多因素回归分析NHL患者化疗后感染及平均住院日延长的危险因素。结果  ROC曲线显示PG-SGA为3.5时，约登指数最大，预测NHL患者化疗后感染灵敏度为92%，特异度为11.1%。PG-SGA≥4组患者平均年龄、国际预后指数（IPI）及Ann arbor Ⅲ~Ⅳ期比例均高于PG-SGA＜4组（P＜0.05）。与PG-SGA＜4组相比，PG-SGA≥4组患者白介素6（IL-6）及中性粒细胞与淋巴细胞比值（NLR）明显升高，且化疗后感染率及平均住院日≥5 d比例高于对照组（P＜0.05）；与对照组相比，PG-SGA＜4组患者前白蛋白、白蛋白和血红蛋白水平升高（P均＜0.05）。多因素回归分析显示，PG-SGA≥4及合并糖尿病是NHL患者化疗后感染率的独立危险因素（P均＜0.05）。白蛋白低于35 g/L及合并化疗后感染是NHL患者平均住院日延长的独立危险因素（P均＜0.05）。结论   基于PG-SGA的营养评估及炎症因子分析对NHL患者化疗后感染及平均住院日的预测具有临床指导意义。

脓毒症当前仍然是全球范围内重要的医疗卫生问题,其对世界公共卫生及患者安全带来重大威胁。脓毒症是指宿主对感染反应失调引起的危及生命的器官功能障碍, 其发病率和病死率均极高,是临床重症医学中的重大挑战。在脓毒症病情的进展过程中, 可出现组织灌注不足、血流动力学不稳定等变化, 从而导致多器官功能受损,而心脏是常见的被累及的重要靶器官之一, 这种由脓毒症所导致的不同程度的心肌损伤, 被称为“脓毒性心肌病”, 其发生和发展机制复杂多样, 涉及循环心肌抑制因素、心肌自身因素及自主神经失调等多个方面。文章综述了脓毒症患者发生心肌损伤的高危因素, 以期为临床治疗和预防提供参考。

Sepsis currently remains an important global healthcare issue, and a major threat to world public health and patient safety．Sepsis is a life-threatening organ dysfunction caused by dysregulation of the host response to infection, with extremely high morbidity and mortality,which is a major challenge in clinical critical care medicine．During the progression of sepsis, changes such as inadequate tissue perfusion and haemodynamic instability may occur, leading to impairment of multiple organ functions, while the heart is one of the commonly involved vital target organs, and the varying degree of myocardial damage caused by sepsis is known as “septic cardiomyopathy”．The mechanisms of its occurrence and development are complex and diverse, involving circulating myocardial inhibitory factors, myocardial auto-factors, and autonomic dysregulation．In this paper, we review the high-risk factors for myocardial injury in septic patients, providing a reference for clinical treatment and prevention.

Objective To study the relevant risk factors of neonatal hypoglycemia．Methods A retrospective analysis was conducted on the clinical data of 570 newborns in neonatal pediatrics,including 190 cases in the neonatal hypoglycemia group and 380 cases in the normal blood glucose group．Logistic regression analysis was used to analyze the risk factors related to neonatal hypoglycemia．Results Single factor Logistic regression analysis showed that neonatal weight loss,premature,neonatal respiratory failure,neonatal respiratory distress,neonatal infection,the mother’s age of delivery,multipara,cesarean section,twins,pregnancy diabetes,pregnancy hypertension were the risk factors for neonatal hypoglycemia,all of which had statistical significance（all P<0.05）．In multivariate Logistic regression analysis,premature（OR=2.115,95% CI：1.186-3.772）and cesarean section（OR=6.92,95% CI：4.202-11.397）were risk factors for neonatal hypoglycemia（both P<0.05）．Conclusions Premature and cesarean section are risk factors for the occurrence of neonatal hypoglycemia in the local area．Timely identification and treatment of neonatal hypoglycemia based on risk factors,providing timely postpartum nursing guidance for newborns,can reduce the occurrence of neonatal hypoglycemia．

目的 探讨电子计算机断层扫描（CT）增强碘对比剂急性不良反应发生及影响因素分析。方法 选取天津市肿瘤医院空港医院2020年10月—2023年10月收治的100例行CT增强出现碘对比剂急性不良反应的患者进行回顾性分析,将其分为观察组,另选取同期在我院行CT增强检查未发生不良反应的100例患者作为对照组。分析观察组患者碘对比剂急性不良反应情况,对比两组患者临床资料及碘对比剂注射情况,以急性不良反应作为因变量（发生急性不良反应=1,未发生急性不良反应=0）纳入Logistic回归模型,分析CT增强碘对比剂急性不良反应发生的独立影响因素。结果 100例发生碘对比剂急性不良反应的患者中轻度65例（65.00%）,中度34例（34.00%）,重度1例（1.00%）;观察组与对照组性别、年龄、体质指数（BMI）、高血压史、糖尿病史、心功能不全史、甲状腺功能亢进史、冠状动脉粥样硬化性心脏病史、碘对比剂使用史、食物过敏史对比差异无统计学意义（P>0.05）,观察组与对照组哮喘史（9.00% vs 2.00%）、肾功能不全史（13.00% vs 3.00%）、碘对比剂不良反应发生史（21.00 % vs 2.00%）、花粉过敏史（12.00% vs 4.00%）、药物过敏史（26.00% vs 7.00%）及其他过敏史（10.00 % vs 2.00%）,对比差异有统计学意义（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）;观察组与对照组碘对比剂剂量对比差异无统计学意义（P>0.05）,观察组与对照组碘对比剂注射速度（<3 mL/min为55.00% vs 69.00%;≥3 mL/min为45.00% vs 31.00%）、碘对比剂类型（碘克沙醇为34.00% vs 34.00%,碘佛醇为47.00% vs 30.00%,碘海醇为19.00% vs 36.00%）对比差异有统计学意义（χ²=4.160,P=0.041;χ²=9.010,P=0.011）;肾功能不全史、碘对比剂不良反应发生史、药物过敏史、其他过敏史、碘对比剂注射速度为发生碘对比剂急性不良反应的影响因素（P<0.05）。结论 CT增强碘对比剂急性不良反应多以轻度为主,且以往合并肾功能不全、碘对比剂不良反应发生史、药物过敏史、其他过敏史、碘对比剂注射速度过高可能为碘对比剂不良反应发生的影响因素。

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．
