Cardiovascular diseases (CVDs) tend to affect the young population and are associated with a significant economic burden and psychological distress to the society and families. The physiological and pathological processes underlying CVDs are complex. Ca2+/calmodulin-dependent kinase II (CaMK II), a protein kinase, has multiple biological functions. It participates in multiple pathological processes and plays a central role in the development of CVDs. Based on this, this paper analyzes the structural characteristics and distribution of CaMK II, the mechanism of action of CaMK II, and the relationship between CaMK II and CVDs, including ion channels, ischemia-reperfusion injury, arrhythmias, myocardial hypertrophy, cardiotoxicity, hypertension, and dilated cardiomyopathy. Given the different regulatory mechanisms of different isoforms of CaMK II, the clinical use of specific targeted inhibitors or novel compounds should be evaluated in future research to provide new directions.

心血管疾病(CVDs)多发于年轻人群,给社会和家庭带来沉重的经济负担和心理压力。心血管疾病的生理和病理过程十分复杂。Ca2+/钙调蛋白依赖性激酶 II(CaMK II)是一种蛋白激酶,具有多种生物学功能。它参与多种病理过程,在心血管疾病的发生发展中起着核心作用。基于此,本文分析了 CaMK II 的结构特点和分布、CaMK II 的作用机制,以及 CaMK II 与心血管疾病(包括离子通道、缺血再灌注损伤、心律失常、心肌肥厚、心脏毒性、高血压和扩张型心肌病)之间的关系。鉴于 CaMK II 不同异构体的调控机制不同,在未来的研究中应评估特定靶向抑制剂或新型化合物的临床应用,以提供新的研究方向。

Purpose: This study aimed to isolate and characterize palmatine from Fibraurea tinctoria Lour stems, quantify its content, and determine its antioxidant and antidiabetic activities.
Patients and Methods: Palmatine was isolated from the methanol extract of Fibraurea tinctoria Lour stems by silica gel column chromatography. Structural elucidation of the isolated compounds was performed using spectral data analysis and comparison with the literature. High-Performance Liquid Chromatography (HPLC) was used to quantitatively determine palmatine in the crude methanol extract and fractions. The DPPH and non-enzymatic SOD mimic methods were used to assess the antioxidant activity of the methanol extract, fractions, and isolated compounds. The antidiabetic activity was evaluated in silico by the molecular docking method of alpha-glucosidase and DPP-IV enzymes. Palmatine was used as a test ligand and was compared with berberine and its native ligand or standard compounds.
Results: The isolated compound was identified as palmatine. Quantification of palmatine compound by HPLC showed that palmatine was found in the extract and all fractions. In the in vitro antioxidant activity test using the DPPH method, fraction 4 showed the highest activity, with an IC50 value of 91 ppm. In contrast, using the non-enzymatic SOD mimic method, the methanol extract, fraction 5, and isolated compound (palmatine) exhibited very strong antioxidant activity, with IC50 values of 18, 20, and 28 ppm, respectively. The in silico antidiabetic activity of palmatine is thought to have the potential to inhibit these two enzymes.
Conclusion: These results showed that Fibraurea tinctoria Lour stems have potential as an antioxidant and antidiabetic agent. Further research on phytochemical and pharmacological is required to validate the use of this plant species for the treatment of various diseases, especially diabetes mellitus.

Keywords: Fibraurea tinctoria Lour, berberine, palmatine, antioxidant, antidiabetic

Purpose: This study aimed to investigate patients’ expectative pain of spinal anesthesia puncture and anxiety pre-anesthesia, and to examine the effect of lidocaine-prilocaine cream and remimazolam prior to spinal anesthesia puncture on pain relief and anxiety release.
Methods: Patients undergoing spinal anesthesia were divided into control, lidocaine-prilocaine cream, and lidocaine-prilocaine cream with remimazolam groups. A questionnaire consisting of The Amsterdam Preoperative Anxiety and Information Scale (APAIS) and patient’s concerns and Visual Analog Scale (VAS) was used to evaluate patient’s anxiety and pain. The primary outcomes were differences in VAS and anxiety scores. Patient’s spinal anesthesia-related concerns, advent events and hemodynamic index were also recorded.
Results: The expected spinal anesthesia puncture pain was 5.34± 0.27 and anxiety scores before spinal anesthesia was 10.88 ± 0.64. A statistically significant positive correlation of 31.3% was detected between VAS and APAIS scores (r = 0.313; P=0.003). The VAS score at the time of puncture decreased by 29.7% (3.78± 0.40, P=0.001) in lidocaine-prilocaine cream group and 29.2% (3.75± 0.39, P=0.001) in lidocaine-prilocaine cream with remimazolam group compared with the expected VAS score. Lidocaine-prilocaine cream combined with or without remimazolam reduced the percentage of moderate pain (21.4% and 31.3% vs 50.0%, P=0.0001) and increased mild pain (60.7% vs 59.4% vs 22.7%, P=0.03). Anxiety score in lidocaine-prilocaine cream group was reduced by 2.84 (8.04± 0.76 vs 10.88 ± 0.46, P=0.05) when compared with pre-anesthesia. Concerns about postoperative pain (P=0.03) and fear of the needle or intervention (P=0.000) both decreased post-anesthesia among groups.
Conclusion: Approximately half of the patients scheduled for spinal anesthesia experienced a moderate level of preoperative anxiety. The patient’s pain expectation from the spinal anesthesia puncture was moderate, which was higher than the actual pain. Lidocaine-prilocaine cream with or without remimazolam sedative before spinal anesthesia puncture reduced the patient’s pain and anxiety scores after surgery.

Keywords: preoperative anxiety, APAIS, spinal anesthesia, lidocaine-prilocaine, remimazolam
目的:本研究旨在调查患者对脊髓麻醉穿刺的预期疼痛和麻醉前焦虑,并探讨脊髓麻醉穿刺前使用利多卡因-阿鲁卡因乳膏和雷马唑仑对缓解疼痛和释放焦虑的影响:方法:将接受脊髓麻醉的患者分为对照组、利多卡因-阿鲁卡因乳膏组和利多卡因-阿鲁卡因乳膏加瑞马唑仑组。采用由阿姆斯特丹术前焦虑和信息量表(APAIS)、患者关注点和视觉模拟量表(VAS)组成的问卷来评估患者的焦虑和疼痛。主要结果是 VAS 和焦虑评分的差异。此外,还记录了患者与脊髓麻醉相关的担忧、突发事件和血液动力学指数:结果:预期脊髓麻醉穿刺疼痛为(5.34±0.27)分,脊髓麻醉前焦虑评分为(10.88±0.64)分。VAS评分和APAIS评分之间存在31.3%的统计学意义上的正相关(r=0.313;P=0.003)。与预期的 VAS 评分相比,利多卡因-阿鲁洛卡因乳膏组穿刺时的 VAS 评分下降了 29.7%(3.78± 0.40,P=0.001),利多卡因-阿鲁洛卡因乳膏加瑞咪唑仑组下降了 29.2%(3.75± 0.39,P=0.001)。利多卡因-普鲁卡因乳膏联合或不联合雷马唑仑可降低中度疼痛的比例(21.4% 和 31.3% vs 50.0%,P=0.0001),增加轻度疼痛的比例(60.7% vs 59.4% vs 22.7%,P=0.03)。与麻醉前相比,利多卡因-普鲁卡因乳膏组的焦虑评分降低了 2.84(8.04±0.76 vs 10.88±0.46,P=0.05)。对术后疼痛的担忧(P=0.03)和对针头或干预的恐惧(P=0.000)在麻醉后各组间均有所下降:结论:约有一半计划接受脊髓麻醉的患者在术前有中度焦虑。患者对脊髓麻醉穿刺疼痛的预期为中度,高于实际疼痛。在脊髓麻醉穿刺前使用利多卡因-阿鲁洛卡因乳膏或不使用雷马唑仑镇静剂可降低患者术后的疼痛和焦虑评分。 关键词:术前焦虑;APAIS;脊髓麻醉;利多卡因-阿鲁洛卡因;雷马唑仑

Abstract: Immunoglobulin A nephropathy (IgAN) is a chronic, immune-mediated kidney disease characterized by the deposition of galactose-deficient immunoglobulin A1 (Gd-IgA1) in the kidneys. Excess Gd-IgA1 production in patients with IgAN is located within the mucosa-associated lymphoid tissue, particularly within the lamina propria in the distal ileum. Nefecon® is a targeted-release formulation of the corticosteroid budesonide, which became the first treatment approved by the US Food and Drug Administration (FDA; brand name, TARPEYO®) and European Medicines Agency (EMA; KINPEYGO®) for patients with primary IgAN at risk of rapid disease progression, after demonstrating clinically significant reduction of proteinuria in an interim analysis of the Phase III NefIgArd trial. After showing a significant reduction in estimated glomerular filtration rate decline in the full 2-year analysis of the trial, Nefecon was granted full approval by the FDA to reduce the loss of kidney function. Nefecon was specifically designed to deliver budesonide to the distal ileum, selectively targeting excess Gd-IgA1 production in the gut-associated lymphoid tissue. In this review, we describe the properties of Nefecon and the evidence to date that confirms its localized treatment effect. We also present unpublished evidence from Phase I trials investigating the pharmacokinetics and cortisol suppression effects of Nefecon in healthy participants. These studies demonstrated that Nefecon has a distinct pharmacokinetic profile from other budesonide products, allowing for targeted, localized action in the distal ileum. When considered alongside existing clinical trial data showing the effect of Nefecon on gut-associated biomarkers, available evidence indicates that Nefecon has a selective immunomodulatory mechanism of action and a direct disease-modifying effect in patients with IgAN, while having low systemic exposure and adverse effects.

摘要:免疫球蛋白 A 肾病(IgAN)是一种免疫介导的慢性肾病,其特征是半乳糖缺陷免疫球蛋白 A1(Gd-IgA1)在肾脏沉积。IgAN患者体内过多的Gd-IgA1产生于粘膜相关淋巴组织,尤其是回肠远端固有层。Nefecon®是皮质类固醇布地奈德的靶向释放制剂,在III期NefIgArd试验的中期分析中显示蛋白尿临床显著减少,因此成为美国食品药品管理局(FDA;品牌名TARPEYO®)和欧洲药品管理局(EMA;KINPEYGO®)批准的首款治疗药物,用于治疗面临疾病快速进展风险的原发性IgAN患者。在该试验的两年期分析中,估计肾小球滤过率的下降明显减少,因此,FDA 批准 Nefecon 用于减少肾功能损失。Nefecon 专门设计用于将布地奈德输送到回肠远端,选择性地针对肠道相关淋巴组织中过量 Gd-IgA1 的产生。在本综述中,我们介绍了 Nefecon 的特性以及迄今为止证实其局部治疗效果的证据。我们还介绍了在健康参与者中调查奈非康的药代动力学和皮质醇抑制效果的 I 期试验中未发表的证据。这些研究表明,奈非康具有不同于其他布地奈德产品的药代动力学特征,可在回肠远端发挥有针对性的局部作用。现有证据表明,奈非康有选择性免疫调节作用机制,对IgAN患者有直接的疾病调节作用,同时全身暴露和不良反应较低。

Abstract: Insulin resistance (IR) is a complex pathological condition central to metabolic diseases such as type 2 diabetes mellitus (T2DM), cardiovascular disease, non-alcoholic fatty liver disease, and polycystic ovary syndrome (PCOS). This review evaluates the impact of lipids on insulin resistance (IR) by analyzing findings from human and animal studies. The articles were searched on the PubMed database using two keywords: (1) “Role of Lipids AND Insulin Resistance AND Humans” and (2) “Role of Lipids AND Insulin Resistance AND Animal Models”. Studies in humans revealed that elevated levels of free fatty acids (FFAs) and triglycerides (TGs) are closely associated with reduced insulin sensitivity, and interventions like metformin and omega-3 fatty acids show potential benefits. In animal models, high-fat diets disrupt insulin signaling and increase inflammation, with lipid mediators such as diacylglycerol (DAG) and ceramides playing significant roles. DAG activates protein kinase C, which eventually impairs insulin signaling, while ceramides inhibit Akt/PKB, further contributing to IR. Understanding these mechanisms is crucial for developing effective prevention and treatment strategies for IR-related diseases.

Keywords: high-fat diet, insulin resistance, lipid profile, type 2 diabetes mellitus
摘要:胰岛素抵抗(IR)是一种复杂的病理状态,是 2 型糖尿病(T2DM)、心血管疾病、非酒精性脂肪肝和多囊卵巢综合征(PCOS)等代谢性疾病的核心。本综述通过分析人类和动物研究结果,评估血脂对胰岛素抵抗(IR)的影响。文章在 PubMed 数据库中使用两个关键词进行搜索:(1)"血脂的作用、胰岛素抵抗、人类";(2)"血脂的作用、胰岛素抵抗、动物模型"。对人类的研究表明,游离脂肪酸(FFAs)和甘油三酯(TGs)水平升高与胰岛素敏感性降低密切相关,二甲双胍和欧米伽-3 脂肪酸等干预措施显示出潜在的益处。在动物模型中,高脂饮食会破坏胰岛素信号传导并增加炎症反应,其中二酰甘油(DAG)和神经酰胺等脂质介质发挥了重要作用。DAG 会激活蛋白激酶 C,最终损害胰岛素信号,而神经酰胺会抑制 Akt/PKB,进一步导致 IR。了解这些机制对于制定与 IR 相关疾病的有效预防和治疗策略至关重要。

Introduction: This comprehensive study investigated the therapeutic potential of α-asarone in mitigating myocardial oxidative damage, primarily induced by hexavalent chromium (Cr(VI)) exposure in mice.
Methods: In this experiment, 24 mice were divided into four groups to assess the cardioprotective role of α-asarone. The study focused on two treatment groups, receiving 25 mg and 50 mg of α-asarone, respectively. These groups were compared against a control group subjected to Cr(VI) without α-asarone treatment, and a normal control negative group. The key biochemical parameters evaluated included serum levels of Creatine Kinase-MB (CK-MB) and Troponin I, markers indicative of myocardial damage. Additionally, the levels of Malondialdehyde (MDA) were measured to assess lipid peroxidation, alongside the evaluation of key inflammatory biomarkers in cardiac tissue homogenates, such as Tumor Necrosis Factor-α (TNF-α) and Interleukin-1β (IL-1β). Results Remarkably, α-asarone treatment resulted in a significant reduction in these markers compared to the control group. The treatment also elevated the activity of cardinal antioxidant enzymes like catalase (CAT) and superoxide dismutase (SOD), and reduced the glutathione (GSH). Furthermore, a notable upregulation of Peroxisome Proliferator-Activated Receptor Gamma (PPAR-γ) in cardiac tissue homogenates was observed, highlighting a potential pathway through which α-asarone exerts its protective effects. Histopathological analysis of cardiac tissues revealed that α-asarone ameliorated the structural lesions induced by Cr(VI). The study thus provides substantial evidence that α-asarone ameliorates Cr(VI)-induced cardiotoxicity through a multifaceted approach. It enhances cardiac enzyme function, modulates free radical generation, improves antioxidant status, and mitigates histopathological damage in cardiac tissues. Given these findings, α-asarone emerges as a promising agent against Cr(VI)-induced myocardial injury.
Purpose: This study paves the way for further research into the cardioprotective properties of α-asarone and its potential application in clinical settings by specifically exploring the protective efficacy of α-asarone against Cr(VI)-induced cardiotoxicity and delineating the underlying biochemical and molecular mechanisms involved.

简介:这项综合研究探讨了α-asarone在减轻主要由六价铬(Cr(VI))暴露诱发的小鼠心肌氧化损伤方面的治疗潜力:本实验将 24 只小鼠分为四组,以评估 α-asarone 的心脏保护作用。研究的重点是两个治疗组,分别接受 25 毫克和 50 毫克的 α-asarone 治疗。这些治疗组与接受六价铬治疗但未接受α-asarone治疗的对照组和正常对照阴性组进行了比较。评估的主要生化参数包括血清中肌酸激酶-MB(CK-MB)和肌钙蛋白 I 的水平,它们是心肌损伤的标志物。此外,还测量了丙二醛(MDA)水平,以评估脂质过氧化反应,同时评估了心脏组织匀浆中的主要炎症生物标志物,如肿瘤坏死因子-α(TNF-α)和白细胞介素-1β(IL-1β)。结果 值得注意的是,与对照组相比,α-asarone 治疗显著降低了这些指标。治疗还提高了过氧化氢酶(CAT)和超氧化物歧化酶(SOD)等主要抗氧化酶的活性,并降低了谷胱甘肽(GSH)。此外,还观察到心脏组织匀浆中的过氧化物酶体激活受体 Gamma(PPAR-γ)显著上调,这凸显了 α-asarone 发挥保护作用的潜在途径。心脏组织的组织病理学分析表明,α-asarone 可改善六价铬引起的结构性病变。因此,这项研究提供了大量证据,证明α-asarone 可通过多方面的方法改善六价铬诱导的心脏毒性。它能增强心肌酶的功能,调节自由基的生成,改善抗氧化状态,减轻心脏组织的组织病理学损伤。鉴于这些研究结果,α-asarone 成为了一种很有前景的抗六价铬诱导的心肌损伤的药物。目的:本研究通过具体探讨α-asarone对六价铬诱导的心脏毒性的保护作用,并阐明其潜在的生化和分子机制,为进一步研究α-asarone的心脏保护特性及其在临床中的潜在应用铺平了道路。 关键词:α-asarone;铬;小鼠;心脏毒性;氧化应激;组织病理学研究

Purpose: Alisma orientale (AO, Alisma orientale (Sam). Juzep) has been widely employed for the treatment of macular edema (ME) in traditional Chinese medicine due to its renowned water-relief properties. Nonetheless, the comprehensive investigation of AO in alleviating ME remained unexplored. This study aims to identify the active components of AO that target the eye and investigate its pharmacological effects and mechanisms on ME.
Methods: The study commenced with UPLC-Triple-TOF/MS analysis to identify the primary constituents of AO. Zebrafish eye tissues were then analyzed after a five-day administration of AO to detect absorbed components and metabolites. Subsequently, network pharmacology, molecular docking, and molecular dynamics simulations were employed to predict the mechanisms of ME treatment via biological target pathways. In vivo experiments were conducted to corroborate the pharmacological actions and mechanisms.
Results: A total of 7 compounds, consisting of 2 prototype ingredients and 5 metabolites (including isomers), were found to traverse the blood-eye barrier and localized within eye tissues. Network pharmacology results showed that AO played a role in the treatment of ME mainly by regulating the pathway network of PI3K-AKT and MAPK with TNF-α centered. Computational analyses suggested that 11-dehydro-16-oxo-24-deoxy-alisol A, a metabolite of alisol A, mitigates edema through TNF-α inhibition. Furthermore, zebrafish fundus confocal experiments and HE staining of eyes confirmed the attenuating effects of alisol A on fundus angiogenesis and ocular edema, representing the first report of AO’s ME-inhibitory effects.
Conclusion: In this study, computational analyses with experimental validation were used to understand the biological activity and mechanism of alisol A in the treatment of ME. The findings shed light on the bioactive constituents and pharmacological actions of AO, offering valuable insights and a theoretical foundation for its clinical application in managing ME.

Background: Multidrug-resistant Gram-negative bacteria (MDR-GNB) are becoming increasingly common around the world, with carbapenems frequently serving as a last resort but being threatened by the growing incidence of carbapenemase-producing bacteria. Ceftazidime-avibactam (CAZ/AVI) is a potential agent against MDR-GNB but with limited clinical experience, particularly in critically ill immunosuppressed children.
Methods: This study analyzed the use of CAZ/AVI as salvage treatment in severely infected immunosuppressed children from September 2019 to July 2022. Patients with confirmed GNB infection who received CAZ/AVI were matched with patients who received other antibiotics.
Results: Twenty-five critically ill immunosuppressed children treated with CAZ/AVI were included. The majority had hematologic diseases. All patients presented with sepsis in all 30 courses. Septic shock presented in 36.7% of these courses. The primary sites of infection included bloodstream infection (20.0%), skin and skin structure infection (20.0%), intra-abdominal infection (13.3%) and hospital-acquired pneumonia (10.0%). Twelve of the 25 (48.0%) patients had positive microbiological cultures, mainly Pseudomonas aeruginosa and Klebsiella pneumoniae, including 5 carbapenem-resistant GNB-infected cases. Fifteen (50.0%) courses presented clinical improvement. For the initial course of each patient, the clinical response rate of the GNB recovered group was significantly higher than that of the group without GNB recovery (66.7% vs 23.1%, P = 0.047). The 14-day and 30-day mortality rates were 24.0% and 28.0%, respectively, which were significantly correlated with the absence of GNB recovery (P = 0.004 and 0.024, respectively) and hospital-acquired pneumonia as the primary site of infection (P = 0.001 and 0.006, respectively). There was no significant difference in major outcomes between patients who received CAZ/AVI and matched patients who received other antibiotics.
Conclusion: CAZ/AVI could be considered a salvage strategy for immunosuppressed children with confirmed GNB infection. Caution should be taken when CAZ/AVI is applied to these patients in the absence of GNB recovery.

背景:耐多药革兰氏阴性菌(MDR-GNB)在全球范围内越来越常见,碳青霉烯类常常是最后的手段,但也受到了产碳青霉烯酶细菌日益增多的威胁。头孢唑肟-阿维巴坦(CAZ/AVI)是一种抗MDR-GNB的潜在药物,但临床经验有限,尤其是在重症免疫抑制儿童中:本研究分析了2019年9月至2022年7月期间在重症感染免疫抑制儿童中使用CAZ/AVI作为挽救治疗的情况。接受 CAZ/AVI 治疗的确诊 GNB 感染患者与接受其他抗生素治疗的患者进行配对:纳入了 25 名接受 CAZ/AVI 治疗的重症免疫抑制儿童。大多数患儿患有血液病。所有患者在全部 30 个疗程中均出现败血症。其中36.7%的疗程出现了败血症性休克。主要感染部位包括血流感染(20.0%)、皮肤和皮肤结构感染(20.0%)、腹腔内感染(13.3%)和医院获得性肺炎(10.0%)。25 名患者中有 12 名(48.0%)微生物培养呈阳性,主要是铜绿假单胞菌和肺炎克雷伯菌,其中包括 5 例耐碳青霉烯类的 GNB 感染病例。15个疗程(50.0%)的临床症状有所改善。在每位患者的初始疗程中,GNB恢复组的临床反应率明显高于未恢复组(66.7% vs 23.1%,P = 0.047)。14 天和 30 天的死亡率分别为 24.0% 和 28.0%,这与无 GNB 恢复(P = 0.004 和 0.024,分别为 0.004 和 0.024)和医院获得性肺炎作为主要感染部位(P = 0.001 和 0.006,分别为 0.001 和 0.006)显著相关。接受 CAZ/AVI 治疗的患者与接受其他抗生素治疗的患者在主要结果上没有明显差异:结论:CAZ/AVI可作为免疫抑制儿童确诊GNB感染的挽救策略。结论:CAZ/AVI 可被视为确诊 GNB 感染的免疫抑制儿童的挽救策略,但在 GNB 未恢复的情况下对这些患者使用 CAZ/AVI 时应谨慎。

Background: This study explored the effects of different doses of remimazolam tosilate (RT) and propofol combined with remifentanil anesthesia on hemodynamic and inflammatory responses in patients undergoing laparoscopic surgery.
Subjects and Methods: Ninety patients with a BMI of less than 35 kg/m², classified as ASA II–III and scheduled for laparoscopic surgery, were enrolled in this study. Patients were divided into three groups: low-dose RT group (A), high-dose RT group (B), and propofol group (C). The changes in hemodynamic indices such as SBP, DBP, HR, MAP, and inflammatory response indices such as IL-6, SAA, CRP, and PCT, along with extubation time and doses of sufentanil, remifentanil, urapidil, and phenylephrine, were compared among the three groups.
Results: There were no statistically significant differences in extubation time, doses of sufentanil and remifentanil, or the usage rates and average doses of urapidil and phenylephrine between the three groups. The average dose of phenylephrine in group A was lower than in group B and group C, with a statistically significant difference. There were no statistically significant differences among the groups in SBP, DBP, HR, and MAP from T0 to T2, nor in IL-6, SAA, CRP, or PCT levels.
Conclusion: Using RT for induction and maintenance of anesthesia in laparoscopic surgery ensures stable hemodynamic and inflammatory responses in patients. Low-dose RT may reduce the usage rate and dose of vasopressors such as phenylephrine during surgery.

背景:本研究探讨了不同剂量的替磺酸雷马唑仑(RT)和丙泊酚联合瑞芬太尼麻醉对腹腔镜手术患者血流动力学和炎症反应的影响:本研究招募了 90 名体重指数小于 35 kg/m²、ASA 分级为 II-III 级并计划接受腹腔镜手术的患者。患者被分为三组:低剂量 RT 组(A)、高剂量 RT 组(B)和异丙酚组(C)。比较三组患者的 SBP、DBP、HR、MAP 等血流动力学指标和 IL-6、SAA、CRP、PCT 等炎症反应指标的变化,以及拔管时间和舒芬太尼、瑞芬太尼、乌拉地尔、苯肾上腺素的剂量:三组患者的拔管时间、舒芬太尼和瑞芬太尼的剂量、乌拉地尔和苯肾上腺素的使用率和平均剂量均无统计学差异。A 组的苯肾上腺素平均剂量低于 B 组和 C 组,差异有统计学意义。从 T0 到 T2,各组之间的 SBP、DBP、HR 和 MAP,以及 IL-6、SAA、CRP 或 PCT 水平均无明显统计学差异:结论:在腹腔镜手术中使用 RT 诱导和维持麻醉可确保患者血流动力学和炎症反应的稳定。小剂量 RT 可减少手术中血管加压药(如苯肾上腺素)的使用率和剂量。

Purpose: Oral drug administration is the most common and convenient route, offering good patient compliance but drug solubility limits oral applications. Celecoxib, an insoluble drug, requires continuous high-dose oral administration, which may increase cardiovascular risk. The nanostructured lipid carriers prepared from drugs and lipid excipients can effectively improve drug bioavailability, reduce drug dosage, and lower the risk of adverse reactions.
Methods: In this study, we prepared hyaluronic acid-modified celecoxib nanostructured lipid carriers (HA-NLCs) to improve the bioavailability of celecoxib and reduce or prevent adverse drug reactions. Meanwhile, we successfully constructed a set of FDA-compliant biological sample test methods to investigate the pharmacokinetics of HA-NLCs in rats.
Results: The pharmacokinetic analysis confirmed that HA-NLCs significantly enhanced drug absorption, resulting in an AUC0-t 1.54 times higher than the reference formulation (Celebrex®). Moreover, compared with unmodified nanostructured lipid carriers (CXB-NLCs), HA-NLCs enhance the retention time and improve the drug’s half-life in vivo.
Conclusion: HA-NLCs significantly increased the bioavailability of celecoxib. The addition of hyaluronic acid prolonged the drug’s in vivo duration of action and reduced the risk of cardiovascular adverse effects associated with the frequent administration of oral celecoxib.

目的:口服给药是最常见、最方便的给药途径,患者依从性好,但药物溶解性限制了口服应用。塞来昔布是一种不溶性药物,需要连续大剂量口服给药,可能会增加心血管风险。利用药物和脂质辅料制备的纳米结构脂质载体可有效提高药物的生物利用度,减少药物用量,降低不良反应风险:本研究制备了透明质酸修饰的塞来昔布纳米结构脂质载体(HA-NLCs),以提高塞来昔布的生物利用度,减少或预防药物不良反应。同时,我们成功构建了一套符合FDA标准的生物样本测试方法,研究了HA-NLCs在大鼠体内的药代动力学:药代动力学分析证实,HA-NLCs 能显著促进药物吸收,其 AUC0-t 是参比制剂(Celebrex®)的 1.54 倍。此外,与未改性的纳米结构脂质载体(CXB-NLCs)相比,HA-NLCs能延长药物在体内的保留时间并改善药物的半衰期:结论:HA-NLCs能明显提高塞来昔布的生物利用度。结论:HA-NLCs能明显提高塞来昔布的生物利用度,透明质酸的加入延长了药物在体内的作用时间,降低了频繁口服塞来昔布引起心血管不良反应的风险。关键词:纳米结构脂质载体、塞来昔布、HPLC-MS/MS、药代动力学

Celecoxib, an insoluble drug, requires continuous high-dose oral administration, which may increase cardiovascular risk. The nanostructured lipid carriers prepared from drugs and lipid excipients can effectively improve drug bioavailability, reduce drug dosage, and lower the risk of adverse reactions.<br/><strong>Methods:</strong> In this study, we prepared hyaluronic acid-modified celecoxib nanostructured lipid carriers (HA-NLCs) to improve the bioavailability of celecoxib and reduce or prevent adverse drug reactions.
