    造影剂肾病(CIN)是急性心肌梗死(AMI)经皮冠状动脉介入治疗的常见术后并发症。氢溴酸山莨菪碱是一种生物碱,已证明在改善微循环方面具有功效。这项荟萃分析旨在评估山莨菪碱对AMI经皮冠状动脉介入治疗(PCI)患者的肾脏保护作用。
    PubMed,Embase,科克伦图书馆,Scopus,和临床试验从开始到2024年1月进行了随机对照试验(RCT)比较山莨菪碱预防CIN的疗效。感兴趣的结果包括CIN的发生率,血清肌酐水平,和估计的肾小球滤过率(eGFR)。随机效应模型用于汇集标准平均差(SMD)和比值比(OR),CI为95%。在P小于0.05时认为有统计学意义。
    纳入三个RCT,涉及563例患者。山莨菪碱与CIN发生率降低相关[OR:0.44;95%CI:0.28,0.69;P=0.0003],在48[SMD:-6.78;95%CI:-10.54,-3.02;P=0.0004]和72h[SMD:-6.74;95%CI:-13.33,-0.15;P=0.03]时,血清肌酐水平降低,24时eGFR较高[SMD:5.77;95%CI:0.39,11.14;P=0.03],和48h[SMD:4.70;95%CI:2.03,7.38;P=0.0006]。两组24h时的血清肌酐水平和72h时的eGFR值具有可比性。
    山莨菪碱在改善AMI患者PCI后CIN的发展方面具有临床疗效。大,多中心随机对照试验是必要的,以评估这些结果的稳健性.
    UNASSIGNED: Contrast-induced nephropathy (CIN) is a common post-procedural complication of percutaneous coronary intervention for acute myocardial infarction (AMI). Anisodamine hydrobromide is an alkaloid that has demonstrated efficacy in improving microcirculation. This meta-analysis aims to evaluate the reno-protective effects of Anisodamine in patients undergoing percutaneous coronary intervention (PCI) for AMI.
    UNASSIGNED: PubMed, Embase, Cochrane Library, Scopus, and clinicaltrials.gov were searched from inception to January 2024 for randomized controlled trials (RCTs) comparing the efficacy of Anisodamine in preventing the development of CIN. Outcomes of interest included the incidence of CIN, serum creatinine levels, and estimated glomerular filtration rate (eGFR). A random-effects model was used for pooling standard mean differences (SMDs) and odds ratios (ORs) with a 95% CI. Statistical significance was considered at a P less than 0.05.
    UNASSIGNED: Three RCTs involving 563 patients were included. Anisodamine was associated with a reduction in the incidence of CIN [OR: 0.44; 95% CI: 0.28, 0.69; P=0.0003], a reduction in serum creatinine levels at 48 [SMD: -6.78; 95% CI: -10.54,-3.02; P=0.0004] and 72 h [SMD: -6.74; 95% CI: -13.33,-0.15; P=0.03], and a higher eGFR at 24 [SMD: 5.77; 95% CI: 0.39, 11.14; P=0.03], and 48 h [SMD: 4.70; 95% CI: 2.03,7.38; P=0.0006]. The levels of serum creatinine at 24 h and eGFR value at 72 h were comparable between both groups.
    UNASSIGNED: Anisodamine has demonstrated clinical efficacy in ameliorating the development of CIN post-PCI in AMI patients. Large, multi-centric RCTs are warranted to evaluate the robustness of these findings.

    脓毒症患者患膈肌萎缩和死亡率的趋势越来越大。因此,减少膈肌萎缩可能有利于脓毒症患者的预后。研究表明,山莨菪碱(Anis)在发生打击时可以发挥抗氧化作用。然而,山莨菪碱在脓毒症患者膈肌萎缩中的作用尚未见报道.因此,本研究探讨山莨菪碱对脓毒症膈肌萎缩的抗氧化作用及其机制。我们使用盲肠结扎抽吸(CLP)建立小鼠败血症模式,并用脂多糖(LPS)刺激C2C12肌管模型。用山莨菪碱治疗后,我们测量了老鼠的体重,隔膜重量,纤维横截面积和C2C12肌管的直径。使用氧化应激试剂盒检测隔膜中的丙二醛(MDA)水平。通过RT-qPCR和Westernblot检测膈肌和C2C12肌管中MuRF1、Atrogin1和JAK2/STAT3信号通路组分的表达。通过流式细胞术测量C2C12肌管中ROS的平均荧光强度。同时,我们还通过Westernblot在体内和体外测量了Drp1和细胞色素C(Cyt-C)的水平。我们的研究表明,山莨菪碱通过抑制E3泛素连接酶的表达,减轻了diaphragm肌质量的减少和diaphragm肌纤维横截面积的损失,并减轻了C2C12肌管的萎缩。此外,我们观察到山莨菪碱抑制JAK2/STAT3信号通路并保护线粒体功能。总之,山莨菪碱缓解脓毒症诱导的膈肌萎缩,机制可能与抑制JAK2/STAT3信号通路有关。
    There is an increasing tendency for sepsis patients to suffer from diaphragm atrophy as well as mortality. Therefore, reducing diaphragm atrophy could benefit sepsis patients\' prognoses. Studies have shown that Anisodamine (Anis) can exert antioxidant effects when blows occur. However, the role of Anisodamine in diaphragm atrophy in sepsis patients has not been reported. Therefore, this study investigated the antioxidant effect of Anisodamine in sepsis-induced diaphragm atrophy and its mechanism. We used cecal ligation aspiration (CLP) to establish a mouse septic mode and stimulated the C2C12 myotube model with lipopolysaccharide (LPS). After treatment with Anisodamine, we measured the mice\'s bodyweight, diaphragm weight, fiber cross-sectional area and the diameter of C2C12 myotubes. The malondialdehyde (MDA) levels in the diaphragm were detected using the oxidative stress kit. The expression of MuRF1, Atrogin1 and JAK2/STAT3 signaling pathway components in the diaphragm and C2C12 myotubes was measured by RT-qPCR and Western blot. The mean fluorescence intensity of ROS in C2C12 myotubes was measured by flow cytometry. Meanwhile, we also measured the levels of Drp1 and Cytochrome C (Cyt-C) in vivo and in vitro by Western blot. Our study revealed that Anisodamine alleviated the reduction in diaphragmatic mass and the loss of diaphragmatic fiber cross-sectional area and attenuated the atrophy of the C2C12 myotubes by inhibiting the expression of E3 ubiquitin ligases. In addition, we observed that Anisodamine inhibited the JAK2/STAT3 signaling pathway and protects mitochondrial function. In conclusion, Anisodamine alleviates sepsis-induced diaphragm atrophy, and the mechanism may be related to inhibiting the JAK2/STAT3 signaling pathway.

    背景:放射性肺损伤(RILI)是胸部肿瘤放疗的常见副作用,包括早期放射性肺损伤(RP)和晚期放射性肺纤维化(RIPF)。目前,迫切需要阐明RILI的发病机制,寻找安全有效的RILI治疗方法。辐照引起组织和细胞的DNA损伤和氧化应激,诱导细胞衰老,促进了RILI的发生和发展。近年来,山莨菪碱(654-2)在急性肺损伤中显示出潜在的治疗价值,急性肾损伤,衣原体肺炎,和COVID-19。然而,目前尚无关于654-2介导的细胞衰老的机制及其对RILI的预防和治疗作用的研究。
    目的:本研究旨在探讨654-2对X射线诱导的RILI的保护作用及其机制。
    方法:体内实验涉及18GyX射线照射的小鼠RILI模型。将小鼠分为对照组,模型,药物(对照+654-2),和治疗组(模型+654-2)。药物和治疗组小鼠每隔一天腹腔注射5mg/kg654-2,直至第6周处死。体外实验使用16Gy照射的MLE-12细胞,并分为对照组,模型,和模型+654-2(2μM和10μM)组。进行各种测定以评估肺组织形态学,纤维化,凋亡,细胞因子表达,细胞衰老,蛋白质表达,和抗氧化能力。
    结果:654-2减轻了肺部病理损害,炎症,DNA损伤,细胞衰老,和RILI小鼠和MLE-12细胞的凋亡。恢复上皮细胞增殖能力,增强抗氧化能力。此外,654-2激活了Nrf2/ARE途径,Nrf2磷酸化增加,并上调抗氧化基因的表达。抑制Nrf2逆转了654-2对ROS产生的影响,抗氧化能力,和细胞衰老。
    结论:654-2可以激活Nrf2/ARE通路,增强细胞抗氧化能力,抑制细胞衰老,从而发挥对RILI的保护作用。
    BACKGROUND: Radiation-induced lung injury (RILI) is a common side effect of thoracic tumor radiotherapy, including early-stage radiation-induced lung injury (RP) and late-stage radiation-induced pulmonary fibrosis (RIPF). Currently, it is urgently needed to clarify the pathogenesis of RILI and find safe and effective RILI treatment methods. Irradiation causes DNA damage and oxidative stress in tissues and cells, induces cellular senescence, and promotes the occurrence and development of RILI. In recent years, Anisodamine (654-2) has shown potential therapeutic value in acute lung injury, acute kidney injury, chlamydial pneumonia, and COVID-19. However, there is currently no research on the mechanism of 654-2-mediated cellular senescence and its preventive and therapeutic effects on RILI.
    OBJECTIVE: This study aimed to investigate the protective effect and mechanism of 654-2 on X-ray-induced RILI.
    METHODS: In vivo experiments involved a mouse RILI model with 18 Gy X-ray irradiation. Mice were divided into control, model, medication (control + 654-2), and treatment (model + 654-2) groups. And mice in medication and treatment groups were intraperitoneal injection of 5 mg/kg 654-2 every other day until being sacrificed at week 6. In vitro experiments used MLE-12 cells irradiated with 16 Gy and divided into control, model, and model + 654-2(2 μM and 10 μM) groups. Various assays were performed to evaluate lung tissue morphology, fibrosis, apoptosis, cytokine expression, cellular senescence, protein expression, and antioxidant capacity.
    RESULTS: 654-2 mitigated pulmonary pathological damage, inflammation, DNA damage, cellular senescence, and apoptosis in RILI mice and MLE-12 cells. It restored epithelial cell proliferation ability and enhanced antioxidant capacity. Additionally, 654-2 activated the Nrf2/ARE pathway, increased Nrf2 phosphorylation, and upregulated antioxidant gene expression. Inhibition of Nrf2 reversed the effects of 654-2 on ROS production, antioxidant capacity, and cell senescence.
    CONCLUSIONS: 654-2 can activate the Nrf2/ARE pathway, enhance cellular antioxidant capacity, and inhibit cellular senescence, thereby exerting a protective effect against RILI.

    方法:将90例腹腔镜袖状胃切除术患者随机分为山莨菪碱组和对照组,比例为2:1。全身麻醉诱导后,向足三里(ST36)双侧注射山莨菪碱或生理盐水。在术后前3天和术后3个月评估PONV的发生率和严重程度。麻醉早期恢复的质量,胃肠功能,睡眠质量,焦虑,抑郁症,并对并发症进行了评估。
    结果:两组的基线和围手术期特征具有可比性。在山莨菪碱组中,25例患者(42.4%)在术后24h内发生呕吐,而对照组为21例(72.4%)(相对风险0.59;95%置信区间0.40-0.85)。山莨菪碱组首次解救止吐时间为6.5h,对照组为1.7h(P=0.011)。山莨菪碱组的前24小时内需要较少的抢救止吐(P=0.024)。术后恶心或其他恢复特征均无差异。
    结论:ST36穴位注射山莨菪碱可显著减少女性肥胖患者腹腔镜袖状胃切除术后呕吐,且不影响恶心。
    The use of multimodal pharmacological prophylactic regimes has decreased postoperative nausea and vomiting (PONV) in general but it still occurs in over 60% of female patients after bariatric surgery. This study aimed to evaluate the efficacy of ST36 acupoint injection with anisodamine in prevention of PONV among female patients after bariatric surgery.
    Ninety patients undergoing laparoscopic sleeve gastrectomy were randomly allocated to anisodamine or control group at the ratio of 2:1. Anisodamine or normal saline was injected into Zusanli (ST36) bilaterally after induction of general anesthesia. The incidence and severity of PONV were assessed during the first 3 postoperative days and at 3 months. The quality of early recovery of anesthesia, gastrointestinal function, sleep quality, anxiety, depression, and complications were also evaluated.
    Baseline and perioperative characteristics were comparable between two groups. In the anisodamine group, 25 patients (42.4%) experienced vomiting within postoperative 24 h compared with 21 (72.4%) in the control group (relative risk 0.59; 95% confidence interval 0.40-0.85). Time to first rescue antiemetic was 6.5 h in anisodamine group, and 1.7 h in the control group (P = 0.011). Less rescue antiemetic was required during the first 24 h in the anisodamine group (P = 0.024). There were no differences in either postoperative nausea or other recovery characteristics.
    The addition of ST36 acupoint injection with anisodamine significantly reduced postoperative vomiting without affecting nausea in female patients with obesity undergoing laparoscopic sleeve gastrectomy.

    Anisodamine is an anticholinergic drug extracted and isolated from the Anisodus tanguticus (Maxim.) Pascher of the Solanaceae family which is also a muscarinic receptor antagonist. Owing to the lack of natural sources of anisodamine, synthetic products are now used. Using ornithine and arginine as precursor compounds, putrescine is catalyzed by different enzymes and then undergoes a series of reactions to produce anisodamine. It has been used clinically to protect cardiac function and treat septic shock, acute pancreatitis, calculous renal colic, bronchial asthma, blood circulation disturbances, jaundice, analgesia, vertigo, acute poisoning, and other conditions.This review describes the relevant pharmacokinetic parameters. Anisodamine is poorly absorbed in the gastrointestinal tract, and it is not as effective as intravenous administration. For clinical medication, intravenous infusion should be used rather than rapid intravenous injection. With the advancement of research in recent years, the application scope of anisodamine has expanded, with significant developments and application values surging.This review systematically describes the sources, pharmacokinetics, pharmacological effects and clinical application of anisodamine, in order to provide a basis for clinical use.

    黑斑青蛙营养丰富,肉质可口,市场消费量逐年增加。然而,疾病的爆发给养殖业造成了巨大损失。由Elizabethkingiamiricola(E.miricola)具有高度传染性和致命性,没有有效的治疗方法。疫苗接种是预防传染病最有前途的策略。浸入式疫苗接种因其预防传染病的操作简单而吸引了许多研究人员。此外,与佐剂一起使用时,浸泡疫苗可能更有效。在这项研究中,我们用0.3%的甲醛制备了灭活的E.miricola,黑色斑点青蛙通过浸泡在灭活的E.miricola疫苗中接种疫苗,山莨菪碱+疫苗混合物,β-葡聚糖+疫苗混合物,壳聚糖+疫苗混合物60分钟。PBS用作对照。在受到E.miricola的挑战后,山莨菪碱+疫苗组(57%)和壳聚糖+疫苗组(63%)的存活率明显高于对照组(17%)。通过分析病理切片,我们发现壳聚糖+疫苗和山莨菪碱+疫苗组保护大脑,眼睛,与对照组相比,黑斑青蛙的肝脏和肾脏组织,与生存率趋势一致。此外,壳聚糖+疫苗和山莨菪碱+疫苗组对LZM有较好的效果,血清中TSOD和C3高于对照组。同时,免疫黑斑蛙外周血中白细胞/血细胞百分比的数量增加。山莨菪碱+疫苗组(5.3%)和壳聚糖+疫苗组(5.38%)明显高于空白对照组(2.24%),这表明两组诱导了更显著的免疫反应,对细菌入侵的抵抗力更强。肝脏中的组织细菌负荷,大脑,山莨菪碱+疫苗组和壳聚糖+疫苗组肾脏和眼睛明显低于对照组。本研究探索并证明了壳聚糖和山莨菪碱作为浸泡免疫佐剂的良好功效,为提高浸泡免疫效率提供了参考。
    Black spotted frogs have rich nutrition and delicious meat, and its market consumption has increased year by year. However, outbreaks of the diseases have caused huge losses to the breeding industry. The crooked head disease caused by Elizabethkingia miricola (E. miricola) is highly contagious and lethal, and there is no effective treatment method. Vaccination is the most promising strategy to prevent infectious diseases. Immersion vaccination has attracted many researchers because of its simplicity of operation in preventing infectious diseases. In addition, immersion vaccines can be more effective when used with adjuvants. In this study, we prepared inactivated E. miricola with 0.3% formaldehyde, and the black spotted frogs were vaccinated by soaking in inactivated E. miricola vaccine, anisodamine + vaccine mixture, β-glucan + vaccine mixture, chitosan + vaccine mixture for 60 min. PBS was used as a control. After being challenged by E. miricola, the survival rate of anisodamine + vaccine (57%) and chitosan + vaccine group (63%) was significantly higher than that of the control group (17%). By analyzing pathological sections, we found that the chitosan + vaccine and anisodamine + vaccine groups protected the brain, eye, liver and kidney tissues of the black spotted frogs compared to the control group, which was consistent with the trend of survival rate. In addition, chitosan + vaccine and anisodamine + vaccine groups had better effects on LZM, TSOD and C3 in serum than control group. Meanwhile, the numbers of the percentage of leukocytes/haemocytes in the peripheral blood of immunized black spotted frogs increased. The anisodamine + vaccine group (5.3%) and chitosan + vaccine (5.38%) group were significantly higher than the blank control group (2.24%), which indicate that the two groups induced a more significant immune response and were more resistant to bacterial invasion. The tissue bacterial loads in liver, brain, kidney and eye were significantly lower in the anisodamine + vaccine and chitosan + vaccine groups than that of the control group. This study explored and demonstrated the good efficiency of chitosan and anisodamine as adjuvants for immunization by immersion and provided a reference for improving the efficiency of immunization by immersion.

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) provoked a pandemic of acute respiratory disease, namely coronavirus disease 2019 (COVID-19). Currently, effective drugs for this disease are urgently warranted. Anisodamine is a traditional Chinese medicine that is predicted as a potential therapeutic drug for the treatment of COVID-19. Therefore, this study aimed to investigate its antiviral activity and crucial targets in SARS-CoV-2 infection. SARS-CoV-2 and anisodamine were co-cultured in Vero E6 cells, and the antiviral activity of anisodamine was assessed by immunofluorescence assay. The antiviral activity of anisodamine was further measured by pseudovirus entry assay in HEK293/hACE2 cells. Finally, the predictions of crucial targets of anisodamine on SARS-CoV-2 were analyzed by molecular docking studies. We discovered that anisodamine suppressed SARS-CoV-2 infection in Vero E6 cells, and reduced the SARS-CoV-2 pseudovirus entry to HEK293/hACE2 cells. Furthermore, molecular docking studies indicated that anisodamine may target SARS-CoV-2 main protease (Mpro) with the docking score of -6.63 kcal/mol and formed three H-bonds with Gly143, Cys145, and Cys44 amino acid residues at the predicted active site of Mpro. This study suggests that anisodamine is a potent antiviral agent for treating COVID-19.
