Objective

The occurrence and development of atrial fibrillation (AF) are influenced by the autonomic nervous system and inflammation. Acupuncture is an effective treatment for AF. This study explored the protective effects of acupuncture in a rat model of paroxysmal AF and investigated its mechanisms.

Methods

Male Sprague-Dawley rats (n = 130) were randomly divided into blank control (Con), sham operation (Sham), AF, and acupuncture treatment (Acu) groups. A paroxysmal AF model was established by rapid atrial pacing through the jugular vein. Rats in the Acu group were immobilized to receive acupuncture treatment at Neiguan acupoint (PC6) for 20 min daily for seven days. The other groups were immobilized for the same duration over the treatment period but did not receive acupuncture. The AF induction rate, AF duration, cardiac electrophysiological parameters, and heart rate variability were evaluated by monitoring surface electrocardiogram and vagus nerve discharge signals. After the intervention, the rats were euthanized, and atrial morphology was assessed using haematoxylin and eosin staining. The expression of macrophage F4/80 antigen (F4/80) and cluster of differentiation (CD) 86 in atrial myocardial tissue was detected using immunohistochemistry, immunofluorescence and flow cytometry. The expression levels or contents of interleukin (IL)-1β, IL-6, tumor necrosis factor-α (TNF-α), α7 nicotinic acetylcholine receptor (α7nAChR), phosphorylated Janus kinase 2 (p-JAK2), and phosphorylated signal transducer and activator of transcription 3 (p-STAT3) in atrial myocardial tissue were detected using Western blotting, reverse transcription-quantitative polymerase chain reaction, or enzyme-linked immunosorbent assay. The role of α7nAChR in acupuncture treatment was verified by intraperitoneal injection of the α7nAChR antagonist methyllycaconitine (MLA).

Results

Compared with the AF group, acupuncture significantly reduced AF duration and induction rate, improved cardiac electrophysiology by enhancing vagus nerve activity and regulating autonomic balance. It also decreased the pro-inflammatory M1 macrophage proportion, alleviating myocardial injury and infiltration. MLA weakened acupuncture’s electrophysiological improvement and anti-inflammatory effect. Results suggest that acupuncture triggers the α7nAChR-JAK2/STAT3 pathway and exerts cardioprotection via neuroimmune regulation.

Conclusion

Acupuncture significantly reduced the AF induction rate, shortened AF duration, improved cardiac electrophysiological parameters, enhanced vagus nerve activity, and decreased the expression of pro-inflammatory M1 macrophages and inflammatory factors in rats with paroxysmal AF. Its positive effects are related to the activation of the α7nAChR-mediated JAK2/STAT3 signalling pathway, indicating that the interaction between cardiac vagus nerve and macrophages
目的:心房颤动(AF)的发生和发展受自主神经系统和炎症的影响。针刺是治疗房颤的有效方法。本研究探讨针刺对阵发性房颤大鼠模型的保护作用,并探讨其机制。方法:雄性Sprague-Dawley大鼠130只,随机分为空白对照组(Con)、假手术组(sham)、AF组(AF)和针刺治疗组(Acu)。采用颈静脉快速心房起搏法建立阵发性房颤模型。Acu组大鼠固定于内关穴(PC6),每日20 min,连续7 d。其他组在治疗期间固定相同时间,但不接受针灸。通过监测体表心电图和迷走神经放电信号,评估AF诱导率、AF持续时间、心电生理参数和心率变异性。干预后对大鼠实施安乐死,采用苏木精和伊红染色评价心房形态。采用免疫组织化学、免疫荧光和流式细胞术检测心房心肌组织巨噬细胞F4/80抗原(F4/80)和分化簇(cd86)的表达。采用Western blotting、逆转录-定量聚合酶链反应或酶联免疫吸附法检测心房心肌组织中白细胞介素(IL)-1β、IL-6、肿瘤坏死因子-α (TNF-α)、α7烟碱胆碱受体(α7nAChR)、磷酸化Janus激酶2 (p-JAK2)、磷酸化信号转导和转录激活因子3 (p-STAT3)的表达水平或含量。通过腹腔注射α7nAChR拮抗剂甲基莱卡乌碱(MLA)验证α7nAChR在针刺治疗中的作用。结果:与房颤组比较,针刺可显著缩短房颤持续时间和诱导率,通过增强迷走神经活动和调节自主神经平衡改善心电生理。降低促炎M1巨噬细胞比例,减轻心肌损伤和浸润。MLA减弱了针刺的电生理改善和抗炎作用。提示针刺可触发α7nAChR-JAK2/STAT3通路,通过神经免疫调节发挥心脏保护作用。结论:针刺可显著降低阵发性AF大鼠AF诱导率,缩短AF持续时间,改善心脏电生理参数,增强迷走神经活性,降低促炎M1巨噬细胞及炎症因子的表达,其积极作用与α 7nachr介导的JAK2/STAT3信号通路的激活有关。表明心脏迷走神经与巨噬细胞之间的相互作用可能是针刺预防和治疗房颤的潜在靶点。本文署名:李振华,杨文明,黄强,石桂霞,刘长忠,张永强。针刺通过α7nAChR-JAK2/STAT3通路激活迷走神经-巨噬细胞轴,改善心房颤动大鼠心脏电生理和炎症反应。集成医学[J];打印前Epub。

Objective

Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA.

Methods

This cross-sectional case-control study enrolled cases aged 45–75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance.

Results

The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m2) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m2). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA.

Conclusion

Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.

Cynanchum atratum Bunge (C. atratum) and Cynanchum versicolor Bunge (C. versicolor) are two related species that have been used as “Baiwei” (Cynanchi Atrati Radix Et Rhizoma) in traditional medicine in China and other Asian countries for a long time. However, to date, no comprehensive review of C. atratum and C. versicolor has been published. This review provides a comprehensive summary on the botany, phytochemistry, traditional uses and pharmacology of Baiwei; The authors focus especially on the revision of errors in previous articles and reviews, updating information and providing a comparison of C. atratum and C. versicolor. Furthermore, current research reveals significant disparities in the chemical composition and pharmacological effects between C. atratum and C. versicolor. Up to November 2023, 178 compounds have been isolated from C. atratum and C. versicolor, including C21 steroids, acetophenones, alkaloids and volatile oils. These compounds and extracts have been proven to exhibit significant pharmacological activities, including anti-inflammatory, anti-tumor, anti-virus, anti-fungal, memory-enhancing and anti-pyretic action, immune modulatory effects, reducing blood lipid, inhibition of melanin production, and anti-parasitic effects. Therefore, this review presents new insights into these two herbs used as “Baiwei” and further study is warranted to enhance their clinical application.

Background

Acupuncture has shown potential therapeutic benefits for individuals with simple obesity. However, some researchers argue that some of the effectiveness of acupuncture may be due to the placebo response.

Objective

To understand the placebo response of acupuncture treatment in simple obesity, a systematic review and meta-analysis was designed based on the comparison between sham acupuncture before and after treatment.

Search strategy

Eight databases (PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang Database, China Biology Medicine Database, and Chinese Scientific Journals Database) were searched from inception to August 1, 2023. The MeSH search terms comprised obesity and acupuncture.

Inclusion criteria

Randomized controlled trials (RCTs) using sham or placebo acupuncture as a control in treating obesity were enrolled.

Data extraction and analysis

Two researchers independently extracted data, and the results were cross-checked after completion. Each RCT’s detailed sham/placebo acupuncture treatment protocol was assessed according to the SHam Acupuncture REporting guidelines. The revised Cochrane risk-of-bias tool for randomized trials and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system were used to determine the risk of bias and quality of evidence, respectively. Body mass index (BMI) was defined as the primary outcome. Anthropometric parameters and laboratory test parameters related to obesity were defined as secondary outcomes. We used standardized mean difference (SMD) with 95% confidence interval (CI) to calculate treatment effects of outcomes.

Results

Fifteen RCTs with a total of 1250 patients were included. The BMI significantly decreased after treatment in the sham acupuncture group compared to baseline (SMD 0.37, 95% CI 0.09–0.66; I2 = 81%, random model; P < 0.01). Treatment duration (P = 0.02) and other interventions significantly impacted the placebo response rate (P = 0.00).

Conclusion

The placebo response of sham acupuncture was strong in the RCTs for simple obesity, and the effect sizes differed between various outcomes. The treatment duration and other interventions emerged as potential influencing factors for the placebo response of sham acupuncture.

Metabolic syndrome (MetS) is a cluster of risk factors that significantly increase the chances of developing heart disease, type 2 diabetes mellitus, stroke, and other cardiovascular complications. Since current anti-MetS medications like statins, angiotensin-converting enzyme inhibitors, β-blockers, insulin sensitizers and diuretics have been reported to cause unwanted side effects, researchers are exploring promising alternatives. One such alternative relies on the potential of spices and condiments, which have a long history of use in traditional medicine. Among them, Cinnamomum zeylanicum Blume stands out as a popular spice worldwide for its unique taste, aroma, and delicate sweetness compared to other cinnamon varieties. This narrative review aims to summarize the in vivo and clinical evidence concerning the efficacy of C. zeylanicum against MetS indices. Relevant articles from PubMed, Scopus and Google scholar databases were reviewed. In vivo results suggested that C. zeylanicum preparations (extracts, essential oil, crude powder, bioactive compounds, and biosynthesized nanoparticles) were remarkably efficient in ameliorating MetS indices, while the clinical data were less and with several methodological limitations. Further robust clinical studies are warranted to definitively establish C. zeylanicum as a promising functional food for mitigating MetS, potentially leading to its dietary integration as a natural approach to improve metabolic health.

代谢综合征(MetS)是一组显著增加患心脏病、2型糖尿病、中风和其他心血管并发症几率的危险因素。由于目前的抗代谢代谢药物,如他汀类药物、血管紧张素转换酶抑制剂、β受体阻滞剂、胰岛素增敏剂和利尿剂,据报道会引起不必要的副作用,研究人员正在探索有希望的替代品。其中一种替代方案依赖于香料和调味品的潜力,它们在传统医学中有着悠久的使用历史。其中,肉桂(Cinnamomum zeylanicum Blume)以其独特的口感、香气和细腻的甜味,与其他肉桂品种相比,成为全球流行的香料。本文综述了zeylanicum对MetS指标的体内和临床疗效。检索PubMed、Scopus和谷歌学者数据库的相关文章。体内实验结果表明,莪术制剂(提取物、精油、粗粉、生物活性化合物和生物合成纳米颗粒)对改善MetS指数有显著的效果,但临床数据较少,并且存在一些方法学上的局限性。进一步强有力的临床研究有必要明确地确定C. zeylanicum作为一种有前景的功能食品,以减轻MetS,可能导致其饮食整合作为一种自然的方法来改善代谢健康。这篇文章请注明出处:Adarthaiya S, Arivarasan VK。肉桂治疗代谢综合征的潜力:来自体内和人体研究的见解。集成医学[J];打印前Epub。

Background

Modern acupuncture anesthesia is a combination of Chinese and Western medicine that integrates the theories of acupuncture with anesthesia. However, some clinical studies of acupuncture anesthesia lack specific descriptions of randomization, allocation concealment, and blinding processes, with subsequent systematic reviews indicating a risk of bias.

Objective

Clinical trial registration is essential for the enhancement of the quality of clinical trials. This study aims to summarize the status of clinical trial registrations for acupuncture anesthesia listed on the World Health Organization International Clinical Trials Registry Platform (ICTRP).

Search strategy

We searched the ICTRP for clinical trials related to acupuncture anesthesia registered between January 1, 2001 and May 31, 2023. Additionally, related publications were retrieved from PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Data. Registrations and publications were analyzed for consistency in trial design characteristics.

Inclusion criteria

Clinical trials that utilized one of several acupuncture-related therapies in combination with pharmacological anesthesia during the perioperative period were eligible for this review.

Data extraction and analysis

Data extracted from articles included type of surgical procedure, perioperative symptoms, study methodology, type of intervention, trial recruitment information, and publication information related to clinical enrollment.

Results

A total of 166 trials related to acupuncture anesthesia from 21 countries were included in the analysis. The commonly reported symptoms in the included studies were postoperative nausea and vomiting (19.9%) and postoperative pain (13.3%). The concordance between the publications and the trial protocols in the clinical registry records was poor, with only 31.7% of the studies being fully compatible. Inconsistency rates were high for sample size (39.0%, 16/41), blinding (36.6%, 15/41), and secondary outcome indicators (24.4%, 10/41).

Conclusion

The volume of acupuncture anesthesia clinical trials registered in international trial registries over the last 20 years is low, with insufficient disclosure of results. Postoperative nausea and vomiting as well as postoperative pain, are the most investigated for acupuncture intervention.

Objective

Xuebijing injection has been recommended as a therapeutic approach for individuals with severe and critical COVID-19. This study aims to explore the correlation of neutrophil to lymphocyte platelet ratio (NLPR) with the severity and prognosis of COVID-19, and the effect of XBJ on the prognosis of patients with COVID-19 in different inflammatory states.

Methods

This was a retrospective study conducted at Wuhan Union Hospital in China. COVID-19 patients admitted between November 1, 2022 and February 1, 2023 were included. In predicting prognosis for individuals with COVID-19, new inflammatory indicators were used, and their prognostic value was assessed by using Cox regression models and receiver operating characteristic curves. Furthermore, a calculation was made to determine the cutoff value for NLPR. Relative risk and Cox regression models were used to examine the effects of Xuebijing injection on prognosis in patient cohorts that had been stratified by the NLPR cutoff.

Results

This research included 455 participants with COVID-19, with a mean age of 72 years. Several inflammatory indicators were found to be strongly correlated with prognosis, and NLPR shows the greatest predictive power. Patients with NLPR > 3.29 exhibited a mortality rate of 17.3%, which was 6.2 times higher than in patients with NLPR ≤ 3.29. Importantly, providing Xuebijing injection to patients with NLPR > 3.29 was associated with a lower risk of 60-day all-cause mortality. However, there was no discernible improvement in survival among patients with NLPR ≤ 3.29 who received Xuebijing injection.

Conclusion

NLPR is the most reliable inflammatory marker for predicting prognosis among individuals with COVID-19, and can accurately identify individuals who may benefit from Xuebijing injection.

Objective

To investigate whether the presence or absence of improvement in chronic severe functional constipation (CSFC) at the early stage of treatment with electroacupuncture predicts subsequent response or non-response, and to determine the optimal treatment duration for assessing subsequent responses to electroacupuncture.

Methods

This is a post hoc analysis using data pooled from two large-scale randomized controlled trials. Patients with CSFC were recruited, and those in the electroacupuncture groups were included in the present study. Early improvement was defined as a weekly increase of ≥1 complete spontaneous bowel movement (CSBM) compared to baseline. Three treatment response criteria were evaluated: ≥ 3 CSBMs per week, overall CSBM response, and sustained CSBM response. Predictive statistics, including sensitivity, specificity, positive predictive value, and negative predictive value, were calculated at weeks 1–4. Receiver operating characteristic curves and accuracy rates were used to determine the optimal timepoint for differentiation between responders and non-responders.

Results

Cases from a total of 813 participants who received electroacupuncture were analyzed. The proportion of improvers was 40.34% by week 1, increasing to 52.52% by week 4. After 8 weeks of treatment, the response rates were 30.14%, 25.83% and 25.58% according to the three aforementioned criteria, respectively. Early improvement was a strong predictor of treatment response, with week 3 demonstrating the highest predictive accuracy.

Conclusion

Early improvement with electroacupuncture, especially at week 3, can predict subsequent outcomes. Our findings suggest that acupuncturists may identify non-responders who might require adjustments to therapeutic strategies early in treatment.

Objective

Gastric cancer (GC) is one of the most common malignancies seen in clinic and requires novel treatment options. Morin is a natural flavonoid extracted from the flower stalk of a highly valuable medicinal plant Prunella vulgaris L., which exhibits an anti-cancer effect in multiple types of tumors. However, the therapeutic effect and underlying mechanism of morin in treating GC remains elusive. The study aims to explore the therapeutic effect and underlying molecular mechanisms of morin in GC.

Methods

For in vitro experiments, the proliferation inhibition of morin was measured by cell counting kit-8 assay and colony formation assay in human GC cell line MKN45, human gastric adenocarcinoma cell line AGS, and human gastric epithelial cell line GES-1; for apoptosis analysis, microscopic photography, Western blotting, ubiquitination analysis, quantitative polymerase chain reaction analysis, flow cytometry, and RNA interference technology were employed. For in vivo studies, immunohistochemistry, biomedical analysis, and Western blotting were used to assess the efficacy and safety of morin in a xenograft mouse model of GC.

Results

Morin significantly inhibited the proliferation of GC cells MKN45 and AGS in a dose- and time-dependent manner, but did not inhibit human gastric epithelial cells GES-1. Only the caspase inhibitor Z-VAD-FMK was able to significantly reverse the inhibition of proliferation by morin in both GC cells, suggesting that apoptosis was the main type of cell death during the treatment. Morin induced intrinsic apoptosis in a dose-dependent manner in GC cells, which mainly relied on B cell leukemia/lymphoma 2 (BCL-2) associated agonist of cell death (BAD) but not phorbol-12-myristate-13-acetate-induced protein 1. The upregulation of BAD by morin was due to blocking the ubiquitination degradation of BAD, rather than the transcription regulation and the phosphorylation of BAD. Furthermore, the combination of morin and BCL-2 inhibitor navitoclax (also known as ABT-737) produced a synergistic inhibitory effect in GC cells through amplifying apoptotic signals. In addition, morin treatment significantly suppressed the growth of GC in vivo by upregulating BAD and the subsequent activation of its downstream apoptosis pathway.

Conclusion

Morin suppressed GC by inducing apoptosis, which was mainly due to blocking the ubiquitination-based degradation of the pro-apoptotic protein BAD. The combination of morin and the BCL-2 inhibitor ABT-737 synergistically amplified apoptotic signals in GC cells, which may overcome the drug resistance of the BCL-2 inhibitor. These findings indicated that morin was a potent and promising agent for GC treatment.

目的:胃癌(GC)是临床上最常见的恶性肿瘤之一,需要新的治疗方案。桑里素是从药用植物Prunella vulgaris L.的花茎中提取的一种天然类黄酮,对多种肿瘤均有抗癌作用。然而,桑辣素治疗胃癌的疗效和机制尚不清楚。本研究旨在探讨桑苷对胃癌的治疗作用及其分子机制。方法:采用细胞计数试剂盒-8法和集落形成法对人胃癌细胞系MKN45、人胃腺癌细胞系AGS和人胃上皮细胞系GES-1进行体外增殖抑制实验;细胞凋亡分析采用显微摄影、Western blotting、泛素化分析、定量聚合酶链反应分析、流式细胞术和RNA干扰技术。在体内研究中,采用免疫组织化学、生物医学分析和Western blotting来评估桑里酯对异种移植小鼠GC模型的有效性和安全性。结果:桑辣素显著抑制胃癌细胞MKN45和AGS的增殖,且呈剂量和时间依赖性,但对人胃上皮细胞GES-1无抑制作用。在两种GC细胞中,只有caspase抑制剂Z-VAD-FMK能够显著逆转桑肽对细胞增殖的抑制作用,提示凋亡是治疗过程中细胞死亡的主要类型。桑辣素以剂量依赖性方式诱导GC细胞内在凋亡,主要依赖于B细胞白血病/淋巴瘤2 (BCL-2)相关的细胞死亡激动剂(BAD),而不依赖于phorpol -12-肉豆酸盐-13-乙酸盐诱导的蛋白1。桑辣素对BAD的上调是由于阻断BAD的泛素化降解,而不是由于对BAD的转录调控和磷酸化。此外,morin与BCL-2抑制剂navitoclax(也称为ABT-737)联合使用,通过放大凋亡信号,对GC细胞产生协同抑制作用。此外,桑皮素处理通过上调BAD并激活其下游凋亡通路,显著抑制体内GC的生长。结论:桑辣素对GC的抑制作用主要是通过抑制促凋亡蛋白BAD的泛素化降解。桑苷与BCL-2抑制剂ABT-737联用可协同放大胃癌细胞的凋亡信号,可能克服BCL-2抑制剂的耐药。这些结果表明,桑皮素是一种有效的、有前途的气相色谱治疗剂。本文署名:王毅,孙学勇,马方强,任敏,赵荣荣,秦敏,朱晓华,徐毅,曹德宁,陈奕云,董国涛,潘云峰,赵爱岗。Morin抑制胃癌细胞中BCL-2相关细胞死亡激动剂的泛素化降解并与BCL-2抑制剂协同作用。集成医学[J];打印前Epub。
