In recent years, the number of functional magnetic resonance imaging (fMRI) research in acupuncture grows increasingly. However, due to the differences in acupoint selection, acupuncture technique and sample size, the problems get more prominent in terms of the diverse results and the lack of common rules of acupuncture among researches. By taking the fMRI research for post-stroke motor dysfunction (PSMD) treated with acupuncture as the example, this paper introduces the fMRI Meta-analysis technology for integrating the relevant research results and extracting the common rules, namely image-based Meta-analysis (IBMA) and coordinate-based Meta-analysis (CBMA). Considering the higher feasibility of CBMA, three available CBMA methods are explained specially, including activation likelihood estimation (ALE), kernel density analysis (KDA), and seed-based d mapping (SDM). Focusing on the precautions and operation procedure of CBMA, the review is conducted systematically on the type of fMRI research, task design, analytical method, and the thinking integrity of fMRI Meta-analysis, and the review findings are collated in charts. It aims to assist readers to understand the abstract and complex theories and practical information of this technology efficiently, conveniently and systematically, and hopes to provide the references for the future learning and the application.

Acupuncture in the treatment of post-stroke hiccup: A systematic Review and meta-analysis.

Aim: Central hiccups following a stroke are a frequent complication, exerting adverse effects on both the stroke condition and the patient's daily life. Existing treatments exhibit limited efficacy and pronounced side effects. Acupuncture has been explored as a supplementary intervention in clinical practice. This study aims to investigate the clinical effectiveness of acupuncture for post-stroke hiccups.Methods: To identify published clinical randomized controlled trials addressing post-stroke hiccups treatment, comprehensive searches were conducted across PubMed, the Cochrane Library, EMBASE, Web of Science, Chinese Biological Medical (CBM), Wanfang Database, and China Science and Technology Journal (VIP). In addition, we scrutinized ClinicalTrials.gov and the Chinese Clinical Trial Registry. Employing Cochrane Handbook 5.1.0 and Review Manager 5.4 software, three authors independently reviewed literature, extracted data, and evaluated study quality. Data analysis was performed using Stata 16.0 and Review Manager 5.4.Results: A total of 18 trials were encompassed in the analysis. In comparison to standard treatment, acupuncture exhibited a significant enhancement in treatment effectiveness (RR: 1.27, 95% CI: 1.21-1.33; P < 0.00001). Notably, Hiccup Symptom Score displayed a considerable decrease (WMD: -1.28, 95% CI: -1.64 to -0.93; P < 0.00001), concurrent with a noteworthy improvement in the quality of life (WMD: 8.470, 95% CI: 7.323-9.617; P < 0.00001). Additionally, the incidence of adverse reactions decreased (RR: 0.45, 95% CI: 0.16-1.25; P = 0.13), and there was a significant reduction in SAS (WMD: -7.23, 95% CI: -8.47 - -5.99; P < 0.00001).Conclusions: Our investigation suggests that acupuncture could prove effective in post-stroke hiccup treatment. Nonetheless, due to concerns about the quality and size of the included studies, conducting higher-quality randomized controlled trials to validate their efficacy is imperative.

Influence of Acupuncture and Other Clinical Factors on the Recovery of Limb Motor Function in Patients After Stroke: A Retrospective Study.

Background: Limb motor disorders after stroke are very common, and the clinical related factors of improving limb motor function are still unclear. As a part of comprehensive rehabilitation strategy, acupuncture has been widely used in rehabilitation after stroke in China. But more evidence is needed for the influence of acupuncture and some other clinical factors on post-stroke motor disorders. Patients and Methods: A retrospective study was conducted using the database of patients with post-stroke motor disorders admitted to the Neurological Rehabilitation Unit of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine. The included patients were grouped according to whether NIHSS improved or muscle strength improved. The positive logistic regression was used to analyze the influencing factors of possible NIHSS improvement. Combined with the influencing factors of NIHSS improvement and muscle strength improvement, the influencing factors of limb motor function recovery after stroke were obtained. Results: When analyzing the baseline of the included patients, it was found that patients with NIHSS improvement had earlier acupuncture intervention time (M, (IQR):13.5 (14), OR=0.716, 95% CI [0.591-0.869], p=0.001), more cumulative acupuncture treatment times (M,(IQR):29 (12), OR=0.744, 95% CI [0.608-0.910], p=0.004), and less hypertension history (OR=0.256, 95% CI [0.082-0.801], p=0.019). Smoking history only has positive significance in univariate and multivariate analysis of NIHSS, not muscle strength (OR=0.274, 95% CI [0.097-0.779], p=0.015). Conclusion: The earlier acupuncture intervention and the more cumulative acupuncture treatment times are, the more beneficial the limb function of stroke patients with motor disorders will be. The previous history of hypertension is the influencing factor of limb motor function not improving in patients with limb motor disorder after a stroke. The effect of smoking history on limb movement function of patients with limb motor disorder after stroke needs further study.

Electroacupuncture reverses endothelial cell death and promotes angiogenesis through the VEGF/Notch signaling pathway after focal cerebral ischemia-reperfusion injury.

BACKGROUND: Angiogenesis is an important mechanism of recovery from ischemic stroke. Recent studies have found that there is a close relationship between the VEGF/Notch pathway and angiogenesis. It is unknown whether EA can exert a brain protection effect and promote angiogenesis by acting on the VEGF/Notch signaling pathway after focal cerebral ischemia-reperfusion injury (CIRI). METHODS: The Middle Cerebral Artery occlusion/Reperfusion (MCAo/R) model was established, in which rats were subjected to occlusion with ischemic intervention for 30 min, followed by reperfusion for 8 h, 1 day, 3 days, and 7 days. The first EA treatment was performed 90 min after the animal model was successfully established, and then EA treatments were performed once a day for 7 days. The 2,3,5-triphenyltetrazolium chloride staining and neurological deficit examination were performed to assess the level of CIRI and neuroprotection by EA. Expression levels of VEGFA, Notch1, and Hes1 proteins were measured via western blotting, while the morphological changes of ECs and microvasculature in the cortex were determined using an ultrastructural observation method. RESULTS: EA treatment of PC6, GV26, and SP6 can significantly improve the neurological function of MCAO/R rats, reduce the volume of cerebral infarction, and modulate the ultrastructure of ECs and microvessels in pathological states. Western blotting revealed that EA increased VEGFA protein expression at 8 h and 3 days after CIRI, as well as Notch1 protein expression at 1 and 7 days. Subsequently, EA activated the VEGF/Notch pathway, increasing the expression of the downstream target protein Hes1, reversing EC death, and promoting angiogenesis. CONCLUSION: Our findings showed that EA plays a role in promoting angiogenesis following focal CIRI, and we hypothesized that this was due to the regulation of ECs by the EA-activated VEGF/Notch signaling pathway.

Clinical Factors Affecting the Recovery of Sensory Impairment After Cerebral Infarction: A Retrospective Study.

BACKGROUND: About 75% of patients with cerebral infarction suffer from sensory impairment in varying degrees. It prolongs the time for patients to resume normal life and work. The aim of this study was to retrospectively investigate the clinical characteristics affecting the recovery of sensory impairment. MATERIALS AND METHODS: This was a retrospective case-control study. Data of inpatients at the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine were investigated. We collected information on the patients with sensory disturbances after cerebral infarction. Cases were defined according to whether the National Institutes of Health Stroke Scale (NIHSS) and visual analogue scale (VAS) scores improved. A total of 1078 inpatients from January 1, 2019, to December 31, 2021, were screened. Among those, 187 cases included in this study were divided into no improvement and improvement groups. We compared the clinical characteristics affecting the rehabilitation of these patients. RESULTS: The number of patients aged between 63 and 73 years in the no improvement group were significantly higher ( P <0.05). The incidence of coronary heart disease and thalamus infarction was significantly higher in patients in the no improvement cohort ( P <0.05). Furthermore, coronary heart disease [odds ratio=0.466, 95% confidence interval (0.252, 0.863), P =0.015] and thalamic infarction [odds ratio=0.457, 95% confidence interval (0.230, 0.908), P =0.025] were the independent risk factors against the recovery of sensory disturbance after cerebral infarction. CONCLUSIONS: Patients with thalamus infarction and coronary heart disease may be more inclined to recover poorly from somatosensory deficits.

Acupuncture versus pharmacological conversation in treatment of atrial fibrillation in a randomized controlled trial: a systemic review and meta-analysis.

OBJECTIVE: This study aimed to investigate the effect of conventional drugs combined with acupuncture therapy on the conversion of sinus rhythm in patients with atrial fibrillation. METHODS: We searched databases, such as PubMed, Embase, WOS, Cochrane, CNKI (China National Knowledge Infrastructure), Wan fang Data, VIP, and CBM to collect data in randomized controlled trials of acupuncture included patients with atrial fibrillation. Publication time was limited from the beginning to May 15, 2021. The primary outcome is the number of participants who converted successfully. RESULTS: A total of 11 papers were included in this study. The combined effect indicated that acupuncture significantly effectively benefitted the patients with atrial fibrillation (RR = 1.208, 95% CI 1.123, 1.298, P < 0.001). Further subgroup analysis of persistent and paroxysmal atrial fibrillation and the timing of acupuncture suggested that the addition of acupuncture was not statistically significant in the treatment of persistent AF compared to the control group (RR = 1.147, 95% CI 0.811, 1.623 P = 0.147). The combination of acupuncture was more effective in paroxysmal AF RR = 1.148 (95% CI 1.064, 1.239) P < 0.001. In addition, when the acupuncture time was limited to 20 min, it had the best treatment effect (RR = 1.510, 95% CI 1.25, 1.82). CONCLUSIONS: The combination of pharmacological resuscitation with acupuncture significantly improved the conversion of paroxysmal atrial fibrillation compared to pharmacological resuscitation only. The most significant benefit was achieved with an acupuncture duration of < 20 min. Thus, the combination of acupuncture could be considered in clinical practice for the resuscitation of patients with atrial fibrillation.
