RESUMEN

PURPOSE OF REVIEW: Tension-type headaches (TTH) significantly diminish patients' quality of life and increase absenteeism, thereby imposing a substantial economic burden. Animal models are essential tools for studying disease mechanisms and drug development. However, until now, little focus has been placed on summarizing the animal models of TTH and associated mechanistic studies. This narrative review discusses the current animal models of TTH and related mechanistic studies to provide insights into the pathophysiological mechanisms of and treatments for TTH. RECENT FINDINGS: The primary method for constructing an animal model of TTH involves injecting a solution of pain relievers, such as adenosine triphosphate, nerve growth factor, or a high concentration of salt solution, into the neck to initiate harmful cervical muscle responses. This model enables the examination of the interaction between peripheral muscles and central sensitization, which is crucial for understanding the pathophysiology of TTH. Mechanistic studies based on this model have investigated the effect of the P2X receptor antagonist, P2X7 receptor blockade, the P2Y1 receptor agonist 2-MESADP, P2Y1 receptor antagonist MRS2179, nitric oxide synthase inhibitors, and acetylsalicylic acid. Despite notable advancements, the current model of TTH has limitations, including surgical complexity and the inability to replicate chronic tension-type headache (CTTH). To gain a more comprehensive understanding and develop more effective treatment methods, future studies should focus on simplifying surgical procedures, examining other predisposing factors, and establishing a model for chronic TTH. This will offer a deeper insight into the pathophysiological mechanism of TTH and pave the way for improved treatment approaches.

RESUMEN

To systematically search and sort out the clinical randomized controlled trial(RCT) on the prevention and treatment of acute cerebral infarction with traditional Chinese medicine(TCM) by using the method of evidence map, and to understand the evidence distribution of related studies. CNKI, Wanfang, VIP, CBM, PubMed, EMbase, Cochrane Library and Web of Science were retrieved from January 2016 to September 2020, and literatures related to the prevention and treatment of acute cerebral infarction with traditional Chinese medicine were included. Text description combined with table and bubble chart were used to analyze the distribution characteristics of evidence. A total of 1 102 clinical articles in recent five years were retrieved. The annual trend of clinical study publication, study size, TCM therapy category and main scheme, and study literature quality were analyzed. We find that TCM treatment of acute cerebral infarction has become a hot topic of clinical research, the number of literature showed a trend of increased year by year, various means of intervention of TCM in the treatment of the advantages of increasingly highlight. Follow-up clinical research should highlight the characteristics of TCM: in the analysis of outcome indicators; increase the neuropsychological patients after stroke and cognitive ability, and the theory of combined treatment of TCM disease when thoughts; At the same time, the quality of clinical research needs to be improved. At present, there is still a lack of unified standards for the production of evidence map. This study is the first to explore the application of evidence map to summarize and display the clinical research status of TCM treatment of acute cerebral infarction, and combine it with the setting of priority areas of TCM clinical research, so as to provide a reference basis for determining the priority topic selection of TCM treatment optimization research.

RESUMEN

To analyze the use of outcome indicators of randomized controlled trial(RCT) of acupuncture in the treatment of acute ischemic stroke in recent three years, so as to provide a basis for building a study on the core outcome indicators for the treatment of acute ischemic stroke with acupuncture. The RCTs of acupuncture treatment for acute ischemic stroke in recent three years were collec-ted through computer retrieval of eight Chinese and English databases and two clinical trial registries at home and abroad. Literature was screened out, and data was extracted. Risk of assessment bias tool Cochrane 6.1 was used for bias risk assessment, outcome indicators were summarized and analyzed. A total of 47 RCTs were included, and 3 studies were trials registration scheme. Outcome indicators were divided into 6 categories according to functional attributes, namely physical symptoms/signs, physical and chemical examination, quality of life, traditional Chinese medicine symptoms/syndromes, safety events and long-term prognosis. The study found that in addition to the common problems in previous studies covered by the status quo of outcome indicators selection of RCT of acupuncture in the treatment of acute ischemic stroke, there were also the other problems as follows: emphasis on macroscopic efficacy indicators but neglect of acupuncture specific indicators, lack of characteristic indicators and economic indicators of traditional Chinese medicine therapy, and unification of indicators measurement tool and measurement time point. In the future, the outcome indicators set for the treatment of acute ischemic stroke with acupuncture shall be established, and the core outcome indicators set shall be in line with the characteristics of traditional Chinese medicine treatment.

RESUMEN

There have been many clinical trials, systematic reviews/Meta-analysis proving that Xingnaojing Injection has a good clinical efficacy in treatment of cerebral ischaemic stroke, but with fewer comprehensive descriptions. In this study, an overview of systematic reviews/Meta-analysis of Xingnaojing Injection in treating cerebral ischaemic stroke was performed to provide current situation of evidences and basis for clinical practice. CNKI, Wanfang, VIP, CBM, EMbase, PubMed, Cochrane Library, Web of Science were retrieved through computers. A total of 6 literatures were included in this study. By AMSTAR-2 checklist and GRADE, the quality of included systematic reviews and the efficacy of Xingnaojing Injection were evaluated. The results of AMSTAR-2 checklist showed an extremely low quality for all of the 6 systematic reviews. According to the results of GRADE evaluation, among 55 outcomes, there were 2 outcomes with a medium quality, 4 outcomes with a low quality and 49 outcomes with an extremely low quality. The 6 systematic reviews reached a consistent conclusion that Xingnaojing Injection was effective in the treatment of cerebral ischaemic stroke. This therapy could improve the total efficacy, neurological deficit scores, hemodynamic and hemodynamic parameters. However, the methodolo-gical quality of all literatures was extremely low. The evidence levels of outcomes were between extremely low to medium. The effectiveness of Xingnaojing Injection in the treatment of cerebral ischaemic stroke still needs to be further verified by more high-quality studies. In the future, relevant clinical studies and systematic reviews/Meta-analysis shall be carried out in a strict accordance with relevant regulations.

RESUMEN

To overview the systematic reviews of Panax notoginseng saponins in the treatment of acute cerebral infarction. CNKI, CBM, Wanfang, VIP, PubMed, Cochrane Library and EMbase databases were retrieved to collect the systematic reviews of the efficacy of P. notoginseng saponins in the treatment of acute cerebral infarction. The retrieval time was from the time of database establishment to January 2021. After two researchers independently screened out the literature and extracted the data, AMSTAR-2 scale was used to evaluate the methodological quality of the included systematic reviews, GRADE system was used to grade the quality of evidences of the outcome indicators, and the efficacy evaluation was summarized. A total of 5 systematic reviews were included. AMSTAR-2 evaluation results showed that 3 items were relatively complete, while 4 items had a poor overall quality. P. notoginseng saponins combined with conventional Western medicine therapy was superior to single conventional therapy in the recovery of neurological function, enhancement of the total effective rate in clinic, and improvement of activities of daily living. GRADE evaluation results showed that the quality of evidence was from low quality to very low quality. In conclusion, in the treatment of acute cerebral infarction, P. notoginseng saponins can improve the clinical efficacy, with a good safety but a not high methodological quality and a low evidence quality. It is suggested that high-quality clinical studies shall be further carried out to provide evidence-based basis for the application of P. notoginseng saponins in the treatment of acute cerebral infarction.

RESUMEN

OBJECTIVE: To assess the efficacy and safety of PNS on antiplatelet therapy in the treatment of AIS. METHODS: We searched 7 literature databases and 2 clinical studies databases for randomized controlled studies (RCTs) evaluating PNS as an adjuvant therapy for AIS. Relevant studies were retrieved and screened, and data were extracted independently by two reviewers. The quality of the included studies was assessed using the Cochrane Risk Assessment Tool. Meta-analysis was carried out with the Rev Man 5.4 software. RESULTS: Of 8267 records identified, 43 RCTs met our inclusion criteria (n = 4170 patients). Patients assigned to PNS with conventional treatments (CTs) had improved functional independence at 90 days compared with those assigned to CTs alone (RR = 1.87, 95% CI = 1.37, to 2.55, P < 0.0001). Patients who received PNS combined with CTs showed significantly high improvements in neurological function among individuals with AIS on the neurologic deficit score (NDS) (MD CSS = -5.71, 95% CI = -9.55 to -1.87, P=0.004; MD NIHSS = -3.94, 95% CI = -5.65 to -2.23, P < 0.00001). The results also showed PNS contributed to a betterment in activities of daily living (ADL) on the Barthel index (MD day 10 BI = 4.86, 95% CI = 2.18, to 7.54, P < 0.00001; MD day 14 BI = 13.92, 95% CI = 11.46 to 16.38, P < 0.00001; MD day 28 BI = 7.16, 95% CI = 0.60, to 13.72, P < 0.00001). In addition, PNS, compared with CTs alone, could significantly improve overall response rate (ORR) (RR NIHSS = 1.20, 95% CI = 1.16, to 1.24, P < 0.00001; RR CSS = 1.15, 95% CI = 1.08, to 1.24, P < 0.0001), hemorheological parameters, maximum platelet aggregation rate (MPAR) (MD = -6.82, 95% CI = -9.62 to -4.02, P < 0.00001), platelet parameters (MD PLT = 4.85, 95% CI = 1.82 to 7.84, P=0.002; MD MPV = -0.79, 95% CI = -1.09 to -0.48, P < 0.00001), and serum CD62P (MD = -0.21, 95% CI = -0.29 to -0.13, P < 0.00001). The incidence of adverse reactions in PNS was lower than that in the control group (RR = 0.62, 95% CI = 0.39 to 0.97, P=0.04). Adverse reactions in the PNS were mild adverse reactions. CONCLUSION: PNS may be effective and safe in treating AIS on ameliorating neurological deficit, improving activities of daily living function, and enhancing antiplatelet effects. However, more high-quality evidence is needed before it can be recommended for routine antiplatelet therapy in patients with AIS.
