1.Investigation of the mechanism of action and identification of candidate traditional Chinese medicines for the treatment of ischemic stroke in the Danshen-Jiangxiang pair based on drug-target-disease association network.
Journal of Biomedical Engineering 2023;40(4):762-769
The therapeutic efficacy of Danshen and Jiangxiang in the treatment of ischemic stroke (IS) is relatively significant. Studying the mechanism of action of Danshen and Jiangxiang in the treatment of IS can effectively identify candidate traditional Chinese medicines (TCM) with efficacy. However, it is challenging to analyze the effector substances and explain the mechanism of action of Danshen-Jiangxiang from a systematic perspective using traditional pharmacological approaches. In this study, a systematic study was conducted based on the drug-target-symptom-disease association network using complex network theory. On the basis of the association information about Danshen, Jiangxiang and IS, the protein-protein interaction (PPI) network and the "drug pair-pharmacodynamic ingredient-target-IS" network were constructed. The different topological features of the networks were analyzed to identify the core pharmacodynamic ingredients including formononetin in Jiangxiang, cryptotanshinone and tanshinone IIA in Danshen as well as core target proteins such as prostaglandin G/H synthase 2, retinoic acid receptor RXR-alpha, sodium channel protein type 5 subunit alpha, prostaglandin G/H synthase 1 and beta-2 adrenergic receptor. Further, a method for screening IS candidates based on TCM symptoms was proposed to identify key TCM symptoms and syndromes using the "drug pair-TCM symptom-syndrome-IS" network. The results showed that three TCMs, namely Puhuang, Sanleng and Zelan, might be potential therapeutic candidates for IS, which provided a theoretical reference for the development of drugs for the treatment of IS.

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.

Objective: This study aimed to investigate the oral anticoagulant (OAC) usage among new-onset acute ischemic stroke (AIS) patients with nonvalvular atrial fibrillation (NVAF) in China, and to explore the possible influencing factors of influent anticoagulant therapy in these patients. Methods: The NVAF patients who experienced new-onset and non-fatal AIS from August 2011 to December 2018 in the China Atrial Fibrillation Registry (China-AF), were enrolled. The follow-up ended in December 2019. Information including patients' demographic characteristics, medical history, medication usage, which were collected before and after the index stroke, were analyzed. Patients were classified into OAC group or non-OAC group according to OAC usage within 3 months post stroke. Multivariate logistic regression analysis were conducted to calculate the odds ratios (ORs) of factors which might be associated with OAC usage within 3 months post stroke. Results: A total of 957 new-onset AIS patients were enrolled, 39.4% (377/957) patients were treated with OAC within 3 months after AIS. Covering by high-reimbursement-rate insurance (OR: 1.91, 95%CI: 1.28-2.86, P=0.002), higher number of concomitant drugs (1-2 types OR: 2.10, 95%CI: 1.36-3.23, P=0.001; ≥3 types OR: 2.31, 95%CI: 1.37-3.91, P=0.002) and 3-month-peri-stroke AF recurrence (OR: 3.34, 95%CI: 2.34-4.76, P<0.001) were associated with OAC usage within 3 months post stroke, while higher HASBLED score (OR: 0.49, 95%CI: 0.40-0.60, P<0.001) and pre-stroke antiplatelet usage (OR: 0.29, 95%CI: 0.20-0.43, P<0.001) were related to no OAC usage within 3 months post stroke. Conclusions: In China, the proportion of NVAF patients who initiated OAC therapy within 3 months after new-onset AIS is as low as about 39.4%. Factors related to the OAC usage within 3 months post stroke are 3-month-peri-stroke AF recurrence, number of concomitant drugs and patients with high-reimbursement-rate insurance coverage, but higher HASBLED score and pre-stroke antiplatelet usage are related to no OAC usage within 3 months post stroke.

To explore the potential effective components and mechanism of Zhishe Tongluo Capsules in the treatment of ischemic stroke via network pharmacology, molecular docking and cellular experiment. The chemical constituents of Zhishe Tongluo Capsules were found by TCMSP, BATMAN-TCM and literatures. The constituents-target network was predicted by BATMAN-TCM database. Key words such as cerebral stroke, ischemic stroke and cerebral ischemic stroke were used to search ischemic stroke related targets, and then Venny Map was constructed based on the targets of traditional Chinese medicine and the targets of ischemic stroke. The overlapping targets were imported into STRING database to establish the interaction network. Furthermore, the core targets were screened out by Cytoscape software. Go and KEGG enrichment analysis were performed through DVIAD database. The results showed a total of 193 potential chemical constituents, 985 drug targets and 6 035 disease targets. There were 631 potential targets, 44 core targets and 55 potential active components for treating ischemic stroke through Venny mapping. GO enrichment analysis mainly involved response to hypoxia and positive regulation of ERK1/ERK2. KEGG pathway enrichment analysis mainly involved cholinergic synapse, cAMP signaling pathway, and calcium signaling pathway. Molecular docking data revealed that TP53, EGFR, IL6, INS, TNF and SRC had a good capability to bind with their corresponding active components. To ensure the protective effect Zhishe Tongluo Capsules on the inflammation reaction, an in vitro model of lipopolysaccharide(LPS)-induced RAW264.7 cells was built. The contents of IL-1α, IL-1β, IL-6 and TNF-α in the supernatant were significantly decreased by enzyme linked immunosorbent assay(ELISA). The findings suggested that Zhishe Tongluo Capsules could prevent the injury of ischemic stroke by inhibiting the inflammation.

Ischemic stroke is the leading cause of death and disability in adults in China. Recent studies have shown that neutrophil extracellular traps play a crucial role in occurrence and development of ischemic stroke. This paper reviewed the literatures on NETs since the discovery of NETs more than a decade ago, and summarized the composition of NETs, the effects of NETs on stroke, the intervention targets of NETs, and the effects of traditional Chinese medicine on NETs. NETs are an important cause of brain injury after stroke. Platelets, peptidylarginine deiminase 4, reactive oxygen species and histones are the targets to regulate NET formation in stroke. There are few researches on traditional Chinese medicine targeting NETs for stroke. Studies on the intervention of traditional Chinese medicine mainly target on neutrophils, which are the main components of NETs, and platelets, which induce the formation of NETs. The paper provided a comprehensive overview of current studies of NETs in ischemic stroke, so as to provide new ideas for the treatment and drug development of ischemic stroke.

The present study aimed to systematically evaluate the efficacy and safety of Ginkgo biloba extract 50(GBE50) in the treatment of ischemic stroke. The databases including CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library were searched for randomized controlled trial(RCT) of GBE50 for the treatment of ischemic stroke reported between database inception and May 2020. The methodological quality of the included RCTs was evaluated via the Cochrane risk of bias tool. The RevMan 5.4 was used for Meta-analysis. Sixteen RCTs were included, involving 1 615 patients with acute ischemic stroke. Most of the included RCTs reported the methods of random sequence generation, but only two performed the concealment of random sequence. All RCTs failed in blinding. Two RCTs reported the information of cases lost to follow-up and drop-outs. Since the number was small, the baselines of groups remained balanced. All RCTs reported key outcomes of ischemic stroke, which made selective reporting bias in a low risk. Meta-analysis results revealed that GBE50 combined with routine therapies could effectively lower the score of the National Institutes of Health stroke scale(NIHSS) and restore cognitive function and daily activity in ischemic stroke patients. Compared with routine therapies, the combination is advantageous in treating patients with ischemic stroke. However, high-quality multicenter RCTs with large sample sizes are still required for verification.

OBJECTIVE:
To evaluate the efficacy and safety of Yangyin Yiqi Huoxue Granule (, YYHG) in the treatment of ischemic stroke (IS) patients with qi-yin deficiency and blood stasis syndrome (QYDBSS), and to explore its effective dosage.
METHODS:
The total of 288 patients were randomly assigned to the YYHG high-dose, YYHG low-dose, positive control (administered Xiaoshuantong Granule, XSTG, ), or placebo control (administered inert granule) groups (72 cases per group) by software-drived competitive block randomization. The trial was conducted for a 28-day period, with a 180-day follow-up period. The primary outcome was the comprehensive curative evaluation, and secondary outcomes were the National Institute of Health Stroke Scale (NIHSS) score, Barthel activities of daily living (ADL) index score, the quality of life index (QLI) score, and the Chinese medicine syndrome (CMS) score. All analyses were done on an intention-to-treat basis. The clinical safety was also assessed.
RESULTS:
The total of 288 participants were recruited between June 1, 2008 and September 30, 2009, and 287 patients received intervention; the treatment groups were well balanced at baseline. The comprehensive cure rates of YYHG high-dose, low-dose, positive and placebo control groups were 63.38%, 31.94%, 36.11% and 6.14%, respectively; there was a statistical difference between the two groups (P<0.01), while the high-dose YYHG treatment group was significantly higher than the other 3 groups (P<0.01). The improvement of NIHSS, ADL, QLI and CMS scores of the YYHG high-dose and low-dose groups was significantly better than that of the positive control group and the placebo control group (P<0.05). In terms of improving the classification of the NIHSS scale and the assessment of the ADL scale, the YYHG high-dose group was significantly better than the other three groups (P<0.05), and the YYHG low-dose group was better than the placebo control group (P<0.01). At the same time, except for the QLI score, the high-dose group was better than the low-dose group (P<0.05). In terms of safety, adverse reactions after YYHG treatment were generally mild (3.78%), and no serious adverse reactions have been reported.
CONCLUSION
YYHG is safe and effective in the treatment of IS patients with QYDBSS.

Headache is a common clinical complication of ischemic stroke. As a precursor of stroke, headache occurs repeatedly in the convalescent period of ischemic stroke, leading to secondary stroke and seriously hindering patients' rehabilitation. Currently, it is believed that the pathogenesis of ischemic stroke-related headache is associated with the abnormal release of vasoactive substances, high platelet aggregation, and stimulation of intracranial pain-sensitive structures. The active ingredients in traditional Chinese medicines(TCM) with the effects of activating blood to resolve stasis and clearing heat to release exterior can protect brain tissue and relieve headache by reducing the release of inflammatory cytokines, alleviating antioxidant stress, inhibiting neuronal apoptosis and so on. This paper introduces the research progress in the potential mechanism and TCM treatment of ischemic stroke-related headache, aiming to provide reference for further research and drug development of this complication.

Chinese Medical Journal 2021;134(22):2666-2674
BACKGROUND:
Intravenous thrombolysis (IVT) is an effective way for treating acute ischemic stroke (AIS). However, its effects have not been established among AIS patients with unclear stroke symptoms or with stroke onset for >4.5 h.
METHODS:
We searched PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials and Google Scholar databases for randomized controlled trials that compared IVT (IVT group) and placebo or usual care (control group [CG]) in AIS patients with disease onset for >4.5 h. The outcomes of interest included the favorable functional outcome (defined as modified Rankin Scale [mRS] scores 0-1) at 90 days, the functional independence (defined as mRS scores 0-2) at 90 days, proportion of patients with symptomatic intracerebral hemorrhage (sICH) and death at 90 days. We assessed the risk of bias using the Cochrane tool. Pre-specified subgroup analyses were performed by age (≤70 years or >70 years), National Institute of Health Stroke Scale (NIHSS, ≤10 or >10) and time window (4.5-9.0 h or >9.0 h).
RESULTS:
Four trials involving 848 patients were eligible. The risk of bias of included trials was low. Patients in the IVT group were more likely to achieve favorable functional outcomes (45.8% vs. 36.7%; OR 1.48, 95% CI 1.12-1.96) and functional independence (63.8% vs. 55.7%; OR 1.43, 95% CI 1.08-1.90) at 90 days, but had higher risk of sICH (3.0% vs. 0.5%; OR 5.28, 95% CI 1.35-20.68) at 90 days than those in the CG. No significant difference in death at 90 days was found between the two groups (7.0% vs. 4.1%; OR 1.80; 95% CI 0.97-3.34).
CONCLUSIONS
Use of IVT in patients with extended time window may improve their functional outcomes at 90 days, although IVT may induce increased risk of sICH. Care of these patients should well balance the potential benefits and harms of IVT.
