1.Thrombolysis in acute ischemic stroke: issues and options.
Journal of Zhejiang University. Medical sciences 2014;43(1):1-6
China is one of the countries with highest incidence of stroke in the world. However, the rate of intravenous thrombolysis for ischemic stroke is extremely low in China, which is related to traditional triage system and inefficient management, the potential of hemorrhagic transformation, and narrow therapeutic time window. In order to improve the clinical implementation of thrombolysis, it is necessary to look at the related issues and to refine the therapeutic protocol according to the international experiences. Careful screening of eligible patients is crucial to reduce the rate of symptomatic intracranial hemorrhage. The advanced penumbral imaging is believed to enhance patient selection and extend the therapeutic time window. In addition, endovascular therapy is increasingly utilized to raise the recanalization rate. All these measures would enhance the improvement of the clinical management for acute stroke patients.

OBJECTIVE:
To investigate the effect of working time on the prognosis of patients with ischemic stroke undergoing intravenous thrombolysis.
METHODS:
Clinical data of 3050 patients with ischemic stroke received intravenous thrombolysis from 71 hospitals in Zhejiang Province during June 2017 and September 2018 were retrospective analyzed. Whole day of Saturday and Sunday were defined as weekend; whole day of Monday to Friday were defined as weekdays; Monday to Friday 8:00-17:00 were defined as daytime of weekdays; Monday to Friday 17:01-07:59 on next day were defined as nights of weekdays; unconventional working time were defined as weekend and nights of weekdays. Good outcome was defined as mRS 0-2 at 3 months. Univariate analyses of baseline and prognostic variables in group of weekend and weekdays, nights of weekdays and daytime of weekdays, unconventional working time and daytime of weekdays were performed. Binary logistic regression was used to investigate whether weekend, nights of weekdays and unconventional working time were independent predicting factors of outcome after intravenous thrombolysis, respectively.
RESULTS:
There was no difference in 7-day mortality, 3-month mortality and good outcome at 3-month between weekend group and weekdays group, nights of weekdays group and daytime of weekdays group, unconventional working time group and daytime of weekdays group (all >0.05). Binary logistic regression results showed that weekends, nights of weekdays and unconventional working time were not independent predicting factors for outcome after intravenous thrombolysis (all >0.05).
CONCLUSIONS
The working time has not affected the outcomes of patients with ischemic stroke undergoing intravenous thrombolysis in studied hospitals of Zhejiang province.

4.Research progress of ion channels relating to cerebral ischemic diseases and prevention and treatment with traditional Chinese medicine.
China Journal of Chinese Materia Medica 2020;45(21):5110-5116
Cerebral ischemia is a series of clinical symptoms and signs of cerebral ischemia, hypoxia and neuronal damage caused by cerebral artery stenosis or occlusion due to atherosclerosis or thrombosis, which seriously affects human health and quality of life. Cerebral ischemia involves the cascade reaction of the "neurovascular unit" system, and finally affects the normal physiological function of nerve cells and produces a series of pathological changes. And the changes in the structure and function of various ion channels in the cell membrane play an important role during this process. This article illustrates the changes in the ion channel associated with ce-rebral ischemic diseases, such as the potassium ion channels, sodium ion channels, calcium channels and other relevant channels, like AQP, TRPM2, TRPM7, TRPV4, ASICs, Cl~- channel, and explores the intervention effect of traditional Chinese medicine in prevention and treatment of cerebral ischemic diseases from the perspective of ion channels, in order to provide references for potential targets involving in drug development for the future prevention and treatment of cerebral ischemic diseases.

Methane is the simplest hydrocarbon, consisting of one carbon atom and four hydrogen atoms. It is abundant in marsh gas, livestock rumination, and combustible ice. Little is known about the use of methane in human disease treatment. Current research indicates that methane is useful for treating several diseases including ischemia and reperfusion injury, and inflammatory diseases. The mechanisms underlying the protective effects of methane appear primarily to involve anti-oxidation, anti-inflammation, and anti-apoptosis. In this review, we describe the beneficial effects of methane on different diseases, summarize possible mechanisms by which methane may act in these conditions, and discuss the purpose of methane production in hypoxic conditions. Then we propose several promising directions for the future research.

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.

7.Herbal Medicine in Ischemic Stroke: Challenges and Prospective.
Chinese journal of integrative medicine 2018;24(4):243-246
Herbal medicines, mainly of plant source, are invaluable source for the discovery of new therapeutic agents for all sorts of human ailments. The complex pathogenesis of stroke and multifactorial effect of herbal medicine and their active constituents may suggest the promising future of natural medicine for stroke treatment. Anti-oxidant, anti-inflammatory, anti-apoptotic, neuroprotective and vascular protective effect of herbal medicines are believed to be efficacious in stroke treatment. Herbs typically have fewer reported side effects than allopathic medicine, and may be safer to use over longer period of time. Herbal medicines are believed to be more effective for the longstanding health complaints, such as stroke. Several medicinal plants and their active constituents show the promising results in laboratory research. However failure in transformation of laboratory animal research to the clinical trials has created huge challenge for the use of herbal medicine in stroke. Until and unless scientifically comprehensive evidence of the efficacy and safety of herbal medicine in ischemic stroke patients is available, efforts should be made to continue implementing treatment strategies of proven effectiveness. More consideration should be paid to natural compounds that can have extensive therapeutic time windows, perfect pharmacological targets with few side effects. Herbal medicine has excellent prospective for the treatment of ischemic stroke, but a lot of effort should be invested to transform the success of animal research to human use.

The naturally-occurring dipeptide carnosine (beta-alanyl-L-histidine) is found exclusively in animal tissues, such as brain and skeletal muscle tissues. Carnosine is a potent hydrophilic antioxidant, antiglycating agent, reactive oxygen species scavenger and pH-buffer. Recent reports suggest that carnosine has potential therapeutic applications in many diseases of central nervous system, such as Alzheimer's disease, Parkinson's disease and cerebral ischemic diseases. To investigate the relationship between carnosine and diseases of central nervous system, and to research and develop carnosine drugs will shed light on a new way for treatment of diseases of central nervous system.

Angong Niuhuang Pills, a classical formula in traditional Chinese medicine, are lauded as one of the "three treasures of febrile diseases" and have been widely used in the treatment of diverse disorders with definite efficacy. However, there is still a lack of bibliometric analysis of research progress and development trend regarding Angong Niuhuang Pills. Research articles on Angong Niuhuang Pills in China and abroad(2000-2022) were retrieved from CNKI and Web of Science. CiteSpace 6.1 was used to visualize the key contents of the research articles. In addition, the research status of Angong Niuhuang Pills was analyzed by information extraction to allow insight into the research trends and hotspots about Angong Niuhuang Pills. A total of 460 Chinese articles and 41 English articles were included. Beijing University of Chinese Medicine and Sun Yat-Sen University were the research institutions that have published the largest amount of research articles in Chinese and English. The keyword analysis showed that the Chinese articles focused on cerebral hemorrhage, stroke, neurological function, coma, cerebral infarction, craniocerebral injury, and clinical application, while the English articles focused on the mechanisms of cerebral ischemia, stroke, heavy metal, blood-brain barrier, and oxidative stress. Stroke, blood-brain barrier, and oxidative stress were presumably the research hotspots in the future. At present, the research on Angong Niuhuang Pills is still in the developing stage. It is necessary to highlight the in-depth research on the active components and mechanism of action and carry out large-scale randomized controlled clinical trials to provide references for the further development and application of Angong Niuhuang Pills.

In recent years, more and more research shows that the pharmacokinetic parameter of traditional Chinese medicine can be affected by the disease states. It's possible that drug metabolic enzymes, transporters, cell membrane permeability and the change of microbes group could be interfered with physiological and pathological changes, which enables the pharmacokinetics of traditional Chinese medicine in the body to be altered, including the process of absorption, distribution, metabolism and excretion, and then the pharmacokinetic parameters of traditional chinese medicine are altered. It's found that investigating the pharmacokinetic of traditional Chinese medicine in the pathological state is more useful than that of in normal state because the great part of traditional Chinese medicine is mainly used to treat disease. This article reflects the latest research on the pharmacokinetic of traditional Chinese medicine in the disease state such as diabete, cerebral ischemia, liver injury, inflammatory disease, nervous system disorders and fever in order to provide certain reference for clinicians designing reasonable administration dose.
