Gouty arthritis （GA） is an inflammatory disorder caused by monosodium urate （MSU） crystal deposition， accompanied by elevated oxidative stress and aberrant release of inflammatory cytokines， resulting in joint tissue damage and intense pain. Nuclear factor E₂-related factor 2 （Nrf2）， a key transcription factor regulating the antioxidant defence system， exerts cytoprotective effects through dissociation from Kelch-like ECH-associated protein 1 （Keap1） and activates downstream antioxidant response element （ARE）-mediated pathways. It can upregulate the expression of heme oxygenase-1 （HO-1）， NADH quinone oxidoreductase 1 （NQO1）， superoxide dismutase （SOD）， and glutathione transferase （GST） to preserve redox homeostasis. Moreover， Nrf2 can suppress activation of NOD-like receptor protein 3 （NLRP3） inflammasomes， reduce pro-inflammatory cytokine production and release， modulate nuclear factor-κB （NF-κB） transcriptional activity， regulate gut microbiota balance， enhance mitophagy， and inhibit apoptosis， so as to reduce joint inflammation and pain and promote body recovery. This review systematically examined recent advancements in traditional Chinese medicine （TCM） for GA prevention and treatment via regulating the Nrf2 signaling pathway. It delineated Nrf2's molecular mechanisms and its role in GA pathogenesis and elucidated how TCM intervenes in multiple pathways including Keap1/Nrf2/ARE， Nrf2/HO-1（NQO1）， and Nrf2/NF-κB/NLRP3 to exert therapeutic effects. The study demonstrated that TCM monomers and compounds effectively counteract oxidative damage， attenuate inflammatory responses， promote autophagy， and inhibit apoptosis via regulating the Nrf2 signaling pathway. These findings not only clarify the scientific basis of TCM in GA treatment but also offer strategic insights for developing novel Nrf2-targeted anti-gout drugs.

Objective To evaluate the evidence and recommendations of the relevant clinical practice guidelines for the prevention and treatment of stroke published in the last five years. Methods The stroke and guideline-related key words and free words domestic computer retrieval platforms(China biomedical literature database,CNKI,and Yimaitong etc.),as well as foreign platforms(PubMed,NGC,GIN,etc.) were retrieved.The retrieval time limit ranged from January 2012 to May 2017.Appraisal of Guidelines for Research and Evaluation Ⅱ(AGREE Ⅱ)was used to assess the quality of the guidelines. Results A total of 9 490 documents were retrieved preliminarily and finally 16 articles were included. The average scoring rates of the 16 guidelines in the 6 fields of AGREE Ⅱ,including the scope and purpose,participants,rigor of the formulation,clarity of expression,applicability,and independence of the editors were 66.3%, 27.4%,23.0%,53.9%,18.8%,and 0%,respectively.The different guidelines all recommend that internal endarterectomy or carotid balloon dilatation and carotid artery stenting are used to extracranial carotid stenosis,while the treatment of vertebral artery stenting is recommended for extracranial vertebral artery stenosis.However,the intravascular interventional therapy is not recommended for intracranial arterial stenosis.The perioperative period of ischemic stroke intravascular intervention need to pay attention to the application of anti-platelet aggregation,anticoagulation,blood pressure,blood glucose,blood lipid management,and postoperative monitoring. For postoperative stent restenosis,especially after vertebral artery stenting,the guidelines recommend using drug-eluting stents,however,the dosage of heparin in intraoperative anticoagulation is still controversial.The intracranial aneurysm guidelines are more recommended for interventional therapy.The cerebral hemorrhage in different regions is recommended for different surgical procedures. Conclusions The guidelines in this field can reflect the key problems in clinical practice and keep up with the international concept.However,the quality of the methodology of the guidelines development needs to be improved. Some of them need to be updated and the recommendations should refer more evidence of the Chinese population.

Objective To evaluate the short-term outcome of local intraarterial thrombolysis in patients with acute ischemic stroke of the anterior circulation. Methods 24 patients with acute ischemic stroke of the anterior cir-culation within 8 hours were treated by local intraarterial thrombolysis. Arterial recanalization was divided into total, partial and occlusive respectively according to angiography. Evaluation of clinical outcome was performed on the 30th day after thrombolysis,and was classified as good for Modified Rankin Scale (MRS) scores of 0 to Ⅲ and poor for MRS scores of Ⅳ to Ⅵ. Results Total recanalization was obtained in 54.2 % of patients, partial recanalization in 25.0%. Clinical outcome was good in 15 patients (62.5%). Cerebral hemorrhage occurred in 4 patients (16.7%). Four patients died (16.7%). Conclusion Local intraarterial thrombolysis is an effective method for treatment of a-cute iachemic stroke of the anterior circulation. It needs further practice and long-term follow-up study on safety and long-term efficacy.
