Osteoarthritis （OA） and stroke are common clinical diseases that reduce patients' quality of life and place a burden on families and society. Ruyi Zhenbaowan， a classic prescription in Tibetan medicine， have the functions of clearing heat， awakening the brain and opening orifices， relaxing tendons and promoting meridian circulation， and eliminating yellow water. Clinically， they are used to treat osteoarthritis， post-stroke sequelae， neuropathic pain， and other related conditions. Modern pharmacological studies have demonstrated their anti-inflammatory， analgesic， and nerve-repairing effects. However， current research remains insufficient regarding the appropriate indications， timing， and efficacy of this medicine in treating relevant diseases. To enhance clinicians' understanding of this medicine and promote its standardized and rational clinical use， a panel of national experts， including clinical specialists， Tibetan medicine practitioners， pharmacologists， and methodologists， formulated this consensus based on clinical experience and evidence-based practice. The Cochrane systematic review framework， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system， and the nominal group method were employed to generate seven graded recommendations and 19 consensus-based suggestions. These recommendations clearly define the key points in the clinical application of Ruyi Zhenbaowan， including therapeutic indications， dosage and administration， treatment duration， and medication safety. The consensus specifically addresses the clinical efficacy， appropriate timing of administration， dosage strategies， treatment cycles， and combination medication strategies for treating osteoarthritis and stroke and provides an overview of safety considerations. The aim is to provide standardized guidance for hospitals and healthcare institutions nationwide to ensure the rational application of Ruyi Zhenbaowan in the treatment of osteoarthritis and stroke， reduce medication-related risks， and further leverage its clinical advantages. This consensus has been approved and issued by the China Association of Chinese Medicine， with the standard number GS/CACM 369-2024.

Objective To investigate the association between the pattern of carotid artery calcification and the prognosis of patients with acute cerebral infarction after 3 months of treatment. Methods A total of 112 patients who were diagnosed with acute ischemic stroke （AIS） in our hospital from March 2021 to September 2022 were enrolled as subjects. CT angiography was performed within 24 hours after admission， and the carotid artery was assessed in terms of calcification pattern （no calcification， intimal calcification， and medial calcification） and calcification load （low and high calcification）. After 7 days of treatment， CT reexamination was performed to evaluate hemorrhagic transformation and infarct volume. The patients were followed up for 3 months， and according to the modified Rankin Scale （mRS） score， they were divided into good prognosis group （82 patients with an mRS score of <3 points） and poor prognosis group （30 patients with an mRS score of ≥3 points）. Results Compared with the good prognosis group， the poor prognosis group had a significantly higher proportion of patients with an age of ≥70 years， a mean systolic blood pressure of ≥165 mmHg， a fasting blood glucose level of ≥7.5 mmol/L， an NIHSS score of ≥12 on admission， intimal calcification， medial calcification， high calcification， hemorrhagic transformation， and an infarct volume of ≥50 mm3 （P<0.05）. The multivariate logistic regression analysis showed that NIHSS score ≥12 on admission， intimal calcification， hemorrhagic transformation， and infarct volume ≥50 mm3 were risk factors for poor prognosis （P<0.05）. Conclusion Intimal calcification of the carotid artery may be associated with the poor short-term prognosis of AIS patients， which can be used as a new noninvasive indicator for predicting prognosis.

Chemotherapy is currently the mainstay of systemic management for triple-negative breast cancer (TNBC), but chemoresistance significantly impacts patient outcomes. Our research indicates that Doxorubicin (Dox)-resistant TNBC cells exhibit increased glycolysis and ATP generation compared to their parental cells, with this metabolic shift contributing to chemoresistance. We discovered that ALKBH3, an m¹A demethylase enzyme, is crucial in regulating the enhanced glycolysis in Dox-resistant TNBC cells. Knocking down ALKBH3 reduced ATP generation, glucose consumption, and lactate production, implicating its involvement in mediating glycolysis. Further investigation revealed that aldolase A (ALDOA), a key enzyme in glycolysis, is a downstream target of ALKBH3. ALKBH3 regulates ALDOA mRNA stability through m¹A demethylation at the 3'-untranslated region (3'UTR). This methylation negatively affects ALDOA mRNA stability by recruiting the YTHDF2/PAN2-PAN3 complex, leading to mRNA degradation. The ALKBH3/ALDOA axis promotes Dox resistance both in vitro and in vivo. Clinical analysis demonstrated that ALKBH3 and ALDOA are upregulated in breast cancer tissues, and higher expression of these proteins is associated with reduced overall survival in TNBC patients. Our study highlights the role of the ALKBH3/ALDOA axis in contributing to Dox resistance in TNBC cells through regulation of ALDOA mRNA stability and glycolysis.

Objective To investigate the protective effect of metformin against PM2.5-induced functional impairment of placental trophoblasts and explore the underlying mechanism.Methods Sixteen pregnant Kunming mice were randomly assigned into two groups(n=8)for intratracheal instillation of PBS or PM2.5 suspension at 1.5,7.5,and 12.5 days of gestation.The pregnancy outcome of the mice was observed,and placental zonal structure and vascular density of the labyrinth area were examined with HE staining,followed by detection of ferroptosis-related indexes in the placenta.In cultured human trophoblasts(HTR8/SVneo cells),the effects of PM2.5 exposure and treatment with metformin on cell viability,proliferation,migration,invasion,and tube formation ability were evaluated using CCK8 assay,EDU staining,wound healing assay,Transwell experiment,and tube formation experiment;the cellular expressions of ferroptosis-related proteins were analyzed using ELISA and Western blotting.Results M2.5 exposure of the mice during pregnancy resulted in significantly decreased weight and number of the fetuses and increased fetal mortality with a reduced placental weight(all P<0.001).PM2.5 exposure also caused obvious impairment of the placental structure and trophoblast ferroptosis.In cultured HTR8/SVneo cells,PM2.5 significantly inhibited proliferation,migration,invasion,and angiogenesis of the cells by causing ferroptosis.Metformin treatment obviously attenuated PM2.5-induced inhibition of proliferation,migration,invasion,and angiogenesis of the cells,and effectively reversed PM2.5-induced ferroptosis in the trophoblasts as shown by significantly increased intracellular GSH level and SOD activity,reduced MDA and Fe2+ levels,and upregulated GPX4 and SLC7A11 protein expression(P<0.05 or 0.01).Conclusion PM2.5 exposure during pregnancy causes adverse pregnancy outcomes and ferroptosis and functional impairment of placental trophoblasts in mice,and metformin can effectively alleviate PM2.5-induced trophoblast impairment.
