The activation of the sirtuin1(SIRT1)/nuclear factor erythroid 2-related factor 2(Nrf2)/heme oxygenase 1(HO-1) pathway has been shown to mitigate oxidative stress-induced apoptosis and mitochondrial damage by reducing reactive oxygen species(ROS) levels. Clinical trials have demonstrated that Zhongfeng Xingnao Liquid(ZFXN) ameliorates post-stroke cognitive impairment(PSCI). However, the underlying mechanism, particularly whether it involves protecting mitochondria and inhibiting apoptosis through the SIRT1/Nrf2/HO-1 pathway, remains unclear. This study employed an oxygen-glucose deprivation(OGD) cell model using SHSY5Y cells and induced PSCI in rats through modified bilateral carotid artery ligation(2VO).The effects of ZFXN on learning and memory, neuroprotective activity, mitochondrial function, oxidative stress, and the SIRT1/Nrf2/HO-1 pathway were evaluated both in vivo and in vitro. Results indicated that ZFXN significantly increased the B-cell lymphoma 2(Bcl2)/Bcl2-associated X(Bax) ratio, reduced terminal deoxynucleotidyl transferase-mediated d UTP nickend-labeling(TUNEL)+ cells, and markedly improved cognition, synaptic plasticity, and neuronal function in the hippocampus and cortex. Furthermore, ZFXN exhibited potent antioxidant activity, evidenced by decreased ROS and malondialdehyde(MDA) content and increased superoxide dismutase(SOD), catalase(CAT), and glutathione(GSH) levels. ZFXN also demonstrated considerable enhancement of mitochondrial membrane potential(MMP), Tom 20 fluorescence intensity, adenosine triphosphate(ATP) and energy charge(EC) levels, and mitochondrial complex Ⅰ and Ⅲ activity, thereby inhibiting mitochondrial damage. Additionally,ZFXN significantly increased SIRT1 activity and elevated SIRT1, nuclear Nrf2, and HO-1 ***, these effects were substantially counteracted when SIRT1 was suppressed by the inhibitor EX-527 in vitro. In conclusion, ZFXN alleviates PSCI by activating the SIRT1/Nrf2/HO-1 pathway and preventing mitochond

Monitoring critical quality attributes in pharmaceutical manufacturing ensures that the final product meets specified requirements. Process analysis allows for appropriate modifications and customization of pharmaceutical design from formulation to production. The laborious sample presentation and throughput have stimulated the development of in-process spectroscopy methods for pharmaceutical analysis. Raman spectroscopy has demonstrated the unique advantages of rapid and nondestructive analysis, good interpretability, and effective moisture interference avoidance. The Raman imaging technique can obtain spatial and chemical information that is useful for characterizing drug quality. This article describes the applications of Raman spectroscopy and imaging techniques in pharmaceutical analysis. It covers the monitoring of crystal forms and particle size distribution, quantification of active pharmaceutical ingredients, evaluation of contents uniformity, prediction of dissolution profiles in solid preparations, identification of counterfeit drugs, and applications in reverse engineering and process analytical technology. Moreover, the challenges and prospects are proposed to facilitate the continued development of Raman spectroscopy and imaging techniques, providing necessary references for further research in this field.
