ObjectiveTo evaluate the clinical efficacy and safety of the Qishen Liuwei presoription for senile hypertension complicated with frailty （of Qi deficiency and blood stasis pattern， or deficiency of both spleen and kidney pattern）. MethodsA single-center， randomized controlled clinical trial design was employed in this study. Sixty-four eligible patients， treated at the Cardiology Outpatient Clinic of Dongfang Hospital， Beijing University of Chinese Medicine between June 2024 and February 2025， were randomly allocated into an observation group or a control group， with 32 patients in each group. Both groups received standard conventional antihypertensive therapy， while the observation group additionally received the Qishen Liuwei Formula （one dose per day， in separate servings in the morning and evening）. For both groups， a treatment course consisted of 4 weeks， followed by a 2-month follow-up period. Then， the primary indicator （Fried frailty phenotype scores）， along with secondary indicators including traditional Chinese medicine （TCM） syndrome scores and changes in blood pressure were observed before and after treatment. ResultsRegarding Fried frailty phenotype scores， the observation group exhibited significantly improved grip strength， 4.57 m walk time， the duration of weekly walks， ''effort required for any activity''， and ''inability to walk forward'' after treatment， while only the latter two indicators were significantly improved in the control group （P<0.05）. Compared with the control group， the observation group demonstrated significantly superior improvement in the duration of weekly walks， ''effort required for any activity''， and frailty （P<0.05）. For total TCM syndrome scores， both groups displayed significantly decreased total TCM syndrome scores （P<0.05） after treatment， and the decrease was more significant in the observation group （P<0.05）. Regarding office blood pressure， both groups showed significantly decreased diastolic blood pressure and mean arterial pressure after treatment， while the observation group also showed significantly decreased systolic blood pressure （P<0.05）. During treatment， one case of facial rash occurred in the observation group， representing an adverse reaction rate of 3.13% （1/32）. The rash resolved one week after discontinuation of medication. No adverse reactions occurred in the control group during treatment. No statistically significant difference was observed in the incidence of adverse reactions between the two groups. ConclusionFor senile hypertension complicated with frailty， the Qishen Liuwei presoription effectively improves physical activity， muscle strength， frailty-related symptoms， and TCM syndrome remission. When combined with Western medicine， the Formula contributes to stable blood pressure control and demonstrates a favorable clinical safety profile， indicating its clinical application potential.

Elemene is widely recognized as an effective anti-cancer compound and is routinely administered in Chinese clinical settings for the management of several solid tumors, including non-small cell lung cancer (NSCLC). However, its detailed molecular mechanism has not been adequately demonstrated. In this research, it was demonstrated that elemene effectively curtailed NSCLC growth in the patient-derived xenograft (PDX) model. Mechanistically, employing high-throughput screening techniques and subsequent biochemical validations such as microscale thermophoresis (MST), microRNA-145-5p (miR-145-5p) was pinpointed as a critical target through which elemene exerts its anti-tumor effects. Interestingly, elemene serves as a binding stabilizer for miR-145-5p, demonstrating a strong binding affinity (dissociation constant (K _D) = 0.39 ± 0.17 μg/mL) and preventing its degradation both in vitro and in vivo, while not interfering with the synthesis of the primary microRNA transcripts (pri-miRNAs) and precursor miRNAs (pre-miRNAs). The stabilization of miR-145-5p by elemene resulted in an increased level of this miRNA, subsequently suppressing NSCLC progression through the miR-145-5p/mitogen-activated protein kinase kinase kinase 3 (MAP3K3)/nuclear factor kappaB (NF-κB) pathway. Our findings provide a new perspective on revealing the interaction patterns between clinical anti-tumor drugs and miRNAs.
