Neuroprotective effects of Longxue Tongluo Capsule on ischemic stroke rats revealed by LC-MS/MS-based metabolomics approach

Objective: The present study aimed to evaluate the therapeutic effect and explore the underlying mechanisms of Longxue Tongluo Capsule (LTC) on ischemic stroke rats. Methods: Twenty-six rats were randomly divided into four groups, including sham group, sham + LTC group, MCAO group, and MCAO + LTC group. Ischemic stroke rats were simulated by middle cerebral artery occlusion (MCAO), and LTC treatment group were orally administrated with 300 mg/kg of LTC once daily for seven consecutive days. LTC therapy was validated in terms of neurobehavioral abnormality evaluation, cerebral infarct area, and histological assessments. The plasma metabolome comparisons amongst different groups were conducted by UHPLC-Q Exactive MS in combination with subsequent multivariate statistical analysis, aiming to finding the molecules in respond to the surgery or LTC treatment. Results: Intragastric administration of LTC significantly decreased not only the neurobehavioral abnormality scores but also the cerebral infarct area of MCAO rats. The interstitial edema, atrophy, and pyknosis of glial and neuronal cells occurred in the infarcted area, core area, and marginal area of cerebral cortex were improved after LTC treatment. A total of 13 potential biomarkers were observed, and Youden index of 11 biomarkers such as LysoPC, SM, and PE were more than 0.7, which were involved in neuroprotective process. The correlation and pathway analysis showed that LTC was beneficial to ischemic stroke rats via regulating glycerophospholipid and sphingolipid metabolism, together with nicotinate and nicotinamide metabolism. Heatmap and ternary analysis indicated the synergistic effect of carbohydrates and lipids may be induced by flavonoid intake from LTC. Conclusion: The present study could provide evidence that metabolomics, as systematic approach, revealed its capacity to evaluate the holistic efficacy of TCM, and investigate the molecular mechanism underlying the clinical treatment of LTC on ischemic stroke.     

基于BDNF/TrkB/p-CREB信号通路探讨血府逐瘀胶囊促进神经再生防治卒中后抑郁的作用及机制

目的 探讨血府逐瘀胶囊对卒中后抑郁（post-stroke depression,PSD）大鼠抑郁症状的改善作用,并基于神经再生关键通路脑源性神经营养因子（brain derived neurotrophic factor,BDNF）/酪氨酸激酶受体B(tyrosine kinase receptor,TrkB)/磷酸化环腺苷酸应答元件结合蛋白（phosphorylated cAMP response element-binding protein,p-CREB）探讨其机制。方法 采用短暂大脑中动脉梗塞（transient middle cerebral artery occlusion,tMCAO）复合慢性不可预知应激（chronic unpredictable mild stimulation,CUMS）方法复制PSD大鼠模型。大鼠随机分为假手术组、模型组及血府逐瘀低、高剂量（0.43、0.86 g/kg）组和氟西汀（1.8 mg/kg）组,每组18只。连续给予药物干预28 d,利用神经功能评分、糖水偏好实验、旷场实验、强迫游泳实验考察血府逐瘀胶囊对PSD大鼠神经功能损伤以及抑郁症...

Pharmacokinetic aspects of rectal formulations of Temazepam

An in vitro/in vivo study was carried out with different rectal formulations of temazepam. Pharmacokinetic data were determined in a cross-over study in 10 volunteers after rectal administration of 10 mg temazepam as a polyethylene glycol based suppository (selected from in vitro data), a liquid-filled capsule and a micro-enema respectively, using oral administration of a liquid-filled capsule as a reference. Serum levels of temazepam indicate an instantaneous and complete release from the micro-enema (F_rel=0.94±0.21, C_max 205±36.9 g/l, t_max 0.49±0.31 hour) and a slower but complete release of temazepam from the suppository (F_rel=1.01±0.25, C_max 202±41.3 g/l, t_max 1.48±0.41 hour). A high interindividual variation in absorption profiles was observed after rectal administration of the liquid-filled capsule (F_rel 0.72±0.36, C_max 182±122 g/l, t_max 4.08±4.28 hour), which makes it less suitable for rectal use. The micro-enema and suppository appear to be useful as rectal formulations for temazepam.
