Abstract
Endothelial dysfunction greatly contributes to microcirculation disorder. The role of prostaglandin E1 (PGE1) in cerebral microcirculation was explored in vitro. LPS (0.5 or 1 μg/ml) was added to induce injury in human brain microvascular endothelial cells (HCMEC/D3). CCK-8 was applied to check viabilities of HCMEC/D3 before and after LPS treatment. Western blot witnessed the changes in protein expressions of inflammatory cytokines, IL-6 and TNF-α. Caspase-3/7 activity was analyzed and so were the protein expressions of pro-apoptotic gene BAX and anti-apoptotic gene Bcl-2. mRNA expressions of eNOS and GTPCH1 were evaluated by RT-qPCR. After overexpressing eNOS or GTPCH1 in LPS-induced HCMEC/D3 cells, viabilities, inflammatory cytokines, caspase-3/7 activity, and apoptosis-related genes were detected. The modulation of PGE1 in eNOS and GTPCH1 production, viability, inflammation, and apoptosis was investigated. The inhibitor of eNOS or GTPCH1 was introduced to examine impacts of eNOS or GTPCH1 could have on the PGE1 function. LPS decreased cell viabilities, eNOS and GTPCH1 expression, and promoted inflammation and apoptosis in HCMEC/D3 cells. Overexpressed eNOS or GTPCH1 promoted cell viabilities and suppressed inflammation and apoptosis. PGE1 enhanced viability and decreased inflammation and apoptosis in cells treated by LPS. PGE1 activated eNOS and GTPCH1 and inhibition of eNOS or GTPCH1 led to the attenuation of the protective functions of PGE1 in LPS-induced cells. PGE1 protected HCMEC/D3 cells from injuries induced by LPS by activation of eNOS and GTPCH1, suggesting that PGE1 might be used to help maintain cerebral microcirculation in future.

Comparative in vivo constituents and pharmacokinetic study in rats after oral administration of ultrafine granular powder and traditional decoction slices of Chinese Salvia. Biomed Chromatogr 2018; 33:e4385.

Abstract
Salvia miltiorrhiza, one of the most well-known herbal medicines, is commonly used for the treatment of coronary heart diseases in China. Besides traditional decoction slices (TDS), another relatively new product of S. miltiorrhiza, ultrafine granular powder (UGP; D90 < 45 μm), is also increasingly being used. In this paper, a UHPLC-LTQ-Orbitrap MS technique was developed for a metabolite profile study after oral administration of UGP and TDS of S. miltiorrhiza. The results showed that the number of in vivo absorbed compounds from UGP was much greater than that from TDS, and different types of products from S. miltiorrhiza will have different metabolic processes in vivo. Furthermore, a UHPLC-Q-Trap MS/MS method for simultaneously determining four tanshinones (tanshinone IIA, dihydrotanshinone I, tanshinone I and cryptotanshinone) was established and applied to assess the pharmacokinetics of the two types of products. All of the analytes displayed significant higher area under the concentration-time curve and peak concentration after oral administration of UGP than after TDS, indicating that ultrafine powder product could improve the bioavailability and absorption of cryptotanshinon,tanshinone II A,dihydrotanshinonE I and tanshinone I in vivo. The present study provides scientific information for further exploration of the pharmacology of these two types of S. miltiorrhiza and offers a reference for clinical administration of S. miltiorrhiza.

Abstract
Salvia miltiorrhiza, one of the major traditional Chinese medicines, is commonly used and the main active ingredients—tanshinones—possess the ability to improve renal function. In this paper, the UPLC-TQ/MS method of simultaneously determining four tanshinones—tanshinone IIA, dihydrotanshinone I, tanshinone I, and cryptotanshinone—was established and applied to assess the pharmacokinetics in normal and chronic renal failure (CRF) rat plasma. The pharmacokinetics of tanshinones in rats were studied after separately intragastric administration of Salvia miltiorrhiza ethanol extract (SMEE) (0.65 g/kg), SMEE (0.65 g/kg) combined with Salvia miltiorrhiza water extract (SMWE) (1.55 g/kg). The results showed Cmax and AUC0–t of tanshinone IIA, tanshinone I, cryptotanshinone reduced by 50%~80% and CLz/F increased by 2~4 times (p < 0.05) in model group after administrated with SMEE. Nevertheless, after intragastric administration of a combination of SMWE and SMEE, the Cmax and AUC0–t of four tanshinones were upregulated and CLz/F was downregulated, which undulated similarity from the model group to the normal group with compatibility of SMEE and SMWE. These results hinted that SMWE could improve the bioavailability of tanshinones in CRF rats, which provides scientific information for further exploration the mechanism of the combination of SMWE and SMEE and offers a reference for clinical administration of Salvia miltiorrhiza.
