Abstract
To reconstruct and restore the functions of the male urethra is a challenging task for urologists. The acellular matrix graft currently used in the clinics is mono-functional and may cause a series of complications including stricture, fibrosis, and stone formation. As a result, such graft materials cannot meet the increasing demand for multifunctionality in the field of urethral tissue engineering. In this context, a multifunctional urethral patch is designed for the repair of urethral defects by mixing protocatechualdehyde (PCA) with small intestinal submucosa (SIS) under an alkalin condition to allow cross linking. As shown, the PCA/SIS patch possesses excellent biocompatibility, antioxidant activity, and anti-inflammatory property. More importantly, this patch can remarkably promote the adhesion, proliferation, and directional extension of rabbit bladder epithelial mucous cells (R-EMCs) as well as rabbit bladder smooth muscle cells (R-SMCs), and upregulate the expression of cytokeratin in the EMCs and contractile protein in the SMCs in vitro. In vivo experiments also confirm that the PCA/SIS patch can significantly enhance scarless repair of urethral defects in rabbits by facilitating smooth muscle regeneration, reducing excessive collagen deposition, and accelerating re-epithelialization and neovascularization. Taken together, the newly developed multifunctional PCA/SIS patch provides a promising candidate for urethral regeneration.

Abstract
Salvianolic acid B (SAB) is a widely used cardioprotective agent, while its clinical application was limited by poor intestinal absorption and low oral bioavailability. In this study, SAB phospholipid complex (SP) was first prepared to improve the lipophicity of SAB and then combined with D-glucose to further enhance intestinal absorption. Compared with free SAB, SP or the mixture of SAB and D-glucose, combination of SP and D-glucose showed higher intestinal absorption evidenced by increased effective permeation coefficient (Peff) in the in situ single-pass intestinal perfusion (SPIP) assay. Subsequently, SP and D-glucose at mass ratio of 1:6, with the highest Peff of SAB, were chosen for the preparation of complexed pellets to improve oral absorption efficiency of SAB. As expected, the obtained pellets significantly enhanced oral bioavailability of SAB in the pharmacokinetic study characterized by increasing Cmax and AUC0-t of SAB by 14.88-fold and 5.02-fold than free SAB, respectively. In conclusion, combination of D-glucose in SP pellets can effectively improve the intestinal absorption and oral bioavailability of SAB.

Abstract
Traditional Chinese medicines (TCMs), with a history of thousands of years, are widely used clinically with effective treatment. However, the drug delivery systems (DDSs) for TCMs remains major challenges due to the characteristics of multi-components including alkaloids, flavones, anthraquinones, glycosides, proteins, volatile oils and other types. Therefore, the novel preparations and technology of modern pharmaceutics is introduced to improve TCM therapeutic effects due to instability and low bioavailability of active ingredients. Salviae Miltiorrhizae Radix et Rhizoma, the radix and rhizomes of Salvia miltiorrhiza Bunge (Danshen in Chinese), is a well known Chinese herbal medicine for protecting the cardiovascular system, with active ingredients mainly including lipophilic tanshinones and hydrophilic salvianolic acids. In this review, this drug is taken as an example to present challenges and strategies in progress of DDSs for TCMs. This review would also summary the characteristics of active ingredients in it including physicochemical properties and pharmacological effects. The purpose of this review is to provide inspirations and ideas for the DDSs designed from TCMs by summarizing the advances on DDSs for both single- and multi-component from Danshen.

Abstract
Background:
Tanshinone IIA (TIIA), protocatechuic aldehyde (PA), danshensu (DSS), salvianolic
acid B (SAB) and hydroxysafflor yellow A (HSYA) are the major components of Salvia miltiorrhiza
Bge. (Danshen) and Carthamus tinctorius L. (Honghua) herbal pair. These active components
may contribute to the potential synergistic effects of the herbal pair.
Objective:
This study aimed to investigate the metabolites of TIIA, PA, DSS, SAB and HSYA in
zebrafish, and to explore the influence of HSYA on the metabolism of TIIA, PA, DSS, and SAB.
Method:
48 h post-fertilization zebrafish embryos were exposed either to each compound alone, TIIA
(0.89 μg/mL), PA (0.41 μg/mL), DSS (0.59 μg/mL), SAB (2.15 μg/mL), and HSYA (1.83 μg/mL) and
in combination with HSAY (1.83 μg/mL). The metabolites of TIIA, PA, DSS, SAB, and HSYA in
zebrafish were characterized using high-performance liquid chromatography/tandem mass spectrometry
(HPLC-MS/MS) and quantitatively determined by HPLC-MS with single and combined exposure.
Results:
Among the 26 metabolites detected and characterized from these five compounds, methylation,
hydroxylation, dehydrogenation, hydrolysis, sulfation and glucuronidation were the main phase I
and phase II metabolic reactions of these compounds, respectively. Furthermore, the results showed
that HSYA could either enhance or reduce the amount of TIIA, PA, DSS, SAB, and their corresponding
metabolites.
Conclusion:
The results provided a reference for the study on drug interactions in vivo. In addition, the
zebrafish model which required much fewer amounts of test samples, compared to regular mammal
models, had higher efficiency in predicting in vivo metabolism of compounds.

Abstract
The importance of drug dosing time in pharmacokinetics, pharmacodynamics, and toxicity is receiving increasing attention from the scientific community. In spite of mounting evidence that circadian oscillations affect drug absorption, distribution, metabolism, and excretion (ADME), there remain many unanswered questions in this field and, occasionally, conflicting experimental results. Such data arise not only from translational difficulties caused by interspecies differences but also from variability in study design and a lack of understanding of how the circadian clock affects physiological factors that strongly influence ADME, namely, the expression and activity of drug transporters. Hence, the main goal of this review is to provide an updated analysis of the role of the circadian rhythm in drug absorption, distribution across blood-tissue barriers, metabolism in hepatic and extra-hepatic tissues, and hepatobiliary and renal excretion. It is expected that the research suggestions proposed here will contribute to a tissue-targeted and time-targeted pharmacotherapy.

Abstract
BACKGROUND Danshen is a first-line traditional Chinese medicine derived from Salvia miltiorrhiza Bunge consisting mainly of tanshinone IIA, tanshinol, protocatechuic aldehyde, and salvianolic acid B, it is widely used to treat cardiovascular diseases based on the synergistic effect of its multiple active components. Recent studies have indicated that the overall effect of traditional Chinese medicine is closely related to the in vivo coexistence of a variety of active components. HYPOTHESIS The prolongation of the coexistence of the four active components in Danshen in vivo by regulating their pharmacokinetic processes may contribute to better efficiency. METHODS/STUDY DESIGNS Individual sustained-release pellets of the four main active components in Danshen were respectively prepared according to the optimised formulations developed in our previous studies to modulate their in vivo processes, in which the desired release profiles of each kind of sustained-release pellets for formulation optimisation were calculated based on the point-area deconvolution and circadian rhythm of variant angina. The four kinds of sustained-release pellets were filled into capsules on the basis of the original weight ratio of the four active components in purified Salvia miltiorrhiza extract for further in vitro release and pharmacokinetic and pharmacodynamic investigations. RESULTS The release behaviours of the combined Danshen capsules composed of the four kinds of sustained-release pellets were evaluated in three media with different pH levels (pH 1.2, 6.8, and pure water). The release profiles of each kind of sustained-release pellets in pH 6.8 PBS and pH 1.2 HCl were similar to the release profile of those in pure water (similarity factors f2 > 50). Pharmacokinetic studies revealed that the four kinds of sustained-release pellets in the combined Danshen capsules possessed the same Tmax and similar and extended MRT. Moreover, pharmacodynamic studies indicated that the combined Danshen capsules had much better anti-angina effects than commercial Danshen capsules according to comprehensive evaluations via electrocardiogram, serum index (CK-MB, cTn-I, ET, and NO), myocardial oxidative damage, and myocardial pathologic biopsy. CONCLUSION Sustained-release preparations can markedly prolong the in vivo coexistence of multiple components in Danshen to enhance their overall effects, which provides a potent strategy for developing the combination therapy of traditional Chinese medicine.

Abstract
The objective of this study was to prepare ibuprofen enteric-coated sustained-release pellets (IB-SRPs) and codeine phosphate immediate-release pellets (CP-IRPs) to play a synergistic role in analgesia. The pellets were developed by extrusion-spheronization and fluidized bed coating technology. The single-factor investigation was used to determine the optimal prescription and process. The sustained-release membrane of IB-SRPs was water-insoluble ethyl cellulose (EC), triethyl citrate (TEC) was used as plasticizer, and hydroxypropyl methylcellulose (HPMCP) was chose as porogen. Besides, the immediate-release layer of CP-IRPs was gastric-soluble coating film. The ibuprofen and codeine phosphate compound capsules (IB-CP SRCs) were prepared by IB-SRPs and CP-IRPs packed together in capsules with the optimum doses of 200 and 13 mg, respectively. The prepared pellets were evaluated by scanning electron microscopy and dissolution test. Pharmacokinetic studies in beagle dogs indicated that the optimized IB-CP SRCs had smaller individual differences and better reproducibility comparing with commercial available tablets. Additionally, IB-CP SRCs achieved consistency with in vivo and in vitro tests. Therefore, IB-CP SRCs could play a great role in rapid and long-term analgesic.
