High-performance liquid chromatographic (HPLC) fingerprints were developed for identification of both lipophilic and hydrophilic components of the roots of Salvia miltiorrhiza and four related preparations. These samples were separated with an Agilent Zorbax Extend C(18) reserved-phase column (5 microm, 250 mm x 4.6 mm) by linear gradient elution using water-phosphoric acid (100:0.026, v/v) and acetonitrile as mobile phase. The flow rate was 0.8 ml/min and the detector wavelength was set at 280 nm. Mean chromatograms and correlation coefficients of samples were calculated by the software "Similarity Evaluation System for Chromatographic Fingerprint of TCM". The correlation coefficients of Danshen and Fufang Danshen tablets (FDT) samples were in the range of 0.352-0.993 and 0.768-0.987, respectively. The correlation coefficients of Compound Danshen dripping pills (CDDP), Danshen injection (DSI) and Xiangdan injection (XDI) samples were higher than 0.928, 0.850 and 0.960, respectively. It was the first time to identify 34 peaks by comparing with standard compounds and using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS(n)) technique. All results indicated that the developed fingerprint assay could be readily utilized as a quality control method for S. miltiorrhiza and its related preparations.

Tanshinone IIA (Tan IIA) is a lipophilic active constituent derived from the rhizomes and roots of (Danshen), a common Chinese medicinal herb. However, clinical applications of Tan IIA are limited due to its poor solubility in water. : To overcome this limitation, we developed a calcium alginate hydrogel (CA) as a hydrophilic carrier for Tan IIA, which significantly improved its solubility.

Developing a novel and potent adjuvant with excellent biocompatibility for immune response augmentation is crucial for enhancing vaccine efficacy. Here, we prepared a stable PLGA nanoparticle by encapsulating MnCl/Salvia miltiorrhiza polysaccharide (MS-PLGA) and employed it as an adjuvant in the model antigen OVA (MS-PLGA-OVA) to elicit potent immunity. The biological experiments indicated that the MS-PLGA-OVA could effectively recruit APCs to the injection site and provoke long-term antibodies.

The design and development of advanced surgical sutures with appropriate structure and abundant bio-functions are urgently required for the chronic wound closure and treatment. In this study, an integrated technique routine combining modified electrospinning with hot stretching process was proposed and implemented to fabricate poly(L-lactic acid) (PLLA) nanofiber sutures, and the Salvia miltiorrhiza Bunge-Radix Puerariae herbal compound (SRHC) was encapsulated into PLLA nanofibers during the electrospinning process to enrich the biofunction of as-generated sutures. All the PLLA sutures loading without or with SRHC were found to exhibit bead-free and highly-aligned nanofiber structure.

Background: The Beclin-1/Bcl-2 complex plays a pivotal role in regulating both autophagy and apoptosis in osteoblasts affected by osteoporosis. This study first investigates whether the Bushen Jianpi Huoxue Formula can enhance the cellular function of osteoblasts. Additionally, it initially explores the functional mechanism of Beclin-1/Bcl-2-related apoptosis.
