Objective: To optimize the preparation method of triptolide-nano-liposomes (TP-NLS). Methods High pressure homogeneous method was used to prepare TP-SLN. According to even design U7 (73), the preparation method of TP-SLN was optimized with the factors including weight ratio of phosphorlipid and cholesterol (A), quantity of Poloxamer 188 (B), and homogeneous pressure (C), using the encapsulation efficiency (EE), particle size, and Zeta potential of NLS as indexes. Results The optimum prescription of TP-NLS was A1B5C7, i.e. lipid matrix a:b was 6:1, the dosage of Poloxamer 188 was 1.3 g, and the homogeneous pressure was 70 MPa, high pressure homogeneous method for 15 min. The TP-NLS prepared with the optimal method had good appearance. The EE was 83.52%, the average particle size was 117 nm, and the Zeta potential was 31.7 mV. The TP-NLS solution was kept in avoiding light environment at 4 °C for 30 d, and the preservation stability was good. Conclusion The formula is reasonable and the preparation method of TP-NLS is feasible, which is valuable to further study.
The research of effective components of Chinese materia medica (CMM) is one of the key points of modernization of traditional Chinese medicine (TCM), is the core of interpreting overall efficacy and mechanism of TCM, and is the important foundation of realizing the safety, efficacy, and quality control of CMM. Previous studies mostly focused on the binary research mode of “component-effect”. However, in this paper, the triadic theory of “property-effect-component” was proposed and the research strategy and mode of exploring the mechanism, effective components, and quality markers (Q-Marker) of TCM were established based on the basic properties of TCM, basic concepts and terms of TCM theory and also related with the core contents of TCM theory including syndrome differentiation and treatment, rules of treatment, method of treatment, compatibility regularity, and drug property. The Yuanhu Zhitong Dropping Pills (YZDP) were taken as an example for demonstration research and corydaline, tetrahydropalmatine, protopine, imperatorin, and isoimperatorin were determined to be the Q-Marker of YZDP.

Objective According to the ICH guideline, the long-term stability and accelerated stability testing for Er-Zhi-Wan(water honey pills) has been carried out on the basis of the qualitative and quantitative analysis on multiple components in Er-Zhi-Wan by using UPLC-Q-TOF/MS method. In addition, the influence factors of the preparation(packing material and sealing process) were investigated by UPLC method. Methods The analysis was performed on an Acquity UPLC BEH C18 column (100 mm × 2.1 mm, 1.7 μm) with the mixture of acetonitrile-water-formic acid as mobile phase, the flow rate was 0.2 m L/min and MS scanning mode was positive and negative. According to the ICH guideline, the 18 months long-term stability [(25 ± 2) ℃, relative humidity (RH) of (60 ± 5)%], accelerated stability testing [(40 ± 2) ℃, RH of (75 ± 5)%], and influence factors of preparation(packing material and sealing process) for Er-Zhi-Wan(water honey pills) have been carried out by the UPLC method. Results A total of 20 chemical compounds(salidroside, wedelolactone, 10-hydroxyoleoside dimethyl ester, oleoside-11 methyl ester, loganic acid, echinacoside, nuezhengslaside, oleuropein acid, verbascoside/isoverbascoside, nuezhenoside, specnuezhenide, ligustroflavone, isomer of specnuezhenide, safghanoside F, isonuezhenide, nuezhenidic acid, oleuropein, nuezhenoside-G13, sinomenine, and 3-O-cis-p-coumaroyltormentic acid) were identified in the qualitative study. The content of these compounds was measured by the established quantitative and semi-quantitative research methods. In long-term stability testing, the 20 compounds were all remained stable. However, in the accelerated testing, the content of 11 chemical compounds (10-hydroxyoleoside dimethyl eser, echinacoside, nuezhengslaside, oleuropein acid, verbascoside, nuezhenide, specnuezhenide, ligustroflavone, nuezhenidic acid, nuezhenoside-G13, and sinomenine) decreased obviously. Taking soda-lime glass as the packaging material, the stability of Er-Zhi-Wan (water honey pills) was improved than the commercial package under the same sealing conditions. The airtightness of the packaging materials played a significant part on the pill's stability under different sealing conditions. Conclusion The study offers the scientific and technical support for the quality control and the clinical safety of the preparation in Chinese materia medica.
Objective Taking mesoporous silica nanoparticle (MSN) as carrier, to prepare curcumin (Cur)-MSN-solid dispersion (SD) for study on its effect on the dissolution rate and solubility of Cur. Methods MSN was prepared by condensation method and Cur-MSN-SD was obtained using solvent evaporation method. Then, Cur-MSN-SD was characterized with scanning electron microscope, nitrogen adsorption test, infrared spectrum analysis, and differential scanning calorimetry. Then the dissolution rate and solubility between Cur and Cur-MSN-SD were compared. Results The average pore diameter of prepared MSN was 2.737 nm, with the feature of typical mesoporous structure, and Cur was distributed in the channel. The cumulative dissolution rate and solubility of the drug were the best as the mass ratio of Cur to MSN was 1:4. Conclusion The Cur-MSN-SD prepared with the MSN as carrier could improve the cumulative dissolution rate and solubility of Cur, which provides an effective method for solving the water non-solubility of Cur.
Objective To study the molecule mechanism of salidroside inducing mesenchymal stem cells (MSCs) to directionally differentiate into neuronal cells via bone morphogenetic protein (BMP) and Notch signal pathways. Methods Experiments were divided into control, induced, and blocked groups. The technologies, such as immunofluorescence, real-time PCR, and Western blotting were used to analyze the effect of salidroside on cellular proliferation, morphosis, and BMP and Notch signal pathways. Results The immunofluorescence results showed that salidroside could affect cellular proliferation and induce MSCs to form the morphosis of neuronal cells. The positive rate of Notch1 and Jadge1 was significantly decrease to compare with the control (P < 0.05), real-time PCR results indicated that m RNA expression of Notch1 and Hes1 was obviously down-upregulated when treated with salidroside for 12—72 h (P < 0.05). However, Notch signal pathway was blocked with DAPT, a special inhibitor of Notch, the marker molecules of neuronal cells expression, such as neuron-specific enolase (NSE), microtubule associated protein 2(MAP2), and β-tubulin III, were significantly increased when cells were treated with salisroside (P < 0.05). The m RNA levels of Smad5 and Smad8 were up-regulated when cells were treated with salidroside for 12 h, expression of Smad1/5/8 protein was increased at 12 and 24 h. When BMP signal pathway was blocked with Noggin, a special inhibitor of BMP, NSE, MAP2, and β-tubulin III m RNA expression was decreased to compare with the salidroside induced group (P < 0.05); When Notch and BMP signal pathways were simultaneously blocked with DAPT and Noggin, MAP2 and β-tubulin III m RNA expression was increased more obviously than that of the blocked with Noggin. Meanwhile the expression of NSE and β-tubulin III protein was also up-regulated (P < 0.05). Conclusion Salidroside promotes neuron-like differentiation of MSCs by negatively regulating the Notch pathway and activating BMP signal pathway, it plays a vital role for salidroside to inhibit Notch pathway on affecting MSCs differentiation.
