Zuojinwan originated from Danxi′s Experiential Therapy (《丹溪心法》) in the Yuan dynasty. It is a representative prescription for the treatment of liver fire invading stomach syndrome, and is also one of the typical prescriptions of the anti-adjuvant method of traditional Chinese medicine (TCM). In this paper, the method of bibliometrics was used to systematically sort out the ancient books of Zuojinwan, and 729 relevant literature data were obtained. After certain retrieval and screening, 57 ancient books of TCM were finally obtained. The statistics and analysis were carried out from the aspects of prescription source, historical evolution, composition, functions, evolution of prescription meaning, prescription dose, and preparation and usage of Zuojinwan. It was found that Zuojinwan was composed of Coptis chinensis rhizoma and Euodia rutaecarpa fructus in a ratio of 6∶1. It was mainly used for the treatment of liver fire invading stomach syndrome. The symptoms included pain in chest and hypochondrium, vomiting and bitter mouth, noisy acid-swallowing, red tongue coating yellow, and pulse string number. Later medical records recorded that Zuojinwan was mostly consistent with the original prescription. It mainly treated various diseases caused by liver fire, including left by liver fire, including left hypochondriac pain, swallowing acid and vomiting acid, tendon hernia and lump, epigastric pain, bitter mouth pulse string, head pain, diarrhea, gonorrhea, cold and hot, abdominal pain, alcohol wet yellowing, silence of oral dysentery and so on. There was little controversy in the analysis of relevant prescriptions. In the past dynasties, pills was mainly used, which was consistent with the original prescription. In modern times, it is mainly water flooding for pills or steamed cakes for pills, warm boiling water to serve 6 g, taking 2-3 g per time, the history is basically the same. In this paper, through the excavation, collation and systematic analysis of the ancient literature of TCM that recorded Zuojinwan, we hope to provide the literature basis for the development, inheritance and utilization of this famous classical formulas.

In this study, an HPLC method was developed for simultaneous determination of seven alkaloids (cytosine, oxymatrine, N-oxysophocarpine, N-methylcytisine, sophoranol, matrine, and sophocarpine) and three flavonoids (trifolirhizin, fermononetin, and maackiain) from different samples of Sophorae Tonkinensis Radix et Rhizoma. Samples were analyzed on a Welch XtimateTM C₁₈ column (4. 6 mm× 250 mm, 5 μm) eluted with the mobile phase of acetonitrile (A) and 0.01 mol•L⁻¹ ammonium acetate solution (pH 8.0) (B) in a linear gradient mode as follows: 0-20 min,4%-14% A;20-30 min,14%-25% A;30-45 min,25%-40% A;45-65 min,40%-55% A;65-75 min,55% A. The flow rate of the mobile phase, the column temperature, and the PDA detector wavelength were set at 1.0 mL•min⁻¹, 30 ℃, and 225 nm, respectively. For the method validation, these ten compounds showed good separation and satisfactory linearity (r≥0.999 7) within the concentration ranges tested. The mean recoveries were in the range of 98.60% to 102.6% with the RSD (n=6) between 0.60% and 3.7%. This method was proved to be simple, accurate and repeatable. The quantitative results showed that there were significant differences in the contents of seven alkaloids and three flavonoids among the different samples. This result revealed that the quality of Sophorae Tonkinensis Radix et Rhizoma varied widely. This method could be used for the simultaneous determination of the multi-ingredients from Sophorae Tonkinensis Radix et Rhizoma, which might provide scientific evidences to evaluate/control the quality of Sophorae Tonkinensis Radix et Rhizoma, comprehensively.

Currently, chemotherapy is one of the main therapy for cancer. But the traditional antitumor drugs are systemic distribution in vivo, they are difficult to achieve an effective drug concentration in the tumor tissue and don't have the ability to distinguish normal cells and tumor cells by themselves, that cause systemic toxicity easily and can not meet the clinical needs. With the research on mesoporous silica nanoparticles (MSNs) deepening, more and more attention in the drug delivery system have been payed to in recent years, because of its unique physicochemical structure characteristics, it has the effect on specific targets, directly inhibits the tumor cell growth, reduces the side effects to normal cells, tissues and organs and can be long-term medication, etc. It is expected to be excellent carriers of antitumor drugs. MSNs application in the field of cancer treatment has now become a hot research field of medicine. In this paper, the latest research about MSNs in antitumor drugs targeting delivery system from 2008 to 2015 is summarized, including the application of MSNs separately in antitumor drug targeting, passive targeting, active targeting, physical or chemical conditions response targeting and other compound targeting drug delivery system. We expect it to provide a reference to the toxicity reducing and efficacy enhancing and further development of chemical medicine, natural medicine and monomeric compound of chinese herbal medicine.
