[Study on effect of aqueous extracts from aconite on "dose-time-toxicity" relationships in mice hearts].
To study the effect of single administration of aqueous extracts from aconite on "dose-toxicity" relationship and "time-toxicity" relationship of mice hearts, through changes in electrocardiogram (ECG) and serum biochemical indexes. ⋯ Single oral administration of different doses of aqueous extracts from aconite could cause different degrees of heart injury at different time points, with a certain dose dependence. Its peak time of toxicity is at 60 min after the administration of aqueous extracts from aconite.

[Study on medication regularity of traditional Chinese medicines in treating attention deficit hyperactivity disorder based on data mining].
In this study, efforts were made to collect 88 traditional Chinese medicine (TCM) prescriptions for treating ADHD from public literatures, establish a medication database and conduct data mining on the efficacy, properties, tastes, meridian entries and compatibility regularity of TCMs by using frequency analysis, association rules analysis and cluster analysis. The results showed 33 herbs with a high frequency (≥ 10%). The top 12 frequently applied ADHD herbs were respectively Acori Tatarinowii Rhizome, Polygalae Radix, Prepared Rehmanniae Radix, Os Draconis, Glycyrrhizae Radix et Rhizome, Poria, Concha Ostreae, Testudinis Carapacis et Plastri, Paeoniae Alba Radix, Schisandrae Fructus Chinensis, Fructus Corni, Dioscoreae Rhizoma. ⋯ Eight highly frequent cluster prescriptions were summarized based on the cluster analysis. This study indicates that basic TCM prescriptions for treating ADHD were principally composed of tonics (nourishing liver and kidney, invigorating heart and spleen) and tranquilization, which were supplemented with herbs for calming liver, clearing heat, promoting qi-circulation, promoting blood-circulation, reducing phlegm and calming endogenous wind. The combination of multiple data mining techniques can reflect the clinical medication regularity of herbs for treating ADHD in an overall and objective manner.

[Study on anti-inflammation effect and involved mechanism of Guizhi Fuling capsule and its active complex].
The aim of this study was to investigate the anti-inflammatory effect of Guizhi Fuling capsule and its active complex (consistent of 15 active compounds) on LPS-induced RAW264. 7 cells. The effect of Guizhi Fuling capsule and its active complex on cell viability in RAW264. 7 cells were determined by MTT assay. The inhibitory effect of Guizhi Fuling capsule and active complex on the releasing of IL-1β, TNF-α and PGE2 induced by LPS in RAW264. 7 cells was detected by ELISA assay. ⋯ Moreover, the expression of IL-1β and mPGES-1 was decreased after Guizhi Fuling capsule and active complex treatment, which might contribute to the inhibitory effect of Guizhi Fuling capsule in the releasing of IL-1β, TNF-α and PGE2. This study provided the evidence that Guizhi Fuling capsule and active complex remarkably inhibited the releasing of IL-1β, TNF-α and PGE2induced by LPS in RAW264. 7 cells by reducing the expression IL-1β and mPGES-1. This study provided an experimental basis of Guizhi Fuling capsule for the treatment of inflammation and a theoretical basis for the development of effective compounds of Guizhi Fuling capsule.

Meta Analysis[Preliminary study on general safe medication regularity of Chinese patent orthopedic medicines based on adverse reaction/event literature analysis].
Chinese patent orthopedic medicines feature complex components, mainly including desperate and toxic herbal pieces, narrow safety window, more clinical contraindications and frequent adverse drug reaction/events (ADR/ADE). To study the general safe medication regularity of Chinese patent orthopedic medicines, define key points in the medication education and ensure rational clinical medication, the authors took 80 types of commonly used Chinese patent orthopedic medicines as the study objects, collect 237 cases from 164 ADR/ADE documents through a system retrieval strategy, make a multidimensional literature analysis to determine the common risk factors for safe and rational medication of Chinese patent orthopedic medicines and establish an ADR/ADE prevention regularity. ⋯ Fourth, emphasis shall be given to the special medication factors, such as the combination with western medicines and Chinese herbal decoctions, overdose and long-course medication and self-medical therapy. In conclusion, the general ADR/ADE prevention regularity for Chinese patent orthopedic medicines was summarized to provide supports for clinicians in safe and rational medication and give the guidance for pharmacist in medication education.

Review[Study of effective components and molecular mechanism for Guizhi Fuling formula treatment of dysmenorrhea, pelvic inflammatory disease and uterine fibroids].
In this study, the active components and potential molecular .mechanism of Guizhi Fuling formula in treatment on dysmenorrhea, pelvic inflammation, and hysteromyoma were investigated using network pharmacological methods. Sterols and pentacyclic triterpenes, with high moleculal network degree, revealed promising effects on anti-inflammatory, analgesic, anti-tumor, and immune-regulation, according to D-T network analysis. ⋯ Thus, the main mechanism of Guizhi Fuling formula was summarized. In conclusion, Guizhi Fuling formula was proven to alleviated dysmenorrhea, pelvic inflammation, and hysteromyoma by acting on multiple targets through several bioactive compounds, regulating 21 biological pathways.
