[Comparative study on HPLC fingerprints between crude and processed Ligustri Lucidi Fructus].
To establish high performance liquid chromatography(HPLC) fingerprints for crude and processed Ligustri Lucidi Fructus,and to evaluate their quality through the similarity calculation and chemical pattern recognition. The separation was performed with Syncronis C_(18) column(4.6 mm × 250 mm, 5 μm), with acetonitrile(A) and 0.1% phosphoric acid solution(B) as the mobile phase for gradient elution, and a detection wavelength of 280 nm. HPLC was used to detect 22 batches of crude and processed Ligustri Lucidi Fructus,and the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine(2012 Edition) was used to evaluate the similarity among 22 batches. ⋯ According to the results of PLS-DA,11 constituents including hydroxytyrosol, tyrosol, specnuezhenide and oleuropein were the main marker components leading to the difference. The established fingerprint method is stable and reliable, and can provide method basis for quality control of crude and processed Ligustri Lucidi Fructus. Chemical pattern recognition is proved to be helpful in comprehensive quality control and evaluation of Ligustri Lucidi Fructus before and after the process.

[Discovery and application of traditional Chinese medicine efficacy markers based on systematic traditional Chinese medicine].
The quality marker(Q-marker) of traditional Chinese medicine(TCM) is a new concept of TCM quality control proposed in recent years. It is a hot issue in the research of modern Chinese medicine. The TCM efficacy is a high-level summary of the TCM therapeutic effect under the guidance of TCM theory. ⋯ In this paper, the concept and method of Q-marker were introduced into the study of Chinese medicine efficacy. The research method for systematic TCM was used to systematically discuss the connotation of TCM efficacy markers, the principles of discovery and determination, common research ideas and techniques by taking the representative research results as an example. This study provides new ideas for the research and discovery of TCM efficacy markers.

[Study on precise mechanism of Chinese patent medicine from perspective of activating data].
Traditional Chinese medicine(TCM) syndrome differentiation and treatment has a characteristic and advantageous efficacy in the prevention and treatment of major diseases(no matter for new or sudden infectious diseases or major chronic diseases). At present, the clinical application by Western medicine disease's name, stage, classification and other indications limits the role of TCM syndrome differentiation and treatment, and makes TCM difficult to play its advantages. Therefore, the therapeutic value and social value attribute of Chinese patent medicine after being launched in the market cannot be effectively demonstrated, or even generalized as adjuvants. ⋯ Block data 4.0: activation data in the era of artificial intelligence puts forward the concept of activation data, which can be regarded as a theoretical hypothesis for big data, provides a new cognitive thinking and solution for increasingly prominent data paradox between bioinformation explosion and clinical big data, and is a bridge between cross-border data association and fusion. After deeply mining the dominant and recessive value of clinical data and histological data, we can make the pathogenesis of syndrome differentiation and treatment from dark knowledge to clear knowledge. Therefore, with Chinese patent medicine as the guide, the research on the efficacy and mechanism of precise positioning of traditional Chinese medicine after marketing is carried out, and the precise system of "syndrome, disease, function, pathological link and biological connotation" is constructed, which provides a powerful basis and support for increasing the scientific and technological content of varieties.

[Study on clinical characteristics of Danshen Chuanxiongqin Injection in treatment of cerebral infarction in real world].
In this study, the clinical characteristics and drug combination rules of Danshen Chuanxiongqin Injection in the treatment of patients with cerebral infarction were analyzed. The inpatient information of 2 857 patients of cerebral infarction treated with Danshen Chuanxiongqin Injection in HIS database of 20 grade Ⅲ class A hospitals in China was collected, and a model was established by description analysis and Apriori algorithm, in order to explore the clinical characteristics and drug combination rules of Danshen Chuan-xiongqin Injection in the treatment of cerebral infarction. The results showed that among patients of cerebral infarction treated with Danshen Chuanxiongqin Injection, 1 727 patients were older than 65 years old, accounting for 69.61%, and 1 610 were males, accounting for 63.59%. ⋯ The results showed that the patients of cerebral infarction treated with Danshen Chuanxiongqin Injection were mainly elderly males, and often complicated with hypertension, coronary heart disease, diabetes and other basic diseases. The clinical application of Danshen Chuanxiongqin Injection was principally in line with the guidelines. In the treatment of cerebral infarction, it was often combined with Western medicine anticoagulant thrombolysis, antiplatelet drugs, traditional Chinese medicine blood-activating and stasis-dissolving prescription and other drugs with similar pharmacological effects, with an auxiliary therapeutic effect on patients of cerebral infarction complicated with other diseases, and can provide guidance for clinical medication.

[Analysis of traditional Chinese medicine from patent information sharing platform of coronavirus disease 2019 (COVID-19)].
Coronavirus disease 2019(COVID-19) is a newly emerged and highly contagious respiratory disease. Traditional Chinese medicine(TCM) has both systematism theory knowledge and clinical practical value in the prevention and treatment of COVID-19. Therefore, it was particularly important to examine the effect of TCM in the prevention and treatment of COVID-19. ⋯ The patents for treatment of coronavirus mainly focused on the treatment of coronavirus, while the patents for symptomatic treatment mainly focuses on the improvement of respiratory symptoms, such as fever and cough. There were 14 highly frequently used TCMs, including Glycyrrhizae Radix et Rhizoma, Scutellariae Radix, Lonicerae Japonicae Flos, Forsythiae Fructus, Isatidis Radix, Astragali Radix, Menthae Haplocalycis Herba, Gypsum Fibrosum, Houttuyniae Herba, Isatidis Folium, Rhei Radix et Rhizoma, Gardeniae Fructus, Platycodonis Radix, Armeniacae Semen Amarum. The analyzed results of the TCM patents from the patent information sharing platform of COVID-19 were consistent with the Guideline of Diagnosis and Treatment of COVID-19(7th edition), and the combination of TCM in each cluster may also provide future directions for drug compatibility.
