[Study on screening potential traditional Chinese medicines against 2019-nCoV based on Mpro and PLP].
With the rapid outbreak of COVID-19, traditional Chinese medicine(TCM) has been playing an active role against the epidemic. However, the screening of TCM is limited by the development cycle and laboratory conditions, which greatly limits the screening speed. This study established optimization docking models and virtual screening to discovery potential active herbs for the prevention and treatment of the novel coronavirus based on molecular docking technology. ⋯ Rhei Radix et Rhizoma screened by Mpro and Trichosanthis Fructus screened by PLP were contained in Maxing Shigan Decoction and Xuanbai Chengqi Decoction, and could be applied to the syndromes of epidemic virus blocking lung. Mori Folium, Lonicerae Japonicae Flos and Forsythiae Fructus obtained by ACE2 inhibitors screening were included in the Sangju Decoction and Yinqiaosan, which might be applicable to the syndromes of warm pathogen attacking lung and cough and dyspnea. The results of this study are intended to provide a reference for the further development of traditional Chinese medicine to deal with the new epidemic.

[Quality evaluation of angelica broken wall powder based on QbD concept of traditional Chinese medicine].
In this paper, angelica broken wall powder(ABWP) was taken as the research object, HPLC fingerprint combined with multi-component determination(ferulic acid, senkyunolide I, coniferyl ferulate, ligustilide and 3-butylidenephthalide), physical fingerprint(D_(90), particle size distribution range, particle size distribution width, bulk density, tap density, inter-particle porosity, Carr index, specific surface area, pore volume, angle of repose, Hausner ratio, loss on drying and hygroscopicity)were used to characterize the quality attribute of ABWP; similarity analysis, cluster analysis, principal component analysis and orthogonal partial least squares discriminant analysis were conducted to construct the quality evaluation method of holographic analysis based on traditional Chinese medicine QbD "4 H mode", in order to evaluate the quality of ABWP from different sources and find out differentiated indicators. The quality evaluation method could be used for scientific, comprehensive evaluation of the quality attribute of ABWP, and the quality consistency evaluation of cell-wall-broken powder of different sources or different processes. It provides new ideas for quality control and research of ultrafine granular powders of traditional Chinese medicine.

[Construction and application of modern research paradigm of new foreign introducing traditional Chinese medicine].
With the development of society, more and more foreign natural medicines have entered China, but they are faced with the problem that they are not given with the traditional Chinese medicine(TCM) properties when they are used with other TCM. When we carried out the research on introducing foreign natural plant resources to TCM, gradually, a new research model and field with original characteristics of TCM--the study of new foreign introducing TCM had been formed. In the process of it, we explored and summarized research rules to form the research paradigm, which will be conducive to the standardization and scientization of new foreign introducing TCM research. ⋯ The paradigm was the practical application of theoretical innovation of TCM. Under the guidance of it, more and more varieties of new foreign introducing TCM will be studied, the study will be more standardized, the conclusions will be more scientific and reliable, which will inspire and guide more researchers to focus on the research of new foreign introducing TCM, and the paradigm itself will be constantly improved. The construction and application of the paradigm will certainly accelerate the innovative research of foreign introducing TCM and play a historic role in promoting the enrichment of traditional Chinese medicine varieties.

[Rapid establishment of traditional Chinese medicine prevention and treatment of 2019-nCoV based on clinical experience and molecular docking].
The coronavirus disease 2019(COVID-19) is raging in China and more than 20 other countries and regions since the middle of December 2019. Currently, there is no specific drug or vaccine besides symptomatic supportive therapy. Taking full advantage of the clinical experience of traditional Chinese medicine(TCM) in preventing and controlling major epidemics such as SARS, it is an important mission for TCM to propose effective formula with immediate response and solid evidence by using modern biomedical knowledge and techniques(molecular docking assisted TCM formulation for short). ⋯ The TCM prescription was combined with modern medicine symptomatic supportive treatment for clinical treatment, preliminary results showed better effect than symptomatic supportive therapy alone. This research has innovated the method mode in clinical practice and basic research integration of traditional Chinese medicine for the prevention and control of new emerging infectious diseases. It is of great significance to further improve the rapid response mechanism of TCM in face of major epidemics, and further improve the capability level of TCM to prevent and treat new emerging infectious diseases.

[Real-world study on syndrome distribution and medication characteristics of colonic malignant tumors].
In order to explore the characteristics of traditional Chinese medicine(TCM) syndromes and medications in patients with colonic malignant tumors in China, the clinical data of patients with colonic malignant tumors from the information system of 33 Grade-A tertiary hospitals in China from 2001 to 2016 were extracted and a descriptive analysis was conducted on their disease characteristics, syndrome distribution, drug characteristics and treatment status. A total of 22 691 patients with colonic malignancies nationwide were included in the analysis, with male to female ratio of 1.59∶1, median age of 62 years, susceptible age of 50-79 years. Postoperative patients with colonic malignant tumors accounted for 47.10%, and patients with liver metastases reached 36.02%. ⋯ The top three traditional Chinese medicines were compound Kushen Injection(14.62%), Shenqi Fuzheng Injection(10.18%) and Aidi Injection(6.48%). This study shows that spleen and Qi deficiency may be the dominant syndrome of colonic malignant tumor, and chemotherapy is one of the main treatment methods. Traditional Chinese medicine has shown unique advantages in alleviating the toxic and side effects of chemotherapy and preventing recurrence and metastasis, so integrated TCM and Western medicine can significantly improve the clinical efficacy.
