RESUMO
The efficacy of traditional Chinese medicine （TCM） and compound prescriptions is confirmed based on practical experience. It is a highly generalized expression of the clinical characteristics and scope of prescriptions and a unique expression of the medical effects of TCM. Network pharmacology， as a cross-disciplinary field based on the theory of systems biology and multi-level analysis of biological systems， has become a common virtual screening tool in TCM research and gradually developed with the progress in big data and artificial intelligence. In the context of modern medicine， the efficacy of TCM compound prescriptions has a vague concept and lacks scientific evidence. Elucidating the connotation of TCM efficacy and guiding TCM theoretical research has become one of the hotspots and difficulties in TCM research. This article explores the feasibility of using network pharmacology for the research on the efficacy of TCM compound prescriptions and investigates whether the research results can represent part of the efficacy of prescriptions. Furthermore， the research platforms and algorithms in this field are summarized. The research ideas and existing problems in this field are proposed from the aspects of efficacy concept embodiment， target screening， result verification， efficacy network building， and homogenization avoiding of network pharmacology research results. Finally， the future development directions are prospected. This article is expected to provide a reference for exploring the modern biological basis of the efficacy of TCM and compound prescriptions and for the clinical application and theoretical research of TCM.
RESUMO
Ulcerative colitis （UC） is a chronic recurrent inflammatory bowel disease which primarily affects the colonic mucosa. The UC patients mainly present diarrhea， abdominal pain， tenesmus， and mucous bloody stools， and even malnutrition and systemic symptoms in severe cases， with rising incidence， which has a significant impact on the health and quality of life of patients. The pathogenesis of UC is not clear， and the Western medical therapies include sulfasalazine， glucocorticoids， and immunosuppressants， which， however， have side effects and unsatisfactory effects. Chinese medicine with high safety， mild adverse reactions， and a multi-component， multi-target， and multi-pathway treatment manner has garnering increasing attention. Therefore， finding the Chinese medicine to treat UC has become a hot spot. Glycyrrhizae Radix et Rhizoma is one of the commonly used Chinese herbal medicines， with the effects of tonifying spleen and reinforcing qi， clearing heat and detoxifying， dispelling phlegm and relieving cough， relieving pain， and harmonizing medicines. Glycyrrhizae Radix et Rhizoma mainly contains glycyrrhizic acid， glycyrrhetinic acid， diammonium glycyrrhizinate and other active ingredients. Modern pharmacological studies have shown that Glycyrrhizae Radix et Rhizoma has anti-inflammatory， antioxidant， antimicrobial， and immunomodulatory activities. According to statistics， Glycyrrhizae Radix et Rhizoma is among the top three Chinese herbal medicines for the treatment of UC. The recent years have witnessed progress in the treatment of UC with Glycyrrhizae Radix et Rhizoma and the related prescriptions. The present study summarized the mechanisms underlying the anti-inflammatory， immunomodulatory， intestinal flora-regulating， cell apoptosis-inducing， and oxidative stress-reducing effects of the key chemical constituents （glycyrrhetinic acid， diammonium glycyrrhizinate， polysaccharide， glycyrrhetinic acid， and isoglycyrrhizin） and compound prescriptions of Glycyrrhizae Radix et Rhizoma. The findings provide a solid foundation for further development and clinical application of Glycyrrhizae Radix et Rhizoma.
RESUMO
Traditional Chinese medicine（TCM） has the characteristics of multiple ingredients, multiple targets, and complex action pathways. Under the guidance of the holistic view and syndrome differentiation treatment, TCM and its compound have great advantages in the treatment of diseases, and its material basis and molecular mechanism of action is not clear, so there are great challenges in the research of TCM. Network pharmacology has become a new research method and technical means for the modernization of TCM. It is a research discipline derived from the study of the mechanism of TCM treatment of diseases with multi-component drugs and multiple targets under the guidance of system biology theory. It conforms to the systematic and holistic thinking mode of Chinese medicine. At present, there have been many researches on the application of Internet pharmacology in Chinese medicine, including the research on the basis and mechanism of the Chinese medicine single drug, drug pair and compound pharmacodynamics, the methods and applications of Internet pharmacology for Chinese medicine research application of combining pharmacology with other technologies. However, the rapid data update, the emergence of new databases, the types of algorithms and the use of tools have made the development of network pharmacology too fast. People have neglected to update the databases, tools and algorithms and compare the advantages of each database. This article summarizes and compares the database, tools and algorithms of the network pharmacology in the past three years, and describes the network through the substance basis of TCM, the pharmacological mechanism of TCM, the development of new drugs, the quality control of TCM, and the formulating rules of TCM. The application and problems of pharmacology in the field of TCM are expected to provide a reference for the research and application of network pharmacology in TCM.
RESUMO
The preparation of Calculus bovis and its compounding preparations have been used widely in clinical practice.Traditionally,the forms of medicine were in raw material medicine way,preparing tablet,pill,powder or directly taking its powder.The main active ingredient of Calculus bovi were considered to be bilirubin and bile acids.However,the traditional formulations caused low bioavailability and wasted expensive herbs because its main component were insoluble in water.In recent years,many researchers have tried to use modern preparation technology to prepare its compounding formulations,such as solid dispersion technology,ultrafine grinding technology,powder coating technology,liposome encapsulation technology,or simplifying the prescription by using of known pharmacological effects of soluble components as substitutes.These methods were considered to be feasible to develop new formulations of Calculus bovis.In this paper,in order to provide reference of method and technology for the improvement of Calculus bovis compounding preparation and the development of new dosage form,ultramicrostructure,chemical composition,improvement methods and techniques of compounding preparation were analyzed.In addition,the relevant techniques and method of improving the formulation Calculus bovis compounding preparation in recent years were reviewed.

RESUMO
Objective: To investigate into the etiological factor,distribution of syndrome(patterns),pathogenesis features as well as the curative effects of small compound prescriptions of(Traditional) Chinese Medicine(TCM) in the treatment of acute stroke in stroke unit.Methods:(Cases) corresponding to diagnosis standards were randomly divided into control group(102 cases) and treatment group(156 cases).Conventional treatment methods were given to cases in control group.On the base of control group,small compound prescriptions were added to in treatment group,successively 14-21 days.The relation between types and time and TCM scale(TCMS),the NIH stroke scale(NIHSS) and Barthel index(BI) were observed in the two groups.Results: Stroke was age-related,the older,the more stroke patients.Stroke was closely related to hypertension.Ascending hyperactivity of liver yang was main type in the previous three days,this type(decreased) with the time going on.On the contrary,the type of wind phlegm and blood stasis was secondly main type in the previous three days,it increased with the time going on.Types of ascending hyperactivity of liver yang,wind phlegm and blood stasis as well as phlegm heat and constipation covered 95 per cent of all patients in the previous 21days.In the two groups,the mean scale of TCM and NIH decreased,and BI increased after treatment,this statistical difference could also be seen between the two groups.Conclusion: Excessive types are main types in the acute stage of stroke.Types of ascending hyperactivity of liver yang,wind phlegm and blood stasis as well as phlegm heat and constipation are its main types.Transferring of ascending hyperactivity of liver yang into endogenous wind may be trigger of reaction link of wind,fire,phlegm and blood stasis in TCM theory.Small compound prescriptions of TCM aiming to clearing away liver fire to stop wind,to activate blood for removing blood stasis and phlegm,to removing phlegm and heat from discharge can reduce scale of TCM and NIH,increase BI in the treatment of patients in stroke unit,which provide beneficial proofs for evaluation of effects of TCM.
