ABSTRACT

Objective:To review and summarize the current research status of traditional Chinese medicine(TCM) for the treatment of chronic atrophic gastritis(CAG),provide references and hints for relevant studies,and contribute to the further understanding of TCM and the application of TCM in the treatment of CAG with scientific evidence. Method:The PubMed and Web of Science databases were searched for relevant literature on the treatment of CAG with TCM from their establishment to August 31,2020. Eligible randomized controlled trials (RCTs) and animal studies were included according to the inclusion and exclusion criteria,and then the information of the included studies was extracted,summarized,and organized for further analysis. Result:A total of 4 RCTs and 21 animal studies (including 13 papers on compound studies,3 papers on single herb studies,and 5 papers on monomer studies) about TCM treatment for CAG were included in this study. RCTs showed that TCM could work well in improving the pathological state of gastric mucosa and clinical symptoms in patients. However,there were problems of low study quality,and non-uniform diagnostic criteria for gastric mucosal pathology and clinical efficiency evaluation. Animal experiments mainly focused on the study of drug mechanism exploration,and their results showed that TCM treatment of CAG was characterized by multi-target action. However,the animal experiments also had some problems such as inconsistence of CAG animal model establishment,positive drug selection,drug intervention methods as well as intervention cycles among different experiments. Conclusion:The efficacy of TCM in the treatment of CAG has gradually gained global recognition,but there is still a need for further standardization and unification of research methods. In the future,high-quality clinical trials and standardized animal experiments are still needed to conduct in-depth studies on the time for intervention,intervention methods,active ingredients and mechanisms of TCM,so as to make contributions to the full understanding and application of TCM in the treatment of CAG.

ABSTRACT

Melasma, as a kind of melanosis, often occurs over the face of young and middle-aged women, which seriously affects the physical and mental health of patients. At present, it is believed that the occurrence of melasma is related to various factors such as ultraviolet radiation and changes in sex hormone levels in the body. However, the exact pathogenesis of melasma is still unclear and its clinical efficacy is not ideal. Therefore, it is of great clinical significance and social value to carry out basic researches on melasma diseases. Among them, the animal model of melasma acts as an important tool for studying melasma, and it is particularly important to clarify the pathophysiological mechanism of the occurrence and development of melasma. The common modeling methods include ultraviolet modeling, progesterone modeling and ultraviolet combined with progesterone modeling. However, there are still some problems in the practical application of animal models of melasma due to many influencing factors in the preparation of such animal models, and there is still a lack of a more complete and recognized model preparation scheme to this day, which reduces the success rate of model preparation and limits its application and popularization to some extent. In view of the key problems in the establishment and application of animal models of melasma, we comprehensively summarized the research status of the models from such aspects as experimental animals, modeling methods and model evaluation, and discussed the effects of different modeling methods and animal species, animal age and other factors on animal model of melasma by referring to and sorting out the recent literatures at home and abroad in recent years. This is to provide references for the preparation of more scientific, reasonable, economic and convenient animal models of melasma, lay a foundation for in-depth researches on the pathogenesis, prevention and treatment of melasma, and also provide reference for other animal model research.

ABSTRACT

Objective:To assess the anxiolytic effect of Chaimu Anshen granules (CMASG) and investigate its bioactive mechanism. Method:ICR mice were randomly divided into normal group, diazepam group(0.002 g·kg-1),Jieyu Anshen granules group(0.001 4 g·kg-1), high, medium, and low-dose (0.001 98,0.000 99,0.000 495 g·kg-1)Chaimu Anshen granule groups, with 20 mice in each group. To detect the anxiolytic effect of CMASG, mice were intragastrically administered for 4 weeks in the morning, and light-dark box transition test and open field test were performed once the other day. After the behavior tests, blood samples were collected. Six mice of each group were perfused with formalin through heart, and then the brains were fixed for immunohistochemistry test. Hippocampus of the other mice in each group were collected and stored in liquid nitrogen. The content of γ-aminobutyric acid(GABA)and glutamic acid(Glu)in hippocampus and blood samples were detected by enzyme-linked immunosorbent assay (ELISA), and the ratio of GABA/Glu was calculated. The expression of GABAα1 receptor was evaluated by the immunohistochemistry method. To test the hypnosis effect of CMASG, mice were administered intragastrically for 7 days. The sub-threshold dose of pentobarbital sodium in the sleep experiment was tested. Result:Compared with normal group, the light-dark box transitions test demonstrated that low-dose and medium-dose CMASG groups significantly prolonged the duration in light box(PPPPPPPPPPα1 receptor protein in hippocampus showed that the medium-dose CMASG significantly increased the expression of GABAα1 protein. The sub-threshold dose of pentobarbital sodium on sleep experiments confirmed that the medium-dose CMASG significantly increased the rate of sleep in mice. Conclusion:CMASG showed an anxiolytic effect, and its bioactive mechanism was related with the increase of GABA content, and the decrease of Glu content in hippocampus. Furthermore, it increased the expression of GABAα1 protein in hippocampus. The changes in content of GABA and Glu in peripheral blood were positively correlated with the changes in hippocampal tissues, which provided reference for clinical diagnosis. CMASG also exhibited an effect in improvement of sleep.

ABSTRACT

Objective:Define traditional Chinese medicine (TCM) therapeutic principles and methods and common prescriptions of benign prostatic hyperplasia (BPH) based on clinical experience of famous doctors. Method:China National Knowledge Infrastructure, China Biology Medicine disc, China Science and Technology Journal Database, Wanfang database were systematically retrieved for literatures of famous doctors in diagnosis and treatment of BPH from January 1, 1997 to December 31, 2018.A literature analysis database was established for integration and analysis of relevant content of TCM therapeutic principles and methods and prescriptions. SPSS 20.0 software was used for statistics to obtain TCM therapeutic principles and methods, common prescriptions and drug distribution regularity of BPH. Result:A total of 109 qualified literatures were included in this study, involving 66 famous doctors and experts, and 9 kinds of BPH therapeutic principles were obtained, including "treatment of both symptoms and root cause of disease", "tonification and purgation in combination", "coordination of Yin and Yang". There are 55 kinds of therapies, including "promoting blood circulation for removing blood stasis", "clearing heat and promoting dampness", "warming and recuperating kidney Yang", "softening and resolving hard mass" and " invigorating kidney Qi". And BPH was mostly diagnosed and treated based on kidney, spleen and lung. Through collection and summarization, totally 38 formulas commonly used in treating BPH obtained. The most commonly used ones were "Guizhi Fuling Wan", "Zishen Tongguan Wan", "Buzhong Yiqi Tang", " Bazheng Tang" and "Jisheng Shenqi Wan". There were 217 commonly used herbs, mainly including " Astragali Radix", "Rehmanniae Radix Praeparata", "Atractylodis Macrocephalae Rhizoma", "Glycyrrhizae Radix et Rhizoma", "Angelicae Sinensis Radix", "Radix Achyranthis Bidentatae", "Peach Kernel", "Pangolin Scales", "Vaccariae Semen", "Salviae Miltiorrhizae Radix et Rhizoma", "Poria", "Rhizoma Alismatis" and "Plantain Seed". Conclusion:The treatment of BPH is based on the principles of "treatment of both symptoms and root cause of disease, and tonification and purgation in combination". The commonly used therapies include prescription for "promoting blood circulation for removing blood stasis", "clearing heat and promoting dampness" and "warming and recuperating kidney Yang". The corresponding prescriptions shall be based on symptoms.
