Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions. The professional guideline is required to guide the standardized and efficient clinical comprehensive evaluation of Chinese patent medicine and further improve the authority and quality of evaluation. In combination with the characteristics of Chinese patent medicine and the latest research achievement at home and abroad,the detailed specifications were formulated from six aspects including design,theme selection,content and index,outcome,application and appraisal,and quality control. The guideline was developed based on the guideline development requirements of China Assoication of Chinese medicine. After several rounds of expert consensus and public consultation,the current version of the guideline has been developed.

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.

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.

OBJECTIVESTo evaluate the effectiveness and safety of Guipi Decoction (, GPD) as an adjunctive in the treatment of depression.

METHODSA review of all relevant studies retrieved from a search of the following databases were conducted without any language restriction: Excerpt Medica Database (EMBASE), PubMed, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure (CNKI), VIP Information, Wanfang Data, and the Chinese Biomedical Literature Database. Papers published until February 2013 were taken into consideration. The analysis was performed using the Cochrane software Revman 5.1.

RESULTSNine randomized controlled trials involving 620 patients with depression were included in this review. The meta-analysis revealed that compared with antidepressant therapy alone, treatment with a combination of GPD and an antidepressant drug signifificantly improved the symptoms of depression [weighted mean difference (WMD):-3.09; 95% confifidence interval (CI):-4.11 to-2.07] and increased the rates of effectiveness (OR: 4.75; 95% CI: 2.66-8.51) as well as recovery (OR: 1.73; 95% CI: 1.17-2.56). The adverse effects of GPD were not found to be signifificant in these studies.

CONCLUSIONSThe fifindings of this meta-analysis were in keeping with the notion that GPD formulations were effective in the treatment of depression without causing any serious adverse effects. However, currently available evidence was of low quality and therefore inadequate to justify a strong recommendation of using GPD formulations in the management of depression.

OBJECTIVETo observe effects of Fengbaisan (, FBS) on the expression of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in lung tissue of rats with chronic obstructive pulmonary disease (COPD) and to investigate the preventive and therapeutic mechanisms of FBS.

METHODSThe COPD rat model was established by cigarette smoke exposure and lipopolysaccharide (LPS) intra-tracheal dripping. The histopathological changes of lung tissue was observed via hematoxylin/eosin staining. The expression of MMP-9 and TIMP-1 in lung tissue was measured by reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry.

RESULTSThe typical histopathological changes of COPD were displayed in the model group, Ambroxol Hydrochloride group and FBS group, and the pathological lesions in the FBS group were less than those in the model group. The expression of MMP-9 and TIMP-1 in the model group increased significantly compared with those in the normal group (P<0.05). After treatment for successive 28 days, the expression of MMP-9 and TIMP-1 in the FBS group decreased remarkably as compared with the model group (P<0.05).

CONCLUSIONSFBS can regulate MMP-9/TIMP-1 imbalance to prevent airway and lung parenchyma remodeling process via reducing the expression of MMP-9 and TIMP-1 in the lung tissue of COPD rats, and this may be a possible therapeutic mechanism of FBS on COPD.
