Objective: To explore the main chemical compounds in Xiaoer Qixing Cha Formulae (XQCF), and investigate its mechanisms for the treatment of infantile functional dyspepsia (IFD). Methods: The chemical components were identified by UPLC-QTOF/MS analytic technique. Targets of the compounds were screened from TCMSP and SWISS database, and disease targets were screened from OMIM and TTD online database. Candidate targets of compounds were mapped to the disease targets as predict therapeutic targets for XQCF. Several networks were constructed and analyzed by Cytoscape ver. 3.2.1. Meanwhile, prescription compatibility in XQCF was interpreted from the network perspective based on distribution of the number of targets. Furthermore, Gene Ontology (GO) enrichment analysis and KEGG pathway analysis were operated via Clue Go to illustrate complex relationships between the potential targets and pharmacological mechanisms. Results: A total of fifty-three compounds were recognized or tentatively characterized belonging to XQCF based on MS data and online chemical database. Sixty-three therapeutic targets were screened. AKT1, FOS, SLC6A4, COMT and 5-HT receptors were focused as therapeutic targets of XQCF. Pathways including carbohydrate digestion and absorption, serotonergic synapse, calcium signaling pathway and cAMP signaling pathway were predicted as significant regulatory pathways. The results indicated that the predicted targets and pathways related in brain-gut axis to a great extent, which could be potential pharmacological mechanism of XQCF for the treatment of IFD. Conclusions: The findings in this study provided the experimental and theoretical basis for further research for XQCF. Those also illustrated a reasonable method worth intensive study on pharmacodynamic mechanisms of TCM Formulae.

Diabetic nephropathy is one of the most serious complications of diabetes mellitus. In the early stage, edema and proteinuria are the main clinical manifestations. In the later stage, glomerulosclerosis and interstitial fibrosis will occur. And the prognosis is poor. Nowadays, traditional Chinese medicine has a remarkable curative effect in the treatment of diabetic nephropathy. There are more and more studies on the treatment of diabetic nephropathy with traditional Chinese medicine, but most of them focus on the syndromes of diabetic nephropathy, which are short of in-depth research and summary on the mechanism of Chinese herbal prescriptions. In this paper, the traditional Chinese medicine inheritance support system and network pharmacology BATMAN-TCM software were used to collect and analyze the relevant literature. It was found that the core compatibility of Shanzhuyu, Fuling and Shuyu in the treatment of diabetic nephropathy is closely related to the signal transduction pathway and target of diabetic nephropathy, and has a positive effect on the improvement of clinical symptoms such as proteinuria, glycometabolism disorder, edema, etc. This paper explores the core compatibility of Shanzhuyu, Fuling and Shuyu on diabetic nephropathy, in order to provide reference for clinical treatment.

Highlights
Diabetic nephropathy is one of the most serious complications of diabetes mellitus, which seriously affects the quality of life of patients for the poor prognosis. Nowadays, Traditional Chinese Medicine has a remarkable curative effect in the treatment of diabetic nephropathy, which has brought some enlightenment to our research ideas. Traditional Chinese Medicine Inheritance Assistant Platform System (TCM Inheritance Assistant Platform) is an organic combination of computer science and TCM. By intellectualized processing of disease prescription, the data of disease information, syndrome information and compatibility of TCM can be more intuitive, which make Chinese herbal medicine and drug pairs for treating diseases more specialized and precise. Network pharmacology is based on system biology to analyze multi-target networks of drugs, and can combine Drug targets with diseases, which make the treatment of diseases more targeted. This paper collects and summarizes the prescriptions of traditional Chinese medicine for diabetic nephropathy in the past 10 years from China Knowledge Net, and uses the system of traditional Chinese Medicine Inheritance assistant platform and BATMAN-TCM database of network pharmacology to analyze the medication rules and action signal pathways. We concluded that Shanzhuyu(Cornus officinalis Sieb. et Zucc), Fuling (Poria cocos (Schw.) Wolf) and Shuyu (Dioscorea opposite) have certain positive effects on the compatibility in the prevention and treatment of diabetic nephropathy and hope to provide new ideas for the research and clinical treatment of diabetic nephropathy with TCM.

Objective: To observe the neuroprotective mechanism of water extract of Fomitopsis Pinicola on MPP+ induced apoptosis of mesencephala dopaminergic cells in vitro. Methods: The antioxidant activity of fungi was determined by FRAP method. The anti-inflammatory activity of the fungi was detected by LPS-induced NO release method. Mesencephalic dopaminergic neurons were labeled by TH staining to observe the survival of THir neurons. Results: In the anti-oxidant activity assay, the Trolox equivalent anti-oxidant capacity (TEAC) of water extract of Fomitopsis Pinicola was determined to be (165.80±7.13)μmol Trolox/g extract. Water extracts of Fomitopsis Pinicola treatment(100,50,25,12.5μg/ml) decreased NO formation significantly. MPP+ induced significant chromatin condensation in the nuclei of mesencephala dopaminergic neurons with nuclear lysis,the mitochondrial membrane potential decreased remarkably, and ROS production increased significantly. Compared with the MPP+ control group, the morphological changes of cell nuclei after apoptosis was reversed by water extract of Fomitopsis Pinicola. Water extract of Fomitopsis Pinicola treatment(50,25,12.5μg/ml) dramatically increased relative mitochondrial membrane potential compared with MPP+ control respectively. Compared with the MPP+ control, water extract of Fomitopsis Pinicola treatment (50, 25μg/ml) significantly decreased relative ROS formation respectively. Conclusions:Water extract of Fomitopsis Pinicola showed significant neuroprotective effect on mesencephala dopaminergic cells induced by MPP+. The water extract of Fomitopsis Pinicola showed antioxidant and anti-inflammatory activities. The mechanism of neuroprotective effect of water extract of Fomitopsis Pinicola may be related to inhibitory on mitochondrial oxidative stress.

Highlights

Objective: Provide a rapid and simple method to identify Yunpian Lurong. Method: Terahertz spectroscopy was used to detect Yunpian Lurong. Result: Compared with the reference wave, the spectral amplitude of Yunpian Lurong decreases significantly. The frequency - domain spectra of Yunpian Lurong are different from conventional Lurong. Compared with the spectrum of free space, both of them have obvious absorption to THz wave, but the intensity and location of absorption are different, which provides a basis for the identification of Yunpian Lurong. The refractive index of the two samples is obviously different, which may be related to the different internal structure and composition content of the samples. The absorption coefficient of the two samples are different as well, when the frequency ranges from 0 to 2.4 THz, the absorption coefficients of the two kinds of Lurong samples have obvious difference, which makes it easy to distinguish the Yunpian Lurong. Conclusion: This study proves that terahertz spectroscopy can be used as an efficient and convenient method to identify Yunpian Lurong.

Highlights
Yunpian Lurong is one of the "four wonders of Qizhou". It is of great significance to develop the method for testing its commercial specifications. At present, many scholars have applied the fingerprint technology of traditional Chinese medicine to identify the LuRong, which is complex, time-consuming and costly for sample pretreatment is needed before testing. Therefore, it is necessary to establish a nondestructive and rapid detection and analysis method to identify Yunpin Lurong. In the experiment, under the constant and dry room temperature, we used the terahertz spectroscopy to detect Yunpin Lurong, analyzed and compared the differentiation of erahertz time domain spectroscopy, frequency domain spectroscopy, refractive index and absorption spectroscopy between Yunpin Lurong and the conventional Lurong. The results show that Yunpin Lurong can be quickly identified by terahertz spectroscopy without destroying its surface and internal structure or complicated pretreatment. As a new detection technology, it has the advantages of simple operation, short time-consuming, low cost and pollution-free and a positive meaning for the rapid detection of Yunpian Lurong, which is a nondestructive testing method for quality analysis or identification of Chinese medicinal herb with a promising prospect.

Objectives: Evaluating the quality of systematic reviews/meta-analysis of Wenxin granule in treating cardiac arrhythmia to provide evidence for clinical practice, and analyzing the problems in the research to identify potential research priorities for researchers. Method: The systematic reviews of Wenxin granule in treating cardiac arrhythmia were searched from 8 databases. The methodological quality and evidence quality were assessed by AMSTAR and GRADE respectively. Results: Nineteen eligible systematic reviews with 52,905 participants were included. The overall scores of AMSTAR ranged from 3 to 10 with a mean score of 6.5, the median score was 6. There were 9 (9/19, 47.37%) systematic reviews had the score of 7 or more. 6 of them with appropriate information were assessed the quality of evidence by GRADE. The results showed that the overall quality of evidence was limited (range from “very low” to “low”), no “moderate” or “high” quality of evidence existed. For the outcome reporting, no systematic reviews reported endpoints and limited evidence showed that there is causality between Wenxin granule and adverse effects/events. The outcome matrix showed that there are obvious heterogeneity and incompleteness for the outcome reporting in included systematic reviews, so that some included studies cannot be conducted meta-analysis. Meanwhile, there were studies excluded because of inappropriate outcome measures, such as outcome measures did not meet inclusion criteria, treatment time did not meet inclusion criteria, treatment time was unclear, incomplete data or the data cannot be extracted. Conclusions: Wenxin granule have limited efficacy and safety for treating arrhythmia. In the future, high quality of RCTs and systematic reviews should be conducted. Core outcome set for cardiac arrhythmia is needed to improve outcome reporting and decrease waste.

Highlights
1. This is the first overview of systematic reviews for Wenxin granule in treating cardiac arrhythmia, which summarized the efficacy and safety of Wenxin granule in treating cardiac arrhythmia and strictly assessed the quality of methodology and evidence.
2. Besides methodological quality and evidence quality assessment, this overview also analyzed some other problems, such as outcome reporting in systematic reviews and RCTs, so that researchers may identify potential research priorities from the results.
3. The outcome matrix of included reviews showed that there was heterogeneity in outcome reporting, and some clinical trials cannot be included in systematic reviews or cannot be conducted meta-analysis in systematic reviews because of inappropriate outcomes reporting. These problems reduce the value of clinical trials and systematic reviews. This research presents that core outcome set for cardiac arrhythmia is necessary to solve these problems.

As one of the most common types of heart failure, the diagnosis and treatment of Ischemic heart failure are the main focus of clinic. In recent years, the studies on biomarkers have provided supports for clinical diagnosis, prognosis evaluation and stratification. The clinical application of new drugs and the development of non-drug treatment methods have brought more choices conventional treatment. At the same time, under the guidance of Traditional Chinese Medicine syndrome differentiation theory, Traditional Chinese Medicine therapy also plays an increasingly important role and shows its broad prospects .

Highlights
As the most common type of heart failure, the morbidity of ischemic heart failure is increasing year by year. Although physicians attach great importance to the study of ischemic heart failure, the clinical treatment and diagnosis of ischemic heart failure are still relatively lack of systematicness and pertinence. In this article, we will outline some clinical studies on ischemic heart failure in recent years, including diagnosis and treatment. We will also introduce the progress and the unique prospect of Traditional Chinese Medicine in the treatment of this disease.
