The leaves of sea buckthorn(Hippophae rhamnoides), considered as common food raw materials, have records of medicinal use and diverse pharmacological activities, showing a potential medicinal value. However, the active substances in the sea buckthorn leaves and their mechanisms of action remain unclear. In addition, due to the extensive source and large variety variations, the quality evaluation criteria of sea buckthorn leaves remain to be developed. To solve the problems, this study predicted the main active components, core targets, key pathways, and potential pharmacological effects of sea buckthorn leaves by network pharmacology and molecular docking. Furthermore, ultra-performance liquid chromatography with diode-array detection(UPLC-DAD) was employed to determine the content of active components and establish the chemical fingerprint, on the basis of which the quality markers of sea buckthorn leaves were predicted and then verified by the enzyme activity inhibition method. The results indicated that sea buckthorn leaves had potential therapeutic effects on a variety of digestive tract diseases, metabolic diseases, tumors, and autoimmune diseases, which were consistent with the ancient records and the results of modern pharmacological studies. The core targets of sea buckthorn leaves included PTPN11, AKT1, PIK3R1, ESR1, and SRC, which were mainly involved in the PI3K-AKT, MAPK, and HIF-1 signaling pathways. In conclusion, the active components of sea buckthorn leaves are associated with the rich flavonoids and tannins, among which quercitrin, narcissoside, and ellagic acid can be used as the quality markers of sea buckthorn leaves. The findings provide a reference for the quality control and further development and utilization of sea buckthorn leaves as medicinal materials.

Medicinal plants have provided numerous medicinal active ingredients for thousands of years and these ingredients have been used in Chinese medicine (CM) and traditional pharmacologies worldwide. Recently, the exploitation and utilisation of medicinal plant resources has increased significantly. The results of the studies have led to the identification of many active components, such as steroidal alkaloids, saponins, terpenoids, and glycosides, in various medicinal plants with different evolutionary levels. Moreover, research on the chemical classification, molecular phylogeny, and pharmacological activity of medicinal plants is increasing in popularity. Pharmacophylogeny is an interdisciplinary topic that studies the correlation between plant phylogeny, chemical composition, and curative effects (pharmacological activity and the traditional curative effect) of medicinal plants. In addition, it provides the basic tools to enable research and development of CM resources. This literature review, based on the genetic relationship between phytogroup and species, highlights the formation process, research content, applications, and future directions of pharmacophylogeny.

The aim of the study is to investigate the association of rs1975197 and rs4626664 of PTPRD and restless legs syndrome （RLS）.Methods We retrieved 4 studies on rs1975197 and 5 studies of rs4626664 and extracted basic information of each study following inclusion and exclusion criteria. Meta-analysis was used to analyze odds ratio（OR）and 95% confidence intervals（CI）.Forest plots were used to assess heterogeneity visually.If heterogeneity existed，subgroup analysis would be used. Funnel plots was used to assess publication bias visually.Results As for rs1975197，T allele could increase the risk of RLS in Caucasian（OR=1.43，95%CI 1.13～1.80）.However，there were no statistically significant of rs4626664 observed in neither overall analysis nor subgroup analysis.Conclusion T allele of rs1975197 of PTPRD increases the risk of RLS in Caucasian using Meta-Analysis，suggesting a race specificity of PTPRD with RLS. More and larger case-control studies including different races need to be launched for investigating the association of PTPRD with RLS.

The Solanaceae plants distributed in China belong to 105 species and 35 varietas of 24 genera. Some medicinal plants of Solanaceae are rich in tropane alkaloids(TAs), which have significant pharmacological activities. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, pharmacological activities, and biosynthetic pathways of TAs in Solanaceous plants were summarized. Besides, the phylogeny of medicinal plants belonging to Solanaceae was visualized by network diagram. Fourteen genera of Solanaceae plants in China contain TAs and have medical records. TAs mainly exist in Datura, Anisodus, Atropa, Physochlaina, and Hyoscyamus. The TAs-containing species were mainly concentrated in Southwest China, and the content of TAs was closely related to plant distribution area and altitude. The Solanaceae plants containing TAs mainly have antispasmodic, analgesic, antiasthmatic, and antitussive effects. Modern pharmacological studies have proved the central sedative, pupil dilating, glandular secretion-inhibiting, and anti-asthma activities of TAs. These pharmacological activities provide a reasonable explanation for the traditional therapeutic efficacy of tropane drugs. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, and modern pharmacological activities of TAs-containing species in Solanaceae were analyzed for the first time. Based on these data, the genetic relationship of TAs-containing Solanaceae species was preliminarily discussed, which provided a scientific basis for the basic research on TAs-containing solanaceous species and was of great significance for the development of natural medicinal plant resources containing TAs.

Objective:To observe the effect of Yiqi Yangyin prescription on lipid metabolism in type 2 diabetes rat model induced by high fat diet combined with intraperitoneal injection of streptozocin （STZ）， and explore its mechanism in regulation of lipid metabolism. Method:The rats were fed with high-fat diet for 4 weeks， and intraperitoneal injection of STZ was provided to establish diabetes model. The diabetic rats were randomly divided into model group， Yiqi Yangyin prescription high dose group， medium dose group and low dose group （9.00， 4.50， 2.25 g·kg^-1） and metformin group （0.20 g·kg^-1）. Another blank control group was set up. The high， medium and low dose groups were given with different oral doses of Yiqi Yangyin prescription granules， metformin was given in metformin group， the model group and the blank group received the same volume of normal saline. Intragastric administration was given for three weeks， and then the weight and blood glucose were measured. Automatic biochemical analyzer was used to detect triglyceride （TG）， total cholesterol （TC）， low density lipoprotein cholesterol （LDL-C）， high density lipoprotein cholesterol （HDL-C）， aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， and content of total protein （TP）. Hematoxylin-eosin （HE） staining was used to observe the pathological changes of liver tissues in each group. Periodic acid-schiff stain （PAS） staining was used to observe the pathological changes of liver glycogen. The lipid changes of liver tissues were observed by oil red O staining. The expression of adenosine monophosphate activated protein kinase （AMPK）/ sterol regulatory element binding protein 1c （SREBP1c）/acetyl-coenzyme A carboxylase （ACC1）/peroxisome proliferator activated re-ceptor α （PPARα） pathway in liver tissues was observed by Western blot. Result:Compared with the blank group， TG， CHO， LDL-C， AST， ALT and ALP significantly increased and HDL-C significantly decreased in the model group （P<0.05， P<0.01）. Compared with the model group， TG and LDL-C contents significantly decreased （P<0.05， P<0.01）and LDL-C contents significantly increased in Yiqi Yangyin prescription groups （P<0.05）. Histomorphology showed that Yiqi Yangyin prescription significantly reduced the degree of hepatocyte intercellular vacuoles and steatosis in liver， and significantly reduced the lipid area of liver tissue. Compared with the blank group， the protein expression levels of p-AMPKα， PPARα， SREBP-1 （plasma） in the liver tissues significantly decreased in the model group， but such expression levels increased after treatment with Yiqi Yangyin prescription （P<0.05， P<0.01）， compared with the blank group， the protein expression levels of p-ACC1 and SREBP-1 （nuclear） significantly increased （P<0.01） in model group， but such expression significantly decreased after treatment with Yiqi Yangyin prescription （P<0.05， P<0.01）. Conclusion:Yiqi Yangyin prescription can significantly reduce blood lipid in the diabetic rats caused by high-fat feed combined with STZ. The decrease of blood lipid in the type 2 diabetes rats may be related to the influence on AMPK/ACC1/SREBP-1/PPAR pathway in rat liver.
