With the intensifying climate change and the strengthening ecosystem management, quantifying the past and predicting the future influence of these two factors on vegetation change patterns in China need to be analyzed urgently. By constructing a framework model to accurately identify fractional vegetation coverage (FVC) change patterns, we found that FVC in China from 1982 to 2018 mainly showed linear increase (29.5 %) or Gaussian decrease (27.

Objective: Traditional Chinese medicine (TCM) is an ancient form of personalized medicine and may improve morbidity and mortality in patients with esophageal cancer. This retrospective study aimed to evaluate the utility of TCM in the treatment of stage IV esophageal squamous cell carcinoma (SCC).

Methods: We collected the medical records of patients with stage IV SCC admitted to Henan Provincial Hospital of Traditional Chinese Medicine and Linzhou Hospital of Traditional Chinese Medicine between July 2017 and June 2020.

To analyze the academic characteristics and medication rules of traditional Chinese medical master Liu Zu-yi for treating insomnia. Totally 178 cases of insomnia treated by Professor Liu were collected,and the treatment data were input into traditional Chinese medicine inheritance support system( TCMISS) by using data mining methods,such as essential information,frequency statistics of symptoms,syndrome type statistics,extraction of syndrome elements,frequency statistics of drugs; and four properties and five tastes of drugs,distribution of meridians,regularity of prescriptions,new prescription analysis were mined. It was found that the most commonly used drugs( over 100 times) were Albiziae Cortex,Longgu,Polygoni Multiflori Caulis,Ostreae Concha,Ziziphi Spinosae Semen,Crataegi Fructus; the commonly used couplet medicines were Longgu-Ostreae Concha,Ziziphi Spinosae Semen-Polygoni Multiflori Caulis,Ziziphi Spinosae Semen-Albiziae Cortex-Polygoni Multiflori Caulis; and seven new prescriptions in treating insomnia were explored,such as prescriptions containing Hordei Fructus Germinatus,Ziziphi Spinosae Semen,Galli Gigerii Endothelium Corneum,Rehmanniae Radix,Lilii Bulbus.

On account of high oxidation ability of sulfate radical-based advanced oxidation processes (AOPs), the eco-friendly catalysts for peroxymonosulfate (PMS) activation have received considerable attentions. Previous studies mainly focused on Cobalt-based catalyst due to its high activation efficiency, such as CoO/MnO and FeCo-layered double hydroxide (LDH), whereas Cobalt-based catalyst usually has serious risk to environment. To avoid this risk, MnFe-LDH was primarily synthesized in this research by simple co-precipitation and subsequently utilized as an effective catalyst for peroxymonosulfate (PMS) activation to degrade organic pollutants.

Persulfate (PS)-based advanced oxidation processes have aroused considerable attentions due to their higher efficiency and wider adaptability to the degradation of bio-recalcitrant organic contaminants. In this study, Cu-Fe layered doubled hydroxide (CuFe-LDH) was employed to degrade Methyl Violet (MV) through heterogeneous photo-activation of PS under visible-light irradiation. The reaction kinetics, degradation mechanism, catalyst stability were investigated in detail.

Context: Radix Bupleuri has been used in traditional Chinese medicine for over 2000 years with functions of relieving exterior syndrome, clearing heat, regulating liver-qi, and lifting yang-qi. More natural active compounds, especially saikosaponins, have been isolated from Radix Bupleuri, which possess various valuable pharmacological activities.

Objective: To summarize the current knowledge on pharmacological activities, mechanisms and applications of extracts and saikosaponins isolated from Radix Bupleuri, and obtain new insights for further research and development of Radix Bupleuri.
