[Biogeochemical Characteristics in Shengli Site of Lijiang River Under the High Resolution Monitoring].

This study was done to understand the diel variation and factors influencing the hydrochemistry of the Lijing River in different seasons. This is a typical medium river located at Guilin City in the Guangxi Zhuang Autonomous Region, SW China. The Shengli site was selected for this study.

[Impact of Human Activities on Water-Rock Interactions in Surface Water of Lijiang River].

The influence of human activities on karst surface water quality has received increasing attention. To explore the impact of human activities on water-rock interactions in karst surface water, water samples were collected from July to November in 2016 in the Lijiang River, which is dominated by human activities. The samples were analyzed for the hydrochemistryand the characteristics of δC.

[Dynamic Variations and Sources of Nitrate During Dry Season in the Lijiang River].

Dynamic variations and sources of nitrate during dry season in the Lijiang River were analyzed using the nitrate concentrations and N and O isotope techniques, from the samples obtained from 13 sections in the Lijiang River from September 28, 2016 to December 28, 2016. Results show that the nitrate concentrations range from 0.46 to 18.

[Sources of Organic Carbon in the Surface Water of Lijiang River].

This study selected a larger typical karst basin, that of Lijiang River, as the research subject and studied the sources of organic carbon in the Lijiang basin in July, August, and September in 2016 by an isotope tracer method, a correlational analysis method, and endmember mixture model, using a stable isotope of carbon and the organic carbon to nitrogen ratio. The results showed the following. ① The spatial distribution characteristics of DIC concentration were as follows: karst area> karst and non-karst mixed area> non-karst area.

Abnormal alterations of miR-1 and miR-214 are associated with clinicopathological features and prognosis of patients with PDAC.

Pancreatic ductal adenocarcinoma (PDAC) is a devastating malignant disease with a poor prognosis. PDAC is known to be difficult to diagnose at an early stage and to exhibit poor recurrence-free prognosis, but there is also a lack of effective treatment and limited knowledge of its biological characteristics. Therefore, there is an urgent requirement for an improved understanding of the cellular or molecular properties associated with PDAC, and to explore novel avenues for the diagnosis and treatment of this disease.

Transport of Corilagin, Gallic Acid, and Ellagic Acid from Fructus Phyllanthi Tannin Fraction in Caco-2 Cell Monolayers.

. To investigate the absorption property of the representative hydrolyzable tannin, namely corilagin, and its hydrolysates gallic acid (GA) and ellagic acid (EA) from the Fructus Phyllanthi tannin fraction (PTF) . .

Fructus phyllanthi tannin fraction induces apoptosis and inhibits migration and invasion of human lung squamous carcinoma cells in vitro via MAPK/MMP pathways.

Aim: Fructus phyllanthi tannin fraction (PTF) from the traditional Tibetan medicine Fructus phyllanthi has been found to inhibit lung and liver carcinoma in mice. In this study we investigated the anticancer mechanisms of PTF in human lung squamous carcinoma cells in vitro.

Methods: Human lung squamous carcinoma cell line (NCI-H1703), human large-cell lung cancer cell line (NCI-H460), human lung adenocarcinoma cell line (A549) and human fibrosarcoma cell line (HT1080) were tested.

[HPLC-fingerprint-based quality evaluation on a Tibetan medicine Phyllanthus emblica and its tannin parts].

This study is to establish the fingerprint for Phyllanthus emblica and their tannin parts from different habitats by HPLC for its quality control. The determination was carried out on a Diamonsil C18 (4.6 mm x 250 mm, 5 microm) column, with methanol-0.
