Thirteen new diterpenoids, sauspatulifols A-M (-), including four -cleistanthane-type diterpenoids (-), eight 15,16-di---cleistanthane-type diterpenoids (-), and one 17---pimarane-type diterpenoid () as well as one known diterpenoid, cleistanthol (), were isolated.

Tumor-derived exosomal circRNA_102481 contributes to EGFR-TKIs resistance via the miR-30a-5p/ROR1 axis in non-small cell lung cancer.

Exosomes are messengers for intercellular communication and signal transduction. Circular RNA (circRNA) abnormal expression and regulation are involved in the occurrence and development of a variety of tumors. In the present study, exosomes in the serum of five patients with non-small cell lung cancer (NSCLC) were isolated before and after EGFR-TKIs resistance, and the circRNA expression profile was screened using a circRNA microarray.

Isolation, purification and structural characterization of two pectin-type polysaccharides from Coreopsis tinctoria Nutt. and their proliferation activities on RAW264.7 cells.

Coreopsis tinctoria Nutt. (C.tinctoria) is an annual herb of the Compositae family with many health benefits, such as clearing heat, antioxidant and anticancer activity.

Isolation, purification, and structural characterization of polysaccharides from Atractylodis Macrocephalae Rhizoma and their immunostimulatory activity in RAW264.7 cells.

Three water-soluble polysaccharides (AMAP-1, AMAP-2 and AMAP-3) were isolated and purified from Atractylodis Macrocephalae Rhizoma by using the combination of ion-exchange chromatography and gel permeation chromatography. The structures of the polysaccharides were characterized by chemical derivatization, HPGC, GC-MS, FT-IR, and NMR techniques. Structural analyses show that the three polysaccharides are pectin-type macromolecules consisting of homogalacturonan (HG) and rhamnogalacturonan type I (RG-I) regions in different ratios.

Structural characterization and antiviral activity of two fucoidans from the brown algae Sargassum henslowianum.

Purified fucoidans SHAP-1 and SHAP-2 with apparent molecular weights of 6.55 × 10 and 5.89 × 10, respectively, were isolated from Sargassum henslowianum by ion-exchange and gel-filtration column chromatography.

Structural characterization of three polysaccharides from the roots of Codonopsis pilosula and their immunomodulatory effects on RAW264.7 macrophages.

Three polysaccharides were isolated from the roots of Codonopsis pilosula by ion-exchange and gel-filtration chromatography. They were named RCNP, RCAP-1, and RCAP-2, and had apparent molecular weights of 1.14 × 10, 5.

[Effects of irrigation regimes on the variation of soil water and salt and yield of mechanically harvested cotton in Southern Xinjiang, China].

The expansion of soil salinization area is a threat to cotton production in Southern Xinjiang. How to control soil salt accumulation by developing precise irrigation strategy is currently a hot topic for the film mulching drip-irrigated cotton field. With aims for soil quality improvement and high yield, we investigated the effects of irrigation regimes on soil water and salt distribution, yield and fiber quality in major cotton production area of Southern Xinjiang.

[Modeling evapotranspiration of greenhouse tomato under different water conditions based on the dual crop coefficient method].

An experiment was conducted to investigate soil evaporation (E), crop transpiration (T), evapotranspiration (ET) and the ratio of evaporation to evapotranspiration (E/ET) of drip-irrigated tomato, which was planted in a typical solar greenhouse in the North China, under different water conditions [irrigation amount was determined based on accumulated pan evaporation (E) of 20 cm pan evaporation, and two treatments were designed with full irrigation (0.9E) and deficit irrigation (0.5E)] at different growth stages in 2015 and 2016 at Xinxiang Comprehensive Experimental Station, Chinese Academy of Agricultural Sciences.

Ginsenoside Rd attenuates mitochondrial permeability transition and cytochrome C release in isolated spinal cord mitochondria: involvement of kinase-mediated pathways.

Ginsenoside Rd (Rd), one of the main active ingredients in Panax ginseng, has multifunctional activity via different mechanisms and neuroprotective effects that are exerted probably via its antioxidant or free radical scavenger action. However, the effects of Rd on spinal cord mitochondrial dysfunction and underlying mechanisms are still obscure. In this study, we sought to investigate the in vitro effects of Rd on mitochondrial integrity and redox balance in isolated spinal cord mitochondria.

Clinicopathologic significance of β-catenin and matrix metalloproteinase-2 expression in non-small cell lung cancer.

The purpose of this study was to analyze β-catenin and matrix metalloproteinase-2 (MMP-2) expression in non-small cell lung cancer (NSCLC) and to investigate the association between their expression and clinicopathologic characteristics of NSCLC patients. Immunohistochemistry was performed to examine β-catenin and MMP-2 protein expression in 39 resected NSCLC samples and 8 adjacent normal lung tissues. Statistical analysis with SPSS13.

[A comparative study of survival time of surgery combined with chemotherapy and non-surgical chemotherapy in SCLC].

Objective: To compare the survival time of surgery combine with chemotherapy with non-surgery chemotherapy in SCLC.

Methods: 37 SCLC post operation patients were received 4-6 cycles of chemotherapy of "etoposide + cisplatin or carboplatin". 37 SCLC patients were selected be control group, whose age, stage and site of tumor were similar to surgery combine with chemotherapy group, and received 6 cycles of chemotherapy of "etoposide + cisplatin or carboplatin".

[Relationship between quinone oxidoreductase1 gene ns-cSNP and genetic susceptibility of esophageal cancer].

Objective: To explore the relationship between quinone oxidoreductase1 (NQO1) gene nonsynonymous cSNP and the genetic susceptibility of esophageal cancer.

Methods: Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and Allele-Specific PCR (AS-PCR) were employed to assess the polymorphism of NQO1 genes both in 106 patients with esophageal cancer and control subjects matched by age, gender and origin.

Results: It was shown that no C/C genotype was found at 406 of NQO1.
