Objective: Long non-coding RNAs (lncRNAs) recently have been identified as influential indicators in a variety of malignancies. The aim of the present study was to identify a functional lncRNA LINC00488 and its effects on thyroid cancer in the view of cell proliferation and apoptosis.

Methods: In order to evaluate the effects of LINC00488 on the cellular process of thyroid cancer, we performed a series of in vitro experiments, including cell counting kit-8 (CCK-8) assay, EdU (5-ethynyl-2'-deoxyuridine) assay, flow cytometry, transwell chamber assay, Western blot and RT-qPCR.

Objective: To improve germination rate and research the seed germination character of Rhodiola sachalinensis.

Methods: Made seed germinated under water or with moisture, at light or dark condition, effects of 6 different light qualities (black, white, blue, green, red and far red light) illumination on seed germination were studied. The seedling growth at different temperature were studied as well.

Objective: To research the molluscicidal effect, active components, thermal stability and light stability of endophyte LL3026 (Colletotrichum sp.) from Buddleia lindleyana

Methods: The molluscicidal effect of LL3026 against Oncomelania hupensis was determined as referring to the WHO guidelines for laboratory molluscicidal test, and the control experiments were performed with 1 mg/L niclosamide or dechlorinated tap water. The active components from LL3026 were extracted by different polar solvents.

Objective: To evaluate the image registration accuracy and efficiency of CT and MRI fusion using three algorithms in nasopharyngeal carcinoma (NPC).

Methods And Materials: Twelve sets of CT and MRI scans of 12 NPC patients were fused using three image registration algorithms, respectively: Mark-and-link, Interactive, and Normalized Mutual Information (NMI). Registration accuracy was evaluated by performing statistical analysis of the coordinate differences between CT and MR anatomical landmarks along the x-, y- and z-axes.

Purpose: To explore the pattern of metastasis to level II nodes and its relationship with tumor range in nasopharyngeal carcinoma (NPC) patients by using magnetic resonance imaging.

Methods And Materials: Magnetic resonance images of 618 NPC patients were reviewed. Nodes were classified as metastatic based on size criteria, the presence of nodal necrosis, and extracapsular spread.

Objective: To observe the molluscicidal activity and the fish acute toxicity of the molluscicides extracted from Ginkgo biloba sarcotesta by benzinum (EGSB) (with major component of ginkgolic acid), arecoline (ARE) and their combination.

Methods: Oncomelania hupensis snails were immersed in different concentrations of dry powder sarcotesta of Ginkgo biloba (DPGB), extract of Ginkgo biloba sarcotesta by water (EGSW) and EGSB by WHO recommended method for molluscicide screening to observe the molluscicidal activity, and also the inhibiting effect on the snails' climbing-up as well as acute toxicity to Brachydanio rerio. Niclosamide was used as control.
