Tumor is a complex systemic disease, involving abnormalities at multiple levels, such as DNA, RNA, protein and metabolite. According to the central rule, the derived omics methods are genomics, transcriptomics, proteomics and metabonomics. In the past few decades, there have been remarkable achievements in the single omics study of tumor, but the exact mechanism of tumor development is still unclear. In order to reveal the process of tumorigenesis and development in a more systematic way, the research of multiomics came into being, which promoted the transformation of tumor research paradigm from single parameter model to multi parameter system model. The integration of multi-omics methods is expected to clarify the mechanism of tumor occurrence and development, find biomarkers with diagnostic, prognostic and predictive performance, explore new treatment targets, and finally achieve predictive, preventive, and personalized medicine (PPPM). This paper reviews the research methods and progress of different omics techniques in tumor research, especially emphasizes the importance and scientific value of the integration of multiple omics techniques in tumor research and clinical related results.

AIM:To explore the diagnosis and treatment methods of radioaction-induced optic neuritis ( RION) through the clinical dates of 17 patients.
METHODS: It was a retrospective case series study. From August 2008 to October 2013, 17 cases (24 eyes) of Rion clinical dates from Chinese PLA General Hospital were studied. The diagnosis methods including visual acuity, pupil, fundus, visual field, fundus fluorescein angiography (FFA), visual electrophysiological testing, and head MRI. To analysis the clinical date of patients with diagnosis of RION by statistical description.
RESULTS: The deterioration degree of vision: 13 eyes were classified as Ⅳ, 9 eyes as Ⅲ, 2 eyes as II. Ten eyes RAPD ( + ) , visual electrophysiology is extinguished. The retina of 5 eyes showed flame hemorrhages and cotton wool spots exudation. Optic nerve head edema in one eye. T1 - weighted MRI enhanced in 19 eyes which showed optic nerve of the intracranial and intratubal segments abnormal changed, optic chiasm and pituitary stalk signal abnormalities and enhancement of the optic nerve. Tortuous optic nerves and rough edges were observed in 5 eyes. Treatment effect: 4 eyes of visual acuity improved, 1 eye from blindness to light perception,1 eye from 0. 08 to 0. 2, 1 eye from 0. 4 to 0. 6,1 eye from 0. 04 to 0. 15, the rest of the cases did not see any improvement.
CONCLUSION: The unique clinical manifestation of RION can provide objective basis for clinical diagnosis in time, but there have not been proven any effective treatments.

Migraine is one of the common and frequently encountered diseases. The study proves that 5-hydroxytryptamine (5-HT) receptor, plays an important role in the occurrence of migraine. Rat striatum was used for preparation of the cell membrane stationary phase (CMSP) in our experiments. The cell membrane chromatography (CMC)-offline-HPLC system was applied to specifically recognize the components from the drug pair of Chuanxiong Rhizoma and Angelicae Dahuricae Radix, which interact with the receptors on CMSP. The dissociation equilibrium constant (KD) was measured in a rat striatum/CMC system, performed by continuously pumping sumatriptan, a 5-HT1D agonist, ranging from 2.42 x 10(-8) to 4.84 x 10(-7) mol · L(-1) through a CMC column, and the capacity factors (k') were recorded. The KD value obtained from the model was (4.59 ± 0.33) x 10(-6) mol · L(-1) for imperatorin, and the rat model of migraine induced by nitroglycerin was applied to validate the pharmacological effects of the drug pair. The results indicated that the CMC method could be a quick and efficient way for characterizing the drug-receptor interactions in vitro.
