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.

With the development of natural products, the research activities on the solubilization methods of water-insoluble natural products have been carried out worldwide. Big molecular weight and poor solubility of most natural active ingredients lead to a very poor oral absorption and low bioavailability, which has extremely limited their development in pharmaceutical fields and clinical application. As a result, it is necessary to find out a suitable technique to improve the solubility and enhance the oral bioavailability of insoluble natural drugs. Based on the related references published in these years, this review introduced some new techniques to improve the solubility and bioavailability of natural drugs, including prodrugs, inclusion complex, solid dispersion, cocrystals, osmotic pump, liquisolid compacts, micronization, self-microemulsifying, nanosuspensions, lipsomes, polymeric micelles and so on, and summarized the theory, characteristics, application range, application examples, problems and development direction of each technique.

Objective To evaluate the clinical value of elasticity imaging and area ratio by ultrasonography in differential diagnosis of benign and malignant thyroid nodules.Methods Gray-scale ultrasound and elasticity imaging was used to examine 88 patients with thyroid nodules.The elasticity classification and area ratio were retrospectively reviewed and compared with pathology.The elasticity grades 1 - 3 predicted benign,grades 4 - 5 predicted malignant.Results Eighty-eight patients with 116 thyroid nodules were detected,93 nodules were benign and 23 nodules were malignant.( 1 )An elasticity grades of 1 - 3 was observed in 82 (95.3％) of 86 benign nodules,while elasticity grades of 4 - 5 in 19 (63.3％) of 30 malignant nodules.The diagnosis sensitivity,specificity and accurate rate of the elasticity grades was 82.6％,88.2％,87.1％.(2) The mean of elasticity imaging and area ratio of 93 benign nodules (1.31 ± 0.13 ) was statistically lower than that in 23 malignant nodules ( 1.73 ± 0.13 ) (t =13.536,P =0.001 ).( 3 )According to ROC analysis,the cut-off point of elasticity imaging and area ratio was determined as 1.52.With elasticity imaging and area ratio ＜ 1.52,89 nodules [98.9％(89/90)] were confirmed as benign and 22 nodules [84.6％ (22/26)] were confirmed as malignant by pathology.The diagnosis sensitivity,specificity and accurate rate of elasticity imaging and area ratio was 95.7％,95.7％,95.7％.(4)The area under the ROC curve of elasticity imaging and area ratio ≥ 1.52 was 0.996,significantly higher than that of elasticity grades ≥ 4 (0.891).The diagnostic accurate rate of elasticity imaging and area ratio was significantly higher than that of elasticity grades(95.7％ vs.87.1％,x2 =5.472,P=0.019).Conclusions The elasticity imaging and area ratio by ultrasonography can be used in the differential diagnosis of thyroid lesions.It is a new diagnostic indicator for diagnosis of thyroid lesions.
