Autoimmune disease is a condition arisen from an abnormal immune response to the tissue cells itself, its precise mechanism remains unknown, and the failure to distinguish self from non-self is often termed a breach of tolerance and is the basis for autoimmune illness. The tumor necrosis factor-α (TNF-α) induced protein 8 like-2 (TIPE2) is a newly discovered member of TNF-α induced protein 8 (TNFAIP8) family which is an essential negative controller of both innate and adaptive immunity. It has been documented that marked expressions of TIPE2 are evident in various autoimmune diseases, including autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), myasthenia gravis (MG) and systemic lupus erythematosus (SLE), which appear to be closely related to the severity, progression as well as prognosis of the illness, thereby contribute to the pathogenesis of autoimmune diseases. Deficient expression of TIPE2 might contribute to the hyper-reactivity of auto-reactive lymphocytes and macrophages, or aggregate inflammatory reaction by prompting high concentration of pro-inflammatory cytokines in peripheral blood, thus, trigger the development and progression of autoimmune diseases. In addition, dysregulation of immune homeostasis could be another latent target involved into the mechanism of autoimmune diseases. The present paper summarized the potential role and its mechanism of TIPE2 in the development of autoimmune diseases.

Objective To investigate the effect of Tetramethyl Pyrazine(TMP) for treating cerebral infarct by observing infarct areas,and to research its function mechanism by observing the changes of the expressions of ED1,TNF-? and IL-1? in the infarction region after focal cerebral ischemia reperfusion injury.Methods Sixty SD male rats in healthy condition were randomly and averagely divided into normal group,model group and TMP high,middle and low dose group.The cerebral infarct animal model was reproduced by modified thread-tie method.TMP high dose group was administered TMP 140 mg/kg,middle dose group was 120 mg/kg and low dose group was 100 mg/kg by intravenous.Then all the rats were killed.Thirty rats were taken to evaluate whether TMP can decrease the ratio of cerebral infarction areas in the TTC-reacting and formalin fixation brain tissue slices taken from the above-mentioned killed rats,with Pathology Image Analysis System.The masculine of ED1,IL-1? and TNF-? in the immuno-reacting cells in cerebral infarction brain tissue slice taken from other thirty killed rats were observed.Results TMP groups decreased the ratio of cerebral infarction areas,and also decreased ED1,TNF-? and IL-1? in immuno-reacting cell.Conclusion TMP can decrease the formation of cerebral infarction caused by cerebral ischemia reperfusion and its effect is possibly related to the activation of microglia,as well as the immuno-positive expressions of TNF-? and IL-1?.

Ultrasound molecular imaging has become one of the hotspots of molecular imaging because of its advantages of non-invasion, non-radiation, repeatability and real-time dynamic imaging. The key of imaging is to select the appropriate target and ligand to bind to the ultrasound contrast agent. The formation of blood vessels in the development of tumor is a significant feature. Vascular endothelial growth factor receptor (VEGFR) is an important specific molecule on tumor vascular endothelial cells, and which can be used as a target for tumor ultrasound imaging. In recent years, many scholars have carried out related studies on the imaging of ultrasound molecules targeting VEGFR. This paper reviewed the mechanism and application of tumor ultrasound molecular imaging with VEGFR as target in recent years.

Infectious diseases are resulted from the invasion of an organism's body tissues by multiple disease-causing agents. It has been demonstrated that the occurrence and development of infectious diseases are closely associated with the functional status of immune system. Cytokines play significant roles in modulating the host immune response to the clearance of pathogenic microorganisms and maintaining immune homeostasis. Interleukin-35 (IL-35), as a newly identified member of IL-12 family, exerts suppressive effect on immune response by means of a specific pattern. With the progress of research in recent years, IL-35 might serve as an essential contributor in the immunopathogensis of vast infectious diseases, including hepatitis B, sepsis, tuberculosis and parasite infection, which simultaneously appear to be closely related to the severity, progression as well as prognosis of the illness. Apparently, IL-35 is regarded as a potent and promising anti-inflammatory cytokine in clinical application; its potential value may shed light on the therapeutic strategies for infectious diseases. Herein, we mainly review the potential role and its mechanism of IL-35 in the pathogenesis of infectious diseases.

Objective To investigate the effect of 18F-fluoro-deoxy-2-glucose hybrid positron emission tomography images combined CT image(I8F-FDG PET-CT) on gross target volumes in non-small-cell lung cancer (NSCLC). Methods Forty six patients with pathological defined NSCLC were included in the study. All patients were divided into three groups according to image features; lymphatic metastasis group(18 cases) , ate-lectasis group( 16 cases) , solitary focus group(12 cases). The gross target volumes by CT and by PET-CT (GTVct and GTVPET_CT)were compared with volume differentials and coherence. We also compared the coherence among the three groups. Results The median GTVCT and median GTVPET-CT of atelectasis group was 160.813 cm3 and 108.838 cm3(t = 13.592,P<0.05). The median GTVCT and median GTVPET-CT of lymphatic metastasis group was 65.233 cm3 and 84. 367cm3 (t = 2. 768, P < 0.05 ). In the solitary focus group , median GTVCT was 21.7 cm3,and median GTVPET-CT was 19.6 cm3 (t =0. 684,P >0.05). There was statistic difference in coherence among the three groups (lymphatic metastasis group 0.561, atelectasis group 0. 698, solitary focus group 0.740). Conclusion There are varying degrees of difference between GTVCT and GTVPET-CT in both volume differentials and coherence . Compared to CT, PET-CT could improve the accuracy of radio-therapy. Patients with lymphatic metastasis would most likely benefit from it.
