S-phase kinase associated protein (Skp2) assumes the high expression in the most of malignant tumors, with its occurrence, and the development and the prognosis is closely related with a latent diagnose and treat went value. This review will focus on unique feature, biology activity, the function mechanism and with malignant tumor relations of the Skp2.

Using Campylobacter ieiuni, strain of CJ-S131 to infect KM mice. Three months after infection, we examined the function of T and B cells in infected mice. We found that(l) there were higher, level antibodies against ds-DNA, ss-DNA.(2) ConAinduced suppressor cell activity was decreased and the ratio of Th/Ts was increased (3) The formation of PFC and lymphocyte transformation induced by LPS.PHA and ConA were increased. (4) The DTH reaction also was increased. The results mentioned above indicated that chronic infection of CJ-S131 would induce autoimmunity in KM mice.The ineffitiency of Ts cell function could be related to the hyperactivity of Th and B cells.

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 analyze the cause of prosthesis loosening by observing the interface membranes harvested during the hip restoration operation. Methods: A total of 28 specimens of interface membrane around the loose prosthesis were harvested from 28 patients undergoing the restoration of total hip replacement. All the specimens underwent the observation of appearance, light microscopy and scanning electronic microscopy(SEM). Results: All the gaps around the loose prosthesis were filled with interface membrane of different thickness. The color of the most interface membrane was madder red, and the other one third of membrane was black. The comparatively thicker membrane was similar to scar connective tissue while the thinner was similar to fiber membrane. A large number of wear debris, macrophages and foreign-body giant cells were found under light microscope. With SEM observation a large number of different diameter collagen fibra structures that looked like scar tissues were arranged disorderly in a great mass, foreign particles and bone debris of different size were distributed unevenly, and the fibroblast was distributed in the collagen fiber. Conclusion: Wear debris is related to inflammatory cell response around the interface membrane of the loose prosthesis. The wear debris engulfed by macrophage stimulates the interface membrane to release bone resorption factors (such as TNF) which lead to osteolysis, and this is one of the most important causes of the prosthesis loosening.

Fracture healing has long been a major concern for orthopedists.Currently,about 10% of fracture patients still have poor fracture healing or bone nonunion.In recent years,research has found that nerve growth factor(NGF)can promote fracture healing.This article reviews the mechanism and research progress of NGF in promoting fracture healing.NGF can promote vascular regeneration and nerve growth at callus and plays an important role in the proliferation and migration of bone cells.New animal experiments and clinical trials have confirmed the role of NGF in promoting fracture healing and further revealed its possible mechanism of action.Further research on NGF can provide new ideas for promoting fracture healing,especially for treating nonunion.

Lung cancer is the main cause of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) accounts for about 80% of lung cancer cases, but only 25%-30% of initially diagnosed patients have the option of radical surgery because of the lack of effective measures for early diagnosis. For locally advanced and advanced NSCLC, radiotherapy alone or comprehensive treatment with chemoradiotherapy is the main treatment method; however, the curative effect is unsatisfactory. Recently, increasing evidence sug-gests that targeted drugs, such as epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), combined with radiotherapy/chemoradiotherapy represent a promising treatment modality for NSCLC. This review will discuss the research status of EGFR-TKIs and radiotherapy for locally advanced and advanced NSCLC.

Objective:To study the effect of Slit-Robo signal on the proliferation of human oral squamous cell carcinoma line Tb. Methods:The expression of Slit and Robo protein was measured with Western blot. After the addition of the monoclonal antibodies (mAb) of R5 against Robo1 receptor extracellular domain, the changes of cell proliferation were studied by MTT assay and clone formation assay,the expression of PCNA was measured with immunohistochemical staining. Results:Western blot showed that Slit and Robo proteins were expressed in Tb cells. The proliferation rate of Tb cells decreased and the expression of PCNA decreased after the addition of R5 mAb. Conclusion:Slit-Robo signal may regulate the proliferation of Tb cells by up-regulation of PCNA.

Objective To investigate the clinical efficacy of superficial needling plus external washing with Chinese herbal medicine in treating post-stroke shoulder-hand syndrome.Methods Sixty patients with post-stroke shoulder-hand syndrome were randomly allocated to treatment and control groups, 30 cases each. The treatment group received superficial needling plus external washing with Chinese herbal medicine and the control group, conventional acupuncture. Pain severity was assessed using the visual analogue scale (VAS) and upper limb function was assessed using the Fugl-Meyer Assessment (FMA) of motor recovery in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 96.7% in the treatment group and 83.3% in the control group; there was a statistically significant difference between the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the VAS score and the FMA score in the two groups (P<0.05). There were statistically significant post-treatment differences in the VAS score and the FMA score between the treatment and control groups (P<0.05).Conclusion Superficial needling plus external washing with Chinese herbal medicine is an effective way to treat post-stroke shoulder-hand syndrome.
