Objective To observe the inhibitory effect of IL-4 on the IL-1?-induced rat mesangial cell proliferation, the release of PGE 2, and on the COX-2 mRNA and protein expression, so as to explore the related mechanism of anti-glomerulosclerosis. Methods Rat mesangial cell (MC) was cultured in vitro and the IL-1? -induced proliferation of MC was detected by MTT method. ELISA method was employed to measure the contents of PGE 2 in blank control group, IL-1? group, IL-4+IL-1? group, NS-398 group, NS-398+IL-1? group, indomethacin group, indomethacin+IL-1? group. The expression of mRNA and protein of COX-1 and COX-2 gene were detected by RT-PCR and Western blot, respectively. Results IL-1? could induce the proliferation of MC when the concentration was 0.1-100ng/ml in 12h, 24h and 48h. When its concentration was 2ng/ml, it had the strongest effect in 24h. All the IL-4, NS-398, indomethacin could inhibit IL-1? to induce MC producing PGE 2. The inhibitory rates are in proper order as: IL-4 (84.9%), NS-398(56.5%), and indomethacin(41.2%). Both IL-4 and NS-398 could obviously inhibit the expression of COX-2 mRNA and protein proved by RT-PCR and Western blot. Indomethacin could strongly inhibit the expression of COX-1 mRNA and protein, while only shew a weak inhibition on the expression of COX-2 mRNA and protein. Conclusion IL-4 could markedly inhibit the IL-1? -induced MC proliferation, down-regulate COX-2 gene, decrease the production of PGE 2, and thus take effect on anti-glomerulosclerosis.

BACKGROUND:Under physiological conditions, nerve roots can move along with the movement of limbs and spine. However, the mechanisms of nerve root stretch injury under physiological conditions and the neurological dysfunction after injury are unclear.
OBJECTIVE:To review the reason of nerve root stretch injury, and to analyze the mechanism of nerve function from biomechanics, pathology and neurophysiology.
METHODS:A computer-based online search of PubMed database was undertaken by the first author to identify the articles related to the research of nerve root injury and nerve stretch injury between 1990 and 2012, with the key words of“nerve root, nerve, stretch injury”. A total of 391 articles were screened out. The articles on the anatomy and biomechanics research of nerve root were included, as wel as the pathology and neurophysiology research after nerve root stretch injury. Final y, 44 articles were included for review.
RESULTS AND CONCLUSION:Nerve root can be stretched along with limbs and spine movement. However, diseases or trauma may cause pathological nerve root stretch, and thus leading neurological dysfunction. The nerve root is often influenced stretch because of its anatomical and tissue structure. Mechanical injury mechanism of stretch composes of peripheral (peripheral nerve conduction stress) and central mechanism (displacement of spinal cord content). Pathological studies found that the local fibrosis is caused by the extracted serum protein that difficult to remove after injury, and this is because of the shortage of lymphatic system in nerve roots. Fibrosis can cause nerve root ischemia, affect the nerve function, and change the biomechanical properties of nerve root. Nerve root injury can cause primary and secondary injury of internal axons, and this is the main reason for neurological dysfunction after injury.

Malignant neoplasm recurrence is the most important prognostic factor for patients.Looking for tar-get gene is an important part of cancer research.Annexin Ⅰ (ANXA1 )is to be discovered in the seventies century, composition by 13 calcium -phospholipid binding proteins annexin superfamily members of the first molecules. ANXA1 expressed in a variety of malignant tumors,ANXA1 expression levels were significantly reduced or absent in most tumor tissues.The study found that changed ANXA1 expression in tumor cells may have a causal relationship with the malignant phenotype of tumor cells.This paper aims to investigate the relationship between annexin Ⅰ and malignant neoplasm metastasis.

Objective:To investigate the changes of circulating tumor cells in locally advanced esophageal squamous cell carcinoma pa-tients treated with concurrent chemoradiotherapy. The effect of these alterations on the patients’prognosis was also analyzed. Meth-ods:Circulating tumor cells were detected by immunomagnetic enrichment and fluorescence in 48 cases of locally advanced esopha-geal carcinoma patients treated with concurrent chemoradiotherapy. The dynamic changes of circulating tumor cells were compared between pre-and post-chemoradiotherapy. Moreover, the association of these changes with the clinical characteristics and two-year survival rate were analyzed. Results:The positive rate of circulating tumor cells was closely associated with the T stage, lymph node metastasis, and clinical stage (P<0.05), and the positive rates in pre-and post-chemoradiotherapy were 52.1%(25/48) and 20.8%(10/48), respectively. The difference was statistically significant (P<0.05). Kaplan-Meier analysis showed that the positive rate of circulating tumor cells predicted an adverse two-year survival rate in both pre-and post-chemoradiotherapy (P<0.05). Cox regression analysis showed that the clinical stage and circulating tumor cells after concurrent chemoradiotherapy were independent prognostic factors in the patients with esophageal carcinoma. Conclusion:Circulating tumor cells can reflect the disease progression in patients with locally advanced esophageal cancer. These cells can also predict the prognosis of esophageal cancer patients treated with concurrent chemo-radiotherapy.
