The lymphatic vessel is one of the earliest routes for systemic neoplastic metastasis. But reports on research of the lymphatic vessel have been few compared to the study for tumor vessels. In the past few years,along with advances in understanding about the construction features of the lymphatic system,work has been done to determine the anatomic fundamentals of lymphatic metastasis. Many new specifi c markers of the lymphatic endothelium had been reported, which is useful to differentiate lymphatic vessels from capillary vessels. The lymphatic vessels are usually found in the animal tumor models, human tumors and peritumoral tissues. Furthermore, the molecular mechanism of lymph-angiogenesis has been discovered, which provide effective targets for anti-lymphatic metastasis of malignant tumors, make optimization of individualized treatment strategy possible to restrain lymph-angiogenesis of malignant tumors and so it could benefi t in improving patients' prognosis and survival.

In this paper,we reported the results of 36 cases with lumbar disc prolapse through conservative treatment in order to observe the relationship between the effect of conservative treatment and the results of CT scan.We found that the effectiveness of treatment was related to the size and location of the disc protrusion as well as the course of disease.The results suggested that these factors should be considered fully during selecting the methods of conservative treatment or operation in lumbar disc prolapse.

Background and purpose:Conventional cytology is valuable in diagnosing the cancer cells in lymph nodes of patients with lung cancer. However , the diagnostic value of detecting lymph node and paracancer micrometastasis was limited. Our study was to investigate the mRNA expression level of lung specif ic X protein(LUNX) and cytokeratin 19(CK19) and its signifi cance in the carcinogenesis,metastasis and prognosis of NSCLC. Methods: Quantitative analysis with reverse transcriptase polymerase chain reaction(Real-Time RT-PCR) was used to detect the mRNA expression level of LUNX and CK19 in 20 tumor tissues and 42 regional lymph nodes from 20 patients with NSCLC, and 6 lymph nodes from 9 patients with pulmonary benign diseases as control. Meanwhile, all lymph nodes were also examined by conventional pathological method. Results:①the mRNA level of Lunxin in cancer Tissue was signifi cantly higher than that in the control group, but there was no association with Lymphatic Metastasis,Tumor Size and TNM grade.②the mRNA level of Lunx in the cancer Tissues was signif icantly higher than that in the control group, and was associated with Lymphatic Metastasis,Tumor Size and TNM grade.③the mRNA of CK19 in lymph nodes was almost the same as control, and not associated with tumor size,lymphatic metastasis and TNM grade.④the mRNA of LUNX in lymph nodes was almost the same as control, which has no acossiation with lymphatic metastasis,tumor size and TNM grade.⑤ mRNA of CK19 and LUNX was unrelated to age,sex and histological type .⑥there was signifi cant difference between using Real-Time RT-PCR methods and the routine pathological methods to detect lymph node metastasis in lung cancer. Conclusion:This result suggested that the detection of LUNX message RNA and CK19message RNA might be helpful to diagnose NSCLC micrometastasis in lymph nodes. LUNX was superior to CK19 both in sensitivity and specifi city. The establishment of this method may increase the positive rate of detecting metastatic regional lymph nodes in non small cell lung cancer.
