Objective To investigate the effect and mechanism of EGFR in inducing vasculogenic mimicry (VM)formation.Methods Immunohistochemistry was used to detect the expression of EGFR protein and CD34-PAS double staining was used to detect the VM in gliomas paraffin blocks.The migration and VM formation of U87 cell in hypoxic and normoxic groups were detected by transwell and three-dimensional culture.Then we used Western blot to detect the expressions of EGFR,AKT and PI3K protein.Results The positive rate of EGFR expression in VM positive patients was 94.4%,which was significantly higher than that in VM negative patients (71.8%).In hypoxic group,the abilities of migration and VM formation were significantly higher those in normoxic group.The expressions of EGFR,AKT and PI3K were higher in hypoxic group.Conclusion VM formation can be induced by the activation of EGFR/AKT/PI3K signaling pathway.EGFR is very important for VM formation.

As a tumor suppressor, p53 is activated by numerous cellular and environmental signals, and plays a criticalrole in the cell cycle regulation, cell apoptosis and senenscence. The murine double minute (MDM)2 and double minute mu?rine 4 (MDMX) are two important regulators. MDMX is a p53 binding protein with strong sequence homology to MDM2, but lacks ubiquitin ligase activity, and which is unable to target p53 for proteasomal degradation. MDMX regulates p53 activity through its binding with p53 and its postranscriptional modification. MDMX in the closed and open structure binds to p53 to regulate its activity. As the main partner of MDMX, casein kinase 1 alpha (CK1α) disrupts the intramolecular binding in MD?MX in the cooperation to regulate p53 activity. The process of MDMX and CK1αin the regulation of p53 is multi-step and complicated. In this paper the mechanism of MDMX and CK1αin the regulation of p53 protein was reviewed.

Objective:To evaluate the sonographic characteristics of primary lymphoma of the thyroid gland and to analyze histo-pathologic findings and other imaging features to improve the diagnostic accuracy of this disease. Methods: We retrospectively re-viewed the records of 20 patients with histologically proven primary lymphoma of the thyroid gland. The clinical, pathologic, sono-graphic, CT, and MRI features were analyzed. Results:Histology revealed non-Hodgkin lymphoma in 20 patients. Ultrasound revealed lateral thyroid lobe disease in 12 cases and the presence of unilateral masses in 8 cases. The main features seen were diffusely enlarged thyroid gland. The lateral or unilateral thyroid lobe was with hypoechoic masses intermingled with echogenic structures. A total of 16 cases showed enlarged lymph nodes, 5 cases showed invasion of trachea, and 1 case involved the trachea and esophagus. Conclusion:Primary lymphoma of the thyroid gland usually presents with clinical and sonographic findings mimicking a carcinoma or benign tu-mor. If clinical features revealed rapidly enlarging neck masses and sonographic characteristics represented by malignant features of Hashimoto thyroiditis, then we should consider lymphoma. However, the final diagnosis depends on histopathology.

Although there is great technological disparity between the best foreign lithotripters and domestic ones, the clinical efficacy of the latter is quite good. In this article, the characteristics, developing status and clinical applications of domestic lithotripters are introduced.

OBJECTIVE:To prepare ambroxol hydrochloride orally disintegrating tablets and to evaluate its quality.METHODS:Mannitol was used as main adjuvant to prepare ambroxol hydrochloride orally disintegrating tablet,the UV spec-trometry was adopted to determine ambroxol content,the disintegration time,taste and dissolution rate were evaluated.RESULTS:The optimal formulation was composed of MCC 50g,mannitol 20g,L-HPC 10g,and NaHCO3 2g;The detected concentration of ambroxol was linear in the range of 0.005～0.030mg/ml(r=0.9 999),the average recovery was 100.50%and RSD=0.71;The prepared tablets disintegrated completely within 30s.CONCLUSION:The orally disintegrating tablets is quick to disintegrate and is as effective as market tablets.

Objective To explore the clinical manifestation and laboratory examination of chronic diarrhea in children with acquired immunodeficiency syndrome(AIDS) and analyze the reasons that causes the chronic diarrhea in children.Methods Clinical data of 7 patients (male 4 cases,famale 3 cases)with AIDS with manifestation of chronic diarrhea among the 17 cases were diagnosed as AIDS in Beijing children′s hospital from Jan.1999 to Dec.2006.The time of diarrhea,degree of dinrrhea,characteristic of stool,accompaniment symptom,laboratory examination were retrospectively analyzed.Results The average onset age was 6 years old(from 2-9 years old).The average time of diarrhea was 6 months(from 1-16 months).Four cases main complained with chronic diarrhea,3 cases came to the hospital because of fever,cough and wasting;6 cases with diarrhea,7 cases with malnutrition and anemia,5 cases accompanied hypokalemia and metabolic acidosis,6 cases had delay in growth and development,2 cases with abnormal stool routine exam,1 case with positive stool culture of fungi.All patients were with lower CD4,5 cases with lower CD4/CD8.Conclusions Chronic diarrhea is a common symptom in children with AIDS,and usually accompanied by obvious delay in growth and development,malnutrition and anemia,the reasons that causes the chronic diarrhea are consi-dered to be related with both the opportunistic infection and HIV infection.
