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 investigate the myocardial protective effects ,mechanism and safety of recombinant human erythropoie-tin(rHuEPO) pretreatment in the patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) .Methods Thirty pa-tients with rheumatic heart disease undergoing valve replacement surgery were randomly divided into the observation group and the control group ,15 cases in each group .The observation group was given rHuEPO 300IU/kg by hypodermic injection on preoperative 2 d ,once daily for twice .The control group was given the same dose of normal saline .The blood routine was performed before sur-geryandonpostoperative7d.Thelevelsofcreatinekinaseisoenzyme(CK-MB)andtroponinT(cTnT)weredetectedbeforeopera-tion ,at 6 ,24 ,72 h after the aorta opening (T0 ,T6 ,T24 ,T72 ) .At the end of CPB ,myocardial biopsy was conducted for detecting the myocardial apoptosis index (AI) .The CPB time ,aortic cross clamp(ACC) time ,postoperative ICU stay ,blood transfusion and post-operative complications were recorded .Results The level of postoperative CK-MB and cTnT in the two groups were significantly increased after the aorta opening ,which at T6 was highest ,followed by a downward trend .The levels of CK-MB and cTnT at vari-ous time points in the observation group were significantly lower than those in the control group .The main effect of rHuEPO pre-treatment had statistical difference between the two groups (P= 0 .01) .Myocardial AI in the observation group was significantly lower than that in the control group ,the difference showing statistical significance (P<0 .01) .The observation group had no risk leading to obviously increase postoperative Hb ,Hct values and thromboembolism ,but the postoperative blood transfusion amount was reduced .Conclusion rHuEPO pretreatment has the protective effect on myocardium in the patients undergoing cardiac surgery under CPB ,which can reduce myocardial apoptosis and has safe reliability .

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.

Objective: To explore the recovery process and the influence factors of post-partum depression (PPD) .Methods:22 women with PPD and 34 women of non-PPD were investigated with the Edinburgh Postnatal Depression Scale (EPDS) and the Delivery Woman General Situation Questionnaire (DWGSQ) at 18 months and 30 months after childbirth.Results:The EPDS scores of PPD (11.27?3.49 at 18 months;10.91?4.59 at 30 months) were significantly higher than that of non-PPD (7.59?3.83 at 18months;7.47?4.09 at 30 months) (t 1=3.636, P 1
