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.

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 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 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 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

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.
