0.05).Conclusion There are no significant effects on bone metabolism and growth of children with small dose of IGs per day for a longer time.

It is difficult to perform a primary anastomosis when a pathological trachea is over-lengnthing resected. Thus the tracheal prosthesis is required to apply in the airway reconstruction. Severe defects in the early tracheal prosthesis result in failure of surgery. Great progress has been achieved in recent years as new materials and tissue-engineering techniques are applied. These efforts bring a bright future to clinical applications of tracheal prostheses.

OBJECTIVETo evaluate the value of FOXP1 and Cyclin E gene in primary central nervous system lymphoma(PCNSL) of immunocompetent patients on prognostic significance.

METHODSClinical data of 71 patients with newly diagnosed PCNSL from 2002 to 2007 was analyzed retrospectively. Immunohistochemistry method (HRP-EnVision(TM)) was performed to observe the expression of FOXP1 and Cyclin E gene in tumor tissue samples. The survival was analyzed by Kaplan-Meier survival curve, survival factors analysis by the Log-rank test and COX proportional hazards regression model.

RESULTSFOXP1 positive was observed in 35 of 51 patients (68.63%) and Cyclin E staining was present in 29 of 50 cases (58.00%). FOXP1(+) patients had a shorter overall survival (OS) than FOXP1(-) ones. 2-year OS rate in FOXP1(+) and FOXP1(-) patients were 23.33% and 73.56%, respectively(P = 0.0015). Cyclin E(+) patients had a shorter overall survival(OS) than cyclinE(-) ones. 2-year OS rate in Cyclin E(+) and Cyclin E(-) patients were 17.56% and 69.76%, respectively (P = 0.0017). Multivariate analysis showed that Cyclin E expression was an independent prognostic factor for shorter OS (P = 0.048). FOXP1 expression might be an important prognostic factor for shorter OS (P = 0.065).

CONCLUSIONCyclin E expression is an independent prognostic factor and FOXP1 expression is a possible prognostic factor for poor clinical outcome in patients with PCNSL.

OBJECTIVETo evaluate the efficacy and progression-free survival of erlotinib after progression of disease to gefitinib in patients with advanced pulmonary adenocarcinoma who previously obtained a disease control with gefitinib.

METHODIn this retrospective study, 12 patients with advanced or metastatic pulmonary adenocarcinoma,who were previously obtained a partial response or a stable disease with gefitinib,were treated with erlotinib after gefitinib failure. Erlotinib efficiency, progression-free survival and overall survival were analyzed.

RESULTSNice (75%)achieved stable disease and three (25%) achieved progression disease with erlotinib treatment after gefitinib failure. No complete response or partial response was observed. The disease control rate was 75%. The median progression-free survival and overall survival of erlotinib were 180 days and 831 days.

CONCLUSIONErlotinib seems to be an optional treatment after gefitinib failure for advanced pulmonary adenocarcinoma patients,who previously responded to gefitinib.

AIMTo investigate the effects of hepatocyte growth factor gene transfected MSCs transplantation on cardiac function and fibrosis in rats heart failure model induced by adriamycin.

METHODSMSCs were isolated from SD rats by density gradient centrifugation, purified, and transfected with Ad-hHGF. ELISA were used to detect the protein expression of hHGF in these MSCs. Forty SD rats underwent intraperitoneal injection with adriamycin to induce heart failure model. 8 healthy rats served as control, 24 survival rats were randomly divided into 3 groups (n = 8): Rats in Ad-hHGF transfected MSCs group were injected with Ad-hHGF transfected MSCs 2 weeks after the establishment of the model, rats in MSC group injected with suspension of MSCs only, and model group was injected with cold culture fluid. Heart function was evaluated by a physiological recorder 4 weeks after cell transplantation. Myocardial cell morphology and interstitial collagen were studied by electron microscope and were stained by Sirus red. TGF-beta1 was detected by immunohistochemical method.

RESULTS(1) MSCs could be transfected efficiently by Ad-hHGF, manifested by a higher level of expression in vitro, persisting 14 days at least. (2) Four weeks after the cells transplantion, cardiac necrosis in MSC-hHGF rats was improved when compared with those in the MSCs (P < 0.05) and Model group (P < 0.01). The heart function of the MSC-hHGF rats was greatly improved with an significant increase in LVSP and + dp/dt(max), although LVEDP still highter than that of normal rats. (3) MSC-Ad-hHGF decreased Myocardial collagen content and the level of TGFbeta1 compaired with MSCs transplanted rats (P < 0.01).

CONCLUSIONTransplantation of HGF gene transfected MSCs improved heart function, decreased myocardial collagen and the level of TGFbeta1.

OBJECTIVETo explore the feasibility of using an intracavitary convex array probe for detecting the distal extracranial internal carotid artery (ICA) by transoral carotid ultrasonography (TOCU).

METHODSForty patients underwent examinations with bilateral ICA inspected with an intracavitary convex array probe by TOCU to observe the internal diameter, visible length, peak systolic velocity (PSV), end-diastolic velocity (EDV) and resistance index (RI).

RESULTSEight of the 40 patients were excluded from the observation for the presence of carotid plaques. The examination was terminated in two patients due to sensitive throat and severe pharyngeal reflex. The rest of the patients completed the examination of the internal diameter, visible length, PSV, EDV and RI, which showed no statistically significant differences among them (P>0.05).

CONCLUSIONUsing intracavitary convex array probe, the distal extracranial ICA disease can be diagnosed with higher accuracy.
