With the development and clinical use of the molecular targeted drugs and individualized treatment,cancer research has been focused on gene targeting diagnosis and treatment.Especially for the epidermal growth factor receptor (EGFR) signaling pathway-related genes,DNA replication-related genes,spindle apparatus format-related genes,cell metabolism-related genes and other molecular targeted detection and treatment,the polymorphism of targeting genes/molecules determines the clinical efficiency of the therapies.

It has been shown that the PIK3CA mutation in HER2 positive breast cancer is up to 25%, and thus activates PI3K-Akt signaling pathway,promotes HER2 mediated tumor cell epithelial transformation, alters the intrinsic phenotype of HER2 overexpression breast cancer,and finally leads to resistance to anti HER2 targeted therapy.Some studies have shown that the PIK3CA gene mutation is associated with the efficacy of anti-HER2 targeted therapy.Therefore,real-time monitoring of PIK3CA gene mutation will promote indivi-dualized anti-HER2 targeted therapy.

Objective To determine long-term survival of 214 patients of lung cancer with brain metastases and to detect the potential prognostic factors.Methods A retrospective review was pedormed evaluating patients diagnosed as lung cancer with brain metastasis from Jan 1992 to Dec 2001 at Zhejiang Cancer Hospital.Two hundred and fourteen cases were enrolled.All hospital records were thoroughly reviewed in a retrospective manner.The management of the brain metastases were as follows: 8 patients underwent surgical resection and postoperative whole brain radiotherapy (WBRT); 2 cases received resection and chemotherapy; 10 had resection alone; 10 underwent WBRT alone,36 had chemotherapy alone; 15 received the combination of resection,chemotherapy and WBRT; 104 were performed with chemotherapy combined with WBRT; 29 had only supportive care.Survival time was measured from the date of the first treatment for malignancy to the date of death or the last follow-up.Seven further potential prognostic factors were investigated for survival including age,gender,T or N status,number of extra cranial metastases,pathological type and treatment modality.Statistical analysis was performed using the Kaplan-Meier method and Cox-regression analysis.Results The overall median survival time was 10 months (95% CI9.06--10.94) and the 1,3,5 year survival rates were 7.46%,1.14% and 0,respectively.In the univariate model,none of the following variables had effect on survival: age,gender,T stage of the tumor,nodal status,number of extra cranial metastases and histological type.Univariate analysis showed a better survival for the combination of surgical resection,chemotherapy and radiation (P=0.00).Based on Cox-regression analysis,treatment modality was the only independent predictor of survival Conclusions Aggressive combined therapy of brain metastases may achieve a survival advantage.Excellent overall survival of lung cancer with brain metastases has been achieved with a combination of WBRT with surgical resection and chemotherapy.

Objective To find out some possible risk factors of death postcardiac surgery undergoing cardiopulmonary bypass.Method Totally 36 patients,who underwent postcardiotomy undergoing cardiopulmonary bypass in Subei Hospital of Jiangsu Provience from March 2005 to June 2006,were retrospectively analyzed.The criteria for the selection of patients were as follow:(1)patients underwent on-pump cardiopulmonary bypass;(2)patients with heart function in Ⅰ-Ⅲ degree; (3)all patients didn't have organ dysfunction before operation;(4)patients died within 28 days postcardiotomy.Therefore,6 patients who died were admitted as death group,the other 30 patients were admitted as control group.The analysis included: (1)preoperative factors,including gender,age,diagnosis preoperative,NYHA grade,APACHEⅡscore,left ventricular end-diastolic diameter.(2)operative factors:operation time,block aorta time. (3)postoperation factors:hemorrhage volume,mechanical ventilation time,and factors of hemodynamics and oxygen metabolism 6 hour postoperative:heart rate(HR),central venous pressure(CVP),pulmonary arteria wedged pressure(PAWP),cardiac output index(CI),arterial blood lactic acid,partial pressure of oxygen(PaO2),mixed venous oxygen saturation(SvO2),oxygen delivery index(DO2I),oxygen comsume index(VO2I),oxygen extraction ratio (O2ext).Comparisons between two group was made with SPSSl0.0 for windows.Firstly,the data were analyzed with process of single variable analysis and Some parameters,which showed the significant difference,were sorted out from two groups.Then these parameters were put to the IDGISTIC regression analysis.Consequently,the independent risk factors of death of postcardiac surgery could be found.Results The single variable analysis showed that the parameters of APACHE Ⅱ score,left ventricular end-diastolic diameter,block aorta time,mechanical ventilation time,arterial blood lactic acid,SvO2 had significant difference betwen groups(P<0.05).The LOGISTIC regression showed that left ventricular end-diastolic diameter and arterial blood lactic acid ale the two independent risk factors of death(P<0.05).Conclusions Arterial lactatemia and left ventricular end-diastolic diameter can be used to predict the prognosis of postcardiotomy undergoing cardiopulmonary bypass.

Objective Carbonic anhydrase 1 (CA1) not only enhances the hydration reaction but also promotes the formation of CaCO3,which is an essential step for new bone formation in vitro.However,there is no direct evidence to demonstrate the involvement of CA1 in bio-mineralization in cells and tissues.This study is aimed to evaluate the important role of CA1 in bio-mineralization and ossification in cultured cells.Methods Calcification in Saos-2 cells was induced using osteogenic medium (OM) and the calcification was determined by Alizarin Red-S staining.The expressions of ossification protein marker Runt-related transcription factor-2 (Runx2),osterix (OSX),alkaline phosphatase (ALP),osteocalcin (OCN) and bone sialoprotein (BSP) were detected in the process of bone formation by real-time PCR.The expression of CA 1 in the calcified cells were measured using real-time PCR and Western blotting.We also detected calcification in Saos-2 cells in the presence of acetazolamide,an anti-carbonic anhydrase drug to CA1,to determine the role of CA1 in biomineralization in culture cells.T test analysis was used to compare the two groups,M-ANOVA of repeated measurs was conducted for different time point.Results Following the stimulation of OM,Saos-2 cells produced a great amount of calcium-rich deposits [0.68±0.03 vs 2.76±0.13,P<0.01].Increased transcriptions of ossification protein markers were also detected in these stimulated Saos-2 cells,indicating that the OM launched the process of bone formation in the cells.CA1 had a significantly increased expression during this process [0.25±0.03 vs 0.94±0.06,P<0.01].Following treatment with acetazolamide,the expression of CA1 evidently declined [1.09±0.05 vs 0.55±0.07,P<0.05],and the mineralized nodule formation was declined [2.76±0.13 vs 2.19±0.07,P<0.01].Conclusion These findings indicate that CA1 participates in the biomineralization and ossification,and may play an important roles in bone formation.

Objective:
To investigate the clinicopathological characteristic and risk factors for recurrence in different subtypes of mucinous breast cancer(MBC).
Methods:
Clinical data of 97 MBC patients at Zhejiang Cancer Hospital from August 2005 to November 2012 were retrospectively analyzed. All of patients were divided into 3 subtypes according to the mucinous components in the tumors, named as partial mixed MBC with less than 50% of mucinous components, main mixed MBC where the mucinous component accounted for 50% to 90%, and pure MBC with more than 90% of mucinous components. In this study, 43, 16 and 38 patients were included in partial mixed MBC, main mixed MBC, and pure MBC, respectively. Follow-up was collected by out-patient, in-patient system and phone call. The relationship between different subtypes and clinicopathological significance were analyzed by
