Objective To investigate androgen receptor (AR) expression in triple negative breast cancer(TNBC) patients and its predictive value for clinical outcomes.Methods Five hundred and sixty-eight primary breast cancer patients who received surgery treatment from January 2008 to January 2010 were included in this study.Tissue sections of surgical resection specimens were underwent estrogen receptor (ER),progesterone receptor (PR),and human epidermal growth factor receptor 2 (HER2) immunohisto chemical staining,according to the judgment for triple negative breast cancer and non triple negative breast cancer.Data on age,family history,menstruation,tumor size,tumor stage,tumor grade,pathological type and lymph node metastasis were collected for analysis.Immunohistochemical analysis of AR was done in tissue sections of triple negative breast cancer patients,Kaplan-Meier method was used to compare survival between AR(+) and AR(-) groups,and Log-rank method was used to determine the association between AR-positive expression and 5-year overall survival as well as disease free survival.Results Among 568 breast cancer patients,174 (30.6％)TNBC patients were identified,including 84 patiens with AR (-) expression and 90 patients with AR (+) expression.During 5 years' follow-up,reccurrence rate was 35.7％ (30/84) in AR (-) group and 20.0％ (18/90) in AR(+) group;5-year overall survival rate was 73.8％ in AR(-) group and 81.1％ in AR(+) group.There was no significant association between AR(+) expression and 5-year death or recurrence rate,while after adjusting for age,menstruation,tumor size and lymph node metastasis,AR (+) expression was significantly associated with decreased 5-year death and recurrence rate,adjusted hazard ratio (HR) was 0.794,95CI (0.430-1.021) and 0.722,95CI (0.451-0.965) respectively.Conclusion AR (-) expression is associated with increased risk of death and recurrence and is a promising predictive marker for poor clinical outcomes.

Objective To determine the risk factors for the development of systemic inflammatory response syndrome (SIRS) in the patients after cardiopulmonary bypass has been constructed. Methods Eighty three NYHAⅠor Ⅱ patients, aged 6month-66yr, weighting 7～97 kg, undergoing cardiopulmonary bypass, were enrolled in this study. SIRS score was performed during 24 h after the surgery. The patients were divided into 2 groups: SIRS group(S, SIRS score≥2) and non-SIRS group(U, SIRS score＜2). The risk factors were identified by logistic regression analysis. Results The incidence of SIRS was 83.13% . Logistic analysis indicated that arterial oxygen pressure (PaO2), retention time, and postoperative heart rate were closely related with the development of SIRS in patients on ICU after cardiopulmonary bypass (OR＝0.518,4.334,3.607,P＜0.05). Conclusions The arterial oxygen pressure (PaO2), ICU stay, and heart rate after cardiopulmonary bypass has been constructed can be served as the risk factors for the development of SIRS in patients.

Objective To investigate the 9 . 4 T of DTT in the diagnosis of SD rat C6 cerebral gliomas model about the change of CST on tumor progression and pathology confirmed. Methods ①10 μl C6 cell suspension of 106 cells number were implanted into the right caudate nucleus of brain hemisphere of 20 adult male SD rat with ster-eotactic technique. ②Application of 9. 4 T of DTT and DTI, meanwhile the routine T1-weighted imaging(T1WI), T2-weighted imaging(T2WI), contrast-enhanced T1WI,FLAIR imaging and diffusion tensor of the brain were ac-quired. Anatomic relationship between cerebral glioma and surrounding white matter fiber tracts was analyzed and measured the values of FA and MD in different areas on fractional anisotropic ( FA) map, color-coded directional map, three-dimensional (3D) white matter fiber tracts map, then stained with routine HE. Results All of SD rat C6 cerebral gliomas models 3 D white matter fiber tracts map by means of FA maps of DTI were successfully comple-ted. Apparently significant differences of FA values were found in solid tumor, surrounding edema, compared with normal white matter regions ( P<0.05 );but there was no significant difference among solid tumor and surrounding edema region (P>0.05);there were significant differences of MD values between solid tumor, surrounding edema and normal white matter region ( P<0.05 ) . Conclusion The 9 . 4 T of DTT offers the optimal visualization of An-atomic relationship between cerebral glioma and surrounding white matter fiber tracts in the different periods of the tumor moder.

SUMMARY Salivary gland tumors are a group of the most common tumors in the oral and maxillofacial region with obvious characteristics of clinical , histopathologic , and therapeutic aspects .During the past 50 years, our research group performed a systemic study on salivary gland tumors including imaging diag-nosis, fine needle aspiration cytology , FT-mid-IR fiber optics spectroscopy , histopathologic features and biological behaviour of the tumors , functional parotid surgery , and 125 I seed implant branchytherapy . More reasonable principles of management for various types of the tumors were put forward based on the histopathologic features of the tumors .The surgical techniques were modified and the postoperative com-plications were reduced obviously .Thus, the quality of life of the patients was improved greatly .

The ras-mitogen activeted protein kinase pathway is responsible for regulation of many cel-lular processes, including differentiation, cytoskeletal organization, and protein trafficking. Much attention has been paid to them and their role in cancer therapy recently, and its inhibitor pathways are applied to clinical tes-ting, such as, Raf kinse inhibitors, MEK inhibitor, Src kinase inhibitor.

[Summary] Chronic suppurative otitis media affects patients ’ quality of life, and is life-threatening in patients with cholesteatoma which causes intracranial or extracranial complications .The purpose of surgery is to clear up all the lesions and to reconstruct hearing function .Tympanoplasty is the main surgical method , which includes basically canal wall down ( CWD) and canal wall up (CWU) styles.CWD provides lager surgical field but impairs normal auditory canal structure ; CWU preserves the posterior wall of external auditory canal and provides better quality of life although it has higher possibility of recurrence of cholesteatoma .We reviewed the surgical methods , surgical effects , recurrence rates , and surgical indications of canal wall up mastoid-tympanoplasty , hoping to provide meaningful reference for clinical application .

Objective To compare the influence of resin core on overall bending strength of fiber post-core restoration.Methods 60 mandibular first premolar extracted because of orthodontic treatment was selected.3M light -cured composite resin P60,medental dual-cured resin,pulpdent dual-cured resin combined with viva carbon fiber reinforced glass fiber post were applied.The changes of teeth in vitro were observed when strength was given on.Results The flexural strength of 3M light-cured composite resin was (80.182 ±9.512)N,Medental dual-cured resin was (87.805 ± 11.649) N,Pulpdent dual-cured resin was (85.458 ± 10.845) N.The flexural strength of 3 M light-cured composite resin was lower than that of medental dual-cured resin and pulpdent dual-cured resin (t =5.758,3.084,both P ＜ 0.05).There was no statistical differences of flexural strength between medental dual-cured resin and pulpdent dual-cured resin(t =0.718,P ＞ 0.05).There was large area of resin broken off after 3M light-cured composite resin core fracture.There was only fracture of medental dual-cured resin core and pulpdent dual-cured resin core.Conclusion The bending strength of dual-cured resin is better than that of highly filled light curing composite resin in large tooth hard tissue defect restoration with fiber post-core,and core broken off is rare.Dual-cured resin is better post-core materials.

Objective To study the immunomodulation effects of different dosage of dexmedetomidine (Dex)in the septic shock model of rats after cecal ligation and puncture (CLP).Methods After CLP, 48 wistar rats were randomly (random number)allocated in four groups:(1)CLP group;(2)small-dose Dex group [2.5 μg/(kg·h)];(3)medium-dose Dex group [5.0 μg/(kg·h)];(4) large-dose Dex group [10.0 μg/(kg·h)].HLA-DR (human leukocyte antigen-DR)and plasma cytokine (IL-4, IL-6,IL-10 and TNF-α)were measured,meanwhile mean arterial blood pressure (MAP),heart rate (HR)and mortality were also documented at 1,3,and 5 h after the CLP procedure.Results There were no obvious differences in HLA -DR level,levels of inflammatory mediators,MAP and HR among there Dex treatment groups.Compared with CLP group,HLA-DR level decreased in three Dex treatment groups (P =0.020)and pro-inflammatory mediator (IL-6)increased at 3 h (P =0.011 )then declined at 5 h with decreased HR (P <0.01),and without obvious change in MAP (P =0.124),and all of them led to a significantly decrease in the mortality.The mortalities in CLP group,small dose group,medium dose group and large dose group were 91.7%, 66.7%, 25.0% and 18.0%, respectively. Conclusions Dexmedetomidine used in rats with septic shock rats partially induced immunomodulation initiated within 5 h after CLP evidenced by decreased HR,maintenance of MAP and reduction of mortality rate in dose-dependent fashion.

Her-2 targeting therapy is an important part of the treatment for breast cancer with Her -2 overexpression.However,the therapeutic effectiveness is largely influenced by Her -2 resistance.Previous studies have confirmed that PI3K/AKT/mTOR signaling pathway is activated during the process of drug resistance to Her-2-targeting therapy.Therefore,investigating the PI3K/AKT/mTOR signaling pathway and drugs -targeted pathway are important for the treatment of breast cancer .
