Purpose:To assess the therapeutic value of perc utaneous portal vein chemoembolization (PVE) for primary hepatic carcinoma (PHC) with portal vein tumor thrombus. Methods:45 unresectable PHC with portal vein tumor thrombus cas es were randomly divided into two groups. The observation group was treated with transcatheter arterial chemoembolization (TACE)+PVE, while the control group wa s treated with TACE only. The changes of AFP, response rates of portal vein tumo r thrombus and survival rates of one year were analyzed respectively. Results:The levels of AFP before and after treatment were(730 ?190)?g/L and (515+?395)?g/L in the observation group,(752?183)?g/L a nd (710?213)?g/L in the control group respectively. The difference between t he two groups was significant (P

OBJECTIVETo study the effect of Buyang Huanwu decoction (BYHWD) inducing angiogenesis on the neuroblast migration from the subventricular zone and its mechanisms after focal cerebral ischemia.

METHODThe middle cerebral artery occlusion (MCAO) was performed to mice for 30 minutes to establish the model. The rats were divided into sham group, model group, BYHWD group and endostatin group. BYHWD (20 g x kg(-1), ig) and endostatin (10 μg, sc) were administered 24 h after ischemia once a day for consecutively 14 days. At 14 d after ischemia, the density of micro-vessel and the number of neuroblasts in the ischemia border zone were determined by immunofluorescence staining. The mRNA and protein expression of cell-derived factor-1 (SDF-1) and brain-derived neurotrophic (BDNF) were examined by real-time PCR and Western blot.

RESULTCompared with the model group, BYHWD significantly increased the density of micro-vessel and the number of DCX positive cells in the ischemia border zone (P < 0.01), and significantly increased the SDF-1 and BDNF mRNA and protein expression (P < 0.01). Compared with BYHWD group, endostatin significantly reduced the density of micro-vessel and the number of DCX positive cells in the ischemia border zone (P < 0.01), as well as the SDF-1, BDNF mRNA and protein expression (P < 0.01).

CONCLUSIONBYHWD could promote the neuroblast migration from the subventricular zone via inducing angiogenesis after cerebral ischemia, the mechanism may be correlated with up-regulating the expression of SDF-1 and BDNF.

Objective To analyze the mammographic findings of triple-negative breast cancer [TNBC,which is estrogen receptor (ER) negative,progesterone receptor (PR) negative,and human epidermal growth factor receptor 2 ( HER2 ) negative ] and triple-positive breast cancer ( TPBC,which is ER positive,PR positive,and HER2 positive ),and to evaluate the relationship of immunohistochemologic receptor status and mammographic findings.MethodsThe immunohistochemistry results of 631 cases with breast cancers were reviewed,including 117 cases of TNBC and 44 cases of TPBC.All of the patients took mammography at initial diagnosis.We retrospectively evaluated the visibility,morphology,distribution and size of the lesion (masses and calcifications) and breast density on mammography of TNBC,and compared them with those of TPBC.The age onset and tumor sizes of TNBC and TPBC were compared by using Chi-square test and t test.ResultsThe visibility rate of TNBC and TPBC on mammography were 88.0％(103/117) and 90.9％ (40/44),and the difference between them was insignificant ( x2 =0.055,P ＞0.05).TNBC was more frequently associated with merely a mass (56/103) than TPBC (12/40) (x2 =6.860,P＜0.01 ),and the mean diameter of the mass of TNBC [ ( 2.6 ± 1.4 ) cm ] was larger than that of TPBC [(2.0 ± 0.6) cm](t =2.087,P ＜ 0.05). TNBC were less frequently associated with microcalcifications (37/103) than TPBC ( 24/40 ) ( x2 =7.423,P ＜ 0.01 ).Mammographic density and lesion visibility were similar between the two different immunophenotypes of breast cancers.The mean age of TNBC (52±9) was more than that of TPBC (48 ±8) (t =2.759,P ＜0.01).Infiltrating ductal carcinoma was the main pathologic type of both groups.Basal-like breast cancer accounted for 49％ (57/117 ) of TNBC while none happened in TPBC.ConclusionsTNBC shows merely a mass with indistinct margins,lager size and is less associated with microcalcifications.These mammographic features might be useful in diagnosing triple negative breast cancer.

Objective To predict the risk of 28-day mortality in septic patients in intensive care unit (ICU) with the combination of Weighted index of comorbidities (WIC) and sepsis-related organ failure assessment (SOFA) score.Methods The clinical data of adult severe sepsis/septic shock patients in Department of Emergency Medicine of Changzheng Hospital and Department of Critical Care Medicine of Jinan Military General Hospital from October 2011 to February 2013 were analyzed retrospectively.The etiological factor,past history,having severe sepsis or not were recorded.Age score,WIC score,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and SOFA score were calculated at or 24 hours after admission.The logistic regression was used and the receiver operating characteristic curve (ROC curve) was drawn to calculate the patients' outcome.Results In 310 enrolled patients,223 (71.9％) patients survived and 87 (28.1％) died.Univariate analysis showed that the P values of the age score,WIC score,APACHE Ⅱ score and SOFA score,chronic cardiac insufficiency,type 2 diabetes,cerebrovascular disease,tumor,multiple injury,pulmonary infection and having severe sepsis or not were all less than 0.2.The above 11 variables were put into the multivariate logistic regression equation 1,of which predicted probability was reserved.It revealed that 5 variables were independently associated with 28-day prognosis,of which influence power in descending order were SOFA score [odds ratio (OR) =1.308,95％ confidence interval (95％ CI):1.158-1.478,P=0.000],having severe sepsis or not (OR =0.206,95％ CI:0.100-0.424,P=0.000),APACHE Ⅱ score (OR =1.090,95％CI:1.021-1.164,P=0.010),WICscore (OR=1.441,95％CI:1.067-1.947,P=0.017),agescore (OR=1.228,95％CI:1.027-1.468,P=0).024),the Walswere 18.554,18.369,6.725,5.662,5.067,respectively.The 3 variables,age score,WIC score and SOFA score,were brought into the multivariate logistic regression equation 2,of which predicted probability was reserved too.It revealed that age score (OR=1.330,95％CI:1.145-1.546,P=0.000),WIC score (OR =1.496,95％ CI:1.145-1.546,P=0.000) and SOFA score (OR =1.429,95％ CI:1.303-1.567,P=0.000),were independently associated with the septic patients' 28-day prognosis.There was no significant difference in the area under receiver operating characteristic curve (AUC) between the SOFA score and APACHE Ⅱ score (0.784 vs.0.780,Z=0.014,P=0.989).However,compared with APACHE Ⅱ score,the AUC of equation 1 (0.888) and 2 (0.851) were much more (Z=4.333,P=0.000; Z=2.669,P=0.008).Conclusion The sensitivity of 28-day prognosis by WIC score was improved greatly with the combination of SOFA score and age score.
