Objective To compare the efficacy of vacuum sealing drainage( VSD) and the traditional treatment for breast abscess drain-age abscess.Methods A total of 59 cases with breast abscess in our hospital from February 2013 to December 2014 were randomly divided into two groups.The observation group underwent VSD and the control group treated by traditional abscess drainage of abscesses.The healing time,scarring length,the average length of hospital stay,number of dressing changes,pain degree were observed.The breast deformation and the recurrence of patients after 6 months were compared.Results The abscess healing time,the length of scar and the average days of hospi-talization were respectively (10.3 ±1.2) d,(1.5 ±0.2) cm,(12.7 ±3.5) d,the control group were respectively (16.5 ±2.6) d,(4.5 ± 0.6) cm,(26.9 ±3.3) d.The difference between two groups was statistically significant(P<0.05).The number of dressing changes and pain score of observation group were respectively (3.9 ±1.1) times and (3.3 ±0.6 ) points,the control group were respectively (10.5 ±1.5) times and (6.7 ±0.9) points.The difference between two groups was significant(P<0.01).All patients were followed up for 6 months,no recurrence was in observation group,and 1 case with recurrence in control group,the difference was not statistically significant(P>0.05).No breast deformation occurred in observation group,but 5 cases in the control group.The difference between two groups was statistically signifi-cant(P<0.05).Conclusion The effect of VSD for breast abscess is significant,which can accelerate the healing of the abscess and reduce the suffering of patients without affecting the appearance.

Objective To explore the correlation between the parameters of ambulatory blood pressure monitoring (ABPM) and prostatic volume in elderly patients with essential hypertension.Methods The 131 elderly patients with essential hypertension from March 2007 to December 2009 were enrolled in this study, including 102 benign prostatic hyperplasia (BPH) patients and 29 nonBPH (NBPH) patients. All patients underwent ABPM and ultrasound examination of prostate.Prostatic volumes (PV) were calculated and were compared between BPH group and NBPH group.Correlation between parameters of ABPM and PV was analyzed. Results (1)The maximal mean artery pressure (MAPmax) at night was higher in BPH group than in NBPH group [( 104.7 ± 12. 0)mm Hg vs. (99.6± 10. 1) mm Hg, P= 0.039]. (2)There were correlations between PV and MAPmax in all-day (r=0. 184, P=0. 035), MAPmax at daytime (r=0. 183, P=0. 037), MAPmax at night (r=0. 181, P=0. 040), respectively. Conclusions MAPmax of ABPM may be associated with PV in elderly patients with essential hypertension.

Taking into account the near infrared spectra(NIR) on numerous predictor variables with serious collinearity and having nonlinear quantitative relationship with the chemical compositions, a novel nonlinear partial least squares(PLS) approach, termed as Spline-PPLS, was constructed by combining the penalized partial least squares(PPLS) regression with B-splines transformation. Firstly, the observed spectral predictors were considered as discrete observations of curves of the wavelength and were nonlinearly transformed using B-spline basis functions. The choice of the degree of the polynomial pieces and of the number of knots was performed using the cross-validation strategy. Then, the PPLS algorithm was performed on the high dimensional transformed data matrix to build the calibration model by imposing a penalty term to the optimization criterion of PLS. The roughness penalty term indeed controlled the curvature of the functions and its smoothing parameter could also be obtained by the cross-validation. Finally, the proposed Spline-PPLS approach was applied to the wheat NIR diffuse reflectance spectra reconstruction and quantitative analysis. The result indicates that the Spline-PPLS approach not only can yield high accuracy reconstructing spectrum, but also improves the model prediction accuracy in the case of nonlinear relationships.

Objective To establish a stable implanted model of VX2 rabbit brain tumor, and to evaluate the pathological and imaging features and tumor angiogenesis. Methods Thirty New Zealand white rabbits were implanted with 100 ?l viable VX2 tumor cells (107/ml) through a hole 5 mm to the right of the sagittal suture and 5 mm posterior to the coronal suture bored by a dental drill. MRI was performed every ~2 days after 7 days of implantation to evaluate the growth of the tumor, and perfusion CT studies were performed in different days of tumor growth. After that the animals were sacrificed on days 14, 18, 22, 26, and 30 of tumor implantation. 2% Evans blue (2 ml/kg) was given intravenously in 16 of these animals ~1 hour prior to sacrifice to detect the breakdown of the blood-brain barrier (BBB). The specimens of the rabbit brains were examined pathologically and histologically. VEGF and MVD were evaluated in immunohistochemical examination. Results Of the 22 animals included into the study, the tumor grew in 20 animals, which could be seen clearly on MR imaging. Pathologic examination showed characteristics of squamous carcinoma. VEGF was expressed in all tumors with the mean rate of positive cells of (52.51?19.15)% (19.5%-92.9%). Mean MVD was (51.30?14.42)pice piece/microscope (25-81 pice piece/microscope). Using Pearson′s linear correlation analysis, positive correlation was found between tumor growth time and volume (r=0.791, P=0.000), between MVD and tumor growth time (r=0.875, P=0.000), and between MVD and tumor volume (r=0.901, P=0.000), respectively. Spearman′s rank correlation analysis showed positive correlation between VEGF grade and blue stain of the tumor (r_s=0.594, P=0.015). Conclusion A stable model of VX2 rabbit brain tumor has been established with the method of skull drilling. The method was simple and easy to use, with a high tumor growth rate and remarkable angiogenesis. The model is helpful for the pathological and radiological study of tumor angiogenesis.
