Objective To study the effect of point electric stimulation for urinary incontinence after postoperative cerebral hemorrhage.Methods Eighty patients with urinary incontinence after postoperative cerebral hemorrhage were randomly divided into treatment group and control group(n=40 case). Point electric stimulation was given to the treatment group, and Oxybutynin hydrochloride sustained release tablets was given orally to the control group. Index of urinary diary and bladder capacity in both groups before treatment and after 3 weeks of treatment were observed.Results After 3 weeks of treatment,the total effective rate(87.2%vs. 65.8%,χ2=4.916) in the treatment group were better than the control group (P<0.05). The times of voided (10.15 ± 2.21 times/24 hvs. 18.63 ± 3.42 times/24 h,t=12.956), the times of urinary incontinence (2.18 ± 1.04 times/24 h vs. 6.19 ± 2.16 times/24 h,t=10.421), the average voided volume (293.38 ± 16.32 mlvs. 180.82 ± 15.43 ml, t=31.083), the initial sensory capacity of bladder (276.73 ± 20.95 mlvs. 186.43 ± 21.14 ml,t=18.825), the maximum capacity of bladder (492.81 ± 23.72 mlvs. 293.81 ± 24.46 ml,t=36.244), the residual urine volume(13.25 ± 5.83 mlvs. 34.63 ± 6.25 ml,t=15.527) in the treatment group were significantly better than those in the control group (P<0.01).Conclusions The treatment of point electric stimulation can reduce the symptoms of urinary incontinence.

Objective To assess the clinical efficiency and side effects of topical mometasone furoate aqueous nasal spray for patients with naphazoline-induced rebound rhinitis. Methods A prospective, non-randomized and self-controlled study was applied. A total of 22 patients with naphazoline-induced rhinitis received two spray-puffs of 50 μg mometason furoate twice daily to each nostril in the morning for one week, followed by two spray-puffs of 50 μg mometason furoate once daily to each nostril every morning for another three weeks after withdrawn of naphazoline therapy. Nasal congestion was evaluated by visual an-alogue scale (VAS) recorded before and after treatment. Side effects like nose bleeding and perforation of the nasal septum was detected with rhinoscope. Results The statistical difference of VAS before and after treatment was significant. No adverse reac-tions as nose bleeding and perforation of the nasal septum were observed by the end of treatment. Conclusion It is safe and effective to use mometasone furoate aqueous nasal spray for treating rebound rhinitis induced by misuse of naphazoline nasal drop.

This paper is to survey two groups of medicine-oriented English major undergraduates who have their probation either before or after the Quality Monitoring System is introduced to them about their degrees of learning satisfaction through questionnaires and seminar discussions. As a result, it proves that the implementation of the Quality Monitoring System in student probation helps to raise the degrees of student learning satisfaction, which clearly promotes the probation quality and secures the fulfillment of the mission in practice.

Objective To analyze the correlation of perfusion parameters obtained by functional multi-slice computed tomography (fMSCT) with vascular endothelial growth factor (VEGF) detected with immunohistochemistry on rabbit model with VX2 breast cancer and noninvasively evaluate the vascularization of untreated VX2 breast cancer in vivo. Methods Sixteen New Zealand femal rabbits were selected and suspension (1 ml) of mass was injected around the breast areola. CT perfusion was performed after two weeks and perfusion parameters including blood flow (BF), blood volume (BV), mean transit time (MTT)and permeability surface (PS) were assessed. Expression of VEGF in neoplasm was detected with immunohistochemistry. Paried t test was used for the comparison of perfusion parameters between the tumor and muscle and Pearson correlation analysis was used to assess the correlation of VEGF with perfusion parameters. Results The mean value of BF, BV, MTT and PS were (228.21 ± 13. 13 ) ml · min-1100 mg-1 ,(13.45 ± 1.01) ml · 100 mg-1 ,(3. 50 ±0. 20) sand (7.85 ±1.18) ml · min-1 · 100 mg-1 in tumor, respectively. They were (66. 10 ±22. 11 ) ml · min-1 · 100 mg-1 , ( 1.88 ± 1.80) ml · 100 mg-1,(23. 87 ±0. 63)s,(1.55 ±0. 38)ml · min-1 · 100 mg-1 in muscular tissue, respectively. The mean value of BF, BV and PS in tumor were obviously higher than those in muscle, and the mean value of MTT in tumor was lower than that in muscle. There were significant differences in CT perfusion parameters between tumor and muscle (t = 61.83,13.63,27.72,20. 54, P ＜ 0. 01 ). The mean value of VEGF in tumor was 7. 33 ±0. 27 and there were positive correlation with BF ( r = 0. 712, P ＜ 0. 01 ), BV ( r = 0. 647, P ＜ 0. 01 ), PS ( r =0. 627 ,P ＜ 0. 01 ), and negative correlation with MTT ( r = - 0. 564, P ＜ 0. 05 ). Conclusion MSCT perfusion imaging can be used to noninvasively evaluate the vascularization in rabbits with untreated VX2 breast cancer in vivo.

Objective To investigatethe clinical value of troponin-I(cTnI)in patientswith septic shocka-nd left ventricular diastolic dysfunction. Methods As a retrospective analysis ,38 patients with left ventricular di-astolic dysfunction and septic shock(Sa group),as well as 20 patients with normal cardiac function(Sn group) were enrolled in this study. Moreover ,20 patients with left ventricular diastolic dysfunction and without septic shock were used as control group(Ca group). The ratio of early diastolic mitral inflow velocity to early diastolic mi-tral annulus velocity(E/e′)was measured as the evaluation index of left ventricular diastolicfunction by echocar-diography within 72 hours after admission to ICU. Level of cTnI was detected in all cases and the relationship was evaluated by E/e′. Receiver operating characteristic curve(ROC)was constructed to indicate the predictable value of left ventricular diastolic dysfunction in patients with septic shock. Results The level of cTnI was significantly elevated in both Sa group and Sn group(P<0.05),while the level of cTnI and E/e′in Sa group were significantly higher than those in Sn group(P < 0.05). cTnI was positively correlated with E/e′(r = 0.367 ,P = 0.004). The area under the curve(AUC)of cTnI was 0.834,with the cut-off value of 0.49 ng/mL(sensibility=77.6,specificity=80.7). Conclusion The level of cTnI was significantly higher in patients with septic shock. cTnI was significantly correlated to left ventricular diastolic dysfunction in patients with septic shock. cTnI ≥ 0.49 ng/mL could be an available predictor for left ventricular diastolic dysfunction in patients with septic shock.

Objective To study the pro-invasive effect of irradiation on human glioblastoma cell line U87 and its possible mechanism.Methods Cultured U87 cells received different doses of irradiation (0,2,and 4 Gy).The change in cellular invasiveness was measured using the real-time cell analyzer system.The activities of matrix metalloproteinase-2 (MMP2) and matrix metalloproteinase-9 (MMP9) in U87 ceils were measured by gelatin zymography before and after irradiation.The content and distribution of intracellular β-catenin after irradiation were determined by immunohistochemistry.The mRNA levels of Wnt/β-catenin target genes were measured by real-time quantitative PCR.Results After irradiation,the invasiveness of U87 cells increased significantly (P ＜ 0.01),which was dose-dependent within a certain dose range; the activities of MMP2 and MMP9 in U87 cells increased significantly (P =0.031 for MMP2 ; P =0.004 for MMP9) ;the content of β-catenin in U87 cells increased significantly (P ＜ 0.01),with translocation from the cell membrane and adherens junctions to the nucleus; the mRNA levels of Wnt/β-catenin-related genes (FZD7 and TCF1) increased significantly (P ＜ 0.01),and the transcription of Wnt/β-catenin target genes,especially those related to migration and invasion such as MMP2,MMP7,MMP9,and CD44,was significantly enhanced (P ＜ 0.05).Conclusions Irradiation can promote the invasion of glioblastoma U87 cells,possibly by activating the Wnt/β-catenin pathway and enhancing the transcription of migration-and invasion-related genes.
