Objective To evaluate the diagnostic value of quantitative analysis parameters of dynamic contrast-enhanced magnetic resonance imaging (MRI) in differential diagnosis of prostatic disease.Methods 12 patients with prostate cancer and 16 patients with benign disease underwent DCE-MRI examination.Region of interest (ROI) were drawn in areas of cancerous foci,normal prostate peripheral zone and normal prostate central gland to measure the values of Ktrans (transport constant),Kep (rate constant),Ve (extravascular extracellular volume fraction).Values of the three parameters were analyzed by ANOVA and the differences were compared between the different tissues.Results The values of Ktrans,Kep and Ve were (0.42±0.10)/min,(0.64±0.11)/min,(0.61±0.14) respectively in the area of cancerous foci,while (0.17 ±0.08)/min,(0.32 ±0.10)/min,(0.59±0.11) respectively in normal prostate peripheral zone,and (0.33±0.12)/min,(0.50± 0.16)/min,(0.62 ±0.07) respectively in normal prostate central gland.The differences in Ktrans,Kep values were statistically significant between cancerous foci,normal prostate peripheral zone and normal prostate central gland (F =31.646,27.196,respectively,all P ＜ 0.05),but no statistically significant difference was found in the Ve value between the three different tissues (F=0.533,P＞ 0.05).Conclusions Quantitative analysis of DCE-MBI can be used to differentiate benign from malignant prostatic diseases,which hasa great application prospect.

Objective To explore the effect of interferon-?(IFN-?)on phenotypic transition of human Tenon’s conjunctival capsular fibroblast(HTCF). Methods Cultured HTCF derived from 4 operated human cataracts was induced for 48 hours in absence or presence of IFN-? and/or transforming growth factor-?1(TGF-?1). Then immunocytochemistry and Western blot technology were used to detect the ?-smooth muscle actin(?-SMA)expression and identificate the cell phenotype. Results In contrast to normal HTCF, IFN-?(10 ng/mL) inhibited the expression of ?-SMA(P

Objective: To observe the clinical efficacy of acupuncture plus rehabilitation training in treating post-stroke deglutition disorders of qi-deficiency blood stasis pattern. Methods: Sixty-six patients with post-stroke deglutition disorders of qi-deficiency blood stasis patter were divided into an observation group and a rehabilitation group using the random number table method. The two groups both received conventional medications and supportive treatment for stroke. In addition, the observation group received acupuncture plus rehabilitation training while the rehabilitation group only received the same rehabilitation training. The interventions were conducted 3 times a week for a total of 4 weeks in both groups. They were evaluated using Kubota water swallowing test (KWST), Fujishima Ichiro food intake level scale (FILS) and symptoms score of traditional Chinese medicine (TCM) before and after treatment, and at the 1-month follow-up. The therapeutic efficacy was assessed at the 1-month follow-up. Results: The KWST grading and FILS result after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.001); the results of these two items at the follow-up were not significantly different from those after treatment in the two groups (all P>0.05). There were significant differences in the KWST grading and FILS result between the two groups after treatment and at the follow-up (all P<0.05). The TCM symptoms score changed significantly after treatment and at the follow-up compared with that before treatment in both groups (all P<0.001). The TCM symptoms grading efficacy at the follow-up was significantly different from that after treatment in the observation group (P<0.05), while the difference was statistically insignificant in the rehabilitation group (P>0.05). The TCM symptoms grading efficacy in the observation group was significantly different from that in the rehabilitation group after treatment and at the follow-up (both P<0.05). Conclusion: Based on the conventional treatment for stroke, acupuncture plus rehabilitation training or use of rehabilitation training alone both can improve the clinical symptoms in post-stroke deglutition disorders of qi-deficiency blood stasis pattern, but acupuncture plus rehabilitation training can produce more significant efficacy and better long-term efficacy in improving TCM symptoms.

The essential medium of B115 composed of 1% tryptone, 0.25% yeast extract and 0.5% sodium chloride was determined by using an orthogonal design. The orthogonal design was also employed in testing the optimum additions. It was composed of 0.1%(NH_(4))_(2)SO_(4),1.4%K_(2)HPO_(4), 0.6% KH_(2)PO_(4) and 0.1% (Na_(3)C_(6)H_(5)O_(7)). The yield of B115 cultured in optimum medium was compared with the one in essential medium. Statistic analysis showed that the growth of B115 was most significantly improved by adding K~(+)、NH~+_(4) and (Na_(3)C_(6)H_(5)O_(7)) to essential medium. The antibacterial effect of Bacillus subtilis strain B115 on pathogenic Aeromonas was studied. The results showed different antibacterial effects of B115 on different aeromonads. There were obvious antibacterial effects on BSK-10 and CL990920, while no effect on the growth of TL970424.

Objective To investigate the cognitive dificiency characteristics and the neuro electrophysiological mechanism of sleep disordered breathing(SDB) in school-age children.Methods20 cases of SDB children and 20 cases of normal group at 6-8 years old participated in the continue performance test(CPT-AX).The amplitude and latency of N2,P3 of event related potentials(ERPs) were measured and analysed at Fz leads,and the behavioral results were recorded at the same time.ResultsThere were no significant differences between SDB group and normal group in behavioral correct number (36.10±4.69 vs 35.05±3.49),the reaction time ((523.77±68.73)ms vs (496.59±78.65)ms) and false alarm number (1.0 (0.25,3.75) vs 0.5 (0.00,3.00))(all P>0.05).The SDB group showed significant increase in Go-P3 amplitudes compared with the normal group((10.25±6.46)μV vs (6.56±4.63)μV,P<0.05).The Go-P3 latency in SDB group was significantly prolonged than that in the normal group((438.80±59.72)ms vs (406±36.30)ms,P<0.05),and the Nogo-N2 amplitude in SDB group significantly decreased compared with the normal group ((-12.46±4.75)μV vs (-15.50±3.82)μV,P<0.05).ConclusionThe children aged 6 to 8 years old with sleep disordered breathing consume more resources and time to complete the attention process,like a compensatory response.And during the monitoring process there is a resource shortage that results in obvious defect in process of inhibition.

The purpose of the experiment was to study the efficacy of edaravone in enhancing flap viability after ischemia/reperfusion (IR) and its mechanism.Forty-eight adult male SD rats were randomly divided into 3 groups:control group (n=16),IR group (n=16),and edaravone-treated IR group (n=16).An island flap at left lower abdomen (6.0 cm×3.0 cm in size),fed by the superficial epigastric artery and vein,was created in each rat of all the three groups.The arterial blood flow of flaps in IR group and edaravone-treated IR group was blocked for 10 h,and then the blood perfusion was restored.From 15 min before reperfusion,rats in the edaravone-treated IR group were intraperitoneally injected with edaravone (10 mg/kg),once every 12 h,for 3 days.Rats in the IR group and control group were intraperitoneally injected with saline,with the same method and frequency as the rats in the edaravone-treated IR group.In IR group and edaravone-treated IR group,samples of flaps were harvested after reperfusion of the flaps for 24 h.In the control group,samples of flaps were harvested 34 h after creation of the flaps.The content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) were determined,and changes in organizational structure and infiltration of inflammatory cells were observed by hematoxylin-eosin (HE) staining,apoptotic cells of vascular wall were marked by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay,and the apoptotic rate of cells in vascular wall was calculated.The ultrastructural changes of vascular endothelial cells were observed by transmission electron microscopy (TEM).Seven days after the operation,we calculated the flap viability of each group,and marked vessels of flaps by immunohistochemical staining for calculating the average number of subcutaneous vessels.The results showed that the content of MDA,the number ofmulticore inflammatory cells and apoptotic rate of cells in vascular wall in the edaravone-treated IR group were significantly lower than those in the IR group.The activity of SOD,flap viability and average number of subcutaneous vessels in the edaravone-treated IR group were significantly higher than those in the IR group.All the differences were statistically significant.The ultrastructure injury of vascular endothelial cells in the edaravone-treated IR group was slighter than that in IR group.It was concluded that edaravone can significantly enhance IR flap viability and protect flap vessels,which is related to scavenging oxygen free radicals,reducing the consumption of SOD,reducing the extent of lipid peroxidation and inflammation,and protecting functional structure of vessels in the early stages of reperfusion.
