Objective To evaluate the application of tendency-oriented perimetry (TOP) in detecting the visual function of glaucoma. Methods The traditional threshold perimetry (Normal/Normal strategy) and TOP (TOP/Normal strategy) carried out by Octopus 101 perimetry were used to examine the visual field of 20 normal subjects (20 eyes), 32 cases (32 eyes) of primary open-angle glaucoma (POAG), and 14 cases (14 eyes) of suspected POAG, respectively. The visual field outcomes, indices, point by point threshold variability and defective points of the two perimetries were compared and analysed. Results The negative rate of TOP was 90% in normal subjects. The positive rate of TOP was 75% in POAG , and 100% in middle and late stage of POAG. The visual field indices of two perimetries were positively correlated, with mean sensitivity (MS) of r=0.9335, mean defect (MD) of r=0.9189, and loss variance (LV) of r=0.9621. The point by point threshold variability and defective points of TOP were higher than those of traditional threshold perimetry, but the difference between the two perimetries was not significant (P=0.2019, P=0.4448). Conclusion The visual field indices of TOP and traditional threshold perimetry are positively correlated. The sensitivity and reproducibility of TOP are high in detecting the visual function of middle and late stage of POAG.

Objective To detect the expression of Bmi-1 and p16 gene in transitional cell carcinoma of bladder(TCC) tissue and explore its clinical significance.Methods The expression of Bmi-1 and p16 gene were detected by real-time quantitative polymerase chain reaction in 61 cases of TCC tissue and 12 cases of normal bladder tissue.Results The expression of Bmi-1 gene in TCC tissue was significantly higher than that in normal bladder tissue (0.242 ± 0.129 vs.0.031 ± 0.011),and the expression of p16 gene was significantly lower than that in normal bladder tissue (0.059 ± 0.021 vs.0.165 ± 0.029),there was significant difference (P < 0.05).The expression of Bmi-1 and p16 gene were highly correlated with pathological grades,clinical stages and tumor recurrence (P < 0.05 or < 0.01).But there were not correlated with age and gender (P > 0.05).There was a negative correlation between the expression of Bmi-1 gene and p16 gene in TCC tissue(rs =-0.714,P< 0.05).Conclusions Bmi-1 gene high expression and p16 gene low expression may be involved in the occurrence and development process of TCC.Bmi-1 may decrease the expression of p 16 gene in some ways,and then lead to the occurrence and development of TCC.

The fermentation of Bacillus cereus DLSL-2 was investigated through single-factor test. The optimized fermentation conditions are: temperature 30℃,initial pH 7.0,250 r/min. Uniform design was used in shaking flask to optimize the fermentation medium of bacillus cereus . The most suitable medium was identified as follows:4.88% defated soybean power ,1.45% maize starch, 0.106% K 2HPO 4, 1.78% yeasts extract, 5.6% inoculum. the optimized medium allowed the B.cereus biomass concentration to be increased from 3.2?109 cfu/mL to 7.1?109 cfu/mL.

A new flavonoid glycoside, (-)-2S-8-methyl-5,7,4'-trihydroxyflavanone-7-O-β-D-glucopyranoside (1), along with five known ones, quercetin-3-O-(2"-galloyl)-α-L-arabinoside (2), kaempferol-3-O-α-L-arabinoside (3), guaijaverin (4), trifolin (5) and hyperin (6), was isolated from the leaves of Eucalyptus robusta. Their structures with absolute configurations were elucidated by NMR, HR-ESI-MS, CD spectra data and physicochemical methods. In addition, 2-6 were isolated from E. robusta for the first time.

Objective To investigate voicing changes of adult patients with obstructive sleep apnea hypopnea syndrome (OSAHS) before and after H-uvulopalatopharyngoplasty (H-UPPP). Methods 56 adult OSAHS pa-tients and 40 healthy people were included in the study. Acoustic parameters and formant frequencies were measured for each patient before and after H- UPPP, and also for the control group. Results Acoustic parameters: each group demonstrated no differences in all the parameters except for normalized noised energy (NNE). NNE increased after H-UPPP. Formant frequency: F1, B1, F2, B2, F3 of OSAHS patients were significantly lower than normal control. There was no significant difference in the formant frequency before operation and one week after; however, F1 and F2 were lower than the normal control one week after surgery. One month after surgery, F1 and F2 were ob-viously higher than that obtained in one week. All the other parameters compared with normal controls showed no significant discrepancies. Conclusion Acoustic characteristics of adult OSAHS patients were different from healthy person. After H-UPPP, the vocal tracts of patients changed, thus causing improvement to the acoustic parameters and voicing qualities, especially at the formant frequency. After the surgery, the formant frequencies of the patients increased gradually to the range of healthy people.

Objective To investigate the incidence of infection and the effect of anti-infection prophylaxis in renal transplanted patients after Basiliximab induction therapy. Methods A total of 204patients who have received renal transplantation and Basiliximab induction therapy from January 1,2001 to December 31, 2010 in our hospital have been retrospective analysed in this study. These patients were divided into a prophylaxis group (118 cases) with Ganciclovir + Sulfadiazine +Trimethoprim therapy and a control group (86 cases) without any anti-infection prophylaxis.Furthermore, 440 transplanted patients in the same peroid without any induction therapy were also analysed. They were also devided into two groups: an anti-infection prophylaxis group (206 cases)and a control group (234 cases) without any anti-infection prophylaxis. Results In the prophylaxis group with Basiliximab induction therapy, there were 23 patients (19. 5 %, 23/118)experienced hospitalization due to infection, 3 cases (13. 0 %,3/23) among them were severe infection, and 3patients (13.0 %, 3/23) died from vital infection. In the non-prophylaxis control group with Basiliximab induction therapy, 27 patients (31.4 %, 27/86) had infection complication, 7 patients (25.9 % ,7/27) among them were severe infection, and 4 patients(14. 8 % ,4/27)died. The incidence of infection between the above two groups is significantly different (P<0. 05). In the prophylaxis group without induction therapy, the incidence of infection was 15.0 % (31/206), there were no severe infection cases but 7 patients (22. 6 %, 7/31) died from infection. In the non-prophylaxis control group without induction therapy, the incidence of infection was 12. 8 % (30/234), 3 cases among them were severe infection(10. 0 %,3/30)and 5 patients died from infection (16. 7 %, 5/30).The incidence of infection in Basiliximab induced patients without anti-infection prophylaxis is significantly higher than that in patients without induction therapy and anti-infection prophylaxis (31.4 % vs. 12.8 %,P<0.01). Conclusion Basiliximab induction therapy increased the risk of infection, but not the rate of mortality. It is necessary to give anti-infection prophylaxis in renal transplanted patients with Basiliximab induction therapy.
