Objective To study the safety and efficiency of transurethral electrochemical therapy (ECT) on benign prostatic hyperplasia (BPH). Methods An experimental electrechomical therapy on prostate has been carred out in 12 dogs.The prostate tissue and the nearly organs were studied for any morphological changes.On the basis of the experiment,ECT was then carried out for 11 patients suffered from BPH.The relevant parameters were assessed. Results In the experimental group,good therapeutic effect was achieved if the electrode was 10 mm shorter than the prostatic urethra.On the other hand if the electrode was 10 mm longer than the prostatic urethera,urethro-rectal fistula and urine incontinence might result.In the clinical group,the effective rate was 82% with no complication observed.Before the treatment RI was 0.70?0.04 and 2 weeks after treatment 0.73?0.03;IPSS 26.7?6.2 and 19.5?4.7;QOL 4.9?0.5 and 3.5?0.6;Qmax (7.8?2.0) and (12.4?3.1)ml/s;PVR (129.1?40.8) and (64.1?27.4)ml;V (48.0?13.1) and ( 47.0?13.5)ml.There was significant difference of IPSS,QOL,Qmax,PVR,RI before and after treatment (P0.05). Conclusions With proper maniputation and adequate length of the electrode used,ECT is a safe,efficient and mini-invasive means for treating BPH in high risk patients nontolerable to open surgery.

AIM: To compare the efficiency and safety of torsional phacoemulsification with or without intelligent phacoemulsification ( IP ) software in hard nucleus cataract extraction.
METHODS: Ninety two eyes with Ⅳ - Ⅴ grades cataracts were enrolled in this randomized prospective study. Operated eyes were divided into two groups -those operated without IP software ( non- IP group, n =43) and those operated using IP software (IP group, n =49 ). The two groups were compared in terms of ultrasound time (UST) and cumulative dissipated energy (CDE). Post- operative outcome measures included the corneal edema and best-corrected visual acuity (BCVA) at 1,7d and 3mo postoperatively, corneal endothelial cell density and percentage of hexagonal cell at 7d and 3mo postoperatively.
RESULTS: UST was measured as 52. 51±9. 64s in non-IP Group and 48. 79±7. 13s in IP Group (P = 0. 030). CDE was 15. 78±3. 73% in non-IP Group and 14. 29±2. 77% in IP Group ( P = 0. 026). At the first postoperative day, the rate of BCVA>0. 1 in non-IP Group was 56%, and the rate in IP Group was 79% (P= 0. 066). Corneal edema in non-IP Group was 2. 98±0. 77 scores, and in IP Group it was 2. 61±0. 64 scores (P = 0. 021). At the postoperative 7 and 30d, the BCVA and corneal edema were no differences between two groups. At the postoperative 7d, corneal endothelial cell density in non- IP Group were 2497. 95 ±211. 48 / mm2 , less than 2586. 26±154. 71 / mm 2 in IP Group (P= 0. 029);percentage of hexagonal cell in IP group was 48. 33±8. 69%,higher than 44. 19±9. 48% of non-IP group(P= 0. 030).CONCLUSION: In hard nucleus cataract extraction, the IP software can combine the advantages of the two kinds of ultrasonic modes, which is more effective with lower ultrasound energy and less injury for the corneal endothclium, and is helpful for the recovery of vision at early stage after surgeries.

Objective To compare contrast-enhanced ultrasonography (CEUS), contrast-enhanced CT (CECT) and combined detection of two methods in the diagnosis of small renal masses, and differential diagnosis of different types of small renal masses by CEUS. Methods In 95 cases of small renal masses, there were 79 patients with small renal cell carcinoma and 16 patients with benign tumor. The diagnostic results of the three methods were compared based on the pathological results, which were used as thegold standardfor the diagnostic efficacy. The ROC curve was drawn, and the area under the curve (AUC) was compared. The characteristics of the two groups were analyzed and compared by Q-Lab software in CEUS. The angiographic parameters included arrival time (AT), time to peak (TTP) and peak intensity (PI). CEUS patterns for several pathologic types of renal tumors with larger sample sizes were compared. The characteristic manifestations of small renal masses under CEUS were analyzed. Results The accuracy, sensitivity, specificity, positive predictive value, negative predictive value and AUC of CEUS were 87.37%, 93.67%, 56.25%, 91.36%, 64.29%and 0.750, the values for CECT were 88.42%, 93.67%, 62.50%, 92.50%, 66.67%and 0.775, and the values for combined detection of two methods were 95.79%, 98.73%, 81.25%, 96.30%, 92.86%and 0.869 respectively. The sensitivities of the three methods were high, but the specificities were the same. The combined detection showed better diagnostic efficacy than that of single diagnostic method. The AT and TTP of CEUS were earlier in small renal carcinoma group than those of benign nephrotic group, and PI was higher than that of benign nephrotic group (P<0.05). There were significant differences in the contrasts ofcontrast enhancement methods between clear cell carcinoma, papillary cell carcinoma, chromophobe cell carcinoma, and angiomyolipoma (P<0.01). There was little difference in contrast enhancement between the other types of carcinoma. False envelope can be observed by CEUS.'Cystic area'of the detection rate was increased significantly by CEUS than that of conventional ultrasound. Conclusion Combined detection of CEUS and CECT can improve the diagnostic accuracy of small renal tumors. CEUS has great clinical value in the differential diagnosis of small renal masses, which is worthy of clinical promoting.

Objective To explore the susceptibility of Candida albicans biofilms to micafungin. Methods In vitro model of C. Albicans biofilm was established in 96-well microtiter plates with 30 C. Albicans isolates from the Department of Mycology, Changhai Hospital, Shanghai. The susceptibility of C. Albicans biofilms to fluconazole, amphotericine B and micafungin was evaluated by colorimetric XTT-reduction assay. Sessile MIC80 (SMIC80), defined as the lowest antifungal concentration at which an 80% reduction in fungal growth was achieved, was determined. Results Of the 30 C. Albicans isolates grown in sessile states, all were resistant to fluconazole (SMIC80≥64 μg/mL), 4 sensitive to amphotericine B (SMIC80≤1 μg/mL), 26 resistant to amphotericine B (SMIC80 > 1 μg/mL), 27 sensitive to micafungin (SMIC80 < 16 μg/mL), 3 resistant to micafungin (SMIC80 >16 μg/mL). Statistical analysis revealed a significant difference in the activity against C. Albicans biofilms between micafungin and fluconazole (χ2=736.36, P<0.01), micafungin and amphotericine B (χ2=529.95, P<0.01), but not between anphotericine B and fluconazole (χ2=2.29, P>0.05). Conclusion C. Albicans biofilms are resistant to routine antifungal agents such as fluconazole and amphotericine B, but relatively more sensitive to micafungin.
