AIMTo compare the intraoperative performance and postoperative outcome after microcoaxial torsional phacoemulsification using either a Kelman or balanced phaco *** were treated using 2.2 mm microcoaxial torsional phacoemulsification using either a 45-degree mini-flared Kelman® or a 45-degree Intrepid® Balanced phaco tip. Intraoperative measurements included total ultrasound (US) time, cumulative dissipated energy (CDE), torsional US time, and balanced salt solution (BSS) use. The central endothelial cell density (ECD) and central corneal thickness (CCT) were evaluated preoperatively and postoperatively 1, 7, and 30d after surgery using noncontact specular *** 116 enrolled eyes (116 patients) were divided equally between the Kelman and balanced tip groups. Intraoperative measurements showed significantly less total US time, torsional US time, CDE, and BSS use in the balanced group than in Kelman group (P<0.05). The total US time, torsional US time, CDE, and BSS use were 17.45±14.53s, 16.63±13.97s, 6.38±5.26, and 48.21±17.21 mL in the Kelman group and 11.39 ± 9.60s, 10.90 ± 9.25s, 4.04 ± 3.42, and 41.36 ± 12.70 mL in the balanced group, *** phacoemulsification performed with a balanced tip provided more effective lens removal with less total US time, torsional time, CDE, and BSS use, as well as similar changes in ECD with a Kelman tip in all cataract grades. This special designed phaco tip for torsional phacoemulsification provides an alternative phaco tip for many surgeons' preference with straight phaco tip.

AIM：To evaluate ocular penetration of topically applied 1% ***：Forty-two New Zealand White rabbits were divided into 3 groups. A 50 μL drop of 1% tigecycline was administered in group 1. In groups 2 and 3, the drop was administered every 15 min for 60min（keratitis protocol）. Aqueous humor samples in groups 1 and 2 were collected under general anesthesia at 15, 30, 45, 60, 120, and 180 min after the last drop. All animals in group 3 were euthanatized. Cornea, vitreous and blood samples were collected 60 and 120 min after the last drop. Tigecycline concentrations were measured using high performance liquid chromatography-mass spectrometry（LC-MS/MS）.RESULTS：The peak aqueous humor tigecycline concentration [mean 0.73±0.14 mg/L（SD） and 2.41±0.14 mg/L, respectively] occurred 45 min after topical drug application in groups 1 and 2. Group 3 mean values in the cornea, and vitreous, were 3.27±0.50 μg/g, and 0.17±0.10 mg/L at 60 min and 3.17±0.77 μg/g and 0.20±0.07 mg/L at 120 min, respectively. Tigecycline serum concentrations were ***：Tigecycline levels in the aqueous humor in groups 1 and 2, and in the cornea in group 3 exceeded the minimum inhibitory concentrations of most grampositive organisms that cause bacterial keratitis and endophthalmitis.

The others remained unaffected. Bacterial groups with initially marginal concentrations (9/mL) demonstrated no response to humic acids. The concentrations of pioneer groups of Bifidobacteriaceae, Enterobacteriaceae and Clostridium difficile increased but the observed differences were statistically not *** acids have a profound effect on healthy colonic microbiome and may be potentially interesting substances for the development of drugs that control the innate colonic microbiome.

目的:研究后囊膜混浊(posterior capsular opacity,PCO)及其治疗对使用谱域光学相干断层扫描(spectral domain optical coherence tomography,SD-OCT)测量视网膜神经纤维层(retinal nerve fiber layer,RNFL)厚度的影响。方法:使用SD-OCT测量50例接受Nd:YAG激光后囊膜切开术患者术前和术后RNFL厚度。通过信噪比(signal to noise ratio,SNR)等级,将患者分为组1(SNR 3和4)、组2(SNR 5和6)及组3(SNR 7和8)。对侧眼作为对照组。结果:接受了Nd:YAG激光后囊膜切开术的眼BCVA、SNR和RNFL均值显著增加。组1和组2激光治疗前后BCVA、SNR和RNFL均值显著不同。尽管组3中患者治疗前后BCVA和SNR均值显著不同,RNFL厚度在治疗前后没有显著差异。结论:PCO对OCT图像质量有影响。所有接受后囊膜切开术的患者,术后SNR较术前有所改善。治疗前SNR7在以下的患者中,RNFL厚度在患者接受Nd:YAG激光后囊膜切开术后显著提高。

窄波UVB联合局部外用钙泊三醇治疗白癜风

世界核心医学期刊文摘（皮肤病学分册） 2006年第9期2卷 4-4页

作者： goktas E.O. Aydin F. Senturk N. 冯义国 Ondokuz Mayis University School of Medicine Department of Dermatology TR- 55139 Kurupelit Samsun Turkey

Background: Narrow band ultraviolet B (NB-UVB) phototherapy has been used successfully for the treatment of vitiligo. Recently, topical calcipotriol has also been claimed to be effective, either as monotherapy or as a part of combination therapies. Objective: The aimof the present studywas to compare the clinical efficacy of NB-UVB and NB-UVB plus topical calcipotriol in the treatment of vitiligo. Methods: NB-UVB treatment was given to 24 patientswith generalized vitiligo three times weekly. Topical calcipotriol cream was only applied to the lesions located on the right side of the body. Treatment was continued for 6 months. Treatment efficacy was evaluated by determining the average response rates of the lesions at 3-month intervals. Result: The average response rates of patients receiving combination of NB-UVB plus calcipotriol and NB-UVB alone were 51 ± 19.6% and 39 ± 18.9% , respectively. The median cumulative UVB dose and number of UVB exposures for initial repigmentation were 6345 mj/cm2 (range; 2930- 30980) and 18 (range; 12- 67) for the combination therapy, and 8867.5 mj/cm2 (range; 2500- 30980) and 24 (range; 15- 67) for the narrow band UVB therapy, respectively. Conclusions: These findings indicate that concurrent topical calcipotriol potentates the efficacy of NB-UVB in the treatment of vitiligo. This combination not only provides earlier pigmentation with lower total UVB dosage and less adverse UVB effects, but also reduces the duration and cost of treatment as well.
